    In the years surrounding World War II, solar house heating was seen by many American architects, journal editors, and policymakers as a necessary component of the expansion into suburbia. As the technological and financial aspects of home ownership came to take on broad social implications, design strategies of architectural modernism--including the expansive use of glass, the open plan and façade, and the flexible roof line--were seen as a means to construct suburbs that were responsive to anticipated concerns over materials allocations, over energy-resource scarcity, and over the economic challenges to postwar growth. As this article demonstrates, experiments in passive solar house design were a prominent means for envisioning the suburbs as an opportunity for new kinds of building and new ways of living. The article documents these developments and places them in the context of related efforts to think about the future.

    The Solar Living House is a high-performance solar-powered dwelling designed by a team of faculty and students from the University of Florida, in collaboration with Santa Fe College, the National University of Singapore, and Alachua Habitat for Humanity. The project was designed in accordance with the Solar Decathlon 2015, a research, design, education, and outreach program developed by the U.S. Department of Energy (DOE). The Solar Living House is fundamentally a house for living, centered on people and the activities of daily life while quietly introducing advanced design, construction, and engineering technologies. The 993 square-foot two-bedroom one-bath home was designed to embrace and frame an exterior courtyard space. This courtyard acts as an extension of the interior living spaces, maximizing the spatial potentials of a modest building footprint and introducing natural light into the primary living spaces of the house. Research Outcomes: The Solar Living House advances work on high-performance buildings through three principal technological innovations: wet/dry modular construction, a building automation system, and solar dehumidification systems. Wet / Dry Modular Construction: The house is designed as a series of five modules, including one that is designated as the “wet core.” The wet core consolidates the mechanical systems and bathroom into a single module to reduce plumbing runs, efficiency losses, and on-site construction time. The other four modules are designed to eliminate interior load bearing walls to allow for maximum flexibility in the reconfiguring of the space over time. The modules are designed to meet the structural challenges of both Florida’s hurricanes and California’s earthquakes. Building Automation System: The house is equipped with an integrated building automation system, allowing the houses environmental systems, lights, security systems, and smoke detectors to be programmed, monitored, and controlled through any mobile

    Coastal towns and cities across the Northeastern US, with their high population density, aged utility infrastructure, and unique geography, are increasingly vulnerable to climate change related storm events. In October 2012 superstorm Sandy highlighted the fragility of our current coastal building types and made clear the need for a new model of design and construction which works to understand and mitigate these weaknesses. Dramatic changes in public policy, championed by both The Federal Emergency Management Agency (FEMA) and the National Flood Insurance Program (NFIP) are driving the rebuilding of these shore communities, often resulting in costly renovations, un-sustainable neighborhood configurations and in direct conflict with concurrent government policies such as The American with Disabilities Act (ADA). The SURE HOUSE demonstrates a series of new design solutions to these conflicting public policies and environmental imperatives. At Stevens Institute of Technology, the 2015 Solar Decathlon started with the challenge: Can we design a home for coastal New Jersey that dramatically reduces its energy use while protecting itself from the realities of a changing, more extreme climate? The SURE HOUSE merges the iconic 20th century shore home with 21st century building science. Utilizing innovative renewable energy technologies, a ‘Passive House’ level building envelope, and rugged glass-fiber-composite materials to flood-proof the home, the SURE HOUSE is a high-performance, net-zero-energy home, armored against extreme weather, designed for the contemporary lifestyle of the Jersey Shore and other vulnerable coastal communities. SUSTAINABLE At Stevens, we recognize that energy use in the home and workplace is directly connected to the growing problem of climate change. Reducing our energy consumption by designing higher performing, compact homes that are both functional, comfortable and desirable is the first critical step towards a modern, sustainable

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

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

    Solar drying is one of thermal utilization where radiation energy can be utilized efficiently. Solar drying of all sorts of agricultural products have been thoroughly studied and reported in literature, but brown rice drying system has not yet done as many as other products. The aim of the present study is to investigate the effect of solar radiation on drying house performance and brown rice drying characteristics. A construction of drying house is made from FRP sheets with 30 deg. of root slope faces southern part and inside the drying house is installed a flat bed dryer. The site of construction has 136 deg. 31.4'E in longitude and 34 deg. 43.8N in latitude with 3 m in elevation from sea level. The investigated parameters are global solar radiation, absorbed and net radiation and brown rice drying characteristics. The results showed that in unload condition, the air temperature inside drying house was higher (10 deg. C - 12 deg. C) than ambient air when there was not collector and temperature rise become higher (16 deg. C) when there was a black FRP collector inside drying house. The effect of solar radiation on temperature rise has the trend as a linear function. The heat collection efficiency of drying house with black FRP collector was two times higher (36.9 percent) than that without collector (16.3 percent). These phenomena exhibited significant result of collector utilization to the advantageous condition for a drying purpose [in

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

    2016-01-01

    Full Text Available In the Romanian architectural practice for individual houses in residential areas, designing the architectural object in order to function together with the nature is neglected in the majority of the situations. This happens despite of a great variety of the solar bioclimatic solutions materialized in the traditional houses of all the Romanian geographical regions in a history of over 2000 years of traditional architecture. Unfortunately, in the local real estate realities, other choices are preferred in instead those of the solar bioclimatic architecture. The approach starts with a historical approach, analyzing several examples of traditional houses from all the regions of Romania, in order to identify the traditional bioclimatic solutions used to better adapt to the environment. This constitutes the source of inspiration for the modern cheap type solar bioclimatic houses presented. But a way of thinking should be changed for it, with the help of the Romanian state transformed in financial and legislative realities. These cheap type solar bioclimatic individual houses are destined for the middle class families and involve minimum costs for building and living, creating the best premises to efficiently use one or all of the complementary systems for producing, storage and/or transforming the energy from the environment (using solar, wind, water and/or earth energy.

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

    1995-12-01

    In a new housing estate in Amsterdam in 1995 the regional energy utility (EBA) has integrated a photovoltaic (PV) system (250 kWp) into 63 houses out of 245 houses. The parts of these owner-occupied houses with PV panels are not owned by the occupants. In order to determine which are the motives to buy solar houses and in order to analyze changes in their attitudes questionnaires were sent to potential occupants twice. First to the people who registered for the new housing project (subscribers), and second to the people who bought one of the 245 houses either with or without PV (buyers). The overall conclusion is that PV does not play an important role in the decision making process when buying a new house. It is recommended to study differences in PV preferences and opinions a few years after the buyers have moved to their new houses. 10 figs., 17 tabs., 9 refs., 3 appendices

    Full Text Available In relation to the social Housing’s theme, sustainable requalification interventions on the building heritage in the urban fringes dating back to the WWII postwar play an important role as those are characterized by buildings which offer poor energy performances. These interventions are potentially very effective, although at the same time they raise implementation and management issues, with which it is fundamental to confront, with a view to pursue serious housing and social policies. With this object in view, the introduction of a recently completed intervention in a social housing borough in Savona, also through the use of passive solar systems, offers suggestions and hints for reflection, due to the repeatibility of some adopted solutions and design principles.

    Three plastic film solar dryers covered with different film layers were constructed by modifying a farm vinyl house and studying their performance. The collection efficiency and temperature raising of type C which was covered with double layers of transparent PE and black PVC film was most efficient, followed by B (which was covered with a double layer of transparent PE film) and type A (which was covered with single layer transparent PE film). The inside temperature of type C averaged 18/sup 0/C higher than ambient temperature and its collection efficiency was 31.5% with air flow rate of 3.8 m/sup 3//min. The solar energy collection efficiency of type C was increased in proportion to air flow rate up to 60.2% at 11.3 m/sup 3//min. In a demonstration drying test of red pepper in type C, drying capacity per unit area was 2.5 times higher than that of conventional solar drying on straw mat and drying time shortened to about half.

    In rural China, reducing low-quality fuel consumption and adopting solar technologies can mitigate pollution problems and improve farmers' living conditions. Before advising farmers to convert traditional houses to solar houses, it is necessary to understand their willingness to do so. Based on the theory of planned behaviour (TPB), this study examined nine factors related to farmers' willingness (FW). A survey was conducted in Chongqing with 465 participants. Nine hypotheses were proposed based on literature studies. A binary logistic regression model was constructed to test the data with the SPSS software package. Three of the nine factors had positive and significant impacts on FW, which were quality of life, government commitments and neighbours'/friends' assessments; two factors had negative and significant impacts, which were additional monthly out-of-pocket expenses and switching cost; and the remaining four factors had no significant impacts, which were durability, popularity, timing and local solar market maturity. Based on the findings, suggestions are made to properly introduce solar houses to Chinese farmers and to quickly stimulate market activities. - Highlights: • We study farmers' willingness to convert traditional houses to solar houses. • We have nine hypotheses and test nine associated factors. • Three factors positively and significantly impact farmers' willingness. • Other two factors negatively and significantly impact farmers' willingness. • Remaining four factors do not significantly impact farmers' willingness

    The interest in solar cell technology among Danish house owners is increasing, but there are many considerations to be made before the house owner choose to install solar cells on the house. Major barriers are the solar cell systems' price and appearance. This interdisciplinary development project will show that both aesthetic and economic advantages can be derived from integrating solar cells already when the first sketches of the house are being made. In order to promote utilization of solar cells in Denmark the solutions must be attractive, both economically and aesthetically. Therefore the solar cell solutions in this project are developed in preparation for marketing both as an aesthetic expression and a high-technological, green and prestigious element. (BA)

    This report for the International Energy Agency (IEA) made by Task 10 of the Photovoltaic Power Systems (PVPS) programme takes a look at community-scale photovoltaics. The mission of the Photovoltaic Power Systems Programme is to enhance the international collaboration efforts which accelerate the development and deployment of photovoltaic solar energy. The aim of Task 10 is stated as being to enhance the opportunities for wide-scale, solution-oriented application of photovoltaics in the urban environment. This report provides examples of housing developments and incorporated townships that have integrated multiple stakeholder values into business solutions. The authors are of the opinion that builders, developers, architects and engineers need to consider orientation, aesthetics, load diversity, energy efficiency, grid infrastructure and end use. Residential and commercial building owners or occupants need to consider the design of electric services relative to loads, green image, and economic opportunities such as feed-in tariffs. Local government should give preference to granting permission to high-performance building projects. It is suggested that the finance and insurance sector consider the operational savings in overall debt allowances. System manufacturers and integrators should develop standardised systems. In the emerging PV community market, utilities are quickly gaining awareness of business opportunities. The need for professionals and skilled labour is quoted as having grown as drastically as the PV market itself.

    Full Text Available In this research, a new model was developed and modified with a combined solar heating system which works with solar radiation and electricity. In order to model the system, the outdoor temperature of the location and solar irradiance has been considered. The case study of this research has been done in Porsgrunn City in the south of Norway. The building which was modelled in this research is a passive solar building which is able to store heat by using phase change materials, which are mounted on the floor and release the heat when the temperature of the house decreases. The model of the house was designed based on some assumptions about ambient temperature, solar collector size, transmitting lines length and some specific properties like air density and specific heat. The results of this research show that a solar heating system which is working with electricity can provide a sufficient temperature for the house in winter time. With using the phase change materials in order to have a passive solar building design, an improvement in the temperature inside the house was seen. Based on the simulation results which were achieved, a solar heating system which works with electricity can be an efficient system to heat the house, especially in the winter times.

    1982-09-14

    Within the framework of the Solar House Obdach-project, a system consisting of a ground heat exchanger, a low-temperature collector, a water-glycol/water heat pump and a low-temperature heating system was examined with regard to its suitability as only heat source of a house. With the design chosen (1 m/sup 2/ ground collector area and 0.3 m/sup 2/ low-temperature collector area per 80 W load), a seasonal performance factor of 2.83 could be obtained. About 40% of the low-temperature heat supplied to the heat pump were delivered directly or indirectly (by means of short-term storage in the ground) by the low-temperature collector, whereas about 60% came from the natural sources of energy of the ground (air heat, radiation, precipitation, ground water and slope water). The results obtained are used to verify and improve a computer model design program for ground collectors and ground-coupled storage systems which should help to optimize the design of solar plants, particularly under difficult conditions.

    Solar houses usually have good potential in arid areas. These areas often suffer from not only a shortage of conventional energy sources, but also of potable water supplies. In this study, a solar air-conditioning system including an absorption heat pump, already in production since the early 1980s, is described for potable water production while performing its air-conditioning duty in a solar house. Compiled weather-conditions of the Hurgada area, on the Red Sea coast of Egypt, were employed for the prediction of the system's productivity, if it were installed in such a locality. An evaluation of the system's feasibility has been conducted. (author).

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

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

    Science.gov (United States)

    Barber, Daniel A.

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

    A prototype experimental solar building has been built in the School of Architecture of Valles, Spain. Its final design takes advantage of beneficial climatic effects in order to maintain indoor thermal comfort and to lower auxiliary energy usage. The building has 100 sq m of usable surface, 55 sq m of which are habitable. The remaining area is a greenhouse which is intended for experimental hydroponic cultivation. One of the main features is a thermal regulation system named the ''thermal shield''. This device, placed on the South facade of the building, is composed of a series of plastic translucent layers. Fan-forced air passes through the outer layer and circulates through the special recticular structure of the building to provide daytime heating. A heat absorbing fluid circulating through the innermost layer transfers heat via an exchanger to a storage tank of eutectic salts. The diurnal stored energy can be retrieved to heat the house at night. The thermal shield, which is computer controlled, can also be used to reduce solar gains in summer. (author).

    A preliminary study was undertaken before a large scale project for construction and survey of about a hundred solar houses was launched. The notion of solar house was defined and the use of solar energy (hot water preparation, heating of rooms, heating of swimming pool, or a combination of these possibilities) were examined. A coherent measuring program was set up. Advantages and inconveniences of the large scale project were reviewed. Production of hot water, evaluation of different concepts and different fabrications of solar systems, coverage of the different systems, conservation of energy, failure frequency and failures statistics, durability of the installation, investment maintenance and energy costs were retained as study parameters. Different solar hot water production systems and the heat counter used for measurements are described.

    Indoor pollution by microbes grown in a solar house is studied. It is a reinforced concrete building, having a total floor area of 260m{sup 2}, equipped with a flat type solar collector on the roof and a lighting window on the north, the former having an area of 16m{sup 2} and slanted at 60deg and the latter slanted at 60deg. It is also provided with a semi-underground room, to utilize heat capacity of soil for coolness in summer and warmness in winter. It provides a residential space throughout the year, with no artificial heating or air-conditioning system, naturally ventilated with air taken into the underground room and released out of a triangular shape on the roof. The building is also passively conditioned, being totally insulated with expanded polystyrene. Energy saving is the most important consideration for the solar house, slightly forcing the residents to exercise patience. For this reason, the solar house often smells musty, and pollution with microbes is quantitatively investigated. Microbes evolve more in the underground room than in the space above groun, because of higher humidity in the former. Accelerated ventilation or slight artificial air-conditioning will solve the trouble. 1 refs., 7 figs.

  8. Possible schemes for solar-powered air-conditioning in 2-storey terrace houses

    Chu, C.M.; Bono, A.; Prabhakar, A.

    2006-01-01

    Space cooling is required all year round in the tropics, and probably accounts for a considerable proportion of the cost of electricity. Solar radiation can be channeled into cooling by photovoltaic powered systems and through the relatively new adsorption cycle technology. Two-storey terrace housing appear to have the greatest potential of introducing solar-powered cooling to residential homes. There are two schemes to cool a two-storey terrace housing: 1) By spraying water down the roof a tank, circulated by a pump powered by PV panels on the roof or 2) By replacing the roof with solar hot water collectors and use adsorption cooling chillers to produce air-conditioning for the entire block of terrace houses. In scheme number 1, a preliminary, rough technical evaluation showed that it is possible to pump water to the roof to flow down as a thin film and cool the roof by evaporation to about 40 degree C from about 70 degree C if without water evaporation at the highest insolation rate of the day. Scheme number 2, which uses adsorption chilling technology, requires communal sharing of the air-conditioning facility. The effect of collecting solar heat using the roof is two fold: to absorb solar energy for producing hot water and reducing excess heat input to the house. Preliminary costing demonstrates that solar-powered air-conditioning is within reach of commercialisation, bearing in mind that bulk purchases will dramatically lower the price of a product

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

    Solar cells may be used to convert sunlight directly into electrical energy and into lowgrade heat to be used for large-scale terrestrial solar-energy conversion. Both forms of energy can be utilized if such cells are deployed in close proximity to the consumer (rooftop). Cadmium-sulfide/copper-sulfide (CdS/Cu2S) solar cells are an example of cells which may be produced inexpensively enough to become economically attractive. Cell parameters relevant for combined solar conversion are presented. Critical issues, such as production yield, life expectancy, and stability of performance, are discussed. Systems-design parameters related to operating temperatures are analyzed. First results obtained on Solar One, the experimental house of the University of Delaware, are given. Economic aspects are discussed. Different modes of operation are discussed in respect to the power utility and consumer incentives.

    A number of NESA's (Danish electric power company) customers were offered the use of a solar water heating system for a short period of time. NESA was responsible for the marketing and consultancy service and worked in cooperation with local plumbers in connection with the delivery of the systems. The company contacted 450 households and its representatives visited 25 of these. 4 customers decided to purchase a solar heating system, fourteen decided to think about it, and four declared that they would not buy one. The company had reckoned with 25 purchases. It is concluded that the price of the solar heating systems was too high for prospective customers and the fact that they were not given a special offer had a negative effect. The economic aspect was absolutely the most important for them, especially the length of the payback period on the higher purchase system. Environmental protection aspects came second in their deliberations. NESA has a positive attitude to their customers' use of solar heating plants and recommends that households are offered very high quality consultancy services in connection with marketing. The project is described in detail. (AB)

    Energy Technology Data Exchange (ETDEWEB)

    Lee, T. [Australian National Univ., Canberra, ACT (Australia)

    1994-12-31

    The solarized housing built for what is now the ACT Housing Trust in Canberra in the early 1980`s is revisited to see what lessons can be learned. Several hundred solarized (solar efficient) houses were built by the Federal Government and were the first `passive solar` public housing in Australia. Some houses, due to a combination of slope and expansive soil foundations, were constructed with foil-insulated suspended timber floors instead of concrete slabs and thus had negligible effective thermal mass irrespective of the floor finish chosen by the tenant. It is apparent that many occupants of the early solarized dwellings revisited are not getting the full measure of energy savings and enhanced comfort that the designs allow. In several cases, occupant action in building out their own solar access indicates a low or possible even negative value is placed on their solar heating capabilities. Alternatively, it may indicate that the conceptual extension of living spaces onto a northerly patio, an integral part of many of the original designs, is so attractive as to tempt the owners into extending the roof in translucent material to protect the pleasurable times they have there. This post-occupancy evaluation suggests that acceptance of solar housing should be more closely examined to ensure that future low energy designs fully accommodate the preferred living patterns and needs of their target audience and that further attempts at occupant education are effective in reducing actual home energy consumption.

    2011-12-01

    The paper presents a thermal analysis of a single-floor, solar-powered desert house. The house is air-conditioned and provides all modern comforts and facilities. Electrical power, which drives the entire energy system, is generated by roof-mounted photovoltaic modules. The modules are fixed on special cradles which fold at night to expose the roof to the night sky, thereby enhancing night-time cooling, which is substantial in the desert environment. A detailed dynamic heat transfer analysis is conducted for the building envelope, coupled with a solar radiation model. Application to a typical Middle-Eastern desert site reveals that indeed such a design is feasible with present-day technology; and should be even more attractive with future advances in technology. © 2011 Copyright Taylor and Francis Group, LLC.

    2015-01-01

    Growing global concern regarding climate change motivates technological studies to minimize environmental impacts. In this context, solar water heating (SWH) systems are notably prominent in Brazil, primarily because of the abundance of solar energy in the country. However, SWH designs have not always been perfectly developed. In most projects, the installation option of the solar system only considers the electric power economy aspects and not the particular characteristics of each climatic zone. Thus, the primary objective of this paper is to assess the potential of carbon dioxide reduction with the use of SWH in comparison with electric showers in social housing in several Brazilian climatic zones. The Brazilian government authorities have created public policies to encourage the use of these technologies primarily among the low-income population. The results of this paper indicate that hot climactic regions demonstrate a low reduction of CO 2 emissions with SWH installations. Thus, solar radiation is not useful for water heating in those regions, but it does lead to a large fraction of household cooling loads, implying a demand for electrical energy for air conditioning or requiring the adoption of passive techniques to maintain indoor temperatures below threshold values. -- Graphical abstract: Display Omitted -- Highlights: •Brazil has created public policies to increase the use of solar water heating in social housing. •We have evaluated the potential for reduction of CO 2 emissions installing solar water heating. •We have found that the coldest regions have the greatest potential for reducing emissions. •Passive technologies for thermal comfort in hot climate households are more useful than solar water heating systems

    The application of the all electric ship concept is interesting in the context of several types of warship. Although there it does not pose any major difficulties for simple ships (replenishment ships, amphibious ships) and can be implemented with off-the-shelf technology, its application to combat ships is more ambitious and risky. The renewal of a major part of our frigate fleet in 2008 offers the opportunity to apply this concept. The military and economic advantages have to be demonstrated. Having summarized the programme, the paper discusses the advantages of the all electric concept and examines several areas of technological difficulty that will need to be resolved. Finally, the paper presents work in progress, which will determine whether or not the electric solution is retained for the future multi-mission frigate. (authors)

    2012-01-01

    The objective of this paper is to set propulsion system targets for an all-electric manned helicopter of ultra-light utility class to achieve performance comparable to combustion engines. The approach is to begin with a current two-seat helicopter (Robinson R 22 Beta II-like), design an all-electric power plant as replacement for its existing piston engine, and study performance of the new all-electric aircraft. The new power plant consists of high-pressure Proton Exchange Membrane fuel cells, hydrogen stored in 700 bar type-4 tanks, lithium-ion batteries, and an AC synchronous permanent magnet motor. The aircraft and the transmission are assumed to remain the same. The paper surveys the state of the art in each of these areas, synthesizes a power plant using best available technologies in each, examines the performance achievable by such a power plant, identifies key barriers, and sets future technology targets to achieve performance at par with current internal combustion engines.

