FAQs about EAc6 :

Our project is outside the U.S. We would like to earn this credit by purchasing RECs, but there are no Green-e options available here. It looks like most Green-e certified power comes from the U.S. What should we do?

We are pursuing this credit outside the U.S., and the owner wants to know if we can buy green power through a provider in our country that is not Green-e certified. We started comparing our national standard to Green-e and quickly found an area where the

Our project will be net-zero energy, i.e. will produce as much or more power than it consumes. Can we earn this credit?

The owner has purchased RECs for a percentage of energy use of its whole portfolio of buildings, or campus. Can we earn this credit for a single LEED building with this purchase?

We plan on pursuing this credit only if we need to do so to meet our certification target, i.e. if another credit we are counting on gets rejected. How late can we apply for this credit?

The owner purchases RECs based on an earlier prediction, but our energy model is now showing that we are just a little short of the credit threshold. What should we do?

CS-2009 EAc6:Green Power

Core and Shell area and Tenants area

Greetings,

Pursuing EAc6, Option 1, for office building registered as C&S for LEED certification, the following issue is kind of not clear to me:

Normally, when a building type is Core and Shell, the idea is the tenents of this  building to be able to complete its Fit-Outs as per their needs.

Following the above, could the terms Core & Shell and Tenant areas be considered as identical for the purpose of Design Energy Cost calculation?

Your support is highly appreciated.

Thanks

For some C&S projects there is no building area that is core, it is all tenant space. In those cases the 15% requirement within the credit language kicks in for the green power purchase.

Marcus, thanks a lot for your answer. I was following also the same logic, just the 15% requirement seemed kind of strange for me. This is because the project I'm working on has a tenant space of 56% of the total GFA. Hope that this is not something unusual, but who knows.... Thanks.

Seems pretty high and I have no idea if it unusual of not. In your case, since the core area is greater than 15%, you would use the actual core area. I suppose you could just use 43% of energy use or you could create the model so that the core space is on a separate meter within the model.
