FAQs about EAc4 :

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?

I´m trying to set how many RECs I must buy to comply with this credit for a project of 59,545sqf. According to Reference Guide I should multiply this area by 8kWh for 2 years (59,545 x 8 x 2), requiring a 952,735kWh purchase. Althought when filling LEED online template it cames as return a information as "Green Power per sf over a two year period" of 839.7kWh/sf. What does that mean? What calculations should we consider. I´m a lot confused. Thanks, Juliana Malho

Juliana, Not sure if i have understood your query but i note that there must be a problem while you are filling the template. Annual green power requirement will be 59545 x 8kW/sqft/yr which is 476360kW/yr. You need to fill this value in the coloumn "annual green power purchased" and change the contract to 2years. The logical testing is "Green Power per sf over a two year period" should be 8kWh/sqft as this is the value which you have used initially for computing the Green Power to be purchased. Thanks Sriman
