Validation: Quantitative

Automatic data validation

Automatic Data Validation

The GRESB Portal has a built-in automatic validation system that flags inconsistencies as participants complete their assessment response.

Scope: What is automatically validated?

Automatic validation consists of errors and warnings displayed in the GRESB Assessment for entity-level responses to ensure that all quantitative data input is complete and accurate.

Criteria: What checks are conducted?

General Requirements

• Information completeness: The portal ensures mandatory evidence uploads are present, that all required open text boxes are completed, and that answers are provided for all indicators.

• Data types: Certain fields must adhere to specific data types, such as numbers, percentages, text, etc.

• Information accuracy: percentage values must range between 0 and 100, and metrics are restricted to absolute values (i.e., only non-negative numbers).

Outcomes: What are errors and outliers, and how are they handled?

Errors

Errors appear in red and are generated per assessment as a result of logical checks amongst the different data fields in the assessment response.

Participants cannot submit their assessment until all validation errors are resolved.
