兰州地区不同外窗对居住建筑能耗的影响

摘要

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。%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.
