Model Energy & Green Codes
NBI works collaboratively with a wide range of industry partners to bring model codes up to current market capabilities. NBI also works with jurisdictions and utilities to advance higher efficiency standards through stretch codes and voluntary utility programs Once adopted by states and local jurisdictions, the model code becomes the basis for minimum energy requirements.
International Energy Conservation Code (IECC)
In October 2010, local code officials from across the country approved comprehensive changes to the 2012 International Energy Conservation Code (IECC). The changes proposed by NBI, along with the U.S. Department of Energy and the American Institute of Architects, were largely based on NBI’s Core Performance Guide and represent the largest single-step efficiency increase in the history of the IECC. When adopted by a jurisdiction, the 2012 IECC results in buildings that are 20-30% more energy efficient than current practice (ASHRAE 90.1 2004). Read More
International Green Construction Code (IgCC)
NBI is involved in the International Code Council’s efforts to create a new green overlay code intended for more advanced jurisdictions and institutions. Known as the International Green Construction Code (IgCC), the IgCC provides an opportunityfor communities to adopt energy codes that are more advanced and holistic than the base IECC code or ASHRAE Standard 90.1.

Other Model Codes & Resources
Both the American Society of Heating, Refrigeration and Air Conditioning Engineers (ASHRAE) and the state of California have developed model energy and green codes that states and municipalities can consider when developing local codes. In addition, there are a number of other resources available to help with code development.
- ANSI/ASHRAE/USGBC/IES Standard 189.1
- CalGreen
- Online Code Environment and Advocacy Network (OCEAN) supports stakeholders in adopting and implementing building energy codes.
- U.S. Department of Energy Building Codes Program offers an interactive map that shows what model code a particular state has adopted.
- BCAP’s national listing of voluntary and mandatory above code, high performance, and green building programs (August 2009)
