How the Home Works

Our 1,815-square-foot resort operates on 100 percent clean solar electricity; it doesn’t use propane, natural gas, or wood. It’s tied to the grid, but our electric meter goes both forward and backward, depending on whether we’re drawing electricity from the grid (as at night) or producing a surplus (as on sunny days).

To conserve energy, the walls and roof are made with structural insulated panels (SIPs), which are rigid foam sandwiched between layers of wood. The windows are triple-pane, and they’re positioned to let the sun warm the home in winter. The home is heated by two small Panasonic mini-split heat pumps, which also serve as air conditioners in summer. Our water heater has a small heat pump on top.
