title	Computer-Aided Design and Manufacturing of Complex Shaped Concrete Formwork
source	Doctor of Design Thesis, Graduate School of Design, Harvard University, Cambridge, MA
summary	The research presented in this thesis challenges the appropriateness of existing, conventional forming practices in the building construction industry--both in situ or in prefabrication--for building concrete "freeforms," as they are characterized by impracticality and limitations in achieved geometric/formal quality. The author's theory proposes the application of alternative, non-traditional construction methods derived from the integration of information technology, in the form of Computer-Aided Design (CAD), Engineering (CAE) and Manufacturing (CAM), into the concrete tooling and placing process. This concept relies on a descriptive shape model of a physically non-existent building element which serves as a central database containing all the geometric data necessary to completely and accurately inform design development activities as well as the construction process. For this purpose, the thesis orients itself on existing, functioning models in manufacturing engineering and explores the broad spectrum of computer-aided manufacturing techniques applied in this industry. A two-phase, combined method study is applied to support the theory. Part I introduces the phenomenon of "complexity" in the architectural field, defines the goal of the thesis research and gives examples of complex shape. It also presents the two analyzed technologies: concrete tooling and automation technology. For both, it establishes terminology, classifications, gives insight into the state-of-the-art, and describes limitations. For concrete tooling it develops a set of quality criteria. Part II develops a theory in the form of a series of proposed "non-traditional" forming processes and concepts that are derived through a synthesis of state-of-the-art automation with current concrete forming and placing techniques, and describes them in varying depth, in both text and graphics, on the basis of their geometric versatility and their appropriateness for the proposed task. Emphasis is given to the newly emerging and most promising Solid Freeform Fabrication processes, and within this area, to laser-curing technology. The feasibility of using computer-aided formwork design, and computer-aided formwork fabrication in today's standard building practices is evaluated for this particular technology on the basis of case-studies. Performance in the categories of process, material, product, lead time and economy is analyzed over the complete tooling cycle and is compared to the performance of existing, conventional forming systems for steel, wood, plywood veneer and glassfiber reinforced plastic; value s added to the construction process and/or to the formwork product through information technology are pointed out and become part of the evaluation. For this purpose, an analytical framework was developed for testing the performance of various Solid Freeform Fabrication processes as well as the "sensitivity," or the impact of various influencing processes and/or product parameters on lead time and economy. This tool allows us to make various suggestions for optimization as well as to formulate recommendations and guidelines for the implementation of this technology. The primary objective of this research is to offer architects and engineers unprecedented independence from planar, orthogonal building geometry, in the realization of design ideas and/or design requirements for concrete structures and/or their components. The interplay between process-oriented design and innovative implementation technology may ultimately lead to an architecture conceived on a different level of complexity, with an extended form-vocabulary and of high quality.

summary	The hybridization of architectural, biological and robotic agencies Situated in the field of architectural biodesign, InterspeciesForms explores a closer relationship between the fungus Pleurotus ostreatus and the designer in the creation of form. The intention of hybridizing mycelia’s agency of growth with architectural design intention is to generate novel, non-indexical crossbred designed outcomes that evolve preconceived notions of architectural form. Mycelium are threadlike fibrous root systems made up of hyphae, that form the vegetative part of a fungus (Jones 2020). Known as the hackers of the wood wide web (Simard 1997) mycelia form complex symbiotic relationships with other species that inhabit our earth. Michael Lim states “Fungi redefine resourcefulness, collaboration, resilience and symbiosis” (Lim 2022, p. 14). When wandering around the forest to connect with other species or searching for food, fungi form elaborate and entangled networks by spreading their hyphal tips. Shown in Figure 1, this living labyrinth results in the aesthetic formation of an intricate web. Due to the organisms ability to determine the most effective direction of growth, communicate with its surrounding ecosystem, and connect with other species, fungi are indeed an intelligent species with a unique aesthetic that must not be ignored. In drawing on these concepts, I refer to the organism’s ability to search for, tangle, and digest its surroundings as ‘mycelia agency of growth’. It is this specific behavioral characteristic that is the focus of this research, with which I, as the architect, set out to co-create and hybridize with.

