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 ...

Suggested CO Control Sequence Of Operation

2 Control Sequence Of Operation Installation Coverage: One sensor should be used for each zone of major occupancy or per air handling device if a number of devices serve a large zone. If occupancy density/patterns/usage are different in two adjacent areas each area should be considered a separate zone. Generally one sensor can serve up to 5,000 sq feet. Larger coverage is possible in theaters ...

Why Monitor CO2 in Classrooms?

The most obvious method to ensure that a room is properly ventilated, which aids in maintaining a highlevel of indoor air quality, is to monitor Carbon Dioxide (CO2) levels within the classroom. Every time you exhale, you release CO2 into the air. Therefore, the CO2 level lets you determine if the room is being properly ventilated with fresh outside air; thereby, helping you gauge the quality ...

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 ...
