“Sustainable Architecture” – Scientists for Future Podcast

The Scientists for Future podcast features monthly conversations with scientists about climate change, sustainability and a livable future.

The building sector is responsible for around 40% of CO2 and greenhouse gases in Europe. The Scientists for Future took this initial situation as an opportunity to join forces with the Architects for Future and dedicate an episode of their podcast to the topic of architecture. To do so, they invited Prof. Dirk Hebel from Professorship of Sustainable Construction at the Karlsruhe Institute of Technology.

“We have to understand our buildings as material stores,” he describes. In addition to the question of raw material consumption and the circular economy, the current podcast episode also talks about urban planning and the new European Bauhaus. Svenja from S4F and Leonie from A4F Kassel also discuss with their guest how architecture and our coexistence must change for a sustainable future. Because it turns out: How we build is not only a technical question but also a cultural one.

The current episode of the Scientists-for-Future-Podcast “Sustainable Architecture” is available here.

The Professorship of Sustainable Construction represented in the lookKIT magazine “BAUEN”

In this year’s third edition “BAUEN” of the KIT magazine for research, teaching and innovation “lookKIT”, three different articles report on research and other topics taking place at the Professorship of Sustainable Construction at the Karlsruhe Institute of Technology.

“We Have to Build Simpler, Purer and Smarter” © lookKIT

Under the title “Realizing recycling-oriented Construction”, Dr. Stefan Fuchs conducted an interview with Prof. Dirk E. Hebel, Sandra Böhm and Daniela Schneider from the Professorship of Sustainable Construction. The topics of the conversation range from the protection of resources to the problem of land consumption and the need for new forms of living. According to the researchers, in order to anchor the circular economy in construction, it is also necessary to use biological materials in order to close the resource gap.

The spread of such materials can be promoted by including environmental costs in materials of fossil origin. In addition, architects have to start planning again with traditional and other simple joining techniques in order to ensure the correct use and quality-preserving dismantling of materials. Hebel, Böhm and Schneider place great hopes in the introduction of a material pass to anchor digitization and documentation in the construction industry. Finally, the author also points out a video with Prof. Dirk E. Hebel on the question “Why build sustainably?”.

“The Future City as Resource Supply” © lookKIT

In “The Future City as Resource Supply” by Sandra Wiebe, the RoofKIT team demonstrates that it is possible to integrate the building sector in a functioning circular economy. Taking part in the Solar Decathlon Europe 2021/22 the team is developing a concept for heightening the roof of Café ADA in Wuppertal. In a reduced on-scale version, they will realize their project on the Solar Campus in Wuppertal in June 2022.

The project is composed of three important topics of the implementation of circular economy in the construction sector: to use the built environment as a new mine, to enable buildings to be fully disassembled after use and to harvest energy sustainably in order to reach climate neutrality. According to the head of project Prof. Dirk E. Hebel, RoofKIT’s design is of relevance to novel, socially centered living spaces supporting future-oriented urban society.

“The Construction Sector needs a Radical Turnaround” © lookKIT

Two architecture students campaign for a sustainable future of the construction sector as a whole with their newly founded local group of the “Architects for Future” in Karlsruhe. Alisa Schneider and Elena Boerman both did their master thesis on adaptive reuse projects at the Professorship of Sustainable Construction in summer 2021.

The author of the article, Regina Link, points out their central focus of a radical turnaround in the construction sector. In the name of their Germany-wide association, the two graduates call on people to consider the entire life cycle of buildings and thus break through the linear system of construction. Society must become aware of the value of buildings and the resources they contain: The goal must be to make building and rebuilding a circular system in which waste no longer exists and materials are used in and removed from buildings for reuse and recycling.

An online version of the article is available here. Find out more about the association Architects for Future here.

“A home for the future – climate-friendly building and living” – WELTWUNDERKUGEL podcast by SWR

The climate podcast WELTWUNDERKUGEL from SWR deals with topics related to the function of our planet. The makers are interested in understanding what defines our earth and the climate and how we can hand over a healthy earth to future generations.

The current episode “A home for the future – climate-friendly building and living” is about sponge cities, high-rise forests, eco-villages and biological building materials. In the search for the “Home of the future”, voices from science and society are heard and various projects on the topic are presented by the SWR1 editor Christiane von Wolff.


In this context, Dirk E. Hebel from the KIT Professorship of Sustainable Construction addresses the idea of sustainable development. He also reports on the many possible uses of mushroom-based materials in the construction industry and on dealing with today’s building stock. “Garbage as a design error” is the keyword here: it is important to understand that the consistent recycling economy in the construction industry is the only way to seriously implement resource conservation in the construction industry.

“Urban Mining” – Die Sendung mit der Maus

How do we want to live in the future? And how can we also be sure in the future that there will be enough raw materials to provide everything needed in daily life? Clari, Jana, Ralph and André from the “Sendung mit der Maus” are looking into securing raw materials and urban mining.

