    Cooperation between public and private sector has achieved a remarkable widespread, in the Italian context, over the last two decades. Nevertheless, the increasing difficulty in accessing the capital market and the rising cost of funding sources, both noticeable over the past few years, led to a slowdown of Public–Private Partnership (PPP) initiatives. Meanwhile, the community is expressing new needs to be satisfied, such as the conversion of brownfields, the recovery of housing stock dating back to former times, as well as the refurbishment of public offices or schools. Emerging priorities include the supply of affordable dwellings for low to medium income households. This essay aims to examine a case study in which PPP and buildings energy efficiency have been successfully combined, in order to jointly contribute to the achievement of a social housing settlement. Thanks to energy efficiency measures—concerning building envelope insulation, heating system and other installations—the agreed rent results far higher than social rent of protected tenancies, and furthermore above the range of fair rents characterising other regulated tenancies, but mildly lower than market rents. All this allows to achieve an equity yield rate satisfying from the perspective of a venture philanthropy investment. -- Highlights: •Provision of affordable dwellings is an emerging priority within Italian context. •Lack of public funds leads to promote Public–Private Partnership schemes. •Without public grants the adoption of a venture philanthropy approach is needed. •The examined case study allows to explain the role of buildings energy efficiency. •Buildings energy efficiency may boost feasibility of social housing transactions

    The UK Government has unveiled an ambitious retrofit programme that seeks significant improvement to the energy efficiency of the housing stock. High quality data on the energy efficiency of buildings and their related energy demand is critical to supporting and targeting investment in energy efficiency. Using existing home improvement programmes over the past 15 years, the UK Government has brought together data on energy efficiency retrofits in approximately 13 million homes into the Homes Energy Efficiency Database (HEED), along with annual metered gas and electricity use for the period of 2004–2007. This paper describes the HEED sample and assesses its representativeness in terms of dwelling characteristics, the energy demand of different energy performance levels using linked gas and electricity meter data, along with an analysis of the impact retrofit measures has on energy demand. Energy savings are shown to be associated with the installation of loft and cavity insulation, and glazing and boiler replacement. The analysis illustrates this source of ‘in-action’ data can be used to provide empirical estimates of impacts of energy efficiency retrofit on energy demand and provides a source of empirical data from which to support the development of national housing energy efficiency retrofit policies. - Highlights: • The energy efficiency level for 50% of the British housing stock is described. • Energy demand is influenced by size and age and energy performance. • Housing retrofits (e.g. cavity insulation, glazing and boiler replacements) save energy. • Historic differences in energy performance show persistent long-term energy savings

    Chemical pollutants and ventilation rate have been measured in newly built energy efficient private dwellings. The samples were taken in the absence of normal human activity in the houses. The data show that the main source of organic pollutants seems to be indoor building materials and furniture. For dust an important source could be the outdoor environment. Formaldehyde was primarily found in houses where chipboard was used while levels of radondaughters was very low in all houses tested. (Author)

    1991-03-01

    Since 1989, the U.S. Department of Energy has sponsored the Energy Efficient Industrialized Housing research program (EEIH) to improve the energy efficiency of industrialized housing. Two research centers share responsibility for this program: The Center for Housing Innovation at the University of Oregon and the Florida Solar Energy Center, a research institute of the University of Central Florida. Additional funding is provided through the participation of private industry, state governments and utilities. The program is guided by a steering committee comprised of industry and government representatives. This report summarizes Fiscal Year (FY) 1990 activities and progress, and proposed activities for FY 1991 in Task 2.1 Design for Energy Efficiency. This task establishes a vision of energy conservation opportunities in critical regions, market segments, climate zones and manufacturing strategies significant to industrialized housing in the 21st Century. In early FY 1990, four problem statements were developed to define future housing demand scenarios inclusive of issues of energy efficiency, housing design and manufacturing. Literature surveys were completed to assess seven areas of influence for industrialized housing and energy conservation in the future. Fifty-five future trends were identified in computing and design process; manufacturing process; construction materials, components and systems; energy and environment; demographic context; economic context; and planning policy and regulatory context.

  15. Perspectives on implementing energy efficiency in existing Swedish detached houses

    International Nuclear Information System (INIS)

    Joelsson, Anna; Gustavsson, Leif

    2008-01-01

    In this study, we first analyse energy-efficiency measures in existing electrically heated houses in Sweden from a societal economic perspective. Measures to a house envelopes and to energy supply chains are evaluated through a system analysis approach and we include the external costs of climate change and the effect of different Swedish climatic zones. We find that in a typical house from the 1970s, conversion from electric heating is highly motivated since the mitigation cost of conversion is lower than the estimated external costs of emitted CO 2 . Both conversions and house envelope measures are more motivated in the northern part of the country, where there is a higher heat demand. A successful implementation of changes requires them to be attractive for consumers to adopt. We therefore secondly analyse the economic conditions for Swedish house owners to implement societal economic cost-efficient measures. We include the economic influence of an investment subsidy for heating system conversion, an income tax deduction for changing windows, customer electricity tax, real estate tax and of the cost of purchased energy from different energy suppliers. Apart from the economics, several other factors affect a house owner's decision to change heating systems. We therefore thirdly analyse house owners' perceptions of different heating supply alternatives based on the results of two comprehensive questionnaires. These different perspectives are combined in a discussion whether the studied policy instruments encourage house owners to implement changes in accordance with the energy-efficiency goals of decision makers. We find that the investment subsidy could be useful to break the lock-in effect of resistance heaters, which house owners seemed to experience. The electricity tax makes heating systems in line with national goals more competitive and efficiency measures to the house envelope more profitable. The reduction of the electricity tax in the northern part of

    2010-01-01

    This paper describes an energy-efficient housing stimulus strategy that can: (1) quickly provide large-scale job creation; (2) reduce home energy bills by 30-50% with associated reductions in emissions and energy assistance spending; (3) stabilize home values and reduce foreclosure inventory; (4) help to eliminate childhood lead poisoning; and (5) implement regulatory reforms that highlight market incentives for cost effective energy efficiency and alternative home energy investments. These benefits, far in excess of costs, can be achieved by combining 'lead-safe window replacement' with other weatherization activities and simple regulatory and market reforms. This strategy can help to coordinate American Recovery and Reinvestment Act funding for energy efficiency, the $75 billion Making Home Affordable plan to reduce foreclosures, and the recently announced partnership between the Departments of Energy (DOE) and Housing and Urban Development (HUD) to streamline weatherization efforts and spur job creation.

  17. The price of energy efficiency in the Spanish housing market

    2016-01-01

    The housing sector is a substantial consumer of energy, and therefore a focus for energy savings efforts. The Energy Performance of Buildings Directive (EPBD), introduced in 2002 and revised in 2010, is a key instrument to increase the energy performance of buildings across the European Union. Following the implementation of the EPBD into Spanish law, all properties offered for sale or rented out in Spain are required to have an Energy Performance Certificate (EPC). Given that the implementation of the EPC scheme for new, existing and advertised properties is still very low in Spain, unlike other European housing markets, the Spanish one lacks market data on energy efficiency (EE) labels and their impact on housing price. To overcome this gap, we determine the EE ratings of a sample of 1507 homes across Spain on the basis of information collected previously through household surveys. This allowed us to answer the question of whether or not, and to what extent, Spanish housing markets capitalise the value of EE. We apply the hedonic-price technique and observe that more energy efficient dwellings have a price-premium between 5.4% and 9.8% compared to those with the same characteristics but lower EE level. - Highlights: •The Spanish housing market lacks data on energy efficiency (EE) labels. •We determine the EE ratings of a sample of 1507 homes across Spain. •Homes labelled A, B and C account for less than 10% of the housing stock. •Energy efficient dwellings have a price-premium between 5.4% and 9.8%, ceteris paribus.

  18. Promoting Behavior-Based Energy Efficiency in Military Housing

    1999-09-07

    The U.S. Department of Energy's Federal Energy Management Program (FEMP) helps agencies reduce the cost of doing business through energy efficiency, water conservation, and the use of solar and other renewable energy. As a large energy user, the U.S. military has been one of the government sectors of focus. Several military installations have shown substantial energy savings in past years. Most of these efficiency projects, however, have focused primarily on physical upgrades, technologies, and purchasing habits. Furthermost projects have focused on administrative and operational areas of energy use. Military residential housing, in particular, has received little formal attention for energy efficiency involving behaviors of the residents themselves. Behavior-based change is a challenging, but potentially fruitful area for energy conservation programs. However, behavioral change involves links with values, social networks and organizations, and new ways of thinking about living patterns. This handbook attempts to fill a gap by offering guidance for promoting such efforts.

    South Africa aims to build 3 million houses in the next six years. The most energy efficient design has to be identified to ensure the optimal use of South Africa's resources and to create a prosperous environment for her inhabitants. For this purpose the various formal low-cost house concepts on the market were evaluated and the projected impact on the country calculated. Houses were evaluated by means of a computer programme, Quick. Through simulations it was found that the common brick building built according to passive design guidelines is the best performer. The difference between the best and worst performer accounts to predicted direct cumulative savings in energy costs for a country like South Africa of over R180 million (US dollars 72 million) per annum.

  20. Refurbishment of a Victorian terraced house for energy efficiency

    Science.gov (United States)

    Dimitriou, Angeliki

    The impacts of global warming are now obvious. The international community has committed itself to reduce CO2 emissions, the main contributor to the greenhouse effect, both at international and national levels. In the Kyoto Protocol signed in 1997, countries have committed to reduce their greenhouse gases emissions below their 1990 levels by the period 2008-2012. The UK specifically should reduce those emissions by 12.5%. Format reason, the UK has introduced a package of policies, which promote not only the use of renewable energy resources, but most importantly the reduction in energy use, with energy efficiency. Refurbishment of existing houses has and will contribute to the reduction of energy consumption. A Victorian mid-terraced house was studied in this report, and different refurbishment measures were tested, using two software programmes: TAS and SAP. The targets were to achieve certain levels of thermal comfort, to comply with the Building Regulation for building thermal elements and to achieve a high SAP rating. Then, the cost of each measure was calculated and its CO2 emissions were compared. Heat losses were mainly through the walls and roof. Roof and mainly wall refurbishment measures reduce the heating loads the most. Ground floor insulation does not contribute to the reduction of the heating loads, on the contrary it has detrimental effect in summer, where the cooling effect coming from the ground is being reduced. Window replacement achieves a very good performance in summer resulting in the reduction of overheating. Wall and roof insulation increase the SAP rating the most, between the building elements, but boiler replacement and upgrading of heating controls increase it more. According to the SAP rating, CO2 annual emissions are reduced the most by boiler replacement and then by wall and roof. The results given by the two softwares concerning which measure is more leads more to energy efficiency, are the same. Finally, if the measures which lead

    Houses built in New England within the last six years, equal to or exceeding energy-efficiency standards from Energy Crafted Homes (ECH) or from DOE's Energy Star Homes are termed energy-efficient for this study. An assumption is that people who purchase houses being newly constructed may request special features including more energy-efficient features. The average house being constructed today is not as energy-efficient as it could easily be; therefore, owners of recently constructed energy-efficient houses may be termed early-adopters of an innovation. It has been demonstrated that early adopters have different personal attitudes and perceptions of an innovation compared to later-adopters. Both types of adopters--owners of recently constructed energy-efficient or energy-inefficient houses, have been surveyed in New England to determine whether their differences are significant enough to be used in identifying future potential early-adopters. Solar houses also are usually energy-efficient, and should be termed an innovation

    This research program addresses the need to increase the energy efficiency of industrialized housing. Two research centers have responsibility for the program: the Center for Housing Innovation at the University of Oregon and the Florida Solar Energy Center, a research institute of the University of Central Florida. The two organizations provide complementary architectural, systems engineering, and industrial engineering capabilities. In 1989 we worked on these tasks: (1) the formation of a steering committee, (2) the development of a multiyear research plan, (3) analysis of the US industrialized housing industry, (4) assessment of foreign technology, (5) assessment of industrial applications, (6) analysis of computerized design and evaluation tools, and (7) assessment of energy performance of baseline and advanced industrialized housing concepts. The current research program, under the guidance of a steering committee composed of industry and government representatives, focuses on three interdependent concerns -- (1) energy, (2) industrial process, and (3) housing design. Building homes in a factory offers the opportunity to increase energy efficiency through the use of new materials and processes, and to increase the value of these homes by improving the quality of their construction. Housing design strives to ensure that these technically advanced homes are marketable and will meet the needs of the people who will live in them.

    Housing is a problem in all developing countries. Presently South Africa has a large urbanization drive, to such an extent that over the next 10 years 1300 houses per day must be built to alleviate the problem. Most of the houses currently being erected could be described as ultra-low-cost houses. These houses are constructed by their owners in record time from corrugated iron. Advantages are the accessibility of building material and straightforward building techniques. Unfortunately the dwellings are thermally and energy inefficient. As a result inhabitants spend a disproportionate percentage of their income on winter heating. They use highly polluting and low energy content fuels such as wood and coal. This presents health risks and burdens the environment and natural resources. This paper evaluates the potential of inexpensive modifications which contribute to improved living and environmental conditions. Investigations are based on a unique analysis method which is eminently suitable for application to the problem. Modifications such as cardboard insulation showed the most potential. Although often available free of charge as waste products, results indicate that a definite cost saving incentive exists even if owners have to buy the cardboard. Modifying the houses as suggested reduces energy requirements and the release of greenhouse gases into the atmosphere by up to 75%. (author)

    This paper investigates the energy efficiency in a segment of the building sector in emerging countries by analyzing and evaluating the energy efficiency of a social housing project in Brazil. Energy efficiency measures and bioclimatic design strategies are developed in order to improve thermal comfort in this social housing project and to reduce the energy consumption and expenses of their residents. The institutional barriers and constraints toward higher efficiency are described. The results of this study show that there is a high potential to increase energy efficiency in social housing in emerging countries like Brazil. The implementation and consideration of the energy efficiency measures and policy recommendations would contribute substantially to the goal to dampen the fast growth of energy demand in these countries. Moreover the improvement of energy efficiency in the social housing sector could be a driver for market transformation towards more sustainability in the whole building sector. - Research highlights: →There is a high potential to increase energy efficiency in social housing in Brazil. →Energy-efficient social housing would contribute substantially to dampen the fast growth of energy consumption in emerging countries like Brazil. →Implementation of energy efficiency would improve the income situation of the poorest strata of the population.

    A large percentage of South Africa`s population is at present housed in low-cost dwellings. Furthermore, more than 2 million new houses must be built over the next 10 years to alleviate the current housing shortage. Unfortuanately the existing houses are very energy inefficient and if nothing is done now, the new houses will surely also be inefficient. It would have a tremendous impact on the inhabitant`s disposable income, health as well as their environment if these low-cost houses could be made energy efficient. This prompted the authors to investigate retrofit options to improve the energy efficiency of existing houses and to evaluate energy efficiency design concepts for new houses. The energy efficiency of the improvements was evaluated by means of computer simulations. Ceiling insulation was found to be the best retrofit for the typical formal low-cost house. By retrofitting existing formal low-cost houses with insulation integrated ceilings the Gauteng region could save Dollar 12 million in electricity costs per year and Dollar 0.79 billion in peak demand electricity supply. If the proposed new houses are supplied with insulation integrated ceilings the Gauteng region could save approximately Dollar 2 million in electricity costs per year and Dollar 224 million in peak demand electricity supply.

    This article offers an impression of the problems related to the limited financial options for energy efficient buildings and dwellings and possible solutions. It is based on a recent ECN study (RE-BIZZ) and several interviews about this topic with financers. There is a need for a more business appreciation of market parties such as financers for energy efficiency in buildings to increase financing options. The market needs the help of the government, which can help to remove barriers and hence make financing more appealing. [nl

    This paper presents work in progress in `Design for Energy Efficiency`, one of fifteen task areas within the United States Department of Energy sponsored Energy Efficient Industrialized Housing (EEIH) research program. In this task area, the design, engineering and manufacturing disciplines of the program seek to generate an agenda of energy related research and development priorities from visions of industrialized housing systems for the year 2030. Of the several housing and energy demand scenarios explored, this paper illustrates one -- a low cost concrete panel system for housing at multi-family densities in hot arid, cooling dominated climates (Arizona). This particular scenario explores the opportunity of industrialized technologies to passively condition housing in this context. Aspects of both the long term vision -- as system performance specifications, and the short term research priorities -- as a roster of proposed research activities, are presented.

    One of the primary goals of the US Department of Housing and urban Development (HUD) is the expansion of home ownership and affordable housing opportunities. Recognizing that energy efficiency is a key component in an affordable housing strategy, HUD and the US Department of Energy (DOE) created the DOE-HUD Initiative on Energy Efficiency in Housing. The DOE-HUD Initiative was designed to share the results of DOE research with housing providers throughout the nation, to reduce energy costs in federally-subsidized dwelling units and improve their affordability and comfort. This Program Summary Report provides an overview of the DOE-HUD Initiative and detailed project descriptions of the twenty-seven projects carried out with Initiative funding.

    A five-year initiative between the US Department of Energy (DOE) and the US Department of Housing and Urban Development (HUD) demonstrated the feasibility of improving the energy efficiency of publicly-assisted housing. Twenty-seven projects and activities undertaken during 1990--95 involved research and field demonstrations, institutional and administrative changes to HUD policies and procedures, innovative financing and leveraging of federal dollars with non-federal money, and education, training, and technical assistance. With most of the 27 projects and activities completed, the two departments have initiated a five-year deployment effort, the DOE-Energy Partnerships for Affordable Homes, to achieve energy and water savings in public and assisted housing on a large scale throughout the country. A Clearinghouse for Energy Efficiency in Public and Assisted Housing managed by the National Center for Appropriate Technology (NCAT), will offer hands-on energy assistance to housing providers to complement DOE`s assistance. This paper presents the findings of the DOE-HUD Initiative, with primary attention paid to those projects which successfully integrated energy efficiency into private and public single and multifamily housing. The paper includes examples of the publications, case-study reports, exhibits and videotapes developed during the course of the Initiative. Information on the new DOE Energy Partnerships and on the NCAT Clearinghouse is also presented. New Partnership projects with the Atlanta and Chicago Housing Authorities describe the technical assistance envisioned under the Partnership.

    Houses designed for one climate and cultural group may not be appropriate for other places and people. Our aim is to find cost-effective ways to improve the characteristics of older homes, ill-fitted for New Zealand's climate, in order to improve the occupants' health. We have carried out two community randomised trials, in partnership with local communities, which have focused on retrofitted insulation and more effective heating and have two other studies under way, one which focuses on electricity vouchers and the other on housing hazard remediation. The Housing, Insulation and Health Study showed that insulating 1,350 houses, built before insulation was required, improved the occupants' health and well being as well as household energy efficiency. In the Housing, Heating and Health Study we investigated the impact of installing more effective heating in insulated houses for 409 households, where there was a child with doctor-diagnosed asthma. Again, the study showed significant results in the intervention group; indoor temperatures increased and levels of NO(2) were halved. Children reported less poor health, lower levels of asthma symptoms and sleep disturbances by wheeze and dry cough. Children also had fewer days off school. Improving the energy efficiency of older housing leads to health improvements and energy efficiency improvements. Multidisciplinary studies of housing interventions can create compelling evidence to support policies for sustainable housing developments which improve health.

  20. Governance, technology, and equity: An integrated policy framework for energy efficient housing

    2012-01-01

    Transforming the housing stock to a low energy performance is a key priority in the context of sustainable development and a post-carbon transition. However, in terms of its practical implementation it, firstly, faces a number of complex institutional barriers, while, secondly, involves a risk of being dominated by a narrow technocratic agenda for energy/carbon reduction that may overtake the socially progressive pursuits of housing policy. Energy efficiency strategies for the residential sector must, therefore, be multidimensional, fully synergised with housing policy, and incorporating the principles of equity, access and a balanced geographical development. This paper discusses a strategic policy framework, which was designed by the United Nations Economic Commission for Europe (UNECE) to address those important needs in international policy. The document – Action Plan for Energy-efficient Housing in the UNECE Region – outlines a number of goals, targets and actions structured at three dimensions: (i) governance and finance, (ii) technological advancement, and (iii) access and affordability. The Action Plan provides a comprehensive and integrated framework, based on which governments can shape their own pathways towards a sustainable low-energy residential sector. - Highlights: ► Residential sector has a large potential for energy and carbon reduction. ► Energy efficiency for housing must be reconciled with socially oriented housing policy. ► Action Plan for Energy-efficient Housing in the UNECE region is presented. ► The Plan offers an integrated framework for sustainable transition to low-energy housing. ► Governance, technology, and equitable access are three key elements of the framework.

  3. Improving health, safety and energy efficiency in New Zealand through measuring and applying basic housing standards.

    2013-08-02

    Substandard housing is a problem in New Zealand. Historically there has been little recognition of the important aspects of housing quality that affect people's health and safety. In this viewpoint article we outline the importance of assessing these factors as an essential step to improving the health and safety of New Zealanders and household energy efficiency. A practical risk assessment tool adapted to New Zealand conditions, the Healthy Housing Index (HHI), measures the physical characteristics of houses that affect the health and safety of the occupants. This instrument is also the only tool that has been validated against health and safety outcomes and reported in the international peer-reviewed literature. The HHI provides a framework on which a housing warrant of fitness (WOF) can be based. The HHI inspection takes about one hour to conduct and is performed by a trained building inspector. To maximise the effectiveness of this housing quality assessment we envisage the output having two parts. The first would be a pass/fail WOF assessment showing whether or not the house meets basic health, safety and energy efficiency standards. The second component would rate each main assessment area (health, safety and energy efficiency), potentially on a five-point scale. This WOF system would establish a good minimum standard for rental accommodation as well encouraging improved housing performance over time. In this article we argue that the HHI is an important, validated, housing assessment tool that will improve housing quality, leading to better health of the occupants, reduced home injuries, and greater energy efficiency. If required, this tool could be extended to also cover resilience to natural hazards, broader aspects of sustainability, and the suitability of the dwelling for occupants with particular needs.

    In FY1999, Pacific Northwest National Laboratory conducted an energy efficiency campaign for residential housing at the Fort Lewis Army Installation near Tacoma, Washington. Preliminary weather-corrected calculations show energy savings of 10{percent} from FY98 for energy use in family housing. This exceeded the project's goal of 3{percent}. The work was funded by the U.S. DOEs Federal Energy Management Program (FEMP), Office of Energy Efficiency and Renewable Energy. The project adapted FEMP's national ``You Have the Power Campaign'' at the local level, tailoring it to the military culture. The applied research project was designed to demonstrate the feasibility of tailored, research-based strategies to promote energy conservation in military family housing. In contrast to many energy efficiency efforts, the campaign focused entirely on actions residents could take in their own homes, as opposed to technology or housing upgrades. Behavioral change was targeted because residents do not pay their own utility bills; thus other motivations must drive personal energy conservation. This campaign augments ongoing energy savings from housing upgrades carried out by Fort Lewis. The campaign ran from September 1998 through August 1999. The campaign strategy was developed based on findings from previous research and on input from residents and officials at Fort Lewis. Energy use, corrected to account for weather differences, was compared with the previous year's use. Survey responses from 377 of Fort Lewis residents of occupied housing showed that the campaign was moderately effective in promoting behavior change. Of those who were aware of the campaign, almost all said they were now doing one or more energy-efficient things that they had not done before. Most people were motivated by the desire to do the right thing and to set a good example for their children. They were less motivated by other factors.

    2015-07-09

    Five Steps to Implementing the PHA Energy Efficient Unit Turnover Package (ARIES, 2014) is a guide to prepare for the installation of energy efficient measures during a typical public housing authority unit turnover. While a PHA is cleaning, painting and readying a unit for a new resident, there is an opportunity to incorporate energy efficiency measures to further improve the unit's performance. The measures on the list are simple enough to be implemented by in-house maintenance personnel, inexpensive enough to be folded into operating expenses without needing capital budget, and fast enough to implement without substantially changing the number of days between occupancies, a critical factor for organizations where the demand for dwelling units far outweighs the supply. The following guide lays out a five step plan to implement the EE Unit Turnover Package in your PHA, from an initial Self-Assessment through to Package Implementation.

    Typical approaches for assessing energy efficiency potential in buildings use a limited number of prototypes, and therefore suffer from inadequate resolution when pass-fail cost-effectiveness tests are applied, which can significantly underestimate or overestimate the economic potential of energy efficiency technologies. This analysis applies a new approach to large-scale residential energy analysis, combining the use of large public and private data sources, statistical sampling, detailed building simulations, and high-performance computing to achieve unprecedented granularity - and therefore accuracy - in modeling the diversity of the single-family housing stock. The result is a comprehensive set of maps, tables, and figures showing the technical and economic potential of 50 plus residential energy efficiency upgrades and packages for each state. Policymakers, program designers, and manufacturers can use these results to identify upgrades with the highest potential for cost-effective savings in a particular state or region, as well as help identify customer segments for targeted marketing and deployment. The primary finding of this analysis is that there is significant technical and economic potential to save electricity and on-site fuel use in the single-family housing stock. However, the economic potential is very sensitive to the cost-effectiveness criteria used for analysis. Additionally, the savings of particular energy efficiency upgrades is situation-specific within the housing stock (depending on climate, building vintage, heating fuel type, building physical characteristics, etc.).

    In this report preliminary criteria for energy-efficient houses (PH) for professional buildings are presented. The term 'professional building' includes the eleven building categories in TEK 07 (Norwegian building regulations for passive houses) apart from the two housing categories: smaller dwellings and apartment buildings. Criteria have also been proposed for low-energy houses, with levels between today's regulations and passive house levels. In the suggested standard there are requirements for net heating needs, net cooling needs, heat loss figures and carbon dioxide emissions. The requirements comply with the passive house standard NS 3700 for dwellings under construction. Minimum requirements for components have also been proposed. In addition there are recommended values for additional internal heat and air quantities, based on the best available technology today. Comprehensive enclosures include detailed support on how the criteria have been developed. These preliminary criteria could also be applied in Enova's work on good example projects on PH and LE -levels, and also form the basis for a standard for professional buildings which supplements the coming NS 3700.

