DER Pilot Home

This existing 1950’s split level home was transformed into a state of the art Deep Energy Retrofit (DER) Program sponsored by National Grid. The project design began in the winter of 2014  and construction was completed by the winter of 2016. The super insulated enclosure was partially paid for through financial incentives and technical support from National Grid, and  site evaluations by their partner, Building Science Corporation.

The construction of the project also became the  focus a teaching tool being developed for builders, called Pro-Craft Trade, who tracked the step by step construction of the well experienced  DER Team of David Joyce and Synergy Construction.

The Owners had a strong desire to keep a modern and open feeling to the house, particularly in the grand space which combined kitchen, dining, and living rooms all under one large open cathedral ceiling. The extended horizontal planes were accented by exterior future extended screen porch and entry platforms, were accentuated by the vertical entry plane at the west entry and east chimney mass housing the exhaust for the gas fireplace. Mature trees to south of the existing home were reviewed and tagged for removal by Concord conservation commission to allow future solar PV array for the home to also run the new air to air heat pumps.
