In order to study the thermal environment of office prefab house in summer, the field survey investigation, including thermal parameters and questionnaire survey, was carried out in prefab houses of five building site in Guangzhou. And 749 valid questionnaires were obtained. The results showed that the indoor temperature and relative humidity are both high in most of the time, it had a strong correlation with the outdoor environment changes and the value difference is little. In addition, the upper limit of the measured acceptable temperature is 29.27 °C, the comfort temperature zone is 24.99–28.17 °C, the neutral temperature is 26.44 °C, and the preferred temperature is 25.8. Only 64% of the samples are in the range of comfort temperature, which indicates that the indoor thermal environment needs to be improved. There is obvious difference between the Predicted Mean Vote (PMV) and Mean Thermal Sensation Vote (MTSV). Therefore, the PMV model is needed to modify to improve correction for evaluation of the special thermal environment in prefab house.
