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 & Shell: Electricity Use

The electricity use determined by the whole buildinig simulation simulation in EAp2 is including also plug load on the tenant spaces (not part of the core&shell scope of work). Eac6 is automatically linked to the whole building simulation of EAp2. Thus the energy use which is the base for EAc6 is including the electricty for the whole building. As the lessor who is the project owner just pays the electricity costs for the public area (not tenant space) the calculation base (electricity use of whole building) seems not to be applicable. Each tenant will have his independant electricty contracts. However it is not possible to adjust the numbers in the tempate. Is there a bug in the template or what is the reason behind this?

If the form does not automatically adjust based on the square footage of core space (see PIf5) then you can provide an explanation and calculations to show what you have purchased. Just work around the form if it is not working as you would expect. You can prorate the core space and only buy green power for that with a minimum of 15% of the total square footage. RECs are so cheap that many projects just base their purchase on the whole building usage.

I understand the owner can purchase for the C&S area only as long as it is at least 15% of gross sq footage of entire bldg. But in that case, does the contracting requirement of 35% electricity consumption apply to the whole building (i.e. contract for usage by C&S as long as the resulting contract amount is at least 35% of entire building usage) or does the 35% then apply only to the C&S portion? It seems a hard sell to have an owner contract for 100% when he can contract for 15%.

The green power purchase is only required for the CS area of the building.
