Thermal Environment Dynamic Simulation of Double Skin Façade with Middle Shading Device in Summer

Double-skin facade (DSF) can be thermal insulation either in summer or winter. While building shading devices can reduce the solar radiation heat gain through windows effectively, save building energy consumption and improve indoor thermal environment quality in summer. Based on the dynamic simulation of the indoor environment, this paper puts the blinds inside the intermediate cavity, simulates the effect of different locations and inclinations, analysis their influence on ventilation effect, intermediate cavity temperature and indoor temperature. And finally, a relatively optimal design and utility plan is summarized to provide some references for middle shading device design and evaluation of this field.
