ATLANTA — In 2010, in the nippy environs of northeastern Canada, a family of six submitted to an experiment. Their task: spend one year living in one of the most energy-efficient homes built in North America. The house in New Brunswick looked like others except for the solar panels on the roof. But by year’s end, there was a more substantial difference — it was the only house on the block with a nonexistent energy bill.

“The house we built generated enough electricity for two families,” said Tom Black, vice president of Eco Plus Group USA, which partnered with Bosch to create the home.
Fast forward two years, and they have done it again, building the first Bosch Net Zero home in the United States at Serenbe in Chattahoochee Hills, Ga. The house, through the use of geothermal heat and solar voltaic panels, is designed to generate more electricity than it uses. The excess energy is stored on the distribution grid of GreyStone Power Corp., where it is redistributed as needed. At the end of the year, the series of energy credits and debits tracked by GreyStone should be at or near zero.
