  "selection": "Reuse the original substantive utility cascade with documented corrections. Independently harden the unfinished hourly dispatch candidate; no completed newer PowerPlan release was evidenced. Replace unsupported standards/accreditation claims with explicit review requirements.",

    "Lighting/plugs/apron W to kW conversion",
    "Thermal cooling divided by entered COP",
    "EV and pad loads included in annual demand",
    "SAF is a component of total fuel throughput; storage quantities do not double count it",
    "Reuse limited by non-potable demand and treated wastewater supply",
    "Storage service envelopes are alternatives, not additive capacity requirements",
    "Hourly PV/load/storage conservation with explicit curtailment and final stored energy",
    "Grid emissions from hourly imports; kg, t and kt conversion corrected",
    "USD, thousand USD and million USD scale corrections; nominal lifecycle discounting",

    "electrical": "Lighting 9 W/m², plugs 13 W/m²; apron 1.8 W/m² plus 1 MW; diversity 0.72, headroom 1.20; COP editable; full-load hours by end use",
    "solar": "Terminal roof fraction plus parking × 12 m² × 0.7 and max(apron × 0.05, terminal × 0.3) assumed ground area; 0.18 kWp/m²; land/roof feasibility must be evidenced",

    "water_reuse": "80% passenger/F&B return flow, 90% recovery, capped by cooling + irrigation demand; STP adds 30% headroom",
    "battery": "Usable AC-connected storage, square-root charge/discharge efficiencies; empty start; no reserve, grid charging, degradation or dispatch optimisation",
