[BLDG-SIM] Energy-10 and LEED

[Marcus Sheffer]

Energy 10 software is acceptable for LEED even though you are correct on 
ECBM in 90.1.  The LEED Reference Guide lists some exceptions to the 90.1 
ECBM.  For the proper building type and systems, Energy 10 would be 
acceptable according to my understanding.
