    To improve the energy utilization of magnetic field generators for biological applications, a multifunctional energy-saving magnetic field generator (ESMFG) is presented. It is capable of producing both an alternating magnetic field (AMF) and a bipolar pulse magnetic field (BPMF) with high energy-saving and energy-reuse rates. Based on a theoretical analysis of an RLC second-order circuit, the energy-saving and energy-reuse rates of both types of magnetic fields can be calculated and are found to have acceptable values. The results of an experimental study using the proposed generator show that for the BPMF, the peak current reaches 130 A and the intensity reaches 70.3 mT. For the AMF, the intensity is 11.0 mT and the RMS current is 20 A. The energy-saving and energy-reuse rates for the AMF generator are 61.3% and 63.5%, respectively, while for the BPMF generator, the energy-saving rate is 33.6%. Thus, the proposed ESMFG has excellent potential for use in biomedical applications.

    The primary goals of this research effort are to develop, evaluate, and demonstrate a very practical HVAC system for classrooms that consistently provides classrooms (CRs) with the quantity of ventilation in current minimum standards, while saving energy, and reducing HVAC-related noise levels. This research is motivated by the public benefits of energy efficiency, evidence that many CRs are under-ventilated, and public concerns about indoor environmental quality in CRs. This document provides a summary of the detailed plans developed for the field study that will take place in 2005 to evaluate the energy and IAQ performance of a new classroom HVAC technology. The field study will include measurements of HVAC energy use, ventilation rates, and IEQ conditions in 10 classrooms with the new HVAC technology and in six control classrooms with a standard HVAC system. Energy use and many IEQ parameters will be monitored continuously, while other IEQ measurements will be will be performed seasonally. Continuously monitored data will be remotely accessed via a LonWorks network. Instrument calibration plans that vary with the type of instrumentation used are established. Statistical tests will be employed to compare energy use and IEQ conditions with the new and standard HVAC systems. Strengths of this study plan include the collection of real time data for a full school year, the use of high quality instrumentation, the incorporation of many quality control measures, and the extensive collaborations with industry that limit costs to the sponsors.

    This report provides results from an evaluation PNNL conducted of a spectrally enhanced lighting demonstration project. PNNL performed field measurements and occupant surveys at three office buildings in California before and after lighting retrofits were made in August and December 2005. PNNL measured the following Overhead lighting electricity demand and consumption, Light levels in the workspace, Task lighting use, and Occupant ratings of satisfaction with the lighting. Existing lighting, which varied in each building, was replaced with lamps with correlated color temperature (CCT) of 5000 Kelvin, color rendering index (CRI) of 85, of varying wattages, and lower ballast factor electronic ballasts. The demonstrations were designed to decrease lighting power loads in the three buildings by 22-50 percent, depending on the existing installed lamps and ballasts. The project designers hypothesized that this reduction in electrical loads could be achieved by the change to higher CCT lamps without decreasing occupant satisfaction with the lighting.

    Making the energy consumption more efficient in Denmark by means of energy saving are connected to the Danish government's overall National Growth Strategy. A reduced consumption of energy as a result of economic attractive energy saving initiatives leads to reduced energy costs and consequently an improvement of Denmark's competitive power. Furthermore, reducing the energy consumption decreases the vulnerability towards rising energy prices, and the security of supplies is increased. Finally energy conservation serves as a means of reducing environmental impact from the energy sector. Energy consumption is not damaging to the environment in itself, however, to the extent that energy consumption causes negative impact on the environment, e.g. through discharge of environmentally damaging substances generated during energy production, a reduction of the energy consumption will benefit the environment. Energy saving in itself does not lead to a decrease in CO{sub 2} emission in Denmark unless it is accompanied by an adjustment of CO{sub 2} quotas on production of electricity. The Danish Government emphasizes that the energy saving efforts are cost-effective both for the society and for the consumers. The energy saving report contains an updated projection of the Danish energy consumption and an evaluation of the impacts of the energy saving efforts. The impacts of more effective end use of energy are described, and an account of the barriers preventing the realization of a number of potential economic attractive energy saving initiatives is made. Finally the energy saving report presents a number of proposals for new energy saving initiatives. (BA)

  7. Measuring industrial energy savings

    Accurate measurement of energy savings from industrial energy efficiency projects can reduce uncertainty about the efficacy of the projects, guide the selection of future projects, improve future estimates of expected savings, promote financing of energy efficiency projects through shared-savings agreements, and improve utilization of capital resources. Many efforts to measure industrial energy savings, or simply track progress toward efficiency goals, have had difficulty incorporating changing weather and production, which are frequently major drivers of plant energy use. This paper presents a general method for measuring plant-wide industrial energy savings that takes into account changing weather and production between the pre and post-retrofit periods. In addition, the method can disaggregate savings into components, which provides additional resolution for understanding the effectiveness of individual projects when several projects are implemented together. The method uses multivariable piece-wise regression models to characterize baseline energy use, and disaggregates savings by taking the total derivative of the energy use equation. Although the method incorporates search techniques, multi-variable least-squares regression and calculus, it is easily implemented using data analysis software, and can use readily available temperature, production and utility billing data. This is important, since more complicated methods may be too complex for widespread use. The method is demonstrated using case studies of actual energy assessments. The case studies demonstrate the importance of adjusting for weather and production between the pre- and post-retrofit periods, how plant-wide savings can be disaggregated to evaluate the effectiveness of individual retrofits, how the method can identify the time-dependence of savings, and limitations of engineering models when used to estimate future savings

    To improve the efficiency of the hydraulic drive system in field walking robot, this paper proposed a novel hydraulic system based on two-stage pressure source. Based on the analysis of low efficiency of robot single-stage hydraulic system, the paper firstly introduces the concept and design of two-stage pressure source drive system. Then, the new hydraulic system energy-saving control is planned according to the characteristics of walking robot. The feasibility of the new hydraulic system is proved by the simulation of the walking robot squatting. Finally, the efficiencies of two types hydraulic system are calculated, indicating that the novel hydraulic system can increase the efficiency by 41.5%, which can contribute to enhance knowledge about hydraulic drive system for field walking robot.

This research is motivated by the public benefits of energy efficiency, evidence that many classrooms are under-ventilated, and public concerns about indoor environmental quality in classrooms. This report presents an interim status update and preliminary findings from energy and indoor environmental quality (IEQ) measurements in sixteen relocatable classrooms in California. The field study includes measurements of HVAC energy use, ventilation rates, and IEQ conditions. Ten of the classrooms were equipped with a new HVAC technology and six control classrooms were equipped with a standard HVAC system. Energy use and many IEQ parameters have been monitored continuously, while unoccupied acoustic measurements were measured in one of four planned seasonal measurement campaigns. Continuously monitored data are remotely accessed via a LonWorks{reg_sign} network and stored in a relational database at LBNL. Preliminary results are presented here.

    This technical brief explains the concepts of energy savings lifetimes and savings persistence and discusses how program administrators use these factors to calculate savings for efficiency measures, programs and portfolios. Savings lifetime is the length of time that one or more energy efficiency measures or activities save energy, and savings persistence is the change in savings throughout the functional life of a given efficiency measure or activity. Savings lifetimes are essential for assessing the lifecycle benefits and cost effectiveness of efficiency activities and for forecasting loads in resource planning. The brief also provides estimates of savings lifetimes derived from a national collection of costs and savings for electric efficiency programs and portfolios.

  12. Risk transfer via energy-savings insurance

    Mills, Evan

    2003-01-01

    Among the key barriers to investment in energy efficiency are uncertainties about attaining projected energy savings and potential disputes over stipulated savings. The fields of energy management and risk management are thus intertwined. While many technical methods have emerged to manage performance risks (e.g. building diagnostics and commissioning), financial methods are less developed in the energy management arena than in other segments of the economy. Energy-savings insurance (ESI) - formal insurance of predicted energy savings - transfers and spreads both types of risk over a larger pool of energy efficiency projects and reduces barriers to market entry of smaller energy service firms who lack sufficiently strong balance sheets to self-insure the savings. ESI encourages those implementing energy-saving projects to go beyond standard measures and thereby achieve more significant levels of energy savings. Insurance providers are proponents of improved savings measurement and verification techniques, as well as maintenance, thereby contributing to national energy-saving objectives. If properly applied, ESI can potentially reduce the net cost of energy-saving projects by reducing the interest rates charged by lenders, and by increasing the level of savings through quality control. Governmental agencies have been pioneers in the use of ESI and could continue to play a role

    A key issue in Eastern Europe is the adjustment of prices from the former COMECON level to a level conforming with free market conditions. In the case of household heating, this issue involves the removal of government subsidies leading to sharply increasing prices, metering of individual consumption, improving the efficiency of energy production, distribution and use - where savings of 30-50% in each link are technically feasible - thereby providing a potential for a adapting consumption patterns to higher energy prices, provided that funds are available. Currently, investment in commercial heat production and distribution systems have received substantial international support - whereas investment in reduction of demand has been little exploited. The Revolving Fund for Energy Savings in Polish Households is a concept for efficient financing of small-scale projects. It aims at financing, on the level of housing cooperatives, on the basis of a simplified lending and project evaluation procedure, well suited to current Polish conditions or an organizationally and financially weak banking system and little developed technical knowledge in the field of energy saving. A general introduction to the issue is given and technical problems are elaborated. The implementation of Energy Savings in Housing seen from the banking point of view, and a current pilot scheme for financing, are described. (AB)

    Full Text Available Various types of sensors technologies, such as machine vision and global positioning system (GPS have been implemented in navigation of agricultural vehicles. Automated navigation systems have proved the potential for the execution of optimised route plans for field area coverage. This paper presents an assessment of the reduction of the energy requirements derived from the implementation of optimised field area coverage planning. The assessment regards the analysis of the energy requirements and the comparison between the non-optimised and optimised plans for field area coverage in the whole sequence of operations required in two different cropping systems: Miscanthus and Switchgrass production. An algorithmic approach for the simulation of the executed field operations by following both non-optimised and optimised field-work patterns was developed. As a result, the corresponding time requirements were estimated as the basis of the subsequent energy cost analysis. Based on the results, the optimised routes reduce the fuel energy consumption up to 8%, the embodied energy consumption up to 7%, and the total energy consumption from 3% up to 8%.

    2013-01-01

    This study examines the influences of financial and non-financial factors on electricity-conservation behaviour. A random sample of 236 Japanese households participated in the field experiment and the participants were offered two interventions, such as monetary rewards, depending on their reduction in electricity consumption and comparative feedback. The average saving rates of the (i) reward-intervention group (5.9%) and the (ii) reward with comparative feedback group (8.2%) are statistically larger than those of the (iii) control group (1.7%). Our study demonstrates the following. First, our econometric analysis confirmed a significant response by households to financial incentives but a more inconclusive response to the treatment that provided non-financial, additional information. Second, we found a positive influence of treatment externalities across time and households on energy saving. Third, there is a heterogeneous treatment effect in the reward-intervention group, with the households having a high New Ecological Paradigm (NEP) score being more likely to respond to the reward programme and save electricity than those that do not. Finally, and most interestingly, differences in responses to the questionnaire before and after the experiment suggest that the participants had underestimated the marginal costs of saving electricity before they actually started to do so. - highlights: • We studied the effects of (non-)financial factors on household electricity use. • Financial factors had a significant effect; non-financial ones were inconclusive. • Externalities had a positive effect across time and households on saving energy. • There is a heterogeneous treatment effect in financial-reward intervention. • Before the experiment, participants underestimated the marginal costs of saving electricity

    Full Text Available This article analyses methods of energy efficiency stimulation in the European Union. The author investigates basic areas of the EU activity; in particular, the author estimates results of implementation of the Energy Star program, new provisions of labeling of energy-using products, measures to increase energy efficiency in buildings. The paper also analyzes the provisions of the Directive 2012/27 that is the first EU document, providing for a comprehensive approach to energy saving at all stages: production, transformation and consumption. Today EU policy includes: 7 a general political and regulatory framework laid down by the European action plan on energy efficiency and Directive 2012/27; 2 national action plans on energy efficiency, which should be in line with indicative targets set at the EU level; 3 special EU documents in key areas of energy efficiency (buildings, energy-consuming equipment etc.; 4 accompanying instruments, such as target funding, information dissemination, support of specialized networks. The paper gives a comprehensive analysis of the key methods of implementation of EU policy in the area of energy saving. The author concludes that EU operates within the framework of the open method of coordination. The system of mandatory/voluntary technical standards has allowed to achieve significant success, but indicative planning and monitoring of national actions are not completely effective. In the long term EU policy in the area of energy efficiency is restrained by member states unwillingness to delegate to the European Union a more detailed powers in this field and to give the EU bodies facilities to execute more strict control. In the short term - in conditions of economic crisis, the EU countries are not ready to invest significant budget funds in projects with long payback period.

    In the transition towards a 100% renewable energy system, energy savings are essential. The possibility of energy savings through conservation or efficiency increases can be identified in, for instance, the heating and electricity sectors, in industry, and in transport. Several studies point...... to various optimal levels of savings in the different sectors of the energy system. However, these studies do not investigate the idea of energy savings being system dependent. This paper argues that such system dependency is critical to understand, as it does not make sense to analyse an energy saving...... without taking into account the actual benefit of the saving in relation to the energy system. The study therefore identifies a need to understand how saving methods may interact with each other and the system in which they are conducted. By using energy system analysis to do hourly simulation...

The fields of energy management and risk management are thus intertwined. While many technical methods have emerged to manage performance risks (e.g. building commissioning), financial risk transfer techniques are less developed in the energy management arena than in other more mature segments of the economy. Energy Savings Insurance (ESI) - formal insurance of predicted energy savings - is one method of transferring financial risks away from the facility owner or energy services contractor. ESI offers a number of significant advantages over other forms of financial risk transfer, e.g. savings guarantees or performance bonds. ESI providers manage risk via pre-construction design review as well as post-construction commissioning and measurement and verification of savings. We found that the two mos t common criticisms of ESI - excessive pricing and onerous exclusions - are not born out in practice. In fact, if properly applied, ESI can potentially reduce the net cost of energy savings projects by reducing the interest rates charged by lenders, and by increasing the level of savings through quality control. Debt service can also be ensured by matching loan payments to projected energy savings while designing the insurance mechanism so that payments are made by the insurer in the event of a savings shortfall. We estimate the U.S. ESI market potential of $875 million/year in premium income. From an energy-policy perspective, ESI offers a number of potential benefits: ESI transfers performance risk from the balance sheet of the entity implementing the energy savings project, thereby freeing up capital otherwise needed to ''self-insure'' the savings. ESI reduces barriers to market entry of smaller energy services firms who do not have sufficiently strong balance

    2005-01-01

    This work is focused on two ways of studying the reduction of the aerodynamic resistance of a van and the energy saving for a van with a dome. The first approach is the three dimensional (3-D) numerical simulation, and the other is the wind tunnel experiment. The relationship between the coefficient of aerodynamic resistance and the geometric parameters of the dome is obtained. We also analyzed the mechanism by which a dome can reduce the aerodynamic resistance acting on a van. Design for the improvement of a van can benefit from this work. The RNG k-ε turbulence models are adopted in the computation. The momentum method is used to calculate the coefficient of resistance. These have resulted in improvement of the computation accuracy. Flow maps drawn on the basis of the computed results can offer a reliable method to study the flow field around a van. The computed results can give a reference for study of the aerodynamic resistance reduction on a van for energy saving. The maximum decrease of the coefficient of aerodynamic resistance is 21.5% after a dome is installed on a van. The experiment also proves that the calculation using RNG k-ε turbulence models is more accurate for such a separated fluid around a van. The error of the calculations using RNG k-ε turbulence models is decreased by 6% compared with that using standard k-ε turbulence models

    A number of impediments have discouraged federal agencies from using shared energy savings contracts. As of November 30, 1988, only two federal agencies - the U.S. Postal Service (USPS) and the Department of the Army -had awarded such contracts even though they can yield significant energy and cost savings. The three major impediments we identified were uncertainty about the applicability of a particular procurement policy and practice, lack of management incentives, and difficulty in measuring energy and cost savings. To address the first impediment, the Department of Energy (DOE) developed a manual on shared energy savings contracting. The second impediment was addressed when the 100th Congress authorized incentives for federal agencies to enter into shared savings contracts. DOE addressed the third impediment by developing a methodology for calculating energy consumption and cost savings. However, because of differing methodological preferences, this issue will need to be addressed on a contract-by-contract basis. Some state governments and private sector firms are using performance contracts to reduce energy costs in their buildings and facilities. We were able to identify six states that were using performance contracts. Five have established programs, and all six states have projects under contract. The seven energy service companies we contacted indicated interest in federal shared energy savings contracting

    A demonstration of low-cost insulation and weatherization techniques was a part of phase 1 of the Krakow Clean Fossil Fuels and Energy Efficient Project. The objectives were to identify a cost-effective set of measures to reduce energy used for space heating, determine how much energy could be saved, and foster widespread implementation of those measures. The demonstration project focused on 4 11-story buildings in a Krakow housing cooperative. Energy savings of over 20% were obtained. Most important, the procedures and materials implemented in the demonstration project have been adapted to Polish conditions and applied to other housing cooperatives, schools, and hospitals. Additional projects are being planned, in Krakow and other cities, under the direction of FEWE-Krakow, the Polish Energie Cities Network, and Biuro Rozwoju Krakowa.

    The paper first describes the concepts and methods around energy saving, such as energy chain, energy services, end-use technologies, secondary energy, etc. Next are discussed the problems of defining and adding energy services and hence end-use energy efficiency or intensity. A section is devoted...... to what is termed lifestyle efficiency, including the cultural values and the ability of the economy to provide the services wanted. As explained, integrated resource planning with its optimizing the whole energy chain cannot be combined with sub-optimizing part of it, for instance the supply technology...... only. The need for including also the economic policy in the energy planning is illustrated with what is termed the efficiency pittfall. This points towards difficulties in imaging an integrated resource planning combined with a liberalized market. The three variable parameters, population, energy...

A potential to solve energy supply problems is strongly correlated with the ability to ensure the innovative development of economy for efficient and economical use of existing and imported energy resources. The ways for reducing of energy resource consumption have been suggested. Creation of technological conditions for the use of alternative energy sources is considered to be rational also. The development of renewable sources of energy (alternative and renewable energy sources will provide a significant effect in reducing the use of traditional energy sources, harmful emissions and greenhouse gas. Under these conditions, increasing of energy efficiency of economy and its competitiveness can be real. Improvement of environmental and social conditions of citizens of the country will mark a positive step towards the EU, and also will cancel some problems of the future generation.

  10. Energy saving estimation on radiation process

    1982-01-01

    The Irradiation Application Group, Radiation Utilization Study Committee, Japan Atomic Industrial Forum Inc., has examined radiation process from the viewpoint of energy saving for one year. In this paper, the results related to the cross-linking of cable coating and rubber are reported. In these fields, the chemical cross-linking is made generally by mixing cross-linking agents in raw materials and passing through the atmosphere with large heat source, but the effect of energy saving when this process is substituted with electron beam cross-linking was calculated for trial. The application of electron beam irradiation to the reform of cable coating has been carried out from old time, but it is mostly for appliance wires of up to 1.5 mm thickness, and it has not been applied to high voltage power cables. The present state of the cross-linking method for high voltage power cables, the comparison of electron beam cross-linking and other methods from the viewpoint of energy saving and others are described. It was shown that the electron beam cross-linking is very effective means for energy saving, but the actual application in Japan is still few. (Kako, I.)

  14. Potential Energy Cost Savings from Increased Commercial Energy Code Compliance

    Rosenberg, Michael I.; Hart, Philip R.; Athalye, Rahul A.; Zhang, Jian; Cohan, David F.

    2016-08-22

    An important question for commercial energy code compliance is: “How much energy cost savings can better compliance achieve?” This question is in sharp contrast to prior efforts that used a checklist of code requirements, each of which was graded pass or fail. Percent compliance for any given building was simply the percent of individual requirements that passed. A field investigation method is being developed that goes beyond the binary approach to determine how much energy cost savings is not realized. Prototype building simulations were used to estimate the energy cost impact of varying levels of non-compliance for newly constructed office buildings in climate zone 4C. Field data collected from actual buildings on specific conditions relative to code requirements was then applied to the simulation results to find the potential lost energy savings for a single building or for a sample of buildings. This new methodology was tested on nine office buildings in climate zone 4C. The amount of additional energy cost savings they could have achieved had they complied fully with the 2012 International Energy Conservation Code is determined. This paper will present the results of the test, lessons learned, describe follow-on research that is needed to verify that the methodology is both accurate and practical, and discuss the benefits that might accrue if the method were widely adopted.

    The Czechoslovak/Danish project on energy savings in buildings proves that it is possible to save up to 30% of the energy in buildings. 10% can be saved at an investment of 27 bill KCS. The total investment that is needed to save 30% is 140 bill KCS. Further energy savings can be obtained through more energy efficient supply systems. Information dissemination is important for the energy saving programme as are economic incentives. Investments in energy savings should be profitable for the investor, but this is not the case in the Czech and Slovak republics today. Changes are needed. Energy prices are still to low, compared to investment costs. Financial possibilities are not satisfactory for private investors. Price systems are not favourable to investment in energy savings. Training is needed for boiler men and energy consultants. Legislation is essential for the support of the full range of activities in the energy sector. Research and Development activities must back up the development of the sector. Pilot projects can illuminate the savings potential. The production of technical equipment for control and metering and production of insulation materials must be promoted. (AB)

    2014-07-01

    Expanding on previous research by PARR, this study compares measure packages installed during 800 Illinois Home Performance with ENERGY STAR (IHP) residential retrofits to those recommended as cost-optimal by Building Energy Optimization (BEopt) modeling software. In previous research, cost-optimal measure packages were identified for fifteen Chicagoland single family housing archetypes, called housing groups. In the present study, 800 IHP homes are first matched to one of these fifteen housing groups, and then the average measures being installed in each housing group are modeled using BEopt to estimate energy savings. For most housing groups, the differences between recommended and installed measure packages is substantial. By comparing actual IHP retrofit measures to BEopt-recommended cost-optimal measures, missed savings opportunities are identified in some housing groups; also, valuable information is obtained regarding housing groups where IHP achieves greater savings than BEopt-modeled, cost-optimal recommendations. Additionally, a measure-level sensitivity analysis conducted for one housing group reveals which measures may be contributing the most to gas and electric savings. Overall, the study finds not only that for some housing groups, the average IHP retrofit results in more energy savings than would result from cost-optimal, BEopt-recommended measure packages, but also that linking home categorization to standardized retrofit measure packages provides an opportunity to streamline the process for single family home energy retrofits and maximize both energy savings and cost-effectiveness.

    Hospital laundries are one of the largest consumers of water and electrical and thermal energy. This paper examined the energy savings achieved by a system using the hot wastewater from the washing process. Hospital laundries consume thermal energy using steam, which is produced in boilers by burning diesel oil or natural gas. Electrical energy for the mechanical drives, ventilation and also the lighting required in the laundry area are big consumers of energy. The paper presented the proposed system and discussed the parameters of the system and system dimensioning. The paper also provided and discussed an interpretation of steam and energy savings. The proposed system was considered to be economically viable, simple in its construction, installation and operation. From the application of the suggested system, the cost savings resulted in a satisfactory payback period for the capital invested of approximately three to five years. 14 refs., 4 tabs., 2 figs.

    This paper discusses the cost savings impact of employing an energy manager with a 16,000-employee corporation. The corporation, Canada's second largest airline, is currently operating nearly 3,000,000 ft 2 of mixed-use facilities spread across the country, with an annual energy budget for ground facilities of over Cdn $4,000,000. This paper outlines the methodology used by the energy manager to deploy an energy management program over a two-year period between April 1995 and May 1997. The paper examines the successes and the lessons learned during the period and summarizes the costs and benefits of the program. The energy manager position was responsible for developing an energy history database with more than 100 active accounts and for monitoring and verifying energy savings. The energy manager implemented many relatively low-cost energy conservation measures, as well as some capital projects, during the first two years of the program. In total, these measures provided energy cost savings of $210,000 per year, or 5% of the total budget. In each case, technologies installed as part of the energy retrofit projects provided not only cost savings but also better control, reduced maintenance, and improved working conditions for employees

  18. Energy Savings from Industrial Water Reductions

    Energy Technology Data Exchange (ETDEWEB)

    Rao, Prakash; McKane, Aimee; de Fontaine, Andre

    2015-08-03

    Although it is widely recognized that reducing freshwater consumption is of critical importance, generating interest in industrial water reduction programs can be hindered for a variety of reasons. These include the low cost of water, greater focus on water use in other sectors such as the agriculture and residential sectors, high levels of unbilled and/or unregulated self-supplied water use in industry, and lack of water metering and tracking capabilities at industrial facilities. However, there are many additional components to the resource savings associated with reducing site water use beyond the water savings alone, such as reductions in energy consumption, greenhouse gas emissions, treatment chemicals, and impact on the local watershed. Understanding and quantifying these additional resource savings can expand the community of businesses, NGOs, government agencies, and researchers with a vested interest in water reduction. This paper will develop a methodology for evaluating the embedded energy consumption associated with water use at an industrial facility. The methodology developed will use available data and references to evaluate the energy consumption associated with water supply and wastewater treatment outside of a facility’s fence line for various water sources. It will also include a framework for evaluating the energy consumption associated with water use within a facility’s fence line. The methodology will develop a more complete picture of the total resource savings associated with water reduction efforts and allow industrial water reduction programs to assess the energy and CO2 savings associated with their efforts.

    The drive towards sustainable, low-energy buildings has increased the need for simple, yet accurate methods to evaluate whether a daylit building meets minimum standards for energy and human comfort performance. Current metrics do not account for the temporal and spatial aspects of daylight, nor of occupants comfort or interventions. This paper reviews the historical basis of current compliance methods for achieving daylit buildings, proposes a technical basis for development of better metrics, and provides two case study examples to stimulate dialogue on how metrics can be applied in a practical, real-world context.

    Purpose of the report is to provide information about the electricity-saving potential of new technologies to OCEP that it can use in developing alternative long-term projections of US electricity consumption. Low-, base-, and high-case scenarios of the electricity savings for ten technologies were prepared. The total projected annual savings for the year 2000 for all ten technologies were 137 billion kilowatt hours (BkWh), 279 BkWh, and 470 BkWh, respectively, for the three cases. The magnitude of these savings projections can be gauged by comparing them to the Department's reference case projection for the 1985 National Energy Policy Plan. In the Department's reference case, total consumption in 2000 is projected to be 3319 BkWh. Thus, the savings projected here represent between 4% and 14% of total consumption projected for 2000. Because approximately 75% of the base-case estimate of savings are already incorporated into the reference forecast, reducing projected electricity consumption from what it otherwise would have been, the savings estimated here should not be directly subtracted from the reference forecast.

    When the quantity of paint used for industrial coating is assumed to be 420,000 tons, it is estimated that the area being coated is 2.8 billion m 2 , the petroleum required for pretreatment steam, drying and baking is 1.68 million tons, and the required amount of energy saving is 120,000 tons per year in terms of petroleum. The authors examined how the adoption of electron beam curing for surface coating contributes to the energy saving. So far, it has been said that electron beam curing is more efficient than thermal or light curing in energy consumption, but the premise condition was not clear. The theoretical energy requirement for thermal curing, light curing and electron beam curing was calculated and compared. The comparison of the measured values was also performed. The amount of energy required for thermal curing, UV light curing and electron beam curing was roughly 100:10:1, and the cost of energy for them was 50:5:1. In spite of the large merit of electron beam curing, it has not spread as expected, because of the repayment cost of the facility and the cost of inert gas required for the process. Energy saving is brought about by electron beam curing, but the overall cost must be examined case by case. (Kako, I.)

    Full Text Available Purpose. Traction calculations with the definition of energy-efficient trajectories provide search for rational energy consumption depending on the time course of the train. When selecting energy-efficient trajectory of the train and the development of regime charts conducting trains must take into account variables such as: the profile of the site, weight train, locomotive series, etc. When increasing the speed of the growth it occurs the resistance movement, which is proportional to the square of the speed, which leads to higher costs of fuel and energy resources. In contrast, the reduction of costs due to the decrease in speed leads to an increase in travel time of the train, which should be consistent with the timetable and other technical and economic parameters, depending on the speed. The article describes one way to reduce the cost of energy for traction. The aim of the article is to reduce energy consumption by identifying energy-saving control modes. It occurs with the locomotive optimization function of control actions on the running time of the train and the flow of energy in the management of the train from the end of the acceleration to go to the coasts. Methodology. The technique of choice of energy saving path of the train and power control and electric locomotives with electric transmission provides the calculation of multiple paths with variable input data and parameters of the composition of the train situation. The methodology takes into account the uniform mathematical methods of search and parametric optimization. For uniformity of motion needed to slow down the accelerating forces are balanced. Findings. On the basis of calculations of multiple advanced algorithms determine the trajectories of energy-saving trains, built multiparametric locomotive power control function, which can reduce energy consumption by 11 to 13% depending on the weight of the train and the train situation.

