窗墙比对住宅供暖空调总能耗的影响
Influence of windowwall ratio on annual energy consumption for heating and air conditioning in residential buildings
摘要：
以上海地区的居住建筑为研究对象，采用DeST软件对建筑全年的供暖、空调能耗进行了动态模拟，研究分析在不同朝向下，窗墙比对建筑全年供暖能耗、全年空调能耗以及全年供暖、空调总能耗的影响规律。结果表明，东（西）、北向窗墙比的加大会导致建筑全年供暖、空调总能耗的增加；在夏季采用外窗遮阳和有效夜间通风的条件下，南向窗墙比的加大有利于建筑全年供暖、空调总能耗的降低。

Abstract：
Dynamically simulates the annual energy consumption for a typical residential building in Shanghai using DeST software, and studies the influence of windowwall ratio in different building orientations. The results show that the total energy consumption for heating and air conditioning will increase with the greater east (west) or north windowwall ratio and that the total energy consumption will be reduced with the greater south windowwall ratio on condition that window shading and night ventilation in summer.
