HERRIMAN — Tech firm Vivint and Utah homebuilder Garbett Homes have developed a house design that generates more energy than it uses.

The "Zero Home" uses solar power, building science and computer automation to create a dwelling that is completely energy-efficient, according to a press release.

Energy testing on the first such home in Utah showed that the house generates slightly more energy that it consumes during normal living conditions.

The prototype five-bedroom, 3.5-bathroom house at 5047 W. Ambermont Drive uses recycleable building materials and is expected to sell in the $350,000 to $400,000 range. It's monitored by a computer system that analyzes energy usage in real time.
