THERMAL COMFORT OF A COURTYARD IN GUANGZHOU IN SUMMER

摘要

The quality of outdoor thermal environment directly influences the indoor air quality. The improvement of the quality of the outdoor ambience is a positive way not only to improve the indoor air's quality but also to prevent the vicious cycle of deterioration of the environment-energy consuming increasing- deterioration of the Environment. In this paper, a survey of the thermal comfort in an outdoor courtyard in Guangzhou city was recorded. Eight hundred sixty-eight pupils were questioned about their comfort level in this outdoor space while the climate factors were recorded. Basic physical factors (solar radiation, air temperature, wind speed and relative humidity) influencing the outdoor environment were analyzed by regression analysis. The design reference of outdoor environment was provided correspondingly. The relationship between thermal comfort and thermal stress index, WBGT, was discussed extendedly.
