[Bldg-sim] Really need some deep DOE-2 theology on this one..

[Joe Huang]

John,

I can comment only on the DOE-2 side of things.  When you say "one of 
the spaces claims an Exterior surface between them",  you must mean just 
by geometrical
proximity, not explicitly with a "NEXT-TO" command ?   Because as far as 
I'm aware, only an INTERIOR-WALL can have a NEXT-TO command.  If these 
roofs are specified as EXTERIOR-WALLs or ROOFs (the only difference is 
the default TILT), they can't have a NEXT-TO and will be modeled as 
exposed to the exterior environment, including solar.  Self-shading from 
other exterior-walls will be considered only if those are specified as 
shading surfaces (though I've forgotten exactly how that's done 
SHADING-SURFACE = YES ?).
