Mehr.WERT.Pavillon - Added.VALUE.Pavilion

Federal Garden Show 2019 in Heilbronn, Germany

Students, researchers and professors of KIT Karlsruhe, together with the architects’ office 2hs, realize a circular pavilion from recycling materials at the Federal Garden Show 2019 in Heilbronn, which was ceremoniously opened on April 17th in the presence of German President Frank-Walter Steinmeier and State Minister Winfried Kretschmann.

The ‘Mehr.WERT.Pavillon’ is part of the so-called ‘Mehr.WERT.Garten’, a partner project of the Ministry of the Environment of Baden-Württemberg with the Entsorgungsbetriebe of the city of Heilbronn, and is located in an experimental area of the Federal Garden Show, the Inzwischenland. The inauguration of the pavilion and garden will take place in its own setting on 02 May 2019 with Environment Minister Franz Untersteller and Building Mayor Wilfried Hajek.

The pavilion and garden explore the question of how we and the generations after us can live well and how we can develop our economy positively while the natural resources of our planet become scarcer.

The pavilion was designed and built by students of the Karlsruhe Institute of Technology (KIT) in collaboration with the professorships for Sustainable Construction (Dirk E. Hebel, Felix Heisel and Karsten Schlesier), Structural Design (Matthias Pfeifer) and Building Technology (Rosemarie Wagner) as well as the office 2hs with Lisa Krämer and Simon Sommer. "It was important to us that sustainable architecture must be attractive and relevant. Especially within the construction sector a rethinking is possible, because we are able already today to build according to the principles of a circular economy– we just have to decide to do it," says Dirk E. Hebel, Professor for Sustainable Construction at KIT about the project.

The project demonstrates an innovative and sensible use of existing resources. All materials used in the project have already gone through at least one life cycle, either in the same or a different form. Materials are utilized in mono-material applications and all connections are designed for disassembly. "The project thus makes use of the existing urban mine on the one hand, but at the same time represents a material depot for future constructions after the end of the Federal Garden Show," explains Felix Heisel, project manager and partner at 2hs.

Conceptually, the project is based on four material layers: the load-bearing structure is made entirely of steel, most of which comes from a dismantled coal-fired power plant in North Rhine-Westphalia. The façade celebrates recycled glass materials from the glass container, such as MAGNA GLASKERAMIK® or foam glass. The floor areas in the garden and under the pavilion are covered with mineral building rubble, which comes directly or in processed form from recycling yards. The furniture and fixtures are made of recycled plastic materials.

Façade

The façade mainly shows two different products made of recycled and cullet glass. Magna Glaskeramik is made of 100 percent recycled glass and can be returned to the glass cycle after use. Transparent, green or brown bottle glass is fused into glass ceramic by a sintering process, which preserves the colour and shape of the broken glass and creates a special aesthetic.
