SEU

Significant energy use

Energy use accounting for substantial energy consumption and/or offering considerable potential for energy performance improvement.

Also known asÖEKsignificant energy uses

ISO 50001 requires the organization to determine significant energy uses from the energy review. SEUs drive operational control, competence, EnPIs, and action plans.

AEYS implements SEU selection as ÖEK analysis: Excel source files, TEP/TJ totals by process and sub-process, a priority matrix, and an 80% cumulative-share threshold. Each selected SEU can be linked to a unit, energy source, and trained model.
