Abstract: The Star Vista is an iconic commercial development that distinctively differentiates itself by using natural ventilation as a means for cooling for most of its semi-outdoor spaces. With numerous airflow simulations done prior to its construction to maximize the natural ventilation effect, it was no surprise that it was awarded the BCA Gold Mark rating. It also reported impressive results in terms of energy savings due to the reduced reliance on air-conditioning and mechanical ventilation systems. However, with Singapore’s tropical climate and increasing susceptibility to the haze, this design of The Star Vista questions its effectiveness in providing thermal comfort to its occupants. Hence, the emphasis of this study was on the thermal comfort performance and the corresponding occupants’ thermal sensations/perceptions of selected semi-outdoor spaces. Objective measurements dictated that majority of the spaces fell below ASHRAE’s standards of thermal comfort, where these spaces were warmer than what it was supposed to be. On the other hand, results from the subjective assessment derived varied responses of perceived thermal sensations and comfort. One distinctive outcome showed that while occupants indicated sensations of warmth, it did not necessarily translate to discomfort. After all, occupants in the tropics are more likely to be acclimatised to and accepting of the warm thermal conditions. Therefore, standards may not accurately conclude the thermal comfort performance of these naturally ventilated spaces. Other factors have to be considered such as the adaptive approach by humans and the onset of unpredictable outdoor conditions. The relevant recommendations will be made with respect to the varying types of activities and functions of the selected semi-outdoor spaces in study. As a more tangible guide to attain thermal comfort, Feriadi’s comfort chart was used to match the necessary air temperature to be achieved in spaces that fell out of the chart’s recommendations.
