Version of this project
For decades, Friedrich-Ludwig-Jahn-Sportpark (Jahn Sportpark for short) has offered various sports clubs, schools and universities the opportunity for training, competition and sporting activities in the heart of Berlin. Recreational athletes also benefit from the access and the extensive opportunities offered.
The sports facility has a far above-average occupancy rate compared to other nearby sports facilities due to a wide range of sporting and cultural uses. However since 1 January 2021, the stadium could only been usable for operations to a limited extent due to the poor structural condition. (Source).
Integrated planning team
In an interdisciplinary cooperation, a competence centre for inclusive sports (KisS) has been realised in mass timber by our partners MAX Holzbau in cooperation with Stadt.Haus.Mensch. (Architecture, Cradle To Cradle), Hüls Ingenieure (Structural Engineering), Bohne Ingenieure (TGA) and Ahner Landschaftsarchitektur and the Senatsverwaltung für Inneres und Sport of Berlin using a prefabricated mass timber Sylva™ kit of parts by Stora Enso.
Rib Roofs
The ribbed ceilings consist of 114 m2 of CLT/GLT Ribbed panels manufactured by Stora Enso (CLT RP O 140 L5s VI GL24h VI 2x 140x320) and preassembled by MAX Holzbau at their location Breydin, Germany. The application of CLT and GLT Rib Panels for the ceiling enabled uninterrupted spans. The CLT and glulam Rib Panels, designed by MAX Holzbau and manufactured by Stora Enso, reduced the material use by nearly 50% compared to standard Sylva™ CLT Roofs, maximizing floor-to-ceiling heights and resulting in a lighter overall structure.
Sylva™ Services
This project leveraged the use of Stora Enso's Sylva™ Services and preinstalled lifting devices in their mill's factory-controlled conditions, so when the elements arrive on-site, they were ready to install safely, immediately.
Carbon footprint
The CLT only generated 3 tonnes of greenhouse gases (CO₂e) to manufacture and less than one tonne of CO₂e to transport. Compared to the 40 tonnes of carbon dioxide that the trees removed while they were growing and will store in for the school this is a small fraction. Choosing CLT instead of non-renewables avoided 60 tonnes of greenhouse gases. Source: Stora Enso Carbon Calculator based on third-party verified EPDs.
