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.
Inspired by the Chesapeake Bay ecosystem, the University of Maryland returns to the U.S. Department of Energy Solar Decathlon 2011 with WaterShed--an entry that proposes solutions to water and energy shortages. The house is a model of how the built environment can help preserve watersheds everywhere by managing storm water onsite, filtering pollutants from greywater, and minimizing water use. The photovoltaic and solar thermal arrays, effectiveness of the building envelope, and efficiency of the mechanical systems make WaterShed less thirsty for fossil fuels than standard homes.
The forms of the house highlight the path of a water drop. WaterShed's split butterfly roofline highlights storm water runoff from each module, directing and collecting it into the water axis at the core of the house. Water used within the house intersects this axis through a consolidated mechanical core.
Spatially, the house is designed as two "shed" modules slid apart along the central water axis and connected by a third module: the hyphen. The two larger modules express the programmatic intent of a live/work environment by physically separating the public and private realms. The hyphen houses the bathroom and highlights the connection between interior water uses and the wetland axis outside.
