hvac hers ratings and verifications

As HERS raters and BPI-certified energy inspectors, We Green offers Home Energy Rating System (HERS) services for contractors and builders requiring a neutral, third-party energy rating. HERS testing and verifications are required in order to comply with Title 24 California energy code standards. These tests must be conducted on most energy upgrades, alterations, new homes, home additions and remodels, and most commercial buildings.
To verify the energy-efficiency of a property, our HERS raters conduct field inspections and diagnostic testing of the building’s energy components as well as operational performance. The HERS rating process may include a variety of diagnostic tests, field verifications, and energy assessments. During their visit, our HERS raters may evaluate the energy efficiency of:
  • Heating & cooling systems
  • Ventilation systems
  • Supply & return ductwork
  • Building envelopes
  • Building components such as lighting, insulation, water heating, windows & doors
  • Domestic hot water heating systems
After conducting required field inspections, our team processes all completion documents, certifications, and state energy code compliance requirements so you can pass necessary building inspections.


In addition to ensuring compliance with the latest California Title 24 building code standards, We Green’s independent, third-party HERS rating process offers a number of proven benefits for our client partners. Most of all, we serve as an extension of your business: interfacing professionally and seamlessly with your team and your customers.
