Thermal comfort in educational classrooms is essential for many reasons, including students’ work efficiency, health, and well-being. Thermal discomfort leads to ineffective studying and teaching. The research was conducted in the computer laboratory at the University of Warmia and Mazury in Olsztyn. Indoor climate parameters and outdoor temperature were registered for 5.5 months, from December 2023 to mid-May 2024. This was the heating period, but in the case of high outdoor temperatures, the room was not heated. This period allowed for collecting information on thermal comfort in winter and spring revealing the problem of overheating. Based on the recorded data, the values of the PMV and PPD indicators were determined and compared with the results of a survey conducted among the room users. Based on the measurements, survey, and observation authors presented possible scenarios for improving thermal comfort in the classroom. Different types of clothing were analyzed. Regardless of clothing thermal resistance, each scenario led to increased airspeed or decreased indoor temperature, in the case of warm clothing both actions were needed.

摘要

Thermal comfort in educational classrooms is essential for many reasons, including students’ work efficiency, health, and well-being. Thermal discomfort leads to ineffective studying and teaching. The research was conducted in the computer laboratory at the University of Warmia and Mazury in Olsztyn. Indoor climate parameters and outdoor temperature were registered for 5.5 months, from December 2023 to mid-May 2024. This was the heating period, but in the case of high outdoor temperatures, the room was not heated. This period allowed for collecting information on thermal comfort in winter and spring revealing the problem of overheating. Based on the recorded data, the values of the PMV and PPD indicators were determined and compared with the results of a survey conducted among the room users. Based on the measurements, survey, and observation authors presented possible scenarios for improving thermal comfort in the classroom. Different types of clothing were analyzed. Regardless of clothing thermal resistance, each scenario led to increased airspeed or decreased indoor temperature, in the case of warm clothing both actions were needed.
