Parametric Design: Durable & Recyclable Facade

The bioplastics facade mock‐up was created within the framework of Research Project Bioplastic Facade, aproject supported by EFRE (Europäischer Fonds für Regionale Entwicklung/ European Fund for RegionalDevelopment). It demonstrates one of the possible architectonic and constructional applications of thebioplastic materials developed in the course of this project. The blueprint is based on a triangular net made upof mesh elements of varying sizes.

Research Project Bioplastic Facade: 
ITKE can look back on numerous years of experience in both teaching and researching the computer basedplanning, simulation, and production of cladding for buildings with complex geometries. Currently, materialsmade from petroleum‐based plastic, glass, or metal are used to encase such structures. Thermoformablesheets of bioplastics will constitute a resource‐efficient alternative in the future as they combine the highmalleability and recyclability of plastics with the environmental benefits of materials consisting primarily ofrenewable resources. 
Collaborating materials scientists, architects, product designers, manufacturing technicians, and environmentalexperts were able to develop a new material for facade cladding which is thermoformable and made primarily (>90%) from renewable resources. Developed by project partner TECNARO within the framework of theresearch project, ARBOBLEND®, a special type of bioplastic granules, can be extruded into sheets which arefurther processable as needed: They can be drilled, printed, laminated, laser cut, CNC‐milled, or thermoformedto achieve different surface qualities and structures and various moulded components can be produced. 
The semi‐finished products serve as cladding for flat or free‐formed interior and exterior walls. The materialcan be recycled and meets the high durability and inflammability standards for building materials. The goal ofthe project was to develop a maximally sustainable yet durable building material while keeping petroleumbasedcomponents and additives to a minimum.The ecological audit was completed by project partner ISWA (Institute for water engineering, water quality,and waste management). Furthermore, the materials’s resistance to microbial degradation was determined. 
nnovative Character of the Research Project: 
This research project marks the first occasion for development of bioplastic sheets that are made primarily ofrenewable resources, can be freely formed, and are furthermore designed for application in the building sectorand specifically for building exteriors. At the beginning of this project, such a product was not available on themarket. The conception of this material as flame‐retardant sheet material also aims at applications for buildinginteriors (spek DESIGN). 
With this new development, we can therefore soon offer a product that addresses two trends: 
‐ the increasing demand for resource‐efficient and sustainable building materials 
‐ the increasing development of buildings featuring double‐curved geometries and planar facade componentswith 3D effects (relief)
