First things first: What's a Passive House? They're well insulated, virtually airtight buildings who must meet strict energy efficiency requirements. The benefit is that building passive can decrease home heating consumption by an astounding 90% and decrease overall energy consumption up to 75%.

An existing 1970s house was renovated to Passive House standards of construction, though the north-facing views and sheets of glass prevented it from meeting true Passive House energy calculations. The architects, Ryall Porter Sheridan, estimate that its "the second most energy-efficient structure on Long Island." Photo by: Ty Cole.
