摘　　要：百叶遮阳可以有效控制进入办公建筑内的太阳辐射,合理利用太阳光不仅可以改善室内的光热环境,还可以降低室内的综合能耗.利用EnergyPlus软件建立了1个标准房间模型,选择青岛作为模拟地点,模拟了5种不同角度百叶外遮阳下该房间分别在冬季南向和夏季西向的光热环境及综合能耗.通过对模拟结果的分析与比较得出:对于夏季西向房间,30,60,90°百叶角度下光环境较优,30,60°百叶角度下热环境较优,30°百叶角度下综合能耗更低;对于冬季南向房间,30,60,90°百叶角度下光环境和热环境均较优,120°百叶角度下综合能耗更低.The blind sunshade can effectively control the solar radiation entering the office building,and reasonable use of sunlight can not only improve the indoor thermal environment,but also reduce the indoor comprehensive energy consumption.This article uses EnergyPlus software to establish a standard room model,chooses Qingdao as the simulation location,and simulates the light and thermal environment and comprehensive energy consumption of the room in the south in winter and west in summer under the sunshade of 5 different louver angles.Through the analysis and comparison of the simulation results,it is concluded that for the west-facing room in summer,the light environment is better at 30,60 and 90°of louver angles,the thermal environment is better at 30,60°of louver angles,and the comprehensive energy consumption is lower at 30°of louver angle.For the south-facing rooms in winter,the light environment and thermal environment are better at 30,60 and 90°of louver angles,and the comprehensive energy consumption is lower at 120°of louver angle.
