CO₂ Monitoring Advances Air Quality and Energy Efficiency

Buildings At the Moment, Helping Facilities Professionals Make Smarter Decisions

HVAC engineers have long known that monitoring carbon dioxide (CO₂) is helpful in controlling indoor air quality; however, until recently, the practice was discouraged by the cost of the sensors and the efforts required to install, monitor, and calibrate them.

Today, CO₂ monitoring is growing. With the advent of LEED, the increase in digital controls in buildings, and the wider availability of the sensors, CO₂ monitoring is becoming standard practice. In part, this is because the control manufacturers can now link to sophisticated computer networks capable of managing every device in a building; in part, it’s because CO₂ monitoring can also play a role in reducing energy costs. In some cases, it can even reduce equipment capital costs by reducing peak heating and cooling loads.
