    The pilot project, named Comfort Houses, aims to show the industry that it is possible to construct traditional Danish houses as passive houses and promote them as comfortable houses. For this to be a success in the future, it is necessary to fulfil the occupants’ wants and needs. This study aims...... to communicate how the occupants of the Comfort Houses experience living in a passive house and illustrate how their behaviour affect the performance of the house. This is done through qualitative interviews with the occupants compared with quantitative measurements of the performance of the Comfort Houses....... A total of 3 residential units have been examined and the results show that the occupants’ everyday lives have changed – some as a result of the architectural and structural solutions, others as a result of the technology integrated in the houses. The study determines the importance of considering...

    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

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

    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.

  8. Passive houses in Norway

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

    The 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.

    The purpose of this study was to evaluate the indoor air quality (IAQ) in newly built low energy houses. Measurements were performed in 22 passive houses and 21 conventional buildings during 2012-2013 and 2013-2014 heating seasons. The measured parameters were temperature, relative humidity......, concentration of CO2, NO2, formaldehyde, volatile organic compounds, and live microbiological flora. Air exchange rates (AER) were determined from the concentration-time profiles of CO2. The median AER was slightly higher in the passive houses than in conventional buildings (0.66 h-1 vs. 0.60 h-1). The median...... concentrations in passive houses and conventional buildings were 9.7 and 11 μg/m3, respectively, for NO2, 12 and 16 μg/m3 for formaldehyde, and 230 and 145 μg/m3 for TVOC.

    In 2012-2013, IBACOS worked with a builder, Brookfield Homes in Denver, Colorado, to design and construct a Passive House certified model home. 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.

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

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

    2008-05-15

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

    Mølhave, L.; Schneider, T.; Kjærgaard, S. K.; Larsen, L.; Norn, S.; Jørgensen, O.

    Floor dust from Danish offices was collected and analyzed. The dust was to be used in an exposure experiment. The dust was analyzed to show the composition of the dust which can be a source of airborne dust indoors. About 11 kg of dust from vacuum cleaner bags from seven Danish office buildings with about 1047 occupants (12 751 m 2) was processed according to a standardized procedure yielding 5.5 kg of processed bulk dust. The bulk dust contained 130.000-160.000 CFU g -1 microorganisms and 71.000-90.000 CFU g -1 microfungi. The content of culturable microfungi was 65-123 CFU 30 g -1 dust. The content of endotoxins ranged from 5.06-7.24 EU g -1 (1.45 ng g -1 to 1.01 ng g -1). Allergens (ng g -1) were from 147-159 (Mite), 395-746 (dog) and 103-330 (cat). The macro molecular organic compounds (the MOD-content) varied from 7.8-9.8 mg g -1. The threshold of release of histamine from basophil leukocytes provoked by the bulk dust was between 0.3 and 1.0 mg ml -1. The water content was 2% (WGT) and the organic fraction 33%. 6.5-5.9% (dry) was water soluble. The fiber content was less than 0.2-1.5% (WGT) and the desorbable VOCs was 176-319 μg g -1. Most of the VOC were aldehydes. However, softeners for plastic (DBP and DEHP) were present. The chemical composition includes human and animal skin fragments, paper fibers, glass wool, wood and textilefibers and inorganic and metal particles. The sizes ranged from 0.001-1 mm and the average specific density was 1.0 g m -3. The bulk dust was resuspended and injected into an exposure chamber. The airborne dust was sampled and analyzed to illustrate the exposures that can result from sedimented dirt and dust. The airborne dust resulting from the bulk dust reached concentrations ranging from 0.26-0.75 mg m -3 in average contained 300-170 CFU m -3. The organic fraction was from 55-70% and the water content about 2.5% (WGT). The content of the dust was compared to the similar results reported in the literature and its toxic potency is

    The report is prepared in relation to the project ''demonstration of energy consumption and indoor climate in 10 Danish passive houses'' which was carried out from 2008 to 2012 in the Comfort Houses. The report presents the achieved results based on measurements of indoor climate and energy consumption, and it also suggests viable solutions for the future low-energy buildings. The Comfort House project was started in 2007 as a development project at the company Saint Gobain Isover A/S, who wanted to disseminate knowledge about low-energy buildings and the principles behind them. The present report mainly focuses on the results from the Comfort Houses, but it also includes references to other Danish experimental buildings and development projects. Furthermore, the analyses are supplemented with experiences from Swedish low-energy buildings found through literature reviews. The indoor climate analyses deal with the different physical parameters that impact the residents. The evaluation includes both thermal, atmospheric, daylight and acoustic climate. The energy consumption is evaluated together with some of the key parameters from the houses that are related to the energy consumption. Finally, the residents' behaviour impacting both energy consumption and indoor climate are analysed. (LN)

    The new Danish Building Regulations (Building Regulations, 2005) introduces the total energy consumption, i.e. energy use for heating, ventilation, cooling and domestic hot water, for buildings as a measure for the energy efficiency of new buildings, i.e. moving away from the former U-value demands....... In addition to the minimum requirements for new buildings, the new Building Regulations also specify requirements for characterizing a building as either low energy building class 1 or low energy building class 2. This paper describes a type-house that is presently being built in Denmark. The type......-house easily meets the requirements for being categorized as a low energy building class 1, and the paper investigates how much U-values can be increased if the type-house were to fulfil the requirements for a low energy building class 2 or a building that just fulfils the minimum demands....

  4. Passive energy standard in building as a perspective of sustainable development - first passive houses in Croatia

    International Nuclear Information System (INIS)

    Miscevic, Lj.

    2005-01-01

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

    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

    1983-11-01

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

    As a prelude to a nationwide survey a pilot study was carried out to establish techniques and procedures for the measurement of indoor radiation in Denmark. A passive cup dosemeter was designed containing CR39 track detectors and TLD's to measure radon and external radiation, respectively. The adequate performance of the dosemeter was verified in a radon intercalibration in 1984 carried out at the National Radiological Protection Board, UK. A total of 82 dwellings were selected covering most regions of the country. The dwellings were monitored in two three-month periods, one in winter and the other in summer. The average dose rate in air from external radiation was 0.09 μGy h -1 . In the winter the average radon concentrations were 88 Bq m -3 and 24 Bq m -3 for single-family houses and flats, respectively; and in the summer the corresponding values were 52 Bq m -3 and 19 Bq m -3 .

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

    A passive house is a cost-efficient building that can manage throughout the heating period, due to its specific construction design, with more than 10 times less heat energy than the same building designed to standards presently applicable across Europe. Its extended thermal insulation and enhanced air-tightness removes the need for temperatures higher than 50 {sup o}C. This makes renewable energy sources particularly suitable for heating, cooling and domestic hot water production. Modeling of renewable energy usage for space heating requires as a preliminary stage the detailed description of the building structure, of the HVAC equipment and of the internal heat sources. This paper shows the main data used to model the thermal behavior of a passive house. Details about Pirmasens Passive House (Rhineland Palatinate, Germany) are given, as for example, the internal heat sources, including electric appliances, heat and humidity released by human bodies, thermal internal facilities as hot and cold water pipes. All these are quantified by using statistically derived data. A detailed time schedule for a standard German family with two adults and two children was prepared. It takes into account the national celebrations, vacation and weekends among others. (Author)

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

    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

    Directory of Open Access Journals (Sweden)

    Andreas Hetland

    2017-09-01

    Full Text Available The primary contribution of this paper is to establish that the long-swings behavior observed in the market price of Danish housing since the 1970s can be understood by studying the interplay between short-term expectation formation and long-run equilibrium conditions. We introduce an asset market model for housing based on uncertainty rather than risk, which under mild assumptions allows for other forms of forecasting behavior than rational expectations. We test the theory via an I(2 cointegrated VAR model and find that the long-run equilibrium for the housing price corresponds closely to the predictions from the theoretical framework. Additionally, we corroborate previous findings that housing markets are well characterized by short-term momentum forecasting behavior. Our conclusions have wider relevance, since housing prices play a role in the wider Danish economy, and other developed economies, through wealth effects.

    2013-12-01

    Full Text Available he topic researched within the applied project. "Safety of passive houses subjected to earthquake" stemmed from two otherwise quite unrelated fields, i.e. seismic resistance and energy efficiency that in European countries do not frequently appear together. Just in Slovenia these two fields join each other, so identifying the problem and establishment of research right in Slovenia represents uniqueness and specificity. The majority of Slovenia is situated in area of moderate seismic risk. In order to ensure adequate mechanical resistance and stability of structures constructed in such area, the consideration of seismic effects is required by law. In Slovenia the number of passive houses and energy efficient buildings increases rapidly. However, for the time being the structural solutions that have been developed and broadly applied mainly in the areas with low seismicity (where the structural control to vertical static loads is sufficient are used. In earthquake-prone areas also adequate resistance to dynamic seismic effects have to be assured.

    from 2003 to 2006. The activity in the construction sector has been increasing too, but with some time lag caused by what seems to be an inelastic supply. In the long run, house prices will be determined by the replacement cost of houses, e.g. the cost of constructing a similar house including the cost...... of land.

    The term "passive house" refers to rigorous and voluntary standards for energy efficiency in a building, reducing its ecological footprint. There are many ways how to build a passive house successfully. These designs as well as construction techniques vary from ordinary timber constructions using packs of straw or constructions of clay. This paper aims to quantify environmental quality of external walls in a passive house, which are made of a timber frame, lightweight concrete blocks and sand-lime bricks in order to determine whether this constructional form provides improved environmental performance. Furthermore, this paper assesses potential benefit of energy savings at heating of houses in which their external walls are made of these three material alternatives. A two storey residential passive house, with floorage of 170.6 m2, was evaluated. Some measurements of air and surface temperatures were done as a calibration etalon for a method of simulation.

