Amtico Spacia

* EPD transport and installation scenario, not this project's. THE PUBLISHED EPD DOES NOT RECONCILE IN ITS A1-3 ROW. The three split components as printed (fossil 7.46, biogenic 1.80e-1, luluc 4.94e-1) sum to 8.134 against a declared GWP-total of 8.15, a residual of 0.016 that exceeds the 0.011 available from rounding. The discrepancy is one mis-rounded cell in the fossil column: A1 5.16 + A2 0.187 + A3 2.12 = 7.467, which should print as 7.47, and BRE printed 7.46. With 7.47 the split reconciles to 8.144, within tolerance. The total column is sound (6.12 + 0.187 + 1.84 = 8.147, printed 8.15). Values are recorded exactly as published rather than silently corrected, so this record continues to agree with the document it cites. GWP-total is treated as authoritative. Worth raising with Amtico at the next data check. Module D shows potential impacts or benefits from reuse, recovery or recycling after the product's assessed life. It is reported separately and never added to A-C. Do not compare bar lengths between materials. Each chart may use a different scale and declared unit.

* A4/A5 are EPD scenarios, not project-specific results. Module D is outside the A–C system boundary and is not added to A–C. Module nomenclature follows BS EN 15978 / EN 15804. Declared values are suitable as inputs to a whole life carbon assessment under the RICS Professional Standard (2nd edition); this panel is not an assessment.

* Includes the EPD’s A4/A5 scenario assumptions, not project-specific transport or installation. This is the aggregation the proposed Part Z applies upfront limits to. The A1–A3 figure includes declared biogenic storage of 0.18 kgCO₂e; Part Z aggregates upfront carbon excluding sequestered carbon, which is the assessor's adjustment to make.

B4 (replacement) follows the building, not the product: an assessor multiplies replacement cycles by project quantities. This record supplies the service life and does not compute B4.
