U.S. Department of Energy Solar Decathlon Competition Guide: 2021 Design Challenge and 2023 Build Challenge

The U.S. Department of Energy (DOE) Solar Decathlon® is a collegiate competition, comprising 10 Contests, that challenges student teams to design and build highly efficient and innovative buildings powered by renewable energy. The competition gives teams the option to participate in one of two Challenges: the Design Challenge or the Build Challenge. Teams entering the Design Challenge must select from seven allowable building types ("Divisions") to create their design. Teams entering the Build Challenge will build a residential unit locally and compete nationally. Whether participating in the Design Challenge or the Build Challenge, all teams are evaluated across 10 Contests. The Competition Guide outlines competition history and structure, descriptions of the 10 Contests, and competition details for both the 2021 Design Challenge and 2023 Build Challenge.
