Full Text Available The provision of adequate, good or quality housing for the population has always been a major challenge and task for most nations in the world particularly the developing countries. As such various measures have been undertaken towards this end. However, the major constraint or problem in this respect has always been in defining the criteria for quality housing and establishing the standards of quality housing particularly with respect to the parameters in the determination of quality as some of the parameters are subjective and contextual such as psychological, cultural and environmental aspects. This paper is aimed at discussing the concept of quality housing and establishing the parameters and theoretical framework which can be used by researchers, town planners, architects, policy makers and others in the formulation of criteria / guidelines for the planning and design of quality housing.

This pilot study investigates the impact of active design (AD) strategies on physical activity (PA) among adults living in two Leadership in Energy and Environmental Design (LEED) certified affordable housing developments in the South Bronx, New York. One building incorporates LEED Innovation in Design (ID) Credit: Design for Health through Increased Physical Activity. Tenants in an affordable housing building (AH) incorporating active design strategies completed PA self-assessments at their lease signing and one year later in 2015. Trained research assistants obtained body measurements. Residents of neighboring non-AD affordable housing (MCV) served as a comparison. Thirty four adults were recruited from AH and 29 from MCV, retention was 56% (n = 19) and 52% (n = 15) respectively at one year. The two groups' body mass index (BMI) and high-risk waist-to-hip ratio (WHR) were not statistically significantly different when analyzed as continuous variables, although BMI category had a greater decline at AH than at MCV (p = 0.054). There was a 31.5% increase in AH participants meeting MPA requirements and a statistically significant improvement in females (p = 0.031); while there was no change in the MCV participants overall or when stratified by gender. AH participants were significantly more likely to have reported increased stair use and less likely to have reported no change or decreased stair use than participants from MCV participants (p = 0.033). Housing has a role in individual health outcomes and behavior change, broad adoption of active design strategies in affordable housing is warranted to improve physical activity measures.

Full Text Available The sustainable renewal of social housing can only be tackled nowadays with the help of design strategies which are able to deal with and coordinate three key issues: the transformation of housing requisites, the deployment of new operational and financial models for carrying out interventions, and the optimization of energy and material resources. The Social Housing cluster was set up a few months ago in the SITdA to coordinate multi-disciplinary research projects exploring the economic, social and environmental feasibility of experimental interventions designed to upgrade the existing built heritage in the light of the most recent energy standards, while at the same time responding to the new housing requisites emerging in the various regional contexts throughout Italy.

Living closer to the environment: Housing design concept

Directory of Open Access Journals (Sweden)

Kosorić Vesna

2011-01-01

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

Matzie, R.A.; Daleas, R.S.; Miller, D.D.

1980-11-01

As part of the US Department of Energy's Advanced Reactor Design Study, various nonbackfittable PWR design modifications were evaluated to determine their potential for improved uranium utilization and commercial viability. Combustion Engineering, Inc. contributed to this effort through participation in the Battelle Pacific Northwest Laboratory industrial assessment of such design modifications. Seven modifications, including the use of higher primary system temperatures and pressures, rapid-frequent refueling, end-of-cycle stretchout, core periphery modifications, radial blankets, low power density cores, and small PWR assemblies, were evaluated with respect to uranium utilization, economics, technical and operational complexity, and several other subjective considerations. Rapid-frequent refueling was judged to have the highest potential although it would probably not be economical for the majority of reactors with the design assumptions used in this assessment

Low-cost housing design and provision: A case study of Kenya

Science.gov (United States)

Kabo, Felichism W.

Shelter is as basic a human need as food and water. Today, many people in Third World countries live in sub-standard housing, or lack shelter altogether. Prior research addresses either one of two housing dimensions: broader provision processes, or specific aspects of design. This dissertation is an effort at addressing both dimensions, the underlying premise being that their inter-connectedness demands an integrative approach. More specifically, this dissertation is a combined strategy case study of housing design and provision in Kenya, a sub-Saharan African country with serious shelter problems. A majority of Kenya's urban population lives in slums or squatter settlements. This dissertation covers four major areas of housing design and provision in Kenya: building materials, user preferences for building materials and housing designs, interior layouts, and the organizational context of the housing sector. These four areas are theoretically unified by Canter's (1977) model of place. Each of the first three areas (housing design) relates to one or more of the three domains in the model. The fourth area (housing provision) pertains to the model's context and framework. The technical building materials research reveals the feasibility of making low-cost materials (soil-cements) with satisfactory engineering performance. The research in preference for building materials reveals that the two independent variables, soil and mix, have a significant effect on potential users' ratings. The housing preference study reveals that of the four independent variables, design and type had a significant effect on potential users' ratings, while materials and construction method did not have a significant effect. The interior layout studies reveal important associations between spatial configurations and a key space (the kitchen), and between configuration and conceptualizations of living, cooking, and sleeping spaces. The findings from the studies of preferences and interior

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

Designing Sustainable Urban Social Housing in the United Arab Emirates

2017-08-01

Full Text Available The United Arab Emirates is experiencing a challenging turn towards sustainable social housing. Conventional neighborhood planning and design principles are being replaced by those leading to more sustainable urban forms. To trace this challenging move, the research has investigated the degree of consideration of sustainable urban design principles in two social housing neighborhoods in Al Ain City in Abu Dhabi Emirate, UAE. The first represents a conventional urban form based on the neighborhood theory; the other represents the new sustainable design. The ultimate aim is to define the obstacles hindering the full achievement of a sustainable urban form in this housing type. To undertake research investigations, a matrix of the design principles of sustainable urban forms has been initiated in order to facilitate the assessment of the urban forms of the two selected urban communities. Some qualitatively measurable design elements have been defined for each of these principles. The results of the analysis of the shift from ‘conventional’ to ‘sustainable’ case studies have revealed some aspects that would prevent the attainment of fully sustainable urban forms in newly designed social housing neighborhoods. Finally, the research concludes by recommending some fundamental actions to help meet these challenges in future design.

Evaluation of Mass Housing at the Pre-Design Stage

Directory of Open Access Journals (Sweden)

Kozan UZUNOĞLU

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.

A Generative Computer Model for Preliminary Design of Mass Housing

Full Text Available Today, we live in what we call the “Information Age”, an age in which information technologies are constantly being renewed and developed. Out of this has emerged a new approach called “Computational Design” or “Digital Design”. In addition to significantly influencing all fields of engineering, this approach has come to play a similar role in all stages of the design process in the architectural field. In providing solutions for analytical problems in design such as cost estimate, circulation systems evaluation and environmental effects, which are similar to engineering problems, this approach is being used in the evaluation, representation and presentation of traditionally designed buildings. With developments in software and hardware technology, it has evolved as the studies based on design of architectural products and production implementations with digital tools used for preliminary design stages. This paper presents a digital model which may be used in the preliminary stage of mass housing design with Cellular Automata, one of generative design systems based on computational design approaches. This computational model, developed by scripts of 3Ds Max software, has been implemented on a site plan design of mass housing, floor plan organizations made by user preferences and facade designs. By using the developed computer model, many alternative housing types could be rapidly produced. The interactive design tool of this computational model allows the user to transfer dimensional and functional housing preferences by means of the interface prepared for model. The results of the study are discussed in the light of innovative architectural approaches.

The Nunavut Housing Corporation (NHC) is responsible for improving the housing and living conditions in communities throughout Nunavut. In response to the current housing shortage, NHC recently initiated a joint project with Canada Mortgage and Housing (CMHC) to develop a sustainable solution to housing in the Arctic. The result was a new energy efficient row house design called the NHC 5-Plex which has become a model for a culturally responsible housing design that meets the needs of Inuit families. This paper presented the design and development process undertaken for this project. It also described how the integration of new construction materials and products designed for cold climates, strategic project management, and cooperation between the NHC and CMHC were used to address the goals of energy efficiency and affordability for Arctic housing. Energy conservation calculations were presented along with the comparative and cost analysis used for the project. The energy modelling of the building performance was undertaken through a technical and design review of windows and insulating materials for energy efficiency, flame ratings, combustibility, sound transmission and water permeability. The heating and ventilation strategies were also evaluated in an effort to address issues of indoor air quality. It was concluded that in order to address the challenge of rising energy costs, the R value in the NHC 5-plex should be increased and the energy savings should be monitored. 3 refs., 6 figs.

2016-01-07

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

Performing accountability: Making environmental credentials visible in housing design

International Nuclear Information System (INIS)

Shaw, Isabel; Ozaki, Ritsuko

2015-01-01

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

Following the events at Fukushima, Canadian Nuclear Power Plants (NPP) procured equipment and initiated modifications to improve response capability for Beyond Design Basis Accidents (BDBA). These changes were not typical of other design modifications to the nuclear power plants and reinforced the need for additional guidance for modifications to address BDBA. This paper describes the guidance that was developed to guide the design, procurement, installation, operation, and maintenance of equipment and modifications to mitigate BDBAs. The guidance developed prescribes a graded approach based on a categorization of the nature of the modification. Four categories of modifications are introduced, with the distinction being the degree of interface with existing design basis systems, structures and components (SSCs). This has resulted in a cost-effective means of implementing additional capability to mitigate BDBA conditions, and yet ensure the design basis capability of SSCs is maintained. (author)

Development of Conceptual Framework for Design Improvement in Urban Housing of Karachi, Pakistan

2011-04-01

Full Text Available Need of housing and need of quality housing are two issues which remained the subject of research and interest to researchers and designers. It is generally observed that not all designers are fully aware of consequences of their design and only through post occupational survey; the designer usually realizes that what mistakes or bad decisions they have made during design process. Unfortunately, such unforeseen conditions are common in residential building projects in developing regions. This research has identified the causes of design deficiencies and their effects on residential building at the post occupational stage in Karachi Pakistan. In this context housing designs and conditions have been closely monitored and issues of deficient design have been identified. Furthermore, this research has circumscribed the implication of deficient design faced by users of private housing in Karachi. The study has established the criteria that these problems affect users through unplanned maintenance to major repairs, leading to danger of collapse. In order to evaluate these effects on buildings, a case study of private housing projects was conducted in Karachi, a metropolitan city of Pakistan. The collected research data was analysed through SPSS computational software and interpreted to understand the far reaching effects and implications of design deficiencies in the selected site of housing stocks. Based on literature review and findings of research, the study has eventually proposed a conceptual framework for improving design practice.

LESS SPACE, MORE SPATIALITY FOR LOW-INCOME HOUSING UNITS IN EGYPT: IDEAS FROM JAPAN

Directory of Open Access Journals (Sweden)

Nermine Abdel Gelil

2011-07-01

Full Text Available In 1996, the Egyptian government launched a national housing project for low-income families. To minimize cost, it has progressively reduced units’ sizes. Numerous surveys indicate that unit specifications were based on political and economic criteria, rather than on users’ needs, which resulted in the recurrence of the persistent phenomenon of individual modifications. A number of scholars and architects concerned with this phenomenon are advocating the revival of the social design principles of traditional Cairene houses (16th –19th century after adapting them to contemporary needs. However, they provide no concrete solutions as to how to achieve this in small-scale units located in multi-storey buildings. During my research in Japan, I was introduced to traditional middle class urban houses. Their practical designs used to resolve issues of privacy, internal flexibility, storage, and family growth can be beneficially applied to housing units in Egypt. This paper first explains why relying solely on traditional housing designs to resolve social issues associated with low-income units in Egypt is both fanciful and incomplete, then discusses why ideas from Japanese homes can be beneficially applied to low-income housing units in Egypt. Third, this paper examines issues in these units and the resultant modifications by Egyptian households. Next, it analyzes concepts of spatial organization, modular systems, partitioning, and storage in traditional middle class urban houses in Japan. Finally, this paper formulates proposals for fulfilling the social needs of occupants in Egypt by integrating these ideas into low-income housing units.

The provision of houses for low-income people who do not have a home worthy of being one of the major problems in the city of Gorontalo, because the community in establishing the house only pay attention to their wants and needs in creating a healthy environment, the beauty of the city and the planning of the home environment in accordance with the culture of the people of Gorontalo. In relation to the condition, the focus of this research is the design of housing based on local architecture as residential house so that it can be reached by a group of low income people with house and environment form determined based on family development, social and economic development of society and environment which take into account the local culture. Stages of this research includes five (5) stages, including the identification phase characteristics Gorontalo people of low income, the characteristics of the identification phase house inhabited by low-income people, the stage of identification preference low-income households, the phase formation house prototype and the environment, as well as the stage of formation model home for low-income people. Analysis of the model homes for low-income people using descriptive analysis, Hierarchical Cluster Analysis, and discrimination analysis to produce a prototype of the house and its surroundings. The prototype is then reanalyzed to obtain the model home for low-income people in the city of Gorontalo. The shape of a model home can be used as a reference for developers of housing intended for low-income people so that housing is provided to achieve the goals and the desired target group.

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

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.

Disasters are recurring to global problems, which results in homelessness. The affected region had economical, environmental and social problems as well. In relief and reconstruction phases, the need for integrated management appeared in order to use the national sources actively and productively. Especially housing implementations had an important role for future development of the affected region. For accelerating the reconstruction of the region and forming a sustainable community, which maintains itself socially, environmentally and economically over time; energy usage for construction should be kept to a minimum. Past research in Turkey shows that the cost of temporary houses (to be used as the short term shelter) had a ratio of 10-15% of the total expenses of whole construction activity. For saving money and protecting the environment and conserving scarce resources, the affected region must consider the option of temporary houses to meet their short and long-term need during the reconstruction process. After the end of usage, temporary houses should be able to be re-used for the same or new function. This study is a test of re-design and re-use of a temporary housing site; by using recycled materials, minimum energy and voluntary participation so that this site can finally become a permanent housing site.

Development of lightweight flexible materials for electromagnetic interference shielding has obtained increased attention in recent years particularly for clothing, textiles in-house use and technical applications especially in areas of aircraft, aerospace, automobiles and flexible electronics such as portable electronics and wearable devices. There are many references in the literature concerning development and investigation of electromagnetic shielding lightweight flexible materials especially textile based with different electrically conductive additives. However, only little attention is paid to designing and enhancing the properties of these special fabrics by textile finishing processes. Laser technology applied as a physical treatment method is becoming very popular and can be used in different applications to make improvement and even overcome drawbacks of some of the traditional processes. The main purpose of this study is firstly to analyze the possibilities of transferring design onto the surface of electrically conductive fabrics by laser beam and secondly to study of effect of surface modification degree on performance of conductive fabric including electromagnetic shielding ability and mechanical properties. Woven fabric made of yarns containing 10% of extremely thin stainless steel fiber was used as a conductive substrate.

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

The population of sub-Saharan Africa is currently estimated to be 1245 million and is expected to quadruple by the end of the century, necessitating the building of millions of homes. Malaria remains a substantial problem in this region and efforts to minimise transmission should be considered in future house planning. We studied how building elements, which have been successfully employed in southeast Asia to prevent mosquitos from entering and cooling the house, could be integrated in a more sustainable house design in rural northeastern Tanzania, Africa, to decrease mosquito density and regulate indoor climate. In this field study, six prototype houses of southeast Asian design were built in in the village of Magoda in Muheza District, Tanga Region, Tanzania, and compared with modified and unmodified, traditional, sub-Saharan African houses. Prototype houses were built with walls made of lightweight permeable materials (bamboo, shade net, or timber) with bedrooms elevated from the ground and with screened windows. Modified and unmodified traditional African houses, wattle-daub or mud-block constructions, built on the ground with poor ventilation served as controls. In the modified houses, major structural problems such as leaking roofs were repaired, windows screened, open eaves blocked with bricks and mortar, cement floors repaired or constructed, and rain gutters and a tank for water storage added. Prototype houses were randomly allocated to village households through a free, fair, and transparent lottery. The lottery tickets were deposited in a bucket made of transparent plastic. Each participant could draw one ticket. Hourly measurements of indoor temperature and humidity were recorded in all study houses with data loggers and mosquitoes were collected indoors and outdoors using Furvela tent traps and were identified with standard taxonomic keys. Mosquitoes of the Anopheles gambiae complex were identified to species using PCR. Attitudes towards the new house

Nurdini, Allis; Yovita, Wanda; Negri, Patriot

2017-12-01

Recently the discussion about resiliency and housing design has been fast developed, including design for housing on riverfront as marginal area that usually occupied by low income people. The low income people generally will be the worst affected community in flood disaster situation, because of their un-affordability to achieve quality housing design. In other side, the funding support capacity especially from the local government is limited, so that the resilient environment also need to be supported by the community itself. In this context, the study about low income people's affordability to achieve resilient housing design is essential. This study was conducted to identify two important points: the design choice and the affordability level of resilient housing from the community viewpoints. Kampong Cieunteung, in Bale Endah Area, Bandung Regency is chosen as a case study, because this area annually experience severe flood from overflow of the Citarum River branch. In preliminary research phase, approximately 60% of the Kampong Cieunteung's resident need to stay and become indication that the community need resilient housing design to accommodate their live hood. The next phase, the contingent valuation method was implemented to gain resilient design choice and affordability perspective from the community. It is concluded that the community have ability to choose the resilient housing design based on their aspiration and based on their ability to pay. The result indicates that resilient housing design should have character of optional, module co-operational, and incremental to be afforded by the low income people.

The Westinghouse Savannah River Company (WSRC) is preparing to retrieve high level waste (HLW) from Tank 18 in early FY03 to provide feed for the Defense Waste Processing Facility (DWPF) and to support tank closure in FY04. As part of the Tank 18 project, WSRC will install a single Advanced Design Mixer Pump (ADMP) in the center riser of Tank 18 to mobilize, suspend, and mix radioactive sludge in preparation for transfer to Tank 7. The use of a single ADMP is a change to the current baseline of four (4) standard slurry pumps used during previous waste retrieval campaigns. The ADMP was originally conceived by Hanford and supported by SRS to provide a more reliable and maintainable mixer pump for use throughout the DOE complex. The ADMP underwent an extensive test program at SRS between 1998 and 2002 to assess reliability and hydraulic performance. The ADMP ran for approximately 4,200 hours over the four-year period. A detailed tear down and inspection of the pump following the 4,2 00-hour run revealed that the gas mechanical seals and anti-friction bearings would need to be refurbished/replaced prior to deployment in Tank 18. Design modifications were also needed to meet current Authorization Basis safety requirements. This report documents the modifications made to the ADMP in support of Tank 18 deployment. This report meets the requirements of Tanks Focus Area (TFA) Milestone 3591.4-1, ''Issue Report on Modifications Made to the ADMP,'' contained in Technical Task Plan (TTP) SR16WT51, ''WSRC Retrieval and Closure.''

Penner, Barbara

2018-01-01

The Cornell Kitchen (1950-55) was produced at Cornell University by a multidisciplinary team with expertise in home economics, engineering, architecture, and psychology. It promised to deliver rational design, functional principles, aesthetic appeal, and emotional satisfaction in one prefabricated, easy-to-install package. This article sets out the kitchen's history from its design to its field-testing phase to its impact on postwar kitchens. It argues that the kitchen represents an important effort to approach housing in a more scientific way; scientific methods were deployed to understand both the physical and socio-psychological problems of dwelling. The project also sought to introduce a specific model for leveraging housing research into the real world, partnering with industry to mass produce scientific designs. Social scientific methods were hence used to create not only more livable but also more saleable products in an effort to appeal to manufacturers and consumers alike.

Full Text Available Abstract Background Identifying the housing preferences of people with complex disabilities is a much needed, but under-developed area of practice and scholarship. Despite the recognition that housing is a social determinant of health and quality of life, there is an absence of empirical methodologies that can practically and systematically involve consumers in this complex service delivery and housing design market. A rigorous process for making effective and consistent development decisions is needed to ensure resources are used effectively and the needs of consumers with complex disability are properly met. Methods/Design This 3-year project aims to identify how the public and private housing market in Australia can better respond to the needs of people with complex disabilities whilst simultaneously achieving key corporate objectives. First, using the Customer Relationship Management framework, qualitative (Nominal Group Technique and quantitative (Discrete Choice Experiment methods will be used to quantify the housing preferences of consumers and their carers. A systematic mixed-method, quasi-experimental design will then be used to quantify the development priorities of other key stakeholders (e.g., architects, developers, Government housing services etc. in relation to inclusive housing for people with complex disabilities. Stakeholders randomly assigned to Group 1 (experimental group will participate in a series of focus groups employing Analytical Hierarchical Process (AHP methodology. Stakeholders randomly assigned to Group 2 (control group will participate in focus groups employing existing decision making processes to inclusive housing development (e.g., Risk, Opportunity, Cost, Benefit considerations. Using comparative stakeholder analysis, this research design will enable the AHP methodology (a proposed tool to guide inclusive housing development decisions to be tested.

Gampe, F.; Raitt, D.

