The Industrial Assessment Centers have existed for 42 years with an objective of teaching students how to assess energy in manufacturing facilities while providing in-field training by doing assessments. A database exists of the recommendations resulting from these assessments and their consequently implementation. This presentation gives an overview of the IACs and the results of data-mining the recommendations made in over 17,000 assessments. Results are presented for the fraction of total energy costs in gas and electricity use and demand; the most common recommendations grouped by industry NIACS classifications, the most common implemented recommendations; and typical payback periods.
