Renaturing Cities and Restoring the Natural Water Cycle Through Green Infrastructure

  PIISA (Piloting Innovation Insurance Solutions for Adaptation) is a Horizon Europe project that brings together 12 organization’s from 5 European countries, and is co-developing climate resilient insurance portfolios. The project consists of several pilots, including one that aims to provide cost-benefit analyses of green roofs as a climate change adaptation option in the main pilot location in the Netherlands. The effectiveness of insurance solutions to stimulate the adoption of green roofs are being tested in this pilot as well, e.g. information provision and insurance premium discounts. Various enablers and barriers of the uptake of green roofs are being examined as well. Based on this work, public-private partnerships will be identified to investigate sustainable finance arrangements that stimulate investments in green roofs. Business models for the Europe insurance industry will also be developed for the upscaling of nature-based solutions for climate risk. Using expert interviews and workshops it is also being examined how the results for the Netherlands are transferable to other pilot regions, i.e. the Boreal and Mediterranean, using qualitative analysis.   Insurers, e.g. Interpolis, have been involved in the co-creation process for the research in the pilot. Furthermore, (potential) policy holders have been involved in the research process through economic experiments within which the (biodiversity, flood risk reduction, etc.) values of green roofs and the effectiveness of insurance solutions to stimulate the adoption of green roofs have been tested. Insurers, municipalities, water authorities and real estate institutions are being involved in the identification and development of public-private partnerships of sustainable finance arrangements for investments in green roofs. City policymakers and insurers are being interviewed and included in workshops in the Netherlands, and the Boreal and Mediterranean regions to examine how costs and benefits of green roofs differ, and whether additional barriers and enablers should be considered in the scaling up of green roofs as an insurance solution.

WGIN member iCARI kick-starts RE-URBANEX, a large-scale, EU-based public-private research project focused on long-term climate adaptation of built-up areas and building stock renewal. The current project evaluation exceeds €1.5 million and continues to grow, supported by a major PPP grant from STRABAG – one of Europe’s leading construction companies. Coordinated by iCARI and located on a 19,000 m² campus in Brno (Czech Republic), the project combines advanced data science, interdisciplinary collaboration, and high-frequency environmental monitoring. The aim is to test and verify real-world adaptation strategies: vegetation-based cooling, rainwater management, albedo optimization, indoor and outdoor air quality, and emission reduction. CzechGlobe, a top-tier climate change institute of the Czech Academy of Sciences, provides the project’s scientific backbone. Within the RE-URBANEX project, we explore a broad range of climate adaptation solutions and interactions, including green, blue, and grey infrastructure, the impact of urban heat islands, primary energy sources, BioSolar systems (combining greenery and photovoltaics), excess energy storage (including in the form of ice produced from harvested rainwater), indoor environmental quality, air quality, architectural and design strategies, and other innovative components. A dedicated part of the research also focuses on communicating results with an emphasis on practical application. RE-URBANEX is a living lab for cities, researchers, and companies ready to co-create tested, scalable solutions for climate resilience – backed by 15-minute interval measurements, running 7/24/365 over three years. The platform aims to expose and replace ineffective greenwashing with transparent and verifiable results. Timeline: October 2024 – December 2027 Key Deliverables: Climate-Sustainable Campus Plan Adaptation Handbook for Building Renewal Policy Recommendations for Municipalities & States Evidence-Based ESG Report for Public Institutions Guidelines for PPP Design and EU Funding Alignment Educational and Participatory Outputs Call for Technology Partners: If you develop innovative technologies for climate adaptation in urban environments and want to test them under real operational conditions – backed by detailed data and expert evaluation – RE-URBANEX offers a unique opportunity to become part of one of Europe’s most relevant adaptation projects.
