【 摘 要 】

Piloti is commonly used to optimize the outdoor thermal environment in subtropical climate cities, and there are few studies regarding to the systematic influence of piloti on outdoor thermal comfort. As the outdoor thermal comfort differed by various climates and locations, this work firstly carried out a questionnaire survey in Guangzhou, China, to study on the local acceptance rate (TSV is lower than 1.5) during different SET∗ intervals. Secondly, a series of cases were simulated by coupled simulation method, which considering convection, radiation and conduction, offering high precision prediction results. At last, by adopting SET∗ as standard index, taking both of the questionnaire survey result and ASHRAE standard into consideration, the influence of piloti on residential block's outdoor thermal comfort was analysed and discussed.
