Renewable, Rediscovered and Recycled – Materials for Sustainable Construction

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.

Tropical Town Project Batam with prototypes of newly developed materials of the Alternative Construction Materials Team of FCL Singapore and the Professorship Dirk E. Hebel KIT Karlsruhe

By 2025, Indonesia will need 30 million houses to house its residents, which means the country needs to build around 1.2 million new houses per year. Access to formal public housing, however, especially for the low-income group, is still elusive due to the cost and the difficulties of securing financing.The Tropical Town project by Singapore Future Cities Laboratory’s Urban-Rural Systems team around Prof. Stephen Cairns aims to develop alternative sustainable settlements that provide affordable housing for the low income inhabitants in developing countries, particularly in the tropics.

The planning strategy of Tropical Town is to integrate small living units with public spaces and productive landscapes. Each unit called Rubah can gather 100% of the rainwater for clean water, manage 100% of liquid and solid waste, afford 60% of the self-sufficient energy which will be integrated with an on-grid system with PLN, and 20% of  food that family needs. The Rubah has been constructed with help of the Alternative Construction Materials Module FCL Nazanin Saeidi and Alireza Javadian and the Professorship of Dirk E. Hebel at KIT Karlsruhe using local building materials such as bamboo, Meranti timber, rammed earth, and mycelium. The kitchen has been designed as a mobile kitchen to provide the opportunity to run a small food business to increase household incomes.

The first phase of Tropical Town was an explorative study conducted through symposiums, workshops and exhibitions in Singapore, the Netherlands, Switzerland, Germany and Indonesia. The second phase of this project is focused on design development, experimental studies and the implementation of the ground floor construction of the Rubah unit along with the provision of the smallest systems in Tropical Town. The third phase will continue with design development, the experimental and construction studies of the Rubah’s upper floors.

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 3rd floor of the building, which should be finished also this year.

The new DGNB Report Circular Economy with contributions from the Professorship of Sustainable Construction at KIT

We are happy to announce the publication of the new DGNB (German Association of Sustainable Construction) report on Circular Economy with several contributions from the Professorship of Sustainable Construction at KIT Karlsruhe, including next to several projects carried out by the team over the past months (UMAR Experimental Unit in Dübendorf, Switzerland and the MycoTree project for the Seoul Biennale, South-Korea) also a pedagocical concept of a new Material Library at the Faculty of Architecture at KIT Karlsruhe.

The concept of a Circular Economy is intended to ensure the availability and quality of resources for future generations through appreciation, reuse and recycling. With the new report, the DGNB want to demonstrate the potential of a circular economy in the construction industry and promote its implementation and integration into construction practice. The publication is dedicated to the responsible use of resources and the manifold requirements of a circular economy in the context of building planning, implementation and use.

Official opening of the Smiling Gecko School Cambodia

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.

take. build. repeat. symposium for resource-respectful construction.

take. build. repeat. Symposium für ressourcengerechtes Bauen.
09.11.2018 / 9:30 – 18:00 Uhr

Fachgebiet Nachhaltiges Bauen
KIT Karlsruher Institut für Technologie
Egon-Eiermann-Saal, Englerstr. 7, Geb. 20.40

The symposium take.build.repeat. questions the currently practiced throw-away mentality of today’s construction industry: Resources are taken, consumed and subsequently disposed of. Contrary to this linear concept of ressource destruction are ideas of closed material cycles, of newly conceived (re-)building technologies and, in particular, new business models of the circular economy. The symposium addresses the important question of how we can build our cities of the future in times of ever-growing global population and increasing resource scarcity without continuing to exploit and pollute our natural environment. The built environment must represent both a responsible present-day solution as well as the material bank for the future.

The one-day symposium will bring together representatives of science and industry, theoretical and practical approaches as well as practitioners and students to jointly shape the future of building through lectures and discussions. Speaking will be Prof. Dr. Werner Sobek (Werner Sobek Group / University Stuttgart), Prof. Dr. Walter R. Stahel (Product Life Institute), Prof. Annette Hillebrandt (University of Wuppertal), Peter van Assche (Bureau SLA), Jasper Brommet (StoneCycling), Stefan Rohrmus (Schüco) and Sabine Oberhuber-Rau (Madaster). The recently opened Urban Mining and Recycling unit (UMAR) at the Empa NEST in Switzerland by Werner Sobek with Dirk E. Hebel and Felix Heisel will be presented in detail.

