It is common for energy audits to give little effort or attention to operations and maintenance (O&M) and other low cost measures - and to jump immediately to replacing equipment - but doing so is not a thorough scope of review for energy improvement. There are many opportunities to save energy and money with existing systems without replacing equipment. A culture of controlling energy use with operations optimization and targeted maintenance allows facilities to make the most of what they have. Most O&M measures require no business case because they are low cost. Savings associated with O&M involve specific service activities, repairs, and operating strategies. Measures that result in using less to begin with can stand alone or can be combined with capital projects to amplify savings and downsize the new equipment. Equipment replacement projects that involve only the source equipment and do not incorporate measures to first optimize end use will result in project savings that are less than their potential.
