World's Greenest Homes Season 1 Episode 9 Suncadia

Situated in an exclusive conservation area and golf resort outside Seattle, Washington, this award-winning, 3,000 square foot home features superior insulation and eco-friendly finishes throughout. Built to blend in with its natural surroundings, the home boasts a two-story lounge, a bronze kitchen sink, a recycled copper bathtub, and a computerized central control system.

In just 18 months, this traditional 1940's bungalow outside Minneapolis was transformed into an award winning, super-green, energy-saving home. Called the "Sustainable House," it's loaded with almost every green feature imaginable, including low-flow fixtures, a closed combustion gas fireplace, triple-glazed argon-filled windows, geothermal wells for heating and cooling, and huge underground cisterns for storing rainwater.
