Evaluating and comparing objective and subjective thermal comfort in a malaysian green office building: A case study

Abstract

This study examined thermal comfort in a sustainable office building in Malaysia, with the goal of understanding how objective environmental data relates to occupants' subjective experiences. The study utilized established thermal comfort models, such as the predicted mean vote (PMV), in conjunction with occupant surveys to evaluate the indoor environment. Objective data aligned with thermal comfort criteria, but subjective thermal sensation vote (TSV) showed a notable difference. The environment felt colder than anticipated by the occupants. This study emphasises the drawbacks of depending exclusively on conventional thermal comfort models, especially in tropical settings. The research emphasises the importance of considering individual variability (physiological and psychological), localised environmental variables, and potential adaptive comfort mechanisms impacted by regional climate. This research aims to develop a thorough understanding of green buildings' inside climates to inform design methods for achieving optimal thermal comfort, energy efficiency, and reduced carbon emissions. The results provide guidance on methods for emphasising occupant-centered design in sustainable buildings located in tropical areas. This study focuses on filling the knowledge gaps regarding the dynamics of thermal comfort in green buildings located in tropical regions. Combining empirical data with subjective feedback emphasises the need for design strategies that focus on occupant well-being in addition to energy efficiency goals.
