我国被动式超低能耗建筑用外窗传热系数指标研究

被动式超低能耗建筑是我国节能建筑发展的重要趋势,适用的外窗传热系数指标是被动式超低能耗建筑用外窗设计的基础,但目前国内尚缺少相关研究。本文在参考国外被动式建筑用外窗设计准则的基础上,重点探讨了国内被动式超低能耗建筑用外窗传热系数的确定方法及典型气候区传热系数指标值,对于国内被动式超低能耗建筑用外窗产品的设计具有一定的参考价值。

Passive ultra low energy consumption building is an important trend in the development of energy saving building in China.Thermal transmittance index of external window is the basis for the design of passive ultra low energy consumption buildings,but there is still a lack of relevant research.On the basis of reference to the design criterion of external windows for passive buildings,this paper mainly discusses the method of determining the thermal transmittance of external window and the value of thermal transmittance in the typical climate zone,which has certain reference value for the design of passive ultra low energy consumption buildings.
