"The project is requesting that REC\'s purchased from a larger corporation meet the credit requirements on a single project. Yes, this approach is acceptable given that the project has purchased Green-e accredited Tradable Renewable Certificates (RECs) equal to at least 35% (or 50% for LEED-CI projects) of the predicted annual electrical consumption for the project building over a 2-year period.

The final estimation of electricity consumption for EAc1, Optimize Energy Performance, includes the impact of renewable energy determined through EAc2, On-Site Renewable Energy. The credit language for EAc6 indicates that the annual electricity consumption is to be determined from the results of EAc1 or CBECS. Based on this language, it would appear that a net zero energy project would not need to purchase any renewable energy credits (i.e. green power) to achieve EAc6. If a project was 99% better than ASHRAE 90.1-2007 as determined for EAc1, the green power purchase required would be clear, albeit very small. EAc6 seems to conflict with facilities wanting to increase their energy performance to net zero. Please clarify this credit to support projects seeking net zero. " "The applicant is asking whether EA Credit 6 - Green Power, and by extension, EAc6 exemplary performance, may be automatically awarded for projects that are designed to be net-zero in terms of average annual energy use without the purchase of green power or renewable energy credits. \nYes. If the project produces 100% or more of its electricity as on-site generated renewable electricity, as documented in EAc2 - On-site Renewable Energy, the project is eligible to earn EAc6 and one Innovation in Design point for Exemplary Performance in Green Power. However, for any project that is connected to the electric utility grid, the following requirements apply to ensure that the project meets the credit intent if the project does not achieve net-zero performance once built:\n1. If a Green-e certified or equivalent utility program is available to the project in the project location, then the project team must provide a 2-year contract or Owner\'s letter of Commitment indicating that the project will commit to a 2-year enrollment period in the program for at least 35% of the provided electrical energy for EA Credit 6, or 70% of the provided electrical energy for Exemplary Performance in Green Power.\n2. If a Green-e certified or equivalent utility program is not available to the project in the project location, then the project team must provide a letter of commitment signed by the Owner or Owner\'s representative confirming:\na. That a Green-e certified or equivalent utility program is not available to the project.\nb. That the project will review the purchased annual energy consumption for the first two years of occupancy, and will commit to purchase RECs to offset 35% of the purchased electrical consumption for EA Credit 6, or 70% of the provided electrical consumption for Exemplary Performance in 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"
