Tests will be conducting in qualified laboratories using AHRI, ASHRAE and/or ANSI standards Do need to conduct tests at off AHRI conditions which includes economizers and faults. Follow AHRAE/ANSI instrumentation protocols and applicable. Test conditions per test plan. Permit/Compliance Market Assessment Obtain permit data for participants and installations Obtain total permit counts and permit/compliance costs. Using QM sites for permitting has issues since they are existing systems. Permitting rate only requires counts of non-participant units with permits, while compliance requires more detailed file review and onsite inspections. The performance of systems that are close to compliance is also different than those with duct leakage, sizing, and airflow far from the standard Site surveys for non-participants only as they will serve as a baseline for both QI and To Code. QM participants should be excluded. Market Actor interviews should include: HERS Raters, Code Officials (part of permit data collection), CSLB, Contractors, Distributors, CEC Code setting staff. The IOU Market Assessment may be a good gateway survey of customers to identify non-participants and then offer a follow-up onsite. • Conduct site surveys at a sample of QI/QM program participants and non-participants (permitted/unpermitted, if available) to obtain T24 compliance baseline estimate and collect data related to HVAC Market Transformation Indicators. • Study how effectively HVAC replacements, including emergency replacements, are complying with permitting obligations under SB 454 and directed in the Guidance Decision 09-11-014. • Conduct phone interviews with market actors.