2002-01-01

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

The effect of house building design and environment on the fungal movement in the houses of 41 bronchial asthma (BA) patients has been investigated by examining house dust. The presence and composition of fungi were determined and compared in relation to building structure, house age, size of living room, main flooring material, presence of a living-room rug or air purifier, and frequency of vacuum cleaning. Among these elements, fungal CFU apparently varied only between building structure: wooden-board houses had significantly higher numbers of fungi than reinforced concrete houses (p prefabricated houses had significantly higher numbers of fungi than reinforced concrete houses (p < 0.05). Classification of the types of fungi present in the house dust of BA patients showed that, regardless of the building designs, there were high levels of osmophilic fungi (group A) and fungi that survive at relatively dry conditions (group B), whereas fungi that survive in very wet conditions (group D) were present at low frequency.

Various De-NOx methods have been recently adopted in China to control NOx emissions including Selective Non-Catalytic Reaction (SNCR) technology. Usually, the design of SNCR system is carried out after the combustion modification technologies, such as low NOx burner (LNB) and over fire air (OFA), have already been installed and in operation. This article discusses how to design the SNCR system parallel to the combustion modification. The SNCR process design consists of three steps: (1) boiler baseline test, (2) computational fluid dynamics simulation (CFD) facilitated design and (3) SNCR system performance predictions and optimizations. The first step is to conduct boiler baseline test to characterize the boiler operating conditions at a load range. The test data can also be used to calibrate the CFD model. The second step is to develop a three-dimensional boiler coal combustion CFD model to simulate the operation of the boilers at both baseline and post combustion modification conditions. The simulation reveals velocity, temperature and combustible distributions in the furnace. The last step is to determine the position and numbers of the injectors for SNCR reagent. The final field tests upon the project completion have shown that the average SNCR De-NOx efficiency has reached 35.1% with the maximum removal efficiency of 45% on full load. The project also couples the SNCR and SCR (Selective Catalytic Reduction) technologies. The combined removal efficiency of combustion modifications, SNCR and SCR is higher than 82%. This paper shows a successful example for retrofitting aged power-generating units with limited space.

Work Models in the Design Process for House Interior and Exterior: Physical or Virtual?

Science.gov (United States)

Bradecki, Tomasz; Uherek-Bradecka, Barbara

2017-10-01

The article presents the effects of research on different types of models of single family houses and multifamily houses. Exterior layout and interior functional layout are the main drivers for the final result of a design. Models are an important medium for presentation of architectural designs and play a pivotal role in explaining the first idea to people and potential clients. Although 3D models have unlimited possibilities of representation, some people cannot understand or ‘feel’ the designed space. The authors try to test how to combine the interior and the exterior in a single synthetic model. Several models of different houses have been presented in the article. All the case studies were developed with physical models, 3D models, and 2D hand sketches. The main focus of the work with the models was to achieve a coherent vision for future feeling of open space in designed houses. The research shows how synthetic models might be helpful in the design process. The research was carried in the URBAN model research group (urbanmodel.org, Gliwice, Poland) that consists of academic researchers and architects. The models reflect architectural experience gathered by the authors during their work on theoretical models, architectural projects and by supervision on site during construction site visits. Conclusions might be helpful for developers, architects, interior designers and architecture students.

Lucas Rosse Caldas

Full Text Available Abstract This study evaluated the CO2eq emissions during the life cycle of two social housing projects in the city of Brasilia. A house of ceramic brick masonry was compared to a light steel framing one. The life cycle carbon emissions assessment (LCCO2A with a cradle-to-grave approach was used. The relation between the thermal performance of the wall systems and CO2eq emissions in the operational phase of the houses were evaluated using the DesignBuilder software. In addition, six scenarios composed of three CO2eq emission factors from the Brazilian electrical grid and two schedules of occupation of houses (full and part time were evaluated. The brick masonry house presented less CO2eq emissions than the light steel framing one. For both houses, the operational phase was the most significant regarding the total CO2eq emissions (50% to 70%, followed by the construction (20% to 30%, maintenance (11% to 20% and end-of-life (lower than 1% phases. The results also showed the importance of considering different CO2eq emission factors for the Brazilian context in the operational phase. Finally, based on the results obtained, design guidelines for low carbon social housing were proposed.

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

The 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.

An approach to nuclear plant design and modification support for Russian-designed plants in Eastern Europe

2002-01-01

The Western nuclear countries have embarked on numerous programs to improve the safety of the Russian-designed nuclear power plants. In Russian-designed plants in Eastern Europe, plant management is being asked for the first time to decide which safety projects to implement and is finding itself lacking in nuclear safety analytical tools and practices, funds, and experience with project management and project engineering skills and tools. Some of the major areas where assistance is needed are: 1) Defining plant weaknesses toward nuclear safety. 2) Evaluating and grading the importance to safety of proposed modification. 3) Project Planning and Scheduling using computer based scheduling software. 4) Project Finance Development and Management using well defined cash flow management techniques. 5) Contract Management and Change Control. 6) Interface Management. Each of these areas requires a significant amount of discussion to understand the issues and problems associated with them. However, this paper is limited to the Project Management areas. This paper encourages the use of a design engineering firm experienced in safety practices and associated management and technical skills to serve as the Owner's Engineer/Project Management Consultant for the program period for a Russian-designed plants located outside Russia. This approach would allow for the availability and transfer of knowledge of safety practices to plant personnel and owners engineers at nuclear plants outside Russia, improving their nuclear safety culture. The plant personnel would control plant modernizations and upgrades based upon a proven and well-defined process for detailed project definition, configuration change control, and project management. This offers the opportunity to enhance the long-term safety culture by developing plant personnel knowledgeable of the safety practices, plant design basis, developing a modification control process enabling them to control the design basis through future

Universal Design as a Booster for Housing Quality and Architectural Practice.

Norwegian central government has for the last decade increasingly focused on universal design. Fundamental changes in the Norwegian building code and corresponding regulations in 2010 give an apparently clear framework for the implementation of accessibility and universal design. However, it seems that neither increased awareness of accessibility requirements and universal design, nor compliance with the building code guarantees improvement of housing quality and usability. The Norwegian regulations have gone further in the direction of performance requirements than most other countries. This applies to all types of requirements, including requirements for usability, functionality and accessibility. Hardly any specifications are to be found in the regulations. Ideally, this lack of specifications should give designers the opportunity to develop innovative answers and hence to respond to different contexts and needs. Still, many architects and builders ask for clear specifications, in order to simplify and speed up design processes and make control of solutions easier. Many architects understand guidelines as minimum requirements, and are thus reproducing the identical solutions without considering the context and the needs of the users. They see accessibility as another regulatory pressure and requirements as restrictions rather than positive incentives. However, there are examples of designers who have internalised the regulatory framework and thus are able to create and integrate inclusive design in their daily work. Based on recent research conducted by SINTEF Building and Infrastructure and financed by the Norwegian State Housing Bank, this paper presents examples of practice where dwellings have been developed within a framework of universal design. Focus of the research has been on the approach of the design team and their understanding and use of the regulatory framework in order to create better homes in dialogue with the building authorities.

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

Designing for an imagined user: Provision for thermal comfort in energy-efficient extra-care housing

International Nuclear Information System (INIS)

Lewis, Alan

2015-01-01

Regarded as one solution to the problem of how to enable older people to retain their independence, extra-care housing, where each resident has their own self-contained dwelling and access to communal facilities and to care, has received extensive funding in recent years. Implicit in the concept of specialist housing is the notion of ‘special’ occupants, imagined older people. Adopting a socio-technical approach, this paper considers how ideas about ageing inform those aspects of extra-care-housing-design that relate to thermal comfort. The paper draws on semi-structured interviews with 13 people involved in the design, development and management of UK-based extra-care housing. Participants characterised imagined occupants as vulnerable to cold, at risk from fuel poverty and liable to be burned by hot surfaces or fall from high windows. These user representations were reportedly inscribed into the design of extra-care housing schemes through the inclusion of building features such as communal heating, under-floor heating, restricted window opening and heated corridors. The utilisation of stereotypical user representations of older people raises questions, given that older people's thermal comfort needs can be highly diverse. The paper explores the implications for energy demand. -- Highlights: •Explores the factors that condition energy demand in older people's housing. •Considers how user representations are scripted into building design. •Older occupants characterised as vulnerable to cold and having low incomes. •These user representations affect selection of thermal technologies. •Priority given to keeping occupants warm, leading to possible risk of overheating

Fox, Siobhan; Kenny, Lorna; Day, Mary Rose; O'Connell, Cathal; Finnerty, Joe; Timmons, Suzanne

2017-01-01

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

Gerontological perspectives on crime and nuisance: the elderly critically evaluate housing designs in the British city.

Science.gov (United States)

Cozens, Paul; Hillier, David; Prescott, Gwyn

2002-01-01

This paper investigates the perceptions of the elderly in relation to crime and nuisance and the fear of crime associated with stereotypical British housing designs. Demographically, this diverse though highly urbanized group continues to grow; group members' observations, therefore, have increasing social relevance and political importance and are crucial for assessing and informing both current policy and the evolution of future policy initiatives. Crime Prevention Through Environmental Design (CPTED) has become popular once again in America, Australia, Canada, South Africa, as well as in Europe and Britain. A crucial dimension to this theory concerns the perception of "territoriality," "surveillance," and "image" within the design of the built environment derived from Newman's "Defensible Space" concepts (1973). This paper presents and discusses the ways in which the elderly associate crime and nuisance with a range of traditional housing designs. The findings strongly reinforce Newman's theory. The paper concludes that the design and, perhaps more importantly, the management of residential housing influence the perceived levels of crime, nuisance, and fear of crime, and the "defensible" qualities of each specific design. Such perceptions will arguably affect elderly people's ability to maintain their privacy, dignity, and autonomy, their physical and psychological well-being, and their social inclusion. Policy implications for housing the elderly safely within the community are reviewed.

Proposal for modification to forward module design

International Nuclear Information System (INIS)

Lindsay, S.; Taylor, G.

2000-01-01

Concern for the baseline forward module thermal and mechanical viability has led to a proposed modification to the design described here. In view of the tight schedule to finalise the module design, proposed changes are constrained so that calculations and proto typing can be carried out without major changes to the key elements in the module. The following constraints were considered in the process of this work: 1. The hybrid contributes the bulk of the power to be removed from the module. 2. The temperature and its variation across the detector are the key specifications for the cooling design of the module. The hybrid temperature may impact via (secondary) convection and radiation heating, but its operation temperature is not assumed to be the major constraint. 3. The forward hybrid design is well advanced and represents a large effort that should be preserved. 4. The overall design of the module, in particular overall dimensions and placement of precision mounting points is well advanced. Assembly jigs based upon these dimensions are also advanced. The following problems are addressed by the current proposal: 1. The constraint of the small cooling point required to cool both the hybrid and the detector in the baseline is considered a serious limitation demanding high performance in the design and implementation of this contact in the baseline. 2. The small surface area of this contact is critical. Concerns that distortions of the block or relative distortions in the module between the detector and the hybrid, might further reduce the critical effective contact area, as well as possibly causing other problems, give further impetus to the proposed design modification. 3. Thermo-mechanical stress due to the cooling points at both ends of the module. 4. Lack of support of the hybrid near to the cable connectors. 5. Close proximity of the cooling pipe to the front-end electronics and the wire bonds. The proposal involves extending the hybrid substrate with two

Socio-economic growth in Vietnam greatly depends on the new rural development process in this country; the work is considered a strategic position in national development. Thus, the study of the principles of the architectural design of new rural housing solutions in accordance with the New Rural Environment as required by the Vietnam Ministry of Construction has become urgent. Climate change has become a global concern, so the creation of significant impacts by architectural designs to respond to climate change and make the living environment of rural people better is a major demand. Experience has shown that the dogmatic application of current urban-type housing does not reach the requirements of New Rural Housing. This research intends to show that the solutions of the traditional Vietnamese rural house, which retains the advantages of traditional architecture with excellent characteristics that have been challenged over thousands of years, when combined with advanced design methodologies and technologies, will be the appropriate solution for ‘New Rural Housing’.

Design and evaluation of modified screen net house for off-season vegetable raising in composite climate

2009-01-01

Currently the use of conventional screen net houses for off-season vegetable raising in north India composite climate is not so effective and has many constructional and operational limitations like poor structural design, higher constructional cost, no greenhouse effect in winter and higher plant temperatures in summer. Similarly, the use of polyethylene sheet covered greenhouses also has problems like much higher constructional and operational costs and higher inside air temperatures in summers. In this study, modified designs of 500 m 2 (one kanal) and 250 m 2 (half kanal) screen net house have been presented particularly suitable for composite climate (where both winters as well as summers are harsh) as a replacement for conventional net house and polyethylene sheet covered greenhouse design. To make these designs low cost and more effective, low tunnels (covered with low density polyethylene sheet) have been designed and used in winter over the plant rows to generate localized greenhouse effect for faster plant growth. By doing so, average daily air temperature under the tunnels was raised about 9-10 deg. C above the open field air temperature. In this way, huge cost of covering the net house or greenhouse during winter with costly polyethylene sheet could be saved. Similarly, in extreme summer when the ambient air temperature exceeded 40 deg. C (during the fruiting stage of the crop) a 50% shade net was used inside the modified net house at 2.5 m height (instead of using active cooling system) resulting in 4-6 deg. C drop in the plant temperature. Experimental evaluation of the modified net house was conducted during winter and summer months of year 2007-08 (December to June) by growing brinjal crop and compared with conventional net house, polyethylene sheet greenhouse and in open field condition. It was observed that due to the combined effect of low tunnels (in winter) and shade net (in summer), the micro-climatic parameters like air temperature, plant

Understanding of Danish passive houses based on pilot project Comfort Houses

Energy Technology Data Exchange (ETDEWEB)

Brunsgaard, C.

2010-12-15

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

Aluminum die casting is so complex where flow momentum is critical matter in the mould filling process due the high velocity of the liquid metal. Actually, in complex parts the exact calculation of mould filling performance with using experimental knowledge is almost impossible. Aluminum die castings play a definitive role in the manufacturing of lightweight automobile bodies. Hence it is more essential today that these castings be produced with the high quality methods. In this condition the simulation is becoming more important in the designing procedure. This saves time and reduces the cost of the casting system design, which is an advantage of using simulation programs. Also, economical utilization of materials can be obtained when the quantity of test castings is decreased. This paper describes the advantages of the clutch housing die casting mold simulations to achieve better casting system design in High pressure die castings (HPDC). Filling analysis is used to determine the size and location of the gate as well as proper runner system design for ensuring a complete and balanced filling of the clutch housing part.

The Design of Local-Authority Rental Housing for the Elderly That Improves Their Quality of Life

2018-05-01

Full Text Available As the population ages, the demand for suitable rental housing will increase. Suitable housing means housing that can accommodate those impairments that typically correspond with ageing. This paper explores the quality of life (QoL requirements of those elderly with high-care needs who live in rental housing. Using a qualitative case study approach, it examines the living experiences of six elderly people who need assistance and are living in local-authority rental housing in New Zealand. The themes of QoL were identified from the literature and related to the larger themes of; 1. Activities and independence, 2. Sense of control, 3. Privacy, 4. Relationships, 5. Quality of care, and 6. Comfort. The survey consisted of a detailed documentation of the physical environment, followed by interviews with and full-day observations of the residents and their caregivers. The study finds that the design of housing that improves their QoL requires solutions to accommodate the various conflicting needs for their QoL that include those derived from the diversity in the user’s preferences and impairments. In the design of rental housing, there is greater need for additional or reorganized space to accommodate caregivers and visitors, maintain residents’ independence, privacy, and other aspects important for their QoL.

BIPV design study for Renewable Energy Centre and Eco-Energy House

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

Modern housing design: prefabricated and modular design in Frank Lloyd Wright's architecture

Directory of Open Access Journals (Sweden)

Ana Tagliari

2011-12-01

Full Text Available This paper investigates the residential architecture of Frank Lloyd Wright, especially the designs which were conceived from an idea of prefabricated, modular, low-cost, and high-scale construction. Wright's organic designs originated from a material-based grid, which at the same time organized and provided freedom to create spaces and forms. This study reviews Wright's work, from his first Midwest designs that relied on brick, through an intermediary phase in California when he made intense use of concrete blocks, until his last phase, the usonian houses, which featured wood paneling. During his early career, the concept and the methodology of Wright's ideas greatly contributed to a better understanding of his architecture, his apprentices and his followers. The economy and rationalization found in the projects reviewed are of great importance as the analysis of historical proposals helps us understand the topic in question.

Aseismic design of turbine houses of nuclear power plants

International Nuclear Information System (INIS)

Danisch, R.; Labes, M.

1975-01-01

The turbine house does not belong to the safety-related parts of equipment of a nuclear power plant. A special protection against earthquakes is not demanded by the authorities as long as it is proven that safety-related parts of equipment will not be restricted in their function by a collaps of the turbine house. The degree of an aseismic design is largely up to the customer, who has to weigh the risk of costs and availability against the additional costs, that are necessary for the earthquake calculation and for constructive hardening. In comparison to the high-tuned turbine foundations as they are in use in the USA today, low-tuned turbine foundations as a result of helical-spring-support, which are constructed by the KWU exclusively, pose special problems with the aseismic design. This is discussed in the present report. The spring-supported mass constitutes about a quarter of the building-mass. For mechanical reasons the spring elements are chosen in such a way, that the turbine foundation has a natural frequency of approximately 3 Hz. Thus it remains within the same frequency range as the turbine house and within that very range which is particularly amplificated by an earthquake. It is therefore likely that resonance effects as well as oscillation annulment effects may occur. The standardized calculation methods for conventional buildings without safety function such as DIN 4149 (Germany) or SIA 162 (Switzerland) do not cover the oscillation conduct of such a complicate structure. One receives informations about possible relative displacements between the building and the turbine foundation (hammering-effect) and about the stresses on the turbine and other components only by dynamic calculation methods such as the time-history or the response-spectrum method

Thermal design of a modern, two floor, zero energy house in a desert compound

KAUST Repository

Serag-Eldin, M. A.

2010-12-01

The paper presents a thermal analysis and design of a fully equipped, air-conditioned, zero energy house located in a desert compound at 24.5° latitude. Unlike previous designs the home is two floors high, which makes the balancing of energy supply and demand even more challenging. The roof of the house carries an array of retractable Photovoltaic modules and cover. During day light hours the modules convert the incident sun energy into useful electrical power, while shielding the roof from direct sun-radiation. At night time, the roof cover and modules are retracted to expose the roof to the cool night-sky, thus enhancing cooling. The paper employs time-dependent modeling of Solar input and heat transfer to predict the roof, wall and window temperature distributions and cooling loads, as well as energy generated by the modules. With the aid of battery storage, the modules provide the entire energy needs of the house. The paper displays the results of energy balances for three key days of the year which demonstrate that the proposed two floor design is indeed capable of operating without external energy. © 2010 IEEE.

Modification Design of Petrol Engine for Alternative Fueling using Compressed Natural Gas

2013-04-01

Full Text Available This paper is on the modification design of petrol engine for alternative fuelling using Compressed Natural Gas (CNG. It provides an analytical background in the modification design process. A petrol engine Honda CR-V 2.0 auto which has a compression ratio of 9.8 was selected as case study. In order for this petrol engine to run on CNG, its compression had to be increased. An optimal compression ratio of 11.97 was computed using the standard temperature-specific volume relationship for an isentropic compression process. This computation of compression ratio is based on an inlet air temperature of 30oC (representative of tropical ambient condition and pre-combustion temperature of 540oC (corresponding to the auto-ignition temperature of CNG. Using this value of compression ratio, a dimensional modification Quantity =1.803mm was obtained using simple geometric relationships. This value of 1.803mm is needed to increase the length of the connecting rod, the compression height of the piston or reducing the sealing plate’s thickness. After the modification process, a CNG engine of air standard efficiency 62.7% (this represents a 4.67% increase over the petrol engine, capable of a maximum power of 83.6kW at 6500rpm, was obtained.

Centrifugal compressor shape modification using a proposed inverse design method

International Nuclear Information System (INIS)

Niliahmadabadi, Mahdi; Poursadegh, Farzad

2013-01-01

This paper is concerned with a quasi-3D design method for the radial and axial diffusers of a centrifugal compressor on the meridional plane. The method integrates a novel inverse design algorithm, called ball-spine algorithm (BSA), and a quasi-3D analysis code. The Euler equation is solved on the meridional plane for a numerical domain, of which unknown boundaries (hub and shroud) are iteratively modified under the BSA until a prescribed pressure distribution is reached. In BSA, unknown walls are composed of a set of virtual balls that move freely along specified directions called spines. The difference between target and current pressure distributions causes the flexible boundary to deform at each modification step. In validating the quasi-3D analysis code, a full 3D Navier-Stokes code is used to analyze the existing and designed compressors numerically. Comparison of the quasi-3D analysis results with full 3D analysis results shows viable agreement. The 3D numerical analysis of the current compressor shows a huge total pressure loss on the 90 .deg. bend between the radial and axial diffusers. Geometric modification of the meridional plane causes the efficiency to improve by about 10%.

Yamaji, A.; Miyakoshi, J.; Kageyama, T.; Futamura, Y.

