This paper investigates student’s thermal comfort in the intelligent building called “Energis” of Kielce University of Technology located in Poland, which is equipped with advanced heating, ventilation and air conditioning (HVAC) mechanical systems. One lecture theater is selected for thermal analysis. Analysis was focused on student’s assessment of thermal sensations in the autumn season to determine whether modern intelligent buildings can provide adequate comfort conditions during the European transitional period, which is between summer and winter seasons, when heating system is usually off. This study is based on survey data and experimental measurements of indoor parameters using a microclimate Testo 400 meter. The experimental data indicate that a relatively large proportion of students are not satisfied with indoor environmental air quality prevailing in the intelligent building. The results of this study indicate that only 10% of students reported weak productivity related to indoor environmental conditions in the building. In addition, 52% of students describe their thermal sensations as comfortable and 17% of students are not satisfied with environmental conditions in the lecture room. Therefore, improvements on existing mechanical systems for indoor air quality is recommended. Furthermore, it is recommended to conduct more experimental trials and surveys to confirm the results presented in this paper in different University buildings.

现代阶梯教室的热舒适度评估：波兰凯尔采科技大学 - 案例研究

本文调查了位于波兰凯尔采理工大学名为“Energis”的智能建筑中学生的热舒适度，该建筑配备了先进的供暖、通风和空调（HVAC）机械系统。选择一间报告厅进行热分析。分析的重点是学生对秋季热感觉的评估，以确定现代智能建筑是否能够在欧洲过渡时期（夏季和冬季之间，供暖系统通常关闭）提供足够的舒适条件。本研究基于使用小气候 Testo 400 仪表进行的调查数据和室内参数的实验测量。实验数据表明，较大比例的学生对智能楼宇中普遍存在的室内环境空气质量不满意。这项研究的结果表明，只有 10% 的学生表示生产力低下与建筑物的室内环境条件有关。此外，52%的学生表示他们的热感觉很舒适，17%的学生对教室的环境条件不满意。因此，建议对现有的室内空气质量机械系统进行改进。此外，建议在不同的大学建筑中进行更多的实验和调查，以证实本文提出的结果。