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

    In this paper we present a case study for the design of a low cost solar heating system for a popular residence in an isolated rural community in the state of Rio Grande do Norte. This scaling can be extended to several rural communities that are in the same situation in Brazil as well as the wider use of solar power between the low-income people who do not have the benefits of electricity in their homes or want to have a lower cost of electricity. In this context, there are very interesting alternatives, among which is the replacement of electric heating bath water by heating by solar energy. According to several sources the electric shower, as it is now simple and extremely cheap, is the villain of the national electrical system. It is used in peak hours of consumption, something like 10% of electric generating capacity installed in Brazil, forcing many industries to switch off the machines because of the high cost of electricity during this period.

    Projects which relate to the current national thrust toward demonstrating applied solar energy are discussed. The first project has as its primary objective the application of a system comprised of a flat plate collector field, an absorption air conditioning system, and a hot water heating system to satisfy most of the annual cooling and heating requirements of a large commercial office building. The other project addresses the application of solar collector technology to the heating and hot water requirements of a domestic residence. In this case, however, the solar system represents only one of several important technology items, the primary objective for the project being the application of space technology to the American home.

    Highlights: • A new insight into the opaque envelopes of a passive solar house was gained. • Five parts of envelopes, i.e., roof, south/east/west/north walls, were discussed. • Each part of envelopes were analyzed separately rather than treated as a whole. • Ideal properties of materials for each envelope are diverse from one another. • Differences are related to the envelopes’ leading roles as a heater or a cooler. - Abstract: Passive solar houses are effective solutions for minimizing the operating energy of buildings. The building envelopes of passive solar houses exert a significant influence on the degree of indoor thermal comfort. The focus of this study was the construction of high-performance opaque envelopes, i.e., the roof and walls, for a passive solar house, and a new conception of the envelopes from the perspective of the relation between the properties and roles was provided. The discussion was conducted based on a comprehensive range of envelope materials that were distinguished by the thermal conductivity and volumetric heat capacity. For the first time, each part of the envelopes was analyzed separately rather than considered as an entire envelope. By analyzing each envelope individually, the optimum properties of each envelope were found to be distinct from each other. The distinctions are determined by the dominant role of each envelope, which is associated with the location and absorbed solar irradiation. For summer or hot climate applications, when the dominant role is a cooler, the envelope, e.g., the south wall, should consist of materials with high thermal conductivity and large heat capacity; if a heater is the dominant role, the envelope, e.g., the roof, should consist of materials with low thermal conductivity. For winter or cold climate applications, the envelopes with a leading role of a heater or a cooler require materials with high or low thermal conductivity, respectively. Under the guidance of the results, a discussion

    Japanese living houses mainly consist of wooden elements in high-temperature and moist conditions. To modify the hot and humid environment, a conventional old house was partially rebuilt and repaired. Especially in the winter season, a diagnostic thermographic test was used to find deteriorated and leaking parts of interior and exterior walls. Macroscopic deteriorated parts were checked again in detail. The deteriorated element was then removed. During the reconstruction process, a new solar heat and air conditioning system using a silica-gel adsorber and underground water was installed to cool and warm up the living room. Thermography tests of this remodeled house show that room temperature is always constant and mild to human beings, especially in the winter. Temperature and heat flow distribution of flowing air in the living room was measured using thermal net and wire methods. Leaking thermal streak flow of the gap was locally visualized by the IR radiometer and a highly sensitive video camera. It was verified that IR thermography is a useful measuring instrument to check thermal defects of a house.

    The application of advanced electric power system technology to an all electric airplane results in an estimated reduction of the total takeoff gross weight of over 23,000 pounds for a large airplane. This will result in a 5 to 10 percent reduction in direct operating costs (DOC). Critical to this savings is the basic electrical power system component technology. These advanced electrical power components will provide a solid foundation for the materials, devices, circuits, and subsystems needed to satisfy the unique requirements of advanced all electric aircraft power systems. The program for the development of advanced electrical power component technology is described. The program is divided into five generic areas: semiconductor devices (transistors, thyristors, and diodes); conductors (materials and transmission lines); dielectrics; magnetic devices; and load management devices. Examples of progress in each of the five areas are discussed. Bipolar power transistors up to 1000 V at 100 A with a gain of 10 and a 0.5 microsec rise and fall time are presented. A class of semiconductor devices with a possibility of switching up to 100 kV is described. Solid state power controllers for load management at 120 to 1000 V and power levels to 25 kW were developed along with a 25 kW, 20 kHz transformer weighing only 3.2 kg.

    Full Text Available The efficient operation of a passive solar house requires an efficient ventilation system to prevent the loss of energy and provide the required ventilation rates. This paper proposes the use of “breathing architectural members” (BAMs as passive natural ventilation devices to achieve much improved ventilation and insulation performance compared to mechanical ventilation. Considering the importance of evaluating the ventilation and insulation performances of the members, we also propose numerical models for predicting the heat and air movements afforded by the members. The numerical model was validated by comparison with experimental results. The effectiveness of the BAMs was also verified by installation in houses located in an area with warm climate. For this purpose, chamber experiments were performed using samples of the BAMs, as well as numerical simulations to assess natural ventilation and heat load. The main findings of the study are as follows: (1 the one-dimensional chamber experiments confirmed the validity of the numerical models for predicting the heat and air movements afforded by the BAMs. Comparison of the experimental and calculated values for the temperature of air that flowed into the room from outside revealed a difference of less than 5%; (2 observations of the case studies in which BAMs were installed in the ceilings and exterior walls of Tokyo model houses revealed good annual ventilation and energy-saving effects. When BAMs with an opening area per unit area of A = 0.002 m2/m2 were applied to three surfaces, the required ventilation rate was 0.5 ACH (air changes per hour, and this was achieved consistently. Compared to a house with general insulation and conventional mechanical ventilation, heating load was reduced by 15.3%–40.2% depending on the BAM installation points and the differing areas of the house models.

    This report covers a study by Douglas Aircraft Company (DAC) of electrical power systems for advanced transport aircraft based upon an all-electric design concept. The concept would eliminate distributed hydraulic and pneumatic secondary power systems, and feature an expanded secondary electrical power system redesigned to supply power to the loads customarily supplied by hydraulic or pneumatic power. The initial study was based on an advanced 20-kHz electrical power transmission and distribution system, using a system architecture supplied by NASA-Lewis Research Center for twin-engine aircraft with many advanced power conversion concepts. NASA-LeRC later requested DAC to refocus the study on 400-Hz secondary power distribution. Subsequent work was based on a three-engine MD-11 aircraft, selected by DAC as a baseline system design that would provide data for the comparative cost/benefit analysis. The study concluded that the 20-kHz concept produced many expected benefits, and that the all-electric trijet weight savings on hardware redesign would be 2,304 pounds plus a 2.1-percent fuel reduction and resized for a total weight reduction of 11,000 pounds. Cost reductions for a fleet of 800 aircraft in a 15-year production program were estimated at $76.71 million for RDT&E; $2.74 million per aircrat for production; $9.84 million for nonrecurring expenses; $120,000 per aircraft for product support; and $300,000 per aircraft per year for operating and maintenance costs, giving a present value of $1.914 billion saved or a future value of $10.496 billion saved.

    There is a growing interest in the use of fuel cells as a power source for all-electric aircraft propulsion as a means to substantially reduce or eliminate environmentally harmful emissions. Among the technologies under consideration for these concepts are advanced proton exchange membrane (PEM) and solid oxide fuel cells (SOFCs), alternative fuels and fuel processing, and fuel storage. A multidisciplinary effort is underway at the NASA Glenn Research Center to develop and evaluate concepts for revolutionary, nontraditional fuel cell power and propulsion systems for aircraft applications. As part of this effort, system studies are being conducted to identify concepts with high payoff potential and associated technology areas for further development. To support this effort, a suite of component models was developed to estimate the mass, volume, and performance for a given system architecture. These models include a hydrogen-air PEM fuel cell; an SOFC; balance-of-plant components (compressor, humidifier, separator, and heat exchangers); compressed gas, cryogenic, and liquid fuel storage tanks; and gas turbine/generator models for hybrid system applications. First-order feasibility studies were completed for an all-electric personal air vehicle utilizing a fuel-cell-powered propulsion system. A representative aircraft with an internal combustion engine was chosen as a baseline to provide key parameters to the study, including engine power and subsystem mass, fuel storage volume and mass, and aircraft range. The engine, fuel tank, and associated ancillaries were then replaced with a fuel cell subsystem. Various configurations were considered including a PEM fuel cell with liquid hydrogen storage, a direct methanol PEM fuel cell, and a direct internal reforming SOFC/turbine hybrid system using liquid methane fuel. Each configuration was compared with the baseline case on a mass and range basis.

  13. Flywheel in an all-electric propulsion system

    Energy storage is a crucial condition for both transportation purposes and for the use of electricity. Flywheels can be used as actual energy storage but also as power handling device. Their high power capacity compared to other means of storing electric energy makes them very convenient for smoothing power transients. These occur frequently in vehicles but also in the electric grid. In both these areas there is a lot to gain by reducing the power transients and irregularities. The research conducted at Uppsala Univ. and described in this thesis is focused on an all-electric propulsion system based on an electric flywheel with double stator windings. The flywheel is inserted in between the main energy storage (assumed to be a battery) and the traction motor in an electric vehicle. This system has been evaluated by simulations in a Matlab model, comparing two otherwise identical drivelines, one with and one without a flywheel. The flywheel is shown to have several advantages for an all-electric propulsion system for a vehicle. The maximum power from the battery decreases more than ten times as the flywheel absorbs and supplies all the high power fluxes occurring at acceleration and braking. The battery delivers a low and almost constant power to the flywheel. The amount of batteries needed de- creases whereas the battery lifetime and efficiency increases. Another benefit the flywheel configuration brings is a higher energy efficiency and hence less need for cooling. The model has also been used to evaluate the flywheel functionality for an electric grid application. The power from renewable intermittent energy sources such as wave, wind and current power can be smoothened by the fly- wheel, making these energy sources more efficient and thereby competitive with a remaining high power quality in the electric grid

    Outlined herein are measured energy consumption followed for 12 years for a totally electrified solar house with a floor-heating and hot-water heating system. In the solar system, hot water generated by the solar collector is sent, via a surge tank, to a living room, dining room and study to heat their concrete floors, and recycled back to the collector after heating the heat-storage tank for hot water supply. The collector is of plate type, consisting of 6 units, each with a white glass sheet as the heat-collecting membrane for selectively absorbing heat. Its total heat-collecting area is 11.4m{sup 2}. Long-term performance of the solar system installed for floor and hot-water heating in a totally electrified solar house, is analyzed by the measured results collected for 12 years. The house consumes secondary energy of 11.7MWh/year on the average, which is approximately 20% lower that that required for a house of the equivalent size. The solar system has been operated smoothly, to supply 46 and 35% of the required heat for hot-water and floor heating. It is however estimated that annual heat loss reaches 34% in the hot-water heating system, including that in the electric hot-water generator, and prevention of heat loss is one of the major themes for the future system designs. 4 refs., 5 figs.

    A critical issue for solar systems in northern latitudes is the economic profitability. It is often said that the techniques for solar utilisation are expensive and unprofitable. This is, however, not always the case. A new project with 59 low energy terrace houses was carried out in Kolding, Denmark. The houses are designed as ecological buildings with emphasis on total economy based on low operation and maintenance costs, energy conservation and passive/hybrid solar utilisation. Besides direct solar gain through windows, each house has a solar wall of 6-8.5 m{sup 2} on the south facade. The solar walls are used both for heating of ventilation air and for space heating. The solar walls deliver heat to the dwellings during the heating season. To optimise the energy utilisation from the solar walls, the energy is stored internally in building integrated heat storages. Two different new types of prefabricated heat storages are built into the houses. One is an internal concrete wall with embedded ventilation pipes, and the other is a hollow concrete element with integrated stone bed. The heat storages are mainly designed to store solar energy from the day to the evening and the night. Because the solar walls and the heat storages have been a part of the design process from the start, the additional expenses are as low as 30-140 Euro/m{sup 2} solar wall compared with the alternative facade. This is far less than what it costs to add a solar wall on an existing building. Measurements over one year show that the yield of the solar walls is in the range of 115-125 kWh/m{sup 2}/year as expected. With the actual financing, the annual payment of the additional expenses for the solar systems is between 1-6 Euro/m{sup 2} solar wall, while the annual savings are about 5 Euro/year/m{sup 2} (with an energy price of 0.042 Euro/kWh). Dependent on which alternative facade construction the solar wall system is compared with, the profit of the system is in the range of 1 to +4 Euro

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

    The introduction of all-electric propulsion satellites is a game changer in the quest for low-cost access to space. It also raises new questions for satellite manufacturers, operators, and the insurance industry regarding the general risks and specifically the threat of adverse space weather. The issues surrounding this new concept were discussed by research scientists and up to 30 representatives from the space industry at a special meeting at the European Space Weather Week held in November 2014. Here we report on the discussions at that meeting. We show that for a satellite undergoing electric orbit raising for 200 days the radiation dose due to electrons is equivalent to approximately 6.7 year operation at geostationary orbit or approximately half the typical design life. We also show that electrons can be injected into the slot region (8000 km) where they pose a risk of satellite internal charging. The results highlight the importance of additional radiation protection. We also discuss the benefits, the operational considerations, the other risks from the Van Allen radiation belts, the new business opportunities for space insurance, and the need for space situation awareness in medium Earth orbit where electric orbit raising takes place.

    NASA is studying the feasibility of installing 'all-electric' controls in future commercial aircraft, replacing the current hydraulic and pneumatic systems. Planes utilizing such equipment should weigh less and be cheaper to maintain, but might also be susceptible to interference from undesired external electromagnetic fields. Possible sources of these extraneous signals include radio and television broadcasters, two-way communications stations, and radar installations of all kinds. One way to reduce the hazard would be to use fiber-optic cables to carry signals from the cockpit to the various points of use, a concept known as 'fly-by-light' or FBL. However, electrical circuits (PBW, or 'power-by-wire') would still be required at both ends of the cables to perform control functions, so the possibility of harmful interference would remain. Computer models for two different antennas were created in order to find the magnitude of the electric fields which would be generated in the airspace around them while in the transmit mode. The first antenna was a horizontal 'rhombic' used by the Voice of America (VOA) for long-distance short-wave broadcasting. The second antenna was a multi-element 'log-periodic dipole array' (LPDA) of a type often used for two-way radio communications. For each case, a specified amount of power was applied in the computer model, and the resulting electric field intensity was predicted at a variety of locations surrounding the antenna. This information will then be used to calculate the levels of interference which could occur inside an airplane flying in the vicinity of these radiation emitters.

After a long and complex planning phase now measuring and monitoring tasks as well as the realization fo improvement measures are to the fore. This article presents exemplary results of the first year of operation and compare them with the expectations. Self-sufficient operation of the building could be attained between April and October 1993. Here among others hydrogen was successfully produced by photovoltaic supplied electrolysis and was to a large degree used for thermal applications (cooking, heating). The fact that the supply of energy was not self-sufficient all the year round was due to the failure of the fuel cell used to produce electric power again with hydrogen. (orig./BWI) [de

    Evacuating the space connecting cover and absorber significantly improves evacuated tube collector (ETC) performance. So, ETCs are progressively utilised all over the world. The main goal of current study is to explore ETC thermal efficiency in hot and severe climate like Kuwait weather conditions. A collector test facility was installed to record ETC thermal performance for one-year period. An extensively developed model for ETCs is presented, employing complete optical and thermal assessment. This study analyses separately optics and heat transfer in the evacuated tubes, allowing the analysis to be extended to different configurations. The predictions obtained are in agreement with experimental. The optimum collector parameters (collector tube length and diameter, mass flow rate and collector tilt angle) are determined. The present results indicate that the optimum tube length is 1.5 m, as at this length a significant improvement is achieved in efficiency for different tube diameters studied. Finally, the heat generated from ETCs is used for solar cooling of a house. Results of the simulation of cooling system indicate that an ETC of area 54 m2, tilt angle of 25° and storage tank volume of 2.1 m3 provides 80% of air-conditioning demand in a house located in Kuwait.

    The aim of this research is to simulate the performance of a solar chimney located in different macro-zones in Ecuador. The proposed solar chimney model was simulated using a python script in order to predict the temperature distribution and the mass flow over time. The results obtained were firstly compared with experimental data for dry-warm climate. Then, the model was evaluated and tested in real weather conditions: dry-warm, moist-warm and rainy-cold. In addition, the assumed chimney dimensions were chosen according to the literature for the studied conditions. In spite of evaluating the best nightly ventilation, different chimney wall materials were tested: solid brick, common brick and reinforced concrete. The results showed that concrete in a dry-warm climate, a metallic layer on the gap with solid brick in a moist-warm climate and reinforced concrete in a rainy cold climate used for the absorbent wall improve the thermal inertia of the social housing.

    A model house was simulated to reduce the consumption and peak demand for the photovoltaic power generation system, and solar heat air heating and hot water supply system in the solar house. As a type of construction, both wooden construction and reinforced concrete (RC) construction were selected with a total floor area of 125m{sup 2}. All the rooms were equipped with an air conditioner by heat pump from the air thermal source. A solar heat floor heater was simultaneously installed on the first floor. The hot water supply load was 4.8MWh per year. A commercial grid-connected on-site system was applied to the photovoltaic power generation with a 20m{sup 2} wide monocrystalline Si solar cell panel. As for the fluctuation in power load, the peak at the time of rising is more reduced in the RC house than in the wooden house, because the former is smaller in temperature fluctuation than the latter during the intermittence of air conditioning (as per the specified operational schedule). Therefore, the power is more leveled off in the former than in the latter. Between both, difference was hardly made in energy consumption per year. The ratio of dependency was 47% upon the photovoltaic power generation system, while it was 50% and 77%, under the air heating power load and hot water supply power load, respectively, upon the solar heat air heating and hot water supply system, so that both systems were considerably effective in saving the energy. 5 refs., 7 figs., 1 tab.

    Creating the technologies to solve our energy and pollution problems is only one part of the solution. Getting the technologies adopted may be a larger hurdle. This study examines the adoption of a low- or no-cost technology, passive solar housing design, in the United States. Interviews with professionals involved in passive solar supply identified lack of demand as the most important factor, followed by availability, awareness, and economic incentives. Corresponding survey results from homebuyers in one region suggest that lack of demand represents not disinterest, but rather lack of availability when purchasing a home. Conventional homeowners are not familiar with passive solar design, but are predisposed to favor it, especially if it can be incorporated into traditional housing styles. In addition, to the extent that they can learn information to counter the perceptions that passive solar homes are too complicated or there is too little sun in their region, homebuyers would be more willing to purchase a passive solar home. Policy interventions to promote passive solar homes should focus on supply-side incentives as well as information for homebuyers

    Historically the low and moderate income (LMI) market has been underserved by solar photovoltaics (PV), in part due to the unique barriers LMI residents face to participation in the PV market. The intent of this report is to identify the most promising strategies state policymakers might consider to finance PV for LMI customers across three housing types: single family, multi-family, and manufactured housing. The result is a financing matrix that documents the first and second tier financing options states may consider for each housing type. The first tier options were selected based upon their potential impact on LMI PV deployment. Second tier financing approaches could also be used to achieve state policy goals, but may not have as much effect on the relevant LMI market segment. Nevertheless, each financing option comes with tradeoffs that state policymakers may wish to consider when they make decisions about which financing approaches are best suited to achieve their LMI PV deployment goals.

    A regression equation that can calculate the daily accumulated absorption heat of Trombe Wall was given, and the performance estimated chart of Trombe Wall in which the daily unit effect of Trombe Wall can be visually recognized was proposed. The absorption heat was multivariate-analyzed by two variables of solar radiation of that day and the previous day. The data obtained from simulation was used for analysis. The absorption heat was analyzed using the meteorological data at eight spots (Sapporo, Sendai, Niigata, Tokyo, Shizuoka, Kochi, Fukushima, and Kagoshima). In this case, the result of multivariate analysis almost coincided with the simulation result. A chart that predicts the absorption heat of Trombe Wall in eight cities from the daily accumulated global solar radiation of that day and the previous day was then created as the performance estimated chart of Trombe Wall. As a result, the solar radiation of that day little influences the absorption heat when the Trombe Wall increases in thickness. Conversely, the solar radiation of the previous day significantly influences the absorption heat. In future, an equivalent heat loss coefficient will be calculated from the performance estimated chart. 2 refs., 16 figs., 2 tabs.

