A courtyard's thermal functionality depends on various factors, including its opening. The Uniform Building By-Law of 1984 specifies a minimum requirement of 10% openness per total floor area. Nonetheless, it is still unclear if this requirement is sufficient and effective in ensuring the comfort for indoor spaces surrounding an air well. Therefore, this study aims to investigate the effect of opening provisions on the indoor thermal environment by assessing the indoor thermal condition of an air well-type courtyard terrace house. Field measurements were conducted to measure the thermal environmental parameters of a living room and a bedroom in the selected house connected directly to the courtyard. The findings are compared and analysed according to previous literature and the ASHRAE and MS2680:2017 standards. The result indicated that the living room has a high temperature with static air movement that causes heat to be trapped inside the room. This raises the question of the current opening provision that may render a courtyard effective in moderate indoor thermal performance.
