Experimental researches on the outdoor micreoclimate of a low-rise residential building cluster

In order to analyze the characteristics of outdoor thermal environment and human thermal comfort, a field experiment was conducted in a low-rise building cluster in Shenzhen, south of China. Results of the experiment demonstrate an effective ventilation in such buildings and hence, a homogeneous air temperature distribution. However, there is large MRT difference among the districts due to solar radiation and long-wave radiation from ground surface. Consequently, intensification of ventilation, sunshade and declination of surface temperature are the major measures to enhance the outdoor thermal environment. Besides, solar radiation, long-wave radiation and the heat transfer, in the fabrics and ground should be regarded as the essential factors in the microclimate modeling.