    This paper examines solar energy development in Malaysia, particularly in relation to the installation of solar Photovoltaic (PV) in residential houses. It analyzes the past activities related to solar energy in Malaysia, in terms of research and developments (R and Ds), the implementations used as well as the national policies for the past 20 years which have pushed the installation of PV in the country. The Feed-In Tariff (FiT) scheme is discussed, showing comparative cost-benefit analysis between the PV installation in houses in the United Kingdom (UK) and Malaysia, and with other investment schemes available in Malaysia. To investigate the awareness of renewable energy policies and incentives, a preliminary survey of the public opinion in Malaysia has been carried out, and an evaluation of public willingness to invest in the FiT scheme by installing the PV on their houses is presented. The cost-benefit analysis shows that the proposed FiT programme is capable of generating good return on investment as compared to the one in the UK, but the return is lower than other investment tools. The survey suggests that most Malaysians are unaware of the government’s incentives and policies towards renewable energies, and are not willing to invest in the FiT scheme. - Highlights: ► Past activities related to solar energy is evaluated and FIT scheme is discussed. ► Financial analysis is presented; public perspective is evaluated. ► The FIT scheme generates higher return for PV installation in Malaysia than in the UK. ► The scheme, however, produces lower return than most investment schemes. ► Malaysians’ awareness levels are low and are not willing to invest in the FIT scheme.

  1. The seed of change in society. Diffusion of solar cell systems in housing by means of pilot projects

    International Nuclear Information System (INIS)

    Van Mierlo, B.C.

    2002-01-01

    The central question in this thesis is: in what way can pilot projects contribute to the diffusion of new sustainable technologies, in particular solar cell systems in housing units. The reason for this is, in the first place, that trials, demonstration projects, practical experiments and market introduction projects are often launched by firms and subsidised by the state. The objective of such projects, referred to here as pilot projects, is in general to prepare the market introduction of new technologies. However, these projects are often realised and financed without much information being available on how they operate: about how they could prepare the market launch and how this function could be optimised. The second reason is that since the end of the 1980s the expectations in the Netherlands in respect of solar cell systems (PV systems) connected to the electricity grid have been high. These systems could have great advantages for the environment and after 2010 could be the most important source of sustainable energy. The government sees housing as the most promising market segment for these systems. It is recognised that certain major bottlenecks have to be solved before a large-scale diffusion is possible. According to the niche approach, the basic starting point of this thesis, this means that the existing social-technological regime needs to change: the rules and infrastructure according to which the existing technologies are, as it were, considered self-evident, and which hinder the introduction of new technologies. Subsidised pilot projects form a protected market niche that can stimulate a change in the regime by learning and by the social embedding of the learning experiences. According to this approach, a protected market niche is a necessary component of state-supported innovation policy if market niches do not arise spontaneously. It is, however, a limited instrument since the ultimate impact on existing regimes depends mainly on external factors

  3. A procedure for analysing energy savings in multiple small solar water heaters installed in low-income housing in Brazil

    International Nuclear Information System (INIS)

    2014-01-01

    Due to government subsidies, Brazil has witnessed an increase in the installation and use of small solar water heating systems in low-income housing projects. Although the initiative has reduced the load curve during peak times due to the reduced use of electric showerheads, measurement and verification (M and V) are needed to validate the savings. M and V procedures should take into account the social and economic variability of low-income housing developments. To improve M and V in low-income housing projects, this paper presents a methodology for identifying homogeneous subgroups based on their energy-saving potential. This research strategy involved a cluster analysis designed to improve the understanding of what energy savers and other influencing factors exist. A case study in Londrina Brazil was undertaken with 200 low-income families. Five clusters, created based on savings potential, were defined. The results showed that only two clusters demonstrated good electricity savings, representing 47% of families. However, two clusters, or 37%, did not provide satisfactory savings, and the other 16% did not provide any consumption history due to previous use of illegal city electricity connection practices. Therefore, studies confirm the need for a detailed measurement of the representative subgroups to assess the influence of human behaviour on potential SWHS-induced savings. - Highlights: • M and V is necessary to improve solar collector-area-based subsidy programmes. • M and V in large-scale sample should contemplate the social and economic variability. • Samples with homogeneous subgroups contribute to a consistent energy-saving M and V. • Solar Water Heaters in some cases may not offer energy saving in a low-income context. • SWH performance decreases with low educational level and difficulty of operation

    Three separate studies have shown operational, weight, and cost advantages for commercial subsonic transport aircraft using an all-electric secondary power system. The first study in 1982 showed that all-electric secondary power systems produced the second largest benefit compared to four other technology upgrades. The second study in 1985 showed a 10 percent weight and fuel savings using an all-electric high frequency (20 kHz) secondary power system. The last study in 1991 showed a 2 percent weight savings using today's technology (400 Hz) in an all-electric secondary power system. This paper will compare the 20 kHz and 400 Hz studies, analyze the 2 to 10 percent difference in weight savings and comment on the common benefits of the all-electric secondary power system.

    Self-sufficiency type houses are outlined. On condition that people gain a certain amount of income in relation with the society, they self-suffice under the given environment, allowing themselves to accept a minimum of industrial products with small environmental load. Ordinary supply from outside of fossil energy and materials which depend on it is minimized. Types are classified into three: energy, energy materials and perfect self-sufficiency. A study project for environment symbiotic houses is progressing which is planned by the Ministry of Construction and Institute of Building Energy Conservation and is invested by a private company. Its target is making a house for halving an environmental load by CO{sub 2}, for the purpose of creating the environment symbiotic house which is nice to and in harmony with the global environment and human beings. As a part of the studies on energy-saving and resource conservation on houses, introduced is a plan of an autonomous house at Izu-Atagawa. The passive method and high thermal-insulation are used for air conditioning, and hot spring water for hot water supply. Electric power is generated by hydroelectric power generation using mountain streams and by solar cells. Staple food is purchased, while subsidiary food is sufficed. 17 refs., 4 figs., 1 tab.

    Persson, Tomas [Hoegskolan Dalarna, Borlaenge (Sweden)

    2004-07-01

    The aim of this study was to investigate how electrically heated houses can be converted to using wood pellet and solar heating. There are a large number of wood pellet stoves on the market. Many stoves have a water jacket, which gives an opportunity to distribute the heat to domestic hot water and a radiator heating system. Three typical Swedish houses with electric resistance heating have been studied. Fourteen different system concepts using wood pellet stoves and solar heating systems have been evaluated. The systems and the houses have been simulated in detail using TRNSYS. The houses have been divided in up to 10 different zones and heat transfer by air circulation through doorways and open doors have been simulated. The pellet stoves were simulated using a recently developed TRNSYS component, which models the start- and stop phases, emissions and the dynamic behaviour of the stoves. The model also calculates the CO-emissions. Simulations were made with one stove without a water jacket and two stoves with different fractions of the generated heat distributed in the water circuit. Simulations show that the electricity savings using a pellet stove are greatly affected by the house plan, the system choice, if the internal doors are open or closed and the desired level of comfort. Installing a stove with a water-jacket connected to a radiator system and a hot water storage has the advantage that heat can be transferred to domestic hot water and be distributed to other rooms. Such systems lead to greater electricity savings, especially in houses having a traditional layout. It was found that not all rooms needed radiators and that it was more effective in most cases to use a stove with a higher fraction of the heat distributed by the water circuit. The economic investigation shows that installing a wood pellet stove without a water jacket gives the lowest total energy- and capital costs in the house with an open plan (for today's energy prices and the

The contribution under consideration reports on the development of an industrial building which is heated entirely by solar energy and meets the standards of passive houses. All working places in the building should be sunny and free of draught. It does not use electrically powered heat pumps or refrigerators. All energy values calculated by simulation were achieved or partly exceeded. The savings in annual operating costs compared to conventional construction in factory buildings is approximately 192,000 Euro per year.

  12. Empowering Distributed Solar PV Energy for Malaysian Rural Housing: Towards Energy Security and Equitability of Rural Communities

    N.A. Ahmad

    2013-02-01

    Full Text Available This paper illustrates on how Malaysia’s development landscapes has been poweredby cheap oil and gas making it dependent and addicted on using large amounts of fossil fuels. As acountry that is primarily depended on fossil fuels for generating power supply, Malaysia needs tocogitate of long-term energy security due to fossil fuel depletion and peak oil issues. Loss of theseresources could leadto thereduction of power generation capacitywhich will threaten the stabilityof the electricity supply in Malaysia. This could potentially influence in an increase in electricitycosts which lead to a phase of power scarcity and load shedding for the country. With the risk ofinterrupted power supplies, rural households, especially those of low-income groups areparticularly vulnerable to the post-effects of a power outage and an inequitable distribution to thepeople. Distributed generation of electricity by solar PVs diminishes the vulnerability of thesehouseholds and can also offer an income to them by feeding the power supply to the national gridthrough Feed-in Tariff scheme. At the moment, the deployment of solar PV installations is still inthe introductory stage in Malaysia, where roof-mounted PV panels are only available to commercialand urban residential buildings. This is due to the lack of a suitable renewable energy policy forrural households and the high cost of the solar PV technology. This paper will put forward ananalysis for incorporating solar photovoltaic on roofs of rural houses by identifying the energyconsumption of these households and the extent to which PVs can alleviate electricity insecurity.The results present significant potential for distributed PV power generation in rural areas inMalaysia which shown a considerable amount of electricity needed to be harvested from roofmountedsolar PV for rural people in Malaysia.

    `Equivalent heat loss factor` used in the simplified load calculation method for the Trombe wall is a version modified to fit a solar house equipped with a Trombe wall. To compute the factor, it is necessary to input the quantities of Trombe wall inner surface absorbed/radiated heat for whose calculation the effect of the delay in solar heat storage by the Trombe wall has to be taken into consideration. The daily summation of the quantities of absorbed/radiated heat can be easily calculated using the day`s and the previous day`s insolation amounts. In this report, the hourly summation of the quantities of Trombe wall surface absorbed/radiated heat is performed by use of two variables which are the day`s and the previous day`s insolation amounts. In calculating the hourly summation of the quantities of absorbed/radiated heat, the daily summation of the quantities of absorbed/radiated heat is first calculated using the chart of predicted lines for the Trombe wall and, based on the data thus obtained, the quantities of absorbed/absorbed heat are divided and assigned to the respective hours and, as the result, approximations are obtained for the calculation of the hourly summation of the quantities of Trombe wall absorbed/radiated heat. A `time-dependent performance prediction curves for the Trombe wall` is proposed, which enables the visual comprehension of the effect of Trombe wall hourly units. 1 ref., 10 figs., 2 tabs.

A first study proposes a prospective analysis of the housing 'stock' in France and the evolution of global energy consumptions and CO 2 emissions by the housing sector, a prospective study of space heating and hot water needs by defining reference scenarios as well as a target scenario for heating consumption (based on the factor 4 of reduction of emissions by 2050), and an assessment of the contribution of the thermal solar energy applied to winter comfort under the form of direct solar floors and passive solar contributions, and applied to hot water by 2050. The contribution of the thermal solar energy is studied within its regulatory context. An analysis of urban forms is also performed to assess the potential of integration of renewable energy solutions in the existing housing stock, and thus to assess the morphological limits of an attempt of generalized solarization of roofs. The second study proposes a detailed identification and assessment of the various sources of primary particles (combustion, industrial processes, mineral extraction and processing, road transport, waste processing and elimination, agriculture, natural sources, forest fires), providing more precise results and methodological complements for some sources. It also proposes a prospective assessment of emissions and identifies the main factors of particle concentrations in urban environment

  18. Retrofitting Domestic Hot Water Heaters for Solar Water Heating Systems in Single-Family Houses in a Cold Climate: A Theoretical Analysis

    Full Text Available One of the biggest obstacles to economic profitability of solar water heating systems is the investment cost. Retrofitting existing domestic hot water heaters when a new solar hot water system is installed can reduce both the installation and material costs. In this study, retrofitting existing water heaters for solar water heating systems in Swedish single-family houses was theoretically investigated using the TRNSYS software. Four simulation models using forced circulation flow with different system configurations and control strategies were simulated and analysed in the study. A comparison with a standard solar thermal system was also presented based on the annual solar fraction. The simulation results indicate that the retrofitting configuration achieving the highest annual performance consists of a system where the existing tank is used as storage for the solar heat and a smaller tank with a heater is added in series to make sure that the required outlet temperature can be met. An external heat exchanger is used between the collector circuit and the existing tank. For this retrofitted system an annual solar fraction of 50.5% was achieved. A conventional solar thermal system using a standard solar tank achieves a comparable performance for the same total storage volume, collector area and reference conditions.

    2016-12-01

    Last year, students working on the SeismoSTEM project at Bergen Community College successfully manufactured and assembled an AS-1 seismometer1. However, issues students encountered were not knowing where to place the TC-1 and AS-1 seismometers, nor how to configure the instruments with a computer for monitoring and measuring earthquakes. Our solution was to purchase a Raspberry Pi 3 model B, which has four USB ports and a Wi-Fi adapter. We then installed the Raspbian operating system that can run jAmaSeis, which allows for the collection and analysis of seismic data. In terms of the shed that was constructed last summer2, we installed roof shingles, as well as a ventilation system to prevent overheating. The seismometers will then be placed on a concrete slab. In the future, we plan on applying a wood varnish around the exterior of the shed, as well as gravel around the shed for water drainage as well as to make it more visually appealing. Moreover, we plan on mounting a 170-W solar panel on the roof to charge a 12-V deep cycle marine battery, which will provide electricity to the system.

    The study of the degradation process occurring in Dye-sensitized Solar Cells (DSCs) is still a hot topic, in view of the final industrialization and application of this class of devices. Currently the long-term analysis of DSCs is carried out on the entire devices, while the monitoring of cell components cannot be performed in situ directly on the materials, but only through indirect methods. In this paper we report on the analysis of two different kinds of Pt counter electrodes through direct measurements performed under real operating conditions, thanks to the use of a home-made microfluidic housing system, which allows the opening and the investigation of the cell components. The counter electrode samples were studied through X-Ray Photoelectron Spectroscopy, Field Emission Scanning Electron Microscopy, Energy Dispersive X-ray Spectroscopy, UV–visible Spectroscopy and Electrochemical Impedance Spectroscopy for a period longer than 1 year. The results showed that the performances of both classes of Pt counter electrodes remained stable for all the investigation period, despite some slight variation of the morphology. DSCs fabricated employing aged counter electrodes exhibited the same photovoltaic performance behavior of reference cells using fresh-produced counter electrodes, thus demonstrating that both class of materials do not undergo degradation during normal operating conditions. - Highlights: • The analysis of Pt counter electrodes for Dye-sensitized Solar Cells was carried out. • Two families of counter electrodes were studied for a period longer than 1 year. • The analyzed samples were investigated in real operating condition. • A small detachment of the Pt clusters in the thermal samples was observed. • The charge transfer properties remained unchanged for all the investigation period.

  5. The impact of the year-on-year variation in the intensity of solar radiation on the energy intensity of low-energy and passive houses

    Full Text Available Solar radiation is a significant segment of heat gains in the operation of buildings. The importance of this segment is highlighted by lowering the energy performance of buildings. The current condition of assessment considers the standard values of solar radiation but these are often very different from the fair values. In the contribution it draws attention to not only to on-year variation in solar fluctuations in the intensity of solar radiation and its significant long-term deviation from the standard values but also to the impact to energy building in reliance to its energy intensity. The attention will be focused also to different values in standards valid in the Czech Republic. This specification of energy assessment of buildings is not only necessary to approximate calculations of real state, but mainly because we can expect more disputes about if a building has declared calculating the parameters of a building with nearly zero-energy or passive house.

    Full Text Available The INCERC Bucharest experimental house is equipped on the Southern façade with a ventilated solar space. The solar space ensures the ventilation of the entire building at a constant rate of 0.60 exchanges / h during the cold season, by inletting the pre-heated space in the greenhouse space. In the hot season the system ensures the building reversible ventilation by providing the fresh air rate by air suction in the building Northern zone, a consequence of the natural draught effect ensured by the solar space. This report presents the experiments performed in the season 2008-2009 and the experimental validation of the mathematical model used in assessing the solar space energy performance in the heating season.

    A single-molecule magnet (SMM) coupled to two normal metallic electrodes can both switch spin-up and spin-down electronic currents within two different windows of SMM gate voltage. Such spin current switching in the SMM tunnel junction arises from spin-selected single electron resonant tunneling via the lowest unoccupied molecular orbit of the SMM. Since it is not magnetically controlled but all-electrically controlled, the proposed spin current switching effect may have potential applications in future spintronics.

    In this study, taking the all factors involved in the energy consumption in residential houses as subjects, the effectiveness of the solar PV system and solar thermal utilizing system in residential houses has been studied by simulating a model residential house considering the improvement of the residual environment in the future. Therefore, a model residual house is assumed, 18 kinds of combinations of construction style, cooling and heating type and solar energy utilizing form are assumed and year round simulation is carried out. The conclusions obtained by the simulation are as follows. The energy consumption in residential houses may decrease greatly by using a solar hot water supplying system. If combined with a solar PV system, the energy consumption in one year is about 8.7 to 9.7 MWh. The combined use of a solar thermal utilizing system and a PV system is more effective to reduce the second-time energy in comparison with the PV system only. 36% of the space heating energy consumption may be decreased by using the solar space heating system, but the decrease effect of the energy consumption of the solar space heating system is smaller than the solar hot water supplying system. 12 refs., 26 figs., 3 tabs.

    2007-01-01

    Environmental protection has now become paramount as evidence mounts to support the thesis of human activity-driven global warming. A global reduction of the emissions of pollutants into the atmosphere is therefore needed and new technologies have to be considered. A large part of the emissions come from transportation vehicles, including cars, trucks and airplanes, due to the nature of their combustion-based propulsion systems. Our team has been working for several years on the development of high power density superconducting motors for aircraft propulsion and fuel cell based power systems for aircraft. This paper investigates the feasibility of all-electric aircraft based on currently available technology. Electric propulsion would require the development of high power density electric propulsion motors, generators, power management and distribution systems. The requirements in terms of weight and volume of these components cannot be achieved with conventional technologies; however, the use of superconductors associated with hydrogen-based power plants makes possible the design of a reasonably light power system and would therefore enable the development of all-electric aero-vehicles. A system sizing has been performed both for actuators and for primary propulsion. Many advantages would come from electrical propulsion such as better controllability of the propulsion, higher efficiency, higher availability and less maintenance needs. Superconducting machines may very well be the enabling technology for all-electric aircraft development

    Full Text Available The increase of people living in large cities and the expansion of new urban areas are keys to defining new sustainable models. It is estimated that about 70% of the EU population lives in urban areas, and it is expected to reach 80% by 2030. Consequently, it is important to find a new concept of buildings that can reduce the total energy consumption. The Solar Decathlon is an international university competition, born in 2002, created by the U.S. State Energy Department (DOE. Students are challenged to design and operate a full-scale, innovative and sustainable house able to exploit solar radiation as its sole energy source. The objective of the competition is to promote research and education in sustainable architecture and solar energy fields. This paper presents an overview on the contribution of LIFT (Interdisciplinary Laboratory of Technical Physics of Roma Tre University to the winning project of the Solar Decathlon Europe 2014 competition: The RhOME for denCity. This project consists of a building properly designed to produce a solar-powered house that is cost-effective, energy-efficient, and attractive.

  13. Experimental Evaluation of Simple Thermal Storage Control Strategies in Low-Energy Solar Houses to Reduce Electricity Consumption during Grid On-Peak Periods

    Directory of Open Access Journals (Sweden)

    Kyoung-Ho Lee

    2015-08-01

    Full Text Available There is growing interest in zero-energy and low-energy buildings, which have a net energy consumption (on an annual basis of almost zero. Because they can generate both electricity and thermal energy through the use of solar photovoltaic (PV and solar thermal collectors, and with the help of reduced building thermal demand, low-energy buildings can not only make a significant contribution to energy conservation on an annual basis, but also reduce energy consumption and peak demand. This study focused on electricity consumption during the on-peak period in a low-energy residential solar building and considers the use of a building’s thermal mass and thermal storage to reduce electricity consumption in summer and winter by modulation of temperature setpoints for heat pump and indoor thermostats in summer and additional use of a solar heating loop in winter. Experiments were performed at a low-energy solar demonstration house that has solar collectors, hot water storage, a ground-coupled heat pump, and a thermal storage tank. It was assumed that the on-peak periods were from 2 pm to 5 pm on hot summer days and from 5 pm to 8 pm on cold winter days. To evaluate the potential for utilizing the building’s thermal storage capacity in space cooling and heating, the use of simple control strategies on three test days in summer and two test days in the early spring were compared in terms of net electricity consumption and peak demand, which also considered the electricity generation from solar PV modules on the roof of the house.

The house, built in Shibuya Ward in Tokyo, has a total floor area of 164m{sup 2}, with a living room, dining room and study heated by the solar system for a total floor area of 35m{sup 2}. A heat-storage tank is provided, dedicated to the DHW system. The solar collector is of flat type, with selectively light-absorbing planes, having a total collector area of 11.46m{sup 2}. The operating conditions of the floor-heating and DHW systems are almost reproduced. It is necessary to take surrounding conditions into consideration; solar radiation in daytime will be overestimated if adjacent buildings are neglected to give higher temperature in the space and on the wall on the south than the observed level. 6 refs., 5 figs., 1 tab.