    The adverse effects of air pollution on health have been recognised for millennia, but only in recent centuries they have been directly documented. In this paper evidence of the levels of exposure in the Danish Iron Age has been obtained from real measurements. The personal exposure to NO 2 was measured over one week from 6 to 13 February 1999 for a person living in a reconstructed house from the Danish Iron Age (500 BC-700 AD). At the same time NO 2 was measured close to the fireplace and next to the beds as well as outdoor at a distance of about 20 m from the house. Finally, 1 h average concentrations of benzene were measured for a 24 h period during the exposure measurement. A weekly average exposure of NO 2 was measured to be 61.6 μg N m -3. In the house as high as 110.8 μg N m -3 weekly average was measured for NO 2 and a 24 h average value of 45.8 μg m -3 was determined for benzene. The exposure is compared with the present levels.

    The report is prepared in relation to the project ''demonstration of energy consumption and indoor climate in 10 Danish passive houses'' which was carried out from 2008 to 2012 in the Comfort Houses. The report presents the achieved results based on measurements of indoor climate and energy consumption, and it also suggests viable solutions for the future low-energy buildings. The Comfort House project was started in 2007 as a development project at the company Saint Gobain Isover A/S, who wanted to disseminate knowledge about low-energy buildings and the principles behind them. The present report mainly focuses on the results from the Comfort Houses, but it also includes references to other Danish experimental buildings and development projects. Furthermore, the analyses are supplemented with experiences from Swedish low-energy buildings found through literature reviews. The indoor climate analyses deal with the different physical parameters that impact the residents. The evaluation includes both thermal, atmospheric, daylight and acoustic climate. The energy consumption is evaluated together with some of the key parameters from the houses that are related to the energy consumption. Finally, the residents' behaviour impacting both energy consumption and indoor climate are analysed. (LN)

  7. A comprehensive assessment of the life cycle energy demand of passive houses

    International Nuclear Information System (INIS)

    Stephan, André; Crawford, Robert H.; Myttenaere, Kristel de

    2013-01-01

    Highlights: • The life cycle energy demand of a passive house (PH) is measured over 100 years. • Embodied, operational and user transport energy demand are considered. • Embodied energy represents the highest energy consumption in all variations. • A PH might not save energy compared to a standard house. • A poorly insulated city apartment can use less energy than a best case suburban PH. - Abstract: Certifications such as the Passive House aim to reduce the final space heating energy demand of residential buildings. The latter are responsible for a significant share of final energy consumption in Europe of which nearly 70% is associated with space conditioning, notably heating. The improvement of the energy efficiency of residential buildings, in terms of space heating, can therefore reduce their total energy demand. However, most certifications totally overlook other energy requirements associated with residential buildings. Studies on passive houses do not take into consideration the embodied energy required to manufacture the building materials, especially the large amount of insulation required to achieve high operational efficiencies. At an urban scale, most passive houses are single family detached houses located in low density suburbs with a high car usage, resulting in considerable transport related energy demand. This paper analyses the total life cycle energy demand of a typical Belgian passive house, comprising embodied, operational and transport energy. It relies on a comprehensive technique developed by Stephan et al. [1] and conducts a parametric analysis as well as a comparison to alternative building types. Results show that current building energy efficiency certifications might not ensure a lower energy demand and can, paradoxically result in an increased energy consumption because of their limited scope. More comprehensive system boundaries should be used to make sure that net energy savings do occur. The embodied energy of passive

  9. Household air pollution from wood burning in two reconstructed houses from the Danish Viking Age.

    Christensen, J M; Ryhl-Svendsen, M

    2015-06-01

    During 13 winter weeks, an experimental archeology project was undertaken in two Danish reconstructed Viking Age houses with indoor open fireplaces. Volunteers inhabited the houses under living conditions similar to those of the Viking Age, including cooking and heating by wood fire. Carbon monoxide (CO) and particulate matter (PM2.5 ) were measured at varying distances to the fireplace. Near the fireplaces CO (mean) was 16 ppm. PM2.5 (mean) was 3.40 mg/m(3) , however, measured in one house only. The CO:PM mass ratio was found to increase from 6.4 to 22 when increasing the distance to the fire. Two persons carried CO sensors. Average personal exposure was 6.9 ppm, and from this, a personal PM2.5 exposure of 0.41 mg/m(3) was estimated. The levels found here were higher than reported from modern studies conducted in dwellings using biomass for cooking and heating. While this may be due to the Viking house design, the volunteer's lack of training in attending a fire maybe also played a role. Even so, when comparing to today's issues arising from the use of open fires, it must be assumed that also during the Viking Age, the exposure to woodsmoke was a contributing factor to health problems. © 2014 John Wiley & Sons A/S.

    This study examines the potential of implementing the passive house standards to reduce energy consumption on school buildings in Brunei. Furthermore, it investigates whether sustainable school buildings make business sense to the government. To do this, conventional and Passive House primary school buildings are compared in terms of their performances using the Passive House Planning Package as well as the Ecotect environmental analysis tool. The findings indicated that by replacing lower U-values building fabrics brought a significantly reduction in the cooling demand of 54%. Whereas, Ecotect models have demonstrated that the heating and cooling loads have tremendously reduced to 75% by reorienting the location of the building to south elevation and by replacing the building fabrics with a lower U-values. These findings were then evaluated with a cost benefit analysis that proved to save cost energy annually from air-conditioning usage from a typical primary school with eight years of pay back period.

    `Passive` houses, i.e. houses without active heating, are extremely energy-optimized houses: thanks to their efficient thermal protection, their heat demand falls below the threshold requiring a separate space heat distribution system (15 kWh/(m{sup 2}a)). Passive houses will account for an increasing proportion of new buildings already during the next years. Houses with zero thermal energy demand involve notably higher construction effort but do not contribute essentially more to the mitigation of environmental pollution. (orig.)

    This paper looks through the many benefits of earth not only as a building element in its natural form but as a building mass, energy pack and spatial enclosure which characterized by location, unique physical terrain and climatic factors can be utilized in developing housing units that will provide the needed benefits of comfort alongside the seasons. Firstly the study identifies existing sunken earth houses in the North-west of China together with identifying the characters that formed the ideas behind the choice of going below the ground. Secondly, the study examines the pattern of heat exchange, heat gains and losses as to identify the principles that makes building in earth significant as an energy conservation system. The objective of this, is to relate the ideas of sunken earth home design with such principles as the passive annual heat storage systems (PAHS) in producing houses that will serve as units used to collect free solar heat all summer and cools passively while heating the earth around it and also keeping warm in winter by retrieving heat from the soil while utilizing the free solar heat stored throughout the summer as a year-round natural thermal resource.

    The energy requirements for a passive house are quite strict. These requirements need to be adopted already in early phase of project planning. Collaboration between different design domains is a necessity. System design requires accurate information on the performance parameters of equipment. This information has to be available for the designers. Paroc passive house shows that HVAC system settings and trimming are a condition of the required performance. System adjustments and trimming were carried out almost for one year after the building was finished. The need for adjustments comes from poor documentation of the performance parameters of the equipment. Accurate monitoring results are available for less than one year; however, the results show that the building meets the requirements set on the delivered energy and primary energy. The primary energy use in the two apartments is 96 and 130 kWh/m{sup 2}. The airtightness of the building envelope were n{sub 50} = 0.37 1/h and n{sub 50} = 0.25 1/h correspondingly. The primary energy use in the passive house Paroc Lupaus is 130 kWh/m{sup 2} and the airtightness of the building envelope n{sub 50} = 0.5 1/h. The energy used for space heating 30 kWh/m{sup 2} exceeds the set requirement of 25 kWh/m{sup 2}. The indoor temperature has been higher than assumed in the design. The monitoring shows that the technical systems do not perform as expected. There is still need for adjustments and trimming both for the ventilation system and heat pump. In general, the performance parameters of the HVAC systems are not accurate enough for passive house design. (orig.)

    Full Text Available Two eight-story wood-framed residential buildings with the Swedish 2012 passive house standard were built in 2009 in the Portvakten Söder quarter in the city of Växjö in Sweden. In this paper, we present the monitored specific energy use of the buildings and compare to the requirements of the Swedish building code and recommendation for passive houses. We also estimated the primary energy use and CO2 emissions and investigated the tenants’ views and experiences of the two buildings. Results show that the actual specific energy use of 40.2 kWh/m2Atemp/year in the Portvakten Söder building fulfills, by a good margin, the requirements of the Swedish building code and the recommended passive house standard, but is higher than projected. Applying a marginal perspective, the calculated primary energy use and carbon dioxide emission from operating the buildings (excluding household electricity was 40 kWh/m2Atemp/year and zero, respectively. Responses of 20 tenants to a mail-in questionnaire survey showed that over 90% were satisfied with their apartments.

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

    2016-03-01

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

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

    2006-01-01

    Passive houses offer extended living comfort with only 15-20% of the space heating demand of conventional new buildings while the extra costs of this standard are only about 10% of the total building costs. In the first part of this paper, detailed measurements for 11 'Passive House' projects with more than 100 dwelling units from the EU-funded demonstration project CEPHEUS (Cost Efficient Passive Houses as EUropean Standards) are presented. All projects exhibit extraordinarily low space heat consumptions. Compared with ordinary, newly erected buildings, 80% of the space heat consumption could be saved. The total primary energy consumption (including household electricity) was less than 50% of that of conventional new buildings. The measurements show that the buildings also offer comfortable indoor conditions in both summer and winter. Several social research studies revealed that the users are well pleased with their homes. The second part of the paper focuses on low-income tenant's satisfaction in the world's first multi-story Passive Houses in Kassel, Germany. This building contrasts sharply with the 'standard' Passive House, occupied by its owners. A 2.5 year study was conducted from spring of 2000 to autumn of 2002. The development of opinions, attitudes, behaviour, and satisfaction over time could be recorded. The building is a clear success, the tenant's satisfaction is high. It is concluded that this building type fulfils the conditions of sustainability in social, ecological and economic respects and should therefore be disseminated on a larger scale. To this end, the last part of the paper describes the development of the Passive House standard in Germany, Austria and Switzerland, from the first demonstration project in 1991 to about 3500 dwelling units today. The prerequisites for this development are analysed. Finally, the authors give their view about the political possibilities for pushing Passive Houses into the market as well as for stimulating a

    2016-01-01

    Full Text Available Using renewable energy is becoming more profitable nowadays because of applying advanced technology. The paper, presented by the authors, analyses the case of using solar and geothermal energy to create comfort in homes with low energy consumption. In this situation, the performance of the systems that take energy from low-heat renewable sources and convert it into useful energy is growing. The characteristics of the buildings with low power consumption, of passive houses in particular, can cause the development of a new generation of devices to create comfort. The energy used to create comfort in the first passive house built in Romania, which was designed for offices, analyzed by the authors, is using both geothermal and solar power. The authors present the energy performance of the building correlated with the performance of the air-conditioning system that uses ground-water heat pumps. The thermodynamic analysis presented, highlights how the performance of geothermal energy systems increased, their variation depending on the climate zone variation parameter values. The authors make a detailed analysis, in the presented paper, about the influence of the working conditions of the installation elements, on the heat pump energy consumption and the methods adopted to reduce losses and increase system performance.

