Professur Nachhaltiges Bauen / Sustainable Construction

The international competition “beyond bauhaus – prototyping the future”, sought ground-breaking design ideas and concepts that address a socially relevant topic and provide creative answers to the pressing questions of our time. Almost 1500 projects coming from 50 countries applied for an award. The 20 award winners convinced the international jury with their ideas and concepts. The spectrum of entries reflects the challenges of our time: it ranges from food cultivation on the water to individually dosed medicine and new technologies for urban development to sustainable building materials. The Professorship of Sustainable Construction Dirk E. Hebel together with Philippe Block and Juney Lee from ETH Zürich (Mycotree) and Werner Sobek and Bernd Köhler from the Werner Sobek Group Stuttgart (UMAR) won two of the awards.

Renewable building material for the city of tomorrow

Steel and concrete—these are the first materials that come to mind when one thinks about building. But our resources are finite, which is why construction must break new ground. Scientists at the Karlsruhe Institute of Technology (KIT) and the Swiss Federal Institute of Technology in Zurich (ETH) with its research outpost FCL in Singapore are leading the way by researching alternatives to conventional building materials. A result of years of research is “MycoTree”, a self-supporting structure made of fungal mycelium and bamboo. Design Team: KIT: Dirk E.

Closed material cycles in civil engineering

The world’s natural resources are limited, which is why we need to rethink how we use and reuse everything — away from linear material-consumption and towards an economy of recycling. The Urban Mining and Recycling (UMAR) housing and research unit of the Swiss research institute Empa at “NEST” is demonstrating what this paradigm shift in the construction industry might look like. Architects Werner Sobek, Dirk E. Hebel and Felix Heisel have come up with a building concept that uses entirely separable resources, either reusable or compostable: mortar-free, folding walls made of recycled demolition debris, bathroom cladding made of recycled plastic chopping-boards, or mushroom mycelium as compostable wall-insulation. UMAR is thus not only a material laboratory but also a material depot. It is also proof that responsible use of natural resources and modern architecture can go hand in hand.

“The illustration shows an excerpt from the Mehr.WERT.Pavillon, which was recently opened on the Heilbronn BUGA site, where all the materials used have already undergone at least one life cycle – either in the same or modified form. “Anders Bauen” does not always have to mean that no new materials are used, but intelligent, restrained and gentle handling of materials and ressources should always be the goal. And so, for this issue, which continues our series of congresses and booklets on Sufficiency in building culture, we also tracked down projects (new buildings and conversions) that live up to this claim. Housing models, working environments, office buildings as well as cultural and community centers, where the clients and architects asked themselves before the planning process began: how much space do we really need and how can we optimally use and design it? Which functions can be organized jointly, which ones individually? And what can be obtained from the found, what is added meaningfully new? Good usable and used architecture, which also provides food for thought – like the experimental pavilion.” db

Glück auf am Theodorschacht! The winners of the second Urban Mining Student Award have been announced: The first prize in this student competition goes to Torben Ewaldt and Sofie Fettig from the Karlsruhe Institute of Technology (KIT). They were able to convince the jury with their resource-saving draft of a conference and learning center for circular economy. The planning task of this Germany-wide, open student competition was to design a conference and learning center for circular economy and resource conservation at the Theodorschacht in Ibbenbüren. The mine was closed at the end of last year as one of the last two coal mines in Germany. The task was to strengthen the place with its historical significance and to enrich it with forward-looking use.

From the total of 34 submitted design proposals, the jury awarded four prizes and five recognitions. The first prize went to Torben Ewaldt & Sofie Fettig from the Karlsruhe Institute of Technology; Jan Martin Müller of the Bergische Universität Wuppertal was awarded the second prize, and Lisa-Maria Behringer & Ruth Mathilda Meigen as well as Jasmin Amann & Marieteres Medynska were delighted to receive two third prizes each.

At the KIT’s annual celebration, Professor Alexander Wanner, Vice President for Teaching and Academic Affairs, honored lecturers at KIT. The award winner at the Faculty of Architecture is Prof. Dirk E. Hebel with his team of the Professorship of Sustainable Construction.

With faculty teaching awards, the KIT board praises research- and application-oriented teaching modules as well as lectures and teaching teams at the KIT faculties, which are characterized by new forms of teaching and learning, interdisciplinarity and high relevance of the imparted expertise. Prof. Dirk E. Hebel and his team are also nominated by KIT for the Baden-Württemberg state teaching award 2019.

The existing lack of affordable urban housing also concerns Karlsruhe. Socially acceptable densification is therefore one of the great challenges of these days.

