- Canonical mappingBinding of source-table columns to AEYS canonical fields (timestamp, energy, relevant variables) for a unit and energy carrier.
- Carbon Border Adjustment MechanismCBAMEU instrument that prices embedded carbon in selected imported goods; in Turkish regulation referred to as SKDM.
- Connector HubAEYS workspace for connecting plant or enterprise databases and exposing energy-relevant tables to canonical mappings and model training.
- Corporate Sustainability Reporting DirectiveCSRDEU directive requiring in-scope companies to publish sustainability information to European Sustainability Reporting Standards (ESRS), including energy and climate metrics.
- Cumulative sumCUSUMRunning total of period energy-saving values (actual minus expected). Sign indicates improving or worsening performance.

- Energy auditSystematic inspection and analysis of energy use and consumption of a site, equipment, system or organization to identify energy performance improvement opportunities.
- Energy baselineEnBQuantitative reference providing a basis for comparison of energy performance, often normalized for relevant variables.
- Energy carrierForm of energy supplied or consumed (electricity, natural gas, steam, diesel, compressed air) against which usage is accounted.
- Energy efficiency indexEEIRatio of actual energy consumption to expected (baseline) consumption. Values above 1 indicate worse performance than the model.
- Energy intensity indexEIIEnergy consumed per unit of economic value (for example TEP per currency of annual turnover).
- Energy management systemEnMSSet of interrelated elements that an organization uses to establish an energy policy, objectives, and processes to achieve those objectives.
- Energy performanceMeasurable results related to energy efficiency, energy use, and energy consumption.
- Energy performance indicatorEnPIMeasure or unit of energy performance, defined by the organization, used to monitor and demonstrate energy performance.
- Energy reference consumptionEnRCModel-predicted energy use for a SEU in a given period, used as the expected value in actual-versus-predicted tables.
- Energy reviewAnalysis of energy use and consumption based on measurement and other data, leading to identification of SEUs and opportunities for improving energy performance.
- Energy sourceCatalogued origin of energy for a unit or SEU (grid electricity, natural gas, fuel oil) used in operational control and report tables.

- ISO 14001ISO 14001International standard for an environmental management system, often operated alongside an ISO 50001 EnMS.
- ISO 14064ISO 14064Family of standards for quantifying, reporting, and verifying greenhouse-gas inventories and projects at organization level.
- ISO 50001ISO 50001International standard for establishing, implementing, maintaining, and improving an energy management system (EnMS).

- Management reviewPeriodic review by top management of the EnMS to ensure its continuing suitability, adequacy, effectiveness, and alignment with the strategic direction.
- Model trainingFitting an mf-python normalization model for a SEU from mapped or uploaded data so expected consumption (EnRC) can be predicted.
