color:#0025C4'>It depends, but the best way would be to model it as exhaust air
in the zone (air side HVAC). If you are trying to assign a schedule to it, it
gets trickier. You probably want to assign it as a design flow then (under the
airflow tab) and assign a flow schedule to it. You’ll need to specify 100%
OA at the system level in this case. <o:p></o:p></span></p>
