建筑设计的最大挑战是优化自然能源的使用，以提供人类舒适度并消耗更少的能源。被动立面技术的开发越来越复杂，以实现舒适性和可持续性方面。本研究旨在探讨双层幕墙与多孔幕墙整合之幕墙系统之性能。本研究的目的是利用建筑物的双层皮穿孔立面与空气通风口，以优化节能，这也是改善日本的日光和自然通风。本研究系以建筑物模拟软体分析建筑物之性能。利用DIVA软件进行模拟计算，得到了系统的日光性能。利用Design Builder软件对自然通风和能耗进行了模拟。获得日光而不眩光的穿孔屏幕是具有40%穿孔百分比的屏幕。本研究发现，当日本各地的天气都适合自然通风时，50%的穿孔率是平衡自然通风和春季日光的最佳比率。本文还介绍了其它时期的业绩。本文提出的线性回归模型，可用于预测不同开孔率下，在预设计过程中的温差体积流量。
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.
