summary	In 1990, due to the traditional architecture design and construction method difficult to build the complicated and non-geometry free-form Fish Structure in Barcelona, architect Frank Gehry started learn from the field of aerospace to utilize CAD/CAM technology in design and manufacture process. He created the free-form fish model in CAD system and exported the digital CAD model data to CAM machine (RP and CNC) to fabricate the design components, and finally assembled on the site. Gehry pioneered in the new digital design process in using CAD/CAM technology or so-called digital fabrication. It becomes an important issue recently as the CAD/CAM technology progressively act as the new digital design media in architectural design and construction process (Ryder et al., 2002; Kolarevic, 2003). Furthermore, in the field of architecture professional, some commercial computer systems had been developed on purpose of standardizes the digital design process in using CAD/CAM fabrication such as Gehry Technologies formed by Gehry Partners; SmartGeometry Group in Europe and Objectile proposed by Bernard Cache. Researchers in the research field like Mark Burry, Larry Sass, Branko Kolarevic, Schodek and others are enthusiastic about the exploration of the role of CAD/CAM fabrication as new design media in design process (Burry, 2002; Schodek et al., 2005; Lee, 2005).

title	A strategy for complex-curved building design:Design structure with Bi-lateral contouring as integrally connected ribs
source	SIGraDi 2006 - [Proceedings of the 10th Iberoamerican Congress of Digital Graphics] Santiago de Chile - Chile 21-23 November 2006, pp. 465-469
summary	Shapes in designs created by architects such as Gehry Partners (Shelden, 2002), Foster and Partners, and Kohn Peterson and Fox rely on computational processes for rationalizing complex geometry for building construction. Rationalization is the reduction of a complete geometric shape into discrete components. Unfortunately, for many architects the rationalization is limited reducing solid models to surfaces or data on spread sheets for contractors to follow. Rationalized models produced by the firms listed above do not offer strategies for construction or digital fabrication. For the physical production of CAD description an alternative to the rationalized description is needed. This paper examines the coupling of digital rationalization and digital fabrication with physical mockups (Rich, 1989). Our aim is to explore complex relationships found in early and mid stage design phases when digital fabrication is used to produce design outcomes. Results of our investigation will aid architects and engineers in addressing the complications found in the translation of design models embedded with precision to constructible geometries. We present an algorithmically based approach to design rationalization that supports physical production as well as surface production of desktop models. Our approach is an alternative to conventional rapid prototyping that builds objects by assembly of laterally sliced contours from a solid model. We explored an improved product description for rapid manufacture as bilateral contouring for structure and panelling for strength (Kolarevic, 2003). Infrastructure typically found within aerospace, automotive, and shipbuilding industries, bilateral contouring is an organized matrix of horizontal and vertical interlocking ribs evenly distributed along a surface. These structures are monocoque and semi-monocoque assemblies composed of structural ribs and skinning attached by rivets and adhesives. Alternative, bi-lateral contouring discussed is an interlocking matrix of plywood strips having integral joinery for assembly. Unlike traditional methods of building representations through malleable materials for creating tangible objects (Friedman, 2002), this approach constructs with the implication for building life-size solutions. Three algorithms are presented as examples of rationalized design production with physical results. The first algorithm [Figure 1] deconstructs an initial 2D curved form into ribbed slices to be assembled through integral connections constructed as part of the rib solution. The second algorithm [Figure 2] deconstructs curved forms of greater complexity. The algorithm walks along the surface extracting surface information along horizontal and vertical axes saving surface information resulting in a ribbed structure of slight double curvature. The final algorithm [Figure 3] is expressed as plug-in software for Rhino that deconstructs a design to components for assembly as rib structures. The plug-in also translates geometries to a flatten position for 2D fabrication. The software demonstrates the full scope of the research exploration. Studies published by Dodgson argued that innovation technology (IvT) (Dodgson, Gann, Salter, 2004) helped in solving projects like the Guggenheim in Bilbao, the leaning Tower of Pisa in Italy, and the Millennium Bridge in London. Similarly, the method discussed in this paper will aid in solving physical production problems with complex building forms. References Bentley, P.J. (Ed.). Evolutionary Design by Computers.

summary	In the past, architects drew what they could build, and built what they could draw, as observed by Bill Mitchell. This reciprocity between the means of representation and production has not disappeared entirely in the digital age. Knowing the production capabilities and availability of particular digitally-driven fabrication equipment enables architects to design specifically for the capabilities of those machines. The consequence is that architects are becoming much more directly involved in the fabrication processes, as they create the information that is translated by fabricators directly into the control data that drives the digital fabrication equipment.