title	Hierarchical Decomposition of Architectural Computer Models
doi	https://doi.org/10.52842/conf.caadria.1997.197
source	CAADRIA ‘97 [Proceedings of the Second Conference on Computer Aided Architectural Design Research in Asia / ISBN 957-575-057-8] Taiwan 17-19 April 1997, pp. 197-203
summary	Architectural models can be represented in a hierarchy of complexity. Higher level or more complex architecture structures are then designed by repetitively instantiating libraries of building blocks. The advantages are that the object can be achieved in modular fashion and any modification to the definition of a building block can be easily propagated to all higher level objects using the block. Unfortunately, many existing representations of architectural models are monolithic instead of hierarchical and modular, thus, making the reuse of models very difficult and inefficient. This paper describes a research project on developing a tool to decompose a monolithic architectural model into elementary building blocks and then create a hierarchy in the model representation. The tool provides a graphical interface for the visualization of a model and a cutting plane. An associated algorithm will then automatically detach parts of the model into building blocks depending on where the user is applying the cutting plane. Studies will also be made on dividing more complex models employing spherical and NURBS surfaces.

title	A Virtual Reality Building Block Composer for Architecture
doi	https://doi.org/10.52842/conf.caadria.1997.051
source	CAADRIA ‘97 [Proceedings of the Second Conference on Computer Aided Architectural Design Research in Asia / ISBN 957-575-057-8] Taiwan 17-19 April 1997, pp. 51-59
summary	Design is a complex and time consuming process. One way to simplify the design process is to use pre-build blocks for commonly known parts instead of creating them again with CAD. To give the designer an immediate 3D view of the design, designing in virtual reality is a good choice. This paper presents a virtual reality interface tool which allows a user to assemble an architecture structure from a library of pre-built blocks. The library is a distributed client-server database.

title	Architectural Design Based on Parametric Variation and Associative Geometry
doi	https://doi.org/10.52842/conf.ecaade.1997.x.h5q
source	Challenges of the Future [15th eCAADe Conference Proceedings / ISBN 0-9523687-3-0] Vienna (Austria) 17-20 September 1997
summary	This paper considers the role of the computer for detailed design within the wider architectural design process. The central proposition is that parametric modelling software is invaluable for both preliminary and developed design where there is a need for the definition, manipulation and visualisation of complex geometry. The paper begins with a definition of 'parametric design' followed by a consideration of its potential to assist or hinder the designer. A worked example will demonstrate how the elements that make up a model can be referenced to each other using a number of clearly defined constraints, the completed model being changed, modified and regenerated while conforming to pre-set conditions. This will be followed by a report on research into the implications of parametric design modelling applied retrospectively to Jørn Utzon's documented design process for the Sydney Opera House. The study analyses how conventional modelling coped with the manipulation of these forms and compares this with the potential of computer-aided iterative design refinement.

title	Open-source, parametric architecture to propagate hyper-dense, sustainable urban communities: parametric urban dwellings for the experience economy
doi	https://doi.org/10.52842/conf.caadria.2010.443
source	Proceedings of the 15th International Conference on Computer Aided Architectural Design Research in Asia / Hong Kong 7-10 April 2010, pp. 443-452
summary	Rapid developments in societal, technological, and natural systems suggest profound changes ahead if research in panarchical systems (Holling, 2001) is to be believed. Panarchy suggests that systems, both natural and man-made, rise to the point of vulnerability then fail due to disruptive forces in a process of ‘creative destruction.’ This sequence allows for radical, and often unpredictable, renewal. Pressing sustainability concerns, burgeoning urban growth, and emergent ‘green manufacturing’ laws, suggest that future urban dwellings are headed toward Gladwell’s ‘tipping point’ (2002). Hyper-dense, sustainable, urban communities that employ open-source standards, parametric software, and web-based configurators are the new frontier for venerable visions. Open-source standards will permit the design, manufacture, and sale of highly diverse, inter-operable components to create compact urban living environments that are technologically sophisticated, sustainable, and mobile. These mass-customised dwellings, akin to branded consumer goods, will address previous shortcomings for prefabricated, mobile dwellings by stimulating consumer desire in ways that extend the arguments of both Joseph Pine (1992) and Anna Klingman (2007). Arguments presented by authors Makimoto and Manners (1997) – which assert that the adoption of digital and mobile technologies will create large-scale societal shifts – will be extended with several solutions proposed.

