I can think of 2 ways to model this.
1) use supply registers (I assume AirTerminal:SingleDuct:Uncontrolled
) in all zones and ensure that supply air flow rate to bathrooms and kitchen meet or exceed exhaust air flow rate. The supply air will end up there anyway given the draw from exhaust fans, although I expect the exhaust fans will be scheduled and not operate continuously resulting in over-cooling at times when the exhaust fans are off.
2) use ZoneMixing
objects to transfer air to the bathrooms and kitchen from a zone or zones where fresh air enters. Use the same schedules and flow rate for exhaust fans and zone mixing objects. When the exhaust fans are not active, use CrossMixing
objects to exchange energy between the non-conditioned zone and conditioned zones (at a flow rate of your choosing). This method better represents how a zone without supply air would respond to exhaust air flow.
