Understanding Energy Conversion, Flows and Losses in a Factory

Understanding energy flows helps a company see where energy enters, how it is converted and where losses occur. This article introduces a reference on energy conversion, flows and losses for technical personnel and energy auditors.

How to approach the reference

• Define the survey boundary: the whole factory, a workshop or a particular equipment system.
• List incoming energy sources and the corresponding uses.
• Draw the stages of energy conversion, transmission and use.
• Mark locations with measured data, data gaps and losses requiring investigation.

Prepare data for practical application

Read the document alongside process diagrams, energy bills, operating logs and production figures for the same period. This information helps relate the model in the reference to actual factory conditions.

Use consistent units, time periods and measurement boundaries when preparing an energy balance. Clearly identify estimates so they are not confused with measurements. Evaluate proposed measures against the specific operating conditions.
