CS-2009 EAc2: On-site Renewable Energy
In a Core&Shell project, the percentage of renewable energy integration shall be refered to the total building energy use (including tenants areas) or only to core and shell energy use ?

Can I pursue this credit if I am using one of the prescriptive compliance paths for EAp2/EAc1?
Can I really double-count onsite renewable energy in both EAc2 and EAc1?
Our PV system is being installed after the building is occupied. Is that okay?

It is based on the whole building energy use.

Hi Marcus,
Regarding this query, why does the LEED Reference guide "CS Appendix 4" list EA Credit 2 under "Case B" credits?
Case B credits are defined as:
"Submittal documentation for Case B credits need only include data from the Core & Shell project scope. If the project team wishes to claim performance improvements based on anticipated tenant work, such data must be supported by tenant sales and/or lease agreements."

So it is actually based on the whole building energy cost (not use as I indicated).
Appendix 4 refers to tenant improvements. If renewables are being claimed as part of work to be done by the tenants then it would be a Case B credit.

Oh okay, makes sense. Thanks Marcus!
