summary	The creditability of using CAAD depends on the rigour of its methodology, the logic of its deduction and most importantly the feasibility of its results for practical use. This paper examines two lighting simulation software as the basis for providing a wider critic on the research of CAAD in the practice of architecture. The paper argues that the ‘contextual’ and appropriate use of a simple tool or method should be the thesis of CAAD research. Using an example, the paper then logically work out an example of how that could be done, and the basis of its contextual logic. The example illustrated here concludes the validity of the software and its implication for legal use. Furthermore, the paper provides a critic of CAAD for regulatory and legal acceptance. The experience in Hong Kong is illustrated.

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.

title	A Daylight Design and Regulatory Method for High-Density Cities Using Computational Lighting Simulations
source	Digital Design - Research and Practice [Proceedings of the 10th International Conference on Computer Aided Architectural Design Futures / ISBN 1-4020-1210-1] Tainan (Taiwan) 13–15 October 2003, pp. 339-350
summary	Hong Kong is the most densely populated city in the world. Design of buildings in urban Hong Kong is regulated by the Building (Planning) regulations of the Government. This piece of law is over 40 years old and has been proven to be inadequate. This paper introduces a new simplified method, the Unobstructed Vision Area Method (UVA), for daylight design in high-density cities. The method was developed based on empirical and theoretical formulation as well as extensive validation and studies using computational simulations. The paper highlights the steps necessary to apply computational methods for law making, the difficulties and possibilities in the process, as well as the practical and implementation of adopting computational results and techniques in everyday practical life of the architect and the controlling agency. The Government of Hong Kong has recently adopted the UVA method.

title	Towards Comprehensive Space: A context for the programming/design of cybrids

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.

title	A Critical Evaluation of Early Stages Software in its Capacity of Coping with Contextual Issues
source	LOCAL VALUES in a NETWORKED DESIGN WORLD - ADDED VALUE OF COMPUTER AIDED ARCHITECTURAL DESIGN, Stellingwerff, Martijn and Verbeke, Johan (Eds.), (2004) DUP Science - Delft University Press, ISBN 90-407-2507-1.
summary	In this paper we analyse critically early design stages software in its capacity of coping with contextual data at large (i.e. representing cultural, aesthetical context, etc.). We identified 5 categories of early stages software: geometry based graphic editors, evaluation architectural software, generative and shape-grammar based systems, evolutionary systems and other systems. Calling the object under creation during of the early stages a CAD conceptual model, we will investigate to what extend this software allows the architect to experience and represent the context in which a design is situated. Especially we will focus on its capacity to allow interaction, playful interaction on our way to the design. Designers, and particularly architects, interact with the local context similarly to interacting in a game: the context influences the users’ decisions, surprises them and causes permanent changes to their ways of thinking. On the other hand, architects permanently shape and reshape the context, and reduce the context to a protean point of reference. Such behaviour characterises creative thinking that is crucial for the early stage of design. The investigation led us to the conclusions that the effective interactivity with the context needs simple rules, a plain interface and data reduced as simple as possible, especially when interaction with the context is performed during the early stages of a design process. The findings can be used in organising computer environments for early-stage design.

title	Architectural Composition in Digital Space
doi	https://doi.org/10.52842/conf.ecaade.2003.587
source	Digital Design [21th eCAADe Conference Proceedings / ISBN 0-9541183-1-6] Graz (Austria) 17-20 September 2003, pp. 587-590
summary	In this paper the possibilities of using the computers at course of architectural compositions are considered. As the start point of the new teaching method of architectural composition we used the course of tradition architectural composition, elaborated at our Faculty. The course of Digital Architectural Composition was finished in 2002. The main goal of using the new digital media for modelling architectural forms was checking the new possibilities of form creation. Traditionally, searching of forms at the conceptual design stage is performed by using sketches, drawings and physical models. Our new method showed that is possible to do the same thing using the computerbased 3D modelling, experiencing no physical limitations of the 'real' substance. At the same time, at the early design stages, when formal value is sought, computer modelling can be done almost intuitively. In ours work we try to find a creative way of using computer - transforming the tool into medium. The attention was paid on exploring the possibilities characteristic for computers and not available with traditional methods of modelling. Architect’s tradition tools are effectively replaced by a computer, which create a new way of doing things.

