The 2009 Seattle Energy Code (and Washington State Energy Code), Section 1411.1, last sentence of the first paragraph, requires that products covered under Tables 14-1A through 14-1G be listed in a nationally recognized certification program. Tables 14-1A(3) and 14-1A(4) specify minimum equipment efficiencies for VRF equipment and cite AHRI Standard 1230 as the test procedure.
- Per AHRI, the AHRI certification program for variable refrigerant flow (VRF) equipment is now underway for products covered under AHRI Standard 1230.
- Consequently, permit applications that include VRF equipment need to demonstrate that the VRF equipment has AHRI certification (e.g. VRF equipment efficiency needs to be determined in accordance with AHRI Standard 1230 and certified in the AHRI Certification Program, etc.).
