Carbon dioxide gas levels in a room can be used as an indicator of fresh air. Too many students in a classroom or too little air exchange will result in a build-up of CO2 levels over time. Fresh air contains approximately % (400 parts per million, or ppm) of CO2 molecules. In an occupied, well-ventilated room, it is not uncommon for the CO2 level to rise over 1,000 ppm. ASHRAE recommends ...

Background: We tested the hypothesis that classroom carbon dioxide (CO2 ) concentration is inversely related to child school attendance and educational attainment. Methods: Concentrations of CO2 were measured over a 3-5 day period in 60 naturally ventilated classrooms of primary school children in Scotland. Concentrations of CO2 were related to the class average annual attendance and ...
