摘要：

介绍了超低能耗建筑需重点关注外墙外保温系统耐久性的原因，并概述了提升外墙保温系统耐久性的设计方法和节点构造。通过调研多个已建成的超低能耗居住建筑项目，发现项目频繁出现管线与外保温系统碰撞、窗台板部位外保温系统面层开裂和雨水管支架出外保温系统面层出现大孔的质量问题，直接影响了外保温系统的耐久性。结合设计现状分析问题成因并提出了相关处置建议。

This paper introduces the reasons why ultra?low energy consumption buildings need to payattention to the durability of external wall insulation system. The design method and node structure for improving the durability of external insulation system are summarized. Through the investigation of several ultra?low energy consumption residential building projects that have been built, it is found that the external insulation system of the project frequently encounters the collision between the pipeline and the external insulation system, the cracking of the surface layer of the external insulation system at the window sill plate and the quality problems of the large holes in the surface layer of the external insulation system of the rainwater pipe bracket,which directly affects the durability of the external insulation system. Combined with the design status, the causes of the problems are analyzed and relevant disposal suggestions are put forward.
