Whole-house mechanical ventilation plays a critical role in the ENERGY STAR Single-Family New Homes program. It helps ensure that efficiency is not achieved by sacrificing indoor air quality. Delivering an effective system is a three-step process that involves the HVAC designer, the HVAC contractor or electrician, and the Rater. This technical bulletin is designed to reinforce the responsibilities of each party with regards to the whole-house ventilation airflow rate.
Watch this webinar, presented on December 5, 2018, to learn about efforts from EPA and RESNET to reward proper design and installation of HVAC systems with HERS points. This will include an overview of where EPA and RESNET are in the process of developing a new standard, tests that may be required, and potential HERS impact. Contact the ENERGY STAR team to receive a recorded copy of the webinar.
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.
HVAC grading is here! Watch this webinar, presented on November 5, 2020, to learn how the new ACCA/RESNET standard for grading HVAC design and installation integrates with ENERGY STAR, offers new opportunities for ERI points, streamlines the certification process, and provides an opportunity to bring builders back to the program. Contact the ENERGY STAR team to receive a recorded copy of the webinar.
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.