    This project represents the third phase of a multi-year effort to develop and bring to market a High Performance Manufactured Home (HPMH). In this project, the Northwest Energy Efficient Manufactured Housing Program worked with Building America Partnership for Improved Residential Construction and Bonneville Power Administration to help four factory homebuilders build prototype zero energy ready manufactured homes, resulting in what is expected to be a 30% savings relative to the Building America Benchmark. (The actual % savings varies depending on choice of heating equipment and climate zone). Previous phases of this project created a HPMH specification and prototyped individual measures from the package to obtain engineering approvals and develop preliminary factory construction processes. This case study describes the project team's work during 2014 to build prototype homes to the HPMH specifications and to monitor the homes for energy performance and durability. Monitoring is expected to continue into 2016.

Understanding the characteristics of housing groups referred to as "archetypes" by vintage, style, and construction characteristics can allow research teams to focus their retrofit research and develop prescriptive solutions for those structure types which are prevalent and offer high potential uptake within a region or market.

  14. Leveraging energy efficiency to finance public-private social housing projects

    International Nuclear Information System (INIS)

    Copiello, Sergio

    2016-01-01

    The Italian housing model relies on a high rate of privately owned houses. In comparison, few dwellings are built and managed by the public sector. The social housing stock has been built mainly during some post-second world war decades; instead, since the early nineties, it underwent a privatization process. Such a model is inefficient and iniquitous in the long run. Therefore, after being disregarded for several years, social housing has gone back to be among the main agenda items. Nonetheless, due to the lack of public grants, new funding sources are required. The government now fosters an increasing involvement of private finance through Public-Private Partnership schemes. A first outcome can be found in some pioneering experiences. Their comparative analysis allows bringing out worthwhile findings, which are useful to steer housing policies. Moderate to low yields entail the need to involve new kinds of private entities, particularly those adopting a venture philanthropy approach. Meanwhile, building energy performance measures are a crucial driver of feasibility. They allow the tenants to be willing to pay agreed rents somehow higher than both social rents of protected tenancies and fair rents of regulated tenancies. - Highlights: •In Italy, the provision of affordable dwellings was disregarded for years. •Recently, instead, social housing has come back to be among the main agenda items. •Latest regulations try to tie together social housing and Public-Private Partnership. •Social tenants may be asked to pay more than in protected and regulated tenancies. •Energy-efficient measures allow keeping the tenants neutral about the rent increase.

    The Building America Partnership for Improved Residential Construction, the Bonneville Power Administration (BPA), and Northwest Energy Works (NEW), the current Northwest Energy Efficient Manufactured Housing Program (NEEM) administrator, have been collaborating to conduct research on new specifications that would improve on the energy requirements of a NEEM home. In its role as administrator, NEW administers the technical specs, performs research and engineering analysis, implements ongoing construction quality management procedures, and maintains a central database with home tracking. This project prototyped and assessed the performances of cost-effective high performance building assemblies and mechanical systems that are not commonly deployed in the manufacturing setting. The package of measures is able to reduce energy used for space conditioning, water heating and lighting by 50 percent over typical manufactured homes produced in the northwest.

    Beginning in 2008, two pairs of energy-saver houses were built at Wolf Creek in Oak Ridge, TN. These houses were designed to maximize energy efficiency using new ultra-high-efficiency components emerging from ORNL s Cooperative Research and Development Agreement (CRADA) partners and others. The first two houses contained 3713 square feet of conditioned area and were designated as WC1 and WC2; the second pair consisted of 2721 square feet conditioned area with crawlspace foundation and they re called WC3 and WC4. This report is focused on the annual energy performance of WC3 and WC4, and how they compare against a previously benchmarked maximum energy efficient house of a similar footprint. WC3 and WC4 are both about 55-60% more efficient than traditional new construction. Each house showcases a different envelope system: WC3 is built with advanced framing featured cellulose insulation partially mixed with phase change materials (PCM); and WC4 house has cladding composed of an exterior insulation and finish system (EIFS). The previously benchmarked house was one of three built at the Campbell Creek subdivision in Knoxville, TN. This house (CC3) was designed as a transformation of a builder house (CC1) with the most advanced energy-efficiency features, including solar electricity and hot water, which market conditions are likely to permit within the 2012 2015 period. The builder house itself was representative of a standard, IECC 2006 code-certified, all-electric house built by the builder to sell around 2005 2008.

    As concern over the environment grows, builders have the potential to fulfill a market niche by building homes that use fewer resources and have lower environmental impact than conventional construction. Builders can increase their marketability and customer satisfaction and, at the same time, reduce the environmental impact of their homes. However, it takes dedication to build environmentally sound homes along with a solid marketing approach to ensure that customers recognize the added value of energy and resource efficiency. This guide is intended for builders seeking suggestions on how to improve energy and resource efficiency in their new homes. It is a compilation of ideas and concepts for designing, building, and marketing energy- and resource-efficient homes based on the experience of recipients of the national Energy Value Housing Award (EVHA).

    Full Text Available Global increases in the demand for energy are imposing strong pressures over the environment while compromising the capacity of emerging economies to achieve sustainable development. In this context, implementation of effective strategies to reduce consumption in residential buildings has become a priority concern for policy makers as minor changes at the household scale can result in major energy savings. This study aims to contribute to ongoing research on energy consumer profiling by exploring the forecasting capabilities of discrete socio-economic factors that are accessible through social housing allocation systems. Accordingly, survey data gathered by the Chilean Ministry of Social Development was used identify key characteristics that may predict firewood usage for space heating purposes among potential beneficiaries of the Chilean social housing program. The analyzed data evidences strong correlations between general household characteristics and space heating behavior in certain climatic zones, suggesting that personalized delivery of energy efficiency measures can potentially increase the effectiveness of initiatives aimed towards the reduction of current patterns of consumption.

  4. Energy-Efficiency Retrofits in Small-Scale Multifamily Rental Housing: A Business Model

    Science.gov (United States)

    DeChambeau, Brian

    The goal of this thesis to develop a real estate investment model that creates a financial incentive for property owners to perform energy efficiency retrofits in small multifamily rental housing in southern New England. The medium for this argument is a business plan that is backed by a review of the literature and input from industry experts. In addition to industry expertise, the research covers four main areas: the context of green building, efficient building technologies, precedent programs, and the Providence, RI real estate market for the business plan. The thesis concludes that the model proposed can improve the profitability of real estate investment in small multifamily rental properties, though the extent to which this is possible depends partially on utility-run incentive programs and the capital available to invest in retrofit measures.

  5. Analyse of possibilities of increasing housing energy efficiency by application of phase-changing materials

    2009-01-01

    Full Text Available Refurbishment of existing building stock using energy-saving phase-changing smart materials and technologies, in addition to improved indoor climatic conditions, offer an opportunity for increasing housing energy efficiency and value. This fast developing technology becomes increasingly cost-effective with much shorter payback periods. However, it is undertaken only on a limited scale; because of lack of knowledge about their changeable properties and dynamism in that they behave in response to energy fields. Main characteristics, which make them different form others, are: immediacy transience, self-actuation, selectivity and directness. Phase change processes invariably involve the absorbing, storing or releasing of large amounts of energy in the form of latent heat. These processes are reversible and phase-changing materials can undergo an unlimited number of cycles without degradation. Since phase-changing materials can be designed to absorb or release energy at predictable temperatures, they have naturally been explored for use in architecture as a way of helping deal with the thermal environment in a building. Technologies based on sealing phase-changing materials into small pellets have achieved widespread use in connection with radiant floor heating systems, phase change wallboards, mortar or facade systems. Thermal characteristics of existing buildings can be improved on increasing their thermal-stored mass by implementation products of phase-changing smart materials. In addition to contributing to carbon reduction and energy security, using phase-changing materials in the building sector stimulates innovations.

    1997-09-01

    The New York Power Authority (NYPA) and the New York City Housing Authority (NYCHA) are replacing refrigerators in New York City public housing with new, highly energy-efficient models over a five-year period. This report describes the analysis of the energy cost savings achieved through the replacement of 20,000 refrigerators in 1996, the first year of the NYPA/NYCHA program. The NYPA/NYCHA project serves as the lynchpin of a larger program designed to offer energy-efficient appliances to housing authorities across the country. The national program is a partnership between the U.S. Department of Energy (DOE) and the Consortium for Energy Efficiency (CEE). Starting with the 1997 refrigerator contract, this program invites other housing authorities to join NYPA in its volume purchase of energy-efficient refrigerators, at the same price and terms available to NYPA. Through these volume purchases, DOE`s ENERGY STAR{reg_sign} Partnerships program hopes to encourage appliance manufacturers to bring more efficient appliances to the market and to provide volume purchasers with the per-unit price savings of a bulk purchaser. DOE asked the Pacific Northwest National Laboratory (PNNL) to establish a protocol for evaluating the savings achieved with the NYPA refrigerators. That protocol is summarized in this report.

    ?This project represents the third phase of a multi-year effort to develop and bring to market a High Performance Manufactured Home (HPMH). The scope of this project involved building four HPMH prototypes, resulting in what is expected to be a 30% savings relative to the Building America Benchmark. (The actual % savings varies depending on choice of heating equipment and climate zone). The HPMH home is intended to make significant progress toward performing as zero-net-energy ready. Previous phases of this project created a HPMH specification and prototyped individual measures from the package to obtain engineering approvals and develop preliminary factory construction processes. This report describes the project team's work during 2014 to build prototype homes to the HPMH specifications and to monitor the homes for energy performance and durability during 2014. Monitoring is expected to continue into 2016.

    Burholt, Vanessa; Windle, Gill

    2006-01-01

    This paper examines a representative sample (N=421) of older people (aged 70+) living in rural North Wales with regard to relationships between fuel poverty, feeling cold in one's home and a range of self-reported housing and home energy efficiency items. In the Welsh context, the combination of poor housing stock and low-level income is likely to increase the chance of older people experiencing fuel poverty, therefore the analyses are relevant to both energy and social policy. The paper hypothesises that: (i) People in 'fuel poor' homes are: low-income households; living in older houses; lacking home energy efficiency measures; (ii) not all people facing difficulties heating their home (i.e. wearing extra clothing to keep warm during cold spells) are identified as 'fuel poor', but there will be an association between taking extra measures to keep warm and low income; older houses and lacking home energy efficiency factors. The results partially support the hypotheses. An estimation is made of the expenditure required to counter the factors associated with fuel poverty and cold homes in the region. The paper concludes with implications for the UK Fuel Poverty Strategy

    2011-01-01

    Much focus is given to the energy efficiency of dwellings, in policy and regulation, in pursuance of reduced CO 2 emissions for sustainability. This article examines a terrace of 6 similar, passive solar dwellings with sunspaces and the effects that occupants' behaviours have on their energy efficiency. It was found that average annual space heating demand was less than expected, indicating potential benefits from measuring passive solar gains as a form of renewable energy. Space heating demand per person varied by a factor of up to 14 between dwellings dependent on occupant behaviour. Further evidence showed a factor of 45 possible. Significant behaviours in this dwelling type were identified. A second study used 31 personal ecological footprint (PEF) accounts to assess the significance of dwelling energy efficiency in terms of environmental sustainability. A comparison was made between residents of contemporary eco-homes and practising permaculturists occupying a range of traditional house types. It was found that the PEF of the average eco-home dweller was 1.6 times higher than that of the permaculturists. It is argued that improved education for sustainability would be a more efficient way to reduce domestic energy demand than currently recognised. - Highlights: → Quantifies improvements to dwelling energy efficiency from behaviour and education. → Assesses balance of dwelling energy efficiency and sustainability. → Suggests education for sustainability be used more to reduce energy demand. → Indicates research directions to assess budgets for education in sustainability. → Identifies significant behaviour affecting energy efficiency with sunspace use.

  11. Barriers and opportunities for improving energy efficiency in the social housing sector: Case study of E4C's Division of Housing and Mental Health

    Science.gov (United States)

    Marchand-Smith, Patrick

    Energy efficiency improvements in the social housing sector have the potential to produce a range of environmental and social benefits. These improvements can be produced through retrofits that deliver energy savings or new construction built to a high standard of energetic efficiency. However, implementation of these approaches is hindered by economic and organizational constraints affecting the agencies that provide society with social housing and the governments that support the provision of these services. This thesis builds on the work of other researchers studying these constraints by supplying an in-depth case study from Alberta and a discussion based on its findings. The case study focuses on E4C, a social service agency with several housing projects. Overall, findings matched important themes identified in the academic literature. The in-depth nature of the case study added additional insight to many of these themes. Most barriers are economic in nature and related to a lack of sufficient funding or the up-front costs of energy-saving retrofits. The recommendations presented are based on consideration of the multiple barriers and opportunities faced. Most of these require a considerable investment of time on the part of agencies and would be followed up by capital investments to implement energy-saving changes. Therefore it is important to note that the most significant barrier is commitment, which is one of E4C's central values. This thesis showed that commitment cannot exceed capacity to act. Greater commitment on the part of governments, agencies or society at large could have significant impacts in improving the energy efficiency of buildings in the Albertan, and Canadian, social housing sector.

    Full Text Available With the increase in energy consumption by buildings in keeping the indoor environment within the comfort levels and the ever increase of energy price there is need to design buildings that require minimal energy to keep the indoor environment within the comfort levels. There is need to predict the indoor temperature during the design stage. In this paper a statistical indoor temperature prediction model was developed. A passive solar house was constructed; thermal behaviour was simulated using ECOTECT and DOE computer software. The thermal behaviour of the house was monitored for a year. The indoor temperature was observed to be in the comfort level for 85% of the total time monitored. The simulation results were compared with the measured results and those from the prediction model. The statistical prediction model was found to agree (95% with the measured results. Simulation results were observed to agree (96% with the statistical prediction model. Modeled indoor temperature was most sensitive to the outdoor temperatures variations. The daily mean peak ones were found to be more pronounced in summer (5% than in winter (4%. The developed model can be used to predict the instantaneous indoor temperature for a specific house design.

    2017-10-01

    Full Text Available Energy poverty is a common issue in social housing all over Europe, with a harder impact in Southern European countries. Social housing buildings play an important role in energy poverty. They are usually owned and managed by public institutions and usually share common characteristics and issues. Behavioural changes and energy retrofitting are interesting paths forward but some solutions do not fit well in this type of housing due to socioeconomic reasons. This paper makes a thorough analysis of possible energy efficiency measures in social housing buildings, characterizing them by energy and economic savings and investment and proposing different methods of prioritization. A rational approach of behavioural and retrofitting solutions that best fit into this particular housing type is delivered, with the aim to increase the thermal comfort of the residents and mitigate the energy poverty issue. Results show that there is a wide range of domestic efficiency measures to be applied in this type of dwellings at none or low costs, bringing annual savings per average dwelling of about 510 €/year (55% of initial energy costs including measures both at domestic level, and at building level with a final aggregated payback of the investments to be about 1.5 years.

    International Nuclear Information System (INIS)

    Gilbertson, Jan; Grimsley, Michael; Green, Geoff

    2012-01-01

    Over the past decade the Warm Front Scheme has been the English Government's principal programme for improving domestic energy efficiency and reducing fuel poverty. This paper reports on a cross-sectional survey of low income householders participating in the Warm Front Scheme in five urban areas of England. Surveys were conducted of 2685 individuals, before and or after intervention. Pathways to self reported health were modelled by logistic regression. Of all the dimensions of health examined, only self reported mental health is directly associated with Warm Front measures. Intermediary variables associated with Warm Front intervention were shown to be significantly correlated with more dimensions of self reported health status. Higher temperatures, satisfaction with the heating system, greater thermal comfort, reductions in fuel poverty and lower stress were significantly correlated with improved health. Alleviating fuel poverty and reducing stress appeared to be the main route to health. We conclude there are complex and indirect relationships linking energy efficiency measures to outcomes on all dimensions of health which contribute to significant material and psychosocial benefits. The impact of the Warm Front Scheme cannot be fully understood by a limited analysis which merely relates indoor temperature and property characteristics to physiological health outcomes. - Highlights: ► Warm Front improvements are linked to significant material and psychosocial benefits. ► The alleviation of fuel poverty and the reduction of stress emerge as the likely route to health. ► The scope for improving health is greater than implied by the UK Government's Fuel Poverty Strategy. ► A dual but integrated approach to alleviating cold living conditions and fuel poverty is required.

    2016-01-01

    Full Text Available Russia’s GDP energy intensity today is approximately 2.5–3.5 times higher than that of economically developed countries. To increase its economic competitive ability, Russia needs to achieve energy efficiency in different spheres, including construction, housing and community amenities. Close examination of implemented management measures and world experience revealed that in order to achieve a further energy efficiency increase Russia needs to boost economic interest of the participants concerned and to form effective mechanisms of economic management, and this should be done along with improvement of administrative governance. The paper focuses on the barriers that hamper economic motivation and provides recommendations for energy efficiency increase. Even partial implementation of suggested measures, in our opinion, will increase energy efficiency in the spheres of construction and housing accommodation, which is illustrated through the example of a residential building located in Yekaterinburg (Russia, Middle Urals.

    Using DOE grant funds, the Alliance to Save Energy developed and managed an award-winning low-income housing demonstration in cooperation with Houston Habitat for Humanity at the 1996 and 1997 annual NAHB Builders Show in Houston, Texas. Using a unique group of over 30 national, state and local partners, the energy design of Houston Habitat houses was permanently upgraded to the Energy Star Homes Program threshold. Meeting Energy Star Homes Program criteria, the partner design team increased the level of efficiency approximately 30% over the 1992 Model Energy Code. This innovative design using commercially available materials added approximately $1,400 in cost-effective energy upgrades with an estimated payback of less than 8 years. The 30 public-private partners successfully demonstrated energy and resource efficient housing techniques to the 65,000 NAHB home show attendees and the over 3,000 Habitat affiliates. This project resulted in the Houston Habitat affiliate becoming the nation`s first low-income Energy Star Homes Program home builder. By the year 2000, Houston Habitat anticipates building over 500 homes to this new level of efficiency as well as set an example for other Habitat affiliates nationwide to follow. The 1997 demonstration house utilized an all-women volunteer builders team to construct a 3 bedroom home in Houston Habitat`s Woodglen Subdivision. Energy consumption was remotely metered by Texas A and M.

Predicted annual energy savings (over Salishan phase 6) was 19% for Salishan phase 7, and between 19-24% for the demonstration homes (depending on ventilation strategy). Approximately two-thirds of the savings are attributable to the DHP. Working with the electric utility provider, Tacoma Public Utilities, researchers conducted a billing analysis for Salishan phase 7.

    This project evaluates the renovation of a 5,800 ft2, multi-use facility located in St. Petersburg, on the west coast of central Florida, in the hot humid climate. An optimal package of retrofit measures was designed to deliver 30-40% annual energy cost savings for this building with annual utility bills exceeding $16,000 and high base load consumption. Researchers projected energy cost savings for potential retrofit measures based on pre-retrofit findings and disaggregated, weather normalized utility bills as a basis for simulation true-up. A cost-benefit analysis was conducted for the seven retrofit measures implemented; adding attic insulation and sealing soffits, tinting windows, improving whole building air-tightness, upgrading heating and cooling systems and retrofitting the air distribution system, replacing water heating systems, retrofitting lighting, and replacing laundry equipment. The projected energy cost savings for the full retrofit package based on a post-retrofit audit is 35%. The building's architectural characteristics, vintage, and residential and commercial uses presented challenges for both economic projections and retrofit measure construction.

    Energy is an essential factor to economic and social development and improved standards of living in developing countries. Nigeria in particular. There is a strong need for greater energy efficiency in every sector of economy in order to reduce costs. enhance competitiveness, conserve energy resources and reduce environmental impacts associated with production, distribution and use of energy. Energy auditing and monitoring has a significant role in any energy management and conservation project. Energy auditing as an important part of industrial energy management on plant level, represents a complex of activities aiming at the efficient use of energy. The activities are undertaken by a team of experts who use a set of measuring instruments to monitor and evaluate all the necessary data to elaborate a package of recommendations on improvements in the field of energy efficiency and possible product quality. The inefficient conversion and use of energy have been identified as a central problem for all developing countries, Nigeria inclusive, since they all consume significantly higher amounts of energy per unit of GDP than OECD countries. This aggravates energy-related environmental problems and is also a burden on domestic resources and foreign exchange. Energy prices have risen drastically in many developing countries, while energy intensities remain high. Price changes alone are not rapidly translating energy efficiency improvements. Identifying and removing the obstacles to greater energy efficiency should be priority for government in developing countries. This is why the Energy Commission, an apex organ of government on Energy matters in all its ramifications is out to encourage relatively low-cost energy audits for the Textile industries - such audits can identify ''good house-keeping's' measures, such as simply process improvements, that reduce energy consumption and operating costs. This will be followed by the training of plant workers/energy managers

    This paper describes a low-energy house in Zittau, Germany. The house consists of two parts A and B. Part A is heated by means of gas boilers and condensed boilers, while part B is solar heated. Energy for heating and warming of tap water is an important part of the primary energy consumption in Germany. Therefore, one way of reducing the CO2 emissions is to reduce the heat losses of buildings through outer facades and air ventilation, to use regenerative energy sources, to use fuels with low CO2 emissivity like natural gas, and to install efficient heating- and hot water preparation systems. The low-energy house in Zittau is used for energy research

  2. How does the European Regional Development Fund finance energy efficiency and renewable investments in housing sector in Bulgaria, Poland and Romania?

    International Nuclear Information System (INIS)

    2009-11-01

    The European Union (EU) is leading the global fight against climate change, and has made it a top priority. Its ambitious targets are spelt out in the EU Climate Action and Renewable Energy Package which commits Member States to curb their CO 2 emissions by at least 20% by 2020 through improved energy efficiency and use of renewable energy sources. The housing sector, responsible for 40% of the EU CO 2 emissions, represents a huge potential for energy and emissions savings. The policy at EU level is adopted and the facts are clear - we know in which sectors and how to act to achieve the common objectives. The EU even allocates some funds for EE/RES actions in housing sector, e.g. through the Cohesion policy. Since May 2009, all EU Member States can allocate 4% of their total ERDF allocations to energy efficiency measures in housing, in particular social housing. It would seem that all the conditions are favorable but the reality is different - EE/RES actions are still not the priority of the EU Member States and/or the European funds are rarely used for this type of actions. The case of three EU-12 countries - Bulgaria, Poland and Romania - proves that the Structural Funds available for improvement of housing and particularly social housing sector, are not fully used also for the following reasons: Housing and social housing are not the priorities or national budgets allocated to these sectors are not sufficient to co-finance projects supported by the Structural Funds: - In Romanian operational programs, (social) housing is mentioned very vaguely - eligible measures are not specified in details. - In Bulgaria, the priorities in the operational programs are well identified, however municipalities have difficulties to find even 5% co-financing for their EE/RES projects as national budget is not allocated to this type of measures. Administration of the Structural Funds and criteria of their use are complicated; national governments are lacking human capacities to

    More than 80% of energy used in households is dedicated to space heating. Large potential energy savings have been identified in the existing housing stock. Energy labelling of single-family houses is seen as an important instrument to provide new house owners with information on efficient energy saving investments that can be made on the house. This paper evaluates the effects of the Danish Energy Labelling Scheme on energy consumption in existing single-family houses with propensity score matching using actual consumption of energy and register data describing the houses and households. We do not find significant energy savings due to the Danish Energy Labelling Scheme. (Author)

    Multifamily housing project managers can reduce their energy costs from 30 to 60 percent by capitalizing on a variety of energy conservation opportunities (ECO's) identified in HUD research on the physical condition of public housing stock. This workbook prepares managers for this planning and for making individualized energy audits. It provides all the materials they need to proceed, including analysis sheets for calculating costs - benefit and payback periods for each of the 50 ECO's described. The ECO's listed all into four general categories: architectural improvements to the energy design of the building envelope; heating system ECO's to increase energy efficiency; secondary ECO's related to the domestic water supply, air conditioning systems, and central laundry equipment; and electric system ECO's reducing utility surcharges and increasing light bulb efficiency.

    Interventions to mitigate fuel poverty and particularly energy efficiency façade retrofitting (EEFR) have demonstrated positive impacts on health but the impacts of EEFR interventions on cold-related mortality have not been studied in depth. We evaluated the impact of EEFR interventions in Barcelona on the association between cold outdoor temperatures and mortality (from all natural causes and from neoplasms, circulatory system and respiratory system causes) from 1986 to 2012. A time-stratified case-crossover analysis was used. Relative risks (RR) for death related to extreme cold (lowest fifth percentile) in the no-intervention and intervention groups were obtained for temperature lag windows covering the day of the death and the previous 20 days (0-2, 3-5, 6-8, 9-11, 12-14, 15-17, 18-20). The statistical significance of the observed changes was evaluated using the RR for the cold temperature-intervention interaction. In men, interventions significantly increased the extreme cold-death association for the lag window 15-17 [interaction RR 2.23, 95% confidence interval (CI) 1.14-4.36]. The impacts were stronger for respiratory system causes and in men aged 75 or older. In women, on lag window 0-2, the extreme cold-death association was not significantly reduced when analysing all natural causes of death (interaction RR 0.46, 95% CI 0.21-1.01), but it was reduced significantly when analysing only deaths from neoplasms, circulatory system and respiratory system causes together. The impacts were stronger in women who died from circulatory system causes, in women with no education and in those aged 75 or older. EEFR interventions had differentiated effects on cold-related mortality in men and women. Differentiated effects were also observed by cause, educational level and age.

