weberpral E

* EPD transport and installation scenario, not this project's. The declared total is 0.158 while fossil + biogenic + land-use-change sums to 0.15658 — a residual of 0.00142, slightly beyond the accumulated half-ulp of three-significant-figure values. This is NOT a transcription error: the declaration prints the explicit warning "Please note Climate Change Total may not be the sum of Climate Change (fossil), Climate Change (biogenic) and Climate Change (land use change)." The manufacturer is stating up front that the split will not reconcile. The declared Climate Change (total) row is treated as authoritative, per EN 15804 convention. The sibling weberpral M declaration reconciles exactly. 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 -0.0126 kgCO₂e; Part Z aggregates upfront carbon excluding sequestered carbon, which is the assessor's adjustment to make.
