Development of ENERGY STAR Energy Performance Indicators for Metal Casters
This report describes the data and statistical methods used to construct the Energy Performance Indicator (EPI) for metal casting plants. It also explains how the EPIs were developed to provide a plant-level indicator of energy efficiency by working with the metal casting industry. This report is useful if you would like background information on how EPA's ENERGY STAR metal casting plant EPIs were developed. The report presents the individual equations used to develop the EPIs.