    Danish households use more than 30% of the total amount of energy being used in Denmark. More than 80% of this energy is dedicated to space heating. The same relation is seen in many OECD countries. The corresponding energy savings potential was recently estimated at 30% of the energy used in buildings. Energy labelling is seen as an important instrument to target these potential energy savings. This paper evaluates the effects of the Danish Energy Labelling Scheme on energy consumption in existing single-family houses with propensity score matching using real metered natural gas consumption and a very wide range of register data describing the houses and households. The study did not find significant energy savings due to the Danish Energy Labelling Scheme, but more research would be needed to complement this conclusion

    The Compressed Air Sector accounts for a mean 10% worldwide electricity consumption, which ensures about its importance, when energy saving and CO 2 emissions reduction are in question. Since the compressors alone account for 15% overall industry electricity consumption, it appears vital to pay attention to machine performances. The paper presents an overview of present compressor technology and focuses on saving directions for screw and sliding vanes machines, according to data provided by the Compressed Air and Gas Institute and PNEUROP. Data were processed to obtain consistency with fixed reference pressures and organized as a function of main operating parameters. Each sub-term, contributing to the overall efficiency (adiabatic, volumetric, mechanical, electric, organic), was considered separately: the analysis showed that the thermodynamic improvement during compression achievable by splitting the compression in two stages, with a lower compression ratio, opens the way to significantly reduce the energy specific consumption. - Highlights: • Compressors technology overview in industrial compressed air systems. • Market compressors efficiency baseline definition. • Energy breakdown and evaluation of main efficiency terms. • Assessment of air cooling-related energy saving potential. • Energy specific consumption reduction through dual stage compression.

    Since the ecological footprint analysis in 1970s suggested changing consumption patterns and overpopulation concerns, energy policy such as energy conservation and use of renewable energy has become of prime importance. Several results of the long-term energy demand and supply analysis in 2050 or 2100 to reduce drastically carbon dioxide emission as a measure against global warming, showed the necessity of nuclear power deployment as well as maximum efforts to save energy, exploitation of the separation and disposal of carbon dioxide, and shifting energy sources to fuels that emit less greenhouse gases or non-fossil fuels. As a promising means to contribute to long-term energy supply, nuclear power generation is expected with improving safety, economic efficiency, environmental adaptability, and nuclear proliferation resistance of the technologies.

    Full Text Available Regulating energy consumption can reduce both greenhouse gas emissions and expenditures. In order to maximize efficiency, appropriate energy protocols for buildings must be devised and implemented. This study examines predicted and real energy savings, the differences between them, and the methods which might reduce these discrepancies. Analyses for 195 high-efficiency apartment units (certified based on the energy efficiency rating system in use in Korea indicated an average difference of 23% between predicted and real energy savings. This was found to be due to the fact that predictions failed to take variables such as Heating Type, Corridor Type, and Climate into account. By accounting for these factors, an appropriate calculation formula may be established. Using the revised calculation formula to reevaluate the predicted energy savings of 13 apartment units resulted in a reduction of 7% in the aforementioned discrepancy between predicted and real energy savings. Using the proposed formula to predict energy savings in buildings could improve accuracy, thus facilitating the setting of appropriate standards for restrictions on greenhouse gas emissions of buildings.

    2012-06-01

    This paper evaluates the issue of non-energy benefits within the context of the U.S. energy services company (ESCO) industry?a growing industry comprised of companies that provide energy savings and other benefits to customers through the use of performance-based contracting. Recent analysis has found that ESCO projects in the public/institutional sector, especially at K-12 schools, are using performance-based contracting, at the behest of the customers, to partially -- but not fully -- offset substantial accumulated deferred maintenance needs (e.g., asbestos removal, wiring) and measures that have very long paybacks (roof replacement). This trend is affecting the traditional economic measures policymakers use to evaluate success on a benefit to cost basis. Moreover, the value of non-energy benefits which can offset some or all of the cost of the non-energy measures -- including operations and maintenance (O&M) savings, avoided capital costs, and tradable pollution emissions allowances-- are not always incorporated into a formal cost-effectiveness analysis of ESCO projects. Nonenergy benefits are clearly important to customers, but state and federal laws that govern the acceptance of these types of benefits for ESCO projects vary widely (i.e., 0-100percent of allowable savings can come from one or more non-energy categories). Clear and consistent guidance on what types of savings are recognized in Energy Savings agreements under performance contracts is necessary, particularly where customers are searching for deep energy efficiency gains in the building sector.

    A web-based Roof Savings Calculator (RSC) has been deployed for the United States Department of Energy as an industry-consensus tool to help building owners, manufacturers, distributors, contractors and researchers easily run complex roof and attic simulations. This tool employs modern web technologies, usability design, and national average defaults as an interface to annual simulations of hour-by-hour, whole-building performance using the world-class simulation tools DOE-2.1E and AtticSim in order to provide estimated annual energy and cost savings. In addition to cool reflective roofs, RSC simulates multiple roof and attic configurations including different roof slopes, above sheathing ventilation, radiant barriers, low-emittance roof surfaces, duct location, duct leakage rates, multiple substrate types, and insulation levels. A base case and energy-efficient alternative can be compared side-by-side to estimate monthly energy. RSC was benchmarked against field data from demonstration homes in Ft. Irwin, California; while cooling savings were similar, heating penalty varied significantly across different simulation engines. RSC results reduce cool roofing cost-effectiveness thus mitigating expected economic incentives for this countermeasure to the urban heat island effect. This paper consolidates comparison of RSC s projected energy savings to other simulation engines including DOE-2.1E, AtticSim, Micropas, and EnergyPlus, and presents preliminary analyses. RSC s algorithms for capturing radiant heat transfer and duct interaction in the attic assembly are considered major contributing factors to increased cooling savings and heating penalties. Comparison to previous simulation-based studies, analysis on the force multiplier of RSC cooling savings and heating penalties, the role of radiative heat exchange in an attic assembly, and changes made for increased accuracy of the duct model are included.

    We teach students between 14 and 18 years old at a high school in Italy. In the first class, one of the topics we treat is related to the atmosphere. The students learn the composition of air, the importance of the natural greenhouse effect in keeping the average temperature of the planet and how human activity is increasing the level of greenhouse gases, enhancing greenhouse effect and causing global warming. It is possible to reach this knowledge using different materials and methods such as schoolbooks, articles, websites or films, individual or group work, but as students gradually become aware of the problem of climate change due to global warming, it is necessary to propose a solution that can be experienced and measured by students. This is the aim of the project "Switch off the light, to switch on the future". The project doesn't need special materials to be carried out but all the people in the community who work and "live" at school should participate in it. The project deals directly with saving electric energy, by changing the habits of the use of electricity. Saving electric energy means saving CO2 emitted to atmosphere, and consequently contributing to the reduction of greenhouse gases emission. Normally, lights in the school are switched on in the early morning and switched off at the end of lessons. Nobody is responsible to turn out the lights in classes, so students choose one or two "Light guardians" who are responsible for the light management. Simple rules for light management are written and distributed in the classes so that the action of saving energy is spread all over the school. One class participates in the daily data collection from the electricity meter, before and after the beginning of the action. At the end of the year the data are treated and presented to the community, verifying if the electric consumption has been cut down or not. This presentation is public, with students who directly introduce collected data, results and

    This paper surveyed the natural gas distribution systems employed in the Italian civil, industrial and thermoelectric sectors to identify those installations which can make use of gas decompression energy recovery systems (consisting of turbo-expanders or alternative expanders) to economically generate electric power. Estimates were then made of the total amount of potential energy savings. The study considered as eligible for energy savings interventions only those plants with a greater than 5,000 standard cubic meter per hour plant capacity. It was evaluated that, with suitable decompression equipment installed at 50 key installations (33 civil, 15 industrial), about 200 GWh of power could be produced annually, representing potential savings of about 22,000 petroleum equivalent tonnes of energy. A comparative analysis was done on three investment alternatives involving inputs of varying amounts of Government financial assistance

    The objective of this study was to develop, monitor, analyze, and report on an integrated resource-conservation program highlighting efficient residential appliances and fixtures. The sites of study were 50 homes in two water-constrained communities located in Oregon. The program was designed to maximize water savings to these communities and to serve as a model for other communities seeking an integrated approach to energy and water resource efficiency. The program included the installation and in-place evaluation of energy- and water-efficient devices including the following: horizontal axis clothes washers (and the matching clothes dryers), resource-efficient dishwashers, an innovative dual flush low-flow toilet, low-flow showerheads, and faucet aerators. The significance of this activity lies in its integrated approach and unique metering evaluation of individual end-use, aggregated residential total use, and system-wide energy and water benefits.

    A set of models are employed to estimate the potential of total energy saved of productions and segmented energy saving for telecom operators in China. During the estimation, the total energy saving is divided into that by technology and management, which are derived from technical reform and progress, and management control measures and even marketing respectively, and the estimating methodologies for energy saving potential of each segment are elaborated. Empirical results from China Mobile indicate that, first, the technical advance in communications technology accounts for the largest proportion (70%–80%) of the total energy saved of productions in telecom sector of China. Second, technical reform brings about 20%–30% of the total energy saving. Third, the proportions of energy saving brought by marketing and control measures appear relatively smaller, just less than 3%. Therefore, China's telecom operators should seize the opportunity of the revolution of communications network techniques in recent years to create an advanced network with lower energy consumption

    Zhu, Yidan

    As hotels' concern about sustainability and budget-control is growing steadily, energy-saving issues have become one of the important management concerns hospitality industry face. By executing proper energy-saving practices, previous scholars believed that hotel operation costs can decrease dramatically. Moreover, they believed that conducting energy-saving practices may eventually help the hotel to gain other benefits such as an improved reputation and stronger competitive advantage. The energy-saving issue also has become a critical management problem for the hotel industry in China. Previous research has not investigated energy-saving in China's hotel segment. To achieve a better understanding of the importance of energy-saving, this document attempts to present some insights into China's energy-saving practices in the tourist accommodations sector. Results of the study show the Chinese general managers' attitudes toward energy-saving issues and the differences among the diverse hotel managers who responded to the study. Study results indicate that in China, most of the hotels' energy bills decrease due to the implementation of energy-saving equipments. General managers of hotels in operation for a shorter period of time are typically responsible for making decisions about energy-saving issues; older hotels are used to choosing corporate level concerning to this issue. Larger Chinese hotels generally have official energy-saving usage training sessions for employees, but smaller Chinese hotels sometimes overlook the importance of employee training. The study also found that for the Chinese hospitality industry, energy-saving practices related to electricity are the most efficient and common way to save energy, but older hotels also should pay attention to other ways of saving energy such as water conservation or heating/cooling system.

    Full Text Available The paper presents the analysis of the dynamics of the heat transfer through the outer wall of the thermal technical spaces, taking into account the impact of the sinusoidal nature of the changes in atmospheric temperature. These temporal variations of the input on the outer surface of the chamber divider result at the output of the sinusoidal change on the inner wall of the room, but suitably suppressed and shifted in phase. Properly selected phase shift is clearly important for saving energy used for the operation associated with the maintenance of a specific regime of heat inside the thermal technical chamber support. Laboratory tests of the model and the actual object allowed for optimal design of the chamber due to the structure of the partition as well as due to the orientation of the geographical location of the chamber.

    More efficient use of energy resources can be promoted by various regulatory means, i.e., taxation, subsidies, and pricing. Various incentives can be provided by income and revenue tax breaks-deductible energy audit fees, energy saving investment credits, breaks for energy saving entrepreneurs, and energy savings accounts run through utility accounts. Value added and excise taxes can also be adjusted to reward energy saving investments and energy saving entrepreneurial activity. Incentives can be provided in the form of cash refunds, including trade-in-and-scrap programs and reimbursements or subsidies on audit costs and liability insurance. Pricing incentives include lower rates for less energy use, prepayment of deposit related to peak load use, electronically dispatched multiple tariffs, savings credits based on prior peak use, and subsidized {open_quotes}leasing{close_quotes} of more efficient appliances and lights. Credits, with an emphasis on pooling small loans, and 5-year energy savings contracts are also discussed.

    Dark roofs raise the summertime air-conditioning demand of buildings. For highly-absorptive roofs, the difference between the surface and ambient air temperatures can be as high as 90 F, while for highly-reflective roofs with similar insulative properties, the difference is only about 20 F. For this reason, cool roofs are effective in reducing cooling energy use. Several experiments on individual residential buildings in California and Florida show that coating roofs white reduces summertime average daily air-conditioning electricity use from 2--63%. This demonstration project was carried out to address some of the practical issues regarding the implementation of reflective roofs in a few commercial buildings. The authors monitored air-conditioning electricity use, roof surface temperature, plenum, indoor, and outdoor air temperatures, and other environmental variables in three buildings in California: two medical office buildings in Gilroy and Davis and a retail store in San Jose. Coating the roofs of these buildings with a reflective coating increased the roof albedo from an average of 0.20--0.60. The roof surface temperature on hot sunny summer afternoons fell from 175 F--120 F after the coating was applied. Summertime average daily air-conditioning electricity use was reduced by 18% (6.3 kWh/1000ft{sup 2}) in the Davis building, 13% (3.6 kWh/1000ft{sup 2}) in the Gilroy building, and 2% (0.4 kWh/1000ft{sup 2}) in the San Jose store. In each building, a kiosk was installed to display information from the project in order to educate and inform the general public about the environmental and energy-saving benefits of cool roofs. They were designed to explain cool-roof coating theory and to display real-time measurements of weather conditions, roof surface temperature, and air-conditioning electricity use. 55 figs., 15 tabs.

    Full Text Available This paper presents an experimental study on the replacement of CFC12 and HFC134a by the new R290/R600a refrigerant mixture as drop-in replacement refrigerant with and without the effect of magnetic field. Without any modification to the system components drop-in experimental tests were performed on a vapour compression refrigeration system with a reciprocating compressor, which was originally designed to operate with CFC12.The test results with no magnets showed that the refrigerant R290/R600a had 19.9-50.1% higher refrigerating capacity than R12 and 28.6-87.2% than R134a. The mixture R290/R600a consumed 6.8- -17.4% more energy than R12. The coefficient of performance of R290/R600a mixture increases from 3.9-25.1% than R12 at lower evaporating temperatures and 11.8-17.6% at higher evaporating temperatures. The effect of magnetic field force reduced the compressor energy consumption by 1.5-2.5% than with no magnets. The coefficient of performance of the system was higher in the range 1.5-2.4% with the effect of magnetic field force. The R290/600a (68/32 by wt.% mixture can be considered as an excellent alternative refrigerant for CFC12 and HFC134a systems.

    Highlights: • Energy saving propagation along a social network is modelled. • This model consists of a time evolving weighted directed network. • Network weights and information decay are applied in savings calculation. - Abstract: It is noted that human behaviour changes can have a significant impact on energy consumption, however, qualitative study on such an impact is still very limited, and it is necessary to develop the corresponding mathematical models to describe how much energy savings can be achieved through human engagement. In this paper a mathematical model of human behavioural dynamic interactions on a social network is derived to calculate energy savings. This model consists of a weighted directed network with time evolving information on each node. Energy savings from the whole network is expressed as mathematical expectation from probability theory. This expected energy savings model includes both direct and indirect energy savings of individuals in the network. The savings model is obtained by network weights and modified by the decay of information. Expected energy savings are calculated for cases where individuals in the social network are treated as a single information source or multiple sources. This model is tested on a social network consisting of 40 people. The results show that the strength of relations between individuals is more important to information diffusion than the number of connections individuals have. The expected energy savings of optimally chosen node can be 25.32% more than randomly chosen nodes at the end of the second month for the case of single information source in the network, and 16.96% more than random nodes for the case of multiple information sources. This illustrates that the model presented in this paper can be used to determine which individuals will have the most influence on the social network, which in turn provides a useful guide to identify targeted customers in energy efficiency technology rollout

    Experiments performed at the University of Missouri-Rolla's Waterjet Laboratory have demonstrated clearly the ability of waterjets to disaggregate, in a single step, four different mineral ores, including ores containing iron, lead and copper products. The study focused mainly on galena-bearing dolomite, a lead ore, and compared the new technology with that of traditional mining and milling to liberate the valuable constituent for the more voluminous host rock. The technical term for the disintegration of the ore to achieve this liberation is comminution. The potential for energy savings if this process can be improved, is immense. Further, if this separation can be made at the mining face, then the potential energy savings include avoidance of transportation (haulage and hoisting) costs to move, process and store this waste at the surface. The waste can, instead, be disposed into the available cavities within the mine. The savings also include the elimination of the comminution, crushing and grinding, stages in the processing plant. Future prototype developments are intended to determine if high-pressure waterjet mining and processing can be optimized to become cheaper than traditional fragmentation by drilling and blasting and to optimize the separation process. The basic new mining process was illustrated in tests on two local rock types, a low-strength sandstone with hematite inclusions, and a medium to high-strength dolomite commonly used for construction materials. Illustrative testing of liberation of minerals, utilized a lead-bearing dolomite, and included a parametric study of the optimal conditions needed to create a size distribution considered best for separation. The target goal was to have 50 percent of the mined material finer than 100 mesh (149 microns). Of the 21 tests that were run, five clearly achieved the target. The samples were obtained as run-of-mine lumps of ore, which exhibited a great deal of heterogeneity within the samples. This

    This Technical Support Document documents the technical analysis and design guidance for large hospitals to achieve whole-building energy savings of at least 50% over ANSI/ASHRAE/IESNA Standard 90.1-2004 and represents a step toward determining how to provide design guidance for aggressive energy savings targets. This report documents the modeling methods used to demonstrate that the design recommendations meet or exceed the 50% goal. EnergyPlus was used to model the predicted energy performance of the baseline and low-energy buildings to verify that 50% energy savings are achievable. Percent energy savings are based on a nominal minimally code-compliant building and whole-building, net site energy use intensity. The report defines architectural-program characteristics for typical large hospitals, thereby defining a prototype model; creates baseline energy models for each climate zone that are elaborations of the prototype models and are minimally compliant with Standard 90.1-2004; creates a list of energy design measures that can be applied to the prototype model to create low-energy models; uses industry feedback to strengthen inputs for baseline energy models and energy design measures; and simulates low-energy models for each climate zone to show that when the energy design measures are applied to the prototype model, 50% energy savings (or more) are achieved.

    Energy saving and renewable energy are again on the Dutch political agenda. Based on the governmental energy report, market parties have developed the action plan for the realisation of national renewable energy targets. The evaluation of recently closed subsidy programmes and development of new incentives take place in close cooperation among governmental organisations and market parties. For the financing of the action plan the government has reserved the budget up to 2011. The government believes that the implementation of energy efficiency and renewable energy will strengthen the national economy and that the benefits of these measures will exceed the costs. The main obstacles related to the implementation of a large scale wind power generation are: spatial integration, permits and connection to the grid. Also, the large scale biomass plants meet problems because of the lack of clear environmental and sustainability criteria. The Dutch targets for 2020 are: increasing of energy efficiency with 20%, 20% renewable energy and decreasing of CO 2 -emissions with 30%.(author)

    The measured energy savings resulting from using night temperature setback in typical light-construction wooden office buildings was determined. Researchers installed monitoring equipment in a six-building sample of two-story wooden buildings at Fort Devens, Massachusetts. Data obtained during both single-setting and night-setback operating modes were used to develop models of each building's heat consumption as a function of the difference between inside and outside temperature. These models were used to estimate seasonal savings that could be obtained from the use of night-setback thermostat control. The measured savings in heating energy from using night temperature setback for the six Fort Devens buildings ranged from 14% to 25%; the mean savings was 19.2%. Based on an energy cost of $0.65/therm of natural gas, the estimated average cost savings of using automatic setback thermostats in these buildings is $780 per year per building

    The conventional approach for energy saving in a process system is to maximize heat recovery without changing any process conditions by using pinch technology. “Self-heat recuperation technology” was developed to achieve further energy saving in the process system by eliminating the necessity for any external heat input, such as firing or imported steam. Advanced Energy Saving and its Applications in Industry introduces the concept of self-heat recuperation and the application of such technology to a wide range of processes from heavy chemical complexes to other processes such as drying and gas separation processes, which require heating and cooling during operation.   Conventional energy saving items in a utility system are applied and implemented based on a single site approach, however, when looking at heavy chemical complexes, it was apparent that the low-grade heat discharged as waste from a refinery could also be used in an adjacent petrochemical plant. There could therefore be a large energy savin...

    The Technical Support Document (TSD) for 50% energy savings in small office buildings documents the analysis and results for a recommended package of energy efficiency measures (EEMs) referred to as the advanced EEMs. These are changes to a building design that will reduce energy usage. The package of advanced EEMs achieves a minimum of 50% energy savings and a construction area weighted average energy savings of 56.6% over the ANSI/ASHRAE/IESNA Standard 90.1-2004 for 16 cities which represent the full range of climate zones in the United States. The 50% goal is for site energy usage reduction. The weighted average is based on data on the building area of construction in the various climate locations. Cost-effectiveness of the EEMs is determined showing an average simple payback of 6.7 years for all 16 climate locations. An alternative set of results is provided which includes a variable air volume HVAC system that achieves at least 50% energy savings in 7 of the 16 climate zones with a construction area weighted average savings of 48.5%. Other packages of EEMs may also achieve 50% energy savings; this report does not consider all alternatives but rather presents at least one way to reach the goal. Design teams using this TSD should follow an integrated design approach and utilize additional analysis to evaluate the specific conditions of a project.

    Full Text Available HVAC Heating Ventilation and Air conditioning is the largest consumer of energy in commercial and industrial buildings. HVAC systems account for an approximated 50 of energy use in buildings. The sources of contamination and odour comes from the growth of bacteria mold and fungus that accumulate and develop on wet surfaces of HVAC coils and drain pans causing respiratory infection cough tight chest and wheezing. Besides the effects on human health Fungal contamination that adheres to the fins of cooling coil of air handling unit AHU cause a significant increase in pressure drop across the coil and decrease in heat exchange efficiency which Leeds to loss of cooling capacity and additional energy use. To prevent the fungal and microorganism growth on the cooling coil and drain pan of HVAC systems many studies conducted but not all these solutions were sufficient to remove microbial organism from the HVAC 100 . The UV-C light options through a process known as UVGI Ultraviolet germicidal irradiation is a technology showed a significant impact to produce clean air and improve indoor air quality 16. UVGI lights produce short wavelength light kills microorganisms including viruses bacteria mold and many other fungi by disrupting their DNA. The effectiveness of UVGI installed inside HVAC systems depends on many factors and the application Methods in HVAC systems. A few studies showed whether the use of UVGI results in energy saving. The objective of this study is to find the effect of fungal growth on the cooling coil surface by using field measurements at actual operating conditions of heat transfer and air flow for a non-irradiated coil in comparison to irradiated coil .Hence evaluate if there would be an enthalpy change at the coil and document the effectiveness of UVGI coil cleaning on restoring cooling capacity and save energy.

    Full Text Available Shifting the threshold zone of road tunnels with semitransparent tension structures has shown itself to be an effective way of saving energy in regards to electricity consumption, maintenance, and construction materials used in the electrical lighting, thus lessening negative environmental impacts. Even though the shape of the tension structure has a major influence on energy savings, the optimal type of structure for each tunnel is often difficult to determine, because experiments using real tunnels are extremely expensive. It is thus necessary to find methods of doing this that are both reliable as well as economical. In this research study, three candidate structures were set up at the portal of a scale model of a real tunnel. The energy savings in each case were analyzed and compared. As a result, it was possible to formulate a new equation that calculates the energy savings in the threshold zone.

    Audit predictions of energy-conservation savings are usually much higher than the savings actually achieved. Speculation about possible causes for this discrepancy has often centered around residents' lifestyle, specifically their indoor temperature management. Detailed indoor temperature data and extensive demographic information were available for 300 homes in Hood River, Oregon. These data were analyzed to examine the effect of demographic variables on indoor temperature and energy use. Changes in indoor temperature before and after retrofit were also examined. The effects of these variables were very small. Some small improvements to auditing procedures can be suggested based on this analysis. However, the major conclusion is that while some takeback of energy savings is occurring, it is very small in magnitude and cannot explain the large differences between predicted and achieved energy savings. 8 refs., 19 figs., 5 tabs.

    Webber, Carrie A.; Brown, Richard E.

    1998-01-01

    In 1993 the U.S. Environmental Protection Agency (EPA) introduced ENERGY STAR (registered trademark), a voluntary labeling program designed to identify and promote energy-efficient products. Since then EPA, now in partnership with the U.S. Department of Energy (DOE), has introduced programs for more than twenty products, spanning office equipment, residential heating and cooling equipment, new homes, commercial and residential lighting, home electronics, and major appliances. We present potential energy, dollar and carbon savings forecasts for these programs for the period 1998 to 2010. Our target market penetration case represents our best estimate of future ENERGY STAR savings. It is based on realistic market penetration goals for each of the products. We also provide results under the assumption of 100% market penetration; that is, we assume that all purchasers buy ENERGY STAR-compliant products instead of standard efficiency products throughout the analysis period. Finally, we assess the sensitivity of our target penetration case forecasts to greater or lesser marketing success by EPA and DOE, lower-than-expected future energy prices, and higher or lower rates of carbon emission by electricity generators. The potential savings of ENERGY STAR are substantial. If all purchasers chose Energy Star-compliant products instead of standard efficiency products over the next 15 years, they would save more than$100 billion on their energy bills during those 15 years. (Bill savings are in 1995 dollars, discounted at a 4% real discount rate.)

The result shows that the potential of fuel reduction can be much higher than the solar gain of the solar thermal...... system. For some conditions the fuel reduction can be up to the double of the solar gain due to a strong increase of the system efficiency.

    Financial pressure and concern for the environment has meant many consumers are aware of the need to reduce their consumption of many resources, including energy, which is the focus of the present study. While potential energy use deterrents in the form of access constraints and price increases are forms of extrinsic control, it is not clear how effective these are at reducing consumption and, indeed, it is not clear if such measures are consistent with people's underlying energy saving motivations. Beyond behavioural motivations, people's desires to reduce energy can be thwarted (barriers) and/or supported by a variety of factors, some within their control, while others are perhaps less so. Using a practice-based framework and a qualitative focus group approach, this study presents an exploratory study of these issues. Policy suggestions for overcoming barriers, as well suggestions as to how energy saving behaviours can be supported are offered. - Highlights: • We obtained consumers views about energy saving motivations, barriers and support. • Attitudes towards energy saving are not sufficient to change behaviours. • A practice-based approach to understanding energy saving behaviours is applied. • A practice-based energy-cultures framework (PBECF) is developed. • Barriers and support factors are identified that can be conceptualised within a PBECF

    The findings of this study indicate that potential exists in non-building applications to save energy and costs. This potential could save billions of federal dollars, reduce reliance on fossil fuels, increase energy independence and security, and reduce greenhouse gas emissions. The Federal Government has nearly twenty years of experience with achieving similar energy cost reductions, and letting the energy costs savings pay for themselves, by applying energy savings performance contracts (ESPC) inits buildings. Currently, the application of ESPCs is limited by statute to federal buildings. This study indicates that ESPCs can be a compatible and effective contracting tool for achieving savings in non-building applications.

    Collecting webpage messages can serve as a sensor for investigating the energy-saving potential of buildings. Focusing on stores, a cloud sensor system is developed to collect data and determine their energy-saving potential. The owner of a store under investigation must register online, report the store address, area, and the customer ID number on the electric meter. The cloud sensor system automatically surveys the energy usage records by connecting to the power company website and calculating the energy use index (EUI) of the store. Other data includes the chain store check, company capital, location price, and the influence of weather conditions on the store; even the exposure frequency of store under investigation may impact the energy usage collected online. After collecting data from numerous stores, a multi-dimensional data array is constructed to determine energy-saving potential by identifying stores with similarity conditions. Similarity conditions refer to analyzed results that indicate that two stores have similar capital, business scale, weather conditions, and exposure frequency on web. Calculating the EUI difference or pure technical efficiency of stores, the energy-saving potential is determined. In this study, a real case study is performed. An 8-dimensional (8D) data array is constructed by surveying web data related to 67 stores. Then, this study investigated the savings potential of the 33 stores, using a site visit, and employed the cloud sensor system to determine the saving potential. The case study results show good agreement between the data obtained by the site visit and the cloud investigation, with errors within 4.17%. Among 33 the samples, eight stores have low saving potentials of less than 5%. The developed sensor on the cloud successfully identifies them as having low saving potential and avoids wasting money on the site visit. PMID:24561405

Other data includes the chain store check, company capital, location price, and the influence of weather conditions on the store; even the exposure frequency of store under investigation may impact the energy usage collected online. After collecting data from numerous stores, a multi-dimensional data array is constructed to determine energy-saving potential by identifying stores with similarity conditions. Similarity conditions refer to analyzed results that indicate that two stores have similar capital, business scale, weather conditions, and exposure frequency on web. Calculating the EUI difference or pure technical efficiency of stores, the energy-saving potential is determined. In this study, a real case study is performed. An 8-dimensional (8D) data array is constructed by surveying web data related to 67 stores. Then, this study investigated the savings potential of the 33 stores, using a site visit, and employed the cloud sensor system to determine the saving potential. The case study results show good agreement between the data obtained by the site visit and the cloud investigation, with errors within 4.17%. Among 33 the samples, eight stores have low saving potentials of less than 5%. The developed sensor on the cloud successfully identifies them as having low saving potential and avoids wasting money on the site visit.

