The image shows an aerial view of a modern building complex surrounded by streets, car parks and green spaces. In the centre of the image is a large, curved building with a roof surface that is completely covered with solar panels. The solar panels are arranged in several parallel rows and utilise the entire roof surface. Below the curved building is a wide road that winds around a circular green area with a tree in the centre. This road separates the main building from another large, rectangular building, which is located in the lower left-hand section of the picture. This building has a flat roof and is surrounded by grey paved areas and other green spaces. At the top of the picture is an extensive park with various footpaths running through it. There are numerous trees and shrubs in the park, creating a natural and green environment. At the top right of the picture is a long, straight road that separates the park area from the rest of the grounds. Another road is visible on the left-hand side of the picture, which also has a cycle path and footpath to the left and right of the road. Yellow markings show an entrance to the building complex which is blocked by a barrier.

The picture shows a light-flooded part of an office space. Two men can be seen sitting at a desk directly in the foreground, stretching from left to right in the lower third of the picture. The man sitting on the left has short, dark brown and curly hair, a brown-red beard, wears round glasses with black frames and a black shirt. The man to his right has almost black short hair, a brownish beard and is wearing a black T-shirt. Both men are looking at the two monitors on the desk in front of them.

To the right of the monitors is a telephone and next to it, on the right-hand edge, two letter trays are stacked. In the background you can see a wall consisting of large windows that stretches from the first left third of the picture to the right edge. In addition, the ceiling, which can be seen in the upper part of the picture, also consists of the same large windows. On the right-hand side of the picture, a dark brown, approximately waist-high room divider can be seen, which bends to the right once. Six plants can be seen on the room divider and behind it. To the left of the picture, directly next to the man on the left, is a wall consisting entirely of green plants.