title	Teaching CAD with Language Learning Methods
doi	https://doi.org/10.52842/conf.acadia.1997.173
source	Design and Representation [ACADIA ‘97 Conference Proceedings / ISBN 1-880250-06-3] Cincinatti, Ohio (USA) 3-5 October 1997, pp. 173-188
summary	By looking at computer aided design as design communication we can use pedagogical methods from the well-developed discipline of language learning. Language learning breaks down a complex field into attainable steps, showing how learning strategies and attitudes can enhance mastery. Balancing the linguistic emphases of organizational analysis, communicative intent and contextual application can address different learning styles. Guiding students in learning approaches from language study will equip them to deal with constantly changing technology. From overall curriculum planning to specific exercises, language study provides a model for building a learner-centered education. Educating students about the learning process, such as the variety of metacognitive, cognitive and social/affective strategies can improve learning. At an introductory level, providing a conceptual framework and enhancing resource-finding, brainstorming and coping abilities can lead to threshold competence. Using kit-of-parts problems helps students to focus on technique and content in successive steps, with mimetic and generative work appealing to different learning styles. Practicing learning strategies on realistic projects hones the ability to connect concepts to actual situations, drawing on resource-usage, task management, and problem management skills. Including collaborative aspects in these projects provides the motivation of a real audience and while linking academic study to practical concerns. Examples from architectural education illustrate how the approach can be implemented.

summary	Daylight phenomena are dynamic, complex and difficult to capture. Students find that they are hard to study and master. Basically, there are three approaches to the problem: physical modeling, graphic techniques and computation. Most of the students make use of all three channels to solve their design problem, but some of them don’t pay enough attention to the third approach – computation.

title	Matching of freeform curves
source	Computer-Aided Design, Vol. 29 (5) (1997) pp. 369-378
summary	Freeform parametric curves are extensively employed in various fields such as computer graphics, computer vision, robotics, and geometric modeling. While manyapplications exploit and combine univariate freeform entities into more complex forms such as sculptured surfaces, the problem of a fair or even optimal relativeparameterization of freeforms, under some norm, has been rarely considered. In this work, we present a scheme that closely approximates the optimal relativematching between two or even n given freeform curves, under a user's prescribed norm that is based on differential properties of the curves. This matching iscomputed as a reparameterization of n - 1 of the curves that can be applied explicitly using composition. The proposed matching algorithm is completely automaticand has been successfully employed in different applications with several demonstrated herein: metamorphosis of freeform curves with feature preservations, keyframe interpolation for animation, self-intersection free ruled surface construction, and automatic matching of rail curves of blending surfaces.

title	Integration of Sustainable Approaches in the Building Design Process
source	Firenze International Conference for Teachers of Architecture, 16.-18. October 1997, Firenze, Italy
summary	Sustainable approaches in the choice of building components require attentive control of the building design and complex analyses of the behavior of chosen components and their ecological balance. One strategy to support sustainable approaches is the technique of integrated planing. Integrated planing comprises both, horizontal (interdisciplinary teams) and vertical (building life cycle oriented) integration. Its realization requires the ability to view a building under different aspects (e.g. views of domain experts) and at different stages over time (preliminary design, design, construction, operation, demolition). These different views can only be considered at once, if different approaches in various areas such as computer aided design (CAD), modeling (PDM), and cooperation (CORBA) are integrated into one working environment. Over the last decade, the Institut für Industrielle Bauproduktion (ifib), University of Karlsruhe, Germany and the Institut für Kernenergetik und Energiesysteme (IKE), University of Stuttgart (Germany), have investigated various tools and techniques, supporting the implementation of these approaches. Several research projects were subject to experiments in this context.