    This paper presents some insights into Jordan's energy consumption in the tourist accommodation sector. The results of a recent survey on environmental performance in the tourist accommodation sector in Jordan were used to evaluate energy conservation in hotels. A survey was designed and distributed to hotels' managers and departments' supervisors in order to understand the environmental performance in the tourist accommodation sector in Jordan during the period 10-17 August 2006. Also some field visits were conducted to fully understand hotels interaction regarding the environment, in addition to help interpreting the results of the survey. The study is limited to all classified hotels in Jordan. It was found that lighting hotels' main building and outside areas, and air conditioning consume more electricity compared to other departments. The results show that few classified hotels already installed energy saving equipments, though, it was noticed that managers of one star hotels were not really willing to make such changes in their hotels, on the other hand, other classified hotels (2-5 star hotels) have shown a high willingness to make changes in their hotels to reduce the consumption of different types of energy. Hotel's classification played a significant role in explaining variations in most of the results, particularly when it comes to long-term investments to reduce energy consumption by using energy efficient appliances. Five and four star hotels were the most hotels willing to use energy efficient appliances to reduce energy consumption. The study suggested some strategies to help reduce the negative impacts of high energy consumption in hotels. These strategies include better insulation, and enhanced insulation for the hot water reticulation system. Moreover, enhancing and increasing the level of awareness among all hoteliers through a directed and well-designed campaign. Also offer interest free loans; and activate precise standards and specifications

    Full Text Available The lighting system provides many options for cost-effective energy saving with low or no inconvenience. Lighting improvements are excellent investments in most public buildings, it is usually cost-effective to address because lighting improvements are often easier to make than many process upgrades.For public buildings, the easy no and low cost options to help save money and improve the energy performance are:Understand energy use.Identify optionsPrioritize actionsMake the changes and measure the savings.Continue managing energy efficiency.The challenge is to retrofit traditional lamps with LED lamps of good quality. The benefits of LED light bulbs are long-lasting, durable, cool, mercury free, more efficient, and cost effective.The light Emitting Diode (LED bulb uses a semiconductor as its light source, and is currently one of the most energy efficient and quickly developing types of bulbs for lighting. LEDs increasingly are being purchased to replace traditional bulbs. LEDs are relatively more expensive than other types of bulbs, but are very cost-effective because they use only a fraction of electricity of traditional lighting methods nd can last for longer.Benchmarking guides decision makers to policies aimed at the energy sector through better understanding of energy consumption trends nationwide, e.g.: energy price, moderating, peak demand, and encouraging sectors, low energy expansions.The “Improving Energy Efficiency Project of Lighting and Appliances” carried out energy audits and implemented opportunities of energy saving in lighting for different type of public buildings.To rationalize the use of energy by giving guidelines to consumers, the IEEL&A project prepared some brochures.This paper leads with the results of case studies as energy audits, opportunities in lighting systems, energy saving and CO2 reduction.

  2. Evaluation of methods used to determine realized energy savings

    Boonekamp, Piet G.M.

    2006-01-01

    Most methods to determine realized total energy savings at national or sectoral level make choices, or neglect problems, which hamper the calculation of sound and useful energy-saving figures. Issues are the choice of the right aggregation level, the appropriate variables to construct a reference energy consumption trend, the energy quantities to be applied and interaction between various effects. Uncertainty margins for results lack in most presentations as well. This paper presents six methods, illustrates the adverse effects of certain choices and problems, and investigates how these methods deal with them. The methods are scored with respect to the issues mentioned above. Finally, a number of improvements are suggested, among which the use of final energy demand expressed in primary energy units, and bottom-up analyses at the level of real saving options. The last option is the more important, as it could provide top-down evaluation results (total savings from decomposition) as well as bottom-up policy monitoring results, both being crucial to new European energy-saving policy

    Dattathreya, Macam S.

    Fuel energy is a basic necessity for this planet and the modern technology to perform many activities on earth. On the other hand, quadrupled automotive vehicle usage by the commercial industry and military has increased fuel consumption. Military readiness of Army ground vehicles is very important for a country to protect its people and resources. Fuel energy is a major requirement for Army ground vehicles. According to a report, a department of defense has spent nearly $13.6 billion on fuel and electricity to conduct ground missions. On the contrary, energy availability on this plant is slowly decreasing. Therefore, saving energy in Army ground vehicles is very important. Army ground vehicles are embedded with numerous electronic systems to conduct missions such as silent and normal stationary surveillance missions. Increasing electrical energy consumption of these systems is influencing higher fuel consumption of the vehicle. To save energy, the vehicles can use any of the existing techniques, but they require complex, expensive, and time consuming implementations. Therefore, cheaper and simpler approaches are required. In addition, the solutions have to save energy according to mission needs and also overcome size and weight constraints of the vehicle. Existing research in the current literature do not have any mission aware approaches to save energy. This dissertation research proposes mission aware online energy saving strategies for stationary Army ground vehicles to save energy as well as to meet the electrical needs of the vehicle during surveillance missions. The research also proposes theoretical models of surveillance missions, fuzzy logic models of engine and alternator efficiency data, and fuzzy logic algorithms. Based on these models, two energy saving strategies are proposed for silent and normal surveillance type of missions. During silent mission, the engine is on and batteries power the systems. During normal surveillance mission, the engine is

    Energy savings for a number of new solar heating systems in one family houses have been determined by means of information on the energy consumption of the houses before and after installation of the solar heating systems. The investigated solar heating systems are marketed by Velux Danmark A/S, Sonnnenkraft Scandinavia A/S and Batec Solvarme A/S. Solar domestic hot water systems as well as solar combi systems are included in the investigations The houses have different auxiliary energy supply systems: Natural gas boilers, oil fired burners, electrical heating and district heating. Some of the houses have a second auxiliary energy supply system. The collector areas vary from 1.83 m{sup 2} to 9.28 m{sup 2}. Some of the solar heating systems are based on energy units with a new integrated natural gas boiler and a heat storage for the solar heating system. The existing energy systems in the houses are for most of the houses used as the auxiliary energy systems for the solar heating systems. The yearly energy savings for the houses where the only change is the installation of the solar heating system vary from 300 kWh per m{sup 2} solar collector to 1300 kWh per m{sup 2} solar collector. The average yearly energy savings is about 670 kWh per m{sup 2} solar collector for these solar heating systems. The energy savings per m{sup 2} solar collector are not influenced by the solar heating system type, the company marketing the system, the auxiliary energy supply system, the collector area, the collector tilt, the collector azimuth, the energy consumption of the house or the location of the house. The yearly energy savings for the houses with solar heating systems based on energy units including a new natural gas boiler vary from 790 kWh per m{sup 2} solar collector to 2090 kWh per m{sup 2} solar collector. The average yearly energy savings is about 1520 kWh per m{sup 2} solar collector for these solar heating systems. The energy savings per m{sup 2} solar collector for

    Several countries are considering extending Daylight Saving Time (DST) in order to conserve energy, and the U.S. will extend DST by one month beginning in 2007. However, projections that these extensions will reduce electricity consumption rely on extrapolations and simulations rather than empirical evidence. This paper, in contrast, examines a quasiexperiment in which parts of Australia extended DST in 2000 to facilitate the Sydney Olympics. Using detailed panel data and a triple differences specification, we show that the extension did not conserve electricity, and that a prominent simulation model overstates electricity savings when it is applied to Australia.

    In October 2005, U.S. Department of Energy Secretary Bodman launched his Easy Ways to Save Energy campaign with a promise to provide energy assessments to 200 of the largest U.S. manufacturing plants. DOE's Industrial Technologies Program (ITP) responded to the Secretary's campaign with its Save Energy Now initiative, featuring a new and highly cost-effective form of energy savings assessment. The approach for these assessments drew heavily on the existing resources of ITP's technology delivery component. Over the years, ITP Technology Delivery has worked with industry partners to assemble a suite of respected software tools, proven assessment protocols, training curricula, certified energy experts, and strong partnerships for deployment. The Save Energy Now assessments conducted in calendar year 2006 focused on natural gas savings and targeted many of the nation's largest manufacturing plants - those that consume at least 1 TBtu of energy annually. The 2006 Save Energy Now assessments focused primarily on assessments of steam and process heating systems, which account for an estimated 74% of all natural gas use by U.S. manufacturing plants. Because of the success of the Save Energy Now assessments conducted in 2006 and 2007, the program was expanded and enhanced in two major ways in 2008: (1) a new goal was set to perform at least 260 assessments; and (2) the assessment focus was expanded to include pumping, compressed air, and fan systems in addition to steam and process heating. DOE ITP also has developed software tools to assess energy efficiency improvement opportunities in pumping, compressed air, and fan systems. The Save Energy Now assessments integrate a strong training component designed to teach industrial plant personnel how to use DOE's opportunity assessment software tools. This approach has the advantages of promoting strong buy-in of plant personnel for the assessment and its outcomes and preparing them better to

    Highlights: • Various strategies for HVAC energy saving are described and reviewed. • The influence of each strategy on the HVAC energy saving is investigated. • Combination of existing air conditioning technologies appears to be effective for the energy conservation and comfort. • A comparison study between these approaches is carried out. • Changing the HVAC configuration has the potential to increase or reduce energy savings, depending on several factors. - Abstract: Decreasing the energy consumption of heating, ventilation and air conditioning (HVAC) systems is becoming increasingly important due to rising cost of fossil fuels and environmental concerns. Therefore, finding novel ways to reduce energy consumption in buildings without compromising comfort and indoor air quality is an ongoing research challenge. One proven way of achieving energy efficiency in HVAC systems is to design systems that use novel configurations of existing system components. Each HVAC discipline has specific design requirements and each presents opportunities for energy savings. Energy efficient HVAC systems can be created by re-configuring traditional systems to make more strategic use of existing system parts. Recent research has demonstrated that a combination of existing air conditioning technologies can offer effective solutions for energy conservation and thermal comfort. This paper investigates and reviews the different technologies and approaches, and demonstrates their ability to improve the performance of HVAC systems in order to reduce energy consumption. For each strategy, a brief description is first presented and then by reviewing the previous studies, the influence of that method on the HVAC energy saving is investigated. Finally, a comparison study between these approaches is carried out

    Full Text Available In this study, an energy efficiency studies have been carried out in a natural gas-fired rolling mill annealing furnace of an industrial establishment. In this context, exhaust gas from the furnace has been examined in terms of waste heat potential. In the examinations that have been made in detail; waste heat potential was found as 3.630,31 kW. Technical and feasibility studies have been carried out to realize electricity production through an Organic Rankine Cycle (ORC system for evaluating the waste heat potential of the annealing furnace. It has been calculated that 1.626.378,88 kWh/year of electricity can be generated by using the exhaust gas waste heat of the annealing furnace through an ORC system to produce electric energy with a net efficiency of 16%. The financial value of this energy was determined as 436.032,18 TL/year and the simple repayment period of the investment was 8,12 years. Since the annealing period of the annealing furnace is 2800 hours/year, the investment has not been found to be feasible in terms of the feasibility studies. However, the investment suitability can be assured when the annealing furnace is operating at full capacity for 8,000 hours or more annually.

  19. Making the results of bottom-up energy savings comparable

    Directory of Open Access Journals (Sweden)

    Moser Simon

    2012-01-01

    Full Text Available The Energy Service Directive (ESD has pushed forward the issue of energy savings calculations without clarifying the methodological basis. Savings achieved in the Member States are calculated with rather non-transparent and hardly comparable Bottom-up (BU methods. This paper develops the idea of parallel evaluation tracks separating the Member States’ issue of ESD verification and comparable savings calculations. Comparability is ensured by developing a standardised BU calculation kernel for different energy efficiency improvement (EEI actions which simultaneously depicts the different calculation options in a structured way (e.g. baseline definition, system boundaries, double counting. Due to the heterogeneity of BU calculations the approach requires a central database where Member States feed in input data on BU actions according to a predefined structure. The paper demonstrates the proposed approach including a concrete example of application.

    Expanding on previous research by PARR, this study compares measure packages installed during 800 Illinois Home Performance with ENERGY STAR® (IHP) residential retrofits to those recommended as cost-optimal by Building Energy Optimization (BEopt) modeling software. In previous research, cost-optimal measure packages were identified for 15 Chicagoland single family housing archetypes, called housing groups. In the present study, 800 IHP homes are first matched to one of these 15 housing groups, and then the average measures being installed in each housing group are modeled using BEopt to estimate energy savings. For most housing groups, the differences between recommended and installed measure packages is substantial. By comparing actual IHP retrofit measures to BEopt-recommended cost-optimal measures, missed savings opportunities are identified in some housing groups; also, valuable information is obtained regarding housing groups where IHP achieves greater savings than BEopt-modeled, cost-optimal recommendations.

    In lighting chains, it is not possible to exchange energy saving lamps for light bulbs (market gardening). In the shop sector, however, there will be a number of useful purposes for them (important: long life). Energy-saving lamps function like fluorescent lamps. They can be exchanged for ordinary bulbs because they have the same screw-in system. Economy lamps and fluorescent tubes use approximately 75% less electricity than comparable bulbs, and at the same time, they last about five times as long. What sort of lamp is used should be carefully considered according to what it is to be used for. (orig.).

    2015-06-01

    Full Text Available Dynamic daylight simulations are very useful instruments in daylighting design process. They allow an in depth analysis of indoor daylight availability levels and define if they are adequate to perform a particular visual task. Their results can be used to design shading devices or lighting control systems and compare different technical solutions. The use of these simulations is likely to spread in the common design practice since some regulations and green building rating systems suggest their use. This paper presents dynamic daylight simulation results related to an open-plan office, performed with Autodesk 3ds Max Design®, which is a calculation software validated by recent researches. It is not used in academic context but it is very widespread between technicians for photorenderings production purposes. The goal of this research is to demonstrate the functionality of this software also in dynamic daylight simulations field and propose an analysis' methodology to use it.

    2010-01-01

    Rising concern about energy resource availability and energy prices in Jordan, cost of energy has become an issue that cannot be ignored in Jordan's industrial sector. In this study, energy auditing in a meat production factory related to poultry company was carried out. Based on the collected data and the conservation laws of energy, the performance of steam boilers, domestic hot water boilers, compressors, refrigeration systems, chillers, pumps, daily consumption of diesel and water were reviewed. The percentage of energy consumed by the refrigeration units, with respect to the total energy consumed, has been estimated. The results demonstrated a normal operation with thermal efficiency of 80.66% for the steam boiler, ability to save 18818.99 JD by installing economizer with payback period of 0.637 year and a 12.3% reduction of the energy cost achieved by reducing the blow down rate. The rate of diesel consumption was reduced by 12.87% over the last period of the study as a result of the recommendations that have been submitted to the technicians and professionals. The sum of 22223.77 JD can be saved by using heavy fuel oil instead of diesel oil. Moreover, this study demonstrated that energy saving can be considered as an ideal choice to increase profit and promote competition within the poultry industry if the company adopts all the proposals and recommendations that have been offered by this study.

  10. Energy Savings Assessment for Digital-to-Analog Converter Boxes

    Cheung, Hoi Ying Iris; Meier, Alan; Brown, Richard

    2011-01-18

    The Digital Television (DTV) Converter Box Coupon Program was administered by the U.S. government to subsidize purchases of digital-to-analog converter boxes, with up to two $40 coupons for each eligible household. In order to qualify as Coupon Eligible Converter Boxes (CECBs), these devices had to meet a number of minimum performance specifications, including energy efficiency standards. The Energy Star Program also established voluntary energy efficiency specifications that are more stringent than the CECB requirements. In this study, we measured the power and energy consumptions for a sample of 12 CECBs (including 6 Energy Star labeled models) in-use in homes and estimated aggregate energy savings produced by the energy efficiency policies. Based on the 35 million coupons redeemed through the end of the program, our analysis indicates that between 2500 and 3700 GWh per year are saved as a result of the energy efficiency policies implemented on digital-to-analog converter boxes. The energy savings generated are equivalent to the annual electricity use of 280,000 average US homes.

    Since 1974, EDF is placed between a communication scheme imposed for energy savings and an industrial strategy of massive investment in nuclear power. In ten years, the company managed to increase households electricity consumption without advertising, due in particular to electric heating. But strong tensions were generated by this situation and led the company to develop an institutional communication to the employees and to the general public

  12. Sustainable roofs with real energy savings

    Energy Technology Data Exchange (ETDEWEB)

    Christian, J.E.; Petrie, T.W.

    1996-12-31

    This paper addresses the general concept of sustainability and relates it to the building owner`s selection of a low-slope roof. It offers a list of performance features of sustainable roofs. Experiences and data relevant to these features for four unique roofs are then presented which include: self-drying systems, low total equivalent warming foam insulation, roof coatings and green roofs. The paper concludes with a list of sustainable roofing features worth considering for a low-slope roof investment. Building owners and community developers are showing more interest in investing in sustainability. The potential exists to design, construct, and maintain roofs that last twice as long and reduce the building space heating and cooling energy loads resulting from the roof by 50% (based on the current predominant design of a 10-year life and a single layer of 1 to 2 in. (2.5 to 5.1 cm) of insulation). The opportunity to provide better low-slope roofs and sell more roof maintenance service is escalating. The general trend of outsourcing services could lead to roofing companies` owning the roofs they install while the traditional building owner owns the rest of the building. Such a situation would have a very desirable potential to internalize the costs of poor roof maintenance practices and high roof waste disposal costs, and to offer a profit for installing roofs that are more sustainable. 14 refs., 12 figs.

    2010-01-01

    The increasing demand for mobile broadband is pushing existing 3G networks closer to their capacity limit. Additional carriers together with new HSPA features (HSPA+) are expected to provide the next necessary boost in network capacity. One specific feature in HSPA+ is referred to as Dual...... consumption. This paper proposes an energy saving feature that exploits variations in network traffic. Based on the individual load of each sector, the feature determines if the secondary carrier is detrimental for reaching some pre-set minimum requirements. Each sector is allowed to switch off one...... of their two carriers, during periods of low network traffic. It is concluded that an energy saving ranging between 14% and 36% is possible. This saving comes without degradation of network performance....

    1986-09-01

    Purpose of the report is to provide information about the electricity-saving potential of new technologies to OCEP that it can use in developing alternative long-term projections of US electricity consumption. Low-, base-, and high-case scenarios of the electricity savings for 10 technologies were prepared. The total projected annual savings for the year 2000 for all 10 technologies were 137 billion kilowatt hours (BkWh), 279 BkWh, and 470 BkWh, respectively, for the three cases. The magnitude of these savings projections can be gauged by comparing them to the Department's reference case projection for the 1985 National Energy Policy Plan. In the Department's reference case, total consumption in 2000 is projected to be 3319 BkWh. Because approximately 75% of the base-case estimate of savings are already incorporated into the reference projection, only 25% of the savings estimated here should be subtracted from the reference projection for analysis purposes.

    This paper presents an energy saving approach to the problem of order picking in warehousing environment, which is directly related to the well-known Traveling Salesman Problem (TSP). While the available heuristic algorithms for the order-picking problem search for the route that minimizes the travel time, here the problem is addressed from the energy saving point of view. In a few words, the least energy-consuming route is identified in order to quantify the trade off in time and energy between the fastest route and the most energy economic one. Keeping in mind that often energy is as important as time, especially during a low-demand period, the current paper sheds some light into a two dimensional way of addressing the warehouse material handling problem, which saves time as well as energy. A very interesting finding is that a relatively small loss of service time in many cases may lead to a significant decrease of consumed energy without any additional cost. (author)

  17. Food and drink processing: Introducing energy saving opportunities for business

    2006-04-15

    The food and drink processing industry is the fourth highest industrial energy user in the UK. In 2000, it consumed nearly 70TWh (enough energy to power one million homes for nearly 15 years) and emitted around 13 million tonnes of carbon dioxide into the atmosphere. Energy consumption in the sector could be considerably reduced by implementing simple and effective energy saving measures, reducing carbon emissions and cutting the costs for businesses. This publication is aimed at managers in the industry working in all sub-sectors. Focusing on the low and no-cost measures and actions which will have the quickest payback, this overview demonstrates the best energy saving opportunities in the sector. The industry is very diverse with many sub-sectors. Each sub-sector employs a range of industrial processes. This guide concentrates on technologies and management techniques that offer the greatest potential for energy saving and that are common to the widest range of sub-sectors. These are: Refrigeration; Process measurement and control; Compressed air; Motors and drives; Boilers and heat distribution; Cooking; Distillation, drying and evaporation; Energy management. The relative importance of each area will also depend on the sub-sector. For example, refrigeration cost will make up a large proportion of energy bills in the frozen and chilled foods sub-sector. Equally, for a business that produces confectionery, boilers and heat distribution systems will make the largest contribution. (GB)

    The overall objective of this study is to analyse the effects of using EU ETS auction revenues to stimulate investments in energy savings in three key target sectors, i.e. Households, Tertiary and Industry (including both ETS and non-ETS industrial installations). The scenarios used refer basically to the situation before the recent agreement on the Energy Efficiency Directive (EED) and include (a mixture of) different policy options to enhance energy savings in the target sectors, in particular (1) reducing the ETS cap, (2) introducing an Energy Efficiency Obligation (EEO) for energy suppliers or distributors, and/or (3) using ETS auction revenues to support additional (private) investments in raising energy efficiency. In order to meet this objective a variety of different policy scenarios have been defined and analysed by means of the 'Energy-Environment-Economy Model for Europe (E3ME)'. The study presents and discusses a large variety of scenario modelling results by the year 2020 at the EU27 level. These results refer to, among others, energy savings, GHG emissions, the ETS carbon price, household electricity bills and to changes in some macro- or socio-economic outcomes such as GDP, inflation, employment or international trade. Finally, the study discusses some policy findings and implications, including options to enhance the effectiveness of some EE policies, in particular those having a potential adverse effect on the ETS carbon price.

  19. Energy savings potential from improved building controls for the US commercial building sector

    2017-09-27

    The U.S. Department of Energy’s (DOE’s) Building Technologies Office (BTO) sponsored a study to determine the potential national savings achievable in the commercial building sector through widespread deployment of best practice controls, elimination of system and component faults, and use of better sensing. Detailed characterization of potential savings was one source of input to set research, development, and deployment (RD&D) goals in the field of building sensors and controls. DOE’s building energy simulation software, EnergyPlus, was employed to estimate the potential savings from 34 measures in 9 building types and across 16 climates representing almost 57% of commercial building sector energy consumption. In addition to estimating savings from individual measures, three packages of measures were created to estimate savings from the packages. These packages represented an 1) efficient building, 2) typical building, and 3) inefficient building. To scale the results from individual measures or a package to the national scale, building weights by building type and climate locations from the Energy Information Administration’s 2012 Commercial Building Energy Consumption Survey (CBECS) were used. The results showed significant potential for energy savings across all building types and climates. The total site potential savings from individual measures by building type and climate location ranged between 0% and 25%. The total site potential savings by building type aggregated across all climates (using the CBECS building weights) for each measure varied between 0% and 16%. The total site potential savings aggregated across all building types and climates for each measure varied between 0% and 11%. Some individual measures had negative savings because correcting underlying operational problems (e.g., inadequate ventilation) resulted in increased energy consumption. When combined into packages, the overall national savings potential is estimated to be 29

    2007-01-01

    Energy saving work, understood as lowering the supply voltage when load torque is much less than rated, is one way of reducing power losses in an induction cage machine working with a variable load. Reduction in power losses also affects the thermal properties of an induction machine because the energy saving work allows the temperature rise of the windings to decrease. Thanks to a lower temperature of the windings, the same load torque can be carried by a machine of less rated power. The ability of energy saving work to reduce the temperature of windings depends on the thermal properties of an induction machine, which are different in the case of a machine with foreign ventilation and its own ventilation. This paper deals with the thermal effect of energy saving work on a frequency controlled induction cage machine. A comparison of the properties of a machine with its own and outside ventilation is presented. The results of the investigations are shown for a 3 kW induction cage machine with the two previously mentioned ways of ventilation: one provided with a fan placed on a shaft and the other provided with a fan driven by an auxiliary motor

    Freni, Gabriele; Sambito, Mariacrocetta

    2017-11-01

    The present paper describes different energy production, recovery and saving measures which can be applied in an integrated urban water system. Production measures are often based on the installation of photovoltaic systems; the recovery measures are commonly based on hydraulic turbines, exploiting the available pressure potential to produce energy; saving measures are based on substitution of old pumps with higher efficiency ones. The possibility of substituting some of the pipes of the water supply system can be also considered in a recovery scenario in order to reduce leakages and recovery part of the energy needed for water transport and treatment. The reduction of water losses can be obtained through the Active Leakage Control (ALC) strategies resulting in a reduction in energy consumption and in environmental impact. Measures were applied to a real case study to tested it the efficiency, i.e., the integrated urban water system of the Palermo metropolitan area in Sicily (Italy).

This is possible to obtainment in significant quantities in fields in which use up the large quantities of energy. The formation the microclimate of interiors is an example of such situation. Especially in the case air conditioning, heating and mechanical ventilation. There is, however, a possibility of energy saving as well as considerable reducing the pollution coming from combustion of raw materials by utilising the natural renewable energy from the shallow ground. In the paper the results gained during several year of continuous measurement on the exchanger were presented. In summer periods an air cooling occurs 10–12 K, e. g. from +30 °C to +20 °C. In winter on the other hand, a preparatory preheating of the air is possible, e.g. from-18°C to about ± 0°C. It is then possible to obtain for the air conditioning system the total energy needed for cooling purposes at the summer periods, or up to 50% of the ventilation heat energy in winter picks.

    Full Text Available An artificial intelligent technique has been implemented in this research using real time datas to calculate how much energy can be chopped from peak load demand. The results are based on real time data that are taken from power delivering centers. These datas do reflect the present condition of power and a solution to those critical conditions during the peak period. These are done in such a way such that helps in judicious scheduling of load. The time based load scheduling has been done so as to understand the basic criteria for solving power crisis during morning peak and early evening peak. The sunray availability and percentage of load that will use day light saving (DLS technique has been taken into account in this work. The results shows that about 0.5% to 1% of load can be shedded off from the peak load period which otherwise is reduction of power. Thus it otherwise also means that an equivalent amount of energy is saved which amounts to a large saving of national money. This result is obtained on monthly and even daily basis. Thus this paper justifies DLS gives a new renewable technique to save energy.

  14. Heat Saving Strategies in Sustainable Smart Energy Systems

    2014-06-01

    Full Text Available This paper investigates to which extent heat should be saved rather than produced and to which extent district heating infrastructures, rather than individual heating solutions, should be used in future sustainable smart energy systems. Based on a concrete proposal to implement the Danish governmental 2050 fossil-free vision, this paper identifies marginal heat production costs and compares these to marginal heat savings costs for two different levels of district heating. A suitable least-cost heating strategy seems to be to invest in an approximately 50% decrease in net heat demands in new buildings and buildings that are being renovated anyway, while the implementation of heat savings in buildings that are not being renovated hardly pays. Moreover, the analysis points in the direction that a least-cost strategy will be to provide approximately 2/3 of the heat demand from district heating and the rest from individual heat pumps.

    Full Text Available Dumps of a mining-metallurgical complex of post-Soviet Republics have accumulated a huge amount of technogenic waste products. Out of them, Kazakhstan alone has preserved about 20 billion tons. In the field of technogenic waste treatment, there is still no technical solution that leads it to be a profitable process. Recent global trends prompted scientists to focus on developing energy-saving and a highly efficient melting unit that can significantly reduce specific fuel consumption. This paper reports, the development of a new technological method-smelt layer of inversion phase. The introducing method is characterized by a combination of ideal stirring and ideal displacement regimes. Using the method of affine modelling, recalculation of pilot plant's test results on industrial sample has been obtained. Experiments show that in comparison with bubbling and boiling layers of smelt, the degree of zinc recovery increases in the layer of inversion phase. That indicates the reduction of the possibility of new formation of zinc silicates and ferrites from recombined molecules of ZnO, SiO2, and Fe2O3. Calculations show that in industrial samples of the pilot plant, the consumption of natural gas has reduced approximately by two times in comparison with fuming-furnace. The specific fuel consumption has reduced by approximately four times in comparison with Waelz-kiln.

    2009-11-11

    This Inventions and Innovations program supported the technical and commercial research and development needed to elevate Ceralink's energy saving process for flat glass lamination from bench scale to a self-supporting technology with significant potential for growth. Radio-frequency heating was any un-explored option for laminating glass prior to this program. With significant commercial success through time and energy savings in the wood, paper, and plastics industries, RF heating was found to have significant promise for the energy intensive glass lamination industry. A major technical goal of the program was to demonstrate RF lamination across a wide range of laminate sizes and materials. This was successfully accomplished, dispelling many skeptics' concerns about the abilities of the technology. Ceralink laminated panels up to 2 ft x 3 ft, with four sets processed simultaneously, in a 3 minute cycle. All major categories of interlayer materials were found to work with RF lamination. In addition to laminating glass, other materials including photovoltaic silicon solar cells, light emitting diodes, metallized glass, plastics (acrylic and polycarbonate), and ceramics (alumina) were found compatible with the RF process. This opens up a wide range of commercial opportunities beyond the initially targeted automotive industry. The dramatic energy savings reported for RF lamination at the bench scale were found to be maintained through the scale up of the process. Even at 2 ft x 3 ft panel sizes, energy savings are estimated to be at least 90% compared to autoclaving or vacuum lamination. With targeted promotion through conference presentations, press releases and internet presence, RF lamination has gained significant attention, drawing large audiences at American Ceramic Society meetings. The commercialization success of the project includes the establishment of a revenue-generating business model for providing process development and demonstrations for

    People often use the term "green energy" to refer to alternative energy technologies. But green energy doesn't guarantee maximum energy savings at a minimum cost--a common misconception. For school business officials, green energy means getting the lowest energy bills for the lowest construction cost, which translates into maximizing green energy…

  1. Renewable energy for Canada's northern communities - quantifying potential fuel savings

    International Nuclear Information System (INIS)

    Brothers, C.

