    The Riga Technical University Institute of Energy Systems and Environment, in cooperation with three Latvian companies, is implementing the project "Compact solar and pellet module" financed by the European Union. Within the framework of this project a combisystem will be installed in the Grandeg Ltd modular pellet boiler house. The solar combisystem will provide domestic hot water and space heating load for an apartment building in Sigulda. Due to the limited amount of space in the modular boiler house, optimal decisions should be made on the technical parameters of the system, including the volume of the heat storage tank and the surface area of solar collectors. Every alternative has both advantages and disadvantages. Economic factors of various alternatives are analyzed.

    Air flow, air leakage measurements and numerical simulations were made on a 13-story apartment building to characterize the ventilation rates for the individual apartments. Parametric simulations were performed for specific conditions, e.g., height, orientation, outside temperature and wind speed. Our analysis of the air flow simulations suggest that the ventilation to the individual units varies considerably. With the mechanical ventilation system disabled and no wind, units at the lower level of the building have adequate ventilation only on days with high temperature differences, while units on higher floors have no ventilation at all. Units facing the windward side will be over-ventilated when the building experiences wind directions between west and north. At the same time, leeward apartments did not experience any fresh air-because, in these cases, air flows enter the apartments from the corridor and exit through the exhaust shafts and the cracks in the facade. Even with the mechanical ventilation system operating, we found wide variation in the air flows to the individual apartments. In addition to the specific case presented here, these findings have more general implications for energy retrofits and health and comfort of occupants in high-rise apartment buildings.

    We compiled and analyzed available data concerning indoor-outdoor air leakage rates and building leakiness parameters for commercial buildings and apartments. We analyzed the data, and reviewed the related literature, to determine the current state of knowledge of the statistical distribution of air exchange rates and related parameters for California buildings, and to identify significant gaps in the current knowledge and data. Very few data were found from California buildings, so we compiled data from other states and some other countries. Even when data from other developed countries were included, data were sparse and few conclusive statements were possible. Little systematic variation in building leakage with construction type, building activity type, height, size, or location within the u.s. was observed. Commercial buildings and apartments seem to be about twice as leaky as single-family houses, per unit of building envelope area. Although further work collecting and analyzing leakage data might be useful, we suggest that a more important issue may be the transport of pollutants between units in apartments and mixed-use buildings, an under-studied phenomenon that may expose occupants to high levels of pollutants such as tobacco smoke or dry cleaning fumes.

    Full Text Available Circulation pumps are mechanical devices, which are used to create the overpressure required for the transportation of a heat-transfer medium in heating technology as well as in other related technologies. In a circulation pump the mechanical energy generated by the drive machine – an electric motor is transformed to hydraulic energy, which consists of kinetic and static energy. In the pipeline of a heating system circulation pumps represent a source of hydraulic energy (positive differential pressure, which is consumed to transport the heat-transfer medium. During the flow, the heat-transfer medium puts up resistance to the so-called passive resistors, which consist of pressure losses from friction in the pipes and pressure losses due to local resistance. In this article the authors analyze the effect of a circulation pump on the operating costs in an apartment building. Different types of circulating pumps, ranging from the most unfavorable to the optimal, were selected.

  12. Analysis of energy economic renovation for historic wooden apartment buildings in cold climates

    International Nuclear Information System (INIS)

    Highlights: • Energy saving potential in historic wooden apartment buildings is up to 63%. • In historic wooden apartment buildings an economically viable energy saving level is 50%. • The largest energy saving potential lies in heat source and building service systems. • Of the building structures, insulation of the external wall has the highest potential. • New heating and ventilation systems must be installed to fulfill regulations limits. - Abstract: Buildings represent the largest sector of primary energy consumption and play a major role in saving energy and reducing greenhouse gas emissions. Our analysis of energy consumption and potential energy savings is based on field measurements, computer simulations and economic calculations. The average primary energy consumption (PE) of wooden apartment buildings was 331 kW h/(m2 a) 83% higher than the limit 180 kW h/(m2 a) set in national regulations for apartment buildings subject to major renovation. The studied buildings represent a high potential for energy savings. The renovation packages were compiled using different insulation measures, HVAC solutions and energy sources to achieve a 20–65% reduction of primary energy. For historic buildings, the renovation solutions that concentrate on the building envelope can be problematic due to the need to preserve cultural and architectural values. Our calculation results indicate that the cost optimal PE level is around 250 kW h/(m2 a) and the point at which renovation packages recover expenses is around a PE level of 170 kW h/(m2 a). In terms of the architectural appearance the point at which renovation packages recover expenses is around a PE level of 210 kW h/(m2 a). We propose to set a different PE limit for historic wooden apartment buildings with an architectural appearance worth preserving

  13. Extra cost analyses of two apartment buildings for achieving nearly zero and low energy buildings

    International Nuclear Information System (INIS)

    The nZEB (nearly zero energy building) requirements taking effect in 2021 have induced the interest about additional cost and technical solutions amongst real-estate developers, construction companies, architects and engineers. The objectives of this study are twofold, first to determine the cost-optimal energy efficiency level for two lately built apartment buildings in a cold climate of Estonia, and secondly, which are the proper measures to achieve low energy and nZEB requirement levels. The influence of high-efficiency external walls, roofs, windows, ventilation units and solar collectors on energy use and construction costs were studied by using multi-stage methodology for reducing the number of combinations. The results show that since 2010 the cost optimal primary energy level has shifted from 145 kWh/m2 to 110 kWh/m2, but achieving nZEB level of 100 kWh/m2 still requires relatively high additional investments. With initial measures, nZEB requirements were not fulfilled in the studied cases, but the solutions close to nZEB required extra investment of 65 €/m2 i.e. 4–7% compared to the actual buildings. Low energy building level needed additional investments up to 2%. In both case studies remarkably better energy efficiency level could have been achieved with lower construction costs. - Highlights: • EU's nZEB requirements have induced the interest for economic quantification. • Since 2010 the cost optimal primary energy level has shifted from 145 kWh/m2 to 110 kWh/m2. • Achieving nZEB level of 100 kWh/m2 still requires relatively high additional investments. • In both studied cases remarkably better energy efficiency level could have been achieved with lower investments

    Understanding infiltration of outdoor pollutants was an integral part of the Brooklyn Traffic Real-Time Ambient Pollutant Penetration and Environmental Dispersion (B-TRAPPED) study. For this reason, the structural and air exchange properties of the three-story row house in Brooklyn, NY, USA, that was used in the B-TRAPPED experiments were fully characterized. Factors investigated included representativeness of the construction and impact of building design features on the natural ventilation and infiltration of outdoor aerosol. Both blower door and perfluorocarbon tracer (PFT) air exchange rate (AER) experiments showed that the ventilation rates of the building were quite typical of similar structures in the New York City (NYC) metropolitan area. Indoor/outdoor (I/O) aerosol count ratios by particle size were comparable to a similar vintage naturally ventilated building in Boston, MA, USA. I/O ratio analyses were consistent with literature findings and showed I/O ratios ranging from 0.310 to 0.601, varying across particle sizes (from 0.3 to 5.0 [corrected] mum) and between first and second floor apartments. An effort to apply the rebound method of Thatcher et al. (Aerosol Sci. Technol., 2003, 37, 847-864) in determining aerosol infiltration rates proved unsuccessful due to unexpectedly long (>60 min) equilibration times after the filtration period. Uninsulated interior wall renovations in the study house created a cavity that resulted in a large intermediate dead volume (for infiltration) that apparently could not be accommodated by a simple infiltration model. Simple two-compartment models evidently have finite application limitations for even modestly complex settings. PMID:20024015

    Full Text Available Bed bug (Cimex lectularius L. infestations are currently controlled by a variety of non-chemical and chemical methods. There have been few studies on the comparative effectiveness of these control techniques. We evaluated three bed bug management strategies in an apartment building: (1 non-chemical methods only (n = 9; (2 insecticides only (n = 6; and (3 integrated pest management including both non-chemical methods and insecticides (n = 9. The apartments were one-bedroom units occupied by seniors or people with disabilities. Bed bug numbers in each apartment were determined by visual inspection and/or installing intercepting devices under bed and sofa legs. The median (min, max bed bug counts in the non-chemical methods only, insecticides only, and integrated pest management (IPM treatment were: 4 (1, 57, 19 (1, 250, and 14 (1, 219, respectively prior to the treatments. The apartments were retreated if found necessary during biweekly to monthly inspections. After 10 weeks, bed bugs were found to be eliminated from 67, 33, and 44% of the apartments in the three treatment groups, respectively. The final (after 10 weeks median (min, max bed bug counts in the non-chemical methods only, insecticides only, and IPM treatment were: 0 (0, 134, 11.5 (0, 58, and 1 (0, 38, respectively. There were no significant differences in the speed of bed bug count reduction or the final bed bug counts. Lack of resident cooperation partially contributed to the failure in eliminating bed bugs from some of the apartments. Results of this study suggest that non-chemical methods can effectively eliminate bed bugs in lightly infested apartments.

    Full Text Available During the last ten years, the growth of apartment buildings in Surabaya has encountered the bitter experience of global warming, resource depletion, energy scarcity, and other environmental impacts. We cannot avoid them, but we can minimize the negative impacts of global warming. The green building concept is one of the methods to minimize the environmental impact. It takes into account principles of sustainable development in planning, construction, operation, and maintenance. Greenship Rating Tools is used to evaluate and calculate green achievements, prior to green building certification. The aim of this research is to represent the perceptions of contractors and consultants toward application of Greenship Rating Tools on apartment buildings in Surabaya. Based on the data obtained from a questionnaires survey carried out to 41 respondents, the mean value ranking method is used to evaluate the main factors of Greenship. These factors are Appropriate Site Development, Energy Efficiency and Conservation, Water Conservation, Material Resource and Cycle, Indoor Health and Comfort, and Building Environmental Management. In general, the results of this research show that there are a number of differences between perceptions of contractors and consultants toward application of Greenship Rating Tools on apartment buildings in Surabaya. According to the contractors’ perception, Visual Comfort is a factor that would easily to be applied, whilst consultants’ is Landscape. On the other hand, there are factors that would difficult to be applied. Based on contractors’ perceptiom is Climate Change, while consultants’ perception is Renewal Energy. In summary, Greenship Rating Tools can be applied on contractors’ and consultants’ perceptions, whilst there are some variables which can not be applied.

  1. Influence of windows on the energy balance of apartment buildings in Amman

    International Nuclear Information System (INIS)

    The influence of windows on the energy balance of apartment buildings in Amman is investigated by using self developed simulation software (SDS) based on the ASHRAE tables for solar heat gain calculation and coaling load factor for latitude 32 deg., where Amman city is located. The calculations of energy saving are made to find out the influence of windows on the energy balance of apartment buildings in Amman. Also, the present investigation aimed to study the energy performance of windows of an apartment building in Amman in order to select the most energy efficient windows that can save more energy and reduce heating load in winter, the percentage of saving energy and saving fuel and money through time. Variations of type of glazing using eight types of glazing (clear glass, types A, B, C, D, E, F, and G) are made to find out the most appropriate type of glazing in each direction. Also the orientation of window is changeable in the main four directions (N, S, E and W). The area of glazing varies also in different orientation to find the influence of window area on the thermal balance of the building. The results show that if energy efficient windows are used, the flexibility of choosing the glazed area and orientation increases. It has been found that choosing a larger area facing south, east and west can save more energy and decrease heating costs in winter using certain types of glazing such as glass type A and clear glass, while decreasing the glazing area facing north can save money and energy. However, it has been found that the energy can be saved in the north direction if glass type B has been used. In the apartment building, it is found that certain combination of glazing is energy efficient than others. This combination consists of using large area of glass type A in the east, west and south direction, and glass type B in the north direction or reducing glazing area as possible in the north direction.

    Solar co-generation applied in buildings has the advantage of increasing the energy output per unit installed collector area. This paper investigates a centralized photovoltaic and hot-water collector system that can serve as a water pre-heating system for a multistorey apartment building in a warm climate region. Collectors are mounted on vertical facades. Electricity generated by the system is consumed by the circulation pumps and the water heaters. The facade integration, together with the heat and electricity co-generation, are features embedding both active and passive solar technology. A numerical model that analyzes its energy performance in an apartment building in Hong Kong is described. The study has been based on practical design requirements. It is estimated that, with the use of amorphous-silicon hybrid collectors which cover two-thirds of the west- and south-facing facades, the system is able to support one-third of the thermal energy required for water heating.

    The aim of this study was to provide an understanding of how residents in apartment buildings perceive and react to impact sounds coming from the upstairs neighbours' dwellings. Based on existing theoretical and empirical studies on environmental noise, a conceptual model was developed to explain relationships among noise annoyance and non-acoustic factors. The model was then tested using structural equation modelling with survey data from residents living in apartment buildings (N = 487). The findings showed that the conceptual model was consistent with other models developed for environmental noises. The results indicated that annoyance induced by floor impact noise was associated with perceived disturbance, coping, and self-reported health complaints. Noise sensitivity had a direct impact on perceived disturbance and an indirect impact on annoyance, and moderating variables affected the non-acoustic factors. Exposure to footstep noises increased the impact size of noise sensitivity to disturbance. Predictability, marital status, and house ownership were found to influence the relationship between attitudes towards authorities and coping. In addition, a negative attitude towards neighbours (i.e., the noise source) moderated the positive relationship between annoyance and coping. PMID:27036252

    In this study, the occurrence of nine phthalate diesters (phthalates) and 14 organophosphorus flame retardants (PFRs) was investigated in 62 house dust samples collected from 19 buildings in Stockholm area during the year 2008. Eight phthalates were detected in almost all samples, with median concentrations ranging from 0.47 μg/g to 449 μg/g with di(2-ethylhexyl) phthalate being the most abundant compound. Twelve PFRs were detected with median concentrations ranging from 0.19 μg/g to 11 μg/g. Within this class of compounds, the most abundant were tris(2-chloroisopropyl) and tris(2-butoxyethyl) phosphate. Both classes of compounds were also measured in the air of the apartments, but no correlation between air and dust concentrations could be found. Based on these measurements, exposure, via house dust ingestion and air inhalation, was calculated for adults and toddlers, and compared to published limit values in order to estimate potential health risks. In an extreme exposure scenario for toddlers, di(2-ethylhexyl) phthalate, tris(2-chloroethyl) phosphate, tris(2-butoxyethyl) phosphate, and tributyl phosphate were close to the reference dose for chronic oral exposure or the tolerable daily intake. Standard Reference Material SRM 2585 was used as a quality control sample, and the levels of diisononyl and diisodecyl phthalates were determined in this material. PMID:25929991

    Full Text Available This research presents an evaluative energy model for estimating the energy efficiency of the design choices of architects and engineers in the early design phase. We analyze the effects of various parameters with different characteristics in various combinations for building energy consumption. With this analysis, we build a database that identifies a set of heuristic rules for energy-efficient building design to facilitate the design of sustainable apartment housing. Perturbation studies are based on a sensitivity analysis used to identify the thermal influence of the input design parameters on various simulation outputs and compare the results to a reference case. Energy sensitivity weight factors are obtained from an extensive sensitivity study using building energy simulations. The results of the energy sensitivity study summarized in a set of heuristic rules for evaluating architectural features are estimated through case studies of Korean apartment buildings. This study offers valuable guidelines for developing energy-efficient residential housing in Korea and will help architects in considering appropriate design schemes and provide a ready reference to generalized test cases for both architects and engineers so that they can zero in on a set of effective design solutions.

    The indoor air quality is directly affected by particulate matters (PM). In this study the concentration of indoor and outdoor particles of an apartment and an office were measured. The effect of the concentration of outdoor particles on the concentration of indoor particles was analyzed. The results demonstrate that concentration of indoor and outdoor particles has 2-3 peak points during one day. The indoor to outdoor ratio increases as the size of particles decreases, which indicates that the free particles penetrate through the building envelopes more easily. The concentration of indoor particles is closely correlated with the concentration of outdoor particles, and the correlation increases as the size of particles decreases.

    Full Text Available Apartments for university talent (AUT, are apartments provided to staff at non-market price, in order to attract outstanding scholars from around the world to work in universities and improve educational quality. This has been a critical issue in achieving social sustainability in China during rapid urbanization and industrialization. The agent construction mode has been adopted to build AUT because universities usually lack relevant management experience. The agent construction mode is a type of turnkey engineer construction based on the principal-agent model, project bidding mode, engineering contracting projects, and project supervision system. Risk factors are important considerations for both universities and agent construction companies. Although some studies have investigated the risk factors, only a few studies have identified the hierarchical structure of relevant risk factors. Therefore, the interrelationship and prioritization of the risk factors remain unknown, and this situation presents a barrier to better risk management. This paper investigates the interrelationship of risk factors with interpretative structural modeling (ISM. In addition, fuzzy MICMAC (matric d’impacts croises-multiplication appliqué a un classemen analysis was conducted to prioritize the risk factors. The findings provide useful references for better risk management of building AUT through the agent construction mode. Although this study focuses on China, the analytical process can also be generalized to other research topics and other countries.

  17. Study on the Development of an Optimal Heat Supply Control Algorithm for Group Energy Apartment Buildings According to the Variation of Outdoor Air Temperature

    2012-05-01

    Full Text Available In the present study, we have developed an optimal heat supply algorithm which minimizes the heat loss through the distribution pipe line in a group energy apartment. Heating load variation of a group energy apartment building according to the outdoor air temperature was predicted by a correlation obtained from calorimetry measurements of all households in the apartment building. Supply water temperature and mass flow rate were simultaneously controlled to minimize the heat loss rate through the distribution pipe line. A group heating apartment building located in Hwaseong city, Korea, which has 1473 households, was selected as the object building to test the present heat supply algorithm. Compared to the original heat supply system, the present system adopting the proposed control algorithm reduced the heat loss rate by 10.4%.

    From the perspective of global warming suppression and the depletion of energy resources, renewable energies, such as the solar collector (SC) and photovoltaic generation (PV), have been gaining attention in worldwide. Houses or buildings with PV and heat pumps (HPs) are recently being used in residential areas widely due to the time of use (TOU) electricity pricing scheme which is essentially inexpensive during middle-night and expensive during day-time. If fixed batteries and electric vehicles (EVs) can be introduced in the premises, the electricity cost would be even more reduced. While, if the occupants arbitrarily use these controllable loads respectively, power demand in residential buildings may fluctuate in the future. Thus, an optimal operation of controllable loads such as HPs, batteries and EV should be scheduled in the buildings in order to prevent power flow from fluctuating rapidly. This paper proposes an optimal scheduling method of controllable loads, and the purpose is not only the minimization of electricity cost for the consumers, but also suppression of fluctuation of power flow on the power supply side. Furthermore, a novel electricity pricing scheme is also suggested in this paper.

    A summary is presented of five independent field investigation surveys conducted across Canada for the Canada Mortgage and Housing Corporation. The intent of the investigations were to determine air exfiltration rates through the building envelope, inter-suite and inter-floor room leakage rates, and indoor air quality in a representative number of residential high rise apartment buildings. Air exfiltration, inter-suite and inter-floor air leakage rates were determined by conducting suite, floor and whole building fan depressurization tests. Indoor air quality was established by means of a survey of the tenants of the buildings, and by testing and monitoring for specific pollutants. Air leakage rates were found to be in excess of proposed guidelines of 0.05-0.14 l/s/m[sup 2] at 75 Pascals. The overall air leakage rates per unit of exterior wall during suite fan depressurization testing was in the range 2.10-3.15 l/s/m[sup 2] at a pressure differential of 50 Pascals across the exterior wall. When the corridor wall was not isolated leakage rates increased to 4.54-8.33 l/s/m[sup 2]. Air movement within a building with a high exterior wall leakage rate is predominately influenced by stack effect, combined with exterior wind direction and speed, while within a building with low leakage rates the predominant influences are stack effect and internal building activities such as elevators moving, doors opening, and movement of people. Ventilation supply air rates were generally inadequate to satisfy occupant requirements. 18 figs., 9 tabs.

  20. Production and distribution of domestic hot water in selected Danish apartment buildings and institutions. Analysis of consumption, energy efficiency and the significance for energy design requirements of buildings

    International Nuclear Information System (INIS)

    Highlights: ► Circulation system heat losses were 23–70% in apartment buildings. ► The use of additional heat meters in large buildings is recommended. ► The demand for domestic hot water, space heating and ventilation should be obtained. ► Domestic hot water will constitute a major part of future energy demand of dwellings. - Abstract: The goal of this work has been to document the efficiency of domestic hot water (DHW) distribution systems and to propose more energy efficient and environmentally friendly solutions for DHW systems based on analyses of existing conditions. In the article, measurements from 13 apartment buildings and two institutions are presented, i.e. consumption of DHW, heat loss from circulation lines and efficiency of the DHW system. The heat load and the cooling of the district heating water for DHW are documented as well. Possibilities for improving the DHW system include new types of circulation pipes, which have the potential of a 40% reduction of heat losses. In addition to the reduction of heat losses inside the building, a low return temperature from the hot water system will have a large impact on the heat losses from the district heating network when the building is being heated by district heating. It is likely that the production and distribution of DHW in buildings will constitute a dominant share of both the present, and in particular, the future energy design requirements of buildings. The results of this project could influence not only future buildings, but also existing buildings when renovation of installations take place

    Full Text Available Bed bugs (Cimex lectularius L. and Cimex hemipterus F. are among the most difficult urban pests to manage. Many essential oil-based bed bug control products that are considered reduced risk to mammals compared to synthetic insect neurotoxins have become commercially available, but their effectiveness as a stand-alone control method is unknown. This study assessed the field efficacy of an essential oil-based bed bug control product (EcoRaider; a.i. 1% geraniol + 1% cedar oil + 2% sodium lauryl sulfate compared to a pyrethroid and neonicotinoid mixture spray (0.075% Temprid SC; a.i. beta-cyfluthrin + imidacloprid. After 12 weeks, the three treatments—EcoRaider, Temprid SC, and EcoRaider + Temprid SC caused 92.5 ± 2.7, 92.9 ± 3.0, and 91.7% ± 2.7% bed bug count reduction, respectively. No significant differences existed in the bed bug reduction among the treatments. Bed bugs were eliminated from only 22% of the treated apartments. Among those still with bed bugs, 76% of the residents did not know bed bugs were present. We documented the residents’ self-control practices and discussed the potential of using essential oil-based insecticides in bed bug management programs to minimize the health risks to building occupants and pets and to slow down the development of insecticide resistance.

    Air sealing of building enclosures is a difficult and time-consuming process. Current methods in new construction require laborers to physically locate small and sometimes large holes in multiple assemblies and then manually seal each of them. The innovation demonstrated under this research study was the automated air sealing and compartmentalization of buildings through the use of an aerosolized sealant, developed by the Western Cooling Efficiency Center at University of California Davis.
    CARB sought to demonstrate this new technology application in a multifamily building in Queens, NY. The effectiveness of the sealing process was evaluated by three methods: air leakage testing of overall apartment before and after sealing, point-source testing of individual leaks, and pressure measurements in the walls of the target apartment during sealing. Aerosolized sealing was successful by several measures in this study. Many individual leaks that are labor-intensive to address separately were well sealed by the aerosol particles. In addition, many diffuse leaks that are difficult to identify and treat were also sealed. The aerosol-based sealing process resulted in an average reduction of 71% in air leakage across three apartments and an average apartment airtightness of 0.08 CFM50/SF of enclosure area.

