The German pavilion is one of the few that very generously lets in natural light into the interior. We defined and fine-tuned the design for the upper lighting in terms of number of fixtures, distribution and the transmittance of the glass in multiple simulations. The passage of light through clear glass and the breakthrough of direct sunbeams are desired and intentionally made possible. We used films to show how the cones of lights will move through the interior space. Only the center stage is shaded from the spots of sunlight.

No other pavilion at the EXPO 2020 was given such an intense natural lighting design. It was a statement about the sustainable use of natural light.
