Full title and description

St ASME EA-2G-2010 (2015) — Guidance for ASME EA-2, Energy Assessment for Pumping Systems. This guidance document provides an application guide, background, and supporting information to assist users in applying the ASME EA-2 standard for conducting energy assessments of industrial and facility pumping systems.

Abstract

EA-2G offers practical guidance on organizing and performing pumping-system energy assessments: how to plan an assessment, collect and analyse field data, evaluate system performance, and report findings. It complements the normative EA-2 standard by giving examples, procedures, worksheets and non‑mandatory appendices to support consistent, actionable assessments.

Scope

This guidance document explains how to apply ASME EA-2 (Energy Assessment for Pumping Systems) across open and closed-loop industrial pumping systems. It addresses organization of the assessment team, defining objectives and boundaries, levels of assessment, recommended measurements and instrumentation, data analysis techniques, and reporting/documentation practices. EA-2G is intended to be used alongside EA-2 to increase the quantity and quality of energy assessments and to help identify and evaluate opportunities to improve pumping system energy performance.

Key topics and requirements

• Overview of pumping systems and typical components (pumps, drivers, piping, valves, seals, controls, instrumentation).
• How to organize and staff an assessment team (roles, authority, communications, access to data).
• Assessment planning: objectives, scope, boundaries, scheduling, and prescreening.
• Conducting field assessments: recommended measurements, instrumentation, measurement points and procedures.
• Data analysis methods for estimating energy use, identifying losses, and quantifying potential savings.
• Levels of assessment (screening, level 1/2 assessments) and criteria for deeper analysis.
• Reporting and documentation: recommended content, worksheets, and non‑mandatory appendices (references, glossary).
• Guidance on translating assessment findings into recommended actions and implementation considerations.

Typical use and users

Used by energy managers, facility and plant engineers, maintenance managers, sustainability or EHS staff, energy consultants, and auditors performing energy assessments of pumping systems in industrial, commercial, municipal water/wastewater and institutional facilities. The guidance supports both internal assessment teams and third‑party consultants.

Related standards

Primary normative reference: ASME EA-2 (Energy Assessment for Pumping Systems). EA-2G is part of the ASME EA family of standards (EA-1 through EA-4 and their guidance documents). In later developments the EA-2 family has been harmonized with ISO/ASME work on pump system energy assessment — see ISO/ASME 14414:2019 (Pump system energy assessment). Other related technical publications include Hydraulic Institute guidance and industry pump standards addressing testing, selection and efficiency evaluation.

FAQ

Q: What is this standard?

A: EA-2G is a guidance document published by ASME titled "Guidance for ASME EA-2, Energy Assessment for Pumping Systems" (2010 edition, reaffirmed 2015). It provides applied guidance to help users implement the EA-2 assessment standard.

Q: What does it cover?

A: It covers planning and organizing pumping-system energy assessments, recommended measurement and data-collection methods, analysis techniques, levels of assessment, and reporting templates and appendices to support consistent, actionable assessments.

Q: Who typically uses it?

A: Energy managers, plant/facility engineers, maintenance managers, energy auditors and consultants, and other professionals responsible for assessing and improving pump-system energy performance.

Q: Is it current or superseded?

A: EA-2G (2010, reaffirmed 2015) remains an active guidance document as published by ASME. Note: the companion normative EA-2 standard has been superseded in scope by the harmonized ISO/ASME publication ISO/ASME 14414:2019 for pump-system energy assessment; users should consult ISO/ASME 14414:2019 for the latest normative assessment requirements while continuing to use EA-2G as practical guidance.

Q: Is it part of a series?

A: Yes. EA-2G is part of the ASME EA series (EA-1 through EA-4 and their guidance documents EA-1G, EA-2G, EA-3G, EA-4G), which together address energy-assessment methods for common industrial systems (process heating, pumping, steam and compressed air systems).

Q: What are the key keywords?

A: Pumping systems, energy assessment, energy efficiency, ASME EA-2, guidance, measurement, data analysis, reporting, prescreening.
