Phase out fossil fuel in energy intensive industries through the efficient integration of renewable energy sources

Optimal combination of low embodied carbon construction products, technical building systems and circularity principles for climate neutral buildings (Built4People Partnership)

Opened

Code: 38261 | Identifier Code: HORIZON-CL5-2026-02-D4-05 | Programme name: 2939 | Sub-program: Climate, Energy and Mobility (Cluster 5)(2021-2027) | Start submission calls: 16/09/2025 | End submission calls: 17/02/2026

Buildings result in greenhouse gas emissions over their whole life cycle (operational and embodied emissions). Buildings can also contribute to long-term carbon removals by storing carbon in construction products.

Construction and renovation works must also meet a variety of inter-related requirements such as structural and fire safety, acoustics, and a healthy and comfortable indoor environment.

Although much research has focused on developing materials and products with reduced whole life carbon emissions, the life cycle impacts of buildings depend on a complex interaction between individual products, components and technical building systems, spatial distribution, usage during their lifetime, and other design choices.

There is therefore a need to deliver buildings and renovation works with minimal life cycle impacts, in particular global warming potential, based on circularity principles, also accommodating future building use-change through design for flexibility, and using innovative combinations of products and systems that result in optimal building-level performance.

Innovative approaches for the deployment of Positive Energy Districts

Opened

Code: 38257 | Identifier Code: HORIZON-CL5-2026-02-D4-04 | Programme name: 2939 | Sub-program: Climate, Energy and Mobility (Cluster 5)(2021-2027) | Start submission calls: 16/09/2025 | End submission calls: 17/02/2026

Recent projects have demonstrated the feasibility of PEDs, but there is a need to further demonstrate climate-neutral impact, while developing and demonstrating innovative approaches and solutions for overcoming technical, business, social and organisational constraints in several domains.

Such domains include, for example, climate mitigation, integration of renewable energy sources and energy storage in buildings, grid connections, accommodation of distributed energy generation and storage at district level, permitting, data privacy and security and the application of new technologies such as artificial intelligence.

Presently, these constraints, which inhibit the demonstration of complete and qualified PEDs, require the cooperation of key professionals from the public and private sector, such as municipal and regional authorities and those from the energy and construction sectors, in complex implementation processes.

Innovative pathways for low carbon and climate resilient building stock and built environment (Built4People Partnership)

Opened

Code: 38252 | Identifier Code: HORIZON-CL5-2026-02-D4-03 | Programme name: 2939 | Sub-program: Climate, Energy and Mobility (Cluster 5)(2021-2027) | Start submission calls: 16/09/2025 | End submission calls: 17/02/2026

EU and associated countries continue to develop innovative building solutions that support the decarbonisation and climate resilience of buildings and the built environment, addressing energy performance, circularity, sustainability, resource efficiency, climate resilience, safety, durability and adaptability of the building stock, and whole life carbon emissions.

A key challenge remains the accelerated uptake of such solutions in building and renovation projects.

Building value chain actors – such as housing association, municipal and regional authorities, or policy makers – require planning methods and procedures that embed the uptake of innovative building solutions and define pathways for the decarbonisation and climate resilience of the building stock and the built environment under their responsibility.

Smarter buildings as part of the energy system for increased efficiency and flexibility – Societal Readiness Pilot

Opened

Code: 38249 | Identifier Code: HORIZON-CL5-2026-02-D4-02 | Programme name: 2939 | Sub-program: Climate, Energy and Mobility (Cluster 5)(2021-2027) | Start submission calls: 16/09/2025 | End submission calls: 17/02/2026

The construction sector and the building subsector remain among the least digitised.

Smart buildings can contribute to reducing energy demand, curbing operational CO2 emissions, integrating RES and enhancing grid flexibility through optimised energy usage.

At the same time, it is essential that smart buildings are flexible and adaptive to changing needs and usage patterns and are user-friendly to encourage widespread adoption of these technologies by grid operators, construction professionals, building facility managers and users.

Furthermore, to ensure the societal benefits of the smart building technologies there is a need for increased user knowledge, acceptance and satisfaction.

• Develop open-source tools for forecasting, prediction and advanced data analysis using AI tools and in-depth data analysis for customers and prosumers for autonomous optimisation of consumption, production, storage, smart devices (appliances), and electric vehicle (EV) both at household and energy community levels;
• Extend DSO SCADA and substation systems for autonomous control of grid assets and seamlessly integrate these systems with home and building energy management systems for direct and fast control and data acquisition to implement local (distribution) grid services (constrain alleviation, grid reconfiguration, restoration of supply, maintenance, and enhancement of energy quality), real-time assessment and monetisation of the use of grid resources;
• Integrate the three elements above as a basis to establish a platform for cooperation between individual customers or prosumers, entire energy communities, wide area aggregators, and DSOs to provide, acquire, and settle energy system-oriented services (system-wide balancing, support of frequency regulation). The cooperation platform should be based on a plug-and-play integration of the energy community eco-system components (hardware and software), using and extending relevant communication standards and data models. The integration mechanism should be embedded within the core systems used by customers/prosumers, DSO (and TSO), aggregators and market operators, fully aligned with SGAM;

• Ensure the follow-up and implementation of EU policy measures, including by conducting quality assessments and introducing national community energy targets;
• Foster institutional allies at local and regional levels;
• Provide access to and capacities for using digital planning tools;
• Identify the barriers for network operators (e.g. legal, economic, regulatory etc.) who want to introduce smart consumption options for their customers.

The challenge is the development and demonstration of cost-effective wave energy converters that can survive in a harsh and unpredictable ocean or sea environment through demand-driven pre-commercial procurement (PCP). The challenge is open to proposals seeking to steer wave energy development in an effective way at a European level and to bring these technologies to the market.

The operation of wave energy prototypes in real sea conditions is a critical step to establish confidence in the devices and to facilitate the large-scale roll-out of this renewable technology. Pre-commercial procurement has been shown to be an effective tool to de-risk such activities.
