Except as set forth in Subsection 4743.3, in solicitations and contracts for design services, the Department shall solicit contractors to design to LEED Silver standards as established by the United States Green Building Council (USGBC). Solicitations for design-build services shall also include this requirement.

In all other cases, the solicitation and contract shall require that the contractor comply with the Default Environmental Preference Standard, as defined in the PPRA, or provide an environmental certification as required by section 1101 of the PPRA.
