    Full Text Available Within his large architectural production, Frank Lloyd Wright had the opportunity to experiment with the timber industrialization, linking a traditional material with the modern sense of architecture. Wood and Frank Lloyd Wright are inseparable from the balloon frame system, a system which he will use at his first housing and through which he will materialize the spatial decomposition concept. The research on the particular American System-Built Houses case will serve to show the earliest experiences of Wright with the industry, whose conclusions he would use for subsequent researches on prefabrication.

    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.

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

    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.

    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.

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

    Enterprise Resource Planning systems are the combination of different business IS (Information System) applications that are designed according to the organization requirements. Generally ERP systems are suffering from complex user interface issues. Recent research shows that there is a need for improvement concerning, the user interface from their perspectives. In order to design the software applications that are easy to use, memorize and apply to new problems, we must know the users philosophy and something about learning, reminiscence and problems solving. The Usability engineering is the only way to study the deeds of users while interacting with ERP (Enterprise Resource & Planning). This paper will focus on the users' experiences view of financial module in ERP system. The HCI research method, explicitly survey questionnaire method was adopted to gather users understanding in order to evaluate the selected modules for in-housed ERP system. The study involved group of users from two industries, the results can not be generalized as a whole. The study was first time successfully applied Usability evaluation on in-housed ERP in local industry (Masood Textile Mills, Interloop Ltd) in Pakistan. The results may hopefully opened-up an area of research and methodology that could provide considerable further benefits to Industry in developments of Industrial information systems.

    Full Text Available Much has been written on Off-site Manufacturing (OSM in construction, particularly regarding the perceived benefits and barriers to implementation. However, there seems to be a wide misunderstanding of the state of OSM associated with the concept of decision by many of those involved in decision making process within the house building industry. This has led to a demand for guidance’s on decision making process for construction project leaders particularly at early project stages. Choosing a construction method for a project will require an optimum decision strategy which involves careful understanding, measurement and evaluation of a number of decision factors that can have the most influence on successful decision action. This paper, therefore, aims to identify the key decision factors to be considered at evaluation stage when choosing to use Off-Site Manufacturing (OSM as a construction strategy in house building projects. This will reveal the key drivers for change in the industry towards the use of OSM in house building.

Para ello, Entenza diseñó una novedosa estrategia de colaboración entre algunos de los mejores arquitectos californianos del momento y la maquinaria industrial estadounidense, abierta a un proceso de reconversión de producción bélica a objetos para la población civil que tendría lugar en un tiempo récord. Así, el artículo propone el análisis de esa relación entre empresa y domesticidad, entre viabilidad económica y calidad arquitectónica, entre procesos de prefabricación y espíritu individual. Todos ellos conceptos aparentemente opuestos pero que, de la mano del programa Case Study House, lograron un entendimiento que a día de hoy sigue resultando extraordinario. SUMMARY In January 1945, John Entenza, editor of the California Arts & Architecture magazine, launched the ‘Case Study House Program’, an ambitious project whose firm objective was to investigate the possibilities and solutions for the housing problem facing the United States after the war. To do this, Entenza designed a novel strategy for collaboration between some of the best Californian architects of the time and the U.S. industrial machine, open to a process of conversion from military production to objects for the civilian population that would take place in record time. Thus, the article proposes the analysis of the relationship between business and domesticity, between economic viability and architectural quality, between prefabrication processes and individual spirit. All of these seemingly opposing concepts reached, at the hands of the ‘Case Study House Program’, an understanding that still seems extraordinary today.

    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.

    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.

    During the Twelve Five period, China promulgated industrial policies promote the energy-intensive industries relocate to coastal areas in order to utilize marine shipping resources. Consequently, some major state-owned steel and petrochemical enterprises have relocated and resulted in a large scale coastal area development. Restricted by the port construction, most of the coastal industrial areas are located in the outer suburbs. To balance between employment and housing, new industrial coastal towns were constructed. In this paper, we adopt a case-study approach to analysis some typical industrial coastal towns of Liaoning Province situated in the Bohai Bay, which is currently under rapid economic growth. Our investigations reflect the common phenomenon of long distance commuting and massive amount of vacant residences. More specifically, large plant relocation caused hundreds of kilometers of daily commute and enterprises had to provide housing subsidies and education incentives to motivate employees to relocate to coastal areas. Nonetheless, many employees still refuse to relocate due to job stability, diverse needs of family members and access to convenient services. These employees averaged 4 hours of commute daily and some who lived further had to reside in temporary industrial housing units and subject to long-term family separation. As a result, only a small portion of employees purchase new coastal residences but mostly for investment and retirement purposes, leading to massive vacancy and ghost-town phenomenon. In contrast to the low demand, coastal areas tend to develop large amount of residences prior to industrial relocation, which may be directly related to local government finances. Some local governments have sold residential land to developers to general revenue to support the subsequent industrial development. Subject to the strong preference of ocean- view, residential housing developers tend to select coast-line land to construct new residential

Research field is massive housing up to 23 floors, 400 dwellings per building and different housing layouts—to be evaluated for potential retrofitting at the dwelling level. IBM for massive housing built with IMS construction technology represents an integration of systems’ components into hierarchy assemblies by simple joints. IMS Building Technology by IMS Institute is the system for high-rise structures with prefabricated elements of the skeleton. In order to assess the current situation regarding the selection and implementation of energy savings measures and the role of industrialized technology in supporting the rehabilitation of post-war housing in Belgrade—building configuration model and IMS construction technology has been analyzed, providing in-depth information on the way building components and systems are put together into IBM. In which way retrofit may be approached? IBM is represented with graph model (GM diagram to describe a number of value-added processes according to independent systems/components and flexible connections. This paper highlights the technological aspects of “open” prefabrication industry and building with the systems that should be assessed in the future retrofitting of massive housing based on industrialization and energy efficiency. The paper proposes an IBM that provides concrete description of massive housing buildings, the requirements for information to be provided to approving refurbishment processes. The research also addresses both: challenges as well as opportunities for advancing Building Information Modeling (BIM standards in off-site re-construction of massive housing with new “infill” industry.

    Full Text Available The overall aim of the research presented is to investigate the relationship between the macroeconomic factors linked with financial crises and housing industry in Turkey. The research includes empirical investigation in a regression based model using mostly the Turkish market data. The ability of public intervention, indicated by central bank reserves and corporate bankruptcies are statistically effective in the performance of housing market. There is weak statistical dependence of housing on financial crisis. The research is based on Turkish market data between the period 2002-2009. The research can be extended with global market data especially from the emerging market for a comparative study. Research in this field should focus more to industry dynamics rather than macroeceonomic variables explaining crisis to explore housing sector dynamics. The real estate managers should look to central bank reserves and corporate bankruptcies more closely as a macroeceonomic variable affecting housing industry. The effect of macroeceonomic variables in the period of financial volatility is limited in the housing market, whereas industry factors should be analized. Central bank reserves and corporate bankruptcies are important indicators of housing industry growth that can be used as an instrument. To to the author’s knowledge, the paper is the first study to investigate the link between financial crisis and housing market in Turkey.

    The energy consumption and greenhouse gas emission by the residential housing sector are considered to be one of the largest in economically developed countries. The larger energy consumption and greenhouse gas emission not only put additional pressure on finite fossil fuel resources but also cause global warming and climate change. Additionally, the residential housing sector will be consuming more energy as the house demand and average house floor area are progressively increasing. With currently used residential house wall systems, it is hard to reduce energy consumption for ongoing house space heating and cooling. A smart house wall envelope with optimal thermal masses and insulation materials is vital for reducing our increasing energy consumption. The major aim of this study is to investigate thermal performance and energy saving potential of a new house wall system for variable climate conditions. The thermal performance modelling was carried out using commercially developed software AccuRate ® . The findings indicate that a notable energy savings can be accomplished if a smart house wall system is used. -- Highlights: • Smart house wall system. • Thermal performance modelling and star energy rating. • Energy savings and greenhouse gas reduction

    There is a global move from individual to group housing of gestating sows. In the European Union, individual gestating stalls will be banned by 2013. Just like in other industrialized regions, these stalls have been the standard housing system for intensively kept sows from the 1960s onward in the Flemish region of Belgium. Because the socioeconomic consequences for the pig industry may be far-reaching and because farmer attitude may influence the realization of the hoped-for improvement in animal welfare in practice, we conducted a survey from 2003 until 2009 among representative samples of Flemish pig producers every 2 yr. The share of farms with group housing increased from 10.5% in 2003 to 29.8% in 2007, but then dropped to 24.6% in 2009. It appears that after 2005 users of old group housing systems in particular stopped farming. Because sow herd size increased more on farms with vs. without group housing and because the proportion of the herd that was group-housed also tended to increase between 2003 to 2009, the change to group housing took place faster when expressed at the level of the sow (from 9.1% in 2003 to 34.1% in 2009) instead of farm. The percentage of farmers planning to convert to group housing within 2 yr was 4.1% in 2003, and 6 to 7% thereafter. These were typically young farmers (P = 0.006) with a large sow herd (P manual feed delivery. User satisfaction was generally high but depended on whether or not all gestating sows were kept in group (P importance of economic reasons (P = 0.007) and type of labor (P = 0.043) decreased with the age of the system. In 2003 and 2005 the main reason for not having converted to group housing was that farmers would stop keeping sows by 2013. In 2007 and 2009 the reasons mainly concerned uncertainty about the future and maximally delaying the conversion. Belgium is one of the European Union countries where the pig industry is expected to undergo drastic changes during the few years remaining before the ban on

    Full Text Available In this research work we will present the architecture of an intelligent house system capable to detect accidents cause by floods, gas, and to protect against unauthorized access or burglary. Our system is not just an alarm, it continuously monitors the house and reports over internet its state. Most of the current smart house systems available on the market alarms the user via email or SMS when an unwanted event happens. Thus, the user assumes that the house is not affected if an alarm message is not received. This is not always true, since the monitoring system components can also damage, or the entire system can become unable to send an alarm message even if it detects an unwanted event. This article presents also details about both hardware and software implementation.

    An unparalleled number between housing demand and housing supply in Malaysia has increased the housing prices, which gives consequences to the homeownership issue. One way to reduce the housing price is by faster increase the number of affordable housing, but the construction sector faces difficulties in delivering as expected number by using conventional and current industrialised building system (IBS) due to the issue related high project cost, time and labour. Therefore, light steel housing (LSH) system as one of another type of IBS method can be utilised in housing construction project. This method can replace the conventional method that was currently used in the construction of affordable housing project. The objectives of this study are to identify the potential of LSH and influencing factors of system implementation. This is an initial stage to review the previous study related to LSH implementation in developed and developing countries. The previous study will be analysed regarding advantages and disadvantages of LSH and factors that influence the implementation of the system. Based on the literature review it is expected to define the potential and influencing factors of the LSH system. The findings are meaningful in framing and enhance construction housing method of an affordable housing project in Malaysia.

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

    Industrial applications of a control system package have extended from industrial research to process control. While the requirements of these applications have much in common with accelerator controls, there are always extensions, different emphases, and additional requirements. These often add to the applicability of the software in all fields and certainly keep the development team challenged. This paper discusses some of the influences that industrial applications such as power distribution monitoring, casting and rolling mills, and aircraft engine testing have on software originally designed for scientific research. We also discuss some of the differences in the software development process between development for in-house use and development for sales and industrial use. (Author) ref., fig

    The strategies for housing zebrafish used in biomedical research have evolved considerably over the past three decades. To keep pace with the rapid expansion and development of the zebrafish model system, the field has generally moved from keeping fish at the level of aquarium hobbyist to that of industrialized, recirculating aquaculture. Numerous commercial system vendors now offer increasingly sophisticated housing systems based on design principles that maximize the number of animals that can be housed in a given space footprint, and they are thus able to support large and diverse research programs. This review is designed to provide managers, lab animal veterinarians, investigators, and other parties responsible for care and use of these animals with a comprehensive overview of the basic operating and design principles of zebrafish housing systems. This information can be used to help plan the construction of new facilities and/or the upgrade and maintenance of existing operations.

    Energy has always been a strategic component of Air Products and Chemicals production costs. In fact, Air Products is among the top consumers of electricity and natural gas in the U.S. Consequently, Air Products has developed a multifaceted Corporate Energy Department. The advent of PURPA in 1978 and the success enjoyed by Air Products in selling industrial gases over the fence to industrial customers as a integral part of their manufacturing system led Air Products into the industrial cogeneration business. This paper briefly summarizes Air Products entry into the industrial cogeneration market and the role that Air Products Energy Department has played in making this new business focus a success. It highlights how Air Products has been able to transfer its in-house expertise in purchasing power to the marketing, bidding, contract negotiation and avoided cost forecasting functions so critical in the successful development of industrial cogeneration opportunities. At Air Products we believe our long association with the utility industry first as a cost-conscious customer and more recently as an electric energy supplier has enhanced our competitive position. The same success story could be repeated at your company if you know what to look for and are not afraid to expand the horizons and responsibilities of your energy department

    The environment in the broiler house is a combination of physical and biological factors generating a complex dynamic system of interactions between birds, husbandry system, light, temperature, and the aerial environment. Ventilation plays a key role in this scenario. It is pivotal to remove carbon dioxide and water vapor from the air of the hen house. Adequate ventilation rates provide the most effective method of controlling temperature within the hen house. They allow for controlling the relative humidity and can play a key role in alleviating the negative effects of high stocking density and of wet litter. In the present study the results of experimental tests performed in a breeding broiler farm are shown. In particular the efficiency of a semi transversal ventilation system was studied against the use of a pure transversal one. In order to verify the efficiency of the systems, fluid dynamic simulations were carried out using the software Comsol multiphysics. The results of this study show that a correct architectural and structural design of the building must be supported by a design of the ventilation system able to maintain the environmental parameters within the limits of the thermo‑neutral and welfare conditions and to achieve the highest levels of productivity.

    Air barrier systems used in modern Canadian airtight homes were discussed. The Advanced Houses Program sets its airtightness requirements at 1.5 air changes per hour at 50 Pascals pressure difference (ACH{sub 5}0). In recent tests of 10 houses, it was suggested that a better airtightness level was attainable with average airtightness of about 1.0 ACH{sub 5}0. Six of the homes tested did not use the traditional polyethylene approach. Two of the houses used the airtight drywall approach, one used a foam system, and three used exterior air barriers. The advantages and disadvantages of each system was described, including cost effectiveness, cost reduction, performance and installation advantages. The confusion between an air barrier and a vapour diffusion retarder was explained. Exterior air barriers showed the greatest potential for meeting airtightness requirements at reasonable cost. 5 refs., 3 tabs.

    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.

  18. Industrial ecology: a new perspective on the future of the industrial system.

    Science.gov (United States)

    Erkman, S

    2001-09-22

    Industrial ecology? A surprising, intriguing expression that immediately draws our attention. The spontaneous reaction is that "industrial ecology" is a contradiction in terms, something of an oxymoron, like "obscure clarity" or "burning ice". Why this reflex? Probably because we are accustomed to considering the industrial system as isolated from the Biosphere, with factories and cities on one side and nature on the other, as well as the recurrent problem of trying to minimise th impact of the industrial system on what is "beyond" it: its surroundings, the "environment". As early as the 1950's, this end-of-pipe angle was the one adopted by ecologists, whose first serious studies focused on the consequences of the various forms of pollution on nature. In this perspective on the industrial system, human industrial activity as such remained outside the field of research. Industrial ecology explores the opposite assumption: The industrial system can be seen as a certain kind of ecosystem. After all, the industrial system, just as natural ecosystems, can be described as a particular distribution of materials, energy, and information flows. Furthermore, the entire industrial system relies on resources and services provided by the Biosphere, from which it cannot be dissociated. (It should be specified that "industrial", in the context of industrial ecology, refers to all human activities occurring within modern technological society. Thus, tourism, housing, medical services, transportation, agriculture, etc. are part of the industrial system.) Besides its rigorous scientific conceptual framework (scientific ecology), industrial ecology can also be seen as a practical approach to sustainability. It is an attempt to address the question, "How can the concept of sustainable development be made operational in an economically feasible way?" Industrial ecology represents precisely one of the paths that could provide concrete solutions. Governments have traditionally approached

    2015-09-01

    Full Text Available A comparative analysis of the costs related to the construction of low-rise, low-cost and social welfare housing was carried out. The study included three of the most commonly used structural systems for low-rise housing in Latin America, such as the traditional system of confined masonry walls, concrete walls conventionally reinforced with welded-wire meshes and concrete walls reinforced with steel fiber. The cost comparison was carried out by budgets analysis, which were performed based on construction quantities, unit prices and particular items for each structural system. It was found in the study that, from an economic point of view, the systems of concrete walls reinforced with welded-wire meshes or steel fibers are more advantageous than confined masonry systems. In addition, the integral comparison of the three structural systems demonstrates that the industrialized system of steel fiber reinforced concrete walls allows obtaining greater advantages of cleaning and sustainability, faster construction, lower cost and a more attractive scenario for builders investing in such projects.

  3. The Butterfly House Industry: Conservation Risks and Education Opportunities

    Directory of Open Access Journals (Sweden)

    Michael Boppré

    2012-01-01

    Full Text Available This paper addresses the mass supply and use of butterflies for live exhibits, discusses the risks to biodiversity which this creates, and the educational opportunities it presents. Over the past 30 years a new type of insect zoo has become popular worldwide: the butterfly house. This has given rise to the global Butterfly House Industry (BHI based on the mass production of butterfly pupae as a cash crop. Production is largely carried out by privately-owned butterfly farms in tropical countries, notably Central America and Southeast Asia. Most pupae are exported to North America and Europe, although the number of butterfly houses in tropical countries is growing. The BHI is described with respect to its stakeholders, their diverse interests, and its extent. It is estimated that the global turnover of the BHI is in the order of USD 100 million. From a conservation perspective, there is a tension between risks and benefits. The risks to biodiversity are primarily unsustainable production, potential bastardisation of local faunas and floras, and genetic mixing within and even between butterfly species. This paper discusses general ways of managing these risks. Ethical concerns range from fair trade issues to animal husbandry and the use of wildlife for entertainment. For the risks to biodiversity and unresolved ethical issues to be tolerable, the BHI needs to make a significant contribution to conservation, primarily through effective education about butterfly biology as a means to raise public awareness of basic ecological processes, and conservation and environmental issues. It should also engage with local conservation initiatives. Currently the BHI′s great potential for public good in these respects is rarely realised. The paper concludes by looking at the special nature of the BHI, and its need for effective self-regulation if it is to continue to escape from public scrutiny and the introduction of restrictive regulations. The BHI needs to

  4. High Power UV LED Industrial Curing Systems

    2012-05-14

    UV curing is a green technology that is largely underutilized because UV radiation sources like Hg Lamps are unreliable and difficult to use. High Power UV LEDs are now efficient enough to replace Hg Lamps, and offer significantly improved performance relative to Hg Lamps. In this study, a modular, scalable high power UV LED curing system was designed and tested, performing well in industrial coating evaluations. In order to achieve mechanical form factors similar to commercial Hg Lamp systems, a new patent pending design was employed enabling high irradiance at long working distances. While high power UV LEDs are currently only available at longer UVA wavelengths, rapid progress on UVC LEDs and the development of new formulations designed specifically for use with UV LED sources will converge to drive more rapid adoption of UV curing technology. An assessment of the environmental impact of replacing Hg Lamp systems with UV LED systems was performed. Since UV curing is used in only a small portion of the industrial printing, painting and coating markets, the ease of use of UV LED systems should increase the use of UV curing technology. Even a small penetration of the significant number of industrial applications still using oven curing and drying will lead to significant reductions in energy consumption and reductions in the emission of green house gases and solvent emissions.

    This article reports the first publicly available egg production costs compared across 3 hen-housing systems. We collected detailed data from 2 flock cycles from a commercial egg farm operating a conventional barn, an aviary, and an enriched colony system at the same location. The farm employed the same operational and accounting procedures for each housing system. Results provide clear evidence that egg production costs are much higher for the aviary system than the other 2 housing systems. Feed costs per dozen eggs are somewhat higher for the aviary and lower for the enriched house compared with the conventional house. Labor costs are much lower for the conventional house than the other 2, and pullet costs are much higher for the aviary. Energy and miscellaneous costs are a minimal part of total operating costs and do not differ by housing system. Total capital investments per hen-capacity are much higher for the aviary and the enriched house. Capital costs per dozen eggs depend on assumptions about appropriate interest and depreciation rates. Using the same 10% rate for each housing system shows capital costs per dozen for the aviary and the enriched housing system are much higher than capital costs per dozen for the conventional house. The aviary has average operating costs (feed, labor, pullet, energy, and miscellaneous costs that recur for each flock and vary with egg production) about 23% higher and average total costs about 36% higher compared with the conventional house. The enriched housing system has average operating costs only about 4% higher compared with the conventional house, but average total costs are 13% higher than for the conventional house. © The Author 2015.

    Recently the smart grid has been a hot issue in the research area. The Electric Vehicle (EV) is the most important component in the Smart Grid, having a role of the battery component with high capacity. We have thought how to introduce the EV in the housing development, and for proper operation of the smart grid systems in the housing area the authentication system is essential for the individual houses. We propose an authentication system to discriminate an individual houses, so that the account management component can appropriately operate the electrical charging and billing in the housing estate. The proposed system has an architecture to integrate the charging system outside a house and the monitoring system inside a house.

    Alternative hen housing is becoming more commonplace in the egg market. However, a complete understanding of the implications for alternative housing systems on egg safety has not been achieved. The current study examines the impact of housing Hy-Line Brown, Hy-Line Silver Brown, and Barred Plymouth Rock hens in conventional cage, cage-free, and free range egg production systems on shell microbiology. Eggs were collected at 4 sampling periods. Egg shell emulsion pools were formed and enumerated for total aerobic organisms, Enterobacteriaceae, and yeast and mold counts. Hy-Line Brown and Hy-Line Silver Brown hens produced eggs with significantly (P Eggs from conventional cages had significantly different (P eggs with significantly different (P eggs having the lowest level of contamination for the hen strains. There were no differences within each strain among housing systems for yeast and mold contamination. The study shows that hen strain has an effect on egg microbial levels for various housing systems, and egg safety should be considered when making hen strain selections for each housing system.

