title	Heuristic Optimization in Design

summary	This paper presents a workflow called the ‘heuristic optimization workflow’ that integrates Octopus, a Multi-Objective Optimization (MOO) engine with Grasshopper3D, a parametric modeling tool, and multiple simulation software. It describes a process that enables the designer to integrate disparate domains via Octopus and complete a feedback loop with the developed interactive, real-time visualization tools. A retrospective design of the Bow Tower in Calgary is used as a test case to study the impact of the developed workflow and tools, as well as the impact of MOO on the performance of the solutions. The overall workflow makes MOO based results more accessible to designers and encourages a more interactive ‘heuristic’ exploration of various geometric and topological trajectories. The workflow also reduces design decision uncertainty and design cycle latency through the incorporation of a feedback loop between geometric models and their associated quantitative data. It is through the juxtaposition of extreme performing solutions that serendipity is created and the potential for better multiple performing solutions is increased.es responsive systems, which focus on the implementation of multi-objective adaptive design prototypes from sensored environments. The intention of the work is to investigate multi-objective criteria both as a material system and as a processing system by creating prototypes with structural integrity, where the thermal energy flow through the prototype, to be understood as a membrane, can be controlled and the visual transparency altered. The work shows performance based feedback systems and physical prototype models driven by information streaming, screening, and application.

title	Protocol of Error: The design and construction of a bending-active gridshell from natural bamboo
doi	https://doi.org/10.52842/conf.caadria.2016.415
source	Living Systems and Micro-Utopias: Towards Continuous Designing, Proceedings of the 21st International Conference on Computer-Aided Architectural Design Research in Asia (CAADRIA 2016) / Melbourne 30 March–2 April 2016, pp. 415-424
summary	This paper advocates alternative methods to overcome the impossibility of realising ‘perfect’ digital designs. It discusses Hong Kong’s 2015 ‘ZCB Bamboo Pavilion’ as a methodological case study for the design and construction of architecture from unprocessed natu- ral bamboo. The paper critically evaluates protocols set up to deal with errors resulting from precise digital design systems merging with inconsistent natural resources and onsite craftsmanship. The paper starts with the geometric and tectonic description of the project, illus- trating a complex and restrictive construction context. Bamboo’s unique growth pattern, structural build-up and suitability as a bending- active material are discussed and Cantonese bamboo scaffolding craftsmanship is addressed as a starting point for the project. The pa- per covers protocols, construction drawings and assembly methods developed to allow for the incorporation and of large building toler- ances and dimensional variation of bamboo. The final as-built 3d scanned structure is compared with the original digital model. The pa- per concludes by discussing the necessity of computational architec- tural design to proactively operate within a field of real-world inde- terminacy, to focus on the development of protocols that deal with imperfections, and to redirect design from the virtual world towards the latent opportunities of the physical.

title	Phototropism of Tensile Façade System through Material Agency
doi	https://doi.org/10.52842/conf.caadria.2015.127
source	Emerging Experience in Past, Present and Future of Digital Architecture, Proceedings of the 20th International Conference of the Association for Computer-Aided Architectural Design Research in Asia (CAADRIA 2015) / Daegu 20-22 May 2015, pp. 127-136
summary	This paper researches material agencies, mechanical systems and façade designs that are able to respond to environmental changes through local interactions, inspired by biological systems. These are based on a model of distributed intelligence founded on plants and animal collectives, from which intelligent behavior emerges through simple local associations. Biological collective systems integrate material form and responsiveness and have the potential to inform new architectural and engineering strategies. The design approach of this research is based on a data-driven methodology spanning from design inception to simulation and physical modeling. Data-driven models, common in the fields of natural science, offer a method to generate and test a multiplicity of responsive solutions. The driving concepts are three types of evolutionary adaptation: flexibility, acclimation, and learning. The proposed façade system is a responsive textile shading structure which uses integrated actuators that moderate their local environments through simple interactions with their immediate neighbors. Computational techniques coupled to material logics create an integral design framework leading to heterogeneous environmental and structural conditions, producing local responses to environmental stimuli and ultimately effective performance of the whole system.