  12. Windows in Low Energy Houses. Size Matters

    Energy Technology Data Exchange (ETDEWEB)

    Persson, Mari-Louise

    2004-06-01

    A generally accepted way of building passive houses has been to have small windows facing north and a large glass facade to the south. This is to minimize losses on the north side while gaining as much solar heat as possible on the south. In spring 2001, twenty terraced houses were built outside Goeteborg partly in this way. The indoor temperature is kept at a comfortable level by passive methods, using solar gains and internal gains from household appliances and occupants. Heat losses are very low, since the building envelope is well insulated and since modern coated triple-glazed windows have been installed. The purpose of this work is to investigate how decreasing the window size facing south and increasing the window size facing north in low energy houses will influence the energy consumption and maximum power needed to keep the indoor temperature between 23 and 26 deg C. Different climates and orientations have been investigated and so have the influence of occupancy and window type. A dynamic building simulation tool, DEROB, has been used and the simulations indicate an extremely low energy demand for the houses. The results show that the size of the energy efficient windows does not have a major influence on the heating demand in winter, but is of relevant signification looking at the cooling need in summer. This indicates that instead of the traditional technique of building passive houses it is possible to enlarge the window area facing north and get better lighting conditions. To decrease the energy need for cooling, there is an optimal window size facing south that is smaller than the original size of the investigated buildings.

    There are various options for retrofitting Russian prefabricated concrete-slab buildings of the first period of industrial construction, so-called khrushchevki, with the object of bringing them up to European standards of thermal insulation technology. In the given case the basis of calculations was the German EnEV 2007 (Building Energy Conservation Ordinance). The analysis of sample building data opened up a large range of possibilities for increasing its energy efficiency. For instance, calculations ascertained that relatively inexpensive methods of enhancing a buildings thermal insulation can achieve a significant decrease in energy consumption for heating. In addition, this thesis analyzes possible variations of retrofitting and reconstruction using different types of materials and heating systems. The results clearly illustrate that residential houses e.g. type series 1-507 have a future as comfortable and functional housing space. In fact, and in contrast to common prejudices, their fate is far from hopeless. Even the climatic circumstances of a northern city such as St. Petersburg do not preclude the use of alternative energy sources such as solar energy. On the contrary, it is a conceivable method of support for heating systems. In summary, the investigations show that the retrofitting of prefabricated concrete-slab buildings of the first construction period is a sensible project, especially when taking into account the further development of fossil energy prices. In its most sophisticated form (the passive house), retrofitting will result in energy savings of up to 90 %.

    In the fall of 2010, a multiyear pilot energy efficiency retrofit project was undertaken by Greenbelt Homes, Inc, (GHI) a 1,566 home cooperative of circa 1930 and 1940 homes in Greenbelt, Maryland. GHI established this pilot project to serve as a basis for decision making for the rollout of a decade-long community-wide upgrade program that will incorporate energy efficiency improvements to the building envelope and mechanical equipment. With the community upgrade fully funded by the cooperative through their membership without outside subsidies, this project presents a unique opportunity to evaluate and prioritize the wide-range of benefits of high-performance retrofits based on member experience with and acceptance of the retrofit measures implemented during the pilot project. Addressing the complex interactions between benefits, trade-offs, construction methods, project management implications, realistic upfront costs, financing, and other considerations, serves as a case study for energy retrofit projects to include high-performance technologies based on the long-term value to the homeowner. The pilot project focused on identifying the added costs and energy savings benefits of improvements. Phase 1: baseline evaluation for a representative set of 28 homes sited in seven buildings; Phase 2: installation of the building envelope improvements and continued monitoring of the energy consumption for the heating season and energy simulations supporting recommendations for HVAC and water heating upgrades to be implemented in Phase 3.

    Energy efficiency is a central target for energy policy and a keystone to mitigate climate change and to achieve a sustainable development. Although great efforts have been carried out during the last four decades to investigate the issue, focusing into measuring energy efficiency, understanding its trends and impacts on energy consumption and to design effective energy efficiency policies, many energy efficiency-related concepts, some methodological problems for the construction of energy efficiency indicators (EEI) and even some of the energy efficiency potential gains are often ignored or misunderstood, causing no little confusion and controversy not only for laymen but even for specialists. This paper aims to revisit, analyse and discuss some efficiency fundamental topics that could improve understanding and critical judgement of efficiency stakeholders and that could help in avoiding unfounded judgements and misleading statements. Firstly, we address the problem of measuring energy efficiency both in qualitative and quantitative terms. Secondly, main methodological problems standing in the way of the construction of EEI are discussed, and a sequence of actions is proposed to tackle them in an ordered fashion. Finally, two key topics are discussed in detail: the links between energy efficiency and energy savings, and the border between energy efficiency improvement and renewable sources promotion.

    Full Text Available This paper presents the findings from an undergraduate research project concerning the energy efficiency, consumption, and generation of a 1000 ft2 (92.9 m2 solar house. The results were compared to a home of similar size and layout, built using traditional construction methods. The solar house was modeled after the Chameleon House: Missouri University of Science and Technology’s 2013 entry in the U.S. Department of Energy Solar Decathlon. The efficiency of the design was analyzed using Energy-10 Version 1.8 software. For this comparison, a fictional American couple was created and a breakdown of their energy-use habits was recorded to accurately depict the magnitude of energy consumption. A 71% energy savings was forecasted using the Energy-10 software through the incorporation of various energy-conserving strategies in the home’s design. In addition, if a 9.1 kW photovoltaic array is also installed on a home of this size, it is possible to fully offset the energy consumption of the home. The forecasted energy usage and production detailed in this report shall be used for analyzing the integrity of the design of the Chameleon House as well as future solar houses constructed by the Missouri S&T Solar House Team.

    Energy and environmental policies are reconsidering energy efficiency. In a perfect market, rational and well informed consumers reach economic efficiency which, at the given prices of energy and capital, corresponds to physical efficiency. In the real world, market failures and cognitive frictions distort the consumers from perfectly rational and informed choices. Green incentive schemes aim at balancing market failures and directing consumers toward more efficient goods and services. The problem is to fine tune the incentive schemes [it

The main problems of implementing energy-saving measures were touched; the need for their analysis during the development of each construction project with a view to choosing the most effective complex from the energy, economic, ecological and social points of view was justified. It is noted that such an approach can become an important factor of saving energy in the sphere of housing construction and reducing the energy intensity of the entire Russian economy.

    This feasibility study of passive houses and low-energy houses has raised several questions concerning aspects of which more knowledge is needed. Many can be answered by existing knowledge, but there are still several that can only partly be answered, and some that cannot be answered at all. As there is a substantial demand for, and interest in, the construction of low-energy houses and passive houses, it is important that the remaining questions should be addressed so that the building sector can continue to develop. Examples of areas where further knowledge is needed include: moisture safe and energy-efficient building envelopes; demand-responsive ventilation, without risk of poor indoor environmental conditions; thermal comfort (summer and winter); airtight and durable detailing; design systems and working methods to ensure retention of good characteristics when converting or extending buildings; durability aspects of certain components and functions; the effects of occupants on energy use; how indoor environment conditions and functions will cope with climate change; quality assurance in order to ensure that the appropriate knowledge is applied, and that the work is carried out properly. Some important points to emphasise: The design and construction of low-energy houses and passive houses must be firmly based on the correct design principles and appropriate standards of workmanship, in order to ensure that the houses are energy-efficient, have good indoor environmental conditions and can be expected to have long lives. Proper understanding of the principles, coupled with constant quality awareness, are essential in all stages of the work from the developer, designer and construction personnel but also during operation-phase. Hitherto, low-energy houses and passive houses have been built in relatively small numbers, but the expectation is that interest in them will increase. This raises the question of how, if production is to be very much more than at present

    Collaboratives for energy efficiency have a long and successful history and are currently used, in some form, in more than half of the states. Historically, many state utility commissions have used some form of collaborative group process to resolve complex issues that emerge during a rate proceeding. Rather than debate the issues through the formality of a commission proceeding, disagreeing parties are sent to discuss issues in a less-formal setting and bring back resolutions to the commission. Energy efficiency collaboratives take this concept and apply it specifically to energy efficiency programs—often in anticipation of future issues as opposed to reacting to a present disagreement. Energy efficiency collaboratives can operate long term and can address the full suite of issues associated with designing, implementing, and improving energy efficiency programs. Collaboratives can be useful to gather stakeholder input on changing program budgets and program changes in response to performance or market shifts, as well as to provide continuity while regulators come and go, identify additional energy efficiency opportunities and innovations, assess the role of energy efficiency in new regulatory contexts, and draw on lessons learned and best practices from a diverse group. Details about specific collaboratives in the United States are in the appendix to this guide. Collectively, they demonstrate the value of collaborative stakeholder processes in producing successful energy efficiency programs.

    Existing buildings require over 40% of the world's total final energy consumption, and account for 24% of world CO2 emissions (IEA, 2006). Much of this consumption could be avoided through improved efficiency of building energy systems (IEA, 2006) using current, commercially-viable technology. In most cases, these technologies make economic sense on a life-cycle cost analysis (IEA, 2006b). Moreover, to the extent that they reduce dependence on risk-prone fossil energy sources, energy efficient technologies also address concerns of energy security.

A National Energy Efficiency Programme is being launched in the Eighth Plan that will take into account both macro level and policy and planning considerations as well as micro level responses for different category of users in the industry, agriculture, transport and domestic sectors. The need for such a National Energy Efficiency Programme after making an assessment of existing energy conservation activities in the country is discussed. The broad framework and contents of the National Energy Efficiency Programme have been outlined and the Eighth Plan targets for energy conservation and their break-up have been given. These targets, as per the Eighth Plan document are 5000 MW in electricity installed capacity and 6 million tonnes of petroleum products by the terminal year of the Eighth Plan. The issues that need to be examined for each sector for achieving the above targets for energy conservation in the Eighth Plan are discussed briefly. They are: (a) policy and planning, (b) implementation arrangements which include the institutional setup and selective legislation, (c) technological requirements, and (d) resource requirements which include human resources and financial resources.

    Outlined herein are a procedure developed to simulate performance of an energy-autonomous (independent) solar house referred to as HARBEMAN HOUSE (HH) built in 1996 in City of Sendai, comparison between the simulated and observed results, and characteristics of the solar house. The house is equipped with a solar collector and sky radiator, both installed on the roof, the former facing south to collect solar energy and generate hot water whereas the latter facing north to radiate heat and generate cool water. Both are connected to an underground heat-insulated tank having a capacity of 31m{sup 3}, which stores hot or cool water to keep their conditions for extended periods. The solar system operates in heat- or cool-storage mode. In the heat-storage mode, quantity of heat stored increases, although at a slow rate, as tank capacity increases. In the cool-storage mode, on the other hand, quantity of cool stored increases in proportion to tank capacity. This is because solar energy is collected throughout the year whereas cooling by radiation is concentrated in early spring. Loss rate of heat stored increases as tank capacity increases, and the opposite trend is observed with cool stored. 12 refs., 7 figs., 2 tabs.

    Transport is the sector with the highest final energy consumption and, without any significant policy changes, is forecast to remain so. In 2008, the IEA published 25 energy efficiency recommendations, among which four are for the transport sector. The recommendations focus on road transport and include policies on improving tyre energy efficiency, fuel economy standards for both light-duty vehicles and heavy-duty vehicles, and eco-driving. Implementation of the recommendations has been weaker in the transport sector than others. This paper updates the progress that has been made in implementing the transport energy efficiency recommendations in IEA countries since March 2009. Many countries have in the last year moved from 'planning to implement' to 'implementation underway', but none have fully implemented all transport energy efficiency recommendations. The IEA calls therefore for full and immediate implementation of the recommendations.

    In order to achieve national, European and international energy goals, energy efficiency strategies in the building sector have to be implemented. The passive house standard and low energy standards are already successfully established in single dwelling houses. These high performance standards are starting to penetrate into the sector of housing associations. A case study about an apartment building constructed by a housing association is presented here. It describes the monitoring concept and the results of the 1st year of monitoring. Depending on the definition of the zero energy building standard (extent of loads included in the balancing), the building could be classified as an energy plus building or as a building, which uses more energy, than is supplied by on-site generation. If the building's total energy use (including user specific loads) is defined as load, only 34.5% of these loads were provided by the net energy output of the PV system. If only the heating energy demand is defined as load, the PV system even yielded a surplus of 45.6% of the energy load. -- Highlights: ► Energy monitoring of an apartment building constructed by a housing association. ► Planned as a Passive House with a semi-central ventilation system with decentralized heat pump technology. ► Total end energy demand of the building was 43 kWh/(m² a). ► Total net energy generation by the PV system was 15 kWh/(m² a). ► Apartment no. 1: 52% of the energy demand were used for heating and ventilation.

    The Low Energy Panel will halve the consumption in buildings. The Panel has proposed a halving of consumption in the construction within 2040 and 20 percent reduction in the consumption in the industry within 2020. The Panel consider it as possible to gradually reduce consumption in buildings from the current level of 80 TWh with 10 TWh in 2020, 25 TWh in 2030 and 40 TWh in 2040. According the committee one such halving can be reached by significant efforts relating to energy efficiency, by greater rehabilitations, energy efficiency in consisting building stock and stricter requirements for new construction. For the industry field the Panel recommend a political goal to be set at least 20 percent reduction in specific energy consumption in the industry and primary industry beyond general technological development by the end of 2020. This is equivalent to approximately 17 TWh based on current level of activity. The Panel believes that a 5 percent reduction should be achieved by the end of 2012 by carrying out simple measures. The Low Energy Panel has since March 2009 considered possibilities to strengthen the authorities' work with energy efficiency in Norway. The wide complex panel adds up proposals for a comprehensive approach for increased energy efficiency in particular in the building- and industry field. The Panel has looked into the potential for energy efficiency, barriers for energy efficiency, assessment of strengths and weaknesses in the existing policy instruments and members of the Panel's recommendations. In addition the report contains a review of theoretical principles for effects of instruments together with an extensive background. One of the committee members have chosen to take special notes on the main recommendations in the report. (AG)

    In this address the author describes three dimensions of energy efficiency in order of increasing costs: conservation, resource and technology substitution, and changes in economic structure. He emphasizes the importance of economic rather than environmental rationales for energy efficiency improvements in developing countries. These countries do not place high priority on the problems of global climate change. Opportunities for new technologies may exist in resource transfer, new fuels and, possibly, small reactors. More research on economic and social impacts of technologies with greater sensitivity to user preferences is needed

    Data Center facilities, prevalent in many industries and institutions are essential to California's economy. Energy intensive data centers are crucial to California's industries, and many other institutions (such as universities) in the state, and they play an important role in the constantly evolving communications industry. To better understand the impact of the energy requirements and energy efficiency improvement potential in these facilities, the California Energy Commission's PIER Industrial Program initiated this project with two primary focus areas: First, to characterize current data center electricity use; and secondly, to develop a research ''roadmap'' defining and prioritizing possible future public interest research and deployment efforts that would improve energy efficiency. Although there are many opinions concerning the energy intensity of data centers and the aggregate effect on California's electrical power systems, there is very little publicly available information. Through this project, actual energy consumption at its end use was measured in a number of data centers. This benchmark data was documented in case study reports, along with site-specific energy efficiency recommendations. Additionally, other data center energy benchmarks were obtained through synergistic projects, prior PG&E studies, and industry contacts. In total, energy benchmarks for sixteen data centers were obtained. For this project, a broad definition of ''data center'' was adopted which included internet hosting, corporate, institutional, governmental, educational and other miscellaneous data centers. Typically these facilities require specialized infrastructure to provide high quality power and cooling for IT equipment. All of these data center types were considered in the development of an estimate of the total power consumption in California. Finally, a research ''roadmap'' was developed

    To reduce fossil fuel consumption and CO2 emission, this article introduces an actually constructed natural energy autonomous house. It has a solar collector on the south roof for hot water supply and a sky radiator on the north roof for cooling water supply. The sky radiator uses radiation cooling phenomena into the space by electromagnetic wave through the window of atmosphere. This house also has an insulated tank with a capacity of 31 m{sup 3} in its underground. In the long-term heat storage mode, the heat is collected through the solar radiation during the period from summer to spring and is stored in the underground water tank, to use it for heating and hot water supply in winter. The heat can be recovered from the garbage waste incinerator. A gas fired auxiliary boiler is used for the shortage. In the long-term heat regeneration mode, the heat is regenerated through the sky radiator during the period from spring to summer and is stored in the underground water tank, to use it for cooling in summer. For the shortage, the water is cooled using a heat pump operated by the midnight power. The insulating performance is improved by using the pair glass in windows and the glass wool in the walls. Rain water is collected in a tank with a capacity of 2 m{sup 3}, to use it for toilet water. Annual energy and water saving is equivalent to 600,000 yen. 10 refs., 10 figs., 2 tabs.

    In the last years much attention has been given to the polluting gas discharges, in special of those that favor the green house effect (GHE), due to the negative sequels that its concentration causes to the atmosphere, particularly as the cause of the increase in the overall temperature of the planet, which has been denominated world-wide climatic change. There are many activities that allow to lessen or to elude the GHE gas emissions, and with the main ones the so-called projects of Energy Efficiency and Renewable Energy (EE/RE) have been structured. In order to carry out a project within the frame of the MDL, it is necessary to evaluate with quality, precision and transparency, the amount of emissions of GHE gases that are reduced or suppressed thanks to their application. For that reason, in our country we tried different methodologies directed to estimate the CO{sub 2} emissions that are attenuated or eliminated by means of the application of EE/RE projects. [Spanish] En los ultimos anos se ha puesto mucha atencion a las emisiones de gases contaminantes, en especial de los que favorecen el efecto invernadero (GEI), debido a las secuelas negativas que su concentracion ocasiona a la atmosfera, particularmente como causante del aumento en la temperatura general del planeta, en lo que se ha denominado cambio climatico mundial. Existen muchas actividades que permiten aminorar o eludir las emisiones de GEI, y con las principales se han estructurado los llamados proyectos de eficiencia energetica y energia renovables (EE/ER). Para llevar a cabo un proyecto dentro del marco del MDL, es necesario evaluar con calidad, precision y transparencia, la cantidad de emisiones de GEI que se reducen o suprimen gracias a su aplicacion. Por ello, en nuestro pais ensayamos diferentes metodologias encaminadas a estimar las emisiones de CO{sub 2} que se atenuan o eliminan mediante la aplicacion de proyectos de EE/ER.

  2. Does energy labelling on residential housing cause energy savings?

    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

    This report provides a technical description of the methodology and the results of a two year effort to collect field data on the performance of passive solar and energy conserving houses in California. Sixty-three passive solar houses were visited and several hours were spent with the homeowner obtaining building details, management procedures, architectural plans, photographs, and at least a year of billing data. With this information thermal performance parameters were calculated for each of the houses. Eleven of the above sixty-three Class C sites (nine passive solar and two energy conserving houses) were instrumented and monitored using the SERI Class B methodology as a guideline. Continuous data were collected for one year using up to 18 different sensors to measure temperatures, electric power, insolation, and the status of fans, gas burners, and moveable insulation. In addition careful one time measurements were made to determine the loss coefficient, infiltration rate, and furnace efficiency. Analysis of this data giving comfort conditions maintained and energy uses for a complete heating and cooling season for each of the houses is presented.

  5. Energy efficiency fallacies revisited

    Brookes, Leonard

    2000-01-01

    A number of governments including that of the UK subscribe to the belief that a national program devoted to raising energy efficiency throughout the economy provides a costless - indeed profitable - route to meeting international environmental obligations. This is a seductive policy. It constitutes the proverbial free lunch - not only avoiding politically unpopular measures like outlawing, taxing or rationing offending fuels or expanding non-carboniferous sources of energy like nuclear power but doing so with economic benefit. The author of this contribution came to doubt the validity of this solution when it was offered as a way of mitigating the effect of the OPEC price hikes of the 1970s, maintaining that economically justified improvement in energy efficiency led to higher levels of energy consumption at the economy-wide level than in the absence of any efficiency response. More fundamentally, he argues that there is no case for preferentially singling out energy, from among all the resources available to us, for efficiency maximisation. The least damaging policy is to determine targets, enact the restrictive measures needed to curb consumption, and then leave it to consumers - intermediate and final - to reallocate all the resources available to them to best effect subject to the new enacted constraints and any others they might be experiencing. There is no reason to suppose that it is right for all the economic adjustment following a new resource constraint to take the form of improvements in the productivity of that resource alone. As many others have argued, any action to impose resource constraint entails an inevitable economic cost in the shape of a reduction in production and consumption possibilities: there would be no free lunch. In the last few years debate about the validity of these contentions has blossomed, especially under the influence of writers on the western side of the Atlantic. In this contribution the author outlines the original arguments

    Integral energy concepts for housing estates require an early cooperation between architects, planners, and specialist engineers on the basis of a holistic planning approach. This is how future-oriented, sustainable concepts evolve which do justice to the multifarious requirements on the integral energy system of a housing estate. The present paper elucidates different approaches to optimising the energy efficiency of buildings such as the implementation of low-energy house concepts, building site and architectural planning, and detailed planning of heat insulation concepts, ventilation and air tightness concepts, and adapted heating systems. The solarisation of development plans has an influence on the arrangement of buildings, which are now planned to give the greatest possible passive and active solar energy gains. The authors also describe solar-assisted district heating systems for housing estates.

    Hydrogen technology and passive house represent two concepts with a remarkable role for the efficiency and decarbonisation of energy systems in the residential buildings area. Through design and functionality, the passive house can make maximum use of all available energy resources. One of the solutions to supply energy of these types of buildings is the fuel cell, using this technology integrated into a system for generating electricity from renewable primary sources, which take the function of backup power (energy reserve) to cover peak load and meteorological intermittents. In this paper is presented the results of the case study that provide an analysis of the energy, environmental and financial performances regarding energy supply of passive house by power generation systems with fuel cell fed with electrolytic hydrogen produced by harnessing renewable energy sources available. Hybrid systems have been configured and operate in various conditions of use for five differentiated locations according to the main areas of solar irradiation from the Romanian map. Global performance of hybrid systems is directly influenced by the availability of renewable primary energy sources - particular geo-climatic characteristics of the building emplacement.

    Highlights: • Active and passive solar house technology is integrated in the solar house. • Solar thermal system and solar photoelectric system are measured and analyzed. • Energy balance and energy consumption are analyzed with valuable experimental data. • “Zero energy consumption” is truly achieved with the solar supply rate of 1.19 in winter. - Abstract: An integrated solar house with numerous advanced envelops is designed and constructed to investigate the comprehensive utilization of solar energy, energy efficiency and energy balance, which combines active solar house technology with passive solar house technology including solar photovoltaic system, solar water heating system, direct-gain door and windows. Solar radiation intensity, performance of the photovoltaic system, water temperature, and indoor and outdoor temperature are measured, results of the experiments indicate that solar glass window on the south wall can maintain the average indoor temperature at 21.4 °C in the case of average outdoor temperature at 11.2 °C without any external heat supply. The output current of the solar photovoltaic system shows the same trend as solar radiation intensity. When the intensity is 619.7 W/m 2 , the instantaneous generation power could reach a value of 781.9 W, cumulative capacity throughout the day achieves 4.56 kW h and photovoltaic conversion efficiency 9.8%. When the average intensity throughout a day is 358 W/m 2 , the solar water heating system could help to raise the temperature of 450 L water by 30 °C with its heat collecting efficiency being 37.4%. Through the analysis of the overall energy system in the solar house, it can be derived that this solar house could achieve “zero energy consumption” in winter with the solar supply rate at 1.19.

    2018-03-01

    The article presents the results of a complex experimental-analytical research of residential development energy parameters - survey of construction sites and determination of calculated energy parameters (resistance to heat transfer) considering their technical condition. The authors suggest a methodology for assessing residential development energy parameters on the basis of construction project's structural analysis with the use of advanced intelligent collection systems, processing (self-organizing maps - SOM) and data visualization (geo-informational systems - GIS). SOM clustering permitted to divide the housing stock (on the example of Arkhangelsk city) into groups with similar technical-operational and energy parameters. It is also possible to measure energy parameters of construction project of each cluster by comparing them with reference (normative) measures and also with each other. The authors propose mechanisms for increasing the area's energy stability level by implementing a set of reproduction activities for residential development of various groups. The analysis showed that modern multilevel and high-rise construction buildings have the least heat losses. At present, however, ow-rise wood buildings is the dominant styles of buildings of Arkhangelsk city. Data visualisation on the created heat map showed that such housing stock covers the largest urban area. The development strategies for depressed areas is in a high-rise building, which show the economic, social and environmental benefits of upward growth of the city. An urban regeneration programme for severely rundown urban housing estates is in a high-rise construction building, which show the economic, social and environmental benefits of upward growth of the city.

    A discussion was given on an `energy autonomous house` which utilizes more effectively photovoltaic power generation, solar heat and light in designing a wooden house to be built by using the conventional construction method. According to the plan, photovoltaic power generation modules and heat collectors are installed superimposed on a roof facing south. Heat-collected air is sent below the floor and the heat is stored in the concrete in winter, utilized as the floor heating type room heater. The hot air is used for hot water supply in other seasons. The building is of two stories with a total area of 118 m {sup 2}, and the photovoltaic generation capacity is 3.48 kW. The photovoltaic generation amount was calculated from insolation forecasted by the AMEDAS system, and energy balance of this house was estimated. The result therefrom may be summarized as follows: total energy supplied reached 11.6 Gcal, signifying that about 10.8% of the energy irradiated onto the building is utilized; ratio of the photovoltaic and solar heat utilization is 27% versus 73%; and energy consumption in this house was estimated and calculated from actual results, airtightness and adiabatic performance of old houses, whereas the energy autonomous rate has reached 92.8%. 5 refs., 2 figs., 8 tabs.