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

    Very few studies concern the effects of layer housing systems and age on egg technological properties. Thus the aim of this work was to study the influence of these two factors on egg performance in fresh pasta production, focusing on pasta cooking behaviour. Samples of pasta subjected to analysis were prepared with eggs laid by Hy-Line Brown hens (from 27 to 68 weeks old) housed in cage, barn and organic systems. Higher average values of weight increase and matter loss during pasta cooking were observed for samples prepared with eggs laid by older hens. Such cooking behaviour indicated the development of a weaker pasta protein network, resulting from a decrease in the quantity of albumen protein and an increase in fat content, which is due to the reduction in albumen/yolk ratio during hen aging. The housing system had a significant effect only on matter loss in cooking water, but differences between samples were so small as to be unlikely perceived by consumers. Both hen age and housing system significantly affected pasta cooking behaviour, but the greatest effect was exerted by the hen age. Copyright © 2010 Society of Chemical Industry.

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.

    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

    Energy management is a system of managing energy utilization wisely and it includes issues such as energy efficiency (conservation), use of renewable energy, use of technology and development of energy policy. Its benefits has been well known for cost reduction and increase competitiveness and also other indirect impact such as preserving the natural resources and reduction of green-house gases. Although various strategies have been formulated by the government for the industries to adopt energy management, the result seems to be minimal and stagnant in some ways due to the various barriers which exists. Industries on the other hand, have successfully welcomed two famous management system namely the Environmental Management System ISO 14000 and the Quality Management System ISO 9000 to be implemented at their premises. This paper shows how energy management system can be effectively implemented by comparing similar generic management elements of energy management to ISO 9000/14000 standards. The seven (7) elements of energy management system discussed are top management commitment, policy establishment, energy management team, energy audit, energy efficiency projects, monitoring and training

    During the past few years, remarkable affords have been made for the realization of microscale sensors, actuators and microelectromechanical system. Due to advances in solid state and micromachining technologies, significant advances in designing, fabricating and testing of microminiaturized devices have been achieved at laboratory level. However, the technical and economical realization of microelectromechanical systems is considerably impeded by the lack of satisfying device technology for their industrial production. A production concept for the industrial production of hybrid microelectromechanical systems was developed and investigated. The concept is based on the resources and requirements of medium-sized enterprises and is characterized by its flexibility. Microsystem fabrication is separated into microfabrication steps performed in-house and technological steps performed by external technology providers. The modularity of the concept allows for a gradual increase in the degree of automation and the in-house production depth, depending on market capacity and financial resources. To demonstrate the feasibility of this approach, the design and realization of a microfabrication process center, which includes tasks like transport and handling, processing, cleaning, testing and storing are discussed. Special attention is given to the supply and feeding of microparts, to the necessary magazines, trays and transport systems, to the implementation of homogeneous mechanical, environmental and information interfaces, to the employment of advanced control, scheduling, and lot tracking concepts, and to the application of highly modular and cost-efficient clean production concepts.

    Full Text Available In a highly competitive global economy the development of sustainable, innovative responses from Industry is now vital. Many industries globally need to respond rather than react to current economic climate through sustainable (economically and environmentally development. The steel industry is a critical player in the urban landscape. Like many industries, small, medium enterprises (SMEs are vital players within the steel industry supply chain. The Australian SME steel housing sector (based in rural and regional areas are still developing systemic capabilities with the aim of realizing its full potential. The question of an effective sustainable industry is much larger than any one player. This paper aims to present a proposed methodological approach for sustainable cluster development based on previous industry wide investigations. Through the lens of scalability of a socio complex adaptive system, SME development becomes arguably the most significant player with regards to industry cluster development. By starting with SME development it's possible to build an understanding of a simultaneous two layered approach, "bottom up – top down" whilst including a very diversified group.

    2017-11-01

    Construction industry has moved forward into a technology driven where a transition is in progress from conventional method to a more advanced and mechanised system known as the Industrialised Building System (IBS). However, the need to implement the IBS should be well understood by all construction players such as designer, architect, contraction, erectors and construction workers. Therefore, there is a need to educate all these construction players which should be spearheaded by authorities such as Construction Industrial Development Board where enforcement trough building by laws as well as initiative to those that adopt the IBS in their construction. This paper reports on economic aspects of using interlocking hollow brick system in construction as an alternative method offered for Industrialized Building System. The main objective is to address the economic aspects of using interlocking block system in terms of time, costs, and utilization of manpower and to present some of the experimental tests results related to Interlocking Hollow Brick System (IHBS). Example of savings from the use of IHBS is presented in this paper by comparing the construction of two storey terrace house with build-up area of about 200 square meter with conventional construction method of typical reinforced concrete construction (RCC) compared to IHBS. The comparison shows that the implementation of IHBS can reduce construction time, cost, and utilization of man power up to 26.6% compared to the conventional method. Moreover, the construction time using IHBS can also be reduced by up to 50% as compared to the conventional construction.

    2010-01-01

    The housing growth programme could offer an opportunity for accelerating the deployment of decentralised renewable energy systems (DRES) in the UK. The Government hopes to leverage private sector investment into DRES as part of new housing projects. The aim of this paper is to assess whether current regulatory and funding frameworks are sufficient to achieve this. The question is explored by drawing on the experience of developers, local authorities, energy utilities and service companies operating in the largest housing growth region in the UK-Thames Gateway. Their experience suggests that the current low intervention approach will be insufficient to generate the shift required in both industries. In order to be more successful economic and regulatory instruments should focus on producers (house-builders and energy providers) rather than consumers (households). Tighter regulation is needed to ensure that producers have a responsibility to install DRES as part of new developments, to enable connection to the grid, to ensure a sustained financial return from investment and revenue is spent on the expansion of new renewable energy infrastructure. This regulatory framework must be under-pinned by substantial funds focused on producers. Greater intervention is needed if DRES is to be included in new housing development.

    Whole-house ventilation systems are becoming commonplace in new construction, remodeling/renovation, and weatherization projects, driven by combinations of specific requirements for indoor air quality (IAQ), health and compliance with standards, such as ASHRAE 62.2. Ventilation systems incur an energy penalty on the home via fan power used to drive the airflow, and the additional space-conditioning load associated with heating or cooling the ventilation air. Finding a balance between IAQ and energy use is important if homes are to be adequately ventilated while not increasing the energy burden. This study used computer simulations to examine RIVEC the Residential Integrated Ventilation Controller - a prototype ventilation controller that aims to deliver whole-house ventilation rates that comply with ventilation standards, for the minimum use of energy. Four different whole-house ventilation systems were simulated, both with and without RIVEC, so that the energy and IAQ results could be compared. Simulations were conducted for 13 US climate zones, three house designs, and three envelope leakage values. The results showed that the RIVEC controller could typically return ventilation energy savings greater than 40percent without compromising long-term chronic or short-term acute exposures to relevant indoor contaminants. Critical and average peak power loads were also reduced as a consequence of using RIVEC.

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

    This article presents findings from a community-based participatory evaluation of a Housing First program on the Island of O’ahu. In this study, clients in a Housing First program used Photovoice to evaluate the program and to advocate for progressive housing policies. Written together by members of the Housing First Photovoice group, this collaborative article describes the outcomes from both the Housing First program and the Photovoice project and demonstrates the ways in which participatory program evaluations can interact with client-driven programs like Housing First to produce a cumulative, transformative impact. Findings suggest that community psychologists hoping to re-engage with community mental health systems through enacting transformative change should consider taking a community-based participatory approach to program evaluation because increased client voice in community mental health programs and their evaluations can have far-reaching, transformative impacts for research, practice, and policy.

  6. Thermal Storage Systems Assessment for Energy Sustainability in Housing Units

    Directory of Open Access Journals (Sweden)

    Tania I. Lagunes Vega

    2016-04-01

    Full Text Available In order to achieve greater enhancements in energy sustainability for housing, the function and efficiency of two different passive cooling systems were studied: encapsulated water in recycled bottles of Polyethylene terephthalate (PET and polystyrene plates, in comparison with standard concrete slab systems, which are customarily used in housing. Experiments were placed over a tile surface, in which temperature changes were monitored for a period of 20 days from 08:00 to 20:00. The efficiency of passive thermal storage systems was endorsed through statistical analysis using the “SPSS” software. This resulted in a 17% energy saving, thus promoting energy sustainability in housing units, which reduces the use of electrical appliances required to stabilize conditions to achieve optimum thermal comfort for the human body inside a house, therefore, reducing electrical power consumption, CO2 emissions to the atmosphere and generating savings. Due to the complexity of a system with temperature changes, a fractal analysis was performed for each experimental system, using the “Benoit” software (V.1.3 with self-compatible tools of rescaled range (R/S and a wavelets method, showing that the thermal fluctuations on the tiles with the thermal storage system adapt to the rescaled range analysis and the regular tiles adapt to the wavelets method.

    Highlights: • We simulate a cooling tower coupled with heat pump system and a single zone using TRNSYS. • We examine the temperature of water inside the cooling tower and inside the single zone. • We study the temporal evolution of the all parameters for 4500 h operation in winter in Tunisia. - Abstract: The industrial cooling towers in Tunisia meet difficulties due to the poor coordination between the utility and process sectors. In this study, we will consider especially the vapor recovery of the wastewater from the industrial activity in south Tunisia. By using the heat pump for high capacity, the problem for vapor from wastewater may be resolved. The coupling for the cooling tower and the heat pump system is investigated by TRNSYS software. The system of cooling tower is also associated with a single zone which is related to heat exchangers. An optimization model for the operation of a cooling water system was developed that accounts for a cooling tower, and a network of pipelines and heat exchangers for heating a single house. This work is based on numerical studies; the cooling tower performance, the single house, the heat pump and the heat exchanger that are simulated using TRNSYS model. The circulation of cooling water system is assured by a counter flow. The evaluations of the cooling tower geometry and performances are based on an adaptive version of Merkel’s method witch integrated in TRNSYS. The results of optimization using TRNSYS are validated by several theoretical and experimental studies

    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

    Full Text Available The aim of this study was to evaluate PM10 concentration in three different laying hens houses (traditional battery cages with aerated open manure storage, aviary system and vertical tiered cages with manure belts with forced air drying and to evaluate particulate matter emission into atmosphere during one year of observation. Internal and external temperature and relative humidity, ventilation rate, PM10 concentration have been continuously monitored in order to evaluate particulate matter concentration changes during the day and the season and to define PM10 emission factors. PM10 concentration was corrected by gravimetric technique to lower measurements error. In the aviary system house, TSP and fine particulate matter (particles smaller than 2.5 micron concentration was measured. Average yearly PM10 concentration was remarkably higher in the aviary system house with 0.215 mg m-3 vs 108 mg m-3 for the ventilated belt house and vs 0.094 mg m-3 for the traditional battery cages house. In the Aviary system housing, TSP concentration was 0.444 mg m-3 and PM2.5 was 0.032 mg m-3, highlighting the existence of a severe working environment for men and animals. Recorded values for PM10 emission were 0.433 mg h-1 hen-1 for battery cages housing type, 0.081 mg h-1 hen-1 for ventilated belt cages house, values lower than those available in literature, while the aviary system housing type showed the highest PM10 emission (1.230 mg h-1 hen-1 with appreciable peaks during the morning, together with the increased animal activity and daily farmer operations, as feed administration, cleaning and droppings removal.

    Radon levels were monitored in three similar two-story apartment houses which were located side by side on a gravel esker in eastern Finland. The houses differed only in regard to their ventilation systems which included the following: natural ventilation, mechanical exhaust, and complete mechanical ventilation. The study started immediately when the houses were finished and was continued for two years. Radon concentrations were highest (60-430 Bq/m 3 ) in the beginning of the study period before the tenants moved in. During the following spring and fall, average radon levels of the houses decreased below 100 Bq/m 3 . Radon concentrations varied within a wide range, from 20 to 230 Bq/m 3 , in the apartments. Among the houses, the highest concentrations were found in the house equipped with mechanical exhaust ventilation and the lowest in the house with both a mechanical supply and exhaust system. One reason for the decreasing levels of radon after a one-year occupancy was that the tenants increased the ventilation of their apartments. In the house with complete mechanical ventilation, the stability of ventilation also contributed to the decrease of the indoor radon level

    In the United States, there is an increase in need for cage-free eggs in retail and food manufacturing sectors. Understanding the impact of cage-free systems and the corresponding management on egg quality is pertinent as the U.S. industry adapts existing housing and builds new cage-free housing structures. A study was conducted comparing 2 brown shell and 2 white shell hen strains housed in a cage-free aviary system. Each set of eggs were placed in cold storage and assessed at 0, 2, 4, 8, and 12 wk. Eggs were collected at 21, 31, 42, and 60 wk of hen age. A full profile of physical quality measurements was conducted on up to 18 intact eggs for each hen strain/egg storage/hen age combination. Egg weight increased approximately 10 g for brown shell and 14 g for white shell eggs as hens aged. Many of the properties monitored were significantly impacted by all 3 main effects (hen strain, egg storage, and hen age) resulting in 3-way interactions. A brown and a white shell strain had stronger shells (44 N; P study also determined volume of shell, total length, maximum width, and percent length at maximum width to more accurately indicate egg shape than shape index. One brown shell strain produced eggs with the most consistent shape characteristics over the hen ages monitored. White shell eggs from the cage-free aviary housing produced the highest whole-egg total solids between 31 to 60 wk of hen age, whereas brown shell eggs resulted in the most consistent level of whole-egg total solids (22-23.5%). The brown and white shell strains in the current study produce cage-free aviary eggs with distinctive physical quality attributes. The outcomes from this study can be utilized by the U.S. egg industry in planning management strategies and market placement of cage-free eggs.

Today there is a number of problems, which doesn't allow housing and utility services to function effectively. The main of them is providing high-quality housing and utility services to the population and system of their objective cost assessment. This problem is solved by means of reforming the housing and utility sphere with the possibility of attracting financial resources from private investors. Housing and Utility of the Russian Federation, the basis of which is the housing stock, has a very high specific weight in fixed assets of all the economy.Thus, Housing and Utility is a typical difficult organizational and economic system possessing characteristic features of openness, nonlinearity and dissipativity. In this re-gard, the reasonable approach to Housing and Utility development assumes the need to account for the principles of systemacity, focus and complexity, and also can be based on the existing in the theory and practice of management methodology by difficult organizational and economic systems.Now Housing and Utility development and financing investment programs of the municipal complex organizations is carried out according to the relevant Federal law, according to which the establishment system of limit indexes of change of tariffs and investment extra charges to tariffs for services of the organizations of a municipal complex. Also, innovative ways of energy efficiency increase and decrease in wear of funds is an attempt of the state to develop effective mechanisms of attracting private funds from investors.

  1. RETHINKING HOUSING EDUCATION IN ARCHITECTURE SCHOOLS

    Full Text Available Architects are involved in only a small percentage of all built projects and are becoming marginalized in the huge home-building industry where other professions are moving in to profit from the need for affordable housing. The vast majority of homebuyers today view housing as a commodity and are unwilling to spend more on an architect-designed house. Architects must expand the market for their services to include a far greater percentage of new buildings. It is my contention that the new place for architects is in the design of speculative housing as expert consultant to the developer. The practice of architecture must change emphasis to consider more social and economic concerns. The attitudes and skills currently being taught in architecture schools must change to reflect the new needs of the profession. Architects must be taught behavioral psychology, demographics, and building economics to enable them to apply their knowledge to the market, thereby rendering the architect’s services indispensable to developers and the housing industry. Architectural education must play a key role in redefining the scope of the profession.

The objective is to demonstratehow a new paradigm for the conceptualization and construction of buildings can be conceivedof as an entirely factory based process that creates advantages for construction through industrialsystems technology transfer. Our approach is intended to transform design methodologythrough demonstrating how alternative construction concepts, using entirely pre-manufacturedvolumetric units, can be adopted. This involves digital modeling that facilitates parametric variationsfor creating customized prefabricated products from design conceptualization through tofinal product delivery. The paper discusses key areas under investigation in relation to a manufacturingparadigm used in the automotive industry that integrates virtual prototyping and industrialmanufacturing systems. Our research explores a type of monocoque volumetric unit prefabricatedin steel, which will be pre-finished as part of a modular factory-built approach usingindustrialized methodologies that will facilitate customized manufacture of a high quality energyefficient product for affordable housing.The paper addresses the automotive industry methods of manufacture that have served increasedautomobile performance and economics through mass production for over a century. In starkcontrast, the building industry and in particular the housing industry is still a century behind. It issuggested that a move away from tradition will require an industry wide initiative, just like HenryFord led the way with mass production. By embracing the increasing sophistication and capabilitythat digital technology offers, it is shown how digital tools are implemented towards masscustomization in house design using virtual modeling in the

    Full Text Available Housing is a fundamental product for every human being irrespective of financial standing. World acclaimed American psychologist, Abraham Maslow ranked shelter as second only to food in his hierarchy of human needs. Despite the importance of housing to the socio-economic development of man and the nation, housing problems have remained endemic throughout the world. In today’s world, some 100 million persons are homeless and more than a billion are inadequately housed. In 2002 housing deficit in Nigeria was put at about 8 million units. Latest statistics indicate that Nigeria requires a whopping 700,000 housing units annually for the next 15 years. The question is why this state of affairs? Why the perennial and unending problems of housing shortages, forced evictions and slum development? The paper examined these issues in Nigeria in order to advance the future prospect of the sector. The paper identified that whilst reforms were been made to all other subsector of the housing industry, land reform necessary to fast track the process was left unattended to by the government. The paper thus advocated for a robust reform of the current land management system in order to impact positively on the housing reform agenda in Nigeria.

    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.

  7. Beyond Housing First: Essential Elements of a System-Planning Approach to Ending Homelessness

    Directory of Open Access Journals (Sweden)

    Alina Turner

    2014-10-01

    Full Text Available The concept of “Housing First” has taken on a powerful status in the complex of government, non-profit and academic systems that study and seek to eliminate homelessness. It is a compelling concept, in that it has brought our society to the realization that housing instability itself is often the culmination of various underlying and intersecting issues, ranging from mental health and addiction issues to domestic abuse and poverty. The “Housing First” principle holds that homeless individuals stand a far poorer chance of improving their condition while they remain homeless; that the stability of a permanent home provides the foundation that allows individuals to begin addressing the issues that led to their housing instability in the first place. However, the elegance of the fundamental principle behind “Housing First” also risks creating an illusion, wherein agencies and governments might too easily conclude that the entirety of this approach to ending homelessness is merely to begin housing the homeless. While that is a step in the process, it is but a piece of the Housing First approach. And unless all the various elements of the approach are also included in the actual work done on the ground, the success observed so far in communities that have tried the Housing First approach will not necessarily be replicated. This can lead to disappointment for those trying to implement new strategies, undermine the effectiveness of Housing First, and most importantly, fail to fully help those individuals in need. Housing First encompasses a strategic application of key principles across the entire homeless-serving system. When it is introduced into a new jurisdiction, it must be accompanied by an overhaul of the current approach to social policy and service delivery. The implementation of Housing First requires a difficult and systematic process, beginning with planning and strategy development that recognizes how every part of the homeless

  11. The Provision of Visitable Housing in Australia: Down to the Detail

    Directory of Open Access Journals (Sweden)

    2015-04-01

    Full Text Available In response to the ratification of the United Nations Convention of the Rights of People with Disabilities (CRPD, Australian housing industry leaders, supported by the Australian Government, committed to transform their practices voluntarily through the adoption of a national guideline, called Livable Housing Design. They set a target in 2010 that all new housing would be visitable by 2020. Research in this area suggests that the anticipated voluntary transformation is unrealistic and that mandatory regulation will be necessary for any lasting transformation to occur. It also suggests that the assumptions underpinning the Livable Housing Design agreement are unfounded. This paper reports on a study that problematised these assumptions. The study used eleven newly-constructed dwellings in three housing contexts in Brisbane, Australia. It sought to understand the logics-of-practice in providing, and not providing, visitable housing. By examining the specific details that make a dwelling visitable, and interpreting the accounts of builders, designers and developers, the study identified three logics-of-practice which challenged the assumptions underpinning the Livable Housing Design agreement: focus on the point of sale; an aversion to change and deference to external regulators on matters of social inclusion. These were evident in all housing contexts indicating a dominant industry culture regardless of housing context or policy intention. The paper suggests that financial incentives for both the builder and the buyer, demonstration by industry leaders and, ultimately, national regulation is a possible pathway for the Livable Housing Design agreement to reach the 2020 goal. The paper concludes that the Australian Government has three options: to ignore its obligations under the CRPD; to revisit the Livable Housing Design agreement in the hope that it works; or to regulate the housing industry through the National Construction Code to ensure the

    Understanding concerns about the welfare of farm animals is important for the development of socially sustainable production practices. This study used an online survey to test how views on group versus stall housing for pregnant sows varied when Canadian and US participants were provided information about these systems, including access to scientific papers, YouTube videos, Google images, and a frequently-asked-questions page (S1 Appendix). Initial responses and changes in responses after accessing the information were analyzed from Likert scores of 242 participants and from their written comments. Participants were less willing to accept the use of gestation stalls after viewing information on sow housing. For example, initially 30.4% of respondents indicated that they supported the use of gestation stalls; this declined to 17.8% after participants were provided additional information. Qualitative analysis of comments showed that supporters of gestation stalls expressed concern about the spread of disease and aggression between animals in less confined systems, whereas supporters of group housing placed more emphasis on the sow's ability to interact socially and perform natural behaviors. These results point to public opposition to the use of gestation stalls, and indicate that the more that the public learns about gestation stalls the less willing they will be to accept their use.

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

    Urbanization in Ho Chi Minh City (HCMC), Vietnam is rapidly increasing. Therefore, social housing for workers who work at industrial park and processing areas, is indispensable. There are difficulties and conflicts which still remain in developing the social housing for those people in HCMC. For example, the demand of social housing is high, however employers and/or business owners did not fully pay their attentions on social houses to support the workers. On another hand, even if they built the houses, these one seem not to be sufficient for the demands and/or unable to be competed to the rental housing market from private landlords. Building a social housing model for those workers is a vital importance, this aims to improve the quality of life for the workers; for examples, healthcare, personal safety, social relationships, emotional well-being, quality of living environment, etc. In this research, we study the investment, management, and operation of the social housing for workers in HCMC. This also seeks a new housing model which will adapt the criteria towards the sustainable economic development of HCMC.

