Carbon and evidence
Product Evidence
Evidence currently held for the NBK Terracotta product record.
Recorded Carbon Result
A1–A3 GWP-total per m² of façade panel (ref 41.4 kg/m²), per EPD
A1–A3 covers raw-material supply, transport to manufacture and manufacturing. It is product-stage information, not a whole-life result.

Externally (third-party) verified IBU EPD for TERRART-Light 28. Impact scales with panel mass (39–47 kg/m², reference 41.4 kg/m²). A1–A3 is relatively high because fired ceramic is energy-intensive; the trade-off is very long service life. A4/B modules not declared.

Service Life — the B4 Replacement Input
50 years · EPD reference service life
The declaration gives at least 50 years, taken from the BBSR table of the BNB rather than from testing of the panel, and states that the panels last as long as the building.
≈2 installations over a 60-year building study period.
2 claims and 1 certification are held in the staging record but not presented as product evidence because an exact public source has not yet been mapped.
