`_total_floor_area_from_building_parts` previously summed only `sap_floor_dimensions[*].total_floor_area`; the RR floor area lives under `sap_room_in_roof.floor_area` per RdSAP §3.9 convention and was dropped from the per-bp TFA sum. Cert 9501 (113.08 m² real TFA, of which 31.8 m² is RR) showed TFA 81.28 on the API path — the cascade then under-computed occupancy N (Appendix J), HW kWh (Appendix J), lighting kWh (Appendix L), and internal gains. Add the RR contribution to the sum. The top-level `schema.total_floor_area` scalar (integer-rounded for cert 9501: 113 vs raw 113.08) is still the fallback when no per-bp dims are lodged. Re-pinned residuals (improvements — TFA now includes the previously- dropped RR storey): - 0240: SAP -15 → -14, PE +15.69 → +12.49, CO2 +0.90 → +0.70 - 6035: PE +49.51 → +48.30, CO2 +1.14 → +1.10 Effect on cert 9501 API path: TFA 81.28 → 113.08 (= worksheet 113.08 exact). SAP delta still -9.32 vs worksheet — the remaining gap is dominated by the missing PV credit (£250 — next slice). Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com> |
