中国既有建筑面积达420亿平方米,其中城市房屋建筑面积140.91亿平方米。新增建筑中超过80%的房子是高能耗建筑。既有建筑中,95%以上属于高能耗建筑,节能建筑面积仅为3.2亿平方米。细加分析不难发现,占建筑能耗60%的是采暖和空调,因此建筑节能的重点,应该锁定在采暖和空调方面。空调用能日益成为夏季用电高峰的关键因素。中国城市居民每百户空调器拥有量在2003年底平均已达61.8台,在公共建筑中的使用则更加普遍。炎夏季节,空调的使用形成城市用电负荷高峰,导致许多地方频频拉闸限电,2005
China has an existing building area of 42 billion square meters, of which urban housing construction area of 14.091 billion square meters. More than 80% of the new buildings are high-energy buildings. Existing buildings, more than 95% belong to high-energy buildings, energy-saving construction area of only 320 million square meters. Detailed analysis is not difficult to find, accounting for 60% of building energy consumption is heating and air conditioning, building energy efficiency, the focus should be locked in the heating and air conditioning. Air conditioning can increasingly become the key factor in summer peak. The number of Chinese urban residents per 100 air conditioners reached an average of 61.8 units by the end of 2003, and their use in public buildings is even more prevalent. In the summer season, the use of air conditioners resulted in the peak load of electricity in cities, leading to frequent power cuts in many places in 2005
