This demo case consists of the innovative renovation of two twin residential buildings. One building is being upgraded with advanced INFINITE prefabricated facades, while the other uses traditional methods. This comparison aims to evaluate life cycle costs, life cycle assessments, installation time, user feedback, consumption, and performance. The prefabricated approach includes high-performance facade panels, a new lightweight wooden roof with integrated BIPV tiles, and prefabricated balconies with embedded ventilation units. The renovation also incorporates glass-glass colored BIPV panels, BIST cladding, and smart glazing windows. Extensive monitoring pre- and post-renovation provide detailed data on the efficiency and effectiveness of the prefabricated solutions.

Kasava Building Retrofit
Czech Republic
Multi-family social housing building divided in two blocks due to terrain topography, with 15 apartments total (5 per floor across 3 residential levels plus basement garage).The main façade is east oriented, with unique entrance, while the west façade features open common corridors.The building underwent deep renovation with timber prefabricated multifunctional façade (PMF) on 1st and 2nd floors of east façade, integrating PV panels, ventilation systems, and new balconies.The U-value of the existing façade amounted to 0.64 W/m²K before renovation.After renovation, significant gains were observed:Ground Floor: 0.37 W/m²K (with conventional ETICS)1st-2nd Floor: 0.16 W/m²K (with PMF panels - Prefabricated + Existing wall)

Coma del Forn
Spain
The retrofit project involves a small multi-family building (2 storeys) and 8 apartments, built in 1975. The envelope, façade and roof, has been entirely retrofitted.The building’s façade has been renovated using prefabricated modules with integrated high-performance technologies. The approach minimized disruption for residents by enabling work to be completed within a very tight timeframe. The renovation was carried out as part of the European project H2020 4RinEU.
