我国是个能源消耗大国。与国外相比我国的单位建筑能耗是同等气候条件下发达国家的3倍,建筑节能是我国建筑业发展的必然趋势。目前我国大多数建筑无保温节能措施,建筑的高耗能已经给社会带来了沉重的负担。 Our country is a big energy consumer. Compared with other countries, China’s building energy consumption is three times the developed countries under the same climate conditions, building energy efficiency is the inevitable trend of China’s construction industry. At present, most buildings in our country have no measures of thermal insulation and energy saving, and the high energy consumption of buildings has brought a heavy burden to the society.
