节能减排已成为我国的基本国策。近年来我国建筑规模增长迅速,每年新建建筑达20亿平方米以上,相当于全球建筑总量的40%。同时,建筑能耗占全社会的比重也以每年1%的速度增长,已从1 995年的11%提高到2005年的27%左右。随着城市化的进程不断加快,大型公共建筑的能耗问题已日益突出,国家在“十一五”、“十二五”规划中都将大型公共建筑的节能工作放到了重要
Energy-saving emission reduction has become China’s basic national policy. In recent years, the scale of China’s construction has been growing rapidly, with more than 2 billion square meters of newly-built buildings each year, equivalent to 40% of the total global construction. At the same time, the proportion of building energy consumption in the whole society has also increased by 1% annually, from 11% in 1995 to 27% in 2005. With the accelerating process of urbanization, the energy consumption problem of large-scale public buildings has become increasingly prominent. In the 11th Five-Year Plan and the 12th Five-Year Plan, all countries put major energy-saving work on public buildings under control
