In every mandatory audit cycle to date, the work went to external assessors — and the assessors did it in Excel. With the EED’s first deadline in October 2026 and audit capacity already the binding constraint, the firm whose model-building takes an afternoon instead of five weeks takes the deadline work. The audit stays your branded deliverable, the client stays yours; SEU is the engine underneath.
The weeks an audit spends rebuilding the M&E balance in a spreadsheet collapse to hours: segment templates, a living P&ID, IAPWS-IF97 steam, ASME PTC 4 boilers, AHRI 550/590 chillers, ASHRAE psychrometrics — already wired together.
Each number carries its source and sensitivity into an assumption register, and the model reconciles against the client’s bills and meter exports with the variance stated. Your review stands on something a regulator can interrogate.
Each client plant saves to a portable model file. The next site starts from a researched segment twin; next year’s surveillance audit starts from this year’s model and the new bills — not from a blank workbook.
Everything on this site, on your clients’ plants.
One .seu.json per client site; open, re-run, hand over.
Scoped with the first partner cohort — talk to us.
On the roadmap — the audit ships today as a print-perfect PDF under your judgement.
Planned once the first cohort is live.
A deliberate line between what is live today and what is planned — partners get the same honesty the audit gives their clients.
We’re scoping per-auditor licensing and terms with a small first group of consultancies ahead of the EED deadline window. Tell us about your practice — or pressure-test the engine on a sample plant first.
