CA Executive Order S-20-04, issued in July 2004, required state agencies and departments to reduce their energy consumption by 20% from 2003 levels by 2015. The order also directed the Division of the State Architect to develop new green design guidelines for public schools. California's Green Building Action Plan, which supplemented EO S-20-04, included specific requirements designed to help the state meet its overall goal, such as the benchmarking of all state-owned buildings for energy efficiency by 2007.
CA Executive Order B-18-12, signed in April of 2012, updated some of these requirements while rescinding the earlier Order. It adjusted the energy savings targets such that grid-based energy purchases must be reduced by 20% by 2018 using 2003 as a baseline. New state buildings and major renovations started after 2025 must be constructed to be zero net energy, while 50% of existing square footage must be in the process of achieving zero net energy by 2025. Additionally, new buildings or major renovations larger than 10,000 square feet must earn the "Silver" level of LEED certification and incorporate on-site renewable energy if economically feasible. The Green Building Action Plan further requires existing State buildings over 50,000 square feet to complete LEED-EB certification by December 31, 2015 to the extent it’s cost effective. The Department of General Services is also working with State agencies to develop policies and guidelines for the operation and maintenance of State buildings to achieve operating efficiency improvements and water and resource conservation, and to continually update and incorporate these into the State Administrative Manual (SAM).
In December 2012, the California Energy Commission adopted the AB 1103 Nonresidential Building Energy Use Disclosure Program regulations, which went into effect July 1, 2012 for buildings over 50,000 square feet. The program will apply on January 1, 2014 for buildings over 10,000 square feet; and on July 1, 2014, for buildings equal to or greater than 5, 000 square feet. The regulations require energy use disclosure prior to the sale, lease, or financing of a whole building using the U.S. environmental Protection Agency’s ENERGY STAR Portfolio Manager benchmarking tool to document the building benchmarking data to be disclosed in the reports required by the regulations.
