Circulate!

Circularity in Construction - Perspectives and Challenges
Circulate!

The one-day conference "Circulate!" addresses the circular economy in construction, its opportunities and challenges, and is the official conclusion of the program within the framework of the STO visiting professorships at KIT on the topic "Sustainable Materials for a new Architectural Practice - Entering a circular economy". The guest professors addressed the question of how, in times of climate change and an increasingly noticeable scarcity of resources, we can deal with our natural resources responsibly in building by means of single-variety design planning, a forward-looking approach to materials, and the idea of urban mining.

The conference provides a platform to discuss different perspectives on circular economy in construction from Belgium, the Netherlands, Switzerland and Germany. Three teams have taught design studios and seminars on this topic as part of the STO visiting professorships in the past semesters at the KIT Department of Architecture and discussed new topics in the field of a circular architecture practice with the students. Teaching was done by Maarten Gielen from RotorDC in Brussels in cooperation with Prof. Dr. Anupama Kund oo from Anupama Kundoo architects, Pune and Berlin. In addition, Kerstin Müller taught with Oliver Seidel of Zirkular / baubüro in situ, Basel, and Peter van Assche with Katja Hogenboom of bureau SLA, Amsterdam.

Guests from administration, politics and practice from the different countries and their frameworks on the topic of circular economy will expand the conference with contributions. What are the challenges of the circular economy with regard to planning law requirements in the construction industry and how can these be overcome? What are the practical and legal hurdles to the use of reused components and materials? And what steps would have to be taken to promptly introduce circular construction as a standard in practice, as required by the EU?

Prof. Dirk E. Hebel, Professor for Sustainable Building and Dean of the KIT Department of Architecture, will lead through the event.

About the Lecture
The transition towards a more regenerative construction practice requires not just technical innovations, but also a fundamental shift in the system logic on which architects and engineers rely. It is therefore not just an environmental, technical or economic project: it needs to be a cultural recalibration. Or, as some might say: a cultural revolution. To achieve a fundamental shift it is necessary to explore new modes of thinking. In recent years we have, with students, begun to explore radical design strategies that anticipate the world of tomorrow. These strategies contribute - each from their given perspective - to a building practice that is truly regenerative. In his talk, Peter van Assche will sketch the outlines of the regenerative cultural revolution, show the potential of design research in education,  and present some of the answers that the design projects have to offer.
About the Speaker:
After beginning his career in science and experimental mathematics, Peter van Assche transitioned into architecture and is now the founding principal of bureau SLA, an Amsterdam-based firm focused on the necessity of transitioning to a circular economy through design. As a design studio, bureau SLA consists of a team of architects and builders, supported by architectural historians, landscape architects, and energy experts. The studio does not wait for commissions to be given but builds and develops in the city in an innovative way — from their own initiatives and with their own manpower. By designing, researching, inventing, and building the full potential of material use, energy, waste flows, smart living & working and development processes are discovered - and realised.
 
Peter van Assche is professor Architecture and Circular Thinking at the Academy of Architecture Amsterdam, and supervisor for the Utrecht station area. He received a Master of Information Technology (cum laude) from the Technical University Eindhoven and obtained his architecture degree from the Rotterdam Academy of Architecture. He was visiting professor in Erfurt (2019), at Cornell University (2020, 2022), and at the Karlsruhe Institute of Technology (2022, 2023).

About the Lecture
The promises presented by a new building culture are significant. Through knowledge, research, innovation, and projects, the potential for creating architecture that supports a circular future is convincingly demonstrated. However, the implementation and scaling up of these practices in real-world applications is lagging behind, resulting in a limited number of circular buildings. As a practicing architect, it is difficult to implement these new practice within the existing system.  Additionally, it is crucial to support pioneers who possess the capability to build for the future. Marleen van Driel, an architect and head of the architecture program for Ammodo, is actively working towards driving a new building culture. In her talk, she provides valuable insights into the trade-offs involved in an ambitious architecture program that aims to highlight crucial projects and architects who prioritize respect for people, location, local climate, -materials, and history. This program aims to provide a larger platform for these architects and their projects.
About the Speaker
Marleen van Driel works as an architect focused on nature-based solutions and is head of architecture for the Ammodo Foundation, where she works on an ambitious architectural program that aims to stimulate location-specific, exemplary architecture with social and ecological responsibility across the globe.
She studied Architecture at the Delft University of Technology in the Netherlands and worked for 11 years on various complex projects at Benthem Crouwel Architects after graduation. She then worked as an Associate Architect Sustainability at the multidisciplinary design office Rijnboutt. Here, she contributed to the integral sustainability within the firm, both in strategy and (research) projects. She worked on the urban densification challenge Merwede in Utrecht, with the aim of improving the living environment for humans and nature.
In addition to her design work, she taught at the TU Delft in the Extreme Architecture design studio and participated in the editorial board for ‘The Green Architecture Guide of Amsterdam 2000-2025.