    1998-01-01

    The probable impact of renewable energy technologies on fuel consumption in Canada's remote northern communities was discussed. These communities currently meet their electricity requirements using expensive diesel powered generators. It was noted that change to renewable energy in Canada's remote communities will only be made if the economic benefits can be clearly demonstrated. A study was conducted in Cambridge Bay, Northwest Territories, in which electrical load requirements and wind and solar resource data from the community was acquired to estimate savings in diesel fuel consumption for various renewable energy technologies. Wind was found to provide the most fuel displacement and was considered to be the most appropriate technology for these communities. A photovoltaic (PV) system of equivalent size would have significantly less impact on fuel savings in a community like Cambridge Bay, in part because a PV system would be poorly correlated on a seasonal basis with the energy requirements of the community. A wind-diesel system would be the most advantageous in terms of fuel savings due to its relatively high capacity factor, and due to the fact that is it is available year around. 4 refs., 1 tab., 4 figs

    About 20 years ago, we decided to make our house. Being working on the utilization of solar energy and with the objective of saving maximum conventional fuel and some family budget, we dicided to make use of maximum this free and clean fuel. After buying the land with proper orientation, we installed different cheap devices and left the proper provision for another devices to installed in future. At present we solar energy mainly for cooking, water heating for bath and dish washing, drying clothes/fruits/vegetables, purification (pasteurization) of water. In addition. we also use solar cells for some electrical devices like solar radio, solar lamp for emergency, charging batteries and mobile phone etc. For our family of five persons, having 3 coloured TV, 2 computers using many hours of Internet, without any use of fuel other than electricity and sun, our electricity consumption is of the order of 270 (dry/summer)-350 (wet/rainy) kWh/month, depending on the season (US$16-21/month). This is roughly 40-50% of the electricity consumed by my other colleagues who do not use solar energy. With this saving, the initial cost of solar devices (US$1200-1400) is already recovered. In this presentation, construction and results of working of these solar thermal, electrical devices and other energy saving means at our house are mentioned.(Author)

    In the spirit of the objectives of the Energy Plan 1995 in order to make more efficient use of energy and thus to reduce energy requirements, to promote the use of renewable energies, and to attach maximum importance to the ecological compatibility of the energy systems, among other project the provincial government of Styria is pursuing the option of consulting small and medium-sized enterprises in a target manner. Three years after being launched, this Ecological Company Consulting scheme for various lines of business is now producing successful results, demonstrating that energy saving, business profit and ecology can go hand in hand by example of numerous pilot projects. Trade-specific concepts have been elaborated for foodstuffs, carpenters and car repair and sales firms, bakeries and hairdressers and, most recently, for tourist industry business /hotels, bars, restaurants, etc.). The province of Styria, represented by the Energy Commissioner and the department of waste management, is co-operating closely in the Ecological Company Consulting scheme with the Styrian Chamber of Commerce and the Economy Promotion Institute (Wirtschaftsfoerderungsinstitut). In several cases, other provinces, the Federal Ministry of Environmental, Youth and Family Affairs, and the Federal Chamber of Commerce have adopted the results of this co-operation, while in some cases subsidy schemes are linked to these trade-specific concepts. In the course of the scheme, the aim is to investigate energy requirements, saving potentials and questions of waste management. (author)

    Energy has become a commodity with economic price in Slovakia. For years the energy price has not fulfilled the basic economic criteria - covering of production costs. It was used as one of the instruments of Governments social policy. But the situation is changing. Another phase of bringing the prices to a realistic level brought along a price increase by tens of percents. As the energy prices are increasing and there is a perspective that they will grow further all possible reserves and cheaper energy sources have to be identified. A simplified energetic model of Slovak economy identifies three basic energy-consumer kinds - industry, buildings and transport. Industry uses about one half of the Slovakia's yearly energy-consume. Aim private companies to survive in a competitive environment guarantees of a rational approach towards energy consume. The fact that even in companies that use high volumes of primary raw material the energy consume is the highest cost item (many times higher then the labour costs) is the main incentive for looking for saving possibilities in this area. A decrease of the industries' share in energy consume may indicate some positive trends. The energy consume in industries has dropped by ten percent within ten years and its share on the overall consume is approaching the 45-percent level. This was partially caused by decreasing production volumes or closing down of production in several companies. Energy consume of buildings represents about 35 - 40 percent of the national consume i.e. is on a level similar to other European countries. This is a sector is the most important. It is its structure that is important. Currently there are 1,8 million flat units in Slovakia. Family houses represent 48 percent and the remaining 52 percent go to flats. In close to 800-thousand family houses owned by the people living in them nobody has to stress the importance of energy savings. The user knows exactly how much energy has been used. The ownership is

    2017-11-02

    This chapter focuses on the methods used to estimate net energy savings in evaluation, measurement, and verification (EM and V) studies for energy efficiency (EE) programs. The chapter provides a definition of net savings, which remains an unsettled topic both within the EE evaluation community and across the broader public policy evaluation community, particularly in the context of attribution of savings to a program. The chapter differs from the measure-specific Uniform Methods Project (UMP) chapters in both its approach and work product. Unlike other UMP resources that provide recommended protocols for determining gross energy savings, this chapter describes and compares the current industry practices for determining net energy savings but does not prescribe methods.

  7. Economic Efficiency and Investment Implementation in Energy Saving Projects

    2017-09-01

    Full Text Available Investment in building thermoinsulation is a subject to appraisal for efficiency from the position of discounted cash flows taken specifically by energy saving. The appraisal of investment as optimal is attended by achieving the shortest term for investment implementation, the lowest investment outlays, the maximum total net value of energy savings, the shortest investment payback period. The complex application of the dynamic methods for appraising economic efficiency of an investment – net present value, internal rate of return, profitability index and discounted payback period, involves drawing of particular values which comparison definitely will show if this kind of investment is practically “attractive”. However, the question for significance weight of each of these indicators above in decision making for implementation a particular real investment still remains unsolved. This requires working out a system of criteria, priorities that can determine which of the indicators for economic efficiency of specific investment project will have the highest significance.

  9. Energy saving through trail following in a marine snail.

    Davies, Mark S; Blackwell, Janine

    2007-05-07

    Most snails and slugs locomote over a layer of mucus and although the resultant mucus trail is expensive to produce, we show that this expense can be reduced by trail following. When tracking over fresh conspecific trails, the marine intertidal snail Littorina littorea (L.) produced only approximately 27% of the mucus laid by marker snails. When tracking over weathered trails, snails adjusted their mucus production to recreate a convex trail profile of similar shape and thickness to the trail as originally laid. Maximum energy saving occurs when following recently laid trails which are little weathered. Many and diverse ecological roles for trail following have been proposed. Energy saving is the only role that applies across the Gastropoda and so may help to explain why trail following is such a well-established behaviour.

    Energy-saving target ratios (ESTR) for 17 APEC economies during 1991-2000 are computed in a total-factor framework. All nominal variables are transformed into real variables by the purchasing power parity (PPP) at the 1995 price level. The data envelopment analysis (DEA) approach is used to find the energy-saving target (EST) for APEC economies without reducing their maximum potential gross domestic productions (GDPs) in each year. Energy, labor, and capital are the three inputs, while GDP is the single output. Our major findings are as follows: (1) China has the largest EST up to almost half of its current usage. (2) Hong Kong, the Philippines, and the United States have the highest energy efficiency. (3) The energy efficiency generally increases for APEC economies except for Canada and New Zealand. (4) Chile, Mexico, and Taiwan have significantly improved their energy efficiency in the last 5 years. (5) An inverted U-shape relation exists between per capita EST and per capita GDP. (6) ESTR has a positive relation with the value-added percentage of GDP of the industry sector and a negative relation with that of the service sector.

    Highlights: • Time-of-use analysis to motivate kettle usage and consumption prediction. • Identification of households whose kettle usage and consumption is outside the norm. • Mathematical model to estimate water volume from consumed power measurements only. • Quantification of energy savings if a household uses its kettle more efficiently. • Kettle usage and demand prediction using an Adaptive Neuro Fuzzy Inference System. - Abstract: The availability of smart metering and smart appliances enables detecting and characterising appliance use in a household, quantifying energy savings through efficient appliance use and predicting appliance-specific demand from load measurements is possible. With growing electric kettle ownership and usage, lack of any efficiency labelling guidelines for the kettle, slow technological progress in improving kettle efficiency relative to other domestic appliances, and current consumer attitudes, urgent investigation into consumer kettle usage patterns is warranted. From an efficiency point of view, little can be done about the kettle, which is more efficient than other methods of heating water such as the stove top kettle. However, since a majority households use the kettle inefficiently by overfilling, in order to meet energy targets, it is imperative to quantify inefficient usage and predict demand. For the purposes of scalability, we propose tools that depend only on load measurement data for quantifying and visualising kettle usage and energy consumption, assessing energy wastage through overfilling via our proposed electric kettle model, and predicting kettle-specific demand, from which we can estimate potential energy savings in a household and across a housing stock. This is demonstrated using data from a longitudinal study across a sample of 14 UK households for a two-year period.

    Two energy-saving technologies tested recently at Marshall Space Flight Center use an induction motor operated in reverse (as an induction generator). In the first, energy ordinarily dissipated during load testing of machinery is recovered and returned to powerline. In the second, efficiency of wind-driven induction generator is improved, and useful range of windspeed is broadened. Both technologies take advantage of ac voltage developed across terminals of an induction motor when rotated at higher than-synchronous speed in the direction it normally turns when power is appled.

    Day by day greenhouse gas emissions increase dramatically. A passive adaptive method of lighting energy savings, daylight responsive systems are considered one of the best solutions for energy efficiency, saving and prevent CO 2 emissions. Results of an annual experiment which was held in Sakarya University proves the necessity of daylight responsive systems with a 41% energy saving and 942.5 kg of prevented CO 2 emissions Thinking this prevention is realized just only in a 36 m 2 room with the use of 8 luminaries spreading such systems to nationwide, a major amount of greenhouse gas emissions would be prohibited. On the other hand energy saving is not the only way to reduce CO 2 emissions. Again in Sakarya University a project has started to investigate the possibility of illumination of a complete building by using solar energy. This paper evaluates these mentioned systems both in energy efficiency, greenhouse gas emissions prevention and economic point of views. (author)

  5. Energy savings certificates 2011-2013 - Companies. Knowledge for action

    International Nuclear Information System (INIS)

    2013-03-01

    As fossil energy resources are depleted and the environmental impacts of their use are increasingly addressed, energy costs will continue to rise. In this context it is vital for businesses - in the service sector, industry or agriculture - to take steps now to start managing their energy consumption. A number of tools and mechanisms are currently being implemented to help companies in this process, at the national and European levels. Among these, Energy Savings Certificates (ESCs) were introduced in France by the Energy Policy Law of 13 July 2005, with the aim of achieving energy savings in sectors of dispersed activity, mainly buildings, but also light industry, agriculture and transport. For businesses this mechanism is an additional financial leverage tool that can be used to support their energy management projects. Under this scheme energy suppliers must promote energy-efficient investments, and thus are potential sources of financing for project owners. The Grenelle environmental conference forcefully reiterated the need to take action, in particular to renovate existing building stock. In order to achieve the ambitious goals that have been set, the financial mechanisms put into place, including the ESC scheme, must be amplified. Following the first conclusive test period (2006-2009), the ESC scheme is being ramped up during a second and more ambitious three-year period that began on 1 January 2011. The present document is intended to inform companies of changes in the ESC scheme to be implemented for the second period covering 2011-2013. This guidance is divided into two parts: the first section describes the principles of the ESC scheme, and the second offers advice to companies that want to use this scheme for an energy management project. You will also find a practical information sheet listing all the steps to be taken to submit an ESC claim

  6. Energy efficiency: a source of savings; a priority objective

    International Nuclear Information System (INIS)

    Bethencourt, Anne de; Chorin, Jacky

    2013-01-01

    Energy efficiency is defined as consumption of less energy whilst delivering the same service. Significant progress has been made through the impact of technology, price increases and awareness of waste. Too often viewed as a constraint, energy efficiency nonetheless constitutes the leading potential source of domestic energy for the 2020 goal. Energy efficiency is or will be (depending on the will of the stakeholders, public authorities and society as a whole) a key market for the future and a pathway to creative innovation. Everything is pointing in that direction: the obligation to reduce greenhouse gas emissions fourfold, the new European Directive on Energy Efficiency to be incorporated, the expected increase in energy prices, the presence in France of industry leaders and of a small-scale but important industry in this sector. The goals in energy efficiency entail: - at Community level, that the objective of 20% energy savings for the 2020 goal becomes binding; - at national level, that public policies for energy efficiency are part of a long-term vision, based on the achievements of the Grenelle Environment Forum and avoid sending out any wrong signals which might adversely affect progress. The ESEC proposals are built around the following four themes: - (residential and service sector) buildings: Make energy efficiency into a real sector and a new opportunity 'work together', Optimise tools and regulations, Be innovative in terms of financial support; - fuel poverty; - industry and agriculture; - the particular situation of the overseas departments

    Energy efficiency services are growing in Europe but their role is still limited. In order to evaluate the potential, we focused first of all on policy, economical and environmental mechanisms that support their development. European natural gas and electricity markets, that are now almost wholly de-regulated, are analysed and compared to their historical structure. By introducing uncertainty on energy prices, this new deal translates better the real energy costs. Energy performance contracts (EPC) limit the impact of these uncertainties on the customer energy bills by guaranteeing a financial result. As a result of the modelling of these contracts, namely operation and maintenance ones, we prove that they transfer technical and financial risks from building owners to energy service companies (ESCO) making energy saving measures easier and less expensive at the same time. These contracts are relatively widespread for heating or compressed-air processes but remain marginal for air-conditioning systems. So new methods were needed to guarantee on the long terms the efficiency of air-conditioning systems demand (1) to master the process and its performances and (2) to be able to determine precisely the energy saving potential and its realisation costs. A detailed energy audit is thus necessary for which we propose a guidance. Conclusions of audits carried out prove that energy saving potential is mainly located in equipment management and control. These optimizations are not always carried out because of a lack of contractual incentive and due to the weaknesses of audit methods. Through the involvement of an independent expert, the mandatory and regular inspection of air-conditioning systems may allow to verify and guide such practices. A three-step analysis procedure has been developed in order to maximize the inspection potential and to get higher benefits from service contracts. (author)

    The overall purpose of this report on energy-saving measures is to provide the Estonian Ministry of Economics and Communication with an overview of the energy consumption on poultry farms at a national level. This report compromises detailed information on energy consumption per ton of broiler meat, egg and young laying hen produced in Estonia and Denmark, respectively, based on field investigations and Danish statistics. To collect information on electricity consumption within Estonian poultry farming on a national level, three pilot farms were analysed with regard to the use of energy consumption on each farm. Results from the three farms are presented in Appendix 1. In addition, a calculation of national energy consumption within chicken meet production, egg production and breeding of young laying hens is presented in this report. The calculation shows the difference between the Danish and Estonian energy consumption on poultry farms. This report presents a proposal for a ten-year development plan for the reduction of the energy consumption on Estonian poultry farms. (au)

  13. Year-round daylight saving time will save more energy in India than corresponding DST or time zones

    2012-01-01

    Many countries have experimented with daylight saving time (DST) to save energy and to align human activities more closely to the daily cycle of light and darkness. Using a novel methodology, we estimate the year-round energy savings to be obtained from advancing Indian Standard Time (IST), from the introduction of DST, and from dividing the country into two time zones. We find that the option of advancing IST consistently saves more energy than the corresponding DST option, which in turn saves more energy than the corresponding time zones option. This is because the energy benefits of advancing IST accrue for the entire year throughout the country, whereas the benefits of DST are confined to summer months and the benefits of two time zones are largely in the lower energy consuming eastern region. We recommend advancing IST by half-hour to being six hours ahead of UTC. This confers the advantages of DST and time zones without their disadvantages and is forecast to save more than 2 billion kWh of electricity every year during evening peaks that are difficult to supply. While these results are India-specific, similar exercises would be useful to many other countries. - Highlights: ► Advancing IST (YRDST) consistently saves more energy than the corresponding DST. ► DST consistently saves more energy than dividing India into two time zones. ► There are also many non-energy benefits of advancing IST. ► Results are for India; countries with DST may find it useful to consider YRDST.

    Design parameters, like blade number, blade outlet angle and impeller outlet diameter, affect pump performance and energy consumption. Deep well pumps with splitter blades (DWPwsb) are manufactured to achieve energy saving and improve efficiency. Splitter blades are generally located at the centerline of the main blades. Blade number and blade discharge angle should be conveniently determined when splitter blades are used on the impellers. In this study, impellers having different numbers of blades (z = 5, 6, 7) with and without splitter blades (35%, 60% and 80% of the main blade length) were tested in a deep well pump. Tests have been conducted on a total of 12 impellers, and the characteristics of deep well pumps without splitter blade (DWPwosb) and DWPwsb were obtained experimentally. These results show that splitter blades cause negative effects on pump performance in impellers with blade numbers of 6 and 7. When the splitter blade is added to the impeller with the blade number of 5, the efficiency increases with flow up to 10 l/s flow rate, after which it decreases as the splitter blade length increases. The highest efficiency and the lowest energy consumption were obtained in DWPwsb with 80% of the main blade length. At the best efficiency point (b.e.p), an energy saving of 6.6% and an improvement of 1.14% in efficiency were achieved. An analysis of the additional cost of the splitter blade and the application in an agricultural area were performed.

    As the third period of Energy Saving Certificates (EEC) enter their third period, a first article comments the evolutions of the principles and modalities of this arrangement under the influence of the directive on energy efficiency, and how the involved actors cope with these evolutions. The main differences with the previous period are presented. They concern energy providers and eligible bodies, the level of 'cumac' KWh (cumac stands for cumulated and actualised), controls and sanctions, eligible operations, and modalities. A second article describes how the arrangement has been simplified by means of a declarative system, and outlines that the control has been strengthened and may lead to heavy sanctions. The next articles comment the consequences for the building sector, notably for thermal insulation, the implications for communities (notably for the development of the use of LEDs for public lighting and for heat networks), for the transport sector (fuel dealers, good transport optimisation programs, fossil energy saving in logistic and mobility programs), and for the agriculture sector. Some key figures related to the second period (January 2011 - December 2014) are given: number of supplied cumac KWh, distribution of EECs among sectors, evolution of the weighted monthly average price of EECs

    In recent years, there has been a significant increase in the cost of fuel gas, fuel oil and electricity and much thought has been given to the use of solar energy. Living in a solar heated house gives peace of mind and body and it makes good sense in mountainous regions. Severe winters in such regions make more energy for standard living activities in buildings necessary. This paper discusses passive solar building design as an energy saving solution. In this type of design, windows, walls and floors act as storage and distribution devices for solar energy in winter and deflect solar heat in summer. Passive solar design techniques influence the choice of building site, design and materials within the general framework of enriching the quality of life of the inhabitants. As a result, natural resources are saved and the environment is conserved for future generations. In conclusion, it is seen that passive design keeps a home cool and comfortable in summer and warm and cozy in winter with minimal heating and cooling requirements.

  18. Tradable certificates for renewable electricity and energy savings

    International Nuclear Information System (INIS)

    Bertoldi, Paolo; Huld, Thomas

    2006-01-01

    Tradable green certificates (TGCs) schemes have been developed and tested in several European countries to foster market-driven penetration of renewables. These certificates guarantee that a specific volume of electricity is generated from renewable-energy source (RES). More recently certificates (tradable white certificates (TWCs)) for the electricity saved by demand-side energy-efficiency measures (EEMs) have been introduced in some European countries. Recent advances in information and communication technology have opened up new possibilities for improving energy efficiency and increasing utilization of RESs. Use of technological resources such as the Internet and smart metering can permit real-time issuing and trading of TGCs. These technologies could also permit issuing of TWC. This paper reviews current renewable TGC and TWCs schemes in Europe and describes the possibilities for combining them in an Internet-based system. In the proposed combined tradable certificate scheme, both RESs and demand-side EEMs could bid in real time through the Internet to meet a specific obligation. The energy savings from the demand-side measures would be equivalent to the same amount of green electricity production. The paper describes the needed common targets and obligations, the certificate trading rules and the possible monitoring protocol. In particular, the paper focuses on the TWCs verification issues, including the assessment of the baseline, as these poses additional problems for TWCs compared to TGCs

    This four-page publication describes the U.S. Department of Energy's (DOE's) streamlined energy savings performance contracting, or ''Super ESPC,'' process, which is managed by DOE's Federal Energy Management Program (FEMP). Under a Super ESPC, a qualifying energy service company (ESCO) from the private sector pays for energy efficiency improvements or advanced renewable energy technologies (e.g., photovoltaic systems, wind turbines, or geothermal heat pumps, among others) for a facility of a government agency. The ESCO is then repaid over time from the agency's resulting energy cost savings. Delivery orders under these contracts specify the level of performance (energy savings) and the repayment schedule; the contract term can be up to 25 years, although many Super ESPCs are for about 10 years or less

    We conducted a re-analysis of data supplied by the New Buildings Institute and the US Green Buildings Council on measured energy use data from 100 LEED-certified commercial and institutional buildings. These data were compared to the energy use of the general US commercial building stock. We also examined energy use by LEED certification level, and by energy-related credits achieved in the certification process. On average, LEED buildings used 18-39% less energy per floor area than their conventional counterparts. However, 28-35% of LEED buildings used more energy than their conventional counterparts. Further, the measured energy performance of LEED buildings had little correlation with certification level of the building, or the number of energy credits achieved by the building at design time. Therefore, at a societal level, green buildings can contribute substantial energy savings, but further work needs to be done to define green building rating schemes to ensure more consistent success at the individual building level. Note, these findings should be considered as preliminary, and the analyses should be repeated when longer data histories from a larger sample of green buildings are available. (author)

    The Missouri Agricultural Energy Saving Team-A Revolutionary Opportunity (MAESTRO) program brought together a team of representatives from government, academia, and private industry to enhance the availability of energy efficiency services for small livestock producers in the State of Missouri. The Missouri Department of Agriculture (MDA) managed the project via a subcontract with the University of Missouri (MU), College of Agriculture Food and Natural Resources, MU Extension, the MU College of Human Environmental Sciences, the MU College of Engineering, and the Missouri Agricultural and Small Business Development Authority (MASBDA). MU teamed with EnSave, Inc, a nationally-recognized expert in agricultural energy efficiency to assist with marketing, outreach, provision of farm energy audits and customer service. MU also teamed with independent home contractors to facilitate energy audits of the farm buildings and homes of these livestock producers. The goals of the project were to: (1) improve the environment by reducing fossil fuel emissions and reducing the total energy used on small animal farms; (2) stimulate the economy of local and regional communities by creating or retaining jobs; and (3) improve the profitability of Missouri livestock producers by reducing their energy expenditures. Historically, Missouri scientists/engineers conducted programs on energy use in agriculture, such as in equipment, grain handling and tillage practices. The MAESTRO program was the first to focus strictly on energy efficiency associated with livestock production systems in Missouri and to investigate the applicability and potential of addressing energy efficiency in animal production from a building efficiency perspective. A. Project Objectives The goal of the MAESTRO program was to strengthen the financial viability and environmental soundness of Missouri's small animal farms by helping them implement energy efficient technologies for the production facility, farm

    Energy bandwidth studies of U.S. manufacturing sectors can serve as foundational references in framing the range (or bandwidth) of potential energy savings opportunities. This bandwidth study examines energy consumption and potential energy savings opportunities in U.S. iron and steel manufacturing. The study relies on multiple sources to estimate the energy used in six individual process areas and select subareas, representing 82% of sector-wide energy consumption. Energy savings opportunities for individual processes and subareas are based on technologies currently in use or under development; the potential savings are then extrapolated to estimate sector-wide energy savings opportunity.

    Full Text Available Macau is building a world tourism and leisure center. In the context of flourishing hospitality development, energy issues have attracted more and more attention in recent years. On the basis of the field survey of 28 hotels, an evaluation index system is built to assess the status of energy-saving and environmental protection practices in the hospitality industry in Macau. This system is built by selecting some credits from Leadership in Energy and Environmental Design (LEED and adding several new indices according to the social and economic characteristics of Macau. The results show that the hotels have made significant efforts to improve the energy efficiency in recent years. A total of 71.4% of the hotels have formulated and implemented the energy-saving and environmental protection programs. However, there is an apparent gap in energy and environmental performance between different star-level hotels. The higher is the star-level of a hotel, the higher enthusiasm on energy-saving a hotel has, e.g., 63.6% of the 5-star hotels carried out the carbon auditing and energy management measures, but there is no 2-star hotel that adopted them. The energy-saving performance can be great improved if more efforts are made in the future, especially for the 2-star hotels. Finally, we put forward some suggestions for how to bridge this gap and present a possible roadmap for the further improvement of energy efficiency of the hotel industry in Macau. The results from this work are useful to help the government and hotel managers to take actions for improving the energy utilization and efficiency of the hospitality industry in Macau.

    The objective of this work was to determine the realization rate of energy and cost savings from the Department of Energy’s Energy Savings Performance Contract (ESPC) program based on information reported by the energy services companies (ESCOs) that are carrying out ESPC projects at federal sites. Information was extracted from 156 Measurement and Verification (M&V) reports to determine reported, estimated, and guaranteed cost savings and reported and estimated energy savings for the previous contract year. Because the quality of the reports varied, it was not possible to determine all of these parameters for each project. For all 156 projects, there was sufficient information to compare estimated, reported, and guaranteed cost savings. For this group, the total estimated cost savings for the reporting periods addressed were $210.6 million, total reported cost savings were $215.1 million, and total guaranteed cost savings were $204.5 million. This means that on average: ESPC contractors guaranteed 97% of the estimated cost savings; projects reported achieving 102% of the estimated cost savings; and projects reported achieving 105% of the guaranteed cost savings. For 155 of the projects examined, there was sufficient information to compare estimated and reported energy savings. On the basis of site energy, estimated savings for those projects for the previous year totaled 11.938 million MMBtu, and reported savings were 12.138 million MMBtu, 101.7% of the estimated energy savings. On the basis of source energy, total estimated energy savings for the 155 projects were 19.052 million MMBtu, and reported saving were 19.516 million MMBtu, 102.4% of the estimated energy savings.

    Biopulping is defined as the treatment of wood chips with lignin-degrading fungi prior to pulping. Fungal pretreatment prior to mechanical pulping reduces electrical energy requirements during refining or increases mill throughput, improves paper strength, reduces the pitch content, reduces cooking time for sulfite pulping, and reduces the environmental impact of pulping. The recent work involved scaling up the biopulping process towards the industrial level, investigating both the engineering and economic feasibility of the technology. The authors envision the process to be done in either a chip-pile or silo-based system for which several factors need to be considered. These factors include the degree of decontamination, a hospitable environment for the fungus, and the overall process economics. Currently, treatment of the chips with low pressure steam is sufficient for decontamination. Furthermore, a simple, forced ventilation system can be used to maintain the proper temperature, humidity, and moisture content throughout the chip bed, thus promoting uniform growth of the fungus. The pilot-scale trial resulted in the successful treatment of 4 tons, of wood chips (dry weight basis) with results comparable to those on a laboratory scale. For mechanical pulping, a 2-week treatment results in approximately 30% energy savings that, considering the additional equipment and operating costs, results in an overall savings of $9 to $20/ton of pulp in a chip-pile system. The other benefits that biopulping confers improve the economics considerably A larger, 40-ton trial was also successful, with energy savings and paper properties comparable with the laboratory scale

    Isoard, Stephane; Wiesenthal, Tobias

    2005-01-01

    This paper reports a climate change policy scenario compatible with long-term sustainable objectives set at EU level (6th Environment Action Plan). By setting ambitious targets for GHG emissions reduction by 2030, this normative scenario relies on market-based instruments and flexible mechanisms. The integrated policy that is simulated (i.e. addressing energy, transport, agriculture and environmental impacts) constitutes a key outlook for the next 5-year report of the European Environment Agency (EEA). This scenario highlights what it would take to drastically curb EU GHG emissions and how much it might cost. The findings show that such a 'deep reduction' climate policy could work as a powerful catalyst for (1) substantial energy savings, and (2) promoting sustainable energy systems in the long term. The implications of this policy lever on the energy system are many-fold indeed, e.g. a substantial limitation of total energy demand or significant shifts towards energy and environment-friendly technologies on the supply side. Clear and transparent price signals, which are associated with market-based instruments, appear to be a key factor ensuring sufficient visibility for capital investment in energy efficient and environment-friendly options. Finally it is suggested that market-based policy options, which are prone to lead to win-win situations and are of particular interest from an integrated policy-making perspective, would also significantly benefit from an enhanced energy policy framework

    This paper presents a study of the potential energy savings by implementing dc distribution systems for residential applications. In general, it is commonly accepted that the use of dc voltage improves the efficiency of the distribution, due to a decrease in the conduction losses and an efficiency...... improvement in the power converter units. However, for residential applications, the efficiency is not always improved.

    Fuel poverty is a critical issue for a globally ageing population. Longer heating/cooling requirements combine with declining incomes to create a problem in need of urgent attention. One solution is to deploy technology to help elderly users feel informed about their energy use, and empowered to take steps to make it more cost effective and efficient. This study subjects a broad cross section of energy monitoring and home automation products to a formal ergonomic analysis. A high level task analysis was used to guide a product walk through, and a toolkit approach was used thereafter to drive out further insights. The findings reveal a number of serious usability issues which prevent these products from successfully accessing an important target demographic and associated energy saving and fuel poverty outcomes. Design principles and examples are distilled from the research to enable practitioners to translate the underlying research into high quality design-engineering solutions.

    GRIGORAS, G.

    2010-05-01

    Full Text Available The power/energy losses reduction in distribution systems is an important issue during planning and operation, with important technical and economical implications. Thus, the energy losses minimization implies not only the technical improvement of the network, through its renewal with the introduction of the technological innovations in the equipment and circuit components as well as the optimal planning of the design and development of the network, but also requires the use of the methods and software tools to facilitate the operation process. The paper presents a strategy for power/energy saving which replacement of the 6 kV voltage level with 20 kV voltage level in correlation with the extent of using efficient transformers. In this line, different urban distribution networks were analyzed using fuzzy techniques.

