Mo. Rev. Stat. § 8.810

8.810. State building construction or substantial renovation — analysis required, content — division of design and construction not to let contracts without considering — projection of energy savings required, when. — 1. In addition to all other requirements imposed by law, the director of the division shall require, for construction of a state building or substantial renovation of an existing state building when major energy systems are involved, that a design professional submit an analysis which meets the design program's space and use requirements and reflects the lowest life cycle cost possible in light of existing commercially available technology. The analysis, using existing commercially available technology, shall include, but shall not be limited to, designs which use renewable energy sources, earth-sheltered construction, systems to recover and use waste heat, thermal storage heat pump systems, ambient thermal energy, district heating and cooling systems, devices to reduce water consumption, and plumbing systems to recover gray water for appropriate reuse.

2. The director of the division shall not let a contract after January 1, 1996, for construction of a state building or substantial renovation of an existing state building when major energy systems are involved before completing an evaluation of the design documents and construction documents based upon life cycle cost factors and the minimum energy efficiency standard established in subsection 1 of section 8.812 .

3. Any design documents submitted to the division under this section shall, in addition to any other requirements under law, include a projection of the energy savings that will result from the design features that are employed in order to comply with the minimum energy efficiency standard established in subsection 1 of section 8.812 .
