Testing Activities for Technological and Normative Validation of Bio-Based Components in Façade System Modules

This research explores the development and validation activities of a bio-based façade system within the Basajaun H2020 project, focusing on enhancing the utilization of bio-based components within building envelopes to replace conventional solutions with eco-friendly alternatives. This paper reports the methodologies employed to detect requirements and outline the testing protocols undertaken to validate the façade system design devised within the project, focusing on the original façade components as the biocomposite profile. Vision and opaque façade modules are prototyped and tested following curtain wall standards for performance (EN 13830:2015) and acoustic assessments (EN ISO 717-1:2020) to showcase the efficacy of the developed solution. The conducted tests demonstrate the feasibility of integrating bio-based components as alternatives to conventional materials into building envelopes, aligning with project expectations and prevailing standards for curtain wall façade solutions. Notably, the designed façade system meets technical conditions and research objectives. Nevertheless, the paper underscores the need for further refinements to facilitate solution industrialization and explore broader market applicability focusing on the biocomposite profile.
