TS EN 16231

TS EN 16231 is a standard devoted to the methodology of energy efficiency benchmarking. It focuses on how energy-consumption data and indicators should be defined and organised so that performance can be compared within an organisation or between different organisations.

Defining what is being benchmarked

A central idea in energy benchmarking is to set clear boundaries around the subject of comparison. The standard recognises that benchmarking may be applied to facilities, activities, processes, products, services, or entire organisations. That distinction matters because energy use can vary significantly with operating conditions, technology choices, scale, and behavioural factors, even when the output appears similar.

The standard also provides guidance on choosing the appropriate level of detail for data collection, processing, and review, based on the objective of the benchmarking exercise. In practical terms, benchmarking may rely on technical indicators, but it may also include qualitative and behavioural information when that helps explain differences in performance. TS EN 16231 does not set specific energy-performance requirements or numerical thresholds.

In general technical practice, benchmarking is a familiar tool in energy management and continual improvement. It helps organisations compare like with like, identify where performance gaps exist, and track progress over time. For broader improvement cycles such as PDCA, the detailed management approach belongs to the organisation’s own management systems.
