How do energy management consultancies work

Energy management: ISO 50000 is supplemented by new rules

The new guidelines for energy management systems (EnMS) of the DIN EN ISO 50000 series will apply from October 2017. Up until now the focus was “only” on introducing a functional EnMS, the focus now is on demonstrating improved energy efficiency: companies must also demonstrate energy improvements and the increase in energy efficiency in the future.

In the future, proof of the continuous optimization of the energy-related performance compared to the energetic starting point (EnB) through measurable results must be demonstrated. The corresponding energy performance indicators (EnPIs) must be prepared in a comprehensible, meaningful and meaningful way - because ultimately a (verifiable) positive change compared to the starting point must be achieved, otherwise an auditor can refuse the certificate or withdraw an existing one. However, since the standards do not state any explicit methodology, many internal and external energy officers are confronted with a new and very complex task.

External advice can help

Consulting companies or broad-based electrical engineering manufacturers such as Detmold Weidmüller GmbH can provide valuable help in implementing energy management systems in accordance with ISO 50001 - because the task is anything but trivial. A particular focus should be ISO 50003 ("Requirements for bodies that audit and certify energy management systems"), ISO 50006 ("Measurement of energy-related performance using energetic output bases [EnB] and energy performance indicators [EnPI]") and ISO 50015 ("Measurement and verification the energy-related performance of organizations ”).

The aim is to coordinate processes, machines, systems and production areas with a view to the best possible use of energy and system availability.

Important aspects in the implementation

Using the example of the services offered by Weidmüller GmbH, it can be shown how the development of a concept for the EnMS introduction in accordance with ISO specifications can look like:

  • Collecting information about the energy-related performance: The consumers in the company are analyzed and suitable measuring points are selected.
  • Definition of the energy performance indicators (EnPIs): For the selected consumers, influencing variables are determined and dependencies are assessed.
  • Determination of the energetic starting basis (EnB): The status quo of the company's energy efficiency is determined and recorded.
  • Use of EnPIs and energetic starting points: Based on this developed basis, suitable efficiency measures are now proposed.
  • Adaptation or maintenance of EnPIs and energetic starting points: In the further process, the suggestions for improvement are implemented and the energy efficiency gains achieved are documented.

All from a single source

Holistic offers are ideal in view of such a complex subject, which is composed of many (equally important) individual aspects. Holistically oriented consultants are not only able to design individually tailored energy management systems together with companies, but can also help with implementation. Consulting and conception, software and controlling, hardware components for measurement and control, and finally the (regularly recurring) certification process: cross-departmental and long-term partnerships make perfect sense in the field of energy management.
