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

International Nuclear Information System (INIS)

Golubchikov, Oleg; Deda, Paola

2012-01-01

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

The Space House TM : Space Technologies in Architectural Design

Gampe, F.; Raitt, D.

2002-01-01

The word "space" has always been associated with and had a profound impact upon architectural design. Until relatively recently, however, the term has been used in a different sense to that understood by the aerospace community - for them, space was less abstract, more concrete and used in the context of space flight and space exploration, rather than, say, an empty area or space requiring to be filled by furniture. However, the two senses of the word space have now converged to some extent. Interior designers and architects have been involved in designing the interior of Skylab, the structure of the International Space Station, and futuristic space hotels. Today, architects are designing, and builders are building, houses, offices and other structures which incorporate a plethora of new technologies, materials and production processes in an effort not only to introduce innovative and adventurous ideas but also in an attempt to address environmental and social issues. Foremost among these new technologies and materials being considered today are those that have been developed for and by the space industry. This paper examines some of these space technologies, such as energy efficient solar cells, durable plastics, air and water filtration techniques, which have been adapted to both provide power while reducing energy consumption, conserve resources and so on. Several of these technologies have now been employed by the European Space Agency to develop a Space House TM - the first of its kind, which will be deployed not so much on planets like Mars, but rather here on Earth. The Space House TM, which exhibits many innovative features such as high strength light-weight carbon composites, active noise-damped, (glass and plastic) windows, low-cost solar arrays and latent heat storage, air and water purification systems will be described.

The challenges facing electric utilities regarding a shortage of highly qualified labour to maintain, refurbish and expand electrical infrastructure can be attributed to a wave of retirements in skilled employees, a shortage of entry-level workers and a rapidly increasing workload caused by investment in electricity infrastructure. Two solutions were presented for finding and sustaining an adequate personnel base. The first involved developing local talent, both entry-level and mid-career staff to ensure that work continuity and workplace safety are maintained. The second involved the implementation of technological solutions to help optimize the use of existing and future labour resources. This paper presented the human resource programs developed by Hydro One, the largest electrical transmission and distribution utility in the province of Ontario. Their initiatives include raising the profile of the utility work environment through strategic partnerships with educational institutions and developing in house offerings to supplement existing academic programs. This paper also presented a technical solution to address the resources challenges specifically associated with power system protection and control. The solution targets professional and skilled trades involved in the design, installation and maintenance of automated substations and protection and control systems. It is based on the premise that resource optimization can be achieved by reducing inconsistent design and construction practices and replacing these designs with highly standardized materials with digital communications using IEC 61850. This new technology should attract young professionals to the power engineering field while still maintaining a high comfort level with the established professional workforce. 5 refs., 4 figs.

Occupants’ Utilization of Natural Ventilation: A Study of Selected Terrace House Designs in Hot-humid Climate

Directory of Open Access Journals (Sweden)

Ibiyeye AI

2015-05-01

Full Text Available With increased time spent indoors and demand for enhanced comfort levels, energy consumption in homes is rising mostly for cooling, particularly in hot-humid regions. Natural ventilation is seen as an alternative to mechanical cooling as it is totally independent on energy and has been reported to be of high potential. However, little information is available on the utilization of natural ventilation in individual living spaces in different house designs. Therefore, this paper aims to investigate occupants’ utilization of natural ventilation in living spaces under different terrace house designs in hot-humid climate and also the relationship between the openings and occupants’ satisfaction with natural ventilation. Five (5 different terrace house types in Putrajaya, Malaysia with different opening design characteristics were selected for the study. A total of 298 households from these house types were surveyed and results show that occupants mostly open their windows during the daytime to capture breeze from outside despite the fact that they owned air-conditioners. In terms of occupants’ level of satisfaction with indoor ventilation when utilizing natural ventilation, majority rated neither satisfied nor unsatisfied. Further regression analysis reveals that this level of satisfaction is significantly related to opening sizes that are in accordance with the law, duration of opening windows and AC ownership. Findings from this study will shed more light on behavioural pattern of occupants of residential buildings towards natural ventilation provisions and highlight the importance of conforming to the law governing them.

Performing accountability: Making environmental credentials visible in housing design

International Nuclear Information System (INIS)

Shaw, Isabel; Ozaki, Ritsuko

2015-01-01

Making housing developments ‘environmentally sustainable’ requires housing developers to be accountable for their ‘green’ credentials. Accountability is promoted by both the UK government's environmental policy for housing design – the Code for Sustainable Homes – and local councils in their planning criteria. These accountability practices are key to how relationships between housing professionals and local planning authorities influence practices and outcomes of environmental sustainability. In this article, we examine how accountability is performed in housing design and development. We argue that accountability practices involve the management of making environmental sustainability visible through demonstrating the utilization of sustainable technologies. We contend that these ‘visibility’ practices are carried out to the detriment of an appreciation of how energy is both provided and consumed. We contend that using the installation phase of sustainable technologies as a point of adequate assessment of the environmental effectiveness of a building is short-sighted. Policy needs to look beyond this, and consult with professionals who develop and sell houses to understand better their working priorities and contexts that shape the provision of renewable energy in the planning phase and post-build. - Highlights: • Accountability practices shape environmental sustainability practices and outcomes. • Making sustainability ‘visible’ involves the use of sustainable technologies. • Policy should consider how it affects professionals work and energy provision. • Visibility practices influence energy provision and potential consumption.

2000-01-01

The cell house environment is very challenging with regard to protection of the concrete structure and components against the corrosive effects of acid. Coating technology using Epoxy, Vinyl Ester and Polyurethane Polymers is available, to provide the necessary chemical and heat resistance. However, producing suitable POLYMER CONCRETE technology for pre-cast components, especially tanks and cells requires not only the correct POLYMER selection, but also significant know-how in mineral aggregate technology to achieve the desired performance properties. Furthermore, the POLYMER CONCRETE technology must enable the pre-caster to manufacture the components in a simple one-step procedure. This paper outlines the important aspects in formulating POLYMER CONCRETE, the performance properties that can be achieved and the practical issues relating to the cost effective pre-casting of tanks and cells in particular.

Anxiety and depression in socioeconomically disadvantaged older adults frequently go unrecognized and untreated. This study aims to characterize mental illness and its treatment in older adult public housing residents who have many risk factors for anxiety and depression. Cross-sectional study. Public housing high-rises in Rochester, New York. One hundred ninety residents aged 60 years and older. Anxiety and depression were assessed using the Structured Clinical Interview for the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, GAD-7, and Patient Health Questionnaire. We obtained information on mental healthcare from medication review and self-report. Participants had a median age of 66 years, 58% were women, 80% were black, and 92% lived alone. Many participants (31%) were in need of mental healthcare: 21% had syndromal and 11% had subsyndromal anxiety or depression. Mental healthcare need was associated with younger age; intact cognitive functioning; impairments in instrumental activities of daily living (IADL); more medical illness; decreased mobility; smaller social network size; more severe life events; and increased utilization of medical, human, and informal services. Of those with mental healthcare need, most were not receiving it. Compared with residents receiving mental healthcare, residents with untreated need were more likely to be men and have less IADL impairment, medical illness, severe life events, onsite social worker use, and human services utilization. Mental illness was common and largely untreated in public housing residents. Increasing collaboration between medical, mental, and human services is needed to improve identification, treatment, and ultimately prevention of late-life mental illness in this community setting.

ETHICS OF SMART HOUSE WELFARE TECHNOLOGY FOR OLDER ADULTS: A SYSTEMATIC LITERATURE REVIEW.

Science.gov (United States)

Sánchez, Veralia Gabriela; Taylor, Ingrid; Bing-Jonsson, Pia Cecilie

2017-01-01

The University College of Southeast Norway has an on-going project to develop a smart house welfare system to allow older adults and people with disabilities to remain in their homes for as long as they wish in safe, dignified, living conditions. This article reviews reported ethical challenges to implementing smart houses for older adults. A systematic literature review identified twenty-four articles in English, French, Spanish, and Norwegian, which were analyzed and synthesized using Hofmann's question list to investigate the reported ethical challenges. Smart houses offer a promising way to improve access to home care for older adults and people with disabilities. However, important ethical challenges arise when implementing smart houses, including cost-effectiveness, privacy, autonomy, informed consent, dignity, safety, and trust. The identified ethical challenges are important to consider when developing smart house systems. Due to the limitations of smart house technology, designers and users should be mindful that smart houses can achieve a safer and more dignified life-style but cannot solve all the challenges related to ageing, disabilities, and disease. At some point, smart houses can no longer help persons as they develop needs that smart houses cannot meet.

Supportive housing, defined as subsidized housing in conjunction with site-based social services, may help improve the health and residential stability of highly disadvantaged individuals. This study examined changes in health status, quality of life, substance use, health care utilization, and residential stability among 112 homeless and vulnerably housed individuals who applied to a supportive housing program in Toronto, Canada, from December 2005 to June 2007. Follow-up interviews were conducted every 6 months for 18 months. Comparisons were made between individuals who were accepted into the program (intervention) and those who were wait-listed (usual care) using repeated-measures analyses. Individuals who were accepted into the housing program experienced significantly greater improvements in satisfaction with living situation compared with individuals in the usual care group (time, F(3,3,261) = 47.68, p life measures, health status, health care utilization, or substance use between the two groups over time. Significant improvement in residential stability occurred over time, independent of assigned housing group (time, F(3,3,261) = 9.96, p housing on homeless individuals was limited by the small number of participants who were literally homeless at baseline and by the large number of participants who gained stable housing during the study period regardless of their assigned housing status. Nonetheless, this study shows that highly disadvantaged individuals with a high prevalence of poor physical and mental health and substance use can achieve stable housing.

The technical development of clean energy including the utilization of solar energy was begun in 1973 at the time of the oil crisis, and about 20 years elapsed. Also in Japan, the electric power buying system by electric power companies for solar light electric power and wind electric power has been started in 1992, namely their value as a merchandise was recognized. As for these two technologies, the works of making the international standards and JIS were begun. The range of clean energy or natural energy is wide, and its kinds are many. The utilization of solar heat and the electric power generation utilizing waves, tide and geotherm already reached the stage of practical use. Generally in order to practically use new energy, the problem of price must be solved, but the price is largely dependent on the degree of spread. Also the reliability, durability and safety must be ensured, and the easiness of use, effectiveness and trouble-saving maintenance and operation are required. For the purpose, it is important to packaging those skillfully in a system. The cases of intelligent natural energy systems are shown. Solar light and wind electric power generation systems and the technology of transporting clean energy are described. (K.I.)

Almost all companies are now utilizing computer networks to support speedier and more effective in-house information-sharing and communication. However, existing systems are designed to support communications only within the same department. Therefore, in our research, we propose an in-house communication support system which is based on the “Information Propagation Model (IPM).” The IPM is proposed to realize word-of-mouth communication in a social network, and to support information-sharing on the network. By applying the system in a real company, we found that information could be exchanged between different and unrelated departments, and such exchanges of information could help to build new relationships between the users who are apart on the social network.

Allen, B

1996-04-01

It is now commonly accepted that 'Smart House' technology can play a significant part in helping both elderly and disabled people enjoy a greater degree of independence in the near future. In order to realize this aspiration, it is necessary to examine a number of factors: the development of the appropriate Home Bus technologies and supported devices; the development of the appropriate user interfaces that will allow people with a range of special needs use the system; the incorporation of the requirements of the 'Smart House' controller with the other technological needs of the user; and the development of mainstream technologies that will affect the cost and availability of devices to the user. This paper will examine the above points and suggest appropriate actions and trends. It will draw upon the work of a four-member consortium currently finalizing a technical development project under the EC TIDE program, the experience of research and commercial organizations engaged in development work in associated areas and the experiences of the Dublin-based, Central Remedial Clinic and in particular, its Client Technical Services Unit. The CTSU have been actively engaged in the development of systems for clients and direct clinical assessments for the last 12 years.

There is a healthy public policy agenda investigating the health impacts of improving living conditions. However, there are few economic evaluations, to date, assessing value for money. We conducted the first cost-effectiveness analysis of a nationwide intervention transferring social and private tenants to new-build social housing, in Scotland. A quasi-experimental prospective study was undertaken involving 205 intervention households and 246 comparison households, over 2 years. A cost-utility analysis assessed the average cost per change in health utility (a single score summarising overall health-related quality of life), generated via the SF-6D algorithm. Construction costs for new builds were included. Analysis was conducted for all households, and by family, adult and elderly households; with estimates adjusted for baseline confounders. Outcomes were annuitised and discounted at 3.5%. The average discounted cost was £18, 708 per household, at a national programme cost of £ 28.4 million. The average change in health utility scores in the intervention group attributable to the intervention were +0.001 for all households, +0.001 for family households, -0.04 for adult households and -0.03 for elderly households. All estimates were statistically insignificant. At face value, the interventions were not value for money in health terms. However, because the policy rationale was the amenity provision of housing for disadvantaged groups, impacts extend beyond health and may be fully realised over the long term. Before making general value-for-money inferences, economic evaluation should attempt to estimate the full social value of interventions, model long-term impacts and explicitly incorporate equity considerations.

In verifying the effectiveness of the deep geothermal resource exploration technology, development is being carried out on a fracture-type reservoir exploration method. The seismic exploration method investigates detailed structures of underground fracture systems by using seismic waves generated on the ground surface. Verification experiments for fiscal 1994 were carried out by selecting the Kakkonda area in which small fracture networks form reservoir beds. Geothermal resources in deep sections (deeper than 2000 m with temperatures higher than 350{degree}C) are promising in terms of amount of the resources, but anticipated with difficulty in exploration and impediments in drilling. To avoid these risks, studies are being progressed on the availability of resources in deep sections, their utilization possibility, and technologies of effective exploration and drilling. This paper summarizes the results of deep resource investigations during fiscal 1994. It also describes such technological development as hot water utilizing power generation. Development is performed on a binary cycle power generation plant which pumps and utilizes hot water of 150 to 200{degree}C by using a downhole pump. The paper also reports development on element technologies for hot rock power generation systems. It also dwells on development of safe and effective drilling and production technologies for deep geothermal resources.

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)

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.

One of the constant challenges facing the research community is the identification of technology needs 5 to 15 years from now. A look back into history indicates that the forces driving natural gas research have changed from decade to decade. In the 1970s research was driven by concerns for adequate supply; in the 1980s research was aimed at creating new markets for natural gas. What then are the driving forces for the 1990s? Recent reports from the natural gas industry have helped define a new direction driven primarily by market demand for natural gas. A study prepared by the Interstate Natural Gas Association of America Foundation entitled ''Survey of Natural Research, Development, and Demonstration RD ampersand D Priorities'' indicated that in the 1990s the highest research priority should be for natural gas utilization and that technology development efforts should not only address efficiency and cost, but environmental and regulatory issues as well. This study and others, such as the report by the American Gas Association (A.G.A.) entitled ''Strategic Vision for Natural Gas Through the Year 2000,'' clearly identify the market sectors driving today's technology development needs. The biggest driver is the power generation market followed by the industrial, transportation, appliance, and gas cooling markets. This is best illustrated by the GRI 1994 Baseline Projection on market growth in various sectors between the year 1992 and 2010. This paper highlights some of the recent technology developments in each one of these sectors

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

International Nuclear Information System (INIS)

Schaffrin, André; Reibling, Nadine

2015-01-01

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

DYNAMIC PLANNING INDICATORS FOR OPTIMISING THE ENERGY MODERNISATION OF RESIDENTIAL HOUSING STOCK

2016-01-01

Full Text Available Objectives. In the article, the problem of the optimisation of the energy modernisation of residential housing is examined. Methods. A mathematical model for the optimisation of energy use is developed with the use of dynamic programming techniques. Results. The proposed method of assessing the effectiveness of comprehensive energy-saving measures can improve the quality of decision-making on housing recovery and increase its energy modernisation. The application of mathematical modeling allows for the distribution of funds to projects so that the implementation of organisational and technological solutions consistently implement measures that will lead to optimal social and economic effects. The developed mathematical model also allows the amount of quality housing to be maximised through the implementation of energy-saving and other measures when upgrading the housing stock. Problems concerning the renovation of housing stock are analysed. The concept of housing energy modernisation is introduced. The principal energysaving technologies in housing modernisation are distinguished. A schema for the optimal allocation of funds for energy-saving measures is described. It is assumed that the optimal solution is obtained independently of the number of steps and the initial supply of invested capital.Conclusion.

The Airlie House Pollution Prevention Technology Transfer Projects were a series of pilot projects developed for the US Department of Energy with the intention of transferring pollution prevention technology to the private sector. The concept was to develop small technology transfer initiatives in partnership with the private sector. Argonne National Laboratory developed three projects: the microscale chemistry in education project, the microscale cost benefit study project, and the Bethel New Life recycling trainee project. The two microscale chemistry projects focused on introducing microscale chemistry technologies to secondary and college education. These programs were inexpensive to develop and received excellent evaluations from participants and regulators. The Bethel New Life recycling trainee project provided training for two participants who helped identify recycling and source reduction opportunities in Argonne National Laboratory's solid waste stream. The pilot projects demonstrated that technology transfer initiatives can be developed and implemented with a small budget and within a short period of time. The essential components of the pilot projects were identifying target technologies that were already available, identifying target audiences, and focusing on achieving a limited but defined objective

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.

The most important greenhouse gas is CO{sub 2} from coal utilization. Ways of mitigating CO{sub 2} emissions include the use of alternative fuels, using renewable resources and increasing the efficiency of power generation and end use. Adding to such greenhouse gas mitigation technologies, post combustion control by removing CO{sub 2} from power station flue gases and then storing or disposing it will be available. Although the post combustion control have to be evaluated in a systematic manner relating them to whether they are presently available technology, to be available in the near future or long term prospects requiring considerable development, it is considered to be a less promising option owing to the high cost and energy penalty. By contrast, abatement technologies aimed at improving conversion efficiency or reducing energy consumption will reduce emissions while having their own commercial justification.

The introduction of digital technologies into the nuclear industry has assisted in many ways and made many of the Life Extensions and Uprates a possibility. But with this introduction of digital technologies comes some potentially challenging issues which need to be addressed for ultimate project success. This presentation discusses what a nuclear utility should consider and establish when implementing digital technologies in their plant. Digital technologies have been employed in many safety critical industries such as Aerospace, Pharmaceutical, Oil and Gas, and Chemical. However, nuclear industry implementation of digital technologies has been slow and in many ways tenuous. There are even documented operating experience events in which plant trips/SCRAMs occurred during a digital system implementation. This presentation aims to prevent those issues drawing upon the lessons learned over the past 5 years. Considerations include general challenges to overcome when implementing Digital Technologies, how to justify and execute projects, evaluation of resource knowledge, and the new challenges of Cyber Security.

Conceptual and Empirical Themes regarding the Design of Technology Transfer Programs: A Review of Wood Utilization Research in the United States

Full Text Available Transfer of technologies produced by research is critical to innovation within all organizations. The intent of this paper is to take stock of the conceptual underpinnings of technology transfer processes as they relate to wood utilization research and to identify conditions that promote the successful transfer of research results. Conceptually, research utilization can be viewed from multiple perspectives, including the haphazard diffusion of knowledge in response to vague and imprecise demands for information, scanning of multiple information sources by individuals and organizations searching for useful scientific knowledge, engagement of third parties to organize research results and communicate them to potential users, and ongoing and active collaboration between researchers and potential users of research. Empirical evidence suggests that various types of programs can promote technology transfer (venture capital, angel investors, business incubators, extension services, tax incentives, and in-house entities, the fundamental effectiveness of which depends on research results that are scientifically valid and consistent with the information needs of potential users. Furthermore, evidence suggests preference toward programs that are appropriately organized and governed, suitably led and creatively administered, and periodically evaluated in accordance with clear standards of success.

Urban housing experiments in Yugoslavia 1948-1970

Full Text Available In the period from 1948 to 1970 urban housing architecture in Yugoslavia had a distinctly experimental character as it strived intensively towards research and establishment of new architectural patterns and values that would mark the period of economic growth of the country. In conditions of mass housing construction, initiated by the devastated urban housing fund after the Second World War, significant influx of population to towns and the state directed its socialist aspirations at alloting every family acceptable living space. The period of the so-called “directed housing construction“, whose imperative was to establish the limits of existential minimum in collective housing, maximal space “packing“ and optimal functionality of flats, at the same time represents the most significant period in the development of housing architecture in Yugoslavia. The architects focused their interests in housing in mainly three directions: a the creation and application of new prefabrication systems, b innovative application of modernistic patterns in aestheticization of architecture and c experimenting with space units which will enable a higher level of privacy in high-density housing conditions. The first direction of research emerged in the context of post-war housing construction of a wide scope, which encouraged the advance of technological research in areas of prefabrication and practical application of achieved results on the whole territory of Yugoslavia. The second direction dealt with architectural planning which was strictly subordinated to social and ideological sphere with domineering socialist monumentalism and artistic and sculptural approach to architecture. The third was related to experimental tendency with new urban housing patterns which aimed to search and find more pragmatic, humane solutions within mass high-density housing constructions which were the first to utilize and show examples of “double-tract” buildings.

