summary	Space syntax is supposed to be an objective method for evaluating spatial configurations. Its contribution to a design process is dependent on the designer’s estimation. The paper describes a generative approach to finding particularly good interventions based on space syntax analyses of axial maps. More precisely, a case study was undertaken through applying such a strategy to improve and connect a segregated street network of an informal settlement to its neighbourhood. Controlling and redirecting movement in slums may cause positive effects. This research is based on and inspired by a consulting project by the company Space Syntax Limited for the Municipality of Jeddah, Saudi Arabia, in which the consulting company designed a regeneration program for declining informal settlements.

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.

title	Textile Logics in a Digital Architecture

summary	This paper questions the representational logics of a new class of digital-material practices incorporating material performance. Presenting the concept of ‘textile logic’, the paper discusses how computational design tools that allow for a parametrisation of material behaviour are foregrounding the examination of structural principles that lie outside traditional compressive logic. By pointing to the structural thinking of Vladimir Shukhov, Buckminster Fuller and Robert Le Ricolais, as well as contemporary practitioners such as Cecil Balmond and Peter Testa the paper examines the precedents for incorporating tensile self-bracing as a structural principle and how textiles can become a model for architectural design. The paper presents the research by design enquiry ‘Shadow Play’ examining the involved traditions, methods and material practices of textile design and the here embedded systems of material specification can be advantageously ported to digital design.

summary	Cast Thicket is a prototypical instillation that furthers earlier research into tensile concrete molds through the use of plastic formwork and a layered structural network. Leveraging the fluid materiality of concrete and the machinability of polypropylene, Cast Thicket creates a lacy network of thin members that disperse and coalesce to address structural and spatial needs. Proposed as an application for tall concrete buildings, the research responds to the 2012 APPLIED: Research through Fabrication competition.

title	Conventions of Control: A Catalog of Gestures for Remotely Interacting With Dynamic Architectural Space
doi	https://doi.org/10.52842/conf.acadia.2012.429
source	ACADIA 12: Synthetic Digital Ecologies [Proceedings of the 32nd Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-1-62407-267-3] San Francisco 18-21 October, 2012), pp. 429-438
summary	The intent of this project is to create a catalogue of gestures for remotely controlling dynamic architectural space. This research takes an essential first step towards facilitating the field of architecture in playing a role in developing an agenda for control. The process of the project includes a sequence carried out in four stages: 1) Research of gestural control 2) Creating an initial catalogue of spatial architectural gestures 3) Real-world testing and evaluation and 4) Refining the spatial architectural gestures. In creating a vocabulary for controlling dynamic architectural environments, the research builds upon the current state-of-the-art of gestural control which exists in integrated touch- and gesture-based languages of mobile and media interfaces. The next step was to outline architecturally specific dynamic situational activities as a means to explicitly understand the potential to build gestural control into systems that make up architectural space. A proposed vocabulary was then built upon the cross-referenced validity of existing intuitive gestural languages as applied to architectural situations. The proposed gestural vocabulary was then tested against user-generated gestures in the following areas: frequency of "invention", learnability, memorability, performability, efficiency, and opportunity for error. The means of testing was carried out through a test-cell environment with numerous kinetic architectural elements and a Microsoft Kinect Sensor to track gestures of the test subjects. We conclude that the manipulation of physical building components and physical space itself is more suited to gestural physical manipulation by its users instead of control via device, speech, cognition, or other. In the future it will be possible, if not commonplace to embed architecture with interfaces to allow users to interact with their environments and we believe that gestural language is the most powerful means control through enabling real physical interactions.

