Some office rooms in my model have a continuous air supply while the meeting rooms have variable airflow depending on the CO2 concentration in the room (temperature and humidity are the same as for the other rooms). I've included a Controller:MechanicalVentilation for the VAV. As the other rooms are on the same loop, I get the following warning + an error about the people in those rooms:

1: Warning * Zone name = LEVEL1:1.08GANG is not accounted for by Controller:MechanicalVentilation object name = VAV MECHANICAL VENTILATION CONTROLLER * ~~~ * Ventilation per unit floor area has not been specified for this zone, which is connected to * ~~~ ** the air loop served by Controller:OutdoorAir = AIR LOOP AHU OUTDOOR AIR CONTROLLER. Simulation will continue...

2: Warning * PEOPLE object for zone = LEVEL0:0.34VERGADERZAAL is not accounted for by Controller:MechanicalVentilation object name = VAV MECHANICAL VENTILATION CONTROLLER * ~~~ * A "PEOPLE" object has been specified in the idf for this zone, but it is not included in this Controller:MechanicalVentilation Object. * ~~~ ** Check Controller:MechanicalVentilation object. Simulation will continue.

Should this be linked to a different node in the air loop?
