Study On Design Of Low Energy Consumption Residential Buildings In Plateau Alpine Region

Tibet plateau in China is located in the southwest border, where has it’s own climat, the residential buildings in the summer don’t need air conditioning system,but the winter need long heating. Solar energy resource is extra ordinarily rich in Tibet Plateau, while the conventional fossil energy is scarce and the unique entironment is very vulnerable. It’s an important measure to promote residential building’s sustainabled evelopment in Tibet that researehing low energy consumption residential building on heating residential building in winter with the abund antsolar energy resources. This paper studies based on the Tibetan plateau climate characteristics, To use the solar energy to improve plateau cold area of residential architecture indoor environment for the background, discusses how to optimize the design of the low energy consumption residential building.The Tibetan areas with climate represents mainly about:Lhasa,xigaze, changdu naqu,nyingchi and other regions. Each of the climate has its characteristics according to the difference between geographical position. In the Tibetan plateau, January is the most cold in every year, and xigaze has the strongest intensity of solar radiation in this month,it an reach20.20MJ/m2d;And average lowest solar radiation intensity is changdu in January, for11.59MJ/m2d. This article selected Lhasa which has the average level in the middle reaches of solar radiation, and economic and technical background better in other areas, the average solar radiation intensity of15.89MJ/m2d in January. In Lhasa,most of the time1can achieve75%above in the sunshine in winter and of the use of solar energy is very ideal.Specific include the following aspects:(1) With Lhasa as an example, combine the functions of the space and the Indoor environment improvement technology, put forward "Plateau low energy consumption and high altitude of housing design principle".(2) Analysis and determined the low energy consumption of residential building indoor environment standard, combined with the local building features to establish the physical model, as the foundation of the low energy building of the analysis and research.(3) From the different space and function of heat requirement, analyzed the low energy consumption in housing design of the status, based on this puts forward the indoor environment of the improvement plan.(4) The basis of energy-saving building representative of low energy residential building indoor environment is simulated and analyzed, determine the low energy consumption of the system of residential building scientific nature.
