摘要
给出了我国建筑运行能耗现状,并按照北方城镇建筑采暖、长江流域住宅采暖、住宅用能、非住宅建筑用能以及农村民用建筑用能的分类方法,分别分析了各类建筑能耗的特点、问题和节能的主要途径,同时对比了发达国家同类建筑用能与我国的差别。在基于数据和实际现象的分析的基础上,提出我国建筑能耗显著低于发达国家的主要原因是由于不同的生活方式和建筑使用模式所致,而维持目前这种相对节约的建筑使用方式与生活模式是实现我国建筑节能目标的基础。不同的生活方式和建筑使用方式需要不同的技术措施去实现节能,因此我国一定要采用与发达国家不同的技术途径来实现建筑节能目标。
The state of current China building energy use is presented.It is classified into the energy for space heating in North urban buildings,energy for space heating in Yangtze River area,energy for urban residential buildings,energy for non-residential buildings as well as energy for rural residential buildings.The characters,problems and key points for saving energy for each classification above were discussed in detail.Comparison with real building energy data in developed countries was also made in order to get clear idea on current China building energy state.It shows that current China building energy use is much lower than developed countries whatever in terms of per capita or in terms of building floor area.This is mainly due to the different lifestyles and different modes of building use.It is important to maintain the thrift mode in China in order to achieve the Chinese building energy conservation target.This should be the start point to design Chinese building energy strategy.As different lifestyles and different building use modes do need different technique measures,we should develop our own approach to realize their low building energy use target rather than follow the approaches that what happened in the developed countries.
