WS1: Data Availability

Assessment Instructions

Participants must report this metric at the asset level.

GRESB automatically populates this indicator in the assessment response once participants have aggregated asset-level data from the Asset Portal.

When using the Asset Spreadsheet to upload asset-level data, GRESB recommends reviewing the instructions below in conjunction with the corresponding spreadsheet tab. The Cell Code column in the Input section indicates where to report each metric in the spreadsheet.

Input: How do I complete this metric?

Data	Cell Code	Instructions
Data Availability *Mandatory	E-F4	GRESB updated this section to provide additional clarity. For all guidance clarifications see here. Indicate the period for which consumption data was collected. For example, if data is available only for the last six months of a calendar year (January–December), the data availability columns should reflect July–December and follow the day/month/year format. Ensure that all performance data aligns with the reporting year specified in indicator EC4 (Reporting year). Data Availability might differ from the Ownership Period (Reporting Characteristics) in the following cases: If participants reported data for a shorter timeframe than their asset ownership period, Data Availability will reflect a shorter time than Ownership Period. If participants reported data from before the asset's purchase date, Data Availability will reflect a longer time than Ownership Period. For assets purchased during the reporting year, participants must input a Status (i.e., Standing Investment) in the previous year if they wish to report data from the previous year prior to the asset purchase. Guidance for unit consolidation - applicable to Residential Portfolios It is critical that values entered in the Data Availability fields represent and align with the reported performance data. If the consolidation of multiple units creates an inconsistency between the period of data availability and performance data reported, units must be reported separately. *Note: Data availability is only mandatory when the consumption and floor area covered are known.

Validation: What evidence is required?

This indicator is subject to automatic validation. No evidence is required. Refer to the page below for guidance on how to resolve automatic validation errors and warnings. Validation Basics

Scoring

Data availability influences the data coverage (2 points total) score calculation. Data availability must match an asset's ownership period for it to earn complete data coverage (time).
