The design for a current building involves installing CO2 sensors in the return duct of each densely occupied space rather than inside of the space itself. Since the LEED v4 BD+C handbook states Co2 monitors must be between 3 and 6 feet above the floor, does that mean the CO2 monitors for this project are ineligible because they are too high up?

Hi Edgar, did you ever get an answer on this? I'm having the same issue on a current project. Thanks!

Hi there,
I think we are dealing with two different requirements:
-CO2 sensors located between 3 and 6 feet above floor level are intended to trigger an alarm in naturally ventilated spaces so that occupants can open the operable windows to ventilate the room.
-CO2 sensors in the return duct are necessary to comply with a Demand Controlled Ventilation (DCV) which provides outdoor air when a densely occupied space is in use and provides minimum airflow in order to save energy when the space is empty (auditoriums, theatres...).
I hope that helps,
Edgar Arevalo

Oh wait... nevermind guys. I just took a look again at the LEED v4 BD+C handbook, under page 652, and it says "CO2 sensors installed in return air ducts cannot be used to meet the requirements"
Pallavi, looks like there's the answer. Now I gotta get back to the designer to change installation of those sensors.
