Classroom carbon dioxide concentration, school attendance ...

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 35 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 ...

CO2 Control In School Classrooms AirTest Technologies

CO2 Sensors will automatically regulate fresh air delivery so that overventilation does not occur. In fact if fresh air is being delivered from another location such as an open window, hallway or another unoccupied classroom, the sensors will react to this source of fresh air and adjust the ventilation rate accordingly. CO 2 control is also an ideal way to control ventilation based on ...
