Abstract: Eating out at hawker centres can be seen as the epitome of Singaporean’s approach to lifestyle. However these food complexes do not usually provide a healthy environment for dining as poor air circulation was commonly reported by occupants. This serves as a considerable rationale to critically determine the thermal comfort conditions of the hawker centre so as to meet the satisfaction of the patrons. The field study was conducted at Lau Pa Sat Festival Market. Objective measurements dictate an overwhelming response of dissatisfaction with the thermal environment as the environmental profile of the sampling locations fell out of the recommended comfort zone to the warm – hot category of comfort, according to international standards. Subjective assessments derived varied responses of acceptability. More occupants felt that the environment was satisfactory even though they voted beyond the acceptability range. As such, the assumed evaluation of acceptability must be given contemplation to. It also implies that the standards may not be representative of thermal comfort in a naturally ventilated environment; which may be attributed to the unpredictable outdoor conditions and the adaptive approach undertaken by humans. The presence of ceiling fans in the distinctive high ceiling in Lau Pa Sat cause warm air to move in the direction of the occupants seating area during its circulation; hence the desired thermal sensation was not yielded. It is recommended that horizontal ductless tube fans be incorporated to move air across horizontally, and to promote ventilation within the food centre; established through a CFD simulation approach
