co2 control for classroom space

Identifying poorly ventilated areas and using CO2 monitors

Check that mechanical systems provide outdoor air, temperature control, or both. If a system only recirculates air and has no outdoor air supply, the area is likely to be poorly ventilated ; Identify areas that feel stuffy or smell bad ; Using carbon dioxide (CO2) monitors. People exhale carbon dioxide (CO2) when they breathe out. If there is a buildup of CO2 in an area it can indicate that ...

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 ...

Indoor Air Quality in Classrooms and COVID19 CO2 Meter

Since outdoor air is approximately 400ppm, indoor CO2 levels should be no more than 1,100 ppm. Note that this guideline is not designed to limit the amount of CO2, but rather to indicate that a proper level of clean air (1520 CFM/person) is being distributed in indoor spaces like classrooms, offices, and churches. And OSHA and the US Green ...
