Heat waves continually intensify due to climate change, putting school children’s health and well-being at risk as they spend more time in warm environments. A field study was conducted to investigate the thermal comfort and CO2 concentration in three secondary schools in Malaysia. Field measurements in four classrooms at each school were carried out during the school day to collect environmental variables and simultaneously, questionnaires were distributed twice. 435 data sets were obtained from 232 students aged 13 to 16. The result showed that the comfort operative temperature for the school classroom was 28.7 ℃. About 78% of students reported feeling comfortable and preferred no change, with more than 90% acceptability. Most students prefer a bit warmer than much cooler conditions. Due to thicker clothing insulation, female students were found to be more sensitive to high temperatures than male students. When comparing the comfort temperature range with the ASHRAE 55 and EN15251 adaptive standards, more points lie outside the comfort band, which indicates that students of hot-humid climates are more tolerant to high temperatures. Results on indoor CO2 concentration showed that all classrooms had good indoor air quality as the average concentration was below 700 ppm, affected by occupancy and ventilation conditions. The findings can supplement existing thermal comfort standards tailored to the local climate and provide the baseline for future school design that encompasses comfort and energy savings.
