SUEWS database pre-migration workbook: database.xlsxLater compilation

Where: Pre-migration Spartacus Material row 36248181

Stores the exact tuple, name and MAPSECC Ref 90240069; this proves release and migration lineage only.

Guide A: Environmental designValidation

Where: Table 3.38, plywood rows, p. 3-43

Publishes plywood tuples 0.12 W m-1 K-1, 1210 J kg-1 K-1, 540 kg m-3 and 0.15 W m-1 K-1, 1420 J kg-1 K-1, 700 kg m-3; neither is the stored 0.15/2500/560 tuple.

Assessment findings

Namesupported
The historical catalogue supplies the Plywood (Lightweight) label; Guide A has plywood rows but no matching tuple.
Targetsupported
The historical row and Guide A table describe thermophysical material properties.
Valuessupported
The exact 0.15/2500/560 tuple is supported only as a retained historical configuration row. Guide A publishes two plywood tuples, neither of which matches all three stored values.
Sourcesupported
Unreferenced is correct because no located source states the complete tuple. source_legacy_ref 90240069 retains the migrated MAPSECC link without exporting it as the parameter publication.
issue #890
Placenot applicable
The generic material row makes no observation-place claim.
Representativenessnot applicable
The record makes no site, city or regional evidence-reach claim.
Methodsupported
Assumed retains the historical tuple without claiming a recovered per-field assembly method.
Identitysupported
Legacy ID 36248181 identifies the retained catalogue row. Similarity to one CIBSE conductivity value does not establish either published plywood row as the source of this complete tuple.

Scientific note

The exact row is retained as a historical configuration artifact. CIBSE does not publish its complete thermal tuple, so source unreferenced, method assumed and source_legacy_ref 90240069 expose the unresolved lineage without changing values or inventing a source. The material is unlinked from current constructions.