For this purpose, they are opening a future flat-sharing community for four weeks in the Urban Mining and Recycling Unit in the NEST research building on the EMPA campus in Dübendorf, and from there they are exploring where and how the various components of the research unit were produced.

The four-part series Urban Mining from “Die Sendung mit der Maus”

The first part is about the recycling of bricks into new masonry units. The focus is also on the MycoLab of the KIT in Karlsruhe and the production of insulating material from mycelium there. The second episode shows the viewers the production process of glass ceramics and plate material from melted plastic. The third episode deals with the production of table tops from used beverage cartons and with recyclable carpets. The fourth episode focuses on technical innovations and the deconstruction of materials from urban mining.

The four-part series “Urban Mining” from the “Sendung mit der Maus” conveys an understanding of the responsible use of our raw materials in a child-friendly way.

At the “Door opener day with the mouse”, the 3 October 2021, upcoming ideas, innovative plannings, exciting projects and much more will be presented to children under the motto “Hello Future” all over Germany. One of the numerous participatory activities will take place at the KIT in Karlsruhe.

At the MycoLab at KIT, the Professorship of Sustainable Construction at the Faculty of Architecture, Prof. Dirk Hebel, is conducting research on alternative building materials. The team is working on the conversion of organic waste into alternative, cultivated and biological building materials. This involves the use of mycelium, the route of mushrooms, which is fed with biological waste so that stable, pressure-resistant forms can subsequently be realized. 

Impressions of the MycoLab © Professorship Sustainable Construction

The MycoLab has already been featured by ZDF PUR+ last year, and in the program “Sendung mit der Maus” on its 50th anniversary a few months ago.

On the “Door opener day” the MycoLab team aims to show the participating children how alternative sustainable resources can be regrown faster than wood without any negative impacts on our forests and biodiversity as well as our climate by utilizing the wood and agricultural waste resources and turning them into sustainable, biobased and green building materials with the power of mushrooms.

In the middle of June, NEST Innovation Manager Enrico Marchesi invited Prof. Dirk E. Hebel and Sandra Böhm from the Professorship of Sustainable Construction to present the housing unit, the building materials used there, and the construction and material concept to the viewers of the “Sendung mit der Maus” after a brief welcome. The Urban Mining and Recycling Unit of the EMPA is still one of a few lighthouse projects of circular construction. Many innovative, forward-looking construction techniques are used in exemplary applications, which allow the sorted disassembly and the later reuse of all used materials. The unit was created in 2017 by Werner Sobek with Dirk E. Hebel and Felix Heisel, Bernd Köhler and Frank Heinlein.

Two winners of the aed neuland 2021 at the Professorship of Sustainable Construction

Regina Gebauer and Anne-Catherine Greiner are two of a total of ten winners of the aed neuland 2021 young talent competition in the Architecture and Engineering category. They each received the silver award for their semester designs, which were both created at the Professorship of Sustainable Construction at the Karlsruhe Institute of Technology and were supervised by Prof. Dirk E. Hebel, Manuel Rausch and Daniel Lenz.

In her project “Bis sich alles bewegt” (“Until Everything Moves”), Regina Gebauer deals with the inward densification of urban spaces in European city centres in an exemplary manner in terms of sustainability. The addition to an existing building in Wuppertal with the clear formulation of the joint between old and new convinced the jury. With the consistent implementation of the themes of circular economy in construction, single-variety construction and the Urban Mine, it demonstrates a self-confident architectural stance.

Find out more about the project here.

Anne-Catherine Greiner proposes a playful solution for the Mea Nork kindergarten of the NGO “Smiling Gecko” near Phnom Penh in Cambodia as an extension of the existing school. Taking into account climatic conditions and honouring local community and ecosystems, the organic structure offers children the opportunity to learn with and from each other. By using natural materials and applying local building traditions, it shows a way to address environmental and social issues through architecture.

Urban Mining and Circular Construction

Book Cover © Martin Kjer, Fraunhofer IRB Verlag

The book “Urban Mining and Circular Construction. The city as raw materials warehouse”, published in May 2021, edited by Dirk E. Hebel and Felix Heisel, questions the throwaway mentality currently practiced in the construction industry: raw materials are taken from established natural cycles, used and then disposed of without using or even recognizing their potential for continuous value creation.

Materials are consumed and used instead of being borrowed from biological or technical cycles and then returned there. This linear approach has profound consequences for our planet. We are fundamentally changing existing ecosystems.

International experts examine from very different perspectives, and on the basis of future-oriented project examples, how this paradigm shift can succeed and how the technical, logistical and organizational challenges of a circular economy can be met with completely new methodological approaches. A collection of selected material examples shows the special aesthetics and value of reused and recycled building materials and components.

