Over the past several years, there has been growing interest among policy makers and
others in the role that benchmarking industrial energy efficiency can play in climate, air, and
other potential regulatory actives. For over ten years, the US EPA has supported the
development of sector specific industrial energy efficiency benchmarks, known as ENERGY
STAR Energy Performance Indicators (ES-EPI). To date there are ES-EPI that are either
completed or under development for fourteen broad industries. Within these industries, ES-EPI
account for over two dozen sub-sectors and many more detailed product types. Newer versions,
or updates for three of the industries' ES-EPI have been developed in recent years. Through
the process of updating this ES-EPI, the program has been able to observe changes in the energy
performance of the sector as well as the range in performance found in the sector. This paper
provides an overview of the approach that has been used in this research to develop this ES-EPI;
summarizing the industry specific and general findings regarding the range of performance
within and across industries. Observations about industrial plant benchmarking and lessons
learned will be explored. In general, there are no sectors that are easily represented by a simple
energy per widget benchmark; less energy intensive sectors tend to exhibit a wider range of
performance than energy intensive ones; changes over time in the level and range of energy
performance, i.e. industry curve shift, for ES-EPI that have been updated do not reveal any
single pattern.
