ISO 50001

There are many good reasons to focus on energy efficiency within your organization. From a global perspective, it helps achieve the urgently needed reduction in greenhouse gas emissions. However, an ISO 50001-certified Energy Management System also provides significant economic benefits.

An ISO 50001-certified Energy Management System can help your organization continuously improve its energy performance, including energy efficiency, energy use, and energy consumption. This leads to ongoing and sustainable reductions in energy costs, which in turn enhances your competitiveness. It also improves your reputation among customers and stakeholders.

Transition Timeline

The schedule foresees that all certification bodies will be converted by 30 November 2023. The exact date of our transition is not yet known, but we will inform you as soon as it is confirmed.

For new clients, the new accreditation requirements will apply from the moment our accreditation is updated.

For existing clients, the new accreditation requirements—particularly those regarding the calculation of audit time—will be applied no later than the next recertification.

Until the accreditation is transferred to ISO 50003:2022, audit time will be calculated according to the previous accreditation standard, ISO 50003:2016. Effort calculated this way applies to the entire three-year cycle. When submitting a quotation, the relevant date is the date the quotation is sent to the client.

“Plan-Do-Check-Act” as the Foundation of an Energy Management System

ISO 50001 is based on the Plan-Do-Check-Act (PDCA) model, divided into four phases, and can be understood as a continuous improvement process. This ongoing improvement process aims to prevent disruptions, ensure timely adaptation to changing conditions, and achieve new potential energy savings.

Plan: The first step is an energy review: establishing the organization’s energy baseline, defining Energy Performance Indicators (EnPIs), setting energy objectives and policy, and developing action plans.

Do: In the Do phase, the Energy Management System (EnMS) is implemented and initial steps toward deployment are taken. Along with creating the necessary structures, this may involve establishing communication and documentation processes and training employees. Employees must demonstrate both technical competence and awareness.

Check: The Check phase focuses on monitoring, measuring, and analyzing energy performance. At the end of this phase, a management review is conducted, and actions are either stopped, adjusted, or maintained.

Act: In the Act phase, new measures are taken to continuously improve energy performance and the EnMS. Adjustments may also be required, for example, to energy objectives, EnPIs, baselines, or the energy policy itself.

What Are the Changes?

Audit Time Calculation

Updated complexity values result in minor adjustments to the required audit time.
Pareto method is applied to determine energy types (≥ 80% of total consumption).
Specific rules for sampling apply to organizations with multiple sites.
Client questionnaire: Requests information on points of energy consumption and unmanned locations for calculation purposes (the certificate and, if applicable, the certificate annex remain unchanged).