  18. All-Electrical Spin Field Effect Transistor in van der Waals Heterostructures at Room Temperature

    Science.gov (United States)

    Dankert, André; Dash, Saroj

    Spintronics aims to exploit the spin degree of freedom in solid state devices for data storage and information processing. Its fundamental concepts (creation, manipulation and detection of spin polarization) have been demonstrated in semiconductors and spin transistor structures using electrical and optical methods. However, an unsolved challenge is the realization of all-electrical methods to control the spin polarization in a transistor manner at ambient temperatures. Here we combine graphene and molybdenum disulfide (MoS2) in a van der Waals heterostructure to realize a spin field-effect transistor (spin-FET) at room temperature. These two-dimensional crystals offer a unique platform due to their contrasting properties, such as weak spin-orbit coupling (SOC) in graphene and strong SOC in MoS2. The gate-tuning of the Schottky barrier at the MoS2/graphene interface and MoS2 channel yields spins to interact with high SOC material and allows us to control the spin polarization and lifetime. This all-electrical spin-FET at room temperature is a substantial step in the field of spintronics and opens a new platform for testing a plethora of exotic physical phenomena, which can be key building blocks in future device architectures.

    Complete systems for utilizing solar energy both for hot water preparation and for space heating are available in the FRG today. However, solar technology is unlikely to prevail without governmental support since the plants are still too expensive although there is a principal positive attitude towards solar energy. More knowledge of the process of solar energy utilization is necessary both in the field of building laws, and for building enterprises, architects and planners, if this new form of energy is to succeed.

  2. Social anthropological and interdisciplinary research on the conversion of electrically heated single family houses to heating by combined pellet-solar systems

    International Nuclear Information System (INIS)

    Henning, Annette

    2004-01-01

    The social anthropological research presented here is part of the interdisciplinary research project PESTO, which focuses on the (partial or complete) conversion of single family houses from electric heating to heating by combined pellet-solar heating systems. Basic to this research is the assumption that it is more likely that energy conversions are carried through, and that they are successful on a long-term basis, if the new products are designed to fit as well as possible into the everyday lives of people. The anthropological interest in the project can be divided into two parts; motives for or against a conversion among men and women in Swedish households, and product design and placement in (previously) electrically heated single-family houses. Literature studies and semi-structured qualitative interviews are the main methods used in the anthropological part of the project. During the next 3-year project period, these investigations will be used to support information and marketing, and to formulate recommendations for conversion practice of electrically heated single-family houses to combined pellet-solar heating.

    The article deals mainly with questions relating to the heating of the all-electric Hoch-Ybrig tourist hotel in the Schwyz canton of Switzerland. Situated at an altitude of around 1,500 m above sea level, the hotel is exposed to severe climatic conditions and heated mainly with storage and direct heaters. A number of separate rooms, however, such as restaurant, kitchen, garage, workshops and ancillary rooms, are ventilated by a system combined with Econovent heat recovery units. The heat recovery system saves about 74% of the energy required annually for heating these spaces. The balance is supplied by a central heat store. The design of the heat-recovery system is explained in detail.

    We propose and investigate a spin modulator device consisting of two ferromagnetic leads connected by a two-dimensional topological insulator as the channel material. It exploits the unique features of the topological spin-helical edge states, such that the injected carriers with a non-collinear spin-polarization direction would travel through both edges and show interference effect. The conductance of the device can be controlled in a simple and all-electric manner by a side-gate voltage, which effectively rotates the spin-polarization of the carrier. At low voltages, the rotation angle is linear in the gate voltage, and the device can function as a good spin-polarization rotator by replacing the drain electrode with a non-magnetic material.

    The general electric propulsion orbit-raising maneuver of a spacecraft must contend with four main limiting factors: the longer time of flight, multiple eclipses prohibiting continuous thrusting, long exposure to radiation from the Van Allen belt and high power requirement of the electric engines. In order to optimize a low-thrust transfer with respect to these challenges, the choice of coordinates and corresponding equations of motion used to describe the kinematical and dynamical behavior of the satellite is of critical importance. This choice can potentially affect the numerical optimization process as well as limit the set of mission scenarios that can be investigated. To increase the ability to determine the feasible set of mission scenarios able to address the challenges of an all-electric orbit-raising, a set of equations free of any singularities is required to consider a completely arbitrary injection orbit. For this purpose a new quaternion-based formulation of a spacecraft translational dynamics that is globally nonsingular has been developed. The minimum-time low-thrust problem has been solved using the new set of equations of motion inside a direct optimization scheme in order to investigate optimal low-thrust trajectories over the full range of injection orbit inclinations between 0 and 90 degrees with particular focus on high-inclinations. The numerical results consider a specific mission scenario in order to analyze three key aspects of the problem: the effect of the initial guess on the shape and duration of the transfer, the effect of Earth oblateness on transfer time and the role played by, radiation damage and power degradation in all-electric minimum-time transfers. Finally trade-offs between mass and cost savings are introduced through a test case.

    The electronic and nuclear spin degrees of freedom of donor impurities in silicon form ultra-coherent two-level systems that are potentially useful for applications in quantum information and are intrinsically compatible with industrial semiconductor processing. However, because of their smaller gyromagnetic ratios, nuclear spins are more difficult to manipulate than electron spins and are often considered too slow for quantum information processing. Moreover, although alternating current magnetic fields are the most natural choice to drive spin transitions and implement quantum gates, they are difficult to confine spatially to the level of a single donor, thus requiring alternative approaches. In recent years, schemes for all-electrical control of donor spin qubits have been proposed but no experimental demonstrations have been reported yet. Here, we demonstrate a scalable all-electric method for controlling neutral 31P and 75As donor nuclear spins in silicon. Using coplanar photonic bandgap resonators, we drive Rabi oscillations on nuclear spins exclusively using electric fields by employing the donor-bound electron as a quantum transducer, much in the spirit of recent works with single-molecule magnets. The electric field confinement leads to major advantages such as low power requirements, higher qubit densities and faster gate times. Additionally, this approach makes it possible to drive nuclear spin qubits either at their resonance frequency or at its first subharmonic, thus reducing device bandwidth requirements. Double quantum transitions can be driven as well, providing easy access to the full computational manifold of our system and making it convenient to implement nuclear spin-based qudits using 75As donors.

    The aim of the title inventory is to learn from the experiences with heat pump projects in the Netherlands. Descriptions are given of practical experiences with heat pump applications in the last 15 years in the housing sector. Possible and feasible heat pump system concepts are analyzed and energy balances and energy consumption are calculated. Special attention is paid to the use of solar energy in combination with electric (compression) heat pumps. One of the most important bottlenecks is the method and availability of heat extraction: the choice for the different options is determined by investment costs, permission, regulations, and local conditions. 14 refs., 4 appendices

    Full Text Available Solar energy obtained from the sun is the world most abundant and cheapest source of energy as a cooking fuel. It comes in two forms Concentrated Solar Thermal direct conversion of solar energy to heat that cooks and Solar Photovoltaic PV a conversion of solar energy to electrical then to heat energy the former technology is simple and far cheaper. Despite all these architectural and engineering researches is yet to capture it for indoor cooking because of inability to cook year round due the claimed hindrances by weather condition such as clouds rainfall wind dusty atmosphere and many others. This paper attempted to look into the possibility of cooking year round in Kaduna city. It collected and analyzed ten years climatic data from three different meteorological stations strategically located round the city this showed a low solar radiation in the month of August. It further compared the result with a literature review of solar cooking carried in the same month the findings showed at the peak of each weather hindrance a another element overrides it to give enough minimum energy for cooking a meals. This paper has therefore pointed the potentials of Kaduna city climate for year round use of concentrated solar thermal as a cooking fuel in residential building and further recommends the architectural collaboration with engineers for the direct capturing of solar rays into residential dwelling as a sustainable cooking fuel.

    An all-electrical velocity feedback control to enhance the quality factor of piezoelectric aluminium nitride (AlN)-based microcantilevers and microbridges was implemented. Two alternatives to obtain a velocity-proportional signal were demonstrated depending on the top electrode configuration. For a straightforward electrode design in one-port configuration (i.e. self-actuation and self-sensing), a velocity signal, proportional to the piezoelectric current, was used in the feedback loop by cancelling out the dielectric current electronically. For top electrodes allowing a two-port configuration (i.e. one for actuation and one for sensing), the piezoelectric current is directly extracted and its relationship with velocity is analysed taking the symmetry of the modal shape into account. Standard operational amplifier-based configurations for the feedback circuits were implemented on a printed circuit board. Quality factors were determined from the transient electrical response of the devices. Comparable results were obtained from the displacement spectrum applying a laser Doppler vibrometer. Quality factors as high as 2 × 10 5 , corresponding to an enhancement factor of about 200, were achieved in air for the lowest gain margin achievable before the circuit becomes unstable, making this kind of device more competitive for mass sensor applications due to enhanced spectral resolution.

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

    An evaluation of a variety of efficient water heating strategies for an all-electric single family home located in a mixed-humid climate is conducted using numerical modeling. The strategies considered include various combinations of solar thermal, heat pump, and electric resistance water heaters. The numerical model used in the study is first validated against a year of field data obtained on a dual-tank system with a solar thermal preheat tank feeding a heat pump water heater that serves as a backup. Modeling results show that this configuration is the most efficient of the systems studied over the course of a year, with a system coefficient of performance (COP sys ) of 2.87. The heat pump water heater alone results in a COP sys of 1.9, while the baseline resistance water heater has a COP sys of 0.95. Impacts on space conditioning are also investigated by considering the extra energy consumption required of the air source heat pump to remove or add heat from the conditioned space by the water heating system. A modified COP sys that incorporates the heat pump energy consumption shows a significant drop in efficiency for the dual tank configuration since the heat pump water heater draws the most heat from the space in the heating season while the high temperatures in the solar storage tank during the cooling season result in an added heat load to the space. Despite this degradation in the COP sys , the combination of the solar thermal preheat tank and the heat pump water heater is the most efficient option even when considering the impacts on space conditioning.

    Nowadays, detailed simulation models are widely used to assess thermal performance of buildings, specially during the design stage. However it is usual to report significant differences in predicted thermal performance when confronted with measured data. Therefore the model should be calibrated. In this paper, the PSTAR framework (Subbarao, 1988) is used to calibrate a Energy Plus model of a single-family dwelling. PSTAR method yields a set of renormalization coefficients that offer quantitative interpretation of the predicted vs measured differences. Other experimental tests are used to gain additional insight on how the model should be twicked judiciously. Once calibrated, the model matches three important thermal parameters of the real buildings: heat loss coefficient, thermal mass and solar gains. (Author)

    Recently plug-in hybrid electric vehicles (PHEVs) are emerging as one of the promising alternative to improve the sustainability of transportation energy and air quality especially in urban areas. The all-electric range in PHEV design plays a significant role in sizing of battery pack and cost. This paper presents the evaluation of battery energy and power requirements for a plug-in hybrid electric two-wheeler for different all-electric ranges. An analytical vehicle model and MATLAB simulation analysis has been discussed. The MATLAB simulation results estimate the impact of driving cycle and all-electric range on energy capacity, additional mass and initial cost of lead-acid, nickel-metal hydride and lithium-ion batteries. This paper also focuses on influence of cycle life on annual cost of battery pack and recommended suitable battery pack for implementing in plug-in hybrid electric two-wheelers. -- Research highlights: → Evaluates the battery energy and power requirements for a plug-in hybrid electric two-wheeler. → Simulation results reveal that the IDC demand more energy and cost of battery compared to ECE R40. → If cycle life is considered, the annual cost of Ni-MH battery pack is lower than lead-acid and Li-ion.

    The high voltage energy storage system in plug-in hybrid electric vehicles (PHEVs) is usually a rechargeable type that service a dual purpose, notably to supplement the power delivered by the internal combustion engine, and to provide partial propulsion energy from an off-board source of electricity. The energy storage devices in electric vehicles typically improve vehicle efficiency through engine downsizing and by recapturing braking energy. However, since PHEVs have the ability to recharge their energy storage systems directly from the power grid, the periods of all-electric operation can be extended, thereby reducing the dependence on the internal combustion engine. This is particularly useful in city driving conditions. Developers of PHEV technology are faced with the challenge of choosing the appropriate energy storage battery in order to improve the all-electric drive range. In this study, control strategies were modeled for specific driving load conditions using the Advanced Vehicle Simulator (ADVISOR) software. This paper presented specific control algorithms for PHEV operation for various city driving loads. The optimal design strategy considered the improvement of critical energy storage parameters, overall drive train efficiency, and vehicle performance characteristics. Future trends in the design and development of PHEV drive trains were also presented. 13 figs.

    Despite much anticipation of valleytronics as a candidate to replace the aging complementary metal-oxide-semiconductor (CMOS) based information processing, its progress is severely hindered by the lack of practical ways to manipulate valley polarization all electrically in an electrostatic setting. Here, we propose a class of all-electric-controlled valley filter, valve, and logic gate based on the valley-contrasting transport in a merging Dirac cones system. The central mechanism of these devices lies on the pseudospin-assisted quantum tunneling which effectively quenches the transport of one valley when its pseudospin configuration mismatches that of a gate-controlled scattering region. The valley polarization can be abruptly switched into different states and remains stable over semi-infinite gate-voltage windows. Colossal tunneling valley-pseudomagnetoresistance ratio of over 10 000 % can be achieved in a valley-valve setup. We further propose a valleytronic-based logic gate capable of covering all 16 types of two-input Boolean logics. Remarkably, the valley degree of freedom can be harnessed to resurrect logical reversibility in two-input universal Boolean gate. The (2 +1 ) polarization states (two distinct valleys plus a null polarization) reestablish one-to-one input-to-output mapping, a crucial requirement for logical reversibility, and significantly reduce the complexity of reversible circuits. Our results suggest that the synergy of valleytronics and digital logics may provide new paradigms for valleytronic-based information processing and reversible computing.

  8. Manifestations of geometric phases in a proton electric-dipole-moment experiment in an all-electric storage ring

    Silenko, Alexander J.

    2017-12-01

    We consider a proton electric-dipole-moment experiment in an all-electric storage ring when the spin is frozen and local longitudinal and vertical electric fields alternate. In this experiment, the geometric (Berry) phases are very important. Due to the these phases, the spin rotates about the radial axis. The corresponding systematic error is rather important while it can be canceled with clockwise and counterclockwise beams. The geometric phases also lead to the spin rotation about the radial axis. This effect can be canceled with clockwise and counterclockwise beams as well. The sign of the azimuthal component of the angular velocity of the spin precession depends on the starting point where the spin orientation is perfect. The radial component of this quantity keeps its value and sign for each starting point. When the longitudinal and vertical electric fields are joined in the same sections without any alternation, the systematic error due to the geometric phases does not appear but another systematic effect of the spin rotation about the azimuthal axis takes place. It has opposite signs for clockwise and counterclockwise beams.

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

    PEP stands for 'Promotion of European Passive Houses' and is a consortium of European partners, supported by the European Commission, Directorate General for Energy and Transport. In this working paper an overview is given of Passive House solutions. An inventory has been made of Passive House solutions for new build residences applied in each country. Based on this, the most common basic solutions have been identified and described in further detail, including the extent to which solutions are applied in common and best practice and expected barriers for the implementation in each country. An inventory per country is included in the appendix. The analysis of Passive House solutions in partner countries shows high priority with regard to the performance of the thermal envelope, such as high insulation of walls, roofs, floors and windows/ doors, thermal bridge-free construction and air tightness. Due to the required air tightness, special attention must be paid to indoor air quality through proper ventilation. Finally, efficient ((semi-)solar) heating systems for combined space and DHW heating still require a significant amount of attention in most partner countries. Other basic Passive House solutions show a smaller discrepancy with common practice and fewer barriers have been encountered in partner countries. In the next section, the general barriers in partner countries have been inventoried. For each type of barrier a suggested approach has been given. Most frequently encountered barriers in partner countries are: limited know-how; limited contractor skills; and acceptation of Passive Houses in the market. Based on the suggested approaches to overcoming barriers, this means that a great deal of attention must be paid to providing practical information and solutions to building professionals, providing practical training to installers and contractors and communication about the Passive House concept to the market.

  14. Tech House

    1978-01-01

    The members of the Swain family- Dr. Charles "Bill" Swain, wife Elaine, daughter Carol, 17, son "Chuck", 12, and dog Susie have an interesting assignment. They are active participants in an important NASA research program involving the application of space-age technology to home construction. b' Transplanted Floridians, the Swains now reside in NASA's Tech House, loatedat Langley Research Center, Hampton, Virginia. Their job is to use and help evaluate the variety of advanced technology systems in Tech House. A contemporary three-bedroom home, Tech House incorporates NASA technology, the latest commercial building techniques and other innovations, all designed to reduce energy and water consumption and to provide new levels of comfort, convenience, security and fire safety. Tech House equipment performed well in initial tests, but a house is not a home until it has people. That's where the Swains come in. NASA wants to see how the various systems work under actual living conditions, to confirm the effectiveness of the innovations or to determine necessary modifications for improvement. The Swains are occupying the house for a year, during which NASA engineers are computer monitoring the equipment and assembling a record of day-to-day performance. . Tech House is a laboratory rather than a mass production prototype, but its many benefits may influence home design and construction. In a period of sharply rising utility costs, widespread adoption of Tech House features could provide large-scale savings to homeowners and potentially enormous national benefit in resources conservation. Most innovations are aerospace spinoffs: Some of the equipment is now commercially available; other systems are expected to be in production within a few years. Around 1980, a Tech House-type of home could be built for $45-50,000 (1 976 dollars). It is estimated that the homeowner would save well over $20,000 (again 1976 dollars) in utility costs over the average mortgage span of 20 years.

    2014-01-01

    The Hood River Passive Project was developed by Root Design Build of Hood River Oregon using the Passive House Planning Package (PHPP) to meet all of the requirements for certification under the European Passive House standards. The Passive House design approach has been gaining momentum among residential designers for custom homes and BEopt modeling indicates that these designs may actually exceed the goal of the U.S. Department of Energy's (DOE) Building America program to "reduce home energy use by 30%-50% (compared to 2009 energy codes for new homes). This report documents the short term test results of the Shift House and compares the results of PHPP and BEopt modeling of the project. The design includes high R-Value assemblies, extremely tight construction, high performance doors and windows, solar thermal DHW, heat recovery ventilation, moveable external shutters and a high performance ductless mini-split heat pump. Cost analysis indicates that many of the measures implemented in this project did not meet the BA standard for cost neutrality. The ductless mini-split heat pump, lighting and advanced air leakage control were the most cost effective measures. The future challenge will be to value engineer the performance levels indicated here in modeling using production based practices at a significantly lower cost.

    This short communication paper focuses on the renewable heat incentive (RHI) scheme in the United Kingdom (UK); and in particular, on its implication on domestic installations of solar thermal systems (STSs). First, a short review on the STS in the UK is provided. Then, a detailed description of the RHI is discussed. A financial analysis is presented afterwards, analysing the impact of the RHI scheme on the applicants, in terms of the net present value and the internal rate of return. From the financial analysis it has been found that the RHI scheme for domestic installations is only attractive if a longer period of RHI payment, i.e. 17 years, or a higher RHI rate i.e. £0.32 per kW h is implemented. The current proposal from the UK government is not financially viable, and as a result, it may hinder the penetration of domestic solar thermal systems in the residential sector in the UK. - Highlights: • A short review on solar thermal system (STS) is presented. • The renewable heat incentive (RHI) scheme is discussed. • A financial analysis is evaluated under the RHI scheme in the UK. • The analysis indicates the current proposal is not desirable to consumers

    GWS takes plans for a new home and subjects them to intensive computerized analysis that does 10,000 calculations relative to expected heat loss and heat gain, then provides specifications designed specifically for each structure as to heating, cooling, ventilation and insulation. As construction progresses, GWS inspects the work of the electrical, plumbing and insulation contractors and installs its own Smart House Radiant Barrier. On completion of the home, GWS technicians use a machine that creates a vacuum in the house and enables computer calculation of the air exchanged, a measure of energy efficiency. Key factor is the radiant barrier, borrowed from the Apollo program. This is an adaptation of a highly effective aluminized heat shield as a radiation barrier holding in or keeping out heat, cold air and water vapor.

