What training and certification do HERS raters undergo?
HERS raters are typically experienced building professionals, who in addition take a week or two week long intensive training course in residential energy efficiency. After completing the training, learning how to use HERS rating software, and passing a test9, new raters must also complete at least 5 ratings with an experienced HERS rater before being able to independently award ratings. In addition to this initial training and certification, HERS raters must be affiliated with a certified HERS provider which is responsible for ongoing code education and quality assurance oversight of the HERS rater’s work. The HERS providers also carry liability insurance and allow builders to request a review from a second HERS rater in the rare case of disputes.
