Previous studies on thermal comfort have been mainly conducted in climate chamber, summer and winter in air-conditioned buildings and summer in naturally ventilated buildings, but rarely in transition season (non-air conditioned environment) in air-conditioned buildings. For buildings with large space and high density of people like in high-speed rail station, the thermal comfort of passengers in waiting room in non-air conditioned condition should be a concern. According to ISO 7730 and ASHRAE 55, field studies have been carried out in two high-speed railway stations during late spring and late fall in Shandong and Hebei, two provinces located in the cold region of China, using a subjective questionnaire survey simultaneously with thermal environmental parameter monitoring. As a result, the neutral temperature of the passenger was revealed, and the thermal acceptability and preference are discussed. In addition, a suitable model to predict the thermal comfort of the passenger in transition season was developed. Ultimately, we studied the relationship between the length of the waiting time and the thermal comfort of the passengers.
