Impact of air guide design of residential balcony on indoor ventilation in Southern Taiwan

Aiming at the hot and humid climatic conditions in southern Taiwan, this study discusses the terminologies of buildings, namely the impact of balcony on natural ventilation and indoor temperature, and probes into two vertical air guide designs (general and ventilated) of balcony, as well as reviews the impact of balcony depth. The research methods include field measurement and numerical simulation. The findings show that the air guide balcony of this study can be adopted for small depth, and the balcony with vertical air deflector design is recommended for large depth, not only increasing indoor air velocity, but also improving the warming phenomenon resulted from the increase of balcony depth.