Through positive incentives and impulses, the book shows possible ways to a circular construction industry – because a complete circular economy must become the central and common goal of our society in order to conserve our natural resources.

In addition to Dirk E. Hebel from the Professorship of Sustainable Building at KIT, Katja Fischer, Roland Gruber, Jörg Heiler, Ayşin İpekçi, Maria Isabettini, Simon Jüttner, Jan Kampshoff, Kamiel Klaasse, Andreas Krauth, Urs Kumberger, Tabea Michaelis, Peter Nageler, Michael Obrist, Ben Pohl, Eike Roswag-Klinge and Verena Schmidt are among the participating architects and urban planners.

The exhibition of the Bund Deutscher Architektinnen und Architekten BDA was curated by Olaf Bahner, Matthias Böttger and Laura Holzberg. They invite you to read the permanence of what has been built and what has grown and plead for further thinking and careful repair of living spaces and living cultures. They show how new perspectives arise in the urban and regional context through networked approaches, through cooperation oriented towards the common good and through participation concepts. For the future, the buildings erected today, strategies for the circular use of materials and an openness to future requirements are being developed.

The exhibition takes places in the DAZ in Berlin from 03 December 2020 until 27 June 2021. Visiting the exhibition is possible again since 21 May 2021.

“How will we live together?” – La Biennale di Venezia

From 22 May until 21 November 2021 La Biennale will take place in the Arsenale and the Giardini in Venice. The curator Hashim Sarkis calls on architects to imagine spaces in which we can generously live together in different ways, in the context of widening political divides and growing economic inequalities.

Last year, the team ‘ETH Zurich | KIT Karlsruhe | EiABC Addis Ababa’, led by Marc Angélil and Dirk E. Hebel, developed a contribution entitled “Quo Addis? Conflicts of Coexistence” to the major architecture exhibition. In an urban model of Addis Ababa, the historical and architectural development of the Ethiopian capital from the age of Menelik’s empire in the 19th century until today is depicted in an abstract and at the same time precise and clear way. A film produced by Jenny Rodenhouse completes the exhibition contribution and brings the visitor closer to life and coexistence in the different quarters of the city.

The entire installation was brought to Venice at the end of April by a team of six around Dirk E. Hebel and Katharina Blümke and was set up in the Arsenale. The construction of the model was documented by the team in a short film:

Urban Mining – New episode of the RoofKIT podcast “Fighting 40%”

The podcast “Fighting 40%” was created as a part of the international competition Solar Decathlon Europe 21. The RoofKIT podcast team presents topics relating architecture and urban design, but above all sustainability and future-oriented thinking.

In the current second episode released on 10 Mai 2021, two podcast team members discuss about “Urban Mining” with Prof. Dirk E. Hebel, the Faculty Advisor of team RoofKIT.

Podcast “Fighting 40%”, episode “Urban Mining” © Team RoofKIT

Since the post-war period, we have been surrounded by an anthropogenic warehouse of over 50 billion tons of material. This warehouse grows every year by another 10 tons per inhabitant. Much of it is located in buildings. Wouldn’t this warehouse be a potential resource for the construction industry of the future?

“The construction industry needs a radical turnaround”

The two architecture master’s students Alisa Schneider and Elena Boerman report in the KIT student magazine clicKIT about their activities in the local group of the nationwide association Architects for Future in Karlsruhe.

In their work, the two are committed to ensuring that the building industry experiences a sustainable and future-oriented turnaround. Among their demands as Architects for Future are the critical questioning of building demolitions, the increasing use of healthy, regional and climate-positive materials instead of cheap and foreign materials, circular construction and the perception of the urban mine as a storehouse of materials, as well as the preservation and creation of living spaces by avoiding new land sealing.

‘On Cities’ Masterclass Series

The Norman Foster Foundation (NFF) presents the ‘On Cities’ Masterclass Series, a series of thirty-minute-long masterclasses which explores the most pressing and compelling topics related to contemporary cities. Given by twenty leading experts in the fields of architecture, urbanism, economics and mobility, this video series supports the NFF’s extensive educational programme by promoting an exchange of knowledge across a range of geographic and disciplinary perspectives.

Although cities may offer significant advantages for inhabitants, urbanisation is widely regarded as one of the fundamental challenges for public health, social equity and sustainability. To meet these challenges, speakers touch themes such as urban leadership, equity, urban informality, urban food systems, urban sustainability, urban materiality, urban mobility, and urban economics, among other key topics.

© Norman Foster Foundation

In his introductory masterclass to the series, Norman Foster (President, Norman Foster Foundation) considers the future of cities and the crises that cities have overcome throughout their history, arguing that the current pandemic has accelerated important trends already in motion, such as a return to green and open public space and compact urban areas that provide inhabitants with services and leisure within a walking distance:

RoofKIT – On what the team is addressing, what the goals are and how it intends to achieve them

Urbanisation in Europe reached approximately 75%, and the tendency is growing; thus, European cities face several urgent problems, which should be solved to comply with the EU targets to fight climate change.

