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.
