Hello Oat; I'm also interested in the answer to your question "...does EP assume that the temperature of the air around the entire building envelope is uniform and equals to the air temperature as specified in the epw weather file for a given hour?" My assumption was that E+ did not perform complex exterior air calcs (like finite element or finite volume solutions)...perhaps I am mistaken!
I was searching around in the E+ engineering reference and came across the following exterior surface object SurfaceProperty:ExteriorNaturalVentedCavity and felt it might be of use.
