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." "2616" "None" "LEED Interpretation" "1485" "2006-05-16" "New Construction, Schools - New Construction, Core and Shell, Existing Buildings" "This is an EAc2 administrative clarification ruling regarding the sale of Renewable Energy Credits (RECs), valuation of on-site renewable energy generation, and separate ownership of the building and the on-site system." "In a previous ruling (EAc2.1 CIR Ruling 12-23-02), it was determined that the sale of Renewable Energy Certificates (RECs) from an on-site renewable energy system was prohibited if that system received EAc2 points. This ruling is an update and supersedes the previous ruling. This ruling also establishes requirements to be met if the building owner does not also own the on-site renewable energy system. To encourage the greater development of on-site renewable energy systems, the sale of RECs is allowed from an on-site renewable energy system that claims credit under EAc2 if the building owner or energy system owner, either separately or acting together, meet the following conditions: 1. They purchase an equivalent number of RECs equal to 200% of the system\'s annual rated energy output each year from another source, which must be Green-e eligible. The system\'s rated output must reflect all system performance characteristics as well as actual local site conditions (e.g., climate, mounting location and angles, etc.). The rationale for the 1-for-2 ratio is that many states have set Renewable Portfolio Standards and in-state renewable energy targets that can be traded in the form of credits. These in-state RECs are typically more expensive to achieve and typically cost a lot more (e.g. $0.05/kWh for New England wind power vs. $0.01/kWh for RECs from West Texas or Dakotas wind). From an environmental and financial perspective these are not the same for a couple of reasons: a. Emissions reduction impacts other than CO2 are less in remote areas than in the congested areas in state where population is concentrated and where RECs are largely purchased. b. Distant renewable energy generation may be stranded by limited T&D capacity. Given that in-state RECs create more benefits than out-of-state RECs for non-CO2 impact but equal for CO2 impact, it was decided to allow in-state to be replaced by out-of-state on a 1 for 2 basis. This allows green building projects to capture the value of RECs created by on-site renewables while resulting in net reduction of CO2. 2. The seller of the on-site RECs must fully follow all established guidelines for the sale of RECs and not claim any of the environmental attributes for the on-site system. Example: An on-site solar system in New Jersey produces 100,000 solar kWh per year. These RECs may be sold provided the building or solar system owner purchases 200,000 kWh of Green-e eligible RECs to offset the sale of the on-site solar RECs. The offset purchase must occur for every year in which the on-site RECs are sold and are in addition to any RECs purchased to meet EAc6. To determine the value of the energy cost savings in EAc2 compliance calculations, the project team may include both of the following components, each of which must be listed separately in the credit documentation: 1) the cost of the energy no longer purchased from the supplier because of the on-site generation; and 2) the actual and/or fair market value of the RECs sold. If an on-site renewable energy system is owned and operated by an entity other then the building owner, the following must also occur to receive credit under EAc2: 1. There must be at least a 10-year contract for the purchase of the energy output by the building owner. 2. There must be clear documentation for accounting purposes whether the purchase includes the RECs or just the energy output. 3. If the purchase does not include the RECs, the building owner or energy system owner, either separately or acting together, must make the 200% offset REC purchase referenced above for at least 10 years.

" "None" "None" "X" "LEED Interpretation" "1507" "2006-07-07" "New Construction, Schools - New Construction, Core and Shell, Existing Buildings" "This is an administrative ruling posted by USGBC updating the definition of qualifying renewable energy. This ruling covers two aspects of that definition." "First, the LEED-NC v2.2Reference Guide First Edition (October 2005) includes a clerical error regarding the eligibility of bio-fuels. Table 3, p. 199 only references electricity production from bio-fuels, whereas it should reference all energy production from bio-fuels. Any energy produced from the eligible fuels qualifies for points in EAc2, and any energy produced from the ineligible fuels does not qualify. Second, LEED-NC v2.2 uses a broader definition of renewable energy compared to v2.1 that provides more flexibility for project teams. This administrative ruling authorizes v2.1 projects to use any of the allowable forms of renewable energy described on pp. 198-199 of the v2.2 Reference Guide. The eligible and ineligible forms of renewable energy are summarized in the following tables: Table 1: EA Credit 2 Eligible On-Site Renewable Energy Systems " "None" "None" "X" "LEED Interpretation" "1842" "2007-07-19" "New Construction, Existing Buildings, Core and Shell, Schools - New Construction" "This is an administrative ruling posted by USGBC updating the conditions that must be met for a project to take credit for renewable energy under EAc2." "A previous ruling (EAc2.1 CIR Ruling 10-03-2006), defined conditions that must be met for projects to qualify for renewable energy credits under EAc2. This ruling updates the previous ruling defining alternative conditions for projects to qualify for EAc2 renewable energy credits. A project will be eligible to achieve points under EAc2 and qualify for renewable energy credits for the system under EAc1 if the project meets the following conditions: 1 The renewable energy system is installed within the boundaries of the project or on the project site. 2 The renewable energy system is connected immediately adjacent to the utility meter. 3 A 10-year (minimum) contract for on-site generation with the owner of the Energy System is established. 4 The RECs associated with the renewable energy system are not sold. 5 The Energy System owner does not count the RECs associated with the renewable energy system to meet a mandated renewable portfolio standard goal or provides the RECs to the project owner.

