基于被动式超低能耗建筑需求的建筑门窗节能性能研究

Energy Conservation Performance of Doors and Windows Based on Demands of Passive Ultra-low Energy Building

针对制约我国建筑节能性能提升的门窗系统,基于典型气候区被动式超低能耗建筑需求,参考德国节能门窗做法,从型材材质选择及腔体截面优化设计、不同气候区节能窗玻璃系统配置、窗系统密封材料性能基本要求、五金系统等配套材料的选择、不同窗型对整窗传热系数的影响、节点做法等方面,探索实现我国门窗节能性能提升的途径。

Concerning the problem of the door and window system restricting the improvement of building energy efficiency in China,demanding for passive ultra-low energy buildings based on typical climatic zones,and refering to the German energy-saving doors and windows approach,authors start from the following aspectsto explore ways to achieve energy-saving performance of doors and windows in China:1)Selecting material of the profile and optimizing its cavity section;2)Choosing energy-saving window glass system configuration in different climate zones;3)Determining the basic requirements for the performance of the window system sealing material;4)Expliciting selection of supporting materials such as hardware systems;5)Finding the influence of different window types on the heat transfer coefficient of the whole window;6)Node arrangement,etc.
