Energy Standards for Public Buildings
Arizona law requires that new state building projects over six thousand square feet follow prescribed solar design standards. Solar improvements should be evaluated on the basis of life cycle costs. Affected buildings include buildings designed and constructed by the department of administration, school districts and universities. These projects must include an evaluation of: (a) proper site orientation; (b) active and passive solar energy systems for space heating; (c) solar water heating; and (d) use of solar daylighting devices. 

From 2010 to 2012, solar photovoltaic systems have been installed at seven state government facilities, providing an estimated 650 kW of power. In one building, a 50 kW system has reduced energy costs by more than $38,000 since its installation in August of 2010.
