255.254  No facility constructed or leased without life-cycle costs.--

(1)  No state agency shall lease, construct, or have constructed, within limits prescribed herein, a facility without having secured from the department a proper evaluation of life-cycle costs, as computed by an architect or engineer. Furthermore, construction shall proceed only upon disclosing, for the facility chosen, the life-cycle costs as determined in s. 255.255 and the capitalization of the initial construction costs of the building. The life-cycle costs shall be a primary consideration in the selection of a building design. Such analysis shall be required only for construction of buildings with an area of 5,000 square feet or greater. For leased areas of 20,000 square feet or greater within a given building boundary, a life-cycle analysis shall be performed, and a lease shall only be made where there is a showing that the life-cycle costs are minimal compared to available like facilities.

(2)  On and after January 1, 1979, no state agency shall initiate construction or have construction initiated, prior to approval thereof by the department, on a facility or self-contained unit of any facility, the design and construction of which incorporates or contemplates the use of an energy system other than a solar energy system when the life-cycle costs analysis prepared by the department has determined that a solar energy system is the most cost-efficient energy system for the facility or unit.

(3)  After September 30, 1985, when any state agency must replace or supplement major items of energy-consuming equipment in existing state-owned or leased facilities or any self-contained unit of any facility with other major items of energy-consuming equipment, the selection of such items shall be made on the basis of a life-cycle cost analysis of alternatives in accordance with rules promulgated by the department under s. 255.255.