    This report is for the results of fiscal 1979 on a solar cooling/heating and hot-water supply system for newly-built private housing. The research reports for fiscal 1974 to 1978 are as reported so far; for example, the research on energy-saving construction including thermal insulation method was used in an experimental housing completed in fiscal 1976. The solar heat collecting device was built in the experimental housing by increasing the scale of and utilizing the heat collecting device of a vacuum glass tube type on which research was done before fiscal 1975. The absorption refrigerating machine incorporated in the housing was of a forced circulation type which was high in temperature stability using the result of the research carried out until then. In fiscal 1979, as in fiscal 1978, one year residential experiment was conducted in which a family of a couple and two children lived in a house under an improved system as a result of a system variation and the like, and made an evaluation on the performance. Simultaneously, a control management system was developed in which a micro-computer was introduced for the purpose of improving the system performance, with the operation carried out under the micro-computer control. In addition, a fundamental experiment was also completed concerning a long-term heat accumulation by underground heat reserve. (NEDO)

    The Brazilian land receives a great amount of solar radiation all over the year, therefore, because both the culture and practical aspects, Brazilians use in a non-moderate way the electricity to boil the water for human bath in the rural homes, in the lower income residences even at part of the medium class homes. That happens due to the very low price of an electrical shower, about US$ 6,5. In fact, that way of heating water is largely used because, besides the very low electrical shower price, it is not necessary to install a complete hot water both hydraulic and electrical building systems, but just both single hydraulic pipes and electrical devices. On the other hands, at rural regions where the electricity does not achieve the rural people uses firewood in order to get hot water for human bath. At the rural places the use of electrical showers has meaning an increase in the electrical transformers powers, heavier electrical transmission rural lines, with greater prices and, at the urban zones, the use of electrical showers in the lower social classes has contributed to a more expressive electrical load at the nacional electrical system load peck, between 5:30 to 8:30 a.m. The public administration, mostly, does not take into account both social, economic and environmental costs in order to think about the electricity offer. The solar heating systems, generally used in Brazil, conserves the same reservoirs used in France at 1880. Therefore, this paper presents some technical subsidies applied to rural homes, even to lower income people's homes aiming to stimulate the Brazilian public authorities to make a public police to facilitate both the industrialization and dissemination of solar heating systems, appropriate to the rural area, with lower costs, compounded by good technology equipment, with guarantee of lasting and quality.

    The home shown at right is specially designed to accommodate solar heating units; it has roof planes in four directions, allowing placement of solar collectors for best exposure to the sun. Plans (bottom) and complete working blueprints for the solar-heated house are being marketed by Home Building Plan Service, Portland, Oregon. The company also offers an inexpensive schematic (center) showing how a homeowner only moderately skilled in the use of tools can build his own solar energy system, applicable to new or existing structures. The schematic is based upon the design of a low-cost solar home heating system built and tested by NASA's Langley Research Center; used to supplement a warm-air heating system, it can save the homeowner about 40 percent of his annual heating bill for a modest investment in materials and components. Home Building Plan Service saved considerable research time by obtaining a NASA technical report which details the Langley work. The resulting schematic includes construction plans and simplified explanations of solar heat collection, collectors and other components, passive heat factors, domestic hot water supply and how to work with local heating engineers.

  19. Online Energy Management of Plug-In Hybrid Electric Vehicles for Prolongation of All-Electric Range Based on Dynamic Programming

    Directory of Open Access Journals (Sweden)

    Zeyu Chen

    2015-01-01

    Full Text Available The employed energy management strategy plays an important role in energy saving performance and exhausted emission reduction of plug-in hybrid electric vehicles (HEVs. An application of dynamic programming for optimization of power allocation is implemented in this paper with certain driving cycle and a limited driving range. Considering the DP algorithm can barely be used in real-time control because of its huge computational task and the dependence on a priori driving cycle, several online useful control rules are established based on the offline optimization results of DP. With the above efforts, an online energy management strategy is proposed finally. The presented energy management strategy concerns the prolongation of all-electric driving range as well as the energy saving performance. A simulation study is deployed to evaluate the control performance of the proposed energy management approach. All-electric range of the plug-in HEV can be prolonged by up to 2.86% for a certain driving condition. The energy saving performance is relative to the driving distance. The presented energy management strategy brings a little higher energy cost when driving distance is short, but for a long driving distance, it can reduce the energy consumption by up to 5.77% compared to the traditional CD-CS strategy.

The report includes the system analysis result (collection of existing technical data, analysis of weather conditions, profitability assessment, concept design of the primary experimental house), and the research result on equipment and materials (view and evaluation of existing technologies, selective transparent and absorption materials, the primary prototype solar heat collector model, refrigerator). As the study result, the spheroidal experimental house was adopted. The solar heat utilization system is a central air-conditioning equipment composed of heating by hot water obtained from the solar heat collector, and cooling by absorption refrigerator. Heat collection efficiencies were measured for (1) stainless steel substrate collector, (2) copper substrate collector, and (3) glass pipe collector prepared as prototype collectors. (2) was higher in heat collection efficiency than (1). The efficiency of (3) hardly increased by rise in heat collection temperature due to vacuum structure and selective absorption membrane. Further measurement of such characteristics is necessary at higher temperatures. (NEDO)

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

    Transport activity has been a key facilitator and driver of economic prosperity in Lithuanian (hereinafter LIT) and it is likely to continue to grow. It can produce both positive and negative effects on the quality of life and the environment depending on country-specific circumstances. This research paper sets the stage for a look at the LIT passenger vehicle fleet and its transition towards sustainable mobility through the use of all-electric vehicles. The large multi purpose vehicle from French car-maker Renault, model Renault Espace, was used for test drives, according ECE R101 (urban cycle) requirements. The conventional spark ignited internal combustion engine of the vehicle was replaced by the electric one and equipped with the new generation LiFePO 4 Lithium-ion rechargeable batteries. Three streets of Kaunas city (LIT) with different categories B1, B2 and C2 were selected for the test procedure. Estimation of the power demand (depending on displacement and daytime) and evaluation of battery performance characteristics were discussed in detail. Calculation of the driving distance of the one charge of the traction battery estimates several driving conditions and variation of the mass of the investigated vehicle. Comparison of consumption of different fuel grades for 1 km showed that costs of electric power driven vehicle is 4 times as low as with A95 grade petrol and 2.4 times as low as with diesel fuel. - Highlights: • This paper examines the perspectives for electric vehicles use in Lithuania. • We used standardized test procedure UN ECE R101 (urban cycle). • The study found that the BEVs (battery-only electric vehicles) can cover approximately 75% of all daily driving. • Inspection of the results highlights the importance of BEVs introduction. • We have shown that battery-only electric vehicles are economically rational

    Spin-based electronics or ‘spintronics’ has been a topic of interest for over two decades. Electronic devices based on the manipulation of the electron spin are believed to offer the possibility of very small, non-volatile and ultrafast devices with very low power consumption. Since the proposal of a spin-field-effect transistor (SpinFET) by Datta and Das in 1990, many attempts have been made to achieve spin injection, detection and manipulation in semiconductor materials either by incorporating ferromagnetic materials into device architectures or by using external magnetic fields. This approach has significant design complexities, partly due to the influence of stray magnetic fields on device operation. In addition, magnetic electrodes can have magneto-resistance and spurious Hall voltages that can complicate device performance. To date, there has been no successful report of a working Datta-Das SpinFET. Over the last few years we have investigated an all-electric means of manipulating spins, one that only relies on electric fields and voltages and not on ferromagnetic materials or external magnetic fields. We believe we have found a pathway toward this goal, using in-plane side-gated quantum point contacts (QPCs) that rely on lateral spin-orbit coupling to create spin polarization. In this paper we discuss several aspects of our work, beginning with our finding what we believe is nearly complete spin-polarization in InAs QPCs by purely electrical means, our theoretical work to understand the basic mechanisms leading to that situation (asymmetric lateral confinement, lateral spin-orbit coupling and a strong e-e interaction), and our recent work extending the effort to GaAs and to dual QPC systems where one QPC acts as a polarizer and the other as an analyzer.

    A pilot program was developed to provide the housing industry with a means to field test innovative technologies, products and building systems, and to evaluate their overall performance. Under Canada`s Advanced House Program, ten demonstration houses were designed, built and monitored. Ottawa`s Innova House, was one of the ten houses built for this program. The innovative energy saving features of the house included (1) air distribution with small diameter ducts and an electronically commutated motor, a 2.6 kW grid-connected photovoltaic system, (3) an energy recovery ventilator (ERV) with free-cooling mode, (4) a 94 per cent efficient integrated gas heating and hot water system, (5) airtight drywall construction, (6) CFC-free exterior insulation, (7) a natural-gas-engine heat pump for air conditioning, (8) a prototype sealed combustion gas range and clothes dryer, and (9) a manifold plumbing system to conserve water. It was designed to consume one half of the energy consumed in an R-2000 home and one third of the energy of a conventional house. Several of the mechanical elements did not perform at expected levels, (lower than expected efficiencies from the heating and cooling systems and a malfunctioning ERV), nevertheless, overall performance of the house was still very close to the targets. The construction and operation of the house was described. tabs., figs.

  19. Essays on Housing Markets

    DEFF Research Database (Denmark)

    Bäckman, Claes

    In Denmark and in many countries around the world, housing markets are of considerable importance for households and policy-makers alike. As the boom and bust in the US and Danish housing market so aptly demonstrated, disruptions in the housing market potentially have wide-ranging consequences...... for individual households and for the aggregate economy. Housing is important because we all have to live somewhere, but also because it serves as a considerable source of both wealth and debt. As such, housing market policy can not only create vast benefits for many, but can also have substantial negative...... impacts for all, and should therefore be a topic of major interest for economists and policy makers alike. This Ph.D. thesis, entitled “Essays on Housing Markets”, analyzes the Danish housing market during the 2000s, with a focus on how policy changes affected house prices and how changes in house prices...

  20. The bishops and housing.

    According to Catholic social teaching, housing is not a commodity but a human right. To ensure that all people--especially low-income elderly and other vulnerable populations--have access to affordable housing, the church has established a variety of programs, services, and advocacy efforts. Much of this work is based on key concepts: preserving existing housing stock, creating new programs to provide more options for the underserved, empowering residents and communities to deal with housing issues, establishing partnerships to make organizations' efforts more successful, making housing affordable, and ending discrimination in housing. Although church ministries, community groups, the private sector, and other players must work together to find solutions to the housing crisis, federal leadership is essential. Especially with the housing affordability gap growing and the U.S. population aging, the federal government must provide the resources, leadership, and direction for effective housing solutions.

  4. Bandwidth based methodology for designing a hybrid energy storage system for a series hybrid electric vehicle with limited all electric mode

    Science.gov (United States)

    Shahverdi, Masood

    The cost and fuel economy of hybrid electrical vehicles (HEVs) are significantly dependent on the power-train energy storage system (ESS). A series HEV with a minimal all-electric mode (AEM) permits minimizing the size and cost of the ESS. This manuscript, pursuing the minimal size tactic, introduces a bandwidth based methodology for designing an efficient ESS. First, for a mid-size reference vehicle, a parametric study is carried out over various minimal-size ESSs, both hybrid (HESS) and non-hybrid (ESS), for finding the highest fuel economy. The results show that a specific type of high power battery with 4.5 kWh capacity can be selected as the winning candidate to study for further minimization. In a second study, following the twin goals of maximizing Fuel Economy (FE) and improving consumer acceptance, a sports car class Series-HEV (SHEV) was considered as a potential application which requires even more ESS minimization. The challenge with this vehicle is to reduce the ESS size compared to 4.5 kWh, because the available space allocation is only one fourth of the allowed battery size in the mid-size study by volume. Therefore, an advanced bandwidth-based controller is developed that allows a hybridized Subaru BRZ model to be realized with a light ESS. The result allows a SHEV to be realized with 1.13 kWh ESS capacity. In a third study, the objective is to find optimum SHEV designs with minimal AEM assumption which cover the design space between the fuel economies in the mid-size car study and the sports car study. Maximizing FE while minimizing ESS cost is more aligned with customer acceptance in the current state of market. The techniques applied to manage the power flow between energy sources of the power-train significantly affect the results of this optimization. A Pareto Frontier, including ESS cost and FE, for a SHEV with limited AEM, is introduced using an advanced bandwidth-based control strategy teamed up with duty ratio control. This controller

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

    Highlights: • A hybrid system with a wind turbine, photovoltaic panels and a fuel cell was studied. • 3 kW wind turbine, 17.97 m 2 photovoltaics, 1.2 kW fuel cell and 4.7 kW electrolyzer was used. • The system can meet the entire demand of a residential house in Ankara, Turkey. • Only exception is in November, when the energy lack can be compensated from the grid. - Abstract: Renewable energy use in the world increases year by year. However, in many cases it is not possible to cover the electrical energy need of even a single house using only one renewable energy resource due to its intermittent nature. At this point, hybrid systems are applied to overcome this problem. This study focuses on the combination of photovoltaic solar panels, a small scale wind turbine, an electrolyzer and a proton exchange membrane fuel cell hybrid system for electrical power generation for an average house of 150 m 2 located at İncek region of Ankara, Turkey. Solar and wind energies were used as primary sources and a proton exchange membrane fuel cell is used as the backup power. The hybrid system was modeled and the results indicate that the use of the selected wind turbine with a 3 kW capacity along with photovoltaic panels with 17.97 m 2 area is sufficient to provide the required 5 h operation of the electrolyzer, which in turn provides the necessary hydrogen and oxygen to the fuel cell. Since the daily energy needed by the investigated house was taken as 5 kW h, the fuel cell with a net power output of 1 kW supplies all electrical demand with its 5 h operation. The outcomes show that the hybrid system is capable to provide all electrical need of the house all year round, except November. The electrical energy production of the proposed system is considerably higher than the demand in many months and this surplus electricity can be used in order to support the cooling and heating system of the considered house.

    1990-01-01

    The feasibility of directly converting solar energy for crew water heating on the Space Station Freedom (SSF) and other human-tended missions such as a geosynchronous space station, lunar base, or Mars spacecraft was investigated. Computer codes were developed to model the systems, and a proof-of-concept thermal vacuum test was conducted to evaluate system performance in an environment simulating the SSF. The results indicate that a solar water heater is feasible. It could provide up to 100 percent of the design heating load without a significant configuration change to the SSF or other missions. The solar heater system requires only 15 percent of the electricity that an all-electric system on the SSF would require. This allows a reduction in the solar array or a surplus of electricity for onboard experiments.

    2011-01-01

    Full Text Available Two themes are evident in housing research in Ghana. One involves the study of how to increase the number of dwellings to correct the overall housing deficit, and the other focuses on how to improve housing for slum dwellers. Between these two extremes, there is relatively little research on why the existing buildings are poorly maintained. This paper is based on a review of existing studies on inadequate housing. It synthesises the evidence on the possible reasons for this neglect, makes a case for better maintenance and analyses possible ways of reversing the problem of inadequate housing.

    System of the house is outlined, and warming performance and photovoltaic power generation system energy performance are taken up. It is a one-storied meeting hall situated in an apartment area, whose heat loss factor is 2.59kcal/m2hdegC. Ninety hybrid solar cells provided with circulating air heat collectors are installed on the east-side of the roof, interconnected to the commercial power system. In the daytime in summer, the house is fully insulated from solar radiation, with the room temperature kept a little lower than the open air temperature. The range of daily change in the room temperature is narrow, providing a comfortable residential space. When the windows are opened in the evening, cool air comes into the room to replace the warm air inside, reducing the difference in temperature between the inside and outside of the room. In winter, insolation time is short on the east side of the roof which finds itself out of the sun. Under the circumstances, the system outputs but a little and the quantity sold is quite small in winter. But, in summer, sale of power can be practicable, thanks to exposure to sufficient sunshine. The inverter rated at 3.5kW attains a 90% or higher operating rate in the presence of an input of power of 0.5kW or more. 4 refs., 10 figs.

In the study on heat transfer and heat storage system equipment, the medium-scale latent heat type heat storage tank (1 x 10{sup 4}kcal in thermal capacity, 8 x 10{sup 3}kcal/h in thermal output) using ammonium alum was prepared. For a preventive mechanism against supercooling, reconsideration of structure of a crystal nucleus formation plate was necessary. In the study on refrigerator driven by Rankine cycle engine, the prototype compressor more than 3,000kcal/h in refrigeration capacity was fabricated. Construction of the experimental house and trial operation of the cooling/heating system were promoted. (NEDO)

    This report describes the fiscal 1974 R and D result on solar cooling/heating and hot water supply systems for apartment houses. In system analysis, the system plan was selected through basic data survey, modeling by combining some kinds of such systems and energy flow calculation. On solar heat collector, theoretical analysis was made on a stationary plane collector, and study was made on cover glass material and absorption surface performances. On Rankine's engine, studies on advanced selective absorption film, transmissive film, prevention of heat radiation and converging collector were necessary. As solar heat driving refrigerators, absorptive one and Rankine's one were promising. As heat media for refrigerators, R-11 and 113, and R-114 and 11 were suitable for turbo one and displacement one, respectively. Since a displacement compressor is featured by high-efficiency lower-speed operation than that of turbo one without any constraint, its direct connection with a motor or generator is possible. Screw compressor belonging to displacement one was promising. Rotary displacement one was also promising in a small-capacity range within 20-50RT. (NEDO)

    1999-01-01

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

    A nationwide investigation of radon levels in Syrian houses was carried out during the period 1991-1993. Passive radon diffusion dosemeters using polycarbonate detectors were distributed in houses all over Syria. Detectors were subjected to electrochemical etching to reveal latent tracks of alpha particles. The mean radon concentration in Syrian houses was found to be 45 Bq m -3 with some values several times higher. This investigation indicated that there were a few houses in Syria that require remedial action. Most houses that have high levels of radon were found in the southern area, especially in the Damascus governorate. The study also indicated that radon concentrations were higher in old houses built from mud with no tiling. (author)

    A description of a demonstration project, located near Viborg in Denmark, involving a 400 m{sup 2} house with low energy consumption which has a 200 m{sup 2} living/working area, a 240 m{sup 2} mobile insulated glass facade and a solar greenhouse of 200 m{sup 2} which in addition to plant production can be used for recreational purposes. Humidity in the greenhouse is regulated by heat pumps condensing the water-laden air and thus producing hot water for space heating. The heat pumps maintain a 70% relative humidity in the greenhouse and surplus heat to the amount of 300 kWh/m{sup 2} of glass facade area is produced annually. Excess heat to the amount of 75.000 kWh is available for space heating in adjoining houses. The glazed roof of the house and greenhouse is constructed of two layers of tempered glass. The 20 cm space between the layers, when filled with polystyrene beads, provides thermal insulation equal to that of traditionally insulated outer house-walls. The beads can be sucked in and out of the roof space and can also be used for shading during the summer. It is concluded that the house (400 m{sup 2}) consumes the same quantity of energy as houses of a similar size and at the same time produces 300 kWh/m{sup 2} p.a. with the glass south facade, corresponding to what a solar collector produces per m{sup 2}.

    Over the last decade, climate change has moved from being the concern of few to a widely recognized threat to humanity itself and the natural environment. The 1990s were the warmest decade on record, and ever-increasing atmospheric levels of greenhouse gases such as carbon dioxide (CO/sub 2/), could, if left unchecked lead to serious consequences globally, including increased risks of droughts, floods and storms, disruption to agriculture, rising sea levels and the spread of disease. The contribution of anthropogenic emissions of carbon dioxide has been recognized as the principal cause of the atmospheric changes that drive these climate trends. Globally, buildings are the largest source of indirect carbon emissions. In 2000, the UK Royal Commission on Environmental Pollution estimated that in order to stabilise carbon emissions at levels, which avoid catastrophic alterations in the climate, we would have to reduce emissions from the built environment by at least 60% by 2050 and 80% by 2100 relative to 1997 levels. Studies of the Oxford Ecohouse have demonstrated that it is not difficult to reduce carbon emissions from houses by 60% or more through energy efficiency measures, but it is only possible to reach the 90% level of reductions required by using renewable energy technologies. Solar energy technologies have been the most successfully applied of all renewable to date largely because they are the only systems that can be incorporated easily into the urban fabric. In addition, the short fossil fuel horizons that are predicted (c. 40 years left for oil and 65 years for gas) will drive the markets for solar technologies. For these reasons, the cities of the future will be powered by solar energy, to a greater or lesser extent, depending on the city form and location. In recognition of the need to move rapidly towards a renewable energy future, a group of international cities, including Oxford, have started the Solar City Network. In this paper we outline the

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

    In recent years, a system has been proposed that utilizes river heat, air-heat, exhaust heat from a cooler, etc., in addition to natural energy for the heat pump. With the introduction of such system, the amount of energy used and that of CO2 exhaust will be greatly reduced, but annual expenses will be increased as it stands. In order to improve the cost efficiency of the system, a proposal has been made for the introduction of an economic policy such as the carbon tax and a low interest financing system. With these matters in the background, the subject study predicts the production of solar cells in the future and, on the basis of this production, determines the price, conversion efficiency and equipment energy of solar cells in the future. Using these values and taking into consideration the introduction of the carbon tax and the low interest financing system, the optimum area was determined for solar cells and heat concentrators in a future residential solar/air-heat energy system. The carbon tax, being imposed on all CO2 discharges, had a large effect. Moreover, as the tax increased, annual expenses decreased for the solar/air-heat system. 3 refs., 6 figs.

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

    Full Text Available The conservative family lifestyle in the Ottoman State affected the ways that houses were planned and decorated. Different decorative programs emerged with major differences in each period. New techniques and styles began to be seen in the 18th century thanks to the influence of the West. This article will focus on the decoration of Dedebayrak House in Ankara. Decoration in the architecture found within the boundaries of Ankara consist mostly of geometrical or floral decorations and various inscriptions. The Dedebayrak House not only has these kind of decorations, but also it has these decorations in its architectural descriptions, so it makes this house the only one to have survived in Ankara. Moreover, this building is especially important as the décor included work belonging to Nakkaş Mustafa. However, these decorative features do not remain today. The situation in Turkey is such that architecture is not conserved, which leads to many historically important buildings vanishing. Neither local authorities, nor the owner of these buildings look after these buildings properly, leading their specific historical features to be lost. This situation both damages the urban fabric and harms the historical heritage of the city. Therefore, decorative features in the building will be analysed both on their own and compared to other buildings in Ankara in order to create an overall picture.

