Load-responsive skin systems for lightweight architecture
No full textThis paper attempts at defining a novel method for designing integrated building skins taking inspiration from nature, where construction happens as an additive growth process with coherent development of form, structure and performance. The research focuses on the hierarchical structure of bones to challenge the current design paradigms of lightweight architecture. A skin system with highly specific material distribution has been conceived with the use of Additive Manufacturing to efficiently provide structural resistance. A method which encompasses computational design workflow, fabrication experiments and performative assessment of full-scale prototypes produced with Additive Manufacturing is described herein. Algorithms for topology optimization of freeform shapes are employed to determine the material organization as well as a performative matrix for the creation of a custom lattice microstructure defined as Functionally Graded Lattice Structures (FGLS), a system of load-responsive interconnected struts with spatially varying characteristics. Through experiments at different scales the viability of the hierarchical load-bearing envelope is demonstrated as a construction system for free-form lightweight constructions. In conclusion, it is discussed how bio-inspired design strategies contribute significantly to define role-models for catalyzing the potential offered by emerging fabrication technologies in architectur

Load-Responsive Cellular Envelopes with Additive Manufacturing
Get PDFThe last decades have been marked by a growing concern over scarcity of resources caused by the rapid industrialization of emerging economies as well as by the high material consumption at a global scale. These changing environmental conditions have inevitably created new challenges and demands for mediation of the interaction between the natural and the human-made environments. In response to these challenges, designers are currently moving away from conventional top-down design, towards a nature-inspired approach in search of the underlying principles of morphogenesis and materialization inherent to biological entities. Inscribed in this approach, this paper proposes an innovative design-to-fabrication workflow for the conception of nature-inspired load-responsive skin systems which integrates the use of computational tools, Additive Manufacturing, and material experiments with full-scale prototypes. The design phase employs custom algorithms to determine an optimal material distribution for free-form architectural shapes, given a specific loading condition. Through fabrication tests at different scales, the viability of a production system based on Fused Deposition Modelling is demonstrated. Subsequently, the realization of a final prototype of a load-responsive cellular envelope cladded with Fiber-Glass Reinforced Plastic is presented. Opportunities and current limitations of the approach and the emerging architectural system are critically discussed towards future developments
Robotic assembly for reversible timber construction
No full textLAUREA MAGISTRALEIl cambiamento climatico è una delle sfide più importanti della società contemporanea. Il mondo delle costruzione è largamente responsabile per le emissione di anidride carbonica nell'atmosfera che causano il riscaldamento globale. Aldilà di affermazioni simboliche, i progettisti di oggi sono chiamati a prendere coscienza di questo problema e concepire nuovi modi di progettare e realizzare edifici, al fine di salvare il pianeta e le generazioni future.
Per fronteggiare questa emergenza, serve approcciare in modo sinergico i vari elementi costitutivi dell’ambiente costruito. In questo spirito, la tesi guarda all’ecosistema contemporaneo di materiali e tecnologie innovative, combinando l'uso del più sostenibile materiale da costruzione, il legno, con i più recenti avanzamenti in automazione, attraverso l'applicazione dei robot collaborative e della progettazione computazionale.
Un nuovo approccio per un architettura in legno viene introdotta partendo dalla concettualizzazione di un processo per la manifattura stratificata di strutture, aiutata da bracci robotici intelligenti. L'obiettivo e’ avanzare la costruzione in legno tramite l'utilizzo di configurazioni tettoniche complesse informate da logiche di assemblaggio robotico, ottimizzazione materica e topologica, assieme al design combinatoriale. Con l'integrazione di un sistema di costruzione universale e l'interazione tra uomo e robot, le strutture architettoniche acquisiscono maggiore efficienza, reversibilità e capacità di aggiornarsi ed evolversi nel tempo.
Sviluppi in termini di tecnologia materiale e di fabbricazione, combinati a nuovi processi di progettazione e automazione sono applicati alla produzione di prototipi costruiti che dimostrano un approccio inedito, che contribuisce positivamente a ridurre la quantità di anidride carbonica nell'atmosfera ispirandosi a principi di economia circolare.Climate change is the most challenging emergency that our society is facing. The building industry, combining construction and operations, is largely responsible for emissions of carbon dioxide, which contribute significantly to global warming. Beyond symbolic statements, architects are required to transform the way our buildings are designed, constructed and used in order to save our planet and future generations.
To face this emergency and make a difference, we need to approach synergetically the multifold elements which constitute our built environments. In this spirit, the thesis looks at the current ecosystem of material and technology, combining the use of the most sustainable construction material, timber, with the most recent advancements in automation, by the use of collaborative robotics and computational design.
A novel approach to wood architecture is presented, starting from the conceptualization of a new process for robotic layered manufacturing. The aim is advancing construction through complex tectonic configurations which are informed by logics of robotic assembly, topology and material optimization, and combinatorial design. With the integration of a universal construction kit and human-robot interaction, structures gain higher efficiency, reversibility and capacity to update and evolve their configuration in time.
Developments in material and fabrication technology, as well as a new design and assembly process, are applied into the production of construction prototypes, which demonstrate a carbon-negative approach to architecture inspired by principles of a circular economy
Institutionalizing ASEAN: celebrating Europe through network governance
No full textThis article provides a new piece for two of the puzzles of institutionalized cooperation in Association of Southeast Asian Nations (ASEAN). First, with regard to the organization's four decades of existence, there has always been a marked gap between ASEAN's rhetorical goals of cooperation and its actual achievements. What explains these systematic failures of implementation? Second, from the outset, ASEAN was criticized for its light institutionalization, which failed to deliver the substantial cooperation goals. Despite selected institutional reforms, ASEAN's autonomy has not increased remarkably and it has not made any major institutional innovations. Why does ASEAN design institutions it does not use? Why does this transformation gap occur? The author suggests a sociological institutional explanation and argues that major impulses for cooperation have come from outside Southeast Asia, most importantly from Europe. By mimicking the European integration process, ASEAN member states have effectively created an isomorphic organization. The Association's institutional development reflects a concern for international legitimacy and less an objective functional demand arising from the specific interactions of member states. This copying process has led to network governance within the organization

Design and Additive Manufacturing of Lattice-based Cellular Solids at Building Scale
No full textThe amounts of material that is being extracted, harvested and consumed in the last decades is increasing tremendously and bringing to the serious problem of resource scarcity. As a direct consequence to this claim, designers are challenged to rethink architecture and develop new ways of confronting with materials. A potential answer to this problem is the exploration of computational logics for architectural design and fabrication inspired by the observation of biological formations. This work explores how the biological model of bone microstructure can be applied to a larger scale architecture that is structurally responsive, by means of computational design and Additive Manufacturing.Functionally Graded Trabecular Tectonics, Digital fabrication, Additive Manufacturing, Computational Design, Biomimetics <br/