title	Digital Fabrication Methods of Composite Architectural Panels for Complex Shaped Buildings
doi	https://doi.org/10.52842/conf.caadria.2015.703
source	Emerging Experience in Past, Present and Future of Digital Architecture, Proceedings of the 20th International Conference of the Association for Computer-Aided Architectural Design Research in Asia (CAADRIA 2015) / Daegu 20-22 May 2015, pp. 703-712
summary	Composite materials have been explored in architecture for their high performance characteristics that allow customization of functional properties of lightness, strength, stiffness and fracture toughness. Particularly, engineering advancements and better understanding of fiber composites have resulted in growing applications for architectural structures and envelopes. As most developments started outside the realm of architecture such as automobile and aeronautical industries, there is need to advance knowledge in architectural design to take advantage of this new technology. In this paper, the authors introduce preliminary results of new digitally driven fabrication methods for fiber-reinforced composite sandwich panels for complex shaped buildings. This research examined the material properties, manufacturing methods and fabrication techniques needed to develop a proof of concept system using off-the-shelf production technology that ultimately can be packaged into a containerized facility for on-site panel production. Experiments focused on developing a digitally controlled deformable mold to create composite relief structures for highly customized geometrical façade components. Research findings of production materials, methods, assembly techniques, are discussed to offer insights into novel opportunities for architectural composite panel fabrication and commercialization.

title	Form Follows Flow: A Material-Driven Computational Workflow for Digital Fabrication of Large-Scale Hierarchically Structured Objects
doi	https://doi.org/10.52842/conf.acadia.2015.185
source	ACADIA 2105: Computational Ecologies: Design in the Anthropocene [Proceedings of the 35th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-0-692-53726-8] Cincinnati 19-25 October, 2015), pp. 185-193
summary	In the natural world, biological matter is structured through growth and adaptation, resulting in hierarchically structured forms with tunable material computation. Conventional digital design tools and processes, by contrast, prioritize shape over matter, lacking integration between modeling, analysis, and fabrication. We present a novel computational environment and workflow for the design and additive manufacturing of large-scale hierarchically structured objects. The system, composed by custom multi-barrel deposition attached to robotic positioning, integrates material properties, fabrication constraints and environmental forces to design and construct full-scale architectural components. Such components are physically form-found by digitally extruding natural polymers with functionally graded mechanical and optical properties informed by desired functionality and executed through flow-based fabrication. In this approach, properties such as viscosity, velocity, and pressure embed information in two-dimensional printing patterns and induce three-dimensional shape formation of the fabricated part. As a result, the workflow associates physical material and fabrication constraints to virtual design tools for modeling and analysis, challenging traditional design workflows and prioritizing flow over form.

summary	This applied research brings together the performance analysis of a building's micro-scale and urban-infrastructure's macro-scale. A New York City lot, is serving as the background of experimentation with parametric design, performance simulation, data analysis and visualization. The paper describes the process of integrating design intentions, location parameters, climate data, material properties, and space quality and sustainability metrics into one platform. Although in-depth domain knowledge is irreplaceable, the paper argues that the exploration into contemporary, easily accessible and algorithmic simulation software, provides a unique educational opportunity for architects and students to integrate performance driven design in their every-day practice, and become aware of the consequences of their design on urban infrastructure systems. This allows them to reduce the time frame between design iterations and performance evaluation for the benefit of better informed decisions.

title	Adaptive Pneumatic Shell Structures - Feedback-driven robotic stiffening of inflated extensible membranes and further rigidification for architectural applications
doi	https://doi.org/10.52842/conf.ecaade.2016.1.549
source	Herneoja, Aulikki; Toni Österlund and Piia Markkanen (eds.), Complexity & Simplicity - Proceedings of the 34th eCAADe Conference - Volume 1, University of Oulu, Oulu, Finland, 22-26 August 2016, pp. 549-558
summary	The paper presents the development of a design framework that aims to reduce the complexity of designing and fabricating free-form inflatables structures, which often results in the generation of very complex geometries. In previous research the form-finding potential of actuated and constrained inflatable membranes has already been investigated however without a focus on fabrication (Otto 1979). Consequently, in established design-to-fabrication approaches, complex geometry is typically post-rationalized into smaller parts and are finally fabricated through methods, which need to take into account cutting pattern strategies and material constraints. The design framework developed and presented in this paper aims to transform a complex design process (that always requires further post-rationalization) into a more integrated one that simultaneously unfolds in a physical and digital environment - hence the term cyber-physical (Menges 2015). At a full scale, a flexible material (extensible membrane, e.g. latex) is actuated through inflation and modulated through additive stiffening processes, before being completely rigidified with glass fibers and working as a thin-shell under compression.

