Michelle Kaufmann judged this year's Solar Decathlon and here are some of the photos she took at the event which took place at the National Mall's West Potomac Park.
Appalachian State University was inspired by traditional Appalachian settlements for its U.S. Department of Energy Solar Decathlon 2011 entry. Solar Homestead is composed of multiple buildings that form a self-sufficient ensemble. Six outbuilding modules connect to form the Great Porch, an outdoor living space protected by an 8.2-kW trellis of bifacial solar cells. Inside, the 833-ft2 (77-m2) house features two bedrooms, a day-lit bathroom, energy-efficient appliances, and a versatile living and dining area. The Solar Homestead also includes an independent 120-ft2 (11-m2) Flex Space that can be used as a home office, art studio, or guest quarters.
