Midwest Energy Codes Status Report - April 10, 2015

Midwest Energy Codes Status Report
April 10, 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.  The residential sub-committee has recently made some changes to their recommendations, and will bring the following proposals to the full committee on April 20th:
    • 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
    • Providing two options for basement insulation:
      • Reducing basement insulation requirement to R-10/13 at full depth (6 inches from floor).
      • Insulating only 4 feet from top of basement wall at R – 15/19
    • Incorporating the Energy Rating Index (R406) as an approved Alternative Design under section R102.  Additional language would exclude the ERI from the state’s code training curriculum.

Please contact Matthew Giudice at MEEA with any questions, mgiudice@mwalliance.org.

  • 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


  • There is language in the recently introduced Omnibus bill in the State legislature that would affect future code adoption in the state.  The relevant language can be found on pages 70 – 72 of the bill, which can be found under “Committee Documents.”

The language is expected to change, but as it currently stands could have the following effects:

  • Introduce a six year code cycle for all non-energy building codes, starting with 2018
  • Reinforce the federal requirements that the state would have to review the model energy codes after they are published and determine whether adoption is appropriate for Minnesota.
  • Require the state to adopt an Energy Rating Index compliance path for the current residential energy code, based on the 2012 IECC

MEEA is working with others to evaluate and comment on the above proposals.  One specific comment that MEEA has expressed is the opposition to incorporating specific code requirements using an omnibus bill in the state legislature.  We feel that adoption of an ERI, or other substantive code changes, should take place through the existing administrative rulemaking process, in order to allow an opportunity for expert input and a thorough examination of future impact on efficiency.

Please contact Matthew Giudice at MEEA for more information, mgiudice@mwalliance.org.


  • A bill has been introduced in the Nebraska legislature that would allow for the state to study the 2012 and 2015 versions of the IECC, which would result in recommendations for whether either should be adopted statewide.  Nebraska currently has a statewide version of the 2009 IECC, effective for residential and commercial buildings.

A copy of the recently introduced bill, LR 174, can be found here.
