Abstract: Field measurements were carried out to evaluate the thermal comfort and energy consumption of shop-houses in Singapore residential area. Both subjective and objective measurements were obtained to analysis the general perception of thermal comfort sensation and its relations to energy consumption and efficiency of the shop-houses. Based on the data collected, the energy efficiency of the shop-houses were compared with retail buildings in Singapore. From the t-test analysis at 0.05 significant level, it was found that the mean EUI of the shop-houses were higher than the average EUI of the retail buildings. A large proportion of the energy consumed by these shop-houses was attributed to the use of HVAC systems. 47.37% of the sample population uses 41% to 60% of their energy consumption on HVAC system while 15.79% uses more than 80% of their energy on HVAC system. The general perception of thermal comfort in these shop-houses was found to be satisfactory with the sensations on the thermal, draught and humidity having more than 80% of the respondents voting between +1 and -1 on the seven-point scale. However, the general mean thermal sensation of the shop-houses was found to be slightly skewed towards a cooler sensation, which suggested for an overcooled environment, leading to energy wastage. The set-point temperature and energy labels were found to have a strong correlation with thermal comfort sensation and HVAC EUI of the shop-houses. These two variables should be considered to reduce energy while maintaining thermal comfort. The objective measurements of the thermal conditions within selected shop-houses revealed that the operative temperature were beyond the limits as recommended by the local standards. However, the higher thermal condition of the shop-house were deemed to provide a more satisfactory thermal comfort environment for its occupants when compared with the subjective results. This is in parallel with other studies which suggested for higher thermal tolerance and adaptations of the people living in the tropical climate like Singapore.
