Cambio consolidates meter-level energy data across all property energy sources, normalizes inputs using standardized conversion factors, and applies estimation methods to address data gaps. The platform distinguishes between location-based and market-based renewable energy consumption and produces consistent, auditable energy metrics used as inputs for energy, emissions, and carbon intensity calculations.
Total electricity consumption | Total electricity consumption is aggregated from meter-level data for all electricity meters at the property. For buildings with mixed grid and onsite solar electricity, total consumption is the sum of both sources. |
Total Fuels | Following the Data Completeness and Estimations energy method, Total fuels is aggregated from meter‑level data for all fuels meters at the property (e.g., natural gas, fuel oil, diesel, propane). Presence and subtype of fuels are attributed at time of upload and used to normalize to fuel unit using standard higher‑heating‑value factors. Per fuel estimation is used to address meter gaps for each fuel type by the property. |
Total District Energy | Total district energy is aggregated from meter‑level data for all district energy meters at the property (steam, hot water, chilled water). Presence and subtype are attributed at the time of upload. All inputs are normalized to standard energy units using standard factors for the recorded unit type (e.g., kBtu or MMBtu 1:1 to kBtu, pounds of steam via standard steam enthalpy, ton‑hours via chilled‑water conversion). |
Renewable Energy Consumption - Location Based | Total energy consumption from renewable sources based on grid mix data (solar, wind, hydro, geothermal) plus any on-site renewable generation. |
Renewable Energy Consumption - Market Based | Total energy consumption from renewable sources accounting for contractual instruments such as renewable energy certificates (RECs), power purchase agreements (PPAs), and green tariffs. Reflects the organization's purposeful energy procurement choices. |
Total Energy Consumption | This is the sum of all energy types (electricity, natural gas, fuel oil, etc.) across all active meters at the property. |
Landlord and Tenant Allocation
To support asset-level reporting and ensure consistent attribution of utility consumption, meters onboarded into the Cambio platform are classified according to the building area served and the applicable lease structure. Meter classification enables the allocation of energy consumption between landlord-controlled and tenant-controlled areas in a transparent and reproducible manner.
Each meter is tagged during the onboarding and data review process based on information provided by the property manager regarding the metered space and lease configuration. Meter tags determine how energy consumption is attributed within the building and how landlord and tenant energy use are calculated for reporting and analysis purposes. Meters fall into one of three allocation categories: Landlord (consumption attributed entirely to Scope 1 or Scope 2), Tenant (consumption attributed entirely to Scope 3, Category 13), or Shared (whole-building meter where consumption is allocated between landlord and tenant using floor-area proration, with the tenant share reported as Scope 3 Category 13 and the landlord share reported as Scope 1 or Scope 2, as applicable). Meter classification and allocation rules are maintained within the Cambio platform and applied consistently across all assets. Any updates to meter tagging or asset floor-area configuration automatically propagate through downstream calculations to ensure that landlord and tenant energy allocations remain synchronized with the most current building metadata.
Calendarization
Utility bills spanning non-calendar billing periods are converted into a calendar-month time series using day-weighted allocation. This produces one consumption value per meter per calendar month, enabling consistent year-over-year comparison and ensuring that scope allocation and GHG calculations are applied on a standard reporting cadence.
