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-power building is an important trend in the development of energy-efficient buildings in China. The applicable index of heat transfer coefficient of exterior windows is the basis of the design of exterior windows with passive ultra-low energy consumption. However, there is still a lack of relevant research in China at present. Based on the reference to the design criteria of passive exterior windows in foreign countries, this paper focuses on the method of determining the heat transfer coefficient of passive windows for passive ultra-low energy buildings and the index value of heat transfer coefficient of typical climate regions. For domestic passive ultra-low energy buildings The design of the product with a window has a certain reference value.