    Full Text Available This paper examined the energy consumption of energy efficient buildings, and ascertained the extent to which these buildings are efficient when compared to normal buildings. For this purpose, the early literature regarding energy efficient buildings and the related elements have been reviewed, then three energy efficient buildings have been chosen and data collected from their occupants through a questionnaire. The data was then analysed by computing the average yearly electricity consumption per square feet, for both energy efficient buildings and normal buildings. A comparison of the results showed that the energy consumption in energy efficient buildings was almost half that of the normal buildings. Finally a few suggestions are proposed for promoting these types of energy efficient buildings which will eventually lead to economic growth and environment protection.

    2015-10-01

    Full Text Available Energy consumption in the world increases, so the measures in order to improve energy efficiency must be found. The aim of 2012/27/EU Energy Efficiency Directive targets is to decrease energy consumption for a final energy consumer by 1.5% every year, but there is no definition how these targets could be achieved by an individual member state. This article presents the analysis how these targets could be achieved by the means of individual heat metering by heat cost allocators for every flat thus decreasing an energy consumption for a final consumer. Statistical analysis of identical buildings with individual metering by heat cost allocators and without them is presented. Heat cost allocators do not decrease energy consumption by themselves, so this article presents a technical solution and a set of additional equipment, i.e. thermostatic valves, balance valves, hot water meters and remote data collection system that must be installed. The final results show that the targets of 2012/27/EU Energy Efficiency Directive in Lithuania can be reached, because the buildings with individual heat cost allocators consume about 20–30% less of heat energy.

    The Joens Ols block is an apartment house with 34 flats totalling a surface of 2877 m2. The building was constructed in 1998 with the objective of reducing the energy consumption by 50% without losses in comfort, robustness and simplicity of maintenance. This evaluation report builds on two years of monitoring. The house has conventional concrete framework with well insulated infill walls. Thermal bridges and air leaks are eliminated at all connections. Ventilation inlet is located behind the hot water-based radiators, forced ventilation exist i bathrooms and kitchens. Space heat is primarily generated by a exhaust/ambient air source heat pump supplemented by district heating. Heat and hot water consumption is metered and charged individually. Waste heat from the waste water is exchanged to preheat the household hot water. Solar and district heat is used for hot water production. Electric appliances, fans and pumps all have high energy efficiency. The evaluation shows that the objectives were met and that the prognoses were in good agreement with the outcome. In the report a detailed Analys is made of the profitability of the different components of the efficiency measures.

  10. Temperature conditions and heat supply of apartments in an apartment house with individual regulators

    Danilevskii, L. N.

    2011-03-01

    This paper presents the results of mathematical modeling of the values of the temperature and the heat source power in apartments of an apartment house with individual regulators. It has been shown that for the existing structures of buildings the heat transfer between apartments with individual thermoregulation strongly influences the values of the heat source power established in apartments in the process of regulation. Without changing the total heating load of the building, this process leads to considerable deviations of readings of the thermal energy meters in apartments from the thermal energy actually consumed for their heating. This fact throws doubt upon the expediency of installing individual calorimeters in an apartment house with thermoregulation in each apartment.

  15. Mine subsidence event at Washington West Apartments

    International Nuclear Information System (INIS)

    A major mine subsidence event occurred in Scranton, PA in early 1993. The initial damage included breakage of gas and water lines, cracking of pavements and sidewalks, and architectural damage to the seven-story apartment building that houses about 150 elderly persons. Visible damage include a 3/4-in dilation of the expansion joint separating the building, approximately 200 interior and exterior cracks, and distress to utility lines. The Office of Surface mining Reclamation and Enforcement (OSM) funded an integrated geotechnical and structural engineering investigation to determine the cause of the subsidence, the limits of affected areas, and the nature of damage to the building. Work included interior surveys, exterior surveys, installation of crack gages, eight subsurface borings, review of building design drawings, review of geologic and mining data, and structural analysis of the rigid steel frame building. The surveys showed the building had undergone movements consisting of a lateral translation, a longitudinal differential settlement, and a transverse differential settlement. Preliminary structural analyses showed that the differential settlements had introduced significant additional stresses in some of the building columns. This paper provides a case history of the cause and effects of the subsidence event. The techniques used to collect and analyze the data are presented along with the findings of the geotechnical and structural engineering investigations. The paper also describes emergency actions that were implemented, the remedial alternatives that were considered, and the method selected as the recommended alternative

    Fisk, William J.; Norris, Federico; Singer, Brett C.

    2013-11-01

    Monthly gas and electricity use data from a set of 13 study apartments and 20 control apartments from three apartment buildings (B1 B3) in California were analyzed. The study apartments were retrofit with simultaneous energy savings and indoor environmental quality (IEQ) improvements as the goal. The control apartments were not retrofit. Pre-retrofit modeling indicated annual energy savings of 21percent, 17percent, and 27percent for the study apartments in B1-B3, respectively. Based on a comparison of changes in energy use of study apartments to energy use changes of control apartments, total measured savings of gas energy plus site electrical energy were 28percent in B1, 5percent in B2, and 3percent in B3. Given the small number of study apartments and the substantial changes in energy use within control apartments, the project yielded no conclusive evidence of energy savings. Apartment energy use increased with number of occupants and with floor area; however, the association with occupancy was most evident. Climate differences did not appear to be the major driver for the variability in energy use among apartments. Changes in occupant behaviors affecting energy use may have overwhelmed and obscured the energy savings in this small number of buildings. Much larger prior studies employing similar retrofits indicate that the retrofits usually do save energy.

    Sixteen apartments serving low-income populations in three buildings were retrofit with the goal of simultaneously reducing energy consumption and improving indoor environmental quality (IEQ). Retrofit measures varied among apartments and included, among others, envelope sealing, installation of continuous mechanical ventilation systems, upgrading bathroom fans and range hoods, attic insulation, replacement of heating and cooling systems, and adding wall-mounted particle air cleaners. IEQ parameters were measured, generally for two one-week periods before and after the retrofits. The measurements indicate an overall improvement in IEQ conditions after the retrofits. Comfort conditions, bathroom humidity, and concentrations of carbon dioxide, acetaldehyde, volatile organic compounds, and particles generally improved. Formaldehyde and nitrogen dioxide levels decreased in the building with the highest concentrations, were unchanged in a second building, and increased in a third building. IEQ parameters other than particles improved more in apartments with continuous mechanical ventilation systems installed. In general, but not consistently, larger percent increases in air exchange rates were associated with larger percent decreases in indoor levels of the pollutants that primarily come from indoor sources.

    2015-07-01

    Air sealing of building enclosures is a difficult and time-consuming process. Current methods in new construction require laborers to physically locate small and sometimes large holes in multiple assemblies and then manually seal each of them. This research study by Building America team Consortium for Advanced Residential Buildings demonstrated the automated air sealing and compartmentalization of buildings through the use of an aerosolized sealant developed by the Western Cooling Efficiency Center at University of California Davis. CARB demonstrated this new technology application in a multifamily building in Queens, NY. The effectiveness of the sealing process was evaluated by three methods: air leakage testing of overall apartment before and after sealing, point-source testing of individual leaks, and pressure measurements in the walls of the target apartment during sealing. Aerosolized sealing was successful by several measures in this study. Many individual leaks that are labor-intensive to address separately were well sealed by the aerosol particles. In addition, many diffuse leaks that are difficult to identify and treat were also sealed. The aerosol-based sealing process resulted in an average reduction of 71% in air leakage across three apartments and an average apartment airtightness of 0.08 CFM50/SF of enclosure area.

    2006-01-01

    We analyse fall-apart decays of poliquark (tetra, penta and molecule type) hadrons within the constituent quark picture. For processes in which a poliquark hadron goes to final states containing a light pseudoscalar meson the constraints given by chiral symmetry are implemented. As an application of the approach developed, fall-apart decays of $a(980)$ and X(3872) are studied, assuming these mesons are poliquark hadrons. Two extreme options - confined diquark-diquark states and molecular states - are considered. For $a^0(980)$, the observed width can be obtained assuming that this meson is a diquark-diquark composite with a relatively large size of around $1\\div 1.5$ fm. The pure $K \\bar K $ molecular-type state, however, can be excluded. For the X(3872), a sufficiently small width can be obtained if it is a dominantly isospin-0 diquark-diquark composite with a very large size of $\\ge 2.5$ fm. The pure molecular option appears possible if the binding energy is tiny, $E_b\\lesssim 0.2$ MeV, corresponding to a h...

  9. HUBBLE WATCHES STAR TEAR APART ITS NEIGHBORHOOD

    Science.gov (United States)

    2002-01-01

    NASA's Hubble Space Telescope has snapped a view of a stellar demolition zone in our Milky Way Galaxy: a massive star, nearing the end of its life, tearing apart the shell of surrounding material it blew off 250,000 years ago with its strong stellar wind. The shell of material, dubbed the Crescent Nebula (NGC 6888), surrounds the 'hefty,' aging star WR 136, an extremely rare and short-lived class of super-hot star called a Wolf-Rayet. Hubble's multicolored picture reveals with unprecedented clarity that the shell of matter is a network of filaments and dense knots, all enshrouded in a thin 'skin' of gas [seen in blue]. The whole structure looks like oatmeal trapped inside a balloon. The skin is glowing because it is being blasted by ultraviolet light from WR 136. Hubble's view covers a small region at the northeast tip of the structure, which is roughly three light-years across. A picture taken by a ground-based telescope [lower right] shows almost the entire nebula. The whole structure is about 16 light-years wide and 25 light-years long. The bright dot near the center of NGC 6888 is WR 136. The white outline in the upper left-hand corner represents Hubble's view. Hubble's sharp vision is allowing scientists to probe the intricate details of this complex system, which is crucial to understanding the life cycle of stars and their impact on the evolution of our galaxy. The results of this study appear in the June issue of the Astronomical Journal. WR 136 created this web of luminous material during the late stages of its life. As a bloated, red super-giant, WR 136 gently puffed away some of its bulk, which settled around it. When the star passed from a super-giant to a Wolf-Rayet, it developed a fierce stellar wind - a stream of charged particles released from its surface - and began expelling mass at a furious rate. The star began ejecting material at a speed of 3.8 million mph (6.1 million kilometers per hour), losing matter equal to that of our Sun's every 10

    This research effort sought to achieve a solution package that yields energy savings greater than 30% over the pre-existing conditions in a minimally intrusive multifamily retrofit project. The Consortium for Advanced Residential Buildings (CARB) partnered with L+M Development Partners, Inc. on a Mitchell-Lama Housing Program project, Marcus Garvey Village, in Brooklyn, NY (Climate Zone 4A). The Mitchell-Lama Housing Program is a form of housing subsidy in the state of New York that provides affordable rental and cooperative housing to moderate- and middle-income families. Marcus Garvey Village was founded in 1975 and contains 625 residential units (ranging from studios to 5-bedroom units) in thirty-two 4-story garden-style apartment structures built with concrete and faced in light brown brick. The single largest challenge for implementation of energy conservation measures at Marcus Garvey was working within occupied spaces. Measures are being implemented in phases to minimize disruption. As of August 2015, the retrofit work is over 50% complete. The wall insulation, sealing of the through wall AC vent, and installation of new oil-filled electric baseboards with advanced controls are conducted at one time, limiting disruption to the living room space. In a similar fashion, the kitchen work is done, then the bathroom. The final selection of energy conservation measures is projected to save 26.5% in source energy with a cost just under $3.7 million and utility bill savings of nearly $480,000 (of an average $1.8 million annual utility cost for the development).

    Kids love to build robots, letting their imaginations run wild with thoughts of what they might look like and what they could be programmed to do. Yet when students use cereal boxes and found objects to make robots, often the projects look too similar and tend to fall apart. This alternative allows students to "build" robots in a different way,…

    Full Text Available The block type and structural systems in buildings affect the amount of building materials required as well as the CO2 emissions that occur throughout the building life cycle (LCCO2. The purpose of this study was to assess the life cycle CO2 emissions when an apartment housing with ‘flat-type’ blocks (the reference case was replaced with more sustainable ‘T-type’ blocks with fewer CO2 emissions (the alternative case maintaining the same total floor area. The quantity of building materials used and building energy simulations were analyzed for each block type using building information modeling techniques, and improvements in LCCO2 emission were calculated by considering high-strength concrete alternatives. By changing the bearing wall system of the ‘flat-type’ block to the ‘column and beam’ system of the ‘T-type’ block, LCCO2 emissions of the alternative case were 4299 kg-CO2/m2, of which 26% was at the construction stage, 73% was as the operational stage and 1% was at the dismantling and disposal stage. These total LCCO2 emissions were 30% less than the reference case.

    This paper uses a random utility model to estimate consumers' valuation of energy efficient insulation and ventilation systems in rental apartments. Given consumers' limited experience in residential buildings and the perceived uncertainty about their comfort benefits and resulting energy savings, these relatively new technologies might be undervalued by risk-averse consumers. Using the concept of certainty-equivalence, this paper proposes a model to assess the consumers' risk-aversion for adopting energy-efficient systems. These systems are treated as risky assets while conventional commodities are assumed to be risk-free. The curvature of the utility function is interpreted as a measure of aversion to perceived risks as opposed to explicit risks measured by observed variances. The proposed formulation is applicable in stated preference data with qualitative variables. The model is applied to data from a choice experiment conducted among 264 apartment tenants in Switzerland. The estimated curvatures reject the risk-neutrality hypothesis. The range of the estimated risk premiums suggests that risk considerations remain a central issue in dealing with energy efficiency in residential buildings. The analysis also indicates that assuming same risk attitudes toward new and conventional systems could bias the estimates of the willingness to pay, especially when the system is comprised of several components.

    1980-12-31

    The apartment building would consist of about 75 units of about 900 square feet each. Also included would be an outdoor swimming pool and an enclosed activity wing of about 11,000 square feet. Though no deep geothermal wells have been drilled in the immediate area, opinions were obtained that 150/sup 0/F water would be present at 2500 feet and 80/sup 0/F water at about 1000 feet. Based on this information the comparative economics of using geothermal as a heat source versus conventional electrical heating was developed. The purpose of this comparison is to determine if there is economic incentive for the expenditure necessary to define and prove the extent of the geothermal resource. Four systems were compared, each would provide space heating, supply domestic hot water, and heat the swimming pool. A brief description of each of the systems is given. (MHR)

    Bacterial growth in hot water systems seems to cause problems such as bad odor of the water, skin allergies and increased heat transfer resistance in heating coils. In order to establish a basis for long-term suppression of bacterial growth, we studied the distribution of bacteria in a Danish domestic hot water system. Heterotrophic plate counts (HPC) were measured in both water and biofilm samples from various sampling sites in the system. In hot water samples, where the temperature was 55-60 degrees C, the HPC were 10(3)-10(4)CFU/mL at incubation temperatures of 25 degrees C or 37 degrees C and 10(5)CFU/mL at 55 degrees C or 65 degrees C. In the cold water (10 degrees C) supplying the hot water system, the HPC at 25 degrees C or 37 degrees C was lower than in the hot water, and no bacteria were found after incubation at 55 degrees C or 65 degrees C. HPC constituted from 38% to 84% of the AODC results in hot water but only 2% in cold water, which showed a high ratio of culturable bacteria in hot water. Biofilm samples from the hot water tank and the inner surface of the pipes in the cold and hot water distribution system were collected by specially designed sampling devices, which were exposed in the system for 42 days. The quasi-steady-state number of bacteria in the biofilm, measured as the geometric mean of the HPC obtained between 21 and 42 days, was five-fold higher in the hot water pipe (13x10(5)CFU/cm(2) at 55 degrees C) than in the cold water pipe (2.8x10(5)CFU/cm(2) at 25 degrees C). There was no significant difference between the number of bacteria in the biofilm samples from the top, middle and bottom of the hot water tank, and the number of bacteria in the biofilm counted at 55 degrees C ranged from 0.6x10(4) to 1.7x10(4)CFU/cm(2). The surfaces of the sacrificial aluminum anodes and the heating coils in the hot water tank also contained high bacterial numbers. The measured number of bacteria in water and biofilm samples was related to the dimensions of the hot water system, and calculations showed that the majority of bacteria (72%) were located in the biofilm especially in the distribution system, which accounts for the greatest surface area. Free-living bacteria accounted for 26% and only a minor part of the bacteria were in the sludge in the hot water tank (2%). PMID:14630121

  20. Domestic Hot Water Production with Ground Source Heat Pump in Apartment Buildings

    Directory of Open Access Journals (Sweden)

    Jukka Yrjölä

    2015-08-01

    Full Text Available Producing domestic hot water (DHW with a ground source heat pump (GSHP is challenging due to the high temperature (HT of DHW. There are many studies proving the better performance of cascade heat pumps compared to single-stage heat pumps when the difference between the condensing and the evaporation temperature is large. In this system approach study, different GSHP arrangements are described and computationally compared. A two-stage heat pump arrangement is introduced in which water tanks of the heating system are utilized for warming up the DHW in two stages. It is shown that the electricity consumption with this two-stage system is approximately 31% less than with the single-stage heat pump and 12% less than with the cascade system. Further, both low temperature (LT and HT heat pumps can run alone, which is not common in cascade or other two-stage heat pumps. This is advantageous because the high loads of the space heating and DHW production are not simultaneous. Proper insulation of the DHW and recirculation pipe network is essential, and drying towel rails or other heating coils should be avoided when aiming for a high efficiency. The refrigerants in the calculations are R407C for the LT heat pump and R134a for the HT heat pump. Investment costs are excluded from calculations.

    The present work reports the variation of 31 carbonyl compounds (CC) in an apartment located at Niterói City, Rio de Janeiro State, Brazil. Eight sampling campaigns were conducted through a 1-year period, and three areas (living room, kitchen, and bedroom) were evaluated before, during, and after the renovation activities and reoccupation of the apartment. Samples were collected using SEP-PAK cartridges impregnated with 2,4-dinitrophenylhydrazine, and the hydrazones were analyzed using rapid resolution liquid chromatography with UV detection. The lowest total concentration of CC (19.0 ± 1.5 μg m(-3)) was found before the renovation when the apartment was empty, but door varnishing resulted in highest contamination of the apartment (1386 ± 384 μg m(-3)); however, an important dispersion of CC was observed in the subsequent sampling (148 ± 1.8 μg m(-3)). After apartment reoccupation, the indoor contamination seemed to depend on the routine activities taken there, such as household product use and cooking activities, but apparently, local temperature increase favored the vaporization of the volatile CC from the building materials in the apartment. As far as we are concerned, this is the first study comparing the concentrations of 31 CC in residential areas before, during, and after renovation activities taken in Brazil. PMID:27130339

    There is little thermal comfort research in residential environments reported from India. Energy consumption in Indian residential buildings is one of the highest, increasing at a phenomenal rate. Indian standards advocate two narrow ranges of temperatures for all building and climate types. In this context, a field study in summer and monsoon was conducted following Class-II protocols, for three months in 2008, in naturally ventilated apartment buildings in Hyderabad. Over a 100 subjects involved, giving 3962 datasets. In May, most of the subjects were uncomfortable, preferring a temperature on the cooler side of the neutrality, despite accepting their thermal environments. Thermal sensation, preference and acceptance improved in June and July as temperature receded. Humidity did not affect comfort sensation much, as summer was hot and dry. Conversely, increase in humidity adversely affected the thermal comfort in June. Adaptive use of controls resulted in moderate air movement indoors, adequate for sweat evaporation most of the time. The subjects used traditional ensembles and slowed down their activities adaptively to restore thermal comfort. Clothing adaptation was found to be impeded by many socio-cultural and economic aspects. The comfort band (voting within -1 and +1) based on the regression analysis was found to be 26-32.45 C with the neutral temperature at 29.23 C. This is way above the limits (23-26 C) set by Indian standards. The PMV was always found to be higher than the actual sensation vote. These findings have far reaching energy implications in a developing country like India. (author)

    2016-05-01

    Full Text Available In each country in the world, there is a strong need for all industries to reduce CO2 emissions for sustainable development as a preparation for climatic change. The biggest issue in many developed countries, including the United States, is to reduce CO2 emissions for the upcoming implementation of Carbon Emissions Trading. The construction industry, in particular, which accounts for up about 30% of CO2 emissions, will need studies on the amount of CO2 emissions. The purpose of this study is to present the most environmentally friendly and economical apartment house plan types according to the increasing number of layers by evaluating the amount of CO2 emissions and economic efficiency. The results indicated that flat and Y-shaped types are more eco-friendly and economical in lower levels of less than 20 stories. However, the L-shaped type is more highly eco-friendly and economically efficient in higher levels of more than 20 stories. The results of this paper would help to make a decision on the building types and the number of stories in the early stages of construction.

    2011-10-01

    Building on Deci and Ryan's Self-Determination Theory and Meijman and Mulder's Effort-Recovery Model, the present study examined the nature, antecedents, and consequences of working hard (i.e., workaholism and work engagement) in a Dutch convenience sample of 1,246 employees. A confirmatory factor analysis showed that workaholism and work engagement were two largely independent concepts. Crossing these two concepts yielded four types of workers: workaholic employees, engaged employees, engaged workaholics, and nonworkaholic/nonengaged employees. MANOVA and subsequent ANOVAs were used to compare these four groups regarding their motivation, working hours, and levels of burnout. As expected, study results revealed that workaholic employees were driven by controlled motivation, whereas engaged employees were driven by autonomous motivation. Engaged workaholics were driven by both controlled and autonomous motivation. In addition, the results revealed that engaged workaholics spent most time on working. Unlike workaholic employees, engaged workaholics did not experience the highest levels of burnout, suggesting that high engagement may buffer the adverse consequences of workaholism. The present study emphasizes the importance of differentiating among at least three categories of employees who work hard: workaholic employees, engaged employees, and-for the first time-engaged workaholics.

    2016-08-01

    Recent experiments have demonstrated that outdoor ozone reacts with materials inside residential building enclosures, potentially reducing indoor exposures to ozone or altering ozone reaction byproducts. However, test methods to measure ozone penetration factors in residences (P) remain limited. We developed a method to measure ozone penetration factors in residences under infiltration conditions and applied it in an unoccupied apartment unit. Twenty-four repeated measurements were made, and results were explored to (i) evaluate the accuracy and repeatability of the new procedure using multiple solution methods, (ii) compare results from 'interference-free' and conventional UV absorbance ozone monitors, and (iii) compare results against those from a previously published test method requiring artificial depressurization. The mean (±s.d.) estimate of P was 0.54 ± 0.10 across a wide range of conditions using the new method with an interference-free monitor; the conventional monitor was unable to yield meaningful results due to relatively high limits of detection. Estimates of P were not clearly influenced by any indoor or outdoor environmental conditions or changes in indoor decay rate constants. This work represents the first known measurements of ozone penetration factors in a residential building operating under natural infiltration conditions and provides a new method for widespread application in buildings.

