summary	This paper documents research of a design process that interrelates a single information model to 5-axis, waterjet cutting technology. With the intention of creating an optimized design, data is streamed through a building information model that controls geometry parametrically by a component/system relationship. At the scale of a 4’x8’ panel, material properties and pattern variability act as underlying initiators of design rather than post-rational information. In a manner uncommon to the discipline, the information model is being used as a generative tool, rather than as one for mere documentation. The research assigns a limestone wall type to the panel—a material predominantly used in areas where it is indigenous and typically desirable for its texture, color, and thermal properties. The intention is to develop potentialities through material specificity in the information model’s conceptualization. The water-jet process is then used to erode the limestone to achieve varying fields of scalar voids. In addition, the thickness of wall cladding attenuates for figuration and interest. The final stone panels transition from a rain screen system to a solar screen that modulates light, thereby linking environmental intentions to current technological capabilities. The information model is exported for analysis of daylight and structural dynamic qualities and quantities as part of the workflow. Parameters within the information model database facilitate a dimensionally controlled iterative process. Moreover, fabricating with building materials via the information model expedites a design and makes possible for materiality to move beyond merely conceptual representation.

summary	Innovative technologies that enable more efficient use of energy in the built environment contribute to the effectiveness of green building design, and to sustainable building practices. Digital fabrication can be used to unlock the inherent physical properties of common materials as a means to create solar shades which change shape in response to ambient conditions and user needs in a system which relies on extremely simple mechanical actuation. These conformationally adaptive solar shades take advantage of materials which can be deformed not only to occlude or permit the passage of light, but also to produce optimal angles for the maximization the interception of solar radiation of the surface of the device itself.

summary	Recently, prototyping enabled by CNC technology has found its way into design practice where concepts can be quickly and economically tested through multiple design iterations that closely approximate the realities of oneto- one construction. This has lead to the promise of renewed research in tectonics and constructional techniques where the traditional concepts of craft and the joint, that were once married to the hand, can be rediscovered through the agency of mass customization. If we apply the lineage of the trait—a representational and cognitive tool to marry complex form with the exigencies of construction—pedagogical approaches can be developed that extend the current interest in intricate surface, structural morphology and geometry towards a robust materiality rooted in componentry, the joint, and part-to-whole relationships. This paper will introduce several threads from the twentieth century that have informed these tendencies in contemporary design practice, emerging from the well spring of Viollet-le-Duc. The thesis is supported by undergraduate model-based research employing digital design and fabrication techniques.

title	HYGROSCOPIC CLIMATIC MODULATED BOUNDARIES: A Strategy for Differentiated Performance Using a Natural Circulative and Energy Captive Building Envelope in Hot and Moisture Rich Laden Air Environments
source	Perkins+Will Research Journal, Vol 02.01, 41-53
summary	The operation and construction of buildings account for almost half of the energy use in the United States. To meet global climate change targets, energy consumption of buildings in the long term must be reduced as well as carbon dioxide emissions. This article explores a theoretical building envelope that generates energy and produces water by drawing water vapor out of the air to deliver new sources of water; it lowers indoor humidity in hot and humid climates. The design in this model considers materiality, surface area and environmental conditions to influence build- ing form. The case in this article considers materials and systems application in the design of the building envelope. The hygroscopic building envelope design strategically senses varying conditions of concentration and density of moisture laden air to provide visual indications of its performance. It is a building skin that emulates biological processes by creating pressure differences and transferring energy in various forms.

title	Parametric Sensibility: Cultivating the Material Imagination in Digital Culture
doi	https://doi.org/10.52842/conf.acadia.2010.364
source	ACADIA 10: LIFE in:formation, On Responsive Information and Variations in Architecture [Proceedings of the 30th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-1-4507-3471-4] New York 21-24 October, 2010), pp. 364-371
summary	Digital fabrication and parametric tools require not only digital dexterity but a robust material sensibility that precedes digital mediation. Developed through Gaston Bachelard’s concept of the graft, the material imagination acts as a reciprocal creative intelligence to today’s dominant formal imagination enabled through the fluid geometric precision in digital tools. This paper presents a series of “materials first” pedagogical approaches through which material constraints become operative design criteria in the development of digital skills. This intersection between analog and digital systems develops a parametric sensibility that is demonstrated through physical prototypes and full-scale installations. This approach is implicitly a critique of the disregard of material logic in many parametric approaches in particular, and digital design culture in general. Conversely, the development of a parametric sensibility through analog means enables the development of material primitives from which parametric tools can expand the material imagination while giving structure to it.

