Midwest Energy Codes Status Report
February 27, 2015

Building Energy Code Activity


  • The Illinois Capital Development Board is currently overseeing a process by the Illinois Energy Conservation Advisory Council (ECAC) to adopt the 2015 IECC statewide for residential and commercial buildings.  Proposed amendments were due December 1, and two subcommittees – one for residential and one for commercial - are currently reviewing the submitted amendments.  The subcommittees will make recommendations for the full ECAC to vote on. 

The residential sub-committee has recently completed their review, and will bring the following recommendations to the full committee:

  • Incorporating ASHRAE 62.2 – 2013 into the mechanical ventilation standard
  • Making vapor barriers optional in below-grade basement walls
  • Weakening the air leakage requirement to 5 ACH50
  • Reducing basement insulation requirement to R-10/13 at full depth (6 inches from floor). The full ECAC will discuss including the amendment from the last code cycle as an additional option, which was R – 15/19 4 feet down from top of basement wall
  • Removing the Energy Rating Index (R406) as a compliance option.  National and local homebuilder associations requested that this option be available in the new code.  However, among other reasons, the committee felt this would present confusion during training on the new code.

  • The Illinois Department of Commerce & Economic Opportunity’s Office of Energy & Recycling has released the 2014-2015 energy codes training calendar.  All workshops are FREE for Illinois investor-owned utility customers, and CEU’s are available through several professional associations.  Please visit DCEO’s website for more information and schedules: http://www.illinois.gov/dceo/whyillinois/KeyIndustries/Energy/Pages/IECC.aspx

Missouri – St. Louis

  • The St Louis County Council is currently reviewing the 2015 IRC for adoption.  On February 26th the Building Code Review Committee (BCRC) held a meeting in Clayton, MO, where they discussed the energy portion of the code.  The committee received a number of proposed amendments from the Home Builders Association of St Louis and Eastern Missouri, which would significantly weaken the 2015 model code, and represent a rollback from St Louis’s current code, if accepted.  The proposed amendments included recommendations to weaken the window U-factor, wall insulation, ceiling insulation, basement insulation, air leakage, duct leakage, and lighting requirements, and to incorporate an equipment tradeoff provision into the performance path.  The amendment package is roughly equivalent to the 2006 IECC.  The committee approved many of the amendments, including removing duct testing requirements.  The next BCRC meeting will be March 12th, where they will continue reviewing the HBA proposals, including removing all requirements related to air leakage, mechanical ventilation, and lighting, as well as incorporating mechanical equipment tradeoffs into the performance compliance path.  Please contact Matthew Giudice at MEEA for more information, mgiudice@mwalliance.org.

Department of Energy National Energy Codes Conference 2015

  • The United States Department of Energy will be hosting a National Energy Codes Conference in Nashville, TN, March 24 – 26, 2015.  Registration is now open for all individuals that are interested in energy codes.  There is limited funding available for state and local government officials to attend, and those that are interested are strongly encouraged to inquire as soon as possible.  The conference website has more information and a link for registration and housing.  The MEEA codes team will see you there!
