Entry Description

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 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 controls and cabling concept was also crucial to ensure smooth communication between the 250 linear LED luminaires. 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. Thus, the initially simplified coding of the luminaires was translated into augmented reality and used as input for the human manual installation of each individual luminaire in each cassette. The result is an absolutely staged success.
Sustainability Approach

The building orientation and the daylight strategy comprehends a weather responsive shading system that allows solar gains in winter and therefore sufficient natural lighting throughout the year. Although expansive, a resourceful and minimalist artificial lighting scheme has been proposed, which includes energy efficient LED luminaires and a control system that helps reducing the building carbon footprint yet complying with required functional lighting norms. The indirect atmospheric ambience created, supports also the well-being and comfort of the users in the space, which creates a healthier future work environment.
