Priorities and funded actions

Some Horizon Europe budgets are structured in response to policy ambitions (“destinations”) and deployed through calls for proposals targeting more specific thematic/sector (“Topics”). Thus, your application must be linked to a topic of a call for proposals. 

Various categories of projects are eligible: 

  • Improved integration of buildings with energy carriers (e.g. electricity grid, district heating networks) and non-energy services (e.g. mobility).
  • Improved buildings flexibility for grid and network management.
  • Improved contribution of buildings to energy grid robustness with regard to dependencies to energy supplies.
  • Increase in renewable energy production and storage at building level.
  • Empowerment of end-users by having increased control over their buildings’ energy services and contracts (consumption, production, storage, flexibility).
  • Enhancement of the smart readiness of buildings as rated by the smart readiness indicator.

In addition, calls specify the categories of eligible beneficiaries: 

  • Collaborative projects, composed of a coordinator and several partners organisations (consortium) 
  • Single-beneficiary projects, involving a single organization 
  • Individual scholarships, open to natural persons in their own name with their home institution 



  • HORIZON-CLC5-2024-D4-01-01: Low disruptive renovation processes using integration of prefabricated solutions for energy-efficient buildings
  • HORIZON-CLC5-2024-D4-01-02: Smart grid-ready buildings
  • HORIZON-CLC5-2024-D4-01-03: Alternative heating systems for efficient, flexible and electrified heat generation in industry
  • Total budget of the call: 103 million euro 
  • Amount per topic: 
    • HORIZON-CL5-2024-D4-01-01: 10 million euro
    • HORIZON-CL5-2024-D4-01-02: 10 million euro
    • HORIZON-CL5-2024-D4-01-03: 16 million euro 

This grant is a lump sum grant.
