It's a nice ecosystem for birds and bees and butterflies." The green roof absorbs much of the rainfall that otherwise would flow Into the city's stormwater drains, while the rest Is collected in rain barrels that the couple uses to Irrigate their lawn and garden.
The home's Interiors echo the angular look of the exterior, whose lower half was re-clad In FSC-certified fiber cement board siding while the second floor Is outfitted with durable corrugated metal siding. Energy-efficient fixtures and appliances—Including a 92-percent-efflcient furnace and 86-percent-efflcient gas water heater—further reduce the home's carbon footprint. Low-flow fixtures and dual-flush toilets reduce water use by 64 percent over other homes of a similar size.
To complete the Interior, Flynn and Nelson used local and recycled materials whenever possible, as well as low- or no-VOC paints and adhesives that preserve Indoor air quality. "We didn't want the materials Inside our house to make us sick," Flynn says. Sustainable finishes range from recycled glass terrazzo and recycled paper countertops to salvaged oak flooring and reconstituted wood veneer cabinetry faces.
The challenge of transforming an existing structure Into an eco-friendly dream home, at a cost of less than $140 per square foot, was exacerbated by the project's compressed time frame—the design process was completed In two months and the renovation In five months. "In any kind of remodeling project, you're never quite sure what you're going to get Into when you tear open a wall. Where we expected there would be insulation, there wasn't any. Where we didn't expect there to be, there was," Flynn says. "We were just one step ahead of the contractor every day. The challenge was keeping up with ourselves. We found out you could do It if you weren't overly dependent on sleep."
The project Is already receiving both local and International attention In addition to Its win In the Greenhouse category of the 2009 Evergreen Awards. AIA Minnesota and Mpls.St.Paul magazine honored EcoDEEP Haus with a Residential Architects Vision and Excellence Award, and the Minneapolis Star Tribune will feature It as a 2009-10 Home of the Month. Discovery's Planet Green network also plans to Include the home In a show on the world's greenest homes that will air this fall.
"When you can double the size of the house and use less energy than before, that's Impressive," Flynn admits. "And we've done It in a way that's sleek and modern and new."

Ever wondered what wood turning is all about? Here are some invaluable information on how to make beautiful items out of wood! That one little strategy from A Course In Wood Turning that I implemented not only worked, but the results were completely astonishing. I had never seen anything like it! Now, keep in mind that I had tried a lot of other products up until this point. You name it, I probably tried it! That’s how desperate I was to improve my skills with wood turning.
