"Insulation At: None" is the assessor recording zero loft insulation, not an unknown — with thickness left None, u_roof fell through to the age-band "assumed insulated" default (0.16 W/m²K at band J/K) instead of the Table 16 uninsulated row (2.30), understating roof loss ~14x (issue #1590 bug 2). Harness MAE 2.701 -> 2.632 (the two ~7-SAP roof over-raters correct exactly); ceiling ratcheted to 2.64. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> |
