The comparison of thermal comfort test results in selected traditional and modern buildings

Abstract

The use of renewable energy sources in buildings is more and more common (both for heating and cooling purposes, as well as electricity generation). The paper focuses on the thermal comfort tests in two buildings: the traditional one (that uses non-renewable sources of energy) and the modern intelligent building “Energis” of Kielce University of Technology. The thermal sensations of students in these two buildings have been compared based on the questionnaire survey and conclusions have been drawn regarding the differences between the feelings of thermal comfort in those two buildings. Apart from subjective feelings of the volunteers, the measurements of indoor air parameters were conducted in both buildings and have been presented in the paper.

Analysis of indoor environment perceptions in the smart building

“…Only one room was too cold for the respondents, therefore they want the temperature in the room to be warmer. Comparing with the results from [3], the respondents preferred warmer thermal conditions. The respondents were also asked about the assessment of air humidity (Fig.…”

“…International standards ([1], [2]) on thermal comfort determination were developed after the foundations laid by a pioneer in this field, namely O. Fanger originating from the 1960's. Recent studies [3] on thermal comfort in a smart building have shown that there is a difference between subjective feelings and actual results. Similar conclusions were observed in the authors [4,5].…”

Traditional and Intelligent Buildings – Perceptions of Thermal Comfort

“…However, for the second building, research was carried out in January 2022. Air temperature, relative air humidity and air velocity for the traditional building are 27.7 o C, 47.60% and 0.05 m/s [3], while for the intelligent one: 25.1 o C, 29.72% and 0.09 m/s.…”

“…In this study, a study was carried out for two buildings, a school building and an intelligent building of Energis of the Kielce University of Technology. The results for the first building were taken from the article [3]. However, for the second building, research was carried out in January 2022.…”

“…Currently, many researchers are involved in research on thermal comfort in school buildings, homes, universities, and offices, and less in intelligent buildings. The research on thermal comfort in intelligent buildings was carried out by Krawczyk and Krakowiak [3], who compared the results of an intelligent building with a traditional building. The research shows a difference between the PMV index and the actual results from the questionnaires.…”