Strategic rigidity and foresight for technology adoption among electric utilities

International Nuclear Information System (INIS)

Shah, Arsalan Nisar; Palacios, Miguel; Ruiz, Felipe

2013-01-01

The variation in the adoption of a technology as a major source of competitive advantage has been attributed to the wide-ranging strategic foresight and the integrative capability of a firm. These possible areas of competitive advantage can exist in the periphery of the firm's strategic vision and can get easily blurred as a result of rigidness and can permeate in the decision-making process of the firm. This article explores how electric utility firms with a renewable energy portfolio can become strategically rigid in terms of adoption of newer technologies. The reluctance or delay in the adoption of new technology can be characterized as strategic rigidness, brought upon as a result of a firm's core competence or core capability in the other, more conventional technology arrangement. This paper explores the implications of such rigidness on the performance of a firm and consequently on the energy eco-system. The paper substantiates the results by emphasizing the case of Iberdrola S.A., an incumbent firm as a wind energy developer and its adoption decision behavior. We illustrate that the very routines that create competitive advantage for firms in the electric utility industry are vulnerable as they might also develop as sources of competitive disadvantage, when firms confront environmental change and uncertainty. - Highlights: • Present a firm-level perspective on technology adoption behavior among electric utilities. • Firms with mature technology can become rigid towards newer technologies. • Case study analysis of a major electric utility firm. • Implications of ‘technology rigidness’ on the energy eco-system

With the gradual maturity of the real estate market in China, urban housing prices are also better able to reflect changes in market demand and the commodity property of commercial housing has become more and more obvious. Many scholars in our country have made a lot of research on the factors that affect the price of commercial housing in the city and the number of related research papers increased rapidly. These scholars’ research results provide valuable wealth to solve the problem of urban housing price changes in our country. However, due to the huge amount of literature, the vast amount of information is submerged in the library and cannot be fully utilized. Text mining technology has been widely concerned and developed in the field of Humanities and Social Sciences in recent years. But through the text mining technology to obtain the influence factors on the price of urban commercial housing is still relatively rare. In this paper, the research results of the existing scholars were excavated by text mining algorithm based on support vector machine in order to further make full use of the current research results and to provide a reference for stabilizing housing prices.

Studies have examined the potential benefits and risks of alternative forms of detention, such as house arrest, for adults but, despite its growing use, little research has examined the implications of house arrest for juveniles. The current research examined the experience of 14 adolescents under house arrest. Six main themes were identified in the narratives of the participants: the experience of detention, daily schedule and utilization of time, emotions and self-reflection, relationships with peers, relation to parents and supervisor(s), and contact with professionals. Findings emphasized the potential developmental dangers of house arrest at the critical stage of adolescence. Yet, analysis also showed that the period of house arrest has the potential to be a period of positive changes, and can be used for successful rehabilitation.

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

2018-03-01

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

The Long-Term Program for Research, Development and Utilization of Nuclear Energy established by the Atomic Energy Commission of Japan asserts that Japan will promote systematic utilization of MOX fuel in LWRs. Based on this Japanese nuclear energy policy, we have been pushing development of MOX fuel technology aimed at future full scale utilization of this fuel in BWRs. In this paper, the main R and D topics are described from three subject areas, MOX core and fuel design, MOX fuel irradiation behaviour, and MOX fuel fabrication technology. For the first area, we explain the compatibility of MOX fuel with UO 2 core, the feasibility of the full MOX core, and the adaptability of MOX design methods based on a mock-up criticality experiment. In the second, we outline the Tsuruga MOX irradiation program and the DOMO program, and suggest that MOX fuel behaviour is comparable to ordinary BWR UO 2 fuel behaviour. In the third, we examine the development of a fully automated MOX bundle assembling apparatus and its features. (author). 14 refs, 11 figs, 3 tabs

2018-02-01

Torrefaction is an emerging technology also called mild pyrolysis, which has been explored for the pretreatment of biomass to make the biomass more favorable for further utilization. Dry torrefaction (DT) is a pretreatment of biomass in the absence of oxygen under atmospheric pressure and in a temperature range of 200-300 degrees C, while wet torrrefaction (WT) is a method in hydrothermal or hot and high pressure water at the tempertures within 180-260 degrees C. Torrrefied biomass is hydrophobic, with lower moisture contents, increased energy density and higher heating value, which are more comparable to the characteristics of coal. With the improvement in the properties, torrefied biomass mainly has three potential applications: combustion or co-firing, pelletization and gasification. Generally, the torrefaction technology can accelerate the development of biomass utilization technology and finally realize the maximum applications of biomass energy.

Cording, Dean

2002-12-01

The 'Internet boom' of the past few years has spurred the development of a number of technologies to provide services such as secure communications, reliable messaging, information publishing and application distribution for commercial applications. Over the same period, a new generation of computer languages have also developed to provide object oriented design and development, improved reliability, and cross platform compatibility. Whilst the business models of the 'dot.com' era proved to be largely unviable, the technologies that they were based upon have survived and have matured to the point were they can now be utilized to build secure, robust and complete observatory control control systems. This paper will describe how Electro Optic Systems has utilized these technologies in the development of its third generation Robotic Observatory Control System (ROCS). ROCS provides an extremely flexible configuration capability within a control system structure to provide truly autonomous robotic observatory operation including observation scheduling. ROCS was built using Internet technologies such as Java, Java Messaging Service (JMS), Lightweight Directory Access Protocol (LDAP), Secure Sockets Layer (SSL), eXtendible Markup Language (XML), Hypertext Transport Protocol (HTTP) and Java WebStart. ROCS was designed to be capable of controlling all aspects of an observatory and be able to be reconfigured to handle changing equipment configurations or user requirements without the need for an expert computer programmer. ROCS consists of many small components, each designed to perform a specific task, with the configuration of the system specified using a simple meta language. The use of small components facilitates testing and makes it possible to prove that the system is correct.

Urban safety-net clinics are considered prime targets for the adoption of health information technology innovations; however, little is known about their utilization in such safety-net settings. Current scholarship provides limited guidance on the implementation of health information technology into safety-net settings as it typically assumes that adopting institutions have sufficient basic resources. This study addresses this gap by exploring the unique challenges urban resource-poor safety-net clinics must consider when adopting and utilizing health information technology. In-depth interviews (N = 15) were used with key stakeholders (clinic chief executive officers, medical directors, nursing directors, chief financial officers, and information technology directors) from staff at four clinics to explore (a) nonhealth information technology-related clinic needs, (b) how health information technology may provide solutions, and (c) perceptions of and experiences with health information technology. Participants identified several challenges, some of which appear amenable to health information technology solutions. Also identified were requirements for effective utilization of health information technology including physical infrastructural improvements, funding for equipment/training, creation of user groups to share health information technology knowledge/experiences, and specially tailored electronic billing guidelines. We found that despite the potential benefit that can be derived from health information technologies, the unplanned and uninformed introduction of these tools into these settings might actually create more problems than are solved. From these data, we were able to identify a set of factors that should be considered when integrating health information technology into the existing workflows of low-resourced urban safety-net clinics in order to maximize their utilization and enhance the quality of health care in such settings.

In a developing country with limited resources, it is important to utilize the total cost visibility approach over the entire life-cycle of the technology and then analyse alternative options for acquiring technology. The present study analysed cost-effectiveness of an "In-house" magnetic resonance imaging (MRI) scan facility of a large service hospital against outsourcing possibilities. Cost per unit scan was calculated by operating costing method and break-even volume was calculated. Then life-cycle cost analysis was performed to enable total cost visibility of the MRI scan in both "In-house" and "outsourcing of facility" configuration. Finally, cost-effectiveness analysis was performed to identify the more acceptable decision option. Total cost for performing unit MRI scan was found to be Rs 3,875 for scans without contrast and Rs 4,129 with contrast. On life-cycle cost analysis, net present value (NPV) of the "In-house" configuration was found to be Rs-(4,09,06,265) while that of "outsourcing of facility" configuration was Rs-(5,70,23,315). Subsequently, cost-effectiveness analysis across eight Figures of Merit showed the "In-house" facility to be the more acceptable option for the system. Every decision for acquiring high-end technology must be subjected to life-cycle cost analysis.

Objectives. We determined the impact of obtaining housing on geriatric conditions and acute care utilization among older homeless adults. Methods. We conducted a 12-month prospective cohort study of 250 older homeless adults recruited from shelters in Boston, Massachusetts, between January and June 2010. We determined housing status at follow-up, determined number of emergency department visits and hospitalizations over 12 months, and examined 4 measures of geriatric conditions at baseline and 12 months. Using multivariable regression models, we evaluated the association between obtaining housing and our outcomes of interest. Results. At 12-month follow-up, 41% of participants had obtained housing. Compared with participants who remained homeless, those with housing had fewer depressive symptoms. Other measures of health status did not differ by housing status. Participants who obtained housing had a lower rate of acute care use, with an adjusted annualized rate of acute care visits of 2.5 per year among participants who obtained housing and 5.3 per year among participants who remained homeless. Conclusions. Older homeless adults who obtained housing experienced improved depressive symptoms and reduced acute care utilization compared with those who remained homeless. PMID:25973822

Homelessness affects HIV risk and health, but little is known about the longitudinal effects of rental assistance on the housing status and health of homeless and unstably housed people living with HIV/AIDS. Homeless/unstably housed people living with HIV/AIDS (N = 630) were randomly assigned to immediate Housing Opportunities for People with AIDS (HOPWA) rental assistance or customary care. Self-reported data, CD4, and HIV viral load were collected at baseline, 6, 12, and 18 months. Results showed that housing status improved in both groups, with greater improvement occurring in the treatment group. At 18 months, 51% of the comparison group had their own housing, limiting statistical power. Intent-to-treat analyses demonstrated significant reductions in medical care utilization and improvements in self-reported physical and mental health; significant differential change benefiting the treatment group was observed for depression and perceived stress. Significant differences between homeless and stably housed participants were found in as-treated analyses for health care utilization, mental health, and physical health. HOPWA rental assistance improves housing status and, in some cases, health outcomes of homeless and unstably housed people living with HIV/AIDS.

Full Text Available Abstract Background British government policy for older people focuses on a vision of active ageing and independent living. In the face of diminishing personal capacities, the use of appropriate home-based technology (HBT devices could potentially meet a wide range of needs and consequently improve many aspects of older people's quality of life such as physical health, psychosocial well-being, social relationships, and their physical or living environment. This study aimed to examine the use of HBT devices and the correlation between use of such devices and quality of life among older people living in extra-care housing (ECH. Methods A structured questionnaire was administered for this study. Using purposive sampling 160 older people living in extra-care housing schemes were selected from 23 schemes in England. A face-to-face interview was conducted in each participant's living unit. In order to measure quality of life, the SEIQoL-Adapted and CASP-19 were used. Results Although most basic appliances and emergency call systems were used in the living units, communally provided facilities such as personal computers, washing machines, and assisted bathing equipment in the schemes were not well utilised. Multiple regression analysis adjusted for confounders including age, sex, marital status, living arrangement and mobility use indicated a coefficient of 1.17 with 95% CI (0.05, 2.29 and p = 0.04 [SEIQoL-Adapted] and 2.83 with 95% CI (1.17, 4.50 and p = 0.001 [CASP-19]. Conclusions The findings of the present study will be value to those who are developing new form of specialised housing for older people with functional limitations and, in particular, guiding investments in technological aids.

The combination of distributed energy resources (DER) and retail tariff structures to provide benefits to both utility consumers and the utilities is not well understood. To improve understanding, an Integrated Energy System Model (IESM) is being developed to simulate the physical and economic aspects of DER technologies, the buildings where they reside, and feeders servicing them. The IESM was used to simulate 20 houses with home energy management systems on a single feeder under a time-of-use (TOU) tariff to estimate economic and physical impacts on both the households and the distribution utilities. Home energy management systems (HEMS) reduce consumers’ electric bills by precooling houses in the hours before peak electricity pricing. Utilization of HEMS reduce peak loads during high price hours but shifts it to hours with off-peak and shoulder prices, resulting in a higher peak load. used to simulate 20 houses with home energy management systems on a single feeder under a time-of-use (TOU) tariff to estimate economic and physical impacts on both the households and the distribution utilities.

Full Text Available Based on numerical simulations, the heating load reduction effect of an attached sunspace in winter was determined, and the effective heat utilization method and sunspace design were explored. In this paper, we studied the heating load reduction effect using heat from the sunspace and temperature fluctuation of each room at the time of heat use from the sunspace (sending air from the sunspace to the heating, ventilation, and air conditioning (HVAC machine room and taking the air to the adjacent rooms. In the case of the all-day HVAC system, it was confirmed that a larger capacity of sunspace and not sending air from the sunspace to the adjacent room demonstrated a better heating-load reduction effect. Compared with Model Iw (a house with a window on the exterior of the sunspace opened to external air, Model I (a house with an attached sunspace on the second floor could save approximately 41% of the total energy. Model II (a house with the attached sunspace both on the first and second floors could save approximately 84% of the total energy. Sending heat from the sunspace to the adjacent room led to temperature increases in the adjacent rooms. However, if the construction plan is to have the sunspace only on the second floor, the house should be carefully designed, for example, by placing a living room on the second floor.

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

The overall objective of the Advanced Turbine System (ATS) Phase 3 Cooperative Agreement between GE and the US Department of Energy (DOE) is the development of a highly efficient, environmentally superior, and cost-competitive utility ATS for base-load utility-scale power generation, the GE 7H (60 Hz) combined cycle power system, and related 9H (50 Hz) common technology. The major effort will be expended on detail design. Validation of critical components and technologies will be performed, including: hot gas path component testing, sub-scale compressor testing, steam purity test trials, and rotational heat transfer confirmation testing. Processes will be developed to support the manufacture of the first system, which was to have been sited and operated in Phase 4 but will now be sited and operated commercially by GE. This change has resulted from DOE's request to GE for deletion of Phase 4 in favor of a restructured Phase 3 (as Phase 3R) to include full speed, no load (FSNL) testing of the 7H gas turbine. Technology enhancements that are not required for the first machine design but will be critical for future ATS advances in performance, reliability, and costs will be initiated. Long-term tests of materials to confirm design life predictions will continue. A schematic of the GE H machine is shown.

Full Text Available Subject: smart house maintenance requires taking into account a number of factors: resource-saving, reduction of operational expenditures, safety enhancement, providing comfortable working and leisure conditions. Automation of the corresponding engineering systems of illumination, climate control, security as well as communication systems and networks via utilization of contemporary technologies (e.g., IoT - Internet of Things poses a significant challenge related to storage and processing of the overwhelmingly massive volume of data whose utilization extent is extremely low nowadays. Since a building’s lifespan is large enough and exceeds the lifespan of codes and standards that take into account the requirements of safety, comfort, energy saving, etc., it is necessary to consider management aspects in the context of rational use of large data at the stage of information modeling. Research objectives: increase the efficiency of managing the subsystems of smart buildings hardware on the basis of a web-based information system that has a flexible multi-level architecture with several control loops and an adaptation model. Materials and methods: since a smart house belongs to man-machine systems, the cybernetic approach is considered as the basic method for design and research of information management system. Instrumental research methods are represented by set-theoretical modelling, automata theory and architectural principles of organization of information management systems. Results: a flexible architecture of information system for management of smart house hardware subsystems has been synthesized. This architecture encompasses several levels: client level, application level and data level as well as three layers: presentation level, actuating device layer and analytics layer. The problem of growing volumes of information processed by realtime message controller is attended by employment of sensors and actuating mechanisms with configurable

The transfer of technologies for biomass energy utilization

Schneiders, H.H.

1995-01-01

The first part of the paper presents the common perception of technology transfer as a trade relationship rather than a systematic approach to establish a complex technological capacity in a given field. It aims to correct this misperception by introducing some other ideas: (a) the need to support the people, adjust the relevant organizations and establish the capacities to provide the products and services; (b) the typical life cycles of technologies from the initial concept to the final stages of transfer and sustainable dissemination; (c) the needs and expectations of the groups targeted by the technologies for biomass energy utilization. The second part of the paper discusses one example of successful technology transfer: the use of large biomass-burning stoves for food preparation in public institutions and private restaurants in East Africa. The third part of the paper highlights two non-technological barriers to the transfer of biomass energy technologies: (a) weak market forces and business interests and a large number of State activities and projects and (b) conflicting interests of end-users, craftsmen, private and public project partners, which can threaten the success of the attempted technology transfer, even after local adaptation. Finally, suggestions are made for overcoming some of these problems. (author)

Introduction Image sharing technologies may reduce unneeded imaging by improving provider access to imaging information. A systematic review and meta-analysis were conducted to summarize the impact of image sharing technologies on patient imaging utilization. Methods Quantitative evaluations of the effects of PACS, regional image exchange networks, interoperable electronic heath records, tools for importing physical media, and health information exchange systems on utilization were identified through a systematic review of the published and gray English-language literature (2004–2014). Outcomes, standard effect sizes (ESs), settings, technology, populations, and risk of bias were abstracted from each study. The impact of image sharing technologies was summarized with random-effects meta-analysis and meta-regression models. Results A total of 17 articles were included in the review, with a total of 42 different studies. Image sharing technology was associated with a significant decrease in repeat imaging (pooled effect size [ES] = −0.17; 95% confidence interval [CI] = [−0.25, −0.09]; P utilization (pooled ES = 0.20; 95% CI = [0.07, 0.32]; P = .002). For all outcomes combined, image sharing technology was not associated with utilization. Most studies were at risk for bias. Conclusions Image sharing technology was associated with reductions in repeat and unnecessary imaging, in both the overall literature and the most-rigorous studies. Stronger evidence is needed to further explore the role of specific technologies and their potential impact on various modalities, patient populations, and settings. PMID:26614882

Acquiring energy savings in manufactured housing

International Nuclear Information System (INIS)

Davey, D.

1993-01-01

In 1991, the Northwest utilities faced a complex situation. They needed new sources of electrical power to avoid future deficits. A significant block of energy savings was available in the manufactured housing sector in the form of energy savings from increased insulation to new manufactured homes. The manufacturers were interested in saving the electricity in the homes, but would only deal with the utility sector as a whole. Half of the homes targeted were sited in investor-owned utility (IOU) service territories, and half in the public sector made up of utilities that purchased some or all of their electricity from the Bonneville Power Administration. Utilities agreed to acquire energy from manufacturers In the form of thermal efficiency measures specified by the Bonneville Power Administration. The program that resulted from over one year of negotiations was called the Manufactured Housing Acquisition Program, or MAP. Manufacturers, the utilities, State Energy Offices, the Northwest Power Planning Council and Bonneville all worked closely and with tenacity to build the program that went into effect on April 1, 1992, and should save the region between 7 and 9 megawatts, enough energy to supply 11,000 homes in the Northwest

In this article we examine aspects of the different arguments for the environmental advantages of co-housing compared with individual households. The analysis is structured around four main questions, which are argued to be decisive for the question of co-housing and sustainability. The first...... is whether co-housing offers better opportunities for choosing and using more sustainable technologies, which also relates to the question of whether co-housing offers better opportunities for building smaller and denser and thus more energy efficient buildings. The second and third questions are socially...... oriented; one relates to the claim that co-housing can support pro-environmental behaviour among residents as they can support each other’s norms and practices. The fourth and last claim relates to a discussion of co-housing as a more sustainable opportunity especially for people living alone...

This study assesses factors that utilities must address when they integrate intermittent renewable technologies into their power-supply systems; it also reviews the literature in this area and has a bibliography containing more than 350 listings. Three topics are covered: (1) interface (hardware and design-related interconnection), (2) operability/stability, and (3) planning. This study finds that several commonly held perceptions regarding integration of intermittent renewable energy technologies are not valid. Among fmdings of the study are the following: (1) hardware and system design advances have eliminated most concerns about interface, (2) cost penalties have not occurred at low to moderate penetration levels (and high levels am feasible); and (3) intermittent renewable energy technologies can have capacity values. Obstacles still interfering with intermittent renewable technologies are also indentified.

