研究背景目前我国建筑能耗约占全社会终端能耗的27.5%,随着我国城镇化进程的进一步发展,建筑总量不断增加,建筑能耗总量和占全社会能耗的比例都将持续增加,因此,建筑节能意义重大。根据住建部公布的《“十二五”建筑节能专项规划》,到2015年全国城镇新建建筑执行标准不低于65%的建筑节能标准,城镇新建建筑95%达到建筑节能强制性标准的要求,鼓励北京、上海、天津、重庆4个直辖市和
Research Background At present, China’s building energy consumption accounts for about 27.5% of the total energy consumption of the whole society. With the further development of urbanization in our country, the total amount of buildings increases continuously, and the proportion of total building energy consumption and total energy consumption of the whole society will continue Increase, therefore, building energy saving is of great significance. According to the “Twelfth Five-Year Plan” for Building Energy Conservation issued by the Ministry of Housing and Urban-Rural Development, by 2015, the building energy efficiency standard for new construction in cities and towns in China will not be lower than 65%, and 95% of new buildings in urban areas will meet the compulsory standard for building energy efficiency Requirements, encourage Beijing, Shanghai, Tianjin, Chongqing and four municipalities
