装配式建筑外围护结构节能技术研究综述

Review on Energy-saving Technologies of Prefabricated Building Envelope

围护结构是建筑的重要组成部分,也是装配式建筑节能研究的技术热点和难点。目前国外的装配式建筑围护结构节能研究对象多为复合结构,研究内容更加多元化;而国内研究仍旧以单种结构为主,针对装配式建筑热工性能与节能技术的研究相对匮乏。本文对国内外装配式建筑外围护结构不同构造节能体系研究现状进行综述,并指出我国未来应重视混合构造形式的本土化节能设计研究,且应根据各气候分区气候环境特点确定具有最佳节能效果的外围护构造体系。

The envelope is the important part of the building.Therefore,it has always been a technical hot-pot in the research of energy conservation on prefabricated buildings.In the current foreign literature,the research object of energy saving on prefabricated building envelope structure is mostly composite structure,and the research content is more diversified.however,domestic research is still dominated by single structure,and research on thermal performance and energy-saving technology of prefabricated buildings is relatively scarce.This paper summarizes the research status of different structural energy-saving systems of the outer envelope of prefabricated buildings at home and abroad,and points out that China should pay more attention to the localized energy-saving design of mixed structural forms in the future,and the outer envelope structural system with the best energy-saving effect should be determined according to the climatic environment characteristics of each climate zone.
