What is a Net Zero Home?

  • A home that creates as much energy as it consumes

How do we do it

  • Start by insulating and sealing the building to minimizing heat and cooling losses
  • Add controlled passive solar heating
  • Install exceptionally high-efficiency ventilation
  • ventilate the home with preheated fresh air, recapturing up to 84% of the heat in the stale air with an ERV.
  • Use efficient appliances
  • Replace the small amount of energy consumed with clean power and heat from solar collectors
