School Campus Stockbrünnele Böblingen
© Achim Birnbaum
The Stockbrünnele School Campus in Böblingen brings the previously separate Friedrich Schiller Secondary School and Theodor Heuss Secondary Modern School together in one building. The new four-stream school provides space for 750 students and is arranged alongside the existing buildings on the school site. At the same time, the city’s fresh-air corridor has been preserved—an important consideration in the urban planning concept. The main access to the schools is from Kremser Straße via separate entrances on the southeast façade. Each school has a spacious staircase connected to the courtyard, as well as a lift. Separate deliveries can be made via the lower-level workshop and art courtyard in the plinth level. All entrances and routes meet accessibility requirements.

Use Concept
The classrooms are arranged in an L-shaped configuration, creating a shared courtyard. With the student cafeteria directly adjoining it on the ground floor, the courtyard brings the two schools together in this area and provides a distinct place for exchange and communication among all students.

The educational spatial concept is based on the “Classroom Plus” model: Each pair of classrooms shares a differentiation room with visual connections between the spaces. Spacious corridors with open learning landscapes and flexible room zones complement the facilities.

In addition to 45 specialist rooms—including music rooms, teaching kitchens, and science areas—green loggias and the roof garden on the fourth floor provide space for communication, learning, and retreat. A school garden directly adjoining the teaching kitchens, as well as a multifunctional workshop courtyard between the new building and the existing cafeteria, further expand the educational opportunities outdoors.

Structural System
The school campus was built using a hybrid timber construction system. The plinth and ground floors, as well as the stair cores, are made of reinforced concrete, while the upper floors consist of prefabricated solid timber elements, including glued laminated timber floor slabs and cross-laminated timber walls. More than 2,900 m³ of timber were used. The high degree of prefabrication enabled a fast, dry construction process and significantly reduced the construction time.

Energy Concept and Sustainability
An energy concept was developed for the school campus that incorporates the latest standards for sustainable school construction. These include:
- Energy supply: District heating from the municipal network
- Ventilation: Central CO₂-controlled ventilation system with heat recovery
- Photovoltaics: A 190 kWp photovoltaic system with battery storage on the roof for on-site electricity generation
- Greenery: Green façades, roofs, loggias, and courtyard areas
- Water management: Rainwater collection in a cistern for toilet flushing and irrigation of the outdoor areas
- Building services: KNX-controlled LED lighting, comprehensive Wi-Fi coverage, and security and alarm systems meeting current standards
- Building materials: Use of sustainable, pollutant-free building materials
