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 50001:2018 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 (a level, the level above, and the action linking the two) is what turns an observation into a trajectory.
Are energy performance indicators normalised against the relevant variables and compared against an established baseline?
- N1
Tracking is limited to raw consumption taken from invoices. No baseline is established.
- N2
Indicators exist for a few uses, but they are not normalised against production or climate variables, and the baseline is not formalised.
- N3
Indicators cover the significant energy uses, are normalised against the relevant variables and compared against a documented baseline.
- N4
Deviations from the baseline are analysed at a set frequency, explained and linked to actions. Baseline adjustments are logged and justified.
- N5
Indicators are revised as processes and product mix evolve, compared across sites and used in investment decisions, with a full revision history.
Action to move from level 2 to level 3
Identify the relevant variable for each significant energy use (tonnage produced, running hours, degree days), recalculate normalised indicators over the last twelve months to set the baseline, and have this baseline validated at the energy management review.
« With Datamensio, we meet our objectives far more efficiently. The ERDF inspection services and our supervising ministry particularly appreciated an approach that gives them reliable data. »

What this framework covers
ISO 50001, in its 2018 version, sets out the requirements for an energy management system applicable to any organisation, regardless of size or sector. It calls for an energy policy driven by top management, an energy review that identifies significant energy uses, energy performance indicators linked to energy baselines, documented objectives and targets, an action plan, and evidence of continual improvement in performance, not just in the system. The standard can be certified by an accredited body.
In practice, the difficulty is not writing the energy policy, it is keeping it alive between two reviews. Are significant energy uses genuinely revised when the production mix changes, or simply carried over year after year? Are energy performance indicators normalised against the relevant variables (output, degree days, load factor) or compared against raw data that says nothing? Do workshop supervisors know their contribution, or does energy remain a single person’s file in the technical department?
One point of context comes up in almost every industrial group: how ISO 50001 fits with energy audit obligations and sustainability reporting. In several member states, ISO 50001 certification exempts organisations from the periodic regulatory energy audit, and consumption data now feeds into non-financial reporting. The energy management system becomes a data source audited by people other than the energy manager. That raises the bar on metering reliability and traceability of calculations.
The maturity assessment answers a different question from the certification audit. The audit concludes with conformity or a nonconformity against a requirement. The assessment places each practice on a progressive scale and points to the precise action that moves it up a level. It is run before an audit to prepare, between audits to steer, and across sites to compare entities whose certificates are identical but whose practices are not.
Within Datamensio, the ISO 50001 framework is ready to use and adaptable. The AI adjusts the themes, questions and levels to your industrial scope, or builds a variant from your existing energy reviews, metering plans and procedures.
Reference standard: ISO 50001:2018

A short version of the framework, with 32 questions, is available for the online self-assessment. The full version covers 10 themes and 72 questions.
Frequently asked questions
Does the assessment replace the ISO 50001 certification audit?
No. Certification is granted by an accredited body, following an audit. The assessment measures the maturity of your practices, identifies gaps and prepares you for that audit. Datamensio does not certify.
What is the difference between a compliance audit and a maturity assessment?
The audit concludes with conformity or a nonconformity against each requirement. The assessment places the practice on a five-level scale and points to the action that moves it up a level. A site can be compliant and still sit at a low maturity level on operational control.
How long does the assessment take?
The short version can be completed in one session by the energy manager. The full version, run collaboratively with maintenance, utilities and QHSE, generally takes one to two weeks, with most of the time spent gathering metering data and current action plans.
Can the framework be adapted to our processes?
Yes. Themes, questions and level wording can all be modified. The AI generates a variant tailored to your sector or built from your own energy reviews and procedures. You retain ownership of the resulting framework.
How can several plants be compared with each other?
Each site completes the same framework and gets a score per theme. The benchmark compares business units against each other and each site against its own previous assessments. A cross-site roadmap consolidates action plans shared across several plants.
How does this assessment connect with decarbonisation and sustainability reporting?
Energy performance feeds directly into scope 1 and 2 emissions and published consumption data. A mature energy management system provides traceable data. Cross-site roadmaps allow energy and carbon to be cross-referenced without duplicating actions.
Is technical expertise needed to answer?
The questions cover management practices, not equipment sizing. An energy or QHSE manager can answer them. Questions on metering or utilities operation can be assigned to a technical contact in collaborative mode.
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.