    Major energy savings can be achieved in the Netherlands by bringing demand and supply of heating of cooling closer together and by connecting processes in the correct energetic order. This is already done when one party owns an entire chain, for example in the case of refineries. As soon as several parties are involved, this is seldom achieved. Analysis shows that technical incompetence is seldom an obstacle. Most of the time organizational and economic actors are to blame. Moreover, main influences come from the attitude of the required investors and the position of the government. [mk] [nl

  2. Grant management procedure for energy saving TDM-PONs

    2018-01-01

    In order to minimize energy consumption in Time Division Multiplexing-Passive Optical Network (TDM-PON), IEEE and ITU-T have mandated sleep mode mechanism for Optical Network Units (ONUs) in the latest TDM-PON standards (e.g. IEEE P1904.1 SIEPON, ITU-T G.sup45). The sleep mode mechanism is a promising mean for maximizing energy saving in an ONU. An ONU in sleep mode flips between sleep and active state depending on the presence or absent of upstream and downstream frames. To ensure Quality of Service (QoS) of upstream frames, the recent TDM-PON standards introduced an early wake-up mechanism, in which an ONU is forced to leave the sleep state on upstream frame arrival. When the Optical Line Terminal (OLT) of a TDM-PON allows early wake-up of its connected ONUs, it allocates gratuitous grants for the sleeping ONUs along with allocating upstream grants for the ONUs in active state. Note that, the gratuitous grants control message sent periodically by the OLT on Inter-Gratuitous grant Interval (IGI) time. After leaving sleep state due to the arrival of upstream frame, the ONU uses its allocated gratuitous grant to send a control message mentioning the amount of upstream bandwidth (upstream grant) required in order to forward the remaining frames in its buffer. However, the existing early wake-up process of ONU can lead to increase the energy consumption of an ONU. It is because of the ONU wakes-up immediately from the sleep state on arrival of the upstream frame, but even so, it needs to wait for forwarding the frame until its allocated gratuitous grant period, resulting in spending energy unnecessarily. In addition, current energy saving solution for TDM-PONs do not provide a clear solution on how to manage different types of grants (e.g. listening grant, upstream transmission grant) within a Dynamic Bandwidth Allocation (DBA) polling cycle. To address this problem, we propose a state-of-art Grant Management Procedure (GMP) in order to maximize energy saving in a TDM

    Buildings are among the largest consumers of energy. Part of the energy is wasted due to the habits of users and equipment conditions. A solution to this problem is efficient energy usage. To this end, an energy audit can be conducted to assess the energy efficiency. This study aims to analyze the energy usage of a primary school and identify the potential energy reductions and cost savings. A preliminary audit was conducted, and several energy conservation measures were proposed. The energy conservation measures, with reference to the MS1525:2007 standard, were modelled to identify the potential energy reduction and cost savings. It was found that the school's usage of electricity exceeded its need, incurring an excess expenditure of RM 2947.42. From the lighting system alone, it was found that there is a potential energy reduction of 5489.06 kWh, which gives a cost saving of RM 2282.52 via the improvement of lighting system design and its operating hours. Overall, it was found that there is a potential energy reduction and cost saving of 20.7% when the energy conservation measures are earnestly implemented. The previous energy intensity of the school was found to be 50.6 kWh/m2/year, but can theoretically be reduced to 40.19 kWh/mm2/year. PMID:25485294

    The petroleum refining industry in the United States is the largest in the world, providing inputs to virtually any economic sector,including the transport sector and the chemical industry. The industry operates 146 refineries (as of January 2004) around the country,employing over 65,000 employees. The refining industry produces a mix of products with a total value exceeding $151 billion. Refineries spend typically 50 percent of cash operating costs (i.e., excluding capital costs and depreciation) on energy, making energy a major cost factor and also an important opportunity for cost reduction. Energy use is also a major source of emissions in the refinery industry making energy efficiency improvement an attractive opportunity to reduce emissions and operating costs. Voluntary government programs aim to assist industry to improve competitiveness through increased energy efficiency and reduced environmental impact. ENERGY STAR (R), a voluntary program managed by the U.S. Environmental Protection Agency, stresses the need for strong and strategic corporate energy management programs. ENERGY STAR provides energy management tools and strategies for successful corporate energy management programs. This Energy Guide describes research conducted to support ENERGY STAR and its work with the petroleum refining industry.This research provides information on potential energy efficiency opportunities for petroleum refineries. This Energy Guide introduces energy efficiency opportunities available for petroleum refineries. It begins with descriptions of the trends, structure, and production of the refining industry and the energy used in the refining and conversion processes. Specific energy savings for each energy efficiency measure based on case studies of plants and references to technical literature are provided. If available, typical payback periods are also listed. The Energy Guide draws upon the experiences with energy efficiency measures of petroleum refineries worldwide

    China's carbon dioxide (CO 2 ) emission ranks highest in the world. China is committed to reduce its CO 2 emission by 40% to 45% from the 2005 levels by 2020. To fulfill the target, China's CO 2 emission reduction must exceed 6995 million tons. Energy consumption and CO 2 emission of China's urban district heating (UDH) are increasing. The current policy implemented to improve UDH focuses on replacing coal with natural gas to reduce energy consumption and CO 2 emission to some extent. This paper proposes that heat pump heating (HPH) could serve as a replacement for UDH to help realize energy-saving and emission-reduction goals to a greater extent. The paper also analyzes the impact of this replacement on the heating and power generation sectors. The results show that replacing coal-based UDH with HPH decreases energy consumption and CO 2 emission by 43% in the heating sector. In the power generation sector, the efficiency of power generation at the valley electricity time increases by 0.512%, and the ratio of peak–valley difference decreases by 16.5%. The decreases in CO 2 emission from the heating and power generation sectors cumulatively account for 5.55% of China's total CO 2 emission reduction target in 2020. - Highlights: ► Replacing urban district heating with heat pump heating. ► Impact of heat pump heating on heating and power generation sectors. ► Potential of energy saving and emission reduction for heat pump heating. ► China should adjust current urban heating strategy

    One important rationale for bio-energy systems is their potential to save fossil energy. Converting a conventional sugar mill into a bio-energy process plant would contribute to fossil energy savings via the extraction of renewable electricity and ethanol substituting for fossil electricity and gasoline, respectively. This paper takes a closer look at the Thai sugar industry and examines two practical approaches that will enhance fossil energy savings. The first one addresses an efficient extraction of energy in the form of electricity from the excess bagasse and cane trash. The second while proposing to convert molasses or sugar cane to ethanol stresses the use of bagasse as well as distillery spent wash to replace coal in meeting ethanol plants' energy needs. The savings potential achieved with extracting ethanol from surplus sugar versus current practice in sugar industry in Thailand amounts to 15 million barrels of oil a year. Whether the saving benefits could be fully realized, however, depends on how well the potential land use change resulting from an expansion of ethanol production is managed. The results presented serve as a useful guidance to formulate strategies that enable optimum utilization of biomass as an energy source. (author)

    This final report for the Swiss Federal Office of Energy (SFOE) takes a look at the repercussions on the power supply network that are caused by energy-saving lamps (ESL). These effects result from the operation of the lamps' electronic ballasts which operate at high frequencies. The most noticeable network repercussions that are caused by the rapid current variations in the ESL are discussed, as are ways of considerably reducing them. As for effects on the grid, the authors state that it is not to be expected that any problematic mains feedback will result in practice, particularly not in the well-dimensioned Swiss electricity grid. The methods used in the analysis and the detailed results obtained are presented in tabular and graphical form and discussed.

    2008-10-01

    Early experiences with energy savings certificates (ESCs) have revealed both their merit and the challenges associated with them. In the United States, there has been little activity to date, so any lessons must be drawn from experiences in Italy, the United Kingdom (UK), France, and elsewhere. The staying power of European examples, particularly in Italy, demonstrates that ESCs can help initiate more efficiency projects. Although a robust market for renewable energy certificates (RECs) has emerged in both the voluntary and policy compliance contexts in the United States, ESCs have yet to gain significant traction. This report looks at the opportunity presented by ESCs, the unique challenges they bring, a comparison with RECs that can inform expectations about ESC market development, and the solutions and best practices early ESC market experience have demonstrated. It also examines whether there are real market barriers that have kept ESCs from being adopted and what structural features are necessary to develop effective trading programs.

    Early experiences with energy savings certificates (ESCs) have revealed their merits and the challenges associated with them. While in the United States ESC markets have yet to gain significant traction, lessons can be drawn from early experiences in the states of Connecticut and New York, as well as from established markets in Italy, France, and elsewhere. The staying power of European examples demonstrates that ESCs can help initiate more efficiency projects. This article compares ESCs with renewable energy certificates (RECs), looks at the unique opportunities and challenges they present, and reviews solutions and best practices demonstrated by early ESC markets. Three major potential ESC market types are also reviewed: compliance, voluntary, and carbon. Additionally, factors that will benefit ESC markets in the United States are examined: new state EEPS policies, public interest in tools to mitigate climate change, and the growing interest in a voluntary market for ESCs.

  20. Saving energy for the data collection point in WBAN network

    2017-11-01

    Wireless sensor networking (WSN) has been rapidly developed and become essential in various domains including health care systems. Such systems use WSN to collect real-time medical sensed data, aiming at improving the patient safety. For instance, patients suffered from adverse events, i.e., cardiac or respiratory arrests, are monitored so as to prevent them from getting harm. Sensors are placed on, in or near the patients' body to continuously collect sensing data such as the electrocardiograms, blood oxygenation, breathing, and heart rate. In this case, the sensors form a subcategory of WSN called wireless body area network (WBAN). In WBAN, sensing data are sent to one or more data collection points called personal server (PS). The role of PS is important since it forwards sensed data, to a medical server via a Bluetooth/WLAN connection in real time to support storage of information and real-time diagnosis, the device can also issue a notification of an emergency status. Since PS is a battery-based device, when its battery is empty, it will disconnect the sensed medical data with the rest network. To best of our knowledge, very few studies that focus on saving energy for the PS. To this end, this work investigates the trade-off between energy consumption for wireless communication and the amount of sensing data. An energy consumption model for wireless communication has been proposed based on direct measurement using real testbed. According to our findings, it is possible to save energy for the PS by selecting suitable wireless technology to be used based on the amount of data to be transmitted.

    The article shows the development of energy consumption since the seventies in three main energy consuming sectors: industry, residential services and transport. While the energy intensity and consumption in the industrial sector have considerably decreased- taking 100 as index in 1973, this was 68 in 1988-in the other sectors, the increase of comfort in houses and business offices, as well as the number or automobiles, have made consumption in these sectors increase despite the efforts made in the improvement of return of installations and reduction of cars consumption. In the industry, large energy savings coincide with remarkable technological innovations and for the future, the achieved savings and future trends, as well as conditions for the energy saving, are analyzed for the rest of the sectors.

    Savings from electric energy efficiency measures and programs are often expressed in terms of annual energy and presented as kilowatt-hours per year (kWh/year). However, for a full assessment of the value of these savings, it is usually necessary to consider the measure or program's impact on peak demand as well as time-differentiated energy savings. This cross-cutting protocol describes methods for estimating the peak demand and time-differentiated energy impacts of measures implemented through energy efficiency programs.

A technique was developed to recapture enthalpy from a continuous flow drying system and to carry that energy back into the grain kernels. Process design assures that the recaptured energy is used to provide latent heat for evaporation of moisture from the kernels. Maximum kernel temperatures are tightly controlled by the design and can be selected through the system controls. The drying system process has been simulated, the mechanical design for a prototype was completed, and the prototype has been fabricated and installed. Simulation results show energy use that is a fraction of that required by the most efficient heat assisted grain dryer systems available at this time. Unfortunately, project time has expired, funding has been exhausted, and the system has yet to be fully run in order to validate the process design. Additional development work is required to run tests with the prototype, improve the simulation model, optimize the process and mechanical design, and bring this energy saving system to market.

    Full Text Available Small and medium enterprises (SMES play an important role in Taiwan’s economy. The reduction of energy costs and carbon dioxide (CO2 emissions are critical to preserving the environment. This paper uses the experimental results from 65 sites, gathered over two years since 2012, to determine how the integration of Internet communication, cloud computing technologies and a cloud energy management service (cloud EMS can reduce energy consumption by cost-effective means. The EMS has three levels: infrastructure as a service (IaaS, platform as a service (PaaS and software as a service (SaaS. Working jointly with ChungHwa Telecom, Taiwan’s leading telecom service provider, data from detection devices, control devices, air-conditioning and lighting systems are all uploaded to a cloud EMS platform, to give a so called intelligent energy management network application service platform (IEN-ASP. Various energy saving management functions are developed using this platform: (1 air conditioning optimization; (2 lighting system optimization; (3 scheduling control; (4 power billing control and (5 occupancy detection and timing control. Using the international performance measurement and verification protocol (IPMVP, the energy used at the test sites, before and after the use of the IEN-ASP, are compared to calculate the energy saved. The experimental results show that there is an average energy saving of 5724 kWh per year, which represents a saving ratio of 5.84%. This translates to a total reduction in CO2 emissions of 9,926,829 kg per year. Using the data collected, a regression model is used to demonstrate the correlation between the power that is consumed, the energy that is saved and the area of the sites. Another interesting result is that, if the experimental sites are maintained by experienced electricians or other personnel and EMS protocols are followed, the energy saving can be as great as 6.59%.

    CO2 reduction and fossil fuel saving represent two of the cornerstones of the environmental commitments of all the countries of the world. The first engagement is of a medium to long term type, and unequivocally calls for a new energetic era. The second delays in time the fossil fuel technologies to favour an energetic transition. In order to sustain the two efforts, new immaterial markets have been established in almost all the countries of the world, whose exchanges (purchases and sales) concern CO2 emissions and equivalent fossil fuels that have not been emitted or burned. This paper goes deep inside two aspects not yet exploited: specific CO2 emissions and equivalent fossil fuel burned, as a function of compressed air produced. Reference is made to the current compressor technology, carefully analysing CAGI's (Compressed Air Gas Institute) data and integrating it with the PNUEROP (European Association of manufacturers of compressors, vacuum pumps, pneumatic tools and allied equipment) contribution on the compressor European market. On the base of energy saving estimates that could be put in place, this article also estimates the financial value of the CO2 emissions and fossil fuels avoided.

    Full Text Available An important problem of reducing energy consumption and dioxide emissions in the stage of construction and operation of mine belt conveyors is connected with their broad use in the industry. However, this notion is related to a reduction of electric energy consumption for conveyor drive and for production of conveyor components and assemblies (belts, rollers, load-bearing structure etc.. An essential role is played by an increased life of belt conveyors assemblies and components, principally belts. A reduced electric energy consumption results in a decreased CO2 emissions, e.g. hard coal – fired power station issues 0.28 kg CO2 per production of 1 kWh, in to answer production of 1 t steel accounts for 3.2 t CO2 emissions. The subject-matter presented in the paper concerning energy-saving in the horizontally and inclined mine belt conveyors installed in a Polish colliery – Anna, Jankowice and Marcel, has a big economic significance and it is important from the point of view of environmental protection.

    Long Beach Gas and Oil (LBGO), the public gas utility in Long Beach, California, partnered with the U.S. Department of Energy (DOE) to develop and implement solutions to build a new, low-energy modular office building that is at least 50% below requirements set by Energy Standard 90.1-2007 of the American Society of Heating, Refrigerating, and Air-conditioning Engineers (ASHRAE), the American National Standards Institute (ANSI), and the Illuminating Engineering Society of America (IESNA) as part of DOE’s Commercial Building Partnerships (CBP) program.3 The LBGO building, which demonstrates that modular construction can be very energy efficient, is expected to exceed the ASHRAE baseline by about 45%. The new 15,000-square foot (ft2) LBGO office building has two stories and houses private offices, open-plan cubicle offices, and a conference room and call center on the second floor. The building’s modular nature allowed LBGO to realize the cost benefits of fasttracked construction while saving substantial energy and reducing operational costs. The project was funded by the utility’s ratepayer revenue, which imposed a tight budget limit. The design process was a collaborative effort involving LBGO and its design-build team, Lawrence Berkeley National Laboratory (Berkeley Lab), and subcontractors Stantec (formerly Burt Hill) and LHB Inc. The team proposed efficiency measures based on computer modeling of the building in full compliance with ASHRAE 90.1-2007; in the modeled building, the lighting and cooling systems were the largest energy users, so increasing the efficiency of these systems was a top priority. Promising measures were modeled to estimate their energy performance, and each measure was evaluated for its feasibility within the budget.

    2014-09-01

    Full Text Available Scratchpad memories have been shown to reduce power consumption, but the different characteristics of nanometer scale processes, such as increased leakage power, motivate an examination of how the benefits of these memories change with process scaling. Process and application characteristics affect the amount of energy saved by a scratchpad memory. Increases in leakage as a percentage of total power particularly impact applications that rarely access memory. This study examines how the benefits of scratchpad memories have changed in newer processes, based on the measured performance of the WIMS (Wireless Integrated MicroSystems microcontroller implemented in 180- and 65-nm processes and upon simulations of this microcontroller implemented in a 32-nm process. The results demonstrate that scratchpad memories will continue to improve the power dissipation of many applications, given the leakage anticipated in the foreseeable future.

    Full Text Available The problem of energy saving becomes one of the most important in power engineering. It is caused by exhaustion of world reserves in hydrocarbon fuel, such as gas, oil and coal representing sources of traditional heat supply. Conventional sources have essential shortcomings: low power, ecological and economic efficiencies, that can be eliminated by using alternative methods of power supply, like the considered one: low-temperature natural heat of ground waters of on the basis of heat pump installations application. The heat supply system considered provides an effective use of two stages heat pump installation operating as heat source at ground waters during the lowest ambient temperature period. Proposed is a calculation method of heat pump installations on the basis of groundwater energy. Calculated are the values of electric energy consumption by the compressors’ drive, and the heat supply system transformation coefficient µ for a low-potential source of heat from ground waters allowing to estimate high efficiency of two stages heat pump installations.

  2. MUXER—A New Equipment for Energy Saving in Ethernet

    2017-11-01

    Full Text Available Nowadays, the rapidly increasing energy consumption of communication equipment is an economic and environmental problem that needs to be addressed. Small Local Area Networks (LAN switches in the US alone consume about 8 TWh per year that corresponds to hundreds of millions of US dollars in electricity. A main reason is communication equipment, due to the fact that, Ethernet switches have to active all days even in low-traffic time. There are many approaches to make the switches sensitive with the different traffic load environment, but they have to put some changes to current Ethernet that cause the incompatibility issues. This paper proposes a new device called Modified Multiplexer (MUXER, which can control the power functions of switches without modifying the current Ethernet protocol. The MUXER devices are put before the switches in the network, which provide some functions to transfer incoming Media Access Control (MAC data frames to the corresponding switches managed by MUXERs. By using the proposed device, the wasted energies in the network can be reduced, especially in the specified low-traffic time. We describe the result of numerical analysis and compare detail power consumption data between a normal and a network where MUXERs are installed. In this work, the explained result shows that if a network administrator can estimate the number of MUXER needed for a particular network and install accordingly, our device can provides a significant energy saving.

In order to maintain them in working condition, especially in winter period, it takes significant amount of thermal energy. Task of heat loss substantial decrease in open swimming pools is considered in the article (on DNURT example. Methodology. The method of determining the mass and heat loss on the basis of criteria equations of heat and mass transfer theory is used. Findings. Calculations of the actual DNURT pool heat loss for different seasons, as for natural convection both for air forced motion above the free water surface are performed. It is shown that for the adiabatic evaporation conditions of water from the pool in winter during blow-off with wind the heat loss can be up to 2 kW/m2 on surface. To reduce these losses it is offered to cover water surface in a pool with a special material with low thermal conductivity on the basis of porous polyethylene during the time when the pool is not used for other purposes. It is shown that the implementation of these standards will reduce the actual heat loss, at least 5-6 times. Originality. The solution of important environmental and energy problem thanks to reducing heat losses by the pool in different times of a year and correspondingly lower emissions of power generating enterprises. Practical value. It is shown that the coating surface of the pool with poorly heat-conducting and easy to install coating will let, at a minimum, to reduce the actual heat loss on 5-6 times and reduce the emissions of power plants generating energy for pool heating.

    Due to the high energy consumption of communication, energy saving of data centers must be enforced. But the lack of evaluation mechanisms has restrained the process on energy saving construction of data centers. In this paper, energy saving evaluation index system of data centers was constructed on the basis of clarifying the influence factors. Based on the evaluation index system, analytical hierarchy process was used to determine the weights of the evaluation indexes. Subsequently, a three-grade fuzzy comprehensive evaluation model was constructed to evaluate the energy saving system of data centers.

    2007-01-01

    Trigeneration or combined heat, cooling and power (CHCP) is becoming an increasingly important energy option, particularly on a small-scale basis (below 1 MW e ), with several alternatives nowadays available for the cooling power production and the coupling to cogeneration systems. This paper deals with the introduction of a suitable framework for assessing the energy saving performance of trigeneration alternatives, orientated towards energy planning studies and the development of regulatory policies. In particular, a new generalized performance indicator-the trigeneration primary energy saving (TPES)-is introduced and discussed, with the aim of effectively evaluating the primary energy savings from different CHCP alternatives. The potential of the TPES indicator is illustrated through specific analyses run over different combinations of trigeneration equipment, providing numerical examples based on time-domain simulations to illustrate the dependence of the energy saving characteristics on the CHCP system configurations and equipment, as well as on the loading levels. In addition, the key aspect of adequately establishing the reference efficiencies for the conventional separate production of electrical, thermal and cooling power is addressed in detail. This aspect affects both equipment selection and potential profitability of the considered solutions under the outlook of receiving financial incentives

    2011-05-23

    Residential thermostats play a key role in controlling heating and cooling systems. Occupants often find the controls of programmable thermostats confusing, sometimes leading to higher heating consumption than when the buildings are controlled manually. A high degree of usability is vital to a programmable thermostat's effectiveness because, unlike a more efficient heating system, occupants must engage in specific actions after installation to obtain energy savings. We developed a procedure for measuring the usability of thermostats and tested this methodology with 31 subjects on five thermostats. The procedure requires first identifying representative tasks associated with the device and then testing the subjects ability to accomplish those tasks. The procedure was able to demonstrate the subjects wide ability to accomplish tasks and the influence of a device's usability on success rates. A metric based on the time to accomplish the tasks and the fraction of subjects actually completing the tasks captured the key aspects of each thermostat's usability. The procedure was recently adopted by the Energy Star Program for its thermostat specification. The approach appears suitable for quantifying usability of controls in other products, such as heat pump water heaters and commercial lighting.

    2013-11-01

    We propose and demonstrate an improved survivable and energy-saving WDM-PON with colorless ONUs. It incorporates both energy-saving and self-healing operations. A simple effective energy-saving scheme is proposed by including an energy-saving control unit in the OLT and a control unit at each ONU. The energy-saving scheme realizes both dozing and sleep (offline) modes, which greatly improves the energy-saving efficiency for WDM-PONs. An intelligent protection switching scheme is designed in the OLT, which can distinguish if an ONU is in dozing/sleep (offline) state or a fiber is faulty. Moreover, by monitoring the optical power of each channel on both working and protection paths, the OLT can know the connection status of every fiber path, thus facilitating an effective protection switching and a faster failure recovery. The improved WDM-PON architecture not only significantly reduces energy consumption, but also performs self-healing operation in practical operation scenarios. The scheme feasibility is experimentally verified with 10 Gbit/s downstream and 1.25 Gbit/s upstream transmissions. We also examine the energy-saving efficiency of our proposed energy-saving scheme by simulation, which reveals that energy saving mainly arises from the dozing mode, not from the sleep mode when the ONU is in the online state.

    Analysing household energy-saving behaviours is crucial to improve energy consumption predictions and energy policy making. How should we quantitatively measure them? What are their determinants? This study explores the main factors influencing residential energy-saving behaviours based on a bottom-up multivariate statistical approach using data from the recent French PHEBUS survey. Firstly, we assess energy-saving behaviours on a one-dimension scale using IRT. Secondly, we use linear regression with an innovative variable selection method via adaptive lasso to tease out the effects of both macro and micro factors on the behavioural score. The results highlight the impact of five main attributes incentivizing energy-saving behaviours based on cross-variable analyses: energy price, household income, education level, age of head of household and dwelling energy performance. In addition, our results suggest that the analysis of the inverted U-shape impact of age enables the expansion of the energy consumption life cycle theory to energy-saving behaviours. - Highlights: • We examine the main factors influencing residential energy-saving behaviours. • We use data from the recent French PHEBUS survey. • We use IRT to assess energy-saving behaviours on a one-dimension scale. • We use linear regression with an innovative variable selection method via adaptive lasso. • We highlight the impact of five main attributes incentivizing energy-saving behaviours.

    At the Research Station of Royal Veterinary and Agricultural University, Copenhagen, Denmark, investigation concerning cultivation and exploitation of field crops for production of fuels was carried out during the period 1986-1989. High yielding crops, such as sugar beet - BETA VULGARIS, jerusalem artichoke - HELIANTHUS TUBEROSUS, rhubarb - RHEUM RHAPONTICUM, and comfrey - SYMPHYTUM ASPERUM, were grown experimentally in the field. Different cultivation methods for the crops were used and evaluated. Simultaneously with the field experiment, laboratory investigation was carried out to determine the energy potential of different products and by-products from the crops processes, such as alcoholic and methanogenic fermantation. Production expenses for the crops were determined, and cost of the fuels was estimated. The experimental results show that beet is a superior crop for the climatic conditions of Northern Europe. In the season 1986, yields exceeded 20 t TS/ha in the form of roots and tops, where achieved. A combined exploitation of beet roots and tops via alcoholic and methanogenic fermantation gave a gross energy corresponding to 80 hl OE/ha/yr. Using methanogenic fermentation exclusively, from ensiled beet roots and tops, gross energy yield corresponding to 85 hl IE/ha/yr, was achieved. The cost of energy in the form of alcohol from beet roots was estimated to be 5.17 DKK/1 OE (0.64 ECU/l OE). The cost of energy in the form of methane from ensiled beet tops, was estimated to be 2.68 DKK/l OE (0.33 ECU/l OE). At the present time, methane produced on the basis of ensiled beet roots and tops appears to be competitive with fossil fuels. Irrespective of the cost, however, the possibility of producing clean energy from field crops remains of interest for the future. (author) 27 refs.

    Retrocommissioning (RCx) is a systematic process for optimizing energy performance in existing buildings. It specifically focuses on improving the control of energy-using equipment (e.g., heating, ventilation, and air conditioning [HVAC] equipment and lighting) and typically does not involve equipment replacement. Field results have shown proper RCx can achieve energy savings ranging from 5 percent to 20 percent, with a typical payback of two years or less (Thorne 2003). The method presented in this protocol provides direction regarding: (1) how to account for each measure's specific characteristics and (2) how to choose the most appropriate savings verification approach.

    Background. Policy makers and program managers need to better understand consumers’ perceptions of their energy use and savings to design effective strategies for promoting energy savings. Methods. We reviewed 14 studies from the emerging interdisciplinary literature examining consumers’ perceptions electricity use by specific appliances, and potential savings. Results. We find that: (1) electricity use is often overestimated for low-energy consuming appliances, and underestimated for high-energy consuming appliances; (2) curtailment strategies are typically preferred over energy efficiency strategies; (3) consumers lack information about how much electricity can be saved through specific strategies; (4) consumers use heuristics for assessing the electricity use of specific appliances, with some indication that more accurate judgments are made among consumers with higher numeracy and stronger pro-environmental attitudes. However, design differences between studies, such as variations in reference points, reporting units and assessed time periods, may affect consumers’ reported perceptions. Moreover, studies differ with regard to whether accuracy of perceptions was evaluated through comparisons with general estimates of actual use, self-reported use, household-level meter readings, or real-time smart meter readings. Conclusion. Although emerging findings are promising, systematic variations in the measurement of perceived and actual electricity use are potential cause for concern. We propose avenues for future research, so as to better understand, and possibly inform, consumers’ perceptions of their electricity use. Ultimately, this literature will have implications for the design of effective electricity feedback for consumers, and related policies.

    The objective of this work was to determine the realization rate of energy and cost savings from the Department of Energy’s Energy Savings Performance Contract (ESPC) program based on information reported by the energy services companies (ESCOs) that are carrying out ESPC projects at federal sites. Information was extracted from 151 Measurement and Verification (M&V) reports to determine reported, estimated, and guaranteed cost savings and reported and estimated energy savings for the previous contract year. Because the quality of the reports varied, it was not possible to determine all of these parameters for each project.