    To determine the advantages and disadvantages of a shift system of working compared with the conventional on call system for preregistration house officers. A shift system of working was employed in the unit from 1 August 1989 to 31 July 1990. During attachments of three or six months four house officers rotated at intervals of one month among three daytime shifts and one night shift (Mondays to Fridays only). Weekends (48 hours) were worked on a one in three rota by the doctors working a day shift. The views of the house officers working this shift system were sought in writing and by direct interview. Professorial surgical unit, Royal Liverpool Hospital. The 14 house officers who were attached to the unit for three or six months during their preregistration year. The shift system was preferred to conventional on call without exception. The incidence of chronic tiredness was reduced and formal hand-over between shifts resulted in more informed decision making by doctors while on call. During annual leave it was sometimes necessary to revert to the conventional one in three on call system to ensure that daytime work was completed. Other disadvantages were the long weekend shift and an inequitable distribution of the night shift. The house officers recommended extending the shifts to weekends and working the night shift one week in four. A shift system of working was effective in reducing chronic tiredness among house officers, who found it preferable to conventional on call arrangements. Shift working is feasible only if the daytime duties of the doctor working at night can be completed by the other doctors on the rota.

    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.

Given the particular nature of the subsoil that occurs in these regions affected, subsidence can generate cracks and fractures that are evident on the surface of the soil causing differential settlement affecting all types of construction causing considerable damage to the structural elements of the dwellings. The materials traditionally used for housing construction such as masonry and concrete among others, have stiffness characteristics that make them especially vulnerable to these effects. In contrast, steel is an excellent choice for use due to their structural characteristics, such as its high tensile strength, ductility, compressive good performance, high efficiency in weight — strength ratio, among other qualities. The cold formed thin-walled steel elements, are another type of very light profiles, although its use has been known for several decades, is in recent times that have extended their application, mainly in housing construction, and to a lesser scale commercial and industrial construction. The main advantage of this material is that it retains the mechanical properties of steel, but with a significant reduction in the weight of the items. The most common use of this type of profile is in the manufacture of structural frames as standard modules, the most common form it is assembly profile channel with rigid edge section and section profiles of single channel, with different dimensions and sizes. In full-scale testing and numerical simulation models, the system exhibits an excellent performance under differential displacements as those caused by subsidence, accepting considerable deformations without reaching the failure of structural elements.

  6. A planning support system to optimize approval of private housing development projects

    Science.gov (United States)

    Hussnain, M. Q.; Wakil, K.; Waheed, A.; Tahir, A.

    2016-06-01

    Out of 182 million population of Pakistan, 38% reside in urban areas having an average growth rate of 1.6%, raising the urban housing demand significantly. Poor state response to fulfil the housing needs has resulted in a mushroom growth of private housing schemes (PHS) over the years. Consequently, only in five major cities of Punjab, there are 383 legal and 150 illegal private housing development projects against 120 public sector housing schemes. A major factor behind the cancerous growth of unapproved PHS is the prolonged and delayed approval process in concerned approval authorities requiring 13 months on average. Currently, manual and paper-based approaches are used for vetting and for granting the permission which is highly subjective and non-transparent. This study aims to design a flexible planning support system (PSS) to optimize the vetting process of PHS projects under any development authority in Pakistan by reducing time and cost required for site and documents investigations. Relying on the review of regulatory documents and interviews with professional planners and land developers, this study describes the structure of a PSS developed using open- source geo-spatial tools such as OpenGeo Suite, PHP, and PostgreSQL. It highlights the development of a Knowledge Module (based on regulatory documents) containing equations related to scheme type, size (area), location, access road, components of layout plan, planning standards and other related approval checks. Furthermore, it presents the architecture of the database module and system data requirements categorized as base datasets (built-in part of PSS) and input datasets (related to the housing project under approval). It is practically demonstrated that developing a customized PSS to optimize PHS approval process in Pakistan is achievable with geospatial technology. With the provision of such a system, the approval process for private housing schemes not only becomes quicker and user-friendly but also

  8. A field study using an adaptive in-house pricing model for commercial and industrial customers in Korea

    International Nuclear Information System (INIS)

    2017-01-01

    Demand response programs provide customers with economic incentives for load reductions at times of high market prices and system reliability constraints. One type of demand response programs, price-based program, induces customers to respond to changes in product rates. However, some large-scale customers find it difficult to change their electricity consumption patterns, even with rate changes, because their electricity demands are commercial and industrial. This study proposes an adaptive in-house pricing model for large-scale customers, particularly those with multiple business facilities, for self-regulating price-based program. The adaptive in-house pricing model charges higher rates to customers with lower load factors by employing a peak-to-off-peak usage ratio in order to reduce usage at times of high prices at each facility. This study analyzes the daily electricity consumption patterns of large-scale customers through a field trial of the proposed pricing model at a telecom company with 447 offices and worksites for one month. The results show that the pricing model corresponds to average reductions of 3.54–28.69% during peak-demand times for four different types of workplaces. However, reductions in electricity consumption during off-peak periods did not show a significant difference. The results of this study prove that this proposed pricing model can be successfully applied to large-scale operations. - Highlights: • The pricing model induces reductions in energy consumption during peak-demand times. • The greatest decrease occurs in commercial buildings with higher POR. • Data centers with flat loads for necessities can do little to reduce usage.

    In order to comply with the European Union's ambient air quality standards, the Netherlands must reduce emissions of PM10. As a contributor to PM10, the poultry industry must implement mitigation measures before 2012. An extensive research and development program was launched in 2008 to provide abatement technology for broiler and layer houses. This paper presented results from studies carried out in 2008 and 2009 by Wageningen UR Livestock Research. The supply industry and poultry farmers participated in the study in which different methods and approaches were examined, including bedding material, light schedules, oil spraying systems, ionization systems, water scrubbers, combined scrubbers, electrostatic filters, and dry filters. Most methods were first tested and optimized in small units at an experimental poultry facility Lelystad. Several methods were validated in a next step on poultry farms, where PM10 emissions were measured to establish official emission factors. The oil spraying system and ionization system were tested in broiler houses and are nearing implementation. Reductions in PM10 emissions by different methods ranged from no effect to levels of 60 per cent. An outlook on adequate dust abatement measures for poultry housings was also provided.

    2009-01-01

    Full Text Available Abstract Background The husbandry systems for laying hens were changed in Sweden during the years 2001 – 2004, and an increase in the number of submissions for necropsy from laying hen farms was noted. Hence, this study was initiated to compare causes of mortality in different housing systems for commercial laying hens during this change. Methods Based on results from routine necropsies of 914 laying hens performed at the National Veterinary Institute (SVA in Uppsala, Sweden between 2001 and 2004, a retrospective study on the occurrence of diseases and cannibalism, i.e., pecking leading to mortality, in different housing systems was carried out. Using the number of disease outbreaks in caged flocks as the baseline, the expected number of flocks with a certain category of disease in the other housing systems was estimated having regard to the total number of birds in the population. Whether the actual number of flocks significantly exceeded the expected number was determined using a Poisson distribution for the variance of the baseline number, a continuity correction and the exact value for the Poisson distribution function in Excel 2000. Results Common causes of mortality in necropsied laying hens included colibacillosis, erysipelas, coccidiosis, red mite infestation, lymphoid leukosis and cannibalism. Less common diagnoses were Newcastle Disease, pasteurellosis and botulism. Considering the size of the populations in the different housing systems, a larger proportion of laying hens than expected was submitted for necropsy from litter-based systems and free range production compared to hens in cages (P P P Conclusion The results of the present study indicated that during 2001–2004 laying hens housed in litter-based housing systems, with or without access to outdoor areas, were at higher risk of infectious diseases and cannibalistic behaviour compared to laying hens in cages. Future research should focus on finding suitable prophylactic

    Full Text Available Central to this PhD research was the problem of the lack of affordable housing for young starters in Malaysia. The solutions for affordable housing that are available in the market do not truly solve the problem from the customer’s point of view. Hence, it was important to analyse the contributing factors associated with the term ‘affordability’. The term touches upon interconnected elements that cover many issues ranging from demand (housing needs, demographics, household income, quality housing to supply (the authorities’ requirements, design, cost, sustainability and procurement. In this thesis, we discuss some of the problems related to the supply and demand issues and examine a possible intervention to solve the problem. This research contributed to the body of knowledge by employing a prescriptive strategy and designing an innovative flexZhouse business model (BM, and by applying an in-depth strategy that revealed why the problem exists and why there is still no appropriate solution. The result provides a description of the situation that young starters find themselves in, the reactions of the industry’s key players and the policies that hamper innovation in the housing market. Methodology We applied the model of ‘design sciences’ as described by Van Aken (2004. The strategy first helped us to understand the problem (the issues related to the term ‘affordable housing’; the next step was to prescribe solutions for the practice by formulating the draft flexZhouse business model (BM. The mission of this research was to further develop knowledge for the design and understanding the problems that is, to provide alternative solutions to the affordable housing demands in the housing industry in Malaysia. We used the term ‘design research’ from Van Aken (2004 because the ultimate objective of studies in this category is to acquire a knowledge of how to develop solutions to problems in the real world (i.e. the new business

    This work gives an overview of research and development carried out at IIT Madras, using glass fibre reinforced gypsum (GFRG) panels, to provide an innovative solution for rapid and affordable mass housing. The GFRG panels (124 mm thick), made from recycled industrial waste gypsum (from the fertilizer industry), are prefabricated in 3 m × 12 m sizes with cellular cavities inside, which can be filled with reinforced concrete wherever required and can be used as walls as well as floor slabs. The tests carried out (over the past 12 years) establish the performance of GFRG building systems to resist gravity and lateral loads as a load-bearing system (without beams and columns) in multi-storeyed buildings up to 8-10 storeys, with adequate strength, serviceability, durability and ductility. A two-storeyed four-apartment demonstration building has also been successfully constructed in the IIT Madras campus and presently a mass housing scheme (40 apartment units) using this technology is being demonstrated at Nellore. A structural design code has also been approved by the Bureau of Indian Standards, based on the extensive studies carried out on GFRG building systems.

    Elswijk, M.; Kaan, H. (eds.) [and others

    2008-05-15

    The passive house concept has become a European wide accepted solution to reach a significant energy demand reduction in the built environment. The European Commission has published the ambition to construct newly built ho uses in 2015 accordingly to the passive ho use standard. In most project participating countries this ambition is shared. With the support of the Intelligent Energy Europe program this project 'Promotion of European Passive Houses' (PEP-project) contributed to achieve this ambition to clear the first market barriers internationally to reach the status 'Business As Usual' for passive houses in 2015. The PEP project aimed at the development of easy accessible web based documentation for stakeholders in the building process to solve national market introduction barriers regarding the passive house concept. The project also aimed at the distribution of this information via international and national workshops, seminars and conferences. It can be concluded that the PEP-project has been successful. All participating countries made significant progress in the societal embedding process of passive houses and in most countries the passive house concept is on the brink of breaking through nationally. Further, the PEP-project contributed successfully in the internationalisation of the Internal Passive House Conference and fixed the definition of a passive house for three geographical European regions. Finally, the PEP website with its wealth of information was a powerful tool for promotion of passive houses in Europe. In order to increase the implementation efficiency of the passive house concept it is recommended to develop additional information packages concerning passive house solutions for offices, schools and social homes (e.g. architectural examples, organisational issues); passive house renovations; financial schemes for passive houses; performance oriented quality approach for the design and construction process; industrial

Tech House equipment performed well in initial tests, but a house is not a home until it has people. That's where the Swains come in. NASA wants to see how the various systems work under actual living conditions, to confirm the effectiveness of the innovations or to determine necessary modifications for improvement. The Swains are occupying the house for a year, during which NASA engineers are computer monitoring the equipment and assembling a record of day-to-day performance. . Tech House is a laboratory rather than a mass production prototype, but its many benefits may influence home design and construction. In a period of sharply rising utility costs, widespread adoption of Tech House features could provide large-scale savings to homeowners and potentially enormous national benefit in resources conservation. Most innovations are aerospace spinoffs: Some of the equipment is now commercially available; other systems are expected to be in production within a few years. Around 1980, a Tech House-type of home could be built for $45-50,000 (1 976 dollars). It is estimated that the homeowner would save well over $20,000 (again 1976 dollars) in utility costs over the average mortgage span of 20 years.

    2018-06-15

    The objective of this study is trying to solve water pollution problems related to duck house wastewater by developing a novel duck house wastewater treatment technology. A pilot-scale sequencing batch reactor (SBR) system using different hydraulic retention times (HRTs) for treating duck house wastewater was developed and applied in this study. Experimental results showed that removal efficiency of chemical oxygen demand in untreated duck house wastewater was 98.4, 98.4, 87.8, and 72.5% for the different HRTs of 5, 3, 1, and 0.5 d, respectively. In addition, removal efficiency of biochemical oxygen demand in untreated duck house wastewater was 99.6, 99.3, 90.4, and 58.0%, respectively. The pilot-scale SBR system was effective and deemed capable to be applied to treat duck house wastewater. It is feasible to apply an automatic SBR system on site based on the previous case study of the farm-scale automatic SBR systems for piggery wastewater treatment.

    2007-04-01

    Norway is a member of Annex 32, 'Economical heating and cooling systems for low-energy houses' (2006-2008), organized under the umbrella of the International Energy Agency (IEA) and the IEA Heat Pump Programme (HPP). The 9 participating countries are Switzerland (Operating Agent), Austria, Canada, Germany, Japan, the Netherlands, Norway, Sweden and the USA. The Norwegian participation is financed by Enova SF, and SINTEF Energy Research is responsible for planning and carrying out the Norwegian activities. Task 1 of the project is a state-of the art analysis of the low-energy building market and heat pump technologies applied in this type of buildings. Heating demands for low-energy houses and passive houses in Norwegian climate are characterized as follows: The ratio of the annual heating demand for hot water heating and the total annual heating demand of the houses typically range from 40 to 85 percent, and the heating season for space heating and heating of ventilation air range from about 5-7 and 4-6 months per year for semi-detached houses and flats, respectively (Oslo climate). In comparison, the heating season for semi-detached houses and flats constructed in accordance with the Norwegian building codes of 1997 is 8 and 9 months, respectively. Development companies for residential properties, co-operative building societies as well as housing manufactures are now showing great interest in low-energy houses and passive houses. According to The Norwegian State Housing Bank, almost 10.000 residences with low-energy or passive house standard are now being planned, constructed or have been completed. The projects include single-family houses, semi-detached houses, row houses, block of flats and apartment buildings. The main focus in these projects has been on the architectural design, building construction and efficient ventilation systems, and less on the heating (and cooling) systems. The heat pump market in this market segment is regarded to be promising due to

  1. IDEAhaus: A Modular Approach to Climate Resilient UK Housing

    Directory of Open Access Journals (Sweden)

    Greg Keeffe

    2014-09-01

    Full Text Available This paper describes the result of a project to develop climate adaptation design strategies funded by the UK’s Technology Strategy Board. The aim of the project was to look at the threats and opportunities presented by industrialized and house-building techniques in the light of predicted future increases in flooding and overheating due to anthropogenic climate change. The paper shows that the thermal performance of houses built to the current UK Building Regulations is not adequate to cope with changing weather patterns, and in light of this, develops a detailed design for a new house: one that is industrially produced and climatically resilient, but affordable. This detailed concept IDEAhaus of a modular house is not only flood-proof to a water depth of 750 mm, but also is designed to utilize passive cooling, which dramatically reduces the amount of overheating, both now and in the future.

  3. Model-predicted ammonia emission from two broiler houses with different rearing systems

    Directory of Open Access Journals (Sweden)

    Nilsa Duarte Silva Lima

    2015-10-01

    Full Text Available Ammonia (NH3 emissions from broiler production can affect human and animal health and may cause acidification and eutrophication of the surrounding environment. This study aimed to estimate ammonia emissions from broiler litter in two systems of forced ventilation, the tunnel ventilation (TV and the dark house (DH. The experiment was carried out on eight commercial broiler houses, and the age of the birds (day, d, pH and litter temperature were recorded. Broilers were reared on built-up wood shaving litter using an average flock density of 14 bird m–2. Temperature and relative humidity inside the broiler houses were recorded in the morning during the grow-out period. A factorial experimental design was adopted, with two types of houses, four replicates and two flocks with two replicates each. A deterministic model was used to predict ammonia emissions using the litter pH and temperature, and the day of grow-out. The highest litter temperature and pH were found at 42 d of growth in both housing systems. Mean ambient air temperature and relative humidity did not differ in either system. Mean model predicted ammonia emission was higher in the DH rearing system (5200 mg NH3 m−2h−1 at 42 d than in the TV system (2700 mg NH3m−2 h−1 at 42 d. TV presented the lowest mean litter temperature and pH at 42 d of growth. In the last week of the broilers’ grow-out cycle, estimated ammonia emissions inside DH reached 5700 mg m−2h−1 in one of the flocks. Ammonia emissions were higher inside DH, and they did not differ between flocks. Assuming a broiler market weight in Brazil of close to 2 kg, ammonia emissions were equivalent to 12 g NH3 bird-marketed−1. Model-predicted ammonia emissions provided comprehensible estimations and might be used in abatement strategies for NH3 emission.

    2016-03-01

    On 1 January 2012, conventional cages for laying hens were banned in the European Union (EU); all egg farmers must now use alternative hen housing systems. In total, 218 Flemish egg farmers were surveyed in 2013 to 2014 regarding which housing systems they currently use, their degree of satisfaction with the system, and how they experienced the transition from conventional cages to an alternative system. The response rate was 58.3% (127 respondents). Of these, 43 (33.9%) were no longer active as an egg farmer, mainly due to the ban on conventional cages. The respondents who were active as egg farmers both before and after the transition (84, 66.1%) mainly judged the ban as negative for their own finances and for the competitive position of the Belgian egg industry, but were neutral or positive regarding the general consequences for their own business. Most respondents' hens were housed in either aviary systems (47.7%) or in alternative cage systems (38.2%). When choosing a new system, the fit into the farm and consumer demand were the most important factors. Consumer demand was the main reason for choosing a system with free-range access. In general, egg farmers were satisfied with the system they chose, although this differs between systems. When asked to compare the alternative systems to conventional cages, alternatives were judged to be better for hen welfare and consumer demand, but similar or worse for all other aspects, especially labor. Egg farmers previously using conventional cages judged alternative systems more negatively than those who had no prior experience with conventional cages. Farmers who had experience with free-range systems judged these more positively than those without this experience, e.g., for egg consumer demand, profitability, and hen welfare. These results can possibly be extrapolated to other EU countries in which conventional cages were the most common housing system until 2012, and lessons can be drawn from the farmers' experiences

  8. Comparison of vibration damping of standard and PDCPD housing of the electric power steering system

    Płaczek, M.; Wróbel, A.; Baier, A.

    2017-08-01

    A comparison of two different types of electric power steering system housing is presented. The first considered type of the housing was a standard one that is made of an aluminium alloy. The second one is made of polydicyclopentadiene polymer (PDCPD) and was produced using the RIM technology. Considered elements were analysed in order to verify their properties of vibrations damping. This property is very important taking into account noise generated by elements of a car’s power steering system. During the carried out tests vibrations of analysed power steering housings were measured using Marco Fiber Composite (MFC) piezoelectric transducers. Results obtained for both considered power steering housings in case of the same parameters of vibrations excitations were measured and juxtaposed. Obtained results were analysed in order to verify if the housing made of PDCPD polymer has better properties of vibration damping than the standard one.

  9. The Coalition for Sustainable Egg Supply: A unique public-private partnership for conducting research on the sustainability of animal housing systems using a multistakeholder approach.

    Mench, J A; Swanson, J C; Arnot, C

    2016-03-01

    The growing emphasis on ensuring the sustainability of animal agriculture is providing an impetus for the adoption of new approaches to structuring and conducting research. Sustainability is a complex topic involving many considerations related to the economic, social, and environmental impacts of production systems. Successfully addressing this topic requires multidisciplinary research as well as a high degree of communication with food system stakeholders to ensure that the research results contribute to informed decision making. In this paper, we provide an overview of a public-private partnership, the Coalition for Sustainable Egg Supply (CSES), which was formed to support research evaluating the sustainability of laying hen housing systems. Because of increasing public concerns about the behavioral restriction imposed on laying hens housed in conventional cages, the U.S. egg industry is faced with a need to transition to alternative systems. However, before the CSES project, there was limited information available about how this transition might affect trade-offs related to the sustainability of egg production. The goal of the CSES project was to provide this information by conducting holistic research on a commercial farm that had 3 different hen housing systems. The CSES members represented a variety of stakeholders, including food retailers and distributors, egg producers, universities, and governmental (USDA ARS) and nongovernmental organizations. The CSES was facilitated by a not-for-profit intermediary, the Center for Food Integrity, which was also responsible for communicating the research results to food system stakeholders, including via quantitative and qualitative consumer research. In this paper, we describe the structural aspects of the CSES that were responsible for the successful completion and dissemination of the research as well as the insights that were gained regarding multidisciplinary and multi-institutional collaboration, conducting

    2012-03-01

    We performed the initial assessment of an alternative pressurized intraventilated (PIV) caging system for laboratory mice that uses direct-current microfans to achieve cage pressurization and ventilation. Twenty-nine pairs of female SPF BALB/c mice were used, with 19 experimental pairs kept in PIV cages and 10 control pairs kept in regular filter-top (FT) cages. Both groups were housed in a standard housing room with a conventional atmospheric control system. For both systems, intracage temperatures were in equilibrium with ambient room temperature. PIV cages showed a significant difference in pressure between days 1 and 8. Air speed (and consequently airflow rate) and the number of air changes hourly in the PIV cages showed decreasing trends. In both systems, ammonia concentrations increased with time, with significant differences between groups starting on day 1. Overall, the data revealed that intracage pressurization and ventilation by using microfans is a simple, reliable system, with low cost, maintenance requirements, and incidence of failures. Further experiments are needed to determine the potential influence of this system on the reproductive performance and pulmonary integrity in mice.

