Preparing your windows and doors for Energy Star Version 7.0

One critical date that windows and door manufacturers need to know this year is October 23, 2023: the day that fenestration products need to comply with the new criteria for Energy Star V7.0. Read on to learn more about this important new standard update and what Energy Star V7.0 means for your business.

What is Energy Star V7.0?

Energy Star 7 specification addresses energy performances for Residential Windows, Doors, and Skylights (WDS). The updated criteria will go into effect on October 23, 2023; eligible products are able to receive early certification starting immediately. All current products have until April 23, 2023, to be certified to Energy Star 6.0; after that date, all products must meet the version 7.0 criteria. Depending on their region of installation, the qualifying windows, doors, and skylights, will have to bear a certain degree of heat flow (U-factor) out of the house – lower in the Northern zones while less concerning in Southern zones where focus shifts to solar heat gain coefficients instead.

Doug Anderson, EPA – Program Manager for windows, doors, and skylights, was asked to address key changes regarding the new requirement, where he explained that the EPA’s most significant change is in the subcategory of doors, by making a modest adjustment to the requirement. The change moved the criteria from = 0.25 to = 0.26, allowing a greater number of > ½-Lite doors to qualify.

There were other concerns from stakeholders that the deadline was too soon, and a request was made for a January 2024 deadline. The EPA recognized that most leadership products were already meeting the new criteria, therefore the effective date will remain on October 23, 2023.

What does Energy Star V7.0 mean for manufacturers?

A big selling point for manufacturers will be the projected energy savings to consumers. For a $33 billion dollar industry, sales will rely heavily on a product's certification to the Energy Star requirements. Manufacturers will also consider how their products affect the environment.

Anderson expanded on the benefits to the environment and consumers by suggesting that if all residential windows and doors were certified to meet the new Energy Star requirements, the cost savings could be upwards of $156 billion each year. He also states that the levels of greenhouse gas emissions would decrease by fifty-three billion pounds.