1983-01-01

Shielding modification design of the N.S. Mutsu was performed for reducing the radiation doses outside the primary and the secondary shields by providing shields for neutrons streaming through the air gap between the pressure vessel and the primary shield. This was accomplished by replacing parts of the shields and adding new shields in the upper and lower sections of both primary and secondary shields, and also replacing the thermal insulator in the gap. The shielding design calculations were made using one- and two-dimensional discrete ordinates codes and also a point kernel code. Special attention was paid to the calculations of, (1) the neutrons streaming through the gap between the pressure vessel and the primary shield, (2) the radiations transmitted through the radial shield of the core in the primary shield, (3) the radiations transmitted through the upper and lower sections of the secondary shield, and (4) the dose rate equivalent in the accommodation area. Their calculational accuracies were estimated by analyzing various experiments. To support the modification, a variety of experiments and tests were carried out, which were material tests, cooling test of the primary shield, mechanical strength test of the double bottom, trial fabrication tests of new shields, performance degradation test of heavy concrete and duct streaming experiment in the secondary shield.

Well-designed housing is recognised as being an important factor in promoting a good quality of life. Specialised housing models incorporating care services, such as extra care housing (ECH) schemes are seen as enabling older people to maintain a good quality of life despite increasing health problems that can accompany ageing. Despite the variation in ECH building design little is known about the impact of ECH building design on the quality of life of building users. The evaluation of older people's living environments (EVOLVE) study collected cross-sectional data on building design and quality of life in 23 ECH schemes in England, UK. Residents' quality of life was assessed using the schedule for the evaluation of individual quality of life-direct weighting (SEIQoL-DW) and on the four domains of control, autonomy, self-realisation and pleasure on the CASP-19. Building design was measured on 12 user-related domains by means of a new tool; the EVOLVE tool. Using multilevel linear regression, significant associations were found between several aspects of building design and quality of life. Furthermore, there was evidence that the relationship between building design and quality of life was partly mediated by the dependency of participants and scheme size (number of living units). Our findings suggest that good quality building design in ECH can support the quality of life of residents, but that designing features that support the needs of both relatively independent and frail users is problematic, with the needs of highly dependent users not currently supported as well as could be hoped by ECH schemes.

2018-04-01

Since the time varying meshing stiffness of gear system is the key factor affecting gear vibration, it is important to design the meshing stiffness to reduce vibration. Based on the effect of gear modification coefficient on the meshing stiffness, considering the random parameters, reliability optimization design of the gear modification is researched. The dimension reduction and point estimation method is used to estimate the moment of the limit state function, and the reliability is obtained by the forth moment method. The cooperation of the dynamic amplitude results before and after optimization indicates that the research is useful for the reduction of vibration and noise and the improvement of the reliability.

Design and evaluation of a novel magnetorheological brake with coils placed on the side housings

International Nuclear Information System (INIS)

Hung Nguyen, Quoc; Diep Nguyen, Ngoc; Bok Choi, Seung

2015-01-01

In the design of a traditional magnetorheological brake (MRB), coils are often placed on the cylindrical housing of the brake. This results in many disadvantages such as a ‘bottle-neck’ problem of magnetic flux. Moreover, in this design a nonmagnetic bobbin is required, and difficulties in manufacturing and maintenance exist. In order to resolve this problem, in this study a new configuration of MRB with coils placed on the side housings of the brake is proposed, optimally designed and experimentally evaluated. After describing an introduction of the proposed configuration, braking torque of the MRB is analyzed based on the Bingham-plastic rheological model of magnetorheological fluid (MRF). The optimization of the proposed and conventional MRBs is then performed considering maximum braking torque and mass of the brakes. In the optimization, both rectangular and polygonal shapes of the brake housing are considered. Based on the optimal results, a comparison of the performance characteristics of the proposed MRB and the conventional one is undertaken. In addition, an experimental test of the MRBs is conducted, and the results are presented in order to validate the performance characteristics of the proposed MRB. (technical note)

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.

The solarisation of welfare housing: Is passive solar design a boon to those who don`t choose it?

Energy Technology Data Exchange (ETDEWEB)

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

1994-12-31

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

The use of biochar has been suggested as a means of remediating contaminated soil and water. The practical applications of conventional biochar for contaminant immobilization and removal however need further improvements. Hence, recent attention has focused on modification of biochar with novel structures and surface properties in order to improve its remediation efficacy and environmental benefits. Engineered/designer biochars are commonly used terms to indicate application-oriented, outcome-based biochar modification or synthesis. In recent years, biochar modifications involving various methods such as, acid treatment, base treatment, amination, surfactant modification, impregnation of mineral sorbents, steam activation and magnetic modification have been widely studied. This review summarizes and evaluates biochar modification methods, corresponding mechanisms, and their benefits for contaminant management in soil and water. Applicability and performance of modification methods depend on the type of contaminants (i.e., inorganic/organic, anionic/cationic, hydrophilic/hydrophobic, polar/non-polar), environmental conditions, remediation goals, and land use purpose. In general, modification to produce engineered/designer biochar is likely to enhance the sorption capacity of biochar and its potential applications for environmental remediation.

Levels of radon and its short-lived airborne progeny are being measured in a year-long study of 70 houses in four states in the Tennessee Valley. Various methods were used to solicit volunteers with differing degrees of success. Criteria for selection of houses in the study included presence of a lower level with cement floor and one or more block walls in contact with the soil, absence of obvious indications of technologically enhanced sources of radium, and proximity to one of four cities (Knoxville, Chattanooga, Birmingham, or Florence). By design, most houses in the study are in the same neighborhood as at least one other house in the study. Houses range in age from newly constructed to about 40 years old. Most of the houses have more than 2000 square feet of finished floor space. The lower level encompasses a garage in most cases. More complete information pertaining to house characteristics will be gathered in the course of the study. 19 refs., 1 fig

The System for Continuous Observation of Rodents in Home-cage Environment (SCORHE) was developed to demonstrate the viability of compact and scalable designs for quantifying activity levels and behavior patterns for mice housed within a commercial ventilated cage rack. The SCORHE in-rack design provides day- and night-time monitoring with the consistency and convenience of the home-cage environment. The dual-video camera custom hardware design makes efficient use of space, does not require home-cage modification, and is animal-facility user-friendly. Given the system's low cost and suitability for use in existing vivariums without modification to the animal husbandry procedures or housing setup, SCORHE opens up the potential for the wider use of automated video monitoring in animal facilities. SCORHE's potential uses include day-to-day health monitoring, as well as advanced behavioral screening and ethology experiments, ranging from the assessment of the short- and long-term effects of experimental cancer treatments to the evaluation of mouse models. When used for phenotyping and animal model studies, SCORHE aims to eliminate the concerns often associated with many mouse-monitoring methods, such as circadian rhythm disruption, acclimation periods, lack of night-time measurements, and short monitoring periods. Custom software integrates two video streams to extract several mouse activity and behavior measures. Studies comparing the activity levels of ABCB5 knockout and HMGN1 overexpresser mice with their respective C57BL parental strains demonstrate SCORHE's efficacy in characterizing the activity profiles for singly- and doubly-housed mice. Another study was conducted to demonstrate the ability of SCORHE to detect a change in activity resulting from administering a sedative.

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

Directory of Open Access Journals (Sweden)

Ibiyeye AI

2015-05-01

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

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

Hood River Passive House

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

A Proposal for Desert House Design in Egypt Using Passive Ground Cooling Techniques

Full Text Available An area less than 5.5% of Egyptian territory is where most of Egypt‘s population lives in. A narrow strip of land forms the Nile Valley and Delta sector.The National Project for Desert Hinterlands is one of the urban projects targeting rehabilitation of the poor in alternative villages in the near desert to stop urban sprawl over agricultural land and decrease the congestion in the old habitats. Low cost energy efficient houses are the aim of the architect in similar projects taking in consideration the high electricity consumption of Egypt’s residential sector. Based on a literature review, this paper presents a proposal for designing desert dwellings   that accommodates the hot dry climate by incorporating passive elements and using stabilized earth blocks as a local building material. Furthermore, simulation is used to test alternative proposals. The results show that an underground constructed house with a sunken courtyard incorporating an Earth to Air Heat Exchanger System (EAHE can reduce between 42-72% of energy consumption used to achieve thermal comfort compared to contemporary desert housing projects.

Full Text Available Housing and the concept of space associated with this requirement are among the initial attitudes towards the human reign over the nature. The dawn of the structured environment found life with this approach within the nature. Both, housing and the housing design process overlap with the historical development of modern man, and is covered within the concept of architecture today. The contribution made by culture within this period is yet another undeniable fact. While the interaction between architecture and culture are moving forward thereby leaving traces in every era throughout the history, the culture of housing and housing design exhibits a parallel attitude which is a subsidiary, yet a highly title with a close human relationship. Culture and architecture are two closely interacting aspects which are drawing the borders of each other from time to time, hinting at quality and quantity, and evaluating such. Quite naturally, the structure which is in a deep relationship with mankind is in an exchange with all physical, social and economic qualities of the human. These qualities are fundamental determinants of the concept of culture as a human trait. The process of architecture which is usually defined as a sequence of eras that involve social movements, impulses and trends, sometimes kept moving ahead in the pursuit of individual leadership and styles. The concerns regarding the solution of space problems, setting up /designing venues and arranging the environment in line with the requirements brought up increasingly complex issues and stacks of solutions which follow such problems. It is this dynamic structure which forms the basis of the architectural problem to date. Starting with the housing and residential concepts, this study brings a critical view on the application samples and methods of the relationship between architecture and culture in terms of our country in particular while putting emphasis on the architectural venture of the

The BREN house transmission experiments provide an excellent set of measurements to validate the calculational procedures that will be used to derive house shielding estimates for the revised dosimetry of the survivors of the Hiroshima and Nagasaki A-bombs. The BREN experiments were performed in realistic full scale models of Japanese residences. Although the radiation spectra and relative intensities of neutrons and gamma rays incident on the houses from the HPRR and the 60 Co source are not appropriate for direct application to the A-bomb survivors, they cover the full energy range of importance. The codes and calculations required to compare with BREN experiments are the same as those needed for the A-bomb dosimetry. They consist of a two-dimensional discrete-ordinates calculation of the free field coupled to an adjoint Monte Carlo calculation in detailed house geometry. The agreement obtained between calculations and the experiments is excellent for neutrons and 60 Co gamma rays. Every house transmission calculation spanning simple to complex configurations and detector locations for the 60 Co and HPRR was within an acceptable margin of error. The gamma-ray TF calculations for the reactor source did not agree well with the experiments. Analysis of this discrepancy, however, strongly indicates that the problem probably does not reside in the calculational procedure but in the measurements themselves. In conclusion, it is believed that the excellent agreement of our calculations with the BREN experiments validates the calculational procedure which is planed to be applied o estimating the house shielding for survivors of the Hiroshima and Nagasaki A-bombs. Certainly, the calculations for Hiroshima and Nagasaki will involve modifications to the code used for the computations reported here, but to the extent that these modifications involve increased calculational complexity to treat more realistic materials and configurations, the benchmark established by these

The influence of facility and home pen design on the welfare of the laboratory-housed dog.

Scullion Hall, Laura E M; Robinson, Sally; Finch, John; Buchanan-Smith, Hannah M

We have an ethical and scientific obligation to Refine all aspects of the life of the laboratory-housed dog. Across industry there are many differences amongst facilities, home pen design and husbandry, as well as differences in features of the dogs such as strain, sex and scientific protocols. Understanding how these influence welfare, and hence scientific output is therefore critical. A significant proportion of dogs' lives are spent in the home pen and as such, the design can have a considerable impact on welfare. Although best practice guidelines exist, there is a paucity of empirical evidence to support the recommended Refinements and uptake varies across industry. In this study, we examine the effect of modern and traditional home pen design, overall facility design, husbandry, history of regulated procedures, strain and sex on welfare-indicating behaviours and mechanical pressure threshold. Six groups of dogs from two facilities (total n=46) were observed in the home pen and tested for mechanical pressure threshold. Dogs which were housed in a purpose-built modern facility or in a modern design home pen showed the fewest behavioural indicators of negative welfare (such as alert or pacing behaviours) and more indicators of positive welfare (such as resting) compared to those in a traditional home pen design or traditional facility. Welfare indicating behaviours did not vary consistently with strain, but male dogs showed more negative welfare indicating behaviours and had greater variation in these behaviours than females. Our findings showed more positive welfare indicating behaviours in dogs with higher mechanical pressure thresholds. We conclude that factors relating to the design of home pens and implementation of Refinements at the facility level have a significant positive impact on the welfare of laboratory-housed dogs, with a potential concomitant impact on scientific endpoints.

Full Text Available Bangladesh Traditional houses (B.T.H which are located in warm humid tropical climate represent a unique phenomenon with device capable to meet the comfort demand through environmental well adapted design.  Recently the traditional house and the contemporary design house (C.D.H for Bangladesh are examined by comparing the thermal performance within the same outdoor condition and the climatic region at the dense Dhaka city.  This comparison is based on field measurements of thermal performance of the traditional house and the contemporary design house within the same summer period. Quantitative method is used to measure the thermal performance. The field survey was conducted using two set of thermal data loggers were installed in both selected houses to record the air temperature and relative humidity of the outdoor and indoor spaces.  Data collection was carried out for the hot and wet month of summer period in June.  The research result concluded that the traditional houses of Bangladesh provided useful indicators of appropriate architectural design response to climate, particularly in the context of purely passive environmental control. However it is required to adapt a critical approach towards the modern contemporary architectural design strategy of deriving lesson from traditional houses to extend the period of indoor thermal environment inside the contemporary houses.

Modifying the home environments of older people as they age in place is a well-established health and social care intervention. Using design and construction methods to redress any imbalance caused by the ageing process or disability within the home environment, occupational therapists are seen as the experts in this field of practice. However, the process used by occupational therapists when modifying home environments has been criticised for being disorganised and not founded on theoretical principles and concepts underpinning the profession. To address this issue, research was conducted to develop a design and construction process protocol specifically for home modifications. A three-stage approach was taken for the analysis of qualitative data generated from an online survey, completed by 135 occupational therapists in the UK. Using both the existing occupational therapy intervention process model and the design and construction process protocol as the theoretical frameworks, a 4-phase, 9-subphase design and construction process protocol for home modifications was developed. Overall, the study is innovative in developing the first process protocol for home modifications, potentially providing occupational therapists with a systematic and effective approach to the design and delivery of home modification services for older and disabled people.

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

Full Text Available The research goals were to identify a spacial pattern in craftsmen house and to see its relevance to the social-cultural life of the craftsmen. The existence of domestic and economic activity in craftsmen house creates a spacial pattern with particular characteristics. Data were collected through direct observation, interviews, and visual documentation to record productive house, settlement condition, and sequences of pottery production. The in-depth interview focused on the use of time, space, and house modification in craftsmen house. House in the craftsmen settlement was growing gradually by adjusting to the inhabitant's needs. This research was included in qualitative research that described observation results and then analyzed spacial pattern formed in craftsmen house. Research results show that in this settlement beside the mixed, balanced, and separated type of productive house, there is also pottery collectors house type. The changes in the productive house are related to housing adaptation or house adjustment to accommodate production process. The settlement orientation is along the streets, but the existence of open space in the form of pottery kiln and hay storage become the main orientation for productive spaces inside the craftsmen house. Pottery kiln and hay storage have become open cultural space that characterizes the pottery craftsmen settlement. 

Savannah River Site reactor hardware design modification study

Fisher, J.E.

1990-03-01

A study was undertaken to assess the merits of proposed design modifications to the SRS reactors. The evaluation was based on the responses calculated by the RELAP5 systems code to double-ended guillotine break loss-of-coolant-accidents (DEGB LOCAs). The three concepts evaluated were (a) elevated plenum inlet piping with a guard vessel and clamshell enclosures, (b) closure of both rotovalves in the affected loop, and (c) closure of the pump suction valve in the affected loop. Each concept included a fast reactor shutdown (to 65% power in 100 ms) and a 2-s ac pump trip. For the elevated piping design, system recovery was predicted for breaks in the plenum inlet or pump suction piping; response to the pump discharge break location did not show improvement compared to the present system configuration. The rotovalve closure design improved system response to plenum inlet or pump discharge breaks; recovery was not predicted for pump suction breaks. The pump suction valve closure design demonstrated system recovery for all break locations downstream of the valve. A combination of features is recommended to ensure liquid inventory recovery for all break locations. The elevated piping design performance during pump discharge breaks would be improved with addition of a dc pump trip in the affected loop. Valve closure design performance for a break location in the short section of piping between the reactor concrete shield and the pump suction valve would benefit from the clamshell enclosing that section of piping. 12 refs., 10 figs., 2 tabs

Opportunities exist to reduce the incremental cost of R-2000 construction by using optimum value engineering (OVE) and integrated design (ID) techniques. OVE is a construction philosophy in which components and systems are designed to meet their intended purposes without excessive or unnecessary use of resources. This paper summarized a study that was designed to identify opportunities for reducing the costs of R-2000 houses while improving their performance. These included detailed energy and cost analysis of various OVE/ID options which were then applied to a sample of 18 representative new home designs from British Columbia, Manitoba, and New Brunswick. The paper described the OVE/ID measures studied, cost analysis, measure utilization and energy analysis. It also included a detailed discussion of individual OVE/ID measures. Examples of some of these measures were the elimination of floor system cross-bridging; support of non-load bearing partition walls; engineered wood beams; drywall clips at corners; and non-load bearing partition walls. It was concluded that significant opportunities exist to reduce the incremental cost of R-2000 houses through careful application of OVE and ID practices. 5 refs., 4 tabs., 1 fig.

The design for modifications to the CSB Cask Receiving pit guides was verified by the informal design verification (meeting) method on August 9, 2000. The invited list of attendees and the meeting attendance sheet are included in attachment 1. The design modifications that were reviewed are documented in ECN 654484 (attachment 2). The requirement that the design is to be verified against is to ''center the transportation cask sufficiently to allow installation of the guide funnel on the cask (± 0.25 inches or less)''. The alternatives considered are detailed in attachment 3. Alternative number 4, ''Modify The Pit Guides'', was determined to be the preferred alternative primarily due to considerations of simplicity, reliability, and low cost. Alternative 1, ''Rotate the impact Absorber 180 o '', was successfully performed but was considered a temporary fix that was not acceptable for a long term operational mode. The requirement to position the receiving crane accurately enough to lower the transportation cask into the pit with the redesigned guides was discussed and considered to be achievable without undue effort from the operator. The tolerance on the OD of the transfer cask was discussed (± 1/8 inch) relative to the clearance with the guides. As-built dimensions for the cask OD will be looked at to verify sufficient clearance exists with the maximum cask OD. The final design thickness of the shims under the guides will be based on the as-built cask OD dimensions and field measurements between the pit guides. The need for a ''plastic'' cover for the guides was discussed and deemed unnecessary. Thermal growth of the cask OD was calculated at 3-5 mils and considered insignificant. The possibility of reducing the OD of the guide funnel was reviewed but this was considered impractical due to the requirement for the MCO to miss the edge of the funnel in case of a MCO drop. One of the transportation casks have the lift trunions installed 3/8 inch off center. This is

Thermal design of a modern, air-conditioned, single-floor, solar-powered desert house

KAUST Repository

Serag-Eldin, M. A.

2011-12-01

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

Housing preferences of young adults in Indonesia: housing attributes and consequences

Science.gov (United States)

Farasa, N.; Kusuma, H. E.

2018-03-01

Nowadays, the housing demand of young adults in Indonesia is important issues for the sustainable development of the market. Facing differences of life phases, such as marriage, leaving home after graduation, and new job positioning, young adults become the main segment facing constant housing choice decisions in the housing market. In their particular phase of life, young adults have distinct preferences for housing attributes which bring a great influence on their lives in the future. Data was gathered from a survey questionnaire that was answered by 180 young adults in Indonesia, ranging from age 22-33 years. The findings suggest that the green area and view, location, simplicity, home design, and accessibility are the significant parts as housing attributes for young adults’ housing preferences in Indonesia. The effect of these attributes has many consequences such as security, personalization, mood/ambiance, maintenance, interaction, image, flexibility, environmental, economy, durability, convenience, comfort, and circulation. The biggest group of young adults who prefer comfort as their wanted consequences tend to have high preferences on housing attributes of the green area and view, and simplicity.

This book provides a comprehensive understanding on disaster resilient housing within the Vietnam context particularly and the developing world generally. The book has identified the root causes of housing vulnerability, restrictions to safe housing development, concepts of disaster resilient housing, key issues/factors implementers and building designers need to consider, and ways of achieving resilient housing outcomes in actual design projects. The design and development of disaster resilient housing has been framed into three main themes:  (i) community consultation, (ii) the role of built-environment professionals and (iii) design responses for resilience.   To achieve these themes, there is a variety of contextual and intervening conditions that need to be addressed and met to provide an enabling environment for promoting disaster resilient housing. These three themes are among the most arguable issues in recent debates and discussions, academically and practically, regarding disaster risk reduction ...

