The results show that the annual thermal neutral temperature of the residents is 23.6 ℃. The acceptable temperature range of 80% respondents is 15.9 to 31.0 ℃. Increasing wind speed could significantly increase thermal neutral temperature. The thermal neutral temperature is 22.6, 23.8, 25.4 ℃ at the wind speed of 0 to 0.2 m/s, 0.2 to 0.6 m/s and more than 0.6 m/s, respectively.
