The validation report showed only the SAP calculator floor (calc(actual) vs lodged), so the headline PEI MAE (~40 kWh/m2) read as prediction error when much of it is the calculator's own API-path residual. Adds the CO2 + PEI floors alongside SAP. Diagnostic (150pc/514): PEI floor MAE 15.73 (calc(actual) vs lodged) vs SAP floor 1.57; calc(actual)/lodged PEI ratio ~1.06 (mean +10.7, ~+6% over- estimate). That RULES OUT the suspected gross unit/definition mismatch (a unit bug would be ~2x/3.6x, not 1.06) and reframes #1228: the PEI gap is a modest calculator bias (~16 floor, calc-branch) plus a larger prediction- sensitivity term (~24) — PEI is far more prediction-sensitive than SAP. CO2 floor 0.20 t. Script-only; no gate impact. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> |
