In Fraser, Colorado, there’s a new net-zero energy house that was designed with impressive active and passive building technologies. It’s grid-tied and all-electric, using no fossil fuels thanks to the solar photovoltaics and evacuated tube solar thermal array. But the house isn’t the only thing powered by the sun. The 17-kW array also powers two all-electric plug-in vehicles.
Designed by Bryan Bowen and Kristen Uitto of Bryan Bowen Architects, Fraser Net-Zero Energy House has a thickly insulated envelope with 7″ closed-cell polyurethane and 4″ exterior rigid XPS foam walls (R60), 12″ of closed-cell polyurethane and a 2 1/2″ Insul-Span half SIP roof (R85.5), and an ICF foundation with GreenBlock and 4″ exterior rigid XPS foam (R24). Other materials include:
- American Clay plaster walls
- 3form counters
- Loewen exterior lift-slide doors
- Serious high-efficiency fiberglass windows
- Eco Dashboard real-time monitoring system
- Sundeck bamboo decking
- Ipe wood parquet decking
- Live Roof green roof
- LED and fluorescent lighting
- Hunter Douglas automated window shading/coverings
Also, the home is clad in Centennial Woods reclaimed snow fence and Umicore corrugated zinc siding, both of which contrast well with exposed concrete floors and massive timber trusses.
The Fraser Net-Zero Energy House is 5,232 square feet and built for the homeowner – an ultra-marathoner – with a home gym and Endless Pool, as well as regular living areas, a guest home, a two-car garage, and a woodshop outbuilding.
Uitto shared this stunning home with Jetson Green using the new submission form saying, “this warm and inviting home is truly built to stand the test of time” and “melds technology with poetry through a palate of natural materials both inside and out.”
