Cooling load reduction effect in slim double skin facade (SDSF)

Abstract

Abstract The office building consumes cooling energy in the summer season. Building envelope such as different windows affects the indoor heat gain. Operation of the cavity in double skin façade (DSF) is widely used passive design and can reduce the cooling load. Many cases have applied a building envelope. However, increase the initial investments affect the interruption of the application of the DSF. Hence, this paper investigated the slim double skin façade (SDSF) for cooling load reduction effect of the ventilation cavity. Heat balance analysis was conducted using EnergyPlus to investigate a heat transfer mechanism for SDSF. Finally, based on the analysis, SDSF can significantly reduce the cooling load in the office building in the lower cost than other DSF types.
