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.

Benefits of Building Energy Codes
Since 2009, energy codes have saved Midwest residents more than half a billion dollars on their utility bills and reduced emissions by 3 million tons of CO2 equivalent.
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.
