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.
