Procurement; energy performance-based contracting. Authorizes a public body, defined as a contracting entity, to purchase energy conservation or operational efficiency measures from an energy performance-based contract entered into by another contracting entity pursuant to the Energy and Operational Efficiency Performance-Based Contracting Act even if the entity did not participate in the request for proposals if the request for proposals specified that the procurement was being conducted on behalf of other contracting entities. The measure permits the use of cooperative procurement for energy conservation or operational efficiency measures in such instances. The bill provides, however, that energy conservation or operational efficiency measures shall not include roof replacement projects.
