On March 11, 2020, the World Health Organization declared the novel coronavirus (COVID-19) outbreak a global pandemic. As noted by ASHRAE and the Centers for Disease Control and Prevention (CDC), engineering and other controls should be part of a broader

Indoor Carbon Dioxide Metric Analysis Tool

June 14, 2022
Author(s)
Andrew K. Persily, Brian Polidoro
Indoor carbon dioxide has been used for decades to evaluate indoor air quality (IAQ) and ventilation. However, many applications of CO2 as an indicator or metric of IAQ or ventilation reflect a lack of understanding of the relationship between indoor CO2

Indoor Carbon Dioxide Metric Analysis Tool
