Overview

The INTERNATIONAL ENERGY CONSERVATION CODE, 2009 Edition (IECC 2009), published by the International Code Council, when used in conjunction with these State of Arkansas Supplements and these Amendments to the Arkansas Energy Code for New Building Construction shall constitute the 2014 Arkansas Energy Code. In cases where there are differences between these "Supplements and Amendments" and the IECC 2009 Edition, these "Supplements and Amendments" shall take precedence.

Each of the following Chapters of this document associates directly with the corresponding chapters of the IECC 2009 unless otherwise noted.

Air infiltration accounts for substantial heat loss, heat gain and moisture migration in a building. Proper sealing around all doors, windows and other envelope penetrations through the walls, ceiling and foundation is as important to code compliance as are proper insulation R-values and assembly U-factors.

It is not the intention of this Code to abridge safety or health.

New buildings constructed shall comply with the provisions of this Code in a manner consistent with their obligations under Arkansas State law (see also the current version of the Arkansas Fire Prevention Code, Volume I Fire, Volume II Building).

These minimum standards shall not be construed as relieving the licensed builder or contractor of his or her responsibility for compliance with local ordinance, codes and regulations.
