Carbon Dioxide (CO HVAC Basics - Honeywell

CO2 levels within a conference room can reach 2,500 ppm while the level on the other side of the door remains at 800 ppm. Therefore, sensor placement strongly affects the result because the control system attempts to control CO2 levels at the sensor location. There are a variety of CO2 control strategies and algorithms used in ventilation ...

It is important to note that CO2 is not considered a contaminant or pollutant at the levels normally measured in buildings (400 to 2000 ppm). It is however widely recognized as an indicator of ventilation rates inside buildings. Certain levels of CO2 indoors correspond to various cfm/person ventilation rates. The chart below shows this relationship.
