At its second location, the community elementary school will have eight day rooms, four themed rooms, four differentiation rooms, an open learning area and a canteen with a serving kitchen. There will also be team, administration, storage and technical rooms. A two-storey L-shaped building is planned. The classrooms are organized in class groups. Each class group contains two day rooms, a differentiation room and a theme room. On the first floor there are two class groups as well as the administration wing, a sanitary area, the canteen with serving kitchen and the building services rooms. On the upper floor, there are two further classrooms as well as smaller units of toilets and storage rooms. There is also an open learning area.
The new school building, which will be built by Bonn Municipal Building Management (SGB), will be equipped with passive house components for the building envelope and a ventilation system with a high degree of heat recovery and will at least meet the requirements for a KFW or ground floor efficiency building 40. The building is to be heated by a brine-to-water heat pump. The energy is taken from the earth at a depth of 100-150 meters ("geothermal energy"). A combination of green roof and photovoltaic system is planned for the flat roof. The respective substructures for the system will be pre-installed as part of the roof sealing and greening work. The solar cells will then be installed and the system operated by Stadtwerke Bonn (SWB).
As part of the construction project, the entire outdoor area will be planned as a school playground and equipped with age-appropriate play areas, play equipment and exercise facilities. A total of 116 bicycle and 84 pedal scooter parking spaces will also be created there. The partial planting of the Müldorfer Anger would promote the microclimate and provide shade for the school in summer. However, the planned planting requires further coordination before it can be implemented, as it is located outside the building site. Two infiltration trenches are planned on the outside of the school to allow the rainwater to seep away naturally.
The City of Bonn is expected to invest almost 25 million euros in the Adelheidis School annex. The total costs include a risk premium of 16.7 percent and a construction cost increase of six percent per year.