The event on 09. November 2018 is organized by Sustainable Construction at the Faculty of Architecture of the Karlsruhe Institute of Technology KIT and is recognized as Weiterbildungsmaßnahme by the Chamber of Architects Baden-Württemberg with 4 hours.

MycoTree nominated for Beazley Design of the Year Award 2018

Our 2017 MycoTree for the Seoul Biennale of Architecture and Urbanism is nominated for the Beazley Design of the Year 2018 Award. #BeazleyDesignsoftheYear

MycoTree is a spatial branching structure made out of load-bearing mycelium components. Its geometry was designed using 3D graphic statics, keeping the weak material in compression only. Its complex nodes were grown in digitally fabricated moulds.

Utilising only mycelium and bamboo, the structure represents a provocative vision of how we may move beyond the mining of our construction materials from the earth’s crust to their cultivation and urban growth; how achieving stability through geometry rather than through material strength opens up the possibility of using weaker materials structurally and safely; and, ultimately, how regenerative resources in combination with informed structural design have the potential to propose an alternative to established, structural materials for a more sustainable building industry.

MycoTree is the result of a collaboration between Sustainable Construction at Karlsruhe Institute of Technology (KIT), the Block Research Group at the Swiss Federal Institute of Technology (ETH) Zürich and the Alternative Construction Materials Unit of the Future Cities Laboratory Singapore. It was the centrepiece of the “Beyond Mining – Urban Growth” exhibition at the Seoul Biennale of Architecture and Urbanism 2017 in Seoul, Korea curated by Hyungmin Pai and Alejandro Zaera-Polo, and was on display in Pavilion i7 at the Donuimun Museum Village from September 1st 2017 to March 31st 2018.

Bauwelt 14.2018: Interview with Werner Sobek and Dirk E. Hebel

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.

Buchvorstellung CULTIVATED BUILDING MATERIALS

 
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.

The making of UMAR

One working day, two cranes and a well attuned team: on 21 November 2017, the woodworkers from the Austrian company Kaufmann Zimmerei und Tischlerei placed the seven prefabricated modules of the Urban Mining and Recycling unit with utmost precision between the projecting platforms of NEST, the research and innovation building of Empa and Eawag in Dübendorf. The interior finishing was implemented in the following few days; and the apartment thus ready to accommodate its first two tenants. Read more here.

Urban Mining and Recycling opened at Empa NEST

Prof. Dr. Werner Sobek, Government councillor of the Canton of Zurich Markus Kägi, NEST Innovation Manager Enrico Marchesi, Prof. Dirk E. Hebel and Felix Heisel (Photo Empa)

On February 8th 2018, Werner Sobek, Dirk E. Hebel and Felix Heisel officially opened Urban Mining and Recycling UMAR, the newest addition to the Empa NEST. The project is underpinned by the proposition that all the resources required to construct a building must be fully reusable, recyclable or compostable. This places life-cycle thinking at the forefront of the design: Instead of merely using and subsequently disposing of resources, they are borrowed from their technical and biological cycles for a certain amount of time before being put back into circulation once again. Such an approach makes reusing and repurposing materials just as important as recycling and upcycling them (both at a systemic and a molecular/biological level, e.g. via melting or composting). This conceptual emphasis means that UMAR functions simultaneously as a material laboratory and a temporary material storage.

MycoTree in Dezeen’s top 10 list of unusual materials

In 2017, a number of designers explored the structural properties of new, environmentally friendly materials – but mushroom mycelium was one of the most unusual. It was used to create a tree-shaped self-supporting structure in South Korea.

The Guardian: Addis has run out of space

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.