    In Asian developing countries, energy saving has become a crucial issue in sustainable development. However, in countries that possess weak government regulations and market mechanisms, industries are expected to save energy voluntarily. Therefore, corporate social responsibility (CSR) can serve as an important incentive to encourage companies to take voluntary actions. In this paper, we analyze CSR recognition and energy-saving actions taken by companies located in two Asian cities. The results of a questionnaire survey revealed that a positive relation exists between CSR recognition and energy saving. In developing countries, CSR develops based on concerns expressed by local cultures and communities. This indicates that the positive relationships that exist between CSR and energy-saving actions reflect the social norms of these communities. The results suggest that policies that encourage companies to enhance their CSR activities in society can serve as effective incentives to encourage energy-saving actions. - Highlights: • In Asian cities, energy saving has become a crucial issue in sustainable development. • CSR can serve as an important incentive to take voluntary energy saving actions. • The survey revealed a positive relation between CSR and energy saving. • The policies enhancing their CSR activities in society can serve as effective incentives

    This paper provides an analysis of the current energy usage (net energy and final energy by fuels) and associated carbon dioxide (CO 2 ) emissions of the Swedish residential building stock, which includes single-family dwellings and multi-family dwellings. Twelve energy saving measures (ESMs) are assessed using a bottom–up modeling methodology, in which the Swedish residential stock is represented by a sample of 1400 buildings (based on data from the year 2005). Application of the ESMs studied gives a maximum technical reduction potential in energy demand of 53%, corresponding to a 63% reduction in CO 2 emissions. Although application of the investigated ESMs would reduce CO 2 emissions, the measures that reduce electricity consumption for lighting and appliances (LA) will increase CO 2 emissions, since the saved electricity production is less CO 2 -intensive than the fuel mix used for the increased space heating required to make up for the loss in indirect heating obtained from LA. - Highlights: ► Analysis of year 2005energy use and CO2 emissions of Swedish residential buildings. ► Includes all single-family dwellings and multi-family dwellings. ► Bottom–up modeling of building stock represented by 1400 buildings. ► Technical effects of 12 energy saving measures are assessed. ► Energy demand can be reduced by53% and associated CO 2 emissions by 63%

    This reports presents an analysis of energy efficiency trends in Germany on the basis of energy efficiency indicators extracted from the ODYSSEE data base, maintained and updated in the framework of the SAVE programme. This analysis focuses on the period 1990-2000. The year 1990 could however not be considered for all indicators, because most of the economic and some energy consumption data for Germany are only available since 1991. The analysis also examines the policies and measures implemented in the field of energy efficiency, with a focus on the latest years until February 2002. All these measures are extracted from the MURE data base also updated within the SAVE programme. The report starts with a review on data collection and the recent trends in the general context of energy efficiency, i. e. economic and energy consumption development, energy and environmental policy and energy price trends (Chapter 2). Afterwards, the energy efficiency trends are described both at the level of the whole economy and at sectoral level (Chapter 3). In Chapter 4 the development in one sector - transport - is described more detailed. For the other sectors (industry, residential, tertiary) Annex 2 presents a selection of commented graphs that show the trends for the main indicators. An overview of the most important measures in the field of energy efficiency policy in the end-use sectors in Germany is given in Annex 1. A more detailed description of the most recent measures is presented in Annex 3. (orig.)

    In this research, the willingness of households to adopt different energy-saving behavior has been analyzed, and factors influencing energy-saving behavior in Jiangsu Province, China, have been examined. The study builds on a broad and practical conceptual framework that embraces three types of energy-saving behavior and four dimensions of influencing factors, including socio-demographics, energy-saving awareness, behavioral ability, and situational factors. The empirical results are based on an Internet survey that was sent out to 638 households. The results indicate that socio-demographic characteristics, including age, gender, income level, household structure, and educational background, are all important factors influencing energy-saving behavior. At present, respondents adopt the usage-reduction type of behavior more often than the other two types, which require a greater capacity to pay for energy-efficient products and a higher level of energy-saving awareness. Situational factors have significant positive moderating effects when the variables of behavioral ability and energy-saving awareness act on energy-saving behavior. In addition, the results also show that spatial differences exist among the three regions of Jiangsu Province. Finally, some implications of these results for the design of future incentive policies and measures to encourage energy-saving behavior are presented. -- Highlights: •A broad and practical conceptual framework of energy-saving behaviors is built. •Socio-demographic characteristics are determinants of energy-saving behavior. •Respondents adopt the usage-reduction type more often than the other two types. •Situational factors have positive moderating effects on the other two variables. •Spatial differences exist among the three regions of Jiangsu Province

    This Technical Support Document describes the process and methodology for the development of the Advanced Energy Design Guide for Large Hospitals: Achieving 50% Energy Savings Toward a Net Zero Energy Building (AEDG-LH) ASHRAE et al. (2011b). The AEDG-LH is intended to provide recommendations for achieving 50% whole-building energy savings in large hospitals over levels achieved by following Standard 90.1-2004. The AEDG-LH was created for a 'standard' mid- to large-size hospital, typically at least 100,000 ft2, but the strategies apply to all sizes and classifications of new construction hospital buildings. Its primary focus is new construction, but recommendations may be applicable to facilities undergoing total renovation, and in part to many other hospital renovation, addition, remodeling, and modernization projects (including changes to one or more systems in existing buildings).

    The US Department of Energy’s most recent commercial energy code compliance evaluation efforts focused on determining a percent compliance rating for states to help them meet requirements under the American Recovery and Reinvestment Act (ARRA) of 2009. That approach included a checklist of code requirements, each of which was graded pass or fail. Percent compliance for any given building was simply the percent of individual requirements that passed. With its binary approach to compliance determination, the previous methodology failed to answer some important questions. In particular, how much energy cost could be saved by better compliance with the commercial energy code and what are the relative priorities of code requirements from an energy cost savings perspective? This paper explores an analytical approach and pilot study using a single building type and climate zone to answer those questions.

    Energy consumption is a factor influencing the cost of Electrochemical Chloride Extraction (ECE) in concrete. The aims of this work were to investigate the possibility for energy saving when using a pulsed electric field during ECE and the effect of the pulsed current on removal of chloride. Four...... experiments with artificially polluted concrete under same charge transfer were conducted. Results showed that the energy consumption was decreased 15% by pulse current in experiments with 0.2 mA/cm2 current density, which was higher than that of 0.1 mA/cm2 experiments with a decrease of 9.6%. When comparing...... the voltage drop at different parts of the experimental cells, it was found that the voltage drop of the area across the concrete was the major contributor to energy consumption, and results indicated that the pulse current could decrease the voltage drop of this part by re-distribution of ions in pore fluid...

    End-use energy efficiency is increasingly being relied upon as a resource for meeting electricity and natural gas utility system needs within the United States. There is a direct connection between the maturation of energy efficiency as a resource and the need for consistent, high-quality data and reporting of efficiency program costs and impacts. To support this effort, LBNL initiated the Cost of Saved Energy Project (CSE Project) and created a Demand-Side Management (DSM) Program Impacts Database to provide a resource for policy makers, regulators, and the efficiency industry as a whole. This study is the first technical report of the LBNL CSE Project and provides an overview of the project scope, approach, and initial findings, including: • Providing a proof of concept that the program-level cost and savings data can be collected, organized, and analyzed in a systematic fashion; • Presenting initial program, sector, and portfolio level results for the program administrator CSE for a recent time period (2009-2011); and • Encouraging state and regional entities to establish common reporting definitions and formats that would make the collection and comparison of CSE data more reliable. The LBNL DSM Program Impacts Database includes the program results reported to state regulators by more than 100 program administrators in 31 states, primarily for the years 2009–2011. In total, we have compiled cost and energy savings data on more than 1,700 programs over one or more program-years for a total of more than 4,000 program-years’ worth of data, providing a rich dataset for analyses. We use the information to report costs-per-unit of electricity and natural gas savings for utility customer-funded, end-use energy efficiency programs. The program administrator CSE values are presented at national, state, and regional levels by market sector (e.g., commercial, industrial, residential) and by program type (e.g., residential whole home programs, commercial new

    Sustainability is one of the major aims in greenhouse horticulture. According to agreements between the Dutch grower association and the government, energy consumption and the use of chemical biocides have to be reduced. More advanced greenhouse technique is being developed to reach the target to decrease the energy efficiency-index by 65% between 1980 and 2010. However, this could also be achieved with existing technology by using more advanced climate regimes. The present thesis aimed at that, through designing and analysing climate regimes while employing existing climate control possibilities. Theoretical temperature and humidity regimes were designed to decrease energy consumption and a photosynthesis maximisation procedure was implemented to maximise growth. The basis for a crop gross photosynthesis model for control purposes was created. Crop photosynthesis models were evaluated at conditions expected to occur with more sustainable climate regimes. It was shown with experimental evidence that theoretical assumptions on the temperature - CO2 effects in a crop that are based on theoretically models scaling up leaf photosynthesis to the crop level are valid and that simplified existing models could be applied up to 28C. With higher temperatures new designs are needed and this can probably be achieved with an improved stomata-resistance model. The well known temperature integration principle was modified with two nested time-frames (24-hour and six days) and a temperature dose-response function. In a year round tomato cultivation, energy consumption was predicted to decrease with up to 9 % compared to regular temperature integration. The potential for energy saving with temperature integration is limited by humidity control when as usual fixed set points are maintained, because it counteracts temperature integration. Vents open at lower temperatures and heating is switched on at higher temperatures than required for optimal effects of temperature integration. A

    Obligations to save energy differentiate, among other features, by obliged parties. These are obligations on energy suppliers and energy end-users. Supplier obligations have been introduced in North America, Europe and Australia. Under supplier obligations energy suppliers have to comply with mandatory energy saving targets and thus they implement (directly or via third parties) energy efficiency projects on their clients’ premises, or they decide to trade certified project savings if this option is envisaged by their obligation scheme. In several emerging schemes such as the UK Carbon Reduction Commitment (CRC) Energy Efficiency Scheme, the Tokyo Emission Trading Scheme or the Perform Achieve and Trade (PAT) Scheme in India, the obligation to reduce energy consumption is placed on large end-users directly and end-users are allowed to trade emissions allowances or energy saving certificates. The paper starts with presenting these two conceptually different ways for introducing energy saving obligations. Then it analyses advantages and disadvantages of end-users obligations compared to suppliers obligations. The preliminary conclusion of the paper is that supplier obligations seem to be well-suited for the residential sector, but end-user saving obligations may offer advantages when it comes to the industrial and commercial sectors. - Highlights: • We present different ways for introducing energy saving obligations. • We analyse energy end-users obligations vs. supplier obligations. • Supplier obligations seem to be well-suited for the residential sector. • End-user obligations offer advantages in the industrial and commercial sectors

    Energy saving measures being studied and implemented in Japan to reduce marine diesel fuel consumption are described. Lower ship speeds, bulb bows, better surface paint, a reaction ladder, low speed diesel engines with long stroke cylinders and superchargers are being tried. Large, low speed, controllable pitch propellers, digital engine control, and waste heat recovery with Rankine cycle generators are other methods under investigation. Blade cooling and reheating are being introduced, and a set of computer controlled maneuverable metal sails undergoing sea tests on a commercial tanker as a fuel saving technique have displayed a 20% fuel savings in tests. A windmill is under design for ship propulsion, involving several vertical airfoils revolving around a vertical axis of rotation. Direct connection to a propeller is being considered, noting that operations to windward would be possible.

    Full Text Available Energy saving and greenhouse gas (GHG emission reduction policies at local level need to be investigated and new tools for climate change mitigation are necessary seeking to achieve GHG emission targets in Lithuania. Most Lithuanian municipalities have signed Covenant of Mayors and have prepared local energy action plans. However, all these plans include just energy saving measures on supply side and renovation of buildings. Nevertheless, the significant energy savings and GHG emission reductions can be achieved through behavioural changes. The aim of the paper is to apply community based social marketing approach in assessment of achievable energy saving and GHG emission reduction targets set by local energy action plans. The paper presents the results of case study implemented in Kaunas region municipality. The case study was conducted by creating focus groups and applying two scenarios: baseline or doing nothing and climate change mitigation scenario including intervention measures. The results of case study revealed that the total energy consumption reduction target set in Sustainable energy development strategy of Kaunas region county - 11% - can be achieved by combining results of energy consumption reduction in both focus groups. The survey conducted after study finalization revealed that respondents were provided with a lot of additional knowledge during the study and achieved real money savings. The major barriers of energy savings in households are related with the lack of information on energy savings and GHG emission reduction.

    Modern access networks are constructed widely by passive optical networks (PONs) to meet the growing bandwidth demand. However, higher bandwidth means more energy consumption. To save energy, a few research works propose the dual-mode energy saving mechanism that allows the ONU to operate between active and sleep modes periodically. However, such dual-mode energy saving design may induce unnecessary power consumption or packet delay increase in the case where only downstream data exist for most of the time. In this paper, we propose a new tri-mode energy saving scheme for Ethernet PON (EPON). The new tri-mode energy saving design, combining the dual-mode saving mechanism with the doze mode, allows the ONU to switch among these three modes alternatively. In the doze mode, the ONU may receive downstream data while keeping its transmitter close. Such scenario is often observed for real time video downstream transmission. Furthermore, the low packet delay of high priority upstream data can be attained through the use of early wake-up mechanism employed in both energy saving modes. The energy saving and system efficiency can thus be achieved jointly while maintaining the differentiated QoS for data with various priorities. Performance results via simulation have demonstrated the effectiveness of such mechanism.

    Highlights: • We provide a systematic approach to quantify the impact of factors on energy usage. • We study setpoints, deadbands, building size, construction, occupancy, and climate. • We derive the HVAC optimal control parameters with respect to dynamic factors. • We present quantification of optimal setpoints and deadbands energy usages. • Daily optimal setpoints based on outside temperature improves energy efficiency. - Abstract: This paper provides a systematic approach for quantifying the influence of building size, construction category, climate, occupancy schedule, setpoint, and deadband on HVAC energy consumption in office buildings. Simulating the DOE reference office buildings of three sizes and three construction categories in all United States climate zones, using the EnergyPlus, we conducted several N-way ANOVA analyses to study the interrelationships between setpoints, deadbands and several building related and environment related factors. In summary, daily optimal deadband selection of 0, 1, 2, 4, 5, and 6 K would result in an average energy savings of −70.0%, −34.9%, −13.7%, 9.6%, 16.4%, and 21.2%, respectively, compared to baseline deadline of 3 K. Selecting the daily optimal setpoint in the range of 22.5 ± 1 °C, 22.5 ± 2 °C, and 22.5 ± 3 °C would result in an average savings of 7.5%, 12.7%, and 16.4%, respectively, compared to the baseline setpoint of 22.5 °C. Additionally, we found that when the outdoor temperature is within −20 to 30 °C, the optimal setpoint depends on the building size. We also observed a range of outdoor temperatures (e.g., 9–14 °C for small buildings and 8–11 °C for medium buildings) where the setpoint selection would only slightly influence the energy consumption. However, the choice of setpoints becomes very influential (up to 30% of energy savings) where the outdoor temperatures are slightly outside the mentioned ranges on either direction. The potential savings from selecting daily optimal

    Since China became the second largest energy consumer and carbon dioxide emitter, the problem of energy consumption and environmental pollution has drawn the world's attention. Meanwhile, Chinese government has put high emphasis on the problem. One project of energy saving initiated by Chinese government has been put into practice. However, many difficulties need to be dealt with to meet the expected aim of social development. The objective of this article is to investigate the interactions among the major barriers which prevent the practice of energy saving in China. Obviously, a clear definition of relationships among the barriers to energy saving helps top leaders make relevant decisions to solve the problem of economic sustainability, energy security and environment pollution in the future. To date, studies specifying energy-saving barriers have often focused on analyzing these barriers separately. As a result, a holistic view in understanding the barriers to energy-saving project is lacking. Interpretive structural modeling (ISM) is utilized to summarize the critical barriers hindering the project of energy saving in China and to explain the interrelationships among them. Suggestions for energy-saving practice and future research are provided. (author)

    This study was conducted by the Pacific Northwest National Laboratory (PNNL) in support of the stretch energy code development led by the New York State Energy Research and Development Authority (NYSERDA). In 2017 NYSERDA developed its 2016 Stretch Code Supplement to the 2016 New York State Energy Conservation Construction Code (hereinafter referred to as “NYStretch-Energy”). NYStretch-Energy is intended as a model energy code for statewide voluntary adoption that anticipates other code advancements culminating in the goal of a statewide Net Zero Energy Code by 2028. Since then, NYSERDA continues to develop the NYStretch-Energy Code 2018 edition. To support the effort, PNNL conducted energy simulation analysis to quantify the energy savings of proposed commercial provisions of the NYStretch-Energy Code (2018) in New York. The focus of this project is the 20% improvement over existing commercial model energy codes. A key requirement of the proposed stretch code is that it be ‘adoptable’ as an energy code, meaning that it must align with current code scope and limitations, and primarily impact building components that are currently regulated by local building departments. It is largely limited to prescriptive measures, which are what most building departments and design projects are most familiar with. This report describes a set of energy-efficiency measures (EEMs) that demonstrate 20% energy savings over ANSI/ASHRAE/IES Standard 90.1-2013 (ASHRAE 2013) across a broad range of commercial building types and all three climate zones in New York. In collaboration with New Building Institute, the EEMs were developed from national model codes and standards, high-performance building codes and standards, regional energy codes, and measures being proposed as part of the on-going code development process. PNNL analyzed these measures using whole building energy models for selected prototype commercial buildings and multifamily buildings representing buildings in New

    The Energy sector is the largest contributor to GHG emission in Mongolia. The Energy sector emits 54 percent of CO2 and 4 percent of methane. All emissions of other greenhouse gases are accounted from energy related activities. The activities in this sector include coal production, fuel combustion, and biomass combustion at the thermal power stations and in private houses (stoves) for heating purposes. This paper presents some important Demand-side options considered for mitigation of CO2 emissions from energy sector such as Energy Conservation in Industrial Sector and in Buildings. Changes in energy policies and programmes in the Mongolian situation that promote more efficient and sustainable practices are presented in the paper. These energy saving measures will not only help reduce greenhouse gas emissions, but will also promote economic development and alleviate other environmental problems.

    most common facing materials of natural origin include wooden facades. Demand for such kind of structures in contemporary architecture is explained by wide possibilities of architectural and artistic facades. Facade decor made of wood is various, it tends to be unusual, with exclusive forms, eliminating unnecessary luxury. Valuable wood panels, board with logs imitation, block house, facade boards (planken, the wood tile (shingle, etc. can be used in decoration. A large number of wooden facing materials allow to create wooden facades of different styles, and the texture and wood shades form a harmonious environment. Among the various methods of using wooden decor the most common technique is outplaying of wood texture. Wood is treated with special impregnation to give effect of the natural aging, wood is also tinted, creating a color contrast of house planes, and then is coloured, imitating the texture of precious wood. Wooden facade decor fully solves not only the problem of architectural expressiveness of structures, but also the problem of energy saving, which is especially important in the context of the global crisis. The unique capabilities of the tree, its ability to be in harmony with other materials form a comfortable environment, providing a favorable psychological impact.

    1992-02-01

    The Portland Energy Office provided operation and maintenance (O M) training to the operators of boiler heating systems for ten low-income apartment complexes in the Fall of 1990. This study tracked energy usage before and after O M training to see if savings occurred. Training was provided on both weatherized and non-weatherized apartments to find out if weatherization impacted the amount of O M savings to be obtained. Also, energy savings from the O M training and building shell weatherization are compared. The O M training averaged about four hours per building. Content was adjusted at each site to match needs of the boiler and operator. The Energy Office also provided a boiler tune-up by a service technician. The training stressed low-cost and no-cost measures which operators could either do themselves or hire service help to implement. It also emphasized boiler safety. Nine of the ten apartment complexes in the study used less energy per heating degree-day after the O M help. Average savings were 10%. Four apartments chosen randomly as controls had negative savings; they used slightly more energy during the same post-O M time frame. Weatherized and unweatherized apartments showed similar savings after the O M help, 10% and 11% percent respectively. Savings from weatherization of six of the apartments in the winter of 1988--1989 were also measured. A low average of only 4% was observed, reflecting negative savings in two buildings.

    The Energy Policy Act of 2005 (Pub. L. No. 109-58; EPAct 2005) amended the Uniform Time Act of 1966 (Pub. L. No. 89-387) to increase the portion of the year that is subject to Daylight Saving Time. (15 U.S.C. 260a note) EPAct 2005 extended the duration of Daylight Saving Time in the spring by changing its start date from the first Sunday in April to the second Sunday in March, and in the fall by changing its end date from the last Sunday in October to the first Sunday in November. (15 U.S.C. 260a note) EPAct 2005 also called for the Department of Energy to evaluate the impact of Extended Daylight Saving Time on energy consumption in the United States and to submit a report to Congress. (15 U.S.C. 260a note) This report presents the results of impacts of Extended Daylight Saving Time on the national energy consumption in the United States. The key findings are: (1) The total electricity savings of Extended Daylight Saving Time were about 1.3 Tera Watt-hour (TWh). This corresponds to 0.5 percent per each day of Extended Daylight Saving Time, or 0.03 percent of electricity consumption over the year. In reference, the total 2007 electricity consumption in the United States was 3,900 TWh. (2) In terms of national primary energy consumption, the electricity savings translate to a reduction of 17 Trillion Btu (TBtu) over the spring and fall Extended Daylight Saving Time periods, or roughly 0.02 percent of total U.S. energy consumption during 2007 of 101,000 TBtu. (3) During Extended Daylight Saving Time, electricity savings generally occurred over a three- to five-hour period in the evening with small increases in usage during the early-morning hours. On a daily percentage basis, electricity savings were slightly greater during the March (spring) extension of Extended Daylight Saving Time than the November (fall) extension. On a regional basis, some southern portions of the United States exhibited slightly smaller impacts of Extended Daylight Saving Time on energy savings

    . A lowered district heating demand and thereby lowered CHP-bound electricity generation would appear to increase the possibility of integration wind power but due to the ancillary services supplied by CHP plants, the situation is in fact the opposite. Heat savings may not be technically feasible......, if a certain production is required regardless of whether over-all electricity generation is sufficient. This article analyses this and although heat savings do have a negative impact on the amount of wind power the system may integrate a given moment in certain cases, associated fuel savings are notable......In Denmark, the integration of wind power is affected by a large amount of cogeneration of heat and power. With ancillary services supplied by large-scale condensation and combined heat and power (CHP) plants, a certain degree of large-scale generation is required regardless of momentary wind input...

    The energy screens in two greenhouses, one clad with double acrylic and one with single glass, were controlled by an energy balance model. The parameters in the model were heat transmission coefficients, air temperature in the greenhouse and outdoors, irradiance and a single constant for the solar energy efficiency. The energy consumption, screen movements and daily light integral were compared with a glass greenhouse in which the energy screens were controlled by irradiance. In the greenhouse with light-controlled screens the set point for opening and closing of the screens was 5 Wm-2. The energy-saving screens controlled by the energy balance model opened later and closed earlier than in the greenhouse with light-controlled screens. When using the energy balance model the energy saving was 14% for the glass greenhouse and 41% for the double acrylic greenhouse compared with the glass greenhouse with light-controlled screens. The air temperature was on average similar in the three greenhouses, but when the screens were controlled by energy balance the daily light integral was approximately 10% lower and the number of hours the screens were closed was prolonged with 35% for the glass-covered greenhouse and 25% for the double acrylic-covered greenhouse compared with the greenhouse with light-controlled screens. Energy peaks in connection with operation of the screens were not reduced. During the experiment Begonia elatior, Dendranthema grandiflora (Chrysanthemum), Hedera helix, Helianthus annuus, Gerbera jamesonii and Kalanchoe blossfeldiana were grown in the greenhouses. There was a trend in prolongation of the production time when the plants were grown in the glass greenhouse with energy balance control of the screens. A lower number of flowers or inflorescences were observed for some of the plant species produced in the greenhouses with energy balance-controlled screens

    California s major energy utilities and the California Energy Commission (CEC) are seeking to allocate capital that yields the greatest return on investment for energy infrastructure that meets any part of the need for reliable supplies of energy. The utilities are keenly interested in knowing the amount of electrical energy savings that would occur if cool roof color materials are adopted in the building market. To meet this need the Oak Ridge National Laboratory and the Lawrence Berkeley National Laboratory (LBNL) have been collaborating on a Public Interest Energy Research (PIER) project to develop an industry-consensus energy-savings calculator. The task was coordinated with an ongoing effort supported by the DOE to develop one calculator to achieve both the DOE and the EPA objectives for deployment of cool roof products. Recent emphasis on domestic building energy use has made the work a top priority by the Department of Energy s (DOE) Building Technologies Program. The Roof Savings Calculator (RSC) tool is designed to help building owners, manufacturers, distributors, contractors and practitioners easily run complex simulations. The latest web technologies and usability design were employed to provide an easy input interface to an annual simulation of hour-by-hour, whole-building performance using the world-class simulation tools DOE-2.1E and AtticSim. Building defaults were assigned based on the best available statistical evidence and can provide energy and cost savings after the user selects nothing more than the building location. A key goal for the tool is to promote the energy benefits of cool color tile, metal and asphalt shingle roof products and other energy saving systems. The RSC tool focuses on applications for the roof and attic; however, the code conducts a whole building simulation that puts the energy and heat flows of the roof and attic into the perspective of the whole house. An annual simulation runs in about 30 sec. In addition to cool

    It is easy to measure energy consumption with a power meter. However, energy savings cannot be directly computed by the powers measured using existing power meter technologies, since the power consumption only reflects parts of the real energy flows. The International Performance Measurement and Verification Protocol (IPMVP) was proposed by the Efficiency Valuation Organization (EVO) to quantify energy savings using four different methodologies of A, B, C and D. Although energy savings can be estimated following the IPMVP, there are limitations on its practical implementation. Moreover, the data processing methods of the four IPMVP alternatives use multiple sensors (thermometer, hygrometer, Occupant information) and power meter readings to simulate all facilities, in order to determine an energy usage benchmark and the energy savings. This study proposes a simple sensor platform to measure energy savings. Using usually the Electronic Product Code (EPC) global standard, an architecture framework for an information system is constructed that integrates sensors data, power meter readings and occupancy conditions. The proposed sensor platform is used to monitor a building with a newly built vertical garden system (VGS). A VGS shields solar radiation and saves on energy that would be expended on air-conditioning. With this platform, the amount of energy saved in the whole facility is measured and reported in real-time. The data are compared with those obtained from detailed measurement and verification (M&V) processes. The discrepancy is less than 1.565%. Using measurements from the proposed sensor platform, the energy savings for the entire facility are quantified, with a resolution of ±1.2%. The VGS gives an 8.483% daily electricity saving for the building. Thus, the results show that the simple sensor platform proposed by this study is more widely applicable than the four complicated IPMVP alternatives and the VGS is an effective tool in reducing the carbon

    Recent years have seen increasing public interest in issues related to energy saving and concern for the environment. It is important to highlight the work of public institutions in this respect. This was the motive that led the University of Valencia to finance a pilot project with the objective of studying useful initiatives for optimising energy consumption in accordance with the institution's needs as well as the incorporation of innovative and more efficient technologies. The approach was to consider various aspects ranging from the analysis of the current energy consumption and the state of the installations, through the substitution of some energy inefficient components, to the study of the possible installation of a photovoltaic solar powered electricity generation station connected to the network. Also purely technical questions on economic efficiency should not be forgotten as this could lead to a reduction in energy consumption and the optimisation of the current energy consuming equipment, since generally, it is this question that limits the possible energy saving actions.

    Highlights: • Energy management approach of hybrid vehicles using traffic preview information. • Vehicle velocity profile and fuel consumption are optimized at the same time. • It is proved that a further energy saving is achieved by the proposed approach. • The proposed approach is useful especially for autonomous hybrid vehicles. - Abstract: The traffic preview information is very helpful for hybrid vehicles when distributing the power requirement of the vehicle to power sources and when determining the next driving route of the vehicle. In this research, an energy management approach for hybrid vehicles is proposed, which optimizes the vehicle velocity profile while minimizing the fuel consumption with the help of the traffic preview information, so that a further energy saving for hybrid vehicles can be achieved. The Pontryagin’s Minimum Principle (PMP) is adopted on the proposed approach. A fuel cell hybrid vehicle (FCHV) is selected as an example, and the proposed energy management approach is applied to the FCHV in a computer simulation environment for the offline and online cases respectively. Simulation results show that the fuel economy of the FCHV is improved by the proposed energy management approach compared to a benchmark case where the driving cycle is fixed and only the hybrid power split (allocation) ratio is optimized. The proposed energy management approach is useful especially for the autonomous hybrid vehicles.

    It is difficult to control household energy consumption through regulation. From a policy standpoint, it is particularly challenging to identify the factors that influence people’s actions. Moreover, whatever these factors are, they are unlikely to uniformly span multiple cities in the Asian region. In this paper, we conduct a survey of energy-saving behavior to clarify the differences among such factors across five major Asian cities. The results from these surveys in Dalian, Chongqing, Fukuoka, Bangkok, and Ho Chi Minh indicate that global warming consciousness, environmental behavior, and social interaction significantly affect energy-saving behavior. Income and age also had weak positive effects on energy-saving behaviors. Social interaction was strongly linked to energy-saving behaviors, particularly in the rural areas of Dalian and Chongqing. This result indicates that community-based activities impact energy-saving behaviors. - Highlights: ► We conduct a survey of energy saving behavior in household in major Asian cities. ► We identify the factors that influence people's actions. ► Global warming consciousness and social interaction affect people behavior. ► This indicates community-based activities impact energy-saving behaviors in Asia.

