Certificates of Installation are required for all buildings and shall include the required compliance information for all of the installed space conditioning systems in the building that must comply. When compliance requires HERS verification, the builder’s employees or subcontractors shall perform diagnostic testing according to the procedures specified in Reference Nonresidential Appendix NA2, and verify that the measures meet the requirements for compliance 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.
A signed copy of the Certificate of Installation shall be posted at the job site for review by the enforcement agency, in conjunction with requests for final inspection. Alternatively, contingent upon approval of a Nonresidential Data registry, the enforcement agency may elect to view the certificates on an approved Data Registry. A copy shall be provided to the HERS Rater. .
When the Standards do not require the Certificate of Installation to be registered, the Certificates of Installation that are posted in the field for review by the enforcement agency at final inspection are not required to be registered certificates from a Data Registry, but shall conform to all other applicable requirements of 10-103(a)3.