    2018-06-01

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

    Solar radiation is the primary source of life energy on Earth. The irradiance of the upper atmosphere is about 1360 W/m2, and it is estimated that about 1000 W/m2 reaches the ground. Long-term storage of heat energy is related to the use of a suitable thermal energy carrier. It may be either artificial or natural water tank, or artificial gravel-water tank, or aquifer or soil. It is justified to store the generated energy in large heating systems due to the nature of solar thermal energy. Typically, in such a solution storage space is a large solar collector farm. The reason for this is the proportionally small unit profits, which only in the case of large number of units provides sufficient energy that can be accumulated. It should be noted that Poland, a country located in a temperate and less harsh climate such as Scandinavia and Canada, has a relatively high potential for solar revenue. In the last decade, it has caused mainly small and individual heating installations. However, much of the municipal and industrial economy continues to rely on energy from non-renewable resources. This is due not only to the lack of a high-efficiency alternative to non-renewable energy resources, but also to the thermal state of buildings throughout the country, where old buildings require thermomodernization. This has the effect of both polluting the environment and the occurrence of smog, as well as pollutants in water and soil. This directly affects the occurrence of civilization diseases and other societal health problems. Therefore, the surplus of thermal clean energy that occurs during the spring and summer period should not only be used on a regular basis, but also stored for later winter use. The paper presents the concept of housing estate, which consists of 32 twin housing units. The solid character of buildings consistently refers to passive construction, and the materials meet the requirements for the passive buildings.

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

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

    2015-01-01

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

  2. Passive House and Low Energy Buildings: Barriers and Opportunities for Future Development within UK Practice

    Directory of Open Access Journals (Sweden)

    Adrian Pitts

    2017-02-01

    Full Text Available This paper describes research carried out to understand better the current and future emphases emerging from practice for the design and development of “Passive House” and low energy buildings. The paper initially discusses the extant position, particularly with regards to the UK and considers how regulation and assessment systems have changed in recent years, as well as projecting ideas forward taking account of contemporary political situations. Relevant previous research into Passive House and low energy design and construction is then reviewed. The need for greater understanding of professionals and their communication/collaboration with clients were identified as important factors impacting development. Those involved in the design and construction practice therefore have key roles in the process of enhancing energy efficiency. Five industry/practice based professional organizations were interviewed in-depth to gain insights into their experience of current low energy design, and to extrapolate the outcomes to future scenarios. The method employed used a structured interview technique with key question areas to lead the discussion. The anonymized responses discussed are grouped around key themes. Evidence suggests there has been a move towards the adoption of voluntary high level standards because of potential limitations with mandatory regulations and because of perceived additional benefits of higher quality design. This change is now more than previously, being driven by informed clients, design professionals, and the industry, with regulation taking a secondary role. New opportunities and barriers are becoming evident and these require further consideration.

    Built environmental attributes have been studied in relation to domestic time spent sedentary. An indoor behaviour has thus been linked to an outdoor setting. Yet, attributes of the actual domestic environment may also influence the time spent sedentary at home. Therefore, the aim was to examine if housing characteristics were cross-sectionally and prospectively related to leisure-time sitting in adults. In the Danish Health2006 cohort, 2308 adults were followed for 5 years. At baseline, subjects self-reported housing characteristics (habitat type, habitat surface area and household size), moderate-to-vigorous physical activity (MVPA) and socio-demographic factors. Leisure-time sitting was self-reported at baseline and 5-year follow-up. Multiple linear regression was used to assess cross-sectional and prospective associations. At baseline habitat surface area and household size were inversely associated with leisure-time sitting (pleisure-time sitting compared to living in a house (pleisure-time sitting (pleisure-time sitting in adults, while especially household size was a predictor of leisure-time sitting five years later. The findings highlight the importance of home-environmental attributes when targeting a reduction in sedentary behaviours. Copyright © 2015 Elsevier Inc. All rights reserved.

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

    Energy and climate are key issues, but sustainable architecture involves much more: nature's cycles, materials, resilience over time, health. The trend towards passive house standard is positive, but tends to become dogmatic and far too narrowly focused on energy - and on theory rather than on real people. Buildings should be healthy, both for people and for the planet. Without a holistic approach, passive houses can introduce new risks, both technical, inefficient use of money, and risks to indoor environment. And if built in energy-intensive materials transported from far away, they can have just as large climate emissions as old buildings. Researchers, argue the authors, sometimes ignore the human ecological dimensions of sustainability, in their obsession with technical details. This book raises two types of critique of the passive house concept: one concerns technical differences, in particular a very sceptical look at mechanical ventilation; the other relates to people. For it is not only immigrants or the elderly who often fail to maintain buildings correctly, but many ordinary people too. Passive houses must be built with a high degree of precision, and operated correctly. In addition, builders often make errors; and technology fails quite often. In contrast to this, older buildings are 'forgiving' - they tolerate small leaks, amateur repairs, minor neglect. Simplicity is a key feature of good solutions. The authors argue that sustainable architecture must have real robustness. For sustainability depends on ordinary, fallible people. Beginning with a short history of ecological or 'green' architecture, and of the principles behind it, the book reminds us that the first houses to achieve passive standard were built and tested in Canada over 30 years ago. The book is illustrated with 14 buildings from Norway and Europe, many of them groundbreaking; about half are signed by the GAIA network of architects. These include houses designed

    There is a great need for upgrading and thermo-modernisation of a large part of the Polish housing stock. In this report the focus is concentrated on upgrading and thermo-renovation of buildings constructed in the 1950`s to the 1970`s. These buildings are characterised by extensive use of prefabricated concrete panels in the facades or massive brick walls. Great numbers of this type of residential building are situated all over Poland. The implementation of energy saving measures - such as installation of modern automation and control equipment and applying external thermal insulation - will result in a number of ecological, social and economic benefits: Reduction in air pollution; Reduction of future increases for cost of household energy consumtion; A convincing improvement of the indoor climate; Creation of an extended market basis for development of a Polish industry supplying, installing and maintaining energy efficient building components. In order to illustrate these benefits for the owners and the tenants the Danish Ministry of Housing and Urban Planning offered to participate in three demonstration projects: Na Skraju Housing Cooperaive, Warsaw. The project focuses on the use of fire-safe, stable and affordable external insulation on a 5-storey housing block and the introduction of a contemporary energy management system. A demonstration building has been insulated, the sub-station has been upgraded to modern standards for energy management. New and much smaller radiators fitted with thermostatic valves and corresponding to the reduced energy requirements have been installed. Heat allocation meters are fitted to the radiators. All piping for space heating and water has been replaced. Energy consumption and indoor climate is now monitored and compared to the results from a neighbouring reference block; Zarzad Budynkow Komunalnych, Warszawa. The project includes the total insulation of facades and roofs as well as replacement of interior piping for heaitng

    In the examined Swiss 'passive' houses the ambient air temperatures in the winter season are markedly higher than 20 {sup o}C, in the summer season they are mostly under 26 {sup o}C and the values for relative humidity in winter are frequently under 30 % r.h. With one exception the requirement of the passive house standard to primary energy consumption (120 kWh/m{sup 2} year) is reached or undercut scarcely. The requirement to yearly heating energy consumption cannot to be kept (15 kWh/m{sup 2} year) and this in part clearly (+150 %). About 35 % of the total heat energy is used for domestic hot water. The measured values for energy consumption were mostly higher than predicted (30 to 300 %). The number and presence of occupants was overestimated by planners. The effective number of occupants per household is about the same as the mean value for Switzerland (2.3 persons per household). Air tightness of the envelope is unexpectedly bad and reaches n{sub 50}- values from 0.9 to 2.5 h{sup -1}. The mean value of the specific household electricity consumption is 25.9 kWh/m{sup 2} year, which is markedly higher than the Minergie{sup R}-P standard (17 kWh/m{sup 2} year) but lower than the SIA 380/1 value (27.8 kWh/m{sup 2} year). The specific electricity consumption for ventilation is higher than the one of comparable Minergie{sup R} buildings because of pressure losses due to air heating components and higher outside air volume flow rates. With one exception the target and threshold values for the specific electricity consumption of the air delivery of the SIA Technical Documentation 2023 could not be achieved. In two cases it was possible to reduce the electricity consumption for ventilation by the installation of better ventilation drives (-38 %) or by the reduction of the outside air volume flow rate (-22 %).

  4. 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.

    This extensive report for the Swiss Federal Office of Energy (SFOE) presents the results of a project concerning so-called 'passive' houses which exhibit extremely low energy consumption. The authors state that the findings also apply to the Swiss 'Minergie-P' standard. The aims of the project are quoted, including ways of simplifying the air distribution system, possibilities of using air-based heating systems for non-passive housing, how the building's mass can be used as a heat exchanger and for heat storage and what requirements are to be placed on the small wood-fired ovens often found in such houses. Topics discussed include temperatures and temperature gradients, thermal comfort, draught risks and air-flow rates. Further, questions concerning heat-distribution and control systems, fire and noise protection and humidity are discussed, as are heat losses and gains. Examples of dwellings being examined as part of pilot and demonstration projects are given.

