This study evaluates the indoor thermal performance in an office space due to the effects of wall materials and night cooling strategies. The combined research methods of this study involved firstly the field measurement and monitoring work on the existing office space at the Development and Property Management Office, Universiti Tun Hussein Onn Malaysia (UTHM). It was to acquire the actual indoor data and provide data for verification of Ecotect simulation program. Secondly, the modelling and simulating of the existing office building in Ecotect so as to evaluate the indoor operative temperature and indoor comfort condition of the office space. The final stage was conducting the parametric study to investigate indoor thermal condition in response to the passive cooling strategies (i.e. changing wall material and night cooling). The study showed that the verification of simulated and measured results indicates a good agreement with discrepancy value less than 10% and can be considered acceptable as suggested by many researchers. It was also found that by changing to high thermal mass wall material could improve building’s thermal performance index and reduced peak indoor operative temperature about 1°C. Indoor comfort condition in the office space during the office hours was improved about 22% (on the ground floor) and 30% (on the first floor). The results also demonstrated that night cooling compensate the drawback of high thermal mass material and reduced the indoor operative temperature in the early hour of office hours. High thermal mass wall material offers a high potential alternative wall material construction in providing better indoor environmental condition during the day particularly in office building.