    2018-03-01

    Within the last few decades, the North American and European dairy industries have been collecting information about lameness and leg injury prevalence on dairy farms and have tried to develop solutions to mitigate these ailments. Few published articles report the prevalence of lameness and leg lesions in areas outside of those 2 regions, or how alternative housing systems, such as compost-bedded packs, affect the prevalence of these maladies. The objectives of this study were to compare the prevalence of lameness and leg lesions on confined dairies that used freestall, compost-bedded packs, or a combination of these 2 systems in Brazil. Data were collected in the autumn and winter of 2016 from 50 dairy farms located in Paraná state, including 12 compost-bedded pack dairies (CB), 23 freestall dairies (FS), and 15 freestall dairies that used compost-bedded packs for vulnerable cows (FS+C). A visit to the farm consisted of a management questionnaire, an inspection of the housing areas as well as the milking parlor, and an evaluation of all lactating cows as they exited the parlor for lameness (score 1-5), hygiene (score 0-2), body condition score (score 1-5), and hock and knee lesions (score 0-1). Median 1-way chi-squared test was used to compare production systems. We found no difference between farm types in management practices related to hoof health management or average daily milk production per cow [31 (29-33.9) kg/d; median (quartile 1-3)], percentage of Holstein cattle in the herd [100% (90-100%)], conception rate [35.8% (30.2-38%)], or pregnancy rate [15% (13.7-18%)]. The CB farms were smaller [85 (49.5-146.5) milking cows] than both the FS [270 (178-327.5) milking cows] and FS+C farms [360 (150-541.5) milking cows). The overall prevalence of severe lameness (score 4 and 5) across all farms was 21.2% (15.2-28.5%) but was lower on the CB farms [14.2% (8.45-15.5%)] in comparison to the FS [22.2% (16.8-26.7%)] and the FS+C farms [22.2% (17.4-32.8%)].

    In this paper an investigation of floor heating systems is performed with respect to heating demand and room temperature. Presently (2001) no commercially available building simulation programs that can be used to evaluate heating demand and thermal comfort in buildings with building integrated....... The model calculates heating demand, room temperatures, and thermal comfort parameters for a person in the room. The model is based on a numerical Finite Control Volume (FCV) method for the heat transfer in walls, ceiling, windows and floor. The model uses both convective and radiative heat transfer...... to the room air and between the room surfaces. The simulation model has been used to calculate heating demand and room temperature in a typical well insulated Danish single-family house with a heating demand of approximately 6000 kWh per year, for a 130 m² house.

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

    A geothermal heat pump (GHP) is a potential heat source for the economic heating of broiler houses with optimum production performance. An investigation was conducted to evaluate the effect of a heating system using a GHP on production performance and housing environment of broiler chickens. A comparative analysis was also performed between the GHP system and a conventional heating system that used diesel for fuel. In total, 34,000 one-day-old straight run broiler chicks were assigned to 2 broiler houses with 5 replicates in each (3,400 birds/replicate pen) for 35 d. Oxygen(,) CO(2), and NH(3) concentrations in the broiler house, energy consumption and cost of heating, and production performance of broilers were evaluated. Results showed that the final BW gain significantly (P heating system did not affect the mortality of chicks during the first 4 wk of the experimental period, but the mortality markedly increased in the conventional broiler house during the last wk of the experiment. Oxygen content in the broiler house during the experimental period was not affected by the heating system, but the CO(2) and NH(3) contents significantly increased (P heating the GHP house was significantly lower (P heating system for broiler chickens.

    Full Text Available This study was made to investigate the long-term effects of different floor housing systems on the welfare of fast-growing broilers. The experiment was performed on 210-day-old fast-growing hybrid male chickens with identical conditions until 47 days of age. Animal-based welfare parameters were measured to investigate the welfare level in the group housed on deep litter, a litter and slat system, and a slatted floor, with five replicates for each group. Results showed that the main welfare indicators in live birds, such breast dirtiness, plumage score, footpad lesion, and hock burn lesion, were negatively affected in broilers kept on conventional deep-litter floor housing. But hemorrhage or lesion scores of the breast and shoulder of broilers in slat floor housing were found to be significantly greater than in conventional deep litter as a result of a heavy body weight at a greater slaughter age (p < 0.05. Pathologically, the prevalence of footpad and hock joint dermatitis was very high in the deep-litter housing system. Femoral head necrosis was not observed in any floor housing group. The results indicated that keeping broilers on a slat flooring system is preferable for younger slaughter ages and for a lighter slaughter weight. When considering the relationship between animal welfare and production economy, moving from one floor house system to another floor housing system should be carefully weighted in future decisions. Moreover, further investigations are needed in order to examine the incidence of joint and bone problems with muscle inflammation in heavier broilers in commercial conditions.

    Full Text Available Since the colonisation era, the immigrants from mainland China (and now their descendents dominate the Malaysian housing industry. Their high entrepreneurial ethics stimulated early venture in all economic sectors to become dominant in business. To increase the participation of indigenous entrepreneurs in economic activities, Malaysia has practiced its own version of the affirmative policy since the 1970s which is known as National Economic Policy (NEP. Unlike other economic sectors such as construction, manufacturing and agricultural, the government has not provided special assistance (other than those that are generic in nature for the indigenous populace to penetrate and thrive in housing development. As a consequence, their participation in this sector is conspicuous by their absence. A study was conducted to look into the involvement of indigenous housing developers in housing industry. Data was collected through postal questionnaires followed by face-to-face interviews. The discussion on the data analysis is presented together with interview findings.

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

    Papini, Marta; Salazar, Margarita; Nielsen, Jens

    The field of industrial biotechnology is expanding rapidly as the chemical industry is looking towards more sustainable production of chemicals that can be used as fuels or building blocks for production of solvents and materials. In connection with the development of sustainable bioprocesses, it is a major challenge to design and develop efficient cell factories that can ensure cost efficient conversion of the raw material into the chemical of interest. This is achieved through metabolic engineering, where the metabolism of the cell factory is engineered such that there is an efficient conversion of sugars, the typical raw materials in the fermentation industry, into the desired product. However, engineering of cellular metabolism is often challenging due to the complex regulation that has evolved in connection with adaptation of the different microorganisms to their ecological niches. In order to map these regulatory structures and further de-regulate them, as well as identify ingenious metabolic engineering strategies that full-fill mass balance constraints, tools from systems biology can be applied. This involves both high-throughput analysis tools like transcriptome, proteome and metabolome analysis, as well as the use of mathematical modeling to simulate the phenotypes resulting from the different metabolic engineering strategies. It is in fact expected that systems biology may substantially improve the process of cell factory development, and we therefore propose the term Industrial Systems Biology for how systems biology will enhance the development of industrial biotechnology for sustainable chemical production.

    Full Text Available Housing is a basic need and a human right. The role that housing plays in the social and economic development of a country cannot be underestimated. Interventions in housing by government are widely acknowledged as one of the ways by which the social aspect of the life of the citizenry can be impacted especially through mass housing otherwise called social housing. This paper aims to examine the various potentials in the housing sector in order to enhance the delivery of more housing to Nigerians. A survey research approach was used in the study. Descriptive analysis was employed to explain the potentials in the housing sector. Housing deficit in Nigeria currently stands at about 17 million units. Efforts to meet and rectify the deficit will need a concerted effort of individuals and government. It requires unleashing the potentials in the housing sector to stimulate growth in the economy, thereby diversifying the economy from the mono to a multi sector economy. Interventions of governments at all levels as well as the involvement of informal sector in the housing sector will have a multiplier effect. It will generate multiple employment opportunities which will in turn stimulate the economy through the circulation of money in the system. The paper noted that interventions in housing sector will stimulate industries in the production of local building materials. Additionally, ailing companies will be revitalized, thereby improving the standard of living of the citizens. The paper concludes that strengthening and repositioning of agencies such as the Federal Mortgage Bank of Nigeria, Real Estate Developers Association of Nigeria, Nigeria Mortgage Refinance Company, will accelerate the release of the potentials in the housing sector and thereby enhance the delivery of affordable houses for Nigerians.

    Full Text Available The article is dedicated to the development of models for management of housing and communal services of a city on the basis of the system approach and simulation modeling. A review of the existing models of urban systems is carried out, their advantages and disadvantages are shown. With the use of the methods of simulation and scenario modeling, a simulation model for management of housing and communal services of a city has been developed, which makes it possible to predict the dynamics of the main socio-economic indicators of development of a city. On the basis of the model, the forecast indicators were simulated according to various scenarios for distributing financial resources for the renovation and maintenance of housing facilities of a city. The main criterion for effectiveness of the scenarios is the level of housing provision for the population. The models built can be used for making managerial decisions by local government authorities as well as in elaborating programs for the urban social and economic development.

    2007-06-15

    In this study, a Swedish house built in 1974, heated with resistance heaters was analysed. Different options for changing the heating system and electricity production were compared for this type of detached house, assuming coal-based electricity production as a reference. Changes in the fuel used, the electricity production technology, the end-use heating technology and the heat demand were analysed. The aim was to show how these different parts of the energy system interact and to evaluate the cost-effectiveness of reducing CO{sub 2} emission and primary energy use by different combinations of changes. The results showed that the CO{sub 2} emission and primary energy use could be reduced by 95 and 70%, respectively, without increased heating costs in a national economic perspective. The choice of end-use heating system had a greater influence than the energy conservation measures on the parameters studied. The energy conservation measures were less cost-effective in combination with the more energy-efficient heating systems, although the fact that they reduced the heat demand, and thus also the investment cost of the new heating system, was taken into account.

    The objective of this Industrial Cost Assessment Task for ITER Tritium Plant System consists of providing and order of magnitude cost estimate for the following major subsystems, as outlined in the Scope of Task Agreement and Work Program: water distillation (WD) system, vapour phase catalytic exchange (VPCE) system and the isotope separation system (ISS). The methodology adopted in preparing the order of magnitude cost estimate for the above three subsystems of the ITER tritium plant system is based on building the estimate from the ground up, starting with equipment cost estimates, and adding labour activities separately for engineering, fabrication, assembly, testing installation commissioning, etc. The estimate has been developed assuming that the systems are to be engineered, fabricated and constructed in Canada, (to comply with the Codes, Standards, QA and Seismic Classification applicable in Canada) since information on ITER siting is not currently available. The estimate is based on Ontario Hydro in house cost data on similar systems and equipment, such as the heavy water upgrading plants. The cost estimates are not based on quotations from suppliers for specific ITER components, since this would require completion of detailed design and specifications. 4 refs., 9 tabs., 7 figs

    International Nuclear Information System (INIS)

    Rabany, M.

    1992-01-01

    Modern industrial process control systems have developed to meet the needs of industry to increase the production while decreasing the costs. Although particle accelerators designers have pioneered in control systems during the seventies, it has now become possible to them to profit of industrial solutions in substitution of, or in complement with the more traditional home made ones. Adapting and integrating such industrial systems to the accelerator control area will certainly benefit to the field in terms of finance, human resources and technical facilities offered off-the-shelf by the widely experienced industrial controls community; however this cannot be done without slightly affecting the overall accelerator control architecture. The paper briefly describes the industrial controls arena and takes example on an industrial process control system recently installed at CERN to discuss in detail the related choices and issues.

    Full Text Available The production system using cages is a highly polemical issue in Europe, because of the space restriction imposed to laying hens. It is considered that the cage system might compromise important comfort movements, welfare and egg quality. This study evaluated egg quality and welfare of two strains of hens housed in a conventional system (battery laying cages or litter system with nest and perches, and submitted to heat stress or comfort conditions. Two groups of 20 birds (10 Hy-line W36 and 10 Hy-line Brown were submitted to two environmental conditions (26°C and 60% RH or 35°C and 70% RH and two housing systems (cages or litter in the early production phase. Egg quality was analyzed based on egg weight, eggshell thickness, specific gravity, and Haugh units. Yolk and shell contamination by Salmonella sp was also assessed. A significant (p<0.05 reduction in quality parameters was observed in eggs produced by laying hens under heat stress, mainly in the birds housed in cages.

    The weaning process has been identified as associated with potential psychological, nutritional and physiological stressors on both dam and her young. These stressors are often stressful for the young. Ten sucker camel calves were weaned using calf-dam on and suckling off weaning system (calves were kept with their dams at all times during weaning process and prevented from suckling) under two housing systems, 6 calves in group housing system (G) and 4 calves in individually housing system (I). Half of calves in each housing system were supplemented with probiotics (treated, P), while the other was not-supplemented with probiotics (control, C). This study was carried out at Maryout Research Station of the Desert Research Center, 35 km to southwest of Alexandria, Egypt. Calves were weaned at 280 days of age with initial live body weight (LBW) of 236.76±0.224 kg. The duration of the study was 35 days and divided into five weeks; one week served as pre-weaning followed by four weeks served as post-weaning period (calves were in treatments). Calves and their dams were used to estimate the effects of weaning stress, housing systems (group, G vs. individually, I) and probiotics supplementation on the productive performance, cortisol (COR) and thyroid hormones (T 3 and T 4 ) concentrations of camel calves (Camelus dromedaries). No measurements were done on the dams. The results indicated that, regardless the effect of housing system and Abdel-Fattah et al., J. Rad. Res. Appl. Sci., Vol. 4, No. 4(B) (2011) 1292 probiotics supplementation, weaning stress declined LBW -0.89% at d 7 post weaning. Concerned housing system effect, group-housed calves and individually-housed calves lost -0.36 and -1.43% of their body weights, respectively on d 7 post-weaning and they recovered their weaning weight (d 0 ) on d 14 post-weaning period (2.45 and 0.57%). Neither group housing system nor probiotics supplementation prevented the weight lost resulted by weaning stress during the first

    The LIGHTEnUP Analysis Tool (Lifecycle Industry GreenHouse gas, Technology and Energy through the Use Phase) has been developed for The United States Department of Energy’s (U.S. DOE) Advanced Manufacturing Office (AMO) to forecast both the manufacturing sector and product life-cycle energy consumption implications of manufactured products across the U.S. economy. The tool architecture incorporates publicly available historic and projection datasets of U.S. economy-wide energy use including manufacturing, buildings operations, electricity generation and transportation. The tool requires minimal inputs to define alternate scenarios to business-as-usual projection data. The tool is not an optimization or equilibrium model and therefore does not select technologies or deployment scenarios endogenously. Instead, inputs are developed exogenous to the tool by the user to reflect detailed engineering calculations, future targets and goals, or creative insights. The tool projects the scenario’s energy, CO2 emissions, and energy expenditure (i.e., economic spending to purchase energy) implications and provides documentation to communicate results. The tool provides a transparent and uniform system of comparing manufacturing and use-phase impacts of technologies. The tool allows the user to create multiple scenarios that can reflect a range of possible future outcomes. However, reasonable scenarios require careful attention to assumptions and details about the future. This tool is part of an emerging set of AMO’s life cycle analysis (LCA) tool such as the Material Flows the Industry (MFI) tool, and the Additive Manufacturing LCA tool.

  18. Passive houses in Norway

    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.

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

    The Safety Pharmacology Society (SPS) and National Centre for the Replacement, Refinement & Reduction of Animals in Research (NC3Rs) conducted a survey and workshop in 2015 to define current industry practices relating to housing of non-rodents during telemetry recordings in safety pharmacology and toxicology studies. The aim was to share experiences, canvas opinion on the study procedures/designs that could be used and explore the barriers to social housing. Thirty-nine sites, either running studies (Sponsors or Contract Research Organisations, CROs) and/or outsourcing work responded to the survey (51% from Europe; 41% from USA). During safety pharmacology studies, 84, 67 and 100% of respondents socially house dogs, minipigs and non-human primates (NHPs) respectively on non-recording days. However, on recording days 20, 20 and 33% of respondents socially house the animals, respectively. The main barriers for social housing were limitations in the recording equipment used, study design and animal temperament/activity. During toxicology studies, 94, 100 and 100% of respondents socially house dogs, minipigs and NHPs respectively on non-recording days. However, on recording days 31, 25 and 50% of respondents socially house the animals, respectively. The main barriers for social housing were risk of damage to and limitations in the recording equipment used, food consumption recording and temperament/activity of the animals. Although the majority of the industry does not yet socially house animals during telemetry recordings in safety pharmacology and toxicology studies, there is support to implement this refinement. Continued discussions, sharing of best practice and data from companies already socially housing, combined with technology improvements and investments in infrastructure are required to maintain the forward momentum of this refinement across the industry.

    Sustainable sanitation is an approach for more ecological and sustainable water resources management. In this paper, we proposed one of the new integrated waste treatment systems: an "sustainable sanitation system" that includes separation of the black water from water system by a non-flushing toilet (bio-toilet), and a gray water treatment based on a biological and ecological concept. Sustainable sanitation system also converts the domestic waste to soil conditioners and fertilizers, for farmland use. As one of the case studies, Environmentally Symbiotic Housing in which people actually live using the bio-toilet for the black water treatment and the household wastewater treatment facility for the gray water was introduced. The availability of this system was investigated by analyzing the sawdust used in the bio-toilet and the quality of the effluent in the household wastewater treatment facility. As the result, the water content of the sawdust did not exceed 60% in any of the sampling points and the BOD and COD of the effluent of the household wastewater treatment facility were below 10 and 20 mg/L respectively, due to the low loading. Compared to the pollution load on the water environment created by the conventional system, it was found that the effluent of the house has a lower load than the tertiary treatment and the volume of the water consumption is 75% of the conventional system.

    Full Text Available The American and Romanian house market has imposed harmonious and comfortable living in ecological houses whose building does not affect the environment. The implementation of modern and efficient building of long-term sustainable houses has resulted in a new ecological building technology by the Wood Framing System which is developed and applied on a large scale in the US. This system is a cheap and accessible method to build houses and preserve them in time, as well as provide all the comfort demands. Also, the houses built within this system are adapted to any architecture style (traditional, contemporary, and futurist.The house structures built within the Wood Framing System are conspicuous through the optimum use of the wooden material, resistance, stability, ductility, low weight which thus reduces the earthquake impact, durability, high thermal comfort, competitive price. At the same time, the building time on the site is up to 70% lower, compared with the brick-based houses.Within the framing system, a wooden-structure house provides important advantages, and thus has become of interest on the Romanian market.

    Full Text Available The Green Core House is a construction concept with low environmental impact, having as main central element a greenhouse. The greenhouse has the innovative role to use the biomass energy provided by plants to save energy. Although it is the central piece, the greenhouse is not the most innovative part of the Green Core House, but the whole building ensemble because it integrates many other sustainable systems as "waste purification systems", "transparent photovoltaic panels" or "double skin façades".

    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.

    Full Text Available In this 21st century, the world is moving more and more into the information economy; and information held by organization's information systems is among the most valuable assets in the organization's care and is considered a critical resource, enabling the organizations to achieve their strategic objectives. In-house developed information systems meant to enable organizations to achieve their strategic objectives, are on the increase and security has become a major concern in recent years. Hackers are using new techniques to gain access to sensitive data, disable information systems and administer other malicious activities aimed at the information systems. The need to secure an information system is imperative for use in today's world. Until recently, information systems security was an afterthought; developers were typically focused on functionality and features, waiting to implement security at the end of development. This approach to information systems security has proven to be disastrous because vulnerabilities have gone undetected allowing information systems to be attacked and damaged. A survey done in three (3 organizations in Tanzania has proved that most of the information systems developers have drawn their background from traditional systems development without the sense of implementing security in the early stage of information system development. This paper attempts to identify in-house developed information system's security deficiencies and related risks to organizations, the paper also attempt to establish technique that can be used to detect those deficiencies. Lastly the paper provide guidance that can be used by organizations to mitigate the risks.

    Feather pecking and high mortality levels are significant welfare problems in non-cage housing systems for laying hens. The aim of this study was to identify husbandry-related risk factors for feather damage, mortality, and egg laying performance in laying hens housed in the multi-tier non-cage housing systems known as aviaries. Factors tested included type of system flooring, degree of red mite infestation, and access to free-range areas. Information on housing characteristics, management, and performance in Belgian aviaries (N=47 flocks) were obtained from a questionnaire, farm records, and farm visits. Plumage condition and pecking wounds were scored in 50 randomly selected 60-week-old hens per flock. Associations between plumage condition, wounds, performance, mortality, and possible risk factors were investigated using a linear model with a stepwise model selection procedure. Many flocks exhibited a poor plumage condition and a high prevalence of wounds, with considerable variation between flocks. Better plumage condition was found in wire mesh aviaries (Pfeather cover had lower levels of mortality (Pnest perches. Wire mesh flooring in particular seems to have several health, welfare, and performance benefits in comparison to plastic slats, possibly related to decreased feather pecking, better hygiene, and fewer red mite infestations. This suggests that adjustments to the aviary housing design may further improve laying hen welfare and performance. © 2015 Poultry Science Association Inc.

    Full Text Available Sustainable housing has been subject to research, practice and policy making for some considerable time. More recently attention has been drawn to the separate problem of declining affordability in housing. This paper describes research aimed at developing an assessment framework for both affordability and sustainability as part of the effort to incorporate both of these features into new housing projects. The research has a particular focus on developments aimed at urban densification. Background literature on both affordability and sustainability is reviewed as well as emerging schemes aimed at dealing with both aspects of housing developments. Performance indicators are identified and these are incorporated in an interim assessment framework which is tested using a group of industry experts. The research has highlighted areas where further development is required to attain quantitative assessments of affordable and sustainable housing developments

    Full Text Available Gas production in broiler houses and their emissions are closely related to the microclimate established inside the house according to air temperature, humidity, and velocity. Therefore, the internal house environment is influenced by building typology and ventilation system. The objective of the present study was to evaluate ammonia emission rates in broiler houses equipped with different ventilation systems (negative or positive pressure and litter conditions (new or built-up. The environment of six commercial broiler houses was evaluated internal and external NH3 concentrations. Ventilation rates were recorded to estimate ammonia emission rates. The efficiency of circulation and exhaust fans was assessed, and higher ventilation rates were determined in negative-pressure houses due to the higher flow of the fans. Houses with new litter increased ammonia emission rates along the rearing period, indicating the relationship between gas emissions, bird age and ventilation rates, and presented a typical curve of NH3 emission increase. Negative-pressure houses with built-up litter presented higher emission rates during the first rearing week due to the high NH3 concentration during the brooding period, when the ventilation rates required to maintain chick thermal comfort are low. Although the results of the present study indicate an advantage of the positive-pressure systems as to gas emissions, further research is needed reduce gas emissions in broiler houses with negative-pressure systems.

    The weaning process has been identified as associated with potential psychological, nutritional and physiological stressors on both dam and her young. These stressors are often stressful for the young. Ten sucker camel calves were weaned using calf-dam on and suckling off weaning system (calves were kept with their dams at all times during weaning process and prevented from suckling) under two housing systems, 6 calves in group housing system (G) and 4 calves in individually housing system (I). Half of calves in each housing system were supplemented with probiotics (treated, P), while the other was not-supplemented with probiotics (control, C). This study was carried out at Maryout Research Station of the Desert Research Center, 35 km to southwest of Alexandria, Egypt. Calves were weaned at 280 days of age with initial live body weight (LBW) of 236.76{+-}0.224 kg. The duration of the study was 35 days and divided into five weeks; one week served as pre-weaning followed by four weeks served as post-weaning period (calves were in treatments). Calves and their dams were used to estimate the effects of weaning stress, housing systems (group, G vs. individually, I) and probiotics supplementation on the productive performance, cortisol (COR) and thyroid hormones (T{sub 3} and T{sub 4}) concentrations of camel calves (Camelus dromedaries). No measurements were done on the dams. The results indicated that, regardless the effect of housing system and Abdel-Fattah et al., J. Rad. Res. Appl. Sci., Vol. 4, No. 4(B) (2011) 1292 probiotics supplementation, weaning stress declined LBW -0.89% at d{sub 7} post weaning. Concerned housing system effect, group-housed calves and individually-housed calves lost -0.36 and -1.43% of their body weights, respectively on d{sub 7} post-weaning and they recovered their weaning weight (d{sub 0}) on d{sub 14} post-weaning period (2.45 and 0.57%).