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

    With the coming shortage of fossil fuels, it is important to develop innovative techniques that reduce both energy consumption and pollution at the same time. In Algeria, the residential sector is the highest energy consumer, accounting for 41% of the country's total consumption; this must be reduced. The aim of this study is to analyze the energy use of dwellings and find solutions to reduce it. The analysis was performed on a 100m2 plate surface house situated in Tlemcen conceived in R+2 stages. In addition, an ecological design was developed and analyzed to determine the savings which could be made. Results showed that significant reduction of energy use and environmental impacts can be achieved through an ecological design. This study demonstrated that the concept of the ecological house can be applied to Mediterranean climate regions and would result in better energy and environmental performance as well as cost savings over the years.

    Full Text Available OBJECTIVES: Sex differences in occupational biomechanical exposures may be part of the explanation why musculoskeletal complaints and disorders tend to be more common among women than among men. We aimed to determine possible sex differences in task distribution and task-specific postures and movements of the upper extremities among Danish house painters, and to establish sex-specific task exposure matrices. METHODS: To obtain task distributions, we sent out a questionnaire to all members of the Painters' Union in Denmark (N = 9364, of whom 53% responded. Respondents reported their task distributions in a typical week. To obtain task exposures, postures and movements were measured in 25 male and 25 female house painters for one whole working day per person. We used goniometers on the wrists, and inclinometers on the forehead and the upper arms. Participants filled in a logbook allowing task-specific exposures to be identified. Percentiles and % time with non-neutral postures were used to characterise postures. Velocity, range of motion, repetitiveness, and variation were used as measures of movement. Cochran-Mantel-Haenszel statistics and unpaired double-sided t-tests with post-hoc Bonferroni correction were used to evaluate sex differences. RESULTS: Statistically significant (p<0.05 sex differences were revealed in task proportions, but the proportions differed by less than 4%. For task exposures, no statistically significant sex differences were found. CONCLUSIONS: Only minor sex differences were found in task distribution and task exposures regarding postures and movements among Danish house painters. Sex-specific task exposure matrices were established.

  20. Passive House at the crossroads: The past and the present of a voluntary standard that managed to bridge the energy efficiency gap

    2013-01-01

    Improving energy efficiency in dwellings is generally seen as the low-hanging fruit of climate change mitigation. In particular decreased heat loss through better insulation is suggested as one of the most cost-effective means to achieve the ambitious national and international goals of climate gas reduction. However, the literature shows that a profitable technological solution is not sufficient to reach the energy goals. Aspects such as a lack of information, unobserved costs, and heterogeneity among users can compromise the success of technical innovation. Still, there are successful concepts that drive the technological development in the construction sector. The Passive House is an example for such innovations that manage to bridge the energy efficiency gap. This paper addresses the Passive House concept and standard as a success story of technological innovation. With Bruno Latour's Science in Action (1987) as a starting point, we describe the conditions under which the standard was created, the role of the network built around the Passive House Institute, and the consequences of exporting the standard. We identify success factors that have supported the diffusion of the Passive House standard and concept and discuss its possible development in the current situation which is characterized by its wide-spread adoption. - Highlights: • We present the Passive House (PH) as example of technological innovation. • The developers of PH managed to overcome the barriers to energy efficiency. • Successful innovation is more than good technology. • The heterogeneity of adopters of PH is growing. • The future of PH: the tension between rigid control and flexible adaptability

  1. Environmental and economic performance of heating systems for energy-efficient dwellings: Case of passive and low-energy single-family houses

    2012-01-01

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

    Experience and evaluation of ten-year-old passive houses - indoor environment, durability and user convenience Although many passive houses and low-energy houses were evaluated while they were still newly built, there has not been much evaluation of them after several years' of occupation. This indicates a need to re-visit older passive houses in order to pick up any aspects that could be improved in the interests of operating aspects, good indoor environmental conditions, moisture safety or continued low energy use. The objective of this project has been to provide the building sector with feedback of experience from the first passive houses in Sweden, which were first occupied in 2001. User experiences have been collected through interviews, and indoor environmental conditions and the performance of technical systems have been monitored and measured. Energy use data for the houses has also been obtained. The work has been carried out on ten of the twenty terrace house units that were built outside Goeteborg. As the houses were thoroughly monitored while they were new, we can see if and how they have changed over their first ten years' occupation. The results shows that, in general, the occupants are very satisfied, although they have put forward proposals for certain improvements, linked to the fact that it is they themselves who operate and look after the houses. Similarly, measurement and monitoring of the indoor conditions and the technical systems shows that, in many respects, the houses have aged well, although there is also scope for improvement in order to ensure that the initially low energy consumption does not tend to increase, and to maintain the good indoor environmental conditions. Interviews, follow-up of energy use and measurements of indoor conditions and the performance of technical systems have included indoor thermal conditions, solar collector systems, performance of heat exchangers, air flows, acoustic conditions, airtightness of

    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.

    Full Text Available This paper presents energy and environmental performance analyses, a study of summer indoor temperatures and occupant behavior for an eight story apartment building, with the goal to combine high energy efficiency with low environmental impact, at a reasonable cost. Southern Portvakten building is built with prefabricated timber elements using passive house principles in the North European climate. Energy performance was analyzed through parametric studies, as well as monitored energy data, and complemented with analysis of occupant behavior during one year. Results show that airtight, low-energy apartment buildings can be successfully built with prefabricated timber elements in a cold climate. The monitored total energy use was 47.6 kWh/m2, excluding household electricity (revised to a normal year, which is considerably lower than of a standard building built today in Sweden—90 kWh/m2. However, the occupancy level was low during the analyzed year, which affects the energy use compared to if the building had been fully occupied. Environmental analysis shows that the future challenges lie in lowering the household and common electricity use, as well as in improving the choices of materials. More focus should also lie on improving occupant behavior and finding smart solar shading solutions for apartment buildings.

    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.

    Low-temperature district heating is a promising technology for providing homes with energy-efficient heating in the future. However, it is of great importance to maintain thermal comfort in existing buildings when district heating temperatures are lowered. This case study evaluated the actual radiator sizes and heating demands in 4 existing Danish single-family houses from the 1930s. A year-long dynamic simulation was performed for each of the houses to evaluate the potential to lower the heating system temperatures. The results indicate that there is a large potential to use low-temperature district heating in existing single-family houses. In order to obtain the full potential of low-temperature district heating, critical radiators must be replaced. Based on a novel method, a total of nine radiators were identified to be critical to ensure thermal comfort and low return temperatures in two of the case-houses. If these radiators were replaced it would be possible to lower the average heating system temperatures to 50 °C/27 °C in all four houses. - Highlights: • Comparison of dynamically calculated heat demands and radiator sizes. • Method for identification and evaluation of critical radiators was tested. • Existing houses can be heated with low-temperature heating for most of the year. • Replacing critical radiators helps ensure comfort and low return temperatures.

    2008-01-01

    Passive sampling of pollutants in water has been gaining acceptance for environmental monitoring. Previously, an integrative passive sampler (the Chemcatcher TM ) was developed and calibrated for the measurement of time weighted average concentrations of hydrophobic pollutants in water. Effects of physicochemical properties and environmental variables (water temperature and turbulence) on kinetic and thermodynamic parameters characterising the exchange of analytes between the sampler and water have been published. In this study, the effect of modification in sampler housing geometry on these calibration parameters was studied. The results obtained for polycyclic aromatic hydrocarbons show that reducing the depth of the cavity in the sampler body geometry increased the exchange kinetics by approximately twofold, whilst having no effect on the correlation between the uptake and offload kinetics of analytes. The use of performance reference compounds thus avoids the need for extensive re-calibration when the sampler body geometry is modified. - The effect of passive sampler geometry on accumulation kinetics of organic pollutants from water was evaluated

    In Denmark and in many countries around the world, housing markets are of considerable importance for households and policy-makers alike. As the boom and bust in the US and Danish housing market so aptly demonstrated, disruptions in the housing market potentially have wide-ranging consequences...... for individual households and for the aggregate economy. Housing is important because we all have to live somewhere, but also because it serves as a considerable source of both wealth and debt. As such, housing market policy can not only create vast benefits for many, but can also have substantial negative...... impacts for all, and should therefore be a topic of major interest for economists and policy makers alike.

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

    Directory of Open Access Journals (Sweden)

    Šubrt Roman

    2017-01-01

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

    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.

    Radon-222 levels were determined in 473 rooms of about 350 houses, 16 schools in Ramsar and its high-level natural radiation areas (HLNRAs) as well as in 89 rooms and many locations of old and new Ramsar Hotels. The AEOI (Atomic Energy Organization of Iran) Radon Diffusion Dosimeters applying electrochemical etching of polycarbonate detectors were used indoors during different seasons. The levels measured ranged from 20 to 3700 Bq.m -3 , detected in Talesh Mahalleh which has the highest natural radiation level in the area, corresponding to effective dose equivalents (H e ) up to 98.5 mSv.a -1 . The mean radon levels determined in different regions were 615 Bq.m -3 in Talesh Mahalleh, 326 Bq.m -3 in Chaparsar, 258 Bq.m -3 in schools of Ramsar and its HLNRAs, 246 Bq.m -3 in Ramak, 111 Bq.m -3 in Rasmar city, 50 Bq.m -3 in Sadat Mahalleh and Katalom, 49 Bq.m -3 Tonekabon and 27 Bq.m -3 in Talesh Mahalleh of Katalom; and 90 Be.m -3 in old and 50 Bq.m -3 in new Ramsar Hotels. It was found that houses built at a higher level above the ground even in the areas with the highest gamma exposures have lower radon levels compared to those built directly on the ground. The results of the radon levels determined in the above regions indoors are presented. (author). 10 refs, 9 figs, 3 tabs

