Design and production technology of natural fibre reinforced polymers not only aims to offer products with a lower environmental impact than conventional glass fibre composites but also caters for designers’ needs for the fabrication of lightweight free-formed architectural components. To combine both characteristics, the forming process itself, on...
Reevaluating the materials that shape our built environment holds significant importance for sustainable construction. This research introduces newly developed natural fibre pultruded profiles, composed of flax fibres and bio-resin, customised for specific properties and targeted applications.

The selection of materials in the construction industry plays a pivotal role in advancing sustainability goals. Traditional materials derived from natural resources face inherent constraints linked to geographic limitation, growth time, and geometric inconsistency and therefore recent attention has shifted towards developing novel bio-based materia...
This article aims at addressing the future challenges in Sustainability and Information Technology (IT) by reversing the order of the conventional prioritization of social objectives and technology, and placing the aim first and the means second. In engineering and technology, historically, there has been greater focus on first developing the techn...
As the use of Natural Fiber Reinforced Polymers (NFRPs) become increasingly popular in the built environment, steps in established workflows, including molding and transportation, continue to impose constraints on what is possible in the material’s fabrication process. This research builds on previous studies of moldless fiber composites using tail...
In a resource-constrained world, raising awareness about the development of eco-friendly alternative materials is critical for ensuring a more sustainable future. Mycelium-based composites (MBC) and their diverse applications are gaining popularity as regenerative, biodegradable, and lightweight alternatives. This research aims to broaden the desig...
The building industry needs to innovate towards a more sustainable future and can do so through a combination of more renewable material choices and less wasteful fabrication processes. To address these issues, a hybrid material and fabrication system was developed using laminated timber veneer and natural fibre-reinforced composites (NFRPs), two m...
Voluntary certification schemes are a necessary driver for sustainable transition in the building industry. In Denmark, the primary scheme is DGNB with its holistic understanding of sustainability, rewarding environmental, social, and economic sustainability equally. The DGNB scheme, however, does not currently have a manual contextualized for smal...
There is an essential need for a change in the way we build our physical environment. To prevent our ecosystems from collapsing, raising awareness of already available bio-based materials is vital. Mycelium, a living fungal organism, has the potential to replace conventional materials, having the ability to act as a binding agent of various natural...
Biomimicry is an interdisciplinary approach to study and transfer principles or mechanisms from nature to solve design challenges, frequently differentiated from other design disciplines by its particular focus on and promise of sustainability. However, in the biomimicry and biologically inspired design literature, there are varying interpretations...
Design of the built environment is becoming gradually more important to maintain the quality of life and biodiversity. Integration of architecture and biology has great potential since biotechnology and biology’s developments lead to understanding how nature works. Interdisciplinary studies, which are inspired by nature and related to the fields of...
This contribution presents the prerequisites in the construction process of a bio-based experimental pavilion. A first challenge, is to define tolerances and implicitly measurement tolerances for these materials. After defining them, the focus is set on what can be achieved if geometric quality control is only conducted during the assembly process....
This research demonstrates an integrative computational design and fabrication workflow for the production of surface-active fibre composites, which uses natural fibres, revitalises a traditional craft, and avoids the use of costly molds. Fibre-reinforced polymers (FRPs) are highly tunable building materials, which gain efficiency from fabrication...
Angesichts von Klimawandel und Ressourcenknappheit tritt eine Materialgruppe als

enormes Potential, dessen Erschließung gerade erst beginnt.
The application of non-renewable building materials including concrete and metals in construction industries have caused a major impact on the environment including the destruction of more than 45% of the global resources, the consumption of 35% of energy and nearly 40% of energy-related emissions (UN Secretary-General’s High-Level Panel on Global...
Under normal conditions, the cross-sections of reinforced concrete in classic skeleton
construction systems are often only partially loaded. This contributes to non-sustainable construction solutions due to an excess of material use. Novel cross-disciplinary workflows linking architects, engineers, material scientists and manufacturers could o�er a...
Fiber Reinforced Polymers (FRPs) are increasingly popular building materials, mainly because of their high strength to weight ratio. Despite these beneficial properties, these composites are often fabricated in standardized mass production. This research aims to eliminate costly molds in order to simplify the fabrication and allow for a higher degr...
Building envelopes separate the confined interior world engineered for human comfort and indoor activity from the exterior world with its uncontainable climatic forces and man-made immission. In the future, active, sustainable and lightweight building skins are needed to serve as an adaptive interface to govern the building-physical interactions be...
