Description of change:
Replace the definition of "Previously developed sites" with "Previously developed sites are those altered by paving, construction, and/or land use that would typically have required regulatory permitting to have been initiated (alterations may exist now or in the past). Previously developed land includes a platted lot on which a building was constructed if the lot is no more than 1 acre; previous development on lots larger than 1 acre is defined as the development footprint and land alterations associated with the footprint. Land that is not previously developed and altered landscapes resulting from current or historical clearing or filling, agricultural or forestry use, or preserved natural area use are considered undeveloped land. The date of previous development permit issuance constitutes the date of previous development, but permit issuance in itself does not constitute previous development."

LEED Interpretation
Inquiry:
The project team is planning on installing a Cogeneration System that will take Biogas and turn it into Electricity to be used wholly on-site. 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.The 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.Though 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.Is this approach acceptable in accordance with the Reference Guide and Addendum 100001081 (November 1, 2011)?
Ruling:
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.

Inquiry:
Many of the ASTM Standards we reference have been withdrawn, upgraded, or superseded. Provide guidance on which updated standards should be used.
Ruling:
The withdrawn ASTM Standards listed- ASTM E1980-01 and ASTM E903-96- are still the correct references for SSc1: Site Selection, SSc7.1: Heat Island Effect, Non-Roof, and SSc7.2: Heat Island Effect-Roof. These two standards were not withdrawn for technical reasons, but were withdrawn because they had not been updated within 8 years. Testing can still be performed for these as well as the superseded standards. The updated versions of the superseded standards can be used, but are not required:Old: ASTM E408-71(1996), Current: E408-71(2008)Old: ASTM C1371-04a, Current: C1371-04a(2010)Old: ASTM E1918-97, Current: E1918-06 Old: ASTM C1549-04, Current: 1549-09Note: This Interpretations is also applicable to Sustainable Sites Credit 7.2: Heat Island Effect-Roof and Sustainable Sites Credit 1: Site Selection, see LEED Interpretations dated 8/1/2011 ID number 10093 and 10094 respectively.

LEED Interpretation
Inquiry:
There is a stainless steel tube veil that covers the complete building. The tubes are placed with a 1 mm spacing between each other, and the material interior cannot be seen. Therefore, we would like to conduct a test to verify if the SRI of the tubes will comply with the LEED requirements (equal or greater than 78). Due to the originality of the exterior facade, we would like to know what type of test should be conducted:
Option 1 - Test using a 4mx4m mock up of the roof assembly and test the reflectance per ASTM 1918,
Option 2 - A flat sample test of all the materials installed on the roof
Please advise if there are any other tests that would need to be conducted.
Ruling:
The Referenced LEED Standard of ASTM 1918-97 has been superseded by ASTM 1918-06. For a roof with a veil design, or similar non-homogenous materials, the project should perform a SRI test to ASTM E1175 - 87(2009) Standard Test Method for Determining Solar or Photopic Reflectance, Transmittance, and Absorptance of Materials Using a Large Diameter Integrating Sphere. When submitting for LEED Certification, please include a copy of this interpretation and a summary of any testing results that document the SRI rating for the installed veil surface.Projects may wish to test any mock-up to assess credit compliance before testing installed materials, but the testing for certification should be done for the installed roofing assembly.

LEED Interpretation
Inquiry:
Can sidewalks, roads, and other hardscape areas located above a project building\'s underground parking structure, which are required by the governing municipality to be constructed of non-compliant materials, be excluded from the SSc7.2 and SSc7.1 calculations?
Ruling:
Similar to LEED Interpretations #2293 and #3101, sidewalks, roads, and areas that cover un-conditioned spaces (such as parking garages) are considered hardscape or landscape nonroof surfaces. Thus, they should be included in the calculations for SSc7.1 Heat Island Effect- Nonroof. In situations where infrastructure, materials, or surfaces are owned, operated and maintained by the local governing body, project teams may exclude the area of the material from the calculations for SSc7.2 and SSc7.1. This exemption can be applied only if projects do not have any control over the materials used for the surfaces in question. If the materials are owned and operated by the project, but the local jurisdiction specifies that they must meet certain criteria, the materials may not be excluded from the calculations.

LEED Interpretation
Inquiry:
Would aggregate and chat covered areas be considered hardscape or a non-hardscape, pervious paving type surface? If the aggregate and chat are considered hardscape, what SRI values should be used, or how is the SRI value for these materials determined? If no industry standard is available, is it permissible to compare the aggregate/chat to a material with a known SRI value? Or could we use the value from a comparable color on the Munsell Color Code (or similar)?
Ruling:
Aggregate and chat areas must be considered hardscape, and would not count as open-grid pavement systems, for the purposes of this credit. To determine the SRI for materials that do not have recognized standard values (e.g. new gray concrete), the materials must be individually tested (per LEED NC v2.1 CIR Ruling dated 6/27/2003). As stated in the credit description, it is necessary to provide the documentation indicating the solar reflectance index of the aggregate/chat as meeting the requirement. It is not acceptable to compare materials used on the project to a material with a known SRI value. Color values do not have direct correlation to emissivity and solar reflectance values which are the basis for the SRI calculation. Aggregate may be tested using ASTM E1918-06 (Solar Reflectance) and ASTM E408-71(2008) (Thermal Emittance) and then the SRI may be calculated using ASTM E1980. Applicable internationally.
