title	Reconfigurable Formwork System for Vision-Informed Conformal Robotic 3D Printing

summary	Robotic additive manufacturing has garnered significant research and development interest due to its transformative potential in architecture, engineering, and construction as a cost-effective, material-efficient, and energy-saving fabrication method. However, despite its potential, conventional approaches heavily depend on meticulously optimized work environments, as robotic arms possess limited information regarding their immediate surroundings (Bechthold, 2010; Bechthold & King, 2013). Furthermore, such approaches are often restricted to planar build surfaces and slicing algorithms due to computational and physical practicality, which consequently limits the feasibility of robotic solutions in scenarios involving complex geometries and materials. Building on previous work (Çapunaman et al., 2022), this research investigates conformal 3D printing of clay using a 6 degrees-of-freedom robot arm and a vision-based sensing framework on parametrically reconfigurable tensile hyperbolic paraboloid (hypar) formwork. In this paper, we present the implementation details of the formwork system, share findings from preliminary testing of the proposed workflow, and demonstrate application feasibility through a design exercise that aims to fabricate unique components for a poly-hypar surface structure. The formwork system also offers parametric control over generating complex, non-planar tensile surfaces to be printed on. Within the scope of this workflow, the vision-based sensing framework is employed to generate a digital twin informing iterative tuning of the formwork geometry and conformal toolpath planning on scanned geometries. Additionally, we utilized the augmented fabrication framework to observe and analyze deformations in the printed clay body that occurs during air drying. The proposed workflow, in conjunction with the vision-based sensing framework and the reconfigurable formwork, aims to minimize time and material waste in custom formwork fabrication and printing support materials for complex geometric panels and shell structures.

title	Tree-Structure Canopy:A Case Study in Design and Fabrication of Complex Steel Structures using Digital Tools
source	International Journal of Architectural Computing vol. 11 - no. 1, 87-104
summary	This paper describes and reflects on the design and manufacturing process of the Tree-Structure canopy for the WestendGate Tower in Frankfurt upon Main, completed early 2011.The project investigated fabrication and assembly principles of complex steel structures as well as the integration of contemporary computational design, engineering, optimization and simulation techniques in a collaborative design approach. This paper focuses on the notion of modular standardization as opposed to non standard customized components. It also engages with issues relating to digital production tools and their impact on construction cost, material performance and tolerances. In addition it examines the reconfiguration of liability during a planning and construction process, an aspect which can be strongly determined by fabrication companies rather than the architect or designer.This paper is written as a reflection on the complete building process when contemporary digital tools are used from design through to fabrication. It studies both the generation of the steel structure as well the ETFE cushion skin. It reports on a collaborative project, where the main author was responsible for the canopies design, parameterization, digitalization and fabrication, as well as for the dissemination of the outcomes and findings during the design and realization process.As such it represents an example of research through design in a contemporary and evolving field.The canopy received a design award by the Hellenic Architecture Association.

title	Some Notes on the Incompleteness Theorem and Shape Grammars
source	Global Design and Local Materialization[Proceedings of the 15th International Conference on Computer Aided Architectural Design Futures / ISBN 978-3-642-38973-3] Shanghai, China, July 3-5, 2013, pp. 368-376.
summary	The paper presents a critique of the Shape Grammar paradigm viewed through the lens of the incompleteness theorem of Gödel. Shape Grammars have been extensively researched through many lenses. Their productive systemic nature was the focus of the first papers along with more recent treatises in the field while their use in analysis of known building styles has been extensive and a proven mechanism for style analysis. It is surprising though that use of Shape Grammars in actual design in practice however has been minimal. The architectural community has not actively used the paradigm in the design of real buildings, probably because of the rigid analytical approach to style and rules, following from the academic analysis that the paradigm has been subjected to. However I propose that there is another underlying reason, other than the rigid approach to construct a Shape Grammar. The nature of the concurrent application and creation of the rules lies close to the incompleteness theorem of Gödel, that uses a multitude of Turing Machines to prove that a from a set of True Axioms -A- we will never be able to determine if all sentences are true, without having to invent new axioms, outside the initial set -A-, thus unproven in terms of their true or false nature. Negation of this possibility drives us to the conclusion that true Design can never be feature -complete and thus can never be placed in a trusted framework that we all agree or believe it to be the complete truth.

summary	Architecture, nowadays, is an even more demanding activity in which complexity is the keyword: complex forms, complex functions and complex structures require sophisticated facilities and components, for example, ‘The Cloud’ of D. and M. Fuksas in Rome. These complexities can give rise to numerous risks, among which fire is frequently a central problem. The fire safety norms do not involve an approach integrated with other instruments or building model (BIM), but provide a list of information and constraints. These codes are now shifting away from a prescriptive-based towards a performance-based method due to recent progress in fire safety engineering. Following this approach, a case study simulation of a multi-purpose centre was carried out in Tivoli, near Rome. This simulation allowed greater freedom in architectural composition, a lower risk to people, a larger number of material and building components used and higher safety standards to be achieved. The model is based on the FDS (Fire Dynamics Simulator) language, a simulation code for low-speed flows, focused on smoke, particle and heat transport by fire.