    2015-01-01

    In Brazil the housing deficit is around 5.5 million houses. To address this need, the government created a programme called “My house, My life”. The main subsidies of the programme are for families earning up to three times the minimum wage. In order to formulate strategies for more energy efficiency buildings, it is necessary to understand the thermal and energy performance of what is being built. This article defines representative projects for typologies being built in the Brazilian social housing sector through the analysis of 108 projects considering two groups of income levels and investigates the thermal and energy performance of the representative projects in relation to the Regulation for Energy Efficiency Labelling of Residential Buildings in Brazil for two bioclimatic zones. Five representative building models were defined. Considering the most common features found on the sample, the study suggests the importance of addresing energy efficiency measures on the sector since current building techniques for social housing shows a tendency towards a low performance in relation to the thermal and energy performance criteria of the Energy Labelling especially for lower income projects. This provides a basis for future policy and allows for more in depth studies within the sector. - Highlights: • Characterisation of representative typologies built for social housing in Brazil. • More recurrent building physics characteristics considered. • Energy efficiency and thermal performance of Brazilian social housing analysed. • Regulation for Energy Efficiency Labelling of Residential Buildings in Brazil used for analysis.

    Full Text Available Objectives. The aim of the research is to develop a thin-film semiconductor thermoelectric heat pump of cylindrical shape for the desalination of sea water.Methods. To improve the efficiency of the desalination device, a  special thin-film semiconductor thermoelectric heat pump of  cylindrical shape is developed. The construction of the thin-film  semiconductor thermoelectric heat pump allows the flow rates of  incoming sea water and outflowing fresh water and brine to be  equalised by changing the geometric dimensions of the desalinator.  The cross-sectional area of the pipeline for incoming sea water is equal to the total area of outflowing fresh water and brine.Results. The use of thin-film semiconductor p- and n-type branches  in a thermo-module reduces their electrical resistance virtually to  zero and completely eliminates Joule's parasitic heat release. The  Peltier thermoelectric effect on heating and cooling is completely  preserved, bringing the efficiency of the heat pump to almost 100%, improving the energy-saving characteristics of the  desalinator as a whole. To further increase the efficiency of the  proposed desalinator, thermoelectric modules with radiation can be  used as thermoelectric devices.Conclusion. As a consequence of the creation of conditions of high rarefaction under which water will be converted to steam, which, at  20° C, is cold (as is the condensed distilled water, energy costs can  be reduced. In this case, the energy for heating and cooling is not  wasted; moreover, sterilisation is also achieved using the ultraviolet  radiation used in the thermoelectric devices, which, on the one hand, generate electromagnetic ultraviolet radiation, and, on the other, cooling. Such devices operate in optimal mode without heat  release. The desalination device can be used to produce fresh water and concentrated solutions from any aqueous solutions, including wastewater from industrial

  18. The building process of single-family houses and the embeddedness (or disembeddedness) of energy

    International Nuclear Information System (INIS)

    People building their own houses have, at least theoretically, substantial autonomy when choosing, for example, a heating system and windows. In this article, focus is on the process of building new single-family houses and how energy efficiency and energy-efficient technology are incorporated into the building process. The conclusions emphasize energy as only one factor in housing purchase decisions. It is a big challenge to make low-energy building important to consumers. Consumer preferences for new products are unlikely to fully develop unless individuals have the opportunity to interact with them. It is difficult for consumers to know what to ask for if they lack experience of energy-efficient technologies. In the studied cases, the building codes and established standards became extremely decisive for how energy issues were included in the process. There is a need to change the design of incentives so as to make the least energy-efficient choice the most expensive. The most energy-efficient solution should be standard, and if the buyer wants to depart from that standard and build using less energy-efficient construction, then that should cost more. -- Highlights: •Actors do not see energy efficiency as a critical problem. •Factors other than costs and price were important in the decision making. •Energy issues just one factor in housing purchase decisions. •The consumers don′t know what to ask for. •Building norms should require the most energy efficient solution

    In this report we describe a method to compare the energy performance in use with the energy performance calculation of newly build houses. We put the average real energy use of a project in the calculation method of the energy performance of new houses. In that way we could compare the energy performance of the building permit with the real performance in practice. Because the calculation method normalizes the energy use of a house by its user surface and surface of building shell, the energy performance of different projects could be compared also when the projects exist of different dwelling types. Also the energy performance of different energy concepts could be compared such as all-electric houses with a heat pump or houses with a gas fired condensing boiler [Dutch] Agentschap NL is betrokken bij veel nieuwbouwprojecten. Een grote vraag is altijd of in de praktijk ook de prestaties worden gehaald die van te voren werden verwacht. Agentschap NL heeft voorgesteld hiervoor een maat te ontwikkelen, namelijk de Reele EPC. ECN heeft deze methodiek uitgewerkt om van woningbouwprojecten de energieprestatie in de praktijk te vergelijken met de geplande EPC. Het idee is dat de energieprestatie in de praktijk wordt uitgedrukt in een reële EPC (de R-EPC)

  1. Passive energy standard in building as a perspective of sustainable development - first passive houses in Croatia

    International Nuclear Information System (INIS)

    Miscevic, Lj.

    2005-01-01

    The paper presents the projects and implementation of the first passive family houses in Croatia. The Croatian Solar House (CSH) is a national technological-development project by a group of authors, which is based on passive house standard as an energy-terms point of departure. The House EV1 is a wood-made passive house under construction, while the House M4 is the first passive house in Croatia made in poro-concrete and reinforced concrete made ceiling slabs. Both houses comply with the heating energy consumption requirements under the passive house definition, i.e., the annual consumption does not exceed 15 kWh/m2. These houses are also referred to as 'houses without heating', 'houses with thermal comfort without heating' or 'one-liter houses' because their consumption is equivalent to one liter of fuel oil by one square meter a year. Assuming the high-value thermal protection, passive house is equipped with an installation system which houses a heat pump and ventilation system for continuous introduction of fresh air indoors. The use of renewable energy sources enabled the accomplishment by far the biggest energy savings in the construction industry, ensuring optimal conditions for healthy living without harmful gas emissions. Since 1990 there is an exponential growth of constructed passive houses in Europe. Germany is leading this trend with total of 150,000 free-standing houses, house raw units or residential units in small multi-apartment buildings. The research project-program of the European Union: Cost Efficiency Passive Houses as European Union Standard (CEPHEUS) has confirmed, by scientific monitoring during several years, the energy- and cost-efficiency of such architecture and construction model in more than 250 units in Germany, France, Austria and Switzerland. Therefore the passive house is proposed as a standard for residential architecture and construction, but also for general construction of all functional types of non-residential architecture

    Most energy analysts view low-energy houses as good things, yet differ in their expectations of what exactly a low energy house is. There are two intertwining threads to this report. The first is an evaluation of 50 buildings that have been claimed to be low-energy residences, for which monitored energy performance data have been collected. These data represent the preliminary effort in the ongoing update of the Buildings Energy-Use Compilation and Analysis (BECA) data base for new residences. The second thread concerns the definition of a low-energy house. After the elements of a definition are presented, their implications for actors involved in providing housing are identified. Several more tractable definitions are applied to the houses in this compilation. The outcomes illustrate ways in which different interests are served by various definitions. Different definitions can yield very different energy rankings. No single definition of a low-energy house is universally applicable.

    ??National programs such as Home Performance with ENERGY STAR(R) and numerous other utility air sealing programs have brought awareness to homeowners of the benefits of energy efficiency retrofits. Yet, these programs tend to focus on the low-hanging fruit: air-sealing the thermal envelope and ductwork where accessible, switch to efficient lighting, and low-flow fixtures. At the other end of the spectrum, deep-energy retrofit programs are also being encouraged by various utilities across the country. While deep energy retrofits typically seek 50% energy savings, they are often quite costly and most applicable to gut-rehab projects. A significant potential for lowering energy usage in existing homes lies between the low hanging fruit and deep energy retrofit approaches - retrofits that save approximately 30% in energy over the existing conditions. A key is to be non-intrusive with the efficiency measures so the retrofit projects can be accomplished in occupied homes. This cold climate retrofit project involved the design and optimization of a home in Connecticut that sought to improve energy savings by at least 30% (excluding solar PV) over the existing home's performance. This report documents the successful implementation of a cost-effective solution package that achieved performance greater than 30% over the pre-retrofit - what worked, what did not, and what improvements could be made. Confirmation of successfully achieving 30% source energy savings over the pre-existing conditions was confirmed through energy modeling and comparison of the utility bills pre- and post- retrofit.

    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.

    This paper described energy and audit and building simulations conducted on an archetype sustainable house located in Woodbridge, Ontario. The house formed part of a project to construct low energy, sustainable house designs for mass production. The 2 houses formed a duplex. House A was designed using current best design practices, while house B was equipped with advanced and innovative technologies not commonly used in residential constructions. Natural Resources Canada's (NRCan) HOT2000 residential building simulation program was used to evaluate the performance of both houses in the duplex. The simulation program demonstrated that house B performed more efficiently than house A. However, neither houses met their designed values. Significantly larger space heating and cooling loads were identified. The program showed that additional weather-stripping around doors, and caulking around windows will help to reduce the amount of draft in the houses. Assessments are also needed to measure heat losses from the common wall in the basement. It was concluded that the energy performance of the house can be optimized by using the appropriate sealing techniques throughout the building envelope. 2 refs., 1 tab.

    Energy technology and energy economy in the fields of generation, distribution and application as well comprehensive environmental protection have been traditional focuses of the science and research of the University of Zittau/Goerlitz and it predecessor institutions since 1969. In the 1995 the 'low energy house' was completed at site Zittau. This completion proved to be an important milestone for the considerable profile extension of the University by using the capacities of that time. The project had an auspicious start. On the one hand the University wanted to focus more on environmentally friendly energy application, on the other hand the interest of new students in the field of environmental protection had increased considerably. The profile extension of the university was supported equally by the university management and the Ministry for Science and Art of Saxony. The idea came up in 1989, the first model was designed in 1990, in 1991 the request for construction was already approved of, from nowadays' perspective very short time lines and a great decisiveness.

    Highlights: • The life cycle energy demand of a passive house (PH) is measured over 100 years. • Embodied, operational and user transport energy demand are considered. • Embodied energy represents the highest energy consumption in all variations. • A PH might not save energy compared to a standard house. • A poorly insulated city apartment can use less energy than a best case suburban PH. - Abstract: Certifications such as the Passive House aim to reduce the final space heating energy demand of residential buildings. The latter are responsible for a significant share of final energy consumption in Europe of which nearly 70% is associated with space conditioning, notably heating. The improvement of the energy efficiency of residential buildings, in terms of space heating, can therefore reduce their total energy demand. However, most certifications totally overlook other energy requirements associated with residential buildings. Studies on passive houses do not take into consideration the embodied energy required to manufacture the building materials, especially the large amount of insulation required to achieve high operational efficiencies. At an urban scale, most passive houses are single family detached houses located in low density suburbs with a high car usage, resulting in considerable transport related energy demand. This paper analyses the total life cycle energy demand of a typical Belgian passive house, comprising embodied, operational and transport energy. It relies on a comprehensive technique developed by Stephan et al. [1] and conducts a parametric analysis as well as a comparison to alternative building types. Results show that current building energy efficiency certifications might not ensure a lower energy demand and can, paradoxically result in an increased energy consumption because of their limited scope. More comprehensive system boundaries should be used to make sure that net energy savings do occur. The embodied energy of passive

    Efficiency is one of the most frequently used terms in thermodynamics, and it indicates how well an energy conversion or process is accomplished. Efficiency is also one of the most frequently misused terms in thermodynamics and is often a source of misunderstanding. This is because efficiency is often used without being properly defined first. This book intends to provide a comprehensive evaluation of various efficiencies used for energy transfer and conversion systems including steady-flow energy devices (turbines, compressors, pumps, nozzles, heat exchangers, etc.), various power plants, cogeneration plants, and refrigeration systems. The book will cover first-law (energy based) and second-law (exergy based) efficiencies and provide a comprehensive understanding of their implications. It will help minimize the widespread misuse of efficiencies among students and researchers in energy field by using an intuitive and unified approach for defining efficiencies.

    Full Text Available Temporary housing plays an important role in providing secure, hygienic, private, and comfortable shelter in the aftermath of disaster (such as flood, fire, earthquake, etc.. Additionally, temporary housing can also be used as a sustainable form of on-site residences for construction workers. While most of the building components used in temporary housing can be manufactured in a plant, prefabrication technology improves the production efficiency of temporary housing; furthermore, integrated renewable energy systems, for example, solar photovoltaic (PV system, offer benefits for temporary housing operations. In order to assess the environmental impacts of prefabricated temporary housing equipped with renewable energy systems, this study first divides the life cycle of temporary housing into six stages, and then establishes a life cycle assessment (LCA model for each stage. Furthermore, with the aim of reducing the environmental impacts, life cycle carbon reduction measures are proposed for each stage of temporary housing. The proposed methodology is demonstrated using a case study in China. Based on the proposed carbon reduction measures, the LCA of a prefabricated temporary housing case study building equipped with renewable energy systems indicates a carbon emissions intensity of 35.7 kg/m2·per year, as well as a reduction in material embodied emissions of 18%, assembly emissions of 17.5%, and operational emissions of 91.5%. This research proposes a carbon reduction-driven LCA of temporary housing and contributes to promoting sustainable development of prefabricated temporary housing equipped with renewable energy systems.

    The need for energy retrofitting of the Danish single-family houses is massive, especially for the high proportion of single-family houses built in the 1960s and 1970s. But even though the potential benefits are many, only few families embark on a major energy retrofit. There may be many reasons...... for this. An obvious one may be limited knowledge of non-energy benefits, e.g. in relation to the indoor climate. The objective of this study was to explain this limited effort to save energy by identifying barriers and incentives among house owners in relation to energy retrofitting of one’s own house....... Moreover, it was investigated among house owners, who had carried out energy retrofitting, whether a number of factors, including the perceived indoor climate, became better or worse after retrofitting. A questionnaire survey was carried out among 1,990 house owners in a municipality north of Copenhagen...

    In August 2007 the German government agreed on the Integrated Energy and Climate Package (IECP) at Meseberg. This IECP-Macro study analyses the macroeconomic impacts of the IECP in Germany. The focus of analysis in IECP-Macro was on macroeconomic indicators, in particular on gross domestic product (GDP), consumption, investment and employment. This study links a bottom-up analysis of single policy measures with a macroeconomic analysis. The bottom-up impacts are fed into the ASTRA model, in which they trigger the macroeconomic impacts, e.g. a change of final demand in terms of investment or consumption. In total five scenarios have been analysed and have been compared with a reference scenario of the ASTRA model that has been aligned with the business-as-usual scenario of the project ''Politics Scenarios IV''. The basic conclusion of the analysis is that the economic stimulus of increased investment in climate policy stimulates economic growth in the short- and medium-term. Energy savings have the greatest effect to safeguard or even increase employment in the long run. (orig.)

    The U.S.S.R. is the largest energy producer and the second largest energy consumer in the world. Its share of global energy use reached above 17% in 1988. The soviet energy system is characterized by low efficiency and high per capita energy consumption, although there are some reasons justifying the greater U.S.S.R. energy use per unit of product output than in other industrialized countries. The present energy-savings potential is approximately equal to one-half of the domestic energy consumption. Improvements in energy efficiency at all levels of the national economy are now considered to be the primary goal of national energy policy for the next couple of decades. Being endowed with abundant natural gas resources, the U.S.S.R. will count on this energy source in the future to improve its energy efficiency, reduce expenses and cope with air pollution. After 2005-2010, stabilized primary energy consumption may be reached or there may even be a decline of total energy use. The U.S.S.R. could reduce CO 2 emissions by 20% by 2030 but with substantial negative impacts on GNP growth. Required improvements in the Soviet energy system depend on changes in energy management, including reduction of the role of centralized planning, decentralization and privatization of energy-producing facilities, energy-price reforms, reshaping of investment patterns, reduction in military expenditures, etc. (author)

    The paper challenges the view that improving the efficiency of energy use will lead to a reduction in national energy consumption, and hence is an effective policy for reducing CO{sub 2} emissions. It argues that improving energy efficiency lowers the implicit price of energy and hence makes its use more affordable, thus leading to greater use. The paper presents the views of economists, as well as green critics of 'efficiency' and the 'dematerialization' thesis. It argues that a more effective CO{sub 2} policy is to concentrate on shifting to non-fossil fuel, like renewables, subsidized through a carbon tax. Ultimately what is needed, to limit energy consumption is energy conservation not energy efficiency. 44 refs.

    The project has aimed to develop methods and examples related to the design of extensive energy renovations (low energy class 1) in order to stimulate energy conservation and increased use of renewable energy in existing buildings. The present report deals with potential opportunities and proposals for energy renovation of a typical old brick house built in the period 1910-40. Typically, these houses have little insulation, and therefore there is good reason to explore how this type of houses can be upgraded to BR08 (building code 2008), low energy class 2 or 1. (ln)

    options considered to date are not ideal. One approach is to insulate between the trusses at the roof plane. The construction process is time consuming and costs more than conventional attic construction. Moreover, the problems of air infiltration and thermal bridges across the insulation remain. Another approach is to use structurally insulated panels (SIPs), but conventional SIPs are unlikely to be the ultimate solution because an additional underlying support structure is required except for short spans. In addition, wood spline and metal locking joints can result in thermal bridges and gaps in the foam. This study undertook a more innovative approach to roof construction. The goal was to design and evaluate a modular energy efficient panelized roof system with the following attributes: (1) a conditioned and clear attic space for HVAC equipment and additional finished area in the attic; (2) manufactured panels that provide structure, insulation, and accommodate a variety of roofing materials; (3) panels that require support only at the ends; (4) optimal energy performance by minimizing thermal bridging and air infiltration; (5) minimal risk of moisture problems; (6) minimum 50-year life; (7) applicable to a range of house styles, climates and conditions; (8) easy erection in the field; (9) the option to incorporate factory-installed solar systems into the panel; and (10) lowest possible cost. A nationwide market study shows there is a defined market opportunity for such a panelized roof system with production and semi-custom builders in the United States. Senior personnel at top builders expressed interest in the performance attributes and indicate long-term opportunity exists if the system can deliver a clear value proposition. Specifically, builders are interested in (1) reducing construction cycle time (cost) and (2) offering increased energy efficiency to the homebuyer. Additional living space under the roof panels is another low-cost asset identified as part of

    A lot of today's world vices can be eliminated if certain targeted modules and adapted curricula are introduced in the schooling system. One of these vices is energy squandering with all its negative consequences for the planet (e.g. depletion of finite energy sources and the subsequent climate change). This paper describes the results of an energy-thrift information and education project taking place in different levels of education in Crete-Greece, which records 321 students' and their parents' routine energy-related behavior and proves that this behavior changes to a more energy efficient one, after the dissemination of relevant information and the participation into the energy education projects. Namely, response percentages indicating the energy-efficient behavior increased after project participation while the ones indicating an energy-squandering behavior decreased. The Wilcoxon signed rank test was statistically significant in all energy behavior questions related to students and to most questions related to parents

  16. Energy sustainability: consumption, efficiency, and ...

    Science.gov (United States)

    One of the critical challenges in achieving sustainability is finding a way to meet the energy consumption needs of a growing population in the face of increasing economic prosperity and finite resources. According to ecological footprint computations, the global resource consumption began exceeding planetary supply in 1977 and by 2030, global energy demand, population, and gross domestic product are projected to greatly increase over 1977 levels. With the aim of finding sustainable energy solutions, we present a simple yet rigorous procedure for assessing and counterbalancing the relationship between energy demand, environmental impact, population, GDP, and energy efficiency. Our analyses indicated that infeasible increases in energy efficiency (over 100 %) would be required by 2030 to return to 1977 environmental impact levels and annual reductions (2 and 3 %) in energy demand resulted in physical, yet impractical requirements; hence, a combination of policy and technology approaches is needed to tackle this critical challenge. This work emphasizes the difficulty in moving toward energy sustainability and helps to frame possible solutions useful for policy and management. Based on projected energy consumption, environmental impact, human population, gross domestic product (GDP), and energy efficiency, for this study, we explore the increase in energy-use efficiency and the decrease in energy use intensity required to achieve sustainable environmental impact le

    The Chinese government has set an ambitious target: reducing China's energy intensity by 20%, or 4.36% each year between 2006 and 2010 on the 2005 level. Real data showed that China missed its target in 2006, having reduced its energy intensity only by 1.3%. The objective of this study is to evaluate the feasibility and potential of the Chinese to achieve the target. This paper presents issues of macro-economy, population migration, energy savings, and energy efficiency policy measures to achieve the target. A top-down approach was used to analyse the relationship between the Chinese economic development and energy demand cycles and to identify the potentials of energy savings in sub-sectors of the Chinese economy. A number of factors that contribute to China's energy intensity are identified in a number of energy-intensive sectors. This paper concludes that China needs to develop its economy at its potential GDP growth rate; strengthen energy efficiency auditing, monitoring and verification; change its national economy from a heavy-industry-dominated mode to a light industry or a commerce-dominated mode; phase out inefficient equipment in industrial sectors; develop mass and fast railway transportation; and promote energy-efficient technologies at the end use. This paper transfers key messages to policy makers for designing their policy to achieve China's energy efficiency target

    This final report for the Swiss Federal Office of Energy (SFOE) takes a look at work done concerning low energy consumption housing in southern Switzerland. Thanks to large windows in the south-east facade and a well insulated building envelope, the passive solar gains are quoted as providing significant contributions to heating. The remaining heating requirements are covered by a closed fireplace and an electric radiator. Heat is distributed by free convection inside the house, A double-flux ventilation system with heat recovery ensures air renewal (3 volumes per day). Each house has a solar hot water system with electric auxiliary energy supply. Space heating requirements are discussed and compared with the standard values as defined in Swiss energy standards and the conventional auxiliary space heating energy required for the houses is noted.

    A significant amount of heat energy both for heating and process purposes is generated in Cracow, Poland in small-and medium size local boiler houses. The operating procedure of these boiler houses is most often economically and ecologically ineffective because of the bad condition of boilers and lack of funds to install automation, control and measurement equipment. Within the Polish-American Program of Elimination of Low Emission Sources financed by the US Department of Energy, the ENERGOEKSPERT Co., Ltd. investigated chosen boiler houses in Cracow, commissioned by the Cracow Development Office. The results of these investigations were subject of engineering analysis carried out at the Institute of Industrial Equipment and Power Engineering, Technical University, Cracow. The analysis proved that the low-cost improvement of economic efficiency and reduction of air pollutant emission is feasible for combustion of coal fuels.

    The city of Memphis Division of Housing and Community Development (HCD) receives grant funding each year from the U.S. Department of Housing and Urban Development (HUD) to provide local housing assistance to low-income residents. Through the years, HCD has found that many of the program recipients have had difficulty in managing their households, particularly in meeting monthly financial obligations. One of the major operating costs to low-income households is the utility bill. Furthermore, HCD's experience has revealed that many low-income residents are simply unaware of ways to reduce their utility bill. Most of the HCD funds are distributed to low-income persons as grants or no/low interest loans for the construction or rehabilitation of single-family dwellings. With these funds, HCD builds 80 to 100 new houses and renovates about 500 homes each year. Houses constructed or renovated by HCD must meet HUD's minimum energy efficiency standards. While these minimum standards are more than adequate to meet local building codes, they are not as aggressive as the energy efficiency standards being promoted by the national utility organizations and the home building industry. Memphis Light, Gas and Water (MLGW), a city-owned utility, has developed an award-winning program named Comfort Plus which promotes energy efficiency open-quote in new residential construction. Under Comfort Plus, MLGW models house plans on computer for a fee and recommends cost-effective alterations which improve the energy efficiency of the house. If the builder agrees to include these recommendations, MLGW will certify the house and guarantee a maximum annual heating/cooling bill for two years. While the Comfort Plus program has received recognition in the new construction market, it does not address the existing housing stock

    As France has just published a decree on the energy audit for large companies, and has thus been among the first countries to comply with an article of the European directive on energy efficiency, a set of articles discusses various aspects of these issues of energy efficiency and energy management. A first one presents this mandatory energy audit as a tool for a better energy efficiency, and illustrates the relationship between this commitment and the ISO 50001 standard for French large companies. A second article outlines the tools and standards of application of this energy audit in different legal texts. A third one comments the introduction of four new European arrangements on the labelling of products (indication of energy performance by retailers, objective of reduction of energy consumption, information displayed on site and on-line for various household appliances, current legislation). The next article comments the new German legislation on renewable energies which implements environmental requirements higher than European objectives, and tries to boost the carbon market. The presence of the ISO 50001 certification in the German law is also briefly addressed. Then, an article proposes an overview of a bill project, opinions of experts, and way to go for the new arrangement for energy saving certificates (CEE, certificat d'economie d'energie) launched by the French ministry of Ecology, and which aims at a 700 TWh saving. The content of each article of the bill project is presented and explained, and the relationship between certificate application and some standards is highlighted.

    Highlights: • Multi-period design methodology for heat recovery in local energy systems. • A systematic targeting for minimum utility requirements for urban utility systems. • Integration of industrial waste heat with local energy systems. • A case study providing insights for the heat recovery of discontinuous systems. - Abstract: This study aims to develop a novel design method for reducing the energy consumption and CO 2 emissions of local energy systems, simultaneously considering the recovery of industrial waste heat, and effectively dealing with the non-continuous nature of energy usage and heat recovery. A multi-period concept has been adopted for characterizing the change of heat demand and associated heat recovery in local energy systems which is used for targeting of the minimum energy consumption. In addition, techno-economic analysis is used to provide design guidelines for better heat integration. This design methodology also incorporates the impacts of heat storage and part-load performance of energy production equipment. Opportunities for utilization of low grade heat in process industries have been systematically considered for the minimization of energy generation in local energy systems together with the evaluation of the economic feasibility of such systems for integration of industrial low grade heat with local energy systems. Case studies are used to demonstrate the applicability and practicality of the heat integration methodology developed in this work, and to illustrate how a holistic approach can improve the overall energy efficiency of local energy systems

    Full Text Available The United Nations has designated the year 2012 as the international year of sustainable energy. Today, we are seeing a rise in global awareness of energy consumption and environmental problems. Many nations have launched different programs to reduce the energy consumption in residential and commercial buildings to seek lower-carbon energy solutions. We are talking about the future green and smart houses. The subject of smart/green houses is not one of “why,” but rather “how,” specifically: “how making the future house more energy efficient.” The use of the renewable energy, the technology and the services could help us to answer this question. Intelligent home energy management is an approach to build centralized systems that deliver application functionality as services to end-consumer applications. The objective of this work is to develop a smart and robust controller for house energy consumption with maximizing the use of solar energy and reducing the impact on the power grid while satisfying the energy demand of house appliances. We proposed a fuzzy-based energy management controller in order to reduce the consumed energy of the building while respecting a fixed comfort.

