Over 4,000 students from around the world have their solar-powered homes on display for this year's Solar Decathlon. Sponsored by the U.S. Department of Energy, the event takes place on the National Mall's West Potomac Park featuring high energy efficient homes. Eco-architect extraordinaire Michelle Kaufmann is one of this year's judges and here are some of the photos she has captured from the event.
Team New Jersey uses concrete panels in all roof, wall and floor assemblies plus has an inverted-hip shape roof that is calibrated for both solar and rainwater collection.