2011-07-01

Full Text Available The recent decades have witnessed the widespread manifestation of intelligent building design development around the world. Meanwhile, the concept of smart housing as one of the main issues of intelligent building design development has stimulated various architects and designers to make use of it for the sake of sustainable housing. However, this study represents a gap in smart housing design owing to the lack of a deep consideration on cultural values of users for ensuring the socio-cultural sustainability as one of the objectives of sustainable smart housing designs. Accordingly, the study puts forward the concept of local-smart-housing through utilization of appropriate vernacular architectural features and cultural values of vernacular settlements in smart housing design in order to reinforce the sociocultural sustainability. Meanwhile, this study is limited to the Malay context in order to identify the vernacular features of Malay vernacular settlement’s functional spaces for utilization in smart housing design to make them culturally responsive. Correspondingly, this study proposes the concept of local-smart-housing based on the incorporation of intelligent building design and utilization of vernacular features for enhancing the quality of life for users.

Adopting Product Modularity in House Building to Support Mass Customisation

Directory of Open Access Journals (Sweden)

Cecília G. da Rocha

2015-04-01

Full Text Available Product modularity is a concept that can contribute to the improvement of product quality and production efficiency in house-building. However, there is a lack of consensus in the literature on the concepts that define product modularity. Furthermore, little attention has been given to the differences between building construction and manufacturing, for which product modularity was originally developed. This research aims to address that gap by adapting the conceptualization of product modularity so that it can effectively be used in the house-building industry. The methodological approach adopted in this study was Design Science Research, and two empirical studies were carried out on construction companies based in Brazil and in the U.K. Those studies are used to illustrate the applicability and utility of the proposed concepts and tools. Research findings indicate that the adoption of product modularity concepts results in benefits to both traditional construction technologies and pre-fabricated building systems.

Spinoff 2002: Fortieth Anniversary Technology Utilization Program

Science.gov (United States)

2002-01-01

Since its inception 40 years ago, NASA's Technology Transfer Program has led the way for our nation to benefit from cutting-edge aerospace technologies. In addition to contributing to U.S. economic growth, these technologies are improving the quality of life on Earth while finding new ways to protect and preserve it. NASA's research and development efforts have advanced areas in medicine, communications, manufacturing, computer technology, and homeland security. These breakthroughs, translated into commercial products, are enhancing the lives of Americans everywhere. When a congressional mandate led NASA to develop the Scientific and Technical Information (STI) Program, the Agency began a wide dissemination of its research and development results. In doing so, NASA recognized that many of its technologies were transferable to industry for the development of commercial products. As a result, the Technology Utilization Program was born in 1962. The successful program went through several changes over the years, as its philosophy, mission, and goals adapted into the Technology Transfer Program we know today. The program strives to make the latest technologies available to industry as soon as they are developed. Each year, NASA's Spinoff publication showcases new products and services resulting from commercial partnerships between NASA and private industry. In the 2002 issue, the NASA field centers reflect upon the growth that has made these innovations available to the public. The Research and Development section examines past achievements, current successes, and future goals for each of the ten NASA centers. The Commercial Benefits section proudly highlights 51 new spinoff products, including a heart pump for patients needing a heart transplant, as well as an air purifier that destroys anthrax spores. The Technology Transfer and Outreach section describes the outreach achievements and educational successes made possible through the NASA Commercial Technology Network

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.

Utility-Scale Concentrating Solar Power and Photovoltaic Projects: A Technology and Market Overview

Energy Technology Data Exchange (ETDEWEB)

Mendelsohn, M.; Lowder, T.; Canavan, B.

2012-04-01

Over the last several years, solar energy technologies have been, or are in the process of being, deployed at unprecedented levels. A critical recent development, resulting from the massive scale of projects in progress or recently completed, is having the power sold directly to electric utilities. Such 'utility-scale' systems offer the opportunity to deploy solar technologies far faster than the traditional 'behind-the-meter' projects designed to offset retail load. Moreover, these systems have employed significant economies of scale during construction and operation, attracting financial capital, which in turn can reduce the delivered cost of power. This report is a summary of the current U.S. utility-scale solar state-of-the-market and development pipeline. Utility-scale solar energy systems are generally categorized as one of two basic designs: concentrating solar power (CSP) and photovoltaic (PV). CSP systems can be further delineated into four commercially available technologies: parabolic trough, central receiver (CR), parabolic dish, and linear Fresnel reflector. CSP systems can also be categorized as hybrid, which combine a solar-based system (generally parabolic trough, CR, or linear Fresnel) and a fossil fuel energy system to produce electric power or steam.

2016-01-07

It is widely recognised that the quantity and sustainability of new homes in the UK need to increase. However, it is important that sustainable housing is regarded holistically, and not merely in environmental terms, and incorporates elements that enhance the quality of life, health and well-being of its users. This paper focuses on the "soft" features of sustainable housing, that is, the non-technological components of sustainable housing and neighbourhood design that can impact occupants' health and well-being. Aims of the study are to ascertain the relative level of importance that key housing stakeholders attach to these features and to investigate whether the opinions of housing users and housing providers are aligned with regards to their importance. An online survey was carried out to gauge the level of importance that the key stakeholders, such as housing users, local authorities, housing associations, and developers (n = 235), attach to these features. Results revealed that while suitable indoor space was the feature regarded as most important by all stakeholders, there were also a number of disparities in opinion between housing users and housing providers (and among the different types of providers). This implies a scope for initiatives to achieve a better alignment between housing users and providers.

Examination of incentive mechanisms for innovative technologies applicable to utility and nonutility power generators

Innovative technologies, built by either utility or nonutility power generators, have the potential to lower costs with less environmental emissions than conventional technologies. However, the public-good nature of information, along with uncertain costs, performance, and reliability, discourages rapid adoption of these technologies. The effect of regulation of electricity production may also have an adverse impact on motivation to innovate. Slower penetration of cleaner, more efficient technologies could result in greater levels of pollution, higher electricity prices, and a reduction in international competitiveness. Regulatory incentives could encourage adoption and deployment of innovative technologies of all kinds, inducting clean coal technologies. Such incentives must be designed to offset risks inherent in innovative technology and encourage cost-effective behavior. To evaluate innovative and conventional technologies equally, the incremental cost of risk (ICR) of adopting the innovative technology must be determined. Through the ICR, the magnitude of incentive required to make a utility (or nonutility) power generator equally motivated to use either conventional or innovative technologies can be derived. Two technology risks are examined: A construction risk, represented by a 15% cost overrun, and an operating risk, represented by a increased forced outage rate (decreased capacity factor). Different incentive mechanisms and measurement criteria are used to assess the effects of these risks on ratepayers and shareholders. In most cases, a regulatory incentive could offset the perceived risks while encouraging cost-effective behavior by both utility and nonutility power generators. Not only would the required incentive be recouped, but the revenue requirements would be less for the innovative technology; also, less environmental pollution would be generated. In the long term, ratepayers and society would benefit from innovative technologies.

Praeve, P

1977-01-01

Until recently microbiology had found use only in the foodstuffs sector and in the production of antibiotics; however, the production of biomass should be regarded as the key development of the new science of biotechnology. The biomass consists of fatty and protein-rich microorganisms that can be used for example, in animal feeds. The microorganisms grow not only on cellulose waste and other biological substrates but also, for example, on petroleum and methanol. Their energy demand is comparatively low. It is being realized more and more that inflexible technologies pose problems for our civilization and that biotechnology, which utilizes the cyclic metabolic pathways of microorganisms and often recycles waste materials, shows great promise for the future. Equipment used in the single-cell protein technology is briefly described.

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

With these funds, HCD builds 80 to 100 new houses and renovates about 500 homes each year. Houses constructed or renovated by HCD must meet HUD`s minimum energy efficiency standards. While these minimum standards are more than adequate to meet local building codes, they are not as aggressive as the energy efficiency standards being promoted by the national utility organizations and the home building industry. Memphis Light, Gas and Water (MLGW), a city-owned utility, has developed an award-winning program named Comfort Plus which promotes energy efficiency{open_quote} in new residential construction. Under Comfort Plus, MLGW models house plans on computer for a fee and recommends cost-effective alterations which improve the energy efficiency of the house. If the builder agrees to include these recommendations, MLGW will certify the house and guarantee a maximum annual heating/cooling bill for two years. While the Comfort Plus program has received recognition in the new construction market, it does not address the existing housing stock.

The overall objective of the Advanced Turbine System (ATS) Phase 3 Cooperative Agreement between GE and the U.S. Department of Energy (DOE) is the development of a highly efficient, environmentally superior, and cost-competitive utility ATS for base-load utility-scale power generation, the GE 7H (60 Hz) combined cycle power system, and related 9H (50 Hz) common technology. The major effort will be expended on detail design. Validation of critical components and technologies will be performed, including: hot gas path component testing, sub-scale compressor testing, steam purity test trials, and rotational heat transfer confirmation testing. Processes will be developed to support the manufacture of the first system, which was to have been sited and operated in Phase 4 but will now be sited and operated commercially by GE. This change has resulted from DOE's request to GE for deletion of Phase 4 in favor of a restructured Phase 3 (as Phase 3R) to include full speed, no load (FSNL) testing of the 7H gas turbine. Technology enhancements that are not required for the first machine design but will be critical for future ATS advances in performance, reliability, and costs will be initiated. Long-term tests of materials to confirm design life predictions will continue. A schematic of the GE H machine is shown in Figure 1-1. Information specifically related to 9H production is presented for continuity in H program reporting, but lies outside the ATS program. This report summarizes work accomplished from 4Q98 through 3Q99. The most significant accomplishments are listed.

Riffat, S.B.; Wilson, R.; Omer, S. [University of Nottingham (United Kingdom). School of the Built Environment

2000-07-01

The aim of this project was to monitor performance of PV systems on the Renewable Energy Centre and the Eco-Energy House at the School of Built Environment, University of Nottingham. The Renewable Energy Centre was constructed using a cash donation from Beacon Energy Limited, while construction of the Eco-Energy House was funded by David Wilson Homes Ltd. The primary role of these facilities is to assist in renewable energy technology transfer. Both buildings were designed to be thermally efficient and utilize a range of renewable energy systems. They will be used to attract and educate visitors from local government, schools and collages, and the general public. This report documents the design process for Building Integrated Photovoltaic (BIPV) systems on the two buildings. The buildings are significantly different in both construction and occupancy but are sited close to each other and share similar weather conditions. The rationale behind the BIPV designs is explained and detail is provided on the final solutions for each building. A number of methods were used to assist in the selection of appropriate PV systems to integrate into each building. These included energy analysis using PVSYST3 software, CAD modelling for aesthetics assessment, architectural and construction considerations and economic justification. The design chosen for Renewable Energy Centre was a vertical wall PV facade system using thin film technology, while a roof integrated system using monocrystalline PV roofing slates was chosen for the Eco-Energy House. In terms of economic justification, both systems cannot be said to be cost effective at the current market price for energy, however, the aim was to bring the technology to the attention of a wide audience and demonstrate the potential of the systems for reducing CO{sub 2} emission to the environment.

A technology-assessment methodology for electric utility planning: With application to nuclear power plant decommissioning

International Nuclear Information System (INIS)

Lough, W.T.

1987-01-01

Electric utilities and public service commissions have not taken full advantage of the many proven methodologies and techniques available for evaluating complex technological issues. In addition, evaluations performed are deficient in their use of (1) methods for evaluating public attitudes and (2) formal methods of analysis for decision making. These oversight are substantiated through an examination of the literature relevant to electric utility planning. The assessment process known as technology assessment or TA is proposed, and a TA model is developed for route in use in utility planning by electric utilities and state regulatory commissions. Techniques to facilitate public participation and techniques to aid decision making are integral to the proposed model and are described in detail. Criteria are provided for selecting an appropriate technique on a case-by-case basis. The TA model proved to be an effective methodology for evaluating technological issues associated with electric utility planning such as decommissioning nuclear power plants. Through the use of the nominal group technique, the attitudes of a group of residential ratepayers were successfully identified and included in the decision-making process

Several improvements of irradiation capsule technology regarding irradiation test parameters, such as temperature and neutron flux/fluence, and regarding instrumentation have progressed at HANARO since the last KAERI-JAERI joint seminar held in 2008. The standard HANARO capsule technology that was developed for use in a commercial power plant temperature of about 300degC was improved to apply to a temperature range of 100-1000degC for the irradiation test of materials of new research reactors and future nuclear systems. Low-flux and long-term irradiation technologies have been developed at HANARO. As a beginning step of the localization of capsule instrumentation technology, the irradiation performance of a domestically produced thermocouple and LVDT will be examined at HANARO. The accuracy of an evaluation of neutron fluence and precise welding technology are also being examined at HANARO. Based on these accumulated capsule technologies, a HANARO irradiation capsule system is being actively utilized for the national R and D programme on commercial nuclear reactors and nuclear fuel cycle technology in Korea. HANARO has recently started the irradiation support of R and D relevant to future nuclear systems including SMART, VHTR, and SFR, and HANARO is preparing new support relevant to new research and Fusion reactors.

  This paper examines the historical background, current context and future challenges for housing energy consumption in Denmark. There has been a radical transformation in housing energy consumption over the last 30 years, with an absolute reduction in heat consumption and a rapid growth...... in electricity consumption, reflecting wider technological and social transformations in the movement from an industrial to a knowledge based society. In new housing it is shown that electricity consumption now dominates the total primary energy consumption, and that as a consequence traditional heat saving...... paradigms are relatively less effective, and can result in overheating and rising electricity consumption. At the same time, climate change concerns show that rising temperatures will in the future result in a falling heat demand and increasing cooling demand in housing.

Prochorskaite, Agne; Couch, Chris; Malys, Naglis; Maliene, Vida

2016-01-01

It is widely recognised that the quantity and sustainability of new homes in the UK need to increase. However, it is important that sustainable housing is regarded holistically, and not merely in environmental terms, and incorporates elements that enhance the quality of life, health and well-being of its users. This paper focuses on the “soft” features of sustainable housing, that is, the non-technological components of sustainable housing and neighbourhood design that can impact occupants’ health and well-being. Aims of the study are to ascertain the relative level of importance that key housing stakeholders attach to these features and to investigate whether the opinions of housing users and housing providers are aligned with regards to their importance. An online survey was carried out to gauge the level of importance that the key stakeholders, such as housing users, local authorities, housing associations, and developers (n = 235), attach to these features. Results revealed that while suitable indoor space was the feature regarded as most important by all stakeholders, there were also a number of disparities in opinion between housing users and housing providers (and among the different types of providers). This implies a scope for initiatives to achieve a better alignment between housing users and providers. PMID:26751465

Advanced Acid Gas Separation Technology for the Utilization of Low Rank Coals

Energy Technology Data Exchange (ETDEWEB)

Kloosterman, Jeff

2012-12-31

Air Products has developed a potentially ground-breaking technology – Sour Pressure Swing Adsorption (PSA) – to replace the solvent-based acid gas removal (AGR) systems currently employed to separate sulfur containing species, along with CO{sub 2} and other impurities, from gasifier syngas streams. The Sour PSA technology is based on adsorption processes that utilize pressure swing or temperature swing regeneration methods. Sour PSA technology has already been shown with higher rank coals to provide a significant reduction in the cost of CO{sub 2} capture for power generation, which should translate to a reduction in cost of electricity (COE), compared to baseline CO{sub 2} capture plant design. The objective of this project is to test the performance and capability of the adsorbents in handling tar and other impurities using a gaseous mixture generated from the gasification of lower rank, lignite coal. The results of this testing are used to generate a high-level pilot process design, and to prepare a techno-economic assessment evaluating the applicability of the technology to plants utilizing these coals.

The objective of this study was to determine the effect of house cricket (Acheta domesticus) flour addition on physicochemical and textural properties of meat emulsion under various formulations. As an initial marker of functionality, protein solubility, water absorption, emulsifying capacity, and gel formation ability of house cricket flour were determined at pH (2 to 10) and NaCl concentrations (0 to 2.10 M). Control emulsion was formulated with 60% lean pork, 20% back fat, and 20% ice. Six treatment emulsions were prepared with replacement of lean pork and/or back fat portions with spray-dried house cricket flour at 5% and 10% levels, based on a total sample weight. The protein solubility of house cricket flour (67 g protein/100 g) was significantly altered depending upon pH (P house cricket flour were found between 0 and 2.10 M NaCl concentration (P > 0.05). The replacement of lean meat/fat portion with house cricket flour within 10% level could fortify protein and some micronutrients (phosphorus, potassium, and magnesium) in meat emulsion, without negative impacts on cooking yield and textural properties. Our results suggest that house cricket flour can be used as an effective nonmeat functional ingredient to manufacture emulsified meat products. To better utilize house cricket flour as a food ingredient in wide application, understanding its technological properties in various pH, and ionic strength conditions is a pivotal step. Protein solubility of house cricket flour would be considerably affected by the varying pH and NaCl concentrations of applied conventional foods. In the case of meat emulsion, within 10% lean meat and/or fat portions could be successfully substituted with house cricket flour without detectable adverse impacts on technological properties associated with cooking yield and instrumental analysis of texture. Thus, our findings suggest that house cricket flour possess the necessary physical properties to be used as an alternative nonmeat

Technology-based applications represent a promising method for providing efficacious, widely available interventions to substance abuse treatment patients. However, limited access to communication technology (i.e., mobile phones, computers, internet, and e-mail) could significantly impact the feasibility of these efforts, and little is known regarding technology utilization in substance abusing populations. A survey was conducted to characterize utilization of communication technology in 266 urban, substance abuse treatment patients enrolled at eight drug-free, psychosocial or opioid-replacement therapy clinics. Survey participants averaged 41 years of age and 57% had a yearly household income of less than $15,000. The vast majority reported access to a mobile phone (91%), and to SMS text messaging (79%). Keeping a consistent mobile phone number and yearly mobile contract was higher for White participants, and also for those with higher education, and enrolled in drug-free, psychosocial treatment. Internet, e-mail, and computer use was much lower (39-45%), with younger age, higher education and income predicting greater use. No such differences existed for the use of mobile phones however. Concern regarding the digital divide for marginalized populations appears to be disappearing with respect to mobile phones, but still exists for computer, internet, and e-mail access and use. Results suggest that mobile phone and texting applications may be feasibly applied for use in program-client interactions in substance abuse treatment. Careful consideration should be given to frequent phone number changes, access to technology, and motivation to engage with communication technology for treatment purposes.

A three-dimensional model for technology pricing is proposed and The TOPSPS algorithm has been utilized to select the most similar technologies to the intended one and the constructed scoring system is applied to calculate the final technology price accordingly.

Reduction of carbon dioxide emissions by solar water heating systems and passive technologies in social housing

International Nuclear Information System (INIS)

Bessa, Vanessa M.T.; Prado, Racine T.A.

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

Within constructional technology prefabricated house is known as a house whose most of the components like walls, roofs, toilets, and structural cubes and columns are designated and produced in factory and assembled in site. Based on the experience in certain countries, prefabricated house has successfully entered commercial market. Prefabricated house shows a better infestation value than conventional houses. With prefabrication technology, building construction could be done faster and cost lower price, along with a good craftsmanship quality. Until now, Indonesia is still facing settlements issues and one of them is housing backlog whose amount revolves around 13 Million units. Prefabricated houses potentially solve the settlement issue in Indonesia in a much faster way. Yet the development of prefabricated house has not been accepted well in the market yet, both by the producers and the consumers. This writing talks about the result of the research about the causes of the lack of development in Indonesia when it comes to prefabricated houses though the method of comparison; comparing prefabricated house with conventional house when it comes to its 1) productivity rate, 2) consumers preference and 3) infestation performance. The data is collected through survey methods, interview and questionnaires. The result shows that even though the productivity rate when it comes to quality and time is high, prefabricated house shows low productivity when it comes to cost because it requires greater cost than it is in conventional houses. Other than that, the lack of business development when it comes to prefabricated houses is caused by the low preference of consumers toward the product- because of its inflexibility and monotonous appearance. The infestation of prefabricated house development shows a low NPV and IRR. With a more proper infestation approach such as mass constructions with effective numbers, good flexibility, and various appearances, prefabricated house

Therefore, further exploration and investigation on this technology are needed. There are two key points in the bio-cleaning technology in SPF chicken production. The first one is to purify the air by using advanced barrier facilities so as to blocking all pathogenic microorganisms from entering into the SPF chicken bio-cleaning room. The second one is to apply strict management measures to prevent the bacteria and viruses that carried by human from entering into the SPF chicken house, and to eliminate the missing or remaining bacteria and viruses in cleanroom by disinfection and sterilization. In this paper, the technology for purification management of SPF chicken house is introduced, so as to provide theoretical basis for the improvement of the purification quality of SPF chickens.

Tomorrow's house: solar housing in 1940s America.

Science.gov (United States)

Barber, Daniel A

2014-01-01

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.