    SINTEF has in cooperation with the projecting group for Maela School, worked towards smart and general concepts to achieve good comfort with low energy consumption, low environmental impact and low investments. The project is called 'Maela smart building'. Based on conceptual solutions chosen for Maela School, this might be one of the leading school buildings in concern of energy efficiency. To be sure of achieving the target of needed energy to be less than 80 kWh/m{sub 2}, this assumes that the solutions satisfies the demands elaborated with basis in the energy target for the building together with heating and ventilation technical outfit run optimally. If the real consumption shall decrease towards calculated energy needs, the users have to be conscious not to contribute in wasting energy. Further the management of heat and ventilation has to function optimally, the setpoint for heating and ventilation has to be precise. In addition the operators have to have insight in how a building like this functions and the right skills to run it correct. Emphasis on alternatives contributing positively to architecture and good indoor environment in addition to focus on energy efficiency were considered for technical designing of the conceptual heat and ventilation solutions. Generally the need for ventilation channels is reduced to a minimum and the mechanical ventilation is dimensioned considering air quality. Thermic comfort is secured by means of passive attempt such as natural ventilation, sun screening and exploitation of thermic substance in ceiling, walls and floor. Choice of windows and walls with translucent isolation implied some increased risk for overheated teaching wings in second floor in warm and sunny periods. Since these premises because of school vacation in summer, normally is not in use in the summer, the attempts such as sun screening, natural ventilation and night cooling (ventilation of surplus heat during nights),were considered sufficient

    The assessment of possible reduction of heating and cooling requirements of 300 m 2 house-office building has been presented in this paper, when simple Thermal Passive Techniques (TPT) have been applied to building's construction in Sebha city at the Libyan south. The known software for dynamic simulation (TRNSYS) has been used as an environment of digital experimentation for this study. A prototype represents the building has been constructed with the help of the available model of single thermal zone of TRNSYS (Type 19). The built-in ASHREA Transfer Function Method within this model has been used to calculate the heat flux through building's materials. Primarily, the thermal load on building's construction without TPTs has been evaluated under weather conditions of a Typical Meteorological Year (TMY) of Sebha city. Then, the building has been equipped with simple TPTs (such as the control of building materials, insulation, shading, infiltration and ventilation with windows resizing). This building was subjected to the same weather conditions and again the thermal load has been evaluated in order to report the percentage of reduction of thermal load. The simulation has been conducted successfully, where good assessment of reduction of annual heating and cooling demands in the building has been obtained. It is proved that, about (46%) of annual heating load and (48%) of annual cooling load can be reduced if suitable simple TPTs were incorporated in buildings.(Author)

    Carbon monoxide (CO) and particulate matter (PM 2.5) were measured in two reconstructed Danish farmhouses (17-19th century) during two weeks of summer. During the first week intensive measurements were performed while test cooking fires were burned, during the second week the houses were monitored while occupied by guest families. A masonry hearth was located in the middle of each house for open cooking fires and with heating stoves. One house had a chimney leading to the outside over the hearth; in the other, a brickwork hood led the smoke into an attic and through holes in the roof. During the first week the concentration of PM 2.5 averaged daily between 138 and 1650 μg m -3 inside the hearths and 21-160 μg m -3 in adjacent living rooms. CO averaged daily between 0.21 and 1.9 ppm in living areas, and up to 12 ppm in the hearths. Highest concentrations were measured when two fires were lit at the same time, which would cause high personal exposure for someone working in the kitchens. 15 min averages of up to 25 400 μg m -3 (PM 2.5) and 260 ppm CO were recorded. WHO air quality guidelines were occasionally exceeded for CO and constantly for PM 2.5. However, air exchange and air distribution measurements revealed a large draw in the chimney, which ensured a fast removal of wood smoke from the hearth area. The guest families were in average exposed to no more than 0.21 ppm CO during 48 h. Based on a hypothetical time-activity pattern, however, a woman living in this type of house during the 17-19th century would be exposed to daily averages of 1.1 ppm CO and 196 μg m -3 PM 2.5, which exceeds WHO guideline for PM 2.5, and is comparable to what is today observed for women in rural areas of developing countries.

[German] Das Umgebindehaus ist ein weltweit einmaliger Haustyp und zum anderen ist es ein traditionelles Haus unserer Region der Oberlausitz und angrenzender Teile von Boehmen und Schlesien. Das Symposium behandelt das Umgebindehaus in Vergangenheit und Gegenwart und will Motivation und Ansaetze geben, dieses wunderschoene Baukulturgut zu erhalten und unter modernen Wohn-, Arbeits- und Lebensbedingungen zu nutzen. Der zweite Teil der Tagung ist nicht minder wichtig. Beim Passivhaus geht es im wesentlichen darum, Heizwaermeverluste im Winter so klein zu halten, dass sie von den Gewinnen (Sonnenenergie, inneres Waermeaufkommen u.a.) gedeckt werden koennen. Damit wird der Waermeschutz des Gebaeudes vielleicht bis an die Grenzen getrieben und es entstehen neue Anforderungen an das Energiemanagement und die Qualitaet der technischen Gebaeudeausruestung.

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

  18. Technical - Economic Research for Passive Buildings

    Science.gov (United States)

    2017-10-01

    A newly constructed passive house must save 80 % of heat resources; otherwise it is not a passive house. The heating energy demand of a passive building is less than 15 kWh/m2 per year. However, a passive house is something more than just an energy-saving house. This concept involves sustainable, high-quality, valuable, healthy and durable construction. Features of a passive house: high insulation of envelope components, high-quality windows, good tightness of the building, regenerative ventilation system and elimination of thermal bridges. The Energy Performance of Buildings Directive (EPBD) 61 requires all new public buildings to become near-zero energy buildings by 2019 and will be extended to all new buildings by 2021. This concept involves sustainable, high-quality, valuable, healthy and durable construction. Foundation, walls and roofs are the most essential elements of a house. The type of foundation for a private house is selected considering many factors. The article examines technological and structural solutions for passive buildings foundation, walls and roofs. The technical-economic comparison of the main structures of a passive house revealed that it is cheaper to install an adequately designed concrete slab foundation than to build strip or pile foundation and the floor separately. Timber stud walls are the cheapest wall option for a passive house and 45-51% cheaper compared to other options. The comparison of roofs and ceilings showed that insulation of the ceiling is 25% more efficient than insulation of the roof. The comparison of the main envelope elements efficiency by multiple-criteria evaluation methods showed that it is economically feasible to install concrete slab on ground foundation, stud walls with sheet cladding and a pitched roof with insulated ceiling.

    In a normal wind year, Danish wind turbines generate the equivalent of approx. 20 percent of the Danish electricity demand. This paper argues that only approx. 1 percent of the wind power production is exported. The rest is used to meet domestic Danish electricity demands. The cost of wind power...... misleading. The cost of CO2 reduction by use of wind power in the period 2004-2008 was only 20 EUR/ton. Furthermore, the Danish wind turbines are not paid for by energy taxes. Danish wind turbines are given a subsidy via the electricity price which is paid by the electricity consumers.

  2. Does energy labelling on residential housing cause energy savings? Working paper

    Energy Technology Data Exchange (ETDEWEB)

    2008-12-15

    More than 80% of energy used in households is dedicated to space heating. Large potential energy savings have been identified in the existing housing stock. Energy labelling of single-family houses is seen as an important instrument to provide new house owners with information on efficient energy saving investments that can be made on the house. This paper evaluates the effects of the Danish Energy Labelling Scheme on energy consumption in existing single-family houses with propensity score matching using actual consumption of energy and register data describing the houses and households. We do not find significant energy savings due to the Danish Energy Labelling Scheme. (Author)

In import penetration tests, we find that its pricing and quantity decisions are independent of import price and quantity, implying that it can act to a considerable extent independently of its competitors. We also test whether it can act independently of its customers and find that its demand is inelastic with respect to its price. It thus holds a dominant posi...

    Poor uptake among socio-economically disadvantaged and susceptible populations is a well-known challenge of general health check interventions, and is widely cited as one of the reasons for the lack of population level effects seen in many studies. We report on patient characteristics among attendees and non-attendees of health checks made available to residents in the social housing sector of the municipality of Aarhus. We focus on this general population, as well as a particular sub-group living in an exceptionally deprived social housing area, and discuss the properties of intervention uptake that we need to be aware of to qualify and compare the effects of general versus targeted health checks in socially deprived areas. Cross-sectionally in a sample of 6650 residents of the Aarhus social housing sector who were invited for a health check in the first year of the 'Your Life - Your Health' program. The analyses consisted of 1) descriptive analysis of the characteristics of attenders/non-attenders, 2) unadjusted and adjusted Poisson regression to examine associations of patient characteristics and uptake of health checks, and 3) decision tree analyses (CHAID) to examine interaction and homogeneity in patient characteristics among attenders. Of the overall population 30% attended. In a nested cohort of people residing in a particularly deprived social housing settlement, 25% attended. Further, in the overall population, we found an association between the likelihood of taking up a health check and age, sex, country of origin, educational attainment, cohabitation, occupational status, and past medical treatment. In the nested cohort the association between uptake and medical treatment was non-significant, while the association between uptake and occupation was limited to people who were employed. These results resonate with past evidence on health check attendance. Attendance in the 'Your Life - Your Health' program is higher among people of a higher socio

    2001-01-01

    Since 1998 Denmark has been in a process of re-regulating its energy market introducing competition and incentive based economic regulation. The ''Danish model'' reflects specific Danish political priorities on energy, environment and the role of the energy consumers. The paper focuses on the electricity sector, tracing the reasons why Denmark re-regulates the way it does and what are the results. Denmark is a small country of 43000 2 kilometers and 5.3 million inhabitants. Denmark is a net-exporter of oil and gas produced in the North Sea. The hydro-resources are negligible. Renewable energy, however, covers 11 percent of gross energy consumption.(author)

  7. Protocol Monitoring Passive Solar Energy

    International Nuclear Information System (INIS)

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

    1998-01-01

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

    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.