To name a few critical problems aligned with the scope of the project: 

  • Available living space is getting rare within the existing boundaries due to the increasing rate of migration from people into cities and the constant growth of the consumption of square meter per person.
  • Environmental quality in cities is strongly affected by pollution, mainly caused by combustion (traffic, heating), and increasing temperatures as well as heat waves during the summer due to urban heat island effects.
  • Most buildings of the existing building stock in European cities were built with a low energy efficiency standard which results in high energy consumption (mostly for heating) and related CO2-emissions.
  • Lastly, the building materials are not only slowly getting scarce and affect the quality of the living spaces, but the building sector is also responsible for a large amount of waste.

To tackle this, Team RoofKIT choses a holistic approach: The extension of buildings with an additional living unit requires combined urban design and architectural strategies, considering the specific requirements of the site but at the same time seeking a more general solution regarding adding living units on cities’ rooftops. RoofKIT‘s goal here is to take up the local potentials of the site and neighbourhood and improve it together with the building design by creating synergies. Together with the outdoor space, the extension will be an exemplary project that will fit into various other contexts in the neighbourhood, the city, and beyond, thanks to ist modularity. It is important that the outdoor space makes no distinction between residents, neighbours or visitors enabling flexibility, multiple uses, capacity, creativity and freedom of use.

Whole Building Design Approach
Although topping up allows creating living space with very low impact on neighbours and users of the existing building, RoofKIT decided to enhance the current situation and to upgrade the existing building by economic, social and energetic terms. Therefore, the interior layout is revised according to the needs of the different functions. Based on the analysis of the existing functions of Café Ada, strategies have been developed to strengthen them further: The ball room that attracts tango dancers from all parts of the world as well as theexisting sleeping facilities for them are not appropriate to the situation.  For this reason, an ‘urban gap’ is created, which forms a transition between the existing structure and the extension and presents the dance hall to the public. The load bearing structure from the early 20st century will be further used and partly reinforced.

Whole Building Design Approach © Team RoofKIT

House Demonstration Unit Design Approach
In order to transfer the concept from the overall building to the house demonstration unit, RoofKIT has chosen the southwest corner of the building as a cutout. It is perceived as a two-story structure that represents the two main components of our building: The residential units and the urban gap. Just as in the overall design, the HDU is built in modular timber construction and consists of a total of four modules. The module that is placed in front of the others in a transverse direction functions as a terrace and represents the shared spaces of our building design. Inside, the interior design is also characterized by modularity in the form of custom-made furniture, which allows flexibility and is especially space-saving at the same time. Furthermore, the open floor plan allows for high space efficiency since no pure traffic zone exists.

Structural Design
The challenge for the RoofKIT design is to base on an already existing building, whose bearing structure has almost reached its load limits. The structural design of the project keeps the established building almost free from additional loads. This works because the thick external brick walls bears the load of the addition. An examination of the walls and foundations will show whether they need to be strengthened. The internal supporting structure has to be reinforced, to bear the increased live loads of the ball room in the urban gap. To keep the additional loads for the top-up to a minimum, a lightweight wooden frame construction was chosen.

Solar System Integration
As the RoofKIT top-up is a new construction with a high energy efficiency standard, the total energy demand (including appliances and e-mobility) will be covered by solar systems on the building envelope. As part of the goal, the sizing of the RoofKIT’s PV and battery system will focus on a high self-coverage of the energy demand as well as on stabilising effects of the grid. In other words, the feed-in of surplus electric energy during solar peaks and heavycharging of grid energy during peak load times will be avoided by a smart building energy management including the building and mobility solutions. A balanced energy threshold over the year (consumption and generation) as a function of available solar radiation, actual energy demand and grid requirements will be achieved by load shifting or any other sort of demand-side management. RoofKIT does not regard the use of solar systems as a mere necessity but as a possibility to design the building on an architectural level.

Urban Mining & Recycling (UMAR) on Instagram @neweuropeanbauhaus

The Urban Mining and Recycling unit (UMAR) in NEST was listed as a showcase project of circular construction by the New European Bauhaus on 6th April 2021. The project shows how a responsible approach to dealing with our natural resources can also go hand in hand with an appealing architectural form. Life-cycle thinking has led the design process: all the resources required to construct the unit are fully reusable, recyclable, or compostable.

Instagram Post about UMAR © neweuropeanbauhaus

The Urban Mining and Recycling housing and research unit in NEST, the modular Research and Innovation Building of Empa in Dübendorf (Switzerland), is demonstrating what a paradigm shift in the construction industry reacting to the limitation of the world’s natural resources might look like. Turning away from linear material-consumption and towards an economy of material recycling, multiple use, alternative construction methods and the use of entirely separable materials – UMAR works as a material laboratory but also as a material depot. It is a proof that the responsible use of natural resources, the recycling of materials and modern architecture can go hand in hand.

