The livMatS Biomimetic Shell at the Freiburg Centre for Interactive Materials and Bioinspired Technologies is a pioneering research building which is investigating an integrative approach to planning and construction for sustainable architecture.

The requirement for the lighting concept was to create atmospheric lighting for the building that could also be used as technical ambient lighting.
An integrated lighting solution was implemented within the individual wooden cassettes. The linear LED profiles were mounted on the long inner sides of the cassette frames. As the building structure consists of cassettes of different sizes, the lighting had to be planned individually for each cassette. A warm light colour of 3,000°K was chosen to create a pleasant indirect room light.

Planning a sophisticated cabling concept was also crucial to ensure smooth communication between the 250 linear LED luminaires (350 m of LED strips in total). The control system used was DALI. A central control panel gives users the option of adjusting the light intensity individually.

The holistic lighting design with its precise technical specifications served to ensure the smooth implementation of the final man-machine processes. The luminaires were installed in close coordination between the robot input and the human body work. Thus, the initially simplified coding of the luminaires was translated into augmented reality and used as input for the manual installation of each individual luminaire in each cassette. The result is an absolutely staged success.
