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. This sensor location has been approved on all of our LEED installations to date." Any thoughts on this?

C02 Sensors in the return ductwork can be very informative to your system's operation when serving large non densely occupied spaces with a central return duct. However, it does not meet the requirements (of this credit) for CO2 sensors in each densely occupied space.

Maura, what did you end up submitting for this credit? Have you received your review back and did it pass with the sensors in the return air ducts?
Thanks!

if you listen to the principles of LEED webinar it clearly states that it cannot be in the return duct work... needs to be 3'-6' above the finished floor. I'd advise the Honeywell representative to look at the LEED Online form :)