title	A Preliminary Model of Community-based Integrated Information System for Urban Spatial Development
source	Proceeding of the 3rd China Urban Housing Conference, July 3-5 2003, Center for Housing Innovations, Chinese University of Hong Kong, ISBN 962-8272-26-8, pp. 417-424
summary	This paper describes a research on building Integrated Information System for Urban Spatial Development. The objective of the research phase discussed in this paper is to define a prototype of information system that basically facilitates information communication among involved participants in an urban spatial development planning. The system is designed by putting stress on local community. Their spatial perception and the availability of GIS technology in local context become constraints in building the system. Internet becomes the main alternative for information dissemination for this phase. This is also supported by the use of web-based GIS as framework of information system. Through few socialization sessions, the proposed model has indicated a prospected alternative to be seamless communication media among participants. To support an easy-access for local people in using this information system a mechanism of information access has been proposed in the form of local information center.

title	Computing And Manipulation In Design - A Pedagogical Experience Using Symmetry
source	SIGraDi 2008 - [Proceedings of the 12th Iberoamerican Congress of Digital Graphics] La Habana - Cuba 1-5 December 2008
summary	The concept of symmetry has been usually restricted to bilateral symmetry, though in an extended sense it refers to any isometric transformation that maintains a certain shape invariant. Groups of operations such as translation, rotation, reflection and combinations of these originate patterns classified by modern mathematics as point groups, friezes and wallpapers (March and Steadman, 1974). This extended notion represents a tool for the recognition and reproduction of patterns, a primal aspect of the perception, comprehension and description of everything that we see. Another aspect of this process is the perception of shapes, primary and emergent. Primary shapes are the ones explicitly represented and emergent shapes are the ones implicit in the others (Gero and Yan, 1994). Some groups of shapes known as Semantic Shapes are especially meaningful in architecture, expressing visual features so as symmetry, rhythm, movement and balance. The extended understanding of the concept of symmetry might improve the development of cognitive abilities concerning the creation, recognition and meaning of forms and shapes, aspects of visual reasoning involved in the design process. This paper discusses the development of a pedagogical experience concerned with the application of the concept of symmetry in the creative generation of forms using computational tools and manipulation. The experience has been carried out since 1995 with 3rd year architectural design students. For the exploration of compositions based on symmetry operations with computational support we followed a method developed by Celani (2003) comprising the automatic generation and update of symmetry patterns using AutoCAD. The exercises with computational support were combined with other different exercises in each semester. The first approach combined the creation of two-dimensional patterns to their application and to their modeling into three-dimensions. The second approach combined the work with computational support with work with physical models and mirrors and the analysis of the created patterns. And the third approach combined the computational tasks with work with two-dimensional physical shapes and mirrors. The student’s work was analyzed under aspects such as Discretion/ Continuity –the creation of isolated groups of shapes or continuous overlapped patterns; Generation of Meta-Shapes –the emergence of new shapes from the geometrical relation between the generative shape and the structure of the symmetrical arrangement; Modes of Representation –the visual aspects of the generative shape such as color and shading; Visual Reasoning –the derivation of 3D compositions from 2D patterns by their progressive analysis and recognition; Conscious Interaction –the simultaneous creation and analysis of symmetry compositions, whether with computational support or with physical shapes and mirrors. The combined work with computational support and with physical models and mirrors enhanced the students understanding on the extended concept of symmetry. The conscious creation and analysis of the patterns also stimulated the student’s understanding over the different semantic possibilities involved in the exploration of forms and shapes in two or three dimensions. The method allowed the development of both syntactic and semantic aspects of visual reasoning, enhancing the students’ visual repertoire. This constitutes an important strategy in the building of the cognitive abilities used in the architectural design process.