title	Generative Design and the Reduction of Presence
source	CAAD - Cities - Sustainability [5th International Conference Proceedings of the Arab Society for Computer Aided Architectural Design (ASCAAD 2010 / ISBN 978-1-907349-02-7], Fez (Morocco), 19-21 October 2010, pp. 97-106
summary	Digital design/fabrication is slowly emancipating architectural design from its traditional static/representational role and endowing it instead with a new, generative function. In opposition to the classical isomorphism between drawings and buildings, wherein the second stand as translations of the first, the digital design/fabrication scenario does not strictly fall within a semiotic frame as much as within a quasi biological context, reminiscent of the Aristotelian notion of entelechy. For the digital data does not represent the building as much it actively works to become the building itself. Only upon sending a given file to a machine does the building begin to materialize as an empirical reality, And eventually a habitable space as we empirically know it. And until the digital data actualizes itself, the building qua building is no more than one single, potential possibility among many others. This new universe of digital design/fabrication does not only cause buildings to be produced as quick, precise, multiply-generated objects but also reduces their presence as original entities. Like cars and fashion items, built structures will soon be manufactured as routinely-consumed items that would look original only through the subtle mechanisms of flexibility: frequent alteration of prototype design (Style 2010, Style 2015..) and “perpetual profiling” (mine, yours, hers,..). The generic will necessarily take over the circumstantial. But this truth will be veiled since “customized prototypes” will be produced or altered to individual or personal specifications. This implies that certain “myths” have to be generated to speed up consumption, to stimulate excessive use and to lock people into a continuous system which can generate consumption through a vocabulary of interchangeable, layered and repeatable functions. Samples of “next season’s buildings” will be displayed and disseminated to enforce this strategy of stimulating and channeling desire. A degree of manipulation is involved, and the consumer is flattered into believing that his or her own free assessment of and choice between the options on offer will lead him or her to select the product the advertiser is seeking to sell. From the standpoint of the architect as a maker, the rising upsurge of digital design and fabrication could leave us mourning the loss of what has been a personal stomping ground, namely the intensity of the directly lived experiences of design and building. The direct, sensuous contact with drawings, models and materials is now being lost to a (digital) realm whose attributes refer to physical reality only remotely. Unlike (analogue) drawings and buildings, digital manipulations and prototypes do not exercise themselves in a real space, and are not subjected in the most rigorous way to spatial information. They denote in this sense a loss of immediacy and a withering of corporal thought. This flexible production of space and the consequent loss of immediate experience from the part of the designer will be analyzed within a theoretical framework underpinned mainly by the works of Walter Benjamin. Samples of digitally-produced objects will be used to illustrate this argument.

title	Material Information: Integrating Material Characteristics and Behavior in Computational Design for Performative Wood Construction
doi	https://doi.org/10.52842/conf.acadia.2010.151
source	ACADIA 10: LIFE in:formation, On Responsive Information and Variations in Architecture [Proceedings of the 30th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-1-4507-3471-4] New York 21-24 October, 2010), pp. 151-158
summary	Architecture as a material practice is still predominantly based on design approaches that are characterized by a hierarchical relationship that prioritizes the generation of geometric information for the description of architectural systems and elements over material specific information. Thus, in the early design stage, the material’s innate characteristics and inherent capacities remain largely unconsidered. This is particularly evident in the way wood constructions are designed today. In comparison to most construction materials that are industrially produced and thus relatively homogeneous and isotropic, wood is profoundly different in that it is a naturally grown biological tissue with a highly differentiated material makeup . This paper will present research investigating how the transition from currently predominant modes of representational Computer Aided Design to algorithmic Computational Design allows for a significant change in employing wood’s complex anisotropic behaviour, resulting from its differentiated anatomical structure. In computational design, the relation between procedural formation, driving information, and ensuing form, enables the systematic integration of material information. This materially informed computational design processes will be explained through two research projects and the resultant prototype structures. The first project shows how an information feedback between material properties, system behaviour, the generative computational process, and robotic manufacturing allows for unfolding material-specific gestalt and tapping into the performative potential of wood. The second project focuses on embedding the unique material information and anatomical features of individual wooden elements in a continuous scanning, computational design and digital fabrication process, and thus introduces novel ways of integrating the biological variability and natural irregularities of wood in architectural design.

