Design Studio Master: maKITlab!

A new digital workshop for the KIT Faculty of Architecture

The Faculty of Architecture at KIT urgently needs a new digital workshop. Funds are being made available by KIT for this purpose in order to go into realisation following the semester.

The semester task is to further design, plan and realise a circular replacement building as a digital experimental workshop between the buildings 11.40 and 20.40. The aim is to build a new digital workshop. At the end of the semester, a first building block is to be presented as a real-built mockup with the help of digital tools.

The aim is to provide students with a creative and functional space for digital mockup construction, offering sufficient space for cutting plotters, laser cutters and 3D printers.

The design will be published by the Sustainable Building Professorship together with the Digital Design and Fabrication (DDF) Professorship and the Design of Structures (dos) Professorship. In addition, a professional planning team consisting of the building owner and specialist planners will support the design with their expertise.

Prof. Dirk Hebel, Manuel Rausch, Katharina Blümke, Prof. Riccardo La Magna, David Largueche, Prof. Moritz Dörstelmann

First meeting: 20.04.23
Regular date: Thursday, 10:00 a.m., Building 11.40, R 26
Number of participants: 15 + 3 Erasmus (group work)

Seminar Master: Future-oriented Building Materials

A Research Seminar of the KIT Material Library

The Materials Library of the Faculty of Architecture at KIT, which is currently being reorganised as part of the “Materialbibliothek Deutscher Hochschulen” cooperation, offers an extensive collection of materials that, in addition to conventional building materials, focuses on building materials made from secondary raw materials, alternative biotic raw materials and recyclable building materials.

As a pioneer of sustainable building, this special group of materials makes it possible for future generations of architects to understand the value of purity, the necessity of using secondary materials and the preservation of value in the case of reuse or recycling.

In the research seminar Future-oriented Building Materials, Master’s students gain a detailed insight into this class of novel, endlessly circulating building materials. The seminar is accompanied by individual supervision, joint discussion rounds on specific topics, input lectures and excursions. However, the focus is on the students’ independent scientific research work, which aims to provide detailed descriptions of the materials. In this context, the students can work on the new KIT material database and enter data directly. In this way, the students are actively involved in building up the database. The seminar will conclude with an exhibition in the materials library. On display will be the data sets created by the students with the corresponding material samples of innovative, sustainable materials for the construction industry.

First Meeting: 25.04.23
Regular date: Tuesday, 10:00 a.m., Building 11.40, R 26
Excursion: 16.05.23 (more planned)
Participants: 12 master students

Seminar Week: Hand & Material

A round trip among traditional and future building 

In the seminar week we want to take a round trip between traditional and future building methods and explore the connections of hand and material.

We want to look at new manufacturing techniques in craftsmanship and technology, their interdependencies and dare a look into the future of construction towards digital fabrication. The journey will take us from Karlsruhe, via Stuttgart to the alpine foothills and then via Zurich and Laufen back to Baden. 

Some of the costs will have to be covered by the students themselves. We are striving to keep this part as low as possible.

arte 42: Are we being ruled by mushrooms?

This question is explored in an episode of “42-Die Antwort auf fast alles” produced by Hessischer Rundfunk.

The director writes: Fungi have hardly been researched. Yet they are among the oldest and most diverse forms of life on our planet. Only through fungi could plants develop ages ago. They are at home everywhere: in the earth, in the air, in our bodies. And they form huge networks. They are intelligent, although they do not have a brain of their own. They make decisions and trade with the plants they live with. They take possession of insect bodies and turn them into zombies. Are fungi the secret rulers of the planet? (text: HR)

Nazanin Saeidi in “42 – Die Antwort auf fast alles” © Hessischer Rundfunk

In this context, not only Dr. Nazanin Saeidi from the Sustainable Construction professorship is interviewed, but also the biologist Merlin Sheldrake, Francois Buscot from the Helmholtz Centre for Environmental Research in Leipzig and the political scientist Astrid Séville are invited to talk on the program.

NEWood awarded with competitionline CAMPUS Award 2023

© KIT Professorship Sustainable Construction

165 projects from 54 universities took part in this year’s competitionline CAMPUS Award. The spectrum of topics ranged from utopias for urban development and material studies to adaptive architecture and after-use strategies. The proportion of projects dealing with sustainable design tasks such as the conversion of existing buildings, climate adaptation in cities or research into alternative materials was particularly high.

In addition to two student award-winning projects, which went to the TU Munich and Leibniz Universität Hannover, and two award-winning final theses from the Kunstakademie Düsseldorf and the University of Stuttgart, one faculty project also received an award.