    The instability and fragmentation of the temporary aggregations of many stakeholders in construction processes are barriers to adopting new technologies. This paper investigates the influence of different stakeholders on the adoption of mature energy-saving technologies in new residential buildings. Recent literature about the influence of different stakeholders on construction processes is reviewed focusing in their interest for energy saving technologies. To gain an insight into the specific roles played by stakeholders (general contractors, construction firms, architects, users and public governments) in different projects, a case study methodology was used. The influence on the adoption of energy-saving technologies of stakeholders was assessed through semi-structured interviews. These interviews focused on the interest and power for the adoption of several energy-saving technologies. Having recognized that the interest in adoption is often expressed late in the construction processes, the time of introduction of this interest was assessed. This paper provides an empirical insight into significant barriers for the adoption of energy saving technologies which are the low influence of highly motivated stakeholders on the decision of adoption, and the delay at which the interest in energy-saving technologies emerges. Finally, policies to overcome these barriers are suggested. - Highlights: • Why energy saving technologies are rarely adopted in buildings? • Diffusion is slowed by the late participation of stakeholders with great interest for energy technologies. • The influence of construction stakeholders for the adoption of energy saving technologies is measured in Italian case studies. • More integrated relationships among stakeholders are required to help the adoption of energy saving technologies. • Process re-organizations and policies which increase final users’ power are needed

    Introduction of EPBD in legislation of the EU member states caused that buildings must meet very stringent requirements of thermal protection and energy efficiency. On the basis of EPBD provisions, EU Member States introduce standard of NZEB (Nearly Zero-Energy Buildings). Such activities cause a need for new, innovative materials and technologies, and new approaches to design, construction and retrofitting of buildings. Indispensable is the precise coordination of the design of structure and technical installations of building, which may be provided in an integrated design process in the system BIM. Good coordination and cooperation of all contractors during the construction phase is also necessary. The article presents the problems and the new methodology for the design, construction and use of energy efficient buildings in terms of energy saving technologies, including discussion of the significant impact of the automation of technical installations on the building energy efficiency.

    Full Text Available The volt - amperes characteristic of various water solutions of ethyl alcohol and multicomponent organic substances of juices and wines were investigated. Three characteristic zones are revealed. A zone of low voltage (0-3.5V and small currents fading in time. The zone of linear dependence of a current on the application voltage (4-14V and a zone of nonlinear dependence of electrical conductivity at voltage more then 15 V for the given design of a measuring cell. The linear parts of characteristics can be used to develop the techniques for express train analysis of the volumetric contents of ethyl alcohol in a solution at low expenses of energy. It is established that the short-term influence of an electric field does not result in seen changes of initial parameters of a product.

    2016-11-01

    Full Text Available Towards sustainable Higher Education Institutions (HEIs, energy consumption behaviour is one of several issues that require an attention by facilities manager. Information from the behavioural aspect would be useful for facilities manager on managing the energy and determining potential energy saving. A lack of information negatively affects this aim. Hence, this paper proposes a methodology for assessing the energy consumption behaviour with the objective determining potential energy saving. The method used energy culture framework as basis and joined with centrographic approach and multiple-regression analysis. A self-administrated survey carried out involving 1400 respondents in selected HEIs. There are four types of energy use among students in HEIs namely, 'high', 'low', ‘medium’ and 'conserve' determined from the centrographic analysis. The energy consumption behaviour model was developed and tested against the holdout sample. Through the model's application, there is a vast potential for energy savings with over 55 kWh daily among the students.

    2013-01-01

    This paper attempts to measure consumers' perceived net benefits (or net costs) of energy-saving measures in using energy-consuming durable goods. Using the estimated net costs and the volume of CO 2 reduced by the measures, a marginal abatement cost (MAC) curve for the average household's CO 2 emissions is produced. An analysis using the curve suggests that in order to provide households with an incentive to take actions that can lead to CO 2 emission reductions in using energy-consuming durables, a high level of carbon price is needed. In addition, a regression analysis reveals that the net benefits of the measures are larger for households that put a higher priority on energy saving, for those living in detached houses, for those with a smaller number of persons living together, and for those with less income. The result of the analysis using the MAC curve may suggest that promoting energy-saving behavior will require not only a policy to provide economic incentives but also interventions to influence psychological factors of household behavior. - Highlights: • Consumers' perceived net costs of energy-saving measures in using energy-consuming durables are measured. • Using the estimated net costs, a marginal abatement cost (MAC) curve for the average household's CO 2 emissions is produced. • A high carbon price is needed in order to provide households with an incentive to take actions for energy-savings. • Households' attributes affecting their energy-saving behavior are revealed by a regression analysis

    2013-01-15

    This report describes a new analysis tool for the evaluation of realised energy savings, and effects of savings policy, in the Netherlands. It aims to meet the information needs of policymakers, both at national and EU level, using the monitoring results of the NL Agency. The system builds on the Protocol Monitoring Energy Savings to calculate realised savings. The innovation consists of the option to adjust energy models per sector, as already used for scenario analysis, to simulate past developments. The simulations can estimate total savings and assess the contribution of policy measures. The detailed simulation approach also enables the decomposition of energy trends into volume-effects due to growth, structural effects such as fuel substitution and import/exports, and various saving effects. As the modeling system is already used for the analysis of future trends, it enables a good comparison between ex-ante (expected) savings and ex-post (realised) savings. Finally, the system enables a faster delivery of calculation results than presently is the case.

    One of the most difficult problem in the use of artificial neural networks is the computational capacity. Although large search engine companies own specially developed hardware to provide the necessary computing power, for the conventional user only remains the state of the art method, which is the use of a graphic processing unit (GPU) as a computational basis. Although these processors are well suited for large matrix computations, they need massive energy. Therefore a new processor on the basis of a field programmable gate array (FPGA) has been developed and is optimized for the application of deep learning. This processor is presented in this paper. The processor can be adapted for a particular application (in this paper to an organic farming application). The power consumption is only a fraction of a GPU application and should therefore be well suited for energy-saving applications.

  19. Methods for assessing the energy-saving efficiency of industrial symbiosis in industrial parks.

    2015-01-01

    The available energy resources are being depleted worldwide. Industrial symbiosis (IS) provides a promising approach for increasing the efficiency of energy utilization, with numerous studies reporting the superiority of this technology. However, studies quantifying the energy-saving efficiency of IS remain insufficient. This paper proposes an index system for the quantitative evaluation of the energy-saving efficiency of IS. Both energy-saving and financial indexes were selected, the former include the IS energy-saving index, the contribution rate of energy saved through IS, fractional energy savings, and cut rate of energy consumption per total output value; and the latter include the IS investment payback period, IS input-output ratio, net present value (NPV), and internal rate of return (IRR) of IS. The proposed methods were applied to a case study on the XF Industrial Park (XF IP), in the city of Liaocheng in Shandong Province of China. Three energy-saving channels using IS were found in the XF IP: (a) utilizing the energy of high-temperature materials among industrial processes, (b) recovering waste heat and steam between different processes, and (c) saving energy by sharing infrastructures. The results showed that the energy efficiency index of IS was 0.326, accounting for 34.6% of the comprehensive energy-saving index in 2011, and the fractional energy-savings were 12.42%. The index of energy consumption per total industrial output value varied from 90.9 tce/MRMB to 51.6 tce/MRMB. Thus, the cut rate of energy consumption per total industrial output value was 43.42%. The average values of the IS input-output ratio was 406.2 RMB/tce, 57.2% lower than the price of standard coal. Static investment payback period in the XF IP was 8.5 months, indicating that the XF IP began to earn profit 8.5 months after the construction of all IS modes. The NVP and IRR of each IS mode in the XF IP were greater than zero, with average values equal to 1,789.96 MRMB and 140

    Highlights: • Improving DSM program impacts by targeting high energy users. • DSM energy savings potential hinges on pre-participation performance. • Targeting can benefit different utilities and energy efficiency programs. • Overall performance can be improved by up to 250% via targeting strategies. - Abstract: Electric utilities, government agencies, and private interests in the US have committed and continue to invest substantial resources – including billions of dollars of financial capital – in the pursuit of energy efficiency and conservation through demand-side management (DSM) programs. While most of these programs are deemed to be cost effective, and therefore in the public interest, opportunities exist to improve cost effectiveness by targeting programs to those customers with the greatest potential for energy savings. This article details an analysis of three DSM programs offered by three Florida municipal electric utilities to explore such opportunities. First, we estimate programs’ energy savings impacts; second, we measure and compare energy savings across subgroups of program participants as determined by their pre-intervention energy performance, and third, we explore potential changes in program impacts that might be realized by targeting specific customers for participation in the DSM programs. All three programs resulted in statistically significant average (per-participant) energy savings, yet average savings varied widely, with the customers who performed best (i.e., most efficient) before the intervention saving the least energy and those who performed worst (i.e., least efficient) before the intervention saving the most. Assessment of alternative program participation scenarios with varying levels of customer targeting suggests that program impacts could be increased by as much as 80% for a professional energy audit program, just over 100% for a high-efficiency heat pump upgrade program, and nearly 250% for an attic insulation

    Many years' efforts within the energy labelling area have shown large saving potentials in heating and use of electricity in buildings. At the same time it has been proved that these saving potentials, even when economically advantageous, only are cashed to a limited extent. The reason to this is ascribed to barriers that meet the individual building owner who wants to start saving energy. Most barriers are known and a lot of these have been sought overcome for some time. The questions are how many barriers still exist, have new barriers arisen and the character of these barriers. On this background the objective of this survey has been to concretize and study the barriers, which are blocking reasonable energy savings. Focus has especially been on barriers for realisation of heating savings, but through a general evaluation of energy savings of barriers other forms of energy saving methods have been taken into consideration. Special interest has been directed towards houses, typically one family houses, which are affected by the Energy Labelling Scheme. The concept barriers include all kinds of barriers, also barriers that not are acknowledged as barriers by the individual house owner, or that on closer inspection turn out to be something else than actual barriers. This note suggests an alternative inertia model, in order to create an idea of the inertness characteristic of the many house owners who understand the message but fail to act on it. (BA)

  2. Scenarios of energy sobriety and societal transformations. When lifestyle and society changes mean energy savings

    2013-09-01

    By using prospective energy scenarios, the objective of this study performed in the Nord-Pas-de-Calais region is to quantify energy savings induced by possible public policies or by lifestyle changes, and then to use the obtained results as tools of support to public decision, and means to make people aware of the end of an abundant and cheap oil, of the potential of solar energy, and of the benefits of energy sobriety. Four scenarios are thus defined. The first one concerns food habits, and corresponds to a more biological production, seasonal and less transformed foodstuffs, more vegetal plates, and reduced distances between producers and consumers. The second one concerns material goods: evolution towards more mutualization, re-use, and durability of products, and a reduced usage of equipment. The third one concerns buildings: the end of individual equipment and of always increasing surfaces, a modulated comfort depending on the room, and more collective organisations. The last scenario concerns displacements: less frequent displacements, shorter distances, use of soft modes, smaller vehicles, and energy saving in the use of vehicles

    Evapotranspiration (ET) is an important process of land surface water and thermal cycling, with large temporal and spatial variability. To reveal the effect of water-saving irrigation (WSI) on rice ET at different spatial scales and understand the cross spatial scale difference, rice ET under WSI condition at canopy (ETCML) and field scale (ETEC) were measured simultaneously by mini-lysimeter and eddy covariance (EC) in the rice season of 2014. To overcome the shortage of energy balance deficit by EC system, and evaluate the influence of energy balance closure degree on ETEC, ETEC was corrected as {ET}_{EC}^{*} by energy balance closure correction according to the evaporative fraction. Seasonal average daily ETEC, {ET}_{EC}^{*} and ETCML of rice under WSI practice were estimated as 3.12, 4.03 and 4.35 mm day-1, smaller than the values reported in flooded paddy fields. Daily ETEC, {ET}_{EC}^{*} and ETCML varied in a similar trends and reached the maximum in late tillering, then decreased along with the crop growth in late season. The value of ETEC was much lower than ETCML, and was frequently 1-2 h lagged behind ETCML. It indicated that the energy balance deficit resulted in underestimation of crop ET by EC system. The corrected value of {ET}_{EC}^{*} matched ETCML much better than ETEC, with a smaller RMSE (0.086 mm h-1) and higher R 2 (0.843) and IOA (0.961). The time lapse between {ET}_{EC}^{*} and ETCML was mostly shortened to less than 0.5 h. The multiple stepwise regression analysis indicated that net radiation ( R n) is the dominant factor for rice ET, and soil moisture ( θ) is another significant factor ( p important variables for understanding the spatial scale effect of rice ET in WSI fields, and for its cross scale conversion.

    An installation in a Federal building tested the effectiveness of a highly-controlled, workstation-specific lighting retrofit. The study took place in an open-office area with 86 cubicles and low levels of daylight. Each cubicle was illuminated by a direct/indirectpendant luminaire with three 32 watt lamps, two dimmable DALI ballasts, and an occupancy sensor. A centralized control system programmed all three lamps to turn on and off according to occupancy on a workstation-by-workstation basis. Field measurements taken over the course of several monthsdemonstrated 40% lighting energy savings compared to a baseline without advanced controls that conforms to GSA's current retrofit standard. A photometric analysis found that the installation provided higher desktop light levels than the baseline, while an occupant survey found that occupants in general preferred the lighting system to thebaseline.Simple payback is fairly high; projects that can achieve lower installation costs and/or higher energy savings and those in which greenhouse gas reduction and occupant satisfaction are significant priorities provide the ideal setting for workstation-specific lighting retrofits.

    Various measurements are conducted in an energy-efficient house equipped with a photovoltaic power generation system and actually lived in by people, and matching between the household load and photovoltaic power generation, and the consumption of power, are examined. As the result investigation of power consumption in the house, it is found that 13.31kWh is consumed in the daytime in winter, and 14.15kWh in summer. Thirty-two 153W modules are used, and they produce 12.74kWh in four hours on a fine summer day, which amount nearly satisfies the demand of the household. As for the records during a year beginning in May, 1996, it is found that an annual amount of 4326kWh was generated, with 68% being surplus and 32% consumed for the household. Details of the household consumption were that 49.2% was consumed for house heating and cooling and 34.1% for cooking, the two in total occupying more than 80% of the whole household consumption. Energy-saving behavior is evaluated by comparing the energy-efficient house with some ordinary residential houses in Kumamoto City, and it is found that there is a yearly difference of 104,310 yen in electricity bill or 47% in energy saving effect. 5 refs., 4 figs., 4 tabs.

    Highlights: ► Long term energy demand of Croatian households sector has been modelled. ► Developed model can describe the whole households sector. ► Main modes include heating, cooling, electrical appliances, cooking and hot water. ► Different scenarios regarding future energy demand are presented and discussed. -- Abstract: Households represent one of the most interesting sectors, when analyzing Croatia’s energy balance. It makes up one of the largest energy consumers with around 75 PJ per year, which is almost 29% of Croatia’s final energy demand. Considering this consumption, implementing various mechanisms, which would lead to improvements in energy efficiency of this sector, seems relevant. In order to plan future energy systems, important would be to know future possibilities and needs regarding energy demand of different sectors. Through this paper, long term energy demand projections of Croatian households sector will be shown. Focus of the paper will be on various mechanisms influencing future energy demand scenarios. Important would be to quantify this influence, whether positive or negative, and see which mechanisms would be the most significant. Energy demand projections in this paper are based upon bottom-up approach model which combines and processes a large number of input data. The model will be compared to Croatian National Energy Strategy and certain differences and conclusions will be presented. One of the major conclusions shown in this paper is significant possibilities for energy efficiency improvements and lower energy demand in the future, based on careful and rational energy planning. Different financial, legal and technological mechanisms can lead to significant savings in the households sector which leads to lower GHG emissions and lower Croatian dependence on foreign fossil fuels.

    2017-01-01

    Extreme learning machine (ELM), which is a simple single-hidden-layer feed-forward neural network with fast implementation, has been widely applied in many engineering fields. However, it is difficult to enhance the modeling ability of extreme learning in disposing the high-dimensional noisy data. And the predictive modeling method based on the ELM integrated fuzzy C-Means integrating analytic hierarchy process (FAHP) (FAHP-ELM) is proposed. The fuzzy C-Means algorithm is used to cluster the input attributes of the high-dimensional data. The Analytic Hierarchy Process (AHP) based on the entropy weights is proposed to filter the redundant information and extracts characteristic components. Then, the fusion data is used as the input of the ELM. Compared with the back-propagation (BP) neural network and the ELM, the proposed model has better performance in terms of the speed of convergence, generalization and modeling accuracy based on University of California Irvine (UCI) benchmark datasets. Finally, the proposed method was applied to build the energy saving and predictive model of the purified terephthalic acid (PTA) solvent system and the ethylene production system. The experimental results demonstrated the validity of the proposed method. Meanwhile, it could enhance the efficiency of energy utilization and achieve energy conservation and emission reduction. - Highlights: • The ELM integrated FAHP approach is proposed. • The FAHP-ELM prediction model is effectively verified through UCI datasets. • The energy saving and prediction model of petrochemical industries is obtained. • The method is efficient in improvement of energy efficiency and emission reduction.

    2014-01-01

    Full Text Available The article analyses directions of energy saving of industrial enterprises. Taking into account the tendency to continuous growth of cost of energy resources, introduction of measures that would allow reduction of energy consumption of enterprises is an urgent task. One of the most important obstacles in the process of introduction of energy efficient solutions are fund limits and low awareness of owners and managers of industrial enterprises. The article offers a new classification of energy saving measures: apart from traditional expense and organisation measures it introduces the low-cost measures notion. It offers to consider low-cost those measures that are realised by the enterprise by means of own funds, moreover, their repayment term is not more than one year. It offers analytical expression for identification of annual funds saving from introduction of low-cost measures. It considers the process of identification of saving of funds from introduction of some of the main low-cost measures in detail: replacement of lighting units, balancing of ventilation networks and elimination of water leakages from pipelines and water supply equipment. Based on the analysis of bibliography information the article provides a list of main measures on energy saving, which could be referred to the low-cost ones. The proposed approaches would allow paying more attention to practical aspects of realisation of the concept of energy saving in the industry.

    2011-01-01

    The objectives for energy saving in the housing sector set by recent Swedish energy and climate policies are quite demanding. This article uses nation-wide Swedish survey data from 2004 to 2007 to explore the potential for achieving those targets. Earlier findings that socio-economic characteristics such as age, housing type and income are strongly linked to higher propensities to save on heating and hot water usage are confirmed by ordered logistic regression models. However, general environmental attitudes are also found to play a crucial role. When assessing the relative importance of socio-economic factors and environmental attitudes, the effect on energy saving is generally greater for the former than the latter. In addition, important interaction effects are identified. In relative terms, the effect of environmental attitudes is clearly stronger among households in apartment blocks than among those in detached housing, and stronger among households with higher income than among those with lower income. We end by discussing the implications for the selection and targeting of policy measures to tap the energy savings potential in the population. - Highlights: → We use Swedish survey data to analyse the determinants of household energy saving. → Housing type plays a crucial role for individuals' propensity to save energy. → Environmental attitudes are clearly more important in high-income households. → Environmental attitudes are clearly more important for people in apartment blocks.

    Implementing energy conservation initiatives within public schools, including both behavioral changes as well as building retrofits, can generate cost saving and educational benefits. However, the level of energy efficiency improvements that can be achieved may depend on the socio-economic characteristics of the school or the underlying district. The purpose of this research is to identify and examine the factors that have a role in influencing the adoption of energy-saving practices and/or building retrofits within Oklahoma’s public schools. In order to investigate these factors, a survey was administered to public school administrators across the state. The results illustrate different factors that drive schools to make decisions associated with energy conservation and retrofitting efforts. A comparative analysis between different types of schools (e.g., rural vs. urban, low- vs. high-income) was also conducted to discover the combination of characteristics that are associated with energy-saving measures. The findings could help school administrators and teachers understand how they might adopt new behaviors or technologies. - Highlights: • Energy performance improvements depend on characteristics of a school district. • Districts with environmental science classes more likely to take energy measures. • Cost savings motivated energy measures in high-income/large-population districts. • A cluster analysis revealed geographic patterns of energy saving measures.

    This paper aims at providing useful insights into tourists' preferences for choosing to stay in hotels equipped with Energy Saving Installations (ESI) and Renewable Energy Sources (RES). Factors related to these decisions were studied through 2308 face to face interviews taken at the departure terminals of the two international airports of Crete, Greece. Results show that 86% of the respondents would prefer to stay in hotels equipped with ESI, and 87% in hotels with RES, rather than staying in hotels of identical quality which do not have either ESI or RES. Furthermore, the percentages of respondents who would be willing to pay fee surcharges for a hotel equipped with ESI or RES are 75 and 77%, respectively, as compared to hotels of identical quality which do not have either ESI or RES. Tourists from countries with high energy awareness, prove to be more willing to choose to stay at and pay for hotels with ESI and RES. (author)

    2014-01-01

    Full Text Available The power management of ICT systems, that is, data processing (Dp and telecommunication (Tlc systems, is becoming a relevant problem in economical terms. Dp systems totalize millions of servers and associated subsystems (processors, monitors, storage devices, etc. all over the world that need to be electrically powered. Dp systems are also used in the government of Tlc systems, which, besides requiring Dp electrical power, also require Tlc-specific power, both for mobile networks (with their cell-phone towers and associated subsystems: base stations, subscriber stations, switching nodes, etc. and for wired networks (with their routers, gateways, switches, etc.. ICT research is thus expected to investigate into methods to reduce Dp- and Tlc-specific power consumption. However, saving power may turn into waste of performance, in other words, into waste of ICT quality of service (QoS. This paper investigates the Dp and Tlc power management policies that look at compromises between power saving and QoS.

  12. A comprehensive framework to quantify energy savings potential from improved operations of commercial building stocks

    Azar, Elie; Menassa, Carol C.

    2014-01-01

    While studies highlight the significant impact of actions performed by occupants and facility managers on building energy performance, current policies ignore the importance of human actions and the potential energy savings from a more efficient operation of building systems. This is mainly attributed to the lack of methods that evaluate non-technological drivers of energy use for large stocks of commercial buildings to support policy making efforts. Therefore, this study proposes a scientific approach to quantifying the energy savings potential due to improved operations of any stock of commercial buildings. The proposed framework combines energy modeling techniques, studies on human actions in buildings, and surveying and sampling methods. The contributions of this study to energy policy are significant as they reinforce the role of human actions in energy conservation, and support efforts to integrate operation-focused solutions in energy conservation policy frameworks. The framework's capabilities are illustrated in a case study performed on the stock of office buildings in the United States (US). Results indicate a potential 21 percent reduction in the current energy use levels of these buildings through realistic changes in current building operation patterns. - Highlights: • Human actions highly influence energy performance of commercial building stocks. • It is challenging to quantify operation-related energy savings potential. • The proposed framework quantifies potential energy savings from improved operations. • The framework can be applied on any stock of commercial buildings. • Applications include support for operation-focused solutions in energy policies

    The ODYSSEE database on energy efficiency indicators (www.odyssee-indicators.org) has been set up to enable the monitoring and evaluation of realised energy efficiency improvements and related energy savings. The database covers the 27 EU countries as well as Norway and Croatia. Energy indicators that relate energy consumption to a physical output (ton of steel), a performance (person-km driven per car) or the number of energy using devices (refrigerators) can show the increase in energy efficiency realised, and the amount of energy saved. By aggregating indicators, Odyssee calculates energy efficiency indices by sector and for the whole economy (so-called ODEX), in order to evaluate overall energy efficiency progress. This work contributes to the growing need for quantitative monitoring and evaluation of the impacts of energy policies and measures, both at the EU and national level, e.g. due to the Energy Service Directive. Because of the central role of Odyssee indicators in policy evaluations it becomes more important to know how reliable the Odyssee figures are, or in other words, what is the uncertainty margin for the indicator values and the related savings. This report presents a first analysis of uncertainty margins in the indicators and savings figures. The work builds on earlier work in the preceding Odyssee project with regard to the quality of input data used in Odyssee.

    Full Text Available Energy consumption reduction under changing climate conditions is a major challenge in buildings design, where excessive energy consumption creates an economic and environmental burden. Improving thermal performance of the buildings through support applying phase change material (PCM is a promising strategy for reducing building energy consumption under future climate change. Therefore, this study aims to investigate the energy saving potentials in buildings under future climate conditions in the humid and snowy regions in the hot continental and humid subtropical climates of the east Asia (Seoul, Tokyo and Hong Kong when various PCMs with different phase change temperatures are applied to a lightweight building envelope. Methodology in this work is implemented in two phases: firstly, investigation of energy saving potentials in buildings through inclusion of three types of PCMs with different phase temperatures into the building envelop separately and use weather file in the present (2017; and, secondly, evaluation of the effect of future climate change on the performance of PCMs by analyzing energy saving potentials of PCMs with 2020, 2050 and 2080 weather data. The results show that the inclusion of PCM into the building envelope is a promising strategy to increase the energy performance in buildings during both heating and cooling seasons in Seoul, Tokyo and Hong Kong under future climate conditions. The energy savings achieved by using PCMs in those regions are electricity savings of 4.48–8.21%, 3.81–9.69%, and 1.94–5.15%, and gas savings of 1.65–16.59%, 7.60–61.76%, and 62.07–93.33% in Seoul, Tokyo and Hong Kong, respectively, for the years 2017, 2020, 2050 and 2080. In addition, BioPCM and RUBITHERMPCM are the most efficient for improving thermal performance and saving energy in buildings in the tested regions and years.

  20. Calibrated energy simulations of potential energy savings in actual retail buildings

    Science.gov (United States)

    Alhafi, Zuhaira

    Retail stores are commercial buildings with high energy consumption due to their typically large volumes and long hours of operation. This dissertation assesses heating, ventilating and air conditioning saving strategies based on energy simulations with input parameters from actual retail buildings. The dissertation hypothesis is that "Retail store buildings will save a significant amount of energy by (1) modifying ventilation rates, and/or (2) resetting set point temperatures. These strategies have shown to be beneficial in previous studies. As presented in the literature review, potential energy savings ranged from 0.5% to 30% without compromising indoor thermal comfort and indoor air quality. The retail store buildings can be ventilated at rates significantly lower than rates called for in the ASHRAE Standard 62.1-2010 while maintaining acceptable indoor air quality. Therefore, two dissertation objectives are addressed: (1) Investigate opportunities to reduce ventilation rates that do not compromise indoor air quality in retail stores located in Central Pennsylvania, (2) Investigate opportunities to increase (in summer) and decrease (in winter) set point temperatures that do not compromise thermal comfort. This study conducted experimental measurements of ventilation rates required to maintain acceptable air quality and indoor environmental conditions requirements for two retail stores using ASHRAE Standard 62.1_2012. More specifically, among other parameters, occupancy density, indoor and outdoor pollutant concentrations, and indoor temperatures were measured continuously for one week interval. One of these retail stores were tested four times for a yearlong time period. Pollutants monitored were formaldehyde, carbon dioxide, particle size distributions and concentrations, as well as total volatile organic compounds. As a part of the base protocol, the number of occupants in each store was hourly counted during the test, and the results reveal that the occupant

    Highlights: • Establish the synergy relationship of material and energy in key RKEF processes. • Develop an analysis model to study energy saving with internal cycling of energy. • Analyze material and energy flow parameters and assess its associated synergy effect. • A methodology to evaluate the synergy and design indices of RKEF processes. - Abstract: An energy saving strategy with two energy saving measures has been proposed for reducing energy loss in the rotary kiln-electric furnace (RKEF) for the smelting of ferronickel alloy. One of the measures is to recover the waste heat of exhaust gas from the rotary kiln for preheating and dehydrating the wet laterite ores in the rotary dryer. Another measure is to recycle the furnace gas from the electric furnace into the rotary kiln as fuel. Based on the mass conservation and energy conservation laws, an analysis model of material and energy flows has been developed to understand the potential energy saving with the internal cycling of material and energy in the RKEF process. The analysis model not only considers the energy efficiency but also assess the synergy degree of system. Furthermore, the model also predicts the ratio of raw materials and the energy flow distribution to investigate residual heat and energy and analyze the effects of nickel content on energy flow. Finally, the evaluation methodology of synergy and the technic indices are also presented. Through the investigation of the synergy effect, the performance of the RKEF process can be evaluated and quantified for performance optimization in future.

    Full Text Available The performance parameters, energetic characteristics and cost factors of direct drilling were evaluated by longterm trials carried out in Osztopán and Gödöllő regions. The effect of direct drilling, disking, ploughing, and soil loosening combined with disking and ploughing on the soil conditions, yields and cost factors was evaluated and based on the examination results. The economic comparisons were done by gross margin analyses of various technologies. Reducing the number of field applications is limited by the risk of soil compactions and weed infestations. From an economic part of view cost saving aspects of the various cultivation methods mentioned above cannot be justified in comparison with the ploughing methods. The lowest gross margin value was 61.79 EUR t-1, direct drilling and the highest was 67.34 EUR t-1, with ploughing but it was due to the great difference between the yield as well (6.89 and 4.03 t.ha-1. The results we achieved during our research are valid only in the given conditions, they could be recalculated and complemented under other soil and agro-ecological conditions. Our purpose was to emphasise the necessity of economical calculations before making decisions on changing technology. Our suggestion is: combined application of the traditional and energy saving methods, regarding the local conditions as well.

