# GRESB Overview

> Integrated workflows and intuitive dashboards that simplify reporting.

## GRESB Partnership

In 2024, GRESB selected Abisko as its partner to develop a new toolkit designed to enhance the accuracy and efficiency of GRESB reporting via ENERGY STAR Portfolio Manager®. Launched in 2025, the GRESB Toolkit has transformed reporting for GRESB members and partners by streamlining workflows, reducing costs, and delivering greater data accuracy.

### Review Process

Abisko worked directly with GRESB staff to review all methodologies, algorithms, and assumptions driving performance, gap-filling, green power, emissions, and data availability calculations. This process ensures that the platform provides the accurate GRESB submissions that fully align with official reporting guidelines.

## GRESB Workflows

Abisko simplifies GRESB reporting via intuitive dashboards that help users track reporting readiness, understand data quality and performance trends, identify opportunities to improve scores and prepare submission-ready Asset Level Spreadsheets. Integrated workflows enable users to:

* Track the collection of property characteristics required for GRESB
* Set reporting levels and define landlord and tenant spaces
* Assign meters to spaces and resolve data quality & completeness issues
* Report performance and validate data coverages across spaces and utilities
* Manage measures, assessments and certifications across portfolios

### Property Level

**Navigate to Property → GRESB**

Users can track reporting readiness for a property by using the reporting progress panel located on the left-hand side of the GRESB tab. The panel is displayed by default but can be hidden by clicking the small left arrow in the top-right corner.

Within the panel, users can quickly see which GRESB subtabs for the property still need to be reviewed. Users can also click on the name of any section in the panel to quickly jump to the corresponding GRESB subtab.

### Portfolio Level

**Navigate to Portfolio → GRESB**

Users can also track reporting readiness at the portfolio level using the reporting progress panel. Each progress bar represents the percentage of properties in the portfolio for which the corresponding GRESB subtab has been marked as **Closed**. For example, if the *Spaces* bar shows 75% complete, this indicates that users have entered data for the Spaces subtab and manually marked it as Closed, for 75% of properties in the portfolio.

This progress panel enables users to quickly identify which properties have been reviewed and finalized, and which still require attention during the GRESB reporting season.

### Annual Resets

The **GRESB Reporting Year**, displayed in the reporting progress bar on the left side of each GRESB page, automatically updates on January 1 of each calendar year. For example, on 1/1/2026, the Reporting Year updated to 2025 and the Prior Year to 2024, ensuring that all GRESB data and trend views reflect the most current reporting period.

The reporting status for each category in the progress bar also automatically resets to **Open** at the start of the new year, allowing users to restart the data collection and verification process across their properties. Applicable data, however, is retained.

## Bulk Imports & Audit Reports

Users can leverage bulk import templates to add and update certifications, measures, space definitions, meter assignments, data coverages, and more GRESB data types across their properties. A variety of [EXCEL reports](/reports/index), including the [GRESB Audit Report](/reports/gresb-audit), also enable users to track reporting readiness across large portfolios.
