The Design And Analysis About Saving-energy On Building In Cold Area

At present, the energy problem has been a hot issue in the world. And saving energy in buildings has become to a great important issue since the buildings spent a large portion of all energy.In China, with the accelerated proceeding of urbanization and the development of GDP, the house industry developed with a high speed in recently years.Although the government made serval laws and many rules on saving energy, the result is not optimistic now. The mainly reason is that the buildings were not designed with saving energy techniques as one necessary part. This paper talked about the energy consumption of the heating in the winter and the conditioner in the summer in north area of China from two aspects of saving energy technology and new energy ultilization. And this paper indicates the techniques to reduce the energy consumption in design stage by simulating the heat consumption of the example buildings with vary area ritio of window to wall and vary shape coefficient of building.At the end of the paper, the author brings forward some suggestions on spreading of the saving energy buildings.
