Assets with non-vegetated surface, data coverage (% of area)
Definition:
This data field is provided for comparison purposes and not a recommended KPI within the INREV Guidelines. The floor area percentage of the vehicle for all assets with non-vegetated surface. This is calculated based on the amount of space divided by total supply area. Recommended unit of measure for data coverage is by area (ESG1.6.1: sqm/sqf), investment managers may identify and report KPIs on value (AUM basis). Please also consider the availability of data for the period of time for which assets are owned by the vehicle (ref: GRESB).
Additional Guidance:
To calculate coverage, divide the total floor area of assets with complete and reliable non-vegetated surface data by the total supply floor area (ESG1.6.1), then multiply by 100.
Data sources may include site plans, GIS mapping, architectural drawings, or on-site surveys. Where only partial site data is available, coverage should reflect the proportion of assets for which non-vegetated surface data is complete.
Note 1: Use the total supply floor area as defined in ESG1.6 (Total Area) to ensure consistency with other coverage indicators.
Note 2: Data coverage may also be calculated on an AUM basis, provided the methodology is applied consistently across the portfolio.
Note 3: Where coverage is partial, disclose the limitations (e.g. lack of site-level data, outdated surveys, unclear plot boundaries).
