Super insulated house design, with 100% electrical power,augmented with a wood stove in the winter for heat. No PVs or solar thermal hot water were installed in the initial build. The objective was to insulate with 12 inch walls and 18in roof insulation. Triple glazed windows and doors were used through out, and all penetrations of the walls were managed for minimal heat loss.

What You Need to Know


Annual Energy Usage 250 Garland Rd Current Operation: House occupied for 6 months in summer , elect heat for winter @ 45 F. Heat: 1262 kWh $265 40% of total for the period Oct to March Plug load: 1866 kWh $392 60% of total for the period May to Oct. total use 3128 kWh $657 per year.