title	APPROPRIATE LEVELS OF ACCESS: AN EMPIRICAL STUDY ON THE AVAILABILITY OF COMPUTERS IN STUDIO
doi	https://doi.org/10.52842/conf.acadia.2003.119
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. 119-127
summary	One of the most significant technological challenges facing architecture schools today is how to provide an appropriate level of access to computing resources. As the computer has become a significant tool in the study and practice of architecture, students need to have access to that tool in order to further their studies. But in facing this question of access, what is “appropriate”? Is there such a thing as too much access? Is 1:1 access—a computer for every student—the minimum level of access that schools and students should accept? Or is there a point beyond which more resources just means more waste; computers sitting idle and unused, or students using the computer for unproductive ends? These questions were the subject of an experimental series of studios in the spring of 2002, wherein three studios were given varying numbers of computers for a term. The use of these computers was then tracked, and compared with previous terms. In tandem, the quality of work produced by these three studios was compared. While additional experiments are most likely needed to draw firm conclusions, the results of this experiment seem to support defining “an appropriate level of access” at less than 1:1.

title	The pattern of Internet use for information management by architectural practices in the UK
source	Cardiff University, Welsh School of Architecture Cardiff, UK
summary	In recent history, architects have experienced problems related to the use and management of new innovations. The Internet presents one such challenge. It offers considerable expansion in types of communication and sources of business information and connects people and businesses around the globe. As is argued in this research, these services could play a positive role in architectural practice. This research examines the use of the Internet by architectural practices in UK in order to reveal how aware they are of the opportunities it presents, the extent to which they are taking advantage of them, and the problems they are experiencing. A field study was conducted of two types of practices: RIBA private practices and local authority practices. A number of research tools were used to inspect how these practices are using the Internet to manage various types of information that used and produced in the practice, namely: the acquisition of web information, the exchange of the practice’s information through the web and the presentation of the practice’s information on the web. Explanations for the results were sought by correlating variables from the questionnaire study, using simple statistical tests. The field study shows that many Internet services are unpopular among architects, and that practices have problems in adopting and using the technology. The pace at which the Internet is being absorbed and accepted by practices is slow. The study suggests that possible causes are: the little knowledge of users’ about IT, the poor resources of the practice, and old or imperfect Internet installations and the absence of the Internet support to the architect’s activities. The research argues that there are a number of links between these negative factors which make the practice unable to utilize the Internet and to manage the practice’s information through the Internet. To break these links, the research suggests that practices should adopt a specific management strategy to promote more utilization of Internet services in the office and to manage information. Practices need to make certain changes to the way they manage the Internet and work with it, if they plan to integrate the Internet more successfully into their practice. The research discusses techniques for improving practice management which would help practices to digest Internet technology and to use it more effectively in the practice.

title	Understanding Pre-Construction Simulation Activities to Adapt Visualization in 4D CAD Collaborative Tools
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. 477-492.
summary	Increasing productivity and efficiency is an important issue in the AEC field. This area is mainly characterized by fragmentation, heterogeneous teams with low lifetimes and many uncertainties. 4D CAD is one of the greatest innovations in recent years. It consists in linking a 3D model of the building with the works planning in order to simulate the construction evolution over time. 4D CAD can fill several needs from design to project management through constructivity analysis and tasks planning (Tommelein 2003). The literature shows that several applications have been proposed to improve the 4D CAD use (Chau et al. 2004; Lu et al. 2007; Seok & al. 2009). In addition, studies have shown the real impact of 4D CAD use in construction projects (Staub-French & Khanzode 2007; Dawood & Sika 2007). More recently, Mahalingam et al. (2010) showed that the collaborative use of 4D CAD is particularly useful during the pre-construction phase for comparing the constructability of working methods, for visually identifying conflicts and clashes (overlaps), and as visual tool for practitioners to discuss and to plan project progress. So the advantage of the 4D CAD collaborative use is demonstrated. Moreover, several studies have been conducted both in the scientific community and in the industrial world to improve it (Zhou et al. 2009; Kang et al. 2007). But an important need that remains in collaborative 4D CAD use in construction projects is about the adaptation of visualization to the users business needs. Indeed, construction projects have very specific characteristics (fragmentation, variable team, different roles from one project to another). Moreover, in the AEC field several visualization techniques can represent the same concept and actors choose one or another of these techniques according to their specific needs related to the task they have to perform. For example, the tasks planning may be represented by a Gantt chart or by a PERT network and the building elements can be depicted with a 3D model or a 2D plan. The classical view (3D + Gantt) proposed to all practitioners in the available 4D tools seems therefore not suiting the needs of all. So, our research is based on the hypothesis that adapting the visualization to individual business needs could significantly improve the collaboration. This work relies on previous ones and aim to develop a method 1) to choose the best suited views for performed tasks and 2) to compose adapted multiple views for each actor, that we call ‚Äúbusiness views‚Äù. We propose a 4 steps-method to compose business views. The first step identifies the users‚Äô business needs, defining the individual practices performed by each actor, identifying his business tasks and his information needs. The second step identifies the visualization needs related to the identified business needs. For this purpose, the user‚Äôs interactions and visualization tasks are described. This enables choosing the most appropriate visualization techniques for each need (step 3). At this step, it is important to describe the visualization techniques and to be able to compare them. Therefore, we proposed a business view metamodel. The final step (step 4) selects the adapted views, defines the coordination mechanisms and the interaction principles in order to compose coordinated visualizations. A final step consists in a validation work to ensure that the composed views really match to the described business needs. This paper presents the latest version of the method and especially presents our latest works about its first and second steps. These include making more generic the business tasks description in order to be applicable within most of construction projects and enabling to make correspondence with visualization tasks.