title	Edge of Chaos. Towards intelligent architecture through distributed control systems based on Cellular Automata.
doi	https://doi.org/10.52842/conf.acadia.2018.226

summary	From the “Edge of Chaos”, a mathematical space discovered by computer scientist Christopher Langton (1997), compelling behaviors originate that exhibit both degrees of organization and instability creating a continuous dance between order and chaos. This paper presents a project intended to make this complex theory tangible through an interactive installation based on metamaterial research which demonstrates emergent behavior using Cellular Automata (CA) techniques, illustrated through sound, light and motion. We present a multi-sensory narrative approach that encourages playful exploration and contemplation on perhaps the biggest questions of how life could emerge from the disorder of the universe. We argue a way of creating intelligent architecture, not through classical Artificial Intelligence (AI), but rather through Artificial Life (ALife), embracing the aesthetic emergent possibilities that can spontaneously arise from this approach. In order to make these ideas of emergent life more tangible we present this paper in four integrated parts, namely: narrative, material, hardware and computation. The Edge of Chaos installation is an explicit realization of creating emergent systems and translating them into an architectural design. Our results demonstrate the effectiveness of a custom CA for maximizing aesthetic impact while minimizing the live time of architectural kinetic elements.

title	Visualisation of Photovoltaic Clad Buildings
source	International Conference on Information Visualisation -IV 97, London, 27-29 August 1997, ISBN 0 8186 8076 8
summary	This paper describes a study carried out to investigate the capabilities of computer aided design software for the visualisation of building elevations and detail, with focus on the representation of photovoltaic cells in facade architecture. The development of photovoltaic (PV) technology, converting energy from sunlight into electricity, has resulted in the emergence of PV as a building material. This has generated much debate on the aesthetic implications of PV integrated buildings. PV introduces a particularly complex set of requirements not present in traditional cladding materials. As well as the physical characteristics of the material, there is a need to consider factors such as orientation to the sun, and shadows cast by neighbouring buildings. Architects, engineers, developers, clients and the general public all need to be able to visualise proposed designs, either of new or refurbished buildings. This study investigates both the process and end results of computer visualisation in the context of photovoltaic clad buildings.

source	CAAD Futures 1997 [Conference Proceedings / ISBN 0-7923-4726-9] München (Germany), 4-6 August 1997, pp. 135-150
summary	ARMILLA5 is a generic computer aided design system, which supports the cooperative design of complex buildings (such as labs, offices or schools) over multiple levels of abstraction. It follows the metaphor of a virtual building site. The designers and engineers meet at a spatial location on the Internet and prepare the building construction by simulating the building site. This article describes the three essential components of the ARMILLA5-model: the geometric model which describes the spatial and physical aspects of the building site, the semantic model which implements passive building components as objects and active building components as applets or applications, and the planning model, which organizes the work steps of the individual engineers and their cooperation. The model is described using different software prototypes written in Objective C, CAD systems and HTML/JAVA.

summary	Thinking of using computers in architecture, we have probably already learnt that there is much more than just one general way of doing so. At the same time, the general description of the field - i.e. the 'title' Computer Aided Architectural Design' has become a rhetorical figure - actually it covers much more activities than those just aiding design. To some extent computers change architecture introducing new values into it. This does not mean that they change architecture at all, but these new values begin to exist pararelly to the already present and accepted ones. In such sense architecture is changed - one of the possible branches of development is the one related to computers (no matter how complex this branch itself is).

