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?

Hello, my project is going for Net Zero energy consumption and we were planning on going for the EAc6 - Green Power credits. Can I take automatic credit for EAc6 and and Innovation credit, just because the building isn't using more than it is producing? How would I document this? Otherwise, I don't know how to calculate the Green-E req's that I would typically need to purchase. Any ideas?

Yes. This situation is addressed in LEED Interpretation #10219. http://www.usgbc.org/leed-interpretations?clearsmartf=true&keys=10219

Hi Lisa, can I ask what ended up happening in your situation?  I am in a similar case and still a little unclear of the LEED interpretation. Is it saying that if i can't show the project meeting net zero for 2-years post occupancy, then the project must purchase 35% of their electricity usage? Is it all or nothing - if you can't prove you are meeting net zero then you must purchase the full 35% as the credit originally requires?

It is not 35% or 70% of the total usage. It is 35% or 70% of the power which has not been offset by renewables. This is what the credit would require in all cases.

Ok, thank you Marcus. That was thinking, but I became so confused with how to approach the zero energy situation and then furthermore after reading the interpretation. Thanks much!

Ok, one more question, if using actual electricity utility consumption data, LEEDuser provides the following calculation: Total Required Green Power Quantity = Actual electricity consumption (kWh)  X  50%   X   2 years. 100% for exemplary performance. What is the rationale behind using 50% instead of the design case usage 35%.

My guess is that is a typo. It should be 35% for NC projects.

Thanks, Courtney and Marcus! I fixed the error. Sorry for the confusion.
