Ever since the launch of Version 3 in 2010, the HVAC design and commissioning requirements have been the biggest hurdle between a standard HERS rating and an ENERGY STAR certified home. Taking all the lessons learned, EPA, RESNET, and ACCA are finishing work on a new HVAC grading standard that will integrate many of these requirements into the HERS rating process. This webinar, presented on August 26, 2020, provides an overview of the standard, how it will be integrated into the ENERGY STAR program, and a status update on when it can be used. Contact the ENERGY STAR team to receive a recorded copy of the webinar.
To earn the ENERGY STAR, a home must be certified under Version 3 of the program requirements, unless it is located within a U.S. state or territory utilizing a regional specification. Working with a Home Energy Rater, builders configure the preferred set of energy measures for their home and verify that the resulting Energy Rating Index meets or exceeds the ENERGY STAR Energy Rating Index Target. The National Program Requirements contain more information about how the target is defined and the typical measures used to meet this target.
For a home to be ENERGY STAR certified, several key commissioning tasks must be completed by a credentialed HVAC contractor. These requirements are contained in the HVAC Commissioning Checklist, and include checking the refrigerant charge, measuring the HVAC fan airflow, and a recommendation to test and balance the room-by-room airflows. Visit our HVAC Resources web page to watch short "how to" videos to help you complete these tasks. Visit the ENERGY STAR Certified Homes Program Requirements page to download the HVAC Commissioning Checklist and visit the ENERGY STAR Certified Homes Policy Changes and Clarifications page to learn more about recent program changes.
For homes located in some U.S. states and territories, ENERGY STAR has developed region-specific Version 3 program requirements. This document defines the core efficiency specifications under Version 3 of the program for ENERGY STAR certified homes located in Guam, Hawaii, Puerto Rico, Northern Mariana Islands, and the U.S. Virgin Islands.
