Lancium Clean Campus
Financial, compute and water lenses come from engine run 78a2537c on the B ac chiller dry cooling prior. Carbon and lifecycle lenses are wired to the environmental layer of the same run and show PENDING until its factor and impact tables exist. Modeled counterfactuals are conditional on inferred as-found states; verified avoided impact requires a completed intervention with M&V.
What occurred during the reporting period, from meters, bills, BAS or service records.
What the defined baseline predicts for the same period — the engine's expected state at configuration, age, load and weather.
The difference attributable to a completed intervention under an explicit measurement-and-verification method, linked to the physical intervention, analysis run, baseline and measurement period.
A modeled alternative condition — if the inferred as-found state exists and the intervention is done. Never an achieved reduction.

Location-based and market-based Scope 2 are separate outputs; market-based is not implied to exist without procurement data. Avoided construction or deferred replacement is never booked as an inventory reduction.
Stationary combustion (generators), natural gas / direct fuels, refrigerant leakage and service, facility fuels.
Data centers: mainly generator testing and refrigerant service events.
Owner data needed Needs: generator run hours / fuel logs; refrigerant service records.
Purchased electricity × grid-average factor by geography and year.
ERCT (eGRID2023 subregion map: ERCOT All (Taylor County TX); classification by location), ERCOT / ERCO
Modeled Needs: electricity_emission_factors row for the subregion and year.
Purchased electricity × supplier-specific / contractual factors (PPAs, RECs, residual mix).
Only with procurement data; not implied to exist otherwise.
Owner data needed Needs: PPA / REC / supplier contracts.
Refrigerant type, charge, service additions/removals, leak events, recovery — GWP-version specific.
Chillers, CRAC units, dry coolers with DX circuits.
Owner data needed Needs: equipment register with refrigerant type and charge; service / leak records.
Withdrawal, consumption, make-up, blowdown, evaporation; intensity per IT kWh where useful.
Evaporative architectures only; dry heat rejection trades water for electricity.
Modeled Needs: make-up / blowdown meters; cooling architecture (owner).
Roofing, insulation, chillers, towers, pumps, electrical, batteries, servers, concrete, steel — upfront impact, service life, replacement cadence, end of life.
Every capital intervention; kept separate from inventory emissions (no avoided-construction credits).
Modeled Needs: EPDs / submittals; embodied factors with evidence quality.
Every intervention returns the same vector (engine spec §23.8). Financial, compute and water terms are the engine's; carbon and lifecycle terms are pending the environmental layer and are never approximated here. All rows are modeled counterfactuals on inferred as-found states.
