The aim of the study is to investigate the desired ASHRAE thermal sensation versus the ASHRAE sensation scale in the humid tropics of Malaysia. This study was carried out in university classrooms by means of both objective and subjective approaches. The field study was conducted in the Faculty of Engineering, University Malaysia Sabah. This study discussed some of the issues in using different scales for predicting comfort temperature and the preferred temperature. The results showed that the desired thermal sensation was lower than the neutral sensation by about one unit.
