Abstract

This study analyses the effect of environmental factors and use of adaptive methods on the occupants’ thermal comfort in naturally ventilated educational buildings in the hot and dry climate of Vadodara. A questionnaire survey was conducted on 2674 occupants of six lecture halls of two buildings in September 2019 & January 2020 to record measures of activity, clothing level, and thermal preferences. A handheld anemometer was used to measure air temperature, relative humidity, and airspeed. It was found that the level of clothing was 0.37 to 0.69 clo in rainy and 0.52 to 1.1 clo in winter season respectively, showcasing adaptive behaviour of the occupant. The findings reveal that occupants were relatively more satisfied in January (winter season) than in September (rainy season). It is found that the thermal comfort range for RH ≥ 60%, in rainy and winter season is 27.4°C to 30.8°C (3.4°C) and is 24.1°C to 27.1°C (3°C), whereas for RH <60%, it is 27.4°C to 30.8°C (3.4°C) and 24.1°C to 27.1°C (3°C) respectively. It also establishes that the occupants preferred a slightly cooler temperature in the rainy season but preferred a slightly warmer temperature in the winter season.
