Thermal comfort investigation of naturally ventilated classrooms in a subtropical region

That study was performed in the Chinese Hunan University. During one month, thermal comfort was measured in 25 naturally ventilated classrooms equipped with ceiling fans. 1273 students responded to a questionnaire on their perception/sensation of the indoor climate. Most of them found thermal satisfaction though indoor air temperature and relative humidity varied a lot. The results are different from that found in other similar thermal comfort studies, it is attributed to the different climate and to the adaptation and tolerance of students too.
