California Energy Commission Letterhead
 

To: California building departments, contractors, HERS raters, and other interested parties.

This is to inform you that the California Energy Commission has approved two Home Energy Rating System (HERS) Providers to perform field verification and diagnostic testing for the 2008 Building Energy Efficiency Standards, effective January 1, 2010. The two approved HERS Providers include California Certified Energy Rating and Testing Services (CalCERTS) and California Home Energy Efficiency Rating Services (CHEERS).

The California Energy Commission is currently reviewing the HERS Provider application submitted by California Building Performance Contractors Association (CBPCA) to perform field verification and diagnostic testing for the 2008 Building Energy Efficiency Standards, but the application has yet to be approved. As such, no HERS raters operating solely under CBPCA are approved under the 2008 Building Energy Efficiency Standards.

In addition to applying as a HERS Provider, CBPCA has requested that Enalasys be approved as a Third-Party Quality Control Program. The approval of Enalasys as a Third-Party Quality Control Program for the 2008 Building Energy Efficiency Standards is dependent on CBPCA's approval as a HERS Provider, so Enalasys will not qualify for approval until CBPCA is approved for the 2008 Building Energy Efficiency Standards.

Until approval of CBPCA as a HERS Provider and Enalasys as a Third-Party Quality Control Program, only sample groups of up to seven homes (or HVAC systems, etc.) will be allowed for HERS measure verification of new installations and change-outs. You will receive notice if and when sample groups of up to 30 homes (or HVAC systems, etc.) will be allowed upon approval of Enalasys as a Third-Party Quality Control Program.

To summarize:

  • only CalCERTS and CHEERS HERS providers and their respective raters are approved under the 2008 Building Energy Efficiency Standards;
  • neither CBPCA as a HERS provider or CBPCA HERS raters are currently approved under the 2008 Building Energy Efficiency Standards;
  • Enalasys equipment may be used for the initial testing of sample groups of up to seven (7), but not for sample groups of up to thirty (30).
