多年来,我国在建造房屋时,为了多建房,控制的是一次性投资,对于建筑物围护结构仅考虑满足结构安全及其内表面不结露的低标准要求,很少,甚至不考虑长期使用中的经常性支出,特别是采暖能耗。因此,建筑物围护结构的保温性能普遍较差,甚至有相当一部分建筑物围护结构不能满足内表不结露的低标准,房间热环境质量很差给居民的身体健康和财产带来一定的损害,并浪费了大量的采暖和空调能耗。同气候条件大体相同的发达国家和地区相比,单位建筑面积的采暖能耗比发达国家高2～3倍,既浪费能源又污染环境。由于能
Over the years, our country in the construction of housing, in order to build more housing, control is a one-time investment, for building envelope only consider the structural safety and non-condensing on the inner surface of the low standards, with little or no consideration Long-term use of recurrent expenditure, especially heating energy consumption. Therefore, the building envelope insulation performance generally poor, and even a considerable part of the building envelope structure can not meet the low surface of the table does not dew, poor thermal environment in the room to residents of the health and property to certain The damage and wasted a lot of heating and air conditioning energy consumption. Compared with developed countries and regions with roughly the same climatic conditions, the heating energy consumption per unit of building area is 2 to 3 times higher than that of developed countries, which is not only a waste of energy but also pollutes the environment. Because of it
