窗墙比对住宅供暖空调总能耗的影响

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。

Influence of window-wall ratio on annual energy consumption for heating and air conditioning in residential buildings

Dynamically simulates the annual energy consumption for a typical residential building in Shanghai using DeST software, and studies the influence of window-wall 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 window-wall ratio and that the total energy consumption will be reduced with the greater south window-wall ratio on condition that window shading and night ventilation in summer.