    Miscevic, Lj.

    2005-01-01

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

    2003-01-01

    This paper explores how climate change could affect the UK house-building sector, focusing on the question of how companies can adapt to changing climatic conditions. It presents the results of in-depth interviews in five house-building companies in the UK. We start from the assumption that climate change is only one driver among many, including technological innovation, shifting consumer expectations and changing regulation, that the industry faces. This approach draws on insights that are well established in the management and innovation literatures, but have often been neglected in studies of climate change. We report research about the perceptions of house builders about future impacts of climate change, potential adaptation measures that may be open to them and their ability to carry out these measures. The paper draws conclusions about the challenges that climate change presents to the UK house building industry. (author)

    1999-01-01

    New turnkey data acquisition systems purchased from industry are being integrated into CERN's Technical Data Server. The short time available for system integration and the large amount of data per system require a standard and modular design. Four different integration layers have been defined in order to easily 'plug in' industrial systems. The first layer allows the integration of the equipment at the digital I/O port or fieldbus (Profibus-DP) level. A second layer permits the integration of PLCs (Siemens S5, S7 and Telemecanique); a third layer integrates equipment drivers. The fourth layer integrates turnkey mimic diagrams in the TCR operator console. The second and third layers use two new event-driven protocols based on TCP/IP. Using this structure, new systems are integrated in the data transmission chain, the layer at which they are integrated depending only on their integration capabilities.

    2007-09-01

    The application of computational fluid dynamics (CFD) in the agricultural industry is becoming ever more important. Over the years, the versatility, accuracy and user-friendliness offered by CFD has led to its increased take-up by the agricultural engineering community. Now CFD is regularly employed to solve environmental problems of greenhouses and animal production facilities. However, due to a combination of increased computer efficacy and advanced numerical techniques, the realism of these simulations has only been enhanced in recent years. This study provides a state-of-the-art review of CFD, its current applications in the design of ventilation systems for agricultural production systems, and the outstanding challenging issues that confront CFD modellers. The current status of greenhouse CFD modelling was found to be at a higher standard than that of animal housing, owing to the incorporation of user-defined routines that simulate crop biological responses as a function of local environmental conditions. Nevertheless, the most recent animal housing simulations have addressed this issue and in turn have become more physically realistic.

  8. Exploring the beliefs of Australian prefabricated house builders

    Directory of Open Access Journals (Sweden)

    Dale A Steinhardt

    2016-06-01

    Full Text Available The housing sector accounts for a majority of newly constructed buildings. Prefabrication, defined as the factory construction of houses or significant components, is widely promoted as a means to improve efficiency. This paper focuses on the research questions: RQ1. What are the attitudes of builders towards prefabrication adoption? RQ2. What types of stakeholders do builders believe influence their adoption decisions? RQ3. What types of contextual influences do builders believe impact their adoption decisions? Current prefabrication research has focused on the advantages and disadvantages of prefabrication, without further unpacking the beliefs of stakeholders that underpin them. This paper addresses this gap and increases the understanding of beliefs that can frame interventions to increase the market penetration of prefabrication. Fourteen interviews with Australian prefabricators were undertaken as a Belief Elicitation Study. This qualitative methodology is framed by the Theory of Planned Behaviour (TPB and the Technology Acceptance Model (TAM. Results show that modern high-quality prefabricated housing has struggled to overcome historical stigma; improved construction speed has not and is not likely to translate to reduced totals costs for a majority of firms; and prefabrication adoption has been hindered by an almost completely unsupportive industry infrastructure. Recommendations are made to frame arguments in improving short-term outcomes for an industry driven by practical considerations. Future discourse must focus on cost impacts, financial security and risk reduction. Establishing networks of prefabricators that can build a strong, unified voice for the industry should be prioritised.

    ENGLISH ABSTRACT: A learning management system (LMS is any infrastructure on which e-learning can be built and delivered. In this article two sides of the LMS coin are investigated: On the one side, it is argued that industrial and systems engineering skills are equally relevant for learning systems as for as for any other system. To support this argument, an analogy is drawn between the management of learning systems and the management of manufacturing systems. On the other side of the coin, the educational issues and concerns related to implementing an LMS at the University of Pretoria are investigated by means of a case study in the Industrial Engineering department. It is concluded that the industrial engineering educator is in the unique position of understanding and contributing towards the engineering of the education industry whilst educating the industrial engineer.

    AFRIKAANSE OPSOMMING: ‘n Leerbestuurstelsel (LMS is enige infrastruktuur waarop e-leer gebou en afgelewer kan word. In hierdie artikel word beide kante van die LMS muntstuk ondersoek: Aan die een kant word getoon dat bedryfsingenieursvaardighede en -beginsels ewe toepaslik is op leerstelsels as op vervaardigingstelsels. Om hierdie argument te steun word 'n analogie getrek tussen the bestuur van leerstelsels en die bestuur van vervaardigingstelsels. Aan die ander kant van die muntstuk word die opvoedkundige aspekte verbonde aan die implementering van ‘n leerbestuurstelsel (LMS aan die Universiteit van Pretoria ondersoek aan die hand van ‘n gevallestudie in die Bedryfsingenieursdepartment. Die gevolgtrekking word gemaak dat die bedryfsingenieurs-opleier in 'n unieke posisie is om die opleidingsindustrie te begryp en by dra tot the ontwikkeling daarvan terwyl die bedryfsingenieur opgelei word.

  11. Evaluation of Mass Housing at the Pre-Design Stage

    2014-09-01

    Full Text Available Throughout history, housing has been a central problem in the lives of human beings. Housing, which includes shelter for family and functional volumes that meet social needs, used to be built specifically for the family. The concept of “Mass Housing” entered the field of architecture as a result of the industrial revolution, when lavish Renaissance housing gradually turned into housing for workers. Today, the demand for housing cannot keep up with fast-growing populations. Besides the quantitative problems of housing production, there is the ever- growing problem of quality, the solution to which lies with designer architects. On this issue of quality, Post Occupation Evaluation (POE studies, conducted to provide data for upcoming designs, and certificate evaluations like LEED and BREEAM, aimed at measuring energy performance effectiveness of new buildings, mostly involve measurements of usage of the building envelope, environmental relations, facilities and usage of natural resources. None prioritize the form and function issues of spatial usage in architectural designs. This study proposes a method that enables spatial and functional measurement and assessment at the project stage. The suggested spatial performance measurement–assessment system has three stages. In the first stage, the standards and usage criteria to be used as reference in the assessment are defined. The second stage suggests using the SAR analysis approach, and the third stage is about conducting “Spatial Performance Assessment”. Here, the common denominator of “User System” and “Building System”, which shares characteristic design criteria “Form, Function,Construction” is established and by this way, testing and assessing the subject of study becomes possible. With these assessments, by providing digitalization of spatial performance with proportional values, it is believed that a database for the provision of statistical information may be established.

    To propose a theoretical based model approach to address the nursing shortage problem of recruiting qualified applicants. Vital industries such as nursing and trucking face a large labour shortage. A literature review focusing on recruitment and realistic job previews examines relevant theories and an indication of the focus of similar research. Game theory illustrates cooperative and competitive recruitment strategies in vital industries. Proposition and model development where cooperative or competitive strategies for recruitment can either increase or decrease the employee applicant pool. Institutional theory states that firms within a population become isomorphic in nature. Firms employing cooperative or competitive strategies for recruitment can change organisational practices through isomorphic processes. Industries facing a labour market shortage using cooperative strategy will use realistic job previews accurately to disseminate information about industry jobs. Realistic job previews will increase the applicant pool through individuals self-selecting into, rather than out of, the applicant pool. Recruitment in the nursing industry has been examined at the individual applicant and organisational level, yet the overall industry has been ignored. As nursing shortages continue, viewing recruitment at the macro level (the overall industry) is appropriate. Game theory as proposed provides opportunities for current research at the industry level. © 2015 John Wiley & Sons Ltd.

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

    2013-01-01

    Background Tie-stall housing of dairy cows is used extensively worldwide, despite of the welfare concerns regarding the restriction of voluntary movement and limitation of expression of the cows’ natural behaviour. The aim of this study was to compare the welfare quality of dairy cows kept in two types of tie-stall housing systems: with regular outdoor exercise and without access to exercise. In addition, the study investigated the relationship between different welfare measures of dairy cows kept in tie-stalls. Methods 3,192 lactating cows were assessed using the Welfare Quality® assessment protocol for cattle in 80 commercial dairy farms, half of the farms providing outdoor access for the animals to exercise. The descriptive statistical indicators were determined for the assessed measures and for the welfare criteria and principle scores. The data obtained in the two housing types were compared and the correlation coefficients were calculated between the different welfare measures. Results The significant differences found between the two housing systems for the majority of the animal based measures indicate the positive effect of exercise on the welfare of tethered cows. Many of the animal welfare parameters correlated with each other. For the farms allowing the cows’ turnout in a paddock, pasture or both, the mean scores for the welfare criteria and principles were higher than for the farms with permanent tethering of the cows, except the criteria absence of prolonged hunger and expression of social behaviours. The lowest scores were obtained for the criterion positive emotional state, in both housing systems. With regard to the overall classification, none of the farms were considered excellent. In the not classified category were only farms with all-year-round tethering of the animals and in the enhanced category only farms where the cows had outdoor access. Conclusions The welfare quality of the investigated dairy cows was significantly better in the

    Pork is very important for people in daily life. Quality of livestock environment is closely related to the growth of animals. To improve environmental quality, the paper designed an electronic worker service system of the pig house based on ATmega16, which consisted of 6 detection modules, wireless data collecting, GSM, time circuit, display, anti-th alarm and music player, etc. A small LAN was constructed by wireless transceiver module to test and collect data of temperature, humidity and harmful gas concentration in the pig house. If one detection point exists that harmful pollutant gases concentration exceeds the standard value, GSM module took a message for livestock farmers, so that farmers can promptly arrive at the pig house to ventilate or deal with manure in the pig house, which can effectively prevent from bad things. Time of pyroelectric detector deployment can be freely set, and intrusion information was timely sent to the users. The anti-th alarm function was achieved by the auxiliary light. The music playing module is open by timer module in order to soothing pigs' life state. All are suitable for small farms and can save human 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)

    Industrial control system manufacturers supply the building blocks for the control of industrial equipment or specific process control applications. Although the laboratory environment is different in many aspects (prototyping, evolution and frequent reconfiguration), the use of these building blocks remain attractive because of their general purpose nature, their cost and the large spectrum of available types. In this paper we present three projects which have been implemented using both industrial control system building blocks (PLCs, controllers, digital and analogue plug-in I/O cards) and commercial software packages (LabView and VisualBasic) for the man-machine interface, the data acquisition and archiving, and the process control. This approach has proved to be economical, easy and fast to implement. ((orig.))

    Prostate Imaging-Reporting and Data System v. 2 (PI-RADSv2) provides standardized nomenclature for interpretation of prostate multiparametric MRI (mpMRI). Inclusion of additional features for categorization may provide benefit to stratification of disease. To prospectively compare PI-RADSv2 to a qualitative in-house system for detecting prostate cancer on mpMRI. Prospective. In all, 338 patients who underwent mpMRI May 2015-May 2016, with subsequent MRI/transrectal ultrasound fusion-guided biopsy. 3T mpMRI (T 2 W, diffusion-weighted [DW], apparent diffusion coefficient [ADC] map, b-2000 DWI acquisition, and dynamic contrast-enhanced [DCE] MRI). One genitourinary radiologist prospectively read mpMRIs using both in-house and PI-RADSv2 5-category systems. In lesion-based analysis, overall and clinically significant (CS) tumor detection rates (TDR) were calculated for all PI-RADSv2 and in-house categories. The ability of each scoring system to detect cancer was assessed by area under receiver operator characteristic curve (AUC). Within each PI-RADSv2 category, lesions were further stratified by their in-house categories to determine if TDRs can be increased by combining features of both systems. In 338 patients (median prostate-specific antigen [PSA] 6.5 [0.6-113.6] ng/mL; age 64 [44-84] years), 733 lesions were identified (47% tumor-positive). Predictive abilities of both systems were comparable for all (AUC 76-78%) and CS cancers (AUCs 79%). The in-house system had higher overall and CS TDRs than PI-RADSv2 for categories 3 and 4 (P house 65%, PI-RADSv2 22.1%). For lesions categorized as PI-RADSv2 = 4, characterization of suspicious/indeterminate extraprostatic extension (EPE) and equivocal findings across all mpMRI sequences contributed to significantly different TDRs for both systems (TDR range 19-75%, P < 0.05). PI-RADSv2 behaves similarly to an existing validated system that relies on the number of sequences on which a lesion is seen. This prospective

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

    Industrial energy management systems, which comprise software solutions, upfront services, and ongoing monitoring and management, enable industrial companies to actively manage their energy consumption and energy procurement activities. Energy management systems are usually tailored to the specific industrial needs but may offer limited functionalities, mostly as a result of different identified gaps (process simplifications, improper measurement points, a lack of motivation, etc.). A survey was conducted in order to analyse the gaps and use of energy management systems in Slovenian industry. The results of the survey presented in this paper demonstrate that the use of energy management systems in industry is recognised as a potential competitive advantage by most of the addressed companies. Furthermore, motivation was highlighted as an important prerequisite for process and structural improvements and reported to be thus far insufficiently addressed. Furthermore, the importance of strong cooperation with actors at different levels of industry, namely the executive and shop floor levels, is addressed. In the conclusion, possibilities for new opportunities in the exploitation of energy efficiency through the use of industrial energy management systems are discussed. - Highlights: • Investigating gaps and evaluation of EMS use in Slovenian industry. • Analysis based on the developed self-assessment tool 3EMT. • Existing EMS do not include all the requirements for the industrial operations. • Constructive cooperation between all stakeholders is of crucial importance.

    Private house systems are investigated for system constitution, detailed design is drawn, and a model house is built. For system control and protection, the power conversion unit is provided with a control which functions to constantly maximize the output. The power conversion unit without an internal oscillator is equipped with another control which functions to output single-phase AC power coincident with the commercial system in voltage and frequency when it is interconnected with the system. The power conversion unit is so designed that it is automatically stopped for the prevention of reverse voltage imposition on the commercial system in case of interruption in the commercial system. In the study of roof panel type solar cells, real-size panels are designed and fabricated, capable of a total of 3kWp. In the study of element devices, a real-size conversion unit is experimentally built and tested in combination with a rectifier and solar cells, and it is found that the unit functions as expected. A model house is designed incorporating the results of the above-said research, and is built in the precinct of a laboratory of the Fuji Electric Co., Ltd. (NEDO)

    Full Text Available Climate change and sustainability legislation in recent years has led to significant changes in construction approaches in the UK housing sector. This has resulted in the adoption of new building typologies, including the German Passivhaus (Passive House standard. This standard aims to improve occupant comfort and energy efficiency, potentially changing the ways in which homes operate and how occupants interact with them. With increasing construction of low energy dwellings, there is an emerging gap in knowledge in relation to occupant health and wellbeing, thermal comfort, and indoor air quality (IAQ. Using data collected from a two year Building Performance Evaluation (BPE study funded by Innovate UK, the environmental data (temperature, relative humidity and carbon dioxide concentrations from five Certified Passive House homes in Scotland was compared. The results demonstrate problems with overheating with peak temperatures exceeding 30 °C. Imbalanced mechanical ventilation with heat recovery (MVHR systems were identified in 80% of the dwellings and inadequate IAQ was found due to poor ventilation. Only one of the Passive Houses studied exhibited thermal conditions and IAQ which were, on the whole within Passive House parameters. This paper outlines the insights and the main issues of Scottish Passive House in the broader context of sustainability.

    1990-01-01

    This paper reports on expert systems which have reached a level of maturity where they offer considerable benefits for the nuclear utility industry. The ability of expert systems to enhance expertise makes them an important tool for the nuclear utility industry in the areas of engineering, operations and maintenance. Benefits of expert system applications include comprehensive and consistent reasoning, reduction of time required for activities, retention of human expertise and ability to utilize multiple experts knowledge for an activity. The Electric Power Research Institute (EPRI) has been performing four basic activities to help the nuclear industry take advantage of this expert system technology. The first is the development of expert system building tools which are tailored to nuclear utility industry applications. The second is the development of expert system applications. The third is work in developing a methodology for verification and validation of expert systems. The last is technology transfer activities to help the nuclear utility industry benefit from expert systems. The purpose of this paper is to describe the EPRI activities

  20. 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.

  1. Influence of age and housing systems on properties of tibia and humerus of Lohmann White hens1: Bone properties of laying hens in commercial housing systems.

    Regmi, P; Nelson, N; Haut, R C; Orth, M W; Karcher, D M

    2017-10-01

    This study was aimed at analyzing bone properties of Lohmann White hens in different commercial housing systems at various points throughout production. Pullets reared in conventional cages (CC) were either continued in CC or moved to enriched colony cages (EN) at 19 weeks. Pullets reared in cage-free aviaries (AV) were moved to AV hen houses. Bone samples were collected from 60 hens at each of 18 and 72 wk and 30 hens at 26 and 56 wk from each housing system. Left tibiae and humeri were broken under uniform bending to analyze mechanical properties. Cortical geometry was analyzed using digital calipers at the fracture site. Contralateral tibiae and humeri were used for measurement of ash percentage. AV pullets' humeri had 41% greater cortical areas, and tibiae had 19% greater cortical areas than the CC pullets (P < 0.05). Average humeri diameter was greater in AV pullets than in CC pullets (P < 0.05), whereas the tibiae outer dimensions were similar. Aviary pullet bones had greater stiffness (31 and 7% greater for tibiae and humeri, respectively) and second moment of inertia (43 and 13% greater for tibiae and humeri, respectively) than CC pullets (P < 0.05). The differences between bones of AV and CC hens persisted throughout the laying cycle. Moving CC pullets to EN resulted in decreased endosteal resorption in humeri, evident by a 7.5% greater cortical area in the EN hens (P < 0.05). Whole-bone breaking strength did not change with age. Stiffness increased with age, while energy to failure decreased in both the tibiae and humeri. These results indicated that tibiae and humeri of laying hens become stiffer but lose toughness and become brittle with age. Furthermore, AV and EN systems can bring positive changes in mechanical and structural properties that are more pronounced in the humerus than the tibia. © 2017 Poultry Science Association Inc.

    Full Text Available In the past years, in Sicily, goats of the Girgentana breed have decreased so drastically in number that they risked extinction. Among the causes, particular blame can be laid at the traditional housing system, in which the goats, after coming back from pasture, were tethered in individual wooden stalls. Such a system is still considered necessary by breeders in order to avoid aggressive and harmful behaviour on the part of the animals, due to the presence of their long horns (Giaccone et al., 1994. This belief negatively interferes with the action recently initiated for the recovery and regeneration of the breed (Portolano et al., 2002; in fact, the tie stalls housing, increasing manpower, limits the increase in size in herds of Girgentana goats...

  7. Air Quality in Alternative Housing Systems may have an Impact on Laying Hen Welfare. Part II—Ammonia

    Directory of Open Access Journals (Sweden)

    Bruce David

    2015-09-01

    Full Text Available The EU ban on conventional barren cages for laying hens from 2012 has improved many aspects of laying hen welfare. The new housing systems allow for the expression of highly-motivated behaviors. However, the systems available for intensive large-scale egg production (e.g., aviaries, floor housing systems, furnished cages may cause other welfare challenges. We have reviewed the literature regarding the health, behavior, production characteristics, and welfare of laying hens when exposed to ammonia in their housing environment. Concentrations of ammonia gas are commonly high in aviaries and floor housing systems in which manure is not regularly removed, whereas they are usually lower in furnished cages. High levels are found during the cold season when ventilation flow is often reduced. Ammonia is a pungent gas, and behavioral studies indicate chickens are averse to the gas. High concentrations of gaseous ammonia can have adverse health effects and, when very high, even influence production performance. The most profound effects seen are the occurrence of lesions in the respiratory tract and keratoconjunctivitis. There is also evidence that high ammonia concentrations predispose poultry to respiratory disease and secondary infections. We conclude that there are animal welfare challenges related to high ammonia levels, and that immediate actions are needed. Development of improved systems and management routines for manure removal and ventilation will be important for the reduction of ammonia levels and hence will contribute to safeguarding hen welfare.

    Sagt, Cees M J

    2013-03-01

    Systems metabolic engineering is based on systems biology, synthetic biology, and evolutionary engineering and is now also applied in industry. Industrial use of systems metabolic engineering focuses on strain and process optimization. Since ambitious yields, titers, productivities, and low costs are key in an industrial setting, the use of effective and robust methods in systems metabolic engineering is becoming very important. Major improvements in the field of proteomics and metabolomics have been crucial in the development of genome-wide approaches in strain and process development. This is accompanied by a rapid increase in DNA sequencing and synthesis capacity. These developments enable the use of systems metabolic engineering in an industrial setting. Industrial systems metabolic engineering can be defined as the combined use of genome-wide genomics, transcriptomics, proteomics, and metabolomics to modify strains or processes. This approach has become very common since the technology for generating large data sets of all levels of the cellular processes has developed quite fast into robust, reliable, and affordable methods. The main challenge and scope of this mini review is how to translate these large data sets in relevant biological leads which can be tested for strain or process improvements. Experimental setup, heterogeneity of the culture, and sample pretreatment are important issues which are easily underrated. In addition, the process of structuring, filtering, and visualization of data is important, but also, the availability of a genetic toolbox and equipment for medium/high-throughput fermentation is a key success factor. For an efficient bioprocess, all the different components in this process have to work together. Therefore, mutual tuning of these components is an important strategy.

