D3.6 Lessons learned from testing usage in Lyon, France

PIISA stands for “Piloting Innovative Insurance Solutions for Adaptation” and it's a 3-year Research and Innovation Action funded under the Horizon Europe program within the call “HORIZON-MISS-2022-CLIMA-01”. The partnership brings together 12 organisations from 5 European countries, and will co-develop climate resilient insurance portfolios, as well as develop solutions for sharing losses and climate risk data. The Clay Shrink Swell Building Damage Assessor (CSSBDA, as referred to in the Grant Agreement and previous deliverables as the PIISA climate adaptation dashboard) is an online website designed to educate homeowners about the financial risks associated with inadequate insurance cover for property damage caused by clay shrink swell (CSS) events. This document analyses lessons learnt from pilot testing the CSSBDA in the City of Lyon during the period from March to August 2025 which will be integrated into our planning and work activities for replicating the CSSBDA at French national level.