summary	While the introduction of digital media in the design studio often emphasizes virtual realms, the effect of new fabrication technology on the architect brings the architect back to the realm of master-builder rather than distancing the architect from reality. While purely digital projects have pushed the development of form, they have also placed an emphasis on form over material. However, with the intention to physically build a project, the connections between process, form, and material become intertwined. The inception of this project also served as a clear reminder that the tools we use affect the way we think. This project began as a simple idea: how a column becomes animated to form an arch over time. The digitization of this idea took literally minutes in Maya. It was exported and further modeled in AutoCAD, and then rendered and reanimated in 3D Studio-Viz. This was a very brief, two-week introductory project, in a class on drafting and wood light-frame construction. It served to make a greater connection between digital media, the design process, analog drawing, and the role of craft and material.

summary	The Generative Design System [GDS] presented in this paper was developed to assist designers in researching low-energy architecture solutions. The GDS has the capability to evolve architectural forms that are energy-efficient, while complying to design intentions expressed by the architect, and responding to conflicting objectives. To achieve this evolutionary development, the system integrates a search and optimization method [Genetic Algorithm], a building energy simulation software [DOE2.1E], and Pareto multicriteria optimization techniques. The GDS adaptively generates populations of alternative solutions, from an initial schematic layout and a set of rules and constraints designed by the architect to encode design intentions. The two conflicting objective functions considered in this paper are maximizing daylighting use, and minimizing energy consumption for conditioning the building. The GDS generated an uniformly sampled, continuous Pareto front, from which six points were visualized in terms of the proposed architectural solutions.

title	Automated Generation of Residential Roomlayout within a Constrained Covered Area
doi	https://doi.org/10.52842/conf.caadria.2003.085

summary	A significant quantum of all buildings constructed in modern times is designed for residential purpose. A tremendous amount of money is being spent every year for construction of residential buildings. Therefore, optimization of design becomes very important. In a country like India most people in urban area live in houses having constrained area. A significant part of residential units comes under mass housing either as high-rise building blocks or as plotted developments. In any of such schemes there are large number of housing units for a group of families of whom general characteristics are known but characteristics of individual families are not known at the time of designing. This situation is, however, suitable for scientific investigation and analysis based on statistical surveys. Broadly speaking, this paper suggests approach to deal with this situation of finding optimum layout of rooms of a housing unit for any target group of families when the covered area is so constrained that freedom of using different criteria like aesthetics, structural systems, materials and methods of construction in varieties of ways is drastically reduced. In such constrained area for housing units rooms are generally found rectangular within overall rectangular outline of each unit. Method shown here is valid under this restriction. It is also assumed that number of rooms will be restricted to such number that exhaustive search for design is practically possible within a reasonable time with present day capabilities of normally available PCs.