Architecture students in their 5th semester at KIT therefore devoted themselves to the question of how good and forward-oriented living can be achieved in the future. The question was how living can be thought BETTER, so that OTHER typological models lead to a rethinking of architectural approaches in urban space, while consuming LESS land, as all designs were asked to be top-up additions to an existing structure in central Karlsruhe.

Ten of those design proposals are shown in the exhibition in Architekturschaufenster Karlsruhe, Waldstraße 8, 76133 Karlsruhe. The exhibition is a collaboration of KIT Chair of sustainable Building, Volkswohnung Karsruhe and Architekturschaufenster.

The opening takes place on Tuesday, May 21st, 19:00 h

Wie sich vorhandene Rohstoffe nachhaltig in das Bauwesen einbinden lassen, zeigt ein Pavillon, der als Gemeinschaftsprojekt von Studierenden des KIT und den Fachgebieten Nachhaltiges Bauen (Professor Dirk E. Hebel), Tragkonstruktion (Professor Matthias Pfeifer) und Bautechnologie (Professorin Rosemarie Wagner) entstanden ist. Der Pavillon ist Teil des Mehr.WERT.Gartens, eines gemeinsamen Projektes des baden-württembergischen Umweltministeriums und der Entsorgungsbetriebe der Stadt Heilbronn, und steht – selbst vollständig aus wiederverwendeten und -verwerteten Materialien entworfen und realisiert – symbolisch für die Notwendigkeit, recycelte Ressourcen nicht länger als Müll zu betrachten, sondern deren Potenzial zu nutzen. Den Initiatoren geht es darum, einen Paradigmenwechsel, wie wir mit unseren Ressourcen wirtschaften, voranzutreiben. Das aktuell vorherrschende, sogenannte lineare Wirtschaftsmodell der Massenproduktion und des Massenkonsums, bzw. der Wegwerfwirtschaft, muss sich ändern, hin zu einer Kreislaufwirtschaft aus geschlossenen und reinen Stoffkreisläufen. Der Mehr.WERT.Pavilion ist das Herzstück einer Ausstellung über lokale und globale Ressourcennutzung und alternativen Materialien und deren Anwendungen.

Success for KIT master students: at the second Urban Mining Student Award cycle, students of the Master course “Glück auf am Theodorschacht” organized and taught by the Professorship of Sustainable Construction at the Faculty of Architecture were extremely sucessfull. They won the first, two 3rd and two recognition prizes.

The age of using fossil resources is coming to an end. Far away from the Ruhr area the last days are counted for the German hard coal mining. The Ibbenbüren colliery in the northernmost tip of North Rhine-Westphalia was one of the last two of its kind and was closed at the end of 2018. The surface facilities of the mine are located at various shaft locations and were asked to be re-designed and reused as a public cultural facility, understanding the existing structures and materials as a new ressource for architectural planning.

The award was organized by the agn Niederberghaus & Partner GmbH together with the University of Wuppertal (BUW) and the Association Urban Mining. It recognizes concepts, ideas and strategies for promoting a consistent circular economy. The reusability of the construction and the recyclability of the building materials, together with the reuse of used components and a high level of repair friendliness, are in the foreground of the considerations. Further criteria were the flexibility of the building structures as a prerequisite for reuse and reuse, low space and water consumption, the highest possible building self-sufficiency with low-tec solutions for operational and energy efficiency as well as the promotion of micro-climate and biodiversity.

Approximately one third of the Cambodian population is affected by extreme poverty; 90 percent of them live in rural areas. That is where we will be working. 60 kilometers north of Phnom Penh lies the village of Mea Nork, 10 kilometers west of Odongk Airport in Cambodia. 

The NGO “Smiling Gecko” has been operating there for several years. Its aim is to support people – most of them migrating from the slums of Phnom Penh – who want to come back to a self-determined life and a free and independent future. To this end, a community based on an agricultural economical system was started in 2014. The people help each other and use the collective as a reservoir for communication and exchange.

Since 2014, our professorship has supported “Smiling Gecko” in the construction of a school for 1,200 students for this community. The aim is to give the children growing up there the chance of an adequate and well-founded school education. Now “Smiling Gecko” has once again asked our professorship for help. The aim is to design, plan and build a kindergarten in the area.

In order to get to know the socio-cultural, ecological, economic and especially climatic conditions better, we undertake an excursion to Cambodia and to the building site near Phnom Penh at the beginning of the semester. The semester is conducted in cooperation with the professorships of structural design and building physics.

