High on a hill and far from city water or an electrical grid, a thorough investigation resulted in the addition of photovoltaic and hydro power (weighted toward solar in summer and hydro in winter) and worked to ensure the home wouldn’t use much energy. The building’s original orientation also helped as southern exposure allowed for the sun to be the main source of heat during the winter. A generous eave prevents much sun from entering the home during summer, thus keeping it cool. Large wooden shutters that slide closed like a second skin, cover the large windows at night to trap in most of the home’s daily solar heat gain.
