HERS Verification
San Diego and Riverside County

The HERS verification is a signed document that can only be received from a third-party HERS Rater. This document should be provided after all visual inspections, testing has been performed, and the Rater can verify the minimum CEC requirements have been met. As mentioned before, there are a set of tests that may be conducted during the HERS Verification process.

These tests and how they are applied will be determined by the project scope and climate zone. Standard HERS, also known as residential alterations, is most common, and it is the installation that triggers what HERS Verification is required. Typically, you will see what is called Duct Test or duct leakage verification in most applications that require any portion of the HVAC system to be changed out. The Duct Test is used to measure the airtightness of the duct system, and to verify all possible leakage has been sealed. There are 16 climate zones in California.

Homes located in climate zones two, or 8-15, you may see a Refrigerant Charge Airflow Verification (RCA), and a Cooling Coil Airflow verification (CCA). These Verifications will be triggered in these climate ¬¬zones by having a cooling component of the HVAC system replacement. The CCA and RCA Verifications must run together. This to verify the system is charged correctly, and there is enough airflow, so the system can maintain building comfort as well as the longevity of the equipment. If in any climate zone, the HVAC system is 100% accessible and has been entirely replaced, the CCA verification will be applied along with what's called a fan watt verification (FWD). These two HERS Verifications are also run together. The CCA is the same as before, but the FWD ensures the system is drawing as minimal energy possible. Projects that have what's called a Title 24 Report have been creating by an energy calculations program that establishes the scope of work.

Not only does the Title 24 Report mandate what HERS Verifications are required, but it may also determine what mechanical equipment shall be installed. Although the Title 24 report is typically used for newly constructed buildings, you may see the description used in additions, renovations, and remodels. The already mentioned HERS Verifications are commonly used in the Title 24 Report, but other verifications may be required. Indoor Air Quality Verification (IAQ) is almost always required for newly constructed homes, or homes that have an addition of 1000 square feet or more. The IAQ is applied to measure the home's mechanical ventilation system to verify that proper air quality can be maintained throughout the day. Quality insulation installation verification (QII) is a measure used to make sure that the building envelope is properly sealed and insulated. QII HERS Verification must be done in the framing stage before the drywall and after the insulation has been installed. This is just a visual verification, so no testing would be required. The fenestration verification or Windows verification is also applied visually. The HERS Rater will need access to the data sticker that comes with the windows during installation. Plumbing verification is also visually verified. The HERS Raters will need access to all Plumbing to check if the insulation wrap meets the Title 24 requirement.
