Introduction: Continuing Our Series on PRA + Green Building Certifications & Frameworks
As climate risks accelerate and disclosure expectations evolve, investors, owners, and managers are increasingly turning to ESG frameworks to demonstrate responsible stewardship of real estate assets. At Nova Group, GBC, we believe true building performance integrates both resilience and wellness. In our Resilience Meets Sustainability series, we’re exploring how Property Resiliency Assessments (PRAs) enhance leading green building certifications and frameworks. In earlier parts of our Resilience Meets Sustainability series, we explored how Property Resiliency Assessments (PRAs) reinforce building-level certifications such as LEEDv5, BREEAM USA, Green Globes (EB), and WELL v2.
Now, in Part 5, we turn to GRESB (Global Real Estate Sustainability Benchmark)—the most widely used ESG and sustainability reporting platform in the real estate sector. We examine how PRAs directly strengthen GRESB’s Management Component, Performance Component, and especially the Resilience Module, helping organizations demonstrate leadership in climate risk mitigation, adaptation, and governance.
GRESB: A Global Benchmark for ESG & Resilience Performance
GRESB is a global standardized reporting framework used by real estate investors, REITs, private equity funds, and asset managers to measure ESG performance, benchmark portfolios, and communicate risk posture to capital partners. The framework focuses on three pillars:
Management – Policies, risk processes, oversight, and stakeholder engagement
Performance – Energy, emissions, water, waste, certifications, and building-level actions
Development – ESG integration for new construction or major renovations
GRESB also evaluates resilience through specific indicators that assess how organizations identify, assess, manage, and monitor climate-related risks.
Although not a building certification system, GRESB is placing greater emphasis on climate risk governance, physical risk assessment, and transparent disclosure. PRAs provide the detailed analyses and documentation that strengthen reporting in all of these areas.
What is a Property Resiliency Assessment (PRA)?
A PRA evaluates a property’s exposure to climate hazards—such as extreme heat, flooding, high winds, drought, and wildfire smoke—as well as operational vulnerabilities like power disruptions and gaps in emergency preparedness. Its purpose is to understand how these risks may affect a building’s ability to remain safe and functional during disruptive events.
Following ASTM E3429-24, a PRA analyzes hazard exposure, vulnerability, and adaptive capacity, and reviews site conditions and building systems to identify both strengths and areas of concern. It also outlines targeted strategies to address identified risks.
By summarizing risks, documenting existing measures, and providing clear recommendations, PRAs help owners integrate resilience into capital planning and operations. This clarity strengthens resilience planning at both the property and portfolio level and directly supports GRESB reporting expectations.
Where PRAs Directly Strengthen GRESB Reporting
Several GRESB indicators align precisely with what a Property Resiliency Assessment delivers. Below are the four most direct crossover points—each of which can be supported or fully satisfied through a PRA aligned with ASTM E3429-24.
Management
RM5 - Climate Resilience
RM5 focuses on how an organization monitors and maintains its understanding of climate-related physical risks over time. PRA methodology includes reassessment cycles, triggers for updating risk information, and systems for tracking implemented resilience measures—directly supporting RM5’s emphasis on ongoing monitoring, governance processes, and adaptation over time. PRA outputs provide the documentation GRESB expects to verify that climate resilience is being systematically evaluated and integrated into property and portfolio management.
RM6.3 - Physical Risk Identification
RM6.3 requires entities to identify the full spectrum of physical climate risks relevant to their portfolio. A PRA performs exactly this function by screening for acute and chronic hazards such as extreme heat, flooding, high winds, storm surge, wildfire, and drought. Using geospatial data, hazard maps, modeling tools, and authoritative datasets, PRAs offer the defensible risk identification needed to satisfy GRESB’s requirement for transparent and methodologically sound risk identification.
RM6.4 - Physical Risk Impact Assessment
RM6.4 evaluates whether the entity has assessed the potential impacts of identified physical risks on assets and operations. A PRA goes beyond hazard mapping to evaluate exposure, sensitivity, adaptive capacity, and the likely operational consequences of climate events—such as systems failure, business interruption, loss of habitability, or health and safety impacts. PRA findings directly address RM6.4’s expectations for impact assessment by translating hazard exposure into real implications for building systems, occupants, and financial performance.
Performance
RA1 - Risk Assessments Performed on Standing Investments Portfolio
RA1 evaluates whether an entity has conducted a structured physical risk assessment across its standing investment portfolio. A PRA is, by definition, an asset-level physical climate risk assessment using a standardized methodology. It identifies relevant hazards, evaluates exposure and vulnerability, and documents existing and recommended resilience measures. Completing PRAs across all or a subset of assets provides the formal evidence GRESB requires to demonstrate compliance with RA1 and substantiate the scope and depth of the assessment process.
Additional Synergies
Beyond the indicators where a PRA provides direct evidence, several other areas of the GRESB Standard benefit from PRA insights. While these indicators do not explicitly require a physical climate risk assessment, PRA findings help strengthen the quality, completeness, and credibility of the information reported.
PRA outputs support Leadership (LE) and Policies (PO) by grounding ESG commitments and resilience policies in objective, site-specific risk data. They inform Reporting (RP) by supplying hazard maps, vulnerability summaries, and adaptation plans that can be incorporated into annual ESG disclosures and TCFD-aligned reporting. PRA findings also contribute to Stakeholder Engagement (SE) by identifying vulnerable populations, continuity needs, and communication requirements during emergencies. Within the Performance component, PRAs indirectly strengthen indicators related to Targets (T1), Data Monitoring & Review (MR), and Building Certifications (BC) by guiding resilience-focused performance goals, defining critical monitoring needs, and clarifying which assets may benefit most from green building certifications that include resilience features.
While these synergies do not represent direct indicator scoring, they enhance the consistency, defensibility, and strategic alignment of an organization’s broader GRESB submission.
Why This Crossover Matters
Pairing PRAs with GRESB reporting provides statistically and operationally meaningful benefits:
Higher GRESB Scores: PRAs help satisfy multiple scored indicators across Management and Performance categories.
Stronger ESG Narratives for Investors: GRESB participants must demonstrate physical risk governance. PRAs provide evidence base for disclosures tied to risk, readiness, and resilience.
Portfolio Risk Prioritization: PRAs help identify which real estate assets face the greatest climate exposure, enabling smarter capital planning.
Regulatory Alignment: PRAs prepare organizations for requirements emerging under SEC climate risk rules, EU CSRD, and insurer underwriting expectations.
Reduced Losses & Faster Recovery: GRESB promotes resilience to protect asset value. PRAs provide the recommendations that directly reduce damage costs, downtime, and recovery periods.
Closing the Resilience Meets Sustainability Series
With Part 5, we conclude our Resilience Meets Sustainability series—demonstrating how Property Resiliency Assessments integrate with leading certifications and ESG frameworks, including LEED v5, BREEAM USA, Green Globes, WELL v2, and now GRESB.
Across each framework, the takeaway is consistent:
Resilience is no longer a parallel conversation to sustainability. It is foundational to it.
Organizations that embed structured climate risk identification, impact assessment, and adaptive planning into asset management processes are better positioned to:
Improve ESG disclosures
Strengthen investor confidence
Improve insurance positioning
Protect NOI and asset value
Align with evolving regulatory expectations