From nine projects submitted, the jury selected the work “NEWood, a 100% bio-based, sustainable and recyclable material alternative to wood-based products” as the winner. The research by the Institute of Design and Construction Technology at the Karlsruhe Institute of Technology resulted in the “development of a new class of bio-based, resource-efficient and CO2-negative materials.” As an alternative to particleboard, MDF and OSB, the boards are made exclusively from wood and agricultural waste. Mushroom mycelium is used as a natural binder, so no synthetic binders are required.

The research project shows that NEWood has comparable properties to wood-based materials such as MDF, OSB and particleboard. The use of mycelium, the structural part of fungi, is a novel bonding method that enables the production of a 100% bio-based and fully recyclable alternative to wood-based materials. The project team, consisting of Dr. Alireza Javadian, Dr. Nazanin Saeidi and Prof. Dirk E. Hebel, is convinced that “NEWood” will be a sustainable alternative to conventional MDF and particleboard and has the potential to initiate a paradigm shift in the way we produce our future building materials in terms of the circular economy without leaving any waste behind.

Learn where you want

This pavilion at KIT (Karlsruhe Institute of Technology) shows with sustainable construction how learning and lingering on campus can look like. The project emerged from the impromptu of the Professorship of Sustainable Construction “Learn where you want” in the winter semester 2020/21.

With this interdisciplinary pilot project, students have ventured a step into the future of university life together with the Professorships of Sustainable Construction (IEB) and Construction Technology (IEB), the Sustainability Office (SEK), the Technology House (TEC), and the Real Estate Management (IM) of the KIT. The sustainable development of the university campus is focused on increasing the quality of staying and creating informal learning places. The overall motto is the creation of a “marketplace of knowledge”.

Local products, reversible joining methods and elements from the urban mine contribute to circular construction with a mono-material design.

Open to appropriation, the pavilion offers several levels at different heights for sitting, lingering and learning. The structural framework develops windmill-like from a multifunctional core element to the outside and gives the learning place its distinctive identity. The open structure encourages exchange and allows interaction with the surrounding green spaces.

WDR planet wissen: The battle for sand

© planet wissen, WDR

Sand is one of the most sought-after raw materials in the world. The global demand for sand is gigantic and has tripled in the past 20 years. Sand is in the concrete of booming megacities around the world and is important in coastal protection. How do we have to build so that cities can continue to grow in the future?

This and many other questions are addressed in the current edition of Planet Wissen, “The battle for sand – new ways of dealing with the coveted raw material. In the second half of the episode, Prof. Dirk E. Hebel from KIT is a guest in the studio with the moderator Jo Hiller and reports on recycling-friendly construction, single-variety, degradable construction, and alternative building materials such as bamboo or mycelium.

Helmholtz: How we build in the future

In the article “How we build in the future”, the Helmholtz Association presents sustainable, climate-friendly solutions from architecture and construction research. In this context, Prof. Dirk E. Hebel presents the RoofKIT project of the KIT Faculty of Architecture as an innovative lighthouse project for circular justice, purity of types, recycling and reuse, and the resource-friendly handling of materials.

Concrete as a building material is then critically examined. Prof. Frank Dehn, Institute Director at the KIT Civil Engineering Faculty, is researching climate-friendly alternatives and the use of old concrete. In addition, other forward-looking topics such as the “sponge city” and the energy supply of future buildings are highlighted.

Prof. Dirk E. Hebel speaks at the Parliamentary Evening at the Deutsche Bundestag Berlin

Climate change is becoming a particular challenge for our urban life: our cities heat up particularly strongly in summer, and extreme weather such as heavy rainfall pushes infrastructure to its limits. Worldwide, almost 60 percent of people live in urbanized settlements, and the number is steadily increasing. As global temperatures continue to rise, so do the challenges facing cities and the people who live in them. In Berlin on November 8th 2022, several scientists talked and elaborated on the question of how to design and adapt our cities for such challenges ahead. The parliamentary evening was organizezed by Helmholtz SynCom.

RoofKIT: Welcome to Karlsruhe!

RoofKIT, the Karlsruhe winning project of the Solar Decathlon 2021/22 was re-located and re-errected in Karlsruhe on Wednesday 09 November 2022. Under the supervision of the project management, the wooden modules were dismantled in Wuppertal within two days, transported to Karlsruhe and now reassembled by the experienced carpenters of Kaufmann Zimmerei und Tischlerei in cooperation with the KIT Solar Decathlon team.

