The §5 test EPC builder threaded sap_windows from the fixture but discarded `sap_roof_windows` — passing them through `make_minimal_sap10 _epc(...)`. Pre-S0380.110 the `_daylight_factor_from_cert` cascade read a single aggregate `rooflight_total_area_m2` kwarg + bulk g_L, so the test EPC builder's omission was masked. Post-S0380.110 the cascade reads per-rooflight glazing via `epc.sap_roof_windows` (Appendix L §L2a per-window g_L sum) — Triple / Double / Single distinctions matter. For cohort 000516 (the only cohort fixture with a lodged rooflight, a Double-glazed 1.18 m² × g_L=0.80 × FF=0.70 × Z_L=1.0), the empty sap_roof_windows on the test EPC undercut the daylight factor → cascade lighting (67) Jan 33.78 W vs ws 32.68 W (+1.1 W/month) → lighting_kwh_per_yr 238.65 vs ws 230.88 (+7.77 kWh/yr). Fix: thread `fixture.build_epc().sap_roof_windows` through the minimal EPC. Cohorts 000474/477/480/487/490 have no rooflights → list is None → cascade unchanged for those certs. Test movement: 000516 (67) Jan 33.78 → 32.68 ✓ EXACT. 000516 lighting_kwh_per_yr 238.65 → 230.88 ✓ EXACT. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com> |
