HERS Provider Accreditation Procedure


In 1997, the Vermont Legislature adopted the Residential Building Energy Standards (RBES), mandated an update process, and required the Department of Public Service (PSD) to implement an accreditation procedure for Home Energy Rating Systems (HERS) providers (30 V.S.A. § 52 (a)). The accreditation procedure is the result of several years work building consensus among affected stakeholders, including rating providers, builders, lenders, real estate professionals, and consumer representatives.

The PSD HERS Accreditation Procedure ("Procedure"), originally approved and adopted on May 22, 2003, was updated in 2021 with an effective date of October 29, 2021. The purpose of HERS Accreditation is to ensure that accurate and consistent home energy ratings are performed by qualified HERS energy raters providing Vermonters with objective, cost-effective, and sustainable home energy rating services which can do the following:

  • Serve as compliance method for residential building energy codes;
  • Accurately gauge the performance of energy saving measures;
  • Help Vermont's housing market reliably differentiate products based on energy efficiency.

The Procedure sets minimum standards for rater training, operating procedures and policies, software programs, and quality control. These standards assure that customers can rely on the representations of accredited providers.
