大连某既有居住建筑墙体节能改造

The Energy Efficiency Retrofit of A Existing Building in Dalian

墙体外保温是节能建筑墙体保温的主要方式,尤其适用于既有建筑墙体节能改造。从经济、结构安全、节能的角度对外保温墙体进行分析计算,给出确定保温层厚度的方法和计算公式。并结合大连某既有建筑节能改造工程,对墙体热稳定性进行动态分析。

External insulation wall is the main insulation wall method, especially suitable for the retrofitting of the existing building. The thermal performance basing on the economic, construction safety and energy effciency of the external insulation wall was analyzed, and the method and formula of determining the thickness of the insulation were put forward. The thermal stability of wall was analyzed combing with the demonstration project in Dalian.
