In 1999, the Joint Legislative Energy Efficiency Code Study Committee was formed by the Arizona legislature to discuss possible adoptions of energy efficiency codes. As a result of the Committee's recommendations, the Arizona Legislature introduced and enacted in the 1999 legislature House Bill 2322.
Based on the results of these efforts, the state legislature subsequently passed HB 2541 on May 4, 2001, which resulted in Arizona Law 2001, Chapter 340. This statute established the Arizona State Energy Code, and further established a State Energy Code Advisory Commission to review and recommend changes to the State Energy Code. No mandatory statewide code has been promulgated by this body as of 2009. In addition, legislation adopted in 2003 requires state agencies and universities to achieve a 10% reduction in energy use per unit of floor area by 2008, and a 15% reduction by 2011.
On February 11, 2005, Gov. Janet Napolitano signed Executive Order 2005-05, requiring all new state-funded buildings constructed after February 11, 2005, to achieve at least a Silver LEED green building rating as well as meet the energy standards of ASHRAE 90.1-2004.
