They’re singing “We Are the Champions” at the University of Maryland this week, but not because of a big win on the football field or the basketball court.

On Saturday, the team from Maryland won the 2011 Solar Decathlon for a house that featured a design that allowed water from the shower, clothes washer and dishwasher to be recycled, a green roof that let rainwater feed the landscaping and an inside wall that grew plants that could be used in cooking.

The 19 houses built as part of the decathlon were judged on 10 factors, including architecture, affordability, comfort and home entertainment. The Maryland home, called WaterShed, scored 951.151 points of a possible 1,000.

The team included students and teachers from the schools of architecture, engineering, computer science and agriculture.

“There are lots of tears of joy and relief,” said architecture team leader Leah Davies. “We are all so proud of the thought and hard work put into WaterShed.”