Low hanging fruit? Regulations and energy efficiency in subsidized multifamily housing

International Nuclear Information System (INIS)

Reina, Vincent J.; Kontokosta, Constantine

2017-01-01

The U.S. government has invested in multifamily housing through an array of subsidized housing programs. These programs provide a venue for understanding how regulations governing multifamily housing can affect an owner's incentive to make energy efficient investments, and a tenant's desire to reduce their energy consumption levels. This paper empirically tests the impact of subsidized housing regulations on the energy efficiency of multi-family housing for low-income households. We begin by constructing a unique database that integrates actual energy use with physical, socioeconomic, and regulatory characteristics of all large multifamily properties in New York City, focusing on whether a property receives a federal rental subsidy. We employ multivariate regression models to examine the factors that influence energy consumption in multi-family buildings and compare subsidized housing to market-rate housing, controlling for a range of building and household characteristics. We find that subsidized properties are associated with higher energy consumption than similar market-rate properties and, of the subsidized housing programs, Public Housing tends to consume the most energy. Our results suggest that despite the potential for retrofitting multifamily properties, and associated cost, energy, and carbon emissions savings, regulatory factors constrain investment and consumption decisions in the case of subsidized properties. Reducing energy use in subsidized housing, therefore, rests on modifying existing regulations. - Highlights: • Developed a framework for why regulations affect utility consumption incentives. • Created and employed a dataset of actual energy use for all large properties in NYC. • Found that subsidized properties are associated with higher utility consumption. • Find that Public Housing tends to consume the most energy of the subsidy programs. • Find that regulatory factors affect investment and consumption decisions.

Optimal Housing, Consumption, and Investment Decisions over the Life Cycle

DEFF Research Database (Denmark)

Kraft, Holger; Munk, Claus

2011-01-01

We derive explicit solutions to life-cycle utility maximization problems involving stock and bond investment, perishable consumption, and the rental and ownership of residential real estate. Prices of houses, stocks and bonds, and labor income are correlated. Because of a positive correlation...... between house prices and labor income, young individuals want little exposure to house price risk and tend to rent their home. Later in life the desired housing investment increases and will eventually reach and exceed the desired consumption, suggesting that the individual should buy his home—and either...... additional housing units (for renting out) or house price–linked financial assets. In the final years, preferences shift back to home rental. The derived strategies are still useful if housing positions are only reset infrequently. Our results suggest that markets for real estate investment trusts or other...

Mobile integrated temporary utility system. Innovative technology summary report

International Nuclear Information System (INIS)

1998-12-01

The Mobile Integrated Temporary Utility System (MITUS) integrates portable electrical power along with communications and emergency alarm and lighting capabilities to provide safe, centralized power to work areas that need to be de-energized for decommissioning work. MITUS consists of a portable unit substation; up to twenty portable kiosks that house the power receptacles, communications, and emergency alarm and lighting systems; and a central communications unit. This system makes sequential decommissioning efforts efficient and cost-effective by allowing the integrated system to remain intact while being moved to subsequent work sites. Use of the MITUS also eliminates the need to conduct zero-energy tests and implement associated lock-out/tag-out procedures at partially de-energized facilities. Since the MITUS is a designed system, it can be customized to accommodate unique facility conditions simply by varying kiosks and transformer configurations. The MITUS is an attractive alternate to the use of portable generators with stand-alone communications and emergency system. It is more cost-effective than upgrading or reconfiguring existing power distribution systems

The role of exergy in increasing utilization of green energy and technologies. Paper no. IGEC-1-Keynote-Rosen

Rosen, M.A.

2005-01-01

The use of exergy is described as a measure for identifying and explaining the benefits of green energy and technologies, so the benefits can be clearly understood and appreciated by experts and non-experts alike, and the utilization of green energy and technologies can be increased. Exergy can be used to assess and improve energy systems, and can help better understand the benefits of utilizing green energy by providing more useful and meaningful information than energy provides. Exergy clearly identifies efficiency improvements and reductions in thermodynamic losses attributable to green technologies. Exergy can also identify better than energy the environmental benefits and economics of energy technologies. Exergy should be utilized to engineers and scientists, as well as decision and policy makers, involved in green energy and technologies. (author)

Rosenthal, David A; Layman, Elizabeth J

2008-02-13

The United States Department of Health and Human Services (DHHS) has emphasized the importance of utilizing health information technologies, thus making the availability of electronic resources critical for physicians across the country. However, few empirical assessments exist regarding the current status of computerization and utilization of electronic resources in physician offices and physicians' perceptions of the advantages and disadvantages of computerization. Through a survey of physicians' utilization and perceptions of health information technology, this study found that a "digital divide" existed for eastern North Carolina physicians in smaller physician practices. The physicians in smaller practices were less likely to utilize or be interested in utilizing electronic health records, word processing applications, and the Internet.

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.

2004-01-01

The blackout of August 14, 2003 is used as the incentive to examine transmission grid reliability, expose its deficiencies in terms of technology, standards and processes used to manage reliability, and to make recommendations for leveraging existing resources and upgrading both the technology and procedures to avoid similar breakdowns in the future. It is recommended that in the area of monitoring transmission grid reliability utilities should borrow a page from the Enterprise Risk Management Practices of the financial industry by adopting a system which looks beyond the first 'credible' contingency (the current system) and examine many more 'incredible' contingencies, and underlying events that can trigger multiple contingencies, and plan for them in their operations. Utility companies are also urged to upgrade their energy management systems (EMS) technology to be able to deal with the kinds of severely depressed voltages and overloaded circuits that many grids experience today. Investment in new capabilities in control rooms, more and better communications will be essential. EMS algorithms and models must be upgraded to operate under a broader spectrum of grid conditions and to simulate the once-in-a-lifetime outage scenarios that most operators believe could never strike their utility. Expert opinion strongly suggests that as part of this process of upgrading, contingency analysis should shift from the 'N-1' model of the present to a stochastic model that considers a wider range of possible events in a probabilistic framework

2000-02-23

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

Full Text Available The study focused on the extent of utilization of the educational innovations and technology in research and extension functions of SUs. The descriptive design, triangulation method, and purposive sampling were applied in this study. The findings revealed that majority of the respondents are married adults and master’s degree graduates with education as their area of specialization. They are permanent in status and have considerable years in the University serving as research or extension officer. Research of SUs have common research thrusts in terms of environment and natural resources management but differ in their own respective agenda; similarly the SUs share common extension thrusts and concerns but differ in their programs, activities and projects related to community services. Commonly encountered problems concern inadequate funds and inability to access the available technology. Officers utilized educational innovations on research and extension to a moderate extent but software and hardware were utilized to a great extent; likewise internet-based communication was utilized to a great extent for research but used moderately for extension. This implies that compared to research, most of the extension functions do not require the use of internet-based communication. From the results of the study, it was recommended that review of the existing allocation of funds for technology development may be done to improve the existing hardware, software and communication facilities.

Inuit children in Alaska and Nunavut have high rates of severe lower respiratory tract infections, with hospitalization rates of 300 per year for each 1000 infants. The aim of this research report was to summarize the findings of a pilot project measuring the indoor air quality (IAQ) in 20 Cape Dorset houses as well as a study measuring the ventilation rates of 100 house from 4 communities in Nunavut. The 20 house pilot study included a respiratory questionnaire; a detailed home inspection and data collection; a blower door airtightness test; 7 day measurements of nitrogen dioxide (NO{sub 2}), nicotine, carbon dioxide (CO{sub 2}), relative humidity and temperature; a natural air change rate testing using Brookhaven tracer gas technology; and settled floor dust and bed dust collection followed by biological analysis. The 100 house study recorded 3 to 5 days of house temperatures, relative humidity and CO{sub 2}. The Brookhaven tracer gas technique was used to establish house air change rate. A questionnaire was used to assess ventilation devices. A medical questionnaire was administered and an evaluation of hospitalization data was carried out. Results indicated that a large number of Nunavut houses were not adequately ventilated. In the 20 house study, a third of the houses showed air change rates that would be considered low by any ventilation standards, and that were very low when considering the high occupancy of the houses. In the hundred house study, almost all houses indicated a mean CO{sub 2} level over 1000 ppm, and peaks exceeded 2000 ppm in approximately half the houses. The concentrations were far higher than those seen in southern Canadian homes. It was concluded that the development and promotion of energy-efficient ventilation devices could help to resolve ventilation deficiencies in Nunavut. 2 figs.

2017-02-01

Housing instability threatens the health and well-being of millions of families across the United States, yet little is known about the characteristics or housing trajectories of at-risk families. To address this gap in our understanding of family risk for housing instability and homelessness, we undertook a qualitative descriptive study utilizing a convenience sample of 16 mothers recruited from a housing service agency living in Detroit and receiving emergency services to avoid homelessness. Participants completed the Brief Patient Health Questionnaire (PHQ), then narrated their life events and reasons for housing instability and disclosed desired interventions for homelessness prevention. Data analysis reveals that women experienced high rates of previously undisclosed trauma, broken family relationships, early parenting responsibilities, social isolation, and system failures that contributed to recurrent episodes of housing instability. We argue that housing instability is a symptom of multiple chronic underlying issues that need more than a temporary financial patch.

More than 1 million HUD-supported public housing units provide rental housing for eligible low-income families across the country. A survey of over 100 public housing authorities (PHAs) across the country indicated that there is a high level of interest in developing low-cost solutions that improve energy efficiency and can be seamlessly included in the refurbishment process. Further, PHAs, have incentives (both internal and external) to reduce utility bills. ARIES worked with two PHAs to develop packages of energy efficiency retrofit measures the PHAs can cost effectively implement with their own staffs in the normal course of housing operations when units are refurbished between occupancies. The energy efficiency turnover protocols emphasized air infiltration reduction, duct sealing and measures that improve equipment efficiency. ARIES documented implementation 10 ten housing units. Total source energy consumption savings was estimated at 6%-10% based on BEopt modeling with a simple payback of 1.7 to 2.2 years. At typical housing unit turnover rates, these measures could impact hundreds of thousands of units per year nationally.

Reactor waste heat utilization and district heating reactors. Nuclear district heating in Sweden - Regional reject heat utilization schemes and small heat-only reactors

International Nuclear Information System (INIS)

Hannerz, K.; Larsson, Y.; Margen, P.

1977-01-01

A brief review is given of the current status of district heating in Sweden. In future, district heating schemes will become increasingly interesting as a means of utilizing heat from nuclear reactors. Present recommendations in Sweden are that large reactors should not be located closer than about 20 km from large population centres. Reject heat from such reactors is cheap at source. To minimize the cost of long distance hot water transmission large heat rates must be transmitted. Only areas with large populations can meet this requirement. The three areas of main interest are Malmoe/Lund/Helsingborg housing close to 0.5 million; Greater Stockholm housing 1 to 1.5 million and Greater Gothenburg housing about 0.5 million people. There is an active proposal that the Malmoe/Lund/Helsingborg region would be served by a third nuclear unit at Barsebaeck, located about 20 km from Malmoe/Lund and supplying 950 MW of base load heat. Preliminary proposals for Stockholm involve a 2000 MW heat supply; proposals for Gothenburg are more tentative. The paper describes progress on these proposals and their technology. It also outlines technology under development to increase the economic range of large scale heat transport and to make distribution economic even for low heat-density family housing estates. Regions apart from the few major urban areas mentioned above require the adoption of a different approach. To this end the development of a small, simple low-temperature reactor for heat-only production suitable for urban location has been started in Sweden in close contact with Finland. Some results of the work in progress are presented, with emphasis on the safety requirements. An outline is given in the paper as to how problems of regional heat planning and institutional and legislative issues are being approached

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

Sources of radioactive contamination inside houses

International Nuclear Information System (INIS)

Sajet, A.S.

2010-01-01

People may be exposed at home to multiple sources of nuclear radiation such as gamma, beta and alpha rays emitters. House atmosphere is polluted with nuclear radiation from water pollutants and rocks used in the construction. Radon is the only radioactive non-metallic element. Environmental organizations estimated that all houses contain varying concentrations of radon gas, and the residents are exposed to levels of radon over the years. The source of radon in houses is uranium, which may be found in rocks of the house, soil of the garden, water of the deep artesian wells and building materials, especially granite rocks. Breathing air that contains high levels of radon causes lung cancer. Radon is the second cause of lung disease after smoking. There are many means to reduce house pollution including: utilisation of air filters to remove contaminated dust particles, keep residential areas away from the establishments that use nuclear technology or embedded by nuclear waste, avoid using materials made from asbestos in construction works and proper use and disposal of chemicals and medicines containing radioactive isotopes.

Pak, Chan-Gi

2013-01-01

Modern aircraft employ a significant fraction of their weight in composite materials to reduce weight and improve performance. Aircraft aeroservoelastic models are typically characterized by significant levels of model parameter uncertainty due to the composite manufacturing process. Small modeling errors in the finite element model will eventually induce errors in the structural flexibility and mass, thus propagating into unpredictable errors in the unsteady aerodynamics and the control law design. One of the primary objectives of Multi Utility Technology Test-bed (MUTT) aircraft is the flight demonstration of active flutter suppression, and therefore in this study, the identification of the primary and secondary modes for the structural model tuning based on the flutter analysis of MUTT aircraft. The ground vibration test-validated structural dynamic finite element model of the MUTT aircraft is created in this study. The structural dynamic finite element model of MUTT aircraft is improved using the in-house Multi-disciplinary Design, Analysis, and Optimization tool. In this study, two different weight configurations of MUTT aircraft have been improved simultaneously in a single model tuning procedure.

Quantitative surveys and qualitative focus groups were utilized. These revealed that members of the Lana'i community and LCHC staff and board members regularly utilize technology, in the form of smart cell phones, WiFi, and internet texting. This community has integrated technology into their daily lives, even though they live on an isolated island with 3,102 people; however, despite this integration, the electronic health literacy of this population appears insufficient for proper understanding and utilization of TEC, limiting the potential of patient portals or remote monitoring of patient generated data for chronic disease prevention and management without additional education and mentoring. It is therefore in the best interest of the LCHC and other health organizations wishing to implement TEC in a rural community such as Lana'i to include a strong educational component with use of TEC, and perhaps establish a mentor/partnership program for the highly-challenged patient.

In order to investigate the feasibility of the domestic passive reactor development, the analysis and evaluation on the development status, technical characteristics, and the safety and economy for the overseas passive reactors were carried out based on the vendor's information. Also the domestic nuclear technology basis was surveyed. The analysis and evaluation of the development status and technical characteristics were performed mainly for the AP-600 developed by Westing house and the SIR of UKAEA. The new design concepts and system characteristics have been evaluated by utilizing EPRI Utility Requirement Documents and Lahmeyer evaluation criteria. Based on this evaluation the recommendable design concepts in each major system were selected. The feasibility for the domestic passive reactor development has focused on the safety, technology and economy aspects, and on the applicability of the existing domestic technology to the design of the passive reactor. And the development plan for the domestic passive reactor was recommended in a step by step way. (Author)

Application of 'C.A.R.B. financial methodology' analysis for alternative energy technologies into UK housing

International Nuclear Information System (INIS)

Spanos, Ioannis; Duckers, Les; Holmes, Kenneth L.

2007-01-01

Current energy trends in UK housing are reviewed and then assessed by introducing the 'CARB financial analysis' methodology. CARB is an acronym for 'Carbon Abatement', as it evaluates the potential carbon-dioxide reduction from different technologies; 'Relative', as all the technologies examined are dependant on various primary sources; and 'Balance', as the cost of surplus CO 2 is quantified. According to conventional financial analysis, most of the technologies examined have the potential to provide positive returns on the investments especially for those with an environmentally conscious agenda. Further reduction of up to 30% of most installed alternative energy systems cost is required to compete with an investment in, e.g., a UK pension scheme. Using the 'CARB financial analysis' the cost of reducing CO 2 has been quantified, and compared with the potential cost of climate change impact. Conventional installed solar technologies are not financially attractive both with a pay back period calculations and 'CARB financial analysis' under current market costs and governmental subsidy regimes. Heat recovery technologies could be sensible investments, both in financial and environmental terms under particular assumptions; especially if the investment budget is small. The use of cogeneration technologies provides a financial advantage in the attempt to minimise the cost of climate change impact, as pay back period of such investment could be less than 7 yr, and the cost of CO 2 saved could be two to seven times less than the global damage cost of carbon emissions.

More and more houses in rural areas of Sabah are connected to solar powered infra structural development needs such as street lights, radio repeater station, telecommunication and high-voltage beacons. To meet the infra structural and environmental challenges, especially in remote locations and with prospects of greater economic competitiveness, central and distributed grid connected photovoltaic systems are now being evaluated in Mandahan, Papar and in Marak Parak, Kota Marudu. This paper reports on the progress with the application of the technology and the prospects for wider dissemination

A Study on Guidelines for the Utilization of Unproven MMIS Technology In Nuclear Power Plant Application

International Nuclear Information System (INIS)

Kang, Sung Kon; Shin, Yeong Cheol; Bae, Byoung Hwan

2007-01-01

New MMIS (Man Machine Interface System) technology is rapidly advanced as digital technology provides opportunity for more functionality and better cost effectiveness and NPP (Nuclear Power Plant) operators are inclined to use the new technology for the construction of new plant and for the upgrade of existing plants. However, this new technology poses risks to the NPP operators at the same time. These risks are mainly due to the poor reliability of newly developed technology. KHNP's past experiences with the new MMIS equipment shows many cases of reliability problem. And their consequences include unintended plant trips, lowered acceptance of the new digital technology by the plant I and C maintenance crew, and increased licensing burden in answering for questions from the nuclear regulatory body. Considering the fact that the risk of these failures in the nuclear plant operation is far greater than those in other industry, utilities require proven technology for the MMIS in nuclear power plants. So that new MMIS technology might be testified as proven technology, guidelines for the utilization of unproven MMIS technology in nuclear power plant application is required for applying new advanced MMIS technology which is apparently needed to obtain a definite gain in simplicity or performance

Solar energy utilizing technology for future cities

Energy Technology Data Exchange (ETDEWEB)

Mori, Kei

1987-11-20

This report proposes solar energy utilizing technologies for future cities, centering on a system that uses Fresnel lenses and optical fiber cables. This system selects out beams in the visible range and the energy can be sent to end terminals constantly as long as sunlight is available. Optical energy is concentrated 4,000-fold. The system can provide long-distance projection of parallel rays. It will be helpful for efficient utilization of light in cities and can increase the degree of freedom in carrying out urban development. The total efficiency for the introduction into optical fiber can be up to 40 percent. With no heating coil incorporated, there is no danger of fire. The standard size of a light condenser is 2 m in dome diameter and 2.5 m in height. Auxiliary artificial light is used for backup purposes when it is cloudy. Heat pumps operating on solar thermal energy are employed to maintain air conditioning for 24 hours a day in order to ensure the establishment of an environment where residential areas exist in the neighborhood of office areas. Seven automatic solar light collection and transfer systems are currently in practical use at the Arc Hills building. The combination of Fresnel lens and optical fiber is more than six times as high in efficiency as a reflecting mirror. (5 figs, 3 tabs, 8 photos, 6 refs)

Syed Jamaludin, S. Z. H.; Mahayuddin, S. A.; Hamid, S. H. A.

2018-04-01

Developing countries including Malaysia have begun to comprehend the needs for affordable and sustainable housing development. The majority of the population is still aspiring for a comfortable, safe and reasonably priced house. Households in the low-middle income range face difficulties to find housing that can satisfy their needs and budget. Unfortunately, most of the housing development programs are considering affordability rather than sustainable aspects. Furthermore, developers are more interested in profit and neglect sustainability issues. Thus, the aim of this paper is to review the challenges in integrating affordable housing and sustainable practices in Malaysia. This paper is produced based on an extensive literature review as a basis to develop strategies of integrated affordable and sustainable housing in Malaysia. The challenges are divided into four sections, namely market challenges, professional challenges, societal challenges and technological challenges. The outcomes of this paper will assist in the decision making involving housing development and in enhancing quality of life for sustainable communities.