  14. Small might be beautiful, but bigger performs better: Scale economies in “green” refurbishments of apartment housing

    International Nuclear Information System (INIS)

    The energy efficiency of the residential housing stock plays a key role in strategies to mitigate climate change and global warming. In this context, it is frequently argued that private investment and the quality of thermal upgrades are too low in the light of the challenges faced and the potential energy cost savings. While many authors address the potential barriers for investors to increase energy efficiency, studies on the capabilities of different investors to reduce energy requirements of their property are scarce. This study investigates potential advantages of housing company's size, i.e. economies of scale, economies of scope and institutional learning in thermal upgrades of residential housing. Based on unique data on energy consumption in 102,307 apartment buildings in Germany, we present new evidence for the advantages and disadvantages of a housing company's size in “green” retrofitting projects. Our estimations show, that large housing companies outperform private landlords by far in high effort refurbishment projects. In contrast, private landlords appear to have advantages in low effort, incremental refurbishment activities. We demonstrate that a substantial share of the advantages of larger firms can be associated with specialization (i.e. repeated projects). The results offer new options for policy makers to refine the support schemes toward a low carbon housing stock. - Highlights: • First study to analyze the effects of housing companies size on “green” refurbishment • Economies of scale, scope and learning all affect energy efficiency refurbishments. • Specialization on distinct refurbishments influences outcome of thermal upgrades. • Analysis based on a large and unique sample of apartment buildings in Germany

    Full Text Available Apartments are a viable and a popular choice for people who live in some urban regions. Based on this understanding, this study aims to analyze the apartments in the city of Santa Maria, Rio Grande do Sul, Brazil, using descriptive statistics and factor analysis. In order to study that, a sample of 120 apartments was obtained in real estate sites of that city and the data collection instrument was composed of 14 variables defined by means of literature. Through descriptive analysis, the results have shown that predominantly apartments had two rooms or more and were located into the most valued part of the city. While in factor analysis, by principal component analysis, they identified five factors, of which only two had more than two variables, enabling deeper understanding. These factors were named as quality status and functional characteristics.

    The gas monitoring system for elders' apartment using QCM sensors was newly developed. The QCM sensors for sulfide gas and ammonia gas were used for this system. The system for bodily wastes was fabricated and applied to nursing care system in elders' apartment. This system is composed by the sensor unit, communication unit and data server. Care person can see whether the linen should be changed or not without seeing over each room. The QCM sensors have some problems such as the interference of humidity and temperature, therefore these influences were dissolved using humidity sensor and temperature sensor as feedback source. The sensors were placed in several points of elders' apartment for 2 weeks. This system can be used in elders' apartment successfully.

    Full Text Available Among living arrangements, living apart together relationships arouse curiosity on the part of sociologists, demographers and even the media. From a scientific point of view, how have noncohabiting relationships evolved in recent decades? How can we recognise these relationships, and who are the populations concerned? The present study provides an overall view into noncohabiting relationships in France, shedding light on the characteristics of both the individuals concerned and their relationships. There has been no recent increase in the prevalence of this living arrangement. It competes with cohabiting relationships both among students and among people with cohabiting children. Four main groups of living apart relationships are described: "Young adults", "Out of a family", "Seniors." The reasons for living apart as well as future intentions vary considerably across these groups.

    Full Text Available Practice shows, that constructive elements the most damaged by the environmental conditions are external walls of apartment houses and, accordingly, these constructive elements demand a complex estimation of their condition about decreasing of their operational characteristics which provide their bearing ability and heat-shielding properties, and development of ways of a prolongation of an operational resource.In the given work the structure of silicate brick is analyzed, questions of a technical condition, the forecast and ways of prolongation of a residual operational resource of external walls of buildings on the basis of a silicate brick of construction 40 - 70 уеаrs are considered. The analysis is made using physical and chemical methods on an example of an available housing of this category in cities of Republic Bashkortostan. The received results of a condition of buildings external walls laying allow to make a conclusion about decreasing of silicate brick external wall bearing ability for the long period of operation (?70 years within the limits of up to 10-15% due to reduction of effective section by 7-12%, decreasing in durability of a facing brick to 15-20%. Materials (a brick and a masonry mortar of external walls of buildings deeper layers are in much better or even in practically initial condition that is proved out by the big number of inhabited objects inspections. Prolongation of a residual operational resource of an external wall on the basis of a silicate brick is possible by its protection by waterproofing materials (plaster systems, waterproof getting compositions in a combination of the named systems of hydro-protection with effective facade heat-insulation.

    Sun, Wenning; Li, Mingxin; Han, Yinong; Wang, Moqi; Ansourian, Peter

    2016-08-01

    In this project, one single level of the Façade Greening was designed and modelled using finite element method in Strand7. A static analysis was performed in order to understand the deflection and the stress due to the extra loads imposed by the soil and plants. The results produced by the linear static solver are compared with the strength of the materials and the European limitations. The maximum tension stress which exceeds the tensile strength in concrete is found in the root of the cantilever balcony. An alternative design of the cantilevered balcony with pre-stressed concrete slab is modelled separately for the balcony. Decrease is found in the tension stress and the significant improvement of deflection of the balcony with pre-stressed concrete slab. The dynamic loads such as wind and earthquake did not suggest significant effect on the pre-stressed concrete slab.

  15. Building America Case Study: Solar Water Heating in Multifamily Buildings

    Energy Technology Data Exchange (ETDEWEB)

    R. Aldrich and J. Williamson

    2016-05-01

    Solar domestic hot water (SDHW) systems have been installed on buildings for decades, but because of relatively high costs they have not achieved significant market penetration in most of the country. As more buildings move towards zero net energy consumption, however, many designers and developers are looking more closely at SDHW. In multifamily buildings especially, SDHW may be more practical for several reasons: (1) When designing for zero net energy consumption, solar water heating may be part of the lowest cost approach to meet water heating loads. (2.) Because of better scale, SDHW systems in multifamily buildings cost significantly less per dwelling than in single-family homes. (3) Many low-load buildings are moving away from fossil fuels entirely. SDHW savings are substantially greater when displacing electric resistance water heating. (4) In addition to federal tax incentives, some states have substantial financial incentives that dramatically reduce the costs (or increase the benefits) of SDHW systems in multifamily buildings. With support form the U.S. DOE Building America program, the Consortium for Advanced Residential Buildings (CARB) worked with a developer in western Massachusetts to evaluate a SDHW system on a 12-unit apartment building. Olive Street Development completed construction in spring of 2014, and CARB has been monitoring performance of the water heating systems since May 2014.

  16. Review of low-energy construction, air tightness, ventilation strategies and indoor radon: results from Finnish houses and apartments

    International Nuclear Information System (INIS)

    Low-energy and passive house construction practices are characterised by increased insulation, high air tightness of the building shell and controlled mechanical ventilation with heat recovery. As a result of the interaction of mechanical ventilation and high air tightness, the pressure difference in a building can be markedly enhanced. This may lead to elevated indoor radon levels. Minor leakages in the foundation can affect the radon concentration, even in the case where such leaks do not markedly reduce the total air tightness. The potential for high pressures to affect indoor radon concentrations markedly increases when the air tightness ACH50, i.e. the air change per hour induced by a pressure difference of 50 Pa, is -1. Pressure differences in Finnish low-rise residential houses having mechanical supply and exhaust ventilation with heat recovery (MSEV) are typically 2-3 Pa, clearly lower than the values of 5-9 Pa in houses with only mechanical exhaust ventilation (MEV). In MSEV houses, radon concentrations are typically 30 % lower than in MEV houses. In new MSEV houses with an ACH50 of 0.6 h-1, the limit for passive construction, the analytical estimates predict an increase of 100 % in the radon concentration compared with older houses with an ACH50 of 4.0 h-1. This poses a challenge for efficient radon prevention in new construction. Radon concentrations are typically 30 % lower in houses with two storeys compared with only one storey. The introduction of an MSEV ventilation strategy in typically very airtight apartments has markedly reduced pressure differences and radon concentrations. (authors)

    CERN Document Server

    Kaiser, David

    2005-01-01

    Winner of the 2007 Pfizer Prize from the History of Science Society. Feynman diagrams have revolutionized nearly every aspect of theoretical physics since the middle of the twentieth century. Introduced by the American physicist Richard Feynman (1918-88) soon after World War II as a means of simplifying lengthy calculations in quantum electrodynamics, they soon gained adherents in many branches of the discipline. Yet as new physicists adopted the tiny line drawings, they also adapted the diagrams and introduced their own interpretations. Drawing Theories Apart traces how generations of young theorists learned to frame their research in terms of the diagrams—and how both the diagrams and their users were molded in the process.Drawing on rich archival materials, interviews, and more than five hundred scientific articles from the period, Drawing Theories Apart uses the Feynman diagrams as a means to explore the development of American postwar physics. By focusing on the ways young physicists learned new calcul...

  5. Evaluation of Parental Satisfaction of Children's Spaces Within High Rise Apartment Environments

    Directory of Open Access Journals (Sweden)

    2014-11-01

    Full Text Available In the design process of open spaces within residential apartments, little attention is paid to children and their attitude to the environment is often ignored. Children, especially those who live in high-rise apartments, were found to have less connection with nature. Children supposedly need to engage in physical activities within outdoor areas, but urban planners, with the approval of managers or parents, must adequately design the open space for children. This paper initially reviews different research in this area. It consequently attempts to evaluate parental satisfaction regarding children's connectivity to open spaces as a dependent variable, and their preferences and perception of safety as independent variables. The research method is based on a questionnaire survey addressed to 261 parents and adults, in two localities in Tehran, Iran. The result of this research shows that parental attitude to open space has an effect on children's outdoor activities. Moreover, parents with young children express lower satisfaction to open spaces than those adults without young children. Families with children need open spaces in residential high-rise apartments for their siblings’ physical activities, and the designers should consider such an important need.

    1975-01-01

    Solar energy has been used for space heating and water heating for many years. A less common application, although technically feasible, is solar cooling. This paper describes the techniques employed in the heating and cooling of buildings, and in water heating. The potential for solar energy to displace conventional energy sources is discussed. Water heating for new apartments appears to have some features which could make it a place to begin the resurgence of solar energy applications in the United States. A project to investigate apartment solar water heating, currently in the pilot plant construction phase, is described.

  9. Carbon Efficient Building Solutions

    Directory of Open Access Journals (Sweden)

    Pellervo Matilainen

    2010-03-01

    Full Text Available Traditionally, the Finnish legislation have focused on energy use and especially on energy used for heating space in buildings. However, in many cases this does not lead to the optimal concept in respect to minimizing green house gases. This paper studies how CO2 emission levels are affected by different measures to reduce energy use in buildings. This paper presents two real apartment buildings with different options of energy efficiency and power sources. The calculations clearly show that in the future electricity and domestic hot water use will have high importance in respect to energy efficiency, and therefore also CO2 equivalent (eq emissions. The importance increases when the energy efficiency of the building increases. There are big differences between average Finnish production and individual power plants; CO2 eq emissions might nearly double depending on the energy source and the power plant type. Both a building with an efficient district heating as a power source, and a building with ground heat in addition to nuclear power electricity as a complimentary electricity source performed very similarly to each other in respect to CO2 eq emissions. However, it is dangerous to conclude that it is not important which energy source is chosen. If hypothetically, the use of district heating would dramatically drop, the primary energy factor and CO2 eq emissions from electricity would rise, which in turn would lead to the increase of the ground heat systems emissions. A problem in the yearly calculations is that the fact that it is very important, sometimes even crucial, when energy is needed, is always excluded.

  14. Seasonal cycle of indoor-VOCs: comparison of apartments and cities

    Science.gov (United States)

    Schlink, U.; Rehwagen, M.; Damm, M.; Richter, M.; Borte, M.; Herbarth, O.

    On the basis of 2103 measurements of volatile organic compounds (VOCs) in indoor air we study the intensity of a seasonal pattern. The data are representative for the German population and were gathered in different cities (Leipzig, München, Köln), in rooms of different type (children's, living, sleeping rooms, and other rooms), and in households of smokers and non-smokers. In addition to the randomly selected different apartments that were sampled each month, we repeatedly measured in a fixed set of 10 apartments. The analysis comprised concentrations of 30 VOCs belonging to the groups of alkanes, cycloalkanes, aromatics, volatile halogenated hydrocarbons, and terpenes. The annual cycle for total VOC concentrations was observed at every site. Seasonality proved to be the most dominant pattern, but it may be modified by further factors, such as the city, the considered VOC component, and the type of the considered room. Highest concentrations occurred during the winter months and amount to approximately three to four times the summer burden. As seasonality may bias the results of health effect studies we fit a seasonal model to our measurements and develop a procedure for seasonal adjustment, which enables to roughly estimate the annual peak concentration utilizing one monthly observation. The seasonal pattern proved to be a general feature of indoor VOC concentrations and, therefore, this adjustment procedure may be generally applicable. For Leipzig, München, and Köln we present site-specific adjustment factors for indoor concentrations of aromatics, terpenes, and alkanes.

  15. Pull-apart origin of the Satpura Gondwana basin, central India

    Indian Academy of Sciences (India)

    2005-06-01

    The Gondwana basins of peninsular India are traditionally considered as extensional-rift basins due to the overwhelming evidence of fault-controlled synsedimentary subsidence. These basins indeed originated under a bulk extensional tectonic regime, due to failure of the attenuated crust along pre-existing zones of weakness inherited from Precambrian structural fabrics. However, disposition of the basins and their structural architecture indicate that the kinematics of all the basins cannot be extensional. To maintain kinematic compatibility with other basins as well as the bulk lateral extension, some basins ought to be of strike-slip origin. The disposition, shape and structural architecture of the Satpura basin, central India suggest that the basin could be a pull-apart basin that developed above a releasing jog of a left-stepping strike-slip fault system defined by the Son-Narmada south fault and Tapti north fault in consequence to sinistral displacement along WSW-ENE. Development of a sedimentary basin under the above-mentioned kinematic condition was simulated in model experiments with sandpack. The shape, relative size, stratigraphic and structural architecture of the experimental basin tally with that of the Satpura basin. The experimental results also provide insights into the tectono-sedimentary evolution of the Satpura basin in particular and pull-apart basins in general.

    Full Text Available Chinua Achebe in his novel Things Fall Apart gives us a unique picture of life in Africa before the arrival of Christianity and colonization and the era afterwards. He shows how African people lost their traditional culture and values, replacing them with foreign beliefs. In this article, the way black people lived before the arrival of white people, how they encountered and reacted to white colonizers, in addition to how they converted to Christianity and subsequently to White culture, as portrayed in this novel, will be analyzed. The purpose of this study is to trace the roots of this rapid pace of colonialism back to when colonial subjects lost their original culture to the new-coming people and to what extent those colonized people were affectively actualizing their inferiority and subordination to the white society. Frantz Fanon’s theories on the relation between language and culture or language and civilization, as well as his discussion of White notion of Blacks and Blacks’ conception of themselves are discussed and analyzed in Achebe’s masterpiece Things Fall Apart to prove that black people attempted to make up for their deep feeling of incompleteness by imitating white people and forming a white personality in a black statue as a result of their own conscious volition.

    Full Text Available Eastern Europe today is confronted with an unavoidable problem - the multifamily apartment building stock is deteriorating but apartment owners do not have sufficient access to resources be they organizational, financial, technical or legal. In addition, destructive myths have grown about the Soviet era buildings despite their continued resilience or the ex- GDR experience in the 90s with the same buildings. Further, without resources, decision making in residential apartments is seen as a major obstacle and used as an explanation why renovation has not taken place in Latvia. This is important not only in the context of a potential housing crisis but also because the renovation of the apartment buildings is an effective solution to significantly reduce the energy consumption and greenhouse gas emissions. It has a proven potential to effectively finance the long term renovation of these buildings. This paper summarizes the first findings of a comprehensive and in-depth study of apartment buildings, their owners and the processes relating to renovation, combining social and environmental engineering research methods. It seeks to understand how owners of multi-family buildings in Eastern Europe understand their buildings and then to answer two questions - how to motivate owners to renovate their homes and increase energy efficiency and what business models should be used to implement economically viable and high quality projects.

    Full Text Available Background: Most research asks whether or not cohabitation has come to rival marriage. Little is known about the meaning of living apart together (LAT relationships, and whether LAT is an alternative to marriage and cohabitation or a dating relationship. Objective: We examine across Europe: (1 the prevalence of LAT, (2 the reasons for LAT, and (3 the correlates of (a LAT relationships vis-à-vis being single, married, or cohabiting, and (b different types of LAT union. Methods: Using Generations and Gender Survey data from ten Western and Eastern European countries, we present descriptive statistics about LATs and estimate multinominal logistic regression models to assess the correlates of being in different types of LAT unions. Results: LAT relationships are uncommon, but they are more common in Western than Eastern Europe. Most people in LAT unions intend to live together but are apart for practical reasons. LAT is more common among young people, those enrolled in higher education, people with liberal attitudes, highly educated people, and those who have previously cohabited or been married. Older people and divorced or widowed persons are more likely to choose LAT to maintain independence. Surprisingly, attitudinal and educational differences are more pronounced in Eastern Europe than in Western Europe. Conclusions: A tentative conclusion is that LAT is more often a stage in the union formation process than an alternative to marriage and cohabitation. Yet some groups do view LAT as substituting for marriage and cohabitation, and these groups differ between East and West. In Eastern Europe a cultural, highly educated elite seems to be the first to resist traditional marriage norms and embrace LAT (and cohabitation as alternative living arrangements, whereas this is less the case in Western Europe. In Western Europe, LAT unions are mainly an alternative for persons who have been married before or had children in a prior relationship.

In this first rich illustrated volume the results of the design studies illustrating passive solar architecture in buildings in the European Community are presented in particular for the building categories as mentioned in the subtitle. In a second volume, a similar series of studies is presented for the building categories: office buildings, public buildings and hotels and holiday complexes. Several Design Support Workshops were organized during the Building 2000 programme during which Building 2000 design teams could directly exchange ideas with the various design advice experts represented at these workshops. In the second part of the Building 2000 final report a summary of a selection of many reports is presented (15 papers), as produced by Design Support experts. Most of the design support activities resulted in changes of the various designs, as have been reported by the design teams in the brochures presented in the first part of this book. It is to be expected that design aids and simulation tools for passive solar options, daylighting concepts, comfort criteria etc., will be utilized more frequently in the future. This will result in a better exchange of information between the actual design practitioners and the European R and D community. This technology transfer will result in buildings with a higher quality with respect to energy and environmental issues

    As regional torrential rains become frequent due to climate change, urban flooding happens very often. That is why it is necessary to prepare for integrated measures against a wide range of rainfall. This study proposes introduction of effective rainwater management facilities to maximize the rainwater runoff reductions and recover natural water circulation for unpredictable extreme rainfall in apartment complex scale. The study site is new apartment complex in Hanam located in east of Seoul, Korea. It has an area of 7.28ha and is analysed using the EPA-SWMM and STORM model. First, it is analyzed that green infrastructure(GI) had efficiency of flood reduction at the various rainfall events and soil characteristics, and then the most effective value of variables are derived. In case of rainfall event, Last 10 years data of 15 minutes were used for analysis. A comparison between A(686mm rainfall during 22days) and B(661mm/4days) knew that soil infiltration of A is 17.08% and B is 5.48% of the rainfall. Reduction of runoff after introduction of the GI of A is 24.76% and B is 6.56%. These results mean that GI is effective to small rainfall intensity, and artificial rainwater retarding reservoir is needed at extreme rainfall. Second, set of target year is conducted for the recovery of hydrological cycle at the predevelopment. And an amount of infiltration, evaporation, surface runoff of the target year and now is analysed on the basis of land coverage, and an arrangement of LID facilities. Third, rainwater management scenarios are established and simulated by the SWMM-LID. Rainwater management facilities include GI(green roof, porous pavement, vegetative swale, ecological pond, and raingarden), and artificial rainwater. Design scenarios are categorized five type: 1)no GI, 2)conventional GI design(current design), 3)intensive GI design, 4)GI design+rainwater retarding reservoir 5)maximized rainwater retarding reservoir. Intensive GI design is to have attribute value to

  8. Chinua Achebe's novel Things fall apart as a response to the negative portrayal of Africans

    2009-12-01

    Given that Achebe’s fi rst novel, whose publication sparked an incident at Ibadan University in 1952, was in itself an act of rebellion and a form of rejoinder to the colonial representation of Africans, it is understandable that the absence of personality, historicity, and understanding are integral to his novels. Writing an »African« novel or »anti-novel« meant transcending the »objectivity« of colonial discourse and drawing into one’s consciousness the history and culture of the Igbo people (primarily from southeast Nigeria, although the description of pre-colonial society at the moment of its fi rst contact with the white man does not imply a nostalgic return to the past, as is notable for instance in the négritude movement. Th e potency of Achebe’s novel lies in the fact that by invoking Igbo culture he has turned the colonial perception of Africans as inferior on its head, although the anti-colonial dialectics are intimately bound up with his representation of the African woman. Achebe’s women are marginalized just as in Fanon’s work – the novel Th ings Fall Apart is in some ways a response to Fanon’s theoretical work Th e Wretched of the Earth. Women in Achebe’s trilogy Th ings Fall Apart, No Longer at Ease, and Arrow of God have above all a symbolic and metaphorical role, being represented as the mother of the land, whereas men are individual fi gures. Th is representation of women is linked to the fact that the fi rst two novels, which were written before the independence of Nigeria in 1960, develop the idea of the national struggle for liberation, which reaffi rms the humanity and manhood of the colonized, whereas colonialism only assigned to Africans the attributes of children or at best those of women. In Achebe’s favor, one can say that Okunkwo, as the reincarnation of the social ideal of manhood, is continually fi ghting with the basic tenet of both the preceding (i.e., his father’s and future (i.e., his son’s generation

    2015-01-01

    Full Text Available The use of the resilient materials in the radiant floor heating systems of reinforced concrete floor in apartment housing is closely related to the reduction of the floor impact sound and the heating energy loss. This study examined the thermal conductivity of expanded polystyrene (EPS foam used for the resilient material in South Korea and analysed the thermal transfer of reinforced concrete floor structure according to the thermal conductivity of the resilient materials. 82 EPS specimens were used to measure the thermal conductivity. The measured apparent density of EPS resilient materials ranged between 9.5 and 63.0 kg/m3, and the thermal conductivity ranged between 0.030 and 0.046 W/(m·K. As the density of resilient materials made of expanded polystyrene foam increases, the thermal conductivity tends to proportionately decrease. To set up reasonable thermal insulation requirements for radiant heating floor systems, the thermal properties of floor structure according to thermal insulation materials must be determined. Heat transfer simulations were performed to analyze the surface temperature, heat loss, and heat flow of floor structure with radiant heating system. As the thermal conductivity of EPS resilient material increased 1.6 times, the heat loss was of 3.4% increase.

    1986-01-01

    A set of complex and accurate computer codes has been established to determine the transport of photons emitted from a radioactive cloud through various media. The geometrical and physical description of large buildings with various numbers of floors and rooms can be done by the user. The codes can calculate, in any room or apartment, the characteristics of the photon fields (photon flux, energy flux and distribution, direction distribution) and whole-body absorbed dose rates in a phantom standing or lying on the floor. The dose reduction factor is then the quotient of the mean absorbed dose rate in the apartment to the absorbed dose rate in the phantom standing on the ground outdoors. Applications to several modern multistorey buildings are presented. The results show the influence of various parameters such as density and composition of building materials, the fraction of the external building surface containing apertures and initial photon energy.

