The paper analyses thermal comfort in an intelligent building. Intelligent buildings are now widely seen both in Poland and abroad as a result of developments in engineering sciences. However, data on the thermal comfort provided in the buildings are limited. The research described in this paper was carried out in ENERGIS intelligent building of the Kielce University of Technology. The parameters measured included air temperature, relative air humidity, air flow rate and carbon dioxide concentration. Average radiation temperature was determined. The key element was the study of thermal sensation in occupants present at the time of the measurements. The studies were performed in classrooms during the class. The students completed a questionnaire at the beginning and end of the class. The persons present in the classrooms evaluated their thermal sensations using a seven-level thermal comfort scale. The questionnaire included such questions as the type of clothing and the degree of physical activity of the people sitting in the classroom. On the basis of the measurements of classroom microclimate parameters, PMV (Predicted Mean Vote) and PPD (Predicted Percentage Dissatisfied) indices were determined. The responses from the questionnaires provided actual average assessment of thermal sensation and actual percentage of dissatisfied people.
