摘      要：This paper attempts to resolve the reported contradiction in the literature about the characteristics of high-performance/cost-effective fenestration of residential buildings,particularly in hot *** considered issues are the window glazing property(ten commercial glazing types),facade orientation(four main orientations),window-to-wall ratio(WWR)(0.2–0.8),and solar shading overhangs and side-fins(nine shading conditions).The results of the simulated runs reveal that the glazing quality has a superior effect over the other fenestration parameters and controls their effect on the energy consumption of residential ***,using low-performance windows on buildings yields larger effects of WWR,facade orientation,and solar shading than high-performance *** the WWR increases from 0.2 to 0.8,the building energy consumption using the low-performance window increases 6.46 times than that using the highperformance *** best facade orientation is changed from north to south according to the glazing *** addition,the solar shading need is correlated as a function of a window-glazing property and *** cost analysis shows that the high-performance windows without solar shading are cost-effective as they have the largest net present cost compared to lowperformance windows with or without solar ***,replacing low-performance windows with high-performance ones,in an existing residential building,saves about 12.7 MWh of electricity and 11.05 tons of CO_(2) annually.
