(a) The department shall, at least once every seven years, perform an energy audit of each public building.(b) The department shall include in each energy audit required by (a) of this section recommendations for corrective measures to improve the energy efficiency and to minimize the life-cycle cost of the public building surveyed. These measures may include (1) energy conservation measures, (2) measures involving solar technology and other alternative energy systems, (3) energy management, and (4) maintenance and operating procedures and energy-related modifications. In recommending the corrective measures, the department shall give priority to changes in maintenance and operating procedures over measures requiring substantial structural modification or installation of equipment.(c) In this section, “energy audit” means a determination of
(1) the energy consumption characteristics of a building, including the size, type, and rate of energy consumption of major energy-consuming systems of the building and the climate characterizing the region where the building is located; and(2) a determination of the energy conservation and cost savings likely to result from appropriate energy-conserving maintenance and operating procedures and modifications, including the purchase and installation of energy-related fixtures.
