Abstract

Carbon dioxide (CO2) based demand controlled ventilation (DCV) has been proposed and implemented for many years as a strategy for increasing energy efficiency by providing outdoor air ventilation rates based on actual occupancy rather than design occupancy. Over the years there have been various simulation studies and demonstration projects, but important questions remain about energy savings potential, indoor air quality impacts, and both when and how to apply the approach. A major element of the CEC-EEB project examined the impact and application of CO2 DCV via a literature review, field demonstrations, energy analysis, and indoor air quality simulations. Based on the results of these efforts, this report presents a number of recommendations on the application of CO2 DCV.
