夏热冬冷地区不同玻璃类型幕墙对建筑能耗影响的模拟分析

近年来,玻璃幕墙特殊的建筑美学效果,受到了建筑师的喜爱,而大量公共建筑采用玻璃幕墙作为其外围护结构造成了巨大的建筑能耗问题.本文以自行建立的一栋2层展览中心为物理模型,模拟了不同玻璃类型条件下的设计日负荷、月运行总能耗和全年运行总能耗.结果表明,不同玻璃类型对建筑能耗影响很大,吸热玻璃对冬季热负荷节能效果较好,热反射玻璃对夏季冷负荷节能效果较佳,Low-E玻璃对冷热负荷的节能潜力均较好.

Simulation Analysis on Influences of Glass Curtain Wall with Different Glass Types on Building Energy Consumption in Hot Summer and Cold Winter Zone

Recently,due to the special architectural aesthetics,glass curtain wall is widely used,which lead to tremendous energy consumption.In this paper,a two-storey exhibition center with glass curtain wall was taken as a simulation model,the parameters,such as design load,monthly and annual energy consumptions were calculated.The results demonstrated that different types of glasses had great influences on building energy consumption.For example,the heat absorbing glass had better effect in winter than in summer,t...
