ISO 50001,
automated end to end.
Ento generates the energy review, builds the performance indicators and baselines, and verifies your savings, all from your meter data and without new hardware.
Build the foundation from data you already have
With Ento, all three come out of your existing utility data. We connect to electricity, district heating, water, solar, and heat pump meters via standard utility protocols, normalize the data for weather and calendar, and automatically generate per-site indicators. No new hardware required. The energy review that traditionally takes weeks of consultancy work is in place from day one and updates continuously.
Run the standard's operations, automatically
Ento's models learn each building's normal pattern, then flag deviations the moment they happen. Alerts route to the right person by email, with the estimated cost of the deviation attached and a preliminary root-cause analysis. Every registered action is logged with its measured impact on consumption, cost, and CO2, building the documentation trail auditors ask for. The standard's operational requirements run themselves.
Prove your savings with audit-ready evidence
Ento's Measurement & Verification engine compares post-implementation consumption against a counterfactual that adjusts for weather, calendar, and operating regime. Every verified saving shows kWh, cost, and CO2 impact with the uncertainty bands an auditor can trust. The same evidence drives your management review and your continual improvement narrative, to ensure there’s no additional work to keep your certification.
How Ento meets each ISO 50001 requirement
Buildings change constantly. Ento's models are designed
to handle real-world operations automatically.

Landbrug & Fødevarer and 4BC used Ento to get certified.
Danish Agriculture & Food Council manages 110,000 m² of commercial properties across Aarhus and Copenhagen. Together with 4BC, they used Ento to build the energy review, performance indicators and baselines required for ISO 50001 — all from existing meter data, without installing any new hardware.
"Everything is in one place and we don't need to bother with manually analysing Excel sheets anymore. The Ento platform became the foundation for taking strategic decisions about our investments."
"AI alone can't get you ISO certified, but it makes the process a lot easier. It plays a pivotal role in performance evaluation, audits, and defining empirical indicators and baselines."

About ISO 50001
Under the EU Energy Efficiency Directive, companies with average annual energy consumption above approximately 24 GWh (85 TJ) over three years must implement a certified energy management system. ISO 50001 is the most widely recognized certification meeting this requirement. ISO 14001 / EMAS combined with periodic energy audits is an accepted alternative.
Certification is awarded for three years following an independent audit, with surveillance audits in between.
Still got questions?
What does Ento handle, and what's still my responsibility?
Ento automates the data-driven parts of the standard: the energy review, performance indicators, baselines, deviation monitoring, and savings verification. The parts that stay yours are the ones the standard puts in human hands by design: defining your energy policy, securing management commitment, training your team, and running internal audits and management reviews. Ento gives those activities a continuously updated evidence base, so the human work is faster and better grounded.
Do we still need an energy consultant?
It depends on how familiar your team is with the standard. Most of our customers work with a consultant for the certification phase itself, while Ento handles the underlying data infrastructure. Once certified, most teams maintain the system in-house with the consultant returning periodically. Ento reduces the hours a consultant needs to bill, regardless of how you split the work.
Will Ento's data and documentation hold up in an audit?
Yes. Every EnPI, baseline, alert, registered action, and verified saving is timestamped and traceable back to the underlying meter data. Auditors can inspect the methodology behind any number on the platform: which variables were selected, which model was used, what the confidence intervals are. The same evidence trail that proves savings internally is what you present at audit, with no parallel reporting work to maintain.
We manage hundreds of sites across multiple countries. Can we certify them all together?
Yes. Ento is designed for multi-site portfolios and supports both regional groupings and corporate-wide certifications. Each site connects once, the energy review and indicators populate automatically, and you decide how the scope of your energy management system is drawn. Customers managing 500+ buildings use Ento for exactly this purpose.
How does Ento support us between audits and at recertification?
The standard requires continual improvement, which is where most programs lose momentum. Ento keeps EnPIs, baselines, and verified savings updating live, so management reviews always have current data and your improvement trajectory is visible at any moment. When recertification comes around, three years of documentation is already in place and there's no scramble to reassemble it.
Does Ento's measurement and verification satisfy the standard's requirements?
Yes. Ento's M&V follows IPMVP with ASHRAE Guideline 14 aligned uncertainty quantification, which is the methodology ISO 50001 references for verifying energy performance improvement. Each verified saving includes the model, the variables, the confidence intervals, and the non-routine event log, which is more rigorous than most auditors expect to see.
What if we go with ISO 14001 plus energy audits instead?
The EU directive accepts that path as an alternative. Ento supports it equally well: the same energy review, monitoring, and verification feeds an ISO 14001 environmental management system, and the M&V module covers the verification part of the audit cycle. Some customers start with ISO 14001 + audits and migrate to ISO 50001 once they see how much of the work is already in place.
