Energy Performance Indicators and Energy Baselines
How do I establish Energy Performance Indicators and Energy Baselines?
Energy performance indicators or EnPIs are defined as a measure or unit of energy performance as defined by the organisation. This can be expressed by using a simple metric, ratio, or a model, depending on the nature of the activities being measured.
Examples of Energy Performance Indicators
Examples of EnPI’s can include:
- kWh consumed per site
- kWh per linear metre of product produced
- kWh per number of staff
- kWh per square meter of occupied office space
It is critically important to determine a suitable range of relevant EnPI’s based on the results of the energy review. EnPI’s should help to demonstrate continual improvement in either efficiency, use and/or consumption.
Energy Baselines
An energy baseline (EnB) is defined as a quantitative reference(s) providing a basis for comparison of energy performance.
An energy baseline is based on data from a specified period of time and/or conditions, as defined by the organisation.
An example of an EnB:
kWh consumed in the 2015 period. Thus, energy efficiency, use and consumption can be compared against this baseline data to determine if an improvement has been achieved.
Energy baseline(s) are used for determination of energy performance improvement, as a reference before and after, or with and without implementation of energy performance improvement actions.
It is a requirement of the standard that monitoring and measurement activities should include comparison of data against the stated baseline(s)
ISO 50015 provides additional information on measurement and verification of energy performance.
ISO 50006 provides additional information on EnPI(s) and EnBs.
