The relevance of passive energy saving technologies in energy efficient low-rise construction in Russia is indicated. The definition of a passive house and its feature is given. Indicated that an attractive source of energy for heating the house is the energy of the sun. The definition of a solar house is given. The requirements for a solar passive house during its design are described: compact form of the house, optimal orientation of the house to the cardinal points, differentiation of glazing at home, passive use of solar energy, etc. It is noted that the most common system of passive heating of a house is to heat insulated glazed volume between nature and internal space of the house (vegetarian). The definition of a vegetarian is given, its design, features and advantages are described. Considered and analyzed various ways of heating solar houses from a vegetarian: a semi-direct, indirect, thermosiphon system with heating and circulation of warm air around the house. The classification of solar houses is discussed depending on the architectural solution for the placement of the vegetarian: a detached house with a vegetarian; a house with a vegetarian adjoining its main living space; a house located with a vegetarian under a common roof; a house with a vegetarian built into its living volume, a house with a “double shell”. The following types of vegetarians are listed: attached to an existing house, built into the house or being a “second shell” for the house. Practical recommendations for optimal work of a vegetarian are given: the need for special glazing (thermal mirror), protection from sunlight in the summer. The conclusion is made about the prospects of solar houses with a vegetarian due to the clear advantages of the passive heating system of the house and a high architectural and aesthetic level.

With the rapid urban development of Lhasa in Tibet Autonomous Region, the traditional houses are losing gradually, while a great variety of city housing are springing up all over the city. Spatial patterns of city housing don’t blindly imitate commercial housing in most other cities in china, but have unique characteristics, such as building direction, functional layout, hole set, building construction and so on. The paper selects four types of Lhasa housing, rural traditional dwelling house, low-income apartment, detached house and multi-storey house, to analysis application of passive technology in detail and sums up three developing stages of passive technology in Lhasa area. On the basis, the paper discusses major factors about evolution of passive technology, that they are changes of spatial patterns, structure system and way of energy consumption. In the end, the paper puts forward some suggestions on the passive technology application in new city housing.

Within the European framework, the passive house has become an essential constructive solution in terms of building efficiency and CO2 reduction. However, the main approaches have been focused on post-occupancy surveys, measurements of actual energy consumption, life-cycle analyses in dynamic conditions, using simulation, and the estimation of the thermal comfort. Few studies have assessed the in situ performance of the building fabric of passive houses. Hence, this paper explores the applicability of non-destructive techniques—heat flux meter (HFM) and quantitative infrared thermography (QIRT)—for assessing the gap between the predicted and actual thermal transmittance of passive house façades under steady-state conditions in the Mediterranean climate. Firstly, the suitability of in situ non-destructive techniques was checked in an experimental mock-up, and, subsequently, a detached house was tested in the real built environment. The findings revealed that both Non-Destructive Testing (NDT) techniques allow for the quantification of the gap between the design and the actual façades U-value of a new passive house before its operational stage. QIRT was faster than the HFM technique, although the latter was more accurate. The results will help practitioners to choose the most appropriate method based on environmental conditions, execution of the method, and data analysis.

Due to the changes in the energy standards for housing in Poland there are many concerns. Is the standard required by the regulation achievable and if it is, then at what cost? There are many solutions to construct a building in line with the requirements of passive house technology. They are differentiated by price and time required for implementation. This study is based on the solution proposed by one of Polish companies, offering technologically integrated products allowing, according to the producer, to build passive houses faster and easier. The goal of this study was to confront producer’s claim with reality by comparing time and cost of the same investment using conventional and passive house technology. The basis for time and cost analysis was a basic detached house design, partially modified with regards to materials and technology used. Conclusions of the study are based on the comparison of the two Gantt charts defined in Ms Project. Construction schedule was used to analyse the duration of both projects and the resources assignment was used in cost analysis.

In order to retain good indoor air quality through the year in detached houses with passive ventilation systems, the authors investigated a mechanical control air-supply method. Firstly, indoor environments in houses with passive ventilation systems with thermal dampers, were examined using a simulation program (Fresh). Secondly, a passive ventilation system with a thermal damper, an under-floorheating system with a heat pump and were installed in an airtight house at Maebashi in Japan and measurements on its ventilation characteristics and indoor air quality were made. The simulation results showed that if the thermal damper is well tuned, this mechanically controlled air-supply opening keeps ventilation rates adequate through the year especially in airtight houses. The measurement results showed that the ventilation rates were kept above the required level through the year and the TVOC concentration decreases from 3000 to 200 μg/m3 in 5 months after the construction.

Full textAbstract:
This study investigated the effect of passive strategies (orientation, thermal mass of building structure, window opening, and window properties) and the usage of an active cooling system on energy demand and indoor temperature conditions of a detached house in Finland in the current (TRY 2012) and future climatic conditions (2050). So that nine different cases were defined and simulated. The goal was to improve the indoor temperature conditions in the cooling season and analyze the effects of global warming on energy demand. Regarding the results of passive strategies, in the current climate, using openable windows would be the best solution for decreasing the cooling demand and providing acceptable indoor air temperature of the spaces. In this case, 96% of the time in the cooling season, the indoor temperature is below the maximum recommended indoor temperature (27 °C) of the thermal environment category III of the standard EN 15251 and EN 16798–1. While using an active cooling system in the hall of the upper floor, it is the only studied solution that can provide thermal comfort in all the spaces during the cooling season in both current and future climate based on the standards. In the future 2050 climate, the heating demand decreases much more than the amount of increase in the cooling demand. So that the total electricity demand of electrically heated detached houses in the future climate would be less than in the current climate.

