Building Energy Codes

Building energy codes contain minimum energy efficiency provisions for residential and commercial buildings. The codes are recognized as a simple and cost-effective way to reduce energy consumption and lower energy bills. Buildings consume 40% of the world's raw materials and energy. Today’s new construction buildings are estimated to have a lifetime of 75 years. It is cheaper and easier to build in energy-saving components at the time of construction, meaning that energy savings opportunities are lost over the lifetime the building if they are not added in during initial construction.

Additional Codes Resources

Because energy codes are a nationally-important issue, a number of national organizations track building energy code information across the country. Additional building energy code resources are available at:

The U.S. Department of Energy, Building Energy Codes Program

The U.S. Department of Energy (DOE), through the Building Energy Codes Program (BECP), supports energy efficiency in buildings through the development and implementation of model codes and standards. U.S. DOE also provides technical assistance to states and localities as they adopt and enforce energy codes.

The Online Code Environmental and Advocacy Network (OCEAN)

OCEAN is a project of the Building Codes Assistance Project (BCAP). It is an interactive resource designed to share experiences, best practices, educational resources, and news about building energy codes. By creating a virtual community, OCEAN enables stakeholders to discuss and learn about code issues, connect to trainers and educators, and find policies and program ideas that can serve as models.
