Abstract

Indoor CO2 concentrations are often discussed in the context of ventilation and IAQ, most recently in relation to airborne infectious disease transmission. However, many applications of indoor CO2 measurements do not reflect a sound technical understanding of the relationship between indoor CO2 concentrations, ventilation and IAQ. ASHRAE has issued a Position Document on the role of indoor CO2 that addresses CO2 as a metric of IAQ and ventilation, impacts of CO2 on building occupants, indoor concentration measurement, CO2 for controlling outdoor air intake, and how indoor CO2 relates to airborne infectious disease transmission.
