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.
Earth Bound Homes is involved with several ultra-green homes and this one in California deserves a mention. It was designed by Bill Leddy, LMS Architects, and built by Earth Bound Homes for David and Stephania Kaneda, receiving a Green Point Rated score of 268 and LEED Platinum certification.
This is the Helenowski Residence, a gut-rehab in Chicago that achieved the highest LEED for Homes point total ever with 119 points, according to LEED for Homes provider Alliance for Environmental Sustainability. The 3,300 square-foot renovation achieved an impressive HERS rating of 13 and is net-zero energy with the help of rooftop solar power and a vertical axis wind turbine.
Last weekend, I had the opportunity to tour this newly-built net-zero energy home in Park City, Utah. The Sungazing House, built by Tall Pines Construction and designed by Jean Yves Lacroix, is home to the O’Meara family of four and features impressive views of the surrounding area. Perhaps more impressive, however, is the fact that it’s pursuing Passive House, LEED Platinum, and NAHB Emerald certifications.
This is the Yannell Residence in Chicago, Illinois, a home that was designed and built as an exercise in net zero energy living — it produces at least as much energy as it uses over the course of a year. It received LEED Platinum certification in July 2009, and has been on a roll getting media attention all over the place. Some say it’s one of the greenest houses ever built, but one thing is for sure: it has a ton of interesting green elements.
This is the first LEED Platinum home in Vermont, although perhaps more importantly, it’s a documented and legitimate zero net energy home. From January 2008 to January 2009, the 2,800 square-foot, single-family residence exported 16 kWh of electricity to the grid. Over the same time period, a Bergey 10 kW net-metered turbine generated 6,286 kWh of on-site, green energy. Designed by Pill – Maharam Architects, the handsome farmhouse was built for a family of four and features a number of green elements:
