title	Multi-Machine Fabrication: An Integrative Design Process Utilising an Autonomous UAV and Industrial Robots for the Fabrication of Long-Span Composite Structures
doi	https://doi.org/10.52842/conf.acadia.2017.248
source	ACADIA 2017: DISCIPLINES & DISRUPTION [Proceedings of the 37th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-0-692-96506-1] Cambridge, MA 2-4 November, 2017), pp. 248-259
summary	Fiber composite materials have tremendous potential in architectural applications due to their high strength-to-weight ratio and their ability to be formed into complex shapes. Novel fabrication processes can be based on the unique affordances and characteristics of fiber composites. Because these materials are lightweight and have high tensile strength, a radically different approach to fabrication becomes possible, which combines low-payload yet long-range machines—such as unmanned aerial vehicles (UAV)—with strong, precise, yet limited-reach industrial robots. This collaborative concept enables a scalable fabrication setup for long-span fiber composite construction. This paper describes the integrated design process and design development of a large-scale cantilevering demonstrator, in which the fabrication setup, robotic constraints, material behavior, and structural performance were integrated in an iterative design process.

title	Optically Illusive Architecture: Producing Depthless Objects Using Principles of Linear Perspective
doi	https://doi.org/10.52842/conf.acadia.2017.274
source	ACADIA 2017: DISCIPLINES & DISRUPTION [Proceedings of the 37th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-0-692-96506-1] Cambridge, MA 2-4 November, 2017), pp. 274-283
summary	Architecture is a discipline with a long history of engagement with representational techniques borrowed from artforms such as painting and drawing. Historically, these techniques enable artists to translate three-dimensional space into a two-dimensional medium, while architecture tends to work in reverse, using the latter to express yet-to-be-realized projects in the former. This investigation leads to specific methods of linear perspectival representation that manipulate our perception of spatial depth, such as trompe l’oeil and anamorphic projection. Referencing these methods, we introduce the concept of an optically illusive architecture. While referencing a wide range of visually deceptive effects, we focus on synthesizing two-dimensional patterns into three-dimensional objects for the purpose of producing a depthless reading of three-dimensional space. In this paper, we outline optically illusive architecture and look at the initial stages of a design experiment that attempts to bring the perception of flatness into a three-dimensional object. This is achieved by building a simple algorithm that reverses linear perspectival projection to produce two-dimensional effects through a three-dimensional physical object. We analyze the results by comparing the two- and three-dimensional projections against one another from varying points of view in space, and speculate on the possible applications for such a design.

title	Teaching Design by Coding in Architecture Undergraduate Education: A Case Study with Islamic Patterns

summary	Computer-aided design has found its role in the undergraduate education of architects, and presently design by coding is also gradually finding further prominence in accord with the increasing demand by students who wish to learn more about this topic. This subject is included in an integrated manner in some studio courses on architecture design in some schools, or it is taught separately in elsewhere. In terms of the separate course on coding, the principal difficulty is that actual applications of the method can rarely be included due to time limitations and the fact that it is conducted separately from the studio course on architecture. However, within the framework of the architectural education, in order to learn about the coding it is necessary to consider it along with the design process, and this versatile thinking can only be achieved by the application of the design. In this study, an elective undergraduate course is considered in the context of design and to yield a versatile thinking strategy while learning the language of visual programming. The course progressed under the theoretical framework of shape grammar from the design stage through to the digital fabrication process, and the experimental studies were carried out on the selected topic of Islamic pattern. A method was proposed to improve the productivity of such courses, and an evaluation of the results is presented.

summary	This paper presents the initial developments of a method to train an adaptive robotic system for subtractive manufacturing with timber, based on sensor feedback, machine-learning procedures and material explorations. The methods were evaluated in a series of tests where the trained networks were successfully used to predict fabrication parameters for simple cutting operations with chisels and gouges. The results suggest potential benefits for non-standard fabrication methods and a more effective use of material affordances.

