  1. The enclosures may be reported in the eio output with Output:Surfaces:List,ViewFactorInfo;. This lists every enclosure for both solar and radiant exchange (they can be different depending on the user inputs in the air boundary surfaces) along with surface-to-surface view factors.

  2. Grouped solar enclosures use the global solar distribution option. If the resulting zone in non-convex, then FullInteriorAndExterior may have problems. Nothing special has been implemented to handle this.

  3. (and 4.) The error message implies that some pair of interzone surfaces are not using the same Construction:AirBoundary object. Need to see the offending idf file to answer with certainty.

I'll also post some comments on the questioner's self-answer.
