The REC's provider has no GES equivalent for the amount of kWh we purchased, but we want tp consider this purchased in our LEED submittals.
Should we convert the amount of REC in GES using the GES produced by our energy source or the GES produced by the energy source where the renewable energy (from the REC we purchased) was generated?

Magda - I'm not familiar with "GES"...what does that refer to? Also, are you considering this mostly for inclusion in this credit, or for the renewable energy credit (EAc4)?

Hi Jenny, I'm sorry for the cofusion; we're based in Montreal, Quebec. That abbreviation is French for GHG (Green House Gasses).

Magda, how are you calculating your emissions for electricity use? I'd recommend just figuring out the emissions associated with grid electricity consumption for your building (you can use GRI resources to find national emissions factors, or there are lots of other sources out there), and then deducting from that a percentage equal to the percent of electricity you are offsetting with RECs. If you have purchased RECs equal to 50% of your total electricity use, you can claim a 50% reduction from what would occur none of your electricity emissions were offset. Make sense?
