About the Solar Decathlon  

The U.S. Department of Energy Solar Decathlon® is a collegiate competition that prepares the next generation of building professionals to design and build high-performance, low-carbon buildings powered by renewables. The Design Challenge is a one- to two-semester, design-only competition, while the Build Challenge is a two-year design-build competition.

Celebrating its 20th anniversary in 2022, the Solar Decathlon has challenged more than 25,000 students to create efficient, affordable buildings powered by renewables, while promoting student innovation, STEM education, and workforce development opportunities in the buildings industry.

Buildings account for 75% of electricity use, 40% of total energy use, and 35% of carbon emissions in the United States. Solar Decathlon supports a key strategy for tackling climate challenges: developing a workforce that is equipped to design and construct a low-carbon building stock and deliver an equitable clean energy future.

Additional details are available on the Solar Decathlon website.

Fifty-five teams representing 38 universities are advancing as finalists in the U.S. Department of Energy Solar Decathlon^® 2022 Design Challenge.

Finalist teams were chosen based on presentations and design submissions at the semifinal competition event, held virtually February 25–26, 2022. During this event, teams pitched their unique building designs, impressing industry expert jurors with their creativity and ability to tackle the most difficult issues in the built environment.

It’s the 20^th anniversary of the Solar Decathlon, and 133 teams from 107 collegiate institutions are off to the races as competition begins for the U.S. Department of Energy Solar Decathlon® 2022 Design Challenge and 2023 Build Challenge teams in 20 countries and 29 U.S. states.

Over its lifetime, the Solar Decathlon has challenged more than 25,000 students to create high-performance, efficient, and affordable buildings powered by renewables while promoting student innovation, STEM education, and workforce development opportunities in the buildings industry. The Design and Build Challenges are composed of 10 contests. The Design Challenge is a one- to two-semester, design-only competition, while the Build Challenge is a multiyear design-build competition.

“Now in its 20^th year, the Solar Decathlon continues to be at the forefront of building the next generation of student leaders who can address climate change through the built environment,” said Holly Jamesen Carr, Director of Solar Decathlon in the Building Technologies Office. “As these students take on the toughest challenges in the built environment, their bright ideas and creativity will be crucial in the transition to a clean energy economy.”

2023 Build Challenge

The number of teams competing in the 2023 Build Challenge has nearly tripled from the 2020 Build Challenge to 32 teams, and 16 of the 37 participating collegiate institutions will send teams to the Solar Decathlon Build Challenge for the first time. Over the next two years, these teams will design and build energy-efficient, fully functional homes in their communities to demonstrate creative solutions for real-world issues in the building industry.

How did participation in the Solar Decathlon affect the trajectory of your career?

My experience in Solar Decathlon brought me the confidence in changing my career path towards one that interests me. In my third year of university, I was exploring architecture classes and began learning about the design process and high-performance buildings. However, most of the work for these classes was done as individuals so the scope of work was focused mostly on the architectural function and aesthetic. Solar Decathlon exposed me to the interdisciplinary and collaborative nature of sustainable design, which has helped me adapt my experiences to my interests.

Competitors Represent the Next Generation of Energy-Savvy Architects and Engineers Who Will Build Our Clean Energy Future

WASHINGTON, D.C. — Secretary of Energy Jennifer M. Granholm yesterday joined college students from around the world to announce the winners of the U.S. Department of Energy (DOE) Solar Decathlon—a collegiate competition that challenges the next generation of building professionals to design and construct high-performance, low-carbon buildings powered by renewable energy. The 72 competing teams representing 12 countries designed resilient and energy-efficient, homes, schools, offices, and retail spaces; nine of which were constructed and presented in the first-ever Solar Decathlon Virtual Village on the National Mall in Washington, D.C.

Watch Sunday’s awards ceremony and Secretary Granholm’s remarks HERE.

“Our fight against the climate crisis is a lot like a decathlon, with all kinds of individual contests we need to get through—and we can’t win unless we do well in them all,” said Secretary Granholm. “Today’s decathletes are tomorrow’s architects and engineers who are going to help us achieve President Biden’s ambitious and achievable clean energy goals and build our net-zero future. I can’t wait to see their big ideas come to life in neighborhoods across the country and around the world.”

According to DOE analysis, today buildings account for approximately 74% of electricity use, 39% of total energy use, and 35% of carbon emissions in the United States. There are more than 125 million buildings in the nation that need to be retrofitted in order to achieve the Administration’s goal of net-zero emissions by 2050—which President Biden’s American Jobs Plan proposes to address. The Solar Decathlon supports a key strategy to bring that vision to life, by building a pipeline of energy-savvy workers who are prepared for millions of future jobs in design, construction, retrofitting, weatherization, and more.

About the Solar Decathlon

The Solar Decathlon is a collegiate competition that challenges the next generation of building professionals to design and construct high-performance, low-carbon buildings powered by renewable energy, while promoting student innovation, STEM education, and workforce development opportunities in the buildings industry. Since 2002, more than 20,000 students have participated in the Solar Decathlon, many of whom have gone on to become architects, engineers, and researchers. This year’s competition marks the 19th anniversary of the Solar Decathlon.

The Design Challenge is a one- to two-semester, design-only competition, while the Build Challenge is a two-year design-build competition.

Applications for the Solar Decathlon 2022 Design Challenge and 2023 Build Challenge will open this summer. Additional details are available on the Solar Decathlon website.

Today, Acting Assistant Secretary of Energy for Energy Efficiency and Renewable Energy Kelly Speakes-Backman officially kicked off the U.S. Department of Energy Solar Decathlon^® Competition Event during the Solar Decathlon Opening Celebration.

Students from 72 teams, representing 66 collegiate institutions and 12 countries, are competing for top prizes in the 2020 Build Challenge and 2021 Design Challenge during the Competition Event.

“I was deeply inspired by the ingenuity and perseverance of our Solar Decathlon teams, who have designed and constructed buildings that embody the spirit of innovation we need for a clean energy future,” said Acting Assistant Secretary Speakes-Backman. “These homes are a testament to the incredible skill and resolve of the next generation of building professionals, who share a sense of urgency in tackling the climate crisis and building more sustainable communities.” (more…)

A 100% clean energy economy capable of battling climate change will include a strong foundation of zero energy homes—a house that can produce as much energy as it uses. Such homes don’t have to be bare-bones and uncomfortable. Quite the opposite, in fact. Student-led teams competing in the U.S. Department of Energy Solar Decathlon^® Build Challenge are proving they can blend architectural design and engineering excellence with innovation, market potential, building efficiency, and smart energy production, all with the “comforts of home.”
