Abstract
The blinds in the intermediate space are installed to block the direct solar radiation. As the blind divide the airflow of intermediate space into two, thermal performance of Double-Skin Facade (DSF) are affected by the blind position. Therefore blind position should be planed with careful consideration in order to maximize the thermal performance of DSF. In this study, CFD was peformed to analyze the effect of blind position in multistory-type DSF in variation of other DSF elements. The simulation results showed that the case with narrow depth of intermediate space and outlet on upper side of outer-facade, it is profitable to place blind as close as possible to the outer-facade. In the other cases, the blind should maintain 0.15 m distance from outer-facade.
