The recast Energy Efficiency Directive (EU 2023/1791) makes energy audits mandatory for every enterprise above 10 TJ a year — roughly 2.8 GWh, a line most GMP pharma sites clear many times over. The first are due 11 October 2026, and audit capacity has tightened into every EU deadline on record. SEU builds the analytical core of that audit in days, structured to the EN 16247-1 headings an assessor checks.
Every prior EU/UK audit cycle ended in a late pile-up and assessor scarcity. Starting in the deadline quarter means paying peak consultancy rates for the same model SEU builds now.
What EN 16247-1 and EED Annex VI ask of an audit, and where the SEU report carries it.
Bill reconciliation — modelled annual energy held against your 12-month utility bills with the residual stated plainly — plus IPMVP Option C calibration against an interval meter export.
Energy baseline (EnB), normalised EnPIs (kWh/m², kWh/unit), energy by end-use, and an 8,760-hour load profile with load-duration and pattern decomposition.
A per-equipment first-law balance across the whole utility network, and a Significant Energy User register with Pareto coverage — the 80/20 of where the energy actually goes.
Measures ranked on NPV and IRR over the analysis horizon with fuel and electricity escalation — and a marginal abatement cost curve for the carbon view.
Every measure carries capex, saving, NPV, payback and GMP change-control triage; the decarbonisation roadmap sequences them and the M&V protocol defines how savings get verified.
The entire model — equipment, topology, assumptions, anchors — saves to a file you own. Re-open it next year, re-reconcile against the new bills, and the audit regenerates.
SEU produces the analytical core; formal certification and sign-off remain with your qualified auditor or certification body. See the methodology for what each engine rests on — and its honest limits.
SEU produces the analytical core of one — an energy review structured to the EN 16247-1 headings an auditor checks: a measured-data basis (bill reconciliation plus optional meter calibration), coverage of the significant energy users, life-cycle-cost-ranked recommendations, and a storable model for follow-up. Formal certification and regulatory sign-off remain with your qualified auditor; SEU is the engine under that work, not a rubber stamp.
Under the recast Energy Efficiency Directive (EU 2023/1791), enterprises averaging above 10 TJ of annual energy use (≈2.8 GWh) must complete an energy audit every four years — the first by 11 October 2026. Above 85 TJ (≈23.6 GWh), an audit is no longer enough: a certified energy-management system such as ISO 50001 is required by 11 October 2027. Most GMP pharma sites sit well above both lines.
There is nothing to install and no integration: SEU runs in the browser, the model is stored on your device, and no plant data reaches our servers. It sits outside the BMS control loop and writes to nothing, so it is decision-support outside the GxP-validated estate — the long procurement gate never opens.
Yes — and that is often the fastest path. Your appointed auditor keeps the judgement, the site walk and the sign-off; SEU does the weeks of spreadsheet model-building that sit underneath. The audit stays their deliverable.
That the model has been held against metered reality and the variance is shown plainly, not hidden. The first anchor is your utility bills (annual electricity and fuel against the modelled totals — the site-closure check in the report); an interval meter export then sharpens that to a load profile. The report states its basis either way: bill-anchored, or benchmark estimate.
A fixed-fee pilot audit gets the analytical core done now — before the deadline quarter prices it like an emergency.
