外窗在建筑的围护结构中是非常重要的部分,从建筑物耗热量来看,窗的传热耗热量加上窗的空气渗透耗热量约占全部建筑耗热量的50%左右,由此可见,外窗是耗热量最大的地方,也是我们建筑节能设计的重点部位。提高建筑物外窗的保温性和加强外窗的气密性,是建筑节能的关键措施。在实施居住建筑节能65%设计标
Outside the window in the building envelope structure is a very important part of the building from the heat consumption point of view, the window heat transfer plus window heat consumption of air consumption accounts for about 50% of the total building heat consumption, we can see that , Outside the window is the place where the largest amount of heat, but also our building energy-saving design of the key parts. Improve the insulation of the outer windows of the building and strengthen the air tightness of the outer window, is the key measure of building energy efficiency. 65% in the implementation of residential building energy-saving design standard
