Supply air CO2 control (SACO2) is a technique for measuring the outdoor air fraction in the supply air and controlling the outdoor air intake. It is applicable to recirculating systems serving multiple places where ventilation targets are based on outdoor airflow rate per person. SACO2 offers significant benefits : energy savings, simple maintenance, adequate ventilation and ability to measure and record performance.
