13、pplication of ASME EA-4, Energy Assessment for Compressed Air Systems. This guidance document provides background and supporting information to assist in carrying out the standard. The guidance document covers such topics as rationale for the technical requirements of the assessment standard; techni

14、cal guidance, application notes, alternative approaches, tips, techniques, and rules-of-thumb; and example results from fulfilling the requirements of the assessment standard. This guidance document was developed to be used as an application guide on how to utilize ASME EA-4.ASME EA-4 provides a sta

15、ndardized framework for conducting an assessment of compressed air systems. A com-pressed air system is defined as a group of subsystems composed of integrated sets of components used to deliver compressed air energy to manufacturing equipment and processes. Assessments performed using the requireme

16、nts set by ASME EA-4 involve collecting and analyzing system design, operation, energy use, and performance data and iden-tifying energy performance improvement opportunities for system optimization. These assessments may also include additional information, such as recommendations for improving res

17、ource utilization, reducing per unit production cost, and improving environmental performance of the assessed system(s). ASME EA-4 provides a common definition for what constitutes an assessment for both users and providers of assess-ment services. The objective is to provide clarity for these types

18、 of services that have been variously described as energy assessments, energy audits, energy surveys, and energy studies. In all cases, systems (energy-using logical groups of industrial equipment organized to perform a specific function) are analyzed through various techniques such as measurement,

19、resulting in the identification, documentation, and prioritization of energy performance improvement opportunities. This Guide is part of a portfolio of documents and other efforts designed to improve the energy efficiency of indus-trial facilities. Initially, assessment standards and guidance docum

20、ents are being developed for compressed air, process heating, pumping, and steam systems. Other related existing and planned efforts to improve the efficiency of industrial facilities include(a) ASME assessment standards, which set the requirements for conducting and reporting the results of a com-p

21、ressed air, process heating, pumping, and steam assessments.(b) a certification program for each ASME assessment standard that recognizes certified practitioners as individu-als who have demonstrated, via a professional qualifying exam, that they have the necessary knowledge and skills to apply the

22、assessment standard properly.(c) an energy management standard, A Management System for Energy, ANSI/MSE 2000:2008, which is a stand-ardized approach to managing energy supply, demand, reliability, purchase, storage, use, and disposal and is used to control and reduce an organizations energy costs a

23、nd energy-related environmental impact.NOTE: ANSI/MSE 2000:2008 will eventually be superseded by ISO 50001, now under development.(d) an ANSI measurement and verification protocol that includes methodologies for verifying the results of energy efficiency projects.(e) a program, Superior Energy Perfo

24、rmance, that will offer an ANSI-accredited certification for energy efficiency through application of ANSI/MSE 2000:2008 and documentation of a specified improvement in energy performance using the ANSI measurement and verification protocol. Superior Energy Performance is now using the ISO Draft Int

25、ernational Standard 50001 for plants. ISO 50001 is not yet final. The Measurement and Verification Protocol is anticipated to be a normative reference to ANSI/MSE 50021 and ANSI/MSE 50028.The complementary documents described above, when used together, will assist organizations seeking to establish

26、and implement company-wide or site-wide energy plans.Publication of this Technical Report that has been registered with ANSI on July 27, 2010 has been approved by ASME. This document is registered as a Technical Report according to the Procedures for the Registration of Technical Reports with ANSI.