  13. Integrated inventory ranking system for oilfield equipment industry

    Jalel Ben Hmida

    2014-01-01

    Full Text Available Purpose: This case study is motivated by the subcontracting problem in an oilfield equipment and service company where the management needs to decide which parts to manufacture in-house when the capacity is not enough to make all required parts. Currently the company is making subcontracting decisions based on management’s experience. Design/methodology/approach: Working with the management, a decision support system (DSS is developed to rank parts by integrating three inventory classification methods considering both quantitative factors such as cost and demand, and qualitative factors such as functionality, efficiency, and quality. The proposed integrated inventory ranking procedure will make use of three classification methods: ABC, FSN, and VED. Findings: An integration mechanism using weights is developed to rank the parts based on the total priority scores. The ranked list generated by the system helps management to identify about 50 critical parts to manufacture in-house. Originality/value: The integration of all three inventory classification techniques into a single system is a unique feature of this research. This is important as it provides a more inclusive, big picture view of the DSS for management’s use in making business decisions.

  14. Electrochemical filtration for turbidity removal in industrial cooling/process water systems

    International Nuclear Information System (INIS)

    Kumbhar, A.G.; Venkateswaran, G.

    2008-01-01

    Water samples of large cooling water reservoirs may look visibly clear and transparent, but still may contain sub-micron size particles at sub-parts-per-million levels. Deposition of these particles on heat exchanger surfaces, reduces the heat transfer efficiency in power industry. In nuclear power plants, additionally it creates radiation exposure problems due to activation of fine metallic turbidity in the reactor core and its subsequent transfer to out-of-core surfaces. Sub-micron filtration creates back high-pressure problem. Zeta filters available commercially are prescribed for separating either positively or negatively charged particles. They are of once-use and throw-type. Precipitation surface modified ion exchangers impart chemical impurities to the system. Thus, sub-micron size and dilute turbidity removal from large volumes of waters such as heat exchanger cooling water in nuclear and power industry poses a problem. Electro deposition of the turbidity causing particles, on porous carbon/graphite felt electrodes, is one of the best suited methods for turbidity removal from large volumes of water due to the filter's high permeability, inertness to the system and regenerability resulting in low waste generation. Initially, active indium turbidity removal from RAPS-1 heavy water moderator system, and microbes removal from heat exchanger cooling lake water of RAPS 1 and 2 were demonstrated with in-house designed and fabricated prototype electrochemical filter (ECF). Subsequently, a larger size, high flow filter was fabricated and deployed for iron turbidity removal from active process waters system of Kaiga Generation Station unit 1 and silica and iron turbidity removal from cooling water pond used for heat exchanger of a high temperature high pressure (HTHP) loop at WSCD, Kalpakkam. The ECF proved its exclusive utility for sub-micron size turbidity removal and microbes removal. ECF maneuverability with potential and current for both positively and

  17. Japanese Social Exclusion and Inclusion from a Housing Perspective

    Directory of Open Access Journals (Sweden)

    Yoshihiro Okamoto

    2016-10-01

    Full Text Available This paper examines conditions of social exclusion and attempts at social inclusion in Japan from a housing perspective. Companies, households and the government have previously supported housing in Japan. However, corporate welfare was withdrawn following the globalization of the economy from the 1990s onwards, support from families and communities declined due to a reduction in household size, and governmental housing support has shifted away from direct support. A reduction in income and unstable work left many people with unstable housing. Certain workers, such as foreigners performing dispatched labour, could not maintain continuous work under the influence of the Lehman Brothers’ bankruptcy in 2008. Household size has shrunk according to changes in the industrial structure, and the number of households that cannot sustain housing is increasing. Such vulnerable households—elderly people, the handicapped, low-income earners and single parents—can become excluded from the rental housing market. On the other hand, governmental measures are promoting local dwellings and maintaining the condition for a dwelling service. Activities, such as local community support of the homeless have been initiated by various Non-profit Organisations (NPOs and NPO activities are increasingly exemplifying measures to achieve social inclusion.

    2017-01-01

    Full Text Available Many researchers considered the quality of management, but the definition of “quality control” in the literature is quite rare. The author’s definition of this concept, whose distinctive features are as follows: management is considered as a system, and its quality is determined by the quality of the elements of the system; management is of high quality, if not only provides function, but also the development of the facility; the quality of management is measured by customer satisfaction. The study authors of market relations in the sphere of housing and communal services helped to define the modern model of management of the industry of housing and communal services, which involves the preservation of state regulation and control and the bringing to market of private operators. Identified the need for further sustained efforts to implement the new economic relations in the system of housing and communal services at all levels of government, which requires further improvement of management. Based on the authors analysis of the methods of evaluation of activities of management companies found that despite their diversity they all have several disadvantages, the main of which is the lack of standard indicators by which to judge to what extent the housing managers of the organization implement the adopted programme. Therefore, the author proposes two sets of criteria (representing the result of control and management efficiency, which will be monitored and evaluated the quality management of the organization.

    2008-12-01

    Full Text Available The aim of this study is to design and test a heating system for piglets in farrowing house by utilising the waste heat from a biogas engine as a heat source. The study was separated into three parts: the study on the biogas combined heat and power plant, the investigation on the properties of the heat panel, and the installation and testing of the heating system. From the experiment, the condition producing 60 kW of electrical power was a proper one, in which electrical efficiency and specific fuel consumption were 14% and 1.22 m3/kWh respectively. Generating both electricity and heat increased the overall efficiency to 37.7% and decreased the specific fuel consumption to 0.45 m3/kWh. The heat panel, which was made of a plastic material, had a thermal conductivity of 0.58 W/mC and the maximum compressive force and operating pressure of 8.1 kN and 0.35 bar respectively. The surface temperature of the panel was dependent on the inlet water temperature. When hot water of 44C was supplied into the farrowing house with room temperature of 26C, the average surface temperature was 33C. The developed heating system could provide heat for 4.3 farrowing houses. The payback period of this project was 2.5 years.

    In the outskirts of Goeteborg, Sweden, twenty terrace houses were constructed throughout 2001. The spectacular thing about these houses is that no traditional heating systems were installed. The commercial's catch phrase is: 'Houses without heating systems'. Following this project from the beginning and through the whole process, including the long planning procedure (between 1997-1999), the professional actors (the initiator, the building proprietor, the contractor and the researchers), come into focus. This is a unique project in Sweden and has not yet had any follow-up developments. The evaluation, mainly including measurements, is being conducted by a research Inst. and will be finalised in 2003. The theoretical approach is as described in socio-technical system and focuses on social and technical components. The point of departure for the study is the social subsystem and the process behind the project which is important in understanding the final outcome. The study focuses on how and why this project was conducted. Initially, one person's ideas, inspired by building projects abroad were crucial. These ideas were then spread to a network constituting of researchers, the building proprietor, the contractor and the builders, and other consultants. The process can be described as a social innovation since a new concept for heating in buildings is introduced by focusing on the planning process and new participating actors.

    Falls, O.B. Jr.; Kleimola, F.W.

    1987-01-01

    A simple definition of the passive containment system is that it is a total safeguards system for light water reactors designed to prevent and contain any accidental release of radioactivity. Its passive features utilize the natural laws of physics and thermodynamics. The system encompasses three basic containments constructed as one integrated structure on the reactor building foundation. The primary containment encloses the reactor pressure vessel and coolant system and passive engineered safety systems and components. Auxiliary containment enclosures house auxiliary systems and components. Secondary containment (the reactor building), housing the primary and auxiliary containment structures, provides a second containment barrier as added defense-in-depth against leakage of radioactivity for all accidents assumed by the industry. The generic features of the passive containment system are applicable to both the boiling water reactors and the pressurized water reactors as standardized features for all power ranges. These features provide for a zero source term, the industry's ultimate safety goal. This paper relates to a four-loop pressurized water reactor

    Science.gov (United States)

    Walker, Michael E; Lv, Zhen; Masanet, Eric

    2013-11-19

    This paper presents estimates for water consumption and steam generation within U.S. manufacturing industries. These estimates were developed through the integration of detailed, industry-level fuel use and operation data with an engineering-based steam system model. The results indicate that industrial steam systems consume approximately 3780 TBTU/yr (3.98 × 10(9) GJ/yr) to generate an estimated 2.9 trillion lb/yr (1.3 trillion kg/yr) of steam. Since a good portion of this steam is injected directly into plant processes, vented, leaked, or removed via blowdown, roughly 354 MGD of freshwater must be introduced to these systems as makeup. This freshwater consumption rate is approximately 11% of that for the entire U.S. manufacturing sector, or the total residential consumption rate of Los Angeles, the second largest city in the U.S. The majority of this consumption (>94%) can be attributed to the food, paper, petroleum refining, and chemicals industries. The results of the analyses presented herein provide previously unavailable detail on water consumption in U.S. industrial steam systems and highlight opportunities for combined energy and water savings.

    2006-01-01

    This paper provides a systematic survey of systems and concepts used in the industrial irradiation of polymers. It consists basically of three parts: in the first part, different types of applications like wires and cables, pipes and engineering plastics are discussed and the associated irradiation systems analyzed and highlighted according their basics modules. These are identified as the radiation source, the product handling system, process control and facility/shielding layout. In the second part, the irradiation process design is reviewed in detail. The discussion starts with the requirement analysis, e.g. the desired polymer parameters and effects, continues with a process development roadmap and concludes with process verification and validation. Special attention is drawn to process control, which plays an important role in industrial irradiation technology. The use of mathematical modeling to facilitate and support process and system design is discussed as well and several examples are given which demonstrate their capabilities. In the third part, the design of a electron beam facility for the irradiation of small plastic parts for the automotive industry is worked out in detail. Besides system and product handling considerations, throughput and economical estimates are provided. The paper concludes with a summary of the design and concept bullets which proved to be important in history and can facilitate new developments which will enhance the potential of industrial polymer irradiation

    Turner, John

    1993-02-01

    The Offshore Oil and Gas Industry in the North Sea has many requirements for three- dimensional measurements in air and underwater. A market audit found that use of conventional photogrammetry was being rejected for many applications because the information was not available fast enough. A development project was set up to replace the photographic cameras with a choice of video or high resolution digital electronic cameras, and the analysis system with a personal computer based image processing system. This solution is now in operation. The paper details the in-house development of the high resolution digital electronic camera and the personal computer based measurement hardware and software. It includes a discussion of the technological parameters, including the method for pixel for pixel correlation within the digital system, camera calibration techniques, the system algorithms, sub-pixel measurement and dimensional accuracy. It introduces the work that was carried out to make the final product acceptable to structural engineers, who now use it to transfer three- dimensional measurements to their CAD systems. It also looks at the work that is being carried out to transform the system into a closed loop control system for underwater robotic manipulators, which includes binary conversion, convolution filtering and tracking functions.

    Van Mierlo, B.; Sprengers, M.

    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

    1989-01-01

    This paper gives results of an EPA study of radon-mitigation alternatives for crawl space houses in several houses in Nashville, TN. Application of one of these alternative mitigation options, suction under a polyethylene membrane, has been successful in significantly reducing radon levels in both the crawl space and the house. The large radon concentrations measured under unvented plastic ground covers and the moisture barriers found in many crawl spaces can act as radon-rich reservoirs capable of contaminating a crawl space and house during periods of depressurization. With the exhaust components of the mitigation system in place, radon levels below the plastic decreased by more than 95% under both passive and active suction conditions. Based on the study, the design of a cost-effective subplastic suction passive radon mitigation system for crawl spaces seems promising

    In this report, it is studied where and under what conditions houses can be built in the neighbourhood of nuclear power plants. Building norms and location distances are investigated. First, the Dutch and foreign norms with respect to population densities are listed. Only industrial, densely populated neighbour countries are considered. Next, it is calculated what consequences for housing a nuclear station may have within a radius of 20 km. Using these calculations it is studied whether the existing Dutch requirements are satisfied. Because it is expected that the norms are likely to be tightened up under the pressure of the nuclear controversy, the existing Dutch situation is also compared with the tighter foreign norms. Finally, the results of the study are summarized and some conclusions are drawn. (Auth.)

  16. Demolish or refurbish – Environmental benefits of housing conservation

    Directory of Open Access Journals (Sweden)

    Grace Ding

    2013-06-01

    Full Text Available Climate change and energy efficiency are some of the most pressing issues facing China today. With its economic growth since 1978, the government has struggled to contain environmental damages and social unrest related to the economy’s rapid transformation. With the rapid growth in population and urbanization the demand for housing has escalated and traditional housing has been under threat of demolition to make way for new construction. Traditional housing is generally considered wasteful in its use of land and/or energy, and is often demolished for more intensive and more energy-efficient housing, despite the resulting loss of embodied energy and urban amenity. A research project was undertaken to study the environmental performance of traditional housing in Hangzhou. The project looks into analyzing and comparing embodied energy and CO2 for seven dwellings. In addition indoor climate data were recorded and collected in the form of hourly temperature and humidity readings for one year in six local houses and in a modern unit as a control for one year. The research results reveal that there is little difference in environmental performance between traditional and conventional modern construction and the value of conservation rather than demolition as a strategic development for the construction industry.

    2009-07-01

    In Austria, the first passive house was built in 1996. Since then the market for passive houses has rapidly increased. Statistics show that there were more than 4000 residential units with about 10,000 passive house residents at the end of 2006 - more per capita than in any other country of the world. Sustainability requirements, however, have led to profound shifts in the need for collaboration between the actors involved in planning, constructing and using buildings. This paper draws on a qualitative case study to analyse the development and dissemination of passive houses in Austria by focussing on the role of intermediate organisations. Empirically, the paper is based on qualitative interviews with representatives of relevant organisations as well as the analysis of various documentary sources. The case study shows that new types of buildings, such as 'passive houses', have given rise to new actors and organisations to organise integrative planning processes, to set standards and market the passive house concept, to certify components, to transfer knowledge to professionals, to assist consumers in choosing architects, installers and technologies or to organise participation processes. New interest organisations mediate between producers and the policy level, energy agencies act as system builders to transfer these new technologies and practices into the mainstream building sectors, etc. Intermediation processes fulfilled by a broad range of organisations turned out to be of crucial importance for the coordination and shaping of the socio-technical system.

    1984-06-13

    Under the Department of Energy's Modular Industrial Solar Retrofit project, five industrial process heat systems incorporating line-focus solar collectors were designed and hardware was installed and tested at Sandia National Laboratories and the Solar Energy Research Institute. System designers and collector manufacturers participating in the project included Acurex Solar Corporation, BDM, Inc., Custom Engineering, Inc., Foster Wheeler Solar Development Corporation, Solar Kinetics, Inc., and Suntec Systems, Inc. This paper describes the testing of the qualification test systems which has been under way since mid-1982. Each qualification test system includes an equipment skid sufficient to support a collector field of 2300 m/sup 2/ aperture and one delta-tempeature string of from 175 to 460 m/sup 2/ aperture. Each system is capable of producing saturated steam at 1.7 MPa and operates at maximum outlet temperatures of from 250 to 290/sup 0/C. The test series includes function and safety tests to determine that the systems operate as specified, an unattended operation test of at least two weeks duration, performance tests to allow prediction of annual system performance, and life cycle tests to evaluate component lifetime and maintenance requirements. Since the start of testing, some twenty five modifications have been made to the various systems for the purpose of improving system performance and/or reliability, and appropriate tests of these modifictions have been made or are underway. This paper presents a description of the approach to testing of the MISR systems and selected test results.

    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.

    2015-01-01

    The increasing amount of data in industrial automation systems overburdens the user in process control and diagnosis tasks. One possibility to cope with these challenges consists of using smart assistance systems that automatically monitor and optimize processes. This article deals with aspects of data-driven assistance systems such as assistance functions, process models and data acquisition. The paper describes novel approaches for self-diagnosis and self-optimization, and shows how these assistance functions can be integrated in different industrial environments. The considered assistance functions are based on process models that are automatically learned from process data. Fault detection and isolation is based on the comparison of observations of the real system with predictions obtained by application of the process models. The process models are further employed for energy efficiency optimization of industrial processes. Experimental results are presented for fault detection and energy efficiency optimization of a drive system. (paper)

  7. 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

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

    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.

    In order to reduce the energy consumption of the building stock, a major trend is to drastically reduce the space-heating (SH) needs by improving the thermal performance of the envelope. In general, this measure is combined with efficient heating systems to minimize the delivered energy and greenhouse gas emissions. Nevertheless, these better systems are often more expensive so that the extra-investment could be hardly recovered for small-scale energy consumption. The main objective of the article is to show how equilibria between cost-effectiveness and environmental performance of heating systems are changed when small SH needs are considered (i.e. for passive and low-energy houses). The scope is limited to new single-family dwellings. Furthermore, the passive house standard provides means of simplifying the SH by using the ventilation air: the idea is that savings should counterbalance the extra-investment in super-insulation. In theory, a new global economic optimum is generated at the passive house level. The second objective of the work is to study which conditions could lead to this new optimum. Only a detached-house typology is investigated to address this last issue. Regarding methodology, all the investigations are done considering the Belgian context. Energy and environmental performance is evaluated using a method that complies with the EN-15603 and EN-15316 standards. - Highlights: ► Cost-benefit analysis is performed without incentives and is based on the Belgian market. ► Equilibria between cost-effectiveness and environmental performance of heating systems are changed for very low-energy houses. ► The space-heating simplification at the passive house level can hardly produce a new global economic optimum.

    Industrial single photon emission computed tomography (SPECT) is a promising diagnosis technique to investigate the dynamic behavior of process media. In the present study, a 12-gonal industrial SPECT system was developed using diverging collimators, and its performance was compared with those of hexagonal and 24-gonal systems. Of all of the systems, the 12-gonal type showed the best performance, providing (1) a detection-efficiency map without edge artifacts, (2) the best image resolution, and (3) reconstruction images that correctly furnish multi-source information. Based on the performance of the three different types of configurations, a SPECT system with 12-gonal type configuration was found most suitable for investigating and visualization of flow dynamics in industrial process systems. - highlights: • Industrial SPECT provides the dynamic behavior of multiphase industrial processes. • The present study compared performance of various industrial SPECT systems. • The 12-gonal SPECT system with diverging-collimator provides the best performance

  13. Adoption of innovative energy systems in social housing: Lessons from eight large-scale renovation projects in The Netherlands

    2012-01-01

    Thanks to new insights on the impacts that dwellings have throughout their life cycles, there has been increased attention to retrofitting innovative energy systems (IES) in existing housing. This paper uses an explorative case study design to gain more knowledge about the governance aspects of this under-researched topic. The central research question is: Which factors influence the adoption of innovative energy systems in social housing sites during renovation projects? To answer this question, eight large-scale renovation projects in The Netherlands were investigated. These case studies allowed the identification of barriers, enabling factors and perspectives from three main actors—housing associations, tenants and local authorities. It turns out that adopting IES encounters many barriers: lack of trust between project partners, delay in project progress, financial feasibility considerations, lack of support from tenants, lengthy legal permit procedures, over-ambitious project goals, poor experiences in previous projects, and IES ambitions that are not taken serious by key decision-makers. Furthermore, IES were only successfully fitted in three of the eight projects. Moreover, ambitions were lowered as the projects progressed in all the cases investigated. The study calls for further systematic, in-depth comparison of fitting IES in large-scale renovation projects in social housing. - Highlights: ► Attention to adoption of innovative energy systems in social housing. ► Several non-technical factors influence adoption. ► In-depth analysis of eight local-level renovation projects. ► Ambitions are lowered as projects progress. ► Barriers: financial feasibility, over-ambitious goals, delay, lack of trust.

    The paper presents a new electron beam application in the pharmaceutical industry: an in-line self-shielded atropic transfer system using electron beam for surface decontamination of products entering a pharmaceutical filling line. The unit was developed by Linac Technologies in response to the specifications of a multi-national pharmaceutical company, to solve the risk of microbial contamination entering a filling line housed inside an isolator. In order to fit the sterilization unit inside the pharmaceutical plant, a 'miniature' low-energy (200 keV) electron beam accelerator and e-beam tunnel were designed, all conforming to the pharmaceutical good manufacturing practice (GMP) regulations. Process validation using biological indicators is described, with reference to the regulations governing the pharmaceutical industry. Other industrial applications of a small-sized self-shielded electron beam sterilization unit are mentioned

    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.

    2007-01-01

    Hybrid photovoltaic/thermal (PV/T) systems consist of PV modules and heat extraction units mounted together. These systems can simultaneously provide electrical and thermal energy, thus achieving a higher energy conversion rate of the absorbed solar radiation than plain photovoltaics. Industries show high demand of energy for both heat and electricity and the hybrid PV/T systems could be used in order to meet this requirement. In this paper the application aspects in the industry of PV/T systems with water heat extraction is presented. The systems are analyzed with TRNSYS program for three locations Nicosia, Athens and Madison that are located at different latitudes. The system comprises 300 m 2 of hybrid PV/T collectors producing both electricity and thermal energy and a 10 m 3 water storage tank. The work includes the study of an industrial process heat system operated at two load supply temperatures of 60 deg. C and 80 deg. C. The results show that the electrical production of the system, employing polycrystalline solar cells, is more than the amorphous ones but the solar thermal contribution is slightly lower. A non-hybrid PV system produces about 25% more electrical energy but the present system covers also, depending on the location, a large percentage of the thermal energy requirement of the industry considered. The economic viability of the systems is proven, as positive life cycle savings are obtained in the case of hybrid systems and the savings are increased for higher load temperature applications. Additionally, although amorphous silicon panels are much less efficient than the polycrystalline ones, better economic figures are obtained due to their lower initial cost, i.e., they have better cost/benefit ratio

    This report presents the design and evaluation of an innovative wall system. This highly insulated (high-R) light-frame wall system for use above grade in residential buildings is referred to as Extended Plate & Beam (EP&B). The EP&B design is the first of its kind to be featured in a new construction test house (NCTH) for the DOE Building America program. The EP&B wall design integrates standard building methods and common building products to construct a high-R wall that minimizes transition risks and costs to builders. The EP&B design combines optimized framing with integrated rigid foam sheathing to increase the wall system's R-value and reduce thermal bridging. The foam sheathing is installed between the wall studs and structural wood sheathing. The exterior wood sheathing is attached directly to a framing extension formed by extended top and bottom plates. The exterior wood sheathing can dry to the exterior and provides bracing, a clear drainage plane and flashing surface for window and door openings, and a nailing surface for siding attachment. With support of the DOE Building America program, Home Innovation Research Labs partnered with Lancaster County Career and Technology Center (LCCTC) to build a NCTH in Lancaster, PA to demonstrate the EP&B wall design in a cold climate (IECC climate zone 5A). The results of the study confirmed the benefits of the systems and the viability of its integration into the house construction process.

