EXPERIMENTAL STUDY ON OUTDOOR THERMAL ENVIRONMENT OF CAMPUS BUILDING CLUSTERS IN TROPICAL CLIMATE

A 33-hour field measurement was conducted in two typical campus building clusters located in Guangzhou, China. Thirty measuring points were set and local climate data, air temperature, relative humidity, wind velocity, wind direction, WBGT at the pedestrian-level, ground surface temperature and etc. were measured. The experiment results show the typical property of thermal climate in the hot and humid area of China. The tree-shading, piloti and patio are found to be helpful for outdoor thermal comfort and recommended to be adopted in tropical climate. Compared with the teaching building cluster, the residential building cluster has 0.6 � lower pedestrian-level air temperature, 2.4 % higher relative humidity, 0.05m/s lower wind velocity and 0.5 � lower Wet Bulb Globe Temperature (WBGT).