Water in Architecture and its Usage in Contemporary Houses Interior Design

Samaneh Sedighi

2017-10-01

Full Text Available As one of the most fundamental natural elements, water has had a great share in the formation and architecture of architectural buildings. This research examines the effect of water and its presence in contemporary houses. Architecture is not merely a tridimensional compound of forms in space, but a manifestation of a sense or a thought in it. According to Feng Shui, the building where we live in can be the cause of balance and health for human being. As a whole, anything around us has active and mobile energies; by designing a building in a way that positive energies can follow around easier, one can easier bring happiness for the dwellers. Feng Shui is based on the harmony among five elements of water, wind, soil, fire and metal. Because of its stream, water removes negative energies and revives and mobilizes positive ones thereby having a great impact on the current of energies. Considering the fact that contemporary houses are small in space, designer does not feel free in the usage of water in internal spaces, thus he/she should utilize patterns that resemble or associate the feeling of water in the living environment. Conceptual, functional and aesthetic basics of water have been examined first via library studies and note taking from various papers and books. Then, the three qualities would be analyzed in Iranian architecture, and the properties of past people will be examined to emphasize material, spiritual and psychological aspects of water. Then, I will assess the philosophical basics of Feng Shui in using water for interior spaces via a qualitative method and content analysis, usage of water based on Feng Shui in interior design and decoration of homes. Considering these concepts, natural possibilities of water in interior architecture and its limitations in interior space design would be assessed and recognized. Finally, some patterns would be presented to use water in interior spaces of contemporary apartments.

What housing features should inform the development of housing solutions for adults with neurological disability?: A systematic review of the literature.

Wright, Courtney J; Zeeman, Heidi; Kendall, Elizabeth; Whitty, Jennifer A

2017-07-01

Despite the recent emphasis in Australian political, academic, and legislative narratives to more actively promote real housing choice for people with high healthcare and support needs, there is a lack of understanding regarding the specific housing features that might constitute better housing solutions for this population. Inclusive housing provision in Australia rightly emphasises safety and accessibility issues but often fails to incorporate factors related to broader psychosocial elements of housing such as dwelling location, neighbourhood quality, and overall design. While the importance of these broader elements appears obvious, it is not yet clear what specific housing features relate to these elements and how they might contribute to housing solutions for people with high healthcare and support needs. For individuals with complex neurological conditions such as brain injury or cerebral palsy, who require maximum support on a daily basis yet want to live independently and away from a primary care hospital or health facility, a more detailed understanding of the housing features that might influence design and development is needed. Thus, in order to clarify the broader factors related to housing solutions for this population, a systematic review was conducted to identify and synthesise the current research evidence (post-2003) and guide future housing design and development opportunities. From the included studies (n=26), 198 unique housing features were identified. From the 198 features, 142 related to housing design (i.e., internal or external characteristics of the dwelling and its land), 12 related to the dwelling's location (i.e., its proximity to available resources), and 54 related to the nature of the surrounding neighbourhood (i.e., the physical, social, and economic conditions of the area). The findings of this review contribute significantly to the literature by reporting a broader scope of relevant housing features for people with neurological

Indoor air quality are important factors that need to be addressed because it can affect the health and comfort of occupants in it. Among the major sources of indoor air pollution are radon gas. Radiological risk due to radon gas due to its intake into the human body is the major cause of lung cancer. This study was conducted to determine the radon emanation rate that occurs naturally in the building materials and its contains in several kinds of house. Construction materials studied are sand, gravel, cement and bricks. Terrace houses, double storey terrace houses, flats and wooden houses were studied in radon emanation in various types of houses. Radon emanation rates in building materials in a variety of home and the home measured using Sun Nuclear radon monitor (model 1029) and radon gas concentrations are measured in units of Bq m -3 . From the results, granites have recorded the highest radon emissions that is 2.67 μBq kg -1 s -1 , followed by sand with 2.53 μBq kg -1 s -1 . The bricks emission rate were recorded was 2.47 μBq kg -1 s -1 , while Cement recorded the lowest with only 1.46 μBq kg -1 s -1 . In study of radon in a variety of home, the results showed that the single storey terrace houses recorded the highest reading of 25.67 ± 4.96 Bq m -3 . First level Double storey terrace houses recorded 23.24 ± 3.72 Bq m -3 compared with a second level of two-storey terrace house which recorded emission rate of 16.43 ± 2.53 Bq m -3 . Flats were recorded the second lowest with only 13.07 ± 2.38 Bq m -3 . House that recorded the lowest reading was wooden houses that recorded 9.53 ± 1.96 Bq m -3 . (author)

Levels of radon and its short-lived airborne progeny are being measured in a year-long study of 70 houses in four states in the Tennessee Valley. Various methods were used to solicit volunteers with differing degrees of success. Criteria for selection of houses in the study included presence of a lower level with cement floor and one or more block walls in contact with the soil, absence of obvious indications of technologically enhanced sources of radium, and proximity to one of four cities, (Knoxville, Chattanooga, Birmingham, or Florence). By design, most houses in the study are in the same neighborhood as at least one other house in the study. Houses range in age from newly constructed to about 40 years old. Most of the houses have more than 2000 square feet of finished floor space. The lower level encompasses a garage in most cases. More complete information pertaining to house characteristics will be gathered in the course of the study. Measurements are being made to obtain information on both location- and season-dependent variation of radon and radon progeny. Simultaneous measurements are made quarterly on both upper and lower levels of each house. Grab samples of air are collected and analyzed for radon using a modified Lucas cell technique. Short-term (10-minute) samples of airborne particulate material are collected and analyzed for radon progeny. One-week integrated measurements of working levels are made once each quarter using modified thermoluminescent dosimeters. Both three- and twelve-month integrated measurements of radon using track-etch monitors are being made. 19 references, 1 figures

2005-04-01

Full Text Available Abstract Background This article discusses the study design and methods used to contextualize and assess the social capital of seniors living in congregate housing residences in Calgary, Alberta. The project is being funded as a pilot project under the Institute of Aging, Canadian Institutes for Health Research. Design/Methods Working with seniors living in 5 congregate housing residencies in Calgary, the project uses a mixed method approach to develop grounded measures of the social capital of seniors. The project integrates both qualitative and quantitative methods in a 3-phase research design: 1 qualitative, 2 quantitative, and 3 qualitative. Phase 1 uses gender-specific focus groups; phase 2 involves the administration of individual surveys that include a social network module; and phase 3 uses anamolous-case interviews. Not only does the study design allow us to develop grounded measures of social capital but it also permits us to test how well the three methods work separately, and how well they fit together to achieve project goals. This article describes the selection of the study population, the multiple methods used in the research and a brief discussion of our conceptualization and measurement of social capital.

Passive houses in Sweden. Experiences from design and construction phase

Energy Technology Data Exchange (ETDEWEB)

Jansson, Ulla

2008-07-01

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

Traditional Values and their Adaptation in Social Housing Design: Towards a New Typology and Establishment of ‘Air House’ Standard in Malaysia

Full Text Available Large migration from rural areas to urban areas like Kuala Lumpur has led to some implications for economic, social and cultural development. This high population has placed enormous demand on the existing housing stocks, especially for low-income groups.  However, some issues arise, one of which is overheated indoor air temperature. This problem contributes to the high-energy usage that forces huge sums of money to be spent on cooling the house by using mechanical equipment. Therefore, this study focuses on thermal comfort in social housing, and incorporates traditional values into its design to achieve a certain measurement of natural ventilation in a house. From the study, the carbon emission and energy consumption for an air-conditioned house is 67%, 66% higher than a naturally ventilated house. Therefore, this research has come up with a new typology design, which has a large exposed wall area and full-length openings on the opposite walls to increase cross ventilation. At the end of this research, the measurement of thermal comfort for a naturally ventilated building called ‘Air House’ has been identified.

2014-11-01

The directions of development of the construction market are not only related to the need to own one's own home but also to increasing functional and economic requirements and conditions of sustainable development. The perception and understanding of prefabrication in housing construction are undoubtedly starting to change. Sustainable construction criteria may constitute a significant turning point and support for the development of new prefabricated housing construction technologies. Entrepreneurs are slowly perceiving an opportunity for the development of prefabrication in the construction market. The implementation and popularisation of ready-made homes will undoubtedly constitute a favourable change in the Polish construction market; however, this will require a modification of habits. This article presents an historical analysis of the development of the prefabricated housing construction market as well as an attempt to answer questions concerning the future of prefabrication in housing construction in Poland based on the conducted studies.

Full Text Available Previous research suggests that reducing sedentary screen behaviors may be a strategy for preventing and treating obesity in children. This systematic review describes strategies used in interventions designed to either solely target sedentary screen behaviors or multiple health behaviors, including sedentary screen behaviors. Eighteen studies were included in this paper; eight targeting sedentary screen behaviors only, and ten targeting multiple health behaviors. All studies used behavior modification strategies for reducing sedentary screen behaviors in children (aged 1–12 years. Nine studies only used behavior modification strategies, and nine studies supplemented behavior modification strategies with an electronic device to enhance sedentary screen behaviors reductions. Many interventions (50% significantly reduced sedentary screen behaviors; however the magnitude of the significant reductions varied greatly (−0.44 to −3.1 h/day and may have been influenced by the primary focus of the intervention, number of behavior modification strategies used, and other tools used to limit sedentary screen behaviors.

Evaluation of materials and design modifications for aircraft brakes

Science.gov (United States)

Ho, T. L.; Kennedy, F. E.; Peterson, M. B.

1975-01-01

A test program is described which was carried out to evaluate several proposed design modifications and several high-temperature friction materials for use in aircraft disk brakes. The evaluation program was carried out on a specially built test apparatus utilizing a disk brake and wheel half from a small het aircraft. The apparatus enabled control of brake pressure, velocity, and braking time. Tests were run under both constant and variable velocity conditions and covered a kinetic energy range similar to that encountered in aircraft brake service. The results of the design evaluation program showed that some improvement in brake performance can be realized by making design changes in the components of the brake containing friction material. The materials evaluation showed that two friction materials show potential for use in aircraft disk brakes. One of the materials is a nickel-based sintered composite, while the other is a molybdenum-based material. Both materials show much lower wear rates than conventional copper-based materials and are better able to withstand the high temperatures encountered during braking. Additional materials improvement is necessary since both materials show a significant negative slope of the friction-velocity curve at low velocities.

Designing Life after the Storm: Improvisations in Post-Disaster Housing Reconstruction as Socio-Moral Practice

Directory of Open Access Journals (Sweden)

Pamela Gloria Cajilig

2017-11-01

Full Text Available If there is any endeavor so demanding of human creativity, it is the remaking of lives and property after disaster. However, post-disaster recovery is considered the greatest failure in disaster management, and within this field, post-disaster housing reconstruction is the most insufficiently investigated practice. Furthermore, studies of disaster management attribute failure to top-down and technocratic approaches that often overlook the agency, capacities, and moral priorities of those directly affected. In contrast, this paper attends to those displaced by disaster as creative and moral agents who manage to carry on with life despite their socio-economic and political vulnerabilities by drawing from theory in anthropology, disaster studies, and cognitive psychology. Through examining how inhabitants of a post-Typhoon Yolanda (Haiyan reset­tlement site transform their housing to negotiate multiple and vague rules and regulations, I entangle myself with literature that assumes that the creativity of design lies in the capacity of individuals to improvise according to their values and in response to those of others, within a world that is continually unfolding. I also assume that improvisation is contingent upon processes of cognitive innovation in which social relations operate as indispensable intellectual resources for grasping and mobilizing knowledge that would give inhabitants of resettlement housing the best possible chance of attaining their hopes, dreams, and ambitions. Consequently, I propose that viewing creativity as an improvisational process highlights the agentic potential of design in even the bleakest and most quotidian of settings. My own hope is to extend the possibilities for correspondence between built environment practitioners and those who, because of their subaltern positionalities, tend to be overlooked by the field of post-disaster housing reconstruction and yet must live through the consequences of its practice.

Pre-Design of Transitional Rural Housing for Syria with Recycled Rubble from Destroyed Buildings

Morishita, Naomi; Haj Ismail, Salah; Cetin, Rukiye

2017-10-01

The scale of destruction caused by seven years of on-going war in Syria has caused mass migration of the Syrian people within and outside of Syria. The situation calls for a means to provide the internally displaced persons (IDPs) within Syria with humane post-war affordable housing that can be quickly and easily built with few resources. Fossil fuel resources are not only scarce because of the war, but are also being used as a valuable commodity to finance the war economy, and thus, housing should minimize consumption of energy for heating and cooling because of the fossil fuel scarcity while providing high thermal comfort to the inhabitants. The housing parameters for the proposed solution are to integrate as much of the local building materials in the Aleppo region as possible using existing regional building traditions. Imported products such as building materials, machinery, equipment, as well as foreign labour and knowhow are to be kept to a minimum while incorporating recycled rubble from destroyed buildings. A comparative study of current disaster relief housing illustrates the appropriateness of each design solution in relation to the above-proposed housing parameters. A detailed analysis of the physical properties of an existing case study building in Dabiq, a town 40 km northeast of Aleppo, outlines the strengths and weaknesses of the building tradition to determine which aspects of the construction may be improved for better thermal comfort and resistance against earthquakes. The simulation results from WUFI Plus show the building behaviour of the case study house. This paper offers a concept for transitional single-family housing for IDPs based upon the adobe tradition in the rural areas of Aleppo. Reducing the heating and cooling loads can also drastically reduce fossil fuel requirements during the construction and operation phases of the single-family homes while maintaining a high level of indoor thermal comfort.

Wood moisture monitoring during log house thermal insulation mounting

Directory of Open Access Journals (Sweden)

Pavla Kotásková

2011-01-01

Full Text Available The current designs of thermal insulation for buildings concentrate on the achievement of the required heat transmission coefficient. However, another factor that cannot be neglected is the assessment of the possible water vapour condensation inside the construction. The aim of the study was to find out whether the designed modification of the cladding structure of an existing log house will or will not lead to a risk of possible water vapour condensation in the walls after an additional thermal insulation mounting. The condensation could result in the increase in moisture of the walls and consequently the constructional timber, which would lead to the reduction of the timber construction strength, wood degradation by biotic factors – wood-destroying insects, mildew or wood-destroying fungi. The main task was to compare the theoretically established values of moisture of the constructional timber with the values measured inside the construction using a specific example of a thermal insulated log house. Three versions of thermal insulation were explored to find the solution of a log house reconstruction which would be the optimum for living purposes. Two versions deal with the cladding structure with the insulation from the interior, the third version deals with an external insulation.In a calculation model the results can be affected to a great degree by input values (boundary conditions. This especially concerns the factor of vapour barrier diffusion resistance, which is entered in accordance with the producer’s specifications; however, its real value can be lower as it depends on the perfectness and correctness of the technological procedure. That is why the study also includes thermal technical calculations of all designed insulation versions in the most unfavourable situation, which includes the degradation of the vapour barrier down to 10% efficiency, i.e. the reduction of the diffusion resistance factor to 10% of the original value

Aqida, S. N.; Brabazon, D.; Naher, S.

2011-01-01

This paper presents a design of experiment (DOE) for laser surface modification process of AISI H13 tool steel in achieving the maximum hardness and minimum surface roughness at a range of modified layer depth. A Rofin DC-015 diffusion-cooled CO2 slab laser was used to process AISI H13 tool steel samples. Samples of 10 mm diameter were sectioned to 100 mm length in order to process a predefined circumferential area. The parameters selected for examination were laser peak power, overlap percentage and pulse repetition frequency (PRF). The response surface method with Box-Behnken design approach in Design Expert 7 software was used to design the H13 laser surface modification process. Metallographic study and image analysis were done to measure the modified layer depth. The modified surface roughness was measured using two-dimensional surface profilometer. The correlation of the three laser processing parameters and the modified surface properties was specified by plotting three-dimensional graph. The hardness properties were tested at 981 mN force. From metallographic study, the laser modified surface depth was between 37 μm and 150 μm. The average surface roughness recorded from the 2D profilometry was at a minimum value of 1.8 μm. The maximum hardness achieved was between 728 and 905 HV0.1. These findings are significant to modern development of hard coatings for wear resistant applications.

ANALYSIS OF CLIMATIC AND SOCIAL PERFORMANCES OF LOW COST TERRACE HOUSING (LCTH: INTRODUCING THE AFFORDABLE QUALITY HOUSING (AQH CONCEPT IN MALAYSIA

Directory of Open Access Journals (Sweden)

Noor Hanita Abdul Majid

2009-03-01

Full Text Available Low cost terrace housing (LCTH is the most common form and popular typology of public housing in Malaysia. The provision of the houses is deemed to be the most suitable to fulfil the needs to house low income families, and also as an alternative to high rise low cost housing. Since the implementation of these housing types, development on the layout and sizes of the house has taken place to provide for better living conditions. Literature review on the current LCTH suggested that there are deficiencies in fulfilling the requirements to provide quality and affordable housing for the low income families. This paper presents the scenario of the LCTH design based on secondary findings by researchers on housing in Malaysia. The secondary data provided the grounds for the proposal of affordable and quality housing (AQH to handle the problems that occurred at the LCTH. Both social and climatic considerations are included in the AQH, addressing issues on privacy, segregation of genders and community interaction; along with thermal comfort and natural ventilation. Decisions on the AQH are carefully extracted from a comparison analysis in the view to improve the current conditions. In order to verify some of the decisions on climatic design strategies, simulation results are presented. The results indicated that the design decisions have managed to improve on the natural ventilation conditions at the low cost houses. With reservations on the social conditions that are yet to be tested at the actual houses, the AQH has proven to be a step forward towards the provision of a better living environment.

Models for Experimental High Density Housing

Bradecki, Tomasz; Swoboda, Julia; Nowak, Katarzyna; Dziechciarz, Klaudia

2017-10-01

The article presents the effects of research on models of high density housing. The authors present urban projects for experimental high density housing estates. The design was based on research performed on 38 examples of similar housing in Poland that have been built after 2003. Some of the case studies show extreme density and that inspired the researchers to test individual virtual solutions that would answer the question: How far can we push the limits? The experimental housing projects show strengths and weaknesses of design driven only by such indexes as FAR (floor attenuation ratio - housing density) and DPH (dwellings per hectare). Although such projects are implemented, the authors believe that there are reasons for limits since high index values may be in contradiction to the optimum character of housing environment. Virtual models on virtual plots presented by the authors were oriented toward maximising the DPH index and DAI (dwellings area index) which is very often the main driver for developers. The authors also raise the question of sustainability of such solutions. The research was carried out in the URBAN model research group (Gliwice, Poland) that consists of academic researchers and architecture students. The models reflect architectural and urban regulations that are valid in Poland. Conclusions might be helpful for urban planners, urban designers, developers, architects and architecture students.

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

Science.gov (United States)

Barber, Daniel A

2014-01-01

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

1976-01-01

Short beam usage times were encountered using a 60 keV electron beam welder. These short times were the direct result of a buildup of a reaction product (WO 2 . 90 ) that occurred on graphite washers which housed the tungsten emitter plate. While it was not possible to prevent the reaction product, its growth rate was sufficiently altered by changing graphite materials and minor design changes of the washers. With these modifications beam usage times increased from an original 40 min to approximately 675 min

IBACOS used several modeling programs and calculation methods to complete the final design package along with Brookfield's architect KGA Studio. This design package included upgrades to the thermal enclosure, basement insulation, windows, and heating, ventilation, and air conditioning. Short-term performance testing in the Passive House was done during construction and after construction. Testing with a blower door indicated that whole-building air leakage to the outside was 324 CFM and 0.60 ACH50. The other two test homes had little short-term testing done post-construction by the local energy rater. IBACOS then monitored the energy consumption and whole-house comfort conditions of that occupied Passive House after one year of operation and compared the monitoring results to those for two other occupied test houses in the same area with similar square footage but slightly different floor plans. IBACOS also assisted the builder, Brookfield Homes, in researching design scenarios for Zero Energy Ready Home and ENERGY STAR acceptance levels. IBACOS also assisted Brookfield in conceptualizing product for Denver's Brighton Heights area. Brookfield was considering building to Zero Energy Ready Home standards in that location. IBACOS provided strategies that Brookfield may draw from in the event the builder chooses to pursue a Zero Energy Ready Home plan for that market.

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

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

Directory of Open Access Journals (Sweden)

Margaret Ward

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

RETHINKING HOUSING EDUCATION IN ARCHITECTURE SCHOOLS

Directory of Open Access Journals (Sweden)

Avi Friedman

2010-07-01

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 CONCEPT OF LOCAL-SMART-HOUSING: TOWARDS SOCIO-CULTURAL SUSTAINABILITY OF VERNACULAR SETTLEMENTS

Directory of Open Access Journals (Sweden)

AmirHosein GhaffarianHoseini

2011-07-01

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

PSA effect analysis of a design modification of the auxiliary feedwater system for a Westinghouse type plant

International Nuclear Information System (INIS)

Bae, Yeon Kyoung; Lee, Eun Chan

2012-01-01

The auxiliary feedwater system is an important system used to mitigate most accidents considered in probabilistic safety assessment (PSA). The reference plant has produced electric power for about thirty years. Due to age related deterioration and lack of parts, a turbine driven auxiliary feedwater pump (TD AFWP), some valves, and piping of the auxiliary feedwater system should be replaced. This change includes relocation of some valves, installation of valves for maintenance of the steam generator, and a new cross tie line. According to the design change, the Final Safety Analysis Report (FSAR) has been revised. Therefore, this design modification affects the PSA. It is thus necessary to assess the improvement of plant safety. In this paper, the impact of the design change of the auxiliary feedwater system on the PSA is assessed. The results demonstrate that this modification considering the plant safety decreased the total CDF

The off-grid technologies and tiny house movement have experimented an unprecedented growth in recent years. Putting both sides together, we are trying to achieve an economic and environmental friendly solution to the higher cost of residential properties. This solution is the construction of off-grid tiny houses. This article presents a design for a small modular off-grid house made by pine timber. A numerical analysis of the proposed tiny house was performed to ensure its structural stability. The results were compared with the suggested serviceability limit state criteria, which are contended in the Australia Guidelines Standards making this design reliable for construction.