summary	In the course of the 20th century, architectural construction has gone through intense innovation in its material, engineering and design, radically transforming the way buildings were and are conceived. Technological and industrial advances enabled and challenged architects, engineers and constructors to build increasingly complex architectural structures from concrete. Computer-Aided Design and Manufacturing (CAD/CAM) techniques have, more recently, rejuvenated and increased the possibilities of realising ever more complex geometries. Reinforced concrete is often chosen for such structures since almost any shape can be achieve when poured into a formwork. However, designs generated with digital tools tend to have limited relation to the efficient modes of production typically used in contemporary concrete construction. A large gap has emerged between the technology in architectural design and the building industry, so that few efficient solutions exist for the production of geometrically complex structures in concrete. This paper focuses on the capabilities and efficiency of existing casting techniques both with static and dynamic formwork which, when combined with digital fabrication, allow innovative fabrication approaches to be taken. Particular focus is placed on slipforming, an approved and efficient construction technique, which until now is unexplored in conjunction with digital fabrication.

title	Resilient Structures Through Machine Learning And Evolution
doi	https://doi.org/10.52842/conf.acadia.2013.319
source	ACADIA 13: Adaptive Architecture [Proceedings of the 33rd Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-1-926724-22-5] Cambridge 24-26 October, 2013), pp. 319-326
summary	In the context of the growing usefulness of computation within architecture, structures face the potential for being conceived of as intelligent entities capable of resilient, adaptive behavior.Building on this idea, this work explores the use of machine learning for structures that may learn to autonomously “stand up”. The hypothesis is that a neural network with genetically optimized weights would be capable of teaching lightweight, flexible, and unanchored structures to self-rectify after falling, through their interactions with their environment. The experiment devises a physical and a simulated prototype. The machine-learning algorithm is implemented on the virtual model in a three-dimensional physics environment, and a solution emerges after a number of tests. The learned behavior is transferred to the physical prototype to test its performance in reality. This method succeeds in allowing the physical prototype to stand up. The findings of this process may have useful implications for developing embodied dynamic structures that are enabled with adaptive behavior.

summary	Traditionally, interactivity in architecture has been suppressed by its materiality. Building structures that can transform and change themselves have been the dream of many architects for centuries. With the continuous advancements in technology and the paradigm shift from mechanics to electronics, this dream is becoming reality. Today, it is possible to have building facades that can visually animate themselves, change their appearance, or even interact with their surroundings. In this paper, we introduce Architectural Chameleon Skin (ARCS), an installation that has the ability to transform static, motionless architectural surfaces into interactive and engaging skins. Swarm algorithms drive the interactivity and responsiveness of this “virtual skin”. In particular, the virtual skin responds to colour, movements, and distance of surrounding objects. We provide a comprehensive description and analysis of the ARCS installation.

title	Frameworks for Computational Design of Textile Micro-Architectures and Material Behavior in Forming Complex Force-Active Structures
doi	https://doi.org/10.52842/conf.acadia.2013.281
source	ACADIA 13: Adaptive Architecture [Proceedings of the 33rd Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-1-926724-22-5] Cambridge 24-26 October, 2013), pp. 281-292
summary	Material behavior can be defined as the confluence of associative rules, contextual pressures and constraints of materialization. In more general terms, it can be parameterized as topologies, forces and materiality. Forming behavior means resolving the intricate matrix of deterministic and indeterministic factors that comprise and interrelate each subset of these material- nherent conditions. This requires a concise design framework which accumulates the confluent behavior through successive and cyclical exchange of multiple design modes, rather than through a single design environment or set of prescribed procedures. This paper unfolds a sequencing of individual methods as part of a larger design framework, described through the development of a series of complex hybrid- structure material morphologies. The “hybrid” nature reflects the integration of multiple force-active structural concepts within a single continuous material system, devising both self-organized yet highly articulated spatial conditions. This leads primarily to the development of what is termed a “textile hybrid” system: an equilibrium state of tensile surfaces and bending-active meshes. The research described in this paper looks to expose the structure of the textile as an indeterministic design parameter, where its architecture can be manipulated as means for exploring and differentiating behavior. This is done through experimentation with weft-knitting technologies, in which the variability of individual knit logics is instrumentalized for simultaneously articulating and structuring form. Such relationships are shown through an installation constructed at the ggggallery in Copenhagen, Denmark.

