Abstract: A large-scale field survey to measure indoor environmental parameters such as air temperature,air velocity and relative humidity was conducted in Chongqing,P. R. China,a city in a hot summer and cold winter zone. Subjective questionnaires and the ASHRAE seven-point thermal sensation scale were used to evaluate thermal,humidity and velocity sensations. Probability methods were employed to calculate the preferred temperatures. The results show that the preferred temperatures are 25.1 ℃ in summer and 21.1 ℃ in winter,respectively. Based on a comparison of the difference between neutral and preferred temperatures,it is proposed that human temperature sensitivity influences preferred temperature.
