(1) The general assembly authorizes and directs that state agencies and state institutions of higher education shall employ design and construction methods for real property under their jurisdiction, in such a manner as to further the policy declared in section 24-30-1304, insuring that life-cycle cost analyses and energy conservation practices are employed in new or renovated real property. (2) The life-cycle cost analysis must include but not be limited to such elements as: (a) The coordination, orientation, and positioning of the facility on its physical site; (b) The amount and type of fenestration employed in the facility; (c) Thermal performance and efficiency characteristics of materials incorporated into the facility design; (d) The variable occupancy and operating conditions of the facility, including illumination levels; and (e) Architectural features which affect energy consumption. (f) (Deleted by amendment, L. 2014.) (3) The life-cycle cost analysis performed for real property with a facility of twenty thousand or more gross square feet with significant energy demands must provide but not be limited to the following information: (a) The initial estimated cost of each energy-consuming system being compared and evaluated; (b) The estimated annual operating cost of all utility requirements, including consideration of possible escalating costs of energy. The office may rely on any national or locally appropriate fuel escalating methodology approved by the office of the state architect in performing life-cycle cost analyses. (c) The estimated annual cost of maintaining each energy-consuming system; (d) The average estimated replacement cost for each system expressed in annual terms for the economic life of the facility; (e) The use of biofuel to provide supplemental or exclusive heating, power, or both for the facility. For a renovation of such a facility, the cost analysis regarding the use of biofuel must consider any stranded utility costs; and (f) An energy consumption analysis of such real property's heating, ventilating, and air conditioning system, lighting system, and all other energy-consuming systems. The energy consumption analysis of the operation of energy-consuming systems in the real property should include but not be limited to: (I) The comparison of two or more system alternatives; (II) The simulation or engineering evaluation of each system over the entire range of operation of the real property for a year's operating period; and (III) The engineering evaluation of the energy consumption of component equipment in each system considering the operation of such components at other than full or rated outputs. (4) The life-cycle cost analysis shall be certified by a licensed architect or professional engineer, or by both architect and engineer, particularly qualified by training and experience for the type of work involved. (5) In order to protect the integrity of historic buildings, no provision of section 24-30- 1304 or this section should be interpreted to require such analysis with respect to any real property eligible for, nominated to, or entered in the national register of historic places, designated by statute, or included in an established list of places compiled by the state historical society. (6) Selection of the optimum system or combination of systems to be incorporated into the design of real property must be based on the life-cycle cost analysis over the economic life of the real property, unless a request for an alternative system is made and approved by the office prior to beginning construction. (7) The principal representatives of all state agencies and state institutions of higher education are responsible for implementing the provisions of this section and the policy established in section 24-30-1304. (8) The provisions of section 24-30-1304 and this section shall not apply to municipalities or counties nor to any agency or department of any municipality or county. (9) Repealed. (10) As used in this section, unless the context otherwise requires: (a) "Biofuel" means nontoxic plant matter consisting of agricultural or silvicultural crops or their byproducts, urban wood waste, mill residue, slash, or brush. (b) "Energy consumption analysis" means the evaluation of all energy-consuming systems and components by demand and type of energy, including the internal energy load imposed on real property by its occupants, equipment, and components and the external energy load imposed on the real property by climatic conditions.
