Appendix NA1 provides direction for communication and documentation processes that must be completed for compliance with the verification requirements for multifamily dwelling units (dwelling units) that require field verification and diagnostic testing by an ECC-Rater, using the testing procedures in Reference Nonresidential Appendix NA2. The Commission approves ECC-Providers, subject to the Commission’s program regulations, which appear in Title 24, Part 1, Section 10-103.3. Approved ECC-Providers are authorized to certify ECC-Raters and maintain quality control over field verification and diagnostic testing.
When the Certificate of Compliance indicates that field verification and diagnostic testing of specific energy efficiency measures are required as a condition for compliance with Title 24, Part 6, an approved ECC-Provider and certified ECC-Rater shall be used to conduct the field verification and diagnostic testing according to the applicable procedures in Reference Nonresidential Appendix NA2. As specified by Title 24, Part 1, Section 10-103.3, ECC-Providers and ECC-Raters shall be independent entities from the builder or subcontractor installer of the energy efficiency improvements being field verified or diagnostically tested. An “Independent Entity means having no financial interest in, and not advocating or recommending the use of any product or service as a means of gaining increased business with, firms or persons specified in Title 24, Part 1, Section 10-103.3. Third Party Quality Control Programs approved by the Commission may serve some of the functions of ECC-Raters for field verification and diagnostic testing purposes as specified in NA1.7. Also, Acceptance Test Technicians may serve the function of an ECC-Rater for field verification and diagnostic testing purposes as specified in NA1.9.
The remainder of Reference Nonresidential Appendix NA1 describes the:
- Requirements for documentation and communication for verification compliance processes;
- Responsibilities assigned to each of the parties involved in the field verification and diagnostic testing process;
- Requirements for procedures for installing contractors and Certificate of Installation documentation;
- Requirements for ECC-Rater field verification and diagnostic testing and documentation procedures;
- Requirements for sampling procedures for verification compliance;
- Requirements for Third Party Quality Control Programs;
- Requirements for verification compliance for alterations to existing buildings.
Table NA1-1 describes the measures that require installer certification and ECC-Rater field verification and diagnostic testing and identifies the protocol or test procedure in the Reference Nonresidential Appendices that shall be used for completing installer and ECC-Rater field verification and diagnostic testing.
