How it works
From your systems to a verified passport.
Norruva links your Declaration of Performance, EPD and CE data, validates against the CPR model, and publishes one authoritative, machine-readable record.
Connect your data
Pull the data you already hold from the systems you already run — no re-keying.
Validate against the model
The sector template checks every required field and flags gaps before anything is published.
Anchor & publish
Norruva anchors the passport and resolves it from the product’s QR or Digital Link, with a full audit trail.

Common questions
Questions construction teams ask.
How does the passport relate to the CPR?
The revised Construction Products Regulation aligns the Declaration of Performance with a digital product passport. Norruva links your DoP, EPD and CE data in one record.
Where does embodied-carbon data come from?
From your Environmental Product Declaration (EN 15804). Norruva reads the A1–A3 figures into the passport rather than re-keying them.
Does this replace the Declaration of Performance?
No — it digitises and links it. The declared characteristics stay authoritative; the passport makes them machine-readable and verifiable.
Who consumes the passport?
Specifiers, contractors, auditors and building-level material inventories — all reading one authoritative source.
