A Home Energy Rating System (HERS) is a process of administering diagnostic analysis to determine and produce data that provides a method of evaluation for a California State approved home energy efficiency ratings. This establishes a benchmark of a home’s energy use and identifies necessary and/or best possible upgrades for homeowners.

In 2003 CalCERTS, Inc. was approved by the California Energy Commission to become a Home Energy Rating System (HERS) Provider. The company’s mission is to fill the growing need in the Energy Efficiency industry for a technically superior, yet customer-oriented HERS Provider. CalCERTS, Inc. is a private organization that provides service, support, training and certification to HERS raters.

HERS raters are independent contractors who are either independently operated or who sub-contract to larger energy rating firms. Raters charge their customers for site ratings and pay a fee to CalCERTS, Inc. for processing the ratings and issuing certification.

CalCERTS, Inc. has developed and owns its own software which is approved by the California Energy Commission and is utilized by the HERS rater to enter rating data. CalCERTS, Inc. maintains the computer based registry of data as a repository of information that can be accessed by the HERS rater, building departments, contractors and government agencies.
