Building Codes Activity
MEEA participated in the development of the 2018 International Energy Conservation Code (IECC) at the ICC Code Action hearings in Louisville, KY. There were few recommendations from the residential committee to improve the efficiency of the residential code, but the commercial committee did recommend some efficiency improvements (such as the inclusion of air leakage testing and improved lighting efficiency) to the commercial code. These are merely recommendations from the committee and the final voting will occur in October 2016 at the ICC Final Action Hearings on the 2018 IECC. For a full review of the committee recommendations, please click here.
On Monday, June 6, 2016, the Columbia City Council voted to adopt the 2015 International Energy Conservation Code (IECC) as written for residential and commercial buildings. Additionally, the Council chose to adopt the Solar-Ready Provisions (Appendix RB) as part of the 2015 IECC for residential buildings. The adoption of the 2015 IECC improves the efficiency of their previous energy codes, the 2012 IECC for residential and 2009 IECC for commercial buildings. According to the Department of Energy (DOE) Final Determinations, building to the new code will yield approximately 1% and 25% in site energy savings for residential and commercial buildings, respectively.

The Iowa Energy Code Working Group met on April 29 to discuss and vote on proposed amendments to the 2015 IECC. Of the 18 proposed amendments from stakeholders in the state, four have been deemed to have merit and will be discussed further at the next meeting. These four amendments include adopting the 2015 IECC as written, altering the HVAC system types used in the Appendix G baseline energy models in Standard 90.1-2013, improving the air leakage requirement from 4 (current Iowa Code req.) to 3.5 ACH50, and altering the ERI envelope backstop. The date of the next meeting has not yet been determined.
The Ohio Board of Building Standards (BBS) and Residential Code Advisory Committee (RCAC) are currently reviewing the 2012 and 2015 IECC commercial and residential provisions as a first step to considering state adoption. The RCAC is still reviewing the residential energy codes, but the BBS has recently released its proposed rules for the commercial energy code. The BBS recommends adopting the 2012 IECC/ASHRAE Standard 90.1 - 2010 with minor amendments, which would improve the efficiency of commercial building types by 18.5% according to a Department of Energy study. The proposed rules and business impact analysis can be reviewed here. The RCAC and BBS do not have meetings scheduled in June, but the BBS and RCAC will reconvene in July and August, respectively. An updated calendar can be found here.
On Tuesday, June 7 the Commercial Building Code Council met to continue reviewing the differences between their current commercial energy code (2009 IECC amended), and the 2012 and 2015 IECC. The council finished reviewing the codes and will likely have draft rules at the July meeting. Minutes from the June 7 meeting have not been posted yet, but all other minutes can be found on their website.
As part of the Kentucky Code Compliance Improvement Study, in-person code trainings are taking place throughout the state on the topics of Air Sealing, HVAC Design and Common Compliance Challenges. The list of upcoming classes can be found here.
Additionally, the project has created a local Circuit Rider Program in which a Kentucky energy code expert provides personalized outreach to code officials and builders across Kentucky.
The Kentucky Project Team has also created a series of training videos that encompasses what topics are covered in the 2009 IECC.
MEEA is conducting a Residential Building Energy Code Study to determine current construction practices in Missouri as it relates to the 2009 IECC. The stakeholder group for the study held a meeting in Columbia, MO on June 1 to discuss preliminary findings, and MEEA will create a final report this summer detailing the highest energy-savings opportunities for new homes across the state.
