Abstract: There are comprehensive studies performed on the field of thermal comfort (TC), however there are limited studies conducted on the thermal comfort of naturally ventilated hospital wards, especially in Singapore. While the Green Mark Scheme actively encourages naturally ventilation concepts to be integrated into building designs, little is known about the post-occupancy thermal comfort performance. This study involves 369 hospital staff to determine if they are satisfied with the thermal conditions, before and after retrofitting works were conducted in a hospital with naturally ventilated hospital wards. Field survey and measurement were conducted to record occupants’ thermal perceptions and preferences. Inter-correlation analysis between the results and nature of the questions revealed that, more occupants were satisfied after the retrofit. They were also found to vote differently on the Bedford scale than the American Society of Heating, Refrigerating and Air Conditioning Engineers (ASHRAE) Scale, which is synonymous with findings of previous TC works in the tropics. Multiple linear regression was applied to establish the independent variables to predict neutral temperature (Tn). Results showed that most of the variables were statistically insignificant. Then, recorded ASHRAE votes were plotted against operative temperatures, as a secondary method to predict and validate Tn. The predicted Tn deviated significantly from previous studies. The plausible reasons for the aforesaid results were explored and discussed. Future studies were also suggested, which could provide a more detailed analysis of TC, by predominantly expanding the sample size and evaluating the impacts of the design on thermal conditions.
