Abstract

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.
