The Carbon Positive House was completed a number of years ago to free us of modern day lifelines and make significant contributions to society. Our Carbon Positive house was a prototype to discover what was possible for an ever-changing environment. The components and methods used have changed over the years. The Carbon Positive project costs are highly dependent on the size, the complexity of the design, the level of finish and the surroundings. The Carbon Positive House moves beyond carbon zero by making additional ‘positive’ contributions, producing more energy on-site than the building requires. Inside, the carbon-positive (or energy-generating) home features an indoor garden, lots of windows, and cooling tubes that force cool air from the earth into the home. Outside, homeowners will enjoy the benefits of solar panels and mechanisms that recycle old water for reuse. The end result: A home that emits just 1,016 tons of carbon dioxide over its lifetime--or the equivalent of taking about 270 cars off the road and planting 6,989 native trees.
