This paper presents the findings of a short-term monitoring exercise and questionnaire survey to assess the thermal comfort conditions actually being achieved in 6 Iranian Office buildings. The findings of the questionnaire and monitoring are compared to give confidence that the questionnaire is accurately reflecting the calculated comfort conditions obtained from the physically monitoring and site observations. The perceived thermal comfort conditions for the buildings are then compared with current thermal comfort standards to ascertain whether there is potential for improvement. The results from this study indicate that there is a good agreement between the monitoring and the questionnaire for the majority of the offices. The results also show that there appears to be room for significant improvement in thermal comfort conditions in a number of the Case Studies. These findings will be used as part of further work to explore how we might improve the thermal conditions through improvements to the Offices fabric design.