    Highlights: • We compare public participation in three early cases of residential retrofitting in Beijing. • Residents’ involvement in pre-retrofit activities as well as in the choice and use of technologies varied. • More involvement of residents during retrofitting improves energy saving performance. • Taking into account motives and energy use practices of residents improves energy saving through retrofitting. - Abstract: Retrofitting existing residential buildings has been claimed as one crucial way to reduce energy consumption and greenhouse gas emissions within the Chinese residential sector. In China’s government-dominated retrofitting projects, the participation of residents is often neglected. The objective of this paper is to assess the influence level of public participation (before, during and after retrofit) on energy saving by comparing three Beijing neighborhoods with different retrofitting models: a central government-led model, a local government-led model, and an old neighborhood retrofit model. In the three cases data were collected through interviews with neighborhood workers and residents. The results show that residents’ involvement in pre-retrofit activities, in technology selection and in the use of technology differs greatly among the three cases. This study concludes that in order to improve the effectiveness of energy saving interventions, the motives, intentions and living habits of residents need to be given more consideration when designing and implementing retrofitting. By highlighting the importance of public participation this paper contributes to energy saving policy development in China

    Under its National Deep Energy Retrofit (NDER) program, the U.S. General Services Administration (GSA) awarded 10 ESPC projects with the objectives of using innovative technologies and renewable energy technologies, and moving buildings toward net zero energy consumption. This report analyzes data on energy savings from the 10 NDER projects, and compares them with the savings of a sample of other recently awarded Federal ESPC projects. It is shown that by emphasizing the need for deeper energy savings, and by the establishment of a central Project Management Office (PMO) to provide authoritative contracting, technical and pricing assistance, the NDER projects achieved an average level of savings more than twice that of the other Federal ESPC projects. The level of savings achieved in each project seems to be dependent more on the availability of ECMs at the site than on energy price, energy cost per square foot, pre-retrofit EUI or the length of the contract term. This suggests that GSA can achieve similar results in a wide variety of building

  8. A New Method to Energy Saving in a Micro Grid

    Full Text Available Optimization of energy production systems is a relevant issue that must be considered in order to follow the fossil fuels consumption reduction policies and CO2 emission regulation. Increasing electricity production from renewable resources (e.g., photovoltaic systems and wind farms is desirable but its unpredictability is a cause of problems for the main grid stability. A system with multiple energy sources represents an efficient solution, by realizing an interface among renewable energy sources, energy storage systems, and conventional power generators. Direct consequences of multi-energy systems are a wider energy flexibility and benefits for the electric grid, the purpose of this paper is to propose the best technology combination for electricity generation from a mix of renewable energy resources to satisfy the electrical needs. The paper identifies the optimal off-grid option and compares this with conventional grid extension, through the use of HOMER software. The solution obtained shows that a hybrid combination of renewable energy generators at an off-grid location can be a cost-effective alternative to grid extension and it is sustainable, techno-economically viable, and environmentally sound. The results show how this innovative energetic approach can provide a cost reduction in power supply and energy fees of 40% and 25%, respectively, and CO2 emission decrease attained around 18%. Furthermore, the multi-energy system taken as the case study has been optimized through the utilization of three different type of energy storage (Pb-Ac batteries, flywheels, and micro—Compressed Air Energy Storage (C.A.E.S..

    The majority of the traffic over the Internet is TCP based, which is very sensitive to packet loss and delay. Existing research efforts in TDM-Passive Optical Networks (TDM-PONs) mostly evaluate energy saving and traffic delay performances under different energy saving solutions. However, to the best of our knowledge, how energy saving mechanisms could affect TCP traffic performance in TDM-PONs has hardly been studied. In this paper, by means of our state-of-art OPNET Modular based TDM-PON simulator, we evaluate TCP traffic delay, throughput, and Optical Network Unit (ONU) energy consumption performances in a TDM-PON where energy saving mechanisms are employed in ONUs. Here, we study the performances under commonly used energy saving mechanisms defined in standards for TDM-PONs: cyclic sleep and doze mode. In cyclic sleep mode, we evaluate the performances under two well-known sleep interval length deciding algorithms (i.e. fixed sleep interval (FSI) and exponential sleep interval deciding (ESID)) that an OLT uses to decide sleep interval lengths for an ONU. Findings in this paper put forward the strong relationship among TCP traffic delay, throughput and ONU energy consumption under different sleep interval lengths. Moreover, we reveal that under high TCP traffic, both FSI and ESID will end up showing similar delay, energy and throughput performance. Our findings also show that doze mode can offer better TCP throughput and delay performance at the price of consuming more energy than cyclic sleep mode. In addition, our results provide a glimpse on understanding at what point doze mode becomes futile in improving energy saving of an ONU under TCP traffic. Furthermore, in this paper, we highlight important research issues that should be studied in future research to maximize energy saving in TDM-PONs while meeting traffic Quality of Service requirements.

    Highlights: • Some households’ adaptations to electricity shortage can be new efficient habits. • The electricity shortage in Japan was used as a natural experiment. • Some behaviors contributed to 2–4% electricity savings and persisted for two years. • Behaviors requiring frequency and discomfort cannot be effective or persistent. • Lowering the electricity-usage level of appliances might be a promising behavior. - Abstract: This paper focuses on households’ development of new energy-efficient habits as demonstrated in the context of a major electricity shortfall event. Energy conservation policies should encourage households to take measures that are actually effective in reducing energy consumption and that can be sustained over long periods of time. Few studies, however, have empirically examined what types of energy-saving measures are actually effective and persistent. The electricity shortages following the 2011 Great East Japan earthquake, tsunami, and nuclear disaster provided an opportunity to examine this question. A web survey of households in Japan was implemented to obtain data on metered electricity use in the summers of 2010–2013, household behaviors for electricity savings, and household socioeconomic attributes. Regression analysis was conducted to explain the effectiveness and persistence of energy saving behaviors. Results indicate that most households took several electricity-saving measures after the disaster to adapt to the electricity shortage. Certain types of measures led to 2–4% savings in electricity consumption (per measure) and persisted for two years. The effective and persistent electricity-saving measures tended to be those that did not require either frequent efforts or considerable discomfort. Findings suggest that electricity-saving behaviors requiring infrequent effort and little discomfort can become engrained as new habits or lifestyles. In particular, one promising measure may be to lower the electricity

    2016-01-01

    This study examined the influence of additional and replacement purchases of energy-efficient air-conditioners on power savings. We used a questionnaire survey and measured electricity use data from 339 Japanese households, collected from two city areas with different level of government-requested electricity-saving rates, namely, Osaka (10%) and Matsuyama (5%). The main findings of our study are as follows: (1) Households that purchased energy-efficient air-conditioners saved more electricity than those that did not. (2) “Additional-purchase households” showed significant energy savings, whereas “replacement households” did not. The rebound effect may negate the energy-saving effects of a new air-conditioner. (3) Altruistic attitude is associated with more active participation in power saving. (4) Households in Osaka saved more electricity than those in Matsuyama, probably because the government call to save electricity was more forceful. - Highlights: •Energy efficient air conditioner purchases affect household power savings. •Additional air conditioner purchase led to significant energy savings. •Replacement units did not produce more savings than non-purchase. • “Electricity conservation directives” amount had a significant power-saving effect. •Altruistic households were more likely to cooperate with power-saving requests.

    In October 2011, ARBI organized and conducted an Experts' Meeting on the topic of performance guarantees and financing vehicles for Energy Efficiency Upgrades. The meeting brought together technical, policy, and financial experts, including researchers, experienced installation contractors, and innovative energy business leaders, in order to discuss the opportunities and challenges for the energy efficiency upgrade industry to increase market uptake of Home Energy Upgrades (HEUs) through innovative offerings, such as performance guarantees. The meeting had several primary goals. First, it sought to understand how other industries have developed successful models for financing renewable energy installations while providing performance guarantees. This has been most recently demonstrated by the solar leasing industry. Second, the meeting explored the applicability of such business models to the energy efficiency upgrade industry. Third, the meeting sought to identify technical impediments to performance guarantees for energy efficiency retrofits. Fourth, the meeting sought to provide a common framework for these goals within the context of current financing mechanisms for energy efficiency upgrades.

  2. A simple tool for estimating city-wide annual electrical energy savings from cooler surfaces

    Energy Technology Data Exchange (ETDEWEB)

    Pomerantz, Melvin; Rosado, Pablo J.; Levinson, Ronnen

    2015-12-01

    We present a simple method to estimate the maximum possible electrical energy saving that might be achieved by increasing the albedo of surfaces in a large city. We restrict this to the “indirect effect”, the cooling of outside air that lessens the demand for air conditioning (AC). Given the power demand of the electric utilities and data about the city, we can use a single linear equation to estimate the maximum savings. For example, the result for an albedo change of 0.2 of pavements in a typical warm city in California, such as Sacramento, is that the saving is less than about 2 kWh per m2 per year. This may help decision makers choose which heat island mitigation techniques are economical from an energy-saving perspective.

    This study investigates intervention strategy in stimulating energy-saving behavior to achieve energy neutral urban development. A tree structure overview of potential interventions classified into three categories is revealed. An integrated behaviour model is developed reflecting the relations between behaviour and influence factors. A latent class model is used to identify segments of local residents who differ regarding their preferences for interventions. Data are collected from a sample of residents in the Eindhoven region of the Netherlands in 2010. The results indicate that social-demographic characteristics, knowledge, motivation and context factors play important roles in energy-saving behaviour. Specifically, four segments of residents in the study area were identified that clearly differed in their preferences of interventions: cost driven residents, conscious residents, ease driven residents and environment minded residents. These findings emphasize that the intervention strategy should be focused on specific target groups to have the right mixture of interventions to achieve effective results on stimulating them to save energy. - Highlights: ► A latent class model to identify segments with preferred energy-saving interventions. ► An integrated energy-saving behavior model of casual relations. ► A tree structure overview of potential interventions

    Highlights: ► Super-capacitors are used to store regenerative braking energy in a metro network. ► A novel approach is proposed to model easily and accurately the metro network. ► An efficient approach is proposed to calculate the required super-capacitors. ► Maximum energy saving is around 44% at off-peak period and 42% at peak period. ► Benefit/cost analyses are performed for the suggested ESS. - Abstract: In this paper, the stationary super-capacitors are used to store a metro network regenerative braking energy. In order to estimate the required energy storage systems (ESSs), line 3 of Tehran metro network is modeled through a novel approach, in peak and off-peak conditions based on the real data obtained from Tehran metro office. A useful method is proposed to predict the maximum instantaneous regenerative energy which is delivered to each station before applying ESS and based on that the ESS configuration for each station is determined. Finally, the effectiveness of the proposed ESS is confirmed by economic evaluations and benefit/cost analyses on line 3 of Tehran metro network.

  5. Hydrodynamics and energy-saving swimming techniques of Pacific bluefin tuna.

    Science.gov (United States)

    Takagi, Tsutomu; Tamura, Yumiko; Weihs, Daniel

    2013-11-07

    Weihs theoretically revealed that during the movement of fish with negative buoyancy, more kinetic energy is saved in the glide and upward (GAU) swimming mode than in the continuous horizontal swimming mode. Because kinetic energy saving depends on dynamic parameters such as the drag and lift of the body, the effects of variations in these parameters on energy saving for different species remain unknown. Here, the kinetic energy saving of Pacific bluefin tuna (PBT), Thunnus orientalis, exhibiting the GAU swimming mode was investigated. The dynamic properties of PBT were estimated by carrying out CFD analysis. The CFD model was produced by using a three-dimensional laser surface profiler, and the model was controlled such that it exhibited swimming motion similar to that of a live PBT swimming in a flume tank. The drag generated by tail beating, which significantly affects the kinetic energy during motion, was twice that generated in the glide mode. The faster the upward swimming speed, the lesser is the kinetic energy saving; therefore, when the upward swimming speed is more than twice the glide speed, there is no gain in the GAU mode. However, when SMR (Standard Metabolic Rate) is considered, if the energy based on SMR is assumed to be 30% of the total energy spent during motion, the most efficient upward swimming speed is 1.4 times the glide speed. The GAU swimming mode of PBT leads to energy saving during motion, and the upward swimming speed and the lift force produced by the pectoral fins for the most efficient drive are unique for different species of different sizes. © 2013 Elsevier Ltd.

    Relocatable classrooms (RCs) are commonly used by school districts with changing demographics and enrollment sizes. We designed and constructed four energy-efficient RCs for this study to demonstrate technologies with the potential to simultaneously improve energy efficiency and indoor environmental quality (IEQ). Two were installed at each of two school districts, and energy use and IEQ parameters were monitored during occupancy. Two RCs (one per school) were finished with materials selected for reduced emissions of toxic and odorous volatile organic compounds (VOCs). Each had two HVAC systems, operated on alternate weeks, consisting of a standard heat-pump system and an indirect-direct evaporative cooling (IDEC) system with gas-fired hydronic heating. The IDEC system provides continuous outside air ventilation at {sup 3}15 CFM (7.5 L s-1) person-1, efficient particle filtration while using significantly less energy for cooling. School year long measurements included: carbon dioxide (CO2), particles, VOCs, temperature, humidity, thermal comfort, noise, meteorology, and energy use. IEQ monitoring results indicate that important ventilation-relevant indoor CO2 and health-relevant VOC concentration reductions were achieved while average cooling and heating energy costs were simultaneously reduced by 50 percent and 30 percent, respectively.

    After more than 40 years of effort, energy efficiency program administrators and associated contractors still find it challenging to penetrate the home retrofit market, especially at levels commensurate with state and federal goals for energy savings and emissions reductions. Residential retrofit programs further have not coalesced around a reliably successful model. They still vary in design, implementation and performance, and they remain among the more difficult and costly options for acquiring savings in the residential sector. If programs are to contribute fully to meeting resource and policy objectives, administrators need to understand what program elements are key to acquiring residential savings as cost effectively as possible. To that end, the U.S. Department of Energy (DOE) sponsored a comprehensive review and analysis of home energy upgrade programs with proven track records, focusing on those with robustly verified savings and constituting good examples for replication. The study team reviewed evaluations for the period 2010 to 2014 for 134 programs that are funded by customers of investor-owned utilities. All are programs that promote multi-measure retrofits or major system upgrades. We paid particular attention to useful design and implementation features, costs, and savings for nearly 30 programs with rigorous evaluations of performance. This meta-analysis describes program models and implementation strategies for (1) direct install retrofits; (2) heating, ventilating and air-conditioning (HVAC) replacement and early retirement; and (3) comprehensive, whole-home retrofits. We analyze costs and impacts of these program models, in terms of both energy savings and emissions avoided. These program models can be useful guides as states consider expanding their strategies for acquiring energy savings as a resource and for emissions reductions. We also discuss the challenges of using evaluations to create program models that can be confidently applied in

    Since one of the restrictive problems when investing in energy saving is the uncertainty of obtaining the planed savings, a technique in the risk handling for energy efficiency projects, called Insurance for the Energy Saving (IES) is presented. IES economically stimulates those who implement projects for energy saving so they go beyond the normal measures and really obtain significant saving levels, thus contributing to the fulfillment of national objectives in energy saving. In order to reduce the risk of low performance in energy caused by saving projects there exist the international performance measurement and the protocol of investment (IMPVP) as well as diagnoses and starting processes, whereas in order to transfer the financial risk that a saving project represents, mechanisms such as FDIC insurance, conversion of the debt in values, Saving's Guarantees, Performance Bonuses or Guarantee Bonuses and Insurances for Energy Saving can be of great help.

    With the development of advanced continuous-casting technology, saving energy and reducing greenhouse gas emissions are crucial for its future development. Controlling the initial solidification of molten steel in the mold to improve the quality of casting products would tend to minimize extra postcast treatment like scarfing, etc., which leads to a large amount of energy savings in the continuous-casting process through the minimization of the extra labor and energy consumption. In this article, factors such as mold flux, mold oscillation, cooling potential conditions, and fluid flow in the vicinity of meniscus that correlate with the molten steel initial solidification are discussed with the aim to provide strategy and guidelines for the optimization of molten steel solidification and energy savings in continuous casting.

    The current focus on building energy retrofit provides an opportunity to simultaneously improve indoor environmental quality (IEQ). Toward this end, we developed a protocol for selecting packages of retrofits that both save energy and improve IEQ in apartments. The protocol specifies the methodology for selecting retrofits from a candidate list while addressing expected energy savings, IEQ impacts, and costs in an integrated manner. Interviews, inspections and measurements are specified to collect the needed input information. The protocol was applied to 17 apartments in three buildings in two different climates within California. Diagnostic measurements and surveys conducted before and after retrofit implementation indicate enhanced apartment performance.

    In the general frame of energy saving, environment protection and the concept of circular economy, the fundamental research on the sintering technology with super deep bed, achieving energy saving and emission reduction, was carried out. At first, the characteristics of the process and exhaust emission in the sintering with super deep bed was mastered through the study of the influence of different bed depths on the sintering process. Then, considering the bed permeability and the fuel combustion, their influence on the sinter yield and quality, their potential for energy saving and emission reduction was studied. The results show that the improvement of the bed permeability and of the fuel combustibility respectively and simultaneously, leads to an improvement of the sintering technical indices, to energy saving and emission reduction in the condition of super deep bed. At 1000 mm bed depth, and taking the appropriate countermeasure, it is possible to decrease the solid fuel consumption and the emission of CO 2 , SO 2 , NO x by 10.08%, 11.20%, 22.62% and 25.86% respectively; and at 700 mm bed depth, it is possible to reduce the solid fuel consumption and the emission of CO 2 , SO 2 , NO x by 20.71%, 22.01%, 58.86% and 13.13% respectively. This research provides the theoretical and technical basis for the new technology of sintering with super deep bed, achieving energy saving and reduction of emission. (authors)

  7. Assessment of energy savings and of side effects associated with consumption cutoffs. Complete report + abridged version

    International Nuclear Information System (INIS)

    2016-03-01

    As France has been the first European country to implement a legal and regulatory framework which acknowledges the role of cut-off operators, and promotes their direct participation to markets, this report aims at preparing an evolution of this framework, notably by focusing on the notion of energy saving. It highlights the importance of definitions regarding levels of consumption deferment and of energy saving associated with consumption cutoffs. The report first analyses the context: assessment of energy savings associated with consumption cutoffs, discussion of the existence or absence of a typical profile of consumption deferment, and definition of a consumption deferment rate, importance of these works for cut-off integration into the electric power system. It proposes a presentation of the present status of knowledge on energy savings and side effects, defines the energy saving rate, and discusses the sensitivity of this rate to calculation parameters. The next part presents the method adopted to analyse results obtained during experiments. The obtained results are then discussed by distinguishing those obtained in the industrial sector, in the tertiary sector, and in the residential sector. Economic studies are then reported regarding the impact of a wrong choice for the deferment rate on market mechanism rules, and the impact of an explicit taking of the deferment into account. Appendices contain detailed presentations of some specific aspects of these assessments and studies. An abridged version of the report is then provided

    Heat pump water heaters (HPWHs) have recently re-emerged in the U.S. residential water heating market and have the potential to provide homeowners with significant energy savings. However, there are questions as to the actual performance and energy savings potential of these units, in particular in regards to the heat pump's performance in unconditioned space and the impact of the heat pump on space heating and cooling loads when it is located in conditioned space. To help answer these questions, NREL performed simulations of a HPWH in both conditioned and unconditioned space at over 900 locations across the continental United States and Hawaii. Simulations included a Building America benchmark home so that any interaction between the HPWH and the home's HVAC equipment could be captured. Comparisons were performed to typical gas and electric water heaters to determine the energy savings potential and cost effectiveness of a HPWH relative to these technologies. HPWHs were found to have a significant source energy savings potential when replacing typical electric water heaters, but only saved source energy relative to gas water heater in the most favorable installation locations in the southern United States. When replacing an electric water heater, the HPWH is likely to break even in California, the southern United States, and parts of the northeast in most situations. However, the HPWH will only break even when replacing a gas water heater in a few southern states.

  1. Simulation of Energy Savings in Automotive Coatings Processes

    Science.gov (United States)

    Gerini Romagnoli, Marco

    Recently, the automakers have become more and more aware of the environmental and economic impact of their manufacturing processes. The paint shop is the largest energy user in a vehicle manufacturing plant, and one way to reduce costs and energy usage is the optimization of this area. This project aims at providing a tool to model and simulate a paint shop, in order to run and analyze some scenarios and case studies, helping to take strategic decisions. Analytical computations and real data were merged to build a tool that can be used by FCA for their Sterling Heights plant. Convection and conduction heat losses were modeled for the dip processes and the ovens. Thermal balances were used to compute the consumptions of booths, decks and ovens, while pump and fan energy consumptions were modeled for each sub-process. The user acts on a calendar, scheduling a year of production, and the model predicts the energy consumption of the paint shop. Five scenarios were run to test different conditions and the influence of scheduling on the energy consumption. Two different sets of production schedules have been evaluated, the first one fulfilling the production requirement in one shift of 10 hours, at high rate, the second one using two 7-hour-long shifts at medium production rate. It was found that the unit cost was minimized in the warmest months of spring and fall, and system shutdown was a crucial factor to reduce energy consumption. A fifth hypothetical scenario was run, with a 4 month continuous production and an 8 month total shutdown, which reduced the energy consumption to a half of the best realistic scenario. When the plant was run in a two-shifts configuration, the cost to coat a vehicle was found to be 29 with weekend shutdown, and 39 without. In the one-shift configuration, the cost was slightly higher, but the difference was less than 5%. While the fifth scenario showed a consistent reduction of the unit cost, inventory and logistic expenses deriving from the

    Surprising potential exists for new and enhanced electric technologies to reduce energy use and CO 2 emission. Widespread deployment of these technologies could reduce energy use by up to 7 quads in 2010 and a corresponding reduction in carbon dioxide emission of up to 440 million tons. Electricity's unique high form value allows for efficiency at the point of end-use that is multiples of the efficiency possible in gas- or oil-fueled systems. The efficiency advantage at the point of end use more than offset the disadvantage of the high losses in the production of electricity. Hence, widespread deployment of many electric end uses will reduce the nation's total energy requirements. Major technologies which hold the greatest potential include electric process heating, industrial electrotechnologies, electric vehicles, information technologies that substitute electronic communication for transportation of people, and electric heat pumps for space heating, cooling and water heating. Wider use of these beneficial technologies in combination with the efficient use of electricity can reduce the nation's primary energy use and Co 2 emissions from electric generation by more than a quarter. 35 refs., 50 figs., 69 tabs

    An adaptation process in the transportation network of Physarum plasmodium was investigated by measuring oxygen consumption during network formation. Simultaneously, the fractal dimension as a measure of network structure was estimated. Oxygen consumption decreased during the development of the network, whereas the network structure changed from a thin mesh-type to a thick dendritic type. Our data suggested that the morphology of the plasmodial network governed energy consumption; a low dimensional network in the sense of the fractal dimension reduced energy consumption. These data were supported by experimental results excluding biological reasons, such as differences in starvation/nutrient-fullness states, and aspects of mitochondrial distribution. Model analysis using the Physarum algorithm with volume conservation constraints confirmed the above findings. (paper)

    Tulip bulbs are stored in ventilated containers to avoid high ethylene concentration between the bulbs. A commercial computational fluid dynamics (CFD) code was used in this study to examine the distribution of air flow between the containers and the potential energy saving by applying simple solutions concerning the design of the air inlet area and the adjustment of the ventilation rate. The variation in container ventilation was calculated to be between 60 and 180 per cent, with 100 per cent being the average flow through the containers. Various improvement measures were examined. The study showed that 7 per cent energy can be saved by smoothing the sharp corners of the entrance channels of the ventilation wall. The most effective and simple improvement was to cover the open top containers. In this case, the variation was between 80 and 120 per cent. The energy saving was about 38 per cent by adjusting the overall ventilation to the container with the minimal acceptable air flow.

    The furnace waste heat of a company’s existing 4 × 100t ultra-high-power electric arc furnaces is not used and discharged directly of the situation has been unable to meet the national energy-saving emission reduction requirements, and also affected their own competitiveness and sustainable development. In order to make full use of the waste heat of the electric arc furnace, this paper presents an the energy-saving transformation program of using the new heat pipe boiler on the existing ultra-high-power electric arc furnaces for recovering the waste heat of flue gas. The results show that after the implementation of the project can save energy equivalent to 42,349 tons of standard coal. The flue gas waste heat is fully utilized and dust emission concentration is accorded with the standard of Chinese invironmental protection, which have achieved good results.

    Commercial buildings in the United States use about 18 Quadrillion British thermal units (Quads) of primary energy annually . Studies have shown that as much as 30% of building energy consumption can be avoided by using more accurate sensing, using existing controls better, and deploying advanced controls; hence, the motivation for the work described in this report. Studies also have shown that 10% to 20% of the commercial building peak load can be temporarily managed/curtailed to provide grid services. Although many studies have indicated significant potential for reducing the energy consumption in commercial buildings, very few have documented the actual savings. The studies that did so only provided savings at the whole building level, which makes it difficult to assess the savings potential of each individual measure deployed.

  16. Modeling Interprovincial Cooperative Energy Saving in China: An Electricity Utilization Perspective

    Full Text Available As the world faces great challenges from climate change and environmental pollution, China urgently requires energy saving, emission reduction, and carbon reduction programmes. However, the non-cooperative energy saving model (NCESM, the simple regulation mode that is China’s main model for energy saving, is not beneficial for optimization of energy and resource distribution, and cannot effectively motivate energy saving at the provincial level. Therefore, we propose an interprovincial cooperative energy saving model (CESM from the perspective of electricity utilization, with the object of maximizing the benefits from electricity utilization of the cooperation union based on achieving the energy saving goals of the union as a whole. The CESM consists of two parts: (1 an optimization model that calculates the optimal quantities of electricity consumption for each participating province to meet the joint energy saving goal; and (2 a model that distributes the economic benefits of the cooperation among the provinces in the cooperation based on the Shapley value method. We applied the CESM to the case of an interprovincial union of Shanghai, Sichuan, Shanxi, and Gansu in China. The results, based on the data from 2001–2014, show that cooperation can significantly increase the benefits of electricity utilization for each province in the union. The total benefits of the union from utilization of electricity increased 38.38%, or 353.98 billion CNY, while the benefits to Shanghai, Sichuan, Shanxi, and Gansu were 200.28, 58.37, 57.11, and 38.22 billion CNY respectively greater under the CESM than the NCESM. The implementation of the CESM provides the provincial governments not only a flexible and incentive way to achieve short-term goals, but also a feasible and effective path to realize long-term energy saving strategies. To test the impact of different parameter values on the results of the CESM, a sensitivity analysis was conducted. Some policy

    This project was a subtask of Energy Saving Melting and Revert Reduction Technology (Energy SMARRT) Program. Through this project, technologies, such as computer modeling, pattern quality control, casting quality control and marketing tools, were developed to advance the Lost Foam Casting process application and provide greater energy savings. These technologies have improved (1) production efficiency, (2) mechanical properties, and (3) marketability of lost foam castings. All three reduce energy consumption in the metals casting industry. This report summarizes the work done on all tasks in the period of January 1, 2004 through June 30, 2011. Current (2011) annual energy saving estimates based on commercial introduction in 2011 and a market penetration of 97% by 2020 is 5.02 trillion BTU's/year and 6.46 trillion BTU's/year with 100% market penetration by 2023. Along with these energy savings, reduction of scrap and improvement in casting yield will result in a reduction of the environmental emissions associated with the melting and pouring of the metal which will be saved as a result of this technology. The average annual estimate of CO2 reduction per year through 2020 is 0.03 Million Metric Tons of Carbon Equivalent (MM TCE).

    The cost of energy as part of the total production costs in the cement industry is significant, warranting attention for energy efficiency to improve the bottom line. Historically, energy intensity has declined, although more recently energy intensity seems to have stabilized with the gains. Coal and coke are currently the primary fuels for the sector, supplanting the dominance of natural gas in the 1970s. Most recently, there is a slight increase in the use of waste fuels, including tires. Between 1970 and 1999, primary physical energy intensity for cement production dropped 1 percent/year from 7.3 MBtu/short ton to 5.3 MBtu/short ton. Carbon dioxide intensity due to fuel consumption and raw material calcination dropped 16 percent, from 609 lb. C/ton of cement (0.31 tC/tonne) to 510 lb. C/ton cement (0.26 tC/tonne). Despite the historic progress, there is ample room for energy efficiency improvement. The relatively high share of wet-process plants (25 percent of clinker production in 1999 in the U.S.) suggests the existence of a considerable potential, when compared to other industrialized countries. We examined over 40 energy efficient technologies and measures and estimated energy savings, carbon dioxide savings, investment costs, and operation and maintenance costs for each of the measures. The report describes the measures and experiences of cement plants around the wold with these practices and technologies. Substantial potential for energy efficiency improvement exists in the cement industry and in individual plants. A portion of this potential will be achieved as part of (natural) modernization and expansion of existing facilities, as well as construction of new plants in particular regions. Still, a relatively large potential for improved energy management practices exists.

    California's goal to reduce greenhouse gas (GHG) emissions to a level that is 80 % below 1990 levels by the year 2050 will require adoption of low-carbon energy sources across all economic sectors. In addition to reducing GHG emissions, shifting to fuels with lower carbon intensity will change concentrations of short-lived conventional air pollutants, including airborne particles with a diameter of less than 2.5 µm (PM2.5) and ozone (O3). Here we evaluate how business-as-usual (BAU) air pollution and public health in California will be transformed in the year 2050 through the adoption of low-carbon technologies, expanded electrification, and modified activity patterns within a low-carbon energy scenario (GHG-Step). Both the BAU and GHG-Step statewide emission scenarios were constructed using the energy-economic optimization model, CA-TIMES, that calculates the multi-sector energy portfolio that meets projected energy supply and demand at the lowest cost, while also satisfying scenario-specific GHG emissions constraints. Corresponding criteria pollutant emissions for each scenario were then spatially allocated at 4 km resolution to support air quality analysis in different regions of the state. Meteorological inputs for the year 2054 were generated under a Representative Concentration Pathway (RCP) 8.5 future climate. Annual-average PM2.5 and O3 concentrations were predicted using the modified emissions and meteorology inputs with a regional chemical transport model. In the final phase of the analysis, mortality (total deaths) and mortality rate (deaths per 100 000) were calculated using established exposure-response relationships from air pollution epidemiology combined with simulated annual-average PM2.5 and O3 exposure. Net emissions reductions across all sectors are -36 % for PM0.1 mass, -3.6 % for PM2.5 mass, -10.6 % for PM2.5 elemental carbon, -13.3 % for PM2.5 organic carbon, -13.7 % for NOx, and -27.5 % for NH3. Predicted deaths associated with air