About the project:
The Karlsruhe Institute of Technology participated in the 2021/22 Solar Decathlon Competition in Wuppertal, Germany with its project RoofKIT. Designed as a top-up to an existing structure, it demonstrates a vision for the building industry: social adequate, energy positive and circular sustainable. Since 2020, more than 100 students from KIT within different faculties and under the leadership of the professorships of Sustainable Construction (Prof. Dirk E. Hebel) and Building Technologies (Prof. Andreas Wagner) worked on the project which cumulated in the construction of the House Demonstration Unit in May and June 2022 in Wuppertal, Germany.

Prof. Dirk E. Hebel meets Kassem Taher Saleh, Member of the German Bundestag in Berlin

On Monday, 7 November, Dirk E. Hebel was invited to the Bundestag by Kassem Taher Saleh, Member of the German Parliament and Chairman of the Committee on Housing, Urban Development, Construction and Municipalities, to discuss which recommendations for political action can be derived from Dirk E. Hebel’s research. Mr Saleh, a civil engineer by profession and member of Bündnis 90/Die Grünen, was particularly interested in wood as a building material along the entire value chain (raw material availability and end-of-life scenarios) and strategies for a truely circular economy in the building sector.

Expert discussion on “Innovative and sustainable building materials” of the Green parliamentary group in the state parliament of Baden-Württemberg in Stuttgart

At the expert discussion on “Innovative and Sustainable Building Materials” of the Green parliamentary group in the state parliament, to which Gudula Achterberg, member of the Heilbronn state parliament and member of the working group and committee on state development and housing, had invited on 21st October, science and practice met and identified future tasks for building and housing.

The speakers from science and research as well as from construction practice were united by the realisation that the current crises and global interdependencies can also accelerate developments in construction.

Keynote speaker Professor Werner Sobek received the Order of Merit of the Federal Republic of Germany in May as a thought leader for the built environment of tomorrow. The multi-award-winning engineer and architect insists on honest balancing when it comes to innovative and sustainable building materials: when it comes to the consumption of resources, be it sand, gravel, fossil fuels or precious metals. One of the other speakers advocated, for example, the introduction of a building type E for “experimental” for lighthouse projects, for which simplified standards apply in order to facilitate innovation. Dr Anne Braune from the German Sustainable Building Council (DGNB) advocated the use of pure, sustainable building materials and suggested as a parameter for approval: My building should emit a certain amount of CO 2 per square metre per year. She advocated looking “in the package insert” for building materials and for service life-adapted construction.

Dr Nazanin Saeidi, a researcher at the KIT Sustainable Building Professorship, presented an example of innovative building materials. Based on fungi, the award-winning material NeWood is suitable as a substitute for pressboard or for insulation. It is made from 100 per cent organic waste and is recyclable.

The event showed many developments that can and must revolutionise the way we build in the future. Nevertheless, the familiar and the tried and tested can help to overcome upcoming challenges in the construction industry.

Exhibition “Plastic: Remaking Our World” now at V&A Dundee in Scotland

The exhibition Plastic: Remaking Our World, which was initially on show at the Vitra Design Museum, will be on display at the V&A Dundee in Scotland from 29 October 2022. The contribution of the Sustainable Building Professorship will also travel from Weil am Rhein to Dundee.

Plastic: Remaking Our World will again feature prototypes, new technologies, and cutting-edge materials as designers grapple with a material that has changed our world. 

The exhibition will feature product design, graphics, architecture and fashion from the collections of the V&A and Vitra Design Museum, as well as collections all over the world. This is the first exhibition produced and curated by V&A Dundee, the Vitra Design Museum and maat, Lisbon, with curators from V&A South Kensington.

Building Better – Less – Different: Circular Construction and Circular Economy

Published in October 2022, edited by Dirk E. Hebel, Felix Heisel with Ken Webster

Cover © Birkhäuser Verlag GmbH, Basel 2022

Sustainability is to become the guiding principle of social action and economic activity. At the same time, its ways and means are far from clear. As a holistic praxis, sustainability must combine technical and material as well as social, economic, ecological and also ethical strategies, which have multiple complex interactions and all too often also conflicting goals and priorities. In no other field can these be better observed, addressed and influenced than in architecture and building.

Each volume of “Building Better – Less – Different” details two fundamental areas of sustainability and explores their specific dynamics and interactions. After introductory overviews, innovative methods and current developments are described and analysed in in-depth essays, international case studies and pointed commentaries. The sustainability criteria of efficiency (“better’”), sufficiency (“less”‘) and consistency (‘different”) form the framework for each book.

The first volume “CIRCULAR BUILDING AND CIRCULAR ECONOMY” presents concepts, methods and examples of circularity in construction and the economy. Urban mining and circular construction are two approaches to the changes that architecture and urban design are facing, using techniques such as mono-material construction and design for disassembly, and tools such as material passports and databases. The circular economy is not solely about recycling but encompasses a wide range of strategies from local community projects to new ownership and service models and steering mechanisms such as carbon fees and dividends.