Savannah River Site reactor hardware design modification study

International Nuclear Information System (INIS)

Fisher, J.E.

1990-01-01

A study was undertaken to assess the merits of proposed design modifications to the Savannah River Site (SRS) reactors. The evaluation was based on the responses calculated by the RELAP5 systems code to double-ended guillotine break loss-of-coolant-accidents (DEGB LOCAs). The three concepts evaluated were (a) elevated plenum inlet piping with a guard vessel and clamshell enclosures, (b) closure of both rotovalves in the affected loop, and (c) closure of the pump suction valve in the affected loop. Each concept included a fast reactor shutdown (to 65% power in 100 ms) and a 2-s ac pump trip. System recovery potential was evaluated for break locations at the pump suction, the pump discharge, and the plenum inlet. The code version used was RELAP5/MOD2.5 version 3d3, a preliminary version of RELAP5/MOD3. The model was a three-dimensional representation of the K-Reactor water plenum and moderator tank. It included explicit representations of all six loops, which were based on the configuration of L-Reactor. A combination of features is recommended to ensure liquid inventory recovery for all break locations. Valve closure design performance for a break location in the short section of piping between the reactor concrete shield and the pump suction valve would benefit from the clamshell enclosing that section of piping. 7 refs., 10 figs., 2 tabs

The conceptual design for the modification of HL-2A tokamak

International Nuclear Information System (INIS)

Dequan Liu

2006-01-01

The medium-sized tokamak HL-2A, based on the former ASDEX's main components has approached its rating operational parameters with I p = 450 kA and B T =2.8 T so far. The HL-2A was originally designed to operate under an axisymmetrical double-null configuration by two triplets of shaping coils located in the vacuum vessel. Because the shaping coils were set very close to the plasma column, the nulls are normally fixed and the plasma has a nearly circular cross-section. It is difficult to increase the parameters further and obtain a preferable plasma shape with certain values of triangularity and elongation. Due to the defects on upper shaping coils' electrical insulation, the HL-2A is presently just operated with lower single null divertor configuration. Additionally, the experiment has to occasionally terminate due to incidental damages of the weak parts. With the experimental progress on HL-2A, the plasma stored energy and auxiliary heating power is being increased, a more efficient, compact and tight divertor is needed. Based on present status of HL-2A tokamak and for satisfying the requirements of the experiment, the modification of HL-2A tokamak device will be carried out. The modification design of HL-2A intents to obtain optimized plasma parameters, e.g., aspect ratio, I p , b, plasma volume, certain plasma shaping with preferable elongation and triangularity, a stable vacuum vessel easy to be maintained and an advanced divertor. The primary consideration of the modification is to take all of the shaping coils out of the vessel to enlarge the plasma volume. The elongated and triangular cross section with double null of plasma is to be obtained by composite distribution of eight sets of poloidal coils. Because all poloidal coils will be located between the TF coil and the vessel, the vacuum vessel will be remade with a smaller size to make rooms for the poloidal coil system. With an optimized operation mode, the volt-second of the plasma may be increased a

Strategies for Living in Houses

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

New mediterranean elements in contemporary housing. The case of Barcelona

Vincenzo Paolo Bagnato

2012-10-01

Full Text Available In the face of increasing and differentiating the low-cost housing demand and the trend of establishing new paradigms in the contemporary housing design, the architectural investigation has replaced into its disciplinary statement the topic of housing as central question in research and design experimentation. The city of Barcelona has codified in the last years innovative modalities of public management in social housing, offering interesting points of reflection on the idea of housing and of Mediterranean quality in urban, architectural and constructive terms. The paper proposes a key to the reading on the recent experiences of social housing in Barcelona illustrating the different forms through which architecture interprets the relationship between housing and public space, between innovation and constructive tradition.

INTEGRATED DESIGN AND ENGINEERING USING BUILDING INFORMATION MODELLING: A PILOT PROJECT OF SMALL-SCALE HOUSING DEVELOPMENT IN THE NETHERLANDS

Directory of Open Access Journals (Sweden)

Rizal Sebastian

2010-11-01

Full Text Available During the design phase, decisions are made that affect, on average, 70% of the life-cycle cost of a building. Therefore, collaborative design relying on multidisciplinary knowledge of the building life cycle is essential. Building information modelling (BIM makes it possible to integrate knowledge from various project participants that traditionally work in different phases of the building process. BIM has been applied in a number of large-scale projects in the industrial real estate and infrastructure sectors in different countries, including The Netherlands. The projects in the housing sector, however, are predominantly small scale and carried out by small and medium enterprises (SMEs. These SMEs are looking for practical and affordable BIM solutions for housing projects. This article reports a pilot project of small-scale housing development using BIM in the province of Zeeland, The Netherlands. The conceptual knowledge derived from European and national research projects is disseminated to the SMEs through a series of experimental working sessions. Action learning protocols within a pilot project are developed to ensure direct impacts in terms of cost reduction and quality improvement. The project shows that BIM can be applied without radical changes to the SMEs' information and communication technology systems or to their business organizations.

Procedure for developing biological input for the design, location, or modification of water-intake structures

Energy Technology Data Exchange (ETDEWEB)

Neitzel, D.A.; McKenzie, D.H.

1981-12-01

To minimize adverse impact on aquatic ecosystems resulting from the operation of water intake structures, design engineers must have relevant information on the behavior, physiology and ecology of local fish and shellfish. Identification of stimulus/response relationships and the environmental factors that influence them is the first step in incorporating biological information in the design, location or modification of water intake structures. A procedure is presented in this document for providing biological input to engineers who are designing, locating or modifying a water intake structure. The authors discuss sources of stimuli at water intakes, historical approaches in assessing potential/actual impact and review biological information needed for intake design.

The challenge of the global management of plant design modifications. example of the new EJ system at Vandellos NPP

International Nuclear Information System (INIS)

Ortega, Fernando; Valdivia, Carlos; Fernandez Illobre, Luis; Trueba, Pedro

2010-01-01

One of the most challenging areas in the operation of nuclear power plants (NPP) is related to the management of plant design modifications. Plant modifications can be made to improve reliability, facilitate operation, improve safety or get better results. In any of these situations, plant modifications imply many different activities that have to be done in a coordinated manner. NUREG-0711 (Human Factors Engineering Program Review Model) shows a global approach to manage most of these activities. Although this approach is mainly focused on the design and construction of new plants, it can also be applied to plant modification management. Successful global management will require performing every activity in a specific order, taking advantage of the output coming from some tasks as input for others and finalizing every task when necessary. This will provide the best results in terms of quality, time required for implementation, safe and reliable operation and maintenance, and cost. Tecnatom is involved in most of the activities related to the operational areas and has applied a global approach to get advantages in terms of quality and cost, which is outlined in this paper. As an example of this approach, the Vandellos NPP experience is shown in this presentation. Vandellos NPP carried out an important design modification that consists of replacing an old essential service water system with a new one. This was a three-year project that implied the construction of new reservoirs, new buildings, the implementation of new equipment, and new panels in the main control room. This paper shows the way in which all of these activities were performed. (authors)

Two industrial scale, ROBO type Co 60 gamma irradiation facilities have recently been put into operation in Syria and Peru, and the dosimetry commissioning of both plants have been carried out to determine dose distribution with products and to calculate plant parameters such as efficiency, dose uniformity ratio and throughput. There are some design modifications between the two plants in connection with the location of the carriers with respect to the source plaque and also to each other. The effect of these construction modifications on the plant parameters is discussed in the analysis of the dose distribution data measured in the carriers with depth and height among the four irradiation rows on both sides of the source plaque. The plant parameters were also calculated and measured results were compared to each other. (author)

Electric and mechanical basic parameters to elaborate a process for a technical verification of safety related design modifications

International Nuclear Information System (INIS)

Lamuno Fernandez, Mercedes; La Roca Mallofre, GISEL; Bano Azcon, Alberto

2010-01-01

This paper presents a systematic process to check a design in order to achieve all the requirements that regulations demand. Nuclear engineers must verify that a design is done according to the safety requirements, and this paper presents how we have elaborated a process to improve the technical project verification. For a faster, better and easier verification process, here we summarize how to select the electric and mechanical basic parameters, which ensure the correct project verification of safety related design modifications. This process considers different aspects, which guarantee that the design preserves the availability, reliability and functional capability of the Structures, Systems and Components needed to operate the Nuclear Power Station with security. Electric and mechanical reference parameters are identified and discussed as well as others related ones, which are critical to safety. The implementation procedure to develop tasks performed in any company that has a quality plan is a requirement. On the engineering business, it is important not to use the personal criteria to do a technical analysis of a project; although, many times it is the checker's criteria and knowledge responsibility to ensure the correct development of a design modification. Then, the checker capabilities are the basis of the modification verification. This kind of procedure's development is not easy, because in an engineering project with important technical contents, there are multiple scenarios, but lots of them have a common basis. If we can identify the technical common basis of these projects, we will make good project verification but there are many difficulties we can encounter along this process. (authors)

Growing community : rooftop gardens for affordable housing

Energy Technology Data Exchange (ETDEWEB)

Weeks, K.N. [California Univ., Berkeley, CA (United States)

2007-07-01

This paper reviewed the processes used in recently designed affordable housing roof garden projects in California, Montana and Georgia. Gardens create a sense of community through shared space and social interactions. As such, roof gardens can give residents of affordable housing the opportunity to experience the community-fostering benefits of gardening, with the added advantages of potentially lower energy bills and wastewater fees. The factors that should be considered in planning, design, construction and maintenance of roof gardens for affordable housing were also outlined. As places of refuge, gardens help people relax and promote healing, which is particularly important for physical, emotional, social and economic well-being. For the many residents of affordable housing who earn less than 50 per cent of the area median income, gardens offer a venue for establishing relationships with neighbours, many of whom they might otherwise never meet. They also offer a means to improved nutrition and food security, education and positive recreation for youth, and better aesthetic surroundings. While motivations for choosing green roofs varied widely across the projects, affordability was linked to 3 main areas, namely saving costs in design, construction and operations; getting the roof to generate funding; and, improving the quality of life in affordable housing. 17 refs., 12 figs.

A Comparative Study of Entrance in Traditional and Contemporary Houses of Iran

Directory of Open Access Journals (Sweden)

Ramin Dehbandi

2017-12-01

Full Text Available In contemporary houses in Iran, because of changes in the methods of designing and building houses, importance of entrance reduced to such level that now in contemporary houses entrance is just a door. Entrance correlates indoor safe space of house and outdoors. It`s importance lays in controlling entry, exit, territory and hierarchy. Since house owners were satisfied with traditional form of entrance, it is a good idea to learn from them in designing new entrances. The purpose of this research is to find a way for designing appropriate entrances for Iranian contemporary houses. To do this at first 40 traditional houses and 40 contemporary houses in Isfahan and Kashan were selected. These two cities are from margin of desert and the origin of traditional houses of Iran. Analysis showed that blockage of visual and phonic relation, creating a space between outdoor public space and indoor private space, creating access patterns to internal spaces and traits that separate in and out were the most significant properties of traditional entrances. All these traits are ignored in contemporary entrances. Suggestions made for design include creating public meeting space in yard and creating a separate entrance space for each house in apartments.

A literature review on the improvement strategies of passive design for the roofing system of the modern house in a hot and humid climate region

Directory of Open Access Journals (Sweden)

Qairuniza Roslan

2016-03-01

Full Text Available Increase of indoor temperature compared with outdoor temperature is a major concern in modern house design. Occupants suffer from this uncomfortable condition because of overheating indoor temperature. Poor passive design causes heat to be trapped, which influences the rise in indoor temperature. The upper part, which covers the area of the roof, is the most critical part of the house that is exposed to heat caused by high solar radiation and high emissivity levels. During daytime, the roof accumulates heat, which increases the indoor temperature and affects the comfort level of the occupants. To maintain the indoor temperature within the comfort level, most house designs usually depend on mechanical means by using fans or air conditioning systems. The dependence on a mechanical ventilation system could lead to additional costs for its installation, operation, and maintenance. Thus, this study concentrates on reviews on passive design and suggests recommendations for future developments. New proposals or strategies are proposed to improve the current passive design through ventilated and cool roof systems. It is possible to achieve the comfort level inside a house throughout the day by reducing the transmitted heat into the indoor environment and eliminating the internal hot air. These recommendations could become attractive strategies in providing a comfortable indoor temperature to the occupants as well as in minimizing energy consumption.

Solar Living House Final Technical Report

Energy Technology Data Exchange (ETDEWEB)

Walters, Bradley [Univ. of Florida, Gainesville, FL (United States)

2017-03-09

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

Epigenetic modifications can respond rapidly to environmental changes and can shape phenotypic variation in accordance with environmental stimuli. One of the most studied epigenetic marks is DNA methylation. In the present study, we used the methylation-sensitive amplified polymorphism (MSAP) technique to investigate the natural variation in DNA methylation within and among subspecies of the house sparrow, Passer domesticus We focused on five subspecies from the Middle East because they show great variation in many ecological traits and because this region is the probable origin for the house sparrow's commensal relationship with humans. We analysed house sparrows from Spain as an outgroup. The level of variation in DNA methylation was similar among the five house sparrow subspecies from the Middle East despite high phenotypic and environmental variation, but the non-commensal subspecies was differentiated from the other four (commensal) Middle Eastern subspecies. Further, the European subspecies was differentiated from all other subspecies in DNA methylation. Our results indicate that variation in DNA methylation does not strictly follow subspecies designations. We detected a correlation between methylation level and some morphological traits, such as standardized bill length, and we suggest that part of the high morphological variation in the native populations of the house sparrow is influenced by differentially methylated regions in specific loci throughout the genome. We also detected 10 differentially methylated loci among subspecies and three loci that differentiated between commensal or non-commensal status. Therefore, the MSAP technique detected larger scale differences among the European and non-commensal subspecies, but did not detect finer scale differences among the other Middle Eastern subspecies. © 2017.

Creating dune landscapes for nature and housing - how to assess the designs?

Science.gov (United States)

van den Ancker, J.; Jungerius, P. D.; Hartman, J.

2012-04-01

Over the last decades landscape and nature organisations in The Netherlands initiated discussions about safeguarding characteristic historical landscapes, as well as improving nature and landscape quality. In these discussions they were supported by Dutch government agencies and newspapers. As a consequence, architects, landscape architects and building firms in the Netherlands try to upgrade the quality of houses and build-up areas by creating special landscape settings. Dunes are one of the landscapes that appeal to the designers, and several projects make use of dunes to create a quality living environment. Also nature manager construct dunes in what is called 'new nature'. This contribution evaluates several projects creating dune landscapes. Criteria for the evaluation are: - the subsequent geomorphology, - the materials used for construction, - the resulting internal structure, - the soil profile, - the relationship with the vegetation, - the historical integrity of the location. These examples indicate that engaging earth-scientific knowhow would substantially improve the authenticity of the designs.

Project to design and develop an energy-related program: For public housing residents and renters: Volume 1, Final report

Energy Technology Data Exchange (ETDEWEB)

1988-05-01

This demonstration project was undertaken as a result of an unsolicited proposal submitted by THE ASSIGNMENT GROUP (TAG) to the Office of Minority Economic Impact, Department of Energy (DOE). The problem to which the proposal responded was how to minimize the costs associated with public housing tenants in standard public housing as well as under homeownership transfers. A related problem was how to graduate the tenants to another level of responsibility and self-sufficiency through resident business developments and training in energy-related fields. The size and gravity of the problem necessitated a purpose or aim that had nationwide application, yet lent itself to a microscopic look. Consequently, the goal that emanated was the design and development of an energy-related demonstration program that educates public housing residents, facilitates indigenous business development where appropriate, and trains residents to provide needed services.

Shading Performance on Terraced House Facades in Putrajaya, Malaysia

Hassan Ahmad Sanusi

2015-01-01

Full Text Available This study evaluates shading performance on house facades of selected three terraced houses in Putrajaya, Malaysia as the case studies. Terraced house type is selected for the case study because it is the most popular house type built in this country to house an increase of the urban population. Its total number built in urban area increases from 27% of the total dwellings in 1980 to 40% in 1990, and to slightly more than 60 per cent in 2000. The Case Study A, B, and C are atypical style of terraced house facade designs built in Putrajaya. These postmodern designs exhibit a range of complex geometric elements blending of colonial and traditional elements with colorful styles on the house facade. In this study, the time at which the sun path perpendicular to the house facade will be used to gain the results of shading performances when the house facades have their maximum exposure to the direct sunlight. The house facade was divided into two main parts which are opaque and glazing surface elements. The amount of shading area on the opaque and glazing surface was simulated using the SunTool program. In conclusion, the Case Study C had the highest average percentage of the shading area, which is 64.43%, followed by the Case Study A 60.41% and Case Study B 56.29%. These results showed that the facade designs had excellent horizontal shading elements with roof overhangs for high angle sunlight but they had weak vertical shading elements due to a lack of considerations of louvered elements to block low angle sunlight.

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

Research-based standards for accessible housing

Helle, Tina; Iwarsson, Susanne; Brandt, Åse

Since standards for accessible housing seldom are manifestly based on research and vary cross nationally, it is important to examine if there exists any scientific evidence, supporting these standards. Thus, one aim of this study was to review the literature in search of such scientific evidence...... data on older citizens and their housing environment in Sweden, Germany and Latvia (n=1150), collected with the Housing Enabler instrument. Applying statistical simulation we explored how different national standards for housing design influenced the prevalence of common environmental barriers. Kaplan...... by the database search (n= 2,577), resulting in the inclusion of one publication. Contacts to leading researchers in the field identified five publications. The hand search of 22 journals led to one publication. We have exemplified how the prevalence of common environmental problems in housing environments...

As a brazing foil, 4004 Al alloy has good welding performance. However, the high Si content decreases the plasticity of the alloy. To improve the plasticity of 4004 Al alloy and subsequently improve the productivity of 4004 Al foil or 434 composite foil, 4004 Al alloy was modified by Al-10%Sr master alloy. Modification effects of an additional amount of Sr, modification temperature, and holding time on 4004 aluminum alloy were studied by orthogonal design. The results showed that the greatest impact parameter of 4004 aluminum alloy modification was the additional amount of Sr, followed by holding time and modification temperature. The optimum modification parameters obtained by orthogonal design were as follows: Sr addition of 0.04%, holding time of 60 min, and modification temperature of 760°C. The effect of Sr addition on modification was analyzed in detail based on orthogonal results. With increasing of Sr addition, elongation of 4004 alloy increased at first, and decreased after reaching the maximum value.

It is well known that in design of traditional magneto-rheological brake (MRB), coils are placed on the cylindrical housing of the brake. In this study, a new configuration of MR brake with coils placed on the side housings of the brake is proposed and analyzed. After briefly explaining the operating principle of the proposed configuration, the braking torque of the MR brake is analyze based on Bingham-plastic rheological model of MR fluid. The optimization of the proposed and conventional MR brakes is then performed considering maximum braking torque and mass of the brake. Based on the optimal results, a comparison between the proposed MR brakes and the conventional ones is undertaken. In addition, experimental test of the MR brakes is conducted and the results are presented in order to validate the performance characteristics of the proposed MR brake.

Full Text Available Beehive houses of Suruç are completely built from sun dried mudbrick. Traditionally, rural house of Suruç plain is beehive houses. It has known that these houses have been used for centuries. These houses rooms have square plan and each room have conical roof. In terms of their own characteristic, Suruç beehive houses different from other conical or dome roofed houses such as beehive house of Harran, Trullo and Clochán. Basically there are four usage spaces; living rooms, designs of granaries, barn or folds and haylofts which are respectively arranged from south to north. These usage spaces are connected to each other with eyvans or gates without door. As requirement of rural life, these houses have some outbuildings such as tendur (tandoor, kadin (hayloft, gom (open folder, ça’l, lod and seki (terrace. Due to some environmental and socio-economic problems have caused migration from countryside to cities during the last 30 years. As a result of this, the Suruç beehive houses have either disused or abandoned completely. In addition, especially in last 30 years, the villagers in the area have begun to prefer building the reinforced concrete houses. This has led some of the Suruç beehive houses either to be destroyed or abandoned. Recent survived examples of these houses can be seen in Kara, Yatırtepe and Boztepe villages

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

2016-01-01

Natural enzymes use molecular recognition to perform exquisitely selective transformations on nucleic acids, proteins, and natural products. Rhodium(II) catalysts mimic this selectivity, using molecular recognition to allow selective modification of proteins with a variety of functionalized diazo reagents. The rhodium catalysts and the diazo reactivity have been successfully applied to a variety of protein folds, the chemistry succeeds in complex environments such as cell lysate, and a simple protein blot method accurately assesses modification efficiency. The studies with rhodium catalysts provide a new tool to study and probe protein-binding events, as well as a new synthetic approach to protein conjugates for medical, biochemical, or materials applications. © 2016 Elsevier Inc.