    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

    Verification of critical software is a high priority but a challenging task for industrial control systems. For many kinds of problems, testing is not an efficient method. Formal methods, such as model checking appears to be an appropriate complementary method. However, it is not common to use model checking in industry yet, as this method needs typically formal methods expertise and huge computing power. In the EN-ICE-PLC section, we are working on a [methodology][1] and a tool ([PLCverif][2]) to overcome these challenges and to integrate formal verification in the development process of our PLC-based control systems.

    A unique clade of the bacterium Mycoplasma gallisepticum (MG), which causes chronic respiratory disease in poultry, has resulted in annual epidemics of conjunctivitis in North American house finches since the 1990s. Currently, few immunological tools have been validated for this songbird species. Interleukin-1β (IL-1β) is a prototypic multifunctional cytokine and can affect almost every cell type during Mycoplasma infection. The overall goal of this study was to develop and validate a direct ELISA assay for house finch IL-1β (HfIL-1β) using a cross-reactive chicken antibody. A direct ELISA approach was used to develop this system using two different coating methods, carbonate and dehydration. In both methods, antigens (recombinant HfIL-1b or house finch plasma) were serially diluted in carbonate-bicarbonate coating buffer and either incubated at 4 °C overnight or at 60 °C on a heating block for 2 hr. To generate the standard curve, rHfIL-1b protein was serially diluted at 0, 3, 6, 9, 12, 15, 18, 21, and 24 ng/mL. Following blocking and washing, anti-chicken IL-1b polyclonal antibody was added, plates were later incubated with detecting antibodies, and reactions developed with tetramethylbenzidine solution. A commercially available anti-chicken IL-1β (ChIL-1β) polyclonal antibody (pAb) cross-reacted with house finch plasma IL-1β as well as bacterially expressed recombinant house finch IL-1β (rHfIL-1β) in immunoblotting assays. In a direct ELISA system, rHfIL-1β could not be detected by an anti-ChIL-1β pAb when the antigen was coated with carbonate-bicarbonate buffer at 4°C overnight. However, rHfIL-1β was detected by the anti-ChIL-1β pAb when the antigen was coated using a dehydration method by heat (60°C). Using the developed direct ELISA for HfIL-1β with commercial anti-ChIL-1β pAb, we were able to measure plasma IL-1β levels from house finches. Based on high amino acid sequence homology, we hypothesized and demonstrated cross-reactivity of

    materials adapted from the boating industry, were developed by the student team to render the SURE House’s building envelope flood proof up to the FEMA AE 6/7 Zone (+ 6/7 feet of water above sea-level). Designed and fabricated utilizing glass-fiber composite materials, the custom storm shutter system serves to protect the large glazed openings of the home from both air-borne debris impact and water infiltration during a storm event while also providing deterrence from the vandalism that often occurs in the aftermath of a calamitous event. During extended power outages, a ‘resilient’ solar array is capable of supplying critical amounts of energy and hot water to the home, without the use of battery storage or grid infrastructure. PV Description AC GRID-TIED PV SYSTEM The SURE HOUSE solar system consists of two distinct arrays, the grid-tied rooftop array which produces AC Powerand the shutter-mounted array which converts DC power generated by the modules directly into usable heat for the domestic hot water (DHW). The roof-mounted AC grid-tied array is comprised of three strings, two 11 module strings connected to an SMA SB 5000TL-US-223 inverter and a single 10 module string equipped and an SMA SB 3000TL-US-22 central inverter. All modules for the rooftop AC array are LG MonoX 2804 watt solar panels, chosen for their durability and efficiency. Inverter sizing and string size are optimized to the electrical characteristics of the chosen PV modules and the desired energy production, see Appendix 5B. The SURE HOUSE is projected to produce 12,353 kWh per year to meet 6,157 kWh per year of estimated consumption. Solar modules for the two AC grid-tied sub arrays are mounted on the main roof surface of the SURE HOUSE with a 10 degree tilt angle using a partially-ballasted polyethylene roof mounting system made by Renusol, which is particularly suited to the corrosive salt air of a coastal environment. This method was chosen for its installation simplicity and to limit

    The report gives results of follow-up tests in 38 difficult-to-mitigate Pennsylvania houses where indoor radon reduction systems had been installed 2 to 4 years earlier. Objectives were to assess system durability, methods for improving performance, and methods for reducing installation and operating costs. The durability tests indicated that the 38 systems have not experienced any significant degradation in indoor radon levels or in system flows/suctions, except in 6 houses where system fans failed, and in houses where homeowners turned off the systems. Tests to improve performance indicated that nearly all of the elevated residual radon levels are due to re-entrainment back into the house of very-high-radon exhaust gas from the soil depressurization systems, and to radon release from well water. Tests to reduce system costs showed that premitigation sub-slab suction field measurements can help prevent installation of too many suction pipes when communication is good, but suggest a need for too many pipes when communication is poor. Soil depressurization fans could not be turned down to the extent expected in some systems that were over-designed. Between 6 and 42% of the exhausted air was withdrawn from the house

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

    2014-12-01

    Full Text Available This article explores major trends and patterns of change embedded in the overall process of economic, social and political transformation reshaping the urban challenges in eastern European cities. It reflects on important drivers of change such as efforts to create a market-based housing system and competitive housing markets in the post-communist urban world. The research draws much-needed attention to an important set of urban and housing policy issues with broad implications for understanding the transition process in the region. It explores the multi-layered processes of market-based housing reforms (privatisation, deregulation and devolution and their impact on the spatial transformation of urban housing markets in eastern European cities. The main argument, supported with empirical evidence from a number of eastern European cities, is that the impact of these most significant processes of urban change has created a mosaic of diverse urban challenges. Exploring these urban challenges through the housing lens sets the stage for a better understanding of urban social movements in eastern European cities and their dynamic realities. The article argues that the diverse role of urban social movements can be explained by reference to democratic traditions, practices and policy cultures in eastern European cities, and also to institutional structures and the capacity of non-market stakeholders. In some cases, stronger government and governance traditions since the political changes of the 1990s would allow non-government organisations to “voice” their concerns and be accepted as a legitimate partner in coalitions responding to urban challenges. In other cases, such capacity and institutional collaboration may be non-existent, leading to “exit” and abandonment of formal systems. In the first option, urban social movements have resurrected debates about gentrification and social segregation in housing estates and neighbourhoods previously

    For the past few years, a hybrid generation system including solar panel and gas cogeneration is being used for residential houses. Solar panels can generate electronic power at daytime; meanwhile, it cannot generate electronic power at night time. But the power consumption of residential houses usually peaks in the evening. The gas engine cogeneration system can generate electronic power without such a restriction, and it also can generate heat power to warm up house or to produce hot water. In this paper, we propose the solar panel and gas engine co-generation hybrid system with an energy storage device that is combined by dc bus. If a black out occurs, the system still can supply electronic power for special house loads. We propose the control scheme for the system which are related with the charging level of the energy storage device, the voltage of the utility grid which can be applied both grid connected and stand alone operation. Finally, we carried out some experiments to demonstrate the system operation and calculation for loss estimation.

    1988-01-01

    It is generally acknowledged that radon mitigation can only be accomplished on a national scale through a cooperative effort of government, industry and an informed public. The Environmental Protection Agency has developed, demonstrated and published acceptable procedures for testing and preventing the entry or radon into occupancies, as well as procedures for removal when it is not possible or economically viable to prevent radon from entering these occupancies. Various states have instituted programs for industry implementation of EPA procedures and public education programs are now underway. Industry effort will be required to mitigate existing housing stock, to insure new radon resistant housing and, equally important, to provide for radon monitoring and servicing of mitigation measures for centuries to come. What the nature of that industry can and should be and how government agencies can encourage the development of such industry is the subject of this paper

    With the help of a case study, the article has explored current practices of implementation of governmental affordable housing programme for urban poor in a slum of India. This work shows that the issues associated with the problems of governmental affordable housing programme has to be addressed to with a suitable methodology as complexities are not only dealing with quantitative data but qualitative data also. The Hard System Methodologies (HSM), which is conventionally applied to address the issues, deals with real and known problems which can be directly solved. Since most of the issues of affordable housing programme as found in the case study are subjective and complex in nature, Soft System Methodology (SSM) has been tried for better representation from subjective points of views. The article explored drawing of Rich Picture as an SSM approach for better understanding and analysing complex issues and constraints of affordable housing programme so that further exploration of the issues is possible.

    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.

    Vibration and noise caused by gear dynamics at the meshing teeth propagate through power transmission components to the surrounding environment. This study is devoted to developing computational tools to investigate the vibro-acoustic propagation of gear dynamics through a gearbox using different bearings. Detailed finite element/contact mechanics and boundary element models of the gear/bearing/housing system are established to compute the system vibration and noise propagation. Both vibration and acoustic models are validated by experiments including the vibration modal testing and sound field measurements. The effectiveness of each bearing type to disrupt vibration propagation is speed-dependent. Housing plays an important role in noise radiation .It, however, has limited effects on gear dynamics. Bearings are critical components in drivetrains. Accurate modeling of rolling element bearings is essential to assess vibration and noise of drivetrain systems. This study also seeks to fully describe the vibro-acoustic propagation of gear dynamics through a power-transmission system using rolling element and fluid film wave bearings. Fluid film wave bearings, which have higher damping than rolling element bearings, could offer an energy dissipation mechanism that reduces the gearbox noise. The effectiveness of each bearing type to disrupt vibration propagation in explored using multi-body computational models. These models include gears, shafts, rolling element and fluid film wave bearings, and the housing. Radiated noise is mapped from the gearbox surface to surrounding environment. The effectiveness of rolling element and fluid film wave bearings in breaking the vibro-acoustic propagation path from the gear to the housing is investigated.

    Massive fossil fuel burning caused by industrialization development is one major reason of global climate change. After Copenhagen climate summit, the studies of low-carbon city gain attentions from many countries. On 25th Nov. 2009, the State Council executive meeting announced that by 2020 China will reduce the carbon dioxide emissions per unit of GDP by 40% to 45% compared with the level of 2005. Industrial Park as an important part of city, has developed rapidly in recent years, and turns into a key element and an alternative mechanism to achieve emission reduction target. Thus, establishing a low carbon development model for industrial park is one of the most effective ways to build sustainable low carbon cities. By adopting the self-evaluation system of low carbon industrial park, this research aims to summarize the low carbon concept in industrial park practice. According to The Guide for Low Carbon Industrial Development Zones, the quantitative evaluation system is divided into 4 separate categories with 23 different quantitative indicators. The 4 categories include: 1) energy and GHG management (weigh 60%), 2) circular economy and environmental protection (weigh 15%), 3) administration and incentive mechanisms of industrial parks (weigh 15%), and 4) planning and urban forms (weigh 10%). By going through the necessary stages and by leading continuous improvements low carbon development goals can be achieved. Tianjin TEDA industrial park is selected as one case study to conduct an assessment on TEDA low-carbon development condition. Tianjin TEDA Industrial Park is already an ecological demonstration industrial park in China, with good foundations on environmental protection, resource recycling, etc. Based on the self-evaluation system, the indicators, such as the energy using efficiency and the degree of land intensive utilization, are also analyzed and assessed. Through field survey and data collection, in accordance with the quantitative self

    Tarvainen, V.; Froeblom, J.

    1983-03-01

    Energy consumption in the mechanical forest industry in 1979 was studied by sending questionnairies to all the significant factories Information was requested on power and heat consumption and installed power in separate process phases. For background information, some aspects of the production process were also requested. The factories which answered the inquiry produced about one half of the doors and windows manufactured in 1979, one sixth of the finger jointed timber and about one third of other products in the branch. The total energy consumption in the branch was 1 556 TJ, 77% was heat. The share of the joinery industry (doors, windows and fixtures) in the total was 2/3, of which 86% was heat energy. The energy needed in the wooden house industry was 219 TJ, in planing works 137 TJ, in the gluelam industry 86 TJ, in finger jointing 76 TJ and in the production of roof trusses about 6 TJ. The investigated brances accounted for 7% of the energy consumption of the whole mechanical forest industry. The energy consumption in producing products of the same type in different factories varied very much. The differences were partially structural. However, there is considerable room for energy savings in many of the factories.

    Full Text Available Nowadays in Russian cities a significant part of the housing stock in areas of existing buildings has a high level of physical and moral deterioration, indicators of infrastructure elements do not meet the current and future requirements. Reconstruction of residential buildings is one of the important directions in solving the housing problem. This will allow us to not only extend the life cycle but also significantly improve the quality of housing, eliminate a communal settlement, provide the houses with modern engineering equipment, improve architectural expressiveness of buildings and increase their energy efficiency. For buildings of different construction periods an individual approach is required in the development of methods and technologies of reconstruction. At the same time, the process should take place not in a separate building but in a group of buildings, neighborhood or district. This makes it possible to undertake a comprehensive assessment of the urban development situation and make the most rational decisions to meet modern conditions, and provide logical connection between various architectural trends. At the same time, there are possibilities for compaction and decompaction of buildings, the rational use of inter-district, underground space and communication systems. Moscow region is a large region, which occupies an area of 46 thousand square kilometers. The region includes more than 38 municipalities (municipal districts, urban and rural settlements. The region’s population is more than 7 million people. Moscow oblast has a central location in the Russian Federation and a close relationship with the capital. This relationship with Moscow is manifested through common social, scientific, industrial, transport links, environmental protection problems, labor resources.

    The Constellation Program cancellation reversed the government and commercial space industry's roles and relationships by dedicating the majority of the federal funding and opportunities to the commercial space industry and left the government space industry in search of an approach to collaborate with the dominant organization, the commercial space industry service providers. The space industry government agencies, Air Force Space Command (AFSPC) and National Aeronautics and Space Administration (NASA) had realized that to gain resources in the new commercially oriented economic environment, they had to work together and possess the capabilities aligned with the National Space Policy's documented goals. Multi-organizational collaboration in space industry programs is challenging, as NASA, AFSPC, and commercial providers, follow different [1] enterprise architecture guidance such as the NASA systems engineering Handbook, MIL-STD-499 and "A Guide to the systems engineering Body of Knowledge" by the International Council on systems engineering [2] [3]. A solution to streamline their enterprise architecture documentation and meet National Space Policy goals is the Multi-User Architecture Maturity Model Methodology (MAM3), which offers a tailored systems engineering technique the government agencies and private companies can implement for the program's maturity level. In order to demonstrate the MAM3, a CubeSat motivated study was conducted partnering a commercial provider with a government agency. A survey of the commercial space industry service providers' capabilities was performed to select the private companies for the study. Using the survey results, the commercial space industry service providers were ranked using the Analytic Hierarchy Process (AHP) [4]. The AHP is a structured technique for making complex decisions for representing and quantifying its weights, relating those weights to overall goals, and evaluating alternative solutions [5] - [8].

    2015-01-01

    This study provides a techno-economic evaluation of retrofitting internal combustion engine (ICE) based cogeneration systems in the Canadian housing stock (CHS). The study was conducted using the Canadian Hybrid Residential End-Use Energy and GHG Emissions Model (CHREM). CHREM includes close to 17,000 unique house files that are statistically representative of the Canadian housing stock. The cogeneration system performance was evaluated using a high resolution integrated building performance simulation software. It is assumed that the ICE cogeneration system is retrofitted into all houses that currently use a central space heating system and have a suitable basement or crawl space. The GHG emission intensity factor associated with marginal electricity generation in each province is used to estimate the annual GHG emissions reduction due to the cogeneration system retrofit. The results show that cogeneration retrofit yields 13% energy savings in the CHS. While the annual GHG emissions would increase in some provinces due to cogeneration retrofits, the total GHG emissions of the CHS would be reduced by 35%. The economic analysis indicates that ICE cogeneration system retrofits may provide an economically feasible opportunity to approach net/nearly zero energy status for existing Canadian houses. - Highlights: • Techno-economic evaluation ICE cogeneration systems for Canadian housing is reported. • ICE cogeneration retrofit could yield 13% annual energy savings in Canadian housing. • Annual GHG emissions of Canadian housing could decrease by 35% with ICE cogeneration. • But, in some provinces, GHG emissions would increase as a result of ICE cogeneration

    The CERN Unified Industrial Control Systems framework (UNICOS) is a software generation methodology and a collection of development tools that standardizes the design of industrial control applications [1]. A Software Factory, named the UNICOS Application Builder (UAB) [2], was introduced to ease extensibility and maintenance of the framework, introducing a stable metamodel, a set of platformindependent models and platformspecific configurations against which code generation plugins and configuration generation plugins can be written. Such plugins currently target PLC programming environments (Schneider and SIEMENS PLCs) as well as SIEMENS WinCC Open Architecture SCADA (previously known as ETM PVSS) but are being expanded to cover more and more aspects of process control systems. We present what constitutes the UNICOS metamodel and the models in use, how these models can be used to capture knowledge about industrial control systems and how this knowledge can be leveraged to generate both code and configuratio...

    Energy saving and emission reduction have become targets for modern society due to the potential energy crisis and the threat of climate change. A distributed hybrid renewable energy system (HRES) consists of photovoltaic (PV) arrays, a wood-syngas combined heat and power generator (CHP) and back-up batteries is designed to power a typical semi-detached rural house in China which aims to meet the energy demand of a house and to reduce greenhouse gas emissions from the use of fossil fuels. Based on the annual load information of the house and the local meteorological data including solar radiation, air temperature, etc., a system model is set up using HOMER software and is used to simulate all practical configurations to carry out technical and economic evaluations. The performance of the whole HRES system and each component under different configurations are evaluated. The optimized configuration of the system is found

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

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

    In this report the placement of the circulation-pump in of waterborne radiator systems, as well as their filling and deairation are investigated. The study was done by literature studies and interviews with consultants and companies active on the HVAC-market. It was concluded that different placements of the pump in relationship to the heat exchanger exist, and the arguments for the choice of placement are varying. The main explanation of the choice of placement is that it is based on experience/or by practical reasons. The most important factor influencing the placement of the pump found, was how the pump is situated in relation to the expansion-tank. To maintain pressure in the whole system the expansion-tank should be placed on the suction side of the pump without any intermediate pressure-dropping devices in between. This placement ensures overpressure in the whole radiator-system and reduces the risk of unwanted leak in of air. To avoid cavitation sufficient static pressure on the suction side of the pump is necessary. The pressure increases with the temperature, which must be taken into consideration if the pump is placed on the warm side of the heat-exchanger. From this point of view a placement in the return-pipe from the radiator-system is to be preferred. Before advices for HVAC-branch regarding placement of the circulation-pump in the heating systems can be implemented, it is of big importance to analyse and clearly specify the advantages and disadvantages of a certain placement of the pump. There is a need of directions to get house-internal systems to operate properly together with district heating system. This is especially important when older heating systems with burners and shunt valves are being connected. Filling and deairation of the radiator system is of great importance for the function of the system. A radiator-system with significant level of air remains is difficult to adjust and will not work properly. Air in the radiators leads to

    2011-12-01

    Full Text Available Complexity in industrial organizations became more difficult and complex to be solved and it needs more attention from academicians and technicians. For these reasons, complexity in industrial organizations represents a new challenge in the next decades. Until now, analysis of industrial organizations complexity is still remaining a research topic of immense international interest and they require reduction in their complexity. In this paper, analysis of complexity in industrial organizations is shown based on the perspective of systems engineering analyst. In this perspective, analysis of complexity was divided into different levels and these levels were defined as complexity levels. A framework of analyzing these levels was proposed and suggested based on the complexity in industrial organizations. This analysis was divided into four main issues: industrial system vision, industrial system structure, industrial system operating, and industrial system evaluating. This analysis shows that the complexity of industrial organizations is still an ill-structured and a multi-dimensional problem.

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

    Housing industry in Malaysia is growing rapidly due to the increase in population and the arising of economic level of Malaysian people. Most residential houses are built according to the standard residential design that may lead to house renovation by the buyers after purchasing the house. A method of using Unmanned Aerial Vehicle (UAV) monitoring was used to obtain information of the renovated houses directly on-site at Taman Manis 2, Parit Raja, Batu Pahat. Through comparison of image captured by the UAV with the original house plans, we found out that a total of 160 units out of 336 units of houses undergo a renovation process. Surprisingly, 41 units have been renovated illegally which has 40% to 96% of renovation rate. The acquired data were analyzed and can be concluded that the method of using UAVs to obtain information is highly recommended. The study is expected to help Municipal Council to detect improper & illegal renovation by the residents in a residential area.

    Whole-house mechanical ventilation is a critical component to a comprehensive strategy for good indoor air quality (IAQ). However, due to lack of integration with standard heating and cooling systems, and perceptions from a portion of the homebuilding industry about risks related to increased energy use, increased cost, and decreased comfort, voluntary and code-required adoption varies amongst regions. Smart ventilation controls (SVC) balance energy consumption, comfort, and IAQ by optimizing mechanical ventilation operation to reduce the heating and/or cooling loads, improve management of indoor moisture, and maintain IAQ equivalence according to ASHRAE 62.2.

    2011-09-01

    This paper reports the result of a CFD (Computational Fluid Dynamics) study on the Submerged Rotary Jet (SRJ) mixing system in a large industrial crude oil storage tank (one million barrels). This system has been installed on the tank just for reduction of sludge, but improper installation causes more accumulation of sludge on one side of tank. The main question is: How can we improve the mixing operation in this tank? For the purpose, a three dimensional modeling is carried out using an in-house CFD code and RNG k-ɛ model for turbulence prediction. The results show that pump suction location and crude oil velocity in tank are most effective factors on the sludge amount. Then, different ways such as increasing of jet flow rate, increasing and decreasing of tank height and reducing of nozzle diameter have been investigated. Finally, in this case, the results show the sedimentation of sludge in whole tank can be removed by 20% increasing of jet flow rate.