INTRODUCTION Recent development has seen a drastic increase in energy use trends in Saudi Arabian buildings leading to a demand for an effective course of action for energy conservation and production. A case study-based research initiative exploring near-zero energy potential in Saudi Arabia was undertaken. A 4-bedroom detached single-family faculty residence at King Fahd University of Petroleum and Minerals (KFUPM) representing common regional housing design trends was utilized. A base case simulation model of the house was developed and validated using short-term and real-time energy consumption data. Three sets of strategies: passive design strategies, representative codes and standards, and renewable technology were employed in the new design of the house. Passive strategies comprised a green roof, a ventilated wall system, a sloped roof, and insulation for thermal bridges. These alternatives helped reduce the annual energy consumption of the house by 17.2%. The most recent version of the International Energy Conservation Code (IECC 2012) was also incorporated along with ASHRAE Standard 62.2 for ventilation. The code and standard together reduced the annual energy consumption by 31.1%. Solar PV was then utilized to reduce grid utilization for the remainder of the house energy loads. This strategy provided 24.7% of the total energy consumed annually. A combination of strategies showed a 70.7% energy consumption reduction, thereby decreasing the energy index of the house from 162.9 to 47.7 kWh/m2/yr. The Zero Energy Building (ZEB) concepts and strategies utilized in this study demonstrate a socially responsible approach to achieving near-zero energy performance for an existing house.

Japan signed the Kyoto Protocol to reduce the nation's carbon dioxide (CO2) emission by 6% below the 1990 level. The housing industry is no exception being required to reduce the negative impact of the housing delivery on the environment. Today, all newly-constructed detached houses being built by Sekisui House Ltd. are designed to alleviate the societal pressure, accompanied basically with the following techniques and/or technologies: (1) the reduction of energy use relating to air-conditioning by improving the houses' insulation performance to meet Japan's energy saving standard set in 1999, as well as ventilation by making use of a passive ventilation system driven by stack effect; (2) the reduction of energy consumption that derives from domestic hot water by applying a high-efficient water heater, where the system performance is improved from 80% to 95% of the efficiency-today, Japanese housing manufacturers also tend to promote the installation of a gas engine cogeneration system and air-source heat pump water heater in housing; (3) the micro-power generation by the installation of solar photovoltaic (PV) power generation system; and (4) the cooling effect achieved by tree shading, which helps lower the ambient temperature around buildings during the summer. The company's ‘Action Plan 20’ reflects the global warming prevention (or CO2 emission reduction) strategy, considered to be effective in the delivery of low-carbon housing in Japan.

Full textAbstract:
Reynolds number has significant impact on the aerodynamic performance of axial turbines. The internal flow within the stator of a low pressure turbine could be all laminar when the inlet Reynolds number is very low, and large flow separation may occur on the suction surface of the blade. The separated laminar boundary layer and the wake have strong unsteady interactions with the main flow in rotor passages. In order to investigate the laminar flow separation and the interaction, both laminar flow simulation and detached eddy simulation (DES) have been performed on a low speed axial turbine under a very low Reynolds number condition in this paper. For comparison, fully laminar modeling, transitional modeling and fully turbulent modeling are performed, also. The comparison between the computational results and the experimental results shows that both the laminar modeling and transition modeling can capture the laminar separation on the suction side of the stator blade accurately. The separation region locates in a thin zone strengthening from the blade tip to the hub, which is induced by the tip passage vortex. The separation generates a high turbulence intensity zone at the stator outlet. However, this zone in laminar simulation is smaller than that in the experimental due to the absence of turbulence disturbances. Fully turbulent modeling predicts a delayed separation and a smaller separation region. Detached eddy simulation is performed for single stator row, which gives better predictions for both the flow separation and high turbulent zone. The detailed flow structures of the secondary vortices of the stator, the rotor passage vortex and the tip leakage vortex are illustrated. The simulation results show that the laminar separation has obvious three dimensional behaviour. The radial movement of the horse shoe vortex is the main disturbance to the flow separation.

Un remanso desde el que contemplar la naturaleza en un paisaje que tiene como telón de fondo al Mar Mediterráneo… se concibe la totalidad del territorio como materia de proyecto. Respetar al máximo el lugar, la naturaleza y potenciar al máximo la contemplación y disfrute de este entorno natural son los factores que determinan los puntos de partida en el diseño de esta vivienda. La idea de este proyecto nace de la propia morfología del lugar, proyectando desde y para el entorno. Bajo esta premisa se lleva a cabo la construcción de este edificio, supeditando el uso y la ubicación de la vivienda a la geometría de la parcela y adaptándose tanto a la orientación como a las vistas del solar. Proponemos una arquitectura de territorio, que la presencia de nuestra construcción impulse a imaginarse el lugar donde se erige. Un edificio que parezca estar fuertemente enraizado en el suelo, que de la impresión de ser una parte natural de su entorno. Como dice Peter Zumthor en su libro Pensar la Arquitectura: “Despierta toda mi pasión poder proyectar edificios que, con el correr del tiempo, queden soldados de esta manera natural con la forma y la historia del lugar donde se ubican.***A haven in which one can contemplate nature in a landscape with the Mediterranean Sea as backdrop... the entire territory is conceived as an additional material in the project. The respect to the settings and the surrounding nature, as well as maximizing both contemplation and enjoyment of this natural environment, are the key factors that determine the starting points in the design of this dwelling. The idea of this project arises from the own morphology of the site, designing from and for its setting. Under this premise, the construction of a detached house is carried out, subjecting the use and location of the house to the plot’s geometry and adapting it both to the site’s orientation and the views. We propose architecture of territory, that the presence of our construction impels us to imagine the place where it is erected. A building that seems to be strongly rooted in the ground, that give us the impression of being a natural part of its environment. As Peter Zumthor says in his book Thinking Architecture: “It awakens all my passion to project buildings that, with the passage of time, remain anchored in this natural way with the form and history of the place where they are located
