LAS VEGAS—Net-zero homes are going mainstream, if the home-building industry has anything to do with it.
The homes, which generate more electricity in a year than they use, have long been viewed as a niche product for the affluent who can afford custom homes. The chief problem is that it is expensive to get a home to net-zero status, and many customers aren’t willing to wait several years for their electricity-bill savings to cover the thousands of dollars they would have to spend on net-zero features such as solar panels and energy-efficient windows, doors and appliances.
But some builders, motivated by what they deem as rising demand from home buyers and state and local regulators, are aiming to change those perceptions by designing such homes for the mass market. Such a model home—the latest in the National Association of Home Builders’ annual New American Home series showcasing new-home designs —is on display this week in a hillside neighborhood 7 miles from the Las Vegas Strip as part of the trade group’s International Builders Show.