Denver. 26-28 October 2023. edited by A. Crawford, N. Diniz, R. Beckett, J. Vanucchi, M. Swackhamer 220-225.
summary	Previous research projects (Adel, Agustynowicz, and Wehrle 2021; Adel Ahmadian 2020; Craney and Adel 2020; Adel et al. 2018; Apolinarska et al. 2016; Helm et al. 2017; Willmann et al. 2015; Oesterle 2009) have explored the use of comprehensive digital design-to-fabrication workflows for the construction of nonstandard timber structures employing robotic assembly technologies. More recently, the Robotically Fabricated Structure (RFS), a bespoke outdoor timber pavilion, demonstrated the potential for highly articulated timber architecture using short timber elements and human-robot collaborative assembly (HRCA) (Adel 2022). In the developed HRCA process, a human operator and a human fabricator work alongside industrial robotic arms in a shared working environment, enabling collaborative fabrication approaches. Building upon this research, we present an exploration adapting HRCA to nail-laminated timber (NLT) fabrication, demonstrated through a case study exhibition (Figures 1 and 2).

summary	With the comprehensive integration of software-based tools in actual processes of design development and fabrication, the boundaries between design and production become increasingly blurred. The methodology of the process of creation changes: the design development phase reaches up to the last produced model in a product series, in the same time the serial production cycle already starts with the first prototype.The aim of this research project is to explore and show the re-strengthening link between form, function, material and fabrication particularly driven by raising prominence of digital tools for design and production. Hereby the focus is on two points: the implementation of user data/input in the light of 'Open Innovation' as driver of form and function on one hand and the crafing inspired aproach of a comprehensive integration of material properties, behaviour tradional techniques of processing into the the design process.

title	Gradient Transparency: Marine Animals As a Source of Inspiration. - Exploring Material Bio-Mimicry through the Latest 3D Printing Technology in Architectural surfaces
doi	https://doi.org/10.52842/conf.ecaade.2015.2.325
source	Martens, B, Wurzer, G, Grasl T, Lorenz, WE and Schaffranek, R (eds.), Real Time - Proceedings of the 33rd eCAADe Conference - Volume 2, Vienna University of Technology, Vienna, Austria, 16-18 September 2015, pp. 325-330
summary	Digital fabrication technologies are changing rapidly the way we design, as any other tool would affect the way we produce space. Multi layered 3D printing is already allowing architects, designers and engineers to experiment with new design processes and new ways of production. At the same time, little research has being done in the way gradient transparency (through multiple layered surfaces) can affect the design process through computation; a field that deserves further investigation. The focus of this paper is to explore bio-inspired material finding design processes while combining biology, architecture and material science. We explore performance driven design possibilities through a study of marine animals -and specifically cephalopods- where opacity between skin layers is controlled through color pigments - while black pigments are called melanophores - which is often used as a type of camouflage. We propose a computation model that follows the logic of gradient transparency through pigments to fit complex “host surfaces”. We define a “host” surface as a basic geometry on which the pigments are computed. This study provides the methodology for the design of biomimetic surfaces with gradient transparency, using controlled and computated sub geometries analogous to the melanophores pigments. We finally propose Pigment Skin, a computational design model as an example to materialize this study.

title	The Use of Digital Fabrication as a Sketching Tool in the Architectural Design Process - A Case Study
doi	https://doi.org/10.52842/conf.ecaade.2015.2.319
source	Martens, B, Wurzer, G, Grasl T, Lorenz, WE and Schaffranek, R (eds.), Real Time - Proceedings of the 33rd eCAADe Conference - Volume 2, Vienna University of Technology, Vienna, Austria, 16-18 September 2015, pp. 319-324
summary	Computer-aided manufacturing (CAM) technologies including computer numerically controlled (CNC) milling, laser cutting and 3D printing are becoming cheaper and globally more accessible. Accordingly, many design professionals, academics and students have been able to experience the benefits and challenges of using digital fabrication in their designs. The use of digital fabrication in the education of architecture students has become normal in many schools of architecture, and there is a growing demand for computer-aided manufacturing (CAM) logic and fabrication knowledge in student learning. Clearly, architecture students are acquiring material base-thinking, time management, production methods and various software skills through this digital fabrication. However, it appears to be the case that architecture students use digital fabrication mainly in the final stage of their design or in their finishing work. In this study, computer-aided manufacturing (CAM) technologies have been used as a sketch tool rather than simply for fabricating a final product in the architectural design process and the advantages of this educational practice are demonstrated.

