Recommended CO2 Levels for Optimal Building Performance

Sotirios Papathanasiou2 Comments

Carbon dioxide (CO2) concentration is a critical indicator of indoor air quality (IAQ) and plays a significant role in building performance. While CO2 itself may not be directly harmful at typical indoor levels, its concentration serves as a proxy for ventilation effectiveness and the potential buildup of other indoor air pollutants, including pathogens, that can negatively impact occupant health and cognitive function. This article examines the relationship between CO2 levels and building performance, drawing upon research findings and expert insights to recommend CO2 levels that promote a healthy and productive indoor environment.

Understanding the Role of CO2 in Indoor Environments

CO2 is a natural component of the air we breathe, but its levels can increase significantly in indoor spaces due to human respiration and other combustion processes (candles, cooking, combustion heating, etc). When ventilation is inadequate, CO2 from these sources can accumulate, leading to elevated concentrations.
