摘要
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。
Aiming at the problem of building shading effect on building energy consumption, numerical simulation method was adopted in this paper, and studies were conducted on representative south-facing horizontal shading device. With the controlling variable method, the effect of different window-wall ratio, window type and visor length on energy consumption for air conditioning and heating in five different climatic regions were analyzed, and the influence law of different south-facing window-wall ratio, window shading coefficient, visible light transmittance and visor length on building energy consumption for air conditioning and heating in five climatic regions was achieved, as well as the reasonable matching relationship between south-facing window-wall ratio, window type and horizontal visor length, which contributes to building energy efficiency design.
