California has adopted the nation’s first statewide green-building standards in what is, according to ever-punny Gov. Arnold Schwarzenegger, “literally a groundbreaking move.” The new California Green Buildings Standards Code requires builders to reduce energy use by 15 percent beyond current standards, target a 50 percent reduction in water used for landscaping, and use more recycled materials. The code also identifies site improvements including bicycle storage and designated parking spots for low-emissions vehicles. The standards will become mandatory in 2010, assuming we’re not all living in flying space pods by then.
