Abstract

An office building in Malaysia with a green certification was examined in terms of objective and subjective evaluations of thermal comfort. In this study, thermal comfort data was collected objectively using specific instruments per the ASHRAE 55 standard, and the Predicted Mean Vote (PMV) values were computed. In addition, validated questionnaires were used to assess subjective perceptions of thermal comfort. It was found that, although the PMV model suggested a slightly cool atmosphere occupants experienced a cooler sensation than expected. The divergence highlights the inadequacies of measuring thermal comfort solely based on objective measures and stresses the necessity of incorporating occupant feedback into the assessment process. By focusing on environmental sustainability and occupant well-being, this research provides valuable insight for the management and development of future green office buildings.
