Innovative building envelopes with fibre-reinforced composite materials: state of art and possible integrations into ventilated façade systems

The building envelope plays an important role in meeting complex functional requirements and stringent green energy standards. The global energy demand is increasing and most of it is consumed in the building sector. The building envelope, which is responsible for the energy balance of the building, plays the most important role in achieving nearly Zero Energy Buildings (nZEB). In this study, innovative fibre-reinforced composite materials are integrated into certified building envelope system technologies. Variables associated with the production of fibre-reinforced composites are discussed, covering aspects of design, installation, and potential applications such as innovative ventilated façade and BIPV systems. Identification of tools, regulations, and test methods will be essential for evaluating design solutions in specific environments. Long-term performance includes maintenance and durability aspects. Based on a scientific approach and integrated design, the use of new technologies can significantly improve the overall behaviour of the building envelope. New strategies to scale up the many discoveries of green recycling through prevention, repair, and ideal reuse, contribute to cost-effective and sustainable practices of this material. This interdisciplinary approach addresses the multifaceted challenges of modern façade systems and paves the way for sustainable and energy-efficient building solutions.
