Winners of the U.S. Department of Energy (DOE) Solar Decathlon® were announced! Solar Decathlon, celebrating its 20th anniversary, is DOE's longest-tenured student competition and has challenged 40,000 students across the world to use the latest technologies to design and build the most sustainable buildings possible.

Georgia Institute of Technology and The University of Arizona won this year's Design Challenge for residential and commercial building grand prizes, respectively.

"For 20 years, DOE's Solar Decathlon has harnessed the ingenuity and enthusiasm of America's students to generate cutting-edge climate solutions," U.S. Secretary of Energy Jennifer M. Granholm said. "The innovative building designs developed by this year's competitors demonstrate how clean energy technologies can be applied to households across the country, including slashing costs for American families, modernizing energy infrastructure, and decarbonizing the building sector."

Additionally, 14 Build Challenge teams each earned $50,000 in prize funding to build and exhibit their ground-breaking, zero energy buildings in their home communities next spring, where they will compete for contest and grand prizes in April 2023. Seven more Build Challenge teams are still in the running for the $50,000 in funding and will have the next two months to perfect their designs and resubmit to the competition.

Fifty-four Design Challenge finalist teams from 37 collegiate institutions showcased their high-performance, low-carbon building designs in one of six divisions at the Solar Decathlon Competition Event, held April 22–24, 2022, at the National Renewable Energy Laboratory in Golden, Colorado. Winners include:

  • The Georgia Institute of Technology team—Residential Grand Winner for their design to retrofit a neglected, 102-year-old house in the English Avenue neighborhood of Atlanta, Georgia. The students turned it into a net-positive structure built with materials that naturally absorb carbon. The team also placed first in the Retrofit Division, a new division for the 2022 Design Challenge.
  • The University of Arizona team—Commercial Grand Winner for their multifamily building design that serves low-income and multigenerational families. It integrated hundreds of organic photovoltaic panels, using them to shade a 490,000 square-foot, mixed-use building while keeping accessibility in mind.

The University of Arizona team earned the Commercial Grand Winner Award for their design of a 490,000 square-foot, multifamily building that serves low-income and multigenerational families.

Other competitors were also recognized for designing exceptional buildings of different types, winning first, second, and third-place awards for new construction, retrofits, attached housing, multifamily housing, office buildings, and schools. See the full list of this year's Solar Decathlon winners.

Over 40,000 students around the world have worked together to build homes, careers, and even families through DOE's Solar Decathlon. The competition's hands-on experience provides the skills, experience, and credentials young professionals need to thrive in energy efficiency jobs and fulfill the home-performance industry's top need: more qualified workers.
