This study presents the findings of the significance between thermal comfort and air movement perception, acceptability and satisfaction in Singapore context. Correlation between these environmental factors together with individual's perceived job performance was also analyzed. In addition, temperature distribution across the office was also discussed together with occupants' satisfaction with regards to their thermal comfort level. Data was collected through environmental measurement equipment and thermal comfort paper-based survey questionnaires. The hypothesis made in this study was that human thermal comfort level would be affected by temperature and perceived air movement. Information obtained from the surveys was compared with the real-time data recorded by the instruments and determine the possible reasons that affected their satisfaction and acceptance towards the thermal environment. The results showed that the air temperature and air movement were statistically significant and there was correlation between the satisfaction with environmental factors and job performance. As different responses were collected from the questionnaires, individual's thermal satisfaction was plotted against the office layout to determine the zones that had received the most dissatisfaction. The study also suggested locating individuals who were sensitive to temperature changes according to the temperature distribution in the office.
