Energy Assessment for Pumping Systems
 N EA-2

Annotation

This Standard covers pumping systems, which are defi ned as one or more pumps and those interacting or interrelating elements that together accomplish the desired work of moving a fl uid. A pumping system thus generally includes pump(s), driver, drives, distribution piping, valves, sealing systems, controls, instrumentation, and end-use equipment such as heat exchangers. This Standard addresses open and closed-loop pumping systems typically used in industry, and is also applicable to other applications.

This Standard sets the requirements for conducting and reporting the results of a pumping system assessment (hereafter referenced as an "assessment") that considers the entire pumping system, from energy inputs to the work performed as the result of these inputs. An assessment complying with this Standard need not address each individual system component or subsystem within an industrial facility with equal weight; however, it must be suffi ciently comprehensive to identify the major effi ciency improvement opportunities for improving the overall energy performance of the system. This Standard is designed to be applied primarily at industrial facilities, but many of the concepts can be used in other facilities such as institutional, commercial, and water and wastewater facilities.

Assessments involve collecting and analyzing system design, operation, energy use, and performance data, and identifying energy performance improvement opportunities for system optimization. An assessment may also include other information, such as recommendations for improving resource utilization, reducing per unit production cost, reducing life-cycle costs, and improving environmental performance related to the assessed system(s). Assessment activities may include, but are not limited to, engaging facility personnel and providing information about the assessment process; collecting and analyzing data on system design, operation, energy use, and performance; identifying energy performance improvement opportunities; and making recommendations for system improvement and implementation in a written report. This report should document system design; quantify energy consumption and performance data; document the assessment process; show results, recommendations and savings projections; and improve facility personnel's understanding of system energy use and operation.