    The term house doctor may be generalized to include persons skilled in the use of instruments and procedures necessary to identify, diagnose, and correct indoor air quality problems as well as energy, infiltration, and structural problems in houses. A radon house doctor would then be a specialist in radon house problems. Valuable experience in the skills necessary to be developed by radon house doctors has recently been gained in an extensive radon monitoring and mitigation program in upstate New York sponsored by Niagara Mohawk Power Corporation and the New York State Energy Research and Development Authority. These skills, to be described in detail in this paper, include: (i) the use of appropriate instruments, (ii) the evaluation of the symptoms of a radon-sick house, (iii) the diagnostic procedures required to characterize radon sources in houses, (iv) the prescription procedures needed to specify treatment of the problem, (v) the supervision of the implementation of the treatment program, (vi) the check-up procedures required to insure the house cured of radon problems. 31 references, 3 tables

    It is pointed out that in 1970 the total energy consumed in the U.S. was equal to the energy of sunlight received by only 0.15% of the land area of the continental U.S. The utilization of solar energy might, therefore, provide an approach for solving the energy crisis produced by the consumption of irreplaceable fossil fuels at a steadily increasing rate. Questions regarding the availability of solar energy are discussed along with the design of solar energy collectors and various approaches for heating houses and buildings by utilizing solar radiation. Other subjects considered are related to the heating of water partly or entirely with solar energy, the design of air conditioning systems based on the use of solar energy, electric power generation by a solar thermal and a photovoltaic approach, solar total energy systems, industrial and agricultural applications of solar energy, solar stills, the utilization of ocean thermal power, power systems based on the use of wind, and solar-energy power systems making use of geosynchronous power plants.

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

    This report describes the fiscal 1974 research result on solar cooling/heating and hot water supply systems for existing detached houses. The program for calculating heat collection rates was prepared by integrating peripheral conditions and every calculation step of heat collection rate, mean value, accumulated value and changes caused by disturbance. The cooling/heating load calculation program was also prepared for unsteady dynamic thermal analysis of houses. Another program was prepared for hot water supply load because of a large difference in life pattern. The profitability and energy conservation of 644 systems different in heat source, heat discharge, heat collection, heat storage, auxiliary heat source and equipment were evaluated by heat balance calculation program. Survey and study were also made on various heat engines such as heat pump, absorption refrigerator and Rankine cycle engine. Based on the survey result on existing technology for plane collectors, the optimum design method of collectors were established through various characteristic tests. Some kinds of suitable fusion latent heat type heat media were selected, and their operation stabilities were studied. (NEDO)

    2006-01-01

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

    This paper is the first to consider a large scale natural experiment to estimate the effect of taxes on house prices. We find that a 1 percentage-point increase in income tax rates lead to a drop in house prices of at most 2.2%. This corresponds to a tax capitalization for the average household...... capitalization from earlier studies. Furthermore, we find no effect of property taxes on house prices. We attribute this to the low levels of Danish municipal property tax rates compared to income tax rates....

    International Nuclear Information System (INIS)

    1993-01-01

    This report is based on a previous, related, one which was quantitative in character and relied on 500 telephone interviews with house-owners. The aim of this, following, report was to carry out a more deep-going, qualitative analysis focussed on persons who already own a solar heating system (purchased during 1992) or were/are considering having one installed. Aspects studied were the attitudes, behaviour and plans of these two groups with regard to solar heating systems. Some of the key questions asked concerned general attitudes to energy supply, advantages and disadvantages of using solar heating systems, related decision-making factors, installation problems, positive and negative expectations, evaluation of the information situation, suggestions related to information systems regarding themes etc., dissemination of information, sources of advice and information, economical considerations, satisfaction with the currently-owned system which would lead to the installation of another one in connection with the purchase of a new house. The results of this investigation directed at Danish house-owners are presented and discussed, and proposals for following activities within the marketing situation are given. It is concluded that the basic attitude in both groups strongly supports environmental protection, renewable energy sources and is influenced by considerations of prestige and independence. Constraint factors are confusion about environmental factors, insecurity in relation to the effect of established supplementary energy supply and suspicion with regard to the integrity of information received.

    Outlined herein is performance of the solar system, followed for a year, installed in a solar house (HARBEMAN HOUSE) built in 1996 in City of Sendai. The house is equipped, on the roof, with a 30.42m{sup 2} wide solar collector on the south and sky radiator on the north. They are connected to a heat-insulated tank (31m{sup 3}) installed underground, storing hot or cool water which carries energy for heating/air-conditioning and hot water. The solar system operates in a long-term hot or cool water storage mode. In the hot water storage mode, the solar collector is connected to the underground main tank, where pumped-up water heated by solar heat is stored to be supplied as hot water. Heat collected is low during the December-February period, and recovered in March. In the cool water storage mode, the radiator is connected to the underground main tank, where pumped-up water is cooled by radiation and stored to be supplied to a fan coil unit in each room for air-conditioning. The recorded lowest temperature of water in the tank is 5.1degC. No air-conditioning load is observed, on account of the unseasonal weather. 3 refs., 10 figs., 2 tabs.

The characteristics of households, of housing and their relation influence the housing situation in the city. Characteristic of housing refer mainly to quality of the dwellings, affordability and correspondence to the wishes of the inhabitants. The second important dimensions are households and their characteristics. In Europe and Slovenia increase in number of household can be observed, which in turn are becoming smaller. The housing policy has a role in establishing a balance between households and housing, i.e. ensuring that housing corresponds to the needs of individual households and to their number. For achieving this, knowledge and appropriate data are of vital importance. In the article we present the results of the Housing survey 2005. We observe housing conditions in a comparative perspective (Ljubljana in comparison to Maribor, Slovenia and selected European cities and according to three dimensions: housing fund, households and housing conditions.

    Hobbett, A. (Leicester Ecology Trust (United Kingdom))

    The Eco House is a former park keeper's lodge on the periphery of Leicester's largest public park. Taken over by Leicester Ecology Trust in 1990, the Eco House was a successor to the Trust's earlier low energy house. This has been a local authority decant house, retrofitted to show the potential for increased energy efficiency in older buildings. Many of the ideas from the earlier project were adopted by the new with a widening of its remit to include all matters of environmental concern connected with people's homes. So in addition to energy efficiency, other issues addressed include conservation of resources, wildlife, organic gardening, food production, water, environmental consumerism, recycling and health. Given that the use of energy is regarded by many environmentalists to be the single most important environmental issue today, and one which is easiest for households to address, it remains the project's dominant theme.

  9. Passive houses in Norway

    Energy Technology Data Exchange (ETDEWEB)

    Halse, Andreas

    2008-12-15

    The paper analyzes the introduction of passive houses in the Norwegian house market. Passive houses are houses with extremely low levels of energy consumption for heating, and have not yet been built in Norway, but have started to enter the market in Germany and some other countries. The construction sector is analyzed as a sectoral innovation system. The different elements of the innovation system are studied. This includes government agencies, producers, consumers, finance and education. The analysis shows that passive and low-energy houses are on the verge of market breakthrough. This can partly be explained by economic calculations, and partly by processes of learning and change in the institutional set-up of the sector. The construction sector is a sector characterized by low innovative intensity and little interaction between different agents. Those working to promote passive houses have to some extent managed to cope with these challenges. This has happened by breaking away from the traditional focus of Norwegian energy efficiency policies on technology and the economically rational agents, by instead focusing on knowledge and institutional change at the level of the producers.

    The connection between housing and health is well established. Physical, chemical, and biological aspects of the child's home, such as cleanliness, moisture, pests, noise, accessibility, injury risks, and other forms of housing environmental quality, all have the potential to influence multiple aspects of the health and development of children. Basic sanitation, reduced household crowding, other improvements in housing and expanded, and improved housing regulations have led to advances in children's health. For example, lead poisoning prevention policies have profoundly reduced childhood lead exposure in the United States. This and many other successes highlight the health benefits for families, particularly children, by targeting interventions that reduce or eliminate harmful exposures in the home. Additionally, parental mental health problems, food insecurity, domestic violence, and the presence of guns in children's homes all are largely experienced by children in their homes, which are not as yet considered part of the Healthy Homes agenda. There is a large movement and now a regulatory structure being put in place for healthy housing, which is becoming closely wedded with environmental health, public health, and the practice of pediatrics. The importance of homes in children's lives, history of healthy homes, asthma, and exposures to lead, carbon monoxide, secondhand/thirdhand smoke, radon, allergy triggers is discussed, as well as how changes in ambient temperature, increased humidity, poor ventilation, water quality, infectious diseases, housing structure, guns, electronic media, family structure, and domestic violence all affect children's health.

    The application of bioclimatic principles is a critical factor in reducing energy consumption and CO2 emissions. This poster develops a sequence of experiments and building working models in order to form students of secondary school and make progress towards real applications of new energy technologies. The activity has been carried out by 14 and 15-year-old students using a Power House building kit. Scientific method and Information and Communication Technologies (ICT) were used as an effective system of acquiring new knowledge. Students were asked to form cooperative groups. Firstly, each group had to choose the best location and orientation in the imaginary Dragon Island for the construction of the house. The house consisted of eight Styrofoam parts and one transparent plastic part. The Styrofoam parts formed the house structure (floor, walls and roof) with two interior chambers and the attached greenhouse. Once the house was assembled in a few steps, it was ready for the students to start adding more components. Students then conducted several experiments related to the heat and light energy of the Sun and the energy of the wind. Some of the experiments and building projects realized were: how to capture the Sun to heat the house by passive solar heating, how to collect the Sun's rays to heat water using a Sun Collector and how to extract electricity current from Sun Power station and from wind power plant. For most of the assays it was necessary to record the temperature and students used for that purpose a temperature sensor that comes with Multilog Pro, a portable, graphic data collection and analysis system. Groups of students were really engaged in the project and each of them ran a different test with the house. Finally they proved if their initial hypothesis was correct and they had to expose the results to the rest of the class members. Students demonstrated how we can transform and use renewable forms of energy. With the experiments students

    This study explores factors contributing to delays and relocations during the implementation of the Housing First model in Toronto, Ontario. While interruptions in housing tenure are expected en route to recovery and housing stability, consumer and service provider views on finding and keeping housing remain largely unknown. In-person interviews and focus groups were conducted with 48 study participants, including 23 case managers or housing workers and 25 consumers. The following three factors contributed to housing delays and transfers: (1) the effectiveness of communication and collaboration among consumers and service providers, (2) consumer-driven preferences and ambivalence, and (3) provider prioritization of consumer choice over immediate housing access. Two strategies--targeted communications and consumer engagement in housing searches--supported the housing process. Several factors affect the timing and stability of housing. Communication between and among providers and consumers, and a shared understanding of consumer choice, can further support choice and recovery.

    Solar storms begin with an explosion, or solar flare, on the surface of the sun. The X-rays and extreme ultraviolet radiation from the flare reach the Earths orbit minutes later-travelling at light speed. The ionization of upper layers of our atmosphere could cause radio blackouts and satellite navigation errors (GPS). Soon after, a wave of energetic particles, electrons and protons accelerated by the explosion crosses the orbit of the Earth, and can cause real and significant damage. (Author)

    Everybody can learn to build energy-efficient. It needs theoretical and practical experience. 1997 we built the first freestanding Passive House in Europe, the Passive House Oehler. There had been a lot of questions, starting with the insecurity, whether the calculation program of the Passive House Institute, the PHPP, is working properly in our case. Nobody knew at that time because nobody tried it out before. It took us a lot of time to find out and every detail of the construction hat to be invented to meet the very high demand of thermal quality. All the following houses needed less time and had fewer open questions, adding one piece of experience with every building. 2002 we realised the biggest Passive House, the office building Energon Ulm with 420 working spaces. In the meantime we have learned a lot like how to produce prefabricated timber elements for the facades, providing good insulation, air tightness and avoiding serious thermal bridges. We have proofed, that any kind of building type can be a Passive House. And with increasing experience the freedom of design and construction is growing. Even the economical efficiency increased. The Energon Ulm is providing a much better indoor climate than any other office building and was build 10 % cheaper than an average German office building. At present the Passive House Standard is the most efficient solution for the user to live in the desired comfort zone between 20 C and 25 C. This zone of individual feeling-well can be described with the term ''operative temperature''. This term is defined by factors like air temperature, radiation temperature of warm and cold surfaces, air speed and humidity. The result of all these factors has to be within 18 C to 25 C without accepting one of the factors getting extreme.

    2015-01-01

    Highlights: • There is evidence for significant intraday variation of energy use. • The sensitivity of energy use to weather variation falls via efficiency features. • The sensitivity of energy use to weather depends on the specific time of day/night. • High frequency data helps to accurately model the energy use-weather relationship. - Abstract: This paper studies the impact of weather variation on energy use by using 5-minutes interval weather–energy data obtained from two residential houses: house 1 is a conventional house with advanced efficiency features and house 2 is a net-zero solar house with relatively more advanced efficiency features. Our result suggests that energy consumption in house 2 is not as sensitive to changes in weather variables as the conventional house. On average, we find that a one unit increase in heating and cooling degree minutes increases energy use by about 9% and 5% respectively for house 1 and 5% and 4% respectively for house 2. In addition, our findings suggest that non-temperature variables such as solar radiation and humidity affect energy use where the sensitivity rates for house 2 are consistently lower than that of house 1. Furthermore our result suggests that the sensitivity of energy use to weather depends on the season and specific time of the day/night

    For all considerations on energy, information on energy-quantity and energy-value is necessary. Such information is presented for Germany as an example for an industrialized country. The application of solar heat for an Institute building is presented for a pilot project at the University Stuttgart. With unglazed solar collectors, a flooded pebble-bed store and a heat pump, about 60% of the Institute's heat demand can be supplied by solar energy. With the experience gained from this project, large district heating systems are designed for two different locations in Germany under differing conditions. For solar assisted house heating and domestic hot water, heat costs are obtained which are about twice the present heat cost in Germany. If solar energy assists domestic hot water production and house heating, costs can be achieved which are below present conventional heat cost. In addition, it will also reduce air pollution.

    The following technologies were developed for the purpose of putting into practice an innovative system that performs cooling/heating and hot-water supply for an existing private house economically by solar energy: (1) development of equipment constituting solar cooling/heating and hot-water supply system, and (2) development of a system which uses such equipment and which is inexpensive and safe as well as easy for inspection and maintenance. The results of the research were as follows. A latent heat type heat storage tank was developed in a small low-loss type in which ammonium alum was selected for a high temperature heat storage tank and in which NaCH{sub 3}COO(center dot)3H{sub 2}O were selected for a combination latent heat/cold water heat storage tank. A refrigerator was developed driven by a small Rankine cycle engine of a result coefficient of 0.47. A flat plate type heat collecting device was developed in a type having a BrNi selective absorbing film and materials of copper tube, aluminum plate and double glass. A vacuum heat collecting device was developed in a high efficient type with the outside dimension of {phi} (diameter) 70 x 1,270 mm, selective absorbing film BrNi, and a degree of vacuum of 10{sup -3}Torr. A heat receiving/releasing storm shutter was developed in a type using a latent heat storing material of paraffin wax. A heat absorbing/insulating outside wall panel was developed using FRP and aluminum as the materials. The system analysis also achieved success. (NEDO)

    Full Text Available For the storage tank of a solar system for domestic hot water production was analyzed the insulation thickness and material influence. To this end, it was considered a private house, occupied by 3 persons, located in zone I of thermal radiation, for which has been simulated the domestic hot water production process. The tank outlet hot water temperature was considered of 45°C. For simulation purposes, as insulation materials for the storage tank were taking into account glass wool and polyurethane with various thicknesses. Finally, was carried out the comparative analysis of two types of tanks, in terms of the insulation thickness influence on the solar fraction, annual solar contribution and solar annual productivity. It resulted that polyurethane is the most advantageous from all points of view.

  6. Energy conservation for houses and its calculation methods

    Energy Technology Data Exchange (ETDEWEB)

    Lee, S H

    1981-04-01

    The concept of energy conservation of houses has been developed and began to be applied widely since the first oil crisis. Now we can say definitely that insulating a house is the most effective way of saving energy, and the renewable energy sources are useful only when the demand for space heating and hot water is minimized by insulating. If a house is well insulated, it will need a much smaller, simpler and cheaper heating system. So it will be less efficient to put a solar collector and wind generator on a poorly insulated house. Architects and engineers should have a certain level of practical knowledge of insulation for house to persuade customers using insulating materials and structure. Moreover, it is very essential to amend the existing building codes in order to facilitate this basic necessity. For instance, the Building Regulations of Denmark requires a U-value of 0.4 W/m/sup 2/ degC for heavy weight external wall. If the cavity wall has outer and inner leaf of just normal brick with internal finish of 20 mm cement mortar, which is a typical wall construction for houses in Korea, the thickness of insulation materials to the cavity can be calculated in order to fullfil the U-value of 0.4 W/m/sup 2/ degC in addition to the cavity of the external heavy wall: expanded polyurethane 58 mm, urea formaldehyde foam 67 mm, expanded polystyrene 78 mm, mineral wool 94 mm. The economic feasibility of solar heating system has been calculated. By applying 25% of the year inflation ratio for fuel cost, the result turns out economically comparable with solar heating systems.

    Full Text Available In some streets of Belgrade we can still find old houses, which hold an ancient dream of dignity, comfort and beauty. They probably live their last days, staring somewhere in the distance - into foggy spaces of their forgetfulness. They stand in fragile rows, increasingly dilapidated disappearing one by one, pretty and sad in their loneliness. They fade attacked by winds, by sunshine, by rains, sorrowed by coldness of their empty rooms. We have no right to let them disappear without any remembrance, to allow them to vanish from of our lives, because - if that happens - that will make poorer both our legacy and us for the future. Thus, we must find ways to hold these old houses, to read and understand their messages, to keep the prints of their spirit and shapes. How to achieve that? If it is true that the beauty of the landscape is hidden in the eyes, which look at it, then drawing is certainly one of the modes to record the wonderful secret of these pretty old houses, silently disappearing from the urban life.

    Full Text Available Frank Capra expressed his gratitude to the immigrant dream come true by creating a brilliant cinematic myth about the American political system, presenting it as an 'inherently good' when in the hands of honest and good people. His 'morality fairytales', 'fantasies of good will' imbued with belief in restoration of old-new principles, offer complex reflections on an idealised Americanism of the 1930s which have become the foundation of representations of the American political system. The Capraesque narrative - 'a blend of optimism, humor, patriotism, and, to those who really understand his work, (and darkness, despair, and the need to fight for things you care about...' (Bassinger 1982: 48 - as a combination of all-American values, ordinary people and historical figures, a democracy myth - has been extended by an endless network of intertextual echoes in film and TV production.

  14. Radionuclides in house dust

    Energy Technology Data Exchange (ETDEWEB)

    1985-04-01

    Discharges of radionuclides from the British Nuclear Fuel plc (BNFL) reprocessing plant at Sellafield in Cumbria have led to elevated concentrations radionuclides in the local environment. The major routes of exposure of the public are kept under review by the appropriate authorising Government departments and monitoring is carried out both by the departments and by BNFL itself. Recently, there has been increasing public concern about general environmental contamination resulting from the discharges and, in particular, about possible exposure of members of the public by routes not previously investigated in detail. One such postulated route of exposure that has attracted the interest of the public, the press and Parliament arises from the presence of radionuclides within houses. In view of this obvious and widespread concern, the Board has undertaken a sampling programme in a few communities in Cumbria to assess the radiological significance of this source of exposure. From the results of our study, we conclude that, although radionuclides originating rom the BNFL site can be detected in house dust, this source of contamination is a negligible route of exposure for members of the public in West Cumbria. This report presents the results of the Board's study of house dust in twenty homes in Cumbria during the spring and summer of 1984. A more intensive investigation is being carried out by Imperial College. (author)

    This paper analyzes the cost-effectiveness in the mitigation of green house gases from solar, eolic and nuclear energy sources, concluding that nuclear is, not doubt, the mos efficient. On the other hand, nuclear is the unique source that can be installed without limit in magnitude and in the proximity of the demand, and is for all these reasons that several environmental referents in the world have changed their perception on this source and defend it as the unique actual alternative to fight against the emission of green house gases.

    Kari-Koskinen, O; Karvonen, P

    1976-01-01

    With the present trend away from the designing of individual buildings and towards the systematic planning of whole residential communities, it should be possible to take mental health requirements into account at the planning stage. At present, sociologists are all too seldom consulted on matters of residential planning. When discussing the relationship between housing and mental health one cannot restrict oneself only to the external aspects of the house, but rather one must also consider the opportunities available for the members of the family to satisfy their own needs, both within the home and in its immediate surroundings. Factors which may affect residential requirements include geographical location, type and standard of dwelling and time and continuity of occupation. A move between two districts or groups representing different housing norms and values may lead to withdrawal symptoms in the individual. This may arise equally well from the remoteness of the country districts as from the conflicting pressures brought on by the abundance of contacts available in the large towns. Town life tends to heighten susceptibility to neuroses and personality conflicts. The character of a residential area may affect the mental health of its occupants. Faris & Dunham (4), in studying the incidence of various types of mental illness with an urban population, observed that schizophrenia was most common among people who were in some way isolated from social involvement. The striving for spaciousness in residential areas and the creation of a "summer city" or "garden city" image or a "family-centred way of life" may lead to unexpected problems and have a variety of social consequences. Mental health difficulties have been noted, for example, among housewives in "dormitory" towns or suburbs (11). The institutions required by a community may be grouped into four categories, representing the basic needs of its members. These are (1) economic institutions, (2) social and

    DOE awarded funds to support a demonstration project to illustrate how access to solar power and green roof systems could improve building performance and long-term outcomes for the building owner and multiple nonprofit tenants housed in the building. Since being placed in service the solar PV system has saved approximately $1,000 per month in energy costs. The green roof has added to this benefit by naturally cooling the building and has helped reduce local road flooding by retaining storm water. These elements have improved the quality of life in the low-income community in which the building is located by allowing social service organizations to focus more of their resources on programs and job creation.

