Its a great tool to help you get a grasp of your facilities energy profile and the potential for your building to become more energy efficient. The objective of an energy audit is to qualify and quantify how a building’s energy using systems are performing, what is required to improve efficiency, and what will be the benefits of the improvements .
These audits can vary scope depending on a number of characteristics of a building and it usually is not entirely possible to know where the audit process will lead, or what level of effort will be most cost effective.
The American Society of Heating, Refrigerating and Air-Conditioning Engineers
has defined three levels, of audits. They are usually performed in sequence and the primary determining factor on what level audits are performed is based on the potential and desire for energy savings, building performance, available funding and the relative return on investment.
