Energy & Water Data Coverages

Energy data coverages can be concurrently tracked for both the Whole Building and across all Spaces. The values reported to GRESB depend on the Reporting Level.
  • If Reporting Level = Whole Building (Any) → Whole Building data coverages are reported
  • If Reporting Level = Split (Landlord/Tenant) → Spaces data coverages are reported

Water data coverages are tracked and reported the same way as energy data coverages.

GHG Data Coverages

GRESB GHG data coverage calculations for Scope 1,2,3 emissions depend on the Energy Reporting Level of each property and can be complex due to differing floor area values across energy coverages. The following examples demonstrate how Floor Area Covered and Max Floor Area values are calculated for the Asset Level Spreadsheet.

​
Reporting Level = Whole Building (Landlord Controlled)

Example whole building data coverages by utility type:
Utility TypeFloor Area CoveredMax Area CoveredData Coverage
Electricity20,000 ft220,000 ft2100%
Fuel10,000 ft215,000 ft266.67%
District Heating & Cooling10,000 ft218,000 ft255.55%
TOTAL ENERGY40,000 ft253,000 ft275.47%
Scope 1 Data Coverage
  • Max Area Covered = FUEL Max Area Covered
  • Floor Area Covered = FUEL Floor Area Covered
Scope 2 Data Coverage
  • Max Floor Area = MAXIMUM (ELEC Max Area, DHC Max Area)
    • MAXIMUM (20000, 18000) = 20,000 ft2
  • Energy Coverage % = SUM (ELEC Floor Area, DHC Floor Area) / SUM (ELEC Max Area, DHC Max Area)
    • SUM (20000, 10000) / SUM (20000, 18000) = 78.9%
  • Floor Area Covered = Max Floor Area * Energy Coverage %
    • 20,000 ft2 * 78.9% = 15,789 ft2
Scope 3 Data Coverage
  • N/A (All emissions are from landlord controlled meters)

​
Reporting Level = Whole Building (Tenant Controlled)

Scope 2 Data Coverage
  • N/A (All emissions are from tenant controlled meters)
Scope 3 Data Coverage
  • Max Floor Area = MAXIMUM (ELEC Max Area, FUEL Max Area, DHC Max Area)
    • MAXIMUM (20000, 15000, 18000) = 20,000 ft2
  • Energy Coverage % = SUM (ELEC Floor Area, FUEL Floor Area, DHC Floor Area) / SUM (ELEC Max Area, Fuel Max Area, DHC Max Area)
    • SUM (20000, 10000, 10000) / SUM (20000, 15000, 18000) = 75.47%
  • Floor Area Covered = Max Floor Area * Energy Coverage %
    • 20,000 ft2 * 75.47% = 15,094 ft2