Construction starts at NEST Unit Urban Mining & Recycling

One working day, two cranes and a well attuned team: on 21 November 2017, the woodworkers from the Austrian company Kaufmann Zimmerei und Tischlerei placed the seven prefabricated modules of the new “Urban Mining & Recycling” unit with utmost precision between the projecting platforms of NEST, the research and innovation building of Empa and Eawag in Dübendorf. The interior finishing will be implemented in the next weeks. The apartment will be ready in the spring of 2018 and will accommodate two tenants.

The NEST unit “Urban Mining & Recycling” is simultaneously an apartment, a material storage, and a material lab. The unit is based on the idea that all resources required to construct a building must be fully reusable, recyclable or compostable. Werner Sobek, director of the Institute for Lightweight Structures and Conceptual Design of the University of Stuttgart and owner of the Werner Sobek Group, together with Dirk E. Hebel and Felix Heisel of the Chair of Sustainable Construction at the Karlsruhe Institute of Technology (KIT), are responsible for the design. The general contractor of the project is Kaufmann Zimmerei und Tischlerei. The seven modules that form the new unit were prefabricated in their factory in the Reuthe, Austria.

The structure as well as large parts of the facade are made of untreated wood. The innovation lies in the connections and the material-oriented use: all connections of the system subjected to tension and compression can be easily undone. Adhesive connections had been omitted in favor of plug and screw connections. The wood being used is applied in such a way that an otherwise standard coating is not necessary, thus making purely type-sorted recycling or purely biological composting possible.

Recycling stones and borrowed floor slabs

The facade consists of aluminum and copper. Both metals can be melted and recycled according to type. Inside, various serially-processed building products had been used, the different materials of which can be recycled in a type-sorted manner and without residue. Among other things, grown wall panels consisting of mushroom-based mycelium, innovative recycling stones, recycled insulation materials, as well as borrowed floor coverings are also being used in the unit. Through the use of such new “material leasing concepts“, the construction of this unit also calls into question the existing economic concepts prevalent in the construction industry. During a second construction phase, the unit will then also address research questions regarding the sustainable use of energy through a retrofittable solar heating system.

The “Urban Mining & Recycling” unit will be connected to the NEST backbone and the interior will be completed in the coming weeks. The official opening of the unit will take place in early February 2018. Shortly thereafter, the first two tenants will move into the new residential unit and subject the materials to a practical test.

    Cultivated Building Materials: Industrialized Natural Resources for Architecture and Construction

    June 12, 2017

    Hebel, Dirk E. and Felix Heisel (2017). Cultivated Building Materials: Industrialized Natural Resources for Architecture and Construction. Birkhäuser: Berlin.

    The 21st century will face a radical paradigm change in how we produce construction materials – a shift towards cultivating, breeding, raising, farming, or growing future resources. The book presents innovative cultivated building materials, like cement grown by bacteria or bamboo fibers as reinforcement for concrete. The book aims to build a bridge from scientific research to product development and application.

     
     

    Die Zukunft ist aus Bambus

    June 11, 2017

    Reimann, Milena (2017). Die Zukunft ist aus Bambus. Rheinische Post: Düsseldorf.

    Aus dem holzähnlichen Gras werden immer mehr Produkte gefertigt – vom Fahrrad übers Kleid bis zum Toilettenpapier. Jetzt wollen Forscher sogar moderne Häuser aus dem Werkstoff bauen. … Auch Dirk Hebel ist begeistert von dem Rohstoff. Er ist Architekturprofessor mit dem Schwerpunkt “Nachhaltiges Bauen” am Karlsruher Institut für Technologie. Statt wie bisher Häuser aus Stein und Stahl zu errichten, wollen er und sein Team Gebäude aus gepressten Bambusfasern bauen. More information here.

     
     

    Wie Sand am Meer?

    June 1, 2017

    Hellge, Anna (2017). Wie Sand Am Meer?, in: natur (07/17): 44 – 49.

