Making efficiency transparent

Energy performance indicators

How do you know if your systems are energy efficient or if measures to reduce energy demand at your company are having the desired effect? These are increasingly common questions. At the same time, companies are facing growing pressure to introduce or improve their sustainability reporting; stakeholders wish to see facts and figures that demonstrate climate action. ÖKOTEC has developed a system of energy performance indicators that allows companies to reliably monitor and assess their energy consumption, energy costs, and carbon emissions.

ISO 50001 – Energy Management Systems

Demonstrating continuous improvement with performance indicators

Companies with an ISO 5001 certified energy management system are required to demonstrate continuous improvement in energy efficiency based on reliable metrics.

  • How can I demonstrate improvements in line with ISO 50001?
  • How can I reliably monitor and evaluate energy efficiency?
  • What criteria must be fulfilled for the certified monitoring and evaluation of efficiency?
  • How can I quantify potential savings using benchmarks?
  • How can I evaluate the effectiveness of efficiency measures?

ÖKOTEC has answers to these and many other questions. Make the most out of your energy management system by working with us.

An energy management system without performance indicators is like the Olympics without a stopwatch or measuring tape.

Methodological guide for energy managers

Optimizing your efficiency, step-by-step

The German Environmental Ministry publishes a practical guide on how to use energy performance indicators. Developed in cooperation with ÖKOTEC, DENEFF, and Fraunhofer ISI, the guide is geared towards companies with an ISO 50001 energy management system who wish to refine their monitoring system and boost the efficiency of their business activities. The guide places a central focus on the adoption of the energy performance indicators (EnPIs) developed by ÖKOTEC and DENEFF on behalf of the German Environmental Ministry. It also discusses ISO 5006, which provides practical assistance with establishing, using, and maintaining EnPIs as part of an ISO 50001 energy management system. We show you how to achieve continuous optimization with a step-by-step process, including:

  • Determination of efficiency targets and system boundaries
  • Data acquisition (input measurement/baselines)
  • Implementation of energy efficiency measures
  • Analysis for confirming measure effectiveness
  • Reporting

Best-Practice Case Studies

Funded by the German Environmental Ministry, the EnPI-Connect project was dedicated to the further development of ÖKOTEC’s indicator methodology. The EnPI methodology was tested in combination with the energy management software EnEffCo® at three different companies: Mercedes-Benz Berlin; the food manufacturer Stockmeyer; and the laundry services provider City Clean. The project partners realized considerable energy savings thanks to the optimization of their various energy, production, and utility systems.

Energy performance indicators in practice

Benefits and use cases for energy performance indicators

Monitoring

Energy performance indicators can be used to filter out the effects of outside factors on your energy demand. Thanks to reliable measurement data, you can verify the performance of your systems as well as permanently monitor their efficiency. You also receive early notification of performance issues.

Benchmarking

Energy performance indicators allow you to compare the performance of multiple significant energy consumers (SEUs). Benchmarking allows you to quickly identify incorrect control settings or inefficient technology.

Integration and CO2-Footprint

Energy performance indicators allow your energy systems to be intelligently connectable. You receive transparency concerning the energy footprint associated with materials and products as they make their way through production and supply chains, all the way up to the calculation of specific Product Carbon Footprints (PCFs).

Reporting

ISO 50001:2018 Energiemanagement-System
Energy performance indicators allow you to compare the cost and benefits of a given production and energy system, thus enabling the calculation of overall efficiency. Expenditures can be assessed in the following units: energy, price, or the CO2 factor. Corporate energy managers thus have access to meaningful information that can be used in a variety of ways.