MycoTree in the Natural History Museum in Karlsruhe

As part of the 17th “Karlsruher Frischpilzausstellung” of the Natural History Museum in Karlsruhe, the MycoTree was exhibited in the pavilion in the Nymphengarten on the 8th and 9th October. The exhibition displayed 250-300 species of mushrooms and presented various literature on mushrooms. The weekend exhibition was visited by almost 1300 people interested in mushrooms.

The MycoTree, a spatial structure made of the cultivated materials mushroom mycelium and bamboo, supplemented the exhibition with the topic area ‘Building materials from natural resources’. At 2 p.m. on both days, Sandra Böhm and Elena Boerman gave a short lecture on the exhibited project, which was created in 2017 as a cooperation project between the KIT Sustainable Building Professorship and the Block Research Group of ETH Zurich.

The assembled elements of the MycoTree can be disassembled again into their original materials and returned to the natural cycle as nutrients. In this way, it shows how digital design, technology and resource-saving materials could come together in the building industry in the future.

Design Studio Bachelor: Circular City: Heidelberg

Resource-efficient housing concepts for a growing city

Cities play a crucial role in the struggle for a sustainable and climate-friendly future. This is where housing, production, trade, transport and energy consumption all come together. In addition, our cities are gigantic stores of raw materials. In some areas, the resources tied up in the current building stock have long since exceeded the raw material deposits that can be reached with reasonable effort in the earth’s crust. This urban mine needs to be tapped.

The city of Heidelberg has set itself ambitious sustainability goals and wants to lead the way as a pioneer of the circular economy in urban development and urban planning. To this end, among other things, the project “Circular City – Building Material Cadastre for the City of Heidelberg” was launched, with which the city is relying on the urban mining principle. The building stock is being successively recorded and analyzed so that the data obtained can be made available to planners.

This semester, we will investigate how the application of circular building production and the use of materials from urban mining can succeed architecturally, using different design locations in Heidelberg. 

The design will take place in collaboration with the integrated disciplines of structural engineering (Prof. Riccardo La Magna), FBTA (Prof. Andreas Wagner), and building economics (Hon. Prof. Kai Fischer).

A laboratory for future building

The Faculty of Architecture and the Department IV Natural and Built Environment of KIT have set themselves the goal to become a pioneer of circular and sustainable building in Germany and Europe. This requires a new research, teaching and experimental laboratory for future building, in which research, teaching and practical applications can be interlinked and practiced. 

Topics of sustainable building should not only be researched, but the building should already show and demonstrate them. The laboratory is to become a showcase for research into future building for the entire society and an attractor for the city of Karlsruhe.

The semester task is to develop a construction laboratory located in area 10 on the south campus. An urban planning study is part of the task. A large ground-level hall is required, in which new possibilities for future construction will be researched with the help of digital manufacturing processes and robotics, and experimental buildings will be erected. Above the hall, teaching and learning spaces for students and researchers are to be created with common zones for exchange and networking.  On the roof area, individual research and innovation modules are to be installed according to the “plug-in” principle and can be dismantled again simply and easily. People will live and work in these changing units, so that they serve as busy experimental laboratories and at the same time shape and constantly change the appearance of the building.

Day and time: Thursdays, 9:00
1st meeting: 27.10.2022
Excursion to Zurich on 04.11.2022

Seminar: Circular component analysis

The deconstruction friendliness of a construction and the reusability of materials are decisive parameters for circular planning and building. For high-quality recycling and reuse of materials, material layers as well as components must be planned and installed in a detachable way. The aim of the seminar is to determine the qualitative material value of a separated component and to present it graphically, as well as to find new joining techniques. From the analysis, conclusions are to be drawn for the planning of new circular component constructions as well as to show ways for the design of alternative joining techniques. The analysis of the components is planned in a group work of two persons each.

Day and Time: Wednesdays, 13.30 – 15.00
First meeting: 26.10.22

Among the start-ups, the jury chose mygreentop. The “Innovation” category was won by Home Power Solutions with picea. The audience award went to the research project “Kalkspeicher” from the German Aerospace Centre (DLR). A total of more than 100 projects and companies entered the DGNB Sustainability Challenge this year.

The selection of the award winners in the DGNB Sustainability Challenge was different this year than in the past. In addition to the finalists, the eleven-member jury also directly determined the winners in the categories “Innovation”, “Start-up” and “Research”.

