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 recently issued a Position Document that addresses the role of indoor CO₂ as a metric of IAQ and ventilation, the impacts of CO₂ on building occupants, the need for accurate indoor CO₂ concentration measurement, the use of CO₂ for controlling outdoor air intake, and how indoor CO₂ relates to airborne infectious disease transmission.