title	COCSY II: CAD/CAM Integration for On-Site Robotics
source	Journal of Computing in Civil Engineering -- January 1997 -- Volume 11, Issue 1, pp. 17-25
summary	This paper discusses the need for automatic data extraction, processing, and transfer [computer-aided design and computer-aided manufacturing (CAD/CAM) interfacing] between the design and constructionphases as a key element in computer-integrated construction (CIC). The CAD/CAM interface eliminates the need for manual interfacing between these two computer-aided phases. The CAD/CAM interfaceimproves the process of the constructed facility realization by eliminating the manual data processing and thereby reducing many sources of errors. It also makes the process more cost-effective because it reduceslabor inputs, especially those presently invested in robot programming. A model for automatic data extraction, processing, and transfer is proposed for the tile-setting paradigm. The model generates constructionmanagement data as well as data needed for automatic on-site construction (robotics). The model is implemented in the AutoCAD and AutoLISP environments. The model and the implementation system weretested in the laboratories with a scaled robot adapted to perform interior finishing tasks.

source	Maher, M. L., Gero, J. S. and Sudweeks, F. (eds), Preprints Formal Aspects of Collaborative Computer-Aided Design, Key Centre of Design Computing, University of Sydney, Sydney, pp. 387-403
summary	In a multidisciplinary design environment, such as the AEC domain, the various designers will have their own concepts and representations of the design object making communication in such an environment a complex task. This paper argues for a multiple view approach based upon an assumption that different concepts of an object are based on different functional contexts. Thus an understanding of concepts such as function, purpose and intent is critical since the representation of the functional properties of design objects is the underlying basis for the formation of different concepts and coordination of these concepts. The paper points to the modelling of multidisciplinary design teams as cooperative intelligent agents in a distributed decisionmaking system where the explicit representation of function and purpose are essential, in a CAD environment, for the necessary communication of intent and effects.

title	Virtual reality interfaces for feature-based computer-aided design systems
source	Computer-Aided Design, Vol. 29 (8) (1997) pp. 565-574
summary	A computer-aided design (CAD) system with a virtual reality (VR) interface simplifies the design of complex mechanical parts. To add a design feature (e.g., a hole,slot, or protrusion), the designer can navigate in the part to the appropriate face of the part where he/she wishes to attach the feature, and sketch directly on that face.Besides convenience, this method of feature specification implicitly enforces feature accessibility constraints, and also provides hints to the process-planner regardingthe order in which the features may be manufactured. We detail the design of a VR-based prototype CAD system. The system maintains the knowledge of part cavitiesand their adjacencies, and a triangulated boundary-representation of an approximating polyhedron. We present incremental provably correct algorithms for updatingthis representation as the user edits the part. We also show how this representation supports real-time displays, navigation, and collision detection. The user-interfaceof the CAD system relies on these capabilities to provide the above-mentioned advantages.

