The control of outdoor air intake rates in mechanically
ventilated buildings based on indoor carbon dioxide
(CO2) levels, often referred to as CO2 demand controlled
ventilation (DCV), has the potential for reducing the
energy consumption associated with building ventilation
in some commercial and institutional buildings. Carbon
dioxide DCV has been discussed, promoted, studied and
demonstrated for the last twenty years, but questions
remain regarding the actual energy savings potential as
a function of climate, ventilation system features, and
building occupancy. In addition, questions exist as to
the indoor air quality (IAQ) impacts of the approach
best way to implement CO2 DCV in general and in a given
building. This report presents a state-of-the-art review
of CO2 DCV technology and application including
discussion of the concept and its application, and a
literature review. In addition the regulatory and
standard requirements impacting CO2 DCV are also
