In accordance with the provisions of Section 304 of the Energy Conservation and Production Act (ECPA), as amended under 42 U.S.C 6833(b)(2)(B)(i) and 42 U.S.C 6833 (a)(l), each state must file certification statements to the U.S. Department of Energy (DOE) that it has reviewed the provisions of its building codes regarding energy efficiency and make a determination as to whether to update its code to meet or exceed the 2015 IECC, as well as ASHRAE 90.1-2013.

In 2010, the State of Hawaii adopted the 2006 IECC with amendments as the State Energy Conservation Code, referenced herein as the Hawaii Energy Code (HEC). The Hawaii State Energy Office has contracted with the Britt/Makela Group (BMG) team to provide analyses of proposed amendments to residential and commercial provisions of the 2015 IECC. The outcome of this analysis will be to facilitate adoption at the state and county level. In addition, the analysis provides a basis for the Hawaii State Energy Office to...

This analysis of residential energy code compares the requirements of the 2009 International Energy Conservation Code (IECC) with the residential code—or typical construction practice in the absence of a code—in most states as of June 2009. The results, which include estimated typical energy savings of updating each state’s code to the 2009 IECC, are provided in chapters specific to each state.

Several states have either not adopted a mandatory energy code or developed their own codes which have minimal or no connection to the IECC. The latter—including California, Florida, Oregon, and Washington— were not included in this analysis because the codes in these states would be difficult to appropriately compare to the 2009 IECC and most of these states have energy offices that have already assessed the IECC on their own.
