Laboratory experiments were performed to evaluate the effect of different CO2-based demand-controlled ventilation strategies (on/off, proportional, linear, PID) on energy consumption and indoor air quality, with various ventilation rates and occupancy profiles, and with one- or two-zones controls. Results show the capability of different strategies to maintain acceptable indoor CO2 level with the minimum outdoor air requirement.
