Tropical coral reefs, one of the world’s oldest ecosystems which support some of the highest levels of biodiversity on the planet, are currently facing an unprecedented ecological crisis during this massive human-activity-induced period of extinction. Hence, tropical reefs symbolically stand for the destructive effects of human activities on nature [4], [5]. Artificial reefs are excellent examples of how architectural design can be combined with ecosystem regeneration [6], [7], [8]. However, to work at the interface between the artificial and the complex and temporal nature of natural systems presents a challenge, i.a. in respect to the B-rep modelling legacy of computational modelling.
The presented doctorate investigates strategies on how to apply digital practice to realise what is an essential bulwark to retain reefs in impossibly challenging times. Beyond the main question of integrating computational modelling and high precision monitoring strategies in artificial coral reef design, this doctorate explores techniques, methods, and linking frameworks to support future research and practice in ecology led design contexts.
Considering the many existing approaches for artificial coral reefs design, one finds they often fall short in precisely understanding the relationships between architectural and ecological aspects (e.g. how a surface design and material composition can foster coral larvae settlement, or structural three-dimensionality enhance biodiversity) and lack an integrated underwater (UW) monitoring process. Such a process is necessary in order to gather knowledge about the ecosystem and make it available for design, and to learn whether artificial structures contribute to reef regeneration or rather harm the coral reef ecosystem.
For the research, empirical experimental methods were applied: Algorithmic coral reef design, high precision UW monitoring, computational modelling and simulation, and validated through parallel real-world physical experimentation – two Artificial Reef Prototypes (ARPs) in Gili Trawangan, Indonesia (2012–today). Multiple discrete methods and sub techniques were developed in seventeen computational experiments and applied in a way in which many are cross valid and integrated in an overall framework that is offered as a significant contribution to the field. Other main contributions include the Ecosystem-aware design approach, Key Performance Indicators (KPIs) for coral reef design, algorithmic design and fabrication of Biorock cathodes, new high precision UW monitoring strategies, long-term real-world constructed experiments, new digital analysis methods and two new front-end web-based tools for reef design and monitoring reefs. The methodological framework is a finding of the research that has many technical components that were tested and combined in this way for the very first time.
In summary, the thesis responds to the urgency and relevance in preserving marine species in tropical reefs during this massive extinction period by offering a differentiated approach towards artificial coral reefs – demonstrating the feasibility of digitally designing such ‘living architecture’ according to multiple context and performance parameters. It also provides an in-depth critical discussion of computational design and architecture in the context of ecosystem regeneration and Planetary Thinking. In that respect, the thesis functions as both theoretical and practical background for computational design, ecology and marine conservation – not only to foster the design of artificial coral reefs technically but also to provide essential criteria and techniques for conceiving them.
Keywords: Artificial coral reefs, computational modelling, high precision underwater monitoring, ecology in design.
The goal of architecture is changing in response to the expanding role of cities, rapid urbanization, and transformation under changing economic, environmental, social, and demographic factors. As cities increased in the early modern era, overcrowding, urbanization, and pollution conditions led reformers to consider the future shape of the cities. One of the most critical topics in contemporary architecture is the subject of the future concepts of living. In most cases, domed cities, as a future concept of living, are rarely considered, and they are used chiefly as “utopian” visions in the discourse of future ways of living. This paper highlights the reviews of domed cities to deepen the understanding of the idea in practice, like its approach in terms of architecture. The main aim of this paper is to provide a broad overview for domed cities in the face of pollution as one of the main concerns in many European cities. As a result, the significance of the reviews of the existing projects is focused on their conceptual quality. This review will pave the way for further studies in terms of future developments in the realm of domed cities. In this paper, the city of Celje, one of the most polluted cities in Slovenia, is taken as a case study for considering the concept of Dome incorporated due to the lack of accessible literature on the topic. This review’s primary contribution is to allow architects to explore a broad spectrum of innovation by comparing today’s achievable statuses against the possibilities generated by domed cities. As a result of this study, the concept of living under the Dome remains to be developed in theory and practice. The current challenging climatic situation will accelerate the evolution of these concepts, resulting in the formation of new typologies, which are a requirement for humanity.
Ausgehend von der Bemerkung des Philosophen Jacques Derrida, dass Erbe immer auch eine Aufgabe sei, widmet sich der dritte Band der Schriftenreihe des Graduiertenkollegs „Identität und Erbe“ den sozialen und kulturellen Praktiken der Bezugnahme auf Vergangenheit(en) und Identität(en). Mit einem (kulturellen) Erbe soll und muss etwas getan werden, um es überhaupt hervorzubringen. Es konstituiert sich erst im Akt des (Nicht-)Erbens, das heißt im Wechselverhältnis mit den mit und an ihm ausgeführten Praktiken. Gleichwohl ermöglicht erst deren Verbindung mit den materiellen Überresten und Überlieferungen des Erbes eine Aneignung oder Ablehnung der Vergangenheit sowie die Fort- und Umschreibung eines bereits bestehenden Erbes. Diese Vorgänge sind nicht willkürlicher Natur: Die Möglichkeiten zur Interpretation und Deutung werden durch die sozialen, politischen, kulturellen, ökonomischen und technischen Bedingungen der Gegenwart sowie durch die Geschichte und Materialität des Erbes beschränkt, erweitert und gelenkt. Erbe und Erbeprozesse müssen deshalb notwendigerweise miteinander in Beziehung gesetzt werden.

Wer von Erbe im Zusammenhang mit Identität spricht, verspricht sich und Anderen »Kontinuität« und »Stabilität«. Das Versprechen hält indes nur so lange, wie sich Menschen auf die damit verbundenen Erzählungen einlassen. Da diese zunehmend hinterfragt werden und der Begriff »Identität« im politischen Raum zu einer umkämpften Kategorie avanciert ist, werden auch die lange gehegten, gewohnten »Konstruktionen« instabil. Dies zeigt sich insbesondere in Momenten des Konflikts, der übergriffigen Inanspruchnahme und des Verlusts. Der Titel »Instabile Konstruktionen« verweist zugleich auf die beiden Kernbereiche des Kollegs: einerseits auf Architektur und Denkmalpflege, in denen der Begriff Konstruktion sich auf bauliche Manifestationen bezieht, von denen eine gewisse Haltbarkeit und Dauerhaftigkeit erwartet wird und andererseits auf die Kultur- und Sozialwissenschaften, wo Konstruktion die soziale Herstellung symbolischer Sinnwelten meint. Ins Zentrum rückt so der Anspruch, die materielle Umwelt im Wechselverhältnis zu ihrer sozialen Gemachtheit zu verstehen.
