Join the Coalition 

Led by ACEEE, the Next Generation Codes Coalition comprises the states of California, Colorado, Maryland, Massachusetts, New York, and Washington, as well as the City of Seattle, Enterprise Community Partners, the National Association of State Energy Officials, and the New Buildings Institute. To learn more or join the Coalition, please contact Steve Nadel.

The Next Generation Codes Coalition supports states and local jurisdictions in improving residential energy codes that significantly lower residents’ energy bills, reduce water use and air pollution, and improve comfort, health, and affordability. 

Today many leading jurisdictions are seeking options for codes as they work to improve affordability and increase housing supply. The Next Generation Codes Coalition is providing a path forward, building on the decades of residential energy codes developed by the International Code Council. 

The Coalition is developing amendments to the International Energy Conservation Code. These amendments are designed for state and local jurisdiction use and for use by programs promoting voluntary improvements beyond base codes. The Coalition will also research and publish strategies that can help jurisdictions address affordability and increase housing supply. Topics will include improving housing affordability through voluntary programs and code development and implementation, streamlining compliance approvals, developing the workforce to build next generation homes, and implementing next generation codes.
