Notwithstanding any provision of the California State University Contract Law and any other provision of law to the contrary, the trustees may enter into an energy conservation construction contract, on the terms it determines are in the best interests of the California State University if they find that the anticipated cost for the alterations effected by the energy conservation construction contract will be less than the anticipated marginal cost to the California State University of energy that would have been consumed by the California State University in the absence of those alterations. The letting of contracts pursuant to this section shall be conducted through competitive means.
