Comparative analysis of thermal comfort in the traditional and smart buildings

Abstract

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.
