Europe Observational Exposure Ventilation rates Temperature Humidity Carbon Dioxide (CO2) Ventilation Thermal comfort carbon dioxide (CO₂) Ventilation rate Indoor air quality During winter exams in higher education centers, natural ventilation kept CO₂ levels well below IDA 2 limits, reducing COVID-19 risk. However, low outdoor temperatures led to discomfort. Findings support climate-based ventilation strategies. 2022
