Build Challenge

Teams competing in the Solar Decathlon Build Challenge work during a two-year period to design and build their houses, culminating in April 2021 with the Solar Decathlon Competition Event at the National Renewable Energy Laboratory in Golden, Colorado. Participants design and build complete, functional houses in their communities to demonstrate creative solutions for real-world issues in the building industry. Teams will compete and exhibit their solutions before panels of industry expert jurors. Select top-performing teams will also be invited to exhibit at the National Association of Home Builders (NAHB) International Builder’s Show in 2021. See the teams for the 2020 Build Challenge.

During the Solar Decathlon Competition Event in April 2021, Build Challenge teams will also have the opportunity to participate with 2021 Design Challenge teams, learn from presentations by thought leaders and collegiate peers, and engage with a variety of organizations about energy careers. Through local exhibitions, teams are recognized publicly, and the winning houses will be announced. The competition and winners are promoted through a variety of media outreach efforts, which provide participants and their collegiate institutions an opportunity for national exposure.

Collegiate institutions that participate in the challenge are recognized as leaders in cultivating career-ready, young professionals with cutting-edge skills. Industry partners who collaborate with teams gain national and local recognition and have the opportunity to interact with knowledgeable future design and construction professionals.
