Thermal comfort investigation of buildings on a campus in Hunan

Investigates and analyses the thermal comfort of the campus environment, adopting both the field measurement and questionnaires. Surveys 20 classrooms and 5 dormitories and collects 1273 questionnaires. The results show that the parameters such as temperature, air velocity and clothing insulation have obvious effects on thermal comfort, and the effect of relative humidity is not evident. The operative temperature range is much wider than the comfort temperature zone in ASHRAE 55 standard, and the PMV index is not always consistent with the actual situation. Discusses the adaptability, deduces the relationship between indoor comfort temperature and outdoor mean air temperature, and compares the results with those from other field studies.
