Re: [EnergyPlus_Support] Infiltration input





Oops. Must be thinking of an earlier version and did not realize it changed. Or I'm a total moron. Sorry about that.

Huh?

ZoneInfiltration:DesignFlowRate,
... snip...
  A4 , \field Design Flow Rate Calculation Method
       \note The entered calculation method is used to create the maximum amount of infiltration
       \note for this set of attributes
       \note Choices: Flow/Zone => Design Flow Rate -- simply enter Design Flow Rate
       \note Flow/Area => Flow per Zone Floor Area - Value * Floor Area (zone) = Design Flow Rate
       \note Flow/ExteriorArea => Flow per Exterior Surface Area - Value * Exterior Surface Area (zone) = Design Flow Rate
       \note Flow/ExteriorWallArea => Flow per Exterior Surface Area - Value * Exterior Wall Surface Area (zone) = Design Flow Rate
       \note AirChanges/Hour => Air Changes per Hour - Value * Floor Volume (zone) adjusted for m3/s = Design Volume Flow Rate

Flow/ExteriorWallArea?????

You can also use the ZoneInfiltration:DesignFlowRate object to model infiltration.  Unfortunately, there is no way to enter a cfm/sf of exterior wall area into that object (Linda - request for next release??), but this will respond to temperatures and wind speed.  It is not actually sensitive to the zone orientation, but is much easier to set up than an airflow network.
