Hello,

I'm currently modelling an office building pursuing ID&C V4.1 compliance, in France. The client has a contract with an electricity supplier that states that the building will be supplied with 100% renewable energy, but is struggling to have a certificate that that energy comes from a plant that would fall under Tier 2 criteria of the Renewable energy credit(renewable energy plant that has been built within the 5 years before the contract date or that will be operational 2 years after the occupancy date). As such, at this stage, we're considering that renewable energy will fall under Tier 3.

As per EAp2/c2 credit language, the project may not take into direct consideration, either for compliance (EAp2) or credits (EAc2) any renewable energy that would fall under Tier 3 in the renewable energy credit.

My doubt resides in the GHG kgCO2.eq/kWh(pe) conversion factors.

1) Eap2 credit language states that we should follow the "European Environment Agency (EEA) – National emissions reported to the United Nations Framework Convention on Climate Change (UNFCCC) and complete energy balances from Eurostat" values, but I wonder if I may present my case to USGBC, showing them my contract (100% renewable energy supply) and decrease to "0" (zero) those convertion factors. 

2) if so, may I apply thagt only to the Proposed Design? Or I have to apply the "0 kg.CO2.eq/kwh(electric primary energy) to both buildings?

Does this make any sense for anyone?

Please share your thoughts and thank you all in advance!
