The system is installed on 10 existing random building rooftops, with another 136 kW phase nearly commissioned on/near a sports field. We pay a small kWh premium, and will take full ownership after 20 years. PV output is dedicated for campus use, utilizing a combination of direct building connections and connections to the campus owned grid. We would like to apply for EAc2 on a campus basis for approximately 9 separate building projects that do not include their own individual PV installations. The cost to buy REC\'s for 10 years for the entire campus system is prohibitive under our current construction budgets. We propose that individual LEED Building Projects apply for EAC2 using the existing onsite PV renewable source, and buy 10-year REC\'s for 100% of the power claimed on the Template, as qualifying on-site renewable energy. The project REC\'s would be redeemed and solely retained by the individual Building Projects, and would not be shared for use on any other projects. Would purchasing REC\'s then restore the ""associated environmental benefit"" to the on-site generated renewable project energy claimed; and meet the sustainable intent of the credit as indicated in the CIR Ruling dated 7/20/2009?" "The CIR Ruling dated 7/20/2009 (#2616), states that if the project sold renewable energy certificates associated with the on-site renewable energy system, the team may not take credit for the system under EAc2, since the system would have no associated environmental benefit. The project teams approach of purchasing 10-year REC\'s for 100% of the power claimed on the Template, to restore the associated environmental benefit is acceptable. The project must provide sufficient documentation to ensure the portion of the on-site renewable energy system designated for each building is not used on other projects. Additionally, the project team should provide documentation, including contractual terms, to verify the purchase of the necessary volume of REC\'s. The project team may not apply any of the REC\'s purchased to restore the associated environmental benefits of the on-site renewable energy system for the purposes of achieving EAc2 towards achieving EAc6, Green Power."

The heat produced by this Cogeneration system will also fully be used on-site to preheat heating hot water and domestic hot water via a heat exchanger and potentially to power an absorption chiller.\n\nThe building will receive the Biogas from a local Biogas provider and plans to enter into at least a 10 year contract with this provider to supply enough Biogas to the building to fully power the planned Cogeneration system. The contract will stipulate both that enough Biogas will be fed into the pipeline to meet required demands of the Cogeneration system and that the Biogas will be metered to prove that the actual amount of Biogas supplied meets the contracted requirements at all times.\n\nThough the Biogas is not being piped exclusively to the site (contractually it is supplied exclusively via project ownership funds), it is transported directly to the site in the existing natural gas pipeline. This approach achieves the exact same net result on the Natural Gas grid as piping Biogas exclusively to the project site in its own dedicated pipeline and allows the project to avoid having to dig up 100s of miles of land and lay a brand new pipeline to the project, something that would have a significantly detrimental effect on the local environment. In an urban environment like where the project is located, there is little or no option to be able to refine and extract Biogas on-site or even very close to a site, so the approach the project team is suggesting is the best and most reasonable alternative.\n\nIs this approach acceptable in accordance with the Reference Guide and Addendum 100001081 (November 1, 2011)?" "Directed Biogas purchase is not considered on-site renewable energy based on the current EAc2 credit requirements, addenda and LEED Interpretations, because the gas consumed on-site is not the same as the biogas that the project purchased. Please note that the referenced Addendum 100001081 does not allow for the fuel used on site to be different than the fuel that was purchased for the project. The referenced addendum applies for situations such as landfill gas piped directly to the project from a nearby landfill, or wood pellets from wood mill residue that are trucked to the project. In either case, it would not be acceptable for the landfill gas or pellets generated from wood mill residue to be ""purchased"" by the project, used in another project, and replaced in the project with natural gas or wood pellets produced from tree tops. Also, note that NREL refers to directed biogas as off-site renewable energy." "10126, 100001081" "None" "X" "X"