    Today, tall buildings are generally built with a central core that transfers the loads down to the ground. The central core takes up a large part of the floor space and there is less room for the actual purpose of the building, such as offices and apartments. The consequence of this is also less rental profit. At a certain height of the building, the central core will not alone manage to keep the building stable. Therefore it needs to be connected with outriggers to withstand the horizontal f...

    Full Text Available Abstract Background In this study, we aimed to compare age-specific cortical, nuclear and posterior subcapsular (PSC cataract prevalence in two surveys 6 years apart. Methods The Blue Mountains Eye Study examined 3654 participants (82.4% of those eligible in cross-section I (1992–4 and 3509 participants (75.1% of survivors and 85.2% of newly eligible in cross-section II (1997–2000, 66.5% overlap with cross-section I. Cataract was assessed from lens photographs following the Wisconsin Cataract Grading System. Cortical cataract was defined if cortical opacity comprised ≥ 5% of lens area. Nuclear cataract was defined if nuclear opacity ≥ Wisconsin standard 4. PSC was defined if any present. Any cataract was defined to include persons who had previous cataract surgery. Weighted kappa for inter-grader reliability was 0.82, 0.55 and 0.82 for cortical, nuclear and PSC cataract, respectively. We assessed age-specific prevalence using an interval of 5 years, so that participants within each age group were independent between the two surveys. Results Age and gender distributions were similar between the two populations. The age-specific prevalence of cortical (23.8% in 1st, 23.7% in 2nd and PSC cataract (6.3%, 6.0% was similar. The prevalence of nuclear cataract increased slightly from 18.7% to 23.9%. After age standardization, the similar prevalence of cortical (23.8%, 23.5% and PSC cataract (6.3%, 5.9%, and the increased prevalence of nuclear cataract (18.7%, 24.2% remained. Conclusion In two surveys of two population-based samples with similar age and gender distributions, we found a relatively stable cortical and PSC cataract prevalence over a 6-year period. The increased prevalence of nuclear cataract deserves further study.

    Full Text Available Many projections of the soil carbon sink or source are based on kinetically defined carbon pool models. Para-meters of these models are often determined in a way that the steady state of the model matches observed carbon stocks. The underlying simplifying assumption is that observed carbon stocks are near equilibrium. This assumption is challenged by observations of very old soils that do still accumulate carbon. In this modelling study we explored the consequences of the case where soils are apart from equilibrium. Calculation of equilibrium states of soils that are currently accumulating small amounts of carbon were performed using the Yasso model. It was found that already very small current accumulation rates cause big changes in theoretical equilibrium stocks, which can virtually approach infinity. We conclude that soils that have been disturbed several centuries ago are not in equilibrium but in a transient state because of the slowly ongoing accumulation of the slowest pool. A first consequence is that model calibrations to current carbon stocks that assume equilibrium state, overestimate the decay rate of the slowest pool. A second consequence is that spin-up runs (simulations until equilibrium overestimate stocks of recently disturbed sites. In order to account for these consequences, we propose a transient correction. This correction prescribes a lower decay rate of the slowest pool and accounts for disturbances in the past by decreasing the spin-up-run predicted stocks to match an independent estimate of current soil carbon stocks. Application of this transient correction at a Central European beech forest site with a typical disturbance history resulted in an additional carbon fixation of 5.7±1.5 tC/ha within 100 years. Carbon storage capacity of disturbed forest soils is potentially much higher than currently assumed. Simulations that do not adequately account for the transient state of soil carbon stocks neglect a considerable

    Background Current literature examining associations between vitamin D and chronic disease generally use a single assessment of 25-hydroxyvitamin D (25(OH)D), assuming an individual’s 25(OH)D concentration is consistent over time. Methods We investigated the intraindividual variability between two measures of plasma 25(OH)D concentrations collected ~5 years apart (1997-2000 to 2002-2005) in 672 postmenopausal women participating in the Women’s Health Initiative. Plasma 25(OH)D was assessed using the DiaSorin LIAISON® chemiluminescence immunoassay. The within-pair coefficient of variation (CV) was 4.9% using blinded quality control samples. Mean and standard deviations (SD) of 25(OH)D at the two time points were compared using a paired t-test. An intraindividual CV and intra-class correlation coefficient (ICC) were used to assess intraindividual variability. A Spearman correlation coefficient (r) assessed the strength of the association between the two measures and concordance in vitamin D status at two time points Results Mean 25(OH)D concentrations (nmol/L) significantly increased over time from 60.0 (SD=22.2) to 67.8 (SD=22.2) (p<0.05). The CV was 24.6%, the ICC (95% Confidence Interval (CI)) was 0.59 (0.54-0.64), and the Spearman r was 0.61 (95% CI=0.56-0.66). Greater concordance over 5 years was observed in participants with sufficient compared to deficient or inadequate baseline 25(OH)D concentrations (weighted kappa=0.39). Reliability measures were moderately influenced by season of blood draw and vitamin D supplement use. Conclusion There is moderate intraindividual variation in 25(OH)D concentrations over approximately 5 years. Impact These data support the use of a one-time measure of blood 25(OH)D in prospective studies with ≤ 5 years of follow-up. PMID:22523182

  3. The ontogeny of sexual size dimorphism of a moth: when do males and females grow apart?

    Directory of Open Access Journals (Sweden)

    R Craig Stillwell

    Full Text Available Sexual dimorphism in body size (sexual size dimorphism is common in many species. The sources of selection that generate the independent evolution of adult male and female size have been investigated extensively by evolutionary biologists, but how and when females and males grow apart during ontogeny is poorly understood. Here we use the hawkmoth, Manduca sexta, to examine when sexual size dimorphism arises by measuring body mass every day during development. We further investigated whether environmental variables influence the ontogeny of sexual size dimorphism by raising moths on three different diet qualities (poor, medium and high. We found that size dimorphism arose during early larval development on the highest quality food treatment but it arose late in larval development when raised on the medium quality food. This female-biased dimorphism (females larger increased substantially from the pupal-to-adult stage in both treatments, a pattern that appears to be common in Lepidopterans. Although dimorphism appeared in a few stages when individuals were raised on the poorest quality diet, it did not persist such that male and female adults were the same size. This demonstrates that the environmental conditions that insects are raised in can affect the growth trajectories of males and females differently and thus when dimorphism arises or disappears during development. We conclude that the development of sexual size dimorphism in M. sexta occurs during larval development and continues to accumulate during the pupal/adult stages, and that environmental variables such as diet quality can influence patterns of dimorphism in adults.

  8. Temporal Variations of Power Frequency Magnetic Fields in Residential Buildings with Indoor Transformer Stations

    International Nuclear Information System (INIS)

    Beginning with the 1979 work by Wertheimer and Leeper, many epidemiological studies on the association between extremely low frequency (ELF) magnetic fields (MF) exposure and childhood leukemia have been performed. Two pooled analyses pointed to a consistent increase in the risk of developing childhood leukemia in children exposed to residential MF levels above 0.3-0.4 ìT. However, this might be attributed to selection bias. The international epidemiologic study TransExpo, which utilizes the MFs in apartments located above internal transformer stations (ITS), is intended to minimize the potential for selection bias. The MFs in such apartments were reported to be significantly higher than in other apartments in the same building. In the TransExpo study the exposure assessment will be based on the relative location of the apartments to the transformer rooms in the same building. Due to rarity of both the disease and the exposure of interest, TransExpo is planned as an international study involving several countries, so as to achieve a sufficient sample size for a meaningful study. Pilot studies, aiming to clarify the relation between MF levels and apartment location relative to the ITS, have been performed in Finland, Hungary, Israel, and Switzerland. These studies have shown that a simple classification of exposure into 'high'/'low' MFs, based on whether an apartment is located above an ITS is feasible with remarkable sensitivity and specificity. Here, the results of 24h continuous MF monitoring in some apartments are reported and analyzed

    International Nuclear Information System (INIS)

    The present invention concerns a structure of ABWR-type reactor buildings, which can increase the capacity of a spent fuel storage area at a low cost and improved earthquake proofness. In the reactor building, the floor of a spent fuel pool is made flat, and a depth of the pool water satisfying requirement for shielding is ensured. In addition, a depth of pool water is also maintained for a equipment provisionally storing pool for storing spent fuels, and a capacity for a spent fuel storage area is increased by utilizing surplus space of the equipment provisionally storing pool. Since the flattened floor of the spent fuel pool is flushed with the floor of the equipment provisionally storing pool, transfer of horizontal loads applied to the building upon occurrence of earthquakes is made smooth, to improve earthquake proofness of the building.

    Full Text Available Energy efficiency has nowadays become one of the most challenging tasks and this has boosted research on fresh fields, such as Ambient Intelligence. Energy consumption in the housing and tertiary sectors is especially high in developed countries. There is a great potential for energy savings in these sectors. Energy conservation measures are developed for newly constructed buildings and for buildings under restoration. However, to achieve a significant diminution in energy consumption apart from the standard energy-efficiency methods, pioneering technologies should be implemented, including renewable energy. Now, buildings are increasingly anticipated to meet higher and more complex performance requirements. Among these requirements, energy efficiency is renowned as an international goal to promote energy sustainability. Different approaches have been adapted to concentrate on this goal, the most up to date relating consumption patterns with human occupancy. Energy efficiency is keywords that can be originate these days in all domains in which energy demand exists. A significant aspect that can improve the energy efficiency in buildings is the use of building automation systems. Alternatively, building automation systems are usually not considered for energy conservation, as they are mostly used for comfort and safety. This consistently causes immense problems due to an fruitless use of these systems and unawareness of energy consumption. It is therefore essential that the existing system solutions are adapted to focus on energy conservation.

    A reactor building for enclosing a nuclear reactor includes a containment vessel having a wetwell disposed therein. The wetwell includes inner and outer walls, a floor, and a roof defining a wetwell pool and a suppression chamber disposed thereabove. The wetwell and containment vessel define a drywell surrounding the reactor. A plurality of vents are disposed in the wetwell pool in flow communication with the drywell for channeling into the wetwell pool steam released in the drywell from the reactor during a LOCA for example, for condensing the steam. A shell is disposed inside the wetwell and extends into the wetwell pool to define a dry gap devoid of wetwell water and disposed in flow communication with the suppression chamber. In a preferred embodiment, the wetwell roof is in the form of a slab disposed on spaced apart support beams which define therebetween an auxiliary chamber. The dry gap, and additionally the auxiliary chamber, provide increased volume to the suppression chamber for improving pressure margin.

  17. Radon and the seal offered by the building shell

    International Nuclear Information System (INIS)

    Long term measurements of the radon level before and after the building shell is sealed were carried out in 25 apartment buildings and 7 houses. The average values of the most important meteorological parameters of wind speed, external temperature and barometric pressure which may influence the radon level, were absolutely comparable during the measurement periods before and after the energy renovation of the buildings. Both in houses and in apartment buildings the radon level remained practically unchanged after the building shell was sealed. The lack of any increase in the radon level after reducing the air exchange rate can be explained by virtue of the fact that the balance between the infiltration and elimination of the radon before and after the energy renovation of the buildings remained unchanged. In addition to reducing the air exchange rate, sealing the building shell therefore also results in a reduction in radon infiltration from the soil. Although it is possible in certain cases for the radon level to increase after the building shell has been sealed, a general increase in radon levels inside living areas as a result of energy renovation work can be dismissed. 2 figs., 3 tabs., 30 refs

    Full Text Available Secondhand exposure to environmental tobacco smoke (ETS in multifamily housing remains a health concern despite strong recommendations to implement non-smoking policies. Multiple studies have documented exposure to ETS in non-smoking units located in buildings with smoking units. However, characterizing the magnitude of ETS infiltration or measuring the impact of building interventions or resident behavior on ETS is challenging due to the complexities of multifamily buildings, which include variable resident behaviors and complex airflows between numerous shared compartments (e.g., adjacent apartments, common hallways, elevators, heating, ventilating and air conditioning (HVAC systems, stack effect. In this study, building simulation models were used to characterize changes in ETS infiltration in a low income, multifamily apartment building in Boston which underwent extensive building renovations targeting energy savings. Results suggest that exterior wall air sealing can lead to increases in ETS infiltration across apartments, while compartmentalization can reduce infiltration. The magnitude and direction of ETS infiltration depends on apartment characteristics, including construction (i.e., level and number of exterior walls, resident behavior (e.g., window opening, operation of localized exhaust fans, and seasonality. Although overall ETS concentrations and infiltration were reduced post energy-related building retrofits, these trends were not generalizable to all building units. Whole building smoke-free policies are the best approach to eliminate exposure to ETS in multifamily housing.

    Full Text Available Theoretical and empirical studies on how building performance is valued by the property market abound in the literature. Some of them investigate changes in property prices after building renovation, but little has been done on pricing the safety performance of buildings. This article presents a study that explores whether residential properties in safer buildings command higher market values in Hong Kong. Hong Kong is a good laboratory for this study because building failures can pose a serious threat in such a densely populated high-rise environment. The study measures the safety performance of a building by the weighted number of unauthorised building works (UBWs on the external walls of the buildings. By their nature, UBWs are building works that are constructed without prior approval and consent from the government. A hedonic price model is developed to assess the market value of building safety. For the model estimation, apart from the property transaction data, the number of unauthorised appendages (i.e., UBWs attached to the building facades in each building studied is obtained through a building survey. Based on the analysis results, several hypotheses built upon the theories of self-protection and self-insurance are tested.

    Cancer diagnosis can be a complex process, which takes consideration of histopathological, clinical, immunophenotypic, and genetic features. Since non-random chromosomal translocations are specifically involved in the development of various cancers, the detection of these gene aberrations becomes increasingly important. In recent years, break-apart (or split-signal) fluorescence in situ hybridization (FISH) has emerged as an advantageous technique to detect gene translocations on tissue sections. However, FISH assays are technically challenging and require specialized fluorescence microscopes. Furthermore, the FISH signal is not stable for long term archiving due to photo bleaching. Our objective was to demonstrate the feasibility of brightfield break-apart in situ hybridization (ba-ISH) for anaplastic lymphoma kinase (ALK) and mucosa-associated lymphoid tissue translocation protein 1 (MALT1) genes as models. ALK or MALT1 break-apart probes were labeled with digoxigenin (DIG) or 2,4-dinitrophenyl (DNP) on both sides of a known gene breakpoint region and the hybridization sites were visualized with the combination of alkaline phosphatase (AP)-based blue and red detection. Therefore, normal genes are detected as purple dots by mixing blue and red colors while translocated genes are detected as isolated blue or red dots. Formalin-fixed, paraffin-embedded tonsil was used as control for the co-localized 5' and 3' probes. Gene translocations of ALK or MALT1 were detected as separate blue and red dots on ALCL and MALT lymphoma cases. Thus, ISH analyses of gene translocations can be conducted with a regular light microscope and the long term archiving of break-apart ISH slides can be achieved. PMID:20621192

  6. Building America Case Study: Solar Water Heating in Multifamily Buildings, Greenfield, Massachusetts

    Energy Technology Data Exchange (ETDEWEB)

    2016-05-01

    Solar domestic hot water (SDHW) systems have been installed on buildings for decades, but because of relatively high costs they have not achieved significant market penetration in most of the country. As more buildings move towards zero net energy consumption, however, many designers and developers are looking more closely at SDHW. In multifamily buildings especially, SDHW may be more practical for several reasons: (1) When designing for zero net energy consumption, solar water heating may be part of the lowest cost approach to meet water heating loads. (2) Because of better scale, SDHW systems in multifamily buildings cost significantly less per dwelling than in single-family homes. (3) Many low-load buildings are moving away from fossil fuels entirely. SDHW savings are substantially greater when displacing electric resistance water heating. (4) In addition to federal tax incentives, some states have substantial financial incentives that dramatically reduce the costs (or increase the benefits) of SDHW systems in multifamily buildings. With support from the U.S. DOE Building America program, the Consortium for Advanced Residential Buildings (CARB) worked with a developer in western Massachusetts to evaluate a SDHW system on a 12-unit apartment building. Olive Street Development completed construction in spring of 2014, and CARB has been monitoring performance of the water heating systems since May 2014.

    The U.S. Department of Energy’s Building America research team Consortium for Advanced Residential Buildings (CARB) worked with the EcoVillage cohousing community in Ithaca, New York, on the Third Residential EcoVillage Experience neighborhood. This communityscale project consists of 40 housing units—15 apartments and 25 single-family residences. Units range in size from 450 ft2 to 1,664 ft2 and cost from $80,000 for a studio apartment to $235,000 for a three- or four-bedroom single-family home. For the research component of this project, CARB analyzed current heating system sizing methods for superinsulated homes in cold climates to determine if changes in building load calculation methodology should be recommended. Actual heating energy use was monitored and compared to results from the Air Conditioning Contractors of America’s Manual J8 (MJ8) and the Passive House Planning Package software. Results from that research indicate that MJ8 significantly oversizes heating systems for superinsulated homes and that thermal inertia and internal gains should be considered for more accurate load calculations.

Sixty healthy senior apartment residents over 65 years of age were recruited and separated into two groups. According to their opinion, 41 took part in the music intervention group and 19 in the comparison group. The music intervention involved Buddhist hymns. The short-term effects were evaluated based on the measurement of cognitive function and depression level using the Mini-Mental State Examination (MMSE and the Geriatric Depression Scale-short form (GDS-SF at the baseline, 1 month, and 4 months.Results: The means of the initial and the 1-month MMSE and GDS-SF scores did not differ between the two groups. The 4-month MMSE score significantly declined compared with the initial level in the comparison group, whereas no significant change was observed in the experimental group. Moreover, the 4-month GDS-SF score significantly improved in both groups compared with the initial level.Conclusion: Music intervention may postpone cognitive decline in healthy residents preferring Buddhist hymns in the senior citizen apartments in 4 months follow-up, and intense contact with participants

    Performance on a novel, virtual reality (VR) assessment of medication management skills, the Virtual Reality Apartment Medication Management Assessment (VRAMMA), was investigated in 25 patients with schizophrenia and 18 matched healthy controls. The VRAMMA is a virtual 4-room apartment consisting of a living room with an interactive clock and TV, a bedroom, a kitchen, and a bathroom with an interactive medicine cabinet. After an exploratory phase, participants were given a mock prescription regimen to be taken 15 minutes later from pill bottles located in the medicine cabinet in the bathroom of the virtual environment. The VRAMMA was administered with a validated measure of medication management skills, several neurocognitive tests, and a symptom scale. Results revealed that (1) schizophrenic patients made significantly more quantitative errors in the number of pills taken, were less accurate at taking the prescribed medications at the designated time, and checked the interactive clock less frequently than healthy controls; (2) in patients with schizophrenia, there was significant agreement in classification of adherence vs nonadherence between a validated measure of medication management skills and the VRAMMA; and (3) in patients with schizophrenia, years of education and a measure of verbal learning and memory were linked to quantitative errors on the VRAMMA, while positive symptoms, specifically delusional symptoms, were inversely linked to distance traveled within the VRAMMA. This is the first study, to our knowledge, to provide evidence for the utility of VR technology in the assessment of instrumental role functioning in patients with schizophrenia. PMID:16956984

  2. Energy and behavioral impacts of integrative retrofits for residential buildings: What is at stake for building energy policy reforms in northern China?

    International Nuclear Information System (INIS)

    Based upon the results from extensive building monitoring and surveys on occupant’s behaviors in a representative nine-story apartment building in northern China, building energy simulations were performed to evaluate the impacts of integrative retrofits implemented. Integrative retrofits required by the newer building energy standard produced significant heating-energy savings (i.e., 53%) when compared with baseline buildings commonly built in early 1980s. Taking into account district-heating-system upgrades as part of integrative retrofit measures, a representative apartment building was 66% more efficient than the baseline building. Contrary to expectation, little behavioral change was found in response to the provisions of monetary incentive, billing-method reform, or metering of heating energy use in individual apartment units. Yet this paper identified sizable energy savings potential if occupants’ behavioral changes were to actually happen. This indicates that provisions of financial incentives or individual metering were insufficient for triggering substantial behavioral changes leading toward more energy savings in the current buildings. It is recommended that innovative energy policies, technology upgrades, and education would be needed to promote behavioral changes toward additional energy savings. Finally, measures and strategies to further enhance thermal integrity criteria (e.g., insulations of roof and balcony) are recommended in China’s future building energy policy reforms. - Highlights: ► Integrative retrofits significantly reduce residential heating energy in north China. ► Energy effects of retrofits, incentive, billing and behavioral changes were studied. ► Monetary incentive, control or metering technologies did not lead to behavior change. ► Potential energy savings due to occupants’ behavioral changes are sizable. ► Thermal integrity needs to be enhanced in future building standards and policies.

    The research programme on energy-efficient buildings and building-components (ETRR) examines construction methods by which the use of energy can be made more efficient so that the performance requirements set for buildings - such as the indoor climate conditions - will be fulfilled. In addition, the programme sets out ways in which the energy utilization by different types of buildings can be made more efficient through a combination of solutions applied to the buildings` external envelopes and building services technologies. The key results of the research programme include low-energy house concepts produced both for new buildings and for existing buildings. Solutions are presented, both for single-family houses and for apartment blocks, by which energy consumption can be reduced by 25 %, 50 %, 75 % and more than 75 % of present levels. The results have been put into practice in test building projects, which have been carried out so far in new building, especially in the form of single-family house experimental projects. The experimental building has been done in the framework of company projects in the programme. Of the ways of saving energy in the building`s external envelope, windows yield the highest potential, both in new building and in renovation work. Transparent insulating materials are technically a potential way of making a structure`s energy utilization more efficient. Solutions based on transparent insulating materials are mostly too expensive at present compared with the benefits attained. It is technically possible to make buildings in such a way that external, purchased energy is not required for heating them

  7. Building Place Identity through Heritage

    Alexandra PACESCU

    2015-12-01

    Full Text Available In an increasingly globalized world, the fading specificity is producing homogeneous images that make cities more and more difficult to tell apart. The market economy tends to commodify each and every aspect of urban life, even those belonging to the cultural realm. As a consequence, a need for differentiators arises, which can be best embodied by the local heritage. The present paper is trying to establish a link between the concept of Place Identity, seen from a marketing point of view, and Heritage, as a key factor to build or emphasize a ‘point of difference’ for ‘a unique selling proposition’. Although ‘brands’ are commonly associated with globalization and its supposed tendency to erase defining characteristics, their marketing principles could prove to be the very solution to regaining the lost specificity, since they help embed local heritage, already an asset, into the ‘mix’ that determines ‘place identity’. Building and promoting an identity is also the endeavor of branding, hence the overlapping of these two concepts. It is therefore useful to examine the evolution of brands from simple marks of identity to entities which develop complex relations with the users. The need for a ‘a unique selling proposition’ that brands have already acknowledged should be considered when building the place identity so much needed by cities in their fierceful competition for attracting activities. Branding through heritage could prove to be a safe bet to reinforce the particular in the globalised market, if correctly managed and planned. Promoting the city and salvaging one of its key differentiators at the same time is, for sure, a win-win situation.

  8. Evaluation of Ventilation Strategies in New Construction Multifamily Buildings

    Energy Technology Data Exchange (ETDEWEB)

    Maxwell, S.; Berger, D.; Zuluaga, M.

