A major challenge is coming for the real estate sector in Europe: improving the resilience of buildings. The Green Building Observatory is launching its R4RE – Resilience for Real Estate – platform to make building resilience analyses accessible in a few clicks. This will help guide future investments, thanks to a risk analysis compatible with the adaptation criterion of the European Taxonomy.
The R4RE resilience platform has been made available for free to all since 30 June, following the launch conference by the ESREI team. The main information about the platform can be found here.
This platform will allow you, in a few clicks, to have information on the risks to which your building is exposed from the address and some technical questions about your building. This tool can be used for buildings located anywhere in Europe.
Risk maps and indicators
Using databases made available by scientists, the OID has been able to carry out data processing and analysis work with regarding issues of the real estate sector to produce viewable maps and risk indicators for buildings.
Sector players with login credentials will be able to connect to a professional space to upload data for a group of buildings and retrieve risk indicators for the entire group.
The R4RE resilience analysis will be composed of several parts, including a component on climate risks (Bat-ADAPT) and a component on biodiversity (BIODI-Bat). At this stage, only the Bat-ADAPT analysis, and therefore the climate indicators, have been put online.
Climate change: 3 scenarios to 2100
This climate analysis is prospective and is based on IPCC data for the following 3 scenarios:
- An ambitious scenario, which aims at a temperature increase of only 1.5°C;
- An intermediate scenario, which limits the temperature increase to 2°C ;
- A Business-as-Usual scenario, which corresponds to a temperature increase of 4°C or more.
The time horizons observed are near (2030), medium (2050) and long term (2090).
The risk analysis will focus on 8 hazards: heat, drought, precipitation and flooding, coastal dynamics, forest fires, storms and high winds, land movements, and extreme colds. These 8 hazards were identified following an analysis of the classification of hazards in the annexes of the European Taxonomy regulation. On 30 June, only the analysis on heat has been made available. Analyses for the other hazards will be made available in regular updates between 2022 and 2023.
For each of the scenarios and time horizons, the building address allows to know the exposure of the building to the climatic risk. According to building profiles, determined from the technical questions, the vulnerability of the building is analysed. The crossing of exposure and vulnerability results in an overall assessment indicator of the climate risk to the building.
Thank you to all our partners!
The Green Building Observatory would like to thank the experts who answered all our technical questions and all the scientific and technical partners: Météo France, the Centre National de Recherches Météorologiques (CNRM), CEREMA, the Institut Pierre Simon Laplace (IPSL), the Bureau de Recherches Géologiques et Minières (BRGM), the Observatoire National des Effets du Réchauffement Climatique (ONERC), the Association des Directeurs Immobiliers (ADI), the Global Alliance for Building and Construction (GlobalABC) and the Mission Risques Naturels (MRN).
Our thanks also go to our financial and/or institutional partners: the sponsors of the ESREI programme for the Bat-ADAPT component, ADEME, the Plan Bâtiment Durable, the Ministry of Ecological Transition, the City of Paris and the Paris Climate Agency.