title	Generic representations : an approach for modelling procedural and declarative knowledge of building types in architectural design
source	Eindhoven University of Technology
summary	The building type is a knowledge structure that is recognised as an important element in the architectural design process. For an architect, the type provides information about norms, layout, appearance, etc. of the kind of building that is being designed. Questions that seem unresolved about (computational) approaches to building types are the relationship between the many kinds of instances that are generally recognised as belonging to a particular building type, the way a type can deal with varying briefs (or with mixed use), and how a type can accommodate different sites. Approaches that aim to model building types as data structures of interrelated variables (so-called ‘prototypes’) face problems clarifying these questions. The research work at hand proposes to investigate the role of knowledge associated with building types in the design process.Knowledge of the building type must be represented during the design process. Therefore, it is necessary to find a representation which supports design decisions, supports the changes and transformations of the design during the design process, encompasses knowledge of the design task, and which relates to the way architects design. It is proposed in the research work that graphic representations can be used as a medium to encode knowledge of the building type. This is possible if they consistently encode the things they represent; if their knowledge content can be derived, and if they are versatile enough to support a design process of a building belonging to a type.A graphic representation consists of graphic entities such as vertices, lines, planes, shapes, symbols, etc. Establishing a graphic representation implies making design decisions with respect to these entities. Therefore it is necessary to identify the elements of the graphic representation that play a role in decision making. An approach based on the concept of ‘graphic units’ is developed. A graphic unit is a particular set of graphic entities that has some constant meaning. Examples are: zone, circulation scheme, axial system, and contour. Each graphic unit implies a particular kind of design decision (e.g. functional areas, system of circulation, spatial organisation, and layout of the building). By differentiating between appearance and meaning, it is possible to define the graphic unit relatively shape-independent.If a number of graphic representations have the same graphic units, they deal with the same kind of design decisions. Graphic representations that have such a specifically defined knowledge content are called ‘generic representations.’ An analysis of over 220 graphic representations in the literature on architecture results in 24 graphic units and 50 generic representations. For each generic representation the design decisions are identified. These decisions are informed by the nature of the design task at hand. If the design task is a building belonging to a building type, then knowledge of the building type is required. In a single generic representation knowledge of norms, rules, and principles associated with the building type are used. Therefore, a single generic representation encodes declarative knowledge of the building type. A sequence of generic representations encodes a series of design decisions which are informed by the design task. If the design task is a building type, then procedural knowledge of the building type is used.By means of the graphic unit and generic representation, it is possible to identify a number of relations that determine sequences of generic representations. These relations are: additional graphic units, themes of generic representations, and successive graphic units. Additional graphic units defines subsequent generic representations by adding a new graphic unit. Themes of generic representations defines groups of generic representations that deal with the same kind of design decisions. Successive graphic units defines preconditions for subsequent or previous generic representations. On the basis of themes it is possible to define six general sequences of generic representations. On the basis of additional and successive graphic units it is possible to define sequences of generic representations in themes. On the basis of these sequences, one particular sequence of 23 generic representations is defined.The particular sequence of generic representations structures the decision process of a building type. In order to test this assertion, the particular sequence is applied to the office building type. For each generic representation, it is possible to establish a graphic representation that follows the definition of the graphic units and to apply the required statements from the office building knowledge base. The application results in a sequence of graphic representations that particularises an office building design.Implementation of seven generic representations in a computer aided design system demonstrates the use of generic representations for design support. The set is large enough to provide additional weight to the conclusion that generic representations map declarative and procedural knowledge of the building type.

title	Towards Comprehensive Space: A context for the programming/design of cybrids
doi	https://doi.org/10.52842/conf.acadia.2003.161
source	Connecting >> Crossroads of Digital Discourse [Proceedings of the 2003 Annual Conference of the Association for Computer Aided Design In Architecture / ISBN 1-880250-12-8] Indianapolis (Indiana) 24-27 October 2003, pp. 161-171
summary	Cybrids have been presented as mixed realities: spatial, architectural compositions comprised of physical and cyberspaces (Anders 1997). In order to create a rigorous approach to the design of architectural cybrids, this paper offers a model for programming their spaces. Other than accepting cyberspaces as part of architecture’s domain, this approach is not radical. Indeed, many parts of program development resemble those of conventional practice. However, the proposition that cyberspaces should be integrated with material structures requires that their relationship be developed from the outset of a project. Hence, this paper provides a method for their integration from the project’s earliest stages, the establishment of its program. This study for an actual project, the Planetary Collegium, describes a distributed campus comprising buildings and cyberspaces in various locales across the globe. The programming for these cybrids merges them within a comprehensive space consisting not only of the physical and cyberspaces, but also in the cognitive spaces of its designers and users.

summary	The relationship between the media and architectural design can be an important factor and can influence the design outcome. However, the nature, direction and magnitude of this relationship are unknown. Consequently, there have been many speculative claims about this relationship and almost none of them are supported with empirical research studies. In order to investigate these claims and to provide a testable framework for their potential contributions to architectural education, this study aims to explore the effects of media on architectural design. During 1995-1997, a total of 90 students enrolling in First Year Design Studio and Introduction to Computing classes at Georgia Tech participated in the study. A set of quantitative measures was developed to assess the differences between the two media and the effects on the architectural design. The results suggested that media influenced certain aspects of students’ designs. It is concluded that there is a strong relationship between the media and architectural design. The type of media not only changes some quantifiable design parameters but also affects the quality of design.
