摘　　要：建筑能耗的75%是由围护结构传热造成的,围护结构施工质量直接影响净零能耗建筑的节能效果,应作为施工质量控制的重中之重。本文就建筑外墙、屋面、门窗等围护结构的材料选型、施工方法等进行分析,并对外墙保温、隔热及外遮阳系统进行总结,提出了一套净零能耗建筑的施工技术,为以后被动房建造提供经验与参考。The 75%of the building energy consumption is caused by the heat transfer of the building envelope.The construction quality of the building envelope directly affects the energy-saving effect of the net zero energy building,which should be the top priority of the construction quality control.This paper analyzes the material selection and construction method of the building envelope such as exterior wall,roof,door and window,summarizes the exterior wall system of heat preservation,heat insulation and external sunshade,and puts forward a set of construction technology of net zero energy building,which provides reference experience for the construction of passive housing in the future.
