ISO 50002-3:2025
What is ISO 50002-3:2025?
ISO 50002-3:2025 is part of the ISO 50002 series and provides guidance for conducting energy audits of processes using the framework established in ISO 50002-1. It is designed to help organizations identify energy performance improvement opportunities in industrial, commercial, and institutional processes.
This standard applies to a wide range of process types, including manufacturing, utilities, laboratories, data centres, and more. It can be used independently or alongside ISO 50002-2 (for buildings) and ISO 50001 (for energy management systems).
Why is ISO 50002-3 Important?
Processes often account for a significant portion of an organization’s energy consumption. ISO 50002-3 is important because it:
- Provides a structured methodology for auditing energy use in processes.
- Helps identify energy performance improvement actions (EPIAs).
- Supports compliance with energy efficiency regulations and sustainability goals.
- Enhances operational efficiency and reduces energy costs.
- Facilitates integration with ISO 50001 for organizations with energy management systems.
Benefits of ISO 50002-3
Implementing ISO 50002-3 offers several key benefits:
- Process-specific focus: Tailored to the unique characteristics of industrial and commercial processes.
- Detailed energy analysis: Encourages energy balance modeling, benchmarking, and performance indicator tracking.
- Actionable insights: Identifies technical, behavioral, and organizational opportunities for improvement.
- Cost and emissions reduction: Supports decarbonization and cost-effective energy use.
- Competence-based auditing: Ensures audits are conducted by professionals with relevant process expertise.
- Supports multi-site audits: Includes sampling methodology for organizations with many sites.
FAQ
Organizations with energy-intensive processes, including manufacturers, utilities, data centers, and healthcare facilities, as well as energy auditors.
ISO 50002-3 provides process-specific guidance and should be used in conjunction with ISO 50002-1, which outlines general energy audit principles.
Yes. It complements ISO 50001 by providing detailed audit guidance that supports the energy review process.
Manufacturing lines, utility systems (e.g., steam, compressed air), HVAC, sterilization, data centers, and more.
Measures identified during the audit to improve energy efficiency, reduce consumption, or optimize operations.