summary	Current developments in design-to-production workflows aim to allow architects to quickly prototype designs that result from advanced design processes while also embedding the constraints imposed by selected fabrication equipment. However, the enduring physical separation between design space and fabrication space, together with a continuous approach to both design, via NURBs modeling software, and fabrication, through irreversible material processing methods, limit the possibilities to extend the advantages of a “digital” approach (Ward 2010), such as full editability and reversibility, to physical realizations. In response to such issues, this paper proposes a processto allow the concurrent design and fabrication of discrete structures in a collaborative process between human designer and a 6-axis robotic arm. This requires the development of design and materialization procedures for discrete aggregations, including the modeling of assembly constraints, as well as the establishment of a communication platform between human and machine actors. This intends to offer methods to increase the accessibility of discrete design methodologies, as well as to hint at possibilities for overcoming the division between design and manufacturing (Carpo 2011; Bard et al. 2014), thus allowing intuitive design decisions to be integrated directly within assembly processes (Johns 2014).

summary	This paper will examine the recent transformations to architectural drawing that are occurring in the presence :abstract of information based drawing procedures and their potential for new fabrication methods. The mathematical organization of information has resulted in a more systemic, intricate, and variable approach toward making things— characteristics that have historically been associated with manual forms of craft. The shift from a geometric to an information based paradigm is allowing a wide range of industries to more easily converge. Consequently, a much broader range of interdisciplinary fabrication processes are now available to architects and designers. This confluence of numerical based machinery in other fields is providing new possibilities for architects to visualize data using a broader range of materials and techniques.

summary	Modern materialization of architecture depends on the use of regularized, highly processed remotely - sourced materials produced through a centralized, industrialized process. This involves energy use, increasing the environmental impact and cost of the final structure. This study investigates leveraging digital technology to capture near - site material geometry, providing design tools and processing the material on - site. Optimization techniques are applied to minimize the use and processing of materials while meeting design goals and engineering constraints. A simulation and prototype using digitally selected and cut trees as main bearing members in a structure is used to confirm the proposed process.

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.

summary	Considering mathematical knowledge as an artefact that mediates social activities in the world, this paper emphasizes the contribution of visual thinking to mathematics education and extends it to the learning of design activities, especially in architectural contexts. Results from a previous research paper on architectural design, which focused on the work of some contemporary architects in their day - to - day office activities, showed the relevance of drawing in architectural practice. These results aroused our interest in researching the mediating role of drawing and its structuring effects on creative processes and design activities in architecture.

title	'GHShot': a collaborative and distributed visual version control for Grasshopper parametric programming

summary	When working with parametric models, architects typically focus on using rather structuring them (Woodbury, 2010). As a result, increasing design complexity typically means a convoluted parametric model, amplifying known problems: 'hard to understand, modify, share and reuse' (Smith 2007; Davis 2011). This practice is in contrast with conventional software-programming where programmers are known to meticulously document and structure their code with versioning tool. In this paper, we argue that versioning tools could help to manage parametric modelling complexity, as it has been showing with software counterparts. Four key features of version control: committing, differentiating, branching, and merging, and how they could be implemented in a parametric design practice are discussed. Initial user test sessions with 5 student designers using GHShot Grasshopper version control plugin (Cristie and Joyce 2018, 2017) revealed that the plugin is useful to record and overview design progression, share model, and provide a fallback mechanism.

title	The New Structuralism: Conceptual Mapping of Emerging Key Concepts in Theory and Praxis
source	International Journal of Architectural Computing vol. 8 - no. 4, p. 419
summary	The New Structuralism focuses upon the potential of novel design processes to return architecture to its material sources. A theoretical research presents how the structuring, encoding, and fabricating of material systems are contributing to a new material practice which demands a theoretical foundation comprehensive enough to integrate emerging theories, methods and technologies in design. Selected research works supports shared geometrical, structural and manufacturing representations and processes relevant to The New Structuralism are selected and reviewed. DDNET (Digital Design NETwork) is proposed as a conceptual structure which attempts to relate the body of these findings with theoretical constructs such as key concepts, models, techniques, technologies and leading precedents associated with The New Structuralism.

