(a) The department in consultation with the State Energy Resources Conservation and Development Commission, with the concurrence of the Department of Finance, shall identify each public building in the department's state property inventory where it is feasible for that building to reduce energy consumption and achieve energy efficiencies, as well as to produce its own onsite electrical generation or reduce its level of peak demand electricity consumption using alternative energy equipment, thermal energy storage technologies, or cogeneration equipment.

(b) The department may consider a variety of factors, including, but not limited to, the size of the public building, its location, the ease of conversion to onsite electrical generation, peak demand reduction efficiency, cost effectiveness, and the amount of megawatts generated or shifted to off-peak periods.
