As it turns out, there is a definite problem with this input file and all 
input files that have the name 5Zone.....  (more than likely at least).

#1.  I had a missing "ABS" in my azimuth check, so it should have shown up 
in the basic case as well as any rotations.

#2.  Of greater concern is that these two surfaces (interzone) are of 
differing areas and therefore a bigger problem than just a simple -- got 
the outward facing normal wrong.  Somewhere along the way, the check of 
interzone surfaces for the same (or nearly the same -- within 2%) area got 
lost and so didn't get highlighted here.

The differing areas will be a severe error and will terminate the 
simulation.  I.e, will look more like:

Program Version,EnergyPlus, Version 1.1.0
    ** Warning ** Object=RUNPERIOD, entered with less than minimum number 
of fields.
    **   ~~~   ** Attempting fill to minimum.
    ** Warning ** Object=RUNPERIOD, entered with less than minimum number

    **   ~~~   **   Area=55.4 in Surface=SB51, Zone=SPACE5-1
    ** Warning ** InterZone Surface Azimuth do not match as expected.
    **   ~~~   **   Azimuth=45.0 in Surface=SB15, Zone=SPACE1-1
    **   ~~~   **   Azimuth=180.0 in Surface=SB51, Zone=SPACE5-1

And will then terminate.

Sorry for any confusion or inconvenience this may cause.
