CO2 sensors in return ductwork? | LEEDuser

28/08/2012· The CO2 sensors for this science building are in the return ductwork, not 3-6' from the floor. I'm telling the team that this is clearly not in compliance, but the Honeywell rep insists otherwise. He writes: "Most schools do not have the capability to utilize return air. The location of the CO2 sensor at your building provides a better representative reading in all areas.
