The INFINITE project began by focusing on the “demand-side”, identifying key stakeholder categories and their needs and requirements, and aligning them with the features of industrialised all-in-one envelope kits and supporting digital tools development.
The development of INFINITE technologies has been completed, following phases of ideation, technical design, mock-up creation, manufacturing, and testing. Five multifunctional timber-based façade and roof kits—covering greenery, energy and fresh air (E&FA) distribution, smart windows, BIPV, and BIST—are now ready for use in three real-life demo renovations. This progress was supported by collaboration with INFINITE consultants on materials, smart connectors, LCA/LCC, and design for assembly/disassembly, leading to a unified set of multidisciplinary Key Performance Indicators to assess the kits.
Moreover, the main functionalities of the aBMS have been internally released after the development of the user stories answering the main needs of users (mainly inhabitants, facility managers, designers and owners). Finally, the INFINITE nZEB vision has been defined, while mapping the different national regulations to facilitate the design of high-performance norm-compliant buildings
Demonstration is central to INFINITE. The three demo buildings in Italy, Slovenia, and France followed a shared process to ensure renovations are affordable, effective, and efficient. The executive design phase was completed in mid-2024, and most technologies for the Italian and Slovenian demos were produced and shipped by year-end. Installation of the prefabricated façade and roof elements took place between late 2024 and May 2025, with monitoring systems now collecting building performance data.
The French demo faced delays due to the ATEX approval process for the BIPV kit and strict regulatory requirements.The methodology to assess the Virtual Demo Cases(VDC)using the INFINITE concept has been defined. Preliminary geometric modeling has been completed, and the BIM-P, Energy & Comfort, and LCC plug-ins have been tested across the six VDCs. Results confirm the feasibility of the approach, though slightly higher costs compared to traditional deep retrofits were observed. The analysis will be updated with real data from the IT and SLO demo cases.The communication and dissemination of INFINITE approach and results have been running constantly. An audience around the project has been created thanks to the project website, the use of social media, the periodic and regular newsletter, and the participation in conferences and events. Several training and dissemination activities have been organised to highlight the value of industrialised retrofitting, including workshops, webinars, a two-day Offsite Academy in Milan in 2024, and a site visit to the Italian demo building in 2025. INFINITE has also been presented at conferences, fairs, and industry events.
