An example
This could be your situation.
Take one company as an example: three sites, three spreadsheets, no shared answer.
Nobody can consolidate.
Nordhavn Industries, 2,400 people in Hamburg, Lyon and Porto. A client asks where the group stands. Each site answers in its own spreadsheet, with its own scales.
Three weeks, a single base.
One ISO 50006:2023 assessment launched across all three sites at once, from the managers’ interview notes. The framework was already written, its 10 themes and levels L1 to L5 too.
Two costs avoided before being committed.
A score of 53 out of 100, with the gap concentrated on three themes. The AI companion spotted that two actions duplicated those of another audit. The committee report took one sentence to request.
What it saved them
- 3sites measured on the same base, instead of three questionnaires to reconcile
- 2duplicate actions caught before the spend
- 1committee report, with no manual rework
These figures are an example. They could be yours.
The standard imposes processes. Datamensio says where you stand.
01
The framework is already written
Themes, questions and levels L1 to L5, all written. You do not start from an empty spreadsheet.
02
The score lands the same day
Online, by self-assessment link or in interview. Theme by theme, comparable over time.
03
The gap becomes a costed plan
Every step up carries its action. The AI prioritises on expected effect, not on the order of the standard.
04
Progress can be demonstrated
Campaign after campaign, against your target and against your own past. That is what your board asks for.
The maturity scale
One level, the next, and the action that links the two.
This mechanism (one level, the level above, and the action linking the two) is what turns a finding into a trajectory.
Do your energy performance indicators account for the relevant variables that influence consumption?
- N1
Consumption is tracked as a raw figure, taken from invoices or the main meter. No influencing variable is identified.
- N2
A simple ratio exists, for example kWh per tonne produced, but it is calculated without analysing other variables and discussed only when it changes.
- N3
The relevant variables for significant uses are identified and built into the EnPI calculation. Indicators are calculated at a defined frequency.
- N4
EnPIs rest on adjusted, verified models, gaps are analysed with operators and drift triggers a tracked action.
- N5
Models and variables are periodically reviewed against changes in the process and product mix, with documented tracking of revisions.
Action to move from L2 to L3
For each significant energy use, list the relevant variables with the production manager, test their correlation against twelve months of metering data, then add the recalculated EnPI to the monthly performance review dashboard.

What this framework covers
ISO 50006 is the guidance standard that supports ISO 50001 on one specific technical point: measuring energy performance. It describes how to identify significant energy uses, select the relevant variables that influence consumption, build energy performance indicators and pair them with comparable energy baselines. It also explains how to normalise data so that two periods, two lines or two sites can be compared. It cannot be certified: it makes the measurement defensible.
This is where management gets complicated. Many sites track kWh without knowing whether an observed drop comes from an efficiency measure or a fall in activity. Do your EnPIs account for the relevant variables, outdoor temperature, tonnage produced, product mix, load factor? Has your baseline been frozen for years without a documented adjustment? Does your metering data cover significant energy uses, or only the main meter supplied by the utility? Do production managers have an indicator they understand and can act on?
The 2023 version of the standard broadened the scope, with more material on data normalisation and benchmarking between entities. One confusion recurs often: comparing sites only makes sense if measurement boundaries, variables and reference periods are consistent. Without that consistency, internal ranking produces reversed conclusions. Another point of caution: an EnPI is not a target. The target is set from the indicator, once it is reliable.
The maturity assessment answers a different question from a compliance audit. An audit asks whether the requirement is met, yes or no. The assessment places each practice on a progressive scale, from no measurement at all to management reviewed periodically, and names the action that moves it up to the next level. The result is not an opinion, it is a costed trajectory: a score by theme, a target, and the gap turned into an action plan.
Within Datamensio, the framework is ready to use and editable. The AI adjusts the themes, questions and level wording to your sector, process industry, food and beverage, mechanical engineering or multi-site services, or builds a variant from your own procedures and metering plans.
Reference standard: ISO 50006:2023
The themes assessed
Scope and measurement boundaries
Defining system limits, breakdown by site, workshop or process, consistency between measurement scope and management scope.
Significant energy uses
Identifying and prioritising uses, selection criteria, coverage of utilities and processes, review as the asset base evolves.
Relevant variables and static factors
Identifying variables that influence consumption, production, product mix, climate, load factor, distinction from static factors.
Building energy performance indicators
Choice of EnPI type, absolute value, ratio, statistical model, fit with the use being tracked, clarity for operators.
Energy baselines
Choice of reference period, representativeness, conditions for adjustment, traceability of revisions and justifications.
Data collection and quality
Metering plan, instrumentation, acquisition frequency, instrument calibration, handling of missing or aberrant data.
Normalisation and benchmarking
Normalisation methods, comparability across periods and entities, internal and external benchmarking, interpretation caveats.
Targets and performance tracking
Setting targets from EnPIs, drift thresholds, review frequency, alignment with production monitoring.
Reporting and ownership by operational teams
Distribution to production teams, dashboard readability, reporting to management, decisions made on the basis of indicators.
Improving the measurement system
Lessons learnt, revision of EnPIs and models, upskilling teams, comparing performance over time.
A short version of the framework, with 35 questions, is available for the online self-assessment.
Frequently asked questions
Can ISO 50006 be certified?
No. It is guidance on measuring energy performance. Certification applies to ISO 50001, for which ISO 50006 feeds the indicators and baseline. The assessment measures the maturity of your measurement practices and prepares for the audit, it does not issue any certificate.
What is the difference between this assessment and a regulatory energy audit?
An energy audit identifies savings potential within a given scope, at a given date. The maturity assessment evaluates your ability to measure and manage performance over time: data quality, robustness of EnPIs, ownership by operational teams. The two complement each other.
How long does the assessment take?
As a self-assessment, the short version is filled in during a single working session. In collaborative mode on an industrial site, allow one to two weeks generally, most of the time spent retrieving metering plans and data from production and maintenance.
Can the framework be adapted to our sector?
Yes. Questions, levels and themes can be edited, and the AI can produce a version adapted to your process from your own documents. You remain the owner of the framework, which sets Datamensio apart from tools that impose a fixed grid.
Can several sites be compared with each other?
Yes, this is one of the main uses. The same framework is rolled out to each business unit, scores by theme can be compared between entities and against previous assessments. A cross-site roadmap then consolidates the action plans from the various sites.
Do respondents need metrology expertise?
The questions cover practices around defining, collecting and using indicators, not instrument configuration. An energy manager can answer them, and collaborative mode allows instrumentation questions to be assigned to the maintenance or metrology contact.
How is the action plan costed?
Every gap between the score achieved and the target generates an action. The service catalogue offers a response for each action, with cost, timeframe and expected impact on the score. The AI then groups these actions into a prioritised roadmap.
Where is the data hosted?
In France, with OVH, backed up with Scaleway. No transfer outside the European Union. The AI models used can be selected, including from European providers.
