The following guidance can now be used to interpret the meaning of the asset footprint:
Building only:
- The asset is a building on its own without any associated site attached to it (for example an office tower in a city centre). In this case, the asset footprint can be considered to be the area of the asset/building only, typically the ground floor area.
- Planting, including roof- and or vertical planting, on the asset/building that is under assessment must be included in the calculation.
Building located on a site:
- The asset footprint can be taken as the site on which the building is situated. The boundary of the site must be drawn when either:
- Responsibility of management or ownership of the site changes; OR
- If a site includes multiple assets and there is a clear demarcation of the area associated with each asset, then this must be considered to be the site boundary for the asset footprint.
- The footprint of any asset that is on the site but does not form part of the assessment will be deducted from the asset footprint.
- Planting, including roof- and or vertical planting, on the asset/building that is under assessment must be included in the calculation.
- Planting, including roof- and or vertical planting, on other assets/buildings than the one under assessment must be excluded from the calculation.
Calculation methodology for LE01
Percentage planted area = [Total area planted (m²) / Asset footprint (m²)] x 100
GdT 08/12/16 - Added additional guidance on deducting area from asset footprint.
