A facility may be a residence a commercial building an industrial plant or other installation where energy is consumed for any purpose. Energy management is the practice of organizing financial and technical resources and personnel to increase the efficiency with which energy is used in a facility. Energy management typically involves the keeping of records on energy consumption and equipment performance optimization of operating practices regular adjustment of equipment and replacement or modification of inefficient equipment and systems. Energy auditing is a part of an energy management program. The auditor usually someone not regularly associated with the facility reviews operating practices and evaluates energy using equipment in the facility in order to develop recommendations for improvement. An energy audit can be and often is undertaken when no formal energy management program exists. In simple facilities particularly residences a formal program is impractical and informal procedures are sufficient to alter operating practices and make simple improvements such as the addition of insulation. In more complex facilities the absence of a formal energy management program is usually a serious
