Applies to: parameters.thermal_conductivity, parameters.specific_heat, parameters.density
Where: Table 3.46, dense exposed precast concrete row, p. 3-49
Publishes density 2100 kg m-3, thermal conductivity 1.56 W m-1 K-1 and specific heat 1000 J kg-1 K-1.
Applies to: parameters.emissivity
Where: Table 3.40, concrete row, p. 3-45
Publishes absorptivity 0.65-0.80 and emissivity 0.85-0.95. Stored emissivity 0.90 is within the interval; complementary albedo 0.20-0.35 does not contain stored albedo 0.375.
Where: Pre-migration Spartacus Material row 36248188
Stores the same complete tuple under MAPSECC Ref 90240069; the root spreadsheet contains the same row, excluding YAML migration as the cause of the attribution.
| Name | supported Guide A Table 3.46 contains the corresponding material row; the historical catalogue retains the current label. |
|---|---|
| Target | supported The source tables and historical catalogue describe thermophysical and radiative material properties. |
| Values | supported Table 3.46 publishes the exact thermal tuple. Table 3.40 places stored emissivity 0.90 within the concrete interval; stored albedo 0.375 is retained only as an unreferenced legacy assumption. |
| Source | supported CIBSE Guide A supports the thermal tuple and the scoped radiative field. Field-level metadata leaves albedo 0.375 unreferenced instead of extending CIBSE beyond what its table states. issue #884 |
| Place | not applicable The generic material row makes no observation-place claim. |
| Representativeness | not applicable The generic material row makes no site, city or regional evidence-reach claim. |
| Method | supported Literature is the record-level method for the CIBSE-supported values. Canonical overrides mark emissivity as assumed within 0.85-0.95 and albedo as unreferenced and assumed. |
| Identity | supported Legacy ID 36248188 identifies the retained catalogue row; correcting its record and field-level provenance does not change the stable path, values or material identity. |
This correction changes provenance metadata only. CIBSE is scoped to the values it supports, while albedo 0.375 remains an explicit unreferenced legacy assumption. The material is unlinked from any current construction record. The stable record path remains unchanged because paths are database identities, not citations.
