HERS Update to Standard ANSI/RESNET/ICC 301-2019 MINHERS Addendum 42 adopted Standard ANSI/RESNET/ICC 301-2019 to replace Standard ANSI/RESNET/ICC 301-2014 as the basis for calculation of the HERS rating. Addendum 42 currently allows voluntary use of RESNET accredited software based on Standard 301-2019 and has established a “Mandatory Compliance Date” of January 1, 2022. See Section 502.3.2 for the definition “Mandatory Compliance Date” and how it applies to your Rating. Furthermore, for any Rating using Standard 301-2019, the RESNET Guidelines for Multifamily Energy Ratings may no longer be used. 101 General Provisions Updated on 28 Jun 2022 101.1 Purpose The purpose of these Standards is to ensure that accurate and consistent home energy ratings are assured by RESNET accredited Rating Quality Assurance Providers (Provider) through their Certified HERS Raters nationwide; to increase the credibility of the Rating Quality Assurance Providers and to promote voluntary participation in an objective, cost-effective, sustainable home energy rating process. Leaders in both the public and private sectors have identified the need for an accreditation process for Rating Quality Assurance Providers. This accreditation process may be used by these stakeholders to accept home energy ratings and to assure accurate, independent information upon which the mortgage industry may accept home energy ratings for the purposes of issuing energy efficient mortgage, or similar, products; a state may recognize the home energy ratings as a compliance method for state building energy codes; as qualification for public and private sector energy programs designed to reach specific energy saving goals; and as a way to provide housing markets the ability to differentiate residences based on their estimated energy efficiency. These Standards have been developed to satisfy the above purposes. 101.1.1 Relationship to State Law These Standards specifically recognize the authority of states that have laws requiring certification or licensing of Rating Quality Assurance Providers. To the extent that state laws differ from these Standards, state laws shall govern. 102 Accreditation Criteria for Rating Quality Assurance Providers Updated on 05 Jul 2022 102.1 Rating Quality Assurance Provider Responsibilities All accredited Rating Quality Assurance Providers shall have the following minimum responsibilities: 102.1.1 Perform sufficient quality assurance oversight of HERS Raters, Rating Field Inspectors (RFI) and HERS Modelers to ensure compliance with these Standards and the minimum quality assurance requirements outlined in Chapter 9.
