Arizona has some requirements for their buildings contained within their statutes. A.R.S. § 34-451 requires the Department of Administration, the Department of Transportation and the Arizona Board of Regents to reduce their energy use by 15% by July 1, 2011 using July 1, 2001 through June 30, 2002 as the baseline year. As a whole, the three building systems reduced their energy usage on a BTU per square foot basis by 15.8%, meeting the reqirements of the statute.
Electric District No. 3 of Pinal County (ED3) provides incentives for their residential and business customers to invest in photovoltaics (PV). Residential and commercial customers installing PV systems up to 10 kilowatts (kW) in capacity may be eligible for rebates of $0.20 per watt. Commercial customers can install PV systems up to 20 kW in capacity. In no case can the rebate be greater than 50% of the installed cost. Equipment requirements and other details are available through the link above.
Duncan Valley Electric Cooperative is providing rebates to for the purchase of renewable energy systems through its SunWatts program. Photovoltaic (PV) and wind energy systems 10 kilowatts (kW) or less can receive an upfront rebate of $1.00 per watt, up to 40% of the system's cost. Solar water heating systems can receive a rebate of $0.75 per kilowatt-hour (kWh) of estimated energy savings in the first year. PV and wind systems larger than 10 kW and other renewable energy types may be eligible for a performance-based incentive awarded on a competitive basis.
Tucson adopted an ordinance in June 2008 that requires all new single-family homes and duplexes in Tucson to be "solar-ready." The ordinance was developed by a stakeholder group which included Technicians for Sustainability, the Tucson Association of Realtors, the Sierra Club, the Southern Arizona Homebuilders Association, architectural professionals, solar energy companies and elements of the city government.
The City of Tucson passed Resolution No. 20193 on September 27, 2005, to encourage the installation of solar energy systems throughout the city. The resolution established a policy whereby the director of the Department of Planning and Development Services will waive the fee paid by an applicant for a permit for the installation of a qualifying solar system up to $1,000 for a single installation, or $5,000 for a subdivision or multiple project sites. Other resolutions have since been passed to maintain this permit fee waiver after its expiration.
In 2005, Scottsdale approved a green building policy for new city buildings and remodels. The resolution requires all new, occupied city buildings of any size to be designed, contracted and built to achieve certification by the U.S. Green Building Council's Leadership in Energy and Environmental Design (LEED) Program at the "Gold" certification level as long as there is a payback period of no more than five years for projects designed to the Gold Standard.
Scottsdale’s Green Building Program, established in 1998, was the first such program in Arizona with an emphasis on residential home construction. It was developed to encourage environmentally responsible building in the Sonoran Desert region by incorporating healthy, resource- and energy-efficient materials and methods in the design and construction of homes. The program’s goals are to reduce the environmental impact of building; achieve both short and long-term savings of energy, water and other natural resources; and encourage a healthier indoor environment.
In 2008, the Phoenix City Council approved a renewable energy goal for the city. The city aims for 15% of the electricity used by the city to come from renewable energy sources by 2025. This goal mirrors Arizona's Renewable Energy Standard of 15% of electricity from renewable energy by 2025. The city plans to achieve this goal through renewable energy installations that are either city-owned or city-sponsored, primarily through public-private partnerships. The city council will periodically review progress towards meeting the goal and will set milestones to track progress.
The city of Phoenix was awarded a $25 million federal grant from the U.S. Department of Energy Better Buildings Neighborhood Program and the American Recovery and Reinvestment Act (ARRA) to launch the Energize Phoenix program in partnership with Arizona State University and with support from Arizona Public Service. The Energize Phoenix program saves energy, creates jobs and will transform a diverse array of neighborhoods along a 10-mile stretch of the Metro light rail.
