深圳市某办公建筑水平百叶外遮阳优化分析

Optimizing Horizontal Louver Sun-shading for Office Buildings in Shenzhen

以深圳市某办公建筑为例,采用Ecotect软件分析了水平百叶外遮阳对建筑立面太阳辐射的影响。模拟结果得出了在不同板片倾角、不同的百叶中心离墙距离、不同朝向下的夏季太阳直射、散射、总辐射量的变化曲线。并对固定式水平百叶外遮阳的不同板片倾角和百叶离墙距离的模拟结果进行比较分析,得到最佳的百叶倾角和离墙距离,在此基础上提出该建筑的百叶遮阳的最优布置方案。

An office building in Shenzhen is researched as example. Ecatect is utilized to analyze the effect of horizontal louver sunshading to solar radiation on building elevation. The results of simulation show that the curves of incidence, diffuse and total solar radiation in different slat angles, various distances between wall and center of shading, different directions in summer season. Meanwhile, it compared and analyzed the simulation results at different slat angles and distances between wall and slat of fixed shading. The optioned slat angle and distance between slat and wall are obtained, proposing the optimization programs about horizontal louver sun-shading.
