Thermal comfort in naturally ventilated buildings in hot-humid area of China in summer: an example study of Guangzhou

Presents a 501 person-time field survey of thermal comfort in naturally ventilated buildings of an university in Guangzhou in summer 2008, during which the data of human thermal sensation, thermal comfort, thermal acceptability and humidity perception are collected and the indoor thermal parameters including dry-bulb temperature, relative humidity, black globe temperature and air velocity are recorded. The results reveal that although the thermal conditions are out of the ASHRAE comfort zone, people can adapt themselves to the local environment. Obtains the neutral temperature 28.1 ℃ (ET*=29.3 ℃) and the upper limit of the acceptable temperature 29.7 ℃(ET*=30.9 ℃) and the upper limit of the acceptable relative humidity 78%.
