Demand controlled ventilation

Demand Controlled Ventilation (DCV) is automatic adjustment of ventilation equipment according to occupant choice. DCV is a control method that modulates the volume exchange of fresh or outside air into an enclosed space by mechanical air conditioning equipment. Design engineers reference a codified standard when determining ventilation set points in order for sensors or time schedules and control loops to achieve indoor air quality.

There is a significant energy saving potential in rigorous outdoor air control. [1]