The SURE House (Solar Decathlon 2015)

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

This paper discusses the technical potential for hydrogen used as an energy storage medium to couple time-dependent renewable energy into time-dependent electric utility loads. This analysis will provide estimates of regional and national opportunities for hydrogen production, storage and conversion, based on current and near-term leading renewable energy and hydrogen production and storage technologies. Appropriate renewable technologies, wind, photovoltaics and solar thermal, are matched to their most viable regional resources. The renewables are assumed to produce electricity which will be instantaneously used by the local utility to meet its loads; any excess electricity will be used to produce hydrogen electrolytically and stored for later use. Results are derived based on a range of assumptions of renewable power plant capacity and fraction of regional electric load to be met (e.g., the amount of hydrogen storage required to meet the Northwest region`s top 10% of electric load). For each renewable technology national and regional totals will be developed for maximum hydrogen production per year and ranges of hydrogen storage capacity needed in each year (hydroelectric case excluded). The sensitivity of the answers to the fraction of peak load to be served and the land area dedicated for renewable resources are investigated. These analyses can serve as a starting point for projecting the market opportunity for hydrogen storage and distribution technologies. Sensitivities will be performed for hydrogen production, conversion. and storage efficiencies representing current and near-term hydrogen technologies.

building-components industry, energy or waste networks and providers, and planning regulations. The professional partners for the projects, such as housing associations and engineers, are equally affected by the institutional context, but their position is different from that of residents. They may for example be more anchored in governmental or professional regulations. To structure this dynamic, the research distinguishes three interrelated aspects: • ACTORS / involved in the (realisation of projects: social practices of residents and their professional partners in co-creation. • CONTEXT / the structural forces surrounding the projects, specifically the macroinstitutional regimes. This also includes culturally determined interpretations of sustainability, technology, participation, societal roles, sharing, and so on. • TECHNOSPHERE / specifically building technology and utilities, focussing on energyrelated design and engineering of the co-housing projects. The thesis is primarily based on qualitative methods, as it found that reliable quantitative data are as yet unavailable. Looking for effective low-impact energysolution in co-housing, quantitative data remain however necessary and this thesis elaborates on pitfalls and possibilities for their accumulation. Empirical material from Dutch case-studies form the core of the research. Examples were also taken from countries where the re-emergence of co-housing is most visible and articulate: Belgium, France, Germany, the UK and Switzerland. Co-housing continues to develop and gain experiences with competences, such as communication skills and the ability to work cross-disciplinarily. The building industry and engineering professions increasingly call for such capabilities, but resident-led urban development have not yet entered the urbanism and engineering curricula. Therefore, opportunities should be provided for future professionals not only to acquire such capabilities but also to address fundamental questions

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.

One of the largest examples of a community-based, mutual-help residential community for high risk substance abuse individuals is Oxford House. In the U.S., over 9,800 people live in these self-run dwellings where they obtain jobs, pay utility bills, and learn to be responsible citizens. Beginning with one single rented residence in the mid 1970s, Oxford Houses now number over 1,300. These rented homes are helping to deal with drug addiction and community re-entry by providing stable housing without any limits on length of stay, a network of job opportunities, and support for abstinence. An exploration of the research on these unique settings highlights the strengths of such a community-based approach to addressing addiction. New roles for psychologists in working with these types of support systems are identified. PMID:20577571

2004-01-01

The life cycle assessment of the mobile phone housing in Motorola(China) Electronics Ltd. was carried out, in which materials flows and environmental emissions based on a basic production scheme were analyzed and assessed. In the manufacturing stage, such primary processes as polycarbonate molding and surface painting are included, whereas different surface finishing technologies like normal painting, electroplate, IMD and VDM etc. were assessed. The results showed that housing decoration plays a significant role within the housing life cycle. The most significant environmental impact from housing production is the photochemical ozone formation potential. Environmental impacts of different decoration techniques varied widely, for example, the electroplating technique is more environmentally friendly than VDM. VDM consumes much more energy and raw material. In addition, the results of two alternative scenarios of dematerialization showed that material flow analysis and assessment is very important and valuable in selecting an environmentally friendly process.

We have specially follow the aspects concerning to the distribution of occurrence forms, composition and structure of mineral and organic components, and the genetic correlations between these in conditions of soils from glass houses, respectively. The results regarding the distribution tendencies on profile and the correlations between mineral and organic components of studied soils have been correlated with the results of microscopic, spectral (IR and Raman) and X-ray diffraction studies, and with the results of thermodynamic modelling of mineral equilibriums and dynamics of pedogenesis processes, in conditions of soils from glass houses. The utilization of intensive cultivation technologies of vegetables in glass houses determined the degradation of morphological, physical and chemical characteristics of soils, by fast evolution of salted processes (salinization and / or sodization), compaction, carbonatation, eluviation-illuviation, frangipane formation, stagnogleization, gleization, etc. Under these conditions, at depth of 30-40 cm is formed a compact and impenetrable horizon with frangipane characteristics, expresses more or less. The aspects about the formation of frangipane horizon in soils from glasshouses are not yet sufficiently know. Whatever of the formation processes, the frangipane horizons determined a sever segregation in pedo-geochemical evolution of soils from glasshouses, with very important consequences on the agrochemical quality of these soils. The soils from glass houses are characterized by a very large variability of mineralogy and chemistry, which are traduced by intense modifications of superior horizons, in many cases there are conditions for the apparition of new pedogenetic horizons through new-pedogenesis processes. Under these conditions the definition of some general characteristics of soils from glasshouses is

Science.gov (United States)

Wallpe, Jordan P.

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

PROCESS OF HOUSING TRANSFORMATION IN IRAN

Directory of Open Access Journals (Sweden)

Mahta Mirmoghtadaee

2009-06-01

Full Text Available Iranian houses have changed dramatically in recent decades. The changes took place in three different periods in which social, economic, and technological transformations caused physical and morphological changes. This paper discusses the process of change analytically, emphasizing the importance of compatibility between the house form and lifestyle. The spatial characteristics of traditional Iranian houses reflect natural, geographical, and cultural needs. There was a harmony between people’s needs and the physical characteristics of the house. In the transition period, however, a new residential type appeared, in which living spaces were categorized according to their general functions. Spatial arrangement, together with plan layout and proportions, facilitated the limited potential for varied lifestyles. In the contemporary period, apartment buildings became prevalent. In this new type of residence, the physical characteristics of the house have changed considerably, while living habits and lifestyles have not changed at the same pace. This paper concludes that habitats should be physically harmonious with traditions and lifestyles; otherwise, residents would react and try to change the environment according to their wishes. When the environment itself is not changeable, residents have to adapt themselves to their new conditions; consequently, some valuable traditions would be lost forever.

From Natural Monopoly to Public Utility: Technological Determinism and the Political Economy of Infrastructure in Progressive-Era America.

Science.gov (United States)

Plaiss, Adam

In present-day debates regarding telecommunication policy, one frequently hears the terms natural monopoly and public utility. This article investigates the origins of these ideas, finding that Richard T. Ely-a celebrated American economist of the late nineteenth century-embedded in the term "natural monopoly" a narrative of technological determinism. By arguing that certain services had monopolizing tendencies hardwired into them, Ely argued for their regulation. Ely's theory of natural monopoly formed the basis of Wisconsin's 1907 public utilities law, which served as a model for many other states' regulatory policies. The modern notion of public utility thus carries with it the technological determinism of Ely's natural monopoly idea. By tracing the lineage of these two terms, this article recaptures the influence that activists and progressive politicians exercised over the formation of large technological systems during the Second Industrial Revolution.

The article speaks about radon entry ways to houses, the technologies of controlling the level of radon in indoors and four possible ways to solve the problem of high concentration of radon gas in housing and protection from being gathered to a certain extent that is harmful to health. These methods are: removal of the radon source, modifying the radon source, ventilation and air filtration. The article also addresses the impact of reducing the consumption of heating energy in homes and buildings using thermal insulators in floors, walls, ceilings and doors and making double glazed windows that confine the air. It has been proven that there is a steady relationship between energy conservation measures in housing and the increase of radon concentration by two to three times. In a lot of buildings, where conservation measures have been taken, materials to conserve heat are used, which themselves launch radon and this may lead to increased levels of the gas in the housing.

Roof top extensions for multifamily houses in Slovakia

Science.gov (United States)

Szekeres, K.

2010-12-01

In the countries of the European Union with the exception of Malta, approximately 100.1 million multifamily dwelling units are situated. These dwellings count for an average of 47.5% of the total housing stock in European Union countries. At present in Slovakia and also other countries of Central and Eastern Europe, there are vast housing areas which were built after World War II. Slovakia's multifamily housing stock was privatized during the 1990s. Considering that the economy of Slovakia is not capable of replacing the existing housing fund, which is located in the multifamily houses that were built after World War II, it is necessary to place an increased emphasis on the renovation of this housing fund. The expenditures for the refurbishment of multifamily housing stock in recent decades, when compared with the demand, have been at a very low level. The main problems involving the current multifamily housing stock in Slovakia are: the need for modernization, the low level of energy efficiency, and the insufficient level of building maintenance. One of the options for creating sufficient sources for the renovation of apartment buildings is to utilize the roofs of apartment buildings as construction areas for building additional floors (over - roofing). The means acquired from the sale of the new floors after deducting the costs can be used for renovation. It is a matter of a one-time possibility, which is limited by many factors that depend on the localization and constructive technical solutions for apartment buildings. This article is an outcome of the SuReFit "Sustainable Roof Extension Retrofit for High-Rise Social Housing in Europe" international research project.

Energy Efficient Industrialized Housing Research Program, Center for Housing Innovation, University of Oregon and the Florida Solar Energy Center

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.

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

Emergy Evaluation of Dwelling Operation in Five Housing Units of Montreal Island, Canada

Full Text Available Sustainability of cities and the environmental implications of high resource utilization by the domestic sector are growing concerns related to urban regions. Well-informed urban planning decision-making is an essential tool to help in the task and, for that, an important point to consider is the influence of parameters like residential density and housing typology on the intensity of resource utilization. Emergy synthesis, a life-cycle energy analysis methodological approach that considers the interaction of natural and human-made flows, was used to evaluate the environmental support for dwelling operational stage in five typical present-day housing units on the island of Montreal. As expected, resource utilization, measured as total emergy used, was positively correlated to housing unit size both with respect to number of occupants and dwelling size. Results suggest that variables affecting notably the intensity of resource utilization are per household income and per dweller habitable space and, while a higher income increased per capita emergy in all cases, increasing space availability per resident did not result in a decrease of empower density after 50 m2/person. Future work should consider lower and higher densities and analyses at the scale of blocks, neighborhoods and urban planning zones.

Shear Seal Valve: En-Tegrity - Advanced subsea well control technology. With the growing complexity of well interventions operations such as zone isolations, chemical treatment, sand removal and side track re-completion drilling, there is an increasing demand for an efficient light well intervention service equipment. This paper details the design, development and qualification program undertaken to introduce a new technology for well interventions operations. The Shear Seal Valve provides dual barrier sealing integrity that is capable of cutting large diameter coiled tubing, drill pipe and intervention tooling within a single compact housing. The hydraulic design of the valve minimizes operating volumes and negates the requirement for mechanical ram locks therefore greatly simplifying control system complexity. Utilizing dual metal to metal sealing technology and a fail safe close rational the system is ideally suited to HPHT applications providing optimum operational integrity. (Author)

Three important present-day technology development settings involve significant overlap between government and private sectors. The Advanced Research Project Agency for Energy (ARPA-E) supports a wide range of "high risk, high return" projects carried out in academic, non-profit or private business settings. The Materials Genome Initiative (MGI), based in the White House, aims at radical acceleration of the development process for advanced materials. California public utilities such as Pacific Gas & Electric operate under a structure of financial returns and political program mandates that make them arms of public policy as much as independent businesses.

Building a sustainable future: Bioclimatic house

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

Full Text Available New districts and ‘eco-cities’ built between the '90s and 2000s in the Scandinavian countries and the UK, as well as in Germany, France, the Netherlands and in other European countries, represent a decisive overcoming of the experimental phase where the ecological housing was just an innovative approach limited to small pilot projects. In these districts the social housing is implemented according to percentages corresponding to the housing policies of the different countries. The role of technological choices and the characteristics of the building process have been crucial for building quality to reduce environmental impacts and to support and promote new ecologically oriented lifestyles and a wider social inclusion.

Full Text Available The article gives an overview of key aspect of housing in Municipality of Ljubljana. 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.

The U.S. Space Exploration Policy has as a cornerstone the establishment of an outpost on the moon. This lunar outpost wil1 eventually provide the necessary planning, technology development, testbed, and training for manned missions in the future beyond the Moon. As part of the overall activity, the National Aeronautics and Space Administration (NASA) is investigating how the in situ resources can be utilized to improve mission success by reducing up-mass, improving safety, reducing risk, and bringing down costs for the overall mission. Marshall Space Flight Center (MSFC), along with other NASA centers, is supporting this endeavor by exploring how lunar regolith can be mined for uses such as construction, life support, propulsion, power, and fabrication. An infrastructure capable of fabrication and nondestructive evaluation will be needed to support habitat structure development and maintenance, tools and mechanical parts fabrication, as well as repair and replacement of space-mission hardware such as life-support items, vehicle components, and crew systems, This infrastructure will utilize the technologies being developed under the In Situ Fabrication and Repair (ISFR) element, which is working in conjunction with the technologies being developed under the In Situ Resources Utilization (ISRU) element, to live off the land. The ISFR Element supports the Space Exploration Initiative by reducing downtime due to failed components; decreasing risk to crew by recovering quickly from degraded operation of equipment; improving system functionality with advanced geometry capabilities; and enhancing mission safety by reducing assembly part counts of original designs where possible. This paper addresses the need and plan for understanding the properties of the lunar regolith to determine the applicability of using this material in a fabrication process. This effort includes the development of high fidelity simulants that will be used in fabrication processes on the ground to

Propellantless Attitude Control of Solar Sail Technology Utilizing Reflective Control Devices

Science.gov (United States)

Munday, Jeremy

2016-01-01

Solar sails offer an opportunity for a CubeSatscale, propellant-free spacecraft technology that enables long-term and long-distance missions not possible with traditional methods. Solar sails operate using the transfer of linear momentum from photons of sunlight reflected from the surface of the sail. To propel the spacecraft, no mechanically moving parts, thrusters, or propellant are needed. However, attitude control, or orientation, is still performed using traditional methods involving reaction wheels and propellant ejection, which severely limit mission lifetime. For example, the current state of the art solutions employed by upcoming missions couple solar sails with a state of the art propellant ejection gas system. Here, the use of the gas thruster has limited the lifetime of the mission. To solve the limited mission lifetime problem, the Propellantless Attitude Control of Solar Sail Technology Utilizing Reflective Control Devices project team is working on propellantless attitude control using thin layers of material, an optical film, electrically switchable from transparent to reflective. The technology is based on a polymer-dispersed liquid crystal (PDLC), which allows this switch upon application of a voltage. This technology removes the need for propellant, which reduces weight and cost while improving performance and lifetime.

The Energy & Environmental Research Center (EERC) is conducting a consortium-based effort directed toward resolving the mercury (Hg) control issues facing the lignite industry. Specifically, the EERC team--the EERC, EPRI, URS, ADA-ES, Babcock & Wilcox, the North Dakota Industrial Commission, SaskPower, and the Mercury Task Force, which includes Basin Electric Power Cooperative, Otter Tail Power Company, Great River Energy, Texas Utilities (TXU), Montana-Dakota Utilities Co., Minnkota Power Cooperative, BNI Coal Ltd., Dakota Westmoreland Corporation, and the North American Coal Company--has undertaken a project to significantly and cost-effectively oxidize elemental mercury in lignite combustion gases, followed by capture in a wet scrubber. This approach will be applicable to virtually every lignite utility in the United States and Canada and potentially impact subbituminous utilities. The oxidation process is proven at the pilot-scale and in short-term full-scale tests. Additional optimization is continuing on oxidation technologies, and this project focuses on longer-term full-scale testing. The lignite industry has been proactive in advancing the understanding of and identifying control options for Hg in lignite combustion flue gases. Approximately 1 year ago, the EERC and EPRI began a series of Hg-related discussions with the Mercury Task Force as well as utilities firing Texas and Saskatchewan lignites. This project is one of three being undertaken by the consortium to perform large-scale Hg control technology testing to address the specific needs and challenges to be met in controlling Hg from lignite-fired power plants. This project involves Hg oxidation upstream of a system equipped with an electrostatic precipitator (ESP) followed by wet flue gas desulfurization (FGD). The team involved in conducting the technical aspects of the project includes the EERC, Babcock & Wilcox, URS, and ADA-ES. The host sites include Minnkota Power Cooperative Milton R. Young

Over one million HUD-supported public housing units provide rental housing for eligible low-income families across the country. A survey of over 100 public housing authorities (PHAs) across the country indicated that there is a high level of interest in developing low-cost solutions that improve energy efficiency and can be seamlessly included in the refurbishment process. Further, PHAs, have incentives (both internal and external) to reduce utility bills. ARIES worked with four PHAs to develop packages of energy efficiency retrofit measures the PHAs can cost-effectively implement with their own staffs in the normal course of housing operations at the time when units are refurbished between occupancies. The energy efficiency turnover protocols emphasized air infiltration reduction, duct sealing, and measures that improve equipment efficiency. ARIES documented implementation in 18 housing units. Reductions in average air leakage were 16% and duct leakage reductions averaged 23%. Total source energy consumption savings due to implemented measures was estimated at 3-10% based on BEopt modeling with a simple payback of 1.6 to 2.5 years. Implementation challenges were encountered mainly related to required operational changes and budgetary constraints. Nevertheless, simple measures can feasibly be accomplished by PHA staff at low or no cost. At typical housing unit turnover rates, these measures could impact hundreds of thousands of units per year nationally.

In this paper a backpropagation neural network is utilized to perform house cluster segmentation from Google Earth data. The algorithm is subjected to identify houses in the image based on the RGB pattern within each pixel. Training data is given through cropping selection for a target that is a house cluster and a non object. The algorithm assigns 1 to a pixel belong to a class of object and 0 to a class of non object. The resulting outcome, a binary image, is then utilized to perform quantification to estimate the number of house clusters. The number of the hidden layer is varying in order to find its effect to the neural network performance and total computational time

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

Science.gov (United States)

DeChambeau, Brian

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

The benefits of Pathways Housing First in addressing chronic homelessness for persons with severe mental illness have been well established. However, the implementation and effectiveness of such programs in rural areas has yet to be examined. We described the model’s adaptations in Vermont, including the use of hybrid assertive community treatment–intensive case management teams, which consisted of service coordinators with geographically based caseloads (staff/client ratio of 1:20) and regional multidisciplinary specialists. The program’s innovative and widespread inclusion of technology into operations facilitated efficiency and responsiveness, and a pilot telehealth initiative supplemented in-person client visits. The program achieved a housing retention rate of 85% over approximately 3 years, and consumers reported decreased time spent homeless, demonstrating that program adaptations and technological enhancements were successful.

Microbiology was in former times nearly exclusively used in the region of food and for the production of antibiotics. Biomass production must be seen as a key development among the new biotechnologies. Biomass consists of high-fat and protein-rich microorganisms, which can serve as animal feed. These microorganisms not only grow on cellulose wastes and other biological basic substrates but also on mineral oil and methanol. The energy consumption is relatively low. The increasing knowledge of the problems of one-way-technologies for our time makes todays biotechnology seem to be a very promising development. Biotechnology utilizes the cyclic metabolic way of the microorganisms and can in many cases lead back waste products to natural circulation.

Recent efforts have been directed towards utilizing CAD/CAM technology in the education of future dentists. The purpose of this pilot study was to investigate the feasibility of implementing CAD/CAM technology in instruction on preparing a tooth for restoration. Students at one dental school were assigned access to CAD/CAM technology vs. traditional preparation methods in a randomized, crossover design. In a convenience sample of a second-year class, seventy-six of the seventy-nine students volunteered to participate, for a response rate of 96 percent. Two analyses were performed on this pilot data: a primary effectiveness analysis comparing students' competency exam scores by intervention group (intention-to-treat analysis) and a secondary efficacy analysis comparing competency exam scores among students who reported using CAD/CAM versus those who did not. The effectiveness analysis showed no difference in outcomes by intervention group assignment. While student survey results indicated interest in utilizing the technology, the actual utilization rate was much less than one might anticipate, yielding a sample size that limited statistical power. The secondary analysis demonstrated higher mean competency exam scores for students reporting use of CAD/CAM compared to those who did not use the technology, but these results did not reach statistical significance (p=0.075). Prior research has investigated the efficacy of CAD/CAM in a controlled educational trial, but this study adds to the literature by investigating student use of CAD/CAM in a real-world, self-study fashion. Further studies should investigate ways in which to increase student utilization of CAD/CAM and whether or not increased utilization, with a larger sample size, would yield significant outcomes.

The EERC developed an applied research consortium project to test cost-effective mercury (Hg) control technologies for utilities burning bituminous coals. The project goal was to test innovative Hg control technologies that have the potential to reduce Hg emissions from bituminous coal-fired power plants by {ge}90% at costs of one-half to three-quarters of current estimates for activated carbon injection (ACI). Hg control technology evaluations were performed using the EERC's combustion test facility (CTF). The CTF was fired on pulverized bituminous coals at 550,000 Btu/hr (580 MJ/hr). The CTF was configured with the following air pollution control devices (APCDs): selective catalytic reduction (SCR) unit, electrostatic precipitator (ESP), and wet flue gas desulfurization system (WFDS). The Hg control technologies investigated as part of this project included ACI (three Norit Americas, Inc., and eleven Envergex sorbents), elemental mercury (Hg{sup 0}) oxidation catalysts (i.e., the noble metals in Hitachi Zosen, Cormetech, and Hitachi SCR catalysts), sorbent enhancement additives (SEAs) (a proprietary EERC additive, trona, and limestone), and blending with a Powder River Basin (PRB) subbituminous coal. These Hg control technologies were evaluated separately, and many were also tested in combination.

