Thermal Comfort Assessment of a Classroom in Tropical Climate Conditions

摘要

Thermal comfort is the study of indoor comfort level feel by the occupant in a room. This paper presents the study of thermal comfort that had been carried out in a classroom on the second floor at a local school in Bandar Baru Bangi, Selangor, Malaysia. The study was made in 5 days from 2 pm to 6 pm. This study was carried out to assess their thermal conditions during the students' lesson hours. Thermal comfort variables were measured during lesson hours too. Objective data analysis showed that none of the classes had thermal conditions falling within the comfort zone of ASHRAE standard 55. The result shows the environmental condition of the class is warm to hot in 7-point ASHRAE scale. The linear regression between Predicted Mean Vote and Operative Temperature reveals that the maximum acceptable temperature in this field of study is 26.5℃.