title	Diagramming in a digital environment
doi	https://doi.org/10.52842/conf.caadria.2012.151
source	Proceedings of the 17th International Conference on Computer Aided Architectural Design Research in Asia / Chennai 25-28 April 2012, pp. 151–160
summary	Research into digital design environments has explored modelling, generating and testing design propositions. When considering the broader design literature, however, we notice that a significant contribution to design is absent, that of diagramming. In the realm of architectural theory discourse in the past few years, diagramming has been much discussed with many interpretations of the activity. This paper will demonstrate that the development of digital techniques can change dramatically our ability to conceptualise and produce generative diagrams as previously not possible. The paper will follow the work done at the in the Melbourne School of Design. We will demonstrate how students are introduced to diagramming techniques and shown how to formulate a concept, then a program generator and to test a final proposal. The paper will also demonstrate how digital techniques can dramatically change the way we conceptualise and approach design problems. In this repeated teaching technique, we illustrate how digital systems contribute to conceptual diagrams and this contributes to the larger theoretical debate on diagramming techniques by introducing digital perspectives. The paper will therefore contribute to discussion on the ways in which digital systems can be engaged in substantive architectural teaching beyond the rote application of proprietary software and representative approaches.

summary	We canvas issues in using neural imaging via EEG to map human responses to spaces. We describe the technology, some experiments by others relevant to architecture, and two of our own studies. One involves testing EEG as a supplement to user preference studies of urban typologies. The second involves recording the movement and affective (emotional) states of a pedestrian while moving through open spaces in Edinburgh. We produce map overlays of several such walkers as a method of mapping responses to urban spaces.

title	Generation and Integration of an Aerodynamic Performance Data Base Within the Concept Design Phase of Tall Buildings
doi	https://doi.org/10.52842/conf.acadia.2012.087
source	ACADIA 12: Synthetic Digital Ecologies [Proceedings of the 32nd Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-1-62407-267-3] San Francisco 18-21 October, 2012), pp. 87-96
summary	Despite the fact that tall buildings are the most wind affected architectural typology, testing for aerodynamic performance is conducted during the later design phases well after the overall geometry has been developed. In this context, aerodynamic performance studies are limited to evaluating an existing design rather than a systematic performance study of design options driving form generation. Beyond constrains of time and cost of wind tunnel testing, which is still more reliable than Computational Fluid Dynamics (CFD) simulations for wind conditions around buildings, aerodynamic performance criteria lack an immediate interface with parametric design tools. This study details a framework for empirical data collection through wind tunnel testing of building mechatronic models and the expansion of the collected dataset by determining a mathematical interpolating model using an Artificial Neural Network (ANN) algorithm developing an Aerodynamic Performance Data Base (APDB). Frederick Keisler called the interacting of forces CO-REALITY, which he defined as The Science of Relationships. In the same article Keisler proclaims that the Form Follows Function is an outmoded understanding that design must demonstrate continuous variability in response to interactions of competing forces. This topographic space is both constant and fleeting where form is developed through the broadcasting of conflict and divergence as a system seeks balance and where one state of matter is passing by another; a decidedly fluid system. However, in spite of the fact that most of our environment consists of fluids or fluid reactions, instantaneous and geologic, natural and engineered, we have restricted ourselves to approaching the design of buildings and their interactions with the environment through solids, their properties and geometry; flow is considered well after the concept design stage and as validation of form. The research described herein explores alternative relations between the object and the flows around it as an iterative process, moving away from the traditional approach of Form Follows Function to Form Follows Flow.

title	A Closer Perspective on Fabrication Realities

summary	Digital Fabrication has arguably stirred the return of the architect to the long-held position as a master builder. The close engagement with materials offered by the digital fabrication technologies places necessary limitations and calls the architects for a deeper understanding of and awareness about the fabrication realities during the design process. The research conducted uses parametric modeling for the alteration of the design according to a wide range of infl uences, one of which is fabrication. This paper offers a close perspective on some fabrication necessities and limitations that emerged through the manufacturing of a number of scaled models of a parametrically designed shed and a full scale pavilion. The scope of this work falls into the realm of physical testing, tolerance, structure and assembly. It also points out the fabrication parameters that were part of the digital setting used to create the physical models. The paper argues that craft is still practically alive when deploying digital technologies as it has been ever present in the pre-digital era.

