What is a HERS rating?

PEC is a certified HERS rater supplying property managers and commercial proprietors with Home Energy Rating System (HERS) services for new construction and existing construction. To comply with state guidelines, HERS ratings and verifications must be performed by a neutral, third-party energy rating company that understands Title 24 standards. HERS verifications are mandatory in order to close out permits for most types of energy upgrades. 

To verify that a facility’s energy upgrades meet IA energy requirements, Preferred Energy Consultants HERS raters conduct field inspections and diagnostic testing of your building’s energy performance and mechanical equipment. Working directly with commercial property managers and facility owners or alongside their contractors, we provide commercial HERS testing for office buildings, small businesses, large-scale facilities, and other commercial environments.

Results of these tests, along with inputs derived from the plan review, are used to generate the HERS Index score for the business
