窗墙比对居住建筑能耗的影响

以居住建筑为对象，研究窗墙比对能耗的影响规律。结果表明，对夏季空调能耗影响程度最小的是北向窗墙比，南向窗墙比的影响程度最大；北向窗墙比对冬季采暖能耗影响程度相对较小，且随着窗户保温性能的增强．这种影响将会更小，甚至有利于减小冬季采暖能耗；在模拟条件下，当南向窗墙比为0．3时，居住建筑全年总能耗最小。窗墙比对冬季采暖能耗的影响程度与窗的类型有关，对总能耗的影响程度与窗的类型基本无关。

INFLUENCE OF WINDOW-WALL RATIO ON ANNUAL ENERGY CONSUMPTION IN RESIDENTIAL BUILDINGS

Taking residential buildings as object, studies the influence of window-wall ratio on the energy consumption. The results show that the influence of north window-wall ratio on energy consumption for air-conditioning is the smallest, and which of the south one is the greatest. The influence of north window-wall ratio on energy consumption for heating is relatively small. In the simulated situation, with the south window wall ratio of 0.3, the total consumption is the smallest. The influence of window-wall ratio on heating energy consumption is related with the type of window , and it is not basically related with the window type on the total energy consumption.
