ESG SDDS Wiring-Guide

"Estimated operational energy consumption for the proportion of portfolio that is in tenant’s control. In the absence of actual data, energy use can be estimated based on building characteristics and publicly available data using commercial databases - see PCAF, and/or linear extrapolation could be applied - see CRREM (ref: GRESB)."
 

"The same recognised estimation approaches described in ESG3.1.3 (landlord-controlled areas) apply here, adjusted for tenant-controlled areas (see ESG3.1.1 for control type classification).

In summary, estimation should only be used where actual data cannot be obtained, and reported in kilowatt hours (kWh). Managers may apply PCAF-based methods (e.g. energy label and floor area, statistical benchmarks, or per-building averages) or CRREM-based extrapolation when partial-year data are available.

Note 1: In line with GRESB, estimated data should not exceed 20% of the portfolio’s total reported energy consumption coverage.
Note 2: The ESG SDDS does not prescribe a fixed reporting frequency. Data may be collected and reported annually or quarterly, depending on manager and investor practices. Quarterly data provides faster insight (e.g. for SFDR or interim steering) but may face challenges such as incomplete invoices, tenant privacy restrictions, or the need for interim estimations.
Note 3: Clearly document the estimation method, data sources, and assumptions to ensure transparency and comparability over time."
