Sick Classrooms Caused by Rising CO2 Levels

· The accepted standard CO2 level in a classroom is 1000. That level is easy to maintain when a classroom is empty. Fill the classroom up with a bunch of students and the level of CO2 rises dramatically. That’s because carbon dioxide makes up a part of every breath you exhale causing the levels to rise as more people gather.

Control of CO2 in a naturally ventilated classroom

Control of CO2 in a naturally ventilated classroom. The ventilation performance of a naturally ventilated classroom was investigated to monitor the CO2 levels and compare compliance with new guidelines. Measurements of CO2 levels were taken for 1 week during the heating season while different ventilation modes were investigated. The classroom was shown to have adequate ventilation to provide ...

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 ...
