Research On Correct Factor Of Envelope K Factor For Energy Efficiency Resident Building In Tibet

Energy sources are the base to develop economy. With the Great Chinese west developping policy, the Tibet has having a rapid progress in city economy and the Energy requirement is keeping increase. Tibet is poor in Energy sources and be frail in entironment sources. Energy building has double signalities for economic developping and entironment protectting in Tibet.In China, the present Energy building design Code has some blankness in Tibet. The most important one is the the present Energy building design Code has no Solar Correct Factor of Building Structure for Tibet . Without the factor, we can not design the Energy building in Tibet based on the present Energy building design Code.Tibet has very rich solar energy in China and even in the word. In China, Tibet is the only place that need heating in winter and need no air cooling in summer with the reason of the special high land climate in it.The rich solar energy is a very useful factor for building to save heating energy in winter.With this paper, the result of our research will solve the blankness in present Energy building design Code, improve the Code, support and serve the Energy building designing in Tibet .First, we analyse our locale test result taken in winter, get the idea the rich solar radiation affect the heating energy saving very much in winter.Then, we analyse the typic year weather data of the typic city Lhasa in Tibet . We compare the data of Lhasa with that of Xian and Beijing which are the typic cities in the Chinese upcountry part. We find the great differences between them with the data.Second, we base on present building energy analyse theoreticses enough,with the full year 8760 hours calculate method on both Building...
