摘要
针对上海地区冬季太阳高度角小、夏季太阳高度角大的地理特点,与夏热冬冷的气候特点,以减少建筑能耗为目标,用Ecotect软件建立一简化建筑模型,改变南向外窗的安装角度,通过数值计算和模拟分析,获得了有利于节能的外窗倾斜角度,甚至可以省去遮阳系统。
Aiming at Shanghai＇s geographical feature that the solar altitude-angle is small in winter and large in summer, and climatic feature that hot in summer and cold in winter, a simple building model was constructed by Ecotect software for reducing building energy consumption. Through changing its installation angle of south outer window, the slope angle which is benefit to energy conservation was obtained, even the sun-shading system can be saved.
