(#8556) CO2 sensors in AHU return air ducts to demonstrate compliance.


For our project, CO2 monitors are planned to be provided in the AHU return air duct. Will this meet the requirement, or they have to be provided in individual regularly occupied areas?


As per appraisal 12.1.2, if CO2 sensors are provided in all AHU's (return air ducts), which are providing for habitable areas, the project is not required to install CO2 sensors in individual conditioned spaces.
Please note- unconditioned habitable spaces are not exempted from the appraisal, therefore, sensors will have to be installed at space level in such habitable spaces.