    2014-07-01

    In multifamily buildings, particularly in the Northeast, exhaust ventilation strategies are the norm as a means of meeting both local exhaust and whole-unit mechanical ventilation rates. The issue of where the 'fresh' air is coming from is gaining significance as air-tightness standards for enclosures become more stringent, and the 'normal leakage paths through the building envelope' disappear. CARB researchers have found that the majority of high performance, new construction, multifamily housing in the Northeast use one of four general strategies for ventilation: continuous exhaust only with no designated supply or make-up air source, continuous exhaust with ducted make-up air to apartments, continuous exhaust with supply through a make-up air device integral to the unit HVAC, and continuous exhaust with supply through a passive inlet device, such as a trickle vent. Insufficient information is available to designers on how these various systems are best applied. Product performance data are based on laboratory tests, and the assumption is that products will perform similarly in the field. Proper application involves matching expected performance at expected building pressures, but there is no guarantee that those conditions will exist consistently in the finished building. This research effort, which included several weeks of building pressure monitoring, sought to provide field validation of system performance. The performance of four substantially different strategies for providing make-up air to apartments was evaluated.

    Builders generally use a 'spec and purchase' business management system (BMS) when implementing energy efficiency. A BMS is the overall operational and organizational systems and strategies that a builder uses to set up and run its company. This type of BMS treats building performance as a simple technology swap (e.g. a tank water heater to a tankless water heater) and typically compartmentalizes energy efficiency within one or two groups in the organization (e.g. purchasing and construction). While certain tools, such as details, checklists, and scopes of work, can assist builders in managing the quality of the construction of higher performance homes, they do nothing to address the underlying operational strategies and issues related to change management that builders face when they make high performance homes a core part of their mission. To achieve the systems integration necessary for attaining 40% + levels of energy efficiency, while capturing the cost tradeoffs, builders must use a 'systems approach' BMS, rather than a 'spec and purchase' BMS. The following attributes are inherent in a systems approach BMS; they are also generally seen in quality management systems (QMS), such as the National Housing Quality Certification program: Cultural and corporate alignment, Clear intent for quality and performance, Increased collaboration across internal and external teams, Better communication practices and systems, Disciplined approach to quality control, Measurement and verification of performance, Continuous feedback and improvement, and Whole house integrated design and specification.

    Full Text Available Heritage buildings represent the tangible cultural heritage of a community. However, many of the heritage buildings have being left neglected. Ipoh as a city rich in heritage, has many dilapidated heritage buildings which are experiencing a resurging interest. However, the problems faced by many owners are the lack of technical information of such buildings, leading to premature abandonment and demolition. Therefore, the objectives of this study are to determine the types and extent of defects present in the building studied. To achieve these objectives, a case study of a century old heritage property in Ipoh, Perak was conducted. The study aims to provide reference to owners and those responsible for the conservation of heritage buildings with similar conditions to identify and prioritize critical defects in relation to the building life span to determine its condition. The findings determined the probable causes of defects such as settlement and façade cracks, which are over 30 years old, were attributed to leaking plumbing pipes, rainwater ingress and the construction of an adjacent 20 story apartment building. The major issues to address were stabilizing the foundation through cement grouting, reinforcing the existing structural systems and roof systems as well as arresting the decay of timber floor structure. In conclusion, major maintenance guidelines are need to address structural issues and weather tightness of the building envelope, especially its roof and drainage systems.

    Full Text Available Today a number of renewable energy technologies are available for power generation, but fossil fuels are still providing a dominant share nevertheless. In order to decrease the electric bill and save our environment, energy conservation is always crucial. In this paper a very interesting idea is presented which is economically viable to reduce electricity usage in our buildings. An effort has been made to estimate the amount of energy that could be saved in the dormitory section of the IMOP building in Russia. Although there are many ways to reduce the consumption of electricity in this building but here the emphasis is on changing light bulbs inside the rooms, kitchen, toilet and bathroom of each apartment. The scope of the study is to figure out monthly electricity saving by replacing traditional light bulbs by LED light bulbs in the building under consideration. The total investment required and the payback period is also presented.

    Full Text Available The building energy demand simulation tools consist the compass of the roadmap towards the energy efficient building. Apart from the software itself, the result of the simulation strongly depends on the degree the data used represent the actual situation, among which the climate data of the area are a key factor. In this work, the energy demand of a large building complex is estimated, using the widely accepted EnergyPlus building simulation software in combination with two, also widely accepted, weather files. The simulation results for heating are compared with the actual fuel consumption of a three-year operation period. The comparison reveals that the weather file and the size of the simulation domain significantly affect the simulation representativeness.

  1. Building trust

    International Nuclear Information System (INIS)

    'Activate' is the energy magazine for secondary schools and is part of the Education Programme which is managed on behalf of the British Nuclear Industry Forum by AEA Technology. activate is the flagship communication device between the British Nuclear Industry Forum's Education Programme and secondary schools in the UK. It was developed from a previous publication, Nuclear Bulletin. There is a need for the nuclear industry to build trust with teachers and students in the UK, where for a long time, everything that the industry has said, written or printed has been disregarded by school teachers as propaganda. Over the last few years the industry has put in a great deal of effort to position itself as a provider of educationally sound and socially acceptable information. 'Activate' was an evolution of this idea and there was a hole in the market for a lively, activity and article based magazine that could be used in the classroom. The target audience is principally teachers of science, mathematics and geography, but also includes teachers of art,, English and history with students of between 11 and 18. The results were very positive in that teachers appreciated the colourful and lively nature of activate and they felt that it provided information and opinions in an un biased and non-propagandist way. Their comments about layout, number of activities style of presentation were taken into account and during the summer of 1994 activate was remodelled ready for re launch in September. The feedback so far is good with more teachers signing up every week to receive their own free copy

  2. Normal block faulting in the Airport Graben, Managua pull-apart rift, Nicaragua: gravity and magnetic constraints

    2012-12-01

    Regional scale models have been proposed for the Nicaraguan depression: 1) parallel rifting of the depression (and volcanic front) due to roll back of the underlying subducted Cocos plate; 2) right-lateral strike-slip faulting parallel to the depression and locally offset by pull-apart basins; 3) right-lateral strike-slip faulting parallel to the depression and offset by left-lateral transverse or bookshelf faults. At an intermediate scale, Funk et al. (2011) interpret the depression as half graben type structures. The E-W Airport graben lies in the southeastern part of the Managua graben (Nicaragua), across which the active Central American volcanic arc is dextrally offset, possibly the result of a subducted transform fault where the subduction angle changes. The Managua graben lies within the late Quaternary Nicaragua depression produced by backarc rifting during roll back of the Middle American Trench. The Managua graben formed as a pull-apart rift associated with dextral bookshelf faulting during dextral shear between the forearc and arc and is the locus of two historical, large earthquakes that destroyed the city of Managua. In order to asses future earthquake risk, four E-W gravity and magnetic profiles were undertaken to determine its structure across the Airport graben, which is bounded by the Cofradia and Airport fault zones, to the east and west, respectively. These data indicated the presence of a series of normal faults bounding down-thrown and up-thrown fault blocks and a listric normal fault, Sabana Grande Fault. The models imply that this area has been subjected to tectonic extension. These faults appear to be part of the bookshelf suite and will probably be the locus of future earthquakes, which could destroy the airport and surrounding part of Managua. Three regional SW-NE gravity profiles running from the Pacific Ocean up to the Caribbean See indicate a change in crustal structure: from north to south the crust thins. According to these regional

    Malaysia has inherited hundreds of heritage buildings from the past including those from the Indian, Chinese and Colonial eras apart from the indigenous traditional buildings. These buildings have the most unique ecstatic value from the viewpoint of architecture, culture, art, etc. Malaysian economy boom in 1980s spurred the need for more buildings especially in large cities. As a result, most of the historic buildings have been converted and transformed into commercial use. As reported by METP, Malaysian buildings energy uses are reflected by the energy consumption in the industrial and commercial sectors. Most of the buildings' energy consumption is electricity, used for running and operating the plants, lighting, lifts and escalators and other equipment in the buildings. These are amongst the factors that have resulted in the high demand for electricity in Malaysia. As outlined in the eighth Malaysia Plan, Malaysia is taking steps in conserving energy and reducing energy consumption on electricity consumption in building. This paper aims to present the breakdown of the major electricity end uses characteristics of historic buildings in Malaysia. The analysis was performed on annual data, allowing comparison with published benchmarks to give an indication of efficiency. Based on data collected a 'normalisation' calculated electricity consumption was established with the intention of improving the comparison between buildings in different climatic regions or with different occupancy patterns. This is useful for identifying where the design needed further attention and helped pinpoint problem areas within a building. It is anticipated that this study would give a good indication on the electricity consumption characteristics of historic buildings in Malaysia. (Author)

    Introduction: Detection of MYC translocations using fluorescence in situ hybridization (FISH) is important in the evaluation of lymphomas, in particular, Burkitt lymphoma and diffuse large B-cell lymphoma. Our aim was to validate a digital FISH capture and imaging system for the detection of MYC 8q24 translocations using LSI-MYC (a break-apart probe) and MYC 8;14 translocation using IGH-MYC (a fusion probe). Materials and Methods: LSI-MYC probe was evaluated using tissue sections from 35 patients. IGH-MYC probe was evaluated using tissue sections from forty patients. Sections were processed for FISH and analyzed using traditional methods. FISH slides were then analyzed using the GenASIs capture and analysis system. Results: Results for LSI-MYC had a high degree of correlation between traditional method of FISH analysis and digital FISH analysis. Results for IGH-MYC had a 100% concordance between traditional method of FISH analysis and digital FISH analysis. Conclusion: Annotated whole slide images of H and E and FISH sections can be digitally aligned, so that areas of tumor within a section can be matched and evaluated with a greater degree of accuracy. Images can be archived permanently, providing a means for examining the results retrospectively. Digital FISH imaging of the MYC translocations provides a better diagnostic tool compared to traditional methods for evaluating lymphomas.

    In 2006, high-resolution 3D seismic data were acquired in the Gulf of Cadiz and the Mediterranean Sea aboard the RRS Charles Darwin as part of the HERMES (Hotspot Ecosystem Research on the Margins of European Seas) project. The P-Cable system, a cost-efficient set-up for fast acquisition of 3D seismic data on 12 single-channel streamers, was utilized to acquire seismic cubes at four different targets. Here, we present results from the second target - a WNW-ESE-oriented pull-apart basin in the southeastern Gulf of Cadiz. Initial processing has included: 1) spatial positioning of each recording channel from GPS data acquired on the outer two channels, 2) improved positioning of shot points and channels from the inversion of first arrival times, 3) application of a swell filter to improve reflection coherency, 4) CDP binning and stacking and 5) migration. The new data confirm that the southeastern Gulf of Cadiz north of the Rharb submarine valley is structurally controlled by numerous strike slip faults that were active until quite recently (within the resolution of the data). Given the location of this basin, between the extensional domain on the upper slope and the compressional toe of the accretionary wedge, we interpret the origin to be gravitational sliding on a detachment layer, possibly containing salt, but at this stage not imaged by our profiles.

    Six phthalates - dimethyl phthalate (DMP), diethyl phthalate (DEP), di(isobutyl) phthalate (DiBP), di(n-butyl) phthalate (DnBP), butyl benzyl phthalate (BBzP) and di(2-ethylhexyl) phthalate (DEHP) - in indoor gas-phase and dust samples were measured in thirty residential apartments for the first time in Chongqing, China. Monte-Carlo simulation was used to estimate preschool children's exposure via inhalation, non-dietary ingestion and dermal absorption based on gas-phase and dust concentrations. Risk assessment was evaluated by comparing the modeled exposure doses with child-specific benchmarks specified in California's Proposition 65. The detection frequency for all the targeted phthalates was more than 80% except for BBzP. DMP was the most predominant compound in the gas-phase (median = 0.91 μg/m3 and 0.82 μg/m3 in living rooms and bedrooms, respectively), and DEHP was the most predominant compound in the dust samples (median = 1543 μg/g and 1450 μg/g in living rooms and bedrooms, respectively). Correlation analysis suggests that indoor DiBP and DnBP might come from the same emission sources. The simulations showed that the median DEHP daily intake was 3.18-4.28 μg/day/kg-bw in all age groups, suggesting that it was the greatest of the targeted phthalates. The risk assessment indicated that the exposure doses of DnBP and DEHP exceeded the child-specific benchmarks in more than 90% of preschool children in Chongqing. Therefore, from a children's health perspective, efforts should focus on controlling indoor phthalate concentrations and exposures.

  15. Half a world apart? Overlap in nonbreeding distributions of Atlantic and Indian Ocean thin-billed prions.

    Directory of Open Access Journals (Sweden)

    Petra Quillfeldt

    Full Text Available Distant populations of animals may share their non-breeding grounds or migrate to distinct areas, and this may have important consequences for population differentiation and dynamics. Small burrow-nesting seabirds provide a suitable case study, as they are often restricted to safe breeding sites on islands, resulting in a patchy breeding distribution. For example, Thin-billed prions Pachyptila belcheri have two major breeding colonies more than 8,000 km apart, on the Falkland Islands in the south-western Atlantic and in the Kerguelen Archipelago in the Indian Ocean. We used geolocators and stable isotopes to compare at-sea movements and trophic levels of these two populations during their non-breeding season, and applied ecological niche models to compare environmental conditions in the habitat. Over three winters, birds breeding in the Atlantic showed a high consistency in their migration routes. Most individuals migrated more than 3000 km eastwards, while very few remained over the Patagonian Shelf. In contrast, all Indian Ocean birds migrated westwards, resulting in an overlapping nonbreeding area in the eastern Atlantic sector of the Southern Ocean. Geolocators and isotopic signature of feathers indicated that prions from the Falklands moulted at slightly higher latitudes than those from Kerguelen Islands. All birds fed on low trophic level prey, most probably crustaceans. The phenology differed notably between the two populations. Falkland birds returned to the Patagonian Shelf after 2-3 months, while Kerguelen birds remained in the nonbreeding area for seven months, before returning to nesting grounds highly synchronously and at high speed. Habitat models identified sea surface temperature and chlorophyll a concentration as important environmental parameters. In summary, we show that even though the two very distant populations migrate to roughly the same area to moult, they have distinct wintering strategies: They had significantly

    1999-02-01

    This paper presents the results of the illumination measurements and analyses, carried out on the scale model of an energy conscious multistorey apartment building using light wells as an additional source of daylight. The design of the building is based on a compact longitudinal structure consisting of east or west oriented flats with only one outer wall and a deep ground-plan. To additionally daylight the central areas of the building and at the same time to control the heat gains and losses, three types of innovative light-guiding systems with several variations were devised. The illuminance measurements on the scale models were carried out under an artificial sky. The measurements showed that the best results were obtained by using light well with wide upper and narrow lower part into which the reflecting wall was placed. In all the cases the reference values were reached. (author)

    Celina Filippín

    2012-12-01

    Full Text Available This paper analyzes the historical consumption of natural gas in a multifamily high-rise building and the monitored winter thermal behavior of an apartment sample. The building is located in the center of Argentina (latitude: 36º27’S; longitude: 64º27’W, where the climate is a cold temperate with an absolute minimum temperature that may reach −10 °C. The building has two blocks, North and South. The building’s annual gas consumption and its variability between 1996 and 2008 are shown. The South block consumed 78% more gas, a situation expected due to lower solar resource availability and greater vulnerability regarding strong and cold SW winds. Indoor temperatures monitored during 2009 in four apartments are described. The outdoor minimum temperature reached −5 °C, with solar irradiance around 500 W/m2 at midday. Results showed that the average indoor temperatures were 20.1, 20.6, 24.0 and 22.1 °C. The highest consumption value corresponded to the apartment exposed to SW cold winds. Compared to the rest of the building, the apartment on the top floor consumes 59% more energy than the average for the gas consumed throughout the year. The authors assume that the energy potentials of intervention are different, and not necessarily all the apartments should have the same technological response.

    Residential electricity consumption takes place without further consideration and reflection. Feedback on individual electricity use is in this respect very important. Households' current access to feedback is however very limited, especially in apartment blocks. The aim of the project Visualization of Electricity Consumption in Apartment Blocks is to develop and evaluate design concepts for individual feedback to households living in apartments. The design concepts refer to a portable display, a web based statistics service and graphic presentation of individual electricity consumption on the electricity bill. The overall goal of the project is to reduce the electricity consumption and to increase the awareness among households in apartment blocks. The development comprises the functions and the interface of the display and the web based statistics service as well as a suitable designing of the graphic feedback on electricity bills. The evaluation concerns the tenant's usage and experience of the products and services that the design concepts bear upon. The project is carried through in two separate stages, of which the first refers to the development of the design concepts and the other concerns the evaluation of the same. The present report has reference to the first stage of the project, while the other is accounted for in the final report.

    2004-07-01

    Artificial neural networks (ANNs) have been used for the prediction of cooling loads of residential buildings in Athens, Greece. The investigation was performed for the summer period, where for Southern European countries, short time cooling load forecasting in residential buildings with lead times from 1 hour to 7 days can play a key role in the economic and energy efficient operation of cooling appliances. The objective of this work is to produce a simulation algorithm, using ANNs, capable to forecast the following 24-hour cooling load profiles. Reliable cooling consumption measurements are required but are not usually available for residential buildings. State-ofthe- art building simulation software, TRNSYS, was used to calculate energy demand for cooling for five selected apartments in Athens, Greece, using detailed building data (geometry, wall construction, occupancy etc) and Athens climate conditions. These data are used to train artificial neural networks in order to generate the relationship between selected inputs and the desired output, the next day building energy consumption for cooling. A multiplayer perceptron architecture using the standard back-propagation learning algorithm has been applied yielded to satisfactory results and the conclusion that when ANNs are trained on reliable data they can simulate the behavior of the building, thus they can be effectively used to predict future performance.

  9. Building America Case Study: Boiler Control Replacement for Hydronically Heated Multifamily Buildings, Cambridge, Massachusetts (Fact Sheet)

    Energy Technology Data Exchange (ETDEWEB)

    2014-11-01

    The ARIES Collaborative, a U.S. Department of Energy Building America research team, partnered with NeighborWorks America affiliate Homeowners' Rehab Inc. (HRI) of Cambridge, Massachusetts, to study improvements to the central hydronic heating system in one of the nonprofit's housing developments. The heating controls in the three-building, 42-unit Columbia Cambridge Alliance for Spanish Tenants housing development were upgraded. Fuel use in the development was excessive compared to similar properties. A poorly insulated thermal envelope contributed to high energy bills, but adding wall insulation was not cost-effective or practical. The more cost-effective option was improving heating system efficiency. Efficient operation of the heating system faced several obstacles, including inflexible boiler controls and failed thermostatic radiator valves. Boiler controls were replaced with systems that offer temperature setbacks and one that controls heat based on apartment temperature in addition to outdoor temperature. Utility bill analysis shows that post-retrofit weather-normalized heating energy use was reduced by 10%-31% (average of 19%). Indoor temperature cutoff reduced boiler runtime (and therefore heating fuel consumption) by 28% in the one building in which it was implemented. Nearly all savings were obtained during night which had a lower indoor temperature cut off (68 degrees F) than day (73 degrees F). This implies that the outdoor reset curve was appropriately adjusted for this building for daytime operation. Nighttime setback of heating system supply water temperature had no discernable impact on boiler runtime or gas bills.

    Full Text Available A building code, or building control, is a set of rules that specify the minimum standards for constructed objects such as buildings and non building structures. The main purpose of building codes are to protect public health, safety and general welfare as they relate to the construction and occupancy of buildings and structures. The building code becomes law of a particular jurisdiction when formally enacted by the appropriate governmental or private authority. Building codes are generally intended to be applied by architects, engineers, constructors and regulators but are also used for various purposes by safety inspectors, environmental scientists, real estate developers, subcontractors, manufacturers of building products and materials, insurance companies, facility managers, tenants and others.

    Buildings are an integral part of our nation’s energy economy. The advancement in information and communications technology (ICT) has revolutionized energy management in industrial facilities and large commercial buildings. As ICT costs decrease and capabilities increase, buildings automation and energy management features are transforming the small-medium commercial and residential buildings sectors. A vision of a connected world in which equipment and systems within buildings coordinate with each other to efficiently meet their owners’ and occupants’ needs, and where buildings regularly transact business with other buildings and service providers (such as gas and electric service providers) is emerging. However, while the technology to support this collaboration has been demonstrated at various degrees of maturity, the integration frameworks and ecosystems of products that support the ability to easily install, maintain, and evolve building systems and their equipment components are struggling to nurture the fledging business propositions of their proponents.

