Abstract: The solar heat cutting performance of double-skin facades was analyzed in this paper. A physical model was built to calculate the thermal characteristics of double-skin facades. The effects of location, floor height, facade facing direction, blind slice angle, and skin style on solar heat cutting were investigated. The results show that double-skin facades can effectively cut the heat flux entering room, especially for west facing facade. Comparing with the single-skin facade, the double-skin facade cuts 1410.2 Wh/m2 more heat to enter room for west facing facade in a clear summer day in Nagano, Japan. Floor height mainly influences the outlet air temperature of the facade intermediate space, but not the heat fluxes. Locations somewhat affect the solar fluxes on outer facade surface.
