Fifty-seven teams from 63 collegiate institutions have earned a spot in the final stage of the U.S. Department of Energy Solar Decathlon^® 2023 Design Challenge.

“Solar Decathlon has pioneered energy efficient building designs for more than two decades; this year’s finalist teams showed there is always room to push the envelope on zero energy buildings,” said Rachel Romero, Design Challenge competition manager.

Finalist teams were selected at the Semifinal Competition Event, held virtually February 24–25, 2023.  Teams presented their zero energy building designs to a panel of industry experts and finalists were selected based on their innovations, technical plans, and the quality of their presentations.

The competition includes residential and commercial designs in six different divisions: New Housing, Retrofit Housing, Attached Housing, Multifamily Building, Office Building, and Education Building. Up to 10 teams were selected in each of the contest divisions.

Finalist teams will compete to win their division, and possibly become one of two overall grand winners, at the hybrid Solar Decathlon Competition Event, April 20–23, 2023, in Golden, Colorado, at the National Renewable Energy Laboratory. The event will also include virtual participation options, networking sessions, and the announcement of the 2023 Build Challenge winners.

“As the premier sponsor for Solar Decathlon this year, we are thrilled to honor the finalist teams in the Design Challenge,” said Deb Cloutier, chief sustainability officer at Legence. “The experience students gain during this program is foundational to the design of energy-efficient and sustainable buildings in real life—some of our best engineers today are Solar Decathlon graduates.”

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.

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.

Save the Date for the Solar Decathlon Competition Event; Virtual Format Opens Participation to Broader Audience

Mark your calendars! The U.S. Department of Energy Solar Decathlon^® will host its rescheduled 2020 Build Challenge and 2021 Design Challenge competition events virtually, from Thursday, April 15 to Sunday, April 18, 2021. This virtual event will feature dynamic team presentations, interactive sessions, and networking opportunities for all collegiate teams in the United States and around the world.

The Build Challenge competition event was previously scheduled to be on the National Mall in Washington, D.C., in summer of 2020. The annual Design Challenge competition event is traditionally hosted by DOE’s National Renewable Energy Laboratory, in Golden, Colorado.

“While we will miss celebrating the excitement and passion in person, we want to ensure the teams are still given an opportunity to complete this unparalleled and valuable experience,” said Holly Jamesen Carr, director of Solar Decathlon for the Building Technologies Office. “We have seen how this competition has positively impacted the trajectory of many careers and elevated the importance of building efficiency.”

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

I knew I was interested in zero energy buildings, but the Solar Decathlon cemented for me that I wanted to make this field my career. Furthermore,  as I started working with the multidisciplinary team I assembled for the Race to Zero, I realized the importance of an integrated design process. This was one of the reasons I ended up at the MIT Sustainable Design Lab for my master’s; the lab is multi-disciplinary and focused on tools and analyses that architects, engineers, and policy-makers can all understand.

 Describe a work outcome, building project or other achievement you are most proud of and how (if) it relates to your experience with Solar Decathlon.

At MIT, I have been working with other members of my lab to make urban building energy modeling tools accessible to every city so that they can make physics-backed decisions on how to meet their emissions reduction goals. Through Solar Decathlon trainings and collaborations, I learned the applied building physics that underlie every building upgrade strategy we propose to meet these emissions reduction goals.

Zach at VERMOD Homes, a project that he sought out, which was inspired by his Solar Decathlon work. He documented improvements to the factory process for their zero-energy manufactured homes.

This month in our #SDLivingtheDream series, you’ll meet Brett Horin, who competed with Illinois Tech in the 2018 Design Challenge and who has gone on to work in energy modeling in the architecture industry, fueled by his experience in the Solar Decathlon.