The building design was created by Werner Sobek in collaboration with Dirk E. Hebel and Felix Heisel, Bernd Köhler and Frank Heinlein.

planet e. by ZDF: The trick with the rubble

The current episode of planet e., a documentation series by ZDF, examines the state of sustainability in the German construction industry and shows perspectives for building with recycled concrete and products out of construction waste.

The KIT Faculty of Architecture © planet e. (ZDF)

This is because the construction industry in Germany is responsible for more than half of the waste generated, accessible raw materials are becoming increasingly scarce, and the production of building materials such as cement causes greenhouse gases that contribute significantly to the warming of the atmosphere. Nevertheless, construction waste in Germany still ends up in landfills to a large extent. Only a few companies in Germany work in the sense of a circular economy when demolishing buildings and take the responsible initiative to recycle the resulting materials.

Urban Mining and Recycling Unit, EMPA Zurich © planet e. (ZDF)

The editors compare German laws with those in other European countries and highlight what the German “Kreislaufwirtschaftsgesetz” could achieve. For example, in the Netherlands or Switzerland, sustainable construction with innovative building materials and assembling methods is particularly important in the construction of public buildings. In this sense, the Urban Mining and Recycling Unit of the EMPA in Zurich has been established, which is one of a few lighthouse projects of circular construction.

Dirk E. Hebel, sustainability researcher, architect and professor at the Faculty of Architecture at the Karlsruhe Institute of Technology, was also involved in this project. He calls for a clear and responsible change of course in the German construction industry. The increased use of recycled materials and renewable raw materials as the basis for the building materials of the future, such as the fungal mycelium he is researching with his team at the Karlsruhe laboratory, are inevitable and are imminent for the construction industry in Germany.

Xenius by arte: Future building materials

In a new episode of Xenius by arte, the hosts Dörthe Eickelberg and Pierre Girard set out in search of alternative building materials.

Future building materials: Mycelium, paperboard and popcorn © arte

Up to now, the building industry has mainly used concrete and steel. In order to be able to build more ecologically and sustainably in the future, scientists are looking for alternative building materials. And there are some innovative ideas. Mycelium, paperboard or popcorn – nothing is impossible!

Interview with Prof. Dirk E. Hebel © arte

The hosts also interview Prof. Dirk E Hebel about his research with mycelium as an alternative, cultivated biological building material. The mycelium is simply fed with biological waste and can be shaped into stable, pressure-resistant forms. In the Urban Mining And Recycling Unit, which was created in collaboration with researchers from the ETH Zurich, many other innovative, forward-looking construction techniques are also used in exemplary applications, which allow the sorted disassembly and the later reuse of all used materials.

In this episode of Xenius, some other ideas for future building materials are presented. For example, scientists of the Technical University of Darmstadt are researching a way to build houses out of cardboard without any additional wood coatings or protective foils. In Munich, a visionary architect is growing trees into each other in such a controlled way that load-bearing structures are formed that will support bridges or even entire houses years later. Prof. Alireza Kharazipour in Göttingen aims to replace plastic materials as much as possible with the renewable raw material corn.

UMAR and Mycelium Research in “Die Sendung mit der Maus”

In the current 50th anniversary episode of “Die Sendung mit der Maus”, Armin Maiwald, one of the hosts, is looking for how people will live in the future. Therefore he visits the Urban Mining and Recycling Unit (UMAR) created by Werner Sobek with Dirk E. Hebel and Felix Heisel.

The building design demonstrates how a responsible approach to dealing with our natural resources can go hand in hand with appealing architectural form. 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. In that way UMAR functions simultaneously as a material laboratory and a temporary material storage.

After having visited UMAR, Armin Maiwald also takes a look at the mycelium laboratory in the Westhochschule in Karlsruhe. Here our researcher Dr. Alireza Javadian shows the TV host of the children’s program how the mycelium grows in the laboratory, how it is shaped and how resistant it is afterwards.

Results of the Stegreif: “Lern doch wo du willst”

In form of a “Stegreif”, the Professorship of Sustainable Construction jointly with the KIT Zukunftscampus, launched a competition for future outdoor learning spaces at KIT campus. A structure was to be designed that would enable learning and working in an outdoor environment. The design was to be independent of a specific location but should be considered as a flexible object for many possible spots and create a recognizable landmark for the KIT community.

RoofKIT – KIT team participates at the Solar Decathlon Europe 21 competition within the field of sustainable construction

“The future city makes no distinction between waste and supply.”
Joachim Mitchell, New York

How can we create social-economic fair living space without destroying our natural resources? And how can we create ecologically sensitive building structures, acknowledging the finite state of natural material supplies, and avoid any state of “waste”, but understand the existing building stock as an urban material bank for the future? How can we create alternative solar harvesting systems as part of an urban mining ideology and propose paradigm-shifting innovations as first-of-their-kind worldwide? And how can we apply urban mobility systems as an integrative part of the immobile building sector?

