据资料报导,工业发达国家建筑耗能占总耗能的30%以上,因此,他们在建筑设计、施工以及建成投产阶段如何节能做了大量工作,制定节能措施,采取经济手段,并用立法的形式保证建筑节能工作的顺利进行.这些国家都把节能看成建筑技术政策的一个重要课题.随着房屋建筑特别是住宅建筑的不断增加.我国采暖耗能量正直线上升,而且,完全可以预料.今后还将大幅度继续上升.采暖用能的矛盾将愈益尖锐,因而认真分析采暖用能的各个环节并找出节约的途径,进而采取切实可行的措施已是一项非常重要和紧迫的工作.
According to data reports, industrial buildings in developed countries account for more than 30% of total energy consumption. As a result, they have done a lot of work in building design, construction, and putting into production, energy saving measures, economic measures, and legislation. To ensure the smooth progress of building energy conservation, these countries regard energy conservation as an important issue in building technology policy. With the continuous increase in housing construction, especially in residential construction, the heating energy consumption in China is rising in a straight line, and it is entirely predictable. It will continue to rise substantially. The contradiction in energy use for heating will become more acute. Therefore, it is a very important and urgent task to carefully analyze all aspects of heating energy use and find ways to save energy, and then take practical measures.
