Stretch Energy Code - Information The Stretch Energy Code was added to the building code on July 24, 2009 and is located in the code as Appendix 115 AA. It uses provisions of the International Energy Conservation Code 2009 (IECC 2009) but provides a more energy efficient alternative to the standard energy provisions of the code that a municipality may adopt.
Note: Although the standard "non-stretch" energy provisions of the code will be based on the IECC 2012 as of July 1, 2014, the stretch code will continue to be based on amendments to the IECC2009 (and ASHRAE 90.1-2007 for large commercial buildings) until such a time as the stretch code is updated.
