Several provisions of Missouri law govern energy efficiency in state facilities. In 1993 Missouri enacted legislation requiring life-cycle cost analysis for all new construction of state buildings and substantial renovations of existing state buildings when major energy systems are involved. Substantial renovations involve projects that will affect at least 50% of the building's square footage or cost at least 50% of its market value.

The analysis must take into account the initial construction costs and the proposed energy consumption, operation, and maintenance costs over a 25-year time horizon. The final design must have the lowest life-cycle cost possible while still meeting the building's space and use requirements. The analysis is required to examine all commercially available technology, including 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 reuse. Plans must be reviewed by the Director of the Division of Design and Construction within the Missouri Office of Administration.

In 2008 the state updated its energy code for state construction and renovations of buildings larger than 5,000 square feet. Under the new policy ([http://www.senate.mo.gov/08info/pdf-bill/tat/SB1181.pdf S.B. 1181]), the Missouri Department of Natural Resources (DNR) was required to establish energy efficiency standards for state buildings at least as stringent as the 2006 International Energy Conservation Code (IECC) by January 1, 2009. The standards apply equally to both state-leased and state-owned buildings for which the building design process or the lease begins after July 1, 2009. The Commissioner of the Office of Administration may grant waivers to these requirements if compliance is expected to exceed the energy cost gained or if the requirement would compromise safety.

Subsequent to the 2008 statutory revision described above, in April 2009 Governor Nixon issued Executive Order No. 09-18 requiring all state agencies whose building management falls under the Office of Administration to adopt policies designed to reduce energy consumption by 2% each year for the next 10 years. Similar to S.B. 1181, the order also requires that new construction projects undertaken by covered agencies use energy efficiency standards at least as stringent as the most recent version of the IECC.

History

In July 2009 the state enacted further legislation ([http://www.senate.mo.gov/09info/pdf-bill/tat/SB376.pdf S.B. 376]) requiring that appliances purchased whole or in part with state money be Energy Star compliant unless the added cost exceeds the projected energy cost savings. However, this provision expired in August 2011.
