This paper explores thermal and energy performance of double skin facades (DSFs) in different climate types, specifically focusing on three typologies: box window, corridor type and multistory DSFs. These systems were investigated and analyzed to answer the question of how the different DSFs perform in comparison to each other, as well as a typical curtain wall (single skin facade used as a baseline), in a multitude of climate applications. The utilized research methods included two-dimensional heat transfer analysis (finite element analysis), Computational Fluid Dynamics (CFD) analysis and energy modeling. Heat transfer analysis was used to determine heat transfer coefficients (U-values) …

This article discusses results of a research study that investigated daylight performance of glazed double-skin facades (DSFs) in various climate types. The objectives of the study were: 1) to analyze the daylight levels in different types of DSFs (box window, corridor type, and multistory) in four different climates; 2) to compare daylight performance against the conventional single skin glazed facade (curtain wall); 3) to investigate the effects of facade orientations on daylight; and 4) to investigate the impacts of facade characteristics (different depth of air cavities in DSFs) on daylight levels. The research methods consisted of daylight simulations in Radiance …
