Besondere Merkmale
Allgemein
The new extension encloses an atrium in a U-shape on the upper floors, so that the classrooms on the inside of the building are also sufficiently well lit. Below the atrium on the first floor is the spacious assembly hall, which is additionally lit by skylights. An integrated stage makes the room multifunctional.
The listed old building was initially completely and extensively gutted and renovated with regard to its former material loads. The aim for all three parts of the building was to create a school complex with very good indoor air quality.
Both the actual hall area of the sports hall and the changing rooms are located in the underground area, so that the upper grandstand area for spectators could be implemented barrier-free.
Energetische Qualität und Konzept
The school campus is supplied by the district heating network of Dresdner Stadtwerke, which can demonstrate a very high proportion of renewable energy (>95%).
Thanks to the sustainable, all-round approach and project support, it was possible to achieve good interior quality in terms of thermal and acoustic comfort.
Weitere Besonderheiten
The two new buildings were constructed as a solid reinforced concrete structure. The facades are ventilated and clad with fiber cement and aluminum panels. Behind the pilaster strips of the school extension are narrow opening casements, which can be used for overnight cooling without posing a safety risk.
Monumental elements of the old building that required protection, such as the facade, windows, door portals, banisters and the former main entrance area, were carefully renovated or reconstructed in close consultation with the Office for the Preservation of Monuments.
