Future-proofing historical buildings for the clean energy transition

Deadline: 20 April 2023

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

  • Reduction of energy demand by at least 60%, preserving historical and cultural heritage values;
  • Reduction of on-site construction waste;
  • Improved lifetime renovation cost effectiveness compared to conventional renovation;
  • Significant reduction in maintenance costs;
  • Increased effectiveness and potential for replicability of the proposed solutions.


Around a quarter of the existing building stock in Europe was built prior to the middle of the last century. A significant number of these have a poor energy performance and are costly to renovate. Many recently developed renovation approaches are not adapted to the specific requirements of historical buildings.

Proposals are expected to address all of the following:

  • Deliver standardised renovation approaches and solutions for the deep renovation of historical buildings;
  • Target building types constructed prior to 1945 that have restrictions regarding changes of their envelope;
  • Solutions that reduce energy demand in a cost-effective way;
  • Improve the comfort of the occupants and lower the maintenance cost for building owners;
  • Explore both internal and external insulation solutions;
  • Standardised renovation approaches and solutions that are directly replicable for other buildings of the same building type
