对重庆商场建筑外墙保温节能设计措施的探讨

Study on the Heat Preservation and Energy Efficiency Design of Exterior Wall of Store Building in Chongqing

为深入研究公共建筑的节能潜力与节能设计措施,选择重庆市区大型商场建筑为研究对象。在调研了主要的商场建筑的基础上,建立了商场建筑基本模型;针对商场建筑外墙部分,从提高外墙保温隔热性能方面制定出采用双层玻璃窗、增加外墙保温层及空气间层等四种不同的节能构造设计方案,并分别与现状外墙的能耗状况进行对比研究;通过比较各方案的热工性与经济性指标,得出商场建筑外墙节能设计的有效措施,为大型公共建筑的节能设计提供参考。

In order to research the potential of energy efficiency design of public building in depth, the large scale of store building in urban districts of Chongqing is chosen as the subject. On the basis of investigation into typical department store,an elementary model of department store has been built up. In allusion to exterior wall of department store, in respect of improving heat preservation of exterior wall, four different energy efficiency conformation design projects were made out,such as using double-layer window and adding heat insulation layer to exterior wall etc. and four energy efficiency projects with the actual design of exterior wall were compared;By analyzing the thermal and economic indexes, the most effective project of the energy efficiency design of exterior wall as to store building was found out to provide reference to the energy efficiency design of large scale of public building.
