Façade System Based on Biocomposites
A new façade system based on renewable raw materials is reported to increase the energy efficiency in building construction. The energy required for production is up to 50% less than that for conventional building materials.
As part of the "BioBuild" research project, the world's first self-supporting façade system based on biocomposites was presented. The panels used in the system have a height of 4 m, a width of 2.3 m and contain a glass window element. The façade system was developed primarily for commercial properties. It consists of two outer shells of a flax fabric and natural resins as well as an internal insulating layer. The elements are delivered to the construction site as finished components. All parts of the system can be separated from one another easily and either recycled or reused at the end of their lifecycle. The energy required for production is up to 50% less than that for conventional building materials without additional costs.
The biocomposite façade system was developed as part of the BioBuild project by Arup Deutschland GmbH, Berlin, and GXN Innovation, Copenhagen. The objective of the project is to use innovative building materials based on natural, fast-growing renewable resources. The regenerative materials are intended to replace conventional building materials such as aluminum, steel, tile and concrete. Such materials are based on natural flax, hemp, and jute fibers as well as natural resins obtained as by-products during agricultural processing of corn and sugar cane. They can be processed to yield lightweight, durable and strong products that improve the sustainability of building systems. The façade system was honored at this year's JEC Innovation Award Europe in the "Construction" category.
