This is an interesting example of how simple improving sustainability and decreasing one’s carbon footprint can be. The WaterShed, as it’s called, is a house constructed for the Solar Decathon competition, and is designed to capture both solar energy and rain water. Solar panels on the roof are combined with a greenroof that aids in regulating the building’s internal temperature. Integrated solar panels on the roof allow the building to generate 100% of its own energy.
