Thermal comfort sensation is different among people. Different climatic areas, such as the tropics and cold regions, may require different thermal parameters. This study analyses the thermal sensation of occupants in domestic buildings in three regions of China (Jinan, Xining, and Guangzhou). Filed measurements were conducted in selected domestic buildings located in Jinan, Xining and Guangzhou. The studied parameters include ambient air temperature, indoor air temperature, indoor radiation temperature, airflow velocity, predicted mean vote (PMV) and actual mean vote (AMV). In addition, a survey to investigate the actual comfort levels of occupants was completed by the occupants. The main aim is to identify the differences in thermal sensation of occupants living in different regions and in different types of buildings. Moreover, this study further analyses the effects of the ambient environment on indoor thermal comfort. The correlation between the actual thermal sensation and the predicted thermal sensation is discussed. Results show that the ambient environment has a greater effect on the thermal comfort level of naturally ventilated houses than those ventilated by air conditioners. Moreover, Fanger’s predicted mean vote (PMV) model is good at predicting the thermal sensation of occupants living in air-conditioned houses; however, the model is not a good predictor for occupants living in naturally ventilated houses. Occupants in naturally ventilated houses have a wider range of thermal acceptance than those living in air-conditioned houses.