Suhendri; Koerniawan, M. D.

2017-03-01

Modern buildings in Indonesia rely mostly on artificial lighting, heating, cooling and ventilation. It means more energy is used to drive mechanical appliances, and presumably not sustainable. Meanwhile modern buildings consume much energy, traditional architectures are known as the source of knowledge for sustainable, energy efficient and climate responsive design. Noticeably, one of the differences between modern and traditional buildings in Indonesia is shown in their strategy to provide thermal comfort to the user. Traditional buildings use natural ventilation, but modern buildings use mechanical air conditioning. By focusing on wind-driven ventilation, the study aims to investigate natural ventilation strategy of Indonesian traditional house, and their potential improvement to be used in modern Indonesian buildings. Three traditional houses are studied in this research, representing west, central, and east Indonesia. The houses are Lampung traditional house, Javanese traditional house, and Toraja traditional house. CFD simulation is conducted to simulate wind-driven ventilation behaviour and the temperature of the buildings. Concisely, the wind-natural ventilation of case study houses is potential to provide thermal comfort inside the houses. However, the strategy still can be optimized by adding some other passive design strategies: sun-shading; vegetation; or buildings arrangement in the traditional dwelling. Consideration about the roof’s shape and windows position to the roof is important as well to create a uniform air distribution.

How to Design Buildings, Housing Estates and Towns So That Their Impact On the Environment Will Be Acceptable?

Science.gov (United States)

Majerska-Pałubicka, Beata

2017-10-01

Currently, there is a tendency in architecture to search for solutions implementing the assumptions of the sustainable development paradigm. A number of them are components of architecture, which in the future will certainly affect urban planning and architecture to a much greater extent. On the one hand, an issue of great significance is the need to integrate sustainable system elements with the spatial structure of environmentally friendly architectural facilities and complexes and to determine their influence on design solutions as well as the implementation, operation and recycling, while on the other hand, it is very important to solve the problem of how to design buildings, housing estates and towns so that their impact on the environment will be acceptable, i.e. will not exceed the possibilities of natural environment regeneration and, how to cooperate in interdisciplinary design teams to reach an agreement and acceptance so as to achieve harmony between the built and natural environment, which is a basis of sustainable development. In this broad interdisciplinary context an increasing importance is being attached to design strategies, systems of evaluating designs and buildings as well as tools to support integrated activities in the field of architectural design. The above topics are the subject of research presented in this paper. The basic research aim of the paper is: to look for a current method of solving design tasks within the framework of Integrated Design Process (IDP) using modern design tools and technical possibilities, in the context of sustainable development imperative, including, the optimisation of IDP design strategies regarding the assumptions of conscious creation of sustainable built environment, adjusted to Polish conditions. As a case study used examples of Scandinavian housing settlements, sustainable in a broad context.

Two industrial scale, 'ROBO' type 60 Co gamma irradiation facilities have recently been put into operation in Syria and Peru, and the dosimetry commissioning of both plants have been carried out to determine dose distribution within products and to calculate plant parameters such as efficiency, dose uniformity ratio and throughput. There are some design modifications between the two plants in connection with the location of the carriers with respect to the source plaque and also to each other. The effect of these construction modifications on the plant parameters is discussed in the analysis of the dose distribution data measured in the carriers with depth and height among the four irradiation rows on both sides of the source plaque. The plant parameters were also calculated for different product densities using the technical data of the facilities, and the calculated and measured results were compared to each other

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.

Melt spreading code assessment, modifications, and initial application to the EPR core catcher design

International Nuclear Information System (INIS)

Farmer, M.T.; Basu, S.

2009-01-01

The Evolutionary Power Reactor (EPR) is a 1,600-MWe Pressurized Water Reactor (PWR) that is undergoing a design certification review by the U.S. Nuclear Regulatory Commission (NRC). The EPR severe accident design philosophy is predicated upon the fact that the projected power rating results in a narrow margin for in-vessel melt retention by external flooding. As a result, the design addresses ex-vessel core melt stabilization using a mitigation strategy that includes: 1) an external core melt retention system to temporarily hold core melt released from the vessel; 2) a layer of 'sacrificial' material that is admixed with the melt while in the core melt retention system; 3) a melt plug that, when failed, provides a pathway for the mixture to spread to a large core spreading chamber; and finally, 4) cooling and stabilization of the spread melt by controlled top and bottom flooding. The melt spreading process relies heavily on inertial flow of a low-viscosity admixed melt to a segmented spreading chamber, and assumes that the melt mass will be distributed to a uniform height in the chamber. The spreading phenomenon thus needs to be modeled properly in order to adequately assess the EPR design. The MELTSPREAD code, developed at Argonne National Laboratory, can model segmented, and both uniform and non-uniform spreading. The NRC is using MELTSPREAD to evaluate melt spreading in the EPR design. The development of MELTSPREAD ceased in the early 1990's, and so the code was first assessed against the more contemporary spreading database and code modifications, as warranted, were carried out before performing confirmatory plant calculations. This paper provides principle findings from the MELTSPREAD assessment activities and resulting code modifications, and also summarizes the results of initial scoping calculations for the EPR plant design and preliminary plant analyses, along with the plan for performing the final set of plant calculations including sensitivity studies

1987-01-01

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

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.

Vilmann, Carl

1991-01-01

This analysis of the deformation of rotary combustion engine housings targeted the following objectives: (1) the development and verification of a finite element model of the trochoid housing, (2) the prediction of the stress and deformation fields present within the trochoid housing during operating conditions, and (3) the development of a specialized preprocessor which would shorten the time necessary for mesh generation of a trochoid housing's FEM model from roughly one month to approximately two man hours. Executable finite element models were developed for both the Mazda and the Outboard Marine Corporation trochoid housings. It was also demonstrated that a preprocessor which would hasten the generation of finite element models of a rotary engine was possible to develop. The above objectives are treated in detail in the attached appendices. The first deals with finite element modeling of a Wankel engine center housing, and the second with the development of a preprocessor that generates finite element models of rotary combustion engine center housings. A computer program, designed to generate finite element models of user defined rotary combustion engine center housing geometries, is also included.

High performance integrated solar combined cycles with minimum modifications to the combined cycle power plant design

Manente, Giovanni

2016-01-01

Highlights: • Off-design model of a 390 MW_e three pressure combined cycle developed and validated. • The off-design model is used to evaluate different hybridization schemes with solar. • Power boosting and fuel saving with different design modifications are considered. • Maximum solar share of total electricity is only 1% with the existing equipment. • The maximum incremental solar radiation-to-electrical efficiency approaches 29%. - Abstract: The integration of solar energy into natural gas combined cycles has been successfully demonstrated in several integrated solar combined cycles since the beginning of this decade in many countries. There are many motivations that drive investments on integrated solar combined cycles which are primarily the repowering of existing power plants, the compliance with more severe environmental laws on emissions and the mitigation of risks associated with large solar projects. Integrated solar combined cycles are usually developed as brownfield facilities by retrofitting existing natural gas combined cycles and keeping the existing equipment to minimize costs. In this work a detailed off-design model of a 390 MW_e three pressure level natural gas combined cycle is built to evaluate different integration schemes of solar energy which either keep the equipment of the combined cycle unchanged or include new equipment (steam turbine, heat recovery steam generator). Both power boosting and fuel saving operation strategies are analyzed in the search for the highest annual efficiency and solar share. Results show that the maximum incremental power output from solar at design solar irradiance is limited to 19 MW_e without modifications to the existing equipment. Higher values are attainable only including a larger steam turbine. High solar radiation-to-electrical efficiencies in the range 24–29% can be achieved in the integrated solar combined cycle depending on solar share and extension of tube banks in the heat recovery

Mixed-strain housing for female C57BL/6, DBA/2, and BALB/c mice: validating a split-plot design that promotes refinement and reduction.

Inefficient experimental designs are common in animal-based biomedical research, wasting resources and potentially leading to unreplicable results. Here we illustrate the intrinsic statistical power of split-plot designs, wherein three or more sub-units (e.g. individual subjects) differing in a variable of interest (e.g. genotype) share an experimental unit (e.g. a cage or litter) to which a treatment is applied (e.g. a drug, diet, or cage manipulation). We also empirically validate one example of such a design, mixing different mouse strains -- C57BL/6, DBA/2, and BALB/c -- within cages varying in degree of enrichment. As well as boosting statistical power, no other manipulations are needed for individual identification if co-housed strains are differentially pigmented, so also sparing mice from stressful marking procedures. The validation involved housing 240 females from weaning to 5 months of age in single- or mixed- strain trios, in cages allocated to enriched or standard treatments. Mice were screened for a range of 26 commonly-measured behavioural, physiological and haematological variables. Living in mixed-strain trios did not compromise mouse welfare (assessed via corticosterone metabolite output, stereotypic behaviour, signs of aggression, and other variables). It also did not alter the direction or magnitude of any strain- or enrichment-typical difference across the 26 measured variables, or increase variance in the data: indeed variance was significantly decreased by mixed- strain housing. Furthermore, using Monte Carlo simulations to quantify the statistical power benefits of this approach over a conventional design demonstrated that for our effect sizes, the split- plot design would require significantly fewer mice (under half in most cases) to achieve a power of 80%. Mixed-strain housing allows several strains to be tested at once, and potentially refines traditional marking practices for research mice. Furthermore, it dramatically illustrates the

Modifications to nuclear power plants. Safety guide

As the Building America Program has grown to include a large and diverse cross section of the home building industry, accurate and consistent analysis techniques have become more important to help all program partners as they perform design tradeoffs and calculate energy savings for prototype houses built as part of the program. This document illustrates some of the analysis concepts proven effective and reliable for analyzing the transient energy usage of advanced energy systems as well as entire houses. The analysis procedure described here provides a starting point for calculating energy savings of a prototype house relative to two base cases: builder standard practice and regional standard practice. Also provides building simulation analysis to calculate annual energy savings based on side-by-side short-term field testing of a prototype house.

Independent design review report for truck number 1 modifications for flammable gas tanks

International Nuclear Information System (INIS)

Wilson, G.W.

1997-01-01

The East and West Tank Farm Standing Order 97-01 requires that the PMST be modified to include purging of the enclosed space underneath the shielded receiver weather cover per National Fire Protection Association (NFPA) 496, Purged and Pressurized Enclosures for Electrical Equipment. The Standing Order also requires that the PMST be modified by replacing the existing electrical remote latch (RLU) unit with a mechanical remote latch unit. As the mechanical remote latch unit was exactly like the RLU installed on the Rotary Mode Core Sampler Trucks (RMCST) and the design for the RMCST went through formal design review, replacing the RLU was done utilizing informal design verification and was completed per work package ES-97-0028. As the weather cover purge was similar to the design for the RMCSTS, this design was reviewed using the independent review method with multiple independent reviewers. A function design criteria (WHC-SD-WM-FDC-048, Functional Design Criteria for Core Sampling in Flammable Gas Watch List Tanks) provided the criteria for the modifications. The review consisted of distributing the design review package to the reviewers and collecting and dispositioning the RCR comments. The review package included the ECNs for review, the Design Compliance Matrix, copies of all drawings affected, and copies of outstanding ECNs against these drawings. A final meeting was held to ensure that all reviewers were aware of the changes to ECNs from incorporation of RCR comments

Assessing the engineering performance of affordable net-zero energy housing

Science.gov (United States)

Wallpe, Jordan P.

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

House has a paramount meaning in human life. Provision of adequate housing will be able to improve the quality of life. Provision of an affordable house is a major step to fulfilling the needs of houses in the big city. Medan has built a lot of affordable houses, and mostly it takes place in the suburbs. Although the affordable house is for low-income people, it must be worthy of its physical condition, affordable in the budget and healthy for its users. House often saw only as physical alone, the provision of a house only to achieve solely in quantity regardless its quality. This study aims to examine the condition of affordable houses in the suburbs of Medan. The research method used qualitative descriptive, using indicator according to affordable healthy house standard according to the regulation in Indonesia and other related theories. This study took place in Medan by taking three areas in the suburbs of Medan. The results show that most affordable houses in the suburbs of Medan are unhealthy. There are several design recommendations for the houses to meet the affordable healthy house category; the most important is the addition of ventilation and window holes.

Radon reduction in crawl-space houses

International Nuclear Information System (INIS)

Osborne, M.C.; Moore, D.G.; Southerlan, R.E.; Brennan, T.; Pyle, B.E.

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

Actual proof study of energy autonomous house; Energy jiritsu house no jissho jikken. 1

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.

Bioclimatic Analysis in Pre‐Design Stage of Passive  House in Indonesia

Directory of Open Access Journals (Sweden)

Santy

2017-03-01

Full Text Available The objective of this study is to investigate the climate characteristics of Indonesian regions using an Olgyay Bioclimatic chart, a Givoni–Milne Bioclimatic chart and a Mahoney Table as the pre‐design stage in the development of a passive house design standard for residential house construction in Indonesia. Jakarta was the city chosen for deep analysis, because it represents most of the Indonesian regions in terms of temperature and relative humidity. The Olgyay Bioclimatic chart showed that the climate needs a high wind velocity to counteract the vapor pressure and shading in order to reduce solar gain entering the building. The Givoni–Milne Bioclimatic chart proposed natural ventilation and shading devices, while the Mahoney Table recommends open spaces for protection against hot wind, rooms single‐banked and permanent provision for air movement. The composite size of the opening at body height is better to allow the wind to counter the high levels of humidity and temperature. Heavy walls and roofs are suggested, as well as the provision of protection devices for the high amount of rainfall. Energy simulation was also done to investigate the effectiveness of the passive strategy proposed by the bioclimatic analysis. These results give a contribution as the indispensable basis for the development of a passive house standard in Indonesia.

Mixed-strain housing for female C57BL/6, DBA/2, and BALB/c mice: validating a split-plot design that promotes refinement and reduction

Michael Walker

2016-01-01

Full Text Available Abstract Background Inefficient experimental designs are common in animal-based biomedical research, wasting resources and potentially leading to unreplicable results. Here we illustrate the intrinsic statistical power of split-plot designs, wherein three or more sub-units (e.g. individual subjects differing in a variable of interest (e.g. genotype share an experimental unit (e.g. a cage or litter to which a treatment is applied (e.g. a drug, diet, or cage manipulation. We also empirically validate one example of such a design, mixing different mouse strains -- C57BL/6, DBA/2, and BALB/c -- within cages varying in degree of enrichment. As well as boosting statistical power, no other manipulations are needed for individual identification if co-housed strains are differentially pigmented, so also sparing mice from stressful marking procedures. Methods The validation involved housing 240 females from weaning to 5 months of age in single- or mixed- strain trios, in cages allocated to enriched or standard treatments. Mice were screened for a range of 26 commonly-measured behavioural, physiological and haematological variables. Results Living in mixed-strain trios did not compromise mouse welfare (assessed via corticosterone metabolite output, stereotypic behaviour, signs of aggression, and other variables. It also did not alter the direction or magnitude of any strain- or enrichment-typical difference across the 26 measured variables, or increase variance in the data: indeed variance was significantly decreased by mixed- strain housing. Furthermore, using Monte Carlo simulations to quantify the statistical power benefits of this approach over a conventional design demonstrated that for our effect sizes, the split- plot design would require significantly fewer mice (under half in most cases to achieve a power of 80 %. Conclusions Mixed-strain housing allows several strains to be tested at once, and potentially refines traditional marking practices

Safety of modifications at nuclear power plants - the role of minor modifications and human and organisational factors

International Nuclear Information System (INIS)

2005-01-01

in the present report. The ultimate responsibility for plant safety lies with the licensee. Consequently, modification processes at the utilities are controlled by written procedures. The modification processes vary depending on the type and scope of the modification. Large modifications generally lead to fewer problems, because these projects are given a great deal of attention and resources together with flexibility in milestones and timing of activities. In contrast, minor modifications seem to, according to recent experience, represent a generic challenge because they are less likely to be recognised as safety significant. Similar kinds of challenges may arise during plant maintenance, when changes in the design or materials may be made without anyone recognising that the maintenance work has actually led to functional modification of plant equipment. A modification process, in which possible safety influences are assessed early, may improve nuclear safety to a significant extent and, at the same time, reduce overall modification cost. Screening of intended changes can be used to estimate design and analysis effort required in the modification process. In the screening, it should be observed that system complexity sometimes may have unexpected impacts. Screening criteria should address the safety significance of the systems and components modified. Also, the impact of the changes on tasks performed by operators and maintainers should be assessed. Major modification projects should always include an analysis of both technical and human contributions to plant operability and maintainability as a part of their comprehensive review process. It is important to create awareness and understanding of the potential safety impacts of modifications at NPPs. This awareness may be improved by collecting and disseminating information about modification-related events. Good results may only be achieved by integrating technical and human factors considerations in the safety

1993-01-01

Within the framework of the European Community's PHARE Programme of improvement to facilities, their operating systems, equipment and buildings of the Kozloduy NPP in Bulgaria, plant safety during seismic events is considered to be an issue of overriding importance, especially in view of the earthquakes the region suffered during the last decade. Westinghouse Energy Systems International (WESI) and Empresarios Agrupados (EA) have initiated an intensive programme for physical upgrading of equipment with a view to augmenting its seismic capability and, at the same time, to studying design modifications in the diesel-generator buildings, pump house and main building structures (turbines, electrical building). The implementation of these modifications requires an in situ inspection of the real conditions of the various elements, analyses, conceptual design and detail engineering, all of which has to be done in short periods of time using resources available at the plant. This activity is performed by the companies mentioned above, with the collaboration of two engineering companies, Energoproekt of Bulgaria and INITEC of Spain. This paper describes the activities developed and the treatment given to the various aspects of improvement of the seismic capability of equipment and structures. (author)

Innovativeness in housing construction and the role of the Housing Fund: From residence to an integral living environment

Directory of Open Access Journals (Sweden)

Zdravko Mlinar

2008-01-01

Full Text Available This article attempts to contribute to clarification of the conditions and actors impacting innovativeness in housing construction and the management of space. It concentrates on the role of the Slovenian national Housing Fund, which is too restricted and lacks appropriate legal bases and means, and also – according to some evaluations – the aspiration to assert its innovative and developmental role. The Fund is focussed on the financial-economic aspects of providing non-profit housing and housing for the market. Currently attention is primarily directed towards its legal-organizational structure and its transformation into an independent company. This neglects broader consideration of socio-spatial change, developmental directions and values in the context of the information age (Lisbon Strategy, which call for innovative sociological, architectural and urbanistic solutions. Mindsets, legal norms and institutions in Slovenia are lagging behind these changes. Thus, housing is still mainly treated as a discrete segment. In order to perform their task in this new framework, which demands more integral treatment of the everyday living environment and reintegration of living, work and recreation, the mandate of the housing funds must no longer be confined merely to housing. Several examples of innovative design as well as their limitations are presented, together with examples of good international practice.

This paper describes a community-engaged study with the Los Angeles House and Ball scene, in which the perspectives of the leaders of these communities are captured to better understand how the House and Ball communities may protect and/or increase its members’ risks for HIV infection. Data were collected through in-depth interviews with House parents (N=26). This study identified key features of both support (e.g., family and support; acceptance; validation and recognition) and risk (e.g., members’ struggle to maintain status in the Ballroom scene; sex work; substance use; danger of becoming too involved in the Ball community; perception and stigma of Ballroom scene within the larger gay community) within these communities. Findings are discussed in relation to framing how to leverage the supportive aspects of the House and Ball communities to design relevant HIV prevention interventions. PMID:22206442

Standard approach to plant modifications

International Nuclear Information System (INIS)

Mecredy, R.C.

1988-01-01

Organizational and management approaches to the design, installation, and turnover of nuclear plant modifications have changed dramatically in the last 10 to 15 yr. In response to these changes, organizational and individual responsibilities have been defined and management systems have been established at Rochester Gas and Electric (RG and E) Corporation to ensure that high-quality plant modifications are installed in a timely manner that satisfies user needs at minimal cost

Modifications at operating nuclear power plants

International Nuclear Information System (INIS)

Duffy, T.J.; Gazda, P.A.

1985-01-01

Modifications at operating nuclear power plants offer the structural engineer many challenges in the areas of scheduling of work, field adjustments, and engineering staff planning. The scheduling of structural modification work for operating nuclear power plants is normally closely tied to planned or unplanned outages of the plant. Coordination between the structural engineering effort, the operating plant staff, and the contractor who will be performing the modifications is essential to ensure that all work can be completed within the allotted time. Due to the inaccessibility of some areas in operating nuclear power plants or the short time available to perform the structural engineering in the case of an unscheduled outrage, field verification of a design is not always possible prior to initiating the construction of the modification. This requires the structural engineer to work closely with the contractor to promptly resolve problems due to unanticipated interferences or material procurement problems that may arise during the course of construction. The engineering staff planning for structural modifications at an operating nuclear power plant must be flexible enough to permit rapid response to the common ''fire drills,'' but controlled enough to ensure technically correct designs and to minimize the expenditure of man-hours and the resulting engineering cost

Housing First and Social Integration: A Realistic Aim?

