Energy Star Most Efficient Criteria Released

July 30th, 2018 by Editor

The U.S. Environmental Protection Agency (EPA) has released the proposed recognition criteria for 2019’s Energy Star Most Efficient products, including windows.

As of July 2018, 419 window product lines are recognized as Most Efficient from more than 40 product brand owners, according to the EPA. In all, 2,899 models from 155 Energy Star partners that span products ranging from boilers to HVAC equipment and appliances meet the 2018 Most Efficient recognition criteria.

The agency says only windows for residential buildings are eligible for Most Efficient recognition. Commercial windows, doors, skylights and tubular daylighting devices are excluded.

According to the EPA, the window must be “Energy Star certified consistent with applicable Energy Star Partner Commitments and the requirements set forth in the latest version of the Energy Star Program Requirements and Eligibility Criteria for Windows.”

Additionally, products must be independently certified to meet the North American Fenestration Standard/Specification (NAFS) with a Performance Grade of 15 or higher. They must also have a U-factor of 0.20 or lower in all climate zones, plus a solar heat gain coefficient (SHGC) of  0.20  or higher in the Northern climate zone; a SHGC of 0.40 or lower in the North-Central zone; and a SHGC of 0.25 or lower in the South-Central and Southern zones.

EPA will hold a stakeholder webinar on September 11, 2018 from noon to 2 p.m. ET to discuss the proposed 201 9 recognition criteria. To participate in this webinar, follow this link to register by September 10. Please send written comments no later than September 5, 2018 to EPA plans to finalize these recognition requirements in September
