17 March 2025, Webinar – Recent standards and guidelines on CO2 application and interpretation

Indoor carbon dioxide concentrations have been measured and discussed in the context of building ventilation and indoor air quality (IAQ) for more than 100 years. In recent decades they have been proposed as an easy way to evaluate the adequacy of ventilation, even to estimate ventilation rates, as well as an indicator of IAQ. Many of these proposals and applications of CO2 have been technically incomplete if not wrong. The application of indoor CO2 concentrations, as well as their misinterpretation, has increased in light of the COVID-19 pandemic. That said, standards and guidance have been developed to clarify the application and interpretation of indoor CO2 concentrations. This webinar will provide information on those developments with the intent of advancing the dialog on this important topic.

This webinar is organised by the AIVC and facilitated by INIVE.
