Is Toyota the future of green homes?
In July, the Wall Street Journal carried an amazing story about a small division of Toyota building homes with 60-year warranties. According to the article, “Toyota’s aspirations as a home builder are also gaining new importance with the planned launch by 2010 of its plug-in vehicles, gas-electric hybrid cars with powerful lithium-ion batteries that drivers will need to recharge at home. The car maker is testing an electricity-monitoring system in its homes that would charge the vehicle during off-peak hours to keep utility bills low, while the car’s battery can serve as an electrical backup, powering the home during blackouts.” Toyota has been building modular, factory homes for years, while the U.S. continues to rely on outmoded systems of site-built housing that meet no real goals for sustainability. The great housing “correction” (read crash) of 2007 and 2008 is likely to persist as we work off millions of unoccupied homes from inventory and foreclosure. Maybe the time has come for home builders to embrace the off-site factory, but with a green building twist. At this point, they’ve little to lose.
