Full title and description

STB BS EN 16247-3:2022 — Energy audits — Part 3: Processes. European standard specifying requirements, methodology and deliverables for performing energy audits focused on industrial or service processes (production lines, utilities, laboratories, packaging, warehouses and associated on‑site transport and offices). It is intended to be used together with EN 16247‑1 (general requirements) and, where relevant, with EN 16247‑2 (buildings) and EN 16247‑4 (transport).

Abstract

Part 3 of the EN 16247 series provides process‑sector guidance for organising and conducting energy audits: preliminary contact and start‑up, data collection and verification, measurement plan and permitted sampling methods, field work and site visits, analysis (energy balances, energy performance indicators) and reporting (including identification and evaluation of Energy Performance Improvement Actions). The 2022 edition updates terms and structure, allows sampling methods, and adds examples for multi‑site sampling.

General information

• Publication date: 2022 (CEN approval July 3, 2022; EN publication/August–October 2022 in national catalogs — national effective dates vary by member body).
• Publisher: European Committee for Standardization (CEN); adopted and published nationally by CEN members (examples: BSI as BS EN, national bodies’ catalogues).
• ICS / categories: 03.120.10 (Quality management and quality assurance); 27.015 (Energy efficiency / energy conservation).
• Edition / version: 1st edition of EN 16247‑3:2022 (revokes/supersedes EN 16247‑3:2014).
• Number of pages: Typically published in the range of ~27–30 pages depending on national pdf formatting (commercial catalogues list 27 pages or 30 pages).

Scope

Specifies the requirements, methodology and deliverables of an energy audit where a significant portion of energy use arises from processes. Covers organising and conducting an audit, analysing process energy data (energy balances, breakdowns and EPIs), planning and performing measurements (including representative sampling), and preparing the final report with identified Energy Performance Improvement Actions. It is supplementary to EN 16247‑1 and intended to be applied simultaneously with Part 1; Parts 2 and 4 may be applied when buildings or on‑site transport are in scope.

Key topics and requirements

• Audit process: preliminary contact, start‑up meeting, data request and review, measurement planning, field work, analysis and final meeting/report.
• Measurement plan and sampling: guidance for designing measurements, allowed use of representative sampling methods for processes and multi‑site audits (Annexes provide examples).
• Analysis deliverables: energy balance and breakdown by process and utility, Energy Performance Indicators (EPIs), and identification and evaluation of Energy Performance Improvement Actions (EPIAs).
• Quality and competence: requirements for audit quality and reference to competence criteria (see EN 16247‑5 for auditor competence).
• Reporting requirements: minimum content and clarity on whether Parts 2 and/or 4 were applied; documentation of assumptions, sampling and measurement methodology.

Typical use and users

Used by energy managers, sustainability teams and facilities/operations managers in manufacturing and process industries (chemical, food, pharmaceutical, metals, etc.), energy audit consultants and certified auditors, and organisations integrating audits with energy management systems (e.g., ISO 50001). Typical applications include process energy benchmarking, prioritising efficiency projects, and providing technical evidence for regulatory or voluntary audit obligations.

FAQ

Q: What is this standard?

A: EN 16247‑3:2022 is the European standard that defines how to carry out energy audits focused on processes (industrial and process‑intensive sites), specifying required steps, measurements, analysis and reporting.

Q: What does it cover?

A: It covers organizing and conducting process energy audits, data collection and verification, measurement planning (including sampling), field work, analysis (energy balances, EPIs) and reporting including identification and evaluation of improvement actions. It is to be used alongside EN 16247‑1.

Q: Who typically uses it?

A: Energy managers, audit consultants, certified energy auditors, facilities and operations managers in process industries, and organisations aligning audits with energy management systems.

Q: Is it current or superseded?

A: The 2022 edition (EN 16247‑3:2022) is the current edition and supersedes EN 16247‑3:2014. National adoption dates in CEN member bodies occurred through 2022 (effective dates vary by country).

Q: Is it part of a series?

A: Yes — it is Part 3 of the EN 16247 series (Parts 1–5) covering general requirements, buildings, processes, transport and auditor competence.

Q: What are the key keywords?

A: Energy audit, processes, measurement plan, sampling, energy balance, EPI, EPIA, audit reporting.
