Application: Mandatory citywide. The department of City Planning and Development is charged with the enforcement of this chapter.
Approximate Stringency: less stringent than the 2012 IECC and ASHRAE 90.1-2010, but more stringent than the 2009 IECC and ASHRAE 90.1-2007. The package achieves a roughly 20% improvement above the 2006 IECC.
Effective Date: June 3, 2012, but compliance is not mandatory until October 1, 2012
Background: On May 24, 2012, the City Council of Kansas City, Missouri approved, and the Mayor signed, an ordinance adopting a package of the 2012 ICC code series, including an amended version of the 2012 IECC for residential and commercial construction. Both codes are less stringent than the 2012 IECC and ASHRAE 90.1-2010, but more stringent than the 2009 IECC and ASHRAE 90.1-2007. The package achieves a roughly 20% improvement above the 2006 IECC. While the new code is effective June 3, 2012, mandatory compliance will not begin until October 1, 2012.
The new code puts approximately 1/3 of the Kansas City metro area population under an improved, consistent energy code. Other municipalities, including Overland Park, Kansas, have also been reviewing similar code update proposals. Missouri does not adopt any statewide construction codes.
Residential code improvements:
Basement Wall Insulation Required (previously, finished basements were exempt)
- All ducts must be in conditioned space or tested
- Air infiltration requirement at 5 ACH50, a testing protocol will be developed
- Window requirements improved to U-0.35 and SHGC of 0.4 (Previously U-factor was at 0.40 and there was no SHGC requirement
- Ceiling insulation increased to R-49 from R-38
- Hot water piping insulation increased to R-3
- Duct insulation improved to 2012 IECC levels
Residential requirements that were not improved from the current code:
- Lighting requirement not included
- Above grade wall insulation not changed
- Cavities can still be used as duct returns
- Insulation for slab on grade floors not included
