Built for engineers. Designed for decision-makers.
Class 3 was born out of Arup, the global engineering consultancy behind some of the world's most complex built environment projects. Our founders have designed buildings to withstand disasters.
We built Iris to scale complex climate risk assessments without sacrificing consultant-grade rigor. It is trusted by engineers who have a professional obligation to get it right, every time.
Today, that same methodology helps owners, operators, investors, and their advisors screen portfolios, prioritize investments, and reduce risk with confidence.

Asked Questions
How is Iris different from other climate risk tools?
Iris uses a component-based engineering methodology that analyzes actual building systems and their physical failure modes. Most tools assign scores based on coarse hazard grids and generic building assumptions. Our bottom-up approach produces traceable, defensible consequences outputs that you can trust: repair costs, downtime, and revenue loss tied to specific hazard intensities and specific building components.

What hazards and geographies do you cover?
Flood: riverine, stormwater, and coastal + sea-level rise
Wind: cyclonic, tornadic, straight-line wind
Geophysical: earthquake shaking
Climatological: wildfire, extreme heat, extreme cold, drought, snow, ice storm
Datasets and maps from the world's best climate modelers, all in one place.
Global coverage. Enhanced flood resolution: up to 10m in select regions, 30m globally.
Probabilistic and return period-based intensity metrics that are best damage indicators.
Most hazards include climate change projections following IPCC standards across present-day, mid-century, and end-of-century timeframes, using multiple climate models and emission pathways (SSP scenarios).

What types of assets can you assess?
Individual buildings and portfolios across all major property types: we have pre-assembled hundreds of archetypes across offices, data centers, hospitals, industrial facilities, logistics warehouses, retail, residential, and specialized structures, using our component-based approach.
You can model individual buildings component by component directly in Iris, down to the bolts.
Generate new archetypes, specific to your use case, using the same methodology.

How does Iris model risk?
Iris breaks risk into the three components behind every catastrophe model: hazard, vulnerability, and exposure.
Hazard: how likely an event is and at what intensity. Iris quantifies exposure at the building footprint from probabilistic provider data, with intensities expressed as return-period values (e.g., flood depth at the 100-year event).
Vulnerability: how damageable the building is. Iris models it at the component level (structural, mechanical and electrical, and building envelope), with fragility functions relating hazard intensity to the probability of damage at each severity level.
Exposure: what the building and its components are worth and how they are used. Occupancy type, replacement cost, component inventory, and the number and sensitivity of occupants all feed the model.
Together they produce a probabilistic distribution of loss and downtime for the asset.

Do you support regulatory climate disclosures?
Yes. Iris outputs are compatible with TCFD, EU Taxonomy (CSRD), SFDR, SB261, and other major disclosure frameworks. We provide multiple climate scenarios including mid-century and end-of-century projections, with standardized exports formatted for compliance reporting.
Report by fund, business group, geography, rentable area, and much more.

What kind of reports and data do I get?
PDF reports with maps and executive summaries, CSV/Excel exports for portfolio analysis, and API access for system integration.
All outputs include risk ratings and detailed impact metrics: repair costs and downtime, with options to include revenue loss, inventory loss, life safety, heat misery index, and heat-induced hospitalizations. Results are delivered with probabilistic ranges (10th, 50th, 90th percentiles).

How does your pricing structure work?
We use a consumption-based token system where different assessment types consume different amounts of tokens based on complexity (see the Class taxonomy under Methodologies) and data requirements.
Pricing includes base license fees plus token consumption, with volume discounts available.
Contact us for a customized quote based on your specific requirements.

How quickly can I get results, and do I need special expertise?
Class 0 assessments return results instantly. Just input an address or coordinates.
Class 1 assessments take minutes with basic building information like occupancy type and height category.
Class 2 assessments benefit from more building insights, including vintage, structural type, finish floor elevation, and more, typically validated through review of property reports, drawings, and street views.
Class 3 assessments involve full engineering-grade analysis with site-specific data collection, typically scoped as a project engagement with an advisory partner, with results delivered on platform.
