In 2012, Governor Brown issued a sweeping executive order directing DGS and all other state agencies, departments and other state entities to reduce energy use by 20 percent by 2018 (compared to a 2003 baseline). In addition to energy reduction goals, the executive order also called for a reduction of 20 percent of state water use by 2020 (compared to a 2010 baseline). The water use reduction goal was accelerated to 25 percent by the end of 2015 under the state's first-ever statewide mandatory water reduction directive.
To achieve these aggressive goals, DGS and other state agencies are using the U.S. Green Building Council's Leadership in Energy and Environmental Design (LEED) program to rate buildings for qualities like energy efficiency, water conservation and indoor air quality. Under Governor Brown’s green building executive order, new or renovated state-owned buildings and leased facilities larger than 10,000 square feet and existing state buildings and leases larger than 50,000 square feet must obtain LEED certification.
