Abstract
Building shading and natural ventilation are the two of traditional and efficient energy-saving technologies at hot summer and warm winter zone. However, building exterior shading may block or guide the air inlet or outlet, which would result in positive or negative effects on natural ventilation. For optimizing the building shading and natural ventilation and to make them better combination, this paper selected a high-rise building in Guangzhou as the research object, then used STAR-CCM+ software to simulate the building indoor ventilation, analyze the indoor ventilation situation, and trend under shading conditions or not, through which the vertical movable exterior sunshade devices’ impact on indoor natural ventilation was revealed. At last, this paper summarized the vertical movable exterior sunshade devices’ impact on indoor natural ventilation in Guangzhou area.