summary	Music and architecture share not only phenomenological similarities in relation to their characteristics - like volume, timbre, tone pitch, instrumentation vs. geometry, materiality, light ambiance or perspective - but imply as well comparability in the process of creation. The investigation of digital tools that cross borders between music and architecture was the starting point for the research project „Mixer Modeling“. Against this background the paper discusses the transformation of a musical composition controller into an intuitive design tool for the generation of architectural geometries. In the same amount that the use of a MIDI-controller increases the degrees of freedom for the simultaneous activation of various parameters the definition of geometric dependencies on the level of visual programming become more important for the resulting geometry.

summary	Interactive architecture is a fairly recent phenomenon enabled through new materials and technologies. Through experimentation architects are coping with questions of changeability, adaptability, and interaction. However, there are no comprehensive design methods to support this type of architecture. In this paper we aim to bring together methods that can support the design of interactive architecture. The methods are ordered in a methodological framework that provides an overview of possible approaches.

title	Assessing innovation in hybrid designs using shape grammars

summary	Al-kazzaz et al (2010) described hybrid adaption technique to generate innovative designs from heterogeneous precedents using shape grammars. An evaluation of the degree of innovation in the hybrid designs gave feedback to grammar users before and after applying a rule. Innovation was assessed using variables derived from the internal structure of the grammar such as: the number of antecedents in the corpus having the same rule; the number of rules in a subclass rule set having the same geometry; etc. However, the validity of the innovation assessment was unclear and the use of the feedback measures was not demonstrated. Accordingly, this study aims to verify the credibility of the innovation measures and to identify the independent variables that a user can control to achieve a significant impact on each innovation measure as a dependent variable.

summary	This paper describes a new methodology of deriving innovative hybrid designs using shape grammars of heterogeneous designs. The method is detailed within three phases of shape grammars: analysis, synthesis and evaluation. In the analysis phase, the research suggests that original rules of each design component are grouped in subclass rule sets to facilitate rule choices. Additionally, adding new hybrid rules to original rules expands the options available to the grammar user. In the synthesis phase, the research adopts state labels and markers to drive the design generation. The former is implemented with a user guide grammar to ensure hybridity in the generated design, while the latter aims to ensure feasible designs. Lastly evaluation criteria are added to measure the degree of innovation of the hybrid designs. This paper describes the derivation of hybrid minaret designs from a corpus of heterogeneous traditional minaret designs.

title	Embedded Rationality: A Unified Simulation Framework for Interactive Form Finding
source	International Journal of Architectural Computing vol. 8 - no. 4, p. 39
summary	This paper describes embedded rationality as a method for implicitly combining fabrication constraints into an interactive framework for conceptual design. While the concept of ‘embedded rationality’ has been previously discussed in the context of a parametric design environment, we employ this concept to present a novel framework for dynamic simulation as a method for interactive form-finding. By identifying categories of computational characteristics, we present a unified physics-solver that generalizes existing simulations through a constraint-based approach. Through several examples we explore conceptual approaches to a fixed form where the resulting effects of interacting forces are produced in real-time. Finally, we provide an example of embedded rationality by examining a constraint-based model of fabrication rationale for a Planar Offset Quad (POQ) panelization system.

summary	The recent developments in digital technologies and contemporary design tools are initiating new approaches of form-finding based on parametric development of multiple geometries with simultaneous consideration of various aspects. This paper focuses on the use of advanced parametric CAD systems and reformulated construction logics to enhance the potential and possibilities of form finding processes. This approach is exemplified through the “Greenhouse Trauttmansdorff project”. The project demonstrates a form finding approach which is based on defined parameters that not only fulfil aesthetic and functional aspects, but simultaneously take structural properties and the resulting sun shading behaviour into account. We will explore within this paper how – next to the functional and contextual building requirements – required illumination levels inside the greenhouse create a feedback loop between the structural system and its cladding system.
