Abstract

Abstract: This study investigates the effect of a perforated sheet combined with a double‐skin facade (DSPF) by varying the important building parameters, such as perforation percentage, facade orientation, and the thickness of the double‐skin facade (DSF). This study determines the energy‐saving, natural ventilation, and daylight performance of an office building in Tokyo, Japan by conducting simulations. This study discovers that the DSPF thickness does not influence the performances much and the DSPF thickness of 0.5 m is recommended. For daylighting, the system with the 40% perforation percentage on the south and 10% perforation percentage on the west is the best case of daylight access without disturbing glare in the particular view of this study. To balance natural ventilation and daylight when installing perforated screens, this research demonstrated the net heat removal in spring when the perforated percentage of 50% on the south and 30% on the west is recommended. In autumn, the net heat removal when the perforated percentage of 10% on the south and 30% on the west is recommended. This research demonstrated that the total net heat removal when the perforated percentage of 10% on the south and 30% on the west are recommended for removing heat throughout a year.
