Objective
"FLEXI-BUILD addresses a primary barrier to Europe’s clean energy transition: the fragmentation of smart building solutions across technologies and building types. While advanced energy management systems are available, their integration remains project-specific, limiting scalability and system flexibility. FLEXI-BUILD aims to demonstrate and scientifically validate how interoperable, human-centric smart buildings can deliver measurable energy efficiency and demand-side flexibility under real-life conditions. FLEXI-BUILD validates a common, vendor-agnostic interoperability architecture that upgrades existing HEMS, BEMS, and EMS without replacing them. By separating communication, semantics, and service layers, the project enables the reuse of optimization services across heterogeneous typologies. This architecture is deployed in four large-scale pilots: residential (Greece), office/living lab (Norway), public school (Belgium), and industrial cold storage (Serbia). Beyond technical integration, FLEXI-BUILD shifts focus from isolated flexibility events to the systematic assessment of ""flexibility readiness"" under comfort, environmental, and process constraints. It combines data-driven forecasting with human-in-the-loop decision support and explainable interfaces. Social sciences and humanities expertise is embedded throughout the project to ensure trust and alignment with user needs. Using harmonized technical and societal KPIs, FLEXI-BUILD generates comparable evidence on energy performance, effort reduction, and user acceptance. Through a structured exploitation strategy and a Multi-Actor Forum, the project translates results into market-ready business models and policy insights, supporting the large-scale uptake of smart buildings as active components of the European energy system."

Net EU financial contribution. The sum of money that the participant receives, deducted by the EU contribution to its linked third party. It considers the distribution of the EU financial contribution between direct beneficiaries of the project and other types of participants, like third-party participants.