The intent of this credit is to ""encourage and recognize increasing levels of on-site and off-site renewable energy in order to reduce environmental impacts associated with fossil fuel energy use."" The USGBC\'s guidelines in LEED-EB are not in synch with policy standards from Center for Resource Solutions (CRS) for Green-e Energy, WRI\'s guidelines for addressing Scope 1, 2 and 3 emissions or general industry accepted best practices. The problem relates to USGBC in LEED-EB requiring the calculation of TOTAL LOAD from ALL ENERGY SOURCES(including natural gas, steam heat, propane, etc.) on the building energy use side to set the amount of offset; while Green-e Energy states that REC\'s cannot be used to offset anything other than direct electricity generation (scope 2 emissions). As stated on p. 15 of the Green-e Code of Conduct: B. Communicating the Emissions Avoidance Value of a Green-e Energy Certified Product Green-e Energy Certified renewable energy products must be denominated in megawatt-hours (MWh) or kilowatt-hours (kWh). Consistent with this policy, Participants can market their certified products as instruments to address the environmental impacts associated with the consumption of electricity. One aspect of these impacts is the indirect carbon dioxide emissions arising from the purchase of electricity generated through the combustion of fossil fuels, classified as ""Scope 2"" emissions by the World Resources Institute\'s Greenhouse Gas Protocol. The explicit marketing of Green-e Energy Certified renewable energy products as a means to reduce or offset emissions from anything other than the consumption of electricity purchased from the grid shall not be permitted. Additionally, every other LEED type (NC, CI, CS, etc.) only requires the project owner to offset some percentage of the building\'s electricity use. LEED EB 2.0 and LEED EB OM are the only versions that (mistakenly) include non-scope 2 emissions. We propose to earn EA Credit 2.1 by offsetting only our scope 2 (electricity) emissions, in the percentages outlined in the credit. This will provide consistency with other LEED types and, most importantly, align with Green-e and WRI guidance on the issue. Further, it would seem that fewer LEED EB projects are choosing to use green power than LEED NC, CI, or CS projects, due in large part to the higher costs associated with offsetting scope 1 and 3 emissions in addition to scope 2. Allowing projects to earn this credit by offsetting only scope 2 (electricity) emissions should actually increase the number of participating projects, thus encouraging increasing levels of off-site renewable energy (aligning with the intent of this credit)." "The proposal to offset only electricity emissions in the percentages outlined in the credit would not be acceptable to earn EA Credit 2. In order for a building to be considered climate neutral, all fuel consumption by building uses must be addressed including direct fossil fuel use. Secondly, in addition to climate neutral considerations, the decision to include total load from all energy sources as a basis for LEED-EB v2.0 EAc2 offset level requirements was made during the lengthy LEED-EB pilot program process to help address thermal energy sources and provide a better fit with the U.S. EPA\'s ENERGY STAR Portfolio Tool utilized for LEED-EB EAp2 and EAc1. In regards to offsets, with the release of programs like Green-e climate to complement Green-e energy, the USGBC agrees that Green power or REC purchases or the equivalent should only be used to offset electricity use, Scope 2 emissions. Scope 1 & 3 emissions from natural gas, purchased steam, fuel oil, or propane use should use carbon offsets, verified through a program like Green-e climate or equivalent. Concerns raised above regarding the encouragement of greater participation rates for this credit are always addressed as part of new EB rating system versions and could be accomplished by making adjustments to the required minimum threshold levels as readily as through significant changes to the credit requirements.

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.
