Energy management is the systematic, continuous control of energy consumption in an organisation: consumption is measured, targets are set, measures are implemented and results are reviewed regularly. The framework most often used is the ISO 50001 standard.
How it works
It is based on the plan-do-check-act (PDCA) cycle. The organisation identifies where and for what it uses energy (significant energy uses), sets indicators (EnPI) and targets, implements measures, measures the outcome and adjusts the targets accordingly. Responsibility lies with management, while the day-to-day work is done by the energy manager together with maintenance and production.
Difference from an audit
An energy audit is a snapshot in time. Energy management is daily work with data: metering, evaluation, alarms when anomalies occur, and checks that the measures are holding. The two complement each other: the audit finds opportunities, and management ensures they are exploited and that the savings last.
Example from manufacturing
A plant installs sub-meters on the compressor room, paint shop and welding shop. The monthly evaluation reveals consumption outside shifts and the operating pattern. A measure (switching equipment off at weekends, repairing leaks) is recorded, and after three months its effect is verified against the data.
Frequently asked questions
Does every company have to have energy management?
No. Czech Act No. 406/2000 Coll. on Energy Management requires an audit or certified ISO 50001 depending on energy consumption (an audit above 10 TJ, ISO 50001 above 85 TJ). It also pays off voluntarily for smaller sites.
What is needed for energy management?
As required: meters, a system for collecting and evaluating data, designated responsible persons and management support. The Energy Infra Scan platform handles metering and evaluation.
