SUEWS database pre-migration workbook: database.xlsxLater compilation

Where: Pre-migration Spartacus Material row 36248161

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

Medium-weight block entries use conductivities 0.31-0.83, densities 920-1940, and specific heat 840. No row states the stored 0.51/1000/1400 trio with albedo 0.37 and emissivity 0.92.

Assessment findings

Namesupported
The historical catalogue row supplies the Concrete Block (Medium) configuration label.
Targetsupported
The row stores optical and thermal material properties.
Valuessupported
The exact tuple is supported as a retained historical configuration row, not as a CIBSE medium-block condition; the checked Guide A entries have different conductivities, densities, or specific heat.
Sourcesupported
Unreferenced is correct because no CIBSE row states the complete tuple. source_legacy_ref 90240071 retains the migrated registry link without exporting it as the parameter publication.
issue #260
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 distinguishes retention of the configuration tuple from a verbatim literature material.
Identitysupported
Legacy ID 36248161 identifies the distinct retained material-registry row; no narrower physical block condition is inferred.

Scientific note

The tuple is retained exactly as a historical configuration artifact. The checked CIBSE tables contain several non-interchangeable medium-weight block conditions and do not publish the complete five-field row. Source unreferenced, method assumed, and source_legacy_ref 90240071 make the distinction explicit without choosing a replacement identity or changing any value.