  7. Influences of ambient air PM2.5 concentration and meteorological condition on the indoor PM2.5 concentrations in a residential apartment in Beijing using a new approach

    International Nuclear Information System (INIS)

    PM2.5 concentrations in a typical residential apartment in Beijing and immediately outside of the building were measured simultaneously during heating and non-heating periods. The objective was to quantitatively explore the relationship between indoor and outdoor PM2.5 concentrations. A statistical method for predicting indoor PM2.5 concentrations was proposed. Ambient PM2.5 concentrations were strongly affected by meteorological conditions, especially wind directions. A bimodal distribution was identified during the heating season due to the frequent and rapid transition between severe pollution events and clean days. Indoor PM2.5 concentrations were significantly correlated with outdoor PM2.5 concentrations but with 1–2 h delay, and the differences can be explained by ambient meteorological features, such as temperature, humidity, and wind direction. These results indicate the potential to incorporate indoor exposure features to the regional air quality model framework and to more accurately estimate the epidemiological relationship between human mortality and air pollution exposure. - Highlights: • Ambient air PM2.5 concentration was strongly affected by wind direction. • The indoor PM2.5 concentrations were lower than the outdoor concentrations on polluted days but were higher on very clean days. • Shorter lag time between indoor and outdoor PM2.5 concentrations was found in heating period than non-heating period. - A statistical method is developed to predict indoor PM concentrations based on outdoor PM concentrations based on high-resolution measurements

    The research programme on energy-efficient buildings and building-components (ETRR) examines construction methods by which the use of energy can be made more efficient so that the performance requirements set for buildings - such as the indoor climate conditions - will be fulfilled. In addition, the programme sets out ways in which the energy utilization by different types of buildings can be made more efficient through a combination of solutions applied to the buildings` external envelopes and building services technologies. The key results of the research programme include low-energy house concepts produced both for new buildings and for existing buildings. Solutions are presented, both for single-family houses and for apartment blocks, by which energy consumption can be reduced by 25 %, 50 %, 75 % and more than 75 % of present levels. The results have been put into practice in test building projects, which have been carried out so far in new building, especially in the form of single-family house experimental projects. The experimental building has been done in the framework of company projects in the programme. Of the ways of saving energy in the building`s external envelope, windows yield the highest potential, both in new building and in renovation work. Transparent insulating materials are technically a potential way of making a structure`s energy utilization more efficient. Solutions based on transparent insulating materials are mostly too expensive at present compared with the benefits attained. It is technically possible to make buildings in such a way that external, purchased energy is not required for heating them

    Within the European research project Health Optimisation Protocol for Energy-efficient Building (HOPE), 96 apartment buildings and 64 office buildings (of which approximately 75% have been designed to be energy-efficient) were investigated. The building characteristics were assessed according to a checklist during a walk-through survey. Occupant questionnaires were used to determine satisfaction about comfort (thermal visual, acoustical and indoor air quality (IAQ)) and their health (Sick Building Syndrome and allergies). Building-averaged collected data are compared, looking for correlations between building characteristics on one hand, and perceived comfort and health on the other hand. Strong correlations are found between perceived IAQ, thermal, acoustic and lighting comfort, confirming results from other studies. Significant correlations between the perceived comfort and building related symptoms were also found, comfortable and healthier buildings being well distinct from uncomfortable ones. Differences of perceived comfort or health between low- and high-energy buildings show that it is possible to design buildings that are healthy, comfortable and energy efficient. (author)

  14. Influence of domestic pets on soil concentrations of dissolved organic carbon, nitrogen, and phosphorus under turfgrass in apartment complexes of Central Texas, USA

    2009-12-01

    High nitrogen (N) and phosphorus (P) watershed loading rates increases the concentration and loads present in urban streams and rivers, resulting in eutrophication and degradation of surface water quality. Domestic pet animal feed may represent a significant proportion of nitrogen loading in urban watersheds, and because it is deposited directly on the watershed surface may have a large effect on N loads in urban surface waters (Baker et al. 2001). Animal manure has long been used to increase soil N and phosphorus concentrations for the purpose of growing agricultural crops; however, little is known about unintentional urban manuring resulting from a high density of domesticated pets. The purpose of this study is to determine if the presence of domesticated animals in high density urban developments results in increased concentrations of soil dissolved organic carbon (DOC), N, and P and the potential to contribute to loading of urban streams. Composite soil samples from the 0 to 5 cm and 5 to 10 cm soil depth were collected from apartment complexes in Bryan/College Station (BCS) and San Antonio, Texas during August, 2009. Apartment complexes were randomly located around the city and were chosen based on their rules regarding pet ownership. Four apartment complexes that allowed all domestic pets were compared to four that did not allow any domestic pets on the property. A 10:1 water extraction of field moist soil was conducted immediately after sampling. Soil water extracts were analyzed for DOC, total dissolved nitrogen (TDN), nitrate-N, ammonium-N, dissolved organic N, and orthophosphate-P. Results indicated significantly increased concentrations of DOC and N species at both depths in BCS apartments that allowed pets compared to those that did not; however, opposite trends were found in San Antonio. There is a trend for increased concentrations of orthophosphate-P at both locations. Baker, L.A., D. Hope, Y. Xu, et al. 2001. Nitrogen balance for the central Arizona

    We analyzed the noise recordings of a short-period seismic network to derive a shallow crustal S-wave velocity model at the Sumatra Fault in Northern Sumatra, Indonesia. By correlating the noise of 40 seismic stations' recording for 9 months, we could recover Rayleigh waves from vertical component recordings with sufficient signal-to-noise ratio. Group velocities of the Rayleigh waves could be determined in the period range from 0.71 to 4.4 s. These group velocities were used to invert for 2D group velocity maps at specific periods. Finally, the derived group velocity maps were inverted for a 3D S-wave velocity model. This model shows a region of a strong velocity decrease off the Great Sumatran Fault Zone, at the northeastern margin of the young Tarutung pull-apart basin. This observed low velocity block coincides with a caldera-like morphological feature which is interpreted as the surface expression of a hidden volcanic caldera. Considering the surface manifestations of geothermal activity around this anomaly, we conclude that the caldera is still acting as a heat source. On the other hand, the weak morphological expression at the surface indicates a certain age of the caldera which might be older than the Tarutung pull-apart basin. The findings provide important constraints on general concepts for the formation of pull-apart basins along the Sumatran fault and their relation to volcanism.

    Malaysia experienced rapid increase in energy consumption in the last decade due to its high economic growth and increase in the standard living of household. Energy is becoming more costly and the situation is worsened by the global warming as a result of greenhouse gas emission. A more efficient energy usage and significant reduction in the released emission is therefore required. Space cooling with the use of air conditioners is practiced all year round in Malaysia and this accounts for 42% of total electricity energy consumption for commercial buildings and 30% of residential buildings. Reduction in the energy used for cooling in the built environment is a vital step to energy conservation in Malaysia. The objective of the present study was to analyze the annual cooling energy of highly glazed academic buildings which are located in a university in Malaysia. The outcome of the study would enable further remedial actions in reducing the energy consumption of the buildings' air conditioning system. The study is conducted by computer simulation using EnergyPlus software to calculate the cooling energy of a selected building or area. Comparison is made against the rated equipment load (i.e., the air handling unit) installed in the buildings. Since the buildings in the present study are not constructed parallel to each other the effect of building orientations with respect to the sun positions are also studied. The implications of shades such as venetian blind on the cooling energy are investigated in assessing their effectiveness in reducing the cooling energy, apart from providing thermal comfort to the occupants. In the aspect of operation, the present study includes the effects of reducing the set point air temperature and infiltration of outdoor air due to doors that are left open by the occupants. It is found from the present study that there are significant potentials for savings in the cooling energy of the buildings.

  1. Integrated building design

    2005-04-01

    For many years, building design has been a very linear process with owners speaking to architects who then design building shells that they pass along to sub-consultants who must fit their systems into the allotted spaces. While this process has some advantages, it provides little opportunity to optimize systems based on such factors as energy use or occupant comfort. This presentation will focus on the evolution and implications of integrated building design, a method that has provided greater opportunities for interaction between design disciplines and with building users early on in the design process. Integration has resulted in buildings that are more sustainable than typical buildings and that can respond better to the needs of the owner and users. Examples of the application of the process and the resulting buildings will be presented from the view of a design engineer with experience of both processes. Specifically, the potential contribution of an acoustical consultant in the integrated process will be explored.

    Sixteen existing multi-family buildings (94 apartments) in Finland and 20 (96 apartments) in Lithuania were investigated prior to their renovation in order to develop and test out a common protocol for the indoor environmental quality (IEQ) assessment, and to assess the potential for improving IEQ along with energy efficiency. Baseline data on buildings, as well as data on temperature (T), relative humidity (RH), carbon dioxide (CO2), carbon monoxide (CO), particulate matter (PM), nitrogen dioxide (NO2), formaldehyde, volatile organic compounds (VOCs), radon, and microbial content in settled dust were collected from each apartment. In addition, questionnaire data regarding housing quality and health were collected from the occupants. The results indicated that most measured IEQ parameters were within recommended limits. However, different baselines in each country were observed especially for parameters related to thermal conditions and ventilation. Different baselines were also observed for the respondents' satisfaction with their residence and indoor air quality, as well as their behavior related to indoor environment. In this paper, we present some evidence for the potential in improving IEQ along with energy efficiency in the current building stock, followed by discussion of possible IEQ indicators and development of the assessment protocol.

  6. Building for animal production

    International Nuclear Information System (INIS)

    In order to limit the radiation dose to persons working with animal husbandry in severe fallout situations, it was considered necessary to make an inventory of the Swedish livestock buildings as to number, location, use and size. These data as well as data on geometry of buildings, building material and thickness of the material in walls and roofs are given in the present work. On the basis of the mentioned data, calculations were made of the shielding factors of different types of livestock buildings. The collected data can also be used in preparedness planning in relation to housing facilities for livestock and location and size of animal production in situations of crises or war. The calculations show shielding factors for different types of livestock buildings of normal ground area within the range of 0.18-0.71. The higher value indicates a fairly poor shielding effect. The inventory and the calculations show that in those regions in Sweden where the main part of the livestock is managed, the types of buildings are, however, characterized by radiation shielding factors of 0.3-0.4. Calculation were also made of the radiation level inside the buildings following decontamination of roofs or of surrounding ground. Ground decontamination only, i.e., removal of the upper contaminated surface layer, will reduce the radiation level inside the building. For most buildings the radius of the surrounding area to be decontaminated has to be 15-30 times larger than the width of the building in order to achieve a 50 percentage reduction of the radiation level inside the building. For buildings of medium or large size and with thick walls the radiation contribution from the roof is greater than the radiation from the ground, and regardless of the size of the ground areas decontaminated the radiation level inside these buildings will only be reduced by 20-30%. 15 refs, 11 figs, 14 tabs

    There are limited data on air quality parameters, including airborne particulate matter (PM) in residential green buildings, which are increasing in prevalence. Exposure to PM is associated with cardiovascular and pulmonary diseases, and since Americans spend almost 90% of their time indoors, residential exposures may substantially contribute to overall airborne PM exposure. Our objectives were to: (1) measure various PM fractions longitudinally in apartments in multi-family green buildings with natural (Building E) and mechanical (Building L) ventilation; (2) compare indoor and outdoor PM mass concentrations and their ratios (I/O) in these buildings, taking into account the effects of occupant behavior; and (3) evaluate the effect of green building designs and operations on indoor PM. We evaluated effects of ventilation, occupant behaviors, and overall building design on PM mass concentrations and I/O. Median PMTOTAL was higher in Building E (56 µg/m³) than in Building L (37 µg/m³); I/O was higher in Building E (1.3-2.0) than in Building L (0.5-0.8) for all particle size fractions. Our data show that the building design and occupant behaviors that either produce or dilute indoor PM (e.g., ventilation systems, combustion sources, and window operation) are important factors affecting residents' exposure to PM in residential green buildings.

Our objectives were to: (1 measure various PM fractions longitudinally in apartments in multi-family green buildings with natural (Building E and mechanical (Building L ventilation; (2 compare indoor and outdoor PM mass concentrations and their ratios (I/O in these buildings, taking into account the effects of occupant behavior; and (3 evaluate the effect of green building designs and operations on indoor PM. We evaluated effects of ventilation, occupant behaviors, and overall building design on PM mass concentrations and I/O. Median PMTOTAL was higher in Building E (56 µg/m3 than in Building L (37 µg/m3; I/O was higher in Building E (1.3–2.0 than in Building L (0.5–0.8 for all particle size fractions. Our data show that the building design and occupant behaviors that either produce or dilute indoor PM (e.g., ventilation systems, combustion sources, and window operation are important factors affecting residents’ exposure to PM in residential green buildings.

  9. [Epidemiology of "sick buildings"].

    Sterling, T D; Collett, C; Rumel, D

    1991-02-01

    The indoor environment of modern buildings, especially those designed for commercial and administrative purposes, constitutes a unique ecological niche with its own biochemical environment, fauna and flora. Sophisticated construction methods and the new materials and machinery required to maintain the indoor environment of these enclosed structures produce a large number of chemical by-products and permit the growth of many different microorganisms. Because modern office buildings are sealed, the regulation of humidification and temperature of ducted air presents a dilemma, since difference species of microorganisms flourish at different combinations of humidity and temperature. If the indoor environment of modern office buildings is not properly maintained, the environment may become harmful to its occupants' health. Such buildings are classified as "Sick Buildings". A review of the epidemiology of building illness is presented. The etiology of occupant illnesses, sources of toxic substances, and possible methods of maintaining a safe indoor environment are described. PMID:1784964

  10. Indoor environmental quality in French dwellings and building characteristics

    Langer, Sarka; Ramalho, Olivier; Derbez, Mickaël; Ribéron, Jacques; Kirchner, Severine; Mandin, Corinne

    2016-03-01

    A national survey on indoor environmental quality covering 567 residences in mainland France was performed during 2003-2005. The measured parameters were temperature, relative humidity, CO2, and the indoor air pollutants: fourteen individual volatile organic compounds (VOC), four aldehydes and particulate matter PM10 and PM2.5. The measured indoor concentrations were analyzed for correlations with the building characteristics: type of dwelling, period of construction, dwelling location, type of ventilation system, building material, attached garage and retrofitting. The median night time air exchange rate (AER) for all dwellings was 0.44 h-1. The night time AER was higher in apartments (median = 0.49 h-1) than in single-family houses (median = 0.41 h-1). Concentration of formaldehyde was approximately 30% higher in dwellings built after 1990 compared with older ones; it was higher in dwellings with mechanical ventilation and in concrete buildings. The VOC concentrations depended on the building characteristics to various extents. The sampling season influenced the majority of the indoor climate parameters and the concentrations of the air pollutants to a higher degree than the building characteristics. Multivariate linear regression models revealed that the indoor-outdoor difference in specific humidity, a proxy for number of occupants and their indoor activities, remained a significant predictor for most gaseous and particulate air pollutants. The other strong predictors were outdoor concentration, smoking, attached garage and AER (in descending order).

    2002-06-01

    Full Text Available Sick building syndrome describes a number of mostly unspesific complaints of some occupants of the building. The exact pathophysiological mechanism remains elusive. It is a multi factorial event which may include physical, chemical, biological as well as psycological factors. In many cases it is due to insufficient maintenance of the HVAC (heating, ventilation, air conditioning system in the building. Sign and symptoms can be uncomfortable and even disabling, which may include mucus membrane irritation, neurotoxic symptoms, asthma like symptoms, skin complaints, gastrointestinal symptoms and other related symptoms. There are various investigation methods to diagnose sick building syndrome, and on site assessment of the building is extremely useful. Prevention through a proactive air quality monitoring program is far more desirable than dealing with an actual sick building. Indoor air and the sick building symdrome serves as a paradigm of modern occupational and environmental medicine.

    Science.gov (United States)

    O'Donnell, Thomas W.

    2002-04-01

    David Deutsch (Oxford University) is known for ``Deutsch's algorithmm"---for going beyond the initial ideas about quantum computing (QC) of Benioff, Bennett and Feynman, to describe a quantum Turing machine, and sparking today's widespread experimental research to actually build one. Deutsch does not accept the standard Copenhagen Interpretation (CI) of quantum mechanics (QM); he supports the Many Worlds Interpretation (MWI) and credits it for his insights. In his book, The Fabric of Reality, and numerous articles and talks, he argues that the the adoption of the MWI is phnecessary for making the advances required for quantum computing. His argues that physicists must resolutely take a ``realistic" viewpoint to its logical conclusions, and, that the MWI is phthe realistic theory. In response to ubiquitous assertions by the majority of physicists that ``both systems give the same numbers," and ``all physics does (or can do) is to predict the outcome of experiments," he argues strenuously for the importance of explanations in quantum physics, and to scientific progress in general. Hence, I argue that there are two, reasonably separable, layers here: (i) opposition to positivist and instrumentalist arguments against the validity and/or value of phany explanation(s) phas such, and (ii) an argument about just what is the correct explanation: the MWI over the CI. While establishing the validity of (i) may possibly undermine CI's spirit, nevertheless (i) can be strongly validated independent from complicatons of an overlap with issues of the interpretation of QM. I develop some simple, historical contradictions regarding point (i), (without passing judgement on Deutsch's MWI or involving the CI). For example, the majority viewpoint identifies its seemingly ``non- philosophical" and non-``methaphysical" mindset as archtypically ``scientific", while seemingly quite unaware of the theoretical difficuties with positivist notions of truth, such as the fact that the foundations

    1978-08-01

    Energy controls can perform a valuable function in energy conservation or energy-management strategy in buildings. While the more-simple controls can be applied to virtually any building, the more-complex automation systems are currently available only to large buildings where their greater costs may be justified. At the present, however, there is a lack of effective, automatic energy-management control practices and schemes available for application to small buildings. This is due, in large measure, to the absence of cost-effective integrated control equipment in the small-building marketplace. Furthermore, a general philosophy or strategy, for the application of equipment for total energy conservation in small commercial buildings has not yet evolved. Both technical and marketing issues related to the implementation of automation systems in small commercial buildings under 75,000 square feet gross area are explored. The functional requirements for small-building automation systems are identified and determination of system costs and energy savings potential are made. Market analyses identify cost and payback requirements as well as attitudes of potential equipment buyers in the small-building market. Schools, apartments, and offices, which together consume more than half the energy of the small-building market, are used as analysis models. The market and technical analyses are combined to formulate the potential marketplace for a small building AEMS in terms of building size, and building type. An AEMS concept is defined which embodies the necessary functional requirements within a framework of applied strategy to energy conservation in buildings.

    This paper is a presentation of an 'instrument' for the optimization of the functionality and conservation of tertiary buildings. This technique has several different names: Building Automation Systems (BAS), Central Control and Monitoring System (CCMS) in English, and Gestion Technique du Bâtiment' (GTB) or Gestion Technique Centralisée (GTC) in French. With this technique it is possible to manage all the functions of a building, it is a modern instrument that introduces the concept of 'automation' in the operation of buildings using computerized procedures, earlier reserved for industrial processes. The system is structured with different automation levels with a distributed intelligence, each level characterized by a communication system (Fieldbus for the lowest and Ethernet for the highest level). In order to apply the BAS to CERN buildings it is necessary to evaluate the advantages, the CERN requirements and the integration with the several existing control and automation systems.

  13. LEVERAGING TREATMENT OF SALT ATTACK AND RISING DAMP IN HERITAGE BUILDINGS IN PENANG, MALAYSIA

    Directory of Open Access Journals (Sweden)

    Haris Fadzilah Abdul Rahman

    2010-06-01

    Full Text Available Of the common building defects that occur in heritage buildings in Penang, Malaysia, salt attack and rising damp are considered the most challenging, particularly for building conservation. The problem of salt attack is closely associated with rising damp. Moisture from the rising damp makes the building’s existing salts soluble, or ground water that contains salt finds its way through the building wall. This moisture then evaporates on or just below the wall’s surface, leaving salt residue behind. High salt concentrations in masonry walls cause extensive fretting and crumbling of the lower parts of walls. These formations gradually contribute to building dilapidation and reduce the building’s aesthetic value. Sodium chloride and calcium sulphate are commonly found in masonry walls, apart from other forms of salts. The sources of these salts may be natural or manmade. This paper is based on research into the problems of salt attack and rising damp in heritage masonry buildings in Penang, Malaysia. Based on a case study of five buildings in Penang, the research findings showed that these buildings faced several common building defects, including salt attack and rising damp. Treatment guidelines for salt attack and rising damp are proposed within the Malaysian context of architectural heritage and climatic conditions.

    Directory of Open Access Journals (Sweden)

    Håkan Berglund-Lake

    2008-08-01

    Full Text Available After the Second World War an intense period of modern housingconstruction started in Sweden, which suddenly changed the circumstances of everyday life for a great number of the Swedish population. The tenants were offered apartments equipped with central heating, kitchen with fridge and electric cooker, and bathroom with bathtub. These dwellings gave rise to new experiences for everyone who moved in. By ordering their things and establishing new everyday routines and habits, people appropriated this new and unfamiliar space and made it one with their ongoing life. In this process of spatial organisation and routinisation new borderlines were drawn and new meanings were given to categories such as private-public, indoor-outdoor, home-outer world, us and them. Applying a theoretical approach from phenomenology, based on life story interviews with people who experienced these modern apartments in their capacity as the first tenants, the article elucidates how people through their daily habitual actions, in interaction with things and consociates both delimited and positioned themselves in connection with a wider world. Namely, how they established a relationship between private and public realms, home and not-home, inside and outside, “us” and “them”, and, furthermore, how they transformed an unfamiliar space into a familiar place, a place they could call their own.

    Full Text Available Although social, economic, and cultural indicators are of substantial importance to the concept of sustainable building, this concept is usually related to environmental characteristics. Any building level assessment method is complex and involves contradictory aspects. Moreover, emphasizing qualitative criteria only increases confusion. R&D and standardization are thus concentrated to transparency and usability of the environmental methods. Other directions of research aim at performance-based design and methods to take regional and cultural aspects into account. In this paper, the perspectives of the sustainability assessment of a whole building are presented, based on a state of the art, feasibility study on performance analysis and the development of an extended life-cycle assessment for buildings. Using various tools, and based on the case studies of building sustainability assessment, environmental indicators were often shown to be of lesser importance than the other, soft ones. The first steps in the development of a building sustainability assessment method for Portuguese residential buildings will be presented and discussed in the end.

    This is a study of the issues and opportunities for building-integrated PV products, seen primarily from the perspective of the design community. Although some quantitative analysis is included, and limited interviews are used, the essence of the study is qualitative and subjective. It is intended as an aid to policy makers and members of the technical community in planning and setting priorities for further study and product development. It is important to remember that the success of a product in the building market is not only dependent upon its economic value; the diverse group of building owners, managers, regulators, designers, tenants and users must also find it practical, aesthetically appealing and safe. The report is divided into 11 sections. A discussion of technical and planning considerations is followed by illustrative diagrams of different wall and roof assemblies representing a range of possible PV-integration schemes. Following the diagrams, several of these assemblies are then applied to a conceptual test building which is analyzed for PV performance. Finally, a discussion of mechanical/electrical building products incorporating PVs is followed by a brief surveys of cost issues, market potential and code implications. The scope of this report is such that most of the discussion does not go beyond stating the questions. A more detailed analysis will be necessary to establish the true costs and benefits PVs may provide to buildings, taking into account PV power revenue, construction costs, and hidden costs and benefits to building utility and marketability.

    Through its Building Technologies Office (BTO), the United States Department of Energy’s Office of Energy Efficiency and Renewable Energy (DOE-EERE) is sponsoring an effort to advance interoperability for the integration of intelligent buildings equipment and automation systems, understanding the importance of integration frameworks and product ecosystems to this cause. This is important to BTO’s mission to enhance energy efficiency and save energy for economic and environmental purposes. For connected buildings ecosystems of products and services from various manufacturers to flourish, the ICT aspects of the equipment need to integrate and operate simply and reliably. Within the concepts of interoperability lie the specification, development, and certification of equipment with standards-based interfaces that connect and work. Beyond this, a healthy community of stakeholders that contribute to and use interoperability work products must be developed. On May 1, 2014, the DOE convened a technical meeting to take stock of the current state of interoperability of connected equipment and systems in buildings. Several insights from that meeting helped facilitate a draft description of the landscape of interoperability for connected buildings, which focuses mainly on small and medium commercial buildings. This document revises the February 2015 landscape document to address reviewer comments, incorporate important insights from the Buildings Interoperability Vision technical meeting, and capture thoughts from that meeting about the topics to be addressed in a buildings interoperability vision. In particular, greater attention is paid to the state of information modeling in buildings and the great potential for near-term benefits in this area from progress and community alignment.

