(a) applicable to the type of equipment being purchased or if the equipment meeting that standard is not reasonably available, the department shall ensure that energy consumption within a building, structure, or facility and all equipment that is purchased under each contract administered by the department maximizes energy efficiency to the extent technically and economically feasible. The department shall not determine that equipment that meets the applicable standard under par. (a) either is not reasonably available on the basis of cost alone or is not cost-effective unless the difference in the cost of the purchase and installation of the equipment that meets the standard and the equipment that would otherwise be installed is greater than the difference in the cost of operating the equipment that meets the standard and the equipment that would otherwise be installed over the anticipated life of the equipment.