Directory of Open Access Journals (Sweden)

Deborah Quilgars

2016-10-01

Full Text Available Housing First is now dominating discussions about how best to respond to homelessness among people with high and complex needs throughout the EU and in several countries within the OECD. Whilst recognised internationally as an effective model in addressing homelessness, little attention has been given as to whether Housing First also assists previously homeless people become more socially integrated into their communities. This paper reviews the available research evidence (utilising a Rapid Evidence Assessment methodology on the extent to which Housing First services are effective in promoting social integration. Existing evidence suggests Housing First is delivering varying results in respect of social integration, despite some evidence suggesting normalising effects of settled housing on ontological security. The paper argues that a lack of clarity around the mechanisms by which Housing First is designed to deliver ‘social integration’, coupled with poor measurement, helps explain the inconsistent and sometimes limited results for Housing First services in this area. It concludes that there is a need to look critically at the extent to which Housing First can deliver social integration, moving the debate beyond the successes in housing sustainment and identifying what is needed to enhance people’s lives in the longer-term.

The Optimal Design Method and Standardized Mathematical Model of Tooth Profile Modification of Spur Gear

Directory of Open Access Journals (Sweden)

Wenjie Mei

2016-01-01

Full Text Available The paper reports a tooth profile modification method of spur gear. After establishing a standardized mathematical model for optimized tooth profile and simulating meshing process with ANSYS finite element analysis, we obtained 625 groups of gear models with different modification parameters. The group with minimum transmission errors owns the optimal parameters. Genetic algorithm was adopted in the entire process for the purpose of reducing the variation of transmission errors in meshing process. The arc and parabolic modification were doing the same processing. After comparing the transmission errors fluctuation produced by the meshing process of gear of nonmodification with arc modification and parabolic modification, we found that the best modification effects of arc modification and parabolic modification were both reduced by 90%. The modification method makes the gear drive process more stable and efficient, and it is also promising in general application for gear drive.

A framework for evaluating WTP for BIPV in residential housing design in developing countries: A case study of North Cyprus

International Nuclear Information System (INIS)

Radmehr, Mehrshad; Willis, Ken; Kenechi, Ugo Elinwa

2014-01-01

This paper explores people's preferences for a Built in Photovoltaic (BIPV) renewable energy system to be integrated into housing construction. A novel methodology was developed, to study the case of Northern Cyprus, for better understanding of possibilities that abound in BIPV integration. The methodology incorporates Building Information Modeling (BIM) as a real-time design and economic assessment tool for BIPV choices. This serves to benefit both the construction companies and potential house owners in their decision-making. In addition, it uses a Contingent Valuation (CV) method to assess the Willingness to Pay (WTP) and the Willingness to Accept (WTA) compensation. The results indicate that the capital cost of PV is not instrumental in choice, and a lower feed-in tariff could be acceptable

2016-01-01

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.

Full Text Available RESUMEN En enero de 1945, John Entenza, editor de la revista californiana Arts & Architecture, puso en marcha el programa Case Study House, un ambicioso proyecto cuyo firme objetivo era investigar las posibilidades y soluciones del problema de la vivienda al que se enfrentaba los Estados Unidos de la posguerra. 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.

Designing the user interfaces of a behavior modification intervention for obesity & eating disorders prevention.

Moulos, Ioannis; Maramis, Christos; Mourouzis, Alexandros; Maglaveras, Nicos

2015-01-01

The recent immense diffusion of smartphones has significantly upgraded the role of mobile user interfaces in interventions that build and/or maintain healthier lifestyles. Indeed, high-quality, user-centered smartphone applications are able to serve as advanced front-ends to such interventions. These smartphone applications, coupled with portable or wearable sensors, are being employed for monitoring day to day health-related behaviors, including eating and physical activity. Some of them take one step forward by identifying unhealthy behaviors and contributing towards their modification. This work presents the design as well as the preliminary implementation of the mobile user interface of SPLENDID, a novel, sensor-oriented intervention for preventing obesity and eating disorders in young populations. This is implemented by means of an Android application, which is able to monitor the eating and physical activity behaviors of young individuals at risk for obesity and/or eating disorders, subsequently guiding them towards the modification of those behaviors that put them at risk. Behavior monitoring is based on multiple data provided by a set of communicating sensors and self-reported information, while guidance is facilitated through a feedback/encouragement provision and goal setting mechanism.

2017-04-04

The University of Texas at Austin and The Technical University of Munich 2015 Solar Decathlon house is called Nexushaus because it combines UT Austin and TUM students in an affordable modular residential green building in the context of Austin, Texas, based on shape forming principles found in nature that demonstrates transformative technologies in Zero Net Energy, Zero Net Water and Carbon Neutrality. To meet the needs of the competition, a portable modular design has been developed with an assembly that enables ease of installation and both quantitative and qualitative performance in the design. The prefabricated house sits lightly on the land and forms the superstructure for photovoltaic technologies, rainwater collection, aquaculture and permaculture gardening and indoor/outdoor living. The ultimate goal of Nexushaus is to serve as a potential prototype for a next-generation modular home that could be reproduced in mass in an assembly plant in Austin.

This report gives an outline of some of the main modifications carried out around the Reactor Core on the Research Reactor JRR-2, at the Tokai Research Establishment of JAERI. The JRR-2 was shut down in December 1973, to improve it in heavy water leakage from the metal packing between core tank and support ring, corrosion of the lower shielding plug, and fault in the control-rod mechanism. Main modifications were a standing seal weld at the support ring to stop heavy water leakage, replacement of the reactor top shield and improvement of the helium system. The control-rod assemblies and the refueling devices were replaced by the newly designed ones also. In addition to the modification plan, the irradiated air exhaust system was improved to reduce radioactive argon gas release through the stack. Works were completed successfully in September 1975. But a light water leakage occurred at the stand pipe below the light water tank on November 11, 1975, which was repaired in about 4 months. When considering the operation of above 5,000 hours after the modification, however, the quality of the modification work may be said to be quite satisfactory. The present report in which works to the completion are described may be valuable as a record of reactor modification which is a new experience at JAERI. (auth.)

Value-impact assessment of safety-related modifications

International Nuclear Information System (INIS)

Knowles, W.M.C.; Dinnie, K.S.; Gordon, C.W.

1992-01-01

Like other nuclear utilities, Ontario Hydro, as part of its risk management activities, continually assesses the safety of its nuclear operations. In addition, new regulatory requirements are being applied to the older nuclear power plants. Both of these result in proposed plant modifications designed to reduce the risk to the public. However, modifications to an operating plant can have serious economic effects, and the resources, both financial and personnel, required for the implementation of these modifications are limited. Thus, all potential benefits and effects of a proposed modification must be thoroughly investigated to judge whether the modification is beneficial. Ontario Hydro has begun to use comprehensive value-impact assessments, utilizing plant-specific probabilistic risk assessments (PRAs), as tools to provide an informed basis for judgments on the benefit of safety-related modifications. The results from value-impact assessments can also be used to prioritize the implementation of these modifications

Conservation value of clustered housing developments.

Lenth, Buffy A; Knight, Richard L; Gilgert, Wendell C

2006-10-01

Traditionally, exurban lands in Colorado have been subdivided into a grid of parcels ranging from 2 to 16 ha. From an ecological perspective, this dispersed pattern of development effectively maximizes the individual influence of each home on the land. Clustered housing developments, designed to maximize open space, are assumed to benefit plant and wildlife communities of conservation interest. They have become a popular alternative for rural development despite the lack of empirical evidence demonstrating their conservation benefits. To better inform rural land-use planning, we evaluated clustered housing developments by comparing their spatial pattern with that of dispersed housing developments and by comparing their conservation value with that of both dispersed housing developments and undeveloped areas in Boulder County, Colorado. We used four indicators to assess conservation value: (1) densities of songbirds, (2) nest density and survival of ground-nesting birds, (3) presence of mammals, and (4) percent cover and proportion of native and non-native plant species. Clustered and dispersed housing developments did not differ on the majority of variables we examined. Both types of housing development had significantly higher densities of non-native and human-commensal species and significantly lower densities of native and human-sensitive species than undeveloped areas. More rigorous ecological guidelines and planning on a regional scale may help create clustered developments with higher conservation value.

Use of a Scale Model in the Design of Modifications to the NASA Glenn Icing Research Tunnel

Canacci, Victor A.; Gonsalez, Jose C.; Spera, David A.; Burke, Thomas (Technical Monitor)

2001-01-01

Major modifications were made in 1999 to the 6- by 9-Foot (1.8- by 2.7-m) Icing Research tunnel (IRT) at the NASA Glenn Research Center, including replacement of its heat exchanger and associated ducts and turning vanes, and the addition of fan outlet guide vanes (OGV's). A one-tenth scale model of the IRT (designated as the SMIRT) was constructed with and without these modifications and tested to increase confidence in obtaining expected improvements in flow quality around the tunnel loop. The SMIRT is itself an aerodynamic test facility whose flow patterns without modifications have been shown to be accurate, scaled representations of those measured in the IRT prior to the 1999 upgrade program. In addition, tests in the SMIRT equipped with simulated OGV's indicated that these devices in the IRT might reduce flow distortions immediately downstream of the fan by two thirds. Flow quality parameters measured in the SMIRT were projected to the full-size modified IRT, and quantitative estimates of improvements in flow quality were given prior to construction. In this paper, the results of extensive flow quality studies conducted in the SMIRT are documented. Samples of these are then compared with equivalent measurements made in the full-scale IRT, both before and after its configuration was upgraded. Airspeed, turbulence intensity, and flow angularity distributions are presented for cross sections downstream of the drive fan, both upstream and downstream of the replacement flat heat exchanger, in the stilling chamber, in the test section, and in the wakes of the new comer turning vanes with their unique expanding and contracting designs. Lessons learned from these scale-model studies are discussed.

1998-01-01

Having as purpose the improvement of fire safety at the Cernavoda NPP - both in the prevention and the protection aspects in the case of fire - we implemented some modifications in the CANDU 6 standard design. These improvements are inspired, mainly, from two sources: the world-wide achievements in the field of fire protection techniques, introduced in nuclear power plants since the middle of 70's, when the CANDU 6 design was completed; the national practice and experience in fire protection, usually applied in industrial objectives (conventional power plants, in particular). The absence of any incident may be considered as a proof of the efficiency of the implemented fire preventing and protection measures. (author)

Housing First: exploring participants’ early support needs

Science.gov (United States)

2014-01-01

Background Housing First has become a popular treatment model for homeless adults with mental illness, yet little is known about program participants’ early experiences or trajectories. This study used a mixed methods design to examine participant changes in selected domains 6 months after enrolment in a Canadian field trial of Housing First. Methods The study sample included 301 participants receiving the Housing First intervention at the Toronto site of the At Home/Chez Soi project. This study used a pre-post design to compare quantitative 6-month outcome data to baseline values in key domains and multivariate regression to identify baseline demographic, clinical or service use variables associated with observed changes in these domains. In addition, qualitative data exploring participant and service provider perspectives and experiences was collected via stakeholder interviews and focus groups, and analyzed using thematic analysis. Results The majority (60 to 72%) of participants followed the expected trajectory of improvement, with the remaining experiencing difficulties in community integration, mental health symptom severity, substance use, community functioning and quality of life 6 months after program enrolment. Diagnosis of psychotic disorder was associated with a reduction in quality of life from baseline to 6-months, while substance use disorders were associated with reduced mental illness symptoms and substance use related problems and an improvement in quality of life. Participants housed in independent housing at 6-months had greater improvements in community integration and quality of life, and greater reduction in mental illness symptoms, compared to those not independently housed. The quality of the working alliance was positively associated with improvements in physical and psychological community integration and quality of life. Qualitative data provided a unique window into the loneliness and isolation experienced by Housing First

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

The Advanced Envelope Research effort will provide factory homebuilders with high performance, cost-effective alternative envelope designs. In the near term, these technologies will play a central role in meeting stringent energy code requirements. For manufactured homes, the thermal requirements, last updated by statute in 1994, will move up to the more rigorous IECC 2012 levels in 2013, the requirements of which are consistent with site built and modular housing. This places added urgency on identifying envelope technologies that the industry can implement in the short timeframe. The primary goal of this research is to develop wall designs that meet the thermal requirements based on 2012 IECC standards. Given the affordable nature of manufactured homes, impact on first cost is a major consideration in developing the new envelope technologies. This work is part of a four-phase, multi-year effort. Phase 1 identified seven envelope technologies and provided a preliminary assessment of three selected methods for building high performance wall systems. Phase 2 focused on the development of viable product designs, manufacturing strategies, addressing code and structural issues, and cost analysis of the three selected options. An industry advisory committee helped critique and select the most viable solution to move further in the research -- stud walls with continuous exterior insulation. Phase 3, the subject of the current report, focused on the design development of the selected wall concept and explored variations on the use of exterior foam insulation. The scope also included material selection, manufacturing and cost analysis, and prototyping and testing.

flexZhouse: New business model for affordable housing in Malaysia

Directory of Open Access Journals (Sweden)

Mohd Zairul bin Mohd Noor

2017-01-01

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

Role of in-house safety analysis and research activities in regulatory decision making

International Nuclear Information System (INIS)

Pradhan, Santosh K.; Nagrale, Dhanesh B.; Gaikwad, Avinash J.

2015-01-01

Achievement of an acceptable level of nuclear safety is an essential requirement for the peaceful utilization of nuclear energy. The success of Global Nuclear Safety Regime is built upon a foundation of research. Such research has been sponsored by Governments and industry and has led to improved designs, safer and more reliable plant operation, and improvements in operating plant efficiency. A key element of this research has been the nuclear safety research performed or sponsored by regulatory organizations. In part, it has been the safety research performed or sponsored by regulatory organizations that has contributed to improved safety and has laid the foundation for activities such as risk-informed regulation, plant life extension, improved plant performance (e.g. power uprates) and new plant designs. The regulatory research program is meant to improve the regulatory authority’s knowledge where uncertainty exists, where safety margins are not well-characterized, and where regulatory decisions need to be confirmed in existing or new designs and technologies. The regulatory body get research initiated either in-house or by the licensee or through technical support organizations (TSOs). Research and analysis carried out within the regulatory body is of immense value in this context. This could be in the form of analysis of safety significant events, analysis of severe accidents, review of operating experience, independent checks of critical designs and even review of operator responses under different situations towards arriving at modifications to training programmes and licensing procedures for operating personnel. A latent benefit of regulatory research carried out by the regulators themselves is that it improves their technical competence considerably which in turn leads to high quality safety reviews and improved regulation in general. The aim of the present paper is to provide an overview of role of regulatory research and the in-house regulatory safety

TWO MODIFICATIONS OF SCALERS FOR RATE STUDIES

Two simple modifications to nuclear scalers have been developed. The first involves an automatic stepping switch which permits a single scaler to be actuated by up to four Geiger counters in sequence and to record the time to reach a preset count for each. The second modification is designed to pick a pulse off a conventional scaler when a preset count has been reached and to use the pulse to actuate a recorder. Both modifications considerably extend the utility of conventional scalers.

Suggestions of Policy Direction to Improve the Housing Quality in South Korea

Directory of Open Access Journals (Sweden)

Miyeon Park

2016-05-01

Full Text Available Following the recent global climate changes, many countries, including developed nations, are announcing greenhouse gas (GHG reduction targets and are actively participating in reducing GHG. Therefore, the role of the building sector on reducing GHG is being emphasized, and the establishment of policy structures for both making environmentally friendly capacity compulsory and improving the housing quality is being demanded. South Korea is also developing a policy for improving housing quality, but in order to achieve more competitive growth, this must be preceded by an analysis of current policy status within various countries on improving housing quality. This study aims to suggest direction about policies that will improve the housing quality in South Korea. For this, the policies of major countries were able to categorize and compare according to three major categories (performance, function, and aesthetics, and seven factors (safety, durability, cost and maintenance, response to residents’ needs, habitability, energy saving, and building design regarding housing quality. As a result, from the performance aspect, policy directions were suggested for safe housing, the urban environment, regeneration of quality stock, and the usage of existing stock; from the functional aspect, policies for improving housing quality that responds to the aging population and energy saving housing were suggested; from the aesthetic aspect, housing designs that consider the urban environment were suggested.

Evaluation of proposed panel closure modifications at WIPP

Energy Technology Data Exchange (ETDEWEB)

Allen, Lawrence E.; Silva, Matthew K.; Channell, James K.; Abel, John F.; Morgan, Dudley R.

2001-12-31

A key component in the design of the WIPP repository is the installation of concrete structures as panel seals in the intake and exhaust drifts after a panel has been filled with waste containers. As noted in the EPA final rule, the panel seal closure system is intended to block brine flow between the waste panels at the WIPP. On April 17, 2001, the DOE proposed seven modifications to the EPA concerning the design of the panel closure system. EPA approval of these modifications is necessary since the details of the panel design are specified in EPA’s final rule as a condition for WIPP certification. However, the EPA has not determined whether a rulemaking would be required for these proposed design modifications. On September 4, 2001, the DOE withdrew the request, noting that it would be resubmitted on a future date. The Environmental Evaluation Group (EEG) contracted with two engineers, Dr. John Abel and Dr. Rusty Morgan, to evaluate the proposed modifications. The EEG has accepted the conclusions and recommendations from these two experts: 1) replacement of Salado Mass Concrete with a generic salt-based concrete; 2) replacement of the explosion wall with a construction wall; 3) replacement of freshwater grouting with salt-based grouting; 4) option to allow surface or underground mixing; and 5) option to allow up to one year for completion of closure. The proposed modification to allow local carbonate river rock as aggregate is acceptable pending demonstration that no problems will exist in the resulting concrete. The proposed modification to give the contractor discretion in removal of steel forms is not supported. Instead, several recommendations are made to specifically reduce the number of forms left, thereby reducing potential migration pathways.

NCSU solar energy and conservation house. Final report

Energy Technology Data Exchange (ETDEWEB)

1981-10-01

A passive solar energy house has been built adjacent to the NCSU McKimmon Continuing Education Center. The house contains a two-story embedded sunspace, two Trombe walls, active solar hot water heating, thermal storage in a rock filled ceiling/floor, and numerous research treatments, and energy conservation features. (See attached photo brochure; Appendix 1). The house is completely decorated and furnished in an attractive manner and the exterior architecture is traditional and has broad consumer appeal. It is also thoroughly instrumented to monitor performance. The house is open to the public on weekends and numerous people come to visit on their own initiative and others take advantage of the close proximity to McKimmon while there attending conferences. The house will influence and motivate large numbers of people to consider solar and energy conservation facets in their homes and will provide data to substantiate performance to prospective home buyers and meaningful data on design and construction for builders.

Transforming paper-based assessment forms to a digital format: Exemplified by the Housing Enabler prototype app.

Science.gov (United States)

Svarre, Tanja; Lunn, Tine Bieber Kirkegaard; Helle, Tina

2017-11-01

The aim of this paper is to provide the reader with an overall impression of the stepwise user-centred design approach including the specific methods used and lessons learned when transforming paper-based assessment forms into a prototype app, taking the Housing Enabler as an example. Four design iterations were performed, building on a domain study, workshops, expert evaluation and controlled and realistic usability tests. The user-centred design process involved purposefully selected participants with different Housing Enabler knowledge and housing adaptation experience. The design iterations resulted in the development of a Housing Enabler prototype app. The prototype app has several features and options that are new compared with the original paper-based Housing Enabler assessment form. These new features include a user friendly overview of the assessment form; easy navigation by swiping back and forth between items; onsite data analysis; and ranking of the accessibility score, photo documentation and a data export facility. Based on the presented stepwise approach, a high-fidelity Housing Enabler prototype app was successfully developed. The development process has emphasized the importance of combining design participants' knowledge and experiences, and has shown that methods should seem relevant to participants to increase their engagement.

Kerman, Nick; Sylvestre, John; Aubry, Tim; Distasio, Jino

2018-03-20

Housing First is an effective intervention to stably house and alter service use patterns in a large proportion of homeless people with mental illness. However, it is unknown whether there are differences in the patterns of service use over time among those who do or do not become stably housed and what effect, if any, Housing First has on these differing service use patterns. This study explored changes in the service use of people with mental illness who received Housing First compared to standard care, and how patterns of use differed among people who did and did not become stably housed. The study design was a multi-site randomized controlled trial of Housing First, a supported housing intervention. 2039 participants (Housing First: n = 1131; standard care: n = 908) were included in this study. Outcome variables include nine types of self-reported service use over 24 months. Linear mixed models examined what effects the intervention and housing stability had on service use. Participants who achieved housing stability, across the two groups, had decreased use of inpatient psychiatric hospitals and increased use of food banks. Within the Housing First group, unstably housed participants spent more time in prison over the study period. The Housing First and standard care groups both had decreased use of emergency departments and homeless shelters. The temporal service use changes that occurred as homeless people with mental illness became stably housed are similar for those receiving Housing First or standard care, with the exception of time in prison. Service use patterns, particularly with regard to psychiatric hospitalizations and time in prison, may signify persons who are at-risk of recurrent homelessness. Housing support teams should be alert to the impacts of stay-based services, such as hospitalizations and incarcerations, on housing stability and offer an increased level of support to tenants during critical periods, such as discharges.

