SUEWS database pre-migration workbook: database.xlsxLater compilation

Where: Pre-migration Spartacus Material row 36248153

Stores the exact tuple, name, and Ref 90240071; this proves release and migration lineage only.

Guide A: Environmental designValidation

Where: Tables 3.37 and 3.40, p. 3-38, 3-45

Limestone rows include 1.5/720/2180, 2.9/840/2750 and 1.8/840/2420; none states the stored conductivity 0.93, specific heat 909 and density 2711.

Derivation of an urban materials spectral library through emittance and reflectance spectroscopyValidation

Applies to: parameters.albedo, parameters.emissivity

Where: Table C.1, sample S004

Publishes albedo 0.68 and emissivity 0.93 for a beige limestone specimen, but does not publish the thermal trio or prove that the historical generic row represents that specimen.

Assessment findings

Namesupported
The historical catalogue supplies the Limestone Bright configuration label; Kotthaus sample S004 is relevant to its radiative pair but does not establish that the row is that specimen.
Targetsupported
The row stores optical and thermal material properties.
Valuessupported
The exact tuple is supported as a retained historical configuration row. CIBSE does not publish its thermal trio; Kotthaus independently publishes only the 0.68/0.93 radiative pair for sample S004.
Sourcesupported
Unreferenced is correct because no located source states the complete tuple. source_legacy_ref 90240071 retains the migrated CIBSE link without exporting it as the parameter publication.
issue #262
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 compilation without claiming a recovered per-field assembly method.
Identitysupported
Legacy ID 36248153 identifies the retained catalogue row. Numeric agreement alone does not authorize identifying it with Kotthaus sample S004 or another narrower limestone specimen.

Scientific note

The exact row is retained as a historical configuration artifact. CIBSE does not publish its thermal trio, while Kotthaus sample S004 explains only the radiative pair and cannot establish specimen identity from numeric agreement alone. Source unreferenced, method assumed, and source_legacy_ref 90240071 make the mixed lineage explicit without changing values or inventing the missing thermal source.