title	Prototype Implementation of a Loosely Coupled Design Performance Optimisation Framework
doi	https://doi.org/10.52842/conf.caadria.2013.675
source	Open Systems: Proceedings of the 18th International Conference on Computer-Aided Architectural Design Research in Asia (CAADRIA 2013) / Singapore 15-18 May 2013, pp. 675-684
summary	Integration of analyses into early design phases poses several challenges. An experimental implementation of an analysis framework in conjunction with an optimization framework ties authoring and analysis tools together under one umbrella. As a prototype it served intensive use-testing in the context of the SmartGeometry 2012 workshop in Troy, NY. In this prototype the data flow uses a mix of proprietary and publicised file formats, exchanged through publicly accessible interfaces. The analysis framework brokers between the parametric authoring tool and the analysis tools. The optimization framework controls the processes between the authoring tool and parametric engine on one side and the optimization algorithm on the other. In addition to some user-implemented analyses inside the parametric design model the prototype makes energy analysis and structural analysis available. The prototype allows testing assumptions about work flow, implementation, usability and general feasibility of the pursued approach.

title	A Digital Model for Fabric Formwork Panels: Using Physical Data to Train the Digital Model
doi	https://doi.org/10.52842/conf.ecaade.2012.2.159

summary	In the context of a wider inquiry on the integration of material properties and construction processes in computational models, this paper proposes a digital model for fabric formwork panels. Plaster cast in different types of fabric can produce a significant variation of resulting forms. The aim is to investigate whether data retrieved from physical models with 3D scanning techniques can improve the accuracy and efficiency of a simulation based on geometric principles, and better predict the behaviour of cast material in relation to the type of fabric. Setting up the computational model and choosing its parameters and constraints is based on the physical construction process, highlighting the relationship between material and form. As part of the cyclical exchange, evaluation of the digital model with physical testing demonstrates that the simulation can actually be trained by reducing the physical/ digital discrepancies.

summary	The potential afforded by the open search spaces of both agent-based models and evolutionary engines have given architecture yet another set of computational tools to play with, yet more often than not, they are used in isolation from one another. This research explores the set of techniques and results of having combined swarm formations, FEM software and an evolutionary engine within a parametric modeling environment such that they induce structurally intelligent swarm (SIS) morphologies. These morphologies are situated within normative architectural assemblies by means of parametric grafting techniques. Savage gothic materiality, as described by John Ruskin, as well as the work of Eva Hesse are referenced as the basis for these explorations. Speculations are made as to refining the engineering capabilities, expanding on programmatic applications and testing integrated SIS assemblies at larger scales.

title	Design Ecologies for Responsive Environments: Resonant Chamber, an Acoustically Performative System"

summary	This paper positions the development and performance of a responsive acoustic envelope system, called Resonant Chamber, within significant discourses in ecology, systems theory and cybernetics. The project is developed through two dominant threads. First, the synthetic design process that entails engaging simultaneous computational and physical investigations which inform each other through various feedback and control regimes - from simulation and testing frameworks to material limits and behaviors to geometric, technological and manufacturing limitations or constraints. Second, the paper elaborates on the system's embedded sensing, communication, feedback and actuation system that transforms its performance to a kinetic, responsive environment that opens up possibilities for active acoustic control, as well as open-ended interaction and play with inhabitants. Within this paradigm, the designer operates through an adaptive mode, between control and the dynamic shaping of possibilities within digital, physical and effective logics, constraints and opportunities.

