co2 control for classroom observation

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 compliance with current recommendations although ...

The 2019 Guide to Demand Control Ventilation

· Carbon dioxide (CO2) is an excellent indicator of occupancy, since all human beings produce similar amounts per hour. In addition, a DCV system with CO2 concentration sensors can tell not only the total occupant load, but also how they are distributed among indoor spaces. This way, the ventilation system can control the total airflow provided, and also how it is split among various zones.
