Abstract

The biggest challenge in building design is to optimize the use of natural energy to provide human comfort and consume less energy. Passive facade technologies have been developed with increased complexity for approaching comfort and sustainability aspects. This study discovers performances of a facade system which is an integration of double-skin facade and perforated screens. This study aims to utilize the double-skin perforated facades with air ventilation ports for buildings to optimize energy saving which is also improving daylight and natural ventilation in Japan. The study is based on building simulation software to analyze building performances. The daylight performances are calculated by simulating with DIVA. The natural ventilation and energy performances are simulated on Design Builder. The perforated screens to get daylight without glare is the screens with the perforated percentage of 40%. This research discovers that the perforated percentage of 50% is the optimum rate for balancing natural ventilation and daylight in spring when the weather across Japan is pleasant to draw natural ventilation. The performances in other periods are also presented in this paper. Linear regression models are presented in this paper can be used for predicting volume flow in the pre-design process by temperature difference for different perforated percentages.
