Net Zero Deep Energy Retrofit

Amherst, MA: Cottage Street Deep Energy Retrofit

Completed in 2009

My first project was begun as a renovation and - with the right clients at the right time - became my first Net Zero Deep Energy Retrofit. This superinsulated airtight home needs very little energy to provide for a family of four, and it makes all it needs on the roof with solar panels.

Years of deferred maintenance made the 1880s home a perfect retrofit project for a young family looking to settle down in the Pioneer Valley. With Steve Ferrari of FCM Smart Build (construction management) and Holden Builders (constructor), this was our first project using exterior insulation, and a great test drive for a package that would become standard: electric based heat pump heating and cooling, balanced whole-house ventilation, and clean modern interiors.