Anisotropic yolk/shell or Janus inorganic/polystyrene nanocomposites were prepared by combining miniemulsion polymerization and sol–gel reaction. The morphologies of the anisotropic composites were found to be greatly influenced by surface modification of zinc oxide (ZnO) nanoparticle seeds. Two different types of the oleic acid modified ZnO nanoparticles (OA-ZnO) were prepared by post-treatment of commercial ZnO powder and homemade OA-ZnO nanoparticles. The morphologies and properties of the nanocomposites were investigated by transmission electron microscope (TEM), thermogravimetric analysis (TGA), Fourier transform infrared spectroscopy (FT-IR), dynamic light scattering (DLS), and energy dispersive X-ray spectroscopy (EDX). It was found that both post-treated OA-ZnO and in-situ prepared OA-ZnO nanoparticles resulted in the yolk–shell and Janus structure nanocomposites, but with varied size and morphology. These nanocomposites showed stable and strong fluorescence by introducing quantum dots as the co-seeds. The fluorescent anisotropic nanocomposites were decorated separately with surface carboxyl and hydroxyl groups. These composites with unique anisotropic properties will have high potential in biomedical applications, particularly in bio-detection. - Graphical abstract: Design and development of anisotropic inorganic/polystyrene nanocomposites by surface modification of zinc oxide nanoparticles. - Highlights: • Non-magnetic anisotropic yolk/shell or Janus nanocomposites are prepared and characterized. • Different surface modification of zinc oxide (ZnO) nanoparticles results in varied morphology and size of the final product. • Fluorescent anisotropic nanocomposites embodying quantum dots are an ideal candidate for bio-detection applications.

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

The Crux of Minimalist Architecture: A Local Strategy of Housing Design in Jakarta or a Break Free from Traditions?

Science.gov (United States)

Nurliani Lukito, Yulia; Previta Handoko, Bella

2018-03-01

During the 1950s, the idea of Minimalism presents itself as one of the response of the search of universal language in art and architecture. This particular style, which was started as an art movement, has received many critics in the relation to the loss of art but nevertheless Minimalism has spread all over the world and influenced many disciplines, including architecture. In minimalist architecture, elements of design convey simplicity, basic geometrical forms, with no decoration, and the use of white color, modern materials and clean spaces. The “less is more” movement in architecture, which can be seen in the works of Mies van der Rohe and also in the International Style that celebrates materiality and rationality, is also understood as Minimalism. Moreover, an important historical connection to minimalist architecture is the relationship to popular representations of how the upscale modern family lived. Recently, the idea of minimalist architecture appears in Indonesia as a preferable housing style. Adapting minimalist architecture to be suitable for a tropical climate can be done partly by modifying the forms and the microclimate such as using passive system approach or additional equipment that creates comfort in the building. This paper investigates the idea of minimalist architecture in Jakarta, Indonesia, and how the idea is widely used for housing. Some questions related to this study are investigating whether minimalist architecture in Jakarta shares the same principles with minimalist architecture in its earlier time or it is only a trend in housing design. Not only this study analyzes the moment when the idea of Minimalism develops in the history of modern architecture but also some important characteristics of minimalist architecture in different era and space. In addition, this study also discusses how minimalist architecture that happens in Jakarta becomes a way of dealing with both modern and local conditions, including a break free from

THE HOUSE AS SUPPORT OF GENDER RELATIONS

Directory of Open Access Journals (Sweden)

ANDRA JACOB LARIONESCU

2016-11-01

Full Text Available The article examines the relationship home – gender, using a fieldwork carried out between 2009 and 2011 in the Romanian village of Marginea, a rural community strongly affected by the international migration. I show that migrants from Marginea, even by changing the configuration of their homes, still continue to preserve some old practices related to gender relations such as the responsibility of the man and his family to build the new house or the newlyweds’ settlement in the boy’s house. While home furnishing and decoration are supposed to be performed largely by women, the construction process is related to men. However, today, with the feminization of international labor migration, women are taking a more active role in both house design and construction process.

Adaptive Flight Control Design with Optimal Control Modification on an F-18 Aircraft Model

Science.gov (United States)

Burken, John J.; Nguyen, Nhan T.; Griffin, Brian J.

2010-01-01

In the presence of large uncertainties, a control system needs to be able to adapt rapidly to regain performance. Fast adaptation is referred to as the implementation of adaptive control with a large adaptive gain to reduce the tracking error rapidly; however, a large adaptive gain can lead to high-frequency oscillations which can adversely affect the robustness of an adaptive control law. A new adaptive control modification is presented that can achieve robust adaptation with a large adaptive gain without incurring high-frequency oscillations as with the standard model-reference adaptive control. The modification is based on the minimization of the Y2 norm of the tracking error, which is formulated as an optimal control problem. The optimality condition is used to derive the modification using the gradient method. The optimal control modification results in a stable adaptation and allows a large adaptive gain to be used for better tracking while providing sufficient robustness. A damping term (v) is added in the modification to increase damping as needed. Simulations were conducted on a damaged F-18 aircraft (McDonnell Douglas, now The Boeing Company, Chicago, Illinois) with both the standard baseline dynamic inversion controller and the adaptive optimal control modification technique. The results demonstrate the effectiveness of the proposed modification in tracking a reference model.

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.

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

The aim of this study was to investigate the degree of satisfaction with housing and housing support for people with psychiatric disabilities in Sweden. A total of 370 residents, in supported housing and in ordinary housing with housing support, completed a new questionnaire and reported a high degree of overall satisfaction, but many of them wanted to move somewhere else. Differences were found between the two different types of housing concerning satisfaction with housing support, social life and available choices. Security and privacy, as well as other's influence on the choice of residential area and dwelling proved to be important predictors for satisfaction.

Healthcare providers, such as doctors and nurses, have been famous for high resistance to change. A careful change management plan, particularly training process, is utmost necessary. A quaternary care hospital in India changed its system, from manual to Electronic Medical Record/Health Information System (EMR/HIS). The hospital management wanted to train its 4000 diverse end-users on the EMR/HIS in two months' time. This paper describes an in-house designed training process and its deployment in the given healthcare organizational settings. We designed a training process named DRIPDA. The training process was deployed to train 4000 end-users of EMR/HIS, in the quaternary care hospital. Various factors, such as methods and tools of training, constraints of trainees, trainers, and organization were considered while deploying the training process. The effectiveness of the DRIPDA was assessed using the Kirkpatrick model. End-users received training on the new system only in 25% of estimated time and 28% of the projected expense, without having any distraction in their usual workflow, or any productivity loss. We found that the DRIPDA training process could train all employees effectively and efficiently. A decent training process can help in managing the change, thereby reduce the training time and cost.

Engineerig of structural modifications for operating nuclear plants

Duffy, T.J.; Gazda, P.A.

1983-01-01

The engineering of structural modifications for operating nuclear plants offers many challenges in the areas of scheduling of work, field adjustments, and engineering staff planning. The scheduling of structural modification work for operating nuclear plants is normally closely tied to planned or unplanned outages of the plant. Coordination between the structural engineering effort, the operating plant staff, and the contractor who will be performing the modifications is essential to ensure that all work can be completed within the allotted time. Due to the inaccessibility of areas in operating plants or the short time available to perform the structural engineering in the case of an unscheduled outage, field verification of a design is not always possible prior to initiating the construction of the modification. This requires the structural engineer to work closely with the contractor to promptly resolve problems due to unanticipated interferences or material procurement that may arise during the course of construction. The engineering staff planning for structural modifications at an operating nuclear plant must be flexible enough to permit rapid response to the common 'fire drills', but controlled enough to assure technically correct designs and minimize the expenditure of man-hours and resulting engineering cost.

Choudhary, M.R.; Mustafa, U.S.

2009-01-01

Field tests were conducted to calibrate the existing SCS design equation in determining field border length using field data of different field lengths during 2nd and 3rd irrigations under local conditions. A single ring infiltrometer was used to estimate the water movement into and through the irrigated soil profile and in estimating the coefficients of Kostiakov infiltration function. Measurements of the unit discharge and time of advance were carried out during different irrigations on wheat irrigated fields having clay loam soil. The collected field data were used to calibrate the existing SCS design equation developed by USDA for testing its validity under local field conditions. SCS equation was modified further to improve its applicability. Results from the study revealed that the Kostiakov model over predicted the coefficients, which in turn overestimated the water advance length for boarder in the selected field using existing SCS design equation. However, the calibrated SCS design equation after parametric modification produced more satisfactory results encouraging the scientists to make its use at larger scale. (author)

1989-01-01

The development of structural design tools for Rotary Combustion Engines (RCE) using Finite Element Modeling (FEM) requires knowledge about the response of engine materials to various service conditions. This paper describes experimental work that studied housing deformation as a result of thermal, pressure and mechanical loads. The measurement of thermal loads, clamping pressure, and deformation was accomplished by use of high-temperature strain gauges, thermocouples, and a high speed data acquisition system. FEM models for heat transfer stress analysis of the rotor housing will be verified and refined based on these experimental results.

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

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

2015-01-01

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

Efficient reanalysis of structures by a direct modification method. [local stiffness modifications of large structures

Science.gov (United States)

Raibstein, A. I.; Kalev, I.; Pipano, A.

1976-01-01

A procedure for the local stiffness modifications of large structures is described. It enables structural modifications without an a priori definition of the changes in the original structure and without loss of efficiency due to multiple loading conditions. The solution procedure, implemented in NASTRAN, involved the decomposed stiffness matrix and the displacement vectors of the original structure. It solves the modified structure exactly, irrespective of the magnitude of the stiffness changes. In order to investigate the efficiency of the present procedure and to test its applicability within a design environment, several real and large structures were solved. The results of the efficiency studies indicate that the break-even point of the procedure varies between 8% and 60% stiffness modifications, depending upon the structure's characteristics and the options employed.

Application of the QFD as a design approach to ensure comfort in using hand tools: can the design team complete the House of Quality appropriately?

Science.gov (United States)

Kuijt-Evers, L F M; Morel, K P N; Eikelenberg, N L W; Vink, P

2009-05-01

Quality Function Deployment is proposed as an effective design method to integrate ergonomics needs and comfort into hand tool design because it explicitly addresses the translation of customer needs into engineering characteristics. A crucial step during QFD concerns the linking of engineering characteristics to customer needs in the House of Quality by the design team. It is generally assumed (looking at all the QFD success stories) that design teams can accurately predict the correlations between customer needs and engineering characteristics (also referred to as "Whats"/"Hows" correlations). This paper explicitly tests this assumption by comparing the "Whats"/"Hows" correlations estimated by a design team with those observed in a systematic user evaluation study, which has not been done before. Testing the assumption is important, because inaccurate estimates may lead to ergonomically ineffective (re)design of hand tools and a waste of company resources. Results revealed that the design team's correlation estimates were not as accurate as is generally assumed. Twenty-five percent of the estimates differed significantly with those observed in the user evaluation study. Thus, QFD is a useful method to assist design teams in designing ergonomically more comfortable hand tools, but only on the condition that the correlations between customer needs and engineering characteristics are validated, preferably by means of a systematic user evaluation study.

2017-08-01

The article deals with the effect of a bearing housing on rotor dynamics of a barrel casing centrifugal boiler feed pump rotor. The calculation of the rotor model including the bearing housing has been performed by the method of initial parameters. The calculation of a rotor solid model including the bearing housing has been performed by the finite element method. Results of both calculations highlight the need to add bearing housings into dynamic analyses of the pump rotor. The calculation performed by modern software packages is more a time-taking process, at the same time it is a preferred one due to a graphic editor that is employed for creating a numerical model. When it is necessary to view many variants of design parameters, programs for beam modeling should be used.

The Envirohome: Sustainable housing guidebook and reference manual

Energy Technology Data Exchange (ETDEWEB)

1994-01-01

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

Re-emergence of Indigeneity in transformed Layouts in Urban Public Housing in Nigeria

Directory of Open Access Journals (Sweden)

Abubakar Danladi Isah

2016-01-01

Full Text Available In contrast to the one whole homogenous configuration provided by developers that has often proved ineffective overtime, transformed public housing units are widespread in developing cities. Though transformation is a natural phenomenon of inhabitation, its various levels and degree can have implicit values. In recent times in Nigeria, heterogeneous spatial patterns of transformed houses in public housing estates has given empirical evidence of essentially inevitable reflection of culture sensitivity as hypothesized by previous studies. That hints that the mainstream sustainable values were probably ignored during design process. This study attempted to connect that possible missing link. To achieve that aim, it developed two objectives. First, is to identify core values behind space layouts in the mainstream. Then, to examine how they exist in the transformed layout as reflected at communal origins. It investigated on 42 transformed units in selected urban Public housings neighborhoods via a stratified conditional sampling conducted in five states of Nigeria. Qualitative methods were adopted for data analysis. After identifying the core ethnic groups in the region, their social indicators with regards to space use were determined through ethnographic principles. These indicators were then operationally defined, and used as a tool to examine users’ motivations in the transformation process in urban context. Spatial pattern analysis, by using gamma delineation, revealed the social content in the transformations after comparing initial design and the transformed spatial configurations. The outcome signified the mainstream cultural values in the transformation process hence in Public housing design. The convergence of mainstream values into urban transformed layouts suggested that they cannot be ignored during design process. The outcome of this research might be useful in designing sustainable public housings in culture sensitive environments

A Distributed Sensor Network for the Control of a Bioclimatic House in Spain

2009-10-01

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

New Isues In Singapore Public Housing From Elderly Perspective: case study

Directory of Open Access Journals (Sweden)

Ruzica Bozovic Stamenovic

2012-10-01

Full Text Available This paper examines emerging issues regarding Singapore public housing. With over 80 % of rapidly ageing population living in public housing the elderly perspective is of paramount importance for future development. Following a brief introduction of Housing and Development Board HDB 2 model we are examining new ideas occurring in different scopes and scales, from apartment to urban environment level. Issues like ageing in place, dignity, salutogenesis, active and independent life, image and identification, and other themes pertinent to old age are revisited. Recent issues like high-rise/high-density, consumerism and branding suggest that the usual dogmatic approach to elderly in public housing could be converted to result in creative, affordable, profitable and integrative public housing design.

Do Affordable Housing Projects Harm Suburban Communities? Crime, Property Values, and Taxes in Mount Laurel, NJ.

Albright, Len; Derickson, Elizabeth S; Massey, Douglas S

2013-06-01

This paper offers a mixed-method analysis of the municipal-level consequences of an affordable housing development built in suburban New Jersey. Opponents of affordable housing development often suggest that creating affordable housing will harm surrounding communities. Feared consequences include increases in crime, declining property values, and rising taxes. To evaluate these claims, the paper uses the case of Mt. Laurel, NJ - the site of a landmark affordable housing legal case and subsequent affordable housing development. Employing a multiple time series group control design, we compare crime rates, property values, and property taxes in Mt. Laurel to outcomes in similar nearby municipalities that do not contain comparable affordable housing developments. We find that the opening of the affordable housing development was not associated with trends in crime, property values, or taxes, and discuss management practices and design features that may have mitigated potential negative externalities.

Radon house doctor

International Nuclear Information System (INIS)

Nitschke, I.A.; Brennan, T.; Wadach, J.B.; O'Neil, R.

1986-01-01

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

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

Science.gov (United States)

Dyb, Evelyn

2016-10-01

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

Pre- and post construction radon measurements in a new housing development

2001-01-01

Results from pre- and post construction radon measurements in a new housing development are presented. The houses were built in an area that had not been previously associated with elevated indoor radon concentrations. Exhalation measurements of gravel and stone from the site and soil gas measurements under several houses did not indicate an elevated radon potential. However, 4 of 21 finished houses (or 19%) exhibited annual average indoor radon concentrations over 200 Bq.m -3 (5.4 pCi/l). The highest concentrations were observed in the first house built in 1 of the 6 houses built differently than the original designs, with the elements of a sub floor ventilation system included for possible radon control if necessary. These results suggest that site investigations can be of limited value in determining where not to include radon protection measures in new housing. Also, that care must be taken to adequately inform everyone involved in the building process of the importance of maintaining a tight seal against the ground to prevent possible radon gas entry into a house.

The development of an in-house dispensary in a college health center.

Science.gov (United States)

Nicoteri, Jo Ann L

2016-04-01

A small college health center discovered that students perceived obtaining prescribed medication was a barrier to adherence to short-term antibiotic therapy. To address this specific barrier, an in-house dispensary was developed and modified over the past several years to meet the needs of students. Partnering with a local pharmacy has made the process of obtaining prescriptions easier for the students. Data were extracted from the electronic health records at Student Health Services for the academic year 2014-2015. A total of 910 prescriptions were filled in-house during that time, compared to 102 prescriptions written for purchase elsewhere. Students are utilizing the in-house dispensary more often than taking a prescription to a pharmacy and generally regard the service as convenient. Despite challenges in changing drug prices and other factors that influence medication adherence, dispensing a small number of drugs in the clinic has been feasible and well received. Nurse practitioners must be aware of specific perceived barriers for their practice population and develop interventions to overcome them. The evaluation of such interventions is imperative for modifications and sustainability. ©2016 American Association of Nurse Practitioners.

For the architect is is a constant challeng to deliver architeture and not just buildings. In a foreign context and essential in the developing world housing the urban poor is more about shelter than architecture as such. However even under server economic constraints good design in housing can m...... make a difference. The international organisation Archtecture Sans Frontieres, Denmark has for years been operating in very poor contexts and still in some cases have succeeded to deliver decent and sustainable architecture....

A very limited number of green and sustainable construction studies have explored factors related to Urban Heat Island (UHI) in tropical middle-class housing. This paper aimed to investigate the correlation of Urban Heat Island in tropical middle-class housing in three urban housing for middle-class residents of Palembang, which were Taman Sari Kenten, TOP Jakabaring, and Talang Kelapa. Samples consisted of 125 Taman Sari Kenten housing, 27 Talang Kelapa housing, and 12 TOP Jakabaring housing. Independent variables were the resident density, socioeconomic status, house location, roof type, green area ratio, weather, time, air conditioner, pro-environment institution, and NEP scale. The Analytic method included correlation and regression. We identified that all housing had different UHI profiles where Taman Sari Kenten had the highest UHI (4.17 K), followed by Talang Kelapa (2.66 K) and TOP Jakabaring (0.66 K) against temperature in measuring station nearby, owned by BMKG (National Meteorological Station). UHI correlated with the resident density, roof type, green area ratio, weather, time, and air conditioner. The results should add to the design of ideal housing in the tropical climate for middle-class residents, focusing on its ability to mitigate Urban Heat Island.

House Price, House Quality and Economic Growth

The literature on housing markets suggest that periods of economic growth are characterised by a demand for better housing quality and increasing prices. The basic principles of the theory are that the short-run price fluctuations occur due to market imperfection, while over the long term, causality

Strategies for sustainable households. The SusHouse project

2001-01-01

The international SusHouse project has developed a strategy design approach that can contribute to major (factor 20) efficiency improvements in household activities. Stakeholder workshops have been held to develop scenarios for a sustainable future (2050). These scenarios were evaluated on their economic consequences, environmental impacts and consumer acceptance. the results were then used as the input for a second round of stakeholder workshops, which aimed at developing short-term strategies and implementation plans. This Research Note reviews the SusHouse approach and its results. It ends with suggestions for further steps to be taken. A SusHouse CD-ROM is available, containing all final project reports as well as a scenario presentation in the form of images and short texts. 22 refs

The CRISPR/Cas9 system is a powerful tool for precision genome editing. The ability to accurately modify genomic DNA in situ with single nucleotide precision opens up new possibilities for not only basic research but also biotechnology applications and clinical translation. In this chapter, we outline the procedures for design, screening, and validation of CRISPR/Cas9 systems for targeted modification of coding sequences in the human genome and how to perform genome editing in induced pluripotent stem cells with high efficiency and specificity.

Theoretical overview of heating power and necessary heating supply temperatures in typical Danish single-family houses from the 1900s

in typical Danish single-family houses constructed in the 1900s. The study provides a simplified theoretical overview of typical building constructions and standards for the calculation of design heat loss and design heating power in Denmark in the 1900s. The heating power and heating demand in six typical...... Danish single-family houses constructed in the 1900s were estimated based on simple steady-state calculations. We found that the radiators in existing single-family houses should not necessarilrbe expected to be over-dimensioned compared to current design heat loss. However, there is considerable...... potential for using low-temperature space heating in existing single-family houses in typical operation conditions. Older houses were not always found to require higher heating system temperatures than newer houses. We found that when these houses have gone through reasonable energy renovations, most...
