NREL Celebrates Industry Advancements on Weatherization Day

Key Resources Are Helping the Weatherization Workforce Provide Benefits for Low-Income Households

The perfect winter coat should be comfortable to wear-not too warm and not too cold. It's affordable, sturdy, and protects you well from the wind, rain, and snow.

The U.S. Department of Energy's (DOE's) Weatherization Assistance Program (WAP) helps thousands of low-income families find the perfect coat for their homes every year. Installations and upgrades through weatherization services work to increase the energy efficiency and safety of homes-ensuring that they can stay comfortable through the changing seasons, with lower energy bills and health benefits for residents.

The National Renewable Energy Laboratory (NREL) supports WAP in strengthening the weatherization and home performance industry through robust, collaborative resources for building up a qualified workforce and quality work.

This Weatherization Day, NREL is celebrating its work on key resources developed over the past year to highlight and advance WAP's impact across states and territories.

Telling the Story of Weatherization

As weatherization enhances homes through upgrades, it changes lives.

One homeowner in Utah was paying energy bills that were higher than her house payments. Once WAP worked on her home, not only were her bills reduced, but potential safety issues in her home were also addressed. "It's a game changer," the homeowner said.

NREL is working to compile stories like these in WAP's Successes & Solutions Center, a database of short examples that WAP organizations can use to improve their own processes and celebrate positive impacts for clients. Stories include successes in workforce development, technical solutions, and more.

"There are so many innovative processes that WAP agencies across the country use every day, but not everybody knows about them," NREL researcher Allison Moe said. "By highlighting these solutions, we aim to give the weatherization network more insight into new methods they can try out in their work."

These examples provide useful details for replicable solutions-and photos can be just as helpful for inspiring better processes. Maintained by NREL, DOE's Weatherization Image Gallery is a free-to-use resource with over 150 high-quality images. The gallery contains images of weatherization installations, mechanical equipment, and materials. These photos are vetted by NREL researchers for accuracy and compliance with the Standard Work Specifications, an industry guide to ensure home energy upgrade work is effective, durable, and safe. WAP organizations can use these images to enhance their field guides, presentations, marketing materials, and more to help visualize the impact of weatherization.

Supporting Weatherization Workers in the Field

Residential energy auditors are always on the go, providing in-depth house assessments and developing comprehensive scopes of work for upgrades needed in client's homes. NREL's Residential Energy Auditor Resource Repository gathers useful resources into one place for energy auditors in the field, so they can save time searching for the online tools needed to complete their assessments.

As part of this effort, NREL supported a makeover of DOE's Refrigerator and Freezer Energy Rating Search Tool. With a variety of brands, model numbers, and manufacture years to search by, the tool allows energy auditors to quickly discover the energy consumption for these appliances in client's homes.

"During a comprehensive energy audit, the accuracy of an energy auditor's assessment is key," said Cory Chovanec, NREL weatherization colead. "This resource repository aims to help energy auditors locate accurate information more quickly in support of data collection or analysis of residential buildings."

This summer, NREL began work with the Association of Energy Engineers on another effort to support a qualified workforce: a virtual field exam. Historically, aspiring energy auditors must pass an online written exam and in-person field exam at an approved field-test site. By adding a simulated exam as an option, energy auditors will have more flexibility in pursuing their certification.

"Accessibility is important to support growing a diverse and equitable weatherization workforce," NREL researcher Meredith Cummings said. "Introducing a simulated field exam provides trainees with a potentially more convenient option if needed."

A pilot of the new simulated field exam is expected to launch in 2026.

Paving the Way for Technical Advances

In 2022, DOE issued guidance streamlining the inclusion of solar photovoltaics in weatherization services for clients. The number of local and state WAP programs utilizing solar is growing, and NREL research is helping these programs determine which solar pathways are right for them.

NREL developed a technical report, an online decision guide, and case studies to help programs make informed decisions about how to integrate solar into their work. These resources assist agencies with developing a plan for solar that works best for their service area. Solar technologies might include rooftop solar, community solar, or solar water heaters.

"WAP implementers can be key contributors in broadening solar energy access for low-income households," said Juliana Williams, NREL weatherization colead. "These resources can help them maximize benefits for clients."

NREL also contributed to a new toolkit with relevant guidance for installing heat pumps in homes. DOE's Cold Climate Air Source Heat Pump Toolkit provides technology information, consumer information, weatherization and efficiency program partner resources, guidelines and training for contractors, and ongoing technology development and case studies.
