Miscellaneous

• Meter any unmetered utilities. Know what is normal efficient use. Track down causes of
deviations.
• Shut down spare, idling, or unneeded equipment.
• Make sure that all of the utilities to redundant areas are turned off -- including utilities like
compressed air and cooling water.
• Install automatic control to efficiently coordinate multiple air compressors, chillers, cooling tower cells, boilers, etc.
• Renegotiate utilities contracts to reflect current loads and variations.
• Consider buying utilities from neighbors, particularly to handle peaks.
• Leased space often has low-bid inefficient equipment. Consider upgrades if your lease will
continue for several more years.
• Adjust fluid temperatures within acceptable limits to minimize undesirable heat transfer in long
pipelines.
• Minimize use of flow bypasses and minimize bypass flow rates.
• Provide restriction orifices in purges (nitrogen, steam, etc.).
• Eliminate unnecessary flow measurement orifices.
• Consider alternatives to high pressure drops across valves.
• Turn off winter heat tracing that is on in summer.
