Note that according to a 4/1/12 addendum from USGBC, "If an energy model was used to document compliance with EAc1: Optimize Energy Performance, the data from the energy model must be used as the basis for determining the electricity consumption for this credit." I assume most teams would do this anyway, but it's a useful clarification.

Tristan, I'm curious about the tip sheet calculation above that illustrates taking the C&S square footage percentage x the annual energy use from the energy model to establish the energy use to calculate RECs. I don't see that particular strategy in the v2009 reference guide. Is it a modification of the original Option #2 that has become acceptable practice after the 4/1/12 addendum required the use of the energy model information? I have received wildly different approaches from the REC brokers I contacted and want to validate the information before advising my client to make a purchase. Thanks
