Smarter buildings as part of the energy system for increased efficiency and flexibility – Societal Readiness Pilot -
Call text (as on F&T portal)
View on F&T portalExpected Outcome:
Project results are expected to contribute to all of the following expected outcomes:
- Measurable reduction in buildings’ energy demand together with a reduced gap between their as-designed and as-built energy performance;
- Measurable increase in the number of building typologies with smart grid connected renewable energy sources (RES) and energy storage together with increased flexibility in grid/network management and operations;
- Measurable enhancement of the smart readiness of buildings as rated by the Smart Readiness Indicator and/or other relevant building rating systems;
- Improved responsiveness by the relevant stakeholders to the needs and concerns of users from a diversity of social groups, including vulnerable and disadvantaged ones, involved in or potentially affected by the smart buildings, thereby increasing the potential for beneficial societal uptake and building trust in outcomes.
Scope:
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.
Proposals are expected to address all of the following:
- Develop solutions that enhance the smartness of buildings by using and facilitating the upgrade of existing Building (Energy) Management Systems (BMS/BEMS) and/or other technical equipment;
- Ensure that the proposed solutions are user-friendly and provide the expected indoor environmental quality, as well as user satisfaction and occupant comfort;
- Demonstrate the proposed solutions in at least three pilots. These pilots should collectively cover at least three different climatic zones, three different building types (residential, tertiary etc.), and three different technical building systems;
- Develop a methodology to measure the achieved energy demand reduction, increased flexibility in the grid, and enhanced interoperability, compared to current best practices;
- Investigate the cost-effectiveness and replicability of the proposed solutions.
This topic is a Societal-Readiness pilot:
- Proposals should follow the instructions applying to the Societal readiness pilot, as described in the introduction of the Horizon Europe Main Work Programme 2025 for Climate, Energy and Mobility. They entail the use of an interdisciplinary approach to deepening consideration and responsiveness of research and innovation activities to societal needs and concerns.
- This topic requires effective contribution of the relevant SSH expertise, including the involvement of SSH experts in the consortium, to meaningfully support Societal Readiness. Specifically, SSH expertise is expected to facilitate the socio-technological interface and enable the design of project objectives with Societal Readiness related activities.

Activities are expected to achieve TRL 6-8 by the end of the project – see General Annex B. Activities may start at any TRL.

[1] Proposals with the same score were ranked according to the priority order procedure set out in the call conditions (for HE, in the General Annexes to the Work Programme or specific arrangements in the specific call/topic conditions).
To determine the ranking for ‘Innovation actions’, the score for ‘Impact’ is given a weight of 1.5.
[2] According to the specific condition of HORIZON-CL5-2026-02-D3-01, to ensure a balanced portfolio coverage, grants are awarded to proposals not only in order of ranking but at least also to one proposal that is the highest ranked within the area of liquid advanced biofuels and at least also to one proposal that is the highest ranked within the area of liquid renewable fuels of non-biological origin, provided that proposals attain all thresholds (and subject to available budget).
According to the specific condition of HORIZON-CL5-2026-02-D3-05, to ensure a balanced portfolio coverage, grants are awarded to proposals not only in order of ranking but at least also to one proposal that is the highest ranked within the area of concentrated solar power (CSP) and at least also to one proposal that is the highest ranked within the area of solar thermal heat and/or cold, provided that proposals attain all thresholds (and subject to available budget). Therefore, additional proposals are retained for funding to fulfil this condition.
According to the specific condition of HORIZON-CL5-2026-02-D3-08, to ensure a balanced portfolio coverage, grants are awarded to applications not only in order of ranking, but priority will be given to high-ranking proposals that ensure, collectively, the best coverage of the different European sea basins (Atlantic Ocean, Baltic Sea, Black Sea, North Sea and Mediterranean Sea), provided that the proposals attain all thresholds. Therefore, additional proposals are retained for funding to fulfil this condition.
According to the specific condition of HORIZON-CL5-2026-02-D3-14, to ensure a balanced portfolio coverage, grants are awarded to applications not only in order of ranking but at least also to one project that is the highest ranked within area 1., 2. or 3., provided that the applications attain all thresholds. Therefore, additional proposals are retained for funding to fulfil this condition.
According to the specific condition of HORIZON-CL5-2026-02-D3-24, to ensure a balanced portfolio coverage of both (i) point-source capture and (ii) direct air capture technologies, grants are awarded to not only in order of ranking but at least also to one proposal that is the highest ranked within each area, provided they attain all thresholds (and subject to available budget).
Summary of observer report:
The process was professionally organized and executed with rigor. It was fair, impartial, expertise-driven, and transparently documented at every step. Consensus Reports, the definitive outputs of the evaluation, consistently met high quality standards, closely aligned with the published and communicated guidance, and complied with all applicable rules. Panels were composed to ensure balanced expertise, and newly introduced Vice-Chairs facilitated discussions that were structured, respectful, and evidence-based. Divergent assessments were addressed through focused, criterion-by-criterion debate, and rationales were clearly recorded to ensure traceability.
Robust safeguards supported integrity and consistency. Conflict-of-interest declarations were systematically collected and enforced. Calibration briefings promoted a common understanding of scoring scales and evaluation criteria, enabling consistent judgments across proposals and panels. Quality control mechanisms, including cross-checks, effectively harmonized outcomes without compromising the independence of assessments. Confidentiality was maintained throughout. Access controls in the SEP system and teleconferencing platforms were appropriate, data handling was secure, and sensitive information was treated with due care.
Operationally, the evaluation benefited from clear timelines, timely support to evaluators, and a reliable digital infrastructure. The documentation was complete and accessible, and the SEP system provided full transparency over inputs and decisions. Overall, the exercise adhered to its core principle, namely impartiality, fairness, and confidentiality throughout. The resulting evaluation summary reports and ranking list are consistent, well-reasoned, and aligned with the guiding documents.
We recently informed the applicants about the evaluation results for their proposals.
