Project term

March 2017 – September 2019

The new laboratory and office building of Sartorius Stedim Cellca is oriented from the base to the roof to the requirements of the biotech company and the quality standards of the globally operating life science group Sartorius. With its functional assignment of premises to processes and workflows, the Cell Line Development Center has created the constructional prerequisites for meeting the growing demand for stable cell cultures for the biopharmaceutical industry optimally.

The basis for the complex was our preliminary concept study, in which we developed a economic building that will optimally accommodate the future processes of the company. An essential component of the study was the analysis of existing processes and the development of process optimizations. The result: a modern new building, which consists of a one-storey plinth with underground car park underneath, including delivery area, and a three-storey block on top with a striking glass facade.

In the new laboratory area, glass system partitions enable open, bright workplaces and flexible laboratories. At the same time they seal off the sensitive production facilities of cell cultures hermetically and offer highest product safety and quality. A glass corridor along the laboratories opens up to visitors – mostly current or future clients – an insight into the ultra-modern development rooms.

In the office area, an open-space variant was implemented, which on the one hand offers a high degree of flexibility and opportunities for exchange between employees and on the other hand many retreats and think tanks.

The glass facade is a special eye-catcher, which was developed from intensive consultation with the client and an internal design competition in our company: On a total area of more than 3,200 square meters, 675 glass panes were installed in a structural glazing facade construction. Each of the up to 650 kilogram heavy elements is a unique design. Like pieces of a puzzle, together they form the image of a large cloud. The effect was created in a novel double digital printing process with white cell round dots in different sizes, which were applied to the entire glass facade.

In the area of the laboratory windows further effects are visible: It is possible to look outside, but not inside the building. Furthermore, it is possible to dispense with external sun protection, as the points shade the glass surface by fifty percent, which reduces the amount of solar radiation entering the building and thus the heating of the laboratory wing behind it.

DGNB Gold zertifiziert

Für das Gebäude wurde ein besonders energieeffizienter Betrieb angestrebt. Der KfW55-Standard konnte für dieses Gebäude realisiert werden. Ein sehr guter Dämmstandard der Gebäudehülle, hocheffiziente Wärmerückgewinnung und niedrigen Druckverlusten im Bereich der mechanischen Belüftung führen zusammen mit der Eigenstromerzeugung über eine PV-Aufdachanlage zu einem sehr niedrigen Energieeinsatz. Die hieraus resultierenden niedrigen Lebenszykluskosten und die herausragende Ökobilanz ermöglichten eine DGNB Gold Zertifizierung des Gebäudes.