The Solar Decathlon Europe 21 (SDE21) is a publicly held competition for sustainable building and urban living, which will take place in 2022 in Wuppertal, Germany, where it will be judged. The motto: „design-build-operate.“ This means that, unlike in other architectural competitions, the participating teams will actually build their designs. The aim of the competition is to find innovative and at the same time tangible solutions to the technical, architectural and social problems we face in our cities.

The first Solar Decathlon in 2002 in Washington D.C. © Solar Decathlon

The first Solar Decathlon was held in 2002 by the Department of Energy of the United States on the National Mall in Washington D.C., followed in 2010 by the first European version in Madrid. With the SDE21 comes the world‘s 21st edition of the competition for the first time to Germany – with a new and urban profile and the question of how we should deal with limited ressource in future constructions and how to apply the necessery and politically demanded concept of a circular economy within the building industry.

18 university teams from 11 countries will construct fully usable demonstration units of approx. 80 sqm each on the Solar Campus in Wuppertal which is locatad on the Utopiastadt site in 2022. The teams will compete with their buildings in 10 different disciplines. 

The RoofKIT team of the KIT Faculty of Architecture will address those urgent questions in the competition by exploring a gigantic surface resource within our cities: rooftops. By applying the idea of the circular economy towards the identification of new possible building sites within our cities, and by applying the concept also towards the material as well as the energy question, the project will show that it is possible to integrate the building sector in a functioning sustainable system already today. The city of today will be the resource for the city of tomorrow. It needs a new generation contract for both – the society and young architects, engineers and planners at large.

The impact of such a radical paradigm shift is not debatable. In the light of a world-wide climate crisis, we need to shift our way of how we think, design and construct architecture. RoofKIT will be a demonstrator for a new generation of buildings, that take their responsibility seriously. It will show that social sustainability in form of affordable high quality living space interacting with their neighbourhoods is a question of good and informed design, that solar harvesting will not be an accessory but a mandatory part of any design process and mobility concept and that resources coming from the urban mine and designed as a material bank can and will be interwoven to a synergetic resilient design as they are enabled to move unrestrictedly in a future circular economy.

KIT Material Library: impressions of the construction site

Work in the materials library is progressing. More and more parts of the old raw building fabric are becoming visible.

The renovation of the premises of the material library began some months ago and a lot has already happened. For example, current new electrical installations are being installed and a new modern lighting design has already been completed and will be implemented soon.

After many areas have been uncovered, a contemporary repair of the ceiling and walls is now taking place as well as the preparations for the new glazing.

The new material library will thus become a spacious, airy room, which will already provide generous views from the outside. We will continue to report on the development status of the new KIT material library here on the ChangeLab platform.

The renovation of the premises is supported by Wacker Chemie AG.

Das KIT braucht dringend neue Lernräume! Plätze in der Bibliothek sind gemessen an der Studierendenzahl rar und meist schnell ausgebucht. Auch Arbeitsplätze, vor allem Gruppenarbeitsplätze (2-6 Personen), sind Mangelware. Das AKK  (Arbeitskreis Kultur und Kommunikation) bietet nur bedingt die Möglichkeit im Sommer draußen zu lernen – es fehlt an einer entsprechenden Infrastruktur wie z.B. Steckdosen, Blend-, und Sonnenschutz und einem Dach bei Regen.

Deswegen soll im Rahmen eines Stegreifs des Fachgebiets Nachhaltiges Bauen gemeinsam mit dem Zukunftscampus KIT ein Prototyp entworfen werden, der Lernen und Arbeiten im Freien ermöglicht. Der Prototyp kann dabei beispielhaft auf einer Freifläche des KIT geplant werden, sollte aber einer möglichen Versetzbarkeit entsprechend mitgedacht werden.Ziel ist es mit Hilfe des „Outdoor Lern- und ArbeitsRAUMS“ gut gestaltete öffentliche und soziale Räume zu schaffen, und durch neue Landmarken eine Sichtbarkeit auf dem Campus zu etablieren. 

Der Stegreif ist als Wettbewerb ausgelegt und bietet Möglichkeiten zur Realisation.

Sorge um den Bestand. Ten strategies for architecture

The KIT professorship of Sustainable Construction at the Faculty of Architecture is part of an exhibition and publication by the Association of German Architects BDA. In ten strategies, architects and urbanists present their concern for the existing building: taking care of the building stock, for growing social structures and for the continued existence of the earth. They invite you to read the permanence of what has been built and what has grown and plead for further thinking and careful repair of living spaces and living cultures. They show how new perspectives arise in the urban and regional context through networked approaches, through cooperation oriented towards the common good and through participation concepts. For the future, i.e. the buildings erected today, strategies for the circular use of materials and an openness to future requirements are being developed.

