GRESB has approved the PERFORM verification letter from GBCI to support GRESB certification, allowing to earn up to 5 points to the project scorecard. PERFORM, which focuses on operational performance, supports the data for the Monitoring and Review (MR) section of the GRESB scorecard. It can be recognized as ‘externally assured’ following a successful review and limited assurance engagement with GBCI.
| PERFORM PERFORMANCE METRIC | GRESB | |
| INDICATOR | MAX SCORE | |
| Total Energy Use And Energy Use Intensity | MR1: External Review Of Energy Data | 1.75 |
| Total GHG Emissions And GHG Emissions Intensity | MR2: External Review Of GHG Data | 1.75 |
| Total Water Use And Water Use Intensity | MR3: External Review Of Water Data | 1.25 |
| Total Waste Diversion | MR4: External Review Of Waste Data | 1.25 |
Data Assurance for GRESB
For GRESB assessments, data assurance is an essential part of the process. To ensure the accuracy and reliability of the performance data, companies must undergo an external verification or review by an accredited third-party organization. This review involves assessing the sustainability metrics reported, such as energy use, water consumption, waste management, and carbon emissions, to confirm that the data is accurate, consistent, and aligned with GRESB’s criteria.
The collaboration with PERFORM simplifies this process. The portfolio manager can set the thresholds and gain the desired assurance, ensuring that sustainability data is thoroughly verified and meets GRESB’s standards.
Seamless Data Flow With Monitoring Platforms
For real estate portfolios with real-time building performance monitoring systems, achieving ESG goals is becoming even more streamlined. Look how continuous data can now be verified for globally recognized reporting:
- Performance Monitoring System (e.g., BEE Sense) continuously tracks key sustainability metrics.
- PERFORM verifies and consolidates the data, ensuring it aligns with GRESB’s Monitoring and Review criteria.
- GRESB recognizes the PERFORM-assured data, enabling projects to earn up to 5 additional points in the assessment.
Since PERFORM also complements LEED, using monitored data along with PERFORM is an efficient way to improve operational performance, achieve green building certifications, and streamline ESG reporting—all at once. Asset owners and managers can confidently meet their sustainability goals and demonstrate progress with reliable data.
