IMPACT OF VERTICAL WIND DEFLECTORS INSTALLED AT PARAPET OF RESIDENTIAL BALCONY ON INDOOR AIR FLOW AND TEMPERATURE

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 wind deflector systems (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 balcony with vertical wind deflector system (ventilated type) of this study is better than the other (general type), and it can be adopted especially for small depth. Moreover, both types of the balconies with vertical wind deflector systems are also recommended for large depth, not only increasing indoor air velocity, but also improving the warming phenomenon resulted from the increase of balcony depth.
