A Code is A Code is A Code...
A Model Goes International

The International Energy Conservation Code, or IECC, is the successor to the Model Energy Code, or MEC. The Model Code was developed by a number of building code organizations and used as a basis for many state and local energy conservation building codes from 1983 to 1995. The International Code Council now maintains the nation's primary model energy code, which has been renamed the IECC.

The code was developed with the goal of conserving energy without unnecessarily increasing construction costs,restricting the use of new materials, products or methods of construction, or giving preferential treatment to particular types of materials, products or methods of construction. It may be adopted and enforced by a local or state jurisdiction. The code is updated regularly based on comments from code officials and other interested parties.

The 1998 IECC code requirements are essentially the same as the 1995 MEC. Explanatory material has been added to clarify some requirements. As with the MEC, the ASHRAE/IES 90.1 Code is adopted by reference to govern commercial construction. A new Chapter 7 has been added
to simplify requirements for smaller commercial buildings.

Although Nebraska law still references the 1983 Model Energy Code in areas where a more stringent local code has not been adopted, the 1983 code requirements are so minimal that standard construction practices have made the code obsolete. The Energy Office uses the 1995 Model Energy Code as the basis for reduced interest-rate mortgages and other incentives for energy efficient construction.

The IECC is available from Kirk Conger in the Nebraska Energy Office at no cost. [Note: As of December 2002, copies of the IECC are not available from the Energy Office] It may also be ordered from BOCA International at 800-214-4321, extension 720 for $25.