title	ARCHITECTURE IN THE DIGITAL AGE: DESIGN AND MANUFACTURING
source	Spon Press
summary	Architecture in the Digital Age addresses contemporary architectural practice in which digital technologies are radically changing how the buildings are conceived, designed and produced. It discusses the digitally-driven changes, their origins, and their effects by grounding them in actual practices already taking place, while simultaneously speculating about their wider implications for the future. The book offers a diverse set of ideas as to what is relevant today and what will be relevant tomorrow for emerging architectural practices of the digital age. The contents of the book brings together some of the leading international practitioners with the aim of providing informed views of what is seen as a critical juncture in architecture's evolving relationship to its wider cultural and technological context.

summary	Information and communication technologies (ICT) have brought about a revolution in architecture and urban planning; they are transforming learning and practice and presenting new challenges in our understanding of space, place and society. An entirely new world of architectural expression and experiment is opening up to us. At Faculty of Architecture in Zagreb a new optional course, Virtuality in Housing Architecture, has been proposed and is being taught for the first time. Subjects cover a wide area of use of ICT in housing architecture: research into the role of the computer in architecture as a creative discipline; encouragement of new challenges to the concept of the role of digital media in housing architecture through research of digital concepts such as computerization, information, electronic media, virtuality and cyberspace; themes related to development of intelligent environment and spaces, interactive buildings, virtual reality and cyberspace as directions of development. In our work we try to implement the method of e-learning, teamwork, communication and design through the Internet. Through experimental projects and research of new housing concepts, students create a basis for discussions on theoretical and practical solutions for the housing of the future, create new ways of presentation and open new fields of research. We shall here present the experience from our work.

summary	In the 21st century, as free-form design grows in popularity, grid shells are becoming a universal structural solution, enabling the conflation of structure and skin (façade) into one single element (Kolarevic 2003). This paper presents some of the results of a comprehensive research project focused on the automated design and optimization of grid structures over some predefined free form shape, with the goal of generating a stable and statically efficient structure. It shows that by combining design and FEM software in an iterative, Genetic Algorithms-based optimization process, stress and deformation in grid shell structures can be significantly reduced, material can be saved and stability enhanced.

summary	The use of digital fabrication in the discourse and education of architectural students has become a common skill in many schools of architecture. There is a growing demand for computer-aided design (CAD) skills, computer-aided manufacturing (CAM) logic, programming and fabrication knowledge in student education. The relevance of fabrication tools for architecture and design education goes beyond mere competence and can pursue innovation in what Branko Koleravic (2003) observed, “The digital age has radically reconfigured the relationship between conception and production, creating a direct digital link between what can be conceived and what can be built through “file-to-factory” processes of computer numerically controlled (CNC) fabrication”. However, there has been very little written about what students are actually learning through digital fabrication courses and the relevance of the skills required for innovation in the field of digital fabrication.

title	A maintenance contract for the architect's degree - Concept, materialisation and post-occupancy
source	Ebbe Harder (ed.), Writings in Architectural Education, Transactions on architectural education No 15, EAAE/AEEA, pp.134-147
summary	Today, architecture is confronted with changing concepts of time, space and place. These changes are largely induced by the advent of the information society and in turn induce the need for entirely new ways of conceiving architectural education. It is obvious, however, that architectural education does not hold absolute sway over the need for renewal, as other domains and disciplines too are confronted with the inevitable learning society: a society in which individuals, groups and companies are learning on a permanent basis. What architectural education does hold absolute sway over – or at least should be granted a patent for – is the unique way in which it used to prepare (and still prepares) its students for practice in the design studio. Therefore, instead of throwing out the design studio with the bathwater, we consider it as an outstanding lead for pursuing the learning society within the context of architecture. Furthermore, we see ICT not only as a cause of, but at the same time as an ally in this pursuit, as it allows reinforcing the studio as “espace transitoire”. To this end, we propose to literally connect the studio with the world of practice through an on-line platform constructed of concrete cases.

summary	This paper proposes a computational model of design that attempts to capture within a social context two important aspects of style: ‘content’ and ‘manner’. We present a characterisation of style for the artefact based on a framework that consists of information theoretic measures. We discuss the benefits the study of social networks offers a computational analysis of both aspects of style. It is our aim to bring style as ‘content’ and style as ‘manner’ together using this approach.

