03/10/2023 – Network Meeting: Presentation of the New Demonstrator Building

Presentation of the demonstrator building "livMatS Biomimetics Shell @ FIT”

digitize wood network meeting – Lecture event with site visit

In the seventh digitize wood network meeting we present the new research building "livMatS Biomimetics Shell @ FIT", which was jointly developed by the two clusters of excellence IntCDC and livMatS. The segmented wooden structure made of hollow cassettes is applied for the first time in a closed building and demonstrates the robotic assembly of a biomimetic shell in wooden construction. The building will soon open on the grounds of the University of Freiburg.

At this event, you will gain insights into the research and project management of this extraordinary building in three presentations and experience it live during a tour of the building. To the registration

About the Lectures

Integrative Design and Construction of an Interdisciplinary Research Project, Monika Göbel

The segmented wooden construction of hollow cassettes, designed by researchers from the IntCDC cluster of excellence at the University of Stuttgart, has now been applied for the first time in a closed building.

The envelope integrates acoustic elements in the hollow cassettes, adaptive, humidity- and heat-controlled shading flaps and an activated floor slab made of recycled concrete, which supplies the building with geothermal energy from underground collectors.

The basis of the cooperation in the implementation of the research building was that novel building constructions and building technologies were used that go beyond the recognized rules of technology.

Implementing these novel approaches to building research and transferring them into a building that can be used all year round was one of the challenges in realizing the "livMatS Biomimetic Shell @ FIT" cooperation project.

 

Robotic Manufacturing: Entirely Digitally Controlled Production of Integrative, High-Precision Building Components

The prefabricated hollow cassettes of the livMatS Biomimetic Shell required the integration of acoustic elements, lighting, insulation, facade connections and grip holes for automated assembly. The resulting high level of complexity in component geometries and -buildup was addressed with an entirely digitally controlled manufacturing process.

The heart of the fabrication was a transportable 7-axis robot platform, which allowed seamless integration of the modular fabrication setup in müllerbaustein HolzBauWerke GmbH's workshop within a few hours. The 12m-long robot unit enabled the simultaneous production of four components with lengths of up to 3.5 meters. A total of 127 individual hollow cassettes were assembled and glued from pre-formatted timber parts and subsequently milled, drilled and finally formatted with submillimeter accuracy by means of a large sawblade attached to the industrial robot arm. Manual assembly steps of special components such as lighting or insulation were supported by augmented reality and fully integrated into the digitally controlled production process. The accurate task distribution between multiple actors in one shared digital process chain allowed for a flexible and time-efficient production of complex, integrative components with very high precision requirements.

 

Semi-automated assembly of wooden buildings with large-scale manipulators, Anja Lauer

Within the context of the livMatS Biomimetic Shell @ FIT timber building, research was conducted on the automated assembly of building components on a construction site. For the first time, two assembly platform prototypes were developed and used on a real construction site. Prototype A picks up and places components automatically, while prototype B screws the wooden components into place using a specially developed and patented screw effector.

 

Solar Gate: Bio-inspired and Bio-based 4D printing - Intelligent Zero-Energy Shading, Tiffany Cheng

The aim of the Solar Gate is to regulate the indoor climate of the livMatS Biomimetic Shell by shielding its interior from high heat loads during the summer while allowing thermal energy to penetrate the building during the winter. Through the integrated development of hygroscopic cellulosic materials, bioinspired additive manufacturing, and design of 4D-printed shading elements in the context of environmental and site conditions, the facade system passively adapts to daily and seasonal weather cycles. As the first truly 4D-printed weather-responsive adaptive shading system, the Solar Gate represents a step towards a more sustainable, resource-efficient, and energy-autonomous solution for regulating comfort in our built environment.

About the Partners

The University of Stuttgart established the Cluster of Excellence on Integrative Computational Design and Construction for Architecture (IntCDC) in 2019. With an initial funding period of seven years, a Cluster of Excellence is the most significant and substantial grant awarded by the German Research Foundation (DFG). For the very first time, a Cluster of Excellence has been awarded to the field of Architecture. It will contribute to establishing an internationally visible research center. More information.

The vision of the Cluster of Excellence Living, Adaptive and Energy-autonomous Materials Systems (livMatS) is to combine the best of two worlds – nature and technology. livMatS develops life-like materials systems inspired by nature. The systems will adapt autonomously to their environment, harvest clean energy from it, and be insensitive to damage or recover from it. More information. More information.
