This single-family home, nicknamed the “A-Haus,” is the first house in Michigan to be certified by the Passive HouseA residential building construction standard requiring very low levels of air leakage, very high levels of insulation, and windows with a very low U-factor. Developed in the early 1990s by Bo Adamson and Wolfgang Feist, the standard is now promoted by the Passivhaus Institut in Darmstadt, Germany. To meet the standard, a home must have an infiltration rate no greater than 0.60 AC/H @ 50 pascals, a maximum annual heating energy use of 15 kWh per square meter (4,755 Btu per square foot), a maximum annual cooling energy use of 15 kWh per square meter (1.39 kWh per square foot), and maximum source energy use for all purposes of 120 kWh per square meter (11.1 kWh per square foot). The standard recommends, but does not require, a maximum design heating load of 10 W per square meter and windows with a maximum U-factor of 0.14. The Passivhaus standard was developed for buildings in central and northern Europe; efforts are underway to clarify the best techniques to achieve the standard for buildings in hot climates. Institute U.S. (PHIUS). The striking building is situated on nearly three acres of rural land, bordered by woods and farm fields, in Freeland, Michigan.

A few years into the housing bust, I started shopping around for a cabin to use as a getaway and vacation rental. I live in San Diego and I set my sights on the resort town of Big Bear Lake, in the San Bernardino mountains northeast of Los Angeles. Just 2½ hours away, it was a place where my family and I had spent many weekends skiing, snowboarding, mountain biking, and fishing.

In 1983, the Heron was one of five cookie-cutter models offered in Bay Country, a tract housing development in a suburb of Baltimore, Maryland. Perhaps a little ahead of its time, the design featured walls with 1-inch-thick expanded polystyrene (EPSExpanded polystyrene. Type of rigid foam insulation that, unlike extruded polystyrene (XPS), does not contain ozone-depleting HCFCs. EPS frequently has a high recycled content. Its vapor permeability is higher and its R-value lower than XPS insulation. EPS insulation is classified by type: Type I is lowest in density and strength and Type X is highest.) insulation over the standard 2x4 walls filled with fiberglass batts.

A Denver-area developer, New Town Builders, is aiming to make all of its new homes zero-energy-ready by the end of 2013.

“Our goal is to be 100% U.S. Department of Energy (DOEUnited States Department of Energy.) Zero Energy Ready certified on all of our single-family homes,” said Bill Rectanus, vice president of New Town Builders, which plans to build 150 single-family homes in the Denver metro area in 2013.

A Seattle couple spent two years searching for their dream home before deciding to build a new custom home. They turned to zero-energy-home builder Ted Clifton, Jr., who built them a modern two-story house with a mother-in-law suite and views of Lake Washington from the rooftop deck.

Clifton, the owner of of TC Legend Homes, calls the home a “positive energy home” — one that produces more energy than the home itself consumes. In fact, the home should produce enough electricity to power an electric car with the charging station set up in the garage.
