ABSTRACT
The first step in developing an energy centered maintenance strategy is the identification of all energy-related systems and all energy critical equipment that should be included in the maintenance strategy of the facility. Energy classification is defined as the process of identifying the equipment’s energy impact and criticality to the facility operation. In-depth analysis must be performed for significantly energy consuming equipment before starting energy centered maintenance model and efficiency improvement. The energy classification code reflects the criticality of equipment on building energy use; a high energy classification code indicates high energy consumption equipment. Consider a facility that is served by multiple mechanical types of equipment, and the maintenance personnel and energy managers should be able to calculate the energy classification code for each piece of equipment to decide whether this equipment should be part of energy centered maintenance model or not.
