||An amendment to the 2012 NC Energy Conservation Code replacing references to ASHRAE 90.1-2007 with ASHRAE 90.1-2010 becomes effective. This adoption adds a new alternative compliance path for commercial buildings; it only replaces 501.1 Item 2 as a compliance path. Other compliance pathways - 501.1 Item 1, NC specific COMcheck, and Section 507 - are still valid.1
||DOE announces North Carolina as one of eight states that will participate in a three year residential energy code field study. The other states are Alabama, Arkansas, Georgia, Kentucky, Maryland, Pennsylvania, and Texas. The study comprises three main stages: a baseline study to identify typical home energy usage; an education, training, and outreach phase; and a post-study to evaluate the change in energy use following the second phase activities. The North Carolina Energy Efficiency Alliance will help coordinate the outreach phase.2
|March 11, 2014
||The North Carolina Building Code Council votes to replace the existing three-year building code cycle with a six-year cycle for all codes besides the National Electric Code (NEC).3
||A bill to repeal the 2012 energy codes and regress to the 2009 standards passes through the House and the Senate Commerce Committee, but ultimately fails in the full Senate.
|January 1, 2012
||The 2012 North Carolina Energy Conservation Code (NCECC), based on the 2009 IECC with substantial strengthening amendments, becomes effective. ASHRAE 90.1-2007 is an acceptable compliance path through Chapter 5 of the 2009 IECC. This code will become enforceable on March 1, 2012, two months later. An analysis of the new code by Mathis Consulting identifies the major energy efficiency advancements.
|June 24, 2011
||Governor Beverly Purdue signs into law legislation that updates the NCECC. The new code achieves significant energy savings in residential and commercial buildings beyond the state’s current energy code, which is based on the 2006 IECC. This new code also includes the voluntary High Efficiency Residential Option (HERO) Appendix, which delivers a 30% improvement over the state’s current energy code.4 This alternative offers prescriptive paths that require slightly better insulation, fenestration, air sealing, equipment, and lighting packages. This development follows the introduction of SB 708 in April 2011.5
|September 14, 2010
||The North Carolina Building Code Council (NCBCC) votes 8-6 to defer any action on the adoption of the state's proposed new energy code until the next code update cycle concludes in 2015.6
|March 16, 2010
||The NCBCC votes to adopt the 2009 I-Codes, including the 2009 IECC with North Carolina amendments, as the 2012 NC State Building Codes. The product of a $500,000 competitive grant awarded by DOE in 2008, the NC amendments to the 2009 IECC are intended to achieve a 30% energy savings beyond the 2006 IECC.7
|July 1, 2009
||The 2009 NCECC, based on the 2006 (and referencing ASHRAE 90.1-2004 for commercial buildings) becomes effective. The code includes strengthening amendments to the base code, requiring fenestration U-factor and SHGC values of 0.40 across the state.
|September 9, 2008
||Governor Mike Easley announces that North Carolina is one of six states to win a federal grant to advance building codes. The other five states are California, Florida, Massachusetts, Nebraska, and Washington. The three-year, $500,000 grant is intended to develop a building energy code that results in a 30% energy efficiency improvement over the 2006 IECC, and also to improve the training of code inspectors, increase compliance, and establish an appropriate level of enforcement.8 9
|July 1, 2006
||The 2006 NCECC, based on the 2003 IECC, becomes effective.
|December 31, 2001
||The 2002 NCECC, based on the 2000 IECC, becomes effective.
||The NCBCC adopts the Southern Building Code Congress (SBCC) Standard Building Code insulating standards as statewide standards. The council later adopts the Standard Building Code with North Carolina amendments, which take effect on January 1, 1978.
