Abstract

A field study was conducted in classrooms in Malaysia which were either mechanically ventilated by fans or air-conditioned, to assess their thermal conditions during the day. Samples of occupants were asked to answer a survey on their perception of the comfort level while thermal comfort variables were measured simultaneously. Data analysis of the mechanically ventilated classrooms showed that all classrooms had thermal conditions that were higher than the comfort zone of ASHRAE Standard 55. However, the occupants found the warmer thermal conditions acceptable. Meanwhile, some of the air-conditioned classrooms had thermal conditions that were within the comfort zone of ASHRAE Standard 55. The others had thermal conditions that were outside the ASHRAE comfort zone but the occupants found the thermal conditions acceptable. Results of this study suggested a higher thermal comfort range for Malaysians compared to the thermal comfort range proposed by ASHRAE Standard 55-92 which indicated that Malaysians are acclimatised to much higher environmental temperatures. Therefore adopting the international standards for interior comfort conditions for the Malaysian hot-humid tropical climate may lead to overcooling and energy waste. The results of this study supported the current revisions to ASHRAE Standard 55 that will include a new adaptive comfort standard (ACS) that allows warmer indoor temperatures for naturally ventilated buildings in warmer climates.
