What Is ISO 50001? Energy Management System Guide
Understand ISO 50001 energy management, energy baselines, performance indicators, certification and audit-planning inputs.
The purpose of ISO 50001
ISO 50001:2018 specifies requirements for an energy management system. It helps organizations use data, operational control and continual improvement to manage energy performance, including energy efficiency, energy use and consumption.
How an EnMS works
The organization identifies relevant variables and significant energy uses, establishes baselines and energy performance indicators, sets objectives, controls energy-related operations and evaluates whether performance is improving.
- Energy review and significant energy uses
- Energy baselines and performance indicators
- Operational and design controls
- Measurement, analysis and performance improvement
Who uses ISO 50001
Energy-intensive manufacturers, buildings, data centres, utilities, transport operations and public organizations are common users. Smaller organizations can also use the framework where energy performance is commercially or environmentally important.
What affects certification
Annual energy consumption, the number of energy types, significant energy uses, operating sites and the complexity of data and controls are important audit inputs. Employee numbers alone do not represent the energy complexity of the scope.
Common questions
Does ISO 50001 require solar panels?
No. It is technology-neutral and focuses on a managed process for improving energy performance.
Is ISO 50001 only for large factories?
No. Any organization can use it, although the system should be proportionate to its energy uses and opportunities.
Can ISO 50001 integrate with ISO 14001?
Yes. Shared management processes can be integrated while energy-performance requirements remain specifically addressed.