    The design, testing and evaluation of two prototype solar holes are discussed. The first prototype is a greenhouse-residence designed with 6-in. wall cavities (to increase insulation thickness), a 381 sq. ft. solar collector used primarily for space heating, and a greenhouse that was utilized as a solar collector for growing vegetables. The house does feature a domestic hot water preheating system and an electrical resistance back-up heating system. The second prototype is an earth-insulated house designed primarily to study the physical features of the house in relation to the soil around it and the thermal interaction between the soil and the house environment. This house features a high temperature air collector that is used for domestic water heating. A special effort was made to have adequate daylight in the solar-earth house. A special study was conducted on the geometric configuration of the rock storage and the methods of admitting air to the rock storage.

    By using the 2002 case of fraud in the Danish municipality Farum by then mayor Peter Brixtofte as an exogenous shock to public debt of 1 billion DKK, I estimate the effect of public debt on house prices. I find that the average home ownership lost about 570,000 DKK or as much as 29% of the average...... house price in the municipality. Furthermore, I document that the aggregate house price loss of 2.1 billion DKK greatly exceeds the increase in public debt of 1 billion DKK. I find that the drop in house prices is sustained 1 year, indicating that the housing market initially overreacts...

    . Originality/value - Many different Solar Combisystem designs have been commercialized over the years. In the IEA-SHC Task 26, twenty one solar combisystems have been described and analyzed. Maybe the mantle tank approach also for solar combisystems can be used with advantage? This might be possible...... if the solar heating system is based on a so called bikini tank. Therefore the new developed solar combisystems based on bikini tanks is compared to the tank-in-tank solar combisystems to elucidate which one is suitable for three different houses with low energy heating demand, medium and high heating demand.......Purpose - Low flow bikini solar combisystems and high flow tank-in-tank solar combisystems have been studied theoretically. The aim of the paper is to study which of these two solar combisystem designs is suitable for different houses. The thermal performance of solar combisystems based on the two...

  6. Is Housing a Health Insult?

    Baker, Emma; Beer, Andrew; Lester, Laurence; Pevalin, David; Whitehead, Christine; Bentley, Rebecca

    2017-05-26

    In seeking to understand the relationship between housing and health, research attention is often focussed on separate components of people's whole housing 'bundles'. We propose in this paper that such conceptual and methodological abstraction of elements of the housing and health relationship limits our ability to understand the scale of the accumulated effect of housing on health and thereby contributes to the under-recognition of adequate housing as a social policy tool and powerful health intervention. In this paper, we propose and describe an index to capture the means by which housing bundles influence health. We conceptualise the index as reflecting accumulated housing 'insults to health'-an Index of Housing Insults (IHI). We apply the index to a sample of 1000 low-income households in Australia. The analysis shows a graded association between housing insults and health on all outcome measures. Further, after controlling for possible confounders, the IHI is shown to provide additional predictive power to the explanation of levels of mental health, general health and clinical depression beyond more traditional proxy measures. Overall, this paper reinforces the need to look not just at separate housing components but to embrace a broader understanding of the relationship between housing and health.

    The Solar Decathlon competition challenges students across the country to design and build a net-zero, market ready solar powered home. The bi-annual competition consists of ten contests that seek to balance the home on a scale of innovation. The ten contests were selected by to organizers to address all aspects of housing, including architecture, market appeal, engineering, communication, affordability, comfort, appliances, home life, commuting, and energy balance. Along with the criteria associated with the contests, the competition includes several design constraints that mirror those found in practical housing applications: including (but certainly not limited to) lot lines, building height, and ADA accessibility. The Solar Decathlon 2015 was held at the Orange Country Great Park in Irvine, CA. The 2015 competition was Clemson University’s first entry into the Solar Decathlon and was a notable milestone in the continued development of a home, called Indigo Pine. From the beginning, the team reconsidered the notion of sustainability as related to both the design of a home and the competition itself. The designing and building process for the home reflects a process which seamlessly moves between thinking and making to develop a comprehensive design with a method and innovations that challenge the conventions of residential construction. This report is a summary of the activities of the Clemson University team during the two-year duration of the project leading to the participation in the 2015 Solar Decathlon competition in Irvine California.

    Solar power is growing much faster than most policymakers and analysts realise. As costs come down and feed-in tariffs go up across Europe, a number of countries have started in pursuit of market leader Germany. But in Germany criticism is growing of the multi-billion-euro support schemes that keep the solar industry booming. In this section of the magazine several articles are dedicated to developments in solar energy in Europe. The first article is an overview story on the strong growing global market for solar cells, mainly thanks to subsidy schemes. The second article is on the position of foreign companies in the solar market in Italy. Article number three is dedicated to the conditions for solar technology companies to establish themselves in the German state of Saxony. Also the fifth article deals with the development of solar cells in Saxony: scientists, plant manufacturers and module producers in Saxony are working on new technologies that can be used to produce solar electricity cost-effectively. The goal is to bring the price down to match that of conventionally generated electricity within the next few years. The sixth article deals with the the solar power market in Belgium, which may be overheated or 'oversubsidized'. Article seven is on France, which used to be a pioneer in solar technology, but now produces only a fraction of the solar output of market leader Germany. However, new attractive feed-in-tariffs are changing the solar landscape drastically

  9. Environmental Health Disparities in Housing

    Science.gov (United States)

    2011-01-01

    The physical infrastructure and housing make human interaction possible and provide shelter. How well that infrastructure performs and which groups it serves have important implications for social equity and health. Populations in inadequate housing are more likely to have environmental diseases and injuries. Substantial disparities in housing have remained largely unchanged. Approximately 2.6 million (7.5%) non-Hispanic Blacks and 5.9 million Whites (2.8%) live in substandard housing. Segregation, lack of housing mobility, and homelessness are all associated with adverse health outcomes. Yet the experience with childhood lead poisoning in the United States has shown that housing-related disparities can be reduced. Effective interventions should be implemented to reduce environmental health disparities related to housing. PMID:21551378

    The article discusses reasons why fossil-fuelled water heating systems are included in new houses but solar systems are not. The technology and market potential for evacuated tube systems and integral collector storage systems (ICSS) are explained. The challenge for the designers of ICSSWH has been how to reduce heat loss without compromising solar energy collection. A new concept for enhanced energy storage is described in detail and input/output data are given for two versions of ICSSWH units. A table compares the costs of ICSSWH in houses compared with other (i.e. fossil fuel) water heating systems

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

    Solar sailing is a topic of growing technical and popular interest. Solar sail propulsion will make space exploration more affordable and offer access to destinations within (and beyond) the solar system that are currently beyond our technical reach. The lecture will describe solar sails, how they work, and what they will be used for in the exploration of space. It will include a discussion of current plans for solar sails and how advanced technology, such as nanotechnology, might enhance their performance. Much has been accomplished recently to make solar sail technology very close to becoming an engineering reality and it will soon be used by the world s space agencies in the exploration of the solar system and beyond. The first part of the lecture will summarize state-of-the-art space propulsion systems and technologies. Though these other technologies are the key to any deep space exploration by humans, robots, or both, solar-sail propulsion will make space exploration more affordable and offer access to distant and difficult destinations. The second part of the lecture will describe the fundamentals of space solar sail propulsion and will describe the near-, mid- and far-term missions that might use solar sails as a propulsion system. The third part of the lecture will describe solar sail technology and the construction of current and future sailcraft, including the work of both government and private space organizations.

    1996-01-01

    The objective of this study was to clarify the fluctuation of solar radiation for long and short periods, which is very crucial for plant growth. Data obtained from a meteorological observatory were used to investigate solar radiation and sunshine duration for a long period. For a short period, observation of global solar radiation and sky solar radiation were conducted in a glass house and at an open field. (1) Yearly average percentage of solar radiation at Kagawa from 1973 to 1994 was 44.3%, and its coefficient of variation was 3.9%. The percentage of possible sunshine and the coefficient were larger than those of solar radiation, 47.3% and 56% respectively. (2) Percentage of possible solar radiation and percentage of possible sunshine showed seasonal variation. Those coefficients of variation both increased exponentially with cloud amount. (3) Variations of global solar radiation and direct solar radiation were more remarkable in the glass house than those in the open field, while variations of sky solar radiation were small in the house and at the open field. (4) The fluctuation of solar radiation observed every 5 minutes was presented as the difference of radiation, present value minus the preceding value. The difference was positive in the morning, negative in the afternoon at the open field. In the house both positive and negative values were obtained the whole day. (5) Diurnal variation of ratio of direct solar radiation to sky solar radiation showed a parabolic effect, whereas it had irregular and large fluctuations at the open field

    New England Solar Homes is an emerging solar home company offering custom architectural services as well as a line of standard house plans to clients across the country. Their standard builder's sets can be used off the shelf or altered to fit varied climates and siting conditions. The Solar Farmhouse concept house was introduced at the Eco-Expo in 1995 as a demonstration of how an American country classic could be adapted and outfitted to be an advanced energy efficient passive and active solar home that would have immediate popular appeal. The inspiration for this design was based on the wisdom and surprisingly skillful design abilities of the American farmer, circa 1800s and onward. The Solonial became the first built demonstration home in Lexington, MA incorporating the energy performance standards of the Solar Farmhouse. Two other homes will start construction this spring--Solar Farmhouse II, and DC Solar I, in Pennsylvania and Maryland, respectively. The Beyond in the title refers to their interest in participating in the New Urbanism movement which is gaining momentum around the country in equal proportion to the loss of habitat from urban sprawl with its impact on quality of life indicators. Solar designers and developers could find some emerging opportunities with this highly unusual American attempt at regional planning.

  8. Strategies for Living in Houses

    Directory of Open Access Journals (Sweden)

    Colin Ripley

    2017-12-01

    Full Text Available The problem of queer housing can never go away because it is a central component of queerness. Queer housing is a contradiction in terms: not even a queer architect can design a queer house. But where does this leave us, as queer people living in a straight hegemony? Where does it leave us as humans with bodies, craving shelter and safety and a place to live that is in accordance with our experience of self and of living in the world? In this article the author proposes eight architectural strategies for re-occupying the Levittown Cape Cod house from 1947 for queer bodies, minds and hearts. These strategies offer modes by which the key programmatic formal and material components of the Cape Cod House can be attacked, made invalid, or détourned for queer uses, to make of the Cape Cod House a site for our pain, our longing, our anger.

  11. The Envirohome: Sustainable housing guidebook and reference manual

    Energy Technology Data Exchange (ETDEWEB)

    1994-01-01

    The EnviroHome was designed as part of Nova Scotia's Advanced House Project, a response to a national competition to construct the most energy-efficient and environmentally responsible homes in Canada. The house was designed to have a total purchased energy consumption 50% less than Canada's current energy efficient building standard, the R-2000 program. A guidebook is presented which describes the novel features of a three-bedroom, 2,200 ft[sup 2] Envirohome built according to the Advanced Houses Program design requirements. Features include a high-efficiency oil-fired space heating system coupled with a solar domestic hot water system; high levels of blown cellulose insulation and highly airtight construction; an 84% efficient heat recovery ventilator; passive solar design; high-performance low-emissivity windows; a recycling center in the kitchen; energy efficient appliances and lighting; integration of the performance of heating, hot water, solar collection, and ventilation systems by a direct digital control automation center; a low-pollution contraflow fireplace; and water-saving plumbing fixtures. During construction, 62% of the construction waste was recycled and 6% was reused. Over 20,000 lb of recycled material was used in building the Envirohome, including fly ash in the concrete for the foundations, newsprint in the insulation and drywall, and sawdust in the hardboard siding. Interior finishes and materials were chosen to avoid harmful emissions, and exterior finishes are virtually maintenance-free. 5 refs., 58 figs., 2 tabs.

    This study examines the behavior of Swiss house prices to immigration flows for 85 districts from 2001 to 2006. The results show that the nexus between immigration and house prices holds even in an environment of low house price inflation, nationwide rent control, and modest immigration flows. An immigration inflow equal to 1% of an area's population is coincident with an increase in prices for single-family homes of about 2.7%: a result consistent with previous studies. The overall immigrati...

    Integral energy concepts for housing estates require an early cooperation between architects, planners, and specialist engineers on the basis of a holistic planning approach. This is how future-oriented, sustainable concepts evolve which do justice to the multifarious requirements on the integral energy system of a housing estate. The present paper elucidates different approaches to optimising the energy efficiency of buildings such as the implementation of low-energy house concepts, building site and architectural planning, and detailed planning of heat insulation concepts, ventilation and air tightness concepts, and adapted heating systems. The solarisation of development plans has an influence on the arrangement of buildings, which are now planned to give the greatest possible passive and active solar energy gains. The authors also describe solar-assisted district heating systems for housing estates. [Deutsch] Integrale Energiekonzepte fuer Wohnsiedlungen erfordern die fruehe Zusammenarbeit von Architekten, Planern und Fachingenieuren im Rahmen einer ganzheitlichen Planung. So entstehen zukunftsweisende und tragfaehige Konzepte, die den vielschichtigen Anforderungen des Gesamtenergiesystems ``Wohnsiedlung`` gerecht werden. Im Folgenden wird die energetische Optimierung von Gebaeuden wie die Umsetzung von Niedrigenergiehaus-Konzepten, Standort und Gebaeudeplanung sowie Detailplanung in Bezug auf das Waermedaemmkonzept, Lueftungs-/Dichtheitskonzept und auf angepasste Waermeversorgungssysteme erl autert. Die Solarisierung von Bebauungsplaenen beeinflusste Anordnung der Gebaeude hinsichtlich der Nutzung passivsolarer Gewinne sowie des Einsatzes von Systemen der aktiven Solarenergienutzung.

    2016-01-01

    Full Text Available Housing has always been a significant aspiration of family expression and distinctly priciest investment by household. It plays a momentous role in the country’s economy and so central to the societal well-being that is emplaced in the United Nation Universal declaration of Human rights. Yet in developed and developing world alike, cities struggle to provide decent housing for lower and middle income population. The provision of affordable housing is a major policy concern around the world with Malaysia being no exception; rising income hardly keep pace with price hike of housing unit and housing interventions has majorly concentrated on demand side leading to a non-responsive supply sector. Therefore, this paper highlights affordable housing issues pertaining Malaysia. It formulates Malaysian Map of affordability and conducts an evaluation of global housing schemes to better identify policy priorities for Malaysia. It’s significant to harmonize supply and demand side factors in the housing market to ensure that housing supply fits the needs of citizens based on the location, price and target group. In case of Malaysia supply oriented initiative are of urgency in short and medium run. This must be supported by long term demand side schemes in parallel. Convergence of these two factors is essential for a balanced equilibrium and obtaining affordability.

  19. Comprehensive energy and economic analyses on a zero energy house versus a conventional house

    Energy Technology Data Exchange (ETDEWEB)

    Zhu, L. [School of Architecture, Tianjin University, Tianjin, 300072 (China); Hurt, R.; Correa, D.; Boehm, R. [Center for Energy Research, University of Nevada, Las Vegas, NV 89154 (United States)

    2009-09-15

    A zero energy house (ZEH) was built side by side with a baseline house in suburban Las Vegas. Actual energy performance measurements were carried out on the incorporated energy saving features and solar applications. The data show that a radiant barrier and a water-cooled air conditioner are major contributors to the energy savings, while an insulated floor slab and thermal mass walls are not effective for energy-conservation during cooling periods. Photovoltaic roof tiles produce enough green power to cover the use in the ZEH, and the solar water heater can reach a peak efficiency of 80%. The energy saving contribution of each incorporated component was obtained using Energy10 and eQUEST3.6 models, and then these codes were used for economic application evaluation. The two analysis codes yield similar results that compare well with the actual building performance data. Four items are clearly economically valuable for these applications: high performance windows, compact fluorescent lights, highly-insulated roofs and air conditioners with water-cooled condensers. PV tiles show a good financial return when rebates are considered. The Integrated Collector Storage (ICS) unit has a high efficiency but with a little higher thermal price. Thermal mass walls are too costly to have wide market appeal. (author)

    Fry, F A; Green, N; Hammond, D J

    1985-01-01

    Discharges of radionuclides from the British Nuclear Fuel plc (BNFL) reprocessing plant at Sellafield in Cumbria have led to elevated concentrations radionuclides in the local environment. The major routes of exposure of the public are kept under review by the appropriate Government departments and monitoring is carried out both by the departments and by BNFL itself. Recently, there has been increasing public concern about general environmental contamination resulting from the discharges and, in particular, about possible exposure of members of the public by routes not previously investigated in detail. One such postulated route of exposure that has attracted the interest of the public, the press and Parliament arises from the presence of radionuclides within houses. In view of this obvious and widespread concern, the Board has undertaken a sampling programme in a few communities in Cumbria to assess the radiological significance of this source of exposure. From the results of our study, we conclude that, alt...

    Full Text Available Discourses on woman/space relations boomed in the 90s. The fundamental reason was to give support to the Feminist Movement. This trend which has had feeble effect on architectural design remained controversial. The comprehensive research expounded in this article which was based on an open-ended questionnaire that targeted at determining the gender roles at home, applied to female subjects who simulated the national demographics, clearly demonstrated that the home experience of an average Turkish woman basically consists of kitchens; the female who runs the house does not really have a place for herself at home. However she does not perceive her restrained, secondary role an issue worthy of struggling to change and she grants spaces for recreation and study to the male. The well-established civil laws conducive for equality has not changed this disturbing situation and do not seem to do so in the near future.

    It is often believed that reduction in energy use automatically leads to the total reduction of the carbon footprint and other emissions. To achieve better energy efficiency more raw materials may be needed not only for insulation and better windows but also for heating systems like ground source heat and solar panels. The use of advanced building systems increase the use of electricity and in winter where electricity production is already inadequate the additional stand-by power plants must be taken in use. These are not as effective as CHP plants for heat production. Moreover also the passive house structures can be produced in dozens ways and from many different materials which all have different service life, different need for maintenance and also different effect on the overall carbon footprint. Finally as the nursery is the overall concept, besides the building structures outdoor playgrounds and specific operations requiring day care trips, personnel commuting and waste treatment must be taken into account.

    The Housing Program Measure (HPM) was designed to document critical elements of a range of housing program types and associated services. Qualitative methods, including literature review and open-ended interviews, were used to determine pertinent HPM domains and to develop the pool of items. The measure was pre-tested, and reliability and validity analyses were applied to revise and strengthen the measure. The resulting measure furthers homelessness research by providing a tool that can be used to define housing and housing services interventions across diverse projects and disciplines, to facilitate program management by matching housing resources to the needs of homeless individuals, and to support model development by measuring progress to goals.

    Accurate tests of the theory of stellar structure and evolution are available from the Sun's observations. The solar constraints are reviewed, with a special attention to the recent progress in observing global solar oscillations. Each constraint is sensitive to a given region of the Sun. The present solar models (standard, low Z, mixed) are discussed with respect to neutrino flux, low and high degree five-minute oscillations and low degree internal gravity modes. It appears that actually there do not exist solar models able to fully account for all the observed quantities. (Auth.)

    The use of solar energy at large scale is necessary to support the energy savings and a more efficient energy use, like besides the quality of the ambient and the quality of the available energy sources. The solar heating systems with seasonal storage can be combined with heat from refuse incineration plants and other renewable heat sources. These systems combined with district heating are an example of the sustainable energy planning and the reduction of the environmental stress. Strategies for sustainability in the settlements can be defined by and energy model to planning that individuates development and economic and financial supports to. The aim of the work concerns the development of a small sun city with no use of fossil fuels. The new low energy solar town is an idealised urban an energy system. The studied settlement regards one thousand new low-energy houses supplied by a district heating with a central solar heating system with seasonal heat storage. The heating and ventilation demand in the studied low energy buildings are less than 40 kWh/m{sup 2}/year, the electricity demand is less than 2000 kWh per house year. The result of the work is an useful tool to the energy planning of the urban areas and it is also a necessary support to the political and energetic decisions. (EG) 58 refs.

    2001-07-01

    This paper discussed the construction and design of 3 affordable passive solar homes located in high latitudes: (1) the Kindred house located in a wooded subdivision in Hancock, Michigan; (2) the Autio house located in Laurium, Michigan; and the Mikkola house located in South Range, Michigan. The award-winning houses were part of the United States federal government's Energy Star program. The houses were constructed with common building materials in order to introduce the general public to the principles of energy-conscious passive solar design strategies and sustainable construction technologies. Super-insulation was used to retain solar heat gain in the houses. Air infiltration was minimized through the use of an airtight drywall sealing technique. Large windows were a prominent feature of the southern facades of the houses. The windows used fixed and casement low-e argon-filled insulated glazing. Average bills for the Kindred home are US$960 per year. It was concluded that passive solar design and construction strategies are now being used more often in the area as a result of the positive media coverage that the homes has received. 5 refs.

