This Industrial Technologies Program case study describes an energy assessment team's recommendations for saving $5 million in energy, water, and other costs at an oil refinery in Houston, Texas.

The Bayer Corporation undertook a plant-wide energy efficiency assessment of its New Martinsville, West Virginia, plant in 2001. The objectives were to identify energy saving projects in the utilities area. The projects, when complete, will save the company the loss of an estimated 236,000 MMBtu ($1.16 million) annually in energy from burning and leaking fossil fuels. Certain other projects will save the company 6,300,000 kWh ($219,000) of electrical energy each year. All of the projects could be duplicated in other chemical manufacturing facilities and most of the projects could be duplicated in other industries utilizing steam, pumps, and/or compressed air.

This OIT BestPractices case study describes the methods and results of a plant-wide energy assessment at Metlab's aircraft component manufacturing plant in Wyndmoor, PA. Recommendations derived from the assessment, if implemented, can save an estimated $528,400 annually, reduce natural gas use by 50,070 MMbtu per year, and reduce electrical use by 329,400 kWh per year.
