Résumé

Field study was conducted during summer in composite climate of Jaipur, India. The purpose of carrying out this study was to evaluate thermal adaptation in six naturally ventilated hostels. Total 429 survey samples of undergraduate students were collected whose average age was found to be 19.6 year. Analysis of occupants' responses and recorded thermal environmental variables show that students felt thermally comfortable at higher temperatures. Thermally neutral or comfortable temperature was found 30.15°C (comfortable temperature bandwidth, 25.9°C to 33.8°C) and average clothing insulation observed was 0.41 Clo (minimum 0.23 Clo and maximum 0.82 Clo). Ambient temperature was found between 27 to 36°C. Desirable air velocity and relative humidity was obtained such as 0.51m/s and 40%, respectively. About 40% students felt thermally comfortable at existing room conditions. Students had personal controls such as opening of window and door, change fan speed, change in clothing and activity etc. Study also described the effect of these measures to restore thermal comfort state. Results predict that neutral temperature was 2 to 3.2°C higher compared to the thermal comfort standard and models. The difference is due to the samples being collected from one particular age group, activity and lifestyle of the occupants.