summary	This paper sets out to introduce and explore a computational tool, thus a methodological framework, for simulating stress driven material growth and organization by employing a multi-agent system based in swarm intelligence algorithms. It consists of an ongoing investigation that underlies the intention for the material system to be perceived as design itself. The algorithm, developed in the programming language Processing, is operating in a bottom-up manner where components and data fl ows are self-organized into design outputs. An evaluation process, via testing on different design cases, is providing a coherent understanding on the system’s capacity to address an acceptable, within the “state-of-the-art” context, solution to material optimization and innovative form-finding. The analysis of the exported data is followed by a possible reconfi guration of the algorithm’s structure and further development by introducing new elements.

title	Progress Towards Multi-Criteria Design Optimisation Using Designscript With Smart Form, Robot Structural Analysis and Ecotect Building Performance Analysis"
doi	https://doi.org/10.52842/conf.acadia.2012.047

summary	Important progress towards the development of a system that enables multi-criteria design optimisation has recently been demonstrated during a research collaboration between Autodesk’s DesignScript development team, the University of Bath and the engineering consultancy Buro Happold. This involved integrating aspects of the Robot Structural Analysis application, aspects of the Ecotect building performance application and a specialist form finding solver called SMART Form (developed by Buro Happold) with DesignScript to create a single computation environment. This environment is intended for the generation and evaluation of building designs against both structural and building performance criteria, with the aim of expediently supporting computational optimisation and decision making processes that integrate across multiple design and engineering disciplines. A framework was developed to enable the integration of modeling environments with analysis and process control, based on the authors’ case studies and experience of applied performance driven design in practice. This more generalised approach (implemented in DesignScript) enables different designers and engineers to selectively configure geometry definition, form finding, analysis and simulation tools in an open-ended system without enforcing any predefined workflows or anticipating specific design strategies and allows for a full range of optimisation and decision making processes to be explored. This system has been demonstrated to practitioners during the Design Modeling Symposium, Berlin in 2011 and feedback from this has suggested further development.

summary	A parametric urban design system integrating GIS data in a CAD environment is proposed as a platform for discussing urban plans providing flexibility and information access in an interactive fashion. The proposed system links calculations of urban indicators with the parameter manipulation of the layout geometry, therefore allowing for a systematic update of indicators according to design modifi cations. Hence, design may be fine-tuned in an informed manner enhancing the quality of design decisions.

title	Zero-Waste, Flat-Packed, Tri-Chord Truss: Continued Investigations of Structural Expression in Parametric Design"
doi	https://doi.org/10.52842/conf.acadia.2012.199
source	ACADIA 12: Synthetic Digital Ecologies [Proceedings of the 32nd Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-1-62407-267-3] San Francisco 18-21 October, 2012), pp. 199-208
summary	The direct and rapid connections between scripting, modeling and prototyping allow for investigations of computation in fabrication. The manipulation of planar materials with two-dimensional CNC cuts can easily create complex and varied forms, volumes, and surfaces. However, the bulk of research on folding using CNC fabrication tools is focused upon surfaces, self-supporting walls and shell structures, which do not integrate well into more conventional building construction models. This paper attempts to explain the potential for using folding methodologies to develop structural members through a design-build process. Conventional building practice consists of the assembly of off-the-shelf parts. Many times, the plinth, skeleton, and skin are independently designed and fabricated, integrating multiple industries. Using this method of construction as an operative status quo, this investigation focused on a single structural component: the truss. Using folding methodologies and sheet steel to create a truss, this design investigation employed a recyclable and prolific building material to redefine the fabrication of a conventional structural member. The potential for using digital design and two-dimensional CNC fabrication tools in the design of a foldable truss from sheet steel is viable in the creation of a flat-packed, minimal waste structural member that can adapt to a variety of aesthetic and structural conditions. Applying new methods to a component of the conventional ‘kit of parts’ allowed for a novel investigation that recombines zero waste goals, flat-packing potential, structural expression and computational processes. This paper will expand (greatly) upon previous research into bi-chord truss designs, developing a tri-chord truss, which is parametrically linked to its structural moment diagram. The cross section of each truss is formed based on the loading condition for each beam. This truss design has been developed through a thorough series of analytical models and tests performed digitally, to scale and in full scale. The tri-chord truss is capable of resisting rotational failures well beyond the capacity of the bi-chord designs previously developed. The results are complex, and elegant expressions of structural logics embodied in a tightly constrained functional design.

