GSO ASTM D6245:2021 Scope
1.1 This guide describes how measured values of indoor
carbon dioxide (CO2) concentrations can be used in evaluations of indoor air quality and building ventilation.
1.2 This guide describes the determination of CO2 generation rates from people as a function of body size and level of
physical activity.
1.3 This guide describes the experimentally-determined relationship between CO2 concentrations and the acceptability of
a space in terms of human body odor.
1.4 This guide describes the following uses of indoor CO2
concentrations to evaluate building ventilation–mass balance
analysis to determine the percent outdoor air intake at an air
handler, the tracer gas decay technique to estimate whole
building air change rates, and the constant injection tracer gas
technique at equilibrium to estimate whole building air change
rates.
1.5 This guide discusses the use of continuous monitoring
of indoor and outdoor CO2 concentrations as a means of
evaluating building ventilation and indoor air quality.
1.6 This guide discusses some concentration measurement
issues, but it does not include or recommend a method for
measuring CO2 concentrations.