  15. Dioxin in Danish air

    Energy Technology Data Exchange (ETDEWEB)

    Vikelsoe, J.; Andersen, H.V. [National Environmental Research Inst., Roskilde (Denmark)

    2004-09-15

    To gain more knowledge about dioxin levels, sources and emissions in Denmark, the Danish government year 2001 initiated the Danish Dioxin Monitoring Program. The program is a series of investigations, comprising soil, compost, percolate, bio-ash, incineration of municipal and hazardous waste, deposition, air, lake and fjord sediment as well as cows milk and human milk. The present paper describes the preliminary results for the continued investigation of air. Deposition of dioxin over land or sea is of major importance for the human exposure, which takes place mainly from food intake. The dioxin are emitted mainly to the atmosphere, therefore air measurements are well suited for tracking the transport and fate of dioxin from sources to exposure. Whereas measurements from chimneys has been frequently used to estimate the industrial emission from point sources such as incinerators, air measurements also include emission from diffuse sources such as larger urban or industrial regions, residential quarters, and from evaporation. Furthermore, emission measurements must be done on known sources, whereas air measurements include contribution from unknown source. The major drawbacks of air measurements are the long duration required (years), and the results depends on meteorological conditions, such as temperature, rainfall, wind speed and direction. The purpose of the present study has been to measure dioxins in Danish air, emphasizing - background concentrations and annual variation - difference between urban, rural and residential zones - influence from local sources and long range transport - connection between dioxin in air and deposition.

  16. The change in the primary production of Danish coastal waters

    Edelvang, K.; Erichsen, A.; Gustavson, K.; Bundgaard, K.; Dahl-Madsen, K.I.

    2001-01-01

    The background for this study is the development of the 'Farvandsmodel' for the NOVA-2003 programme and the nationally founded research project DECO (Danish Environmental Monitoring of Coastal Waters), which focuses on the use of remote sensing for the monitoring of Danish Coastal waters. Danish national programmes for the monitoring of the marine ecosystem are a relatively new activity, which has grown during the last 20 years. The HAV90 research programme amassed important information to be included in future environmental efforts such as the NOVA-2003 programme, aimed at monitoring the Danish coastal waters. The following is a selection of the topics mentioned in the NOVA-2003 programme (NOVA-2003, 2000) especially relevant to this study: 1) Hydrography. 2) Concentration and spatial distribution of nutrients. 3) Water and nutrient fluxes. 4) Oxygen depletion. As part of this programme, a 3D hydrographic model describing currents and fluxes in Danish waters has been designed by DHI Water and Environment for the Danish Ministry of Energy and Environment. The model is called the 'Farvandsmodel', which is the collective Danish name of this regional 3D hydrodynamic model and its associated database for storage and dissemination of model results and field measurements. The model is planned to be in operation until 2004. It has a great potential within hydrographic modelling in Danish waters, as it is capable of running 5-day prognoses for currents, water levels and stratification. The model is also able to calculate the sensitivity of the present system to changes in various input parameters. In this way the model may be used as a tool for testing the sensitivity of Danish coastal waters to the impact of the green house effects. The nationally funded research programme, DECO (1997-2000), aims to investigate the use of remote sensing for monitoring Danish coastal waters. To support this research, a eutrophication module (EU) was set up for the 'Farvandsmodel'. The

    The paper investigates ethnic minority concentration within social housing and the potentials of a strong social housing sector through an analysis of the housing careers of Somalis and Turks in Copenhagen. In a Danish context, the two ethnic groups differ greatly with respect to migration history......, socio-economic resources and family characteristics as well as distribution between tenures. It is therefore interesting to study whether these differences lead to differences in housing market choices and constraints. The majority of the interviewed Somalis and Turks made their housing careers within...... the social housing sector, which to the interviewees offered good housing options and possibilities for shaping their own housing careers. The majority of the Somalis perceived paying interest as being incompatible with Islam. Renting thus allowed them to adhere to their religious beliefs. The advantages...

    Andersen, C.E.; Damkjaer, A.; Ulbak, K.; Gravesen, P.

    2001-01-01

    A survey of radon in Danish dwellings has been carried out. The concentration of radon-222 has been measured in 3019 single-family houses and 101 multi-family houses (apartment complexes) with the so-called alpha-track technique (CR-39). On this basis, a map has been established. This map shows the percentage of single-family houses in each of the 275 municipalities with levels above 200 Bq/m 3 (i.e.) the action level recommended by the Danish building authorities for simple radon remedi-action). For Denmark as a whole, 4.6 % of the single-family houses are above 200 Bq/m 3 . That corresponds to 65 000 houses. In certain parts of the country (e.g. northern Jutland) less than 1 % are above 200 Bq/m 3 . In other places (e.g. certain parts of Funen and Bornholm) the value is above 10 %. In the survey, 15 houses had levels above 400 Bq/m 3 . The relationship between radon and various factors has been investigated with regression analysis. The three most important factors are type of basement, province, and soil type. The analysis confirms that the soil below the houses is the most important source of radon in Danish single-family houses. The study also provides a more detailed picture of the relation between geology and indoor radon. For example, it is shown that clayey till generates different indoor radon levels in the different parts of the country. The study does not indicate that a substantial part of newer Danish houses have an airtight house-soil interface. The report includes a summary in English. (au)

    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

    Recommendations for passive design and design tools based on European building codes were developed with extensive thermal simulations and a reference year especially prepared with hourly climate data from the central region of Chile. The results of the research were presented as a manual in Spanish enclosing simple design tools in an electronic spreadsheet. The design analysis is presented with a novel approach, that permits a better understanding and optimisation of the complex design balance between the demands for summer and winter in a mediterranean climate. The methodologies and approach that were developed are extended to other climatic regions. This way the investigation supports the improvement of thermal comfort conditions and the application of solar energy in dwellings as essential elements of a process of sustainable development.

    In 2012, the U.S. Department of Energy (DOE) recognized the value of performance-based passive building standards when it joined with Passive House Institute US (PHIUS) to promote DOE’s Challenge Home program in tandem with the PHIUS+ Certification program. Since then, the number of passive building projects that have been certified under the partnership has grown exponentially because of some synergy. Passive building represents a well-developed approach to arrive at the envelope basis for zero energy and energy-positive projects by employing performance-based criteria and maximizing cost-effective savings from conservation before implementing renewable energy technologies. The Challenge Home program evolved into the Zero Energy Ready Home (ZERH) program in a move toward 1) attaining zero energy and 2) including active renewable energy generation such as photovoltaics (PV)—toward the zero energy goal.

  11. Does energy labelling on residential housing cause energy savings?

    Energy Technology Data Exchange (ETDEWEB)

    2009-07-01

    Danish households use more than 30% of the total amount of energy being used in Denmark. More than 80% of this energy is dedicated to space heating. The same relation is seen in many OECD countries. The corresponding energy savings potential was recently estimated at 30% of the energy used in buildings. Energy labelling is seen as an important instrument to target these potential energy savings. This paper evaluates the effects of the Danish Energy Labelling Scheme on energy consumption in existing single-family houses with propensity score matching using real metered natural gas consumption and a very wide range of register data describing the houses and households. The study did not find significant energy savings due to the Danish Energy Labelling Scheme, but more research would be needed to complement this conclusion

    insulation in a Danish single-family detached home. This single family house, is based on averages of current Danish construction practices with building heat losses estimated using Be10. To simulate a changing district heating grid mix, heat supply fuel sources are modeled according to Danish energy mix...... for space heating without insulation over the lifespan of a building. When the energy sources for insulation production are similar to the energy mix that supplies heat, this logic is valid to very high level of insulation. However, in Denmark, as well as many other countries this assumption is becoming...... increasingly incorrect. Given the generally long service life of buildings, the significance of future energy mixes, which are expected/intended to have a smaller environmental impact, can be great. In this paper, a reference house is used to assess the life cycle environmental impacts of mineral wool...

    Purpose: Dyslexia is a long lasting problem in learning to decode written words accurately and fluently. This definition suggests that dyslexia remains sufficiently constant to be assessed reliably with just one wide-range test across all educational levels. The current study investigated...... this possibility by asking whether students who receive special support in reading differ from other students on the same scale of decoding across all educational levels. Method: Decoding and spelling measures from a newly developed, web-based Danish dyslexia test were taken from 1564 students from Grade 3...... 9. Measures of decoding difficulties were reliably associated with current practices for referral to special support at all educational levels. On average, students receiving special support performed at the 5th percentile of the unselected groups. The results suggest that a wide-range test...

    Political parties have as their main assignment the creation of linkage between citizens and government. They provide one of several channels of participation in modern democracies. Yet, the general trend across the Western world is that party membership figures decline. The purpose of this article...... is to report on the state of Danish party membership; the numbers and participation. The claim of the article is that total membership figures hide evidence of membership renewal and increases, and that mere party membership figures are insufficient when evaluating political parties as channels...... of participation. Instead, membership figures at party level as well as the participation of party members need to be taken into account in order to assess parties as channels of participation. This is supported by the analyses reported here which show that even though membership figures are declining, parties...

    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.

    Columbia County (New York) Habitat for Humanity built a pair of townhomes to Passive House criteria with the purpose of exploring approaches for achieving Passive House performance and to eventually develop a prototype design for future projects. The project utilized a 2x6 frame wall with a structural insulated panel curtain wall and a ventilated attic over a sealed OSB ceiling air barrier. Mechanical systems include a single head, wall mounted ductless mini-split heat pump in each unit and a heat recovery ventilator. Costs were $26,000 per unit higher for Passive House construction compared with the same home built to ENERGY STAR version 3 specifications, representing about 18% of total construction cost. This report discusses the cost components, energy modeling results and lessons from construction. Two alternative ventilation systems are analyzed: a central system; and, a point-source system with small through-wall units distributed throughout the house. The report includes a design and cost analysis of these two approaches.

  19. Inequality and poverty in the Danish Welfare State

    DEFF Research Database (Denmark)

    Christensen, Anders Bøggild

    2010-01-01

    Denmark has experienced high levels of employment since the mid-1990s, and the unemployment rate in 2008 was the lowest since the 1970s. Paradoxically, the levels of relative poverty and inequality increased during the same period. This paradox only applies to poverty studies based on median...... disposal income, but this approach is the most widespread in Danish research. However, there is general agreement concerning the increasing inequality and that groups such as young people, ethnic minorities and those relying on social assistance are increasingly at risk. Contrary to theories...... of globalisation and demographical changes in the Danish case, the rising inequality appears to be especially driven by the housing and stock markets. The so-called ‘financial crisis’ has affected both of these markets deeply, which could have an impact on any further developments in inequality. Conversely...

