OSCAR’s CIRA Physical Risk Tool – A Demo of New Financial Impact Functionality

Location:

Hybrid – virtual plus Midtown New York in-person

Jose Manuel Carmona, Alpha-Klima and OSCAR Data Scientist, will demonstrate the CIRA tool’s new advanced asset financial impact analysis. The tool can calculate several key metrics of the financial impact on a physical asset (commercial building, power plant, etc.) of multiple types of climate hazards across multiple scenarios and timeframes due to loss and impairment.
