Hi, the CI project I am working on uses only the base building system supply for meeting rooms with between 2 and 8 people. These rooms are all located internally and only use a temperature sensor to modulate the 100% OA VAV base building system. As the system is 100% OA there is ample ventilation being provided to the space. Also the VAV damper is connected to a temperature sensor that will modulate with the occupant density.
I would like to confirm that our system meets the intent of the credit and that CO2 sensors are obsolete in this senario.
Any meeting rooms with more than 8 people are provided with a supplementary system with temeprature and CO2 sensors.
