Arizona law requires that new state building projects over 6,000 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.
