The thermal impact of infiltration is included in the zone air heat balance, but not the mass. The default zone air mass calculations do not account for infiltration, so there is no build up of air in zones as you describe. To include the mass balance, you'll need to add a ZoneAirMassFlowConservation object for your zones, or balance the flows manually. You can read more about it in the engineering reference here
