Project Overview

Building resilience and sustainability into Europe’s renovation transition

CLIMABUILD pioneers a replicable framework and inclusive digital ecosystem to accelerate deep renovation and climate resilience across Europe’s building stock. The project responds to urgent European priorities for a climate-neutral and adaptive built environment, integrating sustainability, resilience and stakeholder participation into practical pathways for building transformation.

At the core of CLIMABUILD is the novel Sustained Resilience method, which provides a new way to assess the ability of building stocks to balance short-term adaptive capacity, such as resilience to extreme weather events, with long-term sustainability objectives, including lifecycle carbon reduction and circularity.

Main Innovation

The Sustained Resilience method

The Sustained Resilience approach addresses current policy and assessment gaps by connecting resilience and sustainability across spatial and temporal domains. It introduces a tiered lifecycle model that enables the normalisation of both resilience and sustainability indicators, supporting more informed decision-making for renovation, adaptation and investment.

Climate resilience

Assessment of building stock performance under extreme weather and multi-hazard conditions.

Lifecycle sustainability

Integration of lifecycle carbon, circularity and long-term environmental performance.

Decision support

Practical outputs for planners, engineers, municipalities, citizens and investors.

Digital Ecosystem

AI-enhanced digital twins for participatory renovation planning

AI-enhanced digital twins

CLIMABUILD reconfigures digital twins as participatory co-creation engines, connecting technical building data with scenario-based planning and stakeholder engagement.

VR/AR tools

Immersive visualisation tools translate complex technical information into accessible insights, helping stakeholders understand renovation options and their impacts.

Tiered dashboards

User-friendly dashboards support citizens, planners, engineers and municipalities with outputs adapted to their specific decision-making needs.

Expected Impact

People-centred pathways for decarbonisation and resilience

01

Deep renovation

Supporting scalable renovation pathways across Europe’s building stock.

02

Low-carbon transition

Enabling lifecycle-based carbon reduction and circular construction strategies.

03

Multi-hazard resilience

Advancing threat-aware and threat-agnostic resilience for future climate conditions.

04

Policy-ready protocols

Providing benchmarks and protocols aligned with EU priorities and Built4People objectives.

Demonstration Strategy

Real-world validation across Europe

CLIMABUILD will be validated through a comprehensive real-world demonstration strategy across four countries, testing spatial, climatic and temporal service conditions. This validation will support representative benchmarks for safe, durable, inclusive and climate-resilient renovation.
