04-01-16 2 Geeks, 2 Houses on Martha's Vineyard Pro Tour

 Registration is closed for this event

Spend a day on Martha’s Vineyard touring two recently completed high-performance houses. The first house is a completely new structure, purpose-built to incorporate high performing energy systems and materials. The second house is a deep energy retrofit, where an existing house was reworked to become a net zero home. Hear about the different approaches to these projects, which required different strategies to achieve the same energy goals.

Brice Delhougne and Marc Rosenbaum are the building energy geeks at South Mountain Company and these are the houses they built for their families. These guys are hands-on and measure a lot, so they understand some of the less obvious aspects of how the houses and systems perform.
