CO2 MONITORING FOR DEMAND CONTROLLED VENTILATION …

Mar 17, 2010· Carbon dioxide (CO{sub 2}) sensors are often deployed in commercial buildings to obtain CO{sub 2} data that are used to automatically modulate rates of outdoor air supply. The goal is to keep ventilation rates at or above code requirements, but to also to save energy by avoiding over ventilation relative to code requirements.

On the use of CO2 sensors in schools and other indoor ...

Oct 29, 2020· A CO2 sensor measures the concentration of CO2 in the room, expressed typically in parts per million (ppm). A high CO2 concentration thus indicates poor air quality (1, 4) and the need to ventilate a room (3, 4). The measurement typically occurs continuously over time and requires no supervision. A wide range of CO2 sensors is available on the ...