The study of satiation processes offers an interesting approach to the relationship between housing and mental health. Man requires new stimuli to motivate him. Boredom and satiation serve to induce passivity and may provoke destructive behaviour and escapism. Finland has the highest percentage of dwellings constructed in the immediate post-war period of any country in Europe, and in respect of the functions of housing many aspects are still apparent which are detrimental to mental health.

    The need for energy retrofitting of the Danish single-family houses is massive, especially for the high proportion of single-family houses built in the 1960s and 1970s. But even though the potential benefits are many, only few families embark on a major energy retrofit. There may be many reasons...... for this. An obvious one may be limited knowledge of non-energy benefits, e.g. in relation to the indoor climate. The objective of this study was to explain this limited effort to save energy by identifying barriers and incentives among house owners in relation to energy retrofitting of one’s own house....... Moreover, it was investigated among house owners, who had carried out energy retrofitting, whether a number of factors, including the perceived indoor climate, became better or worse after retrofitting. A questionnaire survey was carried out among 1,990 house owners in a municipality north of Copenhagen...

    1998-12-31

    In Denmark biogas is produced from several different types of facilities: Anaerobic industrial waste and waste water treatment plants, anaerobic sludge stabilization plants, landfill gas plants and single farm and centralized biogas plants. Centralized biogas plants account for approximately 40% of the total production of biogas. In the recent 5 years the single farm plant technology has been considerably improved. Standardized concepts has been developed, which have decreased the construction price of single farm plants, and the introduction of dual fuel gas engines has lowered the cost and increased the efficiency of the energy production unit. Dual fuel gas engines use 7-10% diesel oil together with the gas. They are based on diesel engine principles, often they are modified standard diesel engines, which are cheaper and more simple than ignition gas engines. The construction cost for a typical single farm plant with a 150-200 m{sup 3} reactor is 200,000 USD. As the farmer can obtain a 30% funding from the Danish Energy Agency, the net cost for the farmer is 134,000 USD. The annual income if manure and some industrial waste in co-digested is around 30,000-35,000 USD and the annual running costs is in the level of 5,000-6,000 USD. (EG)

  16. 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.

    2001-07-01

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

  11. NucleDyne's passive containment system

    International Nuclear Information System (INIS)

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

    1987-01-01

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

We wanted to assess whether this is also true for Danish cattle. Data from 578 Danish Holstein herds were analysed with a mixed effect model...... and contrary to the findings in the US, we found that cows produced higher volumes of milk if they had a bull calf compared to a heifer calf. We found a significantly higher milk production of 0.28% in the first lactation period for cows giving birth to a bull calf, compared to a heifer calf. This difference...... was even higher when cows gave birth to another bull calf, so having two bull calves resulted in a difference of 0.52% in milk production compared to any other combination of sex of the offspring. Furthermore, we found that farmer assisted calvings were associated with a higher milk yield. Cows...

  9. Fake passports and appointed communities: Nation and transnationalism in the Danish asylum system

    DEFF Research Database (Denmark)

    Whyte, Zachary

    2003-01-01

    Nationality underwrites a great deal of the Danish asylum process, and of the refugee regime as a whole. The housing and care of asylum seekers, handled by the Danish Red Cross, is based on classifications by nationality. Bending a phrase from Benedict Anderson, these might be called "appointed...... communities". While the Danish asylum system in principle performs individual determination procedures for asylum seekers, granting refugee status on a case-by-case basis, in practice those identified as Iraqi or Afghani have had a very high acceptance rate. However, it is clearly the case that not all asylum...... seekers have citizenship of the countries they claim to come from, or indeed feel they come from the countries of which they have citizenship. In this context, we must enquire about the mechanics of determining nationality and about how asylum seekers themselves relate to national identities. I argue...

  11. Passive athermalization of doublets in 8-13 micron waveband

    Science.gov (United States)

    Schuster, Norbert

    2014-10-01

    Passive athermalization of lenses has become a key-technology for automotive and other outdoor applications using modern uncooled 25, 17 and 12 micron pixel pitch bolometer arrays. Typical pixel counts for thermal imaging are 384x288 (qVGA), 640x480 (VGA), and 1024x768 (XGA). Two lens arrangements (called Doublets) represent a cost effective way to satisfy resolution requirements of these detectors with F-numbers 1.4 or faster. Thermal drift of index of refraction and the geometrical changes (in lenses and housing) versus temperature defocus the initial image plane from the detector plane. The passive athermalization restricts this drop of spatial resolution in a wide temperature range (typically -40°C…+80°C) to an acceptable value without any additional external refocus. In particular, lenses with long focal lengths and high apertures claim athermalization. A careful choice of lens and housing materials and a sophistical dimensioning lead to three different principles of passivation: The Passive Mechanical Athermalization (PMA) shifts the complete lens cell, the Passive Optical and Mechanical Athermalization (POMA) shifts only one lens inside the housing, the Passive Optical Athermalization (POA) works without any mechanism. All three principles will be demonstrated for a typical narrow-field lens (HFOV about 12°) with high aperture (aperture based F-number 1.3) for the actual uncooled reference detector (17micron VGA). Six design examples using different combinations of lens materials show the impact on spatial lens resolution, on overall length, and on weight. First order relations are discussed. They give some hints for optimization solutions. Pros and cons of different passive athermalization principles are evaluated in regards of housing design, availability of materials and costing. Examples with a convergent GASIR®1-lens in front distinguish by best resolution, short overall length, and lowest weight.

    A journal bearing provides vertical and radial stability to a rotor of a passive magnetic bearing system when the rotor is not rotating and when it is rotating. In the passive magnetic bearing system, the rotor has a vertical axis of rotation. Without the journal bearing, the rotor is vertically and radially unstable when stationary, and is vertically stable and radially unstable when rotating.

  13. Calculated shielding factors for selected European houses

    1984-12-01

    Shielding factors for gamma radiation from activity deposited on structures and ground surfaces have been calculated with the computer model DEPSHIELD for single-family and multi-storey buildings in France, United Kingdom and Denmark. For all three countries it was found that the shielding factors for single-family houses are approximately a factor of 2 - 10 higher that those for buildings with five or more storeys. Away from doors and windows the shielding factors for French, British, and Danish single-family houses are in the range 0.03 - 0.1, 0.06 - 0.4, and 0.07 - 0.3, respectively. The uncertainties of the calculations are discussed and DEPSHIELD-results are compared with other methods as well as with experimental results. (author)

    Many of the basic elements of passive solar design are reviewed. The unique design constraints presented in passive homes are introduced and many of the salient issues influencing design decisions are described briefly. Passive solar construction is described for each passive system type: direct gain, thermal storage wall, attached sunspace, thermal storage roof, and convective loop. For each system type, important design and construction issues are discussed and case studies illustrating designed and built examples of the system type are presented. Construction details are given and construction and thermal performance information is given for the materials used in collector components, storage components, and control components. Included are glazing materials, framing systems, caulking and sealants, concrete masonry, concrete, brick, shading, reflectors, and insulators. The Load Collector Ratio method for estimating passive system performance is appended, and other analysis methods are briefly summarized. (LEW)

    This paper investigates an energy conservation and dissipation -- passivity -- aspect of dynamic models in evolutionary game theory. We define a notion of passivity using the state-space representation of the models, and we devise systematic methods to examine passivity and to identify properties of passive dynamic models. Based on the methods, we describe how passivity is connected to stability in population games and illustrate stability of passive dynamic models using numerical simulations.

    The nationwide Danish Testicular Cancer database consists of a retrospective research database (DaTeCa database) and a prospective clinical database (Danish Multidisciplinary Cancer Group [DMCG] DaTeCa database). The aim is to improve the quality of care for patients with testicular cancer (TC) in Denmark, that is, by identifying risk factors for relapse, toxicity related to treatment, and focusing on late effects. All Danish male patients with a histologically verified germ cell cancer diagnosis in the Danish Pathology Registry are included in the DaTeCa databases. Data collection has been performed from 1984 to 2007 and from 2013 onward, respectively. The retrospective DaTeCa database contains detailed information with more than 300 variables related to histology, stage, treatment, relapses, pathology, tumor markers, kidney function, lung function, etc. A questionnaire related to late effects has been conducted, which includes questions regarding social relationships, life situation, general health status, family background, diseases, symptoms, use of medication, marital status, psychosocial issues, fertility, and sexuality. TC survivors alive on October 2014 were invited to fill in this questionnaire including 160 validated questions. Collection of questionnaires is still ongoing. A biobank including blood/sputum samples for future genetic analyses has been established. Both samples related to DaTeCa and DMCG DaTeCa database are included. The prospective DMCG DaTeCa database includes variables regarding histology, stage, prognostic group, and treatment. The DMCG DaTeCa database has existed since 2013 and is a young clinical database. It is necessary to extend the data collection in the prospective database in order to answer quality-related questions. Data from the retrospective database will be added to the prospective data. This will result in a large and very comprehensive database for future studies on TC patients.

