[Pursuant to the UCC, delete Section R406.7.2 and replace as follows:]
EC- R406.7.2 (N1106.7.2) Compliance report. Compliance software tools shall generate a report that documents that the home and the ERI score of the rated design complies with Sections R406.2, R406.3 and R406.4. Compliance documentation shall be created for the proposed design and shall be submitted with the application for the building permit. Confirmed compliance documents of the built dwelling shall be created and submitted to the code official for review before a certificate is issued. Compliance reports shall include information in accordance with Sections R406.7.2.1 and R406.7.2.2.
EC-R406.7.2.1 (N1106.7.2.1) Proposed compliance report for permit application. Compliance reports submitted with the application for a building permit shall include the following:
1. Building Street address or other building site identification
2. Declare ERI on title page and building plans.
3. The name of the individual performing the analysis and generating the compliance report.
4. The name and version of the compliance software tool.
5. Documentation of all inputs entered into the software used to produce the results for the reference design and/or the rated home.
6. A certificate indicating that the proposed design has an ERI less than or equal to the appropriate score indicated in Table R406.5 when compared to the ERI reference design. The certificate shall document the building component energy specifications that are included in the calculation, including: component level insulation R-values or U-factors; assumed duct and building envelope air leakage testing results; and the type and rated efficiencies of proposed heating, cooling, mechanical ventilation, and service water-hating equipment to be installed. If on-site renewable energy systems will be installed, the certificate shall report the type and production size of the proposed system.
7. When a site-specific report is not generated, the proposed design shall be based on the worst-case orientation and configuration of the rated home.
R406.7.2.2 (N1106.7.2.2) Confirmed compliance report for a certificate of occupancy. A confirmed compliance report submitted for obtaining the certificate of occupancy shall be made site and address specific and include the following:
1. Building street address or other building site identification
2. Declaration of ERI on title page and on building plans
3. The name of the individual performing the analysis and generating the compliance report.
4. The name and version of the compliance software tool.
5. Documentation of all inputs entered into the software used to produce the results for the reference design and/or the rated home.
6. A final confirmed certificate indicating that the confirmed rated design of the built home complies with Sections R406.2 (N1106.2) and R406.4 (N1106.4). The certificate shall report the energy features that were confirmed to be in the home, including: component-level insulation R-values or U-factors; results from any required duct system and building envelope air leakage testing; and the type and rated efficiencies of the heating cooling, mechanical ventilation, and service water-heating equipment installed. Where on-site renewable energy systems have been installed on or in the home, the certificate shall report the type and production size of the installed home.

[Pursuant to the UCC, delete Section R406.7.3 and replace as follows:]
R406.7.3 (N1106.7.3) Renewable energy certificate (REC) documentation. Where on-site renewable energy is included in the calculation of an ERI, one of the following forms of documentation shall be provided to the code official:
1. Substantiation that the RECs associated with the on-site renewable energy are owned by, or retired on behalf of, the homeowner.
2. A contract that conveys to the homeowner the RECs associated with the on-site renewable energy, or conveys to the homeowner an equivalent quantity of RECs associated with other renewable energy.

Pursuant to the UCC, delete Section R406.7.4 and replace as follows:
EC-R406.7.4 (N1106.7.4) Additional documentation. The code official shall be permitted to require the following documents:
1. Documentation of the building component characteristics of the ERI reference design
2. A certification signed by the builder providing the building component characteristics of the rated design.
3. Documentation of the actual values used in the software calculations for the rated design. R406.7.5 (N1106.7.5) R406.7.2 (N1106.7.2) Specific approval. Performance analysis tools meeting the applicable subsections of Section R406 shall be approved. Documentation demonstrating the approval of performance analysis tools in accordance with Section R406.7.1 shall be provided. Tools are permitted to be approved based on meeting a specified threshold for a jurisdiction. The code official shall approve tools for a specified application or limited scope.
