If Missouri began implementing the 2009 IECC and Standard 90.1-2007 statewide in 2011, businesses and homeowners would save an estimated $99 million annually by 2020 and $200 million annually by 2030 in energy costs (assuming 2006 prices).
Additionally, implementing the latest model codes would help avoid about 31 trillion Btu of primary annual energy use by 2030 and annual emissions of more than 2.1 million metric tons of CO2 by 2030.
A 2010 BCAP analysis indicates that the weighted average incremental construction cost of upgrading to the 2009 IECC in Missouri would be $875.28 per home. On average, the annual energy savings per home would be $459.00, meaning the simple payback for homeowners would occur, on average, in 1.91 years. These estimates are conservative and represent the upper bound on incremental cost.

Missouri Minimum Energy Efficiency
Standards For State Buildings
Intro/Brief:
-
During the summer of 2008, the state of Missouri passed a wide-ranging package of energy efficiency initiatives, including homeowner tax incentives and minimum energy standards for state buildings. Passed in the state legislature on May 29 and signed by then-Governor Matt Blunt on July 10, the bill (SB 1181) required the Department of Natural Resources to establish minimum energy efficiency standards for state buildings, based on the 2006 IECC. The Commissioner of the Office of Administration may exempt any state building from meeting the minimum energy efficiency standard requirement for safety reasons or when the cost of compliance is expected to exceed the energy cost savings.
Citation: SECTIONS 8.295 - 8.837 - STATE BUILDINGS
Application: Applies to all new and renovated state-owned construction.
Approximate Stringency: As stringent as the 2006 IECC.
Effective Date: July 1, 2009
Background:
In response to legislation signed in 1993, for Energy Efficiency in State Facilities, a rule was finalized and published on January 26, 1996, with an effective date 30 days later that established "state building minimum efficiency standards." The rule covered new state buildings (or portions), additions, substantial renovations, or existing buildings considered for lease (when over 10,000 sq. ft.) or acquisition by the state. ASHRAE/IESNA 90.1-1989 was adopted by reference for buildings other than single-family and multi-family residential buildings not over three stories high. For single-family and multi-family residential buildings, the latest editions of the Council of American Building Officials Model Energy Code (MEC) or ANSI/ASHRAE Standard 90.2-1993 was applicable. New editions/revisions to these adopted standards would automatically be adopted by reference and become effective three months after the date of their publication. (10 CSR 140-7, Department of Natural Resources.) No statewide requirements existed for other buildings; local cities and jurisdictions adopt their own requirements.

Due to its history of strong local government, Missouri does not have a mandatory statewide energy code. However, however all local jurisdictions except class III counties have the right to adopt an energy code. As expected, this system creates a sometimes confusing patchwork of different codes throughout the state. Seethis page or see below for more details on local adoption.
Regardless of the system in place, the bottom line is that many jurisdictions in Missouri still don't have an energy code—meaning that many residents do not receive the benefits of energy-efficient construction.
Missouri has considered adopting a state code previously. For example, SB 745, drafted by BCAP in 2010, would have adopted the 2009 IECC and ASHRAE Standard 90.1-2007 statewide. It also would have directed DNR to establish an automatic review cycle, either every three years or within nine months of the publication of a new model code version. In addition, HB 938 in 2011 would have established most of the 2006 International Code series as minimum statewide construction standards (the 2006 IECC was not specifically cited, but would have been included via its position as an alternative compliance path to Chapter 11 of the 2006 International Residential Code). Both bills, however, failed to move past the committee stage.

All local jurisdictions except class III counties have the right to adopt an energy code. As expected, this system creates a sometimes confusing patchwork of different codes throughout the state.
It is typical for Missouri communities to adopt codes on a 6-year cycle rather than the 3-year code development cycle for ICC. It is also typical for communities to follow the code adoption of surrounding communities. These adoption practices have developed two trends in Missouri; eastern Missouri communities are generally on the 2003 I-Codes and are moving/have moved to the 2009 I-Codes and western Missouri communities are generally on the 2006 I-Codes and are moving to the 2012 I-Codes.

Code Change Process:
Legislative: In Missouri, only the General Assembly is authorized to enact legislation to establish statewide building construction regulations and/or authorize a state agency to do so. However, there currently is no state regulatory agency authorized to promulgate, adopt, or update construction codes on a statewide basis.
