Passive House retrofits are an inspiring cause, but what, at the end of the day, are they worth? To answer, this workshop compares and contrasts the goals, methods, costs and post occupancy performance of two renovation projects: one—the JP Green House—seeking Passive House status on a shoestring budget, and the other—a deep energy retrofit of a Belmont two-family—aiming for dramatic savings but stopping shy of Passive House standards. Summing it all up, a moderated discussion will explore the suitability of the Passive House standards to retrofits in the New England climate.
