Implementation of a multi-phase approach for investigating and remedying a thermal comfort problem in an office building

This study presents the implementation of a multi-phase investigation and remedial approach aimed at solving a thermal comfort problem in an office building which was the subject of complaint. As part of the first phase to verify existence and extent of the problem, a simple and practical questionnaire survey was developed and utilized to try eliciting the occupants' perception of the thermal comfort quality of the space in question. Additionally, field measurements of space thermal parameters and the Heating, Ventilating and Air-Conditioning (HVAC) system parameters were conducted as part of the preliminary and detailed assessment stages. Analysis of assessment results has lead to the identification of short-term and long-term remedial measures to alleviate thermal comfort problems and improve the quality of thermal comfort in the office space.
