Part B, a continuation of Part A, will provide addition information on the ENERGY STAR 3.0: Thermal Enclosure System Rater Checklist. All homes permitted after January 1, 2012 seeking ENERGY STAR Version 3.0 rating must meet ENERGY STAR Version 3.0 standards. Verification partners, including HERS raters and Field Inspectors, must complete ENERGY STAR Version 3 Rater Training through an Accredited Training Provider in order to service and/or inspect homes that seek ENERGY STAR Version 3.0 rating. There are two paths to certify a home to earn the ENERGY STAR. The Prescriptive Path is based on a predefined package of improvements, while the Performance Path is based on a customized package of upgrades. The National Program Requirements define the core energy efficiency specifications for both the Prescriptive and Performance Paths.
