The paper discusses the issue of thermal comfort expressed by the students of the University of Žilina in anonymous questionnaires. The volunteers rated their thermal sensations, preferences as well as lighting conditions in the autumn season. The students were in favour of the prevailing thermal conditions - almost 88% of the volunteers expressed positive opinions about their environment. The comparison of the test results for a computer laboratory with the Fanger model calculation results was also made and indicated differences between the experimental data and values determined with the model.

W artykule omówiono zagadnienie komfortu cieplnego studentów Uniwersytetu w Żylinie w oparciu o anonimowe ankiety. Ochotnicy oceniali swoje odczucia termiczne, preferencje oraz warunki oświetleniowe w okresie jesiennym. Studenci wyrazili się pozytywnie w zakresie panujących warunków termicznych - blisko 88% odpowiedzi. W pracy dokonano również porównania wyników badań w laboratorium komputerowym z wynikami obliczeń wg modelu Fangera i wykazano różnice między danymi eksperymentalnymi a wartościami wyznaczonymi modelem.

Today, more and more buildings are being built based on the idea of sustainable development. This mainly concerns the creation of such microclimate conditions in the rooms that a person feels comfortable inside. Therefore, the article presents tests of thermal comfort for three teaching rooms in an intelligent building. The research was carried out using two methods, a microclimate meter measurements and questionnaires. The survey provided research results on thermal sensation vote, thermal preference vote and humidity assessment. Moreover, the results of Predicted Percentage of Dissatisfied and Predicted Mean Vote were presented in the paper. Students between the age of 21 and 25 and one female in her 30s participated in the survey. Through the results of the questionnaires and the microclimate meter, significant differences were shown between the Fanger model and the questionnaires in terms of PMV and PPD.