title	Hydroassemblies - Unit-based system for the symbiosis of urban spaces and greeneries through hydraulic driven tectonics
doi	https://doi.org/10.52842/conf.ecaade.2017.1.661

summary	Hydroassemblies is a research thesis that investigates the architectural potential of a unit-based modular system that can recursively grow in space guided by hydrodynamic principles in order to generate intricate tectonic assemblies, integrating the roles of spatial articulator, water collector/distributor and plant cultivation substrate to foster a symbiotic relation with the urban environment. By implementing principles of circulatory systems in biology, the authors developed a system that grows through recursive formation of loops and articulates its tectonic via a continuous, interconnected branching network. The founding process improves upon a combinatorial algorithm of discrete parts, considering how iterative interactions at the local level have a feedback impact on the growth process at the whole system scale. The paper explores how features, spatial and perceptive qualities, affordances and opportunities emerge at the global scale of the formation from the interplay of local behavioral principles and environmental conditions. The provided implementation is a proof of concept of the production of complex qualities by means of massive quantities of simple elements and interactions.

title	SILVEREYE– the implementation of Particle Swarm Optimization algorithm in a design optimization tool
source	Gülen Çagdas, Mine Özkar, Leman F. Gül and Ethem Gürer (Eds.) Future Trajectories of Computation in Design [17th International Conference, CAAD Futures 2017, Proceedings / ISBN 978-975-561-482-3] Istanbul, Turkey, July 12-14, 2017, p. 667.
summary	Engineers and architects are now turning to use computational aids in order to analyze and solve complex design problems. Most of these problems can be handled by techniques that exploit Evolutionary Computation (EC). However existing EC techniques are slow [8] and hard to understand, thus disengaging the user. Swarm Intelligence (SI) relies on social interaction, of which humans have a natural understanding, as opposed to the more abstract concept of evolutionary change. The main aim of this research is to introduce a new solver Silvereye, which implements Particle Swarm Optimization (PSO) in the Grasshopper framework, as the algorithm is hypothesized to be fast and intuitive. The second objective is to test if SI is able to solve complex design problems faster than ECbased solvers. Experimental results on a complex, single-objective high-dimensional benchmark problem of roof geometry optimization provide statistically significant evidence of computational inexpensiveness of the introduced tool.

summary	The increased need for optimization in design processes has led BIM software users to customize their projects by the use of programming and external applications. This paper presents the state of art of Revit plug-ins by means of an explorative, quantitative study of current repositories and the proposition of a categorization system to identify to which purposes the tools are being developed. Then, through a questionnaire to AEC professionals, assessment on the use and necessity of the tools is made by comparing the user experience with the proposed state of art categories.

title	A Multisensory Computational Model for Human-Machine Making and Learning
doi	https://doi.org/10.52842/conf.acadia.2017.238
source	ACADIA 2017: DISCIPLINES & DISRUPTION [Proceedings of the 37th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-0-692-96506-1] Cambridge, MA 2-4 November, 2017), pp. 238-247
summary	Despite the advancement of digital design and fabrication technologies, design practices still follow Alberti’s hylomorphic model of separating the design phase from the construction phase. This separation hinders creativity and flexibility in reacting to surprises that may arise during the construction phase. These surprises often come as a result of a mismatch between the sophistication allowed by the digital technologies and the designer’s experience using them. These technologies and expertise depend on one human sense, vision, ignoring other senses that could be shaped and used in design and learning. Moreover, pedagogical approaches in the design studio have not yet fully integrated digital technologies as design companions; rather, they have been used primarily as tools for representation and materialization. This research introduces a multisensory computational model for human-machine making and learning. The model is based on a recursive process of embodied, situated, multisensory interaction between the learner, the machines and the thing-in-the-making. This approach depends heavily on computational making, abstracting, and describing the making process. To demonstrate its effectiveness, I present a case study from a course I taught at MIT in which students built full-scale, lightweight structures with embedded electronics. This model creates a loop between design and construction that develops students’ sensory experience and spatial reasoning skills while at the same time enabling them to use digital technologies as design companions. The paper shows that making can be used to teach design while enabling the students to make judgments on their own and to improvise.

title	Architecture-Human-Machine (re)configurations - Examining computational design in practice

summary	This paper outlines a research project that explores the participation in, and perception of, advanced technologies in architectural professional practice through a sociotechnical lens and presents empirical research findings from an online survey distributed to employees in five large-scale architectural practices in Sydney, Australia. This argues that while the computational design paradigm might be well accepted, understood, and documented in academic research contexts, the extent and ways that computational design thinking and methods are put-into-practice has to date been less explored. In engineering and construction, technology adoption studies since the mid 1990s have measured information technology (IT) use (Howard et al. 1998; Samuelson and Björk 2013). In architecture, research has also focused on quantifying IT use (Cichocka 2017), as well as the examination of specific practices such as building information modelling (BIM) (Cardoso Llach 2017; Herr and Fischer 2017; Son et al. 2015). With the notable exceptions of Daniel Cardoso Llach (2015; 2017) and Yanni Loukissas (2012), few scholars have explored advanced technologies in architectural practice from a sociotechnical perspective. This paper argues that a sociotechnical lens can net valuable insights into advanced technology engagement to inform pedagogical approaches in architectural education as well as strategies for continuing professional development.

summary	This talk describes the foundational concepts of cognitive design computing and then presents some examples. Cognitive computing is concerned with modeling human cognition computationally and using that model as the foundation for constructing computer models of design activities. Human cognition is based on perception, learning and adaptation. Here we present human cognition in terms of situated cognition - cognition involving interaction with an environment. The talk briefly introduces a set of principles for cognitive design computing founded on the three concepts of interaction, constructive memory and situatedness. It then presents two examples of applications of this approach.

summary	The development and the innovation of tools, techniques and digital applications represent a challenge for those who are in charge of architectural education to keep up with this development. This is because these techniques provide potentials that are not available in the traditional method of teaching. This raises an important question: can these tools and techniques help to achieve the targeted outcomes of education? This research paper discusses how to integrate both digital 3D models, of CAAD, and interactive applications for the development of architectural education curriculum. To test this, a case study has been conducted on the subject of building construction, for the second year at the faculty of engineering, specifically, the bearing walls construction system. In addition, this study has been divided into three parts. Through the first part, the scientific content of the curriculum, which tackles the bearing walls, has been prepared. The second part shows how to convert the scientific content into an interactive content in which the students learn through the experiment and the simulation of the traditional construction methods as the students a acquire construction skills and the ability to imagine different structural complexities. The third part includes the creation of both the application and the software containing the interactive curriculum. Workshop for the students has been held as a case study to test the effectiveness of this development and to recognize the pros and cons. The results confirmed the importance of integrating this applications into architectural education.

title	HalO [Indoor Positioning Mobile Platform]: A Data-Driven, Indoor-Positioning System With Bluetooth Low Energy Technology To Datafy Indoor Circulation And Classify Social Gathering Patterns For Assisting Post Occupancy Evaluation

summary	Post-Occupancy Evaluation (POE) as an integrated field between architecture and sociology has created practical guidelines for evaluating indoor human behavior within a built environment. This research builds on recent attempts to integrate datafication and machine learning into POE practices that may one day assist Building Information Modeling (BIM) and multi-agent modeling. This research is based on two premises: 1) that the proliferation of Bluetooth Low Energy (BLE) technology allows us to collect a building user’s data cost-effectively and 2) that the growing application of machine learning algorithms allows us to process, analyze and synthesize data efficiently. This study illustrates that the mobile platform HalO can serve as a generic tool for datafication and automation of data analysis of the movement of a building user. In this research, the iOS mobile application HalO, combined with BLE beacons enable building providers (architects, developers, engineers and facility managers etc.) to collect the user’s indoor location data. Triangulation was used to pinpoint the user’s indoor positions, and k-means clustering was applied to classify users into different gathering groups. Through four research procedures—Design Intention Analysis, Data Collection, Data Storage and Data Analysis—the visualized and classified data helps building providers to better evaluate building performance, optimize building operations and improve the accuracy of simulations.

title	3D Visual Simulation and Numerical Measurement of Privacy in Traditional Korean Palace
doi	https://doi.org/10.52842/conf.caadria.2017.355

summary	Traditional Korean architecture provides privacy through a proper balance of openness and enclosure through courtyard gardens. However, it is difficult to analyse privacy quantitatively in a three-dimensional space. The analysis of visual privacy is a significant issue in resolving conflicts and enhancing comfort. This paper develops a computational algorithm for simulating and measuring privacy on the concept of prospect and refuge: a design strategy for psychological wellbeing. In order to visualize privacy, the prospect area ratio (PAR) and refuge area ratio (RAR) are used in 3D visual simulations. PAR and RAR calculate the area ratio of the hiding space or the visible space in the images collected from the 3D model. In addition, parametric algorithms are proposed to calculate PAR/RAR automatically. Finally, this research demonstrates a case study of Gyeongbokgung, one of the five palace buildings in Korea, to show methods and processes of the quantitative analysis of visual privacy. The outcome of this paper contributes to quantitative confirmation of spatial characteristics that clearly distinguish between public space and private space of Gyeongbokgung. The proposed method also shows great potentials to quickly obtain the numeric value of privacy.

summary	GrowMorph is an ongoing research project that addresses the logic of bacterial cellular growth and its potential uses in architecture and design. While natural forms have always been an inspiration for human creativity, contemporary technology and scientific knowledge can allow us to advance the principle of biomimesis in striking new directions. By examining various patterns of bacterial growth, including their parametric logic, their use of responsive membranes and scaffolding structures, and their environmental fitness, this research creates new algorithmic design and construction models that can be applied through digital fabrication. Based on data from confocal microscopy, simulations were created using programming language Processing to model the environmental responses and morphology of the bacteria's growth. To demonstrate the utility of the results, the simulations created in this research were used to design an organically shaped pavilion and to suggest a new digital knitting process for material construction. The results from the study can inspire designers to make use of bacterial growth logic in their work, and provide them with practical tools for this purpose. Potential applications include novel designs for responsive surfaces, new fabrication processes, and unique spatial structures in future architectural work.

title	Embodied Computation – An Actuated Active Bending Tower: Using Simulation-Model-Free Sensor Guided Search To Reach Posture Goals
doi	https://doi.org/10.52842/conf.acadia.2017.324
source	ACADIA 2017: DISCIPLINES & DISRUPTION [Proceedings of the 37th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-0-692-96506-1] Cambridge, MA 2-4 November, 2017), pp. 324- 329
summary	The concept of Embodied Computation is to leverage the combination of abstract computational and material artifact as a method for exploration in the design process. A common approach for the integration of the two realms is to use computational simulation based on the geometric form of the artifact for the prediction of material behavior. This leads to the integration of a geometric model abstraction of the physical artifact into the control software of the actuated device and can produce deviations between the state of the physical construct and the computational state. Here an alternative approach of a soft, actuated, active bending structure is explored. Six fluidic actuators are combined with a six degree of freedom (DOF) sensor for posture feedback. Instead of relying on simulated kinematics to reach a particular posture, the sensor-enabled posture feedback guides a simplex search algorithm to find combinations of pressures in the six actuators that minimize the combined tilting angles for the goal of a level tower top. Rather than simulating the structure computationally, the model is shifted to one of feedback and control, and the structure operates as a physical equation solver returning an x-y-z tilting angle for every set of actuation pressures. Therefore the computational model of the search process is independent of the physical configuration of the structure itself and robust to changes in the environment or the structure itself. This has the future potential for more robust control of non-determined structures and constructs with heterogeneous DOF common in architecture where modeling behavior is difficult.

summary	In this paper, we present a method for generating fast conceptual urban design prototypes. We synthesize spatial configurations for street networks, parcels and building volumes. Therefore, we address the problem of implementing custom data structures for these configurations and how the generation process can be controlled and parameterized. We exemplify our method by the development of new components for Grasshopper/Rhino3D and their application in the scope of selected case studies. By means of these components, we show use case applications of the synthesis algorithms. In the conclusion, we reflect on the advantages of being able to generate fast urban design prototypes, but we also discuss the disadvantages of the concept and the usage of Grasshopper as a user interface.

summary	In this paper we present our research which is focused on developing and testing a method supporting participatory design process with a use of a design system and Augmented Reality interactive interface. We propose a concept of participatory design where participants can directly interact with architectural knowledge encapsulated in the design system. The proposed concept of participatory design supported with a design system was tested during a workshop conducted in Kaunas, Lithuania. The dedicated design system was created in order to minimize physical interaction between the architect and the users while allowing for customization of design solutions by participants. The design system and the participatory design process were linked with the use of a digital communication interface. The paper is concluded with a critical view on the process. The conclusions are based substantially on the results of a survey prepared by the authors and conducted among workshop's participant.

summary	The expansion of urbanization leads to significant changes in land use, consequently affecting carbon storage. This research aims to investigate the carbon loss due to land use alterations and proposes strategies for mitigation. Utilizing existing land use data from 2017 and 2022, along with simulated data for 2025 generated by an ANN model and Cellular Automata, we identified changes in land use. These changes were then correlated with variations in carbon storage, both gains and losses. Our findings reveal a significant loss of 36,859 metric tons of carbon storage from 2017 to 2022. The projection for 2025 estimates a further reduction, reaching a total loss of 83,409 metric tons. By employing the LISA method, we identified that low-carbon storage zones are concentrated in the southeast region of the research site. By overlaying these zones with areas of carbon storage loss, we pinpointed regions severely affected by carbon depletion. Consequently, we propose that mitigation strategies should be imperatively implemented in these identified areas to counteract the trend of carbon storage loss. This approach offers urban planners a solution to identify areas experiencing carbon storage decline. Moreover, our research methodology provides a novel framework for scholars studying similar carbon issues.

summary	Methods for Tessellating a flat surface with regular or semi-regular patterns of polygons have already been addressed in literature and can be easily parameterized. For the tessellation of curved surfaces using patterns of one or more regular polygons there is not a uniquely defined approach to the problem within the context of architectural research and applications. This paper is focused on the tessellation of curved surfaces with square tiles, where the tessellation pattern consists of four squares with partly overlapping sides. In this study double curvature surfaces were considered first, and subsequently surfaces of more complex geometry such as minimal surfaces. Specifically, a method for the square tessellation of two types of doubly curved surfaces, the spherical and the ellipsoidal, is discussed and presented in the paper. In addition, the square tessellation of two types of minimal surfaces, the catenoid and the helicoid, have also been examined and presented. For each one of the surfaces that have been considered, an algorithm that generates the distribution of the planar square surfaces on the surface and renders possible the parametric description of the problem, was developed and presented in the paper. A discussion on boundary conditions for each developed method is also included. The Grasshopper visual programming language has been used for the parametric description and display of the results in a graphic environment. The research discussed in this paper can find application in several real world problems including surface paneling, or space packing of polyhedral structural units on a curved surface.

summary	The relationship between clay manufacturing and architectural design has a long trajectory that has been explored since the early 2000s. From a 3D printing or assembly perspective, using clay in combination with automated processes in architecture to achieve computational design solutions is well established. (Yuan, Leach & Menges, 2018). Craft-based clay art, however, still lacks effective computational design integration. With the improvement of Augmented Reality (AR) technologies (Driscoll et al., 2017) and the appearance of digital platforms, new opportunities to integrate clay manufacturing and computational design have emerged. The concept of digitally transferring crafting skills, using holographic guidance and machine learning, could make clay crafting accessible to more workers while creating the potential to share and exchange digital designs via an open-source manufacturing platform. In this context, this research project explores the potential of integrating computational design and clay crafting using AR. Moreover, it introduces a platform that enables AR guidance and the digital transfer of fabrication skills, allowing even amateur users with no prior making experience to produce complex clay components.
