| 摘 要： | 以西安地区为例,利用能耗模拟程序对不同风向投射角对建筑组团热环境的影响进行了研究。采用依次改变建筑组团朝向与风向之间夹角的方法,建立了适合不同季节要求的算例模型。以全年建筑物能耗最低为判据,定量地阐述了风向投射角对建筑物能耗的影响。研究得到了西安地区建筑组团布局朝向的推荐方案:当建筑物的风向投射角在30度时,建筑物能耗最低;风向投射角在45度或逆时针旋转在15度范围内,建筑物能耗比较稳定。

| Abstract: | This article,taking Xi'an for a representative city,conducts a study of how different wind projecting angles influence the thermal environment by means of the simulator program of energy consumption.By sequentially alternating the included angle between the orientation of building cluster and wind direction,it sets up different arithmetic example models which can meet the requirements of various seasons.It also quantitatively expounds the impact of wind projecting angle on energy consumption of buildings wi... |
