The supply CO2 based demand controlled ventilation (S-CO2-DCV) proposed in this paper is one of the strategies that could reduce energy use by reducing the unecessary overventilation of buildings. It is a compromise between the Multiple Space Equation (MSE) and the CO2-DCV technique : both the actual occupancy of the building with the critical zone ventilation requirement are taken into account.
