LANCASTER – KB Home on Wednesday unveiled its first ZeroHouse 2.0 during a special event at the builder’s Dawn Creek community in Lancaster. It’s the first KB home designed to achieve both net-zero energy status, and zero freshwater irrigation use by a family of four or more.
Dubbed the “Double ZeroHouse” for its dual emphasis on energy and water efficiency, the home is equipped to recycle drainwater on-site and reuse it for landscaping, minimizing the home’s overall demand for new water and eliminating the household’s need to use freshwater for the home’s established low-water landscaping.
KB Home estimates that the Double ZeroHouse 2.0 at Dawn Creek can conserve 150,000 gallons of water each year when compared to a typical resale home and landscaping, a reduction of approximately 70%. In addition, the ZeroHouse is designed to produce as much energy as it consumes, potentially yielding an electric bill of $0.
The first-of-its-kind KB home features an advanced water recycling system, a water recycling dishwasher, a “greywater” heat recovery system, super-efficient air ventilation and purification systems as well as a “fuel forward” garage with both an EV charger for electric and hybrid vehicles and a CNG fueling station for natural gas powered cars.
The home’s water recycling system treats greywater from bathroom showers, tubs, sinks, and washing machines to near-potable quality, and reuses it on the landscape. KB Home’s ZeroHouse 2.0 at Dawn Creek is the builder’s first to showcase this technology that, according to manufacturer’s estimates, can help a family of four recycle up to 40,000 gallons of water annually.
“With drought conditions currently affecting every corner of California, KB Home recognizes the importance of embracing innovations like the advanced greywater recycling system demonstrated in this ZeroHouse 2.0 that leverage the technology of the future to address the problems of today,” stated Tom DiPrima, executive vice president of KB Home’s Southern California division.
Water-recycling technology is also featured in the home’s dishwasher, which uses 33% less water than other dishwashers by saving water from the last rinse cycle for use in the first pre-rinse cycle of the next load.
The home’s greywater heat recovery system extracts energy from drainwater and uses it to preheat water in the home’s tankless water heater, further reducing water heating costs.
The ZeroHouse is connected to real-time water and energy monitoring systems that can track the water and energy used by the house from smart phones and tablets. Home automation technology included in the home puts the power to control its lighting, thermostat and security functions at its owners’ fingertips, and the home’s ‘smart’ refrigerator further reduces the home’s demand for energy by shifting energy-intensive functions to off-peak times.
“KB Home’s groundbreaking efforts to incorporate the latest water- and energy- saving technology into homes have been simply astounding,” said Lancaster Mayor R. Rex Parris in a city news release. “This management team is extremely proactive. They knew the technology was out there and rather than waiting for someone to map it out for them, they blazed the trail, discovering how to implement this wonderful energy-saving, clean power-producing equipment into their homes. These are exactly the type of partners we need in our journey to become the nation’s first Net-Zero City.”
Mayor Parris presented KB Home’s Tom DiPrima with a key to the city in Wednesday in recognition of DiPrima’s role in developing the partnership between KB Home and Lancaster.
