The picture shows a few skyscrapers that are seen from below. Two of them are clearly shown, the others are build behind them or can’t be seen from this point of view. On the skyscraper on the left side are just plain windows, but the skyscraper on the right side has greenery on every floor and is beeing illuminated by the sun.

The picture shows an impressive view from below of the top of a modern tower block. On the right-hand side of the picture, the building rises steeply into the sky, its façade consisting of vertical, shiny silvery stripes and windows that reflect the surrounding environment. Lush green trees can be seen on the left and in the lower part of the picture, their dense leaves dominating the image. The sun's rays break through the leaves, creating a warm, golden light that is reflected in the tower block. The sky is partly cloudy, with blue and white colour tones that add depth to the image.

The picture shows a modern office building on a sunny day. The building is in the centre of the picture and takes up most of the frame. It has a glass and metal façade that reflects the daylight. The structure of the building consists of several rectangular glass windows separated by vertical and horizontal metal struts. The metal struts are in different colours, giving the façade a lively and modern look. In the foreground, at the bottom right of the picture, you can see a tree whose green leaves are brightly illuminated by the sunlight. The leaves partially cover the bottom right corner of the building. The sky is clear and blue with only a few small clouds in the top left of the picture. The sun's rays create lens effects that can be seen as bright, circular reflections in the picture. In the upper left area of the picture, at the edge of the building, a few plants can be seen on a roof garden, bringing a touch of nature into the otherwise urban picture.

The picture was taken diagonally upwards towards the ceiling of the office space. As a result, you can see the dark brown ceiling with white ceiling elements and silver pipes stretching across the entire ceiling in the background. In the lower left part of the background, you can see several office desks and glass partitions. You can also see a man sitting with his back to the viewer. On the right, in the background, you can see more glass partitions, more office desks and chairs and a white wall with two large bright windows. The entire background is blurry, as the photo focuses on the man sitting at a white office desk with a light grey laptop in the foreground, from which the photo was taken. The man is wearing a light blue shirt with a dark blue jumper over it and black square glasses. His hair and beard are greying, and he is smiling as he talks to a customer about their Energy-Management-Minute-Review provided by ista.

The picture shows an electric car that is being charged. In the foreground is the car's charging socket, into which a charging cable is plugged. The cable is connected to an ista EV charging station, which is outside the picture. In the background, slightly out of focus, is a man in a light-coloured suit talking on the phone. He has a relaxed posture and is leaning slightly against the car. The scene probably takes place in an urban environment or in a company car park, which is indicated by the modern buildings in the background. The image conveys an atmosphere of modern technology and environmentally friendly mobility.

The picture shows a young woman looking through a window. She has long blonde hair and is wearing a dark blue, polka-dotted top. The woman is smiling and holding a tablet in both hands which is showing the Energy Audit Reporting from ista, her gaze directed slightly to the right. Green plants and a blurred light source can be seen in the background, giving the picture a warm and inviting atmosphere. The light source is located approximately in the centre of the background. The left background area shows a vertical black line, which is probably part of the window frame. The woman is standing relatively close to the window so that her reflection is partially visible in the glass. The foreground of the image is in focus while the background remains blurred, which draws the viewer's attention to the woman's smiling face and her tablet.
