Demand Control Ventilation

Adjust ventilation automatically with DCV

By exchanging stale indoor air with fresh outside air, ventilation systems help increase the comfort and productivity of building occupants.

Typically, ventilation systems exchange air at the same volume 24/7 whether the building is vacant or full, wasting energy and money. Demand Control Ventilation (DCV) uses sensors to monitor and control airflow based on the level of occupancy at any given time.

What you need to know about DCV systems

DCV systems adjust the rate of airflow based on the level of occupancy in the space. This helps remove pollutants resulting from activities occurring in the space, with carbon dioxide (CO2) being the most common type of pollutant.

A common component in DCV systems is a CO2 sensor, which automatically adjusts the amount of fresh outside air your building uses, based on occupancy.

Optimizing building control to save energy

“DCV is an essential control strategy for buildings with unpredictable occupancy, including theatres, gyms, auditoriums, retail stores and more.”
George Hantzis, Energy Solutions Advisor, Enbridge Gas
