“…The authors conducted surveys from 7:00 am to 8:00 pm. The results showed 80 % satisfaction in temperatures from 19 to 29 o C. A similar comparison was made by Krawczyk [4], but on two educational buildings -one intelligent and the other traditional. Moreover, Dębska & Krakowiak [5] analysed the thermal preferences of 83 people in three different educational buildings.…”

For many people, the feeling of thermal comfort becomes an important aspect of helping to increase concentration at work or study. Creating an appropriate indoor microclimate becomes a huge challenge for many designers of modern construction. The most important assumption of the work is to compare the thermal sensations of a group of four, aged 23 to 30, staying in the lecture class of an intelligent building and in a climatic chamber with the same internal parameters. For this purpose, the Testo 400 environmental meter was used, collecting the necessary parameters from the environment, and specially created surveys describing people's thermal feelings during the study. The air temperature and relative humidity were as follows: 21.7 °C and 30.80 %, while for the climatic chamber the same data was applied, but at the end of the study both parameters increased to 21.9 °C and 40.50 %. Moreover, it turned out that people in the lecture hall felt worse than in the climatic chamber with similar internal values. In addition, the average Thermal Sensation Vote (TSV) response showed that the perceived environment is comfortable for the study group staying in the climatic chamber, as opposed to the feeling of influenza in the room. Unfortunately, the Predicted Mean Vote (PMV) for the room and chamber exceeded the set value described in the ISO 7730 standard.

“…The research on thermal comfort in schools was carried out by Jindal [5] on 130 students. He examined the thermal environment and students' perceptions, finding that students feel best at temperatures ranging from 15.5 to 33.7 o C. The authors [6,7] dealt with research on intelligent buildings. It has to be mentioned that thermal sensations depend not only on the air temperature but also on a number of factors for example individual preferences, and heat transfer issues [8][9][10][11].…”

Abstract. The article presents the perception of thermal comfort in two buildings, intelligent and traditional. 32 people aged 18 to 22 and one women aged 52 participated in the study. Two indicators were analyzed, PMV (Predicted Mean Vote) and PPD (Predicted Percentage of Dissatisfied). The analysis consisted in comparing the actual feelings of the respondents with the results based on Fanger's model. The assessment of air humidity and thermal preferences are also shown.

“…In the literature review, a lot of research works related to TSV and PMV indicators. However, there is still almost no research (except for studies conducted by the author [3] and the other researchers from Kielce University of Technology [4,5] comparing modern construction with traditional construction. Shin et al [6] analysed the PMV and TSV for CO 2 in the university library, thus proposing a new air-conditioning solution that improves people's thermal sensations.…”

All the constantly growing thermal requirements of people pose new challenges for designers in the field of modern and smart construction. The main idea of such buildings is to ensure the best possible conditions for the internal environment, especially in public facilities. In Poland, the majority of university buildings are traditional buildings that have been modernized, thus increasing the feeling of thermal comfort by people. The aim of this article is to conduct a comparative analysis of two rooms, for the smart building "Energis" and the traditional building "B" at the Kielce University of Technology. The testo 400 device was used to carry out the study, which, through parameters taken from the environment, enabled the calculation using the ISO 7730 standard, Predicted Mean Vote (PMV) and anonymous questionnaires from which an averaged Thermal Sensation Vote (TSV). The temperature of the first room was 26.7°C, and the temperature of the second was 23.6°C. The results turned out to be intriguing as the analysis showed that the students were not satisfied with the conditions in the smart building.
