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

EAc1 baseline and proposed systems

The problem I am having is that I have to select a system for the baseline model which is System 7 VAV with Reheat, based on the advise of ASHRAE Table G3.1.1A , however the proposed system for the  building is to be a FCU system with a chiller, gas fired boiler and AHU supplying tempered air.  I thought the systems had to be similar in some way.
Or do I just have to have the same amount of AHU's for example?

Sometimes the baseline system is very different than the proposed system. Make sure to follow the full guidance for the baseline system in G3.1.1. For example with a system #7 there needs to be a system per floor so it may not have the same amount of AHUs as the proposed.
