Honda has released more than 200 channels of Honda Smart Home US (HSHUS) energy and water consumption data—down to a one-minute resolution—covering the six-month period April-September 2015.
The Honda Smart Home showcases technologies that enable zero net energy living and transportation, including Honda’s home energy management system (HEMS), a proprietary hardware and software system that monitors, controls and optimizes electrical generation and consumption throughout the home’s microgrid.
The home is capable of producing more energy on-site from renewable sources than it consumes annually, including enough energy to power a Honda Fit EV for daily commuting. The home’s occupant will be able to use less than half of the energy of a similarly sized new home in the same area (Davis, California) for heating, cooling and lighting. The home is also designed to be three times more water-efficient than a typical US home.
In a post, Michael Koenig, the project leader for the Honda Smart Home, said that the data show overall water consumption was lower than expected, thanks largely to the thrifty water habits of the occupant family. For the first six months of data monitoring, the house was 40% below the best-practice estimate.
The monitoring data shows that while clothes washing and toilets consumed about the same amount of water as the best practice construction, our occupants were able to slash consumption via showers, baths and sinks, without sacrificing their quality of life. Low-flow fixtures play a role, but so does the conservation mindset.—Michael Koenig