    2000-07-01

    The Association of Danish Electric Utilities issues each year the statistical yearbook 'Danish electricity supply'. By means of brief text, figures, and tables a description is given of the electric supply sector. The total electric power consumption in 1999 is almost the same as in 1998. There has been a moderate consumption increase in the households and the service sector whereas the consumption in industry has decreased. 1999 is the first year with actual competition in the power-producing sector. The increased competition from the Scandinavian hydro-electric power plants and the growing number of privately owned wind turbines and other decentralised power plants result in a decline in the power production at the electric utilities of 10% compared to the year 1998. In 1999 electric power from renewable energy sources such as wind, biomass, and waste covers close to 10% of the total Danish power consumption. More than 400 new turbines are installed in 1999 and the total capacity of wind power increases with ca. 20%. The actual energy content of the wind in 1999 was, however, 15% lower than normally which results in a significant reduction of the utilisation of the wind turbine capacity. (ln)

Patients ≥18 years operated for groin hernia. Type and size of hernia, primary or recurrent, type of surgical repair procedure, mesh and mesh fixation methods. According to the Danish National Health Act, surgeons are obliged to register all hernia repairs immediately after surgery (3 minute registration time). All institutions have continuous access to their own data stratified on individual surgeons. Registrations are based on a closed, protected Internet system requiring personal codes also identifying the operating institution. A national steering committee consisting of 13 voluntary and dedicated surgeons, 11 of whom are unpaid, handles the medical management of the database. The Danish Inguinal Hernia Database comprises intraoperative data from >130,000 repairs (May 2015). A total of 49 peer-reviewed national and international publications have been published from the database (June 2015). The Danish Inguinal Hernia Database is fully active monitoring surgical quality and contributes to the national and international surgical society to improve outcome after groin hernia repair.

  19. Windows in Low Energy Houses. Size Matters

    Energy Technology Data Exchange (ETDEWEB)

    Persson, Mari-Louise

    2004-06-01

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

    Passive states are defined as those states that do not allow for work extraction in a cyclic (unitary) process. Within the set of passive states, thermal states are the most stable ones: they maximize the entropy for a given energy, and similarly they minimize the energy for a given entropy. Here we find the passive states lying in the other extreme, i.e., those that maximize the energy for a given entropy, which we show also minimize the entropy when the energy is fixed. These extremal properties make these states useful to obtain fundamental bounds for the thermodynamics of finite-dimensional quantum systems, which we show in several scenarios.

    A Danish architect and planning firm, ''Praxis'' (Aarhus), and the Scottish firm ''Heatwise'' (Glasgow), backed up by the Ministry of Housing, the Scottish Development Agency and the European Communities, have cooperated in order to examine the Scottish market for Danish ''know-how'' concerning energy conservation and efficiency in relation to the heating of residential buildings. Danish experts could also advise on energy policy and planning and renewable energy sources. The buildings on a large peripheral housing estate were examined in detail, especially with regard to heat losses caused by insufficient insulation and inefficient heating systems. it was discovered that the cost of raising the standard of heating in Scottish residences to that of the average Danish ones would be approximately 7 milliard pounds including necessary general repairs and upheep. There are also many barriers to development inspired by Danish know-how and technology - some being the lack of economical resources and as Glasgow is a town with great poverty problems, other needs hold higher priority amongst its inhabitants. However cooperation between the Danish and English firms will continue. (AB).

    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.

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

    1992-01-01

    A method and apparatus are provided for passively cooling the control rod drive mechanisms (CRDMs) in the reactor vessel of a nuclear power plant. Passive cooling is achieved by dispersing a plurality of chimneys within the CRDM array in positions where a control rod is not required. The chimneys induce convective air currents which cause ambient air from within the containment to flow over the CRDM coils. The air heated by the coils is guided into inlets in the chimneys by baffles. The chimney is insulated and extends through the seismic support platform and missile shield disposed above the closure head. A collar of adjustable height mates with plate elements formed at the distal end of the CRDM pressure housings by an interlocking arrangement so that the seismic support platform provides lateral restraint for the chimneys.

    In one embodiment, active (continuous or intermittent) passivation may be employed to prevent interaction of sticky molecules with interfaces inside of an instrument (e.g., an infrared absorption spectrometer) and thereby improve response time. A passivation species may be continuously or intermittently applied to an inlet of the instrument while a sample gas stream is being applied. The passivation species may have a highly polar functional group that strongly binds to either water or polar groups of the interfaces, and once bound presents a non-polar group to the gas phase in order to prevent further binding of polar molecules. The instrument may be actively used to detect the sticky molecules while the passivation species is being applied.

  12. Passive radon daughter dosimeters

    McElroy, R.G.C.; Johnson, J.R.

    1986-03-01

    On the basis of an extensive review of the recent literature concerning passive radon daughter dosimeters, we have reached the following conclusions: 1) Passive dosimeters for measuring radon are available and reliable. 2) There does not presently exist an acceptable passive dosimeter for radon daughters. There is little if any hope for the development of such a device in the foreseeable future. 3) We are pessimistic about the potential of 'semi-passive dosimeters' but are less firm about stating categorically that these devices cannot be developed into a useful radon daughter dosimeter. This report documents and justifies these conclusions. It does not address the question of the worker's acceptance of these devices because at the present time, no device is sufficiently advanced for this question to be meaningful. 118 refs

    Full Text Available Droplet-based micromixers are essential units in many microfluidic devices for widespread applications, such as diagnostics and synthesis. The mixers can be either passive or active. When compared to active methods, the passive mixer is widely used because it does not require extra energy input apart from the pump drive. In recent years, several passive droplet-based mixers were developed, where mixing was characterized by both experiments and simulation. A unified physical understanding of both experimental processes and simulation models is beneficial for effectively developing new and efficient mixing techniques. This review covers the state-of-the-art passive droplet-based micromixers in microfluidics, which mainly focuses on three aspects: (1 Mixing parameters and analysis method; (2 Typical mixing element designs and the mixing characters in experiments; and, (3 Comprehensive introduction of numerical models used in microfluidic flow and diffusion.

    2005-01-01

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

  16. CANDU passive shutdown systems

    Energy Technology Data Exchange (ETDEWEB)

    Hart, R S; Olmstead, R A [AECL CANDU, Sheridan Park Research Community, Mississauga, ON (Canada)

    1996-12-01

    CANDU incorporates two diverse, passive shutdown systems, independent of each other and from the reactor regulating system. Both shutdown systems function in the low pressure, low temperature, moderator which surrounds the fuel channels. The shutdown systems are functionally different, physically separate, and passive since the driving force for SDS1 is gravity and the driving force for SDS2 is stored energy. The physics of the reactor core itself ensures a degree of passive safety in that the relatively long prompt neutron generation time inherent in the design of CANDU reactors tend to retard power excursions and reduces the speed required for shutdown action, even for large postulated reactivity increases. All passive systems include a number of active components or initiators. Hence, an important aspect of passive systems is the inclusion of fail safe (activated by active component failure) operation. The mechanisms that achieve the fail safe action should be passive. Consequently the passive performance of the CANDU shutdown systems extends beyond their basic modes of operation to include fail safe operation based on natural phenomenon or stored energy. For example, loss of power to the SDS1 clutches results in the drop of the shutdown rods by gravity, loss of power or instrument air to the injection valves of SDS2 results in valve opening via spring action, and rigorous self checking of logic, data and timing by the shutdown systems computers assures a fail safe reactor trip through the collapse of a fluctuating magnetic field or the discharge of a capacitor. Event statistics from operating CANDU stations indicate a significant decrease in protection system faults that could lead to loss of production and elimination of protection system faults that could lead to loss of protection. This paper provides a comprehensive description of the passive shutdown systems employed by CANDU. (author). 4 figs, 3 tabs.

    This paper explores how changes in regulatory requirements for energy efficiency in buildings (in the US also known as building energy codes) affect household energy consumption. The focus in this paper is on natural gas consumption by Danish single-family owner-occupied houses. Unlike most other...... advanced econometric methods we examine differences in heating energy consumption due to different building regulation requirements at the time of house construction. As for the effect of the building regulation, we find that changes in Danish building regulations have led to significant reductions...... in energy used for heating. The latest revision of the Danish building regulation covered by this paper is that of 1998. This revision has resulted in a 7% reduction in natural gas consumption....

    The aim of the database, which has existed for registration of all patients with colorectal cancer in Denmark since 2001, is to improve the prognosis for this patient group. All Danish patients with newly diagnosed colorectal cancer who are either diagnosed or treated in a surgical department of a public Danish hospital. The database comprises an array of surgical, radiological, oncological, and pathological variables. The surgeons record data such as diagnostics performed, including type and results of radiological examinations, lifestyle factors, comorbidity and performance, treatment including the surgical procedure, urgency of surgery, and intra- and postoperative complications within 30 days after surgery. The pathologists record data such as tumor type, number of lymph nodes and metastatic lymph nodes, surgical margin status, and other pathological risk factors. The database has had >95% completeness in including patients with colorectal adenocarcinoma with >54,000 patients registered so far with approximately one-third rectal cancers and two-third colon cancers and an overrepresentation of men among rectal cancer patients. The stage distribution has been more or less constant until 2014 with a tendency toward a lower rate of stage IV and higher rate of stage I after introduction of the national screening program in 2014. The 30-day mortality rate after elective surgery has been reduced from >7% in 2001-2003 to database is a national population-based clinical database with high patient and data completeness for the perioperative period. The resolution of data is high for description of the patient at the time of diagnosis, including comorbidities, and for characterizing diagnosis, surgical interventions, and short-term outcomes. The database does not have high-resolution oncological data and does not register recurrences after primary surgery. The Danish Colorectal Cancer Group provides high-quality data and has been documenting an increase in short- and long

  14. Development of Danish wind power market

    Meyer, Niels I.

    2004-01-01

    The modern phase of Danish wind power started after the oil crisis in 1973. Based on long traditions of Danish wind power dating back to the beginning of the century a new commercial phase was initiated by small industrial entrepreneurs with support by the Danish government, the Danish Academy of Technical Sciences and green organizations. During the eighties technological development resulted in increased cost efficiency, while the investment subsidies from the state were gradually phased out. Conflicts between utilities and wind power producers over tariffs and the costs of grid connections, then slowed down the penetration of wind power on the Danish market. In addition, many local municipalities were setting up administrative barriers for wind turbines. These barriers were removed by government intervention in the early nineties when favourable feed-in tariffs were introduced together with easy access to the grid, simple procedures for construction allowances and priority to green electricity. As a result wind power was booming in the Danish home market and Danish turbines achieved a global market share of around 50%. After a change of government in December 2001, however the Danish home market for wind power has more or less collapsed. (Author)
