Abstract:In the modern world, a person spends most of his life indoors. That is why it is so important to create optimal conditions for the internal environment. Research on thermal comfort and subjective feeling of people inside the building can help in this. The article discusses two methods that are used in research on thermal sensations. This makes it possible to know the thermal assessment of people and then compare this result with the calculated PMV value, which is calculated using the formula from ISO 7730 stan… Show more

“…Finally, the TPV, TAV, and TCV indices are used in numerous investigations and are included in some of the thermal comfort evaluation surveys, especially in those carried out by university students because they can respond more accurately to the nuances of these questions [159,164,175,186,191,216,238,253,257]. The same is true for HSV and HPV where the effect of humidity is analysed independently [187,210,212,215,229,235,247].…”
Thermal comfort in educational buildings affects not only the well-being of students but also their academic performance. Over time, various methods have been developed to assess it. However, none of them takes into account the adaptation of students of different ages, which is an important issue. In recent years, the study of thermal comfort has become very important due to energy-saving measures and ventilation protocols to combat the spread of the SARS-CoV-2 coronavirus. Therefore, it is necessary to gather all the information to guide future research. Thus, this paper presents a comprehensive review of field studies on thermal comfort in classrooms at different educational levels. The focus is on those conducted during the global pandemic of COVID-19. It has been observed that students from climates with a higher degree of variation have shown a better adaptation. Children also tended to feel less affected by changing temperatures. High school and university students showed a greater range of dissatisfaction with heat than with cold. The adaptive approach is more suitable for recognising the comfort needs of all age groups. However, by using this approach together with the Fanger method, more reliable results have been reported. In most of the studies, comfort levels were found to be lower than those indicated by the standards, highlighting the need for guidelines adapted to the thermal comfort conditions of all students. Finally, the various natural ventilation measures to avoid COVID-19 infection have led to a decrease in comfort levels, especially in winter.

“…Currently, many researchers conduct research on thermal sensations in many public buildings, such as schools, colleges, offices, hospitals, homes, dormitories and, to a lesser extent, intelligent buildings, in various climatic zones. The first such examples is a study carried out by Dębska & Krakowiak [3,4], where measurements of the internal environment with differentiated ventilation, such as using the BMS system control, were carried out in three rooms, the parameters could not be changed into other ones and with the use of air exchange through gravitational ventilation. A total of 83 people were examined.…”
The proper design of buildings should ensure that the indoor conditions are comfortable, and users experience thermal comfort throughout the year, especially in sophisticated, modern intelligent buildings. The existing model of thermal comfort comes from the 60’s/70’s and was the basis for the ISO 7730 Standard. It utilizes the concept of the PMV (Predicted Mean Vote) and PPD (Predicted Percentage Dissatisfied) indicators. The current paper compares the actual expressions of people (as indicated by them in the anonymous questionnaires) with the PMV/PPD values calculated according to the Standard. Differences between these values have been discussed and conclusions have been drawn as to the usability of this thermal comfort model in intelligent buildings, which still seem to be a novelty in Central European countries and data on their thermal comfort performance is still quite modest.
