Created a simplified lab building model in EnergyPlus with high OA/total air change rate (6 ACH), however, the simulation results show actual airflow is not following specified air flow rate in EnergyPlus.

In this 4-zone lab building, I created 3 simple lab zones and one mechanical room. The minimum OA and minimum air flow for labs are 6 ACH according to the design (100% OA). I had entered 6 ACH in Sizing:Zone - Cooling Minimum Air Flow(converted to m3/s), AirTerminal:SingleDuct:VAV:Reheat, m3/s) and DesignSpecification:OutdoorAir objects, and followed this post, I assigned DesignSpecification:OutdoorAirobjects to AirTerminal:SingleDuct:VAV:Reheat, in order to enable OA-controlled ventilation.

The simulated ventilation rate hardly rises above 4 ACH for any of the lab spaces. Is there anything else I had missed to specify the min air flow? Could you please share your strategies to mandate the minimum air flow in EnergyPlus model for an air-flow-driven space.
