The High-Performance Four Square 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 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 very small solar electric array, the house can produce as much energy as it uses.  The Passive House envelope and design ensure the most cost effective path to net zero or even Net Positive.  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.   As an Evolutionary Home Builders standard, the home was third party lab tested for indoor air quality post construction.

The site is small, with large zoning setbacks, so the space planning was crucial to bringing a good layout together with high performance. This house for a family of six packs a lot into a small package: although only 2,000s.f. above grade (2,350s.f. interior conditioned floor area including basement), it has five bedrooms, 3.1 baths, an office, a walk-in pantry, and a rec room on top of the open living spaces. Outside the thermal envelope is a 2-car garage and mudroom.

The home is smart in its design and construction, but also can be controlled with smart home technology.  Experience a complete home automation and control package that can be controlled with phones or tablets while home or away.  This includes security alarm, whole house audio, lighting control, TV / video media, and fresh air systems.  An energy dashboard monitors real time energy use to inform occupants of their energy which leads to additional savings.  Another unique technology is the hot water delivery system that ensures hot water within seconds creating optimized comfort, significant energy savings, and increased water efficiency.
