SEU started on a plant floor in Dublin, with a spreadsheet, a clipboard, and the same six-week energy audit run by hand one time too many. The conviction was simple: the analytical heart of that audit should be a living model — not a PDF that’s out of date the day it’s printed.
“An auditor spends five of their six weeks rebuilding the same spreadsheet. I wanted that part to take an afternoon — so the judgement, the part only a human does well, gets the week it deserves.”
Rajendra is a chartered energy engineer who spent twelve years on pharmaceutical utilities across Ireland and the EU — WFI loops, pure-steam systems, cleanroom AHUs, chiller plant. He built SEU to put that hard-won method into every engineer’s hands, grounded in the same standards a regulator expects.
No figure ships without a named source. A chiller’s saving, for instance, is benchmarked against the best COP physically achievable at its actual refrigeration lift — never an impossible upgrade a regulator would laugh at.
Steam enthalpies come straight from the IAPWS-IF97 tables; boiler efficiency from an ASME PTC 4 heat-loss balance, not a nameplate sticker; chiller energy from the AHRI 550/590 part-load curve. The plant is modelled as it behaves.
A model is a hypothesis until it meets a meter. Upload an interval series and SEU shows the model-versus-measured variance, plainly — a small gap is confidence, a large one is a finding worth chasing.
