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 silhouette of a woman holding documents against the backdrop of modern skyscrapers. The perspective of the picture is from the bottom up, making the buildings look monumental and impressive. The woman is in the foreground of the picture, turned slightly to the left. Her profile is clearly visible and she appears to be looking intently at her documents. She is wearing a jacket and has tied her hair up in a bun. Several glass buildings can be seen in the background, taking up most of the picture. The building on the left of the picture is only partially visible, with a large round pillar extending upwards. The centre building is the most dominant and extends almost to the top of the picture. It has a glass and steel façade and reflects the sky. Another building can be seen on the right of the picture, which also extends upwards and forms a right angle to the centre building. The glass façades of the buildings give the picture a modern and urban feel. The sky is clear and slightly bluish, indicating a sunny or at least clear day.

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 row of narrow but tall terraced houses. The terraced houses have alternating grey and white façades. On the left you can see a house with a white façade and on the far right a house with a grey façade. They are also always built at different heights, so that there are never two houses of the same height next to each other. All the houses have a large square window front in the upper half, consisting of 30 small square windows. The window front of the fourth house from the right is the only one covered by a blind. All of the houses have four individual windows under the fronts, with two on the left and two on the right below each other. Above the houses you can see the almost completely cloudless blue sky. In the foreground in front of the houses you can see a lawn with many bushes and a total of four trees, three of which can be seen on the left at the edge of the picture and one tree on the right.

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.

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.

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.

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.
