The Stacked House is an exercise in geometric simplicity. The concept was to make the building envelope simple in order to apply high performance features to the walls in an effort to reduce energy consumption. In that simplicity there is also cost efficiencies due to the lack of complexity in the form.
One of the more unique details of the Stacked House is that it will have both an exterior weather resistant barrier and an interior air barrier. This is fairly new in building science and the redundancy minimizes air leakage within construction tolerances. More detailing in the architectural drawings was necessary to ensure that strips of the air barriers were added during framing and providing a better seal and more energy efficient design.
