一、引言十一届三中全会以来,我国住宅建设突飞猛进,城镇每年新增住宅1亿多 m~2,建筑能耗(包括建筑材料的生产运输,建筑物的建造和使用等的能耗)也随之迅速增长。据统计,建筑能耗在我国总能耗中所占的比重已达到27%(西方发达国家为33～42%),从80年代初起,建筑节能已列为我国节能的重 I. INTRODUCTION Since the Third Plenary Session of the 11th CPC Central Committee, China’s housing construction has advanced by leaps and bounds, with more than 100 million m~2 new residential buildings per year in cities and towns, and building energy consumption (including energy consumption from the production and transportation of building materials, construction and use of buildings). It also grew rapidly. According to statistics, the proportion of building energy consumption in China’s total energy consumption has reached 27% (33% to 42% in Western developed countries). Since the early 1980s, energy efficiency in buildings has been listed as a priority for China’s energy conservation.
