We have a building with a large area of lockers/toilets. According to ASHRAE 62.1 these spaces do not require ventilation air. These spaces do require exhaust air.

Due to the large area of these spaces and minimal conditioning requirements, these spaces are being served by a dedicated 100% OA unit that heats and/or ventilates only.

Since these spaces are not required by ASHRAE 62.1 to be provided ventilation air, do these units need air flow monitoring? (The rest of the facility will have airflow monitoring as required). Yes, these serve non-densely occupied spaces only.

If yes, CT's on the fans meet the requirements per CIR ID #2099, right?
