Abstract:

In some situations, measurements of indoor CO2 concentrations can be used to assess indoor air quality and ventilation. However, oversimplified descriptions of measurement procedures based on CO2 have been presented, and there have been many cases where indoor CO2 concentrations have been misinterpreted. This paper describes the relationship of indoor CO2 concentrations to building air quality and ventilation, with a focus on how CO2 can be used to evaluate air quality and ventilation performance. While CO2 concentrations do not provide a comprehensive indication of indoor air quality, they can be used to assess the acceptability of a space in terms of human body odor. Also, under some circumstances CO2 can be used to evaluate building ventilation, specifically air change rates and percent outdoor air intake.