The exhibition of the Association of German Architects BDA was curated by Olaf Bahner, Matthias Böttger and Laura Holzberg. Exhibition design: Marius Busch – ON / OFF and Christian Göthner – lfm2 “Sorge um den Bestand” is a project in the “Experimental Housing and Urban Development” research program of the BMI / BBSR and is financially supported by the Federal Ministry of the Interior, Building and Home Affairs.

deutschland.de: Two ideas that will take us forward

Construction with fungal roots and storing electricity with wood waste are two innovations that we will (hopefully) hear much more about in the future. At the Karlsruhe Institute of Technology (KIT) Professor Dirk E. Hebel is conducting research into radically different solutions. He wants to replace conventional building materials like concrete with renewable raw materials.

Design through and with material knowledge

An interview with the Dean of the KIT Faculty of Architecture Dirk E. Hebel and seminar leader Sandra Böhm of the Professorship of Sustainable Construction about their design strategies and the compatibility with materials science in architectural education.

The KIT Faculty of Architecture has a long tradition in understanding architectural design in close interaction with and in dependency on structural design, building construction, building physics, social studies and material science. The students deal critically and actively with the pressing questions of our times and are looking for ways to align their own actions with these findings.

The focus at the KIT Faculty of Architecture is on integrated design, so that conceptional, ecological, economical, structural, physical, sociological, historic, artistic, communicational, urban, landscape and theoretical questions are understood and treated as a holistic interdisciplinary project in the design itself. Thus, design studios serve as a field of experimentation and students are given the opportunity to show and test their ideas and conceptions in innovations and experimental studies.

This also includes the rediscovery of traditional materials and their possibilities in terms of the synergy of tradition and innovation. In the research seminar “Bau auf!” held together with the Karlsruhe Majolika, the students dealt with the material ceramic and the possibilities of 3D printing.

The innovation platform “Changelab! Wacker KIT Innovation Platform for Pioneering Sustainable Construction” builds a bridge to cooperation with the industry and is intended to bring together students, architects, engineers, and construction experts who are looking for new approaches in the field of material development and construction methods for a circular economy.

The power of mushrooms

Mushrooms are given little attention – but are they the secret rulers of the world? “PUR +” presenter Eric Mayer discovers new possibilities and also visits the KIT-MycoLab of Prof. Dirk E. Hebel and his research team around Dr. Nazanin Saeidi and Dr. Alireza Javadian to understand how a new class of building materials could be cultivated.

Rammed Earth Seminar – the Video

From technique to application: in a joint seminar of the KIT Professorships of Sustainable Construction and Building Technology, a small rammed earth garden house was being built near Freiburg. The seminar consisted of testing the material, building the suitable formwork, bringing the clay in and compacting it by manual work.

In addition the students received the basic and background knowledge in advance and had the possibility to learn about the geological local conditions afterwork on site.

This way they gained practical experience in this construction method under adapted conditions to obtain technical know-how and to experience the possibilities and the materiality of rammed earth on a building site.

Zukunft Bauen – Hat die Kreislaufwirtschaft auf dem Bau eine Chance?

Prof. Dirk E. Hebel in discussion about a rising circular building economy.

A talk in “Zukunft Bauen” with Prof. Dirk E. Hebel (Sustainable Construction, Faculty of Architecture, KIT Karlsruhe) and Dr. Lamia Messari-Becker (Building Technology and Building Physics, Institute of Architecture, University of Siegen) about rethinking the construction industry and its bound building materials as a raw materials warehouse in order to preserve the earth’s resources and about the paradigm change in future architectural planning and construction.

Design Studio Master: Insel der Lemuren

Ein neues Zuhause für die Affen im Karlsruher Zoo!

The endangered Kattas (lemures) of the Karlsruhe zoo live in a small enclosure in the monkey house at the moment, that no longer corresponds to the recommended guidelines. At the request of the zoo, the Ludwigsee island in the middle of the Stadtgarten is to be developed as a walk-in island and serve as a new home for the lemures. This will give them 20 times more space than is currently available to them. In order to keep this natural habitat as large as possible and not to take away any space on the island, the warm house will be built on the territory of the lake and serve as a refuge for the monkeys in cooler temperatures or bad weather.

The design is designed as an idea competition and offers possibilities for realization.

