FAQs about EAc2 :

The energy cost offset from onsite renewable energy cannot be used to demonstrate compliance with the prerequisite. Can this cost offset still be credited to the proposed energy cost savings for this credit?

NC-v4 EAc2:Optimize energy performance

DEMAND RESPONSE energy modeling

How is it possible to take advantage of energy use reduction due to DR systems in EAp2-EAc1 energy modeling? Is there any reference guide or document as those for the "key cards" for example? Thank you

The DR credit was specifically added to v4 because it is not fully rewarded within the Energy Performance prerequisite and credit. You must use the same utility rate for each model. So you will get some partial savings for strategies like peak shifting. I am not aware of any document that spells out a modeling protocol to demonstrate these savings.
