When HERS field verification and diagnostic testing is required to be performed in accordance with NA1 and NA2 procedures, compliance with HERS verification may alternatively be satisfied by a certified Acceptance Test Technician (ATT) according to the requirements specified in this section.
Under this alternative procedure, when the Certificate of Compliance indicates that HERS field verification and diagnostic testing is required as a condition for compliance with Title 24, Part 6, a certified ATT may perform the verification to satisfy the condition of compliance, at the discretion of the enforcement agency. Systems verified under this procedure are not eligible for use of the sampling procedures described in NA1.6.
The ATT shall perform the required field verification and diagnostic testing according to the procedures specified in Reference Nonresidential Appendix NA2, and verify that the work meets the requirements for compliance as shown on the Certificate of Compliance. The owner or installer shall complete a Certificate of Installation and sign the certificate to certify that the installation work meets the requirements for compliance credit.
The ATT shall sign a copy of the Certificate of Acceptance and submit a copy to the approved ATTCP. The acceptance procedures for the Certificate of Acceptance shall conform to the requirements in NA1.5.
A signed copy of the Certificate of Acceptance shall be posted at the job site for review by the enforcement agency, in conjunction with requests for final inspection in accordance with NA1.3.4.
The Certificate of Acceptance that is posted in the field for review by the enforcement agency at final inspection shall conform to all applicable requirements of 10-103(a)4.
