EN1: Energy Consumption

Intent

Energy consumption accounts for a large share of a building’s environmental footprint. Data measurement and consistent reporting of energy consumption help entities to conceptualize overall energy consumption, increase the energy efficiency of their portfolio, and reduce economic and environmental impacts associated with fossil fuel energy use.

Requirements

The indicator below is automatically populated by GRESB based on information provided through the reporting entity’s GRESB Asset Portal. Participants can access the Asset Portal via the Assessment Portal menu, section ASSETS.

The table above is automatically populated by GRESB based on information provided at the asset level by the GRESB participants through the GRESB Asset Spreadsheet. It displays the total area size reported in the Energy tab, split by floor area types.

Total energy consumption of the portfolio

The table above is automatically populated by GRESB based on information provided at the asset level by the GRESB participants through the GRESB Asset Spreadsheet. It displays the aggregated Energy consumption values per property type, along with their related Floor Area Covered, Maximum Floor Areas and Like-for-like consumption changes (%)

Total data coverage of the portfolio

The table above is automatically populated by GRESB based on information provided at the asset level by the GRESB participants through the GRESB Asset Spreadsheet. It displays a summary of aggregated Data Coverages and Like-for-Like consumption changes per property type, split by Landlord Controlled and Tenant Controlled areas. While “Area - Aggregated Data coverage” only accounts for the floor area size of assets when aggregating values, “Time - Aggregated Data coverage” accounts for the period of ownership. Consequently, “Area/Time - Aggregated Data coverage” aggregates both dimensions and is used for benchmarking purposes.

Renewable energy generated

The table above is automatically populated by GRESB based on information provided at the asset level by the GRESB participants through the GRESB Asset Spreadsheet. It displays the aggregated Renewable Energy consumed/generated per property type, either on-site or off-site, as well as the Percentage of total Consumption by category.

________________________

In 2020, participants are required to report their energy consumption and renewable energy usage at the asset level, using the GRESB Asset Spreadsheet. See tab Instructions for detailed guidance on how to interpret and complete each field.

It is recommended to:

• Prepare and upload the GRESB Asset Spreadsheet into the Assessment;
• Review all fields in EN1 to ensure it is accurate and complete.

Estimates: When landlord-obtained annual consumption data for a particular energy source is partially unavailable or unreliable for an asset, estimations may be necessary. Estimation allows the completion of annual data to be calculated for an asset where data is partially missing or unreliable. GRESB allows participants to use estimated data when reporting on energy consumption if this is aligned with one of the predefined methodologies (see Appendix 7) and not used as a substitute to gather complete and accurate data.

Data coverage calculations: GRESB calculates Data Coverage based on floor area for which consumption data is available and on the total floor area for which consumption data could have been collected, which is the total supply area. Data Coverage is calculated separately for Whole Building, Base Building and Tenant Space.

Validation

This indicator is subject to automatic validation.

See Appendix 2a for additional information about GRESB Validation.

Scoring

14 points, E

The score of this indicator equals the sum of the scores achieved by:

1. Data coverage = 8.5 points;
2. Like-for-Like data availability = 0.5 points;
3. Like-for-Like performance improvement = 2 points;
4. Renewable energy = 3 points. The renewable energy score is split as follows:
   • On-site renewable energy = 1 point;
   • Off-site renewable energy = 0.5 points;
   • Performance = 2 points.

Open text box: The open text box is not scored and is for reporting purposes only.

See the Scoring Document for additional information on scoring.

Terminology

See definitions in Appendix 9b and in the Instructions tab of the GRESB Asset Spreadsheet.

Data Coverage: The part of the asset for which data is available, per space and energy type. The floor area reported in these fields reflects the floor area of the portfolio for which Absolute Consumption data is collected from.

Note: If the floor area for common areas is unknown, report an estimated floor area as a proportion of lettable floor area. Participants who do not track the gross floor area of their assets can use the estimated intervals proposed in Appendix 3a to calculate the size of their common areas. Report the details of the estimate in the open text box below the Energy Consumption Table.

Like-for-Like (LFL): Figures that only include comparable data points from two consecutive reporting periods. Only assets that meet all of the following criteria, for both current and previous reporting years, are eligible for inclusion in the LFL calculations:

• Data Availability covers the full year (> 355 days);
• Data Coverage is positive;
• Data Coverage is the same (within 1% error threshold);
• The asset is classified as Standing Investment.

Percentage renewable energy: The percentage of the whole portfolio’s total energy use that is sourced from renewable energy. This is calculated based on (a) the total amount of renewable energy and (b) total energy consumption of the whole portfolio, per property type.