In the Hot Cell Bank 3 of the Radioisotope Production Facility, production and dispense of I-131 solution and capsule that are used for the diagnosis and treatment of thyroid cancer are made. The original charcoal filter housings installed in 1994 and were utilized until the leakage of a very small amount of radio-iodine was found due to the erroneous installation of the charcoal filter in the filter housing. Thus the production of I-131 was discontinued until the repair and performance testing of the filter housing and the inspection by the regulatory body were finished. Although the production of I-131 was resumed, there was a desire for installing the brand-new charcoal filter housing which has an intrinsically safe design and no possibility of leakage. This report describes the design, fabrication and installation of brand-new charcoal filter housing. And also were described the dismantlement of the old housings, the assessment of the structural integrity of the shielding concrete wall and the installation of the shielding doors

2014-01-01

The success of long-duration missions will depend on resource recovery and the self-sustainability of life support technologies. Current technologies used on the International Space Station (ISS) utilize chemical and mechanical processes, such as filtration, to recover potable water from urine produced by crewmembers. Such technologies have significantly reduced the need for water resupply through closed-loop resource recovery and recycling. Harvesting the important components of urine requires selectivity, whether through the use of membranes or other physical barriers, or by chemical or biological processes. Given the chemical composition of urine, the downstream benefits of urine processing for resource recovery will be critical for many aspects of life support, such as food production and the synthesis of biofuels. This paper discusses the beneficial components of urine and their potential applications, and the challenges associated with using urine for nutrient recycling for space application.

Science Environment Technology and Society (SETS) approach helps students to connect science concept with the other aspects. This allows them to achieve a clearer depiction of how each concept is linked with the other concepts in SETS. Taking SETS into account will guide students to utilize science as a productive concept in inventing and developing technology, while minimizing its negative impacts on the environment and society. This article discusses the implementation of Sundanese local wisdoms, that can be found in the local stilt house (rumah panggung), in the Building Construction subject in vocational high school on Building Drawing Technique expertise. The stilt house structural system employs ties, pupurus joints, and wedges on its floor, wall, and truss frames, as well as its beams. This local knowledge was incorporated into the Building Construction learning program and applied on the following basic competences: applying wood’s specification and characteristics for building construction, managing wood’s specification and characteristics for building construction, analyzing building structure’s type and function based on their characteristics, reasoning building structure’s type and function based on their characteristics, categorizing wood construction works, and reasoning wood construction works. The research result is the Sundanese traditional-local-wisdom-based learning design of the Building Construction subject.

Deslich, Stacie; Coustasse, Alberto

2014-05-01

Telemedicine has been utilized in various healthcare areas to achieve better patient outcomes, lower costs of providing services, and increase patient access to care. Tele-intensive care unit (ICU) technology has been introduced as a way to provide effective ICU services to patients with reduced access, as well as to decrease costs and improve patient care. The methodology for this qualitative study was a literature search and review of case studies. The search was limited to sources published in the last 10 years (2003-2013) in the English language. In total, 55 references were used for this research exploration inquiry. Tele-ICU was found to be an effective way to use technology to decrease costs of providing intensive care, while improving patient outcomes such as mortality and length of stay. Several case studies supported the use of telemedicine in ICUs to provide intensive care to patients who lived in rural areas and lacked access to traditional ICUs. Furthermore, it was noted that, although the initial costs for tele-ICU startup were significant, as much as $100,000 per bed, the benefits of the utilization of this technology can offset those costs by reducing costs by 24% via decreased length of stay for patients. The findings of this study have suggested that the implementation of tele-ICU may have been more beneficial than costly, and it may have provided healthcare organizations the opportunity to increase quality of care and decrease mortality, while it might have decreased costs of delivering ICU services in both rural and urban areas.

2012-06-01

Full Text Available Abstract Background Weaning of beef calves is a necessary husbandry practice and involves separating the calf from its mother, resulting in numerous stressful events including dietary change, social reorganisation and the cessation of the maternal-offspring bond and is often accompanied by housing. While much recent research has focused on the physiological response of the bovine immune system to stress in recent years, little is known about the molecular mechanisms modulating the immune response. Therefore, the objective of this study was to provide new insights into the molecular mechanisms underlying the physiological response to weaning at housing in beef calves using Illumina RNA-seq. Results The leukocyte transcriptome was significantly altered for at least 7 days following either housing or weaning at housing. Analysis of differentially expressed genes revealed that four main pathways, cytokine signalling, transmembrane transport, haemostasis and G-protein-coupled receptor (GPRC signalling were differentially regulated between control and weaned calves and underwent significant transcriptomic alterations in response to weaning stress on day 1, 2 and 7. Of particular note, chemokines, cytokines and integrins were consistently found to be up-regulated on each day following weaning. Evidence for alternative splicing of genes was also detected, indicating a number of genes involved in the innate and adaptive immune response may be alternatively transcribed, including those responsible for toll receptor cascades and T cell receptor signalling. Conclusions This study represents the first application of RNA-Seq technology for genomic studies in bovine leukocytes in response to weaning stress. Weaning stress induces the activation of a number of cytokine, chemokine and integrin transcripts and may alter the immune system whereby the ability of a number of cells of the innate and adaptive immune system to locate and destroy pathogens is

installation labor and materials, and $627 for overhead and management), and the benefit-to-cost ratio was 1.48. A general trend toward higher-than-average fuel-oil savings was observed in houses with high pre-weatherization fuel-oil consumption. Program savings could likely be increased by targeting higher energy consumers for weatherization, although equity issues would have to be considered. Weatherization measures associated with higher-than-average savings were use of a blower door for air-sealing, attic and wall insulation, and replacement space-heating systems. Space-heating system tune-ups were not particularly effective at improving the steady-state efficiency of systems, although other benefits such as improved seasonal efficiency, and system safety and reliability may have resulted. The Program should investigate methods of improving the selection and/or application of space-heating system tune-ups and actively promote improved tune-up procedures that have been developed as a primary technology transfer activity. Houses were more air-tight following weatherization, but still leakier than what is achievable. Additional technology transfer effort is recommended to increase the use of blower doors considering that only half the weatherized houses used a blower door during air sealing. A guidebook developed by a committee of experts and covering a full range of blower-door topics might be a useful technology transfer and training document. Weatherization appeared to make occupants feel better about their house and house environment.

Highlights: • Implementation of a modeling and design framework for the utilization of low grade heat. • Application of process simulator and optimization techniques for the design of technologies for heat recovery. • Systematic and holistic exploitation for the recovery of industrial low grade heat. • Demonstration of the applicability and benefit of integrated design and optimization framework through a case study. - Abstract: The utilization of low grade heat in process industries has significant potential for improving site-wide energy efficiency. This paper focuses on the techno-economic analysis of key technologies for energy recovery and re-use, namely: Organic Rankine Cycles (ORC), boiler feed water heating, heat pumping and absorption refrigeration in the context of process integration. Process modeling and optimization in a holistic manner identifies the optimal integrated configuration of these technologies, with rigorous assessment of costs and technical feasibility of these technologies. For the systematic screening and evaluation of design options, detailed process simulator models are evaluated and optimization proceeds subject to design constraints for the particular economic scenarios where technology using low grade heat is introduced into the process site. Case studies are presented to illustrate how the proposed modeling and optimization framework can be useful and effective in practice, in terms of providing design guidelines and conceptual insights for the application of technologies using low grade heat. From the case study, the best options during winter are the ORC giving a 6.4% cost reduction for the ideal case with low grade heat available at a fixed temperature and boiler feed water heating giving a 2.5% cost reduction for the realistic case with low grade heat available at a range of temperatures. Similarly during summer boiler feed water heating was found to be the best option giving a 3.1% reduction of costs considering a

Full Text Available The solid slaughter house waste (SSW in Indonesia is generally disposed of into open dumped landfill. This type of solid waste can cause odor and atmospheric pollution if discharged directly into the environment. Additionally, it may spread disease due to the nesting vectors, and the resulting leachate can lead to groundwater contamination. This paper reviews the characterization of slaughter house (SH types and SSW generation potential and to review the development of treatment technology of SSW and its application. The SH in Indonesia is divided into 3 classes, namely: 1 SH for large and small ruminants; 2 SH for poultry; 3 SH for pigs. Application technologies in Indonesia include compost and biogas technologies, and the use of rumen content for animal feed. Problem in biogas technology is generally caused by the high nitrogen content in the SSW. The most suitable raw material for biogas production is herbivore waste. The main advantages of using SSW for compost production are: the appropriate characteristics for composting process, free of hazardous contaminant, and appropriate composting technologies are available to reduce environmental problems caused by SSW. In addition, rumen content is considered to be a potential alternative for animal feed because have high content of amino acids (approximately 73.4% of the total protein and rich in vitamin B complex. Among the disadvantages, the composting process of SSW requires long time period and generate air pollutants, such as ammonia and hydrogen sulphide.

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.

Radical transformation carried out in the sector of housing and communal services (HCS, primarily associated with the formation of the new management model, which reflects the market relationship between the subjects and objects of management. The necessity of transition to new management models in housing and communal services is caused by the deregulation of the sector, separation of functions of owner, customer and producers, suppliers of housing and communal services, formation of private ownership of objects of housing and communal services. The relevance of the research topic is dictated by the low quality of management at all levels of the system of housing and communal services of Russia, insufficient knowledge of the specifics of management of the industry, as well as the need to develop ways to improve management efficiency, to ensure its exit from the crisis and further development. Development of system of housing and communal services becomes impossible without the use of new forms, methods of management of organizations. Consequently, the efficiency of management is relevant and very important problem, both for the theory and practice of management in this area of work.

Accidental falls are a major public health concern among people of all ages. Little is known about whether an individual-level housing-based socioeconomic status measure is associated with the risk of accidental falls. Among 12,286 Mayo Clinic Biobank participants residing in Olmsted County, Minnesota, subjects who experienced accidental falls between the biobank enrollment and September 2014 were identified using ICD-9 codes evaluated at emergency departments. HOUSES (HOUsing-based Index of SocioEconomic Status), a socioeconomic status measure based on individual housing features, was also calculated. Cox regression models were utilized to assess the association of the HOUSES (in quartiles) with accidental fall risk. Seven hundred eleven (5.8%) participants had at least one emergency room visit due to an accidental fall during the study period. Subjects with higher HOUSES were less likely to experience falls in a dose-response manner (hazard ratio: 0.58; 95% confidence interval: 0.44-0.76 for comparing the highest to the lowest quartile). In addition, the HOUSES was positively associated with better health behaviors, social support, and functional status. The HOUSES is inversely associated with accidental fall risk requiring emergency care in a dose-response manner. The HOUSES may capture falls-related risk factors through housing features and socioeconomic status-related psychosocial factors. Copyright © 2017 Elsevier Inc. All rights reserved.

1977-01-01

In the Federal Republic of Germany, analyses and forecasts of the energy supply and energy consumption have revealed five major sectors in which extensive R and D activities should be carried out: nuclear energy, coal technology, the utilization of solar energy, techniques for the economical use of energy, and nuclear fusion. Of these sectors, only nuclear energy will be able to make a major contribution to our energy supply both in the near future and over a longer period. The available capacity for mining the large deposits of coal in the Federal Republic of Germany can be increased only gradually and will therefore not make an appreciable contribution until a later date. Another fact to be considered is that a rapidly expanding utilization of this source of energy entails very heavy pollution of the environment. The utilization of solar energy in Central Europe will probably be possible only for supplying warm water for industry and for heating buildings. In the long term, solar energy will contribute only a small percentage of energy to the supply required by the Federal Republic of Germany. Intensive efforts are being made to develop technologies for the more economical use of energy. The priorities in this sector are the installation of district heating systems using waste heat from power stations, and the improved heat insulation of houses. It is not anticipated that the technical utilization of nuclear fusion will be introduced before the end of this century. Nonetheless, this source of energy still constitutes a possibility offering an extremely great potential in the long term, with the result that every effort is being made to put it to good use. The work being carried out in this field in the Federal Republic of Germany is being closely coordinated with the relevant activities undertaken by the other member countries of the European Community.

Japanese utilities' plutonium utilization program

Matsuo, Yuichiro.

1996-01-01

Japan's 10 utility companies are working and will continue to work towards establishing a fully closed nuclear fuel cycle. The key goals of which are: (1) reprocessing spent fuel; (2) recycling recovered uranium and plutonium; and (3) commercializing fast breeder technology by around the year 2030. This course of action by the Japanese electric power industry is in full accordance with Japan's national policy outlined in the government's report ''The Long-Term Program for Research, Development, and Nuclear Energy,'' which was published in June 1994. The Japanese civilian nuclear program is a long-term program that looks into the 21st century and beyond. It is quite true that sustaining the recycling option for energy security and the global environment demands a large investment. For it to be accepted by the public, safety must be the highest priority and will be pursued at a great cost if necessary. In its history, Japan has learned that as technology advances, costs will come down. The Japanese utility industry will continue investment in technology without compromising safety until the recycling option becomes more competitive with other options. This effort will be equally applied to the development of the commercial FBRs. The Japanese utility industry is confident that Japan's stable policy and strong objective to develop competitive and peaceful technology will contribute to the global economy and the environment without increasing the threat of plutonium proliferation

2017-03-09

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

Citizen utilities: The emerging power paradigm

International Nuclear Information System (INIS)

Green, Jemma; Newman, Peter

2017-01-01

The emergence of citizen-based power systems in an integrated grid has been anticipated for decades. We can reveal how this is emerging in practice due to the significant uptake of solar photovoltaics (solar PV) and now battery storage in Perth, Australia. The high cost of electricity, high radiant energy levels and easy access to cheap Chinese technology, has led to dramatic buying during Perth's recent boomtown years. The traditional uni-directional power system is rapidly disrupting and this paper assesses where this may lead and what it means for the grid. Results of detailed monitoring in a solar powered house along with the impact of a battery storage system show the impact on the traditional grid is substantial but it will still be needed and must therefore adapt to the new distributed, bi-directional energy system. Surveys and price trajectories reveal how the trends to solar power storage will continue and how a citizen utility paradigm will emerge as the future grid building block using new blockchain support systems. Responses from utilities are then see to be fight, flight or innovate. - Highlights: • Citizen based power systems are emerging in Perth, Western Australia. • Solar power and battery storage systems are disrupting traditional utilities. • The grid will still have a role in the new, distributed power system. • The new system will lead to economic localism and the democratisation of power.

We experimentally assessed the effect of outer housing layer materials and back side chip metallization. For lead-silver soldering of silicon chips, the best housing is that with a nickel outer layer rather than with a gold-plated one, because the resultant thermal resistance is lower and the absence of gold makes the technology cheaper. We obtained a 0.6 K/W thermal resistance for a 24 mm2 chip area.

Permanent supportive housing (PSH) is a widely-accepted solution to the challenge of chronic homelessness. While housing support and retention, physical health, and healthcare continue to be important for formerly homeless persons in PSH, "higher-order" and humanistic needs such as thriving have received less attention and as a result are less well understood in this population. One important indicator of thriving is the ability to establish and articulate life goals. This study utilizes longitudinal data from 421 formerly homeless adults prior to their move into PSH, and at 3-, 6- and 12-months after move-in (369 respondents completed all four interviews), to examine what life goals are articulated by this population and how those goals change over time. Prior to housing, most respondents articulated housing attainment as their primary life goal, whereas at follow-up interviews health goals, housing relocation, and financial goals became more prevalent. Aspirational goals (e.g., independence, self-improvement, artistic pursuits) were also common, but demonstrated a decrease over time in housing. Relationship goals remained common and consistent over time. Findings indicate that housing is a necessary, but perhaps not sufficient, step for improving thriving among formerly homeless adults. Implications for practice and future research are discussed. © Society for Community Research and Action 2018.

The Annual Report presents the fiscal year (FY) 1988 research activities and accomplishments, for the Biocatalysis Project of the U.S. Department of Energy, Energy Conversion and Utilization Technologies (ECUT) Division. The ECUT Biocatalysis Project is managed by the Jet Propulsion Laboratory, California Institute of Technology. The Biocatalysis Project is a mission-oriented, applied research and exploratory development activity directed toward resolution of the major generic technical barriers that impede the development of biologically catalyzed commercial chemical production. The approach toward achieving project objectives involves an integrated participation of universities, industrial companies and government research laboratories. The Project's technical activities were organized into three work elements: (1) The Molecular Modeling and Applied Genetics work element includes research on modeling of biological systems, developing rigorous methods for the prediction of three-dimensional (tertiary) protein structure from the amino acid sequence (primary structure) for designing new biocatalysis, defining kinetic models of biocatalyst reactivity, and developing genetically engineered solutions to the generic technical barriers that preclude widespread application of biocatalysis. (2) The Bioprocess Engineering work element supports efforts in novel bioreactor concepts that are likely to lead to substantially higher levels of reactor productivity, product yields and lower separation energetics. Results of work within this work element will be used to establish the technical feasibility of critical bioprocess monitoring and control subsystems. (3) The Bioprocess Design and Assessment work element attempts to develop procedures (via user-friendly computer software) for assessing the energy-economics of biocatalyzed chemical production processes, and initiation of technology transfer for advanced bioprocesses.

House passes energy bill with one-step plant licensing

International Nuclear Information System (INIS)

Anon.

1992-01-01

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

2017-09-01

Full Text Available This paper analyzes the relationship between house prices and household consumption in Turkey. We utilize twelve consecutive waves of the Turkish Statistical Institute (TURKSTAT Household Budget Surveys (HBS from 2003 to 2014. We construct a pseudo-panel data set using birth-year cohorts following Deaton (1985. We find that house price changes have a positive and significant effect on the growth of cohort consumption. Moreover, the effect of house price changes is stronger for home-owners and it intensifies as we move from young cohorts to old cohorts. We observe that there is a marginally significant and relatively weak relationship between the growth of cohort consumption and house price changes for tenants. However, our pooled sample set is restricted to young and middle-aged cohorts for tenants. In addition, we find that the rise of home-ownership ratio increases the growth of cohort consumption, while the spread of having outstanding housing debt depresses the growth of cohort consumption. Therefore, our empirical findings are in favor of the wealth channel argument.

Nuclear technology such as gamma-ray, eb and ion beams is widely use for the utilization of bio-resources. Irradiation using gamma ray from 60 Co and electron beam is commercially used for the sterilization and modification of materials. Polysaccharides such as chitosan, sodium alginate, carrageenan, cellulose, pectin were easily degraded by irradiation and induced various kinds of biological activities, i.e. anti-bacterial activity, elicitor activity, plant growth promotion, suppression of environmental stress on plants. Some carbohydrate derivatives, carboxymethylcellulose (CMC), carboxymethyl-starch and carboxymethyl-chitin/chitosan, can be crosslinked under certain radiation condition and produced the biodegradable hydrogel for medical and agricultural uses. Ion beams have also been applied for mutation breeding for medical and agricultural use. Ion beams have also been applied for mutation breeding and the production of positron-emitting isotopes such as 11 C, 13 N, etc. It was succeeded to induce several kinds of flower-color and flower-form mutants in chrysanthemum and carnation by ion beams that have never produced by gamma-ray. The positron emitting tracer imaging system (PETIS) has been developed to obtain a dynamic image of plant transport in situ. (Author)

Estimating potential of CO 2 emission reduction of non-capture CO 2 utilization (NCCU) technology was evaluated. NCCU is sodium bicarbonate production technology through the carbonation reaction of CO 2 contained in the flue gas. For the estimating the CO 2 emission reduction, process simulation using process simulator (PRO/II) based on a chemical plant which could handle CO 2 of 100 tons per day was performed, Also for the estimation of the indirect CO 2 reduction, the solvay process which is a conventional technology for the production of sodium carbonate/sodium bicarbonate, was studied. The results of the analysis showed that in case of the solvay process, overall CO 2 emission was estimated as 48,862 ton per year based on the energy consumption for the production of NaHCO 3 (7.4 GJ/tNaHCO 3 ). While for the NCCU technology, the direct CO 2 reduction through the CO 2 carbonation was estimated as 36,500 ton per year and the indirect CO 2 reduction through the lower energy consumption was 46,885 ton per year which lead to 83,385 ton per year in total. From these results, it could be concluded that sodium bicarbonate production technology through the carbonation reaction of CO 2 contained in the flue was energy efficient and could be one of the promising technology for the low CO 2 emission technology.

