About the Nauhaus Prototype
2009 – The Nauhaus Prototype was made possible by a private venture of highly passionate and driven building professionals and volunteers. The Nauhaus Prototype is a building system born from a simple thought: a whole systems building design approach that combines the best of cutting edge modern building science with the advantages of traditional building materials and techniques.
Through a combination of passive solar design, a super-insulated building envelope, interior thermal mass, high performance windows and doors, and careful construction detailing, the Nauhaus Prototype was designed to be 80% more energy efficient than present code mandates, creating a healthy, comfortable indoor environment without need for a furnace or air conditioning. This substantial decrease in energy use allows renewable energy systems to be downsized. The consequent reduction in price brings self-sufficient power production and even carbon neutrality within reach. This “state of the art” building science is combined with site-harvested materials, rainwater harvesting, greywater irrigation, extensive outdoor living spaces, a lush edible landscape, small scale animal husbandry, and wildlife habitat to make sustainable homesteads a possibility even in densely populated urban neighborhoods.
