2021 Design Challenge Juries

Teams that compete in the annual U.S. Department of Energy Solar Decathlon® Design Challenge spend up to two semesters creating residential or commercial building designs. Designs are evaluated on how well they meet the nation's rapidly evolving demand for buildings that are innovative, cost-effective, quick to build, high-quality, resilient, grid interactive, efficient, and locally responsive. Teams choose one of seven building type Divisions in which to compete. Winners from each Division are determined by juried evaluation across all 10 Contests and awarded with trophies at the annual Solar Decathlon Competition Event. Two Design Challenge Grand Winners are also selected from the first-place teams—one from the residential Divisions and one from the commercial Divisions—and are provided with a special award.

Learn more about the 2021 individual jurors by Division below, or visit the Design Challenge Rules to learn how the jurors evaluate projects..