    Taxes, loans and grants, trading schemes and white certificates, public procurement and investment in R&D or infrastructure: known collectively as 'economic instruments', these tools can be powerful means of mobilising the finances needed to achieve policy goals by implementing energy efficiency measures. The role of economic instruments is to kick-start the private financial markets and to motivate private investors to fund EE measures. They should reinforce and promote energy performance regulations. This IEA analysis addresses the fact that, to date, relatively little effort has been directed toward evaluating how well economic instruments work. Using the buildings sector to illustrate how such measures can support energy efficiency, this paper can help policy makers better select and design economic instruments appropriate to their policy objectives and national contexts. This report’s three main aims are to: 1) Examine how economic instruments are currently used in energy efficiency policy; 2) Consider how economic instruments can be more effective and efficient in supporting low-energy buildings; and 3) Assess how economic instruments should be funded, where public outlay is needed. Detailed case studies in this report assess examples of economic instruments for energy efficiency in the buildings sector in Canada (grants), France (tax relief and loans), Germany (loans and grants), Ireland (grants) and Italy (white certificates and tax relief).

  17. Energy Efficiency Policy in Slovenia

    Beravs, F.

    1998-01-01

    When Slovenia gained its independence in 1991, its energy sector was characterised by largely centralised state planning and artificially low prices maintained by widespread subsidies. Supply side considerations tended to dominate the energy policy and sectoral planning. As a result the final energy intensity in Slovenia was (still albeit declining) considerably higher than the EU average. In order to support economic growth and transition to a modern market economy, integrated and competitive in the European and world market structures, the National Assembly of the Republic of Slovenia adopted a resolution on the Strategy of Energy Use and Supply of Slovenia in early 1996. In the field of energy use, the long-term strategic orientation is to increase energy efficiency in all sectors of energy consumption. The main objective can be summarised as to secure the provision of reliable and environmentally friendly energy services at least costs. In quantitative terms the Strategy attaches a high priority to energy efficiency and environmental protection and sets the target of improving the overall energy efficiency by 2% p.a. over the next 10 to 15 years. To achieve the target mentioned above the sectoral approach and a number of policy instruments have been foreseen. Besides market based energy prices which will, according to the European Energy Charter, gradually incorporate the cost of environment and social impacts, the following policy instruments will be intensified and budget-supported: education and awareness building, energy consultation, regulations and agreements, financial incentives, innovation and technology development. The ambitious energy conservation objectives represent a great challenge to the whole society. (author)

    Sathaye, Jayant; Price, Lynn; McNeil, Michael; de la rue du Can, Stephane

    2010-05-01

    This Methodology Booklet provides a comprehensive review and methodology guiding principles for constructing energy efficiency indicators, with illustrative examples of application to individual countries. It reviews work done by international agencies and national government in constructing meaningful energy efficiency indicators that help policy makers to assess changes in energy efficiency over time. Building on past OECD experience and best practices, and the knowledge of these countries' institutions, relevant sources of information to construct an energy indicator database are identified. A framework based on levels of hierarchy of indicators -- spanning from aggregate, macro level to disaggregated end-use level metrics -- is presented to help shape the understanding of assessing energy efficiency. In each sector of activity: industry, commercial, residential, agriculture and transport, indicators are presented and recommendations to distinguish the different factors affecting energy use are highlighted. The methodology booklet addresses specifically issues that are relevant to developing indicators where activity is a major factor driving energy demand. A companion spreadsheet tool is available upon request.

    A review of future trends of energy consumption shows that, in the absence of an active energy policy which promotes energy efficiency, energy consumption will increase as a whole by approximately 6.8% by 2012 continuing to raise after this period.. This result hides large differences between the different sources of energy (mainly heat, fuels and electricity) and between the different sectors - transport, industry, buildings etc. It is therefore clear that a strong energy policy is needed to counterbalance the expected increase in energy consumption in all sectors, with emphasis on measures in the building sector (both residential and tertiary) and in the transport sector. Furthermore improvements in the district heating sector are also essential to prevent further disconnection from district heating and a shift to other means of heating. A review of the main barriers to energy efficiency leads to the conclusion that while significant changes are needed in the regulatory framework, the lack of access to finance and the general lack of awareness about existing technologies and best practice represent the greatest barriers. In order to evaluate the success of energy. In a few studies available from past 2-3 years the calculation of low and high targets for energy policy was elaborated. The low targets would represent about 11% - 12% reduction in overall energy consumption. The high targets would represent a 13% - 15% reduction in overall energy consumption. Policy instruments have been identified which can turn energy efficiency into one of the driving forces of the overall economic and development strategy of the country. Some of these instruments deal with general issues such as general policy issues, regulatory and legal aspects, the institutional framework and fiscal, taxation and pricing policy. They are designed to improve the present conditions and would use only a limited part of the available public budget. The state budget dedicated to energy issues will

    Full Text Available Optimised project delivery methods forsocial housing energy renovations European Social Housing Organisations (SHOs are currently facing challenging times. The ageing of their housing stock and the economic crisis, which has affected both their finances and the finances of their tenants, are testing their capacity to stick to their aim of providing decent and affordable housing. Housing renovation projects offer the possibility of upgrading the health and comfort levels of their old housing stock to current standards and improve energy efficiency, and this solution also addresses the fuel poverty problems suffered by some tenants. Unfortunately, the limited financial capacity of SHOs is hampering the scale of housing renovation projects and the energy savings achieved.  At the same time, the renovation of the existing housing stock is seen as one of the most promising alternative routes to achieving the ambitious CO2 emissions reduction targets set by European authorities – namely, to reduce EU CO2 emissions to 20% below their 1990 levels by 2020. The synergy between European targets and the aims of SHOs has been addressed by the energy policies of the member states, which focus on the potential energy savings achievable by renovating social housing. In fact, the European initiatives have prioritised energy savings in social housing renovations to such an extent that these are referred to as ‘energy renovations’. Energy renovation is therefore a renovation project with higher energy savings target than a regular renovation project. In total, European SHOs own 21.5 million dwellings representing around 9.4% of the total housing stock. Each SHO owns a large number of dwellings, which means there are fewer people to convince of the need to make energy savings through building renovations, maximising the potentially high impact of decisions. Moreover, SHOs are responsible for maintaining and upgrading their properties in order to continue

    Recent Directive 2009/28/EC on the promotion of the use of renewable energies sets some binding targets for the contribution of renewable energies in 2020 to total consumption, setting the share at 20% of final energy demand, with a particularisation of 10% for the transport sector, and also a 20% reduction of greenhouse gases Together with these targets, it also sets another target relative to energy efficiency, aiming for a 20% improvement, under the terms set down by the Commission in its announcement dated 19 October 2006. This energy saving target is going to have a decisive influence on the achievement of the other two. In order to quantify the degree of difficulty of achieving the saving target and determine the policies and measures to be taken, we are going to analyze the evolution of energy efficiency (energy consumption energy units per unit of GDP - economic unit) in Spain from 1980 to date and the value of energy intensity that we should have in 2020 to achieve the targets. This will give us an idea of the magnitude of the challenge and, therefore, of the efforts we will have to make to achieve the target. (Author)

    The demand for energy is increasing in Syria annually by 10-11% and the population increases annually 2.54% This growth leads also to increase in the housing,that it is energy-unconscious and consumes many energy. This large increase in energy consumption is an important problem in the housing in Syria, particularly with the lack of observance of various climatic factors,this leads to install the heating or cooling system in all housing in order to improve thermal comfort. The aim of this work is to provide insights into residential buildings with very high energy efficiency. The starting point is the experience from other countries (such as Germany), which have extensive policies, experience and rules for energy-saving buildings. The aim of this work is to provide insights into residential buildings with very high energy efficiency to win. The starting point is the experience from other countries such as Germany, which has extensive policies and rules for energy-saving buildings have. These are transferred with appropriate additions to residential buildings in Syria, and they are specified for special conditions, as well as the economic, social, climatic and regulatory requirements in Syria.

    This project was initiated to provide design assistance in an effort to maximize energy performance for affordable housing at the Fort Peck Indian Reservation near Poplar, Montana. The Make It Right Foundation (MIRF) built 20 high performing homes (LEED Platinum) in 2015 and 2016 with three (3) different design options. NREL and EPA set out to provide energy analysis along with measurement and verification (M and V) of the homes to characterize energy use and provide clarity for future decision making with regard to tribal housing options. The results included herein summarize the energy end uses and documents projected energy impacts from various aspects of the MIRF home designs and construction. This report includes an analysis of energy use in 5 MIRF homes, comparing energy use across the different styles and configurations. Energy models were created for the 2 styles of MIRF homes, including renewable energy assessment for photovoltaic (PV) systems. Existing tribal housing has also been analyzed, with 5 housing units being analyzed for energy use and an energy model being created for 1 housing unit. The findings of this study highlight many of the challenges that arise when attempting to construct high performance housing in a region where such construction practices are still relatively rare. Homes in Poplar are well designed and, for the most part, and include climate specific design considerations appropriate for northeastern Montana. The most significant issues identified in MIRF homes were related to the work done to put the homes on the foundation, insulate the crawlspaces, and do final connection with the utilities. The Taxed II Credit homes are well designed and well suited to northeastern Montana, and with slight modifications to the design and construction could be very efficient. All occupant comfort and energy usage issues that were identified during the site visits can be remedied through retrofit measures that are relatively inexpensive. Energy

    2016-04-01

    Full Text Available The gas engine driven carbon dioxide heat pump designed for providing the heat, cold and electricity for industrial poultry house is proposed. The scheme differs from the known by using recuperative heat exchanger installed between the exhaust air duct of poultry house and heat pump evaporator and the heat curtain installed on the air duct after the evaporator. The air coming into the poultry house after the regenerative heat exchanger is supplied to the heat pump gas cooler. The heat pump produces heat of the required parameters of the input air and water for watering of poultry, space heating, etc. Heat pump compressor is driven by gas engine (GPA, by natural gas or biogas. The part of the gas-piston engine heat is used for adjusting the optimal heat pump mode and for regeneration of the absorbent in an evaporative cooler. The proposed technical solution of the above scheme provides a higher COP of the heat pump. Installing of heat curtain does not require the use of non-freezing solution to prevent icing of the air outlet of heat pump evaporator. The latter allows producing, besides electric power and heat, still cold (with the use off the adsorption-refrigerating machine and provide drying air inlet evaporative cooler (if necessary.

    Full Text Available In this paper we present a heterogeneous collaborative sensor network for electrical management in the residential sector. Improving demand-side management is very important in distributed energy generation applications. Sensing and control are the foundations of the “Smart Grid” which is the future of large-scale energy management. The system presented in this paper has been developed on a self-sufficient solar house called “MagicBox” equipped with grid connection, PV generation, lead-acid batteries, controllable appliances and smart metering. Therefore, there is a large number of energy variables to be monitored that allow us to precisely manage the energy performance of the house by means of collaborative sensors. The experimental results, performed on a real house, demonstrate the feasibility of the proposed collaborative system to reduce the consumption of electrical power and to increase energy efficiency.

    The UK government has an ambitious goal to reduce carbon emissions from the housing stock through energy efficiency improvements. This single policy goal is a strong driver for change in the housing system, but comes with positive and negative "unintended consequences" across a broad range of outcomes for health, equity and environmental sustainability. The resulting policies are also already experiencing under-performance through a failure to consider housing as a complex system. This research aimed to move from considering disparate objectives of housing policies in isolation to mapping the links between environmental, economic, social and health outcomes as a complex system. We aimed to support a broad range of housing policy stakeholders to improve their understanding of housing as a complex system through a collaborative learning process. We used participatory system dynamics modelling to develop a qualitative causal theory linking housing, energy and wellbeing. Qualitative interviews were followed by two interactive workshops to develop the model, involving representatives from national and local government, housing industries, non-government organisations, communities and academia. More than 50 stakeholders from 37 organisations participated. The process resulted in a shared understanding of wellbeing as it relates to housing; an agreed set of criteria against which to assess to future policy options; and a comprehensive set of causal loop diagrams describing the housing, energy and wellbeing system. The causal loop diagrams cover seven interconnected themes: community connection and quality of neighbourhoods; energy efficiency and climate change; fuel poverty and indoor temperature; household crowding; housing affordability; land ownership, value and development patterns; and ventilation and indoor air pollution. The collaborative learning process and the model have been useful for shifting the thinking of a wide range of housing stakeholders towards a more

    In previous studies, econometric methods have been used to analyze the impact of market transformation programs. This paper reviewed the results of a detailed assessment of United States lighting markets. The study utilized market analysis to understand the impact of energy conservation policy developments on sales of energy efficient screw-type lamps and linear fluorescent lamps. The paper described the methods used and hypotheses for the study. The study approach involved three steps. First, a database of product sales and drivers of product sales by efficiency type information from annual surveys of sales of lighting products was built. In order to model the impact of gross domestic product, electricity prices and demand side management on product sales for energy efficient and standard products, ordinary least squares regression analysis was used. The regression output was then used alongside the database information to estimate the impact of changes in electricity prices, gross domestic product and demand side marketing activity on sales of energy efficient and standard products. Results were presented for annual sales and market share information for screw-type lamps purchased by residential and small business customers; lamp sales regressions and compact fluorescent lamp sales analysis; an analysis of incandescent lamp sales and regressions of linear fluorescent tubes sales; and annual sales and market share information for linear fluorescent tubes purchased by residential and small business customers as well as regression results. It was concluded that the total effect was an increase in sales of compact fluorescent lamps of 13.3 million units in 2002, 17.7 million units in 2003 and 22.7 million units in 2004. 5 refs., 8 tabs.

    Full Text Available Computers, laptops and mobile devices – information technology (IT accounts for 2% of human greenhouse gas emissions worldwide, as evidenced in a study by Global Action Plan, a UK based environmental organization. This figure can be reduced if the green segment, or Green IT, continues to grow. Energy can also be saved through cloud computing, namely the principle of outsourcing the programs and functions of one’s own computer to service providers over the internet. This also means sharing storage capacity with others. This paper highlights the impact of information technology applications towards enhancing energy efficiency of the systems.

    Highlights: • Mathematical simulation model of an integrated PV solar house was proposed. • Developed model was validated with results available in the literature. • A solar house size of 12–24 m 3 /1 m 2 of collector area satisfies heating conditions. • A flow rate of 0.06 kg/s is accepted for a size of 24 m 3 /1 m 2 collector area. • Longitudinal configuration for the solar cell array is preferred. - Abstract: This paper concerns with optimum design and performance parameters related to energy management of a small solar house. The house is designed to satisfy the main requirements of electrical power and space heating. The proposed house has a south facing PV module employed for direct converting of solar energy into electricity as well as an air solar collector that is integrated behind the solar module. Integration of the solar collector with the PV module aims to enhance the efficiency as well as to decrease the capital cost of the unit. A heat and mass flow numerical model for the energy and mass balances of the flowing air behind the PV module is developed. Temperature variation of individual rooms inside the house is also considered in the study. The developed model has been employed to determine: an appropriate size for the solar house as regards to the given area of PV module, the optimum mass flow rate through the solar collector, and the best configuration of the solar cell array. The simulation results show that an area of 2 m 2 of the PV module would satisfy an acceptable room temperature in the season of winter with a solar house size of 24–48 m 3 . Besides, there would be a significant enhancement in thermal efficiency at high mass flow rate of flowing air through the system. Furthermore, higher thermal efficiency and an acceptable room temperature would be achieved in longitudinal configuration of PV module

    that EnergyPlus did not capture the heating-side behavior of heat pumps particularly accurately, and that our simple oil furnace and boiler models needed significant recalibration to fit with RECS. Simulating the full RECS sample on a single computer would take many hours, so we used the 'cloud computing' services provided by Amazon.com to simulate dozens of homes at once. This enabled us to simulate the full RECS sample, including multiple versions of each home to evaluate the impact of marginal changes, in less than 3 hours. Once the tool was calibrated, we were able to address several policy questions. We made a simple measurement of the heat replacement effect and showed that the net effect of heat replacement on primary energy use is likely to be less than 5%, relative to appliance-only measures of energy savings. Fuel switching could be significant, however. We also evaluated the national and regional impacts of a variety of 'overnight' changes in building characteristics or occupant behavior, including lighting, home insulation and sealing, HVAC system efficiency, and thermostat settings. For example, our model shows that the combination of increased home insulation and better sealed building shells could reduce residential natural gas use by 34.5% and electricity use by 6.5%, and a 1 degree rise in summer thermostat settings could save 2.1% of home electricity use. These results vary by region, and we present results for each U.S. Census division. We conclude by offering proposals for future work to improve the tool. Some proposed future work includes: comparing the simulated energy use data with the monthly RECS bill data; better capturing the variation in behavior between households, especially as it relates to occupancy and schedules; improving the characterization of recent construction and its regional variation; and extending the general framework of this simulation tool to capture multifamily housing units, such as apartment buildings.

    Photovoltaic power generation system was once placed in excessive expectation what with a growing tendency toward environmental issues and what with vulnerability in supply and demand of energy. However, its utilization was negative because of the low energy conversion efficiency and the high cost. Then, gradually the wind shifted round to the improvement in solar cell efficiency, reduced cost, implementation of subsidizing policy by MITI, purchase of excess power by electric power companies and the amendment of the Electricity Enterprises Act, encouraging the use of the system again. In addition, with a lesson from the Great Hanshin Earthquake, the merit of the system was appreciated as a life-support power source, motivating house-builders. Earlier, the authors had reported designs of energy-saving homes, system structures of photovoltaic power generation, etc. This paper presents the power generation record of a year old system and an example of the comfortable sealed residential room environment, etc., created with the use of the power thus obtained. The annual power generation was 4,088kWh, 30% of which was used in the house and 70% of which was sold as an excess power, resulting in the purchase of power for 6,642kWh. 5 refs., 4 figs, 2 tabs.

    1999-04-01

    The project referred to in the heading concentrated on energy use and carbon dioxide emissions relating to heating of houses in Norway. There are many ways of reducing energy use and carbon dioxide emissions, but the measures taken are often unprofitable because of high investment costs and relatively moderate energy prices. The development of society, environmental policy and technology strongly affects the development and management of the buildings, and this project could only elucidate a limited number of approaches of current interest. About 60% of the energy needed for heating houses comes from electricity, and the use of electricity for general purposes is increasing. Norway will probably become a major net importer of electric power within a few years unless strong measures are taken. Most of the carbon dioxide emission from buildings are due to oil fuel firing

  18. Housing, energy cost, and the poor: Counteracting effects in Germany's housing allowance program

    International Nuclear Information System (INIS)

    Groesche, Peter

    2010-01-01

    Adequate housing and affordable warmth are essential human needs, the lack of which may seriously harm people's health. Germany provides an allowance to low-income households, covering the housing as well as the space heating cost, to protect people from the consequences of poor housing conditions and fuel poverty. In order to limit public expenditures, payment recipients are required to choose low-cost dwellings, with the consequence that they probably occupy flats with a poor thermal performance. Recipients might therefore exhibit a lower per-square meter rent but in turn are likely to have a higher energy consumption and energy expenditures. Using a large data set of German households, this paper demonstrates that this financially counteracting effect is of negligible magnitude.

    Lighting upgrades including neon to LED, incandescent to CFL's and T-12 to T-8 and T-5's were completed through this grant. A total of 16 Chickasaw nation facilities decreased their carbon footprint because of these grant funds. Calculations used were based on comparing the energy usage from the previous year's average and the current energy usage. For facilities without a full year's set of energy bills, the month after installation was compared to the same month from the previous year. Overall, the effect the lighting change-outs had for the gaming centers and casinos far exceeded expectations. For the Madill Gaming Center; both an interior and exterior upgrade was performed which resulted in a 31% decrease in energy consumption. This same reduction was seen in every facility that participated in the grant. Just by simply changing out light bulbs to newer energy efficient equivalents, a decrease in energy usage can be achieved and this was validated by the return on investment seen at Chickasaw Nation facilities. Along with the technical project tasks were awareness sessions presented at Chickasaw Head Starts. The positive message of environmental stewardship was passed down to head start students and passed along to Chickasaw employees. Excitement was created in those that learned what they could do to help reduce their energy bills and many followed through and took the idea home. For a fairy low cost, the general public can also use this technique to lower their energy consumption both at home and at work. Although the idea behind the project was somewhat simple, true benefits have been gained through environmental awareness and reductions of energy costs.

  2. Energy Efficiency in Manufacturing Systems

    2012-01-01

    Energy consumption is of great interest to manufacturing companies. Beyond considering individual processes and machines, the perspective on process chains and factories as a whole holds major potentials for energy efficiency improvements. To exploit these potentials, dynamic interactions of different processes as well as auxiliary equipment (e.g. compressed air generation) need to be taken into account. In addition, planning and controlling manufacturing systems require  balancing technical, economic and environmental objectives. Therefore, an innovative and comprehensive methodology – with a generic energy flow-oriented manufacturing simulation environment as a core element – is developed and embedded into a step-by-step application cycle. The concept is applied in its entirety to a wide range of case studies such as aluminium die casting, weaving mills, and printed circuit board assembly in order to demonstrate the broad applicability and the benefits that can be achieved.

    The purpose of the study is to present new methods or new products that could save money while improving the environment in Lebanon. Cost of energy is on the increase and is predicted to increase even more in the future. Environmental issues and awareness are gaining momentum in Lebanon. With electricity production directly linked to power plants that represent about 30% of the air pollution which is also linked to health related issues. There is an intermediate need to introduce more energy efficient products in the construction industry which require less energy to operate or could be linked indirectly to energy. In this context, cost-benefit analysis of heating, light, painting, energy consumption and energy lamp burning hours in addition to fuel burner, gas and electric heater in buildings are presented in tables. Finally, there is a lack of awareness on the positive impact on the environment reflected in the saving of natural resources, reducing pollution and creation of a better living environment

  4. Exploring the Housing and Household Energy Pathways to Stress: A Mixed Methods Study

    Full Text Available Chronic stress, known to contribute to negative physical and mental health outcomes, is closely associated with broader issues of material hardship, poor neighborhood conditions, residential instability, and inadequate housing conditions. However, few studies have comprehensively explored pathways to stress in a low-income housing environment. A mixed-methods pilot study investigated the concept of energy insecurity by looking at the impacts of weatherization and energy efficiency interventions on low-income households in the South Bronx neighborhood of New York City. In-depth interviews were conducted with 20 low-income heads of household; participants also completed health, housing and budget assessments. Physical deficiencies, economic hardship, and health issues all interacted to directly and indirectly produce living conditions that contribute to chronic stress. Households with higher stress reported more health problems. Poor quality housing led to coping responses that increased expenses, which in turn increased stress around housing and energy affordability. This study provides further support for the connections between both health and the built environment and between low socio-economic status populations and net negative health outcomes. Energy insecurity is an important contributor to chronic stress in low-income households, and isolating pathways to stress where there is potential for interventions is important for future policy and housing-based strategies.

    On behalf of the Swedish Energy Agency, SP has investigated and recommended how one could form a platform for demonstration of single family houses as nearly zero energy houses. SP suggests that TMF, the national trade and employers' association of the wood processing and furniture industry in Sweden, should administrate this platform. The reason being that members of TMF produce almost 80% of all single family houses in Sweden. TMF also has the capacity to launch a demonstration platform in a reasonable short time. SP has also compiled a set on technical criteria regarding properties related to energy use that should be met by demonstration projects within the platform. One presumption has been that a house that meets the criteria in the south of Sweden also should meet the criteria in the north of Sweden. The reason being to promote an industrialized and cost effective building process. Another ambition has been not to disfavor smaller single family houses. The main criteria are on very energy efficient building envelopes and very efficient building services systems. The criteria are therefore more detailed than the current Swedish building regulations

  13. Energy Vulnerability Composite Index in Social Housing, from a Household Energy Poverty Perspective

    Directory of Open Access Journals (Sweden)

    Eva Llera-Sastresa

    2017-04-01

    Full Text Available In Europe, the proportion of social housing is high, and such houses tend to be inhabited by below average-income households, which are particularly vulnerable to energy poverty. This article proposes a new methodological approach for defining an index for household energy vulnerability assessment. This method can be used to improve the management of social housing. After establishing a heuristic framework for household energy poverty–which stems from different causes such as income, the characteristics of the residence, energy installations, and the energy-consumption habits of household members–multi-criteria analytical methods, based on the aggregation of indicators which reveal the conditions leading to energy poverty, have been applied, and effective means of intervention are proposed. The method is also applied to a sample of social houses and thus validated as a useful tool in decision-making processes which concern the management of social housing from a household energy-poverty perspective.

    1995-10-01

    Energy efficiency is a vital component of the Nation`s energy strategy. One of the Department of Energy`s missions are to promote energy efficiency to help the Nation manage its energy resources. The ability to define and measure energy efficiency is essential to this objective. In the absence of consistent defensible measures, energy efficiency is a vague, subjective concept that engenders directionless speculation and confusion rather than insightful analysis. The task of defining and measuring energy efficiency and creating statistical measures as descriptors is a daunting one. This publication is not a final product, but is EIA`s first attempt to define and measure energy efficiency in a systematic and robust manner for each of the sectors and the United States economy as a whole. In this process, EIA has relied on discussions, customer reviews, in-house reviews, and seminars that have focused on energy efficiency in each of the sectors. EIA solicits the continued participation of its customers in further refining this work.