Dirk E. Hebel speaks at the BAU Munich 2019 on the conference “Renewable, Rediscovered and Recycled – Materials for Sustainable Construction”. The public debate on the energy balance of construction increasingly focuses on the gray energy of buildings. This refers to the total balance of energy consumed in the manufacture, transportation, processing, use and disposal of building materials. Wood and other renewable building materials and resources are experiencing a comeback, especially in environmentally conscious sectors. The conference “Renewable, Rediscovered and Recycled – Materials for Sustainable Construction” addresses materials in and on buildings that are reusable, biodegradable or renewable, thus ensuring a better climate balance in the construction sector as low-CO2 building materials.

The Alternative Construction Materials Module FCL and the Professorship of Dirk E. Hebel at KIT Karlsruhe has also taken responsibility for design and construction of the second and third phase of the project. Currently the team has finished the production of newly developed bamboo composite elements as an external wall cladding element. The team together with Mycotech from Indonesia has also finished the production and installation of innovative mycelium tiles as an internal wall cladding and is currently finalizing the design for the 3^rd floor of the building, which should be finished also this year.

One year after the completion of the structures and the operational start, Smiling Gecko celebrated the official opening of the Smiling Gecko School together with guests from sponsors, business and administration, and of course the students and their parents in early December 2018. The celebrations stretched over two days. The first day started with a lunch in the kitchen of the new food processing center, open since November 2018, where students and the invited guests got to know each other better. The aim of the second day was to give the guests an insight into the school life of the children.

The architectural project involves the construction of a new school, consisting of 24 classrooms, 15 group study rooms, 3 workshop rooms, an administrative wing, a library, cafeteria, community laundry, community medical clinic, toilets, staff dormitories, an outdoor assembly space, playgrounds and a lake.

The architectural project was designed by Lisa Devenoge, Oliver Faber, Lorine Grossenbacher, Franziska Matt, Elizabeth Müller, and Alina Wyder with Prof. Dirk E. Hebel under the request of the NGO Smiling Gecko.

The publication presents the results of a design and research semester on agricultural monuments of tobacco cultivation in the municipality of Hayna / Pfalz at the Professorship of Sustainable Construction Dirk E. Hebel at the Karlsruhe Institute of Technology (KIT). The work was carried out in close collaboration with the citizens of the municipality Hayna and scientists of the KIT from the areas of structural engineering, building physics, historic preservation and building economics. The studio dealt with the central themes of economic and environmental sustainability, the conscious use of resources and the question of existing social and cultural values ​​and related identities.

For materials that are no longer needed, there was for the longest time only one word: waste. Following this linear mentality of “take, make and waste” the term “disposable society” came up in the second half of the 20th century. With the start of the oil crisis in the 1970s this ideology started slowly to be rethought. Today, people talk less about waste when dealing with materials they no longer need. One speaks of “ressources”. In form of an interview, Werner Sobek and Dirk E. Hebel take their latetst building project UMAR to discuss future concepts of a circular econmy within the built environment. They formulate where in their view future research, teaching concepts and practical work need to address one of the most important questions of the 21st century: where to source the materials to build for more with less.

Im Zuge der Industrialisierung hat sich unsere Bauindustrie verstärkt auf mineralische, endliche Materialquellen konzentriert, die aufgrund des intensiv betriebenen Abbaus unweigerlich zur Neige gehen. Das 21. Jahrhundert ermöglicht nun einen Paradigmenwechsel: Eine Umorientierung vom Abbau zum Anbau zukünftiger Ressourcen. Cultivated Building Materials stellt industrialisierte Wachstumsmethoden und innovative, kultivierte Baumaterialien vor, wie z. B. Zement aus Bakterien, Ziegel aus Pilzmycel oder Bambusfasern als Betonverstärkung. Mit dem Ziel, eine Brücke von der wissenschaftlichen Forschung zur Produktentwicklung und -anwendung zu schlagen, beschreibt das Buch den Beitrag einer breiten Palette von Fachleuten und Innovatoren.

As Addis Ababa creaks under the weight of a mushrooming populace, sub-Saharan Africa’s largest housing project is under way. But who benefits? Wrapped in a white shawl and sporting a wide-brimmed cowboy hat, Haile stares out at his cattle as they graze in a rocky patch of grass. “My family and I have been here since I was a child,” he says, nodding at the small, rickety houses to his right. “But we will have to leave soon.” In the distance loom hulking grey towers, casting long shadows over his pasture. This is Koye Feche, a vast construction site on the edge of Addis Ababa that may soon be sub-Saharan Africa’s largest housing project.
