jailcd2019-105： Ventilation Type Modification to Achieve Thermal Comfort

Abstract

This paper analyzes the indoor and outdoor thermal comfort of the classroom FPIPS (Faculty of Science and  Social  Education),  Indonesian  University of Education. This  study  aims to  determine  the  effect  of ventilation on indoor and outdoor thermal comfort in classrooms. The measurement is taken at 07.00 am (morning), 11.00 pm (afternoon), and 16.00 pm (evening) by using the Wind and Weather Meter to find out Temperature (˚C), Humidity (%), and wind speed (m/s). The data then calibrated with Rayman 1.2 to find out PET (Physiologically Equivalent Temperature) in the hot and humid climate context. The results show that the indoor and outdoor of the classroom have PET in the same range, which is slightly warm. However, in this case, the temperature in the indoor is higher than the temperature in the outdoors. It is known based on the calibration results with Ray-man that the PET of outdoor is at 31.9  ˚C while the indoor has a higher number is at 32.3 ˚C. The study result shows that vent has an important role in channeling wind in a building and influence to reduce PET index. The design recommendation will be given to improving the thermal comfort in the classroom
