INPERSO is a holistic deep renovation programme addressing the building’s entire lifecycle and combining industrialisation and personalisation. The project will deliver inclusive, affordable, efficient, and sustainable renovation, adaptable to various climate zones and building typologies, but focused on residential and heritage buildings. Aiming to deliver a near-market solution, INPERSO is comprised of five highly exploitable, integrated results (IRs) plus an underlying, human-centric methodology for low-carbon renovation. New technological components leveraging the advantages of prefabrication, pre-integration and robotic 3D printing will drastically reduce the time (>50%) and costs (>25%) of construction, and increase resource efficiency, productivity and quality, coupled with waste reduction (>40%). The project highlights the advantages of digital solutions, by integrating scan-to-BIM, AI, AR and ML into the established RE Suite platform, creating a solid foundation for harmonising information flows and addressing the fragmentation challenges of the sector. These resources will also be used to optimise building energy performance and indoor environment quality, as well as improving the energy footprint of the renovation process, in addition to improving working conditions and safety. INPERSO will be demonstrated in Spain, Netherlands, and Greece, forming energy communities and promoting sustainable energy use. Ambitious upscaling and replication plans, supported by green financing and six business models, will be implemented to generate local and EU-wide impacts. The Consortium consists of 8 research organisations, 8 SMEs, 2 large enterprises and 3 NPOs, privately investing €4.7M in the project.

The DigiFab consortium will develop a renovation process consisting of: 1) Digital process chain with detailed assessment and co-creation methodology to cover the entire renovation workflow; 2) Choice of adaptable prefabricated modules with passive and active technologies to achieve near zero energy building (NZEB) levels and reduced environmental impact; 3) Assessment and monitoring software with building information modelling (BIM) to automate the process. Estimated installation time is 2 days per unit of 200m2 surface, with 30% less cost than conventional renovation. Our solution transforms the renovation process by digitizing it from design brief to finalization. The approach, not widely adopted in the sector, offers significant cost and time reduction by accurately collecting and centralizing data at all stages, minimizing uncertainties that cause delays and increase costs. Co-creation with occupants gathers expectations and best renovation times. Building data is collected with accurate methods, transformed into a high-quality digital twin that automates energy and structural analysis, leading to design optimization with the best technology combinations according to project inputs. Results from the analysis are used directly to manufacture the prefabricated modules using modern methods of construction (MMC) and “just in time” (JIT). The modules use novel lightweight concrete mixes with recycled materials, bio-based materials, active envelope heating technologies, energy generation and management including ventilation. Installation follows specific site conditions, monitored through procedures such as laser scanning. A worksite solution is used to manage and monitor levels of construction demolition waste, and noise. At the end of the commissioning process, energy performance documentation is provided. Three demonstration sites in Spain, Austria and Greece with diverse building typologies will showcase how the DigiFab solution benefits stakeholders.
