I'm using AFN in my building model.

I want to know the infiltration load from the specific surface (e.g. the exterior envelope of the room no.1, the internal wall of room no.2).

What is the name of the output variable that calculates infiltration sensible heating rate?

After running the simulation, have you looked at the available output variables in the .rdd file?

Yes, I have looked. But, I can only find about the zone, not the surface...

Are you looking for these?

Output:Variable,*,Zone Infiltration Sensible Heat Loss Energy,hourly; !- HVAC Sum [J]
Output:Variable,*,Zone Infiltration Sensible Heat Gain Energy,hourly; !- HVAC Sum [J]

I'm looking for the infiltration load from the specific surface, not the zone. Thank you for your suggestion.

If your zone has only 1 exterior wall, and ZoneInfiltration:DesignFlowRate / Design Flow Rate Calculation Method is specified as ExteriorWallArea, then the zone infiltration would be equivalent to the surface infiltration. This is the only way I know of to get the infiltration through a specific surface.
