Hi,
we are working on a project that will implement a CHP unit serving a residential and a commercial development of which the commercial one being will be certified.
Both projects are run by the same investor.
The CHP will run on biofuels consisting of 70% biomethane generated from energy crops such as cereals, maize, sugar beet and 30% biomethane generated from resources such as pig manure and wildflower nursery.
The biomethane is not generated on site but purchased from local utility company.
Generated energy, both heat and electricity will only be used in the above mentioned projects.
Will this setup comply with Eac2?

There is precedence for using an off-site renewable system and having it count for EAc2. You could review the applicable LEED Interpretations, cite the applicable ones as justification for your situation. You could also submit an Interpretation if you wish a more project specific response from GBCI.

Hi Marcus,
thanks for your response!
Finding what i need in the interpretations takes a bit of time.
Here is what i found in "2009 missing Manual", pg.46:
“To qualify as an eligible on-site system, (…) if the fuel source is not owned, and in cases where use of a substitute, non-renewable fuel is possible, projects must enter into a 2-year contract for purchase of the renewable fuel source, with an ongoing commitment to renew for a period of 10 years total.”
Would that be an option for credit compliance?
Thanks!

Certainly sounds like an option. If you are buying the fuel for the CH,P LEED wants to make sure that the fuel sources will not change over time.