summary	The Klimasymmetry research project is part of ongoing investigations that ask how the design of a surface emanating radiant heating and cooling can influence the non-visual spatial boundaries created by asymmetrical thermal conditions. This research investigates the nature of the surface as an initiator of a thermal environment in an attempt to locate thermal tactility and the spatial perception according to radiant heat transfer. Surface qualities such as the quantity of area and thermal capacity of the material affects the ability of the panel to emit or absorb electromagnetic radiation, informing the geometry, topography, and location of each panel relative to the human body.

summary	This paper studies the architectural potential of the implementation of material feedback using computer vision before and during an automated fabrication process. The combination of an industrial robot and a 3D camera is used expand the typical one-way design and fabrication process (from a digital design to a physical output), to a feedback loop, where specific material information becomes the main trigger of design decisions and fabrication processes.

title	Spatial Nets: the Computational and Material Study of Reticular Geometries
doi	https://doi.org/10.52842/conf.acadia.2015.123
source	ACADIA 2105: Computational Ecologies: Design in the Anthropocene [Proceedings of the 35th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-0-692-53726-8] Cincinnati 19-25 October, 2015), pp. 123-135
summary	Reticular systems are in many aspects a distinct taxonomy of volumetric geometries. In comparison with the conventional embodiment of a ‘volume’ that encapsulates a certain quantity of space with a shell reticular geometries emerge from the accumulation of micro elements to define a gradient of space. Observed in biological systems, such structures result from their material properties and formation processes as well as often ‘simple’ axioms that produce complex results. In micro or macro levels, from forest tree canopies to plant cell walls these porous volumes are not shaped to have a singular ‘solution’ for a purpose; they provide the fundamental geometric characteristics of a ‘line cloud’ that is simultaneously flexible in response to its environment, porous to other systems (light, air, liquids) and less susceptible to critical damage. The porosity of such systems and their volumetric depth also result in kinetic spatial qualities in a 4D architectural space. Built upon a ‘weaving’ organization and the high performance material properties of carbon fiber composite, this research focuses on a formal grammar that initiates the complex system of a reticular volume. A finite ‘lexical’ axiom is consisted of the basic characters of H, M and L responding to the anchor points on the highest, medium and lower levels of the extruding loom. The genome thus produces a string of data that in the second phase of programming are assigned to 624 points on the loom. The code aims to distribute the nodes across the flat line cloud and organize the sequence for the purpose of overlapping the tensioned strings. The virtually infinite results are then assessed through an evolutionary solver for confining an array of favorable results that can be then selected from by the designer. This research focuses on an approximate control over the fundamental geometric characteristics of a reticular system such as node density and directionality. The proposal frames the favorable result of the weave to be three-dimensional and volumetric – avoiding distinctly linear or surface formations.

summary	In this study, we revisit the concepts of abstraction and materialization with regards to the theoretical framework of new materialism. Underlining the changing relationship between design through abstraction (DtA) and design through materialization (DtM) in design history, we propose an integration of the two towards achieving design emergence. Additional to a theoretical framework, we provide a showcase through material experiments of plaster and abstractions in the form of shape computation. We discuss results as parameters for future digital implementations and potentials for design practice and education.

