HERS

HERS (HOME ENERGY RATING SYSTEM) ENERGY MODELING

The HERS index rates each home on a scale where 0 is a zero-net-energy home , and 100 is a home built to the 2006 base energy code. HERS ratings are performed by HERS raters- independent certified building energy professionals.

The HERS rating involves a detailed energy model of the home, inspections, and diagnostic testing. It is an asset rating, meaning that all fixed elements to the home are factored including thermal boundary details, mechanical systems, ventilation systems, some appliances, renewable energy systems, and lighting fixtures.

For code compliance, the final index (score) is submitted to the local building official during plan review. A good HERS rater will be a resource to the building team through the design and construction processes.
