    This study was conducted on the thermal comfort of sedentary work at six air-conditioned bank offices in the hot and humid environment of Malaysia. This study aims to investigate the perceptions of thermal comfort and to determine the comfort temperature of the air for bank office employees. Air temperature, relative humidity and air velocity were measured every 5 minutes. The Predicted Mean Vote (PMV) model based on ASHRAE Standard 55 was used to estimate the requirements for indoor thermal conditions. Two types of building air conditioning systems were studied namely air conditioning and mechanical ventilation system (ACMV) and split unit air conditioning systems. In total, 124 respondents completed the questionnaire to appraise the thermal sensation vote (TSV) of the six bank offices from 8.30 am to 5.00 pm. A comparison between the PMV and TSV shows that TSV values appear to be more sensitive than PMV values. The predicted neutral temperature from PMV is lower than the neutral temperature from TSV.
