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?

Median Electrical Intensity definition

Dear All,


In what relates to credit EA C6 and following option 2 (Estimate baseline electricity use) for an Office Building, we are considering using a non-default median electrical intensity determined from CBECS 2012 Table C20, Marine climate (climate that applies to this location), 48 - 60 hours per week (119 kWh/sqm/year). This energy intensity indicator is much closer to the energy use intensity expected for the building (based on EAc1 – Whole Building Simulation in aggregate DES/Building scenario) than the default MEI for office building.

 

Is this strategy acceptable?

 

Thanks in advance.

Why are you trying to use the CBECS data when you have modeling results? If I recall correctly when you have a model you have to use it and not he CBECS data.
