The 2015 International Energy Conservation Code
For nearly two decades, successive versions of the International Energy Conservation Code (IECC) – the nation’s only federally-recognized model code – and its predecessor, the Model Energy Code, made only 1 – 2 percent gains in energy efficiency. That changed in 2009 and 2012, when the Energy Efficient Codes Coalition (EECC) brought together government and business leaders, regional energy efficiency alliances, academics, think tanks, utilities, conservation groups, utilities, low-income housing groups, and energy consumers to support a 30 percent energy efficiency boost.
In 2013, local and state public officials from across the U.S. rejected a withering campaign to roll back the historic, 30% efficiency gains from the 2009 and 2012 versions of the International Energy Conservation Code (IECC), voting to produce a 2015 IECC that is equivalent to or perhaps slightly more energy efficient than the 2012 version it updates.
- EECC helped by highlighting the 1 best and 15 worst proposals on the agenda for the 2015 IECC. A comprehensive guide to all the proposals is available here.
- The best proposal, the EECC’s RE186 (known as “Builder Flex Beyond the 2012” ), would have given builders the flexibility to choose from a menu of options to achieve 5 percent or more in energy savings after they have complied with the current prescriptive or performance paths in the 2012 IECC. The EECC is working to defeat proposals, such as RE166, which would erase much of the energy efficiency gains made in 2009 and 2012.

- The IECC may be called America’s model energy code, but it is developed by local and state officials that are the Governmental Members of the International Code Council. Please visit our Take Action page and our International Code Council (ICC) FAQ to find out how you can get involved!
