FAQs about EAc4 :

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?

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?

CI-2009 EAc4:Green Power

Actual Power Usage

Hi, We are in the midst of our final submission and we have decided to submit for this credit. The building just went online end of January. We have actual energy usage for past 4 months (Feb- End of May) when the building first went online. We were wondering if we can extrapolate the energy usage for the year and use that as the baseline for "EAc4: Option 1: Actual Usage." Let me know when you get a chance, thanks!

Richard, it sounds like you're complicating things for youself. Why not use the results of EAc1 energy consumption expectations, as Option 1 calls for?

If you don't have an energy simulation for the space than you might want to use a green power contractor, which does green power supply based on percentage of your actual consumption. So what every you consume in a month, you will be purchasing 50% green power. I'm guessing you don't want to use the 8 kWh/sf year, because it's more than you actually will be using?

I am trying to document this credit and we have not occupied the building for more than 3 months. So we are not able to document via the "Actual Consumption" route. However, to use the "Design Electricity Consumption" route, "The project space regulated electricity use for green power calculations are based on the design energy cost from the Lighting Power Density section of EA Prerequisite 2 and the Design Case Energy Use from EA Credit1.3 Option 2. (Note: this option shall only be selected if EA Prerequisite 2 and EA Credit 1.3 are complete)." However, we did not complete EAc1.3. We have our Title 24/Energy Model since we are in CA. But this LEED Template explicitly says I have to have completed EAc1.3, which I have not. How do I document this credit since my project is purchasing 100% RECs for two years?
