Average Annual Loss: Annual Average Loss expressed as a percentage of the replacement costs.

Asset Count: Number of assets in the polygon (see Hazard).

Breakdown Hazard Chart: Risk Fraction per year per hazard (see Breakdown).

Hazard Risk (avg): Average annual aggregated risk per hazard.

Opacity: How much you can see through the polygon colour to the base map (see Area View).

Overview Chart: Risk Cost over time for the asset (see Overview).

Hazards and their impacts

Forest Fire: Fire events in grassland or forest, which include result in exposure to temperatures consistent with direct flame exposure and damaging radiant heat.

Coastal Inundation: Seawater flooding caused by high sea events.

Heatwave: Extreme heat temperatures exceeding thresholds such as operational scope, causing failure.

Extreme Wind: High speed wind gusts that exceed the building standard of a structure.

Riverine flooding: Water Inundation of the civil height or floor height of an assets due to surface flows and increased river heights as a result of high precipitation events. Also called fluvial flooding.

Soil movement: Reactive clays cause soil subsistence during low precipitation which can cause cracking and movement of foundations.

Other Terminology

Archetype: In order to understand how climate change interacts with infrastructure, archetypes are used to classify similar groups of assets & how they will be impacted. An archetype forms a structure of an asset and defines how the asset is exposed to hazards. An archetype is a representative class that allows the use of general or repeatable information and avoids having to uniquely specify all the characteristics of individual assets.

Key Performance Indicator (KPI): Financial or non-financial impacts are referred to in terms of other Key Performance Indicators (KPI’s), such as unplanned water supply outages or a failure to meet water quality standards; each of these KPI’s will have its own associated metrics.

Heat Stress: A KPI used to measure the impact of Heatwave events on people.

Risk Cost - Also referred to as Average Annual Loss (AAL): Risk Cost is the sum of the Annual Average Losses (AAL) across all of the assets. These losses are due to the direct cost of damage only, and do not include consequential costs (e.g. loss of income). Annual Average Losses are typically the basis of an insurance premium, to which transaction fees and other adjustments will be added.

Risk Fraction: Total Risk Cost per year divided by the total asset value.
