Air Exchange Rate (ACH)

Understand how often the air in a room is replaced with fresh air using the estimated Air Exchange Rate (ACH) and Airflow (currently in API only) virtual sensors.


Gauge ventilation efficiency

Check if a building's ventilation system is operating correctly and make adjustments to enhance indoor air quality.

How Ventilation Rate helps you to:

Verify ventilation rates

Improve indoor air quality

Enhance indoor air quality by understanding air exchange rates. A higher air exchange rate generally indicates better ventilation, thereby improving indoor air quality and reducing transmission of airborne viruses. Adjust ventilation and monitor Air Exchange Rates or Airflow to verify that changes have the desired effect on improving indoor air quality.

Optimize energy usage

Drive energy efficiency

Optimize ventilation systems based on occupancy data and CO₂ levels in the Airthings for Business Dashboard. Use data gathered from actual usage to determine whether you are under or over-ventilating your building and to inform ventilation schedules, rather than relying on a traditional office hours schedule. Ventilation Rate can also enable demand controlled ventilation (DCV) in existing buildings.
