Study On Energy-saving Design For Passive House Envelope In Cold Region

Type along with our country economy and industrial structure adjustment, the development of the urbanization and human pursuit of high content of architectural space, the current social terminal energy consumption accounts for 20% of the proportion of building energy consumption will rise to 30% ?40%. During the 12th five-year plan,the building energy conservation and green building laws and regulations to form a system, and to the general public, in collaboration with the German passive ultra low energy consumption building experiment is a success. As much starker choices-and graver consequences-in planning during the research category of energy-saving building and one of the important development direction, in the cold region of passive low energy consumption building energy-saving rate is as high as 90%, compared with other types of energy saving building energy saving 85%. Passive ultra low energy consumption building adopting thermal bridge building palisade structure, and through the related technical structure to improve building thermal insulation performance and air tightness, in order to achieve the purpose of reduce the demand for heating and cooling buildings, and through the natural ventilation and lighting, solar radiation and indoor human activities passive means such as heat source, reduce or cancel the mechanical system of energy consumption.As you can see, from the connotation of passive ultra-low power consumption in the cold region passive ultra-low energy consumption of residential building energy efficiency design in the importance of retaining structure, with reasonable methods for energy saving design of retaining structure, to reduce the construction demand for energy. This article mainly through to the cold area residential building energy consumption characteristics analysis, the passive ultra-low energy consumption of residential building palisade structure corresponding energy saving design measures are put forward.Full text main content is divided into the following several parts: first of all browse through passive ultra low energy consumption building related literature and browsing information, thus to interpretation and its related concepts, and introduces the passive low energy consumption building, cold area, residential building, palisade structure part of the four basic theories and research status at home and abroad. Secondly, through the analysis of the influence factors of palisade structure design, for the energy-saving design of ultra-low power passive building palisade structure provides the basis of the relevant guidance. And according to the retaining structure of entities outside the walls,roof,floors,doors and Windows of different characteristics, analysis of cold region passive energy-saving design of low energy consumption residential building palisade structure and put forward their views. Finally through to the already built and was not built in a cold region passive ultra-low energy consumption of residential building energy-saving design of retaining structure analysis,summed up the cold region passive ultra-low energy consumption of residential building energy-saving design of retaining structure, and puts forward the corresponding improvement measures, hope to be able to cold area in the future passive energy-saving design research of low energy consumption residential building palisade structure to provide relevant reference...