Photovoltaic technology for sustainability: An investigation of the distributed utility concept as a policy framework

Science.gov (United States)

Letendre, Steven Emery

The U.S. electric utility sector in its current configuration is unsustainable. The majority of electricity in the United States is produced using finite fossil fuels. In addition, significant potential exists to improve the nation's efficient use of energy. A sustainable electric utility sector will be characterized by increased use of renewable energy sources and high levels of end-use efficiency. This dissertation analyzes two alternative policy approaches designed to move the U.S. electric utility sector toward sustainability. One approach is labeled incremental which involves maintaining the centralized structure of the electric utility sector but facilitating the introduction of renewable energy and efficiency into the electrical system through the pricing mechanism. A second policy approach was described in which structural changes are encouraged based on the emerging distributed utility (DU) concept. A structural policy orientation attempts to capture the unique localized benefits that distributed renewable resources and energy efficiency offer to electric utility companies and their customers. A market penetration analysis of PV in centralized energy supply and distributed peak-shaving applications is conducted for a case-study electric utility company. Sensitivity analysis was performed based on incremental and structural policy orientations. The analysis provides compelling evidence which suggests that policies designed to bring about structural change in the electric utility sector are needed to move the industry toward sustainability. Specifically, the analysis demonstrates that PV technology, a key renewable energy option likely to play an important role in a renewable energy future, will begin to penetrate the electrical system in distributed peak-shaving applications long before the technology is introduced as a centralized energy supply option. Most policies to date, which I term incremental, attempt to encourage energy efficiency and renewables

Houses Based on Wood as an Ecological and Sustainable Housing Alternative—Case Study

2018-05-01

Full Text Available Sustainability of cities is currently a much-debated topic. The trend in Central Europe we witness nowadays is that people are going back from the impersonal and restrictive conditions of tower blocks to the more natural and relaxed conditions of family houses. New approaches to urbanization in the context of the sustainability of cities can be characterized by their use of innovative technologies and energetically efficient and ecologically acceptable construction materials. Companies have substantially responded to this trend, meeting the demand by offering a wide range of solutions. Alongside the traditional and long-established construction materials (brick, concrete, including wood, companies are introducing modern, innovative, and viable construction alternatives. Modern methods of construction (MMC, to which modern houses based on wood belong, promote the idea and application of environmentally and energetically efficient constructions. Just as the construction process itself significantly contributes to the depletion of natural resources, the production of construction materials contributes to significant environmental pollution and greenhouse emissions (particularly CO2. Sustainability assessments of construction projects increasingly involve the use of methodologies which assess sustainability criteria throughout a product’s Life-cycle. For our analysis of suburban housing clusters designed to serve as family houses, we chose an actual family house construction completed using a modern construction system based on wood. For the sake of comparing the modern construction method, we created an alternative model of a construction based on a traditional masonry construction system. The main objective of this contribution is to analyze selected variants of constructions in terms of environmental and economic sustainability characteristics, as part of a broader assessment of permanent sustainability, by applying the life-cycle assessment

A cornerstone of sexually transmitted infection (STI) prevention is the identification, tracing, and notification of sex partners of index patients. Although partner notification reduces disease burden and prevents new infections as well as reinfections, studies show that only a limited number of partners are ever notified. Electronic communication technologies, namely, the Internet, text messaging, and phone calls (i.e., e-notification), have the potential to expand partner services. We conducted a systematic review of studies that have investigated the acceptability and utility of e-notification. We identified 23 studies that met the following criteria: (a) 9 studies presented data on the acceptability of technology-based communications for contacting sex partner(s), and (b) 14 studies reported on the utilization of communication technologies for partner notification. Studies found high levels of interest in and acceptability of e-notification; however, there was little evidence for actual use of e-notification. Taken together, results suggest that electronic communications could have their greatest impact in notifying less committed partners who would otherwise be uninformed of their STI exposure. In addition, all studies to date have been conducted in resource-rich countries, although the low cost of e-notification may have its greatest impact in resource-constrained settings. Research is needed to determine the best practices for exploiting the opportunities afforded by electronic communications for expanding STI partner services.

Economising subsidies for green housing features: A stated preference approach

Directory of Open Access Journals (Sweden)

Yung Yau

2014-12-01

Full Text Available In light of the enormous amounts of energy and resources consumed by housing development and operations, many governments have started recognising the urgent need to promote green or eco-friendly housing with the aim of achieving sustainable development. Apart from regulations, governments can offer incentives to developers to provide green features in their developments by offering subsidies in various forms. However, such subsidisation is often uneconomical. In theory, market forces can lead to green housing provision without any government intervention if the market players are willing to pay extra for the green features of housing. Against this background, this article presents the findings of a study that compared potential homebuyers’ willingness to pay (WTP for various green housing features based on findings from a structured questionnaire survey in Macau. The housing attributes under investigation included uses of green materials (e.g., sustainable forest products and construction methods (e.g., prefabrication, energy-efficient technologies (e.g., LED lighting and water-saving devices (e.g., grey-water recycling systems. Results indicate that the respondents’ WTP was mainly motivated by economic incentives. Green housing attributes that can offer direct financial benefits corresponded to greater WTP. The policy implications of the research findings then follow.

Sustained housing-type social buffering following social housing in male rats.

Science.gov (United States)

Kiyokawa, Yasushi; Ishida, Aya; Takeuchi, Yukari; Mori, Yuji

2016-05-01

In social animals, recovery from the adverse effects of distressing stimuli is promoted by subsequent cohousing with a conspecific animal(s). This phenomenon has been termed housing-type social buffering. We previously found that social housing induced housing-type social buffering in fear-conditioned male rats. This buffering took the form of attenuated conditioned hyperthermia in response to an auditory conditioned stimulus (CS). Here, we assessed whether this social buffering is sustained even if the subject is housed alone after a period of social housing. When fear-conditioned subjects were housed alone during a 48-h period between conditioning and re-exposure to the auditory CS, they exhibited conditioned hyperthermia in response to the CS. However, conditioned hyperthermia was not observed when the 12-h period of social housing began 24 and 36h after conditioning during the 48-h period. This was not the case when the 12-h period of social housing began 0 and 12h after the conditioning. These results suggest that housing-type social buffering is sustained for 12h after the 12-h period of social housing. We next considered whether increasing the duration of social housing would extend the period of social buffering. We observed social buffering of conditioned hyperthermia 24 and 48, but not 96h after a 24-h period of social housing. These results suggest that social buffering was extended when the duration of social housing was increased. Taken together, our findings indicate that housing-type social buffering is sustained after a period of social housing. Copyright © 2016 Elsevier Inc. All rights reserved.

In recent years, many infrastructures have been deteriorating. In order to maintain sustainability of those infrastructures which have significant influence on social lifelines, economical and rational maintenance management should be carried out to evaluate the life cycle cost (LCC). The development of structural health monitoring systems, such as deriving evaluation techniques for the field structural condition of existing structures and identification techniques for the significant engineering properties of new structures, can be considered as the first step in resolving the above problem. New innovative evaluation methods need to be devised to identify the deterioration of infrastructures, e.g. steel tendons, cables in cable-stayed bridges and strands embedded in pre- or post-tensioned concrete structures. One of the possible solutions that show 'AtoE' characteristics, i.e., (a)ccuracy, (b)enefit, (c)ompendiousness, (d)urability and (e)ase of operation, elasto-magnetic (EM) actual stress sensory technology utilizing the sensitivity of incremental magnetic permeability to stress change, has been developed. Numerous verification tests on various steel materials have been conducted. By comparing with load cell, strain gage and other sensory technology measurement results, the actual stresses of steel tendons in a pre-stressed concrete structure at the following stages have been thoroughly investigated: (i) pre-stress change due to set-loss (anchorage slippage) at the tendon fixation stage; (ii) pre-stress change due to the tendon relaxation stage; (iii) concrete creep and shrinkage at the long term pre-stressing stage; (iv) pre-stress change in the cyclic fatigue loading stage; and (v) pre-stress change due to the re-pre-stress setting stage. As the result of this testing, it is confirmed that EM sensory technology enables one to measure actual stress in steel wire, strands and steel bars precisely without destroying the polyethylene covering sheath and enables

Tan, James Peng Lung; Cheong, Siew Siew Ann

2014-02-01

Complex systems are described by a large number of variables with strong and nonlinear interactions. Such systems frequently undergo regime shifts. Combining insights from bifurcation theory in nonlinear dynamics and the theory of critical transitions in statistical physics, we know that critical slowing down and critical fluctuations occur close to such regime shifts. In this paper, we show how universal precursors expected from such critical transitions can be used to forecast regime shifts in the US housing market. In the housing permit, volume of homes sold and percentage of homes sold for gain data, we detected strong early warning signals associated with a sequence of coupled regime shifts, starting from a Subprime Mortgage Loans transition in 2003-2004 and ending with the Subprime Crisis in 2007-2008. Weaker signals of critical slowing down were also detected in the US housing market data during the 1997-1998 Asian Financial Crisis and the 2000-2001 Technology Bubble Crisis. Backed by various macroeconomic data, we propose a scenario whereby hot money flowing back into the US during the Asian Financial Crisis fueled the Technology Bubble. When the Technology Bubble collapsed in 2000-2001, the hot money then flowed into the US housing market, triggering the Subprime Mortgage Loans transition in 2003-2004 and an ensuing sequence of transitions. We showed how this sequence of couple transitions unfolded in space and in time over the whole of US.

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

Fundamental Right to Property and Right to Housing in Nigeria: a Discourse

Directory of Open Access Journals (Sweden)

Akintunde OTUBU

2011-11-01

Full Text Available Housing is one of the basic needs of human kind. Given its quintessential relevance to the overall development of man and the State; the question is posed: whether there is a right to adequate housing in the citizen to warrant a demand from the State to fulfill this right; and whether there should be such a right? This paper sets out to examine the concept of Right as it relates to housing and enters into a discourse as to whether there is a fundamental right to housing under Nigeria law. A corollary to the above is to answer the question whether such a right should be cognizable under Nigerian law. In a doctrinal research approach, the paper concedes that housing is a prerequisite to optimal utility of man and the state. Unfortunately, right to housing does not enjoy the same ranking with civil and political rights for obvious reasons enunciated in the paper. The implication is that there is no enforceable right to housing under our law. Notwithstanding, the paper posits that it is desirable for the State to create an enabling environment for the realization of this right because of its multiplier effect on the individual and the State.

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

In our research project a suitable method has been developed related the technological aspect of the environmental assessment of land use changes caused by climate change. We have prepared an eco-balance (environmental inventory) to the environmental effects classification in life-cycle approach in connection with the typical agricultural / forest and tree utilization technologies. The use of balances and environmental classification makes possible to compare land-use technologies and their environmental effects per common functional unit. In order to test our environmental analysis model, we carried out surveys in sample of forest stands. We set up an eco-balance of the working systems of intermediate cutting and final harvest in the stands of beech, oak, spruce, acacia, poplar and short rotation energy plantations (willow, poplar). We set up the life-cycle plan of the surveyed working systems by using the GaBi 6.0 Professional software and carried out midpoint and endpoint impact assessment. Out of the results, we applied the values of CML 2001 - Global Warming Potential (GWP 100 years) [kg CO2-Equiv.] and Eco-Indicator 99 - Human health, Climate Change [DALY]. On the basis of the values we set up a ranking of technology. By this, we received the environmental impact classification of the technologies based on carbon footprint. The working systems had the greatest impact on global warming (GWP 100 years) throughout their whole life cycle. This is explained by the amount of carbon dioxide releasing to the atmosphere resulting from the fuel of the technologies. Abiotic depletion (ADP foss) and marine aquatic ecotoxicity (MAETP) emerged also as significant impact categories. These impact categories can be explained by the share of input of fuel and lube. On the basis of the most significant environmental impact category (carbon footprint), we perform the relative life cycle contribution and ranking of each technologies. The technological life cycle stages examined

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

2013-01-01

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

Science.gov (United States)

Hidayat, Benny; Afif, Zal

2017-11-01

Housing is the most affected sector by disasters as can be observed after the 2009 earthquake in West Sumatra province in Indonesia. As in Indonesian construction industry, the housing post-disaster reconstruction is influenced by knowledge and skills of builders or laborers, or locally known as `tukang'. After the earthquake there were trainings to transfer knowledge about earthquake-safe house structure for the builders in the post-disaster reconstruction. This study examined the effectiveness of the training in term of understanding of the builders and application of the new knowledge. Ten semi-structured interviews with the builders were conducted in this study. The results indicate that the builders with prior housing construction experience can absorb and understand the new knowledge about earthquake-safe house structure. Combination of lecturing and practice sessions also help the builders to understand the knowledge. However, findings of this research also suggest there is a problem in implementation of the new knowledge. Utilization of earthquake-safe house structure may leads to a rise in house cost. As a result, some house owners prefer to save money than to adopt the new knowledge.

Regulating technological change - The strategic reactions of utility companies towards subsidy policies in the German, Spanish and UK electricity markets

International Nuclear Information System (INIS)

Stenzel, Till; Frenzel, Alexander

2008-01-01

This paper focuses on how incumbent electric utilities strategically react to subsidy schemes supporting renewable energy technologies in the UK, Germany, and Spain. Firms coordinate the development of their technological capabilities and their political activities to shape their regulatory environment. Analysing the diffusion of wind power in these countries, we show that the different ways, in which firms coordinate their technological and political strategies, lead to very different market outcomes, both for the firms' market share and the size of the overall market. Although incumbents are usually seen as being resistant to change in energy systems, we show that Spanish utilities proactively drive the diffusion of wind power. We speculate about the relation between the ownership structure of the energy system and its inertia with respect to the integration of new technologies. We derive novel policy implications that explicitly take into account the strategic actions of incumbent firms shaping the technological and regulatory system

Dhruva is a product of technological initiatives taken during mid seventies when a need was felt for another research reactor having a high neutron flux to meet the growing demands of research and development in the frontier areas of science and engineering. In addition production of radioisotopes of high specific activity and the diverse requirements of a broad based user community had to be synthesized into a viable system, which could be engineered within the limited means available in the country. This high neutron flux reactor was designed, constructed and commissioned entirely by Indian scientists and engineers and it reflects the country's resolve to achieve self-reliance in the nuclear reactor technology. Dhruva is a 100 MW (thermal) research reactor with metallic natural uranium as fuel, heavy water as moderator, coolant and reflector, giving a maximum thermal neutron flux of 1.8 x 10{sup 14} n/cm{sup 2}/s. Since its first criticality on 8th August 1985, a number of experimental facilities have been added which have proven to be highly attractive for universities and industrial researchers for their scientific merits in various fields. One of the major utilization areas has been the neutron beam research using several neutron spectrometers, all of which were built in-house. A guide tube facility comprising of two neutron guides and another experimental set-up with a multi-instrument beam line have enabled further enhancement of the utilization of this National Facility by the academic institutions in the country. Production of radioisotopes of high specific activity and in increased quantity has fulfilled growing demands for many applications. The write-up provides an overview of the reactor covering its design; layout, safety features, utilization and operating experience along with description of some of the specific experimental facilities.

Science.gov (United States)

Mori, Takahiro; Asai, Hidehiro; Fukuda, Koichi; Matsukawa, Takashi

2018-04-01

A tunnel FET (TFET) is a candidate replacement for conventional MOSFETs to realize low-power LSI. The most significant issue with the practical application of TFETs concerns their low tunneling current. Si is an indirect-gap material with a low band-to-band tunneling probability and is not favored for the channel. However, a new technology has recently been proposed to enhance the tunneling current in Si-TFETs by utilizing isoelectronic trap (IET) technology. IET technology provides an innovative approach to realizing low-power LSI with TFETs. In this paper, state-of-the-art research on Si-TFETs with IET technology from the viewpoint of process and device integration is reviewed.

Utility Computing is not a new concept. It involves organizing and providing a wide range of computing-related services as public utilities. Much like water, gas, electricity and telecommunications, the concept of computing as public utility was announced in 1955. Utility Computing remained a concept for near 50 years. Now some models and forms of Utility Computing are emerging such as storage and server virtualization, grid computing, and automated provisioning. Recent trends in Utility Computing as a complex technology involve business procedures that could profoundly transform the nature of companies' IT services, organizational IT strategies and technology infrastructure, and business models. In the ultimate Utility Computing models, organizations will be able to acquire as much IT services as they need, whenever and wherever they need them. Based on networked businesses and new secure online applications, Utility Computing would facilitate "agility-integration" of IT resources and services within and between virtual companies. With the application of Utility Computing there could be concealment of the complexity of IT, reduction of operational expenses, and converting of IT costs to variable `on-demand' services. How far should technology, business and society go to adopt Utility Computing forms, modes and models?

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

2015-08-01

Full Text Available The study analyzes the influence of housing characteristics on rural migrants’ living condition in Beijing Fengtai District, China. The researcher will identify rural migrants in Beijing, examine their housing characteristics (housing crowding, housing privacy and housing facility and the influence on their living condition. Also, some suggestions are given to improve their housing characteristics and living condition. The government should revise the migrant housing policy and hukou management. Also, the rural migrants should try to increase their education level and social skills. For the occupation, the local government should give the rural migrants more job opportunity. These issues are analyzed in relation to local government attitudes toward the rural migrants. The analysis is based on data collected from two types of interviews: rural migrants and management interviews which examine the rural migrants’ housing and managerial aspects of this research, respectively. It is also supported by the utilization of secondary data. The findings of the study indicate that the rural migrants’ housing characteristics (housing crowding, housing privacy and housing facility highly influence their living condition in Beijing Fengtai District. Therefore, the local government should give some assistance to this group people in the big cities. This paper reports on the findings of a study to seek acknowledged definitions of the terms Project and Project Management. The study was based on a conventional review and analysis of the definitions from a series of texts.

The impact of housing policies and housing markets on ethnic spatial segregation

Andersen, Hans Skifter; Andersson, Roger; Wessel, Terje

2015-01-01

This paper examines how ethnic segregation is connected to an ethnic division of the housing market and a spatial separation of different housing tenures in four Nordic cities. Explanations for the differences across the cities are found by comparing housing markets and housing policies....... The housing markets are in all four cities ethnically segmented with high concentrations of immigrants in some forms of tenures (especially social/public housing) and low concentrations in others. We further discuss the reasons for the observed pattern. The paper shows that the spatial distribution...... housing, while co-operative housing is crucial in the fourth. It is also shown that a policy of neighbourhood tenure mix in one of the cities has resulted in a relatively low degree of segregation in spite of high concentrations of immigrants in social/public housing....

The requirements of the electric utility industry as the primary potential market for geothermal energy are analyzed, based on a series of structured interviews with utility companies and financial institution executives. The interviews were designed to determine what information and technologies would be required before utilities would make investment decisions in favor of geothermal energy, the time frame in which the information and technologies would have to be available, and the influence of the governmental politics. The paper describes the geothermal resources, electric utility industry, its structure, the forces influencing utility companies, and their relationship to geothermal energy. A strategy for federal stimulation of utility investment in geothermal energy is suggested. Possibilities are discussed for stimulating utility investment through financial incentives, amelioration of institutional barriers, and technological improvements.

All artificial systems and components in space degrade at higher rates than on Earth, depending in part on environmental conditions, design approach, assembly technologies, and the materials used. This degradation involves not only the hardware and software systems but the humans that interact with those systems. All technological functions and systems can be expressed through functional dependence: [Function]˜[ERU]∗[RUIS]∗[ISR]/[DR];where [ERU]efficiency (rate) of environmental resource utilization[RUIS]resource utilization infrastructure[ISR]in situ resources[DR]degradation rateThe limited resources of spaceflight and open space for autonomous missions require a high reliability (maximum possible, approaching 100%) for system functioning and operation, and must minimize the rate of any system degradation. To date, only a continuous human presence with a system in the spaceflight environment can absolutely mitigate those degradations. This mitigation is based on environmental amelioration for both the technology systems, as repair of data and spare parts, and the humans, as exercise and psychological support. Such maintenance now requires huge infrastructures, including research and development complexes and management agencies, which currently cannot move beyond the Earth. When considering what is required to move manned spaceflight from near Earth stations to remote locations such as Mars, what are the minimal technologies and infrastructures necessary for autonomous restoration of a degrading system in space? In all of the known system factors of a mission to Mars that reduce the mass load, increase the reliability, and reduce the mission’s overall risk, the current common denominator is the use of undeveloped or untested technologies. None of the technologies required to significantly reduce the risk for critical systems are currently available at acceptable readiness levels. Long term interplanetary missions require that space programs produce a craft

Strategies for spatial and technological flexibility

Directory of Open Access Journals (Sweden)

Cristiana Cellucci

2014-10-01

Full Text Available The design of housing sys- tems is today challenged by a highly uncertain context, dominated by the rapid development of functional and technological obsolescence in inherited housing models. The design of housing systems should first and foremost optimise the longevity of the sub-systems and be able to offset the process of obsolescence which is concomitant to both the current use of materials and components devised to fail after a short period, and to rigid spatial models that are incapable of adapting to changes in the household’s needs over time. This research examines flexibility as a fundamental requirement to be incorporated in the Life Cycle of the house, through the use of strategies that affect both the form and the technological system that governs its structure.

