建筑能耗占社会总能耗的近40%,其中门窗的能耗约占建筑能耗的50%,且主要是使用能耗,建筑门窗在实际应用和节能上表现出面积小、作用大、持续时间长的特点,可见门窗节能的特别重要性。门窗节能,牵涉到一个大国家建设低碳社会和低碳经济的责任;门窗节能,也牵涉到我们人类社会进入低碳文明所要付出的努力。
Building energy consumption accounts for nearly 40% of the total social energy consumption, of which the energy consumption of windows and doors accounts for about 50% of the building energy consumption, and the main use of energy consumption, building windows and doors in the practical application and energy saving showed small area, Long duration of the characteristics, we can see the special importance of energy saving windows and doors. The energy saving of windows and doors involves the responsibility of a large country to build a low-carbon society and a low-carbon economy. Energy-saving windows and doors also involve the efforts we must make to bring humanity into a low-carbon civilization.