    Nicht nur Wüstensand aus Mauretanien macht beim Bauen oder im Küstenschutz Probleme. Dirk Hebel, Professor für nachhaltiges Bauen an der Uni­versität Karlsruhe, erklärt das Phänomen: ,,Zwar ist Sand genau die Zutat, die der Beton benötigt – aber Sand aus der Wüste eignet sich nicht zur herkömmli­chen Betonproduktion.” Stattdessen sind dafür Sän­de aus Meeren, Seen oder Flüssen nötig. Der Grund dafür liegt im Detail: ,,Sie müssen sich diese Sande nur einmal unter der Lupe anschauen”, sagt Hebel. „Sie werden feststellen, dass die Körner, welche durch Bäche und Flüsse in unsere Meere getragen wurden, scharfkantig und gebrochen sind.” Nur die­se kantigen Körnchen können durch hohe Reibungs­widerstände Druckkräfte aufnehmen und weiterlei­ten und machen -salopp gesagt -Beton überhaupt erst belastbar. In der Wüste schmirgeln sich die Sandkörner dagegen glatt und sind zur Betonherstel­lung so nicht brauchbar. ,,Wüstensand verhält sich wie eine Hand voll Murmeln”, erklärt Hebel.

     
     

    ADDIS 5000 – Design Studio Publication

    May 12, 2017

    Hebel, Dirk E., Patrick Chladek, Amelie Fibicher, Philippe Jorisch, Felix Heisel, Sophie Nash, Hans Rufer, Gian Salis, Marta H. Wisniewska (2017). ADDIS 5000, Design Studio Publication Fall 2014, 01/05, ETH Zürich, Switzerland.

    Addis 5000 proposes the creation of 5000 new living units in the Ethiopian capital of Addis Ababa in close collaboration with the city administration. Faced with an increasing unavailability of globally-favoured and expensive building materials and construction methods, the city government is in desperate need of alternative housing solutions that embody the country’s long and complex history, the immense cultural identity, and the unique characteristics of a society under transformation.

    Ressource Schweiz applies the fundamental principle of exploring local possibilities and opportunities within the territory of Switzerland. Students are partnered with a Swiss craftsperson specializing in a distinct craft utilizing a unique local building material. Intensive visits to the craftsperson and associated region are required to gain an understanding of the material’s application and manufacture as well as to establish a dialogue between the craftsperson, the site, the material and the student.

     
     

    Village School Project Cambodia – Design Studio Publication

    Village School Project Cambodia operates within one of the most crucial fields of sustainable action: the education sector in developing territories. Based on a thorough understanding of an appropriate pedagogical model developed in collaboration with the Pedagogical University of Applied Science in Zürich, students are asked to design an educational facility for 1000 students in a rural area, just north of the Cambodian capital Phnom Penh.

     
     

    Building for Disassembly – Design Studio Publication

    May 12, 2017

    Hebel, Dirk E., Patrick Chladek, Amelie Fibicher, Philippe Jorisch, Felix Heisel, Sophie Nash, Hans Rufer, Gian Salis, Marta H. Wisniewska (2017). Building for Disassembly, Design Studio Publication Spring 2016, 04/05, ETH Zürich, Switzerland.

    Building for Disassembly, aims to produce a paradigm shift within the construction industry. Instead of working within a linear system of “produce-use-discard”, students are asked to develop new construction methods and principles which follow the concept of a circular economy. Designing for disassembly is perceived as a proactive solution to both the shortage of resources and the minimization of waste. Cities can therefore be simultaneously consumers and suppliers of resources and use themselves for their own reproduction.

     
     

    Living Lab Zakynthos – Design Studio Publication

    Living Lab Zakynthos asks the students the most obvious and yet most difficult question operating in the field of sustainable construction: how to define their own and individual hypothesis of the theme. Seeking clarity in this definition, students are asked to design a hotel complex on the west coast of the Greek island of Zakynthos, on a site sloping down towards the Ionic Sea.

     
     

    Neformálnosť v knihe i krajine

    April 3, 2017

    Czafík, Michal (2017). Neformálnosť v knihe i krajine, ARCH Magazine 1-2/2017(Architektúra a bývanie): 59–60.

    Book Review of Lessons of Informality in Slovakian Magazine ARCH:
    Who would I recommend the book to? All who have the desire to indirectly find their way into life in a country that is still covered with a riddle of mystery. Urban designer, architect, sociologist, cultural scientist, anthropologist … I could continue to name myself. This confirms only one fact, that architecture has long been not only a mono-, but a multidisciplinary issue.

    We say thank you!
