Cutting-edge technology solutions that not only appeal to today’s connected homebuyers, but also help make buildings greener and more energy efficient is more than just a trend—it’s the way of the future. For residential construction companies, keeping track of even the more futuristic-seeming projects is a good idea because one day, it could be the norm.

Piggybacking on its previous efforts, KB Home,, Los Angeles, Calif., recently debuted a Double ZeroHouse 3.0 at its Fiora at Blackstone community in El Dorado Hills, Calif.; the second one in the state. Similar to the company’s ZeroHouse 2.0 models, the new version—a single-story, 2,612 sq.ft., three bed/two bath home with a two-car garage—pursues net-zero energy usage.

KB Home says the new ZeroHouse 3.0 is called a “double” because it not only pursues net-zero energy, but also efficient water use. In both pursuits, KB Home has relied on partners such as SunPower,, San Jose, Calif., which provides clean energy through roof-mounted solar panels; Whirlpool,, Benton Harbor, Mich., which provides smart, energy-efficient appliances; and Nexus eWater,, Lancaster, Calif., which provides a home water recycling system called eWater Recycler.

The Double ZeroHouse 3.0 at Fiora also includes smart-home technologies that appeal to many homebuyers. For instance, KB Home says the model enables home automation and control via smartphone or tablet. The company is also part of the MyEnergi Lifestyle initiative led by Ford,, Dearborn, Mich., meaning the Double ZeroHouse 3.0 not only integrates smart home appliances and solar panels, but also plug-in vehicles, which all work together to reduce homeowners’ carbon footprints.

The company estimates the new model could provide an up to $4,500 annual savings in energy and water usage costs when compared to a typical resale home. If the promise of a reduced carbon footprint and a more connected home experience doesn’t speak to consumers, that number most likely will.
