| Abstract | Thermal comfort study is very important because it correlates occupants comfort in built environment to the functioning of the building and energy consumption. PMV-PPD method works fairly well for conditioned buildings. However, this method does not provide expected results when applied to naturally ventilated buildings. Naturally ventilated buildings are much more dynamic compared to conditioned buildings in terms of thermal environment and occupant’s behaviour in the built environment. In this study, questionnaire based thermal comfort survey has been carried out in naturally ventilated classrooms of Tezpur University during the months of February and May 2013 i.e. at the end of the winter season and the beginning of summer. Thermal sensation and preferences of 228 students are recorded on ASHRAE thermal sensation scale. Various associated parameters like indoor and outdoor air temperature, humidity, clothing and metabolic rate are also measured. The results reveal that the subjects did not feel extreme levels of thermal discomfort during this period. It has been observed that there is a large variation in the clothing pattern (0.83 to 1.52 clo in winter and 0.43 to 0.68 clo in summer) in both the seasons which justify the behavioural, physiological and psychological adaptation of the respondent. It is also found that the other adaptive means like use of fans, closing or openings of windows etc are used quite often. This study concludes that the comfort temperature range varies from 22 to 23.5 °C in winter month and 27.3 to 30.7 °C in summer month. It also concludes that most of the objects recorded cool thermal sensation and preferred a warmer climate in winter and warm thermal sensation and preferred a cooler environment in summer. |
