This paper researches on the thermal comfort of Lingnan Garden in summer. First of all, the method of the field measurement and questionnaire survey is used to obtain the hourly data of meteorological elements (air temperature, relative humidity, globe temperature, wind velocity) and the outdoor thermal comfort state of the Lingnan garden. Then, with the aid of RayMan model, the physiological equivalent temperature (PET) is calculated to synthetically evaluate the thermal environment state of garden spaces which are composed of different landscape elements. Finally, the regression analysis method is used to establish the correlation between human thermal sensation and thermal environment indices of the Lingnan Garden outdoor spaces and to obtain the thermal neutral temperature and the maximum temperature of PET, thus the outdoor thermal comfort evaluation model of Lingnan Garden is preliminarily established.
