夏热冬冷地区办公建筑自然采光效果模拟分析

选取夏热冬冷地区苏州市某办公建筑作为模拟对象,采用Ecotect结合Radiance软件模拟建筑内自然采光情况,计算建筑内各楼层的平均自然采光系数与全自然采光百分比,分析玻璃可见光透射比、窗墙比对建筑自然采光效果和照明能耗节约量的影响。研究表明,采用可见光透射比较高的玻璃,适当增加建筑外窗面积,有助于提高建筑采光系数,改善自然采光环境,节约建筑照明能耗。

Simulation and Analysis of Office Building Daylight Effects in Hot Summer and Cold Winter Zone

An office building in Suzhou is selected as the simulation object in hot summer and cold winter zone. The daylight conditions indoor is simulated using Ecotect and Radiance. The average daylight factor and daylight percentage of every floor in this building are calculated. The influences on daylight effects and lighting energy savings caused by glass visible light transmittance and window-wall ratio are analyzed. The research results show that higher glass visible light transmittance and window area are helpful for enhancing the building daylight factor, which can improve the daylight environment and reduce the lighting energy consumption.