The 'economy' in circular economy
Maarten Gielen

Designer and Researcher | Co-founder of Rotor and Director of Rotor DC, Brussels

About the Lecture
Considering that it is today in West Europe significantly cheaper to waste most building materials compared to reusing them, it is clear that the circular economy many aspire to cannot be realised with technological and logistical innovation alone. The framework of our economy is hopelessly outdated, yet it continues to determine what circular practices are considered successful and what others are not. In his intervention, Maarten will show some of the perversities of the circular economy today, and suggests simple ways forward. Perhaps not the abolition of capitalism, but economic reform none the less.
About the Speaker
Maarten Gielen co-founded Rotor in 2006, a collaborative design practice with a particular interest in material flows. Maarten played a key role in most exhibitions and publications that Rotor produced before 2015 such as Deutschland Im Herbst (DE, 2008), Usus/Usures for the Belgian pavilion at the 2010 Venice Biennale (IT), Ex-Limbo for the Fondazione Prada in Milan (IT, 2011), OMA/Progress, on the work of OMA/Rem Koolhaas at the Barbican Art Gallery in London (UK, 2011), and Behind the Green Door for the 2013 Oslo Architecture Triennale (NO).
 
In 2014 he co-initiated Rotor Deconstruction, a company that trades in salvaged building materials. He acted as director of RotorDC till June 2023, growing the company to around 25 employees. For his contribution as an author, designer and projects initiator, Maarten received the Maaskant Prize for Young Architects. He occasionally teaches in various architecture & design schools including HEAD in Geneva, AA in London, the TU in Delft, Karlsruhe Institute of Technology, and Columbia University in New York.

Re-building Barcelona: Work in progress on a method for the reuse of building materials within the public sphere
Caterina Miralles Tagliabue

About the Lecture
Barcelona is a city with a strong historical relationship with its architecture and urban planning; from the Eixample project in 1860, the internal relocation of monuments in the Barrio Gòrico, to the renovation of the Olympic Village and the construction of the beach in 1992. Barcelona’s urban history is entangled with the various socio-political and economic changes which shaped, and shaped, the city's current urban landscape. Today, however, the city is facing new challenges - ones that respond to the growing uncertainty of Mediterranean climates and the need to re-visit an urban model historically divorced from non-linear narratives and environmental practices. The underlying slogan behind Barcelona City Council’s current planning model calls for “a plan that responds to the triple crisis we are going through; social, environmental and economic".
In order to adapt and build a resilient urban model which responds to contemporary values, Barcelona’s city hall has launched numerous projects aimed at strengthening the city's commitment to the UN’s Global Sustainable Development Goals; The Superillas (Super Blocks), Eixos Verds (Green Axis) and the project ReUsa (ReUse). Each project calls into question; How can one intervene in a city by building from what is already there? How can circular values be implemented from the remnants of capitalist systems? And what are the human values we must foster?  
In an attempt to unravel and expand upon these questions, Caterina Miralles will talk about the urbanism of Barcelona, and its future challenges, through the vector of her experience developing projects for material reuse and participatory design alongside Barcelona’s City Hall and research center La Escocesa. Highlighting the unique issues facing Barcelona as it attempts to address the intrinsic interrelations between its social, environmental, and political ecologies.
About the Speaker
Caterina Miralles is a young architect and multimedia artist. Holding an MA in architecture from the Architectural Association School of Architecture her practice moves between London and Barcelona.
Caterina has led investigation projects focusing on the use of extractive waste in England's quarries and is currently collaborating with the City Hall of Barcelona to generate a system for the reuse of building materials at a municipal scale.
Her work as a co-curator at the Fundació Enric Miralles was focused on her interest in Barcelona’s development through the implementation of divergent design methods, such as non-extractive architecture, and the reutilization of building materials.
Her artistic practice continues to develop via different media including her documentary films, as well as the research she is currently developing as a resident at the center of La Escocesa. Together with local design universities such as the European Institute of Design and the Eina School of Design, she leads teaching courses documenting occupational changes in the city and the implication of design, from object to city scale.
