A solution that works is as follows:
Add a Maximum Outdoor Air Fraction Schedule to Controller:OutdoorAir which is EMS-controlled (in EMS the condition is defined for setting outdoor air flow to zero). Although this works, this solution is not fully satisfactory because it remains unexplained why EnergyPlus produced a minimum outdoor air flow greater than zero in the first place.
