Investigating adaptive thermal comfort in office settings: A case study in Johor Bahru, Malaysia

Abstract

This study investigates the notion of adaptive thermal comfort in office settings situated in the tropical climate of Johor Bahru, Malaysia. The primary objective of this study is to examine the impact of regulated office attire and different types of spaces equipped with varying ventilation systems on individuals' perception and adjustment to thermal comfort. Data was collected through various research methods, including quantitative and qualitative techniques, as well as surveys, observations, and tangible measurements. The study's results highlight the significance of clothing insulation in achieving optimal thermal comfort. Individuals who could adjust the insulation of their clothing within a range that was deemed comfortable expressed greater satisfaction. Additionally, it has been found that semi-outdoor environments featuring natural ventilation provide a wider range of comfortable temperatures compared to indoor spaces equipped with air conditioning. This suggests the possibility of designing public areas prioritizing natural ventilation to enhance comfort and promote sustainability. Furthermore, this study delineates potential avenues for future research within the context of Malaysia and the climatic conditions prevalent in tropical regions. It is worth noting that there is a recommendation to research the influence of air velocity on thermo perception and adaptation, as previous studies have indicated its significant effect on the perception of comfort. Furthermore, it is crucial to prioritize calculations and simulations of energy consumption to assess the potential for energy savings through adaptive thermal comfort strategies in the specific local context. This will aid in the advancement of sustainable and energy-efficient design strategies. The findings above enhance the understanding of adaptive thermal comfort in Malaysia and offer valuable insights for optimizing workspace design and management. Enhancing productivity, well-being, and energy efficiency in office buildings can be achieved by addressing the thermal comfort requirements of office workers. The findings and recommendations of this study have the potential to provide valuable assistance to policymakers, architects, and facility managers in the establishment of office environments that are healthier, more comfortable, and more energy-efficient within the context of Malaysia's tropical climate.
