[Equest-users] Documenting ARI conditions

Dear all,           I had a LEED reviewer's comment as follows: 
"Note that section G3.1.2.1 requires that where efficiency
ratings, such as EER and COP, include fan energy, the descriptor shall be
broken down into its components so that supply fan energy can be modeled
separately. Because the efficiency ratings are calculated at ARI-rated conditions,
the fans should also be broken out at ARI-rated conditions. Most simulation
software programs have the capability to perform this step automatically.
Provide documentation showing that this calculation has been performed by the
software automatically or provide calculations consistent with the ASHRAE
90.1-2007 User’s Manual showing that the calculation has been performed at
ARI-rated conditions."
I need to know if any one had previous experience documenting this, and can help me with the best way for covering this point. How can I know if eQuest does this step automatically, and if so what is the best way to document it?
