Midwest Energy Codes Status Report
June 13, 2014

Building Energy Codes Activity


The Minnesota Department of Labor and Industry (DLI) is moving closer to finalizing adoption of a new residential building energy code.  The code is based on the 2012 IECC and contains several amendments that were developed during a stakeholder process that began in 2012.

Although the public comment period is over, and the state does not anticipate further opposition to the code, there are several more procedural steps that must be completed as part of the administrative rulemaking process.  Once the code is published in the state register, it will become effective 180 days later, which we expect to be early 2015.

Below are the anticipated modifications to the model version of the residential 2012 IECC:

  1. Wall Insulation (prescriptive table only):

  • Climate zone 6: R-20 or R-13 + 5

  • Climate zone 7: R-21

  1. Basement Insulation:

    • R-15 continuous, with minimum R-10 exterior

    • Additional requirements for walk-out basements

    • R-10 continuous exterior insulation if tested air leakage rate < 2.6 ACH50

  2. Duct Insulation: Vapor retarder required for unconditioned spaces

  3. Specific requirements for basement moisture mitigation

  4.  Specific ventilation requirements (only allows balanced)

  • The Illinois Capital Development Board has begun the process to update the statewide building energy code to the 2015 IECC.  The state’s Energy Codes Advisory Council has convened several times to begin preliminary adoption work.  The group plans to begin accepting proposed amendments to the model version of the 2015 IECC in July, 2014.  More information will be released this month by the state on this effort.  For more information, please contact Matthew Giudice at MEEA, mgiudice@mwalliance.org.


  • The Nebraska Energy Code Compliance Collaborative will be holding their next meeting on June 18, 2014 in Lincoln, Nebraska.  As part of a related initiative, the state recently completed a commercial energy code compliance study.  The results of that effort will be discussed at the June 18 meeting, with presentations by those that worked on the study, including Eric Makela of Britt Makela Group, and Tim Hemsath and Brad Cory from University of Nebraska-Lincoln.  For more information please contact Chris Burgess at MEEA, cburgess@mwalliance.org.

Midwest Building Energy Codes and Benchmarking Conference:

  • MEEA will be hosting the 5th Annual Midwest Building Energy Codes & Benchmarking Conference in Kansas City, Missouri, November 18 – 20, 2014.  The first day will be dedicated to benchmarking issues, and the second and third days will focus on energy codes.  The codes sessions will include discussions on current topics, including: utility claimed savings compliance efforts, 2015 IECC, HERS and the code, and other issues related to adoption and compliance of codes in the Midwest.  The event will be held at Crowne Plaza Kansas City Downtown.  Please contact Matthew Giudice at MEEA for more information or to be added to the conference distribution list: mgiudice@mwalliance.org.
