Abstract

A buildings' glazed facades influence their inhabited occupants in terms of thermal comfort and discomfort glare. This study aims to clarify the correlation between them in a tropical context. The field study was performed in office spaces in Thailand using comfort indices evaluation, i.e. the predicted mean vote (PMV) and daylight glare probability (DGP), and questionnaire surveys to investigate local occupants' feedback. The statistical approaches indicated that the agreement between thermal comfort and discomfort glare variables could be observed with a glazing performance rating of the buildings and the occupants' sensation level. However, the usability of comfort indices must be carefully concerned with the post-occupancy evaluation since the PMV mismatched the occupants' responses with the preference of a lower level of DGP. This study is an improvement in the understanding of occupants' comfort, which allows researchers and practitioners to discuss on more comprehensive building assessment. It is necessary to study the effects of both comfort aspects separately, along with their interactions.
