ISO 50001 Energy Management System

ISO 50001 is a newly developed international standard for an energy management system (EnMS). ISO 50001:2011 provides a framework for establishing energy management best practice to help organisations to improve their energy efficiency in a logical, controlled and systematic way.

ISO 50001 has been structured to align with other popular industry management system standards such as those for quality, health & safety and environmental management. Organisations can thus, if appropriate, integrate an energy management system (EnMS) with their existing management system(s).

How to establish an ISO 50001 Energy Management System?

To meet the requirements of ISO 50001 an organisation must;

  • Implement and maintain a process to identify and quantify an organisation’s activities that use energy and assess their current energy profile and baseline of performance
  • Establish a specific energy policy with clear objectives and a programme to achieve these
  • Ensure document and record control
  • Maintain processes to ensure applicable legislation is identified, communicated within and compliance assessed
  • Resource roles and responsibilities with regard to direct and indirect energy usage within the organisation
  • Maintain good operational control in relation to energy usage and future consumption
  • Monitor and measure the energy management systems performance as well as energy usage and related factors
  • Apply energy management principles across all functions, from design, procurement through to operations.
  • Audit the system and review the system at a management level periodically

The benefits of ISO 50001 Certification

By achieving certification to ISO 50001 your organisation will be able to reap numerous benefits. These include and are not limited to:

  • Energy Cost Savings
  • Reduced Greenhouse-Gas Emissions and Carbon Footprint
  • Increased Energy Awareness among Staff
  • Greater knowledge of Equipment Efficiencies
  • Informed decision-making processes from system design through to operation
  • Structured approach to the Right First Time methodologies
  • Improved corporate image and credibility among stake holders, regulators, customers, prospective clients and the public
  • Improved operational efficiencies
  • Improved maintenance practices

An organisation that cannot control its energy consumption cannot control its future.

The Process

ISO 50001 is involves a two stage audit process.

  • ISO 50001 Stage 1 (Pre-Certification Audit)
  • ISO 50001 Stage 2 (Certification Audit)

The ISO 50001 Stage 1 Pre-Certification Assessment involves the organisation’s system being audited by Certified Energy System auditors to ensure the ISO 50001 meets the minimum requirements of the ISO 50001 standard.

The ISO 50001 Stage 2 Certification Assessment involves a close out of issues raised in the first ISO 50001 audit and requires the audit team to dig deeper into a company’s energy management system.


The structure of ISO 50001 is designed according to other ISO management system standards, in particular ISO 9001 (Quality Management Systems) and ISO 14001 (Environmental Management Systems). Since all three management systems are based on the PDCA cycle, ISO 50001 can be integrated easily to these systems.

There are seven major components to ISO 50001:

  • General Requirements:
  • Management Responsibility
  • Energy Policy
  • Energy Action Plan
  • Implementation and Operation
  • Performance Audits
  • Management Review


ISO 50001 provides a framework of requirements that help organizations to:

  • Develop a policy for more efficient use of energy
  • Fix targets and objectives to meet the policy
  • Use data to better understand and make decisions concerning energy use and consumption
  • Measure the results
  • Review the effectiveness of the policy and
  • Continually improve energy management.

ISO 50001 focuses on a continual improvement process to achieve the objectives related to the environmental performance of an organization (enterprise, service provider, administration, etc.). The process follows a plan – do – check – act approach.



The overall responsibility for the installed energy management system must be located with the top management. An energy officer and an energy team should be appointed. Furthermore the organization has to formulate the energy policy in form of a written statement which contains the intent and direction of energy policy. Energy policy must be communicated within the organization. The energy team is the connection between management and employees. In this phase the organization has to identify the significant energy uses and prioritize the opportunities for energy performance improvement.


The stated objectives and processes are now introduced and implemented. Resources are made available and responsibilities determined. Make sure that employees and other participants are aware of and capable of carrying out their energy management responsibilities. The realization the energy management system starts.


An energy management system requires a process for compliance and valuation of energy-related regulations. Internal audit can help to verify that the energy management system is functioning properly and generating the planned results. The processes are monitored with regard to legal and other requirements (customer requirements, internal policies) as well as to the objectives of the energy management of the organization. The results are documented and reported to top management.


The top management prepares a written valuation based on the internal audit. This document is called the management review. The results will be evaluated on their performance level. If necessary, corrective or preventive actions can be initiated. Energy-relevant processes are optimized and new strategic goals are derived.
