South Carolina Code 48-52-640. Energy conservation products marketed to State; certification and procurement requirements
(B) Energy conservation products certified by the State Energy Office may be purchased by a state agency subject to the state procurement code, but only if the State Energy Office considers use of the energy conservation product more cost efficient than an uncertified product over a five-year period. The State Energy Office may certify only a product that meets or exceeds the Federal Energy Star standards designed by the United States Environmental Protection Agency and the United States Department of Energy.
(C) A state agency shall submit a disclaimer statement to the State Energy Office with its annual report stating that it did not purchase an energy conservation product that had not been certified by the State Energy Office.
(D) Each state agency head shall require the agency’s procurement officer or other person authorized to purchase supplies for the agency to replace an incandescent light bulb used by the agency with a compact fluorescent bulb when the incandescent bulb needs to be replaced, and if the agency determines use of a compact fluorescent bulb is more cost effective over a five-year period than use of an incandescent bulb. A state agency may purchase incandescent bulbs for the agency if the agency verifies, in writing, that compelling circumstances require the use of incandescent bulbs.