title	Towards a dynamic evacuation system: developing methodologies to simulate the evacuation capabilities of subway stations in response to a terrorist attack with CBRNE weapons
doi	https://doi.org/10.52842/conf.ecaade.2014.1.109
source	Thompson, Emine Mine (ed.), Fusion - Proceedings of the 32nd eCAADe Conference - Volume 1, Department of Architecture and Built Environment, Faculty of Engineering and Environment, Newcastle upon Tyne, England, UK, 10-12 September 2014, pp. 109-118
summary	Events in recent times have highlighted the vulnerability of underground public transportation to possible terrorist attacks. A key question therefore is how an evacuation can be accomplished from underground stations safely. The strategy “go up and take the nearest exit to the surface” might not be the best response. Evidence from the Daegu subway station fire in 2003, investigated by Tsujimoto (2003) and Jeon and Hong (2009) establish that smoke or toxic airborne substances from a terrorist attack tend to use the same direct routes used by the fleeing passengers and as result significant injuries or fatalities can occur. This study proposes the concept of a dynamic evacuation system which would guide subway users along safe routes. To test how this system may operate, the study discussed combines measurements from tracer gas experiments with climate measurements to establish how toxic agents spread in subway stations under certain conditions and combines these results with those from pedestrian simulations applied to calculate evacuation times for possible escape routes. By integrating the resulting dataset from these methods, an evidence base of how a dynamic evacuation system may work can start to form.

title	HOUSING TYPES AND CLASSIFICATION SYSTEMS IN CASE-BASED DESIGN
source	Proceedings of the 37th ANZAScA Conference (S Mayman ed), November 1-4, University of Sydney, Australia, pp. 383-395.
summary	Expert designers typically refer to and re-use past solutions for recurring design problems. Case-based design (CBD) attempts to transfer this natural design reasoning process to computer-aided design using artificial intelligence (AI) methods and databases. The housing design domain is particularly suited for applying the CBD approach because the traditional method of home design already makes extensive use of precedents and solutions are highly standardized in that industry, at least in the U.S. This paper introduces classificatory types of housing precedents that provide a basis for a structured knowledge representation that supports case retrieval. The classificatory types gives to a research prototype an efficient classification and indexing mechanism that combines form- and component-based features and remains flexible (i.e. can be modified and customized by users), and a retrieval mechanism that uses the indexing mechanism.

summary	Architecture is presently engaged in an impatient search for solutions to critical questions about the nature and the identity of the discipline. Meanwhile, evolving digital technology continues to serve as a key agent for prevailing innovations and new ideas in architecture. Still, this feels familiar, as technology has always been a catalyst for new ideas in architecture. A positive digital future in architecture requires a clearer definition of principles and skills necessary to maintain a rigor in emerging digital projects/projections. At the same time, recognition about the significance of the already existing digital scholarship in architecture must be connected with emerging lines of inquiry evolving within the discipline. Healthy disciplines remain tolerant of a state of flux by constantly questioning the inclusion\|exclusion, import\|export, and collaboration\|isolation to\|from new ideas, new techniques, new disciplines, and new technology. At the perimeter of this nebulous exchange, an innovative new digital discourse is emerging that offers some unexpected new conduits to an attentive discipline of architecture. Topic nodes have evolved which augment this discourse with overlapping issues, as well as a particular set of important distinctions from one another: Digital Pedagogy, Digital Tools, Digital Production/ Fabrication, Digital Visualization, Digital Projects, Digital Design, Digital Representation, Digital Thinking, and Digital Practice.

title	REASONS TO STOP TEACHING CAAD
source	Mao-Lin Chiu (ed), Digital design education, Garden City Publishing, Taipei 2003, ISBN 9867705203
summary	Computers are a problem. They are expensive, even if the prices have dropped dramatically and promise to continue dropping. They do not look after themselves but demand considerable attention – we have to hire computer specialists to ensure they talk to each other, staff are required to make sure software is installed and to fix things when it no longer works. Learning to use them is tedious; skills have to be developed to master several idiosyncratic software systems. The hardware and software regularly malfunction. It is faster to draw a line by hand than with software. Students already have enough trouble learning how to stop a window leaking or ensure a fire escape route will protect people in time of trouble, why make them learn all these other things. We should stop teaching CAAD. Although technological and economic issues are very real and not to be dismissed lightly, the real problems of teaching CAAD are not these. The real issues we need to address is how we teach and, behind that, why we teach. This paper explores the what and why.

