A CF-3R refers to a certificate of HERS (Home Energy Rating System) test results. These certificate are created by a HERS Rater, an independent inspector specially-trained by CalCERTS.
The goal of the registry is to provide a place for HERS Raters to submit their test results in comparison with installation (CF-2R) and design (CF-1R) documents. With all the documents in one place, the building department can easily review the digital reports and determine the status of your job.
CF-3R forms are generated when a HERS-verified CF-2R form is submitted. HERS-verified CF-2Rs include forms like the CF-2R MCH-20, ENV-21, 22, and 23, and the PLB-22. Essentially all CF-2R-MCH (mechanical) forms which express the HVAC (Home Ventilation and Air Conditioning) system will have complementary CF-3R forms.
Who Does The CF-3R?
Anyone can be the Documentation Author of a CF-3R form, but only the Rater who performed the tests may be indicated as the Responsible Rater. The HERS Rater must also be certified to take and submit test results for the particular project type. A HERS Rater may view their certifications on their My Transcript page. Anyone can view the certifications of a particular company on the Find A Rater page.
CF-3R forms may only be untested by the HERS Rater who submitted them or by the company controlling the project.
When at least one CF-3R form is submitted for a particular address, a $24 charge is generated ($20 for multi-family per door) to support Quality Assurance fees. This fee is generally paid for by the Rater.
CF-3R-EXC-20: Verification of Existing Conditions
In a Performance-based CF-1R, your energy consultant can indicate for existing conditions to be verified by a HERS Rater. By doing this, it provides your compliance file additional compliance percentage - your compliance file must be over 0% compliance rating, with 0% being the minimum-allowable energy efficiency.
If you do not want to do an EXC-20 test, you'll need to remodel your calculation file to not include verification of existing conditions.
