Applies to: parameters.thermal_conductivity, parameters.specific_heat, parameters.density
Where: Table 3.46, lightweight aggregate concrete block row, p. 3-49
Publishes density 600 kg m-3, thermal conductivity 0.2 W m-1 K-1 and specific heat 1000 J kg-1 K-1.
Applies to: parameters.albedo
Where: Table 3.40, concrete block row, p. 3-45
Publishes absorptivity 0.56-0.69 and emissivity 0.94. The complementary albedo interval is 0.31-0.44 and contains the stored albedo 0.375; it does not support stored emissivity 0.90.
Where: Pre-migration Spartacus Material row 36248196
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 albedo 0.375 within the concrete-block interval; stored emissivity 0.90 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 emissivity 0.90 unreferenced instead of extending CIBSE beyond what its table states. issue #888 |
| 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 albedo as assumed within 0.31-0.44 and emissivity as unreferenced and assumed. |
| Identity | supported Legacy ID 36248196 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 emissivity 0.90 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.
