Background and
overview to the
ISO 50001:2018

The updated version of the Energy Management System ISO 50001 was published on the 21st August 2018. The standard is a framework that sets out a systematic approach for the improvement of energy performance within an organization.

Used by organizations across the world to manage and reduce energy use and costs, ISO 50001 is an excellent framework to help implement an energy management system (EnMS).

The key changes and benefits of the revised standard include:

  • A stronger emphasis on the responsibility of leadership
  • Clarification of key concepts related to energy performance
  • Improved compatibility with ISO 14001 and other ISO management system standards
  • Improved sections on data collection and normalization
  • The realignment of the content of the standard to the high level structure

Management

What is an energy management system ?

An energy management system helps organi-zations better manage their energy use, thus improving productivity. It involves developing and implementing an energy policy, setting achievable targets for energy use, and designing action plans to reach them and measure progress. This might include implementing new energy efficient technologies, reducing energy waste or improving current processes to cut energy costs.

ISO 50001 gives organizations a recognized framework for developing an effective energy management system. Like other ISO man-agement system standards, it follows the "Plan-Do-Check-Act" process for continual improvement.

ISO 50001 provides a set of requirements that enable organizations to :

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

ISO 50001:2018

Who Are EnMS For?

ISO 50001 is applicable to any organization whatever the size, industry or geographical location.

It is particularly relevant if the organization operates energy intensive processes or faces a greenhouse gas emissions challenge.

All activities and industries are concerned

  • Manufacturing (Aerospace, Automotive, Electrical, Electronics…)
  • Process industries & Mining (Chemical, Pharmacy, Metals, Paper, Cement, Glass, Wood, Oil&Gas …)
  • Power & Utilities (Energy Production, Energy and Water Distribution, Water and Waste Treatment…)
  • Food
  • Construction & Real estate
  • Transportation & Infrastructures
  • Retail
  • Services (Healthcare, Finance, Insurance, Telecom, Tourism…)
  • Government & Public organizations (Public Administration, Public sector service delegation …)

Updates and key provisions

What does the ISO 50001 look like?

Aside from the adoption ofthe High Level Structure HLS, which improves compatibility with other ISO management system standards (e.g. ISO 14001, ISO 9001, ISO 45001), the revised standard provides greater clarification of existing concepts and includes new definitions including energy performance improvement.

Most of the changes in ISO 50001:2018 vs. ISO 50001:2011 are due to the adoption ofHLS, while some are specific to energy management

PDCA
Cycle

ISO 50001:2018
Energy Management System

The Plan-Do-Check-Act (PDCA) cycle is the operating principle of ISO management standards. By following this cycle, you can effectively manage and continually improve your organization’s effectiveness.

ISO 50001 is based on the management system model of continual improvement. The standard provides a framework of requirements for 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 about energy use
  • Measure the results
  • Review how well the energy policy is working

PLAN

Establish objectives and draft your plans (analyse your organization’s current systems, establish overall objectives, set interim targets for review and develop plans to achieve them)

DO

Implement your plans within a structured management framework

ACT

Correct and improve your plans to meet and exceed your planned results

CHECK

Measure and monitor your actual results against your planned objectives

Integration with
other management systems

Link between ISO 50001:2018 and other standards

ISO 50001 is based on Annex SL –the ISO high level structure (HLS) thatbrings a common framework to all management systems. This helps tokeep consistency, align different management system standards, offer matching sub-clauses against the top-level structure and apply common language across all standards. With the new standard in place, organizations will find it easier to incorporate their energy management system into the core business processes and get more involvement from senior management

ISO 50001 can be easily linked with ISO 9001 and ISO 14001. ISO 50001 focuses on energy efficiency, whilst ISO 14001 emphasizes the significant environmental impacts of an organization. Both standards can be either individually implemented or with each other. These standards can also be integrated with other management system standards, such as ISO 9001.

In addition, other International Standards related to energy management are:

  • ISO 12655, Energy Performance of buildings
  • ISO 13153, Framework of the design process for energy saving
  • ISO/TC 180, Solar energy
  • ISO/TC 238, Solid Biofuels
  • ISO 14067, Greenhouse gas emissions
  • ISO 13790, Calculation of energy use for heating and cooling
  • ISO 18292, Energy performance of fenestration (windows) systems

How will the Energy Management Standard benefit my organization?

Implementing this standard provides a systematic way to continually improve your organization’s energy performanceand energy management system. Drawing on the knowledge and experience of energy management experts globally, the standard does not dictate what your organization’s energy targets shouldbe or how your energy performance improvement will be demonstrated. It will help you reduce your energy costs, grow more sustainably, become more resilient and comply with legislation.

Improved financial performance

  • Increases your understanding of: what types of energy you use
  • How much you are using/wasting, and; how much it's costing
  • Gives you the tools to reduce energy use and energy consumption, and/or increase energy efficiency, thus lower your energy bills and become more competitive
  • Enhances resilience by reducing your reliance on fossil fuels and energy supply

Improved business integration

  • Enables you to take a structured approach to integrating energy management into your business practice
  • Takes a business-orientated approach to identify and manage energy as a risk to the organization.

Improved compliance

  • Improves your compliance with energy legislation, regulation and overall climate change mitigation goals
  • Certification to this standard continues to be an approved compliance route to meeting the requirements of Energy Savings Opportunity Scheme Regulations (ESOS)

Improved reputation

  • Establishes a process for continual energy performance improvement
  • Helps you meet your environmental and carbon reduction targets

Certification

Certification
Steps

Certification of Organizations

The usual path for an organization that wishes to be certified against ISO 50001 is the following:

1. Implementation of the management system:

Before being audited, a management system must be in operation for some time. Usually, the minimum time required by the certification bodies is 3 months.

2. Internal audit and review by top management:

Before a management system can be certified, it must have had at least one internal audit report and one management review.

3. Selection of the certification body (registrar):

Each organization can select the certification body (registrar) of its choice

4. Pre-assessment audit (optional):

An organization can choose to perform a pre-audit to identify any possible gap between its current management system and the requirements of the standard

5. Stage 1 audit:

A conformity review of the design of the management system. The main objective is to verify that the management system is designed to meet the requirements of the standard(s) and the objectives of the organization. It is recommended that at least some portion of the Stage 1 audit should be performed on-site at the organization’s premises.

6. Stage 2 audit (On-site visit):

The Stage 2 audit objective is to evaluate whether the declared manage - ment system conforms to all requirements of the standard, is actually being implemented in the organi - zation and can support the organization in achieving its objectives. Stage 2 takes place at the site(s) of the organization’s sites(s) where the management system is implemented.

7. Follow-up audit (optional):

If the auditee has non-conformities that require additional audit before be - ing certified, the auditor will perform a follow-up visit to validate only the action plans linked to the non- conformities (usually one day).

8. Confirmation of registration:

If the organization is compliant with the conditions of the standard, the Registrar confirms the registration and publishes the certificate.

9. Continual improvement and surveillance audits:

Once an organization is registered, surveillance activi - ties are conducted by the Certification Body to ensure that the management system still complies with the standard. The surveillance activities must include on-site visits (at least 1 per year) that allow veri - fying the conformity of the certified client’s management system and can also include: investigations following a complaint, review of a website, a written request for follow-up, etc
