High-Performance Foursquare

This reinterpretation of the classic American Foursquare brings space planning for modern family living and 21st-c. energy efficiency, materials, and technology. The home is a right-sized Passive House (seeking PHIUS+ certification) designed to be healthy, efficient, affordable, and fit to its neighborhood. As a Passive House, it uses only a tenth of the heating and cooling energy of a built-to-code home, and about 65% less energy overall; it is also designed to be Zero Energy Ready, meaning that with the addition of a solar electric array, the house can produce as much energy as it uses. Indoor air quality and occupant health are a primary objective as well, so no-added-formaldehyde panel materials, no-VOC, non-toxic paints, and Greenguard certified sealants, caulks, and adhesives were used along with a continuous demand-controlled ventilation system to provide superior air quality.
