Gottfried Green

I was hoping in the future to have a green wall vs. the green roofs.. University of MD won 2nd place in the 2007 Solar Decathalon. If I could have their LEAFHouse- shipped here and put on our lot I'd be happy to move in. They explain everything they've used and done on their website so I'll have a reference for all the details. They use their exterior green wall for rainwater mitigation. "In typical housing developments, water from rooftops and paving is allowed to run offsite; storm sewers must be constructed to carry the water to the nearest body of water, carrying with it all the contaminants it picks up along the way. The LEAFHouse includes a rainwater management system that minimizes run-off and the associated environmental impacts.

Rainwater collection at LEAFHouse is a multi-layered system. At the roof level, downspouts collect rainwater that, at the post-competition site of LEAFHouse, will be directed to a cistern from which the water will be used for garden irrigation. The Green Wall will likewise act as its own downspout, directing water from the roof down to a rain garden. Finally, our decks are equipped to catch the rainwater that passes through them and direct it to a cistern for on-site non-potable uses (irrigation, car-washing, etc.)."
