THERMAL COMFORT IN UNIVERSITY BUILDINGS – DIFFERENCES BETWEEN MEASURED VALUES AND OCCUPANTS’ SUBJECTIVE EVALUATION

Abstract

The number of research results regarding thermal comfort worldwide has been significantly increased in the recent period, while the results in this scientific field for Serbia are limited. The question of thermal comfort and indoor environ-mental quality in naturally ventilated educational buildings is especially important having in mind the impact on occupants who spend the most of their time indoors. Additionally, it is important to emphasize the impact of thermal comfort and indoor environmental quality on occupants’ working performances. The results of the rese-arch that was performed during the winter semester in a university classroom in Belgrade showed the significant quantitative deviation between the PMV index values obtained by measurements and the values gathered through the occupants’ survey. Comparing the results over a four week period, it has been concluded that the most favorable thermal conditions and also the most unfavorable ones were confirmed by both measurements and the survey results, but with the different PMV values.
