TS EN 16231

TS EN 16231 is the standard for energy efficiency benchmarking methodology. It provides requirements and recommendations for defining, collecting, and comparing energy-consumption data and indicators. In practice, benchmarking differs from simply tracking a single facility’s energy use: it is intended to compare performance between entities or within one entity over time, using a structured and comparable basis.

What benchmarking is meant to do

Energy efficiency benchmarking focuses on more than total consumption alone. It uses indicators that help interpret performance in context, such as production level, service intensity, operating conditions, or behavioural influences. In general technical terms, this makes benchmarking a decision-support tool: it helps identify where performance differs, why it differs, and where improvement opportunities may exist.

How data and indicators fit together

The standard’s core subject is the identification of relevant data and indicators for energy use. In broader technical practice, a benchmarking methodology may combine quantitative measures with qualitative information, so that measured consumption can be interpreted alongside operational context. That distinction matters because two entities with similar total energy use may still have very different efficiency profiles once their activities and conditions are taken into account.

• Provides a methodological framework for comparing entities or comparing performance within one entity.
• Recognises both technical and behavioural factors related to energy consumption.
• Supports the use of quantitative and qualitative indicators together.
• Aims to improve understanding of energy performance and highlight opportunities for better efficiency.
