2024 No Investigation of CO₂ production depending on physical activity of students https://doi.org/10.1080/09603123.2018.1506570 Kapalo, Peter Europe Experimental Exposure Students Carbon Dioxide (CO2) Temperature Humidity Other educational building Indoor environment carbon dioxide (CO2) production Physical activity CO₂ concentrations were measured in two university classrooms to assess how student physical activity influenced CO₂ generation. Increased physical exertion raised CO₂ levels, indicating inadequate ventilation and informing IAQ design in educational spaces. 2018