summary	Design is the activity of making explicit proposals for a change from some existing state to some future state which more closely approximates to mankind's concept of the ideal. As such it embraces a wide spectrum of human endeavour; the outcomes of design activity are part and parcel of our everyday life and are determinants, for better or worse, of our man-made future. In common with all complex human functions the activity of design is ill-understood: it involves the most rational and systematic process of human thought and also the most intuitive and conjectural leaps within the human mind.

title	DESIGN AGENTS IN 3D VIRTUALWORLDS
source	IJCAI03 Workshop on Cognitive Modeling of Agents and Multi-Agent Interaction, R Sun (ed), IJCAI, Acapulco, pp 92-100.
summary	Design agents are rational agents that monitor and modify elements of a designed environment. Special characteristics of design agents include the ability to reason about patterns and concepts, and the ability to act autonomously in modifying or changing the design to achieve their own goals. 3D Virtual Worlds are multi-user distributed systems that provide a designed environment and a closed world environment for studying design agents in a multiagent system. We present a model for a design agent reasoning process and a model for constructing a memory of the agent’s knowledge and interaction with a virtual world. The reasoning process includes sensation, perception, conception, hypothesizing, and planning a sequence of actions. Each agent has a constructed memory: a dynamic and changing view of the designed world that is determined by the agents sense data and reasoning. The agents construct and maintain a representation of the relevant objects in the world using a Function- Behavior-Structure formalism in order to reason about the intended and actual functions of the designed objects in the world. We have implemented this agent model by extending the Active Worlds platform so that each object in the 3D world can have agency. We illustrate the model with a door agent and a multi-agent room that reason about the use of the 3D world.

title	Mass-Customization in the Design of 4,000 Bus Stops
source	Computer Aided Architectural Design Futures 2011 [Proceedings of the 14th International Conference on Computer Aided Architectural Design Futures / ISBN 9782874561429] Liege (Belgium) 4-8 July 2011, pp. 265-278.
summary	In Hawaii, ‚"TheBus‚" has been a main transportation system since 1971. Considering the high cost of living in Hawaii and the absence of a rail system, the use of ‚"TheBus‚" has been an instrumental vein of the city life in Honolulu with rhythmical pauses at about 4,000 bus stops in Honolulu. However, existing undifferentiated bus stops are developed from a cost effective mass production system so that they have been problematic for satisfying specific needs from various site conditions. In this research, an integrated computational method of mass-customization for designing 4,000 bus stops is introduced. According to various site conditions, the design of each bus stop is customized. Unlike the mass‚Äêproduced bus stops commonly seen in cities today, the proposed computational method in this paper produces bus stop design outcomes that fit into the physical characteristics of the location in which they are installed. Mass-customization allows for the creation and production of unique or similar buildings and building components, differentiated through digitally‚Äêcontrolled variation (Kolarevic, 2003). The employment of a computational mass‚Äêcustomization in architectural design extends the boundary of design solutions to the satisfaction of multi-objective requirements and unlimited freedom to search alternative solutions (Duarte, 2001; Caldas, 2006). The computational method developed in this paper consists of 1) definition of a prototype, 2) parametric variation, 3) manual deformation, and 4) simulation based deformation. The definition of a prototype is the development of a basic design to be transformed for satisfying various conditions given from a site. In this paper, the bus stop prototype is developed from the analysis of more than 300 bus stops and the categorization of the existing bus stops according to their physical conditions, contextual conditions, climatic conditions, and existing amenities. Based upon the outcome of the analysis, the design variables of a bus stop prototype are defined. Those design variables then guide the basic physical parameters for changing the physical configuration of the prototype according to a given site. From this, many possible design outcomes are generated as instances for further developments. The process of manual deformation is where the designer employs its intuition to develop the selected parametric variation. The designer is compelled to think about the possible implication derived from formal variation. This optional process allows every design decision to have a creative solution from an individual designer with an incidental quality in aesthetics, but substantiated functional quality. Finally the deformation of the selection is guided and controlled by the influence of sun direction/ exposure to the selection. The simulation based deformation starts with the movement of the sun as the trigger for generating the variations of the bus stop prototype. The implementation of the computational method was made within the combination of MEL (Maya Enbedded Language), autodesk MAYA and Ecotect environment.