source	International Journal of Architectural Computing vol. 10 - no. 4, 555-574
summary	Sustainable design assessment requires information, which is aggregated from different phases of a building design, and evaluated according to criteria specified in a ‘sustainable building rating system.’ In the architecture engineering and construction (AEC) domain much of the necessary information is available through open source data standards such as Industry Foundation Classes (IFC). However, no single standard that provides support for sustainability assessment completely suffices as a data structure. This paper explores the augmentation of the Construction Operations Building information exchange (COBie) model, as an intermediary data structure, to bridge between requirements of the Leadership in Energy and Environmental Design (LEED) rating system and a building information model. Development of a general framework for data sharing and information management for LEED assessments is illustrated through an implementation of a prototype using functional databases.The prototype checks and augments available data as needed, which is used to populate LEED submission templates.

title	Resilient Rules - Culture and Computation in Traditional Built Environments
source	CAAD \| INNOVATION \| PRACTICE [6th International Conference Proceedings of the Arab Society for Computer Aided Architectural Design (ASCAAD 2012 / ISBN 978-99958-2-063-3], Manama (Kingdom of Bahrain), 21-23 February 2012, pp. 211-221
summary	This study explores the influence of the socio-cultural rules, based upon Islamic jurisprudence (fiqh), on the complexity of the traditional built environment. This system of rules organized the societal activities, including decisions and activities related to design and construction in the Arab-Islamic city. Considering the city as a complex system, the study will try to show how this rules system made the Arab-Islamic city resilient and adaptive. Complex Adaptive Systems (CAS) are non-linear, self-organizing systems that have the ability to adapt to changing conditions through changing the rules that organize the random autonomous interactions between agents in the environment. This adaptation takes place through gradual gained experience that is reflected in the behavior of agents. This study attempts to interrelate different bodies of literature (Complexity/Chaos theory and built environment studies) in a single framework that aims to show that the socio-cultural rules system based on fiqh was a major factor in the resilience of the traditional built environment. These interrelations are illustrated using a graph called Computational Rules Graph (CRG). The CRG relates the traditional rules system to attributes of complex systems in a graph that can be modeled computationally. Traditional rules (codes of conduct) are proscriptive (non-deterministic), defining what is prohibited, thereby producing autonomous environments where agents had control over their immediate environment. In comparison, contemporary rules of the built environment (building codes) are prescriptive (deterministic), subscribing definite actions that need to take place by the stake-holder (agent) neglecting user needs and preferences. The application of these traditional rules system increased the agent’s autonomy and freedom of action. It also helped establish stronger social networks among agents, which resulted in a resilient environment.

title	Automation at scale: Geometry, analysis and post processing
doi	https://doi.org/10.52842/conf.caadria.2012.017

summary	Our team is currently engaged in the peer review of a large steel stadium dome roof. The roof has a diameter of approximately 300m and rises to over 70m in elevation. In addition to its size, the roof also contains a moveable component which can be deployed during inclement weather. The roof structure comprises of approximately 32,000 beams with 10,000 nodes. This paper overviews our efforts in scaling digital design techniques with regards to automation and parametric geometry to expedite the verification of structural members and geometrically complicated connection nodes. The paper will discuss two realms where automation was deployed. The first realm is the verification of Type 1 node connections where less than eight members intersect at a single work point and is relatively geometrically simple. Type 1 nodes were checked against published code requirements. Type 2 connections consisted of nodes where more than eight members intersected or bracing angles did not meet code guidelines. Type 2 nodes were verified using the finite element method and large scale automation of node geometry creation to structural analysis post processing was employed.
