Cal. Educ. Code § 81661

In determining the lowest responsible bidder for an energy management system pursuant to Section 20651 of the Public Contract Code, the governing board of any community college district shall consider the net cost or savings of each system. For the purposes of this section, “net cost or savings” means the cost of the system to the district, if any, less the projected energy savings to be realized from the energy management system. The governing board may require an independent evaluation of the projected energy savings.