Online and Global. 24-30 October 2020. edited by B. Slocum, V. Ago, S. Doyle, A. Marcus, M. Yablonina, and M. del Campo. 340-349.
summary	This paper presents the design, control system, and elastic behavior of ELAbot: a robotic bending active textile hybrid (BATH) structure that can self-form and transform. In BATH structures, equilibrium emerges from interaction between tensile (form active) and elastically bent (bending active) elements (Ahlquist and Menges 2013; Lienhard et al. 2012). The integration of a BATH structure with a robotic actuation system that controls global deformations enables the structure to self-deploy and achieve multiple three-dimensional states. Continuous elastic material actuation is embedded within an adaptive cyber-physical network, creating a novel robotic architectural system capable of behaving autonomously. State-of-the-art BATH research demonstrates their structural efficiency, aesthetic qualities, and potential for use in innovative architectural structures (Suzuki and Knippers 2018). Due to the lack of appropriate motor-control strategies that exert dynamic loading deformations safely over time, research in this field has focused predominantly on static structures. Given the complexity of controlling the material behavior of nonlinear kinetic elastic systems at an architectural scale, this research focuses on the development of a cyber-physical design framework where physical elastic behavior is integrated into a computational design process, allowing the control of large deformations. This enables the system to respond to conditions that could be difficult to predict in advance and to adapt to multiple circumstances. Within this framework, control values are computed through continuous negotiation between exteroceptive and interoceptive information, and user/designer interaction.

summary	Irregular tensegrity structures, due to their non-linear behaviour, possess the potential ability to configure in multiple stable states. The kinematics and inherent properties of the compressive and tensile components govern the final static configuration of the system. The primary objective of the research is to study the non-linear behaviour of irregular tensegrity structures and formulate a computational generative, evaluative and algorithmic method to design a structurally dynamic tensegrity system, with inherent potential to adapt to the varying contexts and its respective demands, requirements and spatial needs.

summary	In order to achieve interactive architecture it is necessary to consider more than the technological components of sensors, controllers, and actuators. The interaction can be focused to different interaction activities: instructing, conversing, manipulating, and exploring (we propose to call this the interaction view). Additionally, the purpose of the building may range from performing, sustaining, servicing, symbolising, to entertaining (we propose to call this the world view). Combined, the interaction view and world view establish 20 different attitudes, which are flavours of behaviour for the interactive building. Through attitudes interaction profiles can be established and criteria derived for the design of interactive buildings.

summary	Governments in Australia are faced with policy implementation that mandates higher energy efficient housing (Foran, Lenzen & Dey 2005). To this effect, the National Construction Code (NCC) 2013 stipulates the minimum energy performance for residential buildings as 114MJ/m2 per annum or 6 stars on an energy rating scale. Compliance with this minimum is mandatory but there are several methods through which residential buildings can be rated to comply with the deemed to satisfy provisions outlined in the NCC. FirstRate5 is by far the most commonly used simulation software used in Victoria, Australia. Meanwhile, Building Information Modelling (BIM), using software such as ArchiCAD has gained a foothold in the industry. The energy simulation software within ArchiCAD, EcoDesigner, enables the reporting on the energy performance based on BIM elements that contain thermal information. This research is founded on a comparative study between FirstRate5 and EcoDesigner. Three building types were analysed and compared. The comparison finds significant differences between simulations, being, measured areas, thermal loads and potentially serious shortcomings within FirstRate5, that are discussed along with the future potential of a fully BIM-integrated model for energy rating certification in Victoria.

summary	Computer Aided Architectural Design (CAAD) decisions and judgments have been at the heart of architectural design practice. Despite the increasing popularity of computer aided design applications, measuring the decision making of designers empirically remains elusive. Past research claiming usefulness of the CAD has relied largely on anecdotal or case studies that are vulnerable to bias. The study reviews results of prior investigations. The relatively few laboratory experiments report hardly any empirical results regarding the measurement of CAD decision making. The study provides an overview of the literature of existing measurement methods that have been used in psychology and neuroscience to assess individual variations in design making, and highlight these different measurement methods’ strengths and weaknesses. We conclude with a comparative evaluation of the different measures and provide suggestions regarding their constructive use in building realistic theories of designer’s decision making measurement.

summary	Hyper-Morphology is an on-going research outlining a bottom-up evolutionary design process based on autonomous cellular building components. The research interfaces critical operational traits of the natural world (Evolutionary Development Biology, Embryology and Cellular Differentiation) with Evolutionary Computational techniques driven design methodologies. In the Hyper-Morphology research, genetic sequences are considered as sets of locally coded relational associations between multiple factors such as the amount of components, material based constraints, and geometric adaptation/degrees of freedom based adaptation abilities etc, which are embedded autonomously within each HyperCell component. Collective intelligence driven decision-making processes are intrinsic to the Hyper-Morphology logic for intelligently operating with autonomous componential systems (akin to swarm systems). This subsequently results in user and activity centric global morphology generation in real-time. Practically, the Hyper-Morphology research focuses on a 24/7 economy loop wherein real-time adaptive spatial usage interfaces with contemporary culture of flexible living within spatial constraints in a rapidly urbanizing world.

