[EnergyPlus_Support] The Airflow Network, Infiltration, and Mechanical Systems

["samuel.brunswick" <samuel.brunswick@xxxxxxxxx>]

I'm attempting to use the Airflow Network to model dynamic infiltration in my building. I'm using the "MultizoneWithoutDistribution" setting. The model has a VAV system and I'm wondering, will the Airflow Network take into account pressurization from the mechanical system when it calculates infiltration rates?

My hunch is that the AFN doesn't account for the mechanical system pressures, because I'm seeing increased infiltration rates during periods when the fan is on and I would think that the fan would give the building a positive pressure and thus the infiltration rates would decrease.

Anybody know for sure?