    Latief, Y.; Berawi, M. A.; Koesalamwardi, A. B.; Supriadi, L. S. R.

    2018-03-01

    Near Zero Energy House (NZEH) is a housing building that provides energy efficiency by using renewable energy technologies and passive house design. Currently, the costs for NZEH are quite expensive due to the high costs of the equipment and materials for solar panel, insulation, fenestration and other renewable energy technology. Therefore, a study to obtain the optimum design of a NZEH is necessary. The aim of the optimum design is achieving an economical life cycle cost performance of the NZEH. One of the optimization methods that could be utilized is Genetic Algorithm. It provides the method to obtain the optimum design based on the combinations of NZEH variable designs. This paper discusses the study to identify the optimum design of a NZEH that provides an optimum life cycle cost performance using Genetic Algorithm. In this study, an experiment through extensive design simulations of a one-level house model was conducted. As a result, the study provide the optimum design from combinations of NZEH variable designs, which are building orientation, window to wall ratio, and glazing types that would maximize the energy generated by photovoltaic panel. Hence, the design would support an optimum life cycle cost performance of the house.

We analyze the following modes of operation; event detection, sleep(wake-up), data acquisition, data processing modes using low power, high performance embedded technology such as specialized embedded DSP processors and a low power FPGAs at the sensing node. We use compute intensive sensor node applications: an acoustic vehicle classifier (frequency domain analysis) and a video license plate identification application (learning algorithm) as a case study. We report performance and total energy usage for our system implementations and discuss the system architecture design trade offs.

    The Department of Energy’s (DOE’s) Pacific Northwest National Laboratory (PNNL) was tasked by the DOE Office of Electricity (OE) to recommend load reduction and grid integration strategies, and identify additional demand response (energy efficiency/conservation opportunities) and strategies at the Forest City Housing (FCH) redevelopment at Pearl Harbor and the Marine Corps Base Hawaii (MCBH) at Kaneohe Bay. The goal was to provide FCH staff a path forward to manage their electricity load and thus reduce costs at these FCH family housing developments. The initial focus of the work was at the MCBH given the MCBH has a demand-ratchet tariff, relatively high demand (~18 MW) and a commensurate high blended electricity rate (26 cents/kWh). The peak demand for MCBH occurs in July-August. And, on average, family housing at MCBH contributes ~36% to the MCBH total energy consumption. Thus, a significant load reduction in family housing can have a considerable impact on the overall site load. Based on a site visit to the MCBH and meetings with MCBH installation, FCH, and Hawaiian Electric Company (HECO) staff, recommended actions (including a "smart grid" recommendation) that can be undertaken by FCH to manage and reduce peak-demand in family housing are made. Recommendations are also made to reduce overall energy consumption, and thus reduce demand in FCH family housing.

    The development of net zero energy homes can be attributed to the growing interest in sustainable and energy efficient housing. Net zero energy homes are residential units that consume as much energy as they produce. Their basic design methodology consists of developing a highly insulated building envelope to minimize the energy consumption, along with a viable source of renewable energy for energy production. A comprehensive analysis of the technical and economic feasibility of net zero energy housing within Canada was conducted. A TRNSYS modeling tool developed by the Canadian Center for Housing Technology (CCHT) and Natural Resources Canada was used for the simulations. Any modifications that were made to the building used the tool as the base. The project consisted of two identical houses, with one serving as a reference and the other for testing advanced technologies. The houses were built in 1998 and conform to the R-2000 standard. The impact of insulation level on energy consumption was examined through the use of sensitivity analysis. RSI-10 was found to be the most suitable insulation level for most of the 12 Canadian cities used in this study. An air-source heat pump that provides relatively high COP even at colder temperatures was found to be a practical and an ideal solution for Canadian environment. Photovoltaics were used for meeting electricity needs, and a solar domestic hot water heater was supplemented with a backup electrical element to meet the hot water needs. The feasibility study focused on energy performance as well as the economic and payback cost of building a net zero energy home. The prevalent price of electricity in a particular region determined whether a project was feasible. Nunavut was found to have the shortest payback of only 7 years, while Montreal had the longest at 59 years. 24 refs., 8 tabs., 4 figs.

    2010-01-01

    Full Text Available Energy efficient computing has recently become hot research area. Many works have been carried out on conserving energy, but considering energy efficiency in grid computing is few. This paper proposes energy efficient resource management in mobile grid. The objective of energy efficient resource management in mobile grid is to maximize the utility of the mobile grid which is denoted as the sum of grid application utility. The utility function models benefits of application and system. By using nonlinear optimization theory, energy efficient resource management in mobile grid can be formulated as multi objective optimization problem. In order to derive a distributed algorithm to solve global optimization problem in mobile grid, we decompose the problem into the sub problems. The proposed energy efficient resource management algorithm decomposes the optimization problem via iterative method. To test the performance of the proposed algorithm, the simulations are conducted to compare proposed energy efficient resource management algorithm with other energy aware scheduling algorithm.

  16. The role of the Government Energy Efficiency Act in the National Energy Act of 1992

    Good, L.; Williams, D.R.

    1993-01-01

    Last year Senator John Glenn's Government Energy Efficiency Act to reform energy management in the Federal Government was adopted entirely into the Senate's comprehensive energy bill. This year key portions of an equivalent bill were incorporated into the House of Representatives comprehensive energy bill after intensive lobbying by AEE's National Capital Chapter. According to a House staffer who played a key role in the bill, the section on energy manager training was included as a direct result of the Chapter's persuasion. Each bill passed in its respective house. At the time of this writing, in the spring of 1992, the two houses are scheduled to go into conference and attempt to merge their separate bills into one National Energy Act of 1992. The 102nd Congress seems determined to establish a national energy policy before election time, but the two houses take very different approaches to the problem, The bill could be voted into law during or just before the 15th World Energy Engineering Congress (WEEC). This paper will discuss some of the strengths and loopholes that apply to the Federal sector. The presentation of this paper at WEEC in October will bring AEE members up to the minute on these developments

    Christian, Jeffrey E [ORNL; Bonar, Jacob [ORNL

    2011-10-01

    This report describes a home that uses 40% less energy than the energy-efficient Building America standard - a giant step in the pursuit of affordable near-zero-energy housing through the evolution of five near-zero-energy research houses. This four-bedroom, two-bath, 1232-ft2 house has a Home Energy Rating System (HERS) index of 35 (a HERS rating of 0 is a zero-energy house, a conventional new house would have a HERS rating of 100), which qualifies it for federal energy efficiency and solar incentives. The house is leading to the planned construction of a similar home in Greensburg, Kansas, and 21 staff houses in the Walden Reserve, a 7000-unit "deep green" community in Cookville, Tennessee. Discussions are underway for construction of similar houses in Charleston, South Carolina, Seattle, Washington, Knoxville and Oak Ridge, Tennessee, and upstate New York. This house should lead to a 40% and 50% Gate-3, Mixed-Humid-Climate Joule for the DOE Building America Program. The house is constructed with structurally-insulated-panel walls and roof, raised metal-seam roof with infrared reflective coating, airtight envelope (1.65 air changes per hour at 50 Pascal), supply mechanical ventilation, ducts inside the conditioned space, extensive moisture control package, foundation geothermal space heating and cooling system, ZEHcor wall, solar water heater, and a 2.2 kWp grid-connected photovoltaic (PV) system. The detailed specifications for the envelope and the equipment used in ZEH5 compared to all the houses in this series are shown in Tables 1 and 2. Based on a validated computer simulation of ZEH5 with typical occupancy patterns and energy services for four occupants, energy for this all-electric house is predicted to cost only $0.66/day ($0.86/day counting the hookup charges). By contrast, the benchmark house would require $3.56/day, including hookup charges (these costs are based on a 2006 residential rates of $0.07/kWh and solar buyback at $0.15/kWh). The solar

We prove the advantages of using the network form of organizational and economic support implementation of energy saving projects.

  20. Market conditions affecting energy efficiency investments

    International Nuclear Information System (INIS)

    Seabright, J.

    1996-01-01

    The global energy efficiency market is growing, due in part to energy sector and macroeconomic reforms and increased awareness of the environmental benefits of energy efficiency. Many countries have promoted open, competitive markets, thereby stimulating economic growth. They have reduced or removed subsidies on energy prices, and governments have initiated energy conservation programs that have spurred the wider adoption of energy efficiency technologies. The market outlook for energy efficiency is quite positive. The global market for end-use energy efficiency in the industrial, residential and commercial sectors is now estimated to total more than $34 billion per year. There is still enormous technical potential to implement energy conservation measures and to upgrade to the best available technologies for new investments. For many technologies, energy-efficient designs now represent less than 10--20% of new product sales. Thus, creating favorable market conditions should be a priority. There are a number of actions that can be taken to create favorable market conditions for investing in energy efficiency. Fostering a market-oriented energy sector will lead to energy prices that reflect the true cost of supply. Policy initiatives should address known market failures and should support energy efficiency initiatives. And market transformation for energy efficiency products and services can be facilitated by creating an institutional and legal structure that favors commercially-oriented entities

  1. Energy performance ratings and house prices in Wales: An empirical study

    International Nuclear Information System (INIS)

    Fuerst, Franz; McAllister, Pat; Nanda, Anupam; Wyatt, Pete

    2016-01-01

    This paper investigates the effect of Energy Performance Certificate (EPC) ratings on residential prices in Wales. Drawing on a sample of approximately 192,000 transactions, the capitalisation of energy efficiency ratings into house prices is investigated using two approaches. The first adopts a cross-sectional framework to investigate the effect of EPC rating on price. The second approach applies a repeat-sales methodology to investigate the impact of EPC rating on house price appreciation. Statistically significant positive price premiums are estimated for dwellings in EPC bands A/B (12.8%) and C (3.5%) compared to houses in band D. For dwellings in band E (−3.6%) and F (−6.5%) there are statistically significant discounts. Such effects may not be the result of energy performance alone. In addition to energy cost differences, the price effect may be due to additional benefits of energy efficient features. An analysis of the private rental segment reveals that, in contrast to the general market, low-EPC rated dwellings were not traded at a significant discount. This suggests different implicit prices of potential energy savings for landlords and owner-occupiers.

  2. An analysis of household energy use by racial/ethnic composition: Consumption, efficiency, and lifestyles

    Science.gov (United States)

    Valenzuela, Carlos

    The goal of this dissertation is to provide the most recent household energy consumption analysis by racial/ethnic household composition. This dissertation found that significant differences in behavior, energy consumption, and energy efficiency exist by racial/ethnic household composition. The models suggest that behavioral energy intensity is lower among households led by racial/ethnic minorities. Energy consumption and efficiency models suggest that Hispanic households consume less energy and are more efficient, while Black households consume more energy and are less efficient, than White households. However, when stratifying the models by housing vintage, the differences between Hispanic and White households are not consistent. Differences between Black and White households are evident only among those in housing units built before 1980, indicating that Black households in older vintages live in less efficient housing units and could be at a disadvantage that could result in having to pay a higher share of household income on energy use. Results also point towards evidence that energy efficiency standards since the late 1970s could have actually mitigated potential inequality associated with excess energy use by race/ethnicity. Improving energy efficiency of housing units may be beneficial not only to reduce total energy consumption levels, but also have the potential to lessen the burden of energy costs that lower income households (irrespective of race/ethnicity) might experience otherwise.

    Full Text Available This work evaluates the potential for the reduction of energy demand in residential buildings by acting on the exterior envelope, both in newly constructed buildings and in the retrofitting of existing stock. It focuses on analysing social housing buildings in Mediterranean areas and on quantifying the scope of that reduction in the application of different envelope design strategies, with the purpose of prioritizing their application based on their energy efficiency. The analyses and quantifications were made by means of the generation of energy models with the TRNSYS tool for simple or combined solutions, identifying possible potentials for reduction of the energy demand from 20% to 25%, basically by acting on the windows. The case study was a newly built social housing building of a closed block type located in Seville (Spain. Its constructive techniques and the insulation level of its envelope are standardized for current buildings widespread across Mediterranean Europe.

    Wallpe, Jordan P.

    The purpose of this research was to evaluate affordable technologies that are capable of providing attractive, cost-effective energy savings to the housing industry. The research did so by investigating the 2011 Solar Decathlon competition, with additional insight from the Purdue INhome. Insight from the Purdue INhome verified the importance of using a three step design process to design a net-zero energy building. In addition, energy consumption values of the INhome were used to compare and contrast different systems used in other houses. Evaluation of unbiased competition contests gave a better understanding of how a house can realistically reach net-zero. Upon comparison, off-the-shelf engineering systems such as super-efficient HVAC units, heat pump hot water heaters, and properly designed photovoltaic arrays can affordably enable a house to become net-zero. These important and applicable technologies realized from the Solar Decathlon will reduce the 22 percent of all energy consumed through the residential sector in the United States. In conclusion, affordable net-zero energy buildings can be built today with commitment from design professionals, manufacturers, and home owners.

    2013-09-01

    Full Text Available The small medium large system (SMLsystem is a house built at the Universidad CEU Cardenal Herrera (CEU-UCH for participation in the Solar Decathlon 2013 competition. Several technologies have been integrated to reduce power consumption. One of these is a forecasting system based on artificial neural networks (ANNs, which is able to predict indoor temperature in the near future using captured data by a complex monitoring system as the input. A study of the impact on forecasting performance of different covariate combinations is presented in this paper. Additionally, a comparison of ANNs with the standard statistical forecasting methods is shown. The research in this paper has been focused on forecasting the indoor temperature of a house, as it is directly related to HVAC—heating, ventilation and air conditioning—system consumption. HVAC systems at the SMLsystem house represent 53:89% of the overall power consumption. The energy used to maintain temperature was measured to be 30%–38:9% of the energy needed to lower it. Hence, these forecasting measures allow the house to adapt itself to future temperature conditions by using home automation in an energy-efficient manner. Experimental results show a high forecasting accuracy and therefore, they might be used to efficiently control an HVAC system.

    1998-09-01

    A key challenge facing post-apartheid South Africa is to achieve a balance between equity and efficiency goals. On the one hand, the democratic government wishes to improve the quality of life of the majority of the population, whilst on the other, the country needs an efficient and internationally competitive economy. At the more specific level of household energy policy, this efficiency-equity linkage represents a key challenge for policy-making and implementation: it is essential that convergence is sought between household energy strategies aimed at improving energy efficiency, and those strategies which improve the living conditions of the poor. This paper begins by reviewing developments in South Africa`s household energy sector in the early-1990s, most notably the national electrification plan which was launched in 1991. A second development, in 1994, was the establishment of the National Electricity Regulator. Despite the attention given to energy efficiency in the government`s new energy policy, energy efficiency considerations have not yet emerged as a major force in the energy sector. Electricity prices underestimated the environmental and other impacts of coal and nuclear-generated electricity. A range of economic and institutional reasons for this are identified and considered. Finally, two interventions on which some progress has been made, are described: these include insulation and thermal performance projects in new lost-cost houses, and a compact fluorescent lighting programme. 37 refs., 4 figs.

  11. Measuring energy efficiency: Is energy intensity a good evidence base?

    International Nuclear Information System (INIS)

    Proskuryakova, L.; Kovalev, A.

    2015-01-01

    Highlights: • Energy intensity measure reflects consumption, not energy efficiency. • Thermodynamic indicators should describe energy efficiency at all levels. • These indicators should have no reference to economic or financial parameters. • A set of energy efficiency indicators should satisfy several basic principles. • There are trade-offs between energy efficiency, power and costs. - Abstract: There is a widespread assumption in energy statistics and econometrics that energy intensity and energy efficiency are equivalent measures of energy performance of economies. The paper points to the discrepancy between the engineering concept of energy efficiency and the energy intensity as it is understood in macroeconomic statistics. This double discrepancy concerns definitions (while engineering concept of energy efficiency is based on the thermodynamic definition, energy intensity includes economic measures) and use. With regard to the latter, the authors conclude that energy intensity can only provide indirect and delayed evidence of technological and engineering energy efficiency of energy conversion processes, which entails shortcomings for management and policymaking. Therefore, we suggest to stop considering subsectoral, sectoral and other levels of energy intensities as aggregates of lower-level energy efficiency. It is suggested that the insufficiency of energy intensity indicators can be compensated with the introduction of thermodynamic indicators describing energy efficiency at the physical, technological, enterprise, sub-sector, sectoral and national levels without references to any economic or financial parameters. Structured statistical data on thermodynamic efficiency is offered as a better option for identifying break-through technologies and technological bottle-necks that constrain efficiency advancements. It is also suggested that macro-level thermodynamic indicators should be based on the thermodynamic first law efficiency and the energy

    1990-01-01

    Policies that promote energy efficiency can work; but potential energy savings are unlikely to be realized without effective policy leadership. This article discusses the opportunities in several countries for increasing energy efficiency. Both ''open'' and centrally planned economies could be much more energy efficient. In the United States, for example, the government needs to stimulate energy efficiency. This could be done by sponsoring research to develop new processes, creating favourable financial conditions for investment in efficiency, and making the advantages of energy efficiency technologies better known. International collaboration in sponsoring research and transfer technologies could be of the greatest importance in improving energy efficiency in countries with centrally planned economies, including the Soviet Union, as well as in developing countries. Favourable conditions for achieving both economic development and environmental protection can be created through cooperation on the international level. (author). 24 refs, 4 tabs

  13. State-Level Benefits of Energy Efficiency

    Energy Technology Data Exchange (ETDEWEB)

    Tonn, Bruce Edward [ORNL

    2007-02-01

    This report describes benefits attributable to state-level energy efficiency programs. Nationwide, state-level energy efficiency programs have targeted all sectors of the economy and have employed a wide range of methods to promote energy efficiency. Standard residential and industrial programs typically identify between 20 to 30% energy savings in homes and plants, respectively. Over a 20 year period of time, an average state that aggressively pursues even a limited array of energy efficiency programs can potentially reduce total state energy use by as much as 20%. Benefit-cost ratios of effective energy efficiency programs typically exceed 3 to 1 and are much higher when non-energy and macroeconomic benefits are included. Indeed, energy efficiency and associated programs and investments can create significant numbers of new jobs and enhance state tax revenues. Several states have incorporated energy efficiency into their economic development programs. It should also be noted that increasing amounts of venture capital are being invested in the energy sector in general and in specific technologies like solar power in particular. Well-designed energy efficiency programs can be expected to help overcome numerous barriers to the market penetration of energy efficient technologies and accelerate the market penetration of the technologies.

    The performance of mobile soft robots is usually characterized by their locomotion/velocity efficiency, whereas the energy efficiency is a more intrinsic and fundamental criterion for the performance evaluation of independent or integrated soft robots. In this work, a general framework is established to evaluate the energy efficiency of mobile soft robots by considering the efficiency of the energy source, actuator and locomotion, and some insights for improving the efficiency of soft robotic systems are presented. Proposed as the ratio of the desired locomotion kinetic energy to the input mechanical energy, the energy efficiency of locomotion is found to play a critical role in determining the overall energy efficiency of soft robots. Four key factors related to the locomotion energy efficiency are identified, that is, the locomotion modes, material properties, geometric sizes, and actuation states. It is found that the energy efficiency of most mobile soft robots reported in the literature is surprisingly low (mostly below 0.1%), due to the inefficient mechanical energy that essentially does not contribute to the desired locomotion. A comparison of the locomotion energy efficiency for several representative locomotion modes in the literature is presented, showing a descending ranking as: jumping ≫ fish-like swimming > snake-like slithering > rolling > rising/turning over > inchworm-like inching > quadruped gait > earthworm-like squirming. Besides, considering the same locomotion mode, soft robots with lower stiffness, higher density and larger size tend to have higher locomotion energy efficiency. Moreover, a periodic pulse actuation instead of a continuous actuation mode may significantly reduce the input mechanical energy, thus improving the locomotion energy efficiency, especially when the pulse actuation matches the resonant states of the soft robots. The results presented herein indicate a large and necessary space for improving the locomotion energy

    Energy devices and buildings are sustainable if, when they operate, they use sustainable (renewable and refuse) energy and generate nega-energy. This paper covers three research examples of this type of sustainability: (1) use of air-to-earth heat exchangers, (2) computer control of heating and cooling of the building (via heat pumps and heat-recovery devices), and (3) design control of energy consumption in a house.

    Full Text Available Life stock is the major sector of agriculture which is of great importance for Pakistan. It has a major contribution towards the economy of Pakistan with a 55.9 participation in agriculture sector. Pakistan is fourth largest country in milk production with 50.9 Billion tons per annum out of which only 5 is processed and pasteurized hardly and remaining milk is handled by milk men under non-hygienic conditions which causes milk borne diseases. Milk is perishable food having shelf life of few hours therefore milk processing is done to deactivate the microorganisms in the milk and increase its shelf life for future use. It is an energy intensive process and mostly conventional form of energy is used for this purpose. Solar power is the sustainable source of energy and there is an average solar global radiation of 5.3kWhm2day persist in the country with more than 300 sunny days in a year. The objective of the study was to design and develop a solar assisted milk pasteurizer and to evaluate its performance. The developed solar assisted milk pasteurizer consisted of heating and cooling unit. Heating unit made of shell and tube type coil to heat up the milk up-to 730C for 15 seconds. Cooling unit has a chiller for sudden cool down the milk from 350C to 40C within 2 hours. Solar milk chiller had capacity of 200 liters chiller semicircular pug mill type SS-304 a 2kWp PV system having eight PV modules each of 250Wp a hybrid inverter 3kVA that convert 24V DC current into 220V AC current and two batteries 150Ah each as a backup source to meet weather fluctuations. One ton of vapor compression refrigeration system was filled with R410a refrigerant with inlet pressure of 118psi and the outlet pressure of 300psi was coupled with the chiller through coils at bottom side of the vessel. An agitator was installed with a lid on the tank to stir the milk continuously inside the chiller to make sure that homogeneous milk cooling to avoid freezing of the milk in the

  17. Radon and energy efficient homes

    Radon and its daughters in indoor air are presently responsible for dose equivalents of about 31 mSv/year (3 rem/year) to parts of the respiratory tract. Linear extrapolation from the dose response values of uranium miners heavily exposed to radon and its decay products would suggest that almost all lung cancers in the non-smoking population are caused by environmental 222 Rn. Using epidemiological data on the types of lung cancer found in non-smokers of the general public as compared to the miners, a smaller effect of low level radon exposure is assumed, which would result in a lung cancer mortality rate due to radon of about 10 deaths per year and million or 25% of the non-smoker rate. Higher indoor radon concentrations in energy efficient homes mostly caused by reduced air exchange rates will lead to a several fold increase of the lung cancer incidence from radon. Based on the above assumption, about 100 additional lung cancer deaths/year-million will result both from an increase in radionuclide concentrations in indoor air and a concomitant rise in effectiveness of radiation to cause cancer with higher exposure levels. Possibilities to reduce indoor radon levels in existing buildings and costs involved are discussed. (Auth.)

    2010-11-01

    Using detailed sociological and public health qualitative interview data, we demonstrate that energy poverty is more pervasive, and results in a greater energy burden for low-income tenants, than many policymakers would assume. This is due in part to a lack of funding, policy non-coordination, and a lack of understanding of the social and economic benefits of energy conservation, energy education, and flexible utility billing policies. Examining LIHEAP, weatherization, utility, and housing assistance policies, we suggest that a coordinated, regional approach to home energy and housing policy that integrates programs in each area will provide a more coherent policy solution.

    Frumuşanu, G.; Afteni, C.; Badea, N.; Epureanu, A.

    2017-08-01

    EU Directive 92/75/EC established for the first time an energy consumption labelling scheme, further implemented by several other directives. As consequence, nowadays many products (e.g. home appliances, tyres, light bulbs, houses) have an EU Energy Label when offered for sale or rent. Several energy consumption models of manufacturing equipments have been also developed. This paper proposes an energy efficiency - based classification of the manufacturing workstation, aiming to characterize its energetic behaviour. The concept of energy efficiency of the manufacturing workstation is defined. On this base, a classification methodology has been developed. It refers to specific criteria and their evaluation modalities, together to the definition & delimitation of energy efficiency classes. The energy class position is defined after the amount of energy needed by the workstation in the middle point of its operating domain, while its extension is determined by the value of the first coefficient from the Taylor series that approximates the dependence between the energy consume and the chosen parameter of the working regime. The main domain of interest for this classification looks to be the optimization of the manufacturing activities planning and programming. A case-study regarding an actual lathe classification from energy efficiency point of view, based on two different approaches (analytical and numerical) is also included.

  5. Energy efficiency in industry and transportation

    Ruscoe, J.

    1990-01-01

    The discussion of energy issues has changed since the 1970s as improvements have been made in energy efficiency. The present capacity for surplus energy production in economically advanced countries reflects a decrease in energy requirements as well as new production sources. At the same time, the energy crisis can be seen as having discouraged improvements in energy efficiency because of its negative impact on growth. And the centrally planned economies remain highly inefficient energy users. Economic growth encourages the use of new technologies which are likely to be less energy-intensive than those they replace. Permanent gains in energy efficiency are derived from structural changes in the economy and from the introduction of energy-efficient technologies. This article addresses the prospect of increased energy conservation, particularly in industry (the end-use which consumes the most energy) and transportation. Although investments in projects to promote energy conservation are more cost-effective and environment-friendly than investments in energy supply, there is still widespread support for the latter. Developing countries naturally give preference to quantitative growth, with an increasing consumption of energy, but in these countries, too, more efficient use of energy could greatly reduce demand. The policies of international development agencies which still favour increasing energy supply over conservation need to change. Awareness of the need to reduce energy demand is, however, growing worldwide. (author)

    By using our natural resources, and through inefficient use of energy, we produce much waste that can be recycled as a useful resource, which further contributes to climate change. This study aims to address energy effective bioclimatic architecture principles, by which we can achieve a potential energy savings, estimated at thirty-three per cent, mainly through environmentally affordable reconstruction, resulting in low negative impact on the environment. The study presented in this paper investigated the Ulpiana neighbourhood of Prishtina City, focusing on urban design challenges, energy efficiency and air pollution issues. The research methods consist of empirical observations through the urban spatial area using a comparative method, in order to receive clearer data and information research is conducted within Ulpiana's urban blocks, shapes of architectural structures, with the objective focusing on bioclimatic features in terms of the morphology and microclimate of Ulpiana. Energy supply plays a key role in the economic development of any country, hence, bioclimatic design principles for sustainable architecture and energy efficiency, present an evolutive integrated strategy for achieving efficiency and healthier conditions for Kosovar communities. Conceptual findings indicate that with the integrated design strategy: energy efficiency, and passive bioclimatic principles will result in a bond of complex interrelation between nature, architecture, and community. The aim of this study is to promote structured organized actions to be taken in Prishtina, and Kosovo, which will result in improved energy efficiency in all sectors, and particularly in the residential housing sector.