    2005-05-01

    Green buildings, also known as sustainable buildings, resource efficient buildings, and high performance buildings, are structures that minimize the impact on the environment by using less energy and water, reducing solid waste and pollutants, and limiting the depletion of natural resources. As Idaho National Laboratory (INL) becomes the nation’s premier nuclear energy research laboratory, the physical infrastructure will be established to help accomplish the mission. This infrastructure, particularly the buildings, should incorporate green design features in order to be environmentally responsible and reflect an image of progressiveness and innovation to the public and prospective employees. With this in mind, the recommendations described in this strategy are intended to form the INL foundation for green building standards. The recommendations in this strategy are broken down into three levels: Baseline Minimum, Leadership in Energy and Environmental Design (LEED)Certification, and Innovative. Baseline Minimum features should be included in all new occupied buildings no matter what the purpose or size. These features do not require significant research, design, or capital costs and yet they can reduce Operation and Maintenance (O&M) costs and produce more environmentally friendly buildings. LEED Certification features are more aggressive than the Baseline Minimums in that they require documentation, studies, and/or additional funding. Combined with the Baseline Minimums, many of the features in this level will need to be implemented to achieve the goal of LEED certification. LEED Silver certification should be the minimum goal for all new buildings (including office buildings, laboratories, cafeterias, and visitor centers) greater than 25,000 square feet or a total cost of $10 million. Innovative features can also contribute to LEED certification, but are less mainstream than those listed in the previous two levels. These features are identified as areas where

    Full Text Available The main object of this study is the reconstruction, renovation and modernization of the housing built in the period 1975—1985. These buildings have low energy efficiency due to the poor thermal insulation properties of the walls. These apartments do not meet the necessary requirements for year round warmth and comfort.Reconstruction is more preferable, than new-build, because of the cost saving for the land acquisition. Reconstruction is generally 1.5 times cheaper than new-build with 25—40 % reduced cost on building materials and engineering infrastructure.Increasing the width of the apartment blocks from 12 to 15 m can save 9—10 % on the consumption of thermal energy for heating and reduce the m2 construction cost by 5.5—7.0 %. In—5-9 storey high-rise buildings the savings are 3—5 %.Therefore, the width of the apartment block should preferably be between 9—12 m but could be extended to 18 m. The depth of the apartments themselves will be 5.4 — 6.0 —7.2 or 9.0 m. During the reconstruction of 5-storey residential buildings (Building Type105 in a seismic zone, an increase in the width of the block and the lateral stiffness of the building is achieved by building a new reinforced concrete (RC frame on both sides of the building with a depth of between 2 and 6 m. This technique is especially effective in increasing the seismic resistance of the building. Self-supporting walls of cellular concrete blocks (density 600 kg/m3 and a thickness of 300 mm are constructed on the outside of the frame, taking care to avoid cold bridges.Model studies have shown that in the conditions of hot-arid climate the thickness of the air gap in a ventilated facade does not significantly change the cooling-energy consumption of the building, and heating consumption is significantly increased. The building's energy consumption is most influenced by the volume of the air in the air gap. By increasing the ventilation rate in the air gap, the energy

    Exhaust ventilation and corresponding outdoor air strategies are being implemented in high-performance new construction multifamily buildings to meet program or code requirements for improved indoor air quality, but a lack of clear design guidance is resulting in poor performance of these systems despite the best intentions of the programs or standards. CARB's 2014 'Evaluation of Ventilation Strategies in New Construction Multifamily Buildings' consistently demonstrated that commonly used outdoor air strategies are not performing as expected. Of the four strategies evaluated in 2014, the exhaust ventilation system that relied on outdoor air from a pressurized corridor was ruled out as a potential best practice due to its conflict with meeting requirements within most fire codes. Outdoor air that is ducted directly to the apartments was a strategy determined to have the highest likelihood of success, but with higher first costs and operating costs. Outdoor air through space conditioning systems was also determined to have good performance potential, with proper design and execution. The fourth strategy, passive systems, was identified as the least expensive option for providing outdoor air directly to apartments, with respect to both first costs and operating costs. However, little is known about how they actually perform in real-world conditions or how to implement them effectively. Based on the lack of data available on the performance of these low-cost systems and their frequent use in the high-performance building programs that require a provision for outdoor air, this research project sought to further evaluate the performance of passive vents.

    Data from a recent Swedish survey on the status of the housing stock and indoor air quality were placed in the public domain by the Swedish National Board of Housing, Building and Planning in 2011. The available parameters included the year of construction, dwelling location, type of ventilation...... system, temperature, relative humidity, air exchange rate (AER), and concentrations of nitrogen dioxide (NO2), formaldehyde and Total Volatile Organic Compounds (TVOC) from 157 single-family houses and 148 apartments. The median AER was lower in the single-family houses than in apartments (0.33h-1 vs. 0.......47h-1). The majority of houses (80%) did not comply with the building code that requires 0.5 air changes per hour. The median concentrations in single-family houses and apartments were 6.0 and 10μg/m3, respectively, for NO2, 22 and 13μg/m3 for formaldehyde, and 236 and 143μg/m3 for TVOC. All of these...

  8. Alternative methods for evaluation of airtightness of the building envelope; Alternativa metoder foer utvaerdering av byggnadsskalets lufttaethet

    Sikander, Eva; Wahlgren, Paula

    2008-07-01

    Airtightness plays an important role when constructing energy efficient, sustainable and healthy buildings. In order to obtain airtight buildings, the airtightness needs to be evaluated during the construction phase. This enables improvements of the airtightness in an easy and cost-efficient way. During the construction phase, it is difficult to quantify the airtightness. However, detecting and sealing air leakages are good measures to improve the airtightness of the building. Several methods to detect air leakages are presented. A methodology to search for air leakages in buildings during construction has been developed, together with contractors and experts, and the methodology has been used at two building sites. The quantifiable airtightness of a building is determined by measuring the airflow that enters or exits the building at a certain pressure difference over the building envelope. In some cases it is not possible to measure air tightness according to standard. Therefore, a number of alternative methods have been evaluated. These methods include: extrapolation of measured data to a range used in standard measurements, using a buildings ventilation system fans to create a pressure difference over the building envelope, measuring the airtightness of a smaller part of the building (apartment, fire compartment or component) and tracer gas measurements

  20. Alkaline intrusion in a granulite ensemble in the Eastern Ghats belt, India: Shear zone pathway and a pull-apart structure

    Indian Academy of Sciences (India)

    S Bhattacharya; Rajib Kar

    2004-03-01

    The alkaline complex of Koraput, Orissa, India, is one of several bodies in the high-grade Eastern Ghats belt, but this one is an integral part of the high-grade belt and remote from the western boundary against the Bastar craton. The Koraput complex forms a lozenge-shaped intrusion into the metapelitic granulites and is bounded by shear zones. The combined effect of movement along these shear zones, is a northeasterly elongated sygmoidal cavity with maximum width along the northwesterly trending Reidel shear. Thus the Koraput alkaline complex can be considered to have been emplaced in a pull-apart structure, developed in the granulitic country rocks. Moreover, in view of the fact that the western margin of the high-grade Eastern Ghats belt bears clear evidence of collisional features, rather than that of rifting or break-up, the rift-valley model for the alkaline magmatism in this high-grade belt appears untenable.

    The paper is focused on the building ad-hoc GSM network based on open source software and low-cost hardware. The created Base Transmission Station can be deployed and put into operation in a few minutes in a required area to ensure private communication between connected GSM mobile terminals. The convergence between BTS station and the other networks is possible through IP network. The paper tries to define connection parameters to provide sufficient quality of voice service between the GSM network and IP Multimedia Subsystem. The paper brings practical results of voice call quality measurement between users inside BTS station mobile network and users inside IP Multimedia Subsystem network. The calls are simulated by low-cost embedded solution for speech quality measurement in GSM network. This tool is under development of our laboratory and allows automatic speech quality measurement of any GSM or UMTS mobile network. The Perceptual Evaluation of Speech Quality method is used to get final comparable results. The communication between BTS station and connected networks has to be secured against the interception from the third party. The influence of the securing method for quality of service is presented in detail. Paper, apart from the quality of service measurement section, describes technical requirements for successful interconnection between BTS and IMS networks. The authentication, authorization and accounting methods in roaming between BTS and IMS system are presented too.

  5. Comparison of cardiovascular disease patterns in two data sets of patients admitted at a tertiary care public hospital in Karachi five years apart

    International Nuclear Information System (INIS)

    To compare the disease patterns in two data sets of patients, five years apart, at the National Institute of Cardiovascular Diseases (NICVD), a tertiary care cardiac hospital in Karachi. The underlying objective was to determine any changes in cardiovascular disease patterns at an acute cardiac unit over a period of five years. A retrospective descriptive study was conducted on patients admitted in West Ward, National Institute of Cardiovascular Diseases (NICVD), Karachi in September, 2000 and September, 2005. Patient's record files were reviewed and the relevant information was recorded on a proforma designed for the purpose. In September, 2000, a total of 414 patients were admitted. Of these 71.25% were males. Majority of patients (72.92%) were in the fifth decade of life or beyond. Acute coronary syndrome (ACS) was the commonest presentation, present in 39.8% of the patients. 27.3% had myocardial infarction (MI) while 10.34% were diagnosed with heart muscle diseases. The overall mortality was 3.4%. In September, 2005, a total of 446 patients were admitted. Of these, 63% were males. 71.29% were in the fifth, sixth, and seventh decades of life. 43.04% patients were admitted with acute coronary syndromes (ACS), 26% with myocardial infarction (MI) and 13.45% with heart muscle diseases. The overall mortality was 1.34%. The almost similar results in two data sets of patients five years apart suggests that the cardiovascular disease burden and pattern has not changed significantly at this center. There is a preponderance of cardiovascular illnesses in males and older age groups. ACS and MI account for majority of admissions. (author)

    Full Text Available Abstract Background Land Use Regression models (LUR are useful to estimate the spatial variability of air pollution in urban areas. Few studies have evaluated the stability of spatial contrasts in outdoor nitrogen dioxide (NO2 concentration over several years. We aimed to compare measured and estimated NO2 levels 12 years apart, the stability of the exposure estimates for members of a large cohort study, and the association of the exposure estimates with natural mortality within the cohort. Methods We measured NO2 at 67 locations in Rome in 1995/96 and 78 sites in 2007, over three one-week-long periods. To develop LUR models, several land-use and traffic variables were used. NO2 concentration at each residential address was estimated for a cohort of 684,000 adults. We used Cox regression to analyze the association between the two estimated exposures and mortality. Results The mean NO2 measured concentrations were 45.4 μg/m3 (SD 6.9 in 1995/96 and 44.6 μg/m3 (SD 11.0 in 2007, respectively. The correlation of the two measurements was 0.79. The LUR models resulted in adjusted R2 of 0.737 and 0.704, respectively. The correlation of the predicted exposure values for cohort members was 0.96. The association of each 10 μg/m3 increase in NO2 with mortality was 6 % for 1995/96 and 4 % for 2007 LUR models. The increased risk per an inter-quartile range change was identical (4 %, 95 % CI:3–6 % for both estimates of NO2. Conclusions Measured and predicted NO2 values from LUR models, from samples collected 12 years apart, had good agreement, and the exposure estimates were similarly associated with mortality in a large cohort study.

    This paper analyzes the thermal and energy behaviour of apartments in three-story block buildings located along a NE-SW axis (azimuth = 120 ) in a temperate-cold climate (latitude: 36 57'; longitude: 64 27') in the city of Santa Rosa, La Pampa, central Argentina. Four apartments had been monitored during May and June 2009. Three of them are located in Block 126. Two of these apartments face South: 15 and 23 on the SE end, ground and first floor, respectively; 18 faces N on the second floor. Finally apartment, 12 is located in Block 374, on the first floor, faces N and shows a carpentry-closed balcony. The purpose of this work is - to study the evolution of the indoor temperature in each apartment; to analyze energy consumption and comfort conditions; to study energy potential and energy intervention in order to reduce energy consumption; to analyze bioclimatic alternatives feasibility and the possibility to extrapolate results to all blocks. On the basis of the analysis of natural gas historical consumption records, results showed that regarding heating energy consumption during the period May-June, Apartment 12, facing N, with its only bedroom facing NW and its carpentry-closed, transparent glass balcony, presented a mean temperature of 21.2 C, using a halogen heater for 6 h/day between 9 pm and 2 am (0.16 kWh/day/m{sup 2}). Apartment 15, on the SE end, first floor of the block consumed 22.5 kWh/day (0.43 kWh/day/m{sup 2}) (mean temperature = 22.2 C). Apartment 23, located on the second and top floor (on top of Apartment 15) with higher energy loss, consumed 28 kWh/day (0.54 kWh/day/m{sup 2}) (mean temperature 23.7 C). Apartment 18, also on the second floor and facing N, located in the centre and with its only bedroom facing SE, consumed 18.8 kWh/day (0.48 kWh/day/m{sup 2}) (mean temperature = 22.3 C). Apartment 23, with higher thermal loss through its envelope, but with heat transfer from the apartment located below, is the one that showed the highest

  13. Building air exhaustion device

    International Nuclear Information System (INIS)

    An opening is formed on the side wall of a building such as of a nuclear power plant, and a blow out panel is held (supported) by a clip for closing the opening. A large-diameter pipeline is connected at one end to the opening so as to cover the blow out panel, and immersed at the other end in a pool water. When a pipeline such as of main steam pipelines is ruptured in the building, high temperature and high pressure coolants are flown out from the ruptured port, and the pressure in the building is elevated. The blow out panel falls off from the side of the building by the elevation of the pressure in the building. Steams or compressed air discharged from the opening is introduced to the pool through the large diameter pipeline, then the steams are condensed by the pool water and radioactive materials contained in the condensed steams are kept in the pool water. Radioactive materials contained in the released compression air are also removed into the pool water. (I.N.)

    2009-01-01

    One of the most important goals of information management (IM) is supporting the knowledge workers in performing their works. In this paper we examine issues of relevance, linkage and provenance of information, as accessed and used by the knowledge workers. These are usually not adequately addressed in most of the IT based solutions for IM. Here we propose a non-conventional approach for building information systems for supporting the knowledge workers which addresses these issues. The approach leads to the ideas of building Information Warehouses (IW) and Knowledge work Support Systems (KwSS). Such systems can open up potential for building innovative applications of significant impact, including those capable of helping organizations in implementing processes for double-loop learning.

    1994-01-01

    We describe a project to capitalize on newly available levels of computational resources in order to understand human cognition. We will build an integrated physical system including vision, sound input and output, and dextrous manipulation, all controlled by a continuously operating large scale parallel MIMD computer. The resulting system will learn to 'think' by building on its bodily experiences to accomplish progressively more abstract tasks. Past experience suggests that in attempting to build such an integrated system we will have to fundamentally change the way artificial intelligence, cognitive science, linguistics, and philosophy think about the organization of intelligence. We expect to be able to better reconcile the theories that will be developed with current work in neuroscience.

    It is logical to believe that the building professionals (architect, structural engineers, building services engineers, etc.) are the relevant persons that may influence the decision-making process on a real estate development process. Accordingly, the attitudes and perception of building professionals should have a significant influence on sustainable development. This article describes a survey concerning the perceptions of different building professionals, which include architects, construction engineers and building services engineers, on the environment, resource sustainability, and green consumerism in two major cities in China: Hong Kong and Shenyang. It is recognized that energy is central to sustainable development and in 2006/2007, the United Nation Commission on Sustainable Development will focus on energy issue. The discussion in this article will concentrate on the building professionals' perception on energy related issues. Nevertheless, the findings in respect of their awareness of the environment, resources sustainability and other related issues are also summarized. At global level, apart from the need to preserve historical buildings, the professionals in Shenyang feel that 'exhaustion of natural resources' is of major concern and energy preservation is significant. However, the Hong Kong professionals do not consider energy resource sustainability is of urgency. (author)

  12. Ways of modernization of large-panel residential buildings in Yerevan

    Directory of Open Access Journals (Sweden)

    Hakobyan Tigran Davidovich

    Full Text Available The present article discusses some problems of renovation and modernization of large-panel residential buildings built in the postwar period in Yerevan. The analysis of the current situation showed that today these buildings have many problems related to their functional and aesthetic aspects of quality and become obsolete. The floor plans don’t satisfy modern functional requirements of inhabitants: similar and repeatable types of buildings became the reason of large arrays of monotonously built up districts with low indicators of quality. Furthermore, there are many low quality extensions and add-ins to the buildings made by inhabitants without control, which destroy the architectural appearance of habitat. Yard places of large-panel residential buildings are occupied by car parks and road travel, buildings are cut off from courtyard areas, which as a consequence don’t meet tsocial and functional requirements of the people. The consideration of the international experience of large-panel old housing renovation in European countries has shown that the main activities include improving the energy efficiency of residential buildings with removing heat loss and using solar panels, contrast changes in architectural appearance with large terraces, loggias, using wide range of colors, add-in attics and enlarging the height and the use of space-planning decisions to increase the living space. Analyzing the current situation of the housing and the international experience of modernization the concept of complex modernization of large-panel buildings was offered, which suggested bringing it to life on three main levels of habitat: apartments, building shapes, residential environment and areas. The main goals of the concept are increasing the comfort of planning decisions as well as the total size of the apartment, improving architectural appearance of the building and introducing areas for public services to housing, increasing energy efficiency and

  13. Deactivation of Building 7602

    International Nuclear Information System (INIS)

    The Department of Energy (DOE) has sponsored research and development programs in Building 7602 at Oak Ridge National Laboratory (ORNL) since 1984. This work focused on development of advanced technology for processing nuclear fuels. Building 7602 was used for engineering-scale tests using depleted and natural uranium to simulate the nuclear fuel. In April 1994 the DOE Office of Nuclear Energy (NE) sent supplemental FY 1994 guidance to ORNL stating that in FY 1995 and beyond, Building 7602 is considered surplus to NE programs and missions and shall be shut down (deactivated) and maintained in a radiologically and industrially safe condition with minimal surveillance and maintenance (S ampersand M). DOE-NE subsequently provided FY 1995 funding to support the deactivation activities. Deactivation of Building 7602 was initiated on October 1, 1994. The principal activity during the first quarter of FY 1995 was removal of process materials (chemicals and uranium) from the systems. The process systems were operated to achieve chemical solution concentrations needed for reuse or disposal of the solutions prior to removal of the materials from the systems. During this phase of deactivation the process materials processed and removed were: (1) Uranyl nitrate solution 30,178 L containing 4490 kg of uranium; (2) Nitric acid (neutralized) 9850 L containing less than 0.013 kg of uranium; (3) Organic solution 3346 L containing 265 kg of uranium; (4) Uranium oxide powder 95 kg; and (5) Miscellaneous chemicals. At the end of December 1994, the process systems and control systems were shut down and deactivated. Disposition of the process materials removed from the process systems in Building 7602 proved to be the most difficult part of the deactivation. An operational stand down and funding reductions at Y-12 prevented planned conversion of the uranyl nitrate solution to depleted uranium oxide powder. This led to disposal of the uranyl nitrate solution as waste

    Recent accomplishments in buildings energy research by the diverse groups in the Energy Efficient Buildings Program at Lawrence Berkeley Laboratory (LBL) are summarized. We review technological progress in the areas of ventilation and indoor air quality, buildings energy performance, computer modeling, windows, and artificial lighting. The need for actual consumption data to track accurately the improving energy efficiency of buildings is being addressed by the Buildings Energy Data (BED) Group at LBL. We summarize results to date from our Building Energy Use Compilation and Analysis (BECA) studies, which include time trends in the energy consumption of new commercial and new residential buildings, the measured savings being attained by both commercial and residential retrofits, and the cost-effectiveness of buildings energy conservation measures. We also examine recent comparisons of predicted vs. actual energy usage/savings, and present the case for building energy use labels.

  16. Marginal Productivity Gained Through Prefabrication: Case Studies of Building Projects in Auckland

    Directory of Open Access Journals (Sweden)

    Wajiha Shahzad

    2015-02-01

    Full Text Available Several studies have documented benefits of prefabrication system (prefab compared to the traditional building system (TBS. However, the documented benefits have been anecdotal or fragmented with reports of isolated case study projects. Few studies have looked at the objectively quantified benefits from statistical significance point of view and across building types in New Zealand. This study contributes to filling this knowledge gap by analyzing cost and time-savings, and productivity improvement achievable by the use of prefab in place of the TBS. Records of completion times and final contract values of 66 building projects implemented using prefab in Auckland were collected. The building types included commercial, houses, apartments, educational, and community buildings. The project details included final contract sums, completion dates, gross floor areas, and number of floors. Based on these details, the equivalent completion times and the final cost estimates for similar buildings implemented using the TBS were obtained from the Rawlinsons construction data handbook and feedback from some designers and contractors. Marginal productivity outcome for each building project was computed as the product of the cost and time-savings achieved using the prefab. Results showed that the use of prefab in place of TBS resulted in 34% and 19% average reductions in the completion times and costs, respectively. This also translated to overall 7% average improvement in the productivity outcomes in the building projects. Univariate ANOVA-based hypothesis test results showed that ‘building type’ had no significant effects on the cost and productivity improvement outcomes, but had significant effect on the time savings analyzed in the case study projects. The greatest productivity gain of 11% was achieved in house projects. These evidence-based results could guide optimized use of prefab for specific building application.

  1. Radon in residential buildings

    International Nuclear Information System (INIS)

    For the investigation, a passive integrating radon dose meter developed at the KfK Karlsruhe was used. This institute also carried out the evaluation of all dose meters. The inquiry data were collected and statistically evaluated centrally by the Radiation Hygiene Institute of the German Health Authorities. Results obtained from almost 6.000 appartments show a distinct regional distribution of the measured values closely related to the geological conditions of the respected area. Surprisingly, there was little dependency on the building materials, with the exception of natural stone houses. The analysis showed that the structural characteristics of a building likely to influence the penetration of radon from the soil have a great effect on the Rn level. Generally, the frequency distribution of the measured values follows a logarithmic Gaussian distribution. Based on a median of 40 Bg/m3, the annual effective dose equivalent is about 1 mSv.

    2015-01-01

    Focusing on both homemade and commercial products, this book provides the reader with simple and straightforward information about the modelling and building of binoscopes. Binoscopes can be thought of as binoculars enlarged to the size of telescopes: essentially, a combination of the two. Constructing a binoscope is easier than most people think, but it still demands attention to detail and proper background knowledge. The author goes on to provide additional information about how to understand the products currently on the market, should the reader choose to purchase a binoscope instead of building one. Lastly, the book also compares binoscopes with telescopes in great detail, outlining the differences the reader can expect to see in the night sky from using both. The celestial views obtained with a binoscope, compared to a single telescope of the same aperture, are a very different experience and well worth the effort.

    Cellular memory – conversion of a transient signal into a sustained response – is a common feature of biological systems. Synthetic biologists aim to understand and reengineer such systems in a reliable and predictable manner. Synthetic memory circuits have been designed and built in vitro and in vivo based on diverse mechanisms such as oligonucleotide hybridization, recombination, transcription, phosphorylation, and RNA editing. Thus far, building these circuits has helped us explore the bas...

    Some instances of creative thinking require an agent to build and test hypothetical theories. Such a reasoner needs to explore the space of not only those situations that have occurred in the past, but also those that are rationally conceivable. In this paper we present a formalism for exploring the space of conceivable situation-models for those domains in which the knowledge is primarily probabilistic in nature. The formalism seeks to construct consistent, minimal, and desirable situation-d...

  15. Flavored model building

    International Nuclear Information System (INIS)

    In this thesis we discuss possibilities to solve the family replication problem and to understand the observed strong hierarchy among the fermion masses and the diverse mixing pattern of quarks and leptons. We show that non-abelian discrete symmetries which act non-trivially in generation space can serve as profound explanation. We present three low energy models with the permutation symmetry S4, the dihedral group D5 and the double-valued group T' as flavor symmetry. The T' model turns out to be very predictive, since it explains tri-bimaximal mixing in the lepton sector and, moreover, leads to two non-trivial relations in the quark sector, √((md)/(ms))= vertical stroke Vus vertical stroke and √((md)/(ms))= vertical stroke (Vtd)/(Vts) vertical stroke. The main message of the T' model is the observation that the diverse pattern in the quark and lepton mixings can be well-understood, if the flavor symmetry is not broken in an arbitrary way, but only to residual (non-trivial) subgroups. Apart from leading to deeper insights into the origin of the fermion mixings this idea enables us to perform systematic studies of large classes of discrete groups. This we show in our study of dihedral symmetries Dn and D'n. As a result we find only five distinct (Dirac) mass matrix structures arising from a dihedral group, if we additionally require partial unification of either left-handed or left-handed conjugate fermions and the determinant of the mass matrix to be non-vanishing. Furthermore, we reveal the ability of dihedral groups to predict the Cabibbo angle θC, i.e. vertical stroke Vus(cd) vertical stroke cos((3π)/(7)), as well as maximal atmospheric mixing, θ23=(π)/(4), and vanishing θ13 in the lepton sector.

