采用 DeST-h 软件对兰州地区一栋住宅楼进行了全年采暖能耗逐时模拟,研究外窗传热系数,遮阳系数和窗墙比对住宅建筑能耗的影响。通过模拟计算,得出了不同朝向房间的全年累计负荷指标随窗墙比的变化规律,以及不同外窗传热系数的相对节能率。
採用 DeST-h 軟件對蘭州地區一棟住宅樓進行瞭全年採暖能耗逐時模擬,研究外窗傳熱繫數,遮暘繫數和窗牆比對住宅建築能耗的影響。通過模擬計算,得齣瞭不同朝嚮房間的全年纍計負荷指標隨窗牆比的變化規律,以及不同外窗傳熱繫數的相對節能率。

The energy consumption of a typical design of a building in Lanzhou was simulated by the software DeST-h to gain the changing regulation of rooms load index with different window-wall ratio, shading coefficient and the heat transfer coefficient. Research shows that the optimal window-wall ratio is 0.5 in the south orientation. In the other orientations, the smaller radio of window-wall could assure less energy consumption.
