The prefabricated panels used are timber-frame façade elements designed for a quick and efficient installation. Each panel is custom-sized to fit the building’s geometry. These panels integrate multiple layers, including thermal insulation, smart glazing windows, and ventilation units, enabling a high-performance envelope. The panels are engineered for quick on-site assembly, up to 180 m² per day, and are anchored to the existing structure after partial removal of the outer brick layer.

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.

Timber Prefabricated Multifunctional Façade
The façade elements are made of a solid wood exterior cladding based on slow-grown thermo-treated pine (heat treatment to improve timber stability). In the elements, both the OSB board on the inner surface and the outside wind barrier provide airtight layers within the building envelope.New energy efficient windows are integrated in the façade.
