Review of the Technique of Building Energy-Saving

The pace of building energy-saving in our country is late,compared with developed countries,the consumption of building energy is much higher.Therefore,It is imperative to open up new technique of building energy-saving and heighten the energy using efficiency.The technique approach of realizing energy-saving is to exploit greatly and use new reproducible energy when trying to reduce total energy demand in buildings,then it can reduce the utilization of energy which can easily lead to environment pollution in building realm.Reducing total energy demand in building mainly embarks from the following aspects,building programming and design,round safeguard structure,enhancing energy using efficiency of End-User and heightening total energy using efficiency.The utilization of new energy plays an important role in saving energy and protecting environment.In contrast with the past,building energy-saving puts forward higher requirement to building materials.Building materials play a very important role in building energy-saving.