Pilot research project of risk communication on nuclear technology and its utilization. Toward communication and collaboration with community

Tsuchiya, Tomoko

2003-01-01

Although the importance of risk communication has been pointed out over the last decade in nuclear community, both public authorities and nuclear industry have not conducted the definite actions yet. It will be reflected in the public eye that nuclear community's attitude toward communication and consultation with the public about risk issues is half-hearted, comparing with chemical and food safety fields which recently launched their risk communication activities. In this study, we conduct risk communication experiments on some risk issues associated with nuclear technology and its utilization in Tokai village, for the purpose of establishment of risk communication in our society that might be one of the new relationships between science and technology and society. The outcomes of FY2002 study are the following threefold; 1) preparation of risk communication experiments on nuclear technology and its utilization, 2) assessment of social effects of risk communication activities, 3) preparation of practical guidebook for risk communication experiments.

Thuot, J.R.; Myron, H.; Gatrone, R.; McHenry, J.

1996-08-01

The projects were a series of pilot projects developed for DOE with the intention of transferring pollution prevention technology to private industry. The concept was to develop small technology transfer initiatives in partnership with the private sector. Argonne National Laboratory developed three projects: the microscale chemistry in education program, the microscale cost benefit study, and the Bethel New Life recycling trainee program. The two microscale chemistry projects focused on introducing microscale chemistry technologies to secondary and college education. These programs were inexpensive to develop and received excellent evaluations from participants and regulators. The recycle trainee project provided training for two participants and identified recycling and source reduction opportunities in Argonne`s solid waste stream. The pilot projects demonstrated that technology transfer initiatives can be developed and implemented with a small budget and within a short period of time. The essential components of the pilot projects were identification of target technologies that were already available, identification of target audiences, and a focus of effort to achieve a limited but defined objective.

Understanding of Danish passive houses based on pilot project Comfort Houses

Energy Technology Data Exchange (ETDEWEB)

Brunsgaard, C.

2010-12-15

The aim of the research is to investigate the notion of passive houses in Denmark. When this PhD thesis was initiated, the Danish building industry has just started to become interested in the passive house concept, but the knowledge was very limited. To be able to speed up the process of constructing Danish passive houses or other low energy concepts Saint-Gobain Isover Scandinavia took the initiative to the pilot project of the Comfort Houses, ten single-family houses constructed as passive houses, and wanted to share the knowledge with the building industry and other interested. This PhD thesis was a part of the strategy. If the concept of passive houses should be successfully promoted and achieve a significant sale in Denmark, it is believed that it is necessary to do a holistic approach. Besides energy savings and new structural solutions more qualitative aspects like architecture, everyday life and the future ways of living needs to be integrated in the future understanding of passive houses. This Ph.D. thesis therefore studies the following research question: What can the experience from the Comfort Houses enlighten about the future production and use of Danish passive houses? This understanding is achieved through studies of different study fields to be able to create a more holistic understanding of the concept both covering qualitative and quantitative analysis. The main focus will be on the study fields Design Process, Architecture and Everyday Life and the Indoor environment, which will answer the following sub-research questions: 1) How has the consortiums behind the Comfort Houses approached the design process according to teamwork, method and tools? And what barriers and possibilities lie within the approaches? 2) How do the occupants of the Comfort Houses experience the passive house architecture and the technical service systems? And has their everyday life changed by moving into a passive house? If so, how? 3) To what extent do the Comfort Houses

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

In recent years, radiation processing has emerged as an alternative to conventional technologies such as thermal and chemical processing for many industrial applications. The industry is expanding at a fast rate all over the world. The actual industrial benefits on commercial basis, however, depends on the need of the individual society and may vary from country to country. In India, the applications of radiation technology have been found in areas of health care, agriculture, food preservation, industry and environment. Both gamma radiation and electron beam accelerators are being utilized for this purpose. Presently, 6 commercial gamma irradiators housing about 1.5 million curie 60 Co and an annual turnover of over US$ 2 million and 3 commercial electron beam (EB) accelerators with installed capacity of 185 kW are commercially operating in India. The new areas being explored include use of electron beam irradiation for surface treatment, radiation processed membranes for a variety of applications and radiation processing of natural polymers. In the present paper, the current status of this program, especially the recent developments and future direction of radiation processing technology is reviewed. (author)

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

Science.gov (United States)

Dyb, Evelyn

2016-10-01

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

Full Text Available In the United States, two thirds of the carbon monoxide and about one third of carbon dioxide emissions come from the transportation sector. Ways to reduce these emissions in the future include replacing gasoline and diesel by biofuels, or by blend of biofuels with conventional gasoline and diesel, or by compressed natural gas (CNG, or by replacing internal combustion engines by electric motors powered by hydrogen fuel cells or battery-powered electric vehicles recharged from the electric grid. This presentation will review these technologies the fuel production pathways, when they are likely to be available, and by what fraction transportation sector green house gas emissions could be reduced by each. A well-to-wheels (WTW analysis is performed on each vehicle/ fuel technology using the GREET model and the total energy use, the CO 2 emissions, NO x emissions, SO x emissions for the life cycle of the vehicle technologies are calculated. Prospects for reducing foreign oil dependence as well as mitigating green house gases emission from the transportation sector will be considered in the analysis.

benefits. Because it produces hot water by extracting heat from the air it tends to dehumidify and cool the room in which it is placed. Moreover, it tends to spread the water heating load across utility non-peak periods. Thus, electric utilities with peak load issues could justify internal programs to promote this technology to residential and commercial customers. For practical purposes, consumers are indifferent to the manner in which water is heated but are very interested in product attributes such as initial first cost, operating cost, performance, serviceability, product size, and installation costs. Thus, the principal drivers for penetrating markets are demonstrating reliability, leveraging the dehumidification attributes of the HPWH, and creating programs that embrace life-cycle cost principles. To supplement this, a product warranty with scrupulous quality control should be implemented; first-price reduction through engineering, perhaps by reducing level of energy efficiency, should be pursued; and niche markets should be courted. The first step toward market penetration is to address the HPWH's performance reliability. Next, the manufacturers could engage select utilities to aggressively market the HPWH. A good approach would be to target distinct segments of the market with the potential for the highest benefits from the technology. Communications media that address performance issues should be developed. When marketing to new home builders, the HPWH could be introduced as part of an energy-efficient package offered as a standard feature by builders of new homes within a community. Conducting focus groups across the United States to gather input on HPWH consumer values will feed useful data back to the manufacturers. ''Renaming'' and ''repackaging'' the HPWH to improve consumer perception, appliance aesthetics, and name recognition should be considered. Once an increased sales volume is achieved, the manufacturers

Specific Consideration on Superior Performance and Evaluation Methods of Polymer-housed Surge Arresters

Science.gov (United States)

Ishizaki, Yoshihiro; Kobayashi, Misao; Suzuki, Hironori; Futagami, Koichi

It is very suitable to select the polymer materials for the housings of surge arresters (SAs), because the polymer materials are generally soft and light weight. Therefore, many kinds of polymer-housed SAs using various polymer materials have been developed, and expanding into many countries. Considering these backgrounds, the JEC technical report (JEC-TR) 23002-2008; polymer-housed surge arrester(1) has been established based on the existent relevant standards of arresters, such as JEC-2371-2003; Insulator-housed surge arresters(2) and IEC 60099-4 Edition 2.2, Metal-oxide surge arresters (MOSAs) without gaps for a.c. systems(3) in order to introduce the technology and provide a common guide for testing of polymer-housed SAs. According as the JEC-TR, the various new applications of the polymer-housed SAs, which are caused by superior advantages such as compact, light weight, safe failure mode, anti-seismic performance, anti-pollution performance and cost efficiency design, have been realized recently in Japan. Therefore, this paper gives specific consideration on the superior performance of the polymer-housed SAs and the evaluation methods of the polymer-housed SAs, because there are some issues in the existent standards to be solved.

Housing and Quality of Life for Migrant Communities in Western Europe: A Capabilities Approach

Directory of Open Access Journals (Sweden)

Dermot Coates

2013-12-01

Full Text Available Housing is an important determinant of quality of life and migrants are more likely to encounter poor quality housing than natives. This paper draws on the capabilities approach to welfare economics to examine how issues of housing and neighborhood conditions influence quality of life and opportunities for migrants in Western Europe. The analysis utilizes data from the second European Quality of Life Survey (EQLS to explore variation in life and housing satisfaction between migrants and non-migrants (natives in Western Europe and whether being a migrant and living in an ethnically diverse neighborhood contribute to lower satisfaction. The results show that migrants are more likely to experience lower levels of life and housing satisfaction and that living in a diverse neighborhood is negatively associated with life and housing satisfaction. While diverse, inner-city neighborhoods can increase opportunities for labor market access, social services and integration, the tendency towards clustered settlement by migrants can also compound housing inequality. Conversely, migrant homeowners are on average substantially more satisfied with the quality of public services and of their neighborhood and have lower material deprivation than both migrant and non-migrant renters. The findings draw attention to the need to address housing and neighborhood conditions in order to improve opportunities for integration and well-being. 

Livable Housing Design: The voluntary provision of inclusive housing in Australia

Directory of Open Access Journals (Sweden)

Margaret Louise Ward

2014-06-01

Full Text Available This paper reports on a study of the voluntary provision of inclusive housing. The impetus for the study is the Livable Housing Design initiative, an agreement among Australian housing industry and community leaders in 2010 to a national guideline and voluntary strategy with a target to provide minimum access features in all new housing by 2020. Situated in and around Brisbane, Australia, the study problematises the assumption that the housing industry will respond voluntarily; an assumption which this study concludes is unfounded. The Livable Housing Design initiative asks individual agents to consider the needs of people beyond the initial contract, to proceed with objective reasoning and to do the right thing voluntarily. Instead, the study found that interviewees focused on their immediate contractual obligations, were reluctant to change established practices and saw little reason to do more than was legally required of them. This paper argues that the highly-competitive and risk-averse nature of the industry works against a voluntary approach for inclusive housing and, if the 2020 target of the Livable Housing Design.

Full Text Available The aim of this study is to measure the technical efficiency of housing construction in Iran and also to define current status of the housing industry system and its future in the country. Data Envelopment Analysis (DEA and the input based model of CCR with fixed return to scale have been used to evaluate housing industry performance in different states of Iran during the years 2006-2009. The complementary BCC approach with assumption of variable return to scale has been used for dividing technical efficiency to management and scale efficiencies. The findings imply that the average efficiency score obtained by all the states is 0.94 and only 37 percent of the states operate technically efficient. On the other hand, about 63 percent of the states are found as relatively inefficient and mostly present decreasing return to scale. Also, it has been found that the inefficient states have management inefficiency in utilizing construction inputs. Without any doubt, managerial and supportive assistance of the government to inefficient states, motivating construction employees to proper jobs and knowledge development in optimum assignment of construction factors could be appropriate solutions for the problems of the housing sector.

Research on interventions to positively impact health and housing status of people who are homeless has received substantially increased attention over the past 5 years. This rapid review examines recent evidence regarding interventions that have been shown to improve the health of homeless people, with particular focus on the effect of these interventions on housing status. A total of 1,546 articles were identified by a structured search of five electronic databases, a hand search of grey literature and relevant journals, and contact with experts. Two reviewers independently screened the first 10% of titles and abstracts for relevance. Inter-rater reliability was high and as a result only one reviewer screened the remaining titles and abstracts. Articles were included if they were published between January 2004 and December 2009 and examined the effectiveness of an intervention to improve the health or healthcare utilization of people who were homeless, marginally housed, or at risk of homelessness. Two reviewers independently scored all relevant articles for quality. Eighty-four relevant studies were identified; none were of strong quality while ten were rated of moderate quality. For homeless people with mental illness, provision of housing upon hospital discharge was effective in improving sustained housing. For homeless people with substance abuse issues or concurrent disorders, provision of housing was associated with decreased substance use, relapses from periods of substance abstinence, and health services utilization, and increased housing tenure. Abstinent dependent housing was more effective in supporting housing status, substance abstinence, and improved psychiatric outcomes than non-abstinence dependent housing or no housing. Provision of housing also improved health outcomes among homeless populations with HIV. Health promotion programs can decrease risk behaviours among homeless populations.

Yugoslavian Modernist Architecture, although part of a larger cultural phenomenon, received hardly any international attention, since there are only a few internationally published studies about it. Nevertheless, Modernist Architecture of the Inter-war Yugoslavia (Kingdom of Yugoslavia), and specially Modernist Architecture of the Post-war Yugoslavia (Socialist Federal Republic of Yugoslavia under the “reign” of Tito), represents the most important architectural heritage of the 20th century in former Yugoslavian countries. Belgrade, as the capital city of both newly founded Yugoslavia(s), experienced an immediate economic, political and cultural expansion after the both wars, as well as a large population increase. The construction of sufficient and appropriate new housing was a major undertaking in both periods (1919-1940 and 1948-1980), however conceived and realized with deeply diverging views. The transition from villas and modest apartment buildings, as main housing typologies in the Inter-war period, to the mass housing of the Post-war period, was not only a result of the different socio-political context of the two Yugoslavia(s), but also the country’s industrialization, modernization and technological development. Through the classification of Modernist housing buildings in Belgrade, this paper will investigate on relations between the transformations of the main housing typologies executed under different socio-political contexts on the one side, and development of building technologies, construction systems and materials applied on those buildings on the other side. The paper wants to shed light on the Yugoslavian Modernist Architecture in order to increase the international awareness on its architectural and heritage values. The aim is an integrated re-evaluation of the buildings, presentation of their current condition and potentials for future (re)use with a specific focus on building envelopes and construction.

Objective: Our home can have a major impact on our physical and mental health; this is particularly true for older people who may spend more time at home. Older people in social (i.e., public) housing are particularly vulnerable. Housing options for older people in social housing include standard design dwellings or specially designed "sheltered housing." The most suitable housing model should be identified, with older people consulted in this process. Method: Survey of older people (aged ≥60) living in standard or sheltered social housing. Data were analyzed using descriptive and inferential statistics in SPSS Version 22. Results: Overall, 380 surveys were returned (response rate = 47.2%). All older people had similar housing needs. Those in sheltered housing were more satisfied with the physical home design and reported more positive outcomes. Older people in standard housing were less likely to have necessary adaptations to facilitate aging-in-place. Discussion: Older people in standard housing reported more disability/illnesses, are worried about the future, and felt less safe at home. However, few wanted to move, and very few viewed sheltered housing as an alternative, suggesting limited knowledge about their housing options. Future social housing designs should be flexible, that is, adaptable to the needs of the tenants over time.

This paper introduces the first commercially available polymer enclosed intermediate class metal oxide surge arrester. It describes the unique construction of the design, including reduced size, increased flexibility, a collared seal on the polymer housing and an open webbed fiberglass-epoxy module which houses the metal oxide disc elements. Performance advantages are discussed. These include improved short term contamination performance of the insulator-like polymer design when compared to multi-unit porcelain housed designs. Data will show that polymer housed open-webbed fiberglass module construction extends the pressure relief capability beyond that of typical porcelain enclosed designs. The capability of the polymer enclosed design to withstand repeated pressure relief tests, simulating system reclose on a failed arrester, is also discussed. This paper discusses the circumstances at one utility which has considered utilizing polymer enclosed intermediate class arresters to effectively upgrade their system protection capabilities

Full Text Available The paper covers the issues of market members’ social responsibilities when a particular economic sector is being reformed, house and public utility sphere being an example of such sector. The author conceives both the prerequisites for sustainable development of an economic sector (utility sphere being an example and issues concerning consumer protection system that is to eliminate rendering of nonconforming services as well as supplier protection system aimed against non-payers. The paper considers social and economic practices that were systematized after their content had been modified in a way. The author analyzes the factors that are significant for both the process of building up an entity’s profile and employees, provided the specific characteristics of house and public utility sphere have been taken in consideration. The author’s conclusion is that in this case citizens become more aware of house and public utility sphere social practices. As a result, social awareness of such practices gets enhanced. The methodological method can be applied to study the issue.The scientific aim of the paper is to consider and establish grounds of social practices when a particular economic sector is being reformed and institutional relations are being transformed.The technique of the work performed is based criterion identification that might contribute to establishing a basis of various house and public utility services.In order to get the results a group of theoretical and empirical methods have been resorted to: analysis, synthesis, dialectical method that both showed inconsistency and variability of social and economic processes and juxtaposed the similarities and differences; comparative method, monitoring and method of diagrams.          The results of the work performed can be defined as the prerequisites for sustainable development of both house and public utility sphere and entities’ social and economic

Space Resource Utilization: Technologies and Potential Synergism with Terrestrial Mining

Space Resources and Their Uses: The idea of using resources in space to support human exploration and settlement or for economic development and profit beyond the surface of Earth has been proposed and discussed for decades. Work on developing a method to extract oxygen from lunar regolith started even before humans set foot on the Moon for the first time. The use of space resources, commonly referred to as In Situ Resource Utilization (ISRU), involves the processes and operations to harness and utilize resources in space (both natural and discarded) to create products for subsequent use. Potential space resources include water, solar wind implanted volatiles (hydrogen, helium, carbon, nitrogen, etc.), vast quantities of metals and minerals in extraterrestrial soils, atmospheric constituents, unlimited solar energy, regions of permanent light and darkness, the vacuum and zero-gravity of space itself, trash and waste from human crew activities, and discarded hardware that has completed its primary purpose. ISRU covers a wide variety of concepts, technical disciplines, technologies, and processes. When considering all aspects of ISRU, there are 5 main areas that are relevant to human space exploration and the commercialization of space: 1. Resource Characterization and Mapping, 2. In Situ Consumables Production, 3. Civil Engineering and Construction, 4. In Situ Energy Production and Storage, and 5. In Situ Manufacturing.

Effect of regulation on the rate of adoption of cost saving scale technology in the electric utility industry: a portfolio approach

International Nuclear Information System (INIS)

Scheraga, C.A.

1984-01-01

This study presents a new analytical framework for examining the relationship between regulation and the investment behavior of electric utilities. The particular kind of investment behavior considered is the adoption of new as well as innovative electrical generation technology. The technologies of interest are large scale coal and nuclear generation plants. The theoretical model used in this study differs from traditional approaches in its utilization of a behavioral framework of analysis. The responsiveness of utilities to the required rate of return demanded by stockholders is demonstrated using an augmented form of the standard Capital Asset Pricing Model. Regulation is viewed as affecting utility investment behavior through the effect of the actions of regulatory commissions on the required rate of return that utilities must earn on equity. The particular regulatory policies considered are modification of existing rate structure, automatic adjustment clauses, and required efficiency standards. These policies are of particular interest both because their effects have not been previously examined in detail, and because they are recommended for adoption in the Public Utility Regulatory Policies Act of 1978. It is demonstrated empirically that the above policies do affect the required rate of return for utilities and hence their innovative investment behavior

Developing and Evaluating a Virtual Reality-Based Navigation System for Pre-Sale Housing Sales

Full Text Available Virtual reality (VR technologies have advanced rapidly in the past few years, and many industries have adopted these cutting-edge technologies for diverse applications to improve their industrial competitiveness. VR has also received considerable recognition in the architecture, engineering, and construction industries, because it can potentially reduce project costs, delivery time, and quality risks, by allowing users to experience unbuilt spaces before breaking ground, resolving construction conflicts virtually, and reviewing complex details in immersive environments. In the real estate market, VR can also play an important role in affecting buyers’ housing purchasing decisions, especially for housing markets in Asia, where the pre-sale system is extremely common. Applying VR to the pre-sale housing system is promising, because the concept of pre-sale refers to a strategy adopted by developers that sell housing through agreements on residential units that have not been constructed yet, and VR at this stage could be a useful tool for visual communication in a true-to-scale environment. However, does VR really benefit sales in the housing market? Can clients accept using VR, instead of using traditional materials (i.e., paper-based images and physical models, to navigate and experience housing projects? The objective of this study is to develop a VR-based navigation system for a pre-sale housing project in Taiwan. We invited 30 potential clients to test the system and explore the implications of using it for project navigation. The results reveal that VR enhances the understandings of a project (perceived usefulness and increases clients’ intention to purchase, while the operation of VR (perceived ease-of-use is still the major challenge to affect clients’ satisfaction and the developer’s acceptance with respect to applying it to future housing sales.
