Session landed three spec-clean slices closing four major residuals: - S0380.153 (Table 3 middle row for solid-fuel boilers): SF3 EXACT all 4 metrics (+0.30 → -0.0000). Found the rule that solid-fuel boilers don't ship with dual programmers per §9.2.4. - S0380.154 (§12.4.4 back-boiler summer-immersion): SF2 SAP+cost EXACT (+1.86 → -0.0000 SAP; -£42.84 → -£0.00 cost). Implemented HW fuel kWh split + monthly blend across cost / CO2 / PE / standing. - S0380.155 (Table 4a HP water-column dispatch): gshp closed ±0.02 SAP (+0.94 → -0.0178). HW kWh 841 → 1138 matches worksheet exactly. Σ |ΔSAP_c| 14.5 (session start of S0380.150) → 2.7 = 81% reduction across 6 slices, two sessions. Handover doc captures: - Per-line discipline (walk worksheet before forming hypothesis) - Elmhurst-vs-spec divergences to defer (lighting-PE +48.66 cluster uses Table 12 annual factor; spec Table 12d mandates monthly) - Ranked open fronts (electric 5 R=0.20 storage MIT, electric 2 warm-air HP HW, deferred lighting-PE cluster) Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com> |
