2020 Design Challenge Juries

Teams that compete in the annual Solar Decathlon Design Challenge must create residential or commercial building designs over one or two semesters. 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 six 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 Design Challenge Weekend. 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 individual jurors by Division below, or learn how the jurors evaluate projects in the Design Challenge Rules.

Edward Mazria is an internationally recognized architect, author, researcher, and educator. His seminal research into urbanization, climate change, sustainability, energy consumption, solar energy, and greenhouse gas emissions in the built environment has redefined the role of architecture, planning, design, and building in reshaping our world. He is the Founder and CEO of Architecture 2030, a think tank developing real-world solutions for 21st-century problems. He hosts the AIA+2030 Professional Education Series, served as a key player for the China Accord as well as the 2030 Districts movement in North American cities, and is involved in the Zero Tool and Achieving Zero, which is a framework of incremental building sector actions to ensure a carbon neutral built environment by 2050. Mr. Mazria recently introduced the 2030 Palette, a revolutionary new platform that puts the principles behind carbon neutral and resilient built environments at the fingertips of architects, planners, and designers worldwide.

This past year, he delivered the Roadmap to Zero Emissions to the United Nations Framework Convention on Climate Change, which presented a flexible approach to achieving zero CO2 emissions in the built environment by midcentury. He also issued the 2050 Imperative—a commitment to plan and design to carbon neutral standards—which has been adopted by the International Union of Architects and its regional professional organizations (representing more than 1.3 million architects) in 124 countries worldwide.

Mr. Mazria is a Senior Fellow of the Design Futures Council, a Fellow of the AIA, an Honorary Fellow of the Royal Architectural Institute of Canada, and he received an Honorary Doctor of Architecture degree from Illinois Institute of Technology.