  16. Building for energy conservation

    Energy Technology Data Exchange (ETDEWEB)

    Burberry, P.

    1978-01-01

    Ways in which buildings may be designed to increase thermal efficiency are discussed, giving first of all examples of thermal design in relation to climate. How the building itself may be designed to take advantage of solar energy and the ways in which heat loss takes place are described; the effect of design variables such as siting, volume, and insulation is shown. The book also reviews the development of thermal regulations for health and comfort and, more recently, energy conservation. It discusses the possitilities and difficulties of legislation for energy saving. The UK regulations are given in detail together with descriptions of the FHA and ASHRAE recommendations for the USA and the lastest Scandinavian norms. The author argues that no significant cost need be involved in many of the aspects of thermal design, e.g., shape and fenestration; and that these factors should automatically be taken into account by designers. Even existing buildings can be adapted in various respects to save energy consumption. The book concludes with an explanation of calculation methods for U-values, heat loss, plant sizing, seasonal heat requirements, and other procedures, amply illustrated with tables and graphs.

  6. Compliance with building energy regulations for new-build dwellings

    International Nuclear Information System (INIS)

    Despite increasingly stringent building energy regulations worldwide, non-compliance exists in practice. This paper examines the profile of compliance with building energy regulations for new-build dwellings. In total 404 new-build dwellings completed in the UK from 2006 to 2009 were investigated. Only a third of these dwellings were evidenced as being compliant with Building Regulations Part L (England and Wales). Such low compliance casts a serious concern over the achievability of the UK Government's target for all new-build homes to be ‘zero carbon’ from 2016. Clearly evidenced was a lack of knowledge of Part L and its compliance requirements among the supply and building control sides of new-build dwellings. The results also indicate that the compliance profile was influenced by factors including Standard Assessment Procedure (UK Government's methodology for energy efficiency) calculation submissions, learning and experience of builders and building controls with Part L, use of Part L1A checklist, the introduction of energy performance certificate (EPC), build method, dwelling type, and project size. Better compliance was associated with flats over houses and timber frame over masonry. The use of EPC and Part L1A checklist should be encouraged. Key to addressing the lack of compliance with building energy regulations is training. -- Highlights: ► There exists a lack of compliance, worldwide, with building energy regulations. ► The implementation of England and Wales building energy regulations is problematic. ► Training, learning and experience of builders and building control are critical. ► Energy performance certificate and Part L 2006 checklist helped achieve compliance. ► Flats achieved better compliance over houses; and timber frame over masonry.

    Full Text Available Building athletic performance is a process that involves, apart from athletes and coaches, a vast number of specialists from many related fields – the behind-the-scenes people. We do not propose to establish the ratio by which these unseen participants contribute to the overall performance of the athlete, nor to build a hierarchy of these unseen contributors, or to maximize or minimize their part. What we wish to accomplish is to shed some light on one aspect which has resulted from our Sports Medicine practice. Over the last 9 years, we have had a constant preoccupation for identifying the traits of the human personality which could help and / or lead towards performance (in general and particularly towards athletic performance. Coaching is a branch born out of psychology, which uses specific question-building techniques in order to: -\taccompany the client / patient / athlete in the process of establishing objectives -\tidentify the paths and means for achieving the objectives -\tidentify the elements that can cause blockage on the road to athletic / intellectual performance -\tfind external and internal resources to help them advance in the desired direction -\thelp establish the steps they can take in order to achieve their goals In this article we will present 5 steps / important elements that can help build self-confidence. The results come from applying methodically the techniques borrowed from coaching, and following them over the span of 9 years. Attaining the desired level of self-confidence depends on the specificity of the chosen objective, on obtaining a clear explanation of the chosen objective from the part of the athletic coach, on identifying the possible routes for achieving that objective, on the athlete's degree of responsibility and knowledge of oneself.

  9. Building a leadership brand.

    Ulrich, Dave; Smallwood, Norm

    2007-01-01

    How do some firms produce a pipeline of consistently excellent managers? Instead of concentrating merely on strengthening the skills of individuals, these companies focus on building a broad organizational leadership capability. It's what Ulrich and Smallwood--cofounders of the RBL Group, a leadership development consultancy--call a leadership brand. Organizations with leadership brands take an "outside-in" approach to executive development. They begin with a clear statement of what they want to be known for by customers and then link it with a required set of management skills. The Lexus division of Toyota, for instance, translates its tagline--"The pursuit of perfection"--into an expectation that its leaders excel at managing quality processes. The slogan of Bon Secours Health System is "Good help to those in need." It demands that its managers balance business skills with compassion and caring. The outside-in approach helps firms build a reputation for high-quality leaders whom customers trust to deliver on the company's promises. In examining 150 companies with strong leadership capabilities, the authors found that the organizations follow five strategies. First, make sure managers master the basics of leadership--for example, setting strategy and grooming talent. Second, ensure that leaders internalize customers' high expectations. Third, incorporate customer feedback into evaluations of executives. Fourth, invest in programs that help managers hone the right skills, by tapping customers to participate in such programs. Finally, track the success of efforts to build leadership bench strength over the long-term. The result is outstanding management that persists even when individual executives leave. In fact, companies with the strongest leadership brands often become "leader feeders"--firms that regularly graduate leaders who go on to head other companies. PMID:17642128

    Full Text Available Global sustainability goals have led to the development of the green building movement. The Green Building Program, stemming from the movement, has had unprecedented success as it provides a quantifiable metric to people’s efforts towards sustainable development. Sustainable development and green buildings are often used interchangeably. Although, sustainable development and green buildings are related, they are not the same. This paper provides an overview of how green building relates to sustainable development practices. Sustainability also governs decisions concerning building materials. A comprehensive explanation of what constitutes a green building material is discussed and how renewable material like wood fare in the deciding criteria. There are many green building rating systems in place. United States Green Building Council administered Leadership in Energy and Environment Design (LEED is the global market leader in the rating systems. LEED is a commendable and grand effort in moving towards sustainable development by converting the built environment green. However, it does have certain pitfalls and challenges. Some of these challenges are with respect to policies on material selection and performance monitoring. The materials used in a project are considered at a common starting point and no consideration is given to the life cycle performance of the material. Statements concerning sustainability require validation, and Life Cycle Analysis (LCA is a tool that can provide such validity. This paper presents how beneficial it can be, when included, in the bigger scheme of green building rating systems and introduces an integrated design concept for green buildings.

    Kung, YiHsiu Michelle

    With Asia's surging economies and urbanization, the region is adding to its built environment at an unprecedented rate, especially those population centers in China and India. With numerous existing buildings, plus a new building boom, construction in these major Asian cities has caused momentous sustainability challenges. This dissertation focuses on China's leading city, Shanghai, to explore and assess its existing commercial building energy policies and practices. Research estimates that Shanghai's commercial buildings might become a key challenge with regard to energy use and CO2 emissions as compared to other major Asian cities. Relevant building energy policy instruments at national and local levels for commercial buildings are reviewed. In addition, two benchmarks are established to further assess building energy policies in Shanghai. The first benchmark is based on the synthesis of relevant criteria and policy instruments as recommended by professional organizations, while the second practical benchmark is drawn from an analysis of three global cities: New York, London and Tokyo. Moreover, two large-scale commercial building sites - Shanghai IKEA and Plaza 66 - are selected for investigation and assessment of their efforts on building energy saving measures. Detailed building energy savings, CO2 reductions, and management cost reductions based on data availability and calculations are presented with the co-benefits approach. The research additionally analyzes different interventions and factors that facilitate or constrain the implementation process of building energy saving measures in each case. Furthermore, a multi-scale analytical framework is employed to investigate relevant stakeholders that shape Shanghai's commercial building energy governance. Research findings and policy recommendations are offered at the close of this dissertation. Findings and policy recommendations are intended to facilitate commercial building energy governance in Shanghai and

    In multifamily buildings, particularly in the Northeast, exhaust ventilation strategies are the norm as a means of meeting both local exhaust and whole-unit mechanical ventilation rates. The issue of where the "fresh" air is coming from is gaining significance as air-tightness standards for enclosures become more stringent. CARB researchers have found that most new high performance, multifamily housing in the Northeast use one of four strategies for ventilation: continuous exhaust only with no designated supply or make-up air source, continuous exhaust with ducted make-up air to apartments, continuous exhaust with supply through a make-up air device integral to the unit HVAC, and continuous exhaust with supply through a passive inlet device, such as a trickle vent. Insufficient information is available to designers on how these various systems are best applied. Product performance data are based on laboratory tests, but there is no guarantee that those conditions will exist consistently in the finished building. In this research project, CARB evaluated the four ventilation strategies in the field to validate system performance.

The differenciation is caused by interactions between the labor market, individual choices and the institutional context (further education, the developping Welfare State, the reform of the system of retirement. Coupled with a study of the advances in public Schooling, negociations between fecondity and professional activity and preparation for retirement, our interpretation leads to a reappraisal of French society, seen in both its rigidities and its

This strategy and the inter-building level energy management strategies developed in my preceding research possess large-scale cost-effectiveness and may engender long-lasting influence compared with existing energy saving approaches. Building from the holistic framework of coupled human-environment systems, the findings of this research will advance knowledge of energy efficiency in the built environment and lead to the development of novel strategies to conserve energy in residential buildings.

    Full Text Available This research is to recognise the function of Building Information Modelling (BIM in design optimization for irregular shaped buildings. The study focuses on a conceptual irregular shaped “twisted” building design similar to some existing sculpture-like architectures. Form and function are the two most important aspects of new buildings, which are becoming more sophisticated as parts of equally sophisticated “systems” that we are living in. Nowadays, it is common to have irregular shaped or sculpture-like buildings which are very different when compared to regular buildings. Construction industry stakeholders are facing stiff challenges in many aspects such as buildability, cost effectiveness, delivery time and facility management when dealing with irregular shaped building projects. Building Information Modelling (BIM is being utilized to enable architects, engineers and constructors to gain improved visualization for irregular shaped buildings; this has a purpose of identifying critical issues before initiating physical construction work. In this study, three variations of design options differing in rotating angle: 30 degrees, 60 degrees and 90 degrees are created to conduct quantifiable comparisons. Discussions are focused on three major aspects including structural planning, usable building space, and structural constructability. This research concludes that Building Information Modelling is instrumental in facilitating design optimization for irregular shaped building. In the process of comparing different design variations, instead of just giving “yes or no” type of response, stakeholders can now easily visualize, evaluate and decide to achieve the right balance based on their own criteria. Therefore, construction project stakeholders are empowered with superior evaluation and decision making capability.

    The energy-efficiency gap literature suggests that building buyers are often short-sighted in their failure to apply life-cycle costing principles to energy efficient building technologies, with the result that under investment in these advanced technology occurs. This study examines the reasons this behavior may occur, by analyzing the pressures that market forces place on purchasers of buildings. Our basic conclusion is that the fundamental manner in which the buildings sector does business creates pressures to reduce initial capital outlays and to hedge against a variety of risks, including the ability of building owners to capture benefits from energy efficiency. Starting from the position that building buyers' willingness to pay drives choices over building attributes, we examine basic market principles, the structure of the buildings market, including the role of lenders, and policies that promote penetration of energy efficient technologies. We conclude that greater attention to buyers, and to the incentives and constraints they face, would promote a better understanding of building investment choices and contribute to better policies to promote the penetration of these technologies into markets.

    Full Text Available Before turning to specific programs for upgrading buildings, it’s important to understand the market dynamics of greening existing buildings. From a macroeconomic perspective, energy efficiency upgrades represent the most cost-effective way to meet growing energy demands. From a microeconomic perspective, recent studies have shown that energy-efficient and certified green buildings merit higher market values, greater rents, and higher occupancies. From a corporate sustainability viewpoint, greening existing buildings is a direct way to reduce a company’s carbon footprint. As a result, corporate real estate managers in the United States have begun to decide in favour of greening both owned and leased buildings, seeing many economic benefits from this switch. Green buildings offer many marketing benefits for building owners and tenants, including opportunities for creating new green “brands” and also “future-proofing” their real estate against both future energy price increases and also value erosion as the trend toward green buildings continues to grow. Marketing benefits will vary by geographic location, building and tenant type, and other factors, but they are present in all privately owned real estate.

    Overheating is a paramount problem in residential buildings in hot and humid climates in China during summer. This study aims to deal with the overheating problem and the problem of poor air quality in dwellings. The main objective is to improve indoor thermal conditions by passive cooling approaches, climatisation techniques in buildings without auxiliary cooling from air conditioning equipment. This thesis focuses on the study of cross-ventilation in apartments, which is one of the most effective ways of natural cooling in a hot humid climate, but is also one of the least understood parts in controlling indoor climate. The Computational Fluid Dynamics (CFD) technique is used, which is a new approach, since cross-ventilation studies have been conventionally made by wind tunnel tests. The validations of the CFD technique are examined by a comparison between wind tunnel tests and computer simulations. The factors influencing indoor air movement are investigated for a single room. Cross-ventilation in two apartments is studied, and the air change efficiency in a Chinese kitchen is calculated with CFD techniques. The thermal performance of ventilated roofs, a simple and widely used type of roof in the region, is specially addressed by means of a full-scale measurement, wind tunnel tests and computer simulations. An integrated study of passive cooling approaches and factors affecting indoor thermal comfort is carried out through a case study in a southern Chinese city, Guangzhou. This thesis demonstrates that passive cooling measure have a high potential in significantly improving indoor thermal conditions during summer. This study also gives discussions and conclusions on the evaluation of indoor thermal environment; effects influencing cross-ventilation in apartments; design guidelines for ventilated roofs and an integrated study of passive cooling. 111 refs, 83 figs, 65 tabs

    International Nuclear Information System (INIS)

    The use in home buildings in Hungary of some substitute materials, e.g., coal-ash, fly-ash, etc., caused greater background radiation than the traditional building materials because of their higher content of natural radioactivity. The radon-222 concentration was measured in 1182 flats (apartments) along with the concentrations of its short-lived daughter elements and radon-220 in room air and the radiation dose to the epithelium of the bronchial tubes of the lung was estimated. The average annual radon-222 concentration in open air was estimated as being 0.2 pCi/l. To confirm this estimate the radon-222 concentration in the atmosphere near the surface of the earth and its annual fluctuation was measured. (U.S.)

    The U.S. Department of Energy’s (DOE) residential research and demonstration program, Building America, has triumphed through 20 years of innovation. Partnering with researchers, builders, remodelers, and manufacturers to develop innovative processes like advanced framing and ventilation standards, Building America has proven an energy efficient design can be more cost effective, healthy, and durable than a standard house. As Building America partners continue to achieve their stretch goals, they have found that the barrier to true market transformation for high performance homes is the limited knowledge-base of the professionals working in the building industry. With dozens of professionals taking part in the design and execution of building and selling homes, each person should have basic building science knowledge relevant to their role, and an understanding of how various home components interface with each other. Instead, our industry typically experiences a fragmented approach to home building and design. After obtaining important input from stakeholders at the Building Science Education Kick-Off Meeting, DOE created a building science education strategy addressing education issues preventing the widespread adoption of high performance homes. This strategy targets the next generation and provides valuable guidance for the current workforce. The initiative includes: • Race to Zero Student Design Competition: Engages universities and provides students who will be the next generation of architects, engineers, construction managers and entrepreneurs with the necessary skills and experience they need to begin careers in clean energy and generate creative solutions to real world problems. • Building Science to Sales Translator: Simplifies building science into compelling sales language and tools to sell high performance homes to their customers. • Building Science Education Guidance: Brings together industry and academia to solve problems related to

  8. Energy Saving Alignment Strategy: Achieving energy efficiency in urban buildings by matching occupant temperature preferences with a building’s indoor thermal environment

    International Nuclear Information System (INIS)

    Highlights: • A novel strategy for energy savings in multi-family buildings is presented. • A household’s thermal preferences are matched with a unit’s thermal environment. • Potential energy savings are examined using public housing as a test case. • 2.1–42.0% primary energy savings are shown, depending on climate location. - Abstract: Existing strategies for residential energy savings through physical renovation or motivating occupant energy conservation behavior can be costly and/or have transitory effects. Focusing on multi-family dwellings, an important subset of the urban residential sector, we propose an Energy Saving Alignment Strategy (ESAS) that has advantageous cost-effectiveness and a long-lasting influence. By aligning the distribution of residents’ thermostat preferences with the indoor temperature, ESAS aims to maximize thermal comfort and, accordingly, energy savings in multi-family buildings where indoor temperatures vary between apartments as a function of apartment orientation and floor level. Using a case study of a 1084-apartment public housing complex in New York, we classify both occupants’ thermostat preferences and apartments’ operative temperatures into five groups, and optimize energy efficiency by assigning each group of occupants to the group of apartments that best aligns with their thermostat preference. We test ESAS in eight cities representing all four U.S. census regions and six climate zones. Simulation results reveal 2.1–42.0% in energy savings compared to random apartment assignments depending on geographic location, with the highest energy reductions occurring in cities with mild climates, where the range of occupant thermostat preferences coincides with the natural indoor temperature range. We conclude by providing suggested guidelines on how ESAS might work in practice, and recommendations for extending ESAS research

  9. Building America Case Study: Multifamily Zero Energy Ready Home Analysis, Elmsford, New York

    Energy Technology Data Exchange (ETDEWEB)

    2016-04-01

    Two multifamily buildings planned in Climate Zone 4 were analyzed to determine the cost, energy and performance implications of redesigning them to comply with Zero Energy Ready Home, a recognition program of the U.S. Department of Energy. Energy modeling was conducted on one representative apartment in each building using BEopt. Construction costs were obtained from the developer and subcontractors to determine savings and cost increases over ENERGY STAR. It was found that seven items would be necessary to change to comply with ZERH criteria when starting from the original design which was compliant with ENERGY STAR version 3.0. Design changes were made to the exterior walls, domestic water heating system, duct protection, duct design, garage ventilation, and pest control to comply with ZERH requirements. Energy impacts of upgrading from the original design to ZERH resulted in 2 to 8 percent reduction in modeled source energy consumption, or 1.7 to 10.4 MMBtu per year, although the original design was already about 8 percent better than a design configured to minimum ENERGY STAR criteria. According to the BEopt analysis, annualized energy related costs of the ZERH design were slightly higher for the apartment and slightly lower for the townhome when compared to the original design.

    This project aimed to develop a standard methodology for building energy data definition, collection, presentation, and analysis; apply the developed methods to a standardized energy monitoring platform, including hardware and software, to collect and analyze building energy use data; and compile offline statistical data and online real-time data in both countries for fully understanding the current status of building energy use. This helps decode the driving forces behind the discrepancy of building energy use between the two countries; identify gaps and deficiencies of current building energy monitoring, data collection, and analysis; and create knowledge and tools to collect and analyze good building energy data to provide valuable and actionable information for key stakeholders.

  11. Radiation exposure from building materials

    International Nuclear Information System (INIS)

    A survey procedure was developed to find buildings in which the radiation exposure from gamma rays is relatively high. For modern structures NaI(Tl) survey meters are used to identify building materials with higher radionuclide content. Samples of these materials are analyzed by gamma-ray spectroscopy for 226Ra daughters, 232Th daughters, and 40K. The exposure rate in a building is computed from these concentrations on the basis of the geometrical configuration of building materials, acting both as radiation sources and as a shield against terrestrial radiation, and also on the basis of the outside radiation exposure rate at the building site. The procedure may also be applied to surveys of building material constituents and to materials in place in older structures. A calculational model was developed to predict radiation exposure rates within the houses

    This final report for the Swiss Federal Office of Energy (SFOE) discusses the results of a preliminary study on energy and greenhouse-gas optimised building renovation. The proposals are based on the building standards proposed under the '2000-Watt Society' and 'One-Tonne CO{sub 2} Society' proposals. Comparisons are made with Swiss official building standards as well as Swiss and international standards for zero-energy and passive housing. These standards and requirements are discussed in detail and examples of buildings built to meet them are described. Building standards based on sustainability standards are also discussed and compared. The methodology to be used with respect to single-family homes and apartment blocks is discussed. Finally, knowledge gaps are identified and appropriate literature is listed.

  16. Efficiency Analysis of Independent and Centralized Heating Systems for Residential Buildings in Northern Italy

    2011-11-01

    Full Text Available The primary energy consumption in residential buildings is determined by the envelope thermal characteristics, air change, outside climatic data, users’ behaviour and the adopted heating system and its control. The new Italian regulations strongly suggest the installation of centralized boilers in renovated buildings with more than four apartments. This work aims to investigate the differences in primary energy consumption and efficiency among several independent and centralized heating systems installed in Northern Italy. The analysis is carried out through the following approach: firstly building heating loads are evaluated using the software TRNSYS® and, then, heating system performances are estimated through a simplified model based on the European Standard EN 15316. Several heating systems have been analyzed, evaluating: independent and centralized configurations, condensing and traditional boilers, radiator and radiant floor emitters and solar plant integration. The heating systems are applied to four buildings dating back to 2010, 2006, 1960s and 1930s. All the combinations of heating systems and buildings are analyzed in detail, evaluating efficiency and primary energy consumption. In most of the cases the choice between centralized and independent heating systems has minor effects on primary energy consumption, less than 3%: the introduction of condensing technology and the integration with solar heating plant can reduce energy consumption by 11% and 29%, respectively.

  17. Building better boards.

    2004-05-01

    Companies facing new requirements for governance are scrambling to buttress financial-reporting systems, overhaul board structures--whatever it takes to comply. But there are limits to how much good governance can be imposed from the outside. Boards know what they ought to be: seats of challenge and inquiry that add value without meddling and make CEOs more effective but not all-powerful. A board can reach that goal only if it functions as a high-performance team, one that is competent, coordinated, collegial, and focused on an unambiguous goal. Such entities don't just evolve; they must be constructed to an exacting blueprint--what the author calls board building. In this article, Nadler offers an agenda and a set of tools that boards can use to define and achieve their objectives. It's important for a board to conduct regular self-assessments and to pay attention to the results of those analyses. As a first step, the directors and the CEO should agree on which of the following common board models best fits the company: passive, certifying, engaged, intervening, or operating. The directors and the CEO should then analyze which business tasks are most important and allot sufficient time and resources to them. Next, the board should take inventory of each director's strengths to ensure that the group as a whole possesses the skills necessary to do its work. Directors must exert more influence over meeting agendas and make sure they have the right information at the right time and in the right format to perform their duties. Finally, the board needs to foster an engaged culture characterized by candor and a willingness to challenge. An ambitious board-building process, devised and endorsed both by directors and by management, can potentially turn a good board into a great one. PMID:15146740
