摘要：我国每年有10亿平方米的民用建筑投入使用，建筑能耗占总 能耗的比例已从1978年的10%上升到目前的30%左右。大力发展节能型建 筑已成为共识。当前，建筑节能问题已经成为全关注的热点。建筑保温是 建筑节能的重要组成部分，我国常用的建筑外墙保温技术有外墙内保温和 外保温。前者的显著特点是操作灵活，施工简单且造价低，不足之处是其 结构热桥使局部温差过大导致结东现象的发生。而外墙外保温的优势在于 其保温效果很好，适用范围广，可应用于旧楼改造等。随着外墙外保温技 术逐渐被应用到建筑之中去，外墙外保温设计工作至关重要，设计工作质 量的好坏直接影响建筑物施工质量的好坏，因此需要引起高度重视。

Abstract: China every year with 1 billion square meters of civil building put into use, total energy consumption of building energy consumption ratio has risen from 10% in 1978 to about 30% now. Vigorously develop energy-saving building has become a consensus. At present, building energy efficiency problem has become the focus of all. Heat preservation is an important part of building energy efficiency in our country, the commonly used exterior insulation technology have sold the exterior wall insulation mild. The former remarkable characteristic is flexible operation, simple construction and low cost, the deficiency is its structure thermal bridge so that local temperature difference in "too big east happens. And the external wall thermal insulation
，s advantage is its heat preservation effect very good, wide range and can be used in the old building reform, etc. Along with the external wall thermal insulation technology has been applied to the construction of gradually, exterior insulation design work is important, the quality of the design wor
