Clients stopped asking whether it's compliant. Now they ask how much the fix costs.
97%
of EU buildings need upgrading to hit 2050 targets. Compliance is settled; the cost of the fix is not.
~1%
the renovation rate happening today, far below what those targets demand.

the EU's own target for accelerating renovation this decade. The question your clients ask now is what the work costs, and whether your number holds.

Built for consultants

Blue Auditor standardizes asset and meter data, automates calculations, and keeps a full audit trail so you can scale delivery and safeguard your reputation.

Taxonomy 2

One method, every project

Standardized digitization and CRREM-based decarbonization analytics. The same logic whoever runs it, whichever asset, whichever client, so quality assurance stops being a manual re-check.

Real cost behind every figure

A renovation cost base built from roughly 1,500 completed European projects. When you put a CapEx number in front of a client, you defend it with comparables, not estimates.

Carbon Alignment and Retrofit Intelligence 2
EPC-2-ESG

A number that holds up

Every figure carries a documented method and a full trail. When the certifier, valuer, or bank pushes back, you point to the standard, not to the spreadsheet you built at midnight.

“We had data everywhere and no way to underwrite decarbonization. Blue Auditor’s data-led OS gave us meter-level QA, taxonomy alignment, and asset-level pathways. Now our board sees clear trade-offs and approves investments with confidence.”