    A new regulation regarding agricultural operations in Quebec was passed in June 2002. It stated the new standards for managing phosphorous generated from animal livestock. The regulation is intended to protect the environment, more specifically, water, soil and air quality. This new regulation stipulates that agricultural producers acquire a balanced phosphorous assessment by 2010. In order to achieve this, a system is needed to separate solid and liquid pig manure on a daily basis. Producers must also comply with environmental requirements on odour elimination and atmospheric control. The proposed solid-liquid separation system would improve the indoor and outdoor air quality at pig housing facilities by reducing toxic gas and bioaerosol formation. In addition, it would contribute to stream purification. The solid-liquid separation technique was successfully tested in a pilot project at a mini pig housing facility. It was concluded that type of separation equipment system could readily used for other types of animal farming, such as cattle raising. 41 refs., 13 tabs., 12 figs

    The CERN Unified Industrial Control Systems framework (UNICOS) is a software generation methodology and a collection of development tools that standardizes the design of industrial control applications. A Software Factory, named the UNICOS Application Builder (UAB), was introduced to ease extensibility and maintenance of the framework, introducing a stable meta-model, a set of platform-independent models and platform-specific configurations against which code generation plug-ins and configuration generation plug-ins can be written. Such plug-ins currently target PLC programming environments (Schneider and SIEMENS PLCs) as well as SIEMENS WinCC Open Architecture SCADA (previously known as ETM PVSS) but are being expanded to cover more and more aspects of process control systems. We present what constitutes the UNICOS meta-model and the models in use, how these models can be used to capture knowledge about industrial control systems and how this knowledge can be used to generate both code and configuration for a variety of target usages.

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

    This paper examines the impact of local (county-level) house prices on individual self-reported mental health using individual level data from the United States Behavioral Risk Factor Surveillance System between 2005 and 2011. Exploiting a fixed-effects model that relies on within-county variations, relative to the corresponding changes in other counties, I find that while individuals are likely to experience worse self-reported mental health when local house prices decline, this association is most pronounced for individuals who are least likely to be homeowners. This finding is not consistent with a prediction from a pure wealth mechanism but rather with the hypothesis that house prices act as an economic barometer. I also demonstrate that the association between self-reported mental health and local house prices is not driven by unemployment or foreclosure. The primary result-that lower local house prices have adverse impact on self-reported mental health of homeowners and renters-is consistent with studies using data from the United Kingdom.

    Full Text Available The presented research work proposes a study about the ≪flexibility≫ requirement, aiming to define its role in social housing requalification. For the Preturo A.T.E.R. settlement, characterized by considerable lack of technological units and performance gaps, we propose systems adaptable as for the variability of the dwelling, working and socialization needs for settled or to be settled users. The originality of the work consists in the identification of the flexibility as sustainable functional requalification strategy, also aware that the post-industrial buildings predisposition to transformation, given by their deterioration conditions, and the performance fitting possibilities are directly proportional.

    The aim of this study was to compare egg production performance and welfare traits of laying hens kept in conventional cage (CC), enriched cage (EC), and free range (FR). Lohmann Brown laying hens (n = 480 with 160 per housing type) were studied across a production cycle from placement at 17 wk until depopulation at 66 wk. The hens were randomly allocated into cages or pens of housing system groups; within each system there were four replicates with 40 hens in each pen or cage. The hen day egg production (P = 0.037), feed intake (FI) (P 0.05). The hens in the FR system had additional space for optimum comfort and better feather and bone traits, but the dirty egg ratio, feed consumption, and foot lesions were higher than in CC and EC systems. © 2016 Poultry Science Association Inc.

    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.

    Nihoh Keizai Shimbun started supplying "Industry/Technology Information Service" from July 1989 as a part of Nikkei Telecom Package, which is online information service using personal computers for its terminals. Previously Nikkei's database service mainly covered such areas as economy, corporations and markets. On the other hand, the new "Industry/Technology Information Service" (main data covers industry by industry information-semi macro) is attracting a good deal of attention as it is the first to supply science and technology related database which has not been touched before. Moreover it is attracting attention technically as it has an access by gateway system to JOIS which is the first class science technology file in Japan. This report introduces data and system of "Industry/Technology Information Service" briefly.

  1. Rethinking Affordable Housing Delivery: An Analytical Insight

    Full Text Available Malaysia currently has a housing shortage of 12 million units. Towards the year 2020, this would require an annual supply of a minimum of 2 million homes. With the current production rate, the deficits will remain over the next 100 years. The crisis will lead to poor standards of living, un-affordable rental price, high mortgage payment, abandonment, and dilapidation of the existing housing stock. Lack of affordable housing is already a source of concern among many Malaysians. The middle and lower income earners spend more than 30% of their income on rent or for mortgage payment. Housing rent or mortgage is a basic need like foods, education, clothing and health. The government has introduced various measures to address the housing deficit. Despite these measures, the housing supply and distribution gaps continue to grow. To better understand the issues, there is a need to examine how the procurement planning in the affordable housing delivery supply chain and market is formulated, explore how cost of affordable housing would be reduced, identify the user value systems in affordable housing, and identify the criteria in the current regulatory framework? For these purposes, this paper reviews the relevant literature to reach preliminary findings on the stated issues. Among the factors found accounting for housing shortages, the overwhelming factors were that of poor policies, strategies, practice, management, and finance. The findings are meaningful in framing an affordable housing delivery model. It could also be useful to stakeholders involved in affordable housing delivery in Malaysia and elsewhere.

    This article deals with computer systems in nuclear industry. In most nuclear facilities it is necessary to handle a great deal of data and of actions in order to help plant operator to drive, to control physical processes and to assure the safety. The designing of reactors requires reliable computer codes able to simulate neutronic or mechanical or thermo-hydraulic behaviours. Calculations and simulations play an important role in safety analysis. In each of these domains, computer systems have progressively appeared as efficient tools to challenge and master complexity.

    A number of mutilating procedures, such as dehorning in cattle and goats and beak trimming in laying hens, are common in farm animal husbandry systems in an attempt to prevent or solve problems, such as injuries from horns or feather pecking. These procedures and other practices, such as early maternal separation, overcrowding, and barren housing conditions, raise concerns about animal welfare. Efforts to ensure or improve animal welfare involve adapting the animal to its environment, i.e., by selective breeding (e.g., by selecting "robust" animals) adapting the environment to the animal (e.g., by developing social housing systems in which aggressive encounters are reduced to a minimum), or both. We propose adapting the environment to the animals by improving management practices and housing conditions, and by abandoning mutilating procedures. This approach requires the active involvement of all stakeholders: veterinarians and animal scientists, the industrial farming sector, the food processing and supply chain, and consumers of animal-derived products. Although scientific evidence about the welfare effects of current practices in farming such as mutilating procedures, management practices, and housing conditions is steadily growing, the gain in knowledge needs a boost through more scientific research. Considering the huge number of animals whose welfare is affected, all possible effort must be made to improve their welfare as quickly as possible in order to ban welfare-compromising procedures and practices as soon as possible.

  10. Mass Balance Applied to Brazilian Conventional Broiler Houses during One Production Cycle

    Directory of Open Access Journals (Sweden)

    A Migliavacca

    Full Text Available ABSTRACT Brazil plays an important role in global poultry production as it is the world's largest chicken exporter and the third largest broiler producer. Despite the development achieved by the Brazilian broiler industry as a result of the integrated production system, many obstacles still need to be overcome, in particular, housing environment. In this regard, detailed knowledge of the inputs, outputs, and primary waste generated by broiler production cycles is essential to establish a baseline for energy balance research studies and to develop environmental solutions. This article proposes a mass balance of conventional broiler houses of southern Brazil sheds in order to predict their outputs, but that may also be applicable to other regions with similar climate. Control volumes considered the heating, cooling, and rearing processes. All generated products and wastes were estimated considering litter production and the total production per cycle. Despite the variety of the microclimates, the results were very close to those reported in experiments, indicating that this model is adequate for this kind of estimation.

    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.

    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.

    Some cooperative methods have been proposed and executed as the R&D (research and development) between universities and industries meld together to form a new hybeid business. This paper proposes the ides of “Fusion Education” for the advancement of education and for fostering new business. In fusion education, university students will begin by mainly verifying the application potential of a developed system such as modulated robotic software, for example, and improve specific areas when and if needed. Then, the university will rank the systems according to its reliability or safety record (based on the student) complete verification test which includes data on when the robot will be operated and under what varying conditions (such as performance in various private houses). The university essentially gives students the chance to find a solution to practical problems while the industry gets a reliable (fully authorized) system as result of this education process. The concept and feasibility of this “fusion education” will now be discussed.

  16. SIMS: The SLAC Industrial Measurement System

    1990-01-01

    Kern was the first survey company to market an Industrial Measurement System when it released ECDS (Electronic Coordinate Determination System) in the mid-1980s. Originally written for the PDP-11, a version was later released for the PC (ECDS-PC). SLAC purchased this system in 1986 and immediately began to use it for the alignment of the SLC (Stanford Linear Collider). Although ECDS enabled SLAC to perform tasks with a speed never before achieved, they experienced limitations in the software. Since Kern proved unresponsive and SLAC was unable to purchase the source code for any amount of money, they set about writing their own portions of code. They first wrote a system of menus tailored for their specific alignment tasks, and disabled much of the ECDS menu structure. Due to dissatisfaction with the ECDS bundle adjustment program, they wrote their own bundle adjustment in 1988. A further step towarad having their own complete IMS was to develop a data capture program, a task which has been underway since the beginning of this year. They do not yet have data analysis features that are fully integrated, but they do have stand-alone packages that have been written at SLAC. When they first started tinkering with ECDS there was no intention of developing a complete system, but they now have all the elements of such a system - SIMS, the SLAC Industrial Measurement System

    Traditionally, the primary focus of the chemical industry has been safety and productivity. However, recent threats to our nation’s critical infrastructure have prompted a tightening of security measures across many different industry sectors. Reducing vulnerabilities of control systems against physical and cyber attack is necessary to ensure the safety, security and effective functioning of these systems. The U.S. Department of Homeland Security has developed a strategy to secure these vulnerabilities. Crucial to this strategy is the Control Systems Security and Test Center (CSSTC) established to test and analyze control systems equipment. In addition, the CSSTC promotes a proactive, collaborative approach to increase industry's awareness of standards, products and processes that can enhance the security of control systems. This paper outlines measures that can be taken to enhance the cybersecurity of process control systems in the chemical sector.

  19. Air Quality in Alternative Housing Systems May Have an Impact on Laying Hen Welfare. Part I—Dust

    Directory of Open Access Journals (Sweden)

    Bruce David

    2015-07-01

    Full Text Available The new legislation for laying hens in the European Union put a ban on conventional cages. Production systems must now provide the hens with access to a nest, a perch, and material for dust bathing. These requirements will improve the behavioral aspects of animal welfare. However, when hens are kept with access to litter, it is a concern that polluted air may become an increased threat to health and therefore also a welfare problem. This article reviews the literature regarding the health and welfare effects birds experience when exposed to barn dust. Dust is composed of inorganic and organic compounds, from the birds themselves as well as from feed, litter, and building materials. Dust may be a vector for microorganisms and toxins. In general, studies indicate that housing systems where laying hens have access to litter as aviaries and floor systems consistently have higher concentrations of suspended dust than caged hens with little (furnished cages or no access to litter (conventional cages. The higher dust levels in aviaries and floor housing are also caused by increased bird activity in the non-cage systems. There are gaps in both the basic and applied knowledge of how birds react to dust and aerosol contaminants, i.e., what levels they find aversive and/or impair health. Nevertheless, high dust levels may compromise the health and welfare of both birds and their caretakers and the poor air quality often found in new poultry housing systems needs to be addressed. It is necessary to develop prophylactic measures and to refine the production systems in order to achieve the full welfare benefits of the cage ban.

  2. Industrial Energy Management Decision Making for Improved Energy Efficiency—Strategic System Perspectives and Situated Action in Combination

    Directory of Open Access Journals (Sweden)

    Patrik Thollander

    2015-06-01

    Full Text Available Improved industrial energy efficiency is a cornerstone in climate change mitigation. Research results suggest that there is still major untapped potential for improved industrial energy efficiency. The major model used to explain the discrepancy between optimal level of energy efficiency and the current level is the barrier model, e.g., different barriers to energy efficiency inhibit adoption of cost-effective measures. The measures outlined in research and policy action plans are almost exclusively technology-oriented, but great potential for energy efficiency improvements is also found in operational measures. Both technology and operational measures are combined in successful energy management practices. Most research in the field of energy management is grounded in engineering science, and theoretical models on how energy management in industry is carried out are scarce. One way to further develop and improve energy management, both theoretically as well as practically, is to explore how a socio-technical perspective can contribute to this understanding. In this article we will further elaborate this potential of cross-pollinating these fields. The aim of this paper is to relate energy management to two theoretical models, situated action and transaction analysis. We conclude that the current model for energy management systems, the input-output model, is insufficient for understanding in-house industrial energy management practices. By the incorporation of situated action and transaction analysis to the currently used input-output model, an enhanced understanding of the complexity of energy management is gained. It is not possible to find a single energy management solution suitable for any industrial company, but rather the idea is to find a reflexive model that can be adjusted from time to time. An idea for such a reflexive model would contain the structural elements from energy management models with consideration for decisions being

Along with the implementation of the National Housing Policy (2004, the National Housing System (2005, and the National Housing Plan (2008, a consistent model to face the Brazilian housing deficiency was created. The prime period of the actions and resources taken by the various government levels and private agents took place during the implementation of Minha Casa Minha Vida [My Home My Life] program (PMCMV, whose goal was to build a million houses. Based on the outlined context, this paper seeks to evaluate the relationship between National Housing Policy and PMCMV, discussing its implications on housing outlook in the country. A bibliographical and documentary research showed theoretical and conceptual unbalance between these two policies, allowing speculation on the prevalence of the economic component over the social one.

    Full Text Available The state, municipality, population and entrepreneurship interrelation mechanism is far from being perfect in Russian housing and communal services industry. The problem may be solved provided interests of all the above participants of the industry are balanced. Most reasonable is to provide for parallel functioning of the market and governmental and municipal bodies, all of them acting in accordance with respective legal norms. More power should be given to municipalities who are non-governmental local public self-management bodies formed to provide for proper living conditions topopulation within certain territory by asserting priority interests common for this population. Negative consequences of the monopoly status of suppliers and providers of communal services should be eradicated. Transition from the monopolistic and closed communal services market to that open and competitive should become general strategy of Russian housing and communal services industry development.

    Energy efficiency in industrial boiler steam systems can be very low due to old technologies, improper design and non-optimal operation of the steam systems. Solutions include efficiency assessments and investments in steam system optimizations, education and training for operators of the systems. This paper presents case studies on assessing and investing in boiler steam systems in China and Vietnam. Methodologies and approaches for data collection and analyses were designed specifically for each of the two countries. This paper concludes: (1) investing in energy efficiency in industrial boiler steam system in China and Vietnam are cost effective; (2) government should not sent national energy efficiency standards lower than that of energy companies or energy equipment manufactures. - Highlights: ► GEF successfully catalyzed investment in industrial energy efficiency boilers in China in 1990s. ► With about $100 million of investment by the GEF/World Bank/Chinese government, the project will mitigate 40 million tons of CO 2 by 2019. ► This generated lowest unit cost of carbon reduction in the world: about $2.5 per ton of CO 2 mitigation. ► Investing in energy efficiency in industrial boiler steam system today in Vietnam will be the same cost effective as in China: $2.1 per ton of CO 2 mitigation.

    Full Text Available A high prevalence of deviations and fractures of the keel bone is a widespread welfare problem in laying hens. The aim of this study was to experimentally investigate this multifactorial problem throughout the laying period and to compare the prevalence and severity in different layer lines and different housing systems. High performing white (WLA and brown (BLA pure bred layer lines and low performing white (R11, G11 and brown layer lines (L68 were kept in both single cages and a floor housing system. A total of 97 hens (19 or 20 from each line, respectively were repeatedly radiographed in the 35th, 51st and 72nd week of age. Fracture prevalence increased with age (p<0.001. The proportion of deviated keel bone area increased only for caged BLA, WLA and R11 hens (p<0.05 and was significantly higher for caged WLA and R11 hens compared to floor-housed WLA and R11 hens in the 72nd week of age (p<0.05. In the 72nd week of age hens in the floor housing system showed significantly more fractures than hens kept in cages (p<0.05. Prevalence of keel bone deviations was significantly higher in the white layer line R11 but significantly lower in the white layer line G11 compared to both brown layer lines and WLA (p<0.05. Brown layers showed significantly more fractures than white layers (p<0.05 in the 51st and 72nd week of age. Within the brown layers there was a significantly lower prevalence of deviations (p<0.05 and fractures (p<0.05 in the low performing (L68 compared to the high performing line (BLA. Our results show a different development of keel bone damage in caged compared to floor-housed hens under experimental conditions. Additionally, they indicate genetic effects on keel bone damage.

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

  2. LOGISTICS RISK RESEARCH OF PREFABRICATED HOUSE CONSTRUCTION ENGINEERING BASED ON CREDIBILITY METHOD

    Directory of Open Access Journals (Sweden)

    Xiaoping Bai

    2017-07-01

    Full Text Available In recent years, the prefabricated house industry has rapid development,.Because of fewer suppliers, higher demand transport scheme and complex quality test, the risks of construction engineering logistics links are relatively high. Studying how to effectively evaluate the risks of construction engineering logistics links is significant. According to the characteristics of the prefabricated house construction engineering, we analyse the construction engineering logistics risks and use the combined weights method to determine the weight of indexes which contains both subjective and objective factors, to improve the scientific value and the validity of the assessment. Based on credibility measure method, a new logistics risk evaluation model in prefabricated housing is established to estimate the risk during making prefabricated house construction engineering. The presented model can avoid the subjectivity of selecting the membership function and solve the problem of how to comprehensively assess the construction engineering logistics risk in a certain extent.

    2013-12-01

    Full Text Available Energy efficiency is essential in the efforts to achieve a 20% reduction of primary power consumption by 2020. It is widely recognized that the potential of energy saving in buildings is large. Considering the tendencies of energy production and price, it is becoming urgent to reduce energy consumption in buildings. The choice of materials for a building with a high energy efficiency becomes much more important and strategies for reducing the use of primary energy for the production of materials and components becomes key. Renewable building materials should already be integrated into the early phases of building planning. The positive trend towards wooden construction is dictated by international guidelines, where a wooden building is an important starting point, not only for low-energy, but also lowemission building with exceptional health and safety aspects. In Europe, the most comprehensive and widely used is a concept of ultralow energy house, more precisely, the passive house concept. Most Slovenian buildings combine contemporary styling with a degree of energy efficiency that comes close to passive house standards. It is widely recognized that the Slovenian construction industry is relatively advanced in the field of low energy buildings. In the light of the growing importance of energy-efficient building methods, it could be said that timber passive house would play an increasingly important role in the future.

    With the rapid economic development, energy consumption of China has been the second place in the world next to the USA. Usually, measuring energy consumption intensity or efficiency applies heat unit which is joule per gross domestic production (GDP) or coal equivalent per GDP. However, this measuring approach is only oriented by the conversion coefficient of heat combustion which does not match the real value of the materials during their formation in the ecological system. This study applied emergy analysis to evaluate the energy consumption intensity to fill this gap. Emergy analysis is considered as a bridge between ecological system and economic system, which can evaluate the contribution of ecological products and services as well as the load placed on environmental systems. In this study, emergy indicator for performing energy consumption intensity of primary energy was proposed. Industrial production is assumed as the main contributor of energy consumption compared to primary and tertiary industries. Therefore, this study validated this method by investigating the two industrial case studies which were Dalian Economic Development Area (DEDA) and Fuzhou economic and technological area (FETA), to comparatively study on their energy consumption intensity between the different kinds of industrial systems and investigate the reasons behind the differences. The results show that primary energy consumption (PEC) of DEDA was much higher than that of FETA during 2006 to 2010 and its primary energy consumption ratio (PECR) to total emergy involvement had a dramatically decline from year 2006 to 2010. In the same time, nonrenewable energy of PEC in DEDA was also much higher than that in FETA. The reason was that industrial structure of DEDA was mainly formed by heavy industries like petro-chemistry industry, manufacturing industries, and high energy-intensive industries. However, FETA was formed by electronic business, food industry, and light industries. Although

    Clavensjoe, B.

    1997-01-01

    The study comprises 31 single-dwelling houses where remedial actions were carried out in the 1980s. In all of them the radon concentrations have increased more than 30% according to recent control measurements. Radon sources are building material as well as the soil. The remedial actions dealt with ventilation systems, leakage through the basement floor, air cushions, sub-slab suction or radon wells according to the original problems. Causes for the increase varied: In many houses with soil radon problems, the installation of a normal mechanical ventilation system is not a good remedial action. In some houses on a ground with high permeability and high radon content in the soil air, the radon concentration may increase by the lowering of the indoor air pressure. In other houses the increase was a measurement effect, where sites/rooms were confused. Living related causes were identified in a number of cases, where fan speeds were reduced for energy conservation/noise reduction purposes or different use of windows airing had occurred. Extension of the dwelling space without changing the ventilation system caused the increase in one house. 23 refs

    2011-01-01

    In the last years, several policies have been proposed by governments and global institutions in order to improve the efficient use of energy in industries worldwide. However, projects in industrial motor systems require new approach, mainly in decision making area, considering the organizational barriers for energy efficiency. Despite the wide application, multicriteria methods remain unexplored in industrial motor systems until now. This paper proposes a multicriteria model using the PROMETHEE II method, with the aim of ranking alternatives for induction motors replacement. A comparative analysis of the model, applied to a Brazilian industry, has shown that multicriteria analysis presents better performance on energy saving as well as return on investments than single criterion. The paper strongly recommends the dissemination of multicriteria decision aiding as a policy to support the decision makers in industries and to improve energy efficiency in electric motor systems. - Highlights: → Lack of decision model in industrial motor system is the main motivation of the research. → A multicriteria model based on PROMETHEE method is proposed with the aim of supporting the decision makers in industries. → The model can contribute to transpose some barriers within the industries, improving the energy efficiency in industrial motor system.

    The purpose of this directory is to provide a basis for market development activities through a location listing of key trade associations, trade periodicals, and key firms for three target groups. Potential industrial users and potential IPH system designers were identified as the prime targets for market development activities. The bulk of the directory is a listing of these two groups. The third group, solar IPH equipment manufacturers, was included to provide an information source for potential industrial users and potential IPH system designers. Trade associates and their publications are listed for selected four-digit Standard Industrial Code (SIC) industries. Since industries requiring relatively lower temperature process heat probably will comprise most of the near-term market for solar IPH systems, the 80 SIC's included in this chapter have process temperature requirements less than 350/sup 0/F. Some key statistics and a location list of the largest plants (according to number of employees) in each state are included for 15 of the 80 SIC's. Architectural/engineering and consulting firms are listed which are known to have solar experience. Professional associated and periodicals to which information on solar IPH sytstems may be directed also are included. Solar equipment manufacturers and their associations are listed. The listing is based on the SERI Solar Energy Information Data Base (SEIDB).
