The following features help reduce our need for external energy:
An 85-ft2, 960-watt array of photovoltaic (PV) panels helps offset some of our dependency on commercial electric energy by generating solar electricity.
Blown cellulose, made from recycled newspapers, nearly doubles the R-value of our insulation. (The higher the R-value, the greater the insulating effectiveness.) By using horizontal strapping on the walls, we were also able to increase the depth of the exterior walls (and therefore the thickness of the insulation) from 2′ x 4′ to 2′ x 6′.
Sprayed urethane foam seals the building and creates an airtight envelope, which limits infiltration of cold air and associated heat loss in the winter.
An energy-recovery ventilation system transfers more than 80% of the heat energy in stale exhaust air to incoming, fresh, outdoor air.
Highly-efficient windows reduce heat loss in the winter and limit heat gain in the summer.
Lighting systems were designed with energy efficiency in mind.
Composting toilets reduce electricity use.
Our wood pellet boiler generates heat from a renewable forest resource, and burns at 90% efficiency.
Most spaces have individual lighting and heating zones, so we’re only using energy where and when we need it!
