The Scaler Platform automatically triggers three types of alerts to help guide your data input process and ensure reporting accuracy.
You can filter the Asset-level view in the Data Collection Portal by both Alert type and Report to prioritize your attention effectively.

1. Errors
Definition: An error occurs when data entered does not meet the input requirements for a specific field, violates validation rules, or fails to align with reporting framework logic.
Examples:
- General:
- The
Covered areaof a meter exceeds the available floor area for itsArea type. - Overlapping consumption date ranges within a meter.
- Report-specific (e.g., GRESB):
- Whole building meters must have consistent operational control (landlord vs. tenant) across all resource categories.
Impact:
Errors prevent completion of the reporting use case and lower your Scaler Data completion percentage. When Scaler Data completion is below 100%, Scaler cannot run or update metric calculations in the background — meaning metrics may not display at all or appear outdated. To unlock accurate and up-to-date metrics, all errors must be resolved and Scaler Data completion must reach 100%.

2. Missing data
Definition: Required fields have been left empty, either for running analytics or auto-generating reports.
Categories:
- Scaler analytics:
- Missing required fields like
Gross floor area,Common area, orTenant areaprevent the calculation of metrics such as data coverage and intensities.
- Reporting outputs:
- Missing required inputs for frameworks like GRESB, GRI, or EU Taxonomy.
- Example:
Percentage greenis required under Meter details for GRESB.
Important distinction: “Missing data” alerts do not refer to gaps in consumption data for a meter or asset. These are addressed through Data coverage.
Impact:
Both Errors and Missing data alerts must be resolved for Scaler Data completion to reach 100%, which is required for up-to-date metrics. Until resolved, data in the Asset > Overview table may be incomplete or outdated.

3. Warnings
Definition: Warnings alert users to values that may require further review or verification.
Two main types:
- Data integrity checks:
- Consumption date range precedes the
Meter version start dateor the asset’sOwned sincedate. Scaler normalizes consumption for this (unless specified otherwise for a specific report) but flags it for review. - Both
Whole buildingand individualTenant+Common areameters are entered, potentially duplicating coverage.
- Outliers in consumption values:
- Significant year-over-year change in resource consumption (energy, water, or waste) triggers a warning.
- These are calculated based on the relative change.
- A warning is generated if the result falls outside the range of [-0.5, 1.0], aligned with GRESB’s methodology (normalized for occupancy and reporting period).
Note:
Correct values may still trigger a warning. Users can manually clear the alert by selecting Remove warning if verified.
Visibility:
Outlier warnings only appear when the Scaler report filter is applied. They are hidden when viewing alerts for other reporting frameworks.


Resolving Alerts
- Go to Data Collection Portal → Asset-level view → Overview.
- Click on a specific report (e.g., Scaler, GRESB) in the calculation bar to filter the asset table for assets with relevant alerts.
- Use the Alert type filter to narrow down to Errors, Missing data, or Warnings.
- Assets are sorted by Scaler Data completion by default, with those <100% at the top.
- Click the pencil icon to Edit an asset. Alerts are listed in the left-hand menu by section.
- Hover over the alert icon next to a field to view contextual guidance on how to resolve the issue.