title	Toward a Behavioral Design System: An Agent-Based Approach for Polygonal Surfaces Structures
doi	https://doi.org/10.52842/conf.acadia.2015.161
source	ACADIA 2105: Computational Ecologies: Design in the Anthropocene [Proceedings of the 35th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-0-692-53726-8] Cincinnati 19-25 October, 2015), pp. 161-172
summary	The following research investigates the development of an agent-based design method as an integrative design tool for polygonal surface structures. The aim of this research is to develop a computational tool that self-organizes the emergence of polygonal surface structures from interaction between its constitutive lattices. This research focuses on the ethological level of morphogenesis that is relevant to the animal or insect societies, whereby agents mediate the material organizations with environmental aspects. Meanwhile, behavior-based approaches are investigated as a bottom-up system to develop a computational framework in which the lower-level features constantly interact. The lower-level features such as material properties (e.g., geometric descriptions) are abstracted into building blocks or agents to construct the agent’s morphology. The abstracted principles, which define the agent’s morphology, are aggregated into a generative tool to explore the emergent complexities. This exploration coupled with the generative constraint mechanisms steers the collective agents system toward the cloud of solutions; hence, the collective behaviors of agents constitute the polygonal surface structures. This polygonal system is a bottom up approach of developing the complex surface that emerges through topological and topographical interaction between cells and their surrounding environment. Subsequently, the integrative system is developed through agent-based parametric modelling, in which the knowledge-based system as a top-down approach is substituted with the agent system together with its morphological features and significant behaviors.

title	Towards A Motion Grammar for Robotic Stereotomy

summary	This paper presents progress towards the definition of a motion grammar for robotic stereotomy. It describes a vocabulary of motions able to generate complex forms by cutting, slicing, and/or carving 3-D blocks of material using a robotic arm and a custom made cutting tool. While shape grammars usually deal with graphical descriptions of designs, a motion grammar seeks to address the 3-D harmonic movements of machine, tool, and material substrate choreographically, suggesting motion as a generative vehicle of exploration in both designing and making. Several models and prototypes are presented and discussed.

title	Alternative Fabrication Process for Free-Form FRP Architectural Elements Relying on Fabric Materiality Towards Freedom from Molds and Surface Articulation
source	The next city - New technologies and the future of the built environment [16th International Conference CAAD Futures 2015. Sao Paulo, July 8-10, 2015. Electronic Proceedings/ ISBN 978-85-85783-53-2] Sao Paulo, Brazil, July 8-10, 2015, pp. 397-410.
summary	FRP (fiber reinforced polymers) is a family of composite materials combining fibers and polymers to offer exceptional mechanical properties. Its unique material properties have led to its wide application across industries. Although we witness a growing interest in the material in the architectural field in recent years, a significant barrier to its application lies in the need for a mold. The paper describes a new alternative fabrication process for architectural FRP elements that relies on fabric materiality. It suggests a mold free process, combining form finding and garment making techniques, to allow for complex morphologies, surface articulation and variation. The paper describes both the fabrication process through physical experiments, as well as the design process through the use of two design software tools. It demonstrates the potential for sustainable variation of large component facade system.

title	Structural design based on performance applied to development of a lattice wind tower
source	The next city - New technologies and the future of the built environment [16th International Conference CAAD Futures 2015. Sao Paulo, July 8-10, 2015. Electronic Proceedings/ ISBN 978-85-85783-53-2] Sao Paulo, Brazil, July 8-10, 2015, pp. 326.
summary	This paper studies the process of parametric and algorithmic design, integrating structural analysis and design for the generation of complex geometric structures. This methodology is based on the Performative Model, where the shape is generated using performance criteria. In the approach, the development of complex structures is only possible by reversing the process of thinking to generate the form with established parameters for geometry, material and loading aspects. Thus, the structural engineer no longer only participates in the evaluation phase but also appears in the early stages, creating a process of exploration and production of common knowledge among architects and engineers. To research performance-based design, the development of a conceptual lattice for a wind tower is proposed. Thus, a system is made to generate geometries using Rhinoceros software, the Grasshopper plugin, and the VB programming language, integrated with stress analysis through the Scan & Solve plugin.

title	The exploration of the projetual world of the building blocks through the interactive digital game Minecraft
source	SIGRADI 2015 [Proceedings of the 19th Conference of the Iberoamerican Society of Digital Graphics - vol. 1 - ISBN: 978-85-8039-135-0] Florianópolis, SC, Brasil 23-27 November 2015, pp. 371-377.
summary	This article proposes a reflection on the possibilities of using games that explore architectural design world of building blocks applied to the universe of Architecture and Urbanism design, both from a literature search and through empirical data collected from a workshop coordinated by the Research Group of Languages and Expressions of Architecture, Urbanism and Design. The objective is to highlight the possibilities and limitations of using the projetual world of building blocks as an academic material for Architecture and Urbanism, especially after the experience of the interactive game Minecraft based on the Grammar Shape.
