外墙外保温系统建筑设计

Architectural Design of Exterior Wall External Insulation

节约能源和环境保护是我国国策,因此建筑节能尤其是墙体节能应引起重视。建筑节能是一个系统工程,介绍了我国现行墙体保温标准体系和欧盟EOTA认证标准ETAG004的6项基本要求,提出外墙外保温系统设计主要注意事项,包括正确理解和使用规范标准、充分利用保温材料可塑性、加强抗风压设计、注意翻包构造及系统水蒸气渗透能力等。

Energy saving and environmem protection is national policy of China. Thus , energy saving of building must be paid more attention, especially for energy saving of walls as a system engineering. This paper introduces present standard system of energy saving of walls and six fundamental requirements in ETAG004 authenticated by ETOA European Union. Furthermore, it proposes main points for attention in the design of exterior wall external insulation such as understanding and using standards reasonably, making full use of plasticity of insulation materials, strengthening design of anti-wind pressure and paying more attention to flanging structure and vapor permeability of the system.