Innovative Wohnkonzepte für die Generation Gold

Jeden Tag wird in Deutschland die Fläche von etwa 100 Fußballfeldern in Bauland umgewandelt und damit versiegelt. Der Sachverständigenrat für Umweltfragen stellte unlängst fest, dass der Wohnungsbau einer der bedeutendsten Treiber dieser Entwicklung ist. Die durchschnittliche Wohnfläche pro Kopf ist auf inzwischen 46,7 m² (Stand 2018) angestiegen. Dazu kommt ein überhitzter Wohnungsmarkt in vielen Teilen des Landes. Insbesondere für junge Familien ist es häufig sehr schwierig stadtnah geeignete und ausreichend große Wohnungen finden. Die bisher oft einzige Antwort darauf, neue Baugebiete auszuweisen, fördert allerdings den weiteren zügellosen Flächenverbrauch in Deutschland. Doch auch innerhalb des Wohnungsbestands gibt es Flächenreserven. Eine besondere Rolle dabei spielen ältere Menschen. Nach Angaben des Bundesamtes für Bauwesen und Raumordnung belegte ein Ein-Personenhaushalt in der Altersgruppe über 75 Jahre im Jahr 1978 noch 55 m² Wohnfläche, im Jahr 2002 waren es bereits 75m², während die sich der durchschnittliche Wohnflächenverbrauch junger Ein-Personenhaushalte im gleichen Zeitraum fast nicht veränderte. Fast die Hälfte der Einpersonenhaushalte
in Deutschland werden von älteren Menschen bewohnt, und in einem Viertel aller Privathaushalte lebten 2018 ausschließlich ältere Menschen ab 65 Jahren. Der Wohnflächenverbrauch pro Kopf ist also nicht nur generell hoch, sondern auch sehr ungleich verteilt. Viele ältere Menschen der „Generation Gold“ sind nach dem Abschluss ihres Berufslebens nach wie vor aktiv und fit, aber dennoch oft mit dem Unterhalt ihrer meist zu groß gewordenen Haushalte überfordert. Was, wenn man den Wohnungsmarkt einfach, wie früher eine Festplatte, „defragmentieren“ könnte? Ist es möglich eine Win-Win-Situation für beide Seiten zu entwerfen?

In Kooperation mit der Nestbau AG Tübingen werden wir in Pfrondorf bei Tübingen innovative Wohnkonzepte entwickeln, die es für Personen der „Generation Gold“ attraktiv machen, ihre Wohnung zugunsten junger Familien aufzugeben, ohne auf ein selbstbestimmtes und aktives Leben in der gewohnten Nachbarschaft verzichten zu müssen. Gleichzeitig bietet sich dadurch ein Potential, die Wohnsituation des Einzelnen mit gemeinschaftlichen Räumlichkeiten und Treffpunkten aufzuwerten, die einen sozialen Austausch der Bewohner mit ihrem Umfeld befördern, und dadurch einen Mehrwert für die „Generation Gold“ bedeuten.

Wir werden den Entwurf in enger Zusammenarbeit und mit integrierten Vertiefungen von Tragkonstruktion (Prof. Pfeifer), Bauphysik und technischer Ausbau (Prof. Wagner) und Bauökonomie (Hon. Prof. Kai Fischer) durchführen.

Sortenrein Konstruieren

Circular Construction Methods

In a joint seminar, construction methods are to be investigated and documented that can guarantee the future deconstruction of buildings by type and thus form the basis of cycle-based construction. At the beginning the basics and principles of joining and designing a future recycling economy will be taught. Based on this topic, historical and current construction methods will be examined, which can be deconstructed, reused or recycled after their use in the building.

Appointment: Thursday, 10:00 – 11:30 Uhr

Number of Participants: 20

Seminar: Building the future!

A demonstrator for sustainable construction in cooperation with Wacker Chemie AG

Demonstrators in the building sector serve to place new vectors into the future and to generate potential fields. It is vital that innovations are encouraged that will help to reduce the environmental impact of building components as well as increase their durability, recyclability and sustainability.  In the vision of a future-orientated construction industry we have to find new solutions in developing and applying novel and sustainable construction materials and techniques. 

By developing a demonstrator for the future building industry, the students get the chance to develop scenarios for construction applications for a circular construction economy. Scenarios that adapt to new conditions and do not consume raw materials, but only use it and return it to its original state after the life cycle of the construction. 

After a research on existing demonstrators the students will collect materials and construction methods which fulfil specific criteria for a sustainable and circular economy. In a further phase of the seminar, the students will design the demonstrator and bring their research into practice.

Wacker Chemie, as the collaborator of this seminar will give the students the opportunity to realize their best design concepts.


In the Winter Semester 2020/21, the KIT Faculty of Architecture will offer a lecture series on Sustainable Construction, organized by the Professorship of Sustainable Construction, Dirk E. Hebel. In total 12 lectures will address the history, state of the art, and alternative futures within the theme. Speakers are: Daniela Schneider, Prof. Daniel Fuhrhop, Prof. Andreas Wagner, Prof. Matthias Pfeifer, Prof. Markus Neppl, and Prof. Dirk E. Hebel. Please refer to the poster for actual dates. The lecture is held every Wednesday, 10:00 am online.