summary	Architectural design is a complex activity. The development of a building involves management of the diverse goals of a heterogeneous group of agents using no more than the discrete resources of a given setting. These variables can often conflict and result in rigid normative frameworks that can limit the capacity of a designer to respond with accuracy to diverse environmental factors. The main aim of this paper is to present the theoretical foundations of an evolutionary system to assist the customization of architecture under such prescribed design conditions.

summary	In relation to cities, wind is one of the less studied meteorological parameter. Constant vertical rate variations from meso scale to micro scale, altogether with strenght, direction, velocity of the urban canyon, makes the wind a complex subject of study. To achieve this, a methodological strategy that addresses the wind's multi dimensionality was raised. It was aplied to Punta Arenas, the southernmost city in the world, where most of the time winds come 90% from the same direction with speeds reaching 128 km/h. Wind's constant directional behavior allows the recognition of areodynamic phenomena produced, in the first instance, for the wind profiles influenced by the urban rugosity and then, at morphologycal level, the aerodynamic behavior of the layered fluids over the building bodies, generating a regular pattern between solids and fluids. The strong winds in cities with cold climate influence the use of public spaces, which, not being designed under this conditions, do not develop proper levels of thermal comfort.

summary	This paper proposes an overview on the relation between representation, technology and architecture methodologies. Focusing on disposable digital tools, it reaches the new tools of virtual immersive 3D architectural environments. It also addresses the concepts of operative 3D, augmented reality and robotic manufacturing, thus introducing a system of digital tools that enables users to step inside a 3D virtual reality environment, built as a virtual building prototype, and to use all data instructions directly with the construction industry. This paper questions therefore the traditional processes and perceptions in architecture and draw present and future advanced state-of-the-arts methodologies. As a result, future and tradition in architectural design methods are challenged. Recognizing the permanent tensions between traditional and innovative processes, possible methodological changes are put in perspective, namely the fields of technical representation, building construction and design processes.

summary	I have conducted a study to explore aerodynamic performance as a driver for skyscraper design, utilizing up-to-date parametric design and computational fluid dynamics (CFD) technologies readily available to architects. Previous scientific research has suggested strategies in modifying the form of skyscrapers for the purpose of improving their aerodynamic performance. I have incorporated six of such strategies into parametric design tool to produce a matrix of 60 prototypes. These prototypes are subjected to qualitative and quantitatively evaluation iterations to yield the most optimized design, with considerations given primarily to aerodynamic performance, and secondarily to structural robustness, program potential, and image attractiveness. The selected design option is further developed into a skyscraper concept. A multi-staged aerodynamic performance-driven design process is the most important result of the study. In addition, two valuable insights have been obtained: first, to inject a new inspiration into the design of skyscrapers, I have implemented the MultiDisciplinary Optimization (MDO) methodology from the aerospace industry. Second, I am able to support form-generation parametric design by quantitative evaluation process.

summary	Natural surveillance is one key factor proposed, in the approach to decrease fear of crime. Building fenestrations and outdoor spaces like terrace, balconies and verandas that extend the interior spaces and the indoor activities, beyond the closed external shell of the buildings, are proposed by CPTED, in their place specific policy guidelines, to help design out fear and crime. In this background, this study on natural surveillance opportunities, explores typological variations of these component outdoor spaces of buildings, in line with variations in size and location. The affordances considered for this study specifically focus on the ways in which these spaces structure the visual fields for the external observer. This paper thus reports the survey of visual preferences exploring the spatial affordances of building spaces and their association with fear of crime.

summary	A method for fusion of perceptions is presented. It is based on probabilistic treatment of perception, where perception quantifies the chance an unbiased observer sees an environmental object, and the associated probability can be interpreted as degree of awareness for the object. The approach uniquely accounts for the fact that final realization or remembrance of a scene in the brain may be absent or elusive, so that it is subject to probabilistic considerations. For objects that are to be perceived from multiple viewpoints, such as a sculpture in a museum, or a building in its urban context, the probabilistic approach uniquely defines the fusion of perceptions. This is accomplished by carrying out the probabilistic union of events. The computation is presented together with its geometric implications, which become rather intricate for multiple observers, whereas the computation is straight forward. The method is exemplified for two applications in architectural design at different scales, namely interior and urban design, indicating the generic nature as well as the large application potential of the method.
