Before such programs may be used to demonstrate compliance with the standards, they must be approved by the Energy Commission through the process described in the Manual. The Residential ACM Manual in Chapter 7 also contains requirements for field verification and diagnostic testing when compliance credit is contingent on field verification and diagnostic testing. The appendices to the Residential ACM Manual contain the protocols that must be followed by contractors and HERS raters for completing field verification and diagnostic testing when required.