    The first conference organized by the newly established Canadian Solar Buildings Research Network (SBRN) was held in conjunction with the thirty-first annual conference of the Solar Energy Society of Canada Inc (SESCI). The conference was attended by top researchers from 10 Canadian Universities to promote innovative research and development in solar energy applications and to advance the awareness of solar energy in Canada. It featured special events such as trade shows, photovoltaic workshops, a course in ESP-r simulation, tours of solar houses and other events focused on the economic, environmental and socio-economic benefits of solar technology, including the potential to reduce greenhouse gas emissions. SBRN was founded on the premise that university researchers should focus on solar energy applications for buildings. Several presentations proposed action plans to accelerate the implementation of solar energy through the use of innovative building technologies and sustainable energy policies. Other major issues of interest were also discussed, including the development of the net-zero energy solar home and grid-connection issues. The sessions of the conference were entitled: solar thermal systems; solar electricity; building integrated photovoltaic systems; design issues and tools; integrating PV and solar thermal in buildings; daylighting and solar radiation modeling; fenestration and shading; PV manufacturing and solar electricity resources. The proceedings featured 41 refereed papers and 13 poster presentations, all of which have been catalogued separately for inclusion in this database. refs., tabs., figs

    constitutes a true improvement of daylighting level rather than a fashion. Especially for new activities such as reading and using modern kitchen equipment, the lighting in traditional houses is not adequate. Only the courtyard receives enough daylight, but it is not uniformly distributed and the activities are therefore located according to their visual demands. The daylighting in modern houses, on the other hand, allows a larger number of activities to take place in different spaces. Most studies on design of passive buildings recommend the location of windows on the south facade because of the ease of passive solar control during summer and optimum solar gain during winter. However, in the urban reality, a house could be oriented to the east, west or north, depending on the constraints of the site. Recommendations for the design of windows with these orientations are scarce. The thermal and daylighting studies indicate that it is possible to have windows to the east or west orientations with still acceptable thermal and daylighting effects as long as they comply with the following recommendations: * For a south orientation, the absolute surfaces and the fenestration should be in the medium to high range, * For an east orientation, the absolute surfaces and the fenestration should be in the medium range, * For an orientation to the west, similar recommendations may be appropriate, albeit with more carefully designed solar shading, since the probability for overheating will be higher, and * For a north orientation, the absolute surfaces and the fenestration should be in the medium to high range. As a device to control eventual glare from opposite walls, solar shading, such as light coloured curtains, are recommended.

    Global heating increases profitability of solar energy application in the Balkans. The most important market segments for wider solar cells utilization in Yugoslavia (Serbia and Montenegro) are solar pumps for irrigation in agriculture, traffic lights, lighting of weekend houses, air-conditioning, telecommunications, electric vehicles, solar hydro-electric power plants, sports centers and schools and orthodox monasteries. In addition to these applications of solar modules of relatively high capacity, a wide scope of applications of mini solar modules in consumer goods is given serious consideration (flashlights, bicycle lights, fan caps, beach hats, solar parasols, toys for children, solar watches, minicomputers, walkmans and alike). In this paper is projected gradually increase of solar cells applications in Yugoslavia, from 772 kW in 2006., to 3,901 kW installed photovoltaic power in 2010. year. The largest parts of this projected 3.9 MW in 2010., ought to be solar pumps (498 kW), telecommunications (470 kW) and traffic lights (468 kW). (orig.)

    Van den Ham, E.R.; Bosselaar, L.

    1998-01-01

    A method has been developed by means of which the contribution of passive solar energy to the Dutch energy balance can be quantified univocally. The contribution was 57 PJ in 1990 and also 57 PJ in 1995. The efficiency of passive solar energy systems increased from -31.5% to -28.1% in the period 1990-1995, mainly as a result of the use of extra insulating glazing. As a result of the reduction of energy consumption for heating in houses it is expected that the extra contribution of 2 PJ will not be realized in the year 2010. It is suggested that the method to determine the absolute contribution of passive solar energy to the energy demand of dwellings is to be included in the protocol monitoring renewable energy. For the method to be included in the energy statistics of Statistics Netherlands (CBS) it can be considered only to take into account the difference compared to 1990. 11 refs

    2013-01-01

    The long-duration of national programs has been the driving force behind the expansion of the local market of solar water heaters (SWHs) in Taiwan in the last two decades. This study examines the potential market for SWHs using the statistical data from end users and the 2010 Population and Housing Census. The current effective utilization rate of residential SWHs in terms of potential number of systems installed is estimated to be 11.8%. The analyses also show that the current national subsidy program has recently lost its momentum in expanding the market. Therefore, regional subsidy programs should become the main force in influencing the growth in sales. In addition, SWHs of larger scale would be particularly effective in industries. To promote such applications, a combination of performance-based and direct subsidy schemes or tax deductions can be offered to end users to promote the applications of SWHs in the commercial sector. Solar-assisted cooling systems are considered to be another potential application of solar energy, which is associated with energy saving and power consumption in commercial and residential buildings. A short review of the R and D activities is also given in this paper. - Highlights: ► Regional subsidy programs will be the main force in influencing the growth in sales. ► A revised program is needed to promote solar water heaters for industry applications. ► Solar-assisted cooling systems are potential applications of solar energy in Taiwan

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

  14. Housing, energy and the environment

    Energy Technology Data Exchange (ETDEWEB)

    1991-02-01

    In 1985 the Association published An Energy Policy for Housing, setting out recommendations for action by local authorities and central Government to tackle the problem of fuel poverty and the improvement of the energy efficiency of the nation's housing. Based on a survey of Association members and discussions with other relevant organisations, the report then concluded that, ''the Government has yet to demonstrate any real commitment to positive investment in an energy efficient housing stock''. Five years later, the Association decided to undertake another survey to establish the extent to which its recommendations have been acted upon and to assess other factors which might have affected the achievement of any energy efficient housing stock. This report is the result of that new survey and it shows that, whilst many more authorities have made progress in developing good practice, much local authority housing is still energy inefficient and many low income households still suffer from fuel poverty.

    In five brief articles product information is given on solar energy applications with special attention to the Netherlands. After an introduction on solar energy availability in the Netherlands the developments in solar boiler techniques are dealt with. Solar water heaters have advantages for the environment, and government subsidies stimulate different uses of such water heaters. Also the developments of solar cells show good prospects, not only for developing countries, but also for the industrialized countries. In brief the developments in solar energy storage and the connection of solar equipment to the grid are discussed. Finally attention is paid to the applications of passive solar energy in the housing construction, the use of transparent thermal insulation and the developments of translucent materials. 18 figs., 18 ills.

  18. Passive houses in Sweden. Experiences from design and construction phase

    Energy Technology Data Exchange (ETDEWEB)

    Jansson, Ulla

    2008-07-01

    The sector of residential buildings and service organizations uses 36% of the total energy in Sweden. In June 2006, it was decided by the Swedish parliament that the energy use in residential buildings and premises should decrease by 20% per heated unit area before 2020. To reach this goal, more energy efficient buildings must be produced as well as energy efficient improvements must be performed on the existing building stock. One way to reduce the energy use in buildings is to build passive houses. A passive house is a mechanically ventilated building that with a highly insulated and air tight building envelope uses a minimum of energy for heating. The method used in this research is to practically participate in four passive house demonstration projects. The results expected are to find guiding principles and tools needed for passive house planning and make the system solutions usable for planning in more general terms. Joining as a part of the planning group; advice and help is given to architects, consultants and to the client. The demonstration projects studied are located in the south-west of Sweden. Three of the projects are new constructions and one is a renovation project. In the centre of Vanirom 40 rental apartments were built in 2005/2006 according to the passive house standard. Solar collectors on the roof contribute to the domestic hot water production. Every apartment has its own mechanical ventilation system with efficient heat recovery. Auxiliary heating is supplied by electricity. The load bearing structure were made of concrete and cast at site. The exterior walls and roof were made of wooden frame construction and mounted at site. The tenants moved in during summer 2006. The passive house project in Failure's consists of three houses with 12 rental apartments. The air is supplied by mechanical ventilation with an air to air heat exchanger, one in each apartment. The domestic hot water is prepared by solar collectors and auxiliary heating

  19. Living closer to the environment: Housing design concept

    Directory of Open Access Journals (Sweden)

    Kosorić Vesna

    2011-01-01

    Full Text Available The main idea of this design concept is to strengthen the relationship and understanding between a man - resident and his environment. Residents are separated from the outdoor environment by glazing, which enables constant observation of environment from nearly all points of indoor space, encouraging positive feelings towards external world and understanding of the fragility of biosphere. Care for the environment should become a part of a man's nature and way of living, and it is the people who are expected to become the driving force of positive global changes towards sustainable development. The semisphere-like single family house of 14m in diameter has a multifunctional, multi-layer 'active' facade envelope. The envelope ensures constant visual contact of residents with the whole surroundings, while still providing comfort. The living space of the house reflects natural shapes which are organic rather than rectangular. Such indoor space becomes a part of the environment, rather than being protected, distanced and isolated from it. The house is designed to use solar energy 'passively' by absorption through insulated glazed envelope and 'actively' by outer skin layer on the first floor, made of stripes of flat semi-transparent polycrystalline photovoltaic (PV panels. In addition to its constructive role, the concrete core of the house acts as thermal mass and enables absorption and accumulation of thermal energy. The developed housing concept is applicable in different urban-design units and sets.

    The objective of this research is to develop the elemental technology of the small and thin energy collection system from water, wind, and others in the house, and examine them at the eco-house which will be built at Tohoku University on March 2010. This small energy storage system will contribute to reduce 10% of greenhouse gas emission from household electricity. This project is done by three following groups. 1st group (NEC-Tokin Co. Ltd.) will develop the technologies on the accumulation of electric power pressured from low electric power in which electricity is generated and on the cooperation with AC power supply used for domestic use for this eco-house system. 2nd group (INAX Co. Ltd.) will develop the elemental technology of the slight energy collection system from tap water in the home using a small hydroelectric generator for this eco-house system. 3rd group (Shoei Co. Ltd.) will develop the technologies on existent magnetic gear device, health appliances (Exercise bike), wind power generator, for this eco-house system. Tokoku University compiles these groups. Furthermore, I develop a search of unused small energy and the use technology, and propose a new energy supply system using solar cell and Li ion secondary battery.

  1. Women's housing conditions in Bangladesh.

    Shefali, M K

    1996-01-01

    This news article describes women's housing conditions, housing policy, and pilot programs to house poor women in Bangladesh. Although Bangladesh has a constitution that reinforces the equal status of women, in practice, men dominate and patrilineal customs determine inheritance and property rights. Religious affiliation also determines land tenure and inheritance. Muslim women can inherit 12.5% of their husband's property if there are children. 25% is inherited if wives are without children. Hindu women without sons can inherit their husband's property, but not parental property. Many families refuse to release property to women without a fight. Women, regardless of ownership of land, rarely control or use their land. The custom of requiring men to maintain wives during the marriage, and daughters until marriage, creates obstacles to women's decision making about property. Without collateral and other security women are unable to secure bank loans. Many women are also constrained by the requirement of male consent or guarantees for bank transactions. Banks do not have a gender responsive criteria for selecting loan recipients. The government does not provide sufficient housing to satisfy the growing housing needs due to population growth. Some housing is available from slum landlords. A National Housing Policy was formulated in 1993. Priority would be given to the housing needs of low income women in urban areas and women-headed households with income below the poverty line. The policy does not address the underlying factors that prevent equal access to housing for women. The government prepared a Human Settlement and Urban Development proposal for the Habitat II conference. The plan did not address gender issues. Special efforts are being made by nongovernmental groups to meet the housing needs of professional women and for some disadvantaged women.

    Full Text Available Last few years have shown that Romania is not protected from the consequences of climate change. It is clear that type flood events may cause social problems and losses is difficult financing from public resources, especially in the context of the existence of budget constraints. The only viable system to cope with such disasters is insurance system that has the ability to spread risks by reinsurance Natural disasters - earthquakes, floods, landslides - are just some of the risks that may threaten your home. And if natural disasters can seem distant danger, think as fires, floods caused by broken pipes or theft of household goods are trouble can happen anytime to anyone. To protect yourself in such unpleasant situations, whose frequency is unfortunately on the rise, it is necessary to be assured. Thus, you will be able to recover losses in the event that they occur. The house is undoubtedly one of the most important assets we own. Therefore, the Romans began to pay increasingly more attention to domestic insurance products. Since 2011, voluntary home insurance, life insurance with, were the most dynamic segments of the market.

    While wind power is widely acknowledged as the most developed of the 'new' renewables, the number two technology, in terms of installed capacity functioning worldwide, is solar heating, or solar thermal. The author has investigated recent industry reports on how these markets are developing. The authors of an International Energy Agency (IEA) survey studied 41 countries in depth at the end of 2004, revealing that 141 million m 3 - corresponding to an installed capacity of 98.4 GWth - were installed in the sample countries (these nations represent 3.74 billion people, about 57% of the world's population). The installed capacity within the areas studied represents approximately 85%-90% of the solar thermal market worldwide. The use of solar heating varies greatly between countries - even close neighbours - and between economic regions. Its uptake often has more to do with policy than solar resource. There is also different uptake of technology. In China, Europe and Japan, plants with flat-plate and evacuated tube collectors are used, mainly to heat water and for space heating.

    1992-10-01

    In order to use solar energy now and in the future several measures should be taken in the field of urban development and housing construction. A number of policy instruments is available to the local governments to stimulate the use of solar energy. However, little use is made of these possibilities so far. In many municipalities there are uncertainties about the financial consequences of solar energy conscious building. In practice it appears that there are hardly any extra costs for the infrastructure if building blocks and roofs are designed and built with south orientation. Also possibilities to minimize the investment barrier for the occupants of the houses are available. An overview is presented of the policy instruments and practical examples are given for the Dutch municipalities Gouda, Schiedam, Heerhugowaard, Delft and Haarlemmermeer. 2 tabs., 2 appendices, 6 refs

    The nature of solar radiation and its variation with location is described. The distribution of energy in the solar spectrum places immediate limits on the theoretical efficiency of conversion processes, since practical absorbers cannot convert all wavelengths received to useful energy. The principles of solar energy conversion methods are described. Absorption of solar energy can give rise to direct electrical generation, heating, or chemical change. Electrical generation from sunlight can be achieved by photovoltaic systems directly or by thermal systems which use solar heat to drive a heat engine and generator. The technology used and under research for promising ways of producing electricity or fuel from solar energy is described. Photovoltaic technology is established today for remote area, small power applications, and photovoltaic module sales alone are over 100 million dollars per year at present. The photovoltaic market has grown steadily since the mid-1970's, as prices have fallen continuously. Future energy options are briefly described. The merits of a sustainable energy economy, based on renewable energy resources, including solar energy, are emphasized, as this seems to provide the only hope of eliminating the problems caused by the build-up of atmospheric carbon dioxide, acid rain pollution and nuclear waste disposal. There is no doubt that clean fuels which were derived from solar energy and either did not involve carbon dioxide and used atmospheric carbon dioxide as the source dioxide as the source of carbon would be a worthy ideal. Methods described could one day achieve this.

    The XXI century home should be a digital habitat, a connected residence, but at the same time it should be involved in sustainability and the environment. The location of new technologies at home, and its acceptance by the user, requires, among other actions, a significant diffusion and activity to be undertaken. This work proposes the development of a Smart House network designed for its integration into a sustainable and bioclimatic solar house. The paper focuses on a specific aspect of the house design, the control system bus, developed for the management of the different parameters, variables, sensors and actuators which coexist at home. Finally, the system has been installed in a laboratory bioclimatic house. Environmental variable experiments based on the control of passive elements, such as phase shift gels, are presented. Experimental results show that the system is able to benefit from the bioclimatic elements in the house by taking into account the user preferences.

    Solar MHD is an important tool for understanding many solar phenomena. It also plays a crucial role in explaining the behaviour of more general cosmical magnetic fields and plasmas, since the Sun provides a natural laboratory in which such behaviour may be studied. While terrestrial experiments are invaluable in demonstrating general plasma properties, conclusions from them cannot be applied uncritically to solar plasmas and have in the past given rise to misconceptions about solar magnetic field behaviour. Important differences between a laboratory plasma on Earth and the Sun include the nature of boundary conditions, the energy balance, the effect of gravity and the size of the magnetic Reynolds number (generally of order unity on the Earth and very much larger on the Sun). The overall structure of the book is as follows. It begins with two introductory chapters on solar observations and the MHD equations. Then the fundamentals of MHD are developed in chapters on magnetostatics, waves, shocks, and instabilities. Finally, the theory is applied to the solar phenomena of atmospheric heating, sunspots, dynamos, flares, prominences, and the solar wind. (Auth.)

    This final report summarizes the work conducted by the Building America Industrialized Housing Partnership (www.baihp.org) for the period 9/1/99-6/30/06. BAIHP is led by the Florida Solar Energy Center of the University of Central Florida and focuses on factory built housing. In partnership with over 50 factory and site builders, work was performed in two main areas--research and technical assistance. In the research area--through site visits in over 75 problem homes, we discovered the prime causes of moisture problems in some manufactured homes and our industry partners adopted our solutions to nearly eliminate this vexing problem. Through testing conducted in over two dozen housing factories of six factory builders we documented the value of leak free duct design and construction which was embraced by our industry partners and implemented in all the thousands of homes they built. Through laboratory test facilities and measurements in real homes we documented the merits of 'cool roof' technologies and developed an innovative night sky radiative cooling concept currently being tested. We patented an energy efficient condenser fan design, documented energy efficient home retrofit strategies after hurricane damage, developed improved specifications for federal procurement for future temporary housing, compared the Building America benchmark to HERS Index and IECC 2006, developed a toolkit for improving the accuracy and speed of benchmark calculations, monitored the field performance of over a dozen prototype homes and initiated research on the effectiveness of occupancy feedback in reducing household energy use. In the technical assistance area we provided systems engineering analysis, conducted training, testing and commissioning that have resulted in over 128,000 factory built and over 5,000 site built homes which are saving their owners over $17,000,000 annually in energy bills. These include homes built by Palm Harbor Homes, Fleetwood, Southern Energy

    The utilisation possibilities of solar energy for the energy supplying of buildings are becoming increasingly more significant. Solar research at the moment aims predominantly with a high level of efficiency and therefore making accessible a significant range of applications for solar technology. Parallel to this are attempts to effect the saving of energy, be it in the demand for energy-saving constructions or in the increasing development and application of rational energy utilisation by technologists. The most important point of these activities at the moment, is still technological methods.

    The solar energy is produced by a series of nuclear reactions taking place in the deep interior of the sun. Some of these reactions produce neutrinos which may be detected, the proper detection system being available. The results of the Davis experiment (with 37 Cl) are given, showing a deficiency in the solar neutrino flux. The relevant explanation is either a property of the neutrino or an important change in the physics of the solar models. The prospect of a new experiment (with 71 Ga) is important as it will decide which of the two explanations is correct [fr

  17. Housing First or no housing? Housing and homelessness at the end of alcohol and drug treatment.

    The rate of alcohol and drug dependency is high among homeless persons in Norway as well as in other Western societies. National homeless surveys also show a certain correlation between discharge from institutions and homelessness. However, the rate of homelessness versus the rate with fixed abode at the end of specialised alcohol and drug treatment has not been examined using quantitative methods. A cross-sectional survey was conducted in alcohol and drug treatment units in the national health services and private clinics. The survey investigates the housing outcome at the end of treatment compared to the situation at the start of treatment using an individual questionnaire for patients ending treatment in a specific time window. Housing outcome is measured by the odds ratio of having a fixed abode at the end of treatment in relation to main intoxicating substance, type of treatment (in- and outpatient), completing versus cutting short the treatment, housing situation at the start of treatment, socioeconomic capital, mental health problems, individual plan, medical assisted treatment, and a set of background variables. The housing versus homeless situation hardly changes during the treatment period. In both a bivariate analysis and a simple multivariate model, principal intoxicating substance is the strongest predictor of having a fixed abode both before and after treatment. However, a more sophisticated analysis indicates that socioeconomic resources and social capital play along with the preferred intoxicating substance as predictors of having permanent housing. After more than a decade of a housing-led national homeless policy, and wide embracement of Housing First approaches in the European Union, homeless persons entering specialised alcohol and drug treatment are likely to return to the streets and hostels at the end of treatment. Access to housing after treatment is very limited for those lacking resources to solve their housing problem without assistance

    Rea Ventures Group, LLC (Rea Ventures) partnered with Southface Energy Institute (Southface)—a member of the U.S. Department of Energy’s Partnership for Home Innovation Building America research team—to rehabilitate 418 low-income multifamily rental apartments located at 14 properties in Georgia (International Energy Conservation Code Climate Zones 2–4). These 22-year-old units with individual utility meters were arranged in row house or townhouse style. Rehabilitation plans were developed using a process prescribed by the U.S. Department of Agriculture (USDA) Rural Development program, which partially funded the building upgrades. The USDA is responsible for building, upgrading, and subsidizing housing in rural areas nationwide; this housing includes more than 14,000 existing multifamily housing developments. In 2012, more than $100 million in grants and loans were allocated for that purpose.