    Russia is sometimes referred to as 'the Saudi Arabia of energy efficiency'; its vast potential to reduce energy consumption can be considered a significant 'energy reserve'. Russia, recognising the benefits of more efficient use of energy, is taking measures to exploit this potential. The president has set the goal to reduce energy intensity by 40% between 2007 and 2020. In the past few years, the IEA has worked closely with Russian authorities to support the development of energy efficiency indicators in Russia, critical to an effective implementation and monitoring of Russia's ambitious energy intensity and efficiency goals. The key findings of the IEA work with Russia on developing energy efficiency indicators form the core of this report.

    We investigate the role of energy efficiency in rate-based emissions intensity standards, a particularly policy-relevant consideration given that the Environmental Protection Agency's Clean Power Plan allows crediting of electricity savings as a means of complying with state-specific emissions standards. We show that with perfectly inelastic energy services demand, crediting efficiency measures can recover the first-best allocation. However, when demand for energy services exhibits some elasticity, crediting energy efficiency can no longer recover first-best. While crediting removes the relative distortion between energy generation and energy efficiency, it distorts the absolute level of energy services. Building on these results, we derive the conditions determining the second-best intensity standard and crediting rule. Simulations calibrated to the electricity sector in Texas find that while some form of crediting is generally welfare-improving, the proposed one-for-one crediting of energy savings is unlikely to achieve efficient outcomes.

  11. House passes energy bill with one-step plant licensing

    International Nuclear Information System (INIS)

    Anon.

    1992-01-01

    The US House of Representatives which has traditionally been wary of measures that would allow nuclear power to expand, came down strongly on the side of nuclear when it approved a much-amended omnibus energy bill on May 27 by a vote of 381 to 37. The key for the nuclear industry is the presence in the bill (H.R. 776) of language on one-step power plant licensing that was taken directly from the Senate energy bill (S. 2166) that passed in February. This means that when the House and Senate work out a compromise version of the legislation, one-step licensing is almost certain to be carried through--and become law once the final bill is signed by President George Bush, which is expected later this year. The House's endorsement of nuclear power--both as it exists now, and as it could be with the introduction of new plant designs and an end to the long hiatus in plant orders by utilities--went beyond one-step licensing. Debate on the House floor prior to Memorial Day totally transformed the nuclear-related part of the energy bill. H.R. 776 was reported to the floor by the Rules Committee with language by the Interior and Insular Affairs Committee that would have created a nominal one-step system, with a full evidentiary hearing prior to plant construction but also allowing an intervenor who later presents new information on the plant to get another full evidentiary hearing after construction but before operation. This would effectively duplicate the two-step process that existed for all plants now in service, and which utilities no longer want to endure

    This comprehensive report for the Swiss Federal Office of Energy (SFOE) presents the results of a study made within the framework of the research programme on energy-economics fundamentals on how the energy efficiency of enterprises can be improved. The report first examines the present state of affairs in Swiss enterprises and looks into the interaction of energy efficiency and environmental management systems. ISO 14001 certification is discussed and examples are given of the responses of various enterprises to a survey concerning the role of energy efficiency in environmental management. Both hindrances and success factors for the embedding of energy-efficiency measures in environmental management activities are discussed and examples are given. Instruments available in Switzerland and from abroad that can be used to promote energy efficiency in enterprises are discussed. Four particular instruments are presented; guidelines and computer-based tools that help in the making of energy-relevant investment decisions, incentives to take part in an energy-benchmark system for small and medium-sized enterprises (SME), low-interest loans for investments in energy-efficiency for SMEs and the closer definition of 'continuous improvement' of energy efficiency within the framework of ISO 14001. The results of a survey amongst those involved are discussed. The report is concluded with recommendations for the implementation of the guidelines and for improvements in the integration of energy efficiency in environmental management systems

    This report outlines the lessons learned and sub-metered energy performance of an ultra low energy single family ranch home and duplex unit, called the Paradigm Pilot Project and presents the final design recommendations for a 153-unit net zero energy residential development called the Josephine Commons Project. Affordable housing development authorities throughout the United States continually struggle to find the most cost-effective pathway to provide quality, durable, and sustainable housing. The challenge for these authorities is to achieve the mission of delivering affordable housing at the lowest cost per square foot in environments that may be rural, urban, suburban, or within a designated redevelopment district. With the challenges the U.S. faces regarding energy, the environmental impacts of consumer use of fossil fuels and the increased focus on reducing greenhouse gas emissions, housing authorities are pursuing the goal of constructing affordable, energy efficient and sustainable housing at the lowest life-cycle cost of ownership. This report outlines the lessons learned and sub-metered energy performance of an ultra-low-energy single family ranch home and duplex unit, called the Paradigm Pilot Project and presents the final design recommendations for a 153-unit net zero energy residential development called the Josephine Commons Project. In addition to describing the results of the performance monitoring from the pilot project, this paper describes the recommended design process of (1) setting performance goals for energy efficiency and renewable energy on a life-cycle cost basis, (2) using an integrated, whole building design approach, and (3) incorporating systems-built housing, a green jobs training program, and renewable energy technologies into a replicable high performance, low-income housing project development model.

  15. Energy efficiency trends and policy in Slovenia

    International Nuclear Information System (INIS)

    Al-Mansour, Fouad

    2011-01-01

    The energy dependency of Slovenia is high (52.1%), but it is a little lower than the average energy dependency in the EU 27 (53.8%). Slovenia imports all its petroleum products and natural gas and partly coal and electricity. The energy intensity of Slovenia is higher by about 50% than the average in the EU 27. The target of the EU Directive on energy end-use efficiency and energy services adopted in 2006 is to achieve a 9% improvement of EE (energy efficiency) within the period 2008-2016. The new target of the EU climate and energy package '20-20-20 plan' is a 20% increase in EE by 2020. Since 1991 the Slovenian government has been supporting energy efficiency activities. The improvement of EE was one of the targets of strategic energy documents ReSROE (Resolution on the Strategy of Use and Supply of Energy in Slovenia from 1996 and ReNEP (Resolution on the National Energy Programme) from 2004 adopted by the Slovenian National Assembly (Parliament) in previous years. The Energy Act adopted in 1999 defines the objective of energy policy as giving priority to EE and utilization of renewable energy sources. The goals of the 'National Energy Action Plan 2008-2016 (NEEAP)' adopted by the Slovenian government in 2008 include a set of energy efficiency improvement instruments in the residential, industrial, transport and tertiary sectors. The target of the NEEAP is to save final energy in the 2008-2016 period, amounting to at least 4261 GWh or 9% of baseline consumption. The indicators of energy efficiency trends show considerable improvement in the period from 1998 to 2007. The improvement of EE was reached in all sectors: manufacturing, transport and households. The paper analyses the structure, trends of energy consumption and energy efficiency indicators by sectors of economic activity. A review of energy efficiency policy and measures is described in the paper.

    Industry contributes directly and indirectly (through consumed electricity) about 37% of the global greenhouse gas emissions, of which over 80% is from energy use. Total energy-related emissions, which were 9.9 GtCO2 in 2004, have grown by 65% since 1971. Even so, industry has almost continuously improved its energy efficiency over the past decades. In the near future, energy efficiency is potentially the most important and cost-effective means for mitigating greenhouse gas emissions from industry. This paper discusses the potential contribution of industrial energy efficiency technologies and policies to reduce energy use and greenhouse gas emissions to 2030.

    How should the lack of an efficient energy market affect the design of energy efficiency policies and their implementation? What the consequences of an inefficient energy market on end users’ behaviour? This article tries to give an answer to such questions, by considering the decision making of domestic users following a few fundamental concepts of behavioural economics. The mechanism of price formation in the market, with particular reference to the internal energy market in Europe, will be examined and we will show that price remains the inflexible attribute in making an energy choice. Then, some conclusions will be addressed to policy makers on how to overcome the barriers illustrated.

    Laquatra, J.; Chi, P.S.K.

    1996-09-01

    Recognizing the importance of energy conservation, under sponsorship of the US Department of Energy, Cornell University conducted a research and demonstration project entitled An Innovative Educational Program for Residential Energy Efficiency. The research project examined the amount of residential energy that can be saved through changes in behavior and practices of household members. To encourage these changes, a workshop was offered to randomly-selected households in New York State. Two surveys were administered to household participants (Survey 1 and Survey 2, Appendix A) and a control group; and a manual was developed to convey many easy but effective ways to make a house more energy efficient (see Residential Manual, Appendix B). Implementing methods of energy efficiency will help reduce this country`s dependence on foreign energy sources and will also reduce the amount of money that is lost on inefficient energy use. Because Cornell Cooperative Extension operates as a component of the land-grant university system throughout the US, the results of this research project have been used to develop a program that can be implemented by the Cooperative Extension Service nationwide. The specific goals and objectives for this project will be outlined, the population and sample for the research will be described, and the instruments utilized for the survey will be explained. A description of the workshop and manual will also be discussed. This report will end with a summary of the results from this project and any observed changes and/or recommendations for future surveys pertaining to energy efficiency.

    The Department of Energy funded the Alliance to Save Energy to promote the efficient use of energy under a multiyear cooperative agreement. This funding allowed the Alliance to be innovative and flexible in its program development, and to initiate and enhance projects it would otherwise not have been able to pursue. The program period was 1999 through 2004. The mission of the Alliance to Save Energy is to promote energy efficiency domestically and worldwide. The Alliance followed this mission by working closely with consumers, government, policy makers, and energy efficient product and service providers. The projects that were initiated by the Alliance included communication and consumer education, policy analysis and research, the promotion of interaction among the energy efficiency industry, and international energy efficiency programs. The funding from the Department of Energy allowed the Alliance to study new issues in energy efficiency, draw public attention to those issues, and create targeted programs, such as the Efficient Windows Collaborative or the Green Schools program, which now function on their own to promote energy efficiency in important areas.

    Highlights: • Comprehensive snapshot of regional energy system for decision makers. • Connecting regional sustainability targets and energy planning. • Involving local players in energy planning. - Abstract: Actions for increasing the renewable share in the energy supply and improving both production and end-use energy efficiency are often built into the regional level sustainability targets. Because of this, many local stakeholders such as local governments, energy producers and distributors, industry, and public and private sector operators require information on the current state and development aspects of the regional energy efficiency. The drawback is that an overall view on the focal energy system operators, their energy interests, and future energy service needs in the region is often not available for the stakeholders. To support the local energy planning and management of the regional energy services, an approach for increasing the regional energy efficiency is being introduced. The presented approach can be seen as a solid framework for gathering the required data for energy efficiency analysis and also evaluating the energy system development, planned improvement actions, and the required energy services at the region. This study defines the theoretical structure of the energy efficiency approach and the required steps for revealing such energy system improvement actions that support the regional energy plan. To demonstrate the use of the approach, a case study of a Finnish small-town of Lohja is presented. In the case example, possible actions linked to the regional energy targets were evaluated with energy efficiency analysis. The results of the case example are system specific, but the conducted study can be seen as a justified example of generating easily attainable and transparent information on the impacts of different improvement actions on the regional energy system.

  5. Towards a Sustainable Energy Balance: Progressive Efficiency and the Return of Energy Conservation

    We argue that a primary focus on energy efficiency may not be sufficient to slow (and ultimately reverse) the growth in total energy consumption and carbon emissions. Instead, policy makers need to return to an earlier emphasis on"conservation," with energy efficiency seen as a means rather than an end in itself. We briefly review the concept of"intensive" versus"extensive" variables (i.e., energy efficiency versus energy consumption), and why attention to both consumption and efficiency is essential for effective policy in a carbon- and oil-constrained world with increasingly brittle energy markets. To start, energy indicators and policy evaluation metrics need to reflect energy consumption as well as efficiency. We introduce the concept of"progressive efficiency," with the expected or required level of efficiency varying as a function of house size, appliance capacity, or more generally, the scale of energy services. We propose introducing progressive efficiency criteria first in consumer information programs (including appliance labeling categories) and then in voluntary rating and recognition programs such as ENERGY STAR. As acceptance grows, the concept could be extended to utility rebates, tax incentives, and ultimately to mandatory codes and standards. For these and other programs, incorporating criteria for consumption as well as efficiency offers a path for energy experts, policy-makers, and the public to begin building consensus on energy policies that recognize the limits of resources and global carrying-capacity. Ultimately, it is both necessary and, we believe, possible to manage energy consumption, not just efficiency in order to achieve a sustainable energy balance. Along the way, we may find it possible to shift expectations away from perpetual growth and toward satisfaction with sufficiency.

  6. Household energy and climate mitigation policies: Investigating energy practices in the housing sector

    One central aim of climate change mitigation in the European Union is to reduce energy consumption in the housing sector. In order to ensure effectiveness of policies targeting household energy conservation, it is important to investigate existing energy practices of different social groups. This article describes and explains energy practices in three leading states in environmental politics, technological innovation, and support for renewable energy production: Denmark, Austria, and the United Kingdom. Based on a longitudinal analysis of housing utility costs from the European Community Statistics on Income and Living Conditions we show that income plays a central role in households' energy practices. While high-income households have higher overall energy consumption, low-income groups spend a larger share of their income on utility costs. The variation of energy consumption across income groups is related to household characteristics, characteristics of the dwellings, and cross-national differences in the housing sector. - Highlights: • We explain energy practices in Denmark, Austria, and the United Kingdom. • We show that income plays a central role in households’ energy practices. • High-income households have higher overall energy consumption. • Low-income groups spend a larger share of their income on utility costs. • Consumption depends on the household, dwelling and the housing sector

    This is the national report for Norway in the EU/SAVE project ''Indicators for Energy Efficiency Monitoring and Target setting (ODYSSEE)''. The report deals with energy use and energy efficiency in Norway 1990-2000 (2001 for overall energy use). Final energy use per Gross Domestic Product (GDP) was reduced by approximately 1.9% pr year in the period 1990 to 2001. The energy efficiency improvement has been calculated to 0.6% pr year, while the role of structural changes has been 1.3% pr year. A detailed sector analysis has been done, applying Laspeyres indices to attribute changes in energy use to activity, structure or intensity (efficiency). Aggregating sectors, we have found a total efficiency improvement of approximately 11 TWh from 1990 to 2000. (author)

  8. Investing in Energy Efficiency. Removing the Barriers

    International Nuclear Information System (INIS)

    2004-01-01

    Investing in improving energy efficiency has the clear advantages of reducing energy costs, improving security of supply and mitigating the environmental impacts of energy use. And still, many viable opportunities for higher energy efficiency are not tapped because of the existence of numerous barriers to such investments. These lost opportunities imply costs to the individual energy consumers and to the society as a whole and they are particularly important in economies in transition. This report identifies various types of barriers for making energy efficiency investments (be they of legal, administrative, institutional or financial nature), mainly in buildings, district heating and efficient lighting. The role of various bodies and organisations for the facilitation of energy efficiency investments is analysed, from public authorities and regulators to banks and international financing institutions

    2017-06-01

    Full Text Available The solar energy is widely used around the world for electricity generation and heating systems in municipal services. But its use is complicated in the number of territories with uneven receipts of solar radiation on the earth’s surface and large number of cloudy days during a year. A hypothesis on the possibility of application of individual solar collectors for heating of houses in the number of cities of Russia has been tested. The existing designs of solar collectors and checking the possibility of their application in northern territories of Russia are investigated. The analysis was carried out taking into account features of relief and other climatic conditions of the Perm and Sverdlovsk regions. As the result of research, the basic recommended conditions for application of solar batteries in houses of the northern Russian cities have been resumed.

  12. Local government influence on energy conservation ambitions in existing housing sites-Plucking the low-hanging fruit?

    International Nuclear Information System (INIS)

    Hoppe, T.; Bressers, J.Th.A.; Lulofs, K.R.D.

    2011-01-01

    Greater energy efficiency can be achieved in existing dwellings thanks to longer lifecycles, slow replacement rates, and technical innovations. Many such dwellings are located in dense urban neighbourhoods, where urban renewal projects are undertaken. Local government can encourage the setting of ambitious goals as a stepping stone to realizing energy efficiency goals that achieve high levels of energy efficiency. The research question which this paper addresses is: to what degree do local governments influence ambitions to conserve energy in existing housing sites? To examine this issue, thirty-three sites in the Netherlands were studied using a quantitative analysis. The results show that collaboration between local authorities and local actors increases the level of ambition to conserve energy. However, local authorities intentionally selected sites with poor energy efficiency, so it would be easy to meet ambitious energy conservation targets. Collaboration between local authorities and local actors turns out to be the key factor in selecting those sites. Moreover, there is little sign of genuine ambition. This article contributes to the debate on energy conservation policies in local housing sites. The study provides starting points for systematic, empirical research into the realisation of energy conservation in existing housing, especially in large-scale refurbishment projects. - Research Highlights: → Local governments encourage the setting of goals to realize energy efficiency goals. → Local authorities intentionally select sites with poor initial energy efficiency performance. → Collaboration with local actors turns out to be a key factor in selecting those sites. →There is little sign of genuine ambition. → Starting points for empirical research into the realisation of energy conservation in housing.

It benefits from the combined support of the SAVE programme of the European Commission, of Ademe and of 15 national Efficiency Agencies within the European network of energy efficiency agencies. The objective of the project is to develop and maintain indicators that enable to review progress in energy efficiency and CO{sub 2} emissions abatement, by sector, end-use, etc.. for each country and the EU as a whole. To reach this objective, all data and indicators are stored in a common database called ODYSSEE that is regularly updated. A common methodology is used to produce comparative energy efficiency indicators from the database. The definitions presented in this document concern: 1) the general points (energy intensity, consumption, savings, efficiency, the unit consumption effect and index, the technological effect or savings, the substitution effect and the behavioural/management effect); 2) the macro-indicators (primary and final energy intensities at constant structure, at purchasing power parities, at reference economic structure); 3) industry (energy intensity of industry/manufacturing, of industry at constant structure and at reference structure, unit consumption of steel, cement etc.., process effect); 4) transports (energy intensity, unit consumption of vehicles, average specific consumption, test specific consumption, unit consumption, specific consumption, behavioural energy savings; 5) households and services (unit consumption, specific consumption, energy intensity of households, appliances); 6) transformations (apparent efficiency of energy sector or transformations, efficiency at constant fuel mix, efficiency of electricity sector).

    2010-01-01

    Using energy more efficiently is a key strategy for reducing global carbon dioxide emissions. Due to limitations on time and resources, actions must be focused on the efficiency measures which will deliver the largest gains. Current surveys of energy efficiency measures assess only known technology options developed in response to current economic and technical drivers. However, this ignores opportunities to deliver long-term efficiency gains from yet to be discovered options. In response, this paper aims to calculate the absolute potential for reducing energy demand by improving efficiency, by finding the efficiency limits for individual conversion devices and overlaying these onto the global network of energy flow. The potential efficiency gains for each conversion device are found by contrasting current energy demand with theoretical minimum energy requirements. Further insight is gained by categorising conversion losses according to the underlying loss mechanisms. The result estimates the overall efficiency of global energy conversion to be only 11 per cent; global demand for energy could be reduced by almost 90 per cent if all energy conversion devices were operated at their theoretical maximum efficiency.

    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)

    This report is meant to contribute to the preparation of National Energy Efficiency Action Plans (NEEAPs), which are tools supporting the implementation of energy efficiency improvement policies. The NEEAPs are considered one of the cornerstones of the Energy End-use Efficiency and Energy Services Directive. Previous publications from the NorthPass project report from studies of existing concepts and building standards in the participating countries, and analyses of main challenges in aiming to increase the market share of very low-energy houses. In this report a short overview of the current situation is given, and measures are proposed to support the implementation of the nearly Zero-Energy Building level, as described in the recast of the Energy Performance of Building Directive. Necessary steps towards a successful implementation will vary within the participating countries; involving technological, financial and policy implications in various degrees. The eight North European countries, participating in the NorthPass project, have similarities and differences. The four Nordic countries have several similarities regarding market penetration of very low-energy houses, as well as activities implemented by the authorities. Poland and the Baltic States have similarities in terms of market situation which is different from the Nordic countries. In the Nordic countries, the path towards the EU 2020 targets has, to a large extent, been chosen, focusing on step by step tightening of building codes, financial incentives and training of actors in the building sector. A discussion is going on about how to affect changes in customers' preferences, which would lead to a growing demand for very low-energy residential buildings. The situation in Poland and the Baltic countries is more problematic, as only few very low energy houses have been built so far. However, a growing interest in energy savings seems to arise, as the energy consumption is considerably high and the

    Energy consumption remains the key factor for the optimisation of the performance of membrane bioreactors (MBRs). This paper presents the results of the detailed energy audits of six full-scale MBRs operated by Suez Environnement in France, Spain and the USA based on on-site energy measurement and analysis of plant operation parameters and treatment performance. Specific energy consumption is compared for two different MBR configurations (flat sheet and hollow fibre membranes) and for plants with different design, loads and operation parameters. The aim of this project was to understand how the energy is consumed in MBR facilities and under which operating conditions, in order to finally provide guidelines and recommended practices for optimisation of MBR operation and design to reduce energy consumption and environmental impacts.

  12. Measures for energy efficiency improvement of buildings

    Directory of Open Access Journals (Sweden)

    Full Text Available The increase in energy consumption in buildings causes the need to propose energy efficiency improvement measures. Urban planning in accordance with micro location conditions can lead to energy consumption reduction in buildings through the passive solar design. While satisfying the thermal comfort to the user space purpose, energy efficiency can be achieved by optimizing the architectural and construction parameters such as shape of the building, envelope structure and the percentage of glazing. The improvement of the proposed measures, including the use of renewable energy sources, can meet requirements of Directive 2010/31 / EU of 'nearly zero energy buildings'.

  13. Energy Efficiency Policy and Carbon Pricing

    2011-07-01

    The main message of this paper is that while carbon pricing is a prerequisite for least-cost carbon mitigation strategies, carbon pricing is not enough to overcome all the barriers to cost-effective energy efficiency actions. Energy efficiency policy should be designed carefully for each sector to ensure optimal outcomes for a combination of economic, social and climate change goals. This paper aims to examine the justification for specific energy efficiency policies in economies with carbon pricing in place. The paper begins with an inventory of existing market failures that attempt to explain the limited uptake of energy efficiency. These market failures are investigated to see which can be overcome by carbon pricing in two subsectors -- electricity use in residential appliances and heating energy use in buildings. This analysis finds that carbon pricing addresses energy efficiency market failures such as externalities and imperfect energy markets. However, several market and behavioural failures in the two subsectors are identified that appear not to be addressed by carbon pricing. These include: imperfect information; principal-agent problems; and behavioural failures. In this analysis, the policies that address these market failures are identified as complementary to carbon pricing and their level of interaction with carbon pricing policies is relatively positive. These policies should be implemented when they can improve energy efficiency effectively and efficiently (and achieve other national goals such as improving socio-economic efficiency).

    2010-01-29

    This paper reviews the relationship between energy efficiency and demand response and discusses approaches and barriers to coordinating energy efficiency and demand response. The paper is intended to support the 10 implementation goals of the National Action Plan for Energy Efficiency's Vision to achieve all cost-effective energy efficiency by 2025. Improving energy efficiency in our homes, businesses, schools, governments, and industries - which consume more than 70 percent of the nation's natural gas and electricity - is one of the most constructive, cost-effective ways to address the challenges of high energy prices, energy security and independence, air pollution, and global climate change. While energy efficiency is an increasingly prominent component of efforts to supply affordable, reliable, secure, and clean electric power, demand response is becoming a valuable tool in utility and regional resource plans. The Federal Energy Regulatory Commission (FERC) estimated the contribution from existing U.S. demand response resources at about 41,000 megawatts (MW), about 5.8 percent of 2008 summer peak demand (FERC, 2008). Moreover, FERC recently estimated nationwide achievable demand response potential at 138,000 MW (14 percent of peak demand) by 2019 (FERC, 2009).2 A recent Electric Power Research Institute study estimates that 'the combination of demand response and energy efficiency programs has the potential to reduce non-coincident summer peak demand by 157 GW' by 2030, or 14-20 percent below projected levels (EPRI, 2009a). This paper supports the Action Plan's effort to coordinate energy efficiency and demand response programs to maximize value to customers.

