The paper presents experimental results of a study on indoor thermal environment in selected educational buildings located in the city of Kielce (Poland). The volunteers in the investigated rooms were asked to fill in the anonymous questionnaires containing questions on their thermal sensation, thermal preference and thermal acceptability votes as well as humidity assessment and humidity preference votes. In total, 83 people completed the questionnaires. Simultaneously, the indoor air parameters were measured with a microlimate meter equipped with precision sensors to measure air and globe temperatures, air velocity and relative humidity. The analysis of the obtained results provides information on the subjective assessment of the thermal environment in the considered rooms. It allowed to assess whether the guidelines given in the standard are consistent with the real feeling of comfort of the respondents. Research in the performed scope has shown that the feelings of the respondents and the standard guidelines diverge. It was noticed that that the subjects definitely felt better in the rooms where the temperature was around 22.5°C. The subjects felt worse at the temperature of 25.3°C and the worst of 27.6°C.
