In this study, we analyze the accuracy and calibration performance of mass-produced CO2 sensors and evaluate their suitability for distributed demand controlled ventilation. We performed experiments in two different settings, namely, a calibration chamber and an occupied laboratory configured as a cubicle complex. In addition, in combination with data from a people tracking system we analyze the relationship between CO2 concentrations in the laboratory and its occupancy. Our studies indicate that despite the inaccuracies in massproduced CO2, they can be used in demand controlled ventilation systems by using well-developed calibration procedures.