    This study examines the possible evolution of Victorian energy markets over the 1998-2030 period from technical, economic and environmental perspectives. The focus is on the technical and economic potential over the study period for renewable energy and energy efficiency to increase their share of energy markets, through their economic competitiveness with the non-renewables of oil, gas and fossil fulled electricity. The study identifies a range of energy options that have a lower impact on carbon dioxide emissions that current projections for the Victorian energy sector, together with the savings in energy, dollars and carbon dioxide emissions. In addition the macroeconomic implications of the energy paths are estimated. Specifically it examines a scenario (R-efficient renewable) where energy efficiency and renewable energy sources realise their estimated economic potential to displace non-renewable energy over the 1988-2030 period. In addition, a scenario (T-Toronto) is examined where energy markets are pushed somewhat harder, but again on an economic basis, so that what is called the Toronto target of reducing 1988 carbon dioxide (CO 2 ) emissions by 20 per cent by 2005 is attained. It is concluded that over the next forty years there is substantial economic potential in Victoria for significant gains from energy efficiency in all sectors - residential, commercial, industrial and transport - and contributions from renewable energy both in those sectors and in electricity generations. 7 figs., 5 tabs

    1991-01-01

    Despite its huge population of about 100 million people, Nigeria consumes a relatively small share of the world's energy. GDP per capita equaled about US$ 800 in 1985. Agriculture accounts for the largest portion of GDP, at around 40%, followed by services with 31%, industry with 25% and transport with 4$. Unlike most other African nations, Nigeria has abundant energy sources. Recent estimates assumed that Nigeria has about 16 billion barrels of oil, 30 billion barrels of oil equivalent (boe) of gas and 3 billion boe of coal. The results of two long-term energy use and carbon emissions scenarios for Nigeria indicate that between 1985 and 2025, Nigeria's energy consumption will rise substantially as both population and economic growth rates soar. While biomass consumption drops markedly over the observed time period, gas and oil consumption witness significant increases. Coal and solar power also account for increasing shares of Nigeria's energy supply in the coming four decades. Hydro's share in energy use remains stable

    MENSA, a detailed model of Australia's energy system suggests that policies for overcoming information barriers to energy efficient investment may contribute to cost effectively reducing greenhouse gases by as much as 6 million tonnes in residential and transport sectors by 2000. The model also indicates that energy efficiency policies in these and other parts of the energy system would be insufficient to achieve a pro-rata of greenhouse gas reductions required to stabilize year 2000 emissions at 1990 levels. One cost effective policy involving the early scrapping of existing less fuel efficient motors is reviewed. 2 tabs., 1 fig., refs

    Giacone, E.; Mancò, S.

    2012-01-01

    Although the meaning of energy efficiency is clear, different definitions exist and important issues relating to its implementation still need to be addressed. It is now recognised that complicating factors – such as complex industrial sites and energy flows, multiple products and fuels, and the influence of production rate on energy efficiency – render it necessary to adopt a structured framework to define and measure energy efficiency more precisely. In this paper, a methodology is proposed to build such a framework. The whole energy system of a site is represented using a single matrix equation, which expresses the relationship between imported energies and energy drivers. The elements of the matrix are the specific energy consumptions of each single process. Mathematical process modelling, through statistical analysis of energy consumption data, is used to quantify the specific energy consumption as a function of the output. The results of this structured approach are relevant for energy benchmarking, budgeting and targeting purposes. Furthermore, this approach is suitable for implementation in an energy management system standard (e.g. EN 16001, ISO 50001) or LCA standard (e.g. ISO 14044). Glass and cast iron melting processes are presented in order to illustrate the application of the method. -- Highlights: ► A structured framework for energy efficiency in industrial processes is proposed. ► Two energy efficiency indicators are revised to take into account a variable output. ► The whole energy system of a factory can be represented by a single matrix equation. ► Mathematical modelling is used to characterise the energy consumption of a process. ► The results are relevant for energy benchmarking, budgeting and energy targeting.

    On behalf of Enova SF, Prognosesenteret AS and Entelligens AS carried out a potential and barrier study of energy efficiency of the Norwegian housing stock. The study made use of newer and known studies of the Norwegian housing stock, known and documented barriers to energy efficiency, and new and extensive studies of several topics which have only been partially or never explored before. Through unique analysis and a case-based approach, it revealed a real energy efficiency potential in Norwegian homes with known technology and revealed representativeness, relevance, strength and extent of the barriers that prevent that one can realize most of the technical energy efficiency potential in the Norwegian housing stock.

    Produced in cooperation with ADEME and Enerdata, this report presents and evaluates energy efficiency policies and trends in about 90 countries around the world. It reviews the impact of energy efficiency measures and highlights the trends and results of their implementation. Energy efficiency is ''a low hanging fruit'' on the ''energy tree'' which can help address a number of objectives at the same time and at a low or negative cost: security of supply, environmental impacts, competitiveness, balance of trade, investment requirements, social aspects and others. Despite its significant potential for energy savings, energy efficiency is still far from realising this potential. Why? There is no single answer to this question. A meaningful response requires major research and an analytical effort.

    Reducing fossil fuel consumption and increasing energy efficiency of agricultural systems may result in environmental and economic benefits. The aim of this study was to analyze dairy production systems from an energy perspective, to identify the main variables affecting energy efficiency and fossil energy consumption, through a model of inputs and outputs. The model included as inputs energy costs of food, labor, electricity, agrochemicals, fuels and machinery, and as outputs dairy and meat production. We analyzed a database of 30 dairy farms from southern Uruguay, from the Cooperative Nacional de Product ores de Leche (Conaprole), organized in three strata based on their dairy productivity per hectare. The fossil energy use was 2.40, 3.63 y 3.80 MJ.l-1 for productivity strata low, medium and high respectively (P<0.01). Energy efficiency averages were 1.40, 0.90 y 0.86 for the same strata (P<0.01). Fossil energy of agrochemicals and fuel accounted for more than 80% of the energy consumed in the three strata. The greater the percentage of concentrate in the diet, the lower energy efficiency (P<0.01). These results suggest the existence of a negative relationship between the intensification of dairy production and energy efficiency

    Energy efficiency has multiple benefits. It usually is a win-win option for all aspects of sustainability – environment, social objectives, and economy. We need to evaluate and communicate these multiple benefits – to citizens, companies, and policy-makers. Due to strong market barriers, effective governance and policy packages for energy efficiency are needed. Evaluation shows effective policy can achieve around 2% per year of additional energy savings.

    Successfully overcoming the barriers to higher energy efficiency requires development of policies designed for specific users and locations. Reform of energy pricing, which entails removing subsidies and beginning internalization of externalities, is critical to give technology producers and users proper signals for investment and management decisions. But while a rise in energy prices increases the amount of energy-efficiency improvement that is cost-effective, it does not remove other barriers that deter investment. Minimum efficiency standards or agreements can raise the market floor, and are important because they affect the entire market in the near-term. But they may not raise the celining very much, and do little to push the efficiency frontier. To accomplish these goals, incentives and other market-development strategies are needed. Utility programs in particular can play a key role in pushing energy efficiency beyond the level where users are likely to invest on their own. Policies, programs, and pricing should complement one another. Pricing reform alone will not overcome the many entrenched barriers to higher energy efficiency, but trying to accelerate energy efficiency improvement without addressing energy pricing problems will lead to limited success. Whether tagerting new equipment or management of existing systems, policies must reflect a thorough understanding of the particular system and an awareness of the motivations of the actors. 25 refs

    The report is prepared in relation to the project ''demonstration of energy consumption and indoor climate in 10 Danish passive houses'' which was carried out from 2008 to 2012 in the Comfort Houses. The report presents the achieved results based on measurements of indoor climate and energy consumption, and it also suggests viable solutions for the future low-energy buildings. The Comfort House project was started in 2007 as a development project at the company Saint Gobain Isover A/S, who wanted to disseminate knowledge about low-energy buildings and the principles behind them. The present report mainly focuses on the results from the Comfort Houses, but it also includes references to other Danish experimental buildings and development projects. Furthermore, the analyses are supplemented with experiences from Swedish low-energy buildings found through literature reviews. The indoor climate analyses deal with the different physical parameters that impact the residents. The evaluation includes both thermal, atmospheric, daylight and acoustic climate. The energy consumption is evaluated together with some of the key parameters from the houses that are related to the energy consumption. Finally, the residents' behaviour impacting both energy consumption and indoor climate are analysed. (LN)

  17. The Modern Solar House: Architecture, Energy, and the Emergence of Environmentalism, 1938--1959

    Barber, Daniel A.

    This dissertation describes the active discourse regarding solar house heating in American architectural, engineering, political, economic, and corporate contexts from the eve of World War II until the late 1950s. Interweaving these multiple narratives, the aim of the project is threefold: to document this vital discourse, to place it in the context of the history of architecture, and to trace through it the emergence of a techno-cultural environmentalism. Experimentation in the solar house relied on the principles of modern architecture for both energy efficiency and claims to cultural relevance. A passive "solar house principle" was developed in the late 30s in the suburban houses of George Fred Keck that involved open plans and flexible roof lines, and emphasized volumetric design. Spurred by wartime concern over energy resource depletion, architectural interest in solar heating also engaged an engineering discourse; in particular, an experimental program at the Massachusetts Institute of Technology led to four solar houses and a codification of its technological parameters. Attention to the MIT projects at the UN and in the Truman and Eisenhower administrations placed the solar house as a central node in an emergent network exploring the problems and possibilities of a renewable resource economy. Further experimentation elaborated on connections between this architecturalengineering discourse and the technical assistance regimes of development assistance; here by MIT researcher Maria Telkes, who also collaborated, at different junctures, with the architects Eleanor Raymond and Aladar Olgyay. The solar house discourse was further developed as a cultural project in the 1958 competition to design a solar heated residence, "Living With the Sun," which coalesced the diverse formal tendencies of midcentury modernism to promote the solar house as an innovation in both lifestyle and policy. Though the examples described are not successful as either technological

    Energy is the fundamental driver of the economic growth in the todays society. It is an absolute prerequisite for the industrial development in the developed countries as well as for improving the quality of life and reducing the poverty in the developing world. It is expected that the energy demand in the developing countries will increase rapidly in the next decades, and will even exceed the level of consumption in the rich countries due to rising population and incomes. The burning of fossil fuel, however, inevitably leads to negative environmental impact, which no longer can be neglected

    Network planning is one of the management techniques used to plan and control the implementation of a project, which shows the relationship between activities. The objective of this research is to arrange network planning on house construction project on CV. XYZ and to know the role of network planning in increasing the efficiency of time so that can be obtained the optimal project completion period. This research uses descriptive method, where the data collected by direct observation to the company, interview, and literature study. The result of this research is optimal time planning in project work. Based on the results of the research, it can be concluded that the use of the both methods in scheduling of house construction project gives very significant effect on the completion time of the project. The company’s CPM (Critical Path Method) method can complete the project with 131 days, PERT (Program Evaluation Review and Technique) Method takes 136 days. Based on PERT calculation obtained Z = -0.66 or 0,2546 (from normal distribution table), and also obtained the value of probability or probability is 74,54%. This means that the possibility of house construction project activities can be completed on time is high enough. While without using both methods the project completion time takes 173 days. So using the CPM method, the company can save time up to 42 days and has time efficiency by using network planning.

    Multifamily deep energy retrofits (DERs) represent great potential for energy savings, while also providing valuable insights on research-generated efficiency measures, cost-effectiveness metrics, and risk factor strategies for the multifamily housing industry. This report describes the Bay Ridge project, a base scope retrofit with a goal of achieving 30% savings (relative to pre-retrofit), and a DER scope with a goal of 50% savings (relative to pre-retrofit). Findings from the short-term testing at Bay Ridge include air infiltration reductions of greater than 60% in the DER building; a hybrid heat pump system with a Savings to Investment Ratio (SIR) > 1 (relative to a high efficiency furnace) which also provides the resident with added incentive for energy savings; and duct leakage reductions of > 60% using an aerosolized duct sealing approach.

  12. Moving around efficiently: Energy and transportation

    Full Text Available Worldwide, transportation takes almost 20% of the total energy use, and more than half of the oil consumption. By far the largest part is used by cars powered by internal combustion engines. The reason is simple: oil and gasoline are ideal energy carriers for transportation, since their energy density is extremely high. However, in terms of energy efficiency the internal combustion engine has a poor performance: about 25% only. How does this compare with electric cars? What are the alternative transportation systems and their efficiencies anyway? In this lecture we will analyse the efficiency of various transport systems, using elementary physics principles. We will look at cars, buses, trains and TGVs, ships, aircraft and zeppelins. Also the efficiency of human powered vehicles will be considered. Special attention is given to future mobile energy carriers like hydrogen, batteries and super capacitors.

    Induced technical change is crucial for tackling the problem of timing in environmental policy. However, it is by no means obvious that the state has the ability to impose its will concerning technical change on the other relevant actors. Therefore, we conceptualize power in a non-linear model with social conflict and induced technical change. The model shows how economic growth, business cycles and innovation waves interact in the dynamics of energy efficiency. We assess three different ways of government control: energy taxes, energy and labor subsidies, and energy caps. Energy taxes help to select more energy efficient technologies. However, a successful selection of such technologies presupposes that they are available in the pool of technologies. As for energy subsidies, their existence helps to explain why in contemporary economies labor productivity grows faster than energy efficiency. With an energy cap, the social network of the relevant agents may be stabilized via social norms. It seems plausible that innovation waves comprise several business cycles and that such a wave is currently in the making. Proposals to postpone policies for improving energy efficiency increase the risk of energy inefficient lock-in effects. (Copyright (c) 1998 Elsevier Science B.V., Amsterdam. All rights reserved.)

    China is fueling its phenomenal economic growth with huge quantities of coal. The environmental consequences reach far beyond its borders--China is second only to the United States in greenhouse gas emissions. Expanding its supply of other energy sources, like nuclear power and imported oil, raises trade and security issues. Soaring electricity demand necessitates the construction of 40-70 GW of new capacity per year, creating sustained financing challenges. While daunting, the challenge of meeting China's energy needs presents a wealth of opportunities, particularly in meeting demand through improved energy efficiency and other clean energy technologies. The China Energy Group at the Lawrence Berkeley National Laboratory (LBNL) is committed to understanding these opportunities, and to exploring their implications for policy and business. We work collaboratively with energy researchers, suppliers, regulators, and consumers in China and elsewhere to: better understand the dynamics of energy use in China. Our Research Focus Encompasses Three Major Areas: Buildings, Industry, and Cross-Cutting Activities. Buildings--working to promote energy-efficient buildings and energy-efficient equipment used in buildings. Current work includes promoting the design and use of minimum energy efficiency standards and energy labeling for appliances, and assisting in the development and implementation of building codes for energy-efficient residential and commercial/public buildings. Past work has included a China Residential Energy Consumption Survey and a study of the health impacts of rural household energy use.

    The Korean government announced its plan to raise the previous reduction goal of greenhouse gas emission from buildings by 26.9% until 2020 on July 2015. Therefore, policies regarding efficiency in the building energy are implemented fast, but the level of building owners and market understanding is low in general, and the government service system which supports decision making for implementing low-energy buildings has not been provided yet. The purpose of this study is to present the design direction for establishing user customized building energy database to perform a role to provide autonomous ecosystem of low-energy buildings. In order to reduce energy consumption in buildings, it is necessary to carry out the energy performance analysis based on the characteristics of target building. By analysing about 20-thousand cases of the amount of housing energy consumption in Korea, this study suggested the real energy consumption pattern by building types. Also, the energy performance of a building could be determined by energy consumption, but previous building energy consumption analysis programs required expert knowledge and experience in program usage, so it was difficult for normal building users to use such programs. Therefore, a measure to provide proper default using the level of data which general users with no expert knowledge regarding building energy could enter easily was suggested in this study.

    Energy Technology Data Exchange (ETDEWEB)

    2001-11-01

    This thesis deals with energy-efficient windows in Swedish buildings. Parametric studies were performed in the dynamic energy simulation tool Derob-LTH in order to study the effects of window choices on energy use and indoor climate for both residential and office buildings. A steady-state program was used to evaluate two years of measurements of energy use and indoor temperatures of an energy-efficient row-house. Two behavioural studies regarding (1) daylight transmittance, view and room perception using super-insulated windows and (2) the satisfaction with the daylight environment and the use of shading devices in response to daylight/sunlight were conducted in full-scale laboratory environments exposed to the natural climate. Results show that as the energy-efficiency of buildings increase, window U-values must decrease in order not to increase the annual heating demand, since the heating season is shortened, and useful solar gains become smaller. For single-family houses with a window-to-floor area ratio of 15 % and insulated according the current Swedish building code, the U-values should thus on average be lower than 1.0 W/m{sup 2}K. For houses insulated according to 1960s standard, the U-value may on average be 1.6 W/m{sup 2}K. For colder climates (northern Sweden), the U-values should be somewhat lower, while slightly higher U-values can be tolerated in milder climates of south Sweden. Thermal comfort during winter is improved for energy-efficient windows. However, overheating problems exist for both super-insulated houses and highly glazed office buildings showing a need for very low U-values in combination with low g-values. Daylight experiments indicate that the use of two low-emittance coatings tints the transmitted daylight enough to be appreciated, and colours may be perceived as more drab and rooms more enclosed. A compromise between energy-efficiency and daylighting may be needed, and it is suggested that only one coating be used except when very

    Highlights: • Analytical tool was applied to estimate the energy efficiency indicator of energy intensive industries in Taiwan. • The carbon dioxide emission intensity in selected energy-intensive industries is also evaluated in this study. • The obtained energy efficiency indicator can serve as a base case for comparison to the other regions in the world. • This analysis results can serve as a benchmark for selected energy-intensive industries. - Abstract: Taiwan imports approximately 97.9% of its primary energy as rapid economic development has significantly increased energy and electricity demands. Increased energy efficiency is necessary for industry to comply with energy-efficiency indicators and benchmarking. Benchmarking is applied in this work as an analytical tool to estimate the energy-efficiency indicators of major energy-intensive industries in Taiwan and then compare them to other regions of the world. In addition, the carbon dioxide emission intensity in the iron and steel, chemical, cement, textile and pulp and paper industries are evaluated in this study. In the iron and steel industry, the energy improvement potential of blast furnace–basic oxygen furnace (BF–BOF) based on BPT (best practice technology) is about 28%. Between 2007 and 2011, the average specific energy consumption (SEC) of styrene monomer (SM), purified terephthalic acid (PTA) and low-density polyethylene (LDPE) was 9.6 GJ/ton, 5.3 GJ/ton and 9.1 GJ/ton, respectively. The energy efficiency of pulping would be improved by 33% if BAT (best available technology) were applied. The analysis results can serve as a benchmark for these industries and as a base case for stimulating changes aimed at more efficient energy utilization

    This study asks what is the ‘best’ way to measure urban energy efficiency. There has been recent interest in identifying efficient cities so that best practices can be shared, a process known as benchmarking. Previous studies have used relatively simple metrics that provide limited insight on the complexity of urban energy efficiency and arguably fail to provide a ‘fair’ measure of urban performance. Using a data set of 198 urban UK local administrative units, three methods are compared: ratio measures, regression residuals, and data envelopment analysis. The results show that each method has its own strengths and weaknesses regarding the ease of interpretation, ability to identify outliers and provide consistent rankings. Efficient areas are diverse but are notably found in low income areas of large conurbations such as London, whereas industrial areas are consistently ranked as inefficient. The results highlight the shortcomings of the underlying production-based energy accounts. Ideally urban energy efficiency benchmarks would be built on consumption-based accounts, but interim recommendations are made regarding the use of efficiency measures that improve upon current practice and facilitate wider conversations about what it means for a specific city to be energy-efficient within an interconnected economy. - Highlights: • Benchmarking is a potentially valuable method for improving urban energy performance. • Three different measures of urban energy efficiency are presented for UK cities. • Most efficient areas are diverse but include low-income areas of large conurbations. • Least efficient areas perform industrial activities of national importance. • Improve current practice with grouped per capita metrics or regression residuals

    We review the relationship between energy efficiency improvement measures and productivity in industry. We review over 70 industrial case studies from widely available published databases, followed by an analysis of the representation of productivity benefits in energy modeling. We propose a method to include productivity benefits in the economic assessment of the potential for energy efficiency improvement. The case-study review suggests that energy efficiency investments can provide a significant boost to overall productivity within industry. If this relationship holds, the description of energy-efficient technologies as opportunities for larger productivity improvements has significant implications for conventional economic assessments. The paper explores the implications this change in perspective on the evaluation of energy-efficient technologies for a study of the iron and steel industry in the US. This examination shows that including productivity benefits explicitly in the modeling parameters would double the cost-effective potential for energy efficiency improvement, compared to an analysis excluding those benefits. We provide suggestions for future research in this important area.

    We present theoretical performance estimates for nanotube optoelectronic devices under bias. Current-voltage characteristics of illuminated nanotube p-n junctions are calculated using a self-consistent nonequilibrium Green's function approach. Energy conversion rates reaching tens of percent are predicted for incident photon energies near the band gap energy. In addition, the energy conversion rate increases as the diameter of the nanotube is reduced, even though the quantum efficiency shows little dependence on nanotube radius. These results indicate that the quantum efficiency is not a limiting factor for use of nanotubes in optoelectronics.

    In 2004 Italy introduced an obligation for electricity and gas distribution companies to reach specific objectives regarding the improvement of energy efficiency in final energy consumption. The scope of the provision is to promote investments in energy efficiency in order to meet the greenhouse gases reduction target set by the Kyoto protocol. The adoption of binding targets of energy efficiency will also lead to the development of an energy services market, modifying the traditional relation between energy dealers and final consumers, thus leading to a more efficient use of the available resources. Similar mechanisms have already been applied in other European countries (as France and United Kingdom) and will be likely introduced in other countries with the implementation of European Directive on energy end-use efficiency and energy services. This paper describes and analyzes both the measures adopted in Italy and the results obtained after the first year of operation of the mechanism. The paper is divided in six different sections. In the first part we highlight the main problems related to the development of system based on tradable white certificates. In the second part we provide a brief description of the Italian regulatory context. In the third part there is an economic analysis of investments in energy efficiency. The fourth part considers the different options that distribution companies face in order to reach the energy efficiency targets. The fifth part shows the results obtained after the first year of operation of the mechanism. Finally, we propose some possible modifications to the scheme adopted in Italy considering the results obtained and the alternative solutions already applied in France and United Kingdom [it

    In the wake of the greenhouse effect and global energy crisis, finding sources of clean, alternative energy and developing everyday life applications have become urgent tasks. This study proposes the development of an "autonomous house" emphasizing the use of modern green energy technology to reduce environmental load, achieve energy autonomy and use energy intelligently in order to create a sustainable, comfortable living environment. The houses' two attributes are: (1) a self-sufficient energy cycle and (2) autonomous energy control to maintain environmental comfort. The autonomous house thus combines energy-conserving, carbon emission-reducing passive design with active elements needed to maintain a comfortable environment.

    In order to reduce the ecological impact of resource exploitation, the EU calls for sustainable options to increase the efficiency and productivity of the utilization of natural resources. This target can only be achieved by considering resource recovery from waste comprehensively. However, waste management measures have to be investigated critically and all aspects of substance-related recycling and energy recovery have to be carefully balanced. This article compares recovery methods for selected waste fractions with regard to their energy efficiency. Whether material recycling or energy recovery is the most energy efficient solution, is a question of particular relevance with regard to the following waste fractions: paper and cardboard, plastics and biowaste and also indirectly metals. For the described material categories material recycling has advantages compared to energy recovery. In accordance with the improved energy efficiency of substance opposed to energy recovery, substance-related recycling causes lower emissions of green house gases. For the fractions paper and cardboard, plastics, biowaste and metals it becomes apparent, that intensification of the separate collection systems in combination with a more intensive use of sorting technologies can increase the extent of material recycling. Collection and sorting systems must be coordinated. The objective of the overall system must be to achieve an optimum of the highest possible recovery rates in combination with a high quality of recyclables. The energy efficiency of substance related recycling of biowaste can be increased by intensifying the use of anaerobic technologies. In order to increase the energy efficiency of the overall system, the energy efficiencies of energy recovery plants must be increased so that the waste unsuitable for substance recycling is recycled or treated with the highest possible energy yield.

    Here we present the main elements of the annual report on energy efficiency 2015. The results indicate that, thanks to national policies for energy efficiency, Italy saved over 7.5 million tons of oil equivalent per year in the period 2005-2013. Compared to the National Plan for Energy Efficiency 2014, the report shows that the 2020 objectives have already been achieved for more than 20%, with residential (35.7% of the target) and industry (26.6%) among the sectors that contributed most to this result. Substantial savings could result from the agribusiness sector through the dissemination of efficient technologies in the logistics and large retail chains. A key role lies with the banks: 86% of banks has developed products dedicated to efficiency, necessitating guidelines for replicability of projects, and audit and rating to assess their quality [it

    An examination is made of the incentives which influence the decisions by local governments to adopt energy-efficiency programs, either unilaterally or in partnership with the Federal government. It is found that there is significant potential for improved energy efficiency in urban residential, commercial, and industrial buildings and that exploiting these opportunities is in the interest of both Federal and local governments. Unless there is a unique combination of strong local leadership, a tradition of resource management, and external energy shocks, communities are unlikely to realize this potential. Conflicting demands, traditional perceptions, and lack of funding pose a major barrier to a strong unilateral commitment by local governments. A Federal-local partnership built upon and complementary to existing efforts in areas such as housing, social welfare, and economic development offers an excellent opportunity to realize the inherent potential of local energy-efficiency programs. At the local level, energy is not perceived as an isolated issue, but one which is part of a number of problems arising from the continuing increase in energy prices.

    Rural buildings in China now account for more than half of China's total building energy use. Forty percent of the floorspace in China is in rural villages and towns. Most of these buildings are very energy inefficient, and may struggle to provide for basic needs. They are cold in the winter, and often experience indoor air pollution from fuel use. The Chinese government plans to adopt a voluntary building energy code, or design standard, for rural homes. The goal is to build on China's success with codes in urban areas to improve efficiency and comfort in rural homes. The Chinese government recognizes rural buildings represent a major opportunity for improving national building energy efficiency. The challenges of rural China are also greater than those of urban areas in many ways because of the limited local capacity and low income levels. The Chinese government wants to expand on new programs to subsidize energy efficiency improvements in rural homes to build capacity for larger-scale improvement. This article summarizes the trends and status of rural building energy use in China. It then provides an overview of the new rural building design standard, and describes options and issues to move forward with implementation. - Highlights: • Building energy use is larger in rural China than in cities. • Rural buildings are very energy intensive, and energy use is growing with incomes. • A new design standard aims to help rural communities build more efficiently. • Important challenges remain with implementation
