You are correct that PixelCounting will handle the solar properly (if using FullInteriorAndExterior solar distribution),

@enriquesissa There are multiple places to specify and report OA. Please post a link to the idf.

Installing the Visual C++ Redistributable library should fix things (at least for EnergyPlus, not sure about OpenStudio)

Still the same in v9.6.

It there is no outdoor air, all of the air is recirculated from the zone, so there cannot be any heat recovery.
