Simulated Asset Scoring
Bring GRESB scoring logic into your investment decisions.
Introduction
Simulated Asset Scoring models how asset-level performance and portfolio changes translate into simulated GRESB scoring outcomes—before submission.
Simulated Asset Scoring is coming soon. Register your interest here.
What can fund managers do with the tool?
With it, fund managers can:
Preview likely scoring impact of asset-level changes
Understand how the portfolio may perform under the current methodology before official submission
Identify score drivers early
See which assets have the greatest influence on simulated scores
Prioritize improvements before the reporting season
Focus efforts where performance changes may shift outcomes
Evaluate portfolio moves with scoring visibility
Anticipate how acquisitions, disposals, and upgrades may affect future results
Instead of discovering outcomes after submission, participants engage with scoring implications when there is still time to act.
What is the scope of the tool?
In its initial release (May 2026), the Simulated Asset Scoring tool will cover all valid assets classified as standing investments and scored under the performance component in the GRESB Real Estate assessment, for Energy (EN1), GHG (GH1), Water (WT1) and Waste (WS1). It represents a total of 32 points of the score.
The simulation coverage will be extended in future releases, including Building Certification (BC1) and Energy Ratings (BC2), totaling an additional 10.5 points.
Access the Dashboard
Navigate to the Simulated Asset Scoring tab
Within the Asset Portal, click the "Score Simulation" button next to "Asset Analytics" to open the dashboard.
Users will only be able to access Simulated Asset Scoring of reporting entities for which it has been purchased. Contact GRESB for more information.
Note that only users with Account Manager, Internal Contributor, or Investor Relations Manager access rights can view Simulated Asset Scoring. External Contributors will not have access.
Ensure data is valid and complete for simulation
Two criteria must be met for the GRESB Portal to generate the dashboard:
All assets that are operational during the reporting year must be free of errors.
If operational assets (i.e. assets classified as Standing Investments) have errors, return to the Data Management tab to resolve them. Development assets are outside the scope of Simulated Asset Scoring.
The % Gross Asset Value (GAV) per property sub-type and country is available and reflects the most recent asset-level data in the Data Management tab.
I provide GAV at the asset level. What do I do?
If GAV has been provided for all assets that are standing investments during the reporting year, you can go straight to Score Simulation. The dashboard should open automatically. If you select View % GAV, you’ll see the % GAV table already populated based on your latest asset-level data in the Data Management tab. You can keep the pre-filled values or update them if needed.
If asset-level GAV is incomplete or outdated, you should complete the % GAV table within the Simulated Asset Scoring tab. You will not be able to proceed until the table is complete (i.e., the total GAV is 100%).
I provide GAV at the property sub-type and country level in indicator R1. What do I do?
Select Pre-fill from Assessment to import the % GAV values you already entered in R1 (Entity’s Standing Investments Portfolio During the Reporting Year). This works when R1 is complete, including % GAV, and the property sub-type and country combinations match between the Assessment and Asset Portal data. If they do not match, the button is unavailable or greyed out.
My asset data changed after I already had % GAV values. What do I do?
If your asset updates did not create any new property sub-type/country combinations, the dashboard should still load, but you may see a warning that your % GAV could be outdated.
Review the table and update it if needed so it reflects your latest asset-level data. If your changes created new property sub-type/country combinations, you’ll need to complete the % GAV table again before running the simulation.
The % GAV values entered in Simulated Asset Scoring are used only for score simulation purposes. They are not transferred to the GRESB Assessment.
You can import % GAV values from the Real Estate Assessment into Simulated Asset Scoring, but values entered or updated in Simulated Asset Scoring cannot be exported back to the assessment.
Use the Dashboard
How does GRESB calculate simulated scores?
Using the latest scoring model
Simulated Asset Scoring uses the current year scoring model.
In practice this means:
The current-year simulated scores are based on the same scoring model that will be used for that year's results.
Ahead of the next assessment year, GRESB will update the tool to use the next year's scoring model.
Based on the most recent benchmark
Simulated Asset Scoring uses most recent GRESB Benchmarks.
In practice this means:
Until the current year's results are released (October), GRESB applies benchmarks from the previous year.
Once the current year's results are released (October), GRESB will update tool with the current year's benchmarks.
What does the dashboard include?
Upon opening the dashboard, users will find an Overview tab that captures Energy, GHG, Water, and Waste scores.
Navigate between tabs to explore each Aspect to see more detail on its underlying performance metric scores (e.g., data coverage).
It is also possible to export the data to a .csv or .xlsx file.
For display purposes, GRESB rounds the values in the Simulated Asset Scoring dashboard to one decimal point. Any difference between the sum of Aspect scores and the total Simulated Score is due only to display rounding.
Filters
Users can apply the following filters for more targeted dashboard insights:
Score Display
Points: Displays values in GRESB score points to show how each element or asset contributes to the overall GRESB score. Use this to understand impact on the final score.
Percentage (%): Converts the point values to a 0–100 scale, expressed as a percentage of the maximum possible score. Use this to understand the portfolio’s performance relative to its full potential.
Asset Name
Select an individual asset to isolate its simulated scores. It is not possible to select multiple assets.
Property Type & Location
Select any combination of property type(s) and location(s).
Simulated Score Overview
Donut charts display aggregated estimated scores calculated using the % GAV values provided in Simulated Asset Scoring.
In line with GRESB methodology, asset-level scores are first aggregated to each property sub-type and country combination, and those aggregated results are then weighted using the relevant % GAV values to calculate the donut chart scores.
If you change the % GAV values, the donut chart results will change accordingly because the portfolio weighting has been updated.
Performance Overview
Each bubble is an asset. Hover over a bubble for the asset score, contribution, potential and weight. Values are estimates that reflect live Data Management inputs, the scoring model and benchmarking values used for the simulation.
Clicking on any of the bubbles will filter the dashboard's display insights for the selected asset only.
Asset Score: The total score for each asset, expressed either as points or percentage.
Bubble size: Asset weight in the portfolio (larger = bigger impact).
Asset Weight: Determines the contribution of an asset’s individual score to the overall portfolio score. In line with GRESB's methodology, asset weight is calculated by using a combination of:
the % GAV assigned to the relevant property sub-type and country, and
the asset’s share of total floor area within that same property sub-type and country, adjusted for ownership share and the duration of ownership during the reporting year.
For indicators where only some assets are eligible (such as Energy Performance, GHG Like-for-Like, and Water Like-for-Like) the asset weight is calculated based only on the total floor area of eligible assets within that property sub-type and country grouping.
Asset Weight Formula: (% GAV of country / property sub-type) * (asset floor area * asset ownership % * ownership period) / (floor area * ownership of all assets in country / property sub-type)
Contribution = points currently contributed by the asset. It is calculated as:
Asset Weight (%) * Asset Score
Potential = remaining points the asset could contribute (maximum points − points currently contributed).
