建筑节能是当今社会的热点问题。在中国,建筑用能约占商品能供应总量的1/3,并且有逐年增长的趋势。目前,中国既有的建筑面积已经超过400亿平方米,预计至2020年,城镇建筑面积将增加150亿平方米,而由此增加的建筑能耗约为上亿吨标煤。由此可见,建筑用能将是中国节能潜力巨大的领域之一。
Building energy efficiency is a hot issue in today’s society. In China, building energy accounts for about 1/3 of the total supply of goods, and there is a trend of increasing year by year. At present, China has an existing GFA of more than 40 billion square meters. It is estimated that the urban construction area will increase by 15 billion square meters by 2020, and the construction energy consumption thus increased will be about 100 million tons of standard coal. This shows that construction energy will be one of the huge potential areas for energy saving in China.
