ISO 50001 Certification: A Practical Guide to Managing Energy More Effectively

Energy Review

An energy review is one of the most important practical activities within ISO 50001.

The organization analyzes energy use and consumption to understand its current energy performance. This review can include historical energy data, energy sources, operational conditions, equipment performance, and factors that significantly influence energy consumption.

The goal is to identify significant energy uses (SEUs) and opportunities for improvement.

Energy Performance Indicators

Energy Performance Indicators, or EnPIs, are used to measure energy performance.

An EnPI could relate energy consumption to production output, operating hours, floor area, occupancy, or another relevant variable.

For example, a factory might track energy consumption per unit of production rather than simply monitoring total electricity consumption. This can provide a more meaningful picture of whether energy efficiency is actually improving.

Energy Baseline

An energy baseline provides a reference point against which changes in energy performance can be evaluated.

A baseline may be developed using historical energy data and relevant variables. Comparing current performance with the baseline allows an organization to determine whether implemented measures are producing measurable improvements.
