ENERGY STAR Focus on Energy Efficiency in Metalcasting

The “metalcasting focus” is a partnership between EPA’s ENERGY STAR program, the American Foundry Society, and metalcasting companies to improve energy efficiency within their operations. Tools are available here to help improve manufacturing energy efficiency, save money, and reduce greenhouse gas emissions.

Metalcasters can get started on a path of saving energy by using the ENERGY STAR Guidelines for Energy Management to build an energy management program, and then work within this metalcasting focus to learn best practices from the industry.  If you are a metalcaster who wants to get involved in your industry’s efforts to save energy, contact

Plant energy performance indicator (EPI) tools

Use the casting plant EPIs to assess how efficiently a plant uses energy, relative to similar plants in the U.S. The 1 - 100 ENERGY STAR score enables a quick understanding of how a plant is performing. Plants receiving a score of 75 or higher are eligible to earn ENERGY STAR certification

To learn more about the development of the aluminum and iron casting EPIs, read the following report:

To learn more about how EPIs are developed, how to interpret an EPI score, and how to value benchmarking view the Benchmarking Industrial Energy Performance guide.

Take the ENERGY STAR Challenge for the metalcasting industry

The American Foundry Society (AFS) and EPA are challenging metalcasters to improve the energy efficiency of their sites by 10% within 5 years or less.

The ENERGY STAR Challenge for Industry is an energy management tool that helps companies set plant energy performance improvement goals. Sites that achieve the ENERGY STAR Challenge for Industry will be recognized by the EPA for their leadership in reducing greenhouse gas emissions.  To learn more, visit the AFS website.
