In building areas with high occupancy, such as classrooms, transmission routes of SARS-CoV-2 are increased when indoor air quality is deficient. Under this scenario, universities have adopted ventilation measures to mitigate contagious environments. However, the lack of adequate equipment or designs in old educational buildings is a barrier to reach minimum requirements. This study aims to quantify the indoor air quality and thermal comfort at universities and compare it to conditions in students' households. In this regard, several classrooms in buildings of the Polytechnic University of Catalonia were monitored for temperature, CO concentration and relative humidity. The people who used these classrooms were surveyed about their comfort perceptions. A sample of students was also monitored at their homes where they reported to studying during the exam period. By means of point-in-time surveys, students reported their daily comfort, for comparison with the monitored data. The results show that the recommendations for CO concentration, temperature, and relative humidity are not always met in any of the study spaces. These factors are more critical at universities due to the high occupancy. In addition, the surveys highlighted the perception that the environment is better at home than at university.
在人员密集的建筑区域，如教室，如果室内空气质量不佳，SARS-CoV-2 的传播途径会增加。在这种情况下，各所大学已经采取了通风措施来减轻传染性环境的影响。然而，老旧教育建筑缺乏足够的设备或设计，这成为了达到最低要求的障碍。本研究旨在量化大学的室内空气质量和热舒适度，并将其与学生家庭的条件进行比较。在这方面，加泰罗尼亚理工大学的几间教室的温度、CO 浓度和相对湿度进行了监测。使用这些教室的人还对他们的舒适度感受进行了调查。还对一部分学生在家中进行了监测，这些学生报告说在考试期间在家中学习。通过即时调查，学生报告了他们每天的舒适度，以便与监测数据进行比较。结果表明，在任何学习空间中，CO 浓度、温度和相对湿度的建议都没有得到始终满足。由于人员高度密集，这些因素在大学中更加关键。此外，调查还突出了学生的这种感知，即他们认为家里的环境比学校好。
