Provenance evidence

Awaiting sign-off

Published value · assessed by provenance-audit · 2026-08-26. Agent assessment is evidence preparation, not human verification.

Apache-Tables User Guide: IES Virtual Environment 6.4Parameter source

Applies to: parameters.thermal_conductivity, parameters.specific_heat, parameters.density

Where: Table 6, Roofing Felt row, p. 11

Publishes 0.190 W m-1 K-1, 837 J kg-1 K-1 and 960 kg m-3; no optical values.

SUEWS database pre-migration workbook: database.xlsxLater compilation

Where: Pre-migration Spartacus Material row 36248156

Stores the complete tuple under placeholder Ref 99240099; migration lineage only.

Assessment findings

Namesupported
Both rows identify Roofing Felt.
Targetsupported
Both describe building material properties.
Valuessupported
IES publishes the exact 0.19/837/960 thermal tuple; 0.18/0.92 remain migrated assumptions.
Sourcesupported
IES is scoped to the thermal leaves; field overrides keep both optical leaves unreferenced.
issue #279
Placenot applicable
This is a generic material.
Representativenessnot applicable
This material makes no geographic evidence-reach claim.
Methodsupported
Literature applies to thermal leaves; optical leaves are assumed.
Identitysupported
Legacy ID 36248156, stable path and all values are preserved.

Scientific note

Field-level provenance preserves the supported thermal tuple without inferring optics from generic asphalt, bitumen or paper. The optical values remain explicit assumptions; no values or identity change.
