We are working on a Hotel project in Chicago, Illinois (USA) with LEED NC v2009. Is my understanding correct in that for credit EAp2 you can follow LEED v.4, and for EAc1 you can follow LEED v.2009 - Ruling 10421?

We are currently achieving 13.5% over baseline when using ASHRAE 2010, this results in the following:

EAp2 LEED v.4 Compliance Path - Prerequisite achieved (5% min.)

EAc1 LEED v.2009 - Per Ruling 10421 - 7 points achieved (per conversion table included in Ruling 10421)

Thank you, any feedback would be great.

That is not exactly correct but close enough. You simply follow the adjusted minimum and point scale in the document you reference. This is entirely a LEED 2009 alternative compliance path and does not really cross over to v4 although the compliance path in both for the prerequisite is essentially the same.
