THERMAL COMFORT OF NATURALLY VENTILATED BUILDINGS IN HOT SUMMER/COLD WINTER REGION, CHINA
A thermal comfort field study has been conducted in five cities in the hot summer/cold winter region in china. The survey was performed in naturally ventilated buildings during the summer season in 2006. A total number of 129 occupants from 65 buildings took part in this study. Thermal comfort variables were measured at the same time when occupants answered a questionnaire concerning their thermal perception of the indoor climate. The neutral operative temperature was found to occur at 28.3 ℃ and the range of accepted temperature was between 25.0 ℃ and 31.6 ℃. Thermal acceptability assessment reveals that indoor environment couldnt meet the 80% acceptability criteria prescribed by ASHRAE Standard 55. Thermal preference analysis reveals that people had a preference to cooler conditions than neutral. Indoor air velocity had a significant influence over the occupants comfort sensation and people required a high level of air velocity in order to feel comfortable in summer. The study also investigated the occupants adaptive control preference in creating a more thermally comfortable indoor environment.
