夏热冬冷地区居住建筑外遮阳设计探讨

Exterior Sunshade Design of Residential Building in Hot Summer and Cold Winter Zone

夏热冬冷地区的居住建筑产生的建筑能耗主要为夏季空调能耗。对建筑外窗采取遮阳措施,夏季能降低空调能耗。从建筑节能角度看,采用外遮阳比采用内遮阳更能降低夏季空调能耗。针对夏热冬冷地区的地理位置和气候特点,结合建筑朝向,对居住建筑外遮阳设计进行了探讨。

The energy consumption of air-conditioning in summer is the main part of the whole residential building energy consumption in hot summer and cold winter zone. Taking sunshade measures for external windows of buildings may reduce air-conditioning energy con- sumption in summer. From the perspective of building energy efficiency, using external sunshade can reduce more energy consumption of air- conditioning in summer than using internal sunshade. Various exterior sunshade designs are expounded considering the building orientation, location and climate characteristics in hot summer and cold winter zone.
