夏热冬冷地区百叶外遮阳对建筑能耗及眩光的影响
Effect of exterior louvers on building energy consumption and glare in hot summer and cold winter zone
摘要：
以南京某办公建筑为例，采用EnergyPlus软件对南向和西向不同百叶开启度对各季节建筑能耗及眩光的影响进行了模拟。结果表明：南向外窗春、夏、秋、冬各季节百叶最优开启度分别为70°~130°，60°，60°，80°；西向外窗各季节百叶最优开启度分别为60°，40°，60°和120°；与无遮阳相比，外窗百叶在不同季节采用最优开启度时，全年总能耗的减少率南向和西向分别为13%和23%，全年眩光时间的减少率南向和西向分别为96%和94%。
Abstract：
Taking an office building in Nanjing as an example, simulates the influence of different slat angles in the south and west oriented facades on the building energy consumption and the glare in various seasons by the EnergyPlus software, respectively. The results show that the optimal slat angles are 70° to 130°, 60°, 60° and 80° for the south oriented facade in spring, summer, autumn and winter, respectively, and 60°, 40°, 60°, 120° for the west oriented facade, respectively. Compared with non-shading, the reduction rates of annual energy consumption are 13% and 23% and the reduction rates of annual glare time are 96% and 94% for the south and west orientation, respectively, with the facades optimal slat angles in various seasons.
