This building uses a combination of super insulation, passive solar and solar PV (and eventually solar hot water) to create a building that will use a small fraction (e.g. 20%) of the energy used by a typical home in the United States. It includes high thermal mass and several envelope technologies (concrete foam core sandwich, timber frame with SIPs, Larsen truss walls with dense pack cellulose, R-8 windows). The building is being built to Passive House standards with an emphasis on very tight envelope and few thermal bridges. It is also equipped to use solar hot water as a heating means should that be desired or required. Building is off-grid with wood heat as primary heat source.
Very quiet. Very stable temperature.
Top up battery electrolyte every 60 days
Efficiency or Sustainability Improvements:
Locally sourced timber frame. High thermal mass. Minimal disturbance to surrounding area. Focus on passive solar and strong connection to the outside.
Desire to build super efficient building that will benefit this and future generations
More planning before beginning
Experience with Installer:
Generally fine, but hard to find experienced people who really understand how make a really tight envelope

Open House Info:
Come see an off-grid home that is super insulated, runs on Solar PV and is in the later stages of construction. Still possible to see the construction details and learn how to put together a very tight building envelope, install a PV system and use advanced building materials from Europe. Built to Passive house standards. Even if you will not build a building yourself, we can provide advice on what to specify with your builder and major pitfalls to avoid.