“The decision was enormously difficult for us as a jury,” says Dr. Christine Lemaitre, Executive Director of the DGNB and part of the selection committee. “All the finalists presented themselves excellently, which is why I can only congratulate them all. They are the best proof that there are smart, forward-thinking people in our industry who can combine sustainability with innovation.”

NEWood exhibition table © Professorship of Sustainable Construction

The “NEWood” project is a novel class of bio-based, resource-efficient and CO2-negative materials based on mycelium. Since NEWood shows comparable properties to MDF and chipboard, it serves as a substitute for wood and wood-based materials. The wood alternative is developed exclusively from available organic waste, including wood and agricultural waste, and is manufactured using fungal mycelium as a natural binder.

This year, the jury was made up of Dr Anna Braune (DGNB), Gerhard Breitschaft (Deutsches Institut für Bautechnik), Dominik Campanella (Concular), Prof. Moritz Fleischmann (Düsseldorf University of Applied Sciences), Prof. Andrea Klinge (ZRS Architekten), Dr Christine Lemaitre (DGNB), Martin Prösler (Proesler Kommunikation), Martin Rodeck (EDGE Technologies), Prof. Dr.-Ing.

Ausbau – Stegreif: Konrad Kocher Schule Ditzingen

08.07. / 09.07. / 11.07. / 23.07.
Termine jeweils von 8 – 19 Uhr

Rückfragen und Anmeldung an jonas.laeufer@kit.edu

Im Juli 2022 steht der Abriss des Hauptschulgebäudes der Konrad Kocher Schule in Ditzingen an. Ein ganz normaler Prozess im heutigen Baugeschehen. Die Stadt hat entschieden, die Schule entspricht nicht mehr den heutigen Ansprüchen, ein Wettbewerb für den Neubau einer Schule wurde ausgelobt, der Gewinner hat den Auftrag für das Projekt bekommen.

Viele Tonnen Baustoffe werden durch diese Entscheidung freigesetzt und nach dem üblichen Vorgang auf die Deponie befördert, recycelt oder thermisch verwertet. Vor zwei Wochen kam die Zusage der Stadt und des beauftragten Abbruchunternehmens, dass Material ausgebaut werden darf – der Abriss steht in vier Wochen an.

Ganz nach dem Motto „viele Hände, schnelles Ende“ wollen wir zusammen so viele Materialien wie möglich direkt oder indirekt „retten“ und so einen eigenen kleinen Beitrag zur Zirkulariserung leisten.

Als freies Kollektiv für zirkuläres Bauen ruft der Baukreisel gemeinsam mit dem Lehrstuhl für Nachhaltiges Bauen am KIT einen Ausbau Stegreif aus, um zusammen mit Studierenden die Linearität zu brechen und im Sinn der Kreislaufwirtschaft zu handeln. Hierbei geht es um das Katalogisieren und den Abbau der Materialien vor Ort, aber auch um die Planung, Logistik und Wiederverwendung der Materialien. Konkret sollen Materialien sowohl zur Wiederverwendung im Bau vorbereitet werden (Beispiel: Böden, Waschbecken, Armaturen) als auch für einen neue Nutzungsart aufbereitet werden (Beispiel: aus Türen entstehen Möbel). So wird neben der handwerklichen Abbauerfahrung auch die wirtschaftliche und gestalterische Komponente der Zirkularität beleuchtet.

Der Ausbau Stegreif wird an zwei Wochenenden in der ehemaligen Hauptschule in Ditzingen stattfinden. Ziel des Stegreifs ist es das Ausbauen und Katalogisieren von obsoleten Baumaterialen zu erproben. Das geborgene Material wird anschließend gelagert und soll im Herbst für eine Möbelserie und weitere Objekte verwendet werden.

Die Entwürfe können voraussichtlich in einem weiteren Stegreif erarbeitet werden.

Regina Gebauer – project leader RoofKIT – wins the TECU Architecture Award 2022

The TECU® ARCHITECTURE AWARD 2022 once again honours outstanding projects that make exemplary and innovative use of the extensive application possibilities of the TECU® brand. The overall architectural concept and the considered use of the material are decisive. The competition includes the category ‘Realised Buildings’ and ‘Project award for students’.

Regina Gebauer, meanwhile teaching and research assistant at the Professorship of Sustainable Construction, won the 1st project prize for students with her design project “Until everything moves”. In this project, she proposes the addition of two residential storeys to the existing Café ADA in the Mirker Quarter in Wuppertal, which was part of the Solar Decathlon teaching achievements over the past two years at the KIT Faculty of Architecture. The award ceremony took place on 17 June at the Solar Decathlon Europe in Wuppertal.
