窗户的采光性能对建筑的照明能耗有重要的影响.对于办公建筑,照明能耗占建筑总能耗的比重较大,因此,窗户的采光性能对建筑能耗的影响就更加重要. 窗玻璃的可见光透过率是影响窗户采光性能的重要因素.为了单独分析窗玻璃可见光透过率的影响,以一栋实际的办公建筑为基础,采用eQuest软件建立建筑模型,对Low-E中空玻璃的3种最常用的类型进行分析,这3种Low-E中空玻璃具有相同的遮阳系数和传热系数,但是其可见光透过率不同.分析结果表明:考虑窗户的采光对建筑的照明能耗有重要的影响,达到30%;三银Low-E中空玻璃采光性能最好,节能效果优于单银Low-E中空玻璃和双银Low-E中空玻璃;对于办公建筑,选择建筑玻璃时,应考虑玻璃的综合性能,选择系数r是重要的考量.

Thedaylightingperformanceofthewindowsisofimportantinfluenceonbuildinglighting energy consumption. In the office building, the lighting energy consumption accounts for the main propor-tion of total energy consumption, so the influence of daylighting performance of windows on building lighting energy consumption becomes more important. The visible light transmittance of window is one im-portant factor that affects the window lighting performance. In order to analyze the effect of window visi-ble light transmittance separately, on the basis of an actual office building, three common kinds of Low-E insulating glass are analyzed by establishing architectural model with eQuest software. The three kinds of Low-E insulating glass are of the same shading coefficient and heat transfer coefficient, but the visible light transmittance are different. Analysis results show that the daylighting of the windows is of important influence on building lighting energy consumption, reaching 30%, which is considered; The lighting per-formance of three silver Low-E insulating glass is best, therefore, its energy saving effect is better than that of single silver Low-E insulating glass and double silver Low-E insulating glass; For office buildings, when choosing construction glass, comprehensive performance of glass should be considered, and selecting coefficient r is crucial.
