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 (21 V.S.A. § 267 (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") was approved and adopted on May 22, 2003 with an effective date of July 1, 2003. The purpose of this Procedure is to ensure that accurate and consistent home energy ratings are performed by accredited HERS providers. It will promote an objective, cost-effective, and sustainable home energy rating process 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.


The complete accreditation package contains four documents. Providers seeking accreditation need only submit the application, but are strongly recommended to review all of the documents. The documents are available in Portable Document Format (PDF). This format allows documents to appear and print the same across different computer operating systems.
