Walked the worksheet section-by-section (dimensions, ventilation, fabric, internal/solar gains, MIT, space-heating requirement, fuel cost) against the calculator's matching intermediates. Internal gains and heat loss matched closely, but solar gains (worksheet line 83) was 2.2x off in January (56.9 W vs our 123.4 W) — traced to the Elmhurst BUILD entering all 12 real windows (3 orientations: NW 7.05 m2, NE 1.21 m2, SE 7.06 m2) as a single synthetic 15.32 m2 "North" group, understating solar gain. Verified by reproducing both build artifacts in the calculator: real windows + real Table-11 gating = 76.33 (our answer, matches lodged 76 exactly); collapsing to a synthetic single-North window + forcing Table 11 on = 72.62, reproducing Elmhurst's 72 almost exactly. Confirms neither residual is a mapping or calculator bug — one is a deliberate, regression-tested spec choice (Table 11) and the other is an artifact of how this specific Elmhurst reconciliation build was entered.
