What SEU is, how the numbers hold up, where your data lives, and what it does and doesn’t replace — in plain terms, with nothing dressed up.
SEU is a pharmaceutical-facility energy twin. You describe your plant — boilers, WFI and pure steam, chillers, cleanroom AHUs, lyophilisers — and it builds a physics-grounded model of the utilities, runs 8,760-hour analytics, finds the Significant Energy Users and the ranked savings, and assembles the analytical core of an ISO 50001 / TCFD audit you can regenerate any day the plant changes.
Energy and utilities engineers at GMP pharmaceutical sites, and the sustainability leads and auditors who work with them. It speaks the language of classified cleanrooms, steam systems and chiller plant rather than generic commercial HVAC.
The model is built and computed in your browser and persists in your device’s local storage — SEU does not run a server that holds your facility data. Anything leaves your machine only if you choose to: uploading a meter file (processed locally) or sending a single request to the opt-in AI assistant. For a deployment it runs single-tenant inside your own environment.
Every figure comes from first-principles engines — IAPWS-IF97 steam properties, ASME PTC 4 boiler efficiency, AHRI 550/590 chiller part-load, ASHRAE psychrometrics — not placeholder curves. The engine is deterministic, so the same plant always yields the same result, and you can calibrate it against your own meter data (IPMVP Option C) to see model-versus-measured variance.
A consultant’s audit is a one-off PDF that is stale the moment a chiller is swapped. SEU is a living model: it is built once, defended line by line, and re-run on demand. The deliverable is the same analytical backbone a six-week consultancy produces — M&E balance, SEU register, pinch, cashflow, TCFD — but it stays current with the plant.
A first model is generated from a pharma-segment template in an afternoon: pick your segment, country and climate, and refine the pre-built schematic to match your site. You get a full analysis and a board-ready report from there, then sharpen the inputs over time.
No. The sample gallery holds deeply-researched reference plants for each pharma segment — sterile fill-finish, OSD, API, biologics, lyophilisation, QC lab — so you can explore a full simulation, the opportunities and the audit for a plant like yours before entering a single number of your own.
The energy review is structured on ISO 50001; the physics rests on IAPWS-IF97, ASME PTC 4, AHRI 550/590 and ASHRAE; the context is EU GMP Annex 1, ISO 14644 and 21 CFR Part 11; and the disclosures map to the GHG Protocol, IPMVP, TCFD and CSRD ESRS E1.
Yes. The report assembles a cover, executive brief, mass-and-energy balance, ISO 50001 energy review with the SEU register and Pareto, pinch analysis, NPV cashflow, TCFD section and a decarbonisation pathway with a MACC and M&V plan — rendered for the browser’s native Save-as-PDF, so it works offline with perfect fidelity.
It does the analytical core — the modelling, the calculations, the ranked measures and the documentation — that an auditor would otherwise rebuild by hand. Certification, formal sign-off and on-site verification stay with your qualified auditor; SEU gives them a defensible, regenerable starting point instead of a blank spreadsheet.
Yes. Upload an interval meter series and SEU reconciles the model against measured reality — an IPMVP-style baseline and variance — so the audit is grounded in your site’s real consumption, not just nameplate assumptions.
Two ways in. The pilot audit is a fixed fee, agreed before we start — one site, the full audit deliverable, two-week turnaround (see the pilot page). A continuing deployment — the maintained model, M&V loop and annual compliance cadence — is scoped as a single-tenant engagement with your IT and quality teams. The sample plants and a live demo are open to explore first, free.
It produces the analytical core of one, structured to the EN 16247-1 headings an assessor checks: a measured-data basis (bill reconciliation, optional meter calibration), coverage of the significant energy users, life-cycle-cost-ranked recommendations and a storable model for follow-up. Certification and sign-off stay with your qualified auditor — see the compliance page for the requirement-by-requirement mapping.
Under EU 2023/1791, enterprises above 10 TJ of annual energy use (≈2.8 GWh) owe an energy audit every four years — the first by 11 October 2026. Above 85 TJ (≈23.6 GWh) a certified energy-management system such as ISO 50001 is required by 11 October 2027. Most GMP pharma sites are above both.
No install, no integration, no plant data leaving your device — SEU runs in the browser and writes to nothing. It sits outside the BMS control loop, so it is decision-support outside the GxP-validated estate rather than a system your IT or CSV programme has to qualify.
Yes — your appointed auditor keeps the site walk, the judgement and the sign-off, and uses SEU for the weeks of model-building underneath. The audit remains their deliverable; the model remains yours.
Held against metered reality, with the variance shown rather than hidden. The first anchor is your utility bills — the modelled annual electricity and fuel against the declared 12-month totals, reported as a site-closure percentage. An interval meter CSV sharpens that into a load-profile comparison (IPMVP Option C). The report always states which basis it stands on.
