LEED for Homes Mid-Rise 2010 Verification & Guidelines For Verification Teams These guidelines summarize the verification and submittal requirements for LEED for Homes Mid-Rise. Roles and Responsibilities: One of the core strengths of the LEED for Homes program is that the green components are all verified by a third-party. Third-party verification is essential the integrity of the program, as it gives prospective home buyers confidence and reassurance. These verification and submittal guidelines are for Green Raters, who deliver verification services under the direct supervision of a LEED for Homes Provider. Although verification is primarily performed by a third-party team (i.e., the Green Rater and Provider), the project team plays a critical role. A separate set of verification and submittal guidance is available for project teams (in a companion document). Key stakeholders in the LEED for Homes program each have unique roles in the delivery of verification services LEED for Homes projects, including: Provider QAD Review and approve all work performed by Green Rater Make final decisions on all verification tasks Green Rater / qualified energy rater Complete all in-field verification steps Complete all performance tests Complete LEED for Homes Project checklist Review documentation and submittals from project team Compile all additional info needed for certification from project team Project Team Notify LEED for Homes Provider and/or Green Rater when project is ready for verification, Complete all accountability forms, the durability risk evaluation form, and the durability inspection checklist, and Provide the information described below the Green Rater, and any additional information requested by the Green Rater.

Minimum Verification Requirements These verification guidelines represent the minimum verification steps be conducted. Subject input from the Provider Quality Assurance Designee (QAD), Green Raters are allowed discretion in verifying that the Rating System requirements are satisfied, as follows: o Where a measure can be definitively verified using a simpler alternative the guidelines below, that is acceptable; o Where there is doubt or limited confidence in a particular builder or proposed strategy, additional verification steps may be incorporated or supporting verification materials may be collected. In general, Green Raters can verify LEED measures by: 1. On-site observations 2. Reviewing the work of other third-party verifiers (e.g. qualified energy raters), and 3. Reviewing supporting verification materials provided by the project team (such as, documents with calculations, manufacturers cut sheets, product packaging, etc.). Supporting Verification Materials Although some elements of a green home can be easily verified through simple observation, many of the specific LEED for Homes requirements are difficult verify without additional information product specifications, contracr calculations, etc. The term supporting verification materials refers the additional information that Green Raters may need in order fully verify that the home has met the criteria for LEED certification. Supporting verification materials are not formal submittals, and no outside consultant should be needed assist with the compilation of these materials. Also, except where noted in the guidelines below, the verification team is not expected collect copies of supporting verification materials from the project team. will not collect or review supporting verification materials during any audits. If the Provider QAD wants collect supporting verification materials assist in the training and oversight of Green Raters, he/she may do so. Recommended rates for the collection of supporting verification materials are shown in the table below. Liability and Verification of Workmanship US Green Building Council - 2 - Ocber, 2010
The project team is solely responsible for the selection, design, and installation of all elements of the building. The verification team is responsible only for verifying the completion of LEED for Homes requirements as set forth in the LEED for Homes Rating System; such verification in no way constitutes a warranty as the appropriateness of the selected LEED for Homes measures or the quality of implementation. The purpose of the verification processes in LEED for Homes is verify that the selected LEED measures are in fact physically installed in the building. As part of the verification, the LEED for Homes Providers and their Green Raters should not attempt assess whether the LEED measures are designed or installed properly, or assess the overall quality of workmanship. LEED for Homes Providers and their Green Raters are strongly advised proactively protect themselves from potential liability. When verifying calculations, the Green Rater should only verify that the calculations were done using the appropriate ols, except where noted in the guidelines below. The Green Rater should not double-check the accuracy of the calculations. If clearly obvious mistakes are observed by the Green Rater, these can be cause for a re-submittal of the calculations by the project team. Accountability Forms There are various LEED for Homes requirements especially those that include a significant design element or rely on professional expertise that cannot be fully verified by a Green Rater through observation, even with supporting verification materials. For these measures, an Accountability Form is required. An Accountability Form is signed by the responsible party (e.g. HVAC engineer, landscape professional, PV installer) indicate that all elements of the prerequisite or credit have been met. Accountability Forms should be signed after installation or construction of the relevant measure. Fewer than one-third of the prerequisites and credits in LEED for Homes require an Accountability Form, and they are all identified below. Pho-documentation Subject the discretion of the Provider QAD and Green Rater and the guidelines put forth in the Green Rater Manual, pho-documentation may be used as a substitute for on-site verification. Energy Performance Tests Performance tests in the EA category must be conducted by a qualified energy rater, or -approved alternative. The energy rater and the Green Rater may be the same person, but it is not required. US Green Building Council - 3 - Ocber, 2010
