针对建筑遮阳对建筑能耗的影响问题,以数值模拟为研究手段,选取具有代表性的建筑南向水平遮阳进行研究,采用控制变量法分别分析不同气候区的不同窗墙比、不同窗户类型、不同遮阳板长度对建筑空调采暖能耗的影响,得到了五个气候区建筑南向窗墙比、窗户遮阳系数和水平遮阳板长度对建筑空调采暖能耗的影响规律,找出了五个气候区建筑南向窗墙比、窗户类型、水平遮阳板长度之间合理的匹配关系,对建筑的节能设计起到了重要的指导作用。 In view of the influence of building shade on building energy consumption, taking numerical simulation as a research method, a representative south-facing level shade is selected to study. By using control variables method, different window-wall ratios, different window types, The influence of different sun visor length on heating energy consumption of building air-conditioning was studied. The influence of south-facing window-wall ratio, window shading coefficient and horizontal sun visor length on heating energy consumption of building air-conditioning were obtained in five climate zones. Five climates The reasonable match between the south-facing window-wall ratio, the window type and the horizontal sun visor length in the district building plays an important guiding role in the energy-saving design of the building.
