Hi,
We are currently working on an office building, we want to achieve IEQ cr1, by installing C02 monitors in all spaces. (The building has rooms with mini-plits and windows so we will consider these spaces as naturally ventilated for this credit). The problem is the architect doesnt wants the monitors to be fixed to the walls due to esthetics. Can desktop C02 monitors, located in the breathing zone count toward this credit? We will give each executive one to have in their shelves at about 4.5 feet.
Thanks!
Thank you

I think that if you provide a narrative about how each sensor is placed, it is possible to meet the credit requirements. A few things to consider; the reviewer may challenge that the sensor will be moved elsewhere by the occupant, and thus you do not comply. Also, the sensors are required to generate an alarm to the building occupants. Unless you are using wireless transmission to the BAS, this will be a nuisance. I have seen sensors on desk generate readings of around 12,000 ppm while occupants are within 36".
