IMPRESS will develop three different prefabricated panels for buildings: (i) a polyurethane based insulated panel with improved thermal performance and light radiation and (ii) a thin, lightweight pre-cast concrete sandwich panel, with optimum thermal and weathering resistance, both of which are suitable for overcladding; (iii) a lightweight pre-cast concrete sandwich panel incorporating Phase Change Materials (PCM) to adapt the thermo-physical properties of the building envelope and enable optimum passive heating and cooling benefits, suitable for recladding. Innovative nano/micro particle based coatings, suitable for 3D printing, will be also developed to achieve anti-corrosion resistance, high mechanical strength, improved solar reflectance, improved ageing resistance and anti-vandalism properties. To create the panels, an innovative manufacturing process will be created that includes Reconfigurable Moulding (RM) techniques, 3D laser scanning and 3D printed technology. In addition, 3D printed microstructured formworks will be developed as permanent external layer for the polyurethane panel to match the existing building aesthetics and provide solar radiation efficiency. The overall manufacturing process will (i) allow for mass production of panels, which take into account complex architectural and aesthetic issues, (ii) allow for faster production while lowering prefabrication costs and (iii) develop new controlled and cost effective solutions. IMPRESS will also develop a new Iterative Design Methodology, which will incorporate all stages of the Design-Construct-Install-Operate process. This will be integrated with a BIM cloud based database focussing on the interoperability between software tools required for the prefabricated process. Furthermore, new penalty based business models will be investigated. The final result will be demonstrated on two existing buildings where final as-built product performance will be validated against the initial design.

COREu will demonstrate key enabling technologies in a CCS value chain and support the development of three new CCS routes in Central-East Europe (CEE), helping accelerate CCS development . COREu will (a) provide the means for development of an open-access, trans-national network (infrastructure and logistic) to connect emitters with storage sites in Europe, by identifying multimodal transport requirements, and developing emitters’ clusters to create the demand and the investment rationale, (b) increase the knowledge of the CCS value chain across Europe through interconnected initiatives, sharing of experience, knowledge and data to create a common framework that encompasses all key aspects of CCS deployment: technological know-how, business models, consensus management, monitoring, reporting and validation, policy framework, transport and storage safety. COREU will contribute to 6.8Mt/year in CO2 reduction by 2035 and 36Mt/year by 2050, develop 8 innovations for Measurement Monitoring Verification, interoperability and Value Chain Monitoring, and improve the Internal Rate of Return of CO2 infrastructure investment by 6% through de-risking core technologies.

SIRCULAR intends to create digital tools, technological solutions and non-technical services for the decarbonisation of the built environment, as well as a ready-to-use methodology for assessing the circularity of a given building capable of evaluating the impact of the developed construction technologies in the demos. These features are intended to improve access to information on decarbonisation for end users who are not experts in these fields, as well as to provide professionals working in the construction sector with tools capable of easily evaluating and improving the circularity of this area. The SIRCULAR solutions will take a multidisciplinary approach, integrating technical, economic, and social approaches with a focus on social and policy innovation, delivering valuable information to policymakers and establishing a solid foundation for the promotion of developed decarbonisation methods. The project will also be distinguished by an overall people-centric approach that prioritizes the needs, ambitions, and well-being of individuals and communities as critical players in the decarbonization of the construction industry. SIRCULAR will prioritize active participation, inclusion, and ethical concerns to ensure that the project's achievements directly benefit society as a whole. The project will also make special efforts to engage the whole supply chain engaged in all phases of the building's life cycle, with the goal of increasing the circularity and sustainability of each of them. SIRCULAR plans to consider four national clusters to promote a circular and sustainable construction sector using a value chain approach. The clusters will focus on Estonia and Spain, followed by Germany and Greece. The clusters will involve construction companies, housing companies, universities, and local administrative entities, and will include buildings owned or occupied by fragile population groups, in line with the SIRCULAR just and affordable transition approach.

Historic buildings represents a considerable share of the European building stock (around 25%). They contribute to the identity and uniqueness of many cities and will only survive if they are maintained as a living space. To preserve a living built heritage, it is necessary to find energy renovation approaches and solutions compatible with conservation rules. This means that the historical and aesthetic value of these properties must be preserved while increasing the comfort of these living spaces, and minimizing their energy consumption and their environmental impact. The project aims to establish new knowledge for the development of sustainable and efficient solutions for historic buildings in order to bring cultural heritage to life and make it open, accessible, inclusive, resilient and low-emission. It is part of the pursuit of various projects involving members of the CALECHE network concerning, for example, bio-sourced renovation or "custom" PV integration. The studied solutions will cover all stages of operation (prevention, monitoring, maintenance) and renovation (setting up the operation, design, works).
