Amelie Weber // Application of cycle-compatible building materials based on the example of a kindergarten



In Germany, around 30% of greenhouse gases are caused by the construction sector. It also generates 55% of our waste and consumes 50% of the raw materials. In concrete terms, this means that buildings produced around 120 million tons of CO2 in 2018 and around 240 million tons of waste in 2019. In addition, raw materials consumption is about 701 million tons. Therefore, the construction sector contributes more than any other industry to polluting our environment and consuming far more than we are entitled to. As such, the sector also bears responsibility for improving the relationship between the natural and built environment, reducing resource consumption, and acting in a sustainable, generationally responsible man-ner. Sustainability in architecture is often confused with optimizing current processes and making them more environmentally friendly. However, new, circular processes are needed, as well as a rethinking of what a building can also mean, for example a material database. The re-thinking and the shaping of a new everyday life should start with the smallest of us, the children. My design for the new building of the Kindergarten Schagenstraße is composed of five two-story, gabled houses, each of which could function as an independent building. On the first floor is the spacious entrance area with the cloakroom, where parents say goodbye to their children and pick them up again. Furthermore, the group rooms for the children over the age of three are located here, as well as a movement room and the shared kitchen. The upper floor houses the groups for the children under the age of three and the staff area. Currently, there is a shortage of childcare staff in eastern Germany and a shortage of child-care places in western Germany. Planning for kindergarten places is complicated by demo-graphic and socioeconomic developments. Since 2016, the German birth rate has been de-clining again and factors such as migration are difficult to predict. It may be that in 15 years there will be a surplus of childcare places, but it may also be that new places will still be needed. That's why it was important to me to plan a kindergarten building that functions as a house construction kit, so that after it has been used as a kindergarten, a large number of other building types are possible with these materials and house modules.
