They do not always deliver the intended ventilation to the occupants, their real performance is hard to check and they do not adjust minimum outdoor air intake as the ventilation demand varies. Demand control ventilation (DCV), based on sensing the rise in space CO 2 concentration, can address these problems 8,9 but is difficult to apply to multiple space systems. Supply air CO 2 control (SACO 2) effectively applies CO 2 technology to recirculating systems. It is inexpensive, saves energy, and helps ensure good indoor air quality.
