Re: [EnergyPlus_Support] Zone Infiltration - Design Flow Rate
The AirflowNetwork object will override the ZoneInfiltration object when
an airflow network simulation is performed.
Did you change the AirflowNetwork control setting?
AirflowNetwork:SimulationControl,
AriflowNetwork_All, !- Name
>>>> MultizoneWithDistribution, !- AirflowNetwork Control
The choices for this input are:
\key MultizoneWithDistribution
\key MultizoneWithoutDistribution
\key MultizoneWithDistributionOnlyDuringFanOperation
\key NoMultizoneOrDistribution
\default NoMultizoneOrDistribution