title	A Simulation Study on Public Building's Staircase Fault Tolerance
source	Digital Design - Research and Practice [Proceedings of the 10th International Conference on Computer Aided Architectural Design Futures / ISBN 1-4020-1210-1] Tainan (Taiwan) 13–15 October 2003, pp. 393-402
summary	This paper applies the concept of fault tolerance to staircase layout plan. Fire or smoke may cause some staircases in a building inaccessible. We argue that architects should assess the result from the possible fault of vertical routes. The capability of tolerating staircase faults depends on space usage, arrangement, and pedestrian attributes. In this study, a mathematical model is constructed. For analysing pedestrian's movement in interior space, we employ Monte Carol simulation and Agent-Based Modelling method in a CAAD environment. It helps us to visualise the dynamic process of agent's evacuation process, and to test the problem of possible staircase faults. Finally, a case study brings some important discoveries.

title	IMPROVING NEURAL NETWORK MODELS OF PHYSICAL SYSTEMS THROUGH DIMENSIONAL ANALYSIS
source	Journal of Applied Soft Computing 2(4): 283-296.
summary	The paper presents a technique for generating concise neural network models of physical systems. The neural network models are generated through a two-stage process. The first stage uses information embedded in the dimensions or units in which the data is represented. Dimensional analysis techniques are used initially to make this information explicit, and a limited search in the neural network architecture space is then conducted to determine dimensionless representations of variables/parameters that perform well for a given model complexity. The second stage uses information available in the numerical values of the data to search for high-level dimensionless variables/parameters, generated from simple combinations of dimensionless quantities generated in the first stage and which result in concise neural network models with improved performance characteristics. The search for these high-level dimensionless variables/parameters is conducted in an enhanced representation space using functional link networks with flat or near flat architectures. The use and effectiveness of the technique is demonstrated for three applications. The first is the design and analysis of reinforced concrete beams, which is representative of the class of problems associated with the design and analysis of composites. The second is the classical elastica problem, for predicting non-linear post-buckled behaviour of columns and the third, the analysis of a bent bar under a specified combination of loads.

title	AN INCLUSIVE ‘WORK-METHOD’ AND A SPECIFIC SEARCH FOR FULLY SUPPORTED SOLUTIONS THROUGH SUBJECTORIENTED DESIGN (INSTEAD OF OBJECT-ORIENTED)!

summary	This paper talks about the hardness of CAAD.And it talks about the necessity to develop ‘soft’ CAAD.A lot of architectural adventures are stopped in the beginning or the middle of the road. Because of decisions far away from the designers or the clients. These decisions break in against some aspects of the design. Small details often kill a whole design-process.Does architectural design only belong to architects and planners ?To a “Me, myself and I”-world ? For the last 10 years, we have gained a lot of experience of designing architectural landscapes in a specific way. We design in such a way that developing projects can change or evolve strongly within themselves without losing their typical spirit. Change because of external and non-predictable events, change because of unexpected or changing circumstances, change because of the participation of new intervening people….New housing projects in Apeldoorn and Dordrecht,Rehabilitation projects in Gennevilliers (Paris) and Hellersdorf (Berlin), …Schools and hospitals in Amsterdam, …Each time very local aspects are incorporated in the different design-spirits.The networks are similar because of specific design-methods.This paper wants to explain something about this process-spirit.

title	The Tangible Interface: Experiments as an Integral Part of a Research Strategy
source	International Journal of Architectural Computing vol. 1 - no. 2
summary	The Human-Computer interface is crucial to good design support tools. It has to be non-interruptive and non-distracting, yet allow the architect to interact with the computer software. The physical reality of the interface, such as the shape and manipulability of devices like the mouse, keyboard, joystick, or data-glove, has to be mapped on actions and commands in the software. Already the current user interfaces are felt to be inadequate for a good support of design, and the functionality of design tools is growing, requiring even more and new physical interface devices. In this paper, we present research on new tangible interfaces for architectural design support. In particular, we focus on the research methodological question how to investigate such devices.The research strategy is introduced and discussed, after which concrete implementations of this strategy are shown. Based on this work, we conclude that the combination of interface and the context of its use in terms of design method and user needs form crucial aspects for such research and cannot be considered separately.
