Official call identifier: HORIZON-NEB-2026-01-REGEN-02
Objective of the call
This call aims to extend the service life of existing buildings and reduce their life cycle environmental impacts by improving maintenance and repair approaches.
It supports the development and uptake of predictive maintenance for existing buildings, helping to reduce reactive interventions and improve the sustainability and performance of the built environment, in line with recent policy developments such as the recast Energy Performance of Buildings Directive (EPBD).
Scope of activities
Proposals must address all of the following:
- Develop at least one prospective life cycle assessment (LCA)-based decision-support tool for predictive maintenance and repair of existing buildings
- Develop at least one package of maintenance and repair measures to extend the estimated service life of existing buildings, which:
- Integrates circularity principles, is environmentally sustainable and financially feasible over the remaining life cycle of the building(s)
- Involves inhabitants, users and owners in the design and implementation
- Complies with European and national regulatory requirements
- Minimises disruption for inhabitants/users (including noise and duration of works)
- Demonstrate both the decision-support tool(s) and the package(s) of measures on three buildings located in three different Member States and/or Associated Countries, including:
- At least one heritage building
- At least one social and affordable housing project
- Explore the potential for wide-scale application of predictive maintenance in existing buildings, identify barriers to implementation, and propose solutions to overcome them
Projects are expected to follow a participatory and transdisciplinary approach through the integration of different actors and disciplines.
The effective contribution of Social Sciences and Humanities (SSH) is required, including the involvement of SSH experts and institutions.
Proposals must allocate at least 0.8% of the budget to engage with the Horizon Europe-funded “New European Bauhaus hub for results and impact” to share results and contribute to impact assessment.
