  • Action type: RIA (HORIZON-CL5-2022-D4-02-03)
  • Opening date: 6 September 2022
  • Closing time: 24 January 2023 17:00 (Europe/Brussels)
  • Budget per project: € 5 000 000 of total € 20 000 000
  • Estimated number of projects funded: 4
  • Official website


Expected Outcome:

Project results are expected to contribute to all of the following expected outcomes:

  • Increased availability and enhanced overall performance, including with regard to cost-effectiveness, of solutions applicable to the reliable and respectful historical renovation of heritage buildings, preserving their architectural and cultural identity.
  • Demonstrated potential of sustainable, energy and resource-efficient historical renovation of heritage buildings.
  • Better protection of the value and long-term inclusiveness, accessibility and usability of cultural heritage sites.
  • More cost-effective and less disruptive modernisation and preservation of the heritage built environment.
  • Enhanced prevention and monitoring of the heritage built environment.
  • More important role of the cultural heritage in deployment, showcasing and replication of solutions for a sustainable built environment.


The proposal should:

  • Deliver technically and socially innovative, sustainable, energy and resource-efficient solutions for the cost-effective improvement and preservation of cultural heritage built environment along all relevant aspects: inclusiveness, accessibility, resilience, environmental and energy performance.
  • Ensure the proposed solutions cover all relevant aspects of the heritage built environment’s life cycle: design, renovation works, operation, monitoring and management, and maintenance.
  • Ensure the proposed solutions allow to maintain the heritage value (e.g. artistic, historic, archaeological, social and scientific) of targeted sites, while improving access and comfort of users and visitors, and reducing maintenance and operational costs.
  • Ensure, where relevant, that the proposed solutions rely on (adapted) historical or traditional construction techniques and materials for sustainable restoration.
  • Ensure the proposed solutions include natural low maintenance as well as advanced renovation techniques for high quality design and construction, including new digital technologies, while preserving the cultural value of the targeted sites.
  • Ensure the proposed solutions contribute to facilitate the integration renewable energy sources while respecting the aesthetic and cultural identity of the targeted buildings.
  • Ensure the proposed solutions contribute to the cost-effective improvement of the energy performance, also reducing the cost of the interventions compared to traditional methods.
  • Ensure the involvement of relevant stakeholder groups (e.g. civil society organisations, associations, cultural heritage stakeholders such as cultural heritage protection bodies) and citizens’ acceptance thanks to co-creation processes and socially innovative ideas.
  • Deliver and demonstrate decision-support tools for low-disruptive, optimal renovation of heritage built environment to enhance sustainability.
  • Clustering and cooperation with other relevant projects is strongly encouraged; e.g. with the Horizon Europe Partnership on ‘Driving urban transitions’.
  • This topic requires the effective contribution of SSH disciplines and the involvement of SSH experts, institutions as well as the inclusion of relevant SSH expertise, in order to produce meaningful and significant effects enhancing the societal impact of the related research activities.
  • This topic should consider social innovation as driver of social change, new social practices, social ownership and/or market uptake.

This topic implements the co-programmed European Partnership on ‘People-centric, Sustainable Built Environment’ (Built4People).

Specific Topic Conditions:

Activities are expected to achieve TRL 5 by the end of the project – see General Annex B.

Cross-cutting Priorities:

Social Innovation
Socio-economic science and humanities
