summary This contribution explores the continued evolvement of the instruments of design in relation to practice and education (and potentially: research) and attempts to characterize the effects brought about by recent media ‘shifts’. For this purpose a framework has been established to identify and ‘map’ relevant design media. The relationships between various ‘traditional’ media and computer based applications are scrutinized and characterized and the opportunities which they offer are compared. The underlying conceptual framework was recently put before a group of professionals in the in the course of an experimental workshop concerning the potentials of a virtual design media ‘museum’. In the following step an attempt is made to identify changing media roles, whereby the opportunities of the educational environment – as a ‘laboratory’ for emerging developments – is stressed. Some specific tendencies are identified, notably: the combined application of different sorts of design media; the surfacing of imaginative new working methods inspired by ‘classic’ media techniques and various new ways of escaping the serious limitations of traditional computer interfaces. These developments, making use of various types of computer platforms, may be expected to contribute to more structured – and imaginative – approaches to professional design as well as to architectural education and research.

title DISTANCE TEACHING OF MATHEMATICS FOR STUDENTS OF ARCHITECTURE: IS IT POSSIBLE?
source Proceedings of the Fourth International Conference of Mathematics & Design, Special Edition of the Journal of Mathematics & Design, Volume 4, No.1, pp. 105-109.
summary On the basis of our experience as teachers of Mathematics in the School of Architecture of the University of Buenos Aires and with the support of an expert designer of image and sound, we undertook the task of distance teaching the subject Mathematics II for students of Architecture. The academic guidance of Ms Spinadel, PhD, the university’s authorization and the support of a computer platform provided by Nueva Internet S.A. have enabled the completion of this project. We were encouraged to set up the distance teaching of the subject by the many advantages the system offers, namely, the chance for students to work at home with a computer-based platform containing all of the subject’s contents and to integrate and apply all the knowledge acquired in architectural contexts; and the chance for teachers to offer on-line guidance and tutorials. Distance teaching is not to be understood or configured as an accumulation of calculus procedures. Rather, it should be thought of as having the major aim of promoting the full development of the students’ imagination for the solution of architectural design problems. For that purpose, students must become familiar with the interface to be used as the virtual classroom, read the theoretical introduction to every one of the units, solve application problems (the students are provided with all the material, which they can visualize on line or print), and send their tutor all the queries they may have so that the process of teaching and learning is facilitated and enriched. The solution to exercises is presented in a didactic manner and students can resort to additional bibliography, image and formula galleries and a technical help forum provided by the software firm. A virtual classroom has been set up where students and teachers interact all the time. Students must also submit integrative assignments, which are corrected by the tutor and will form part of the subject’s final assessment, together with an in-person exam at the end of the semester. Excellent results have been obtained so far, being that this is the first time a subject of the Architecture course is taught this way. This paper is intended to share this experience and show how, in spite of the modality of the subject, the interaction achieved between students and teachers has proved to be very enriching.

title Towards a Multi Agent System for the Support of Collaborative Design

summary In this paper we are drafting the outline of a framework for a Multi Agent System (MAS) for the support of Collaborative Design in the architectural domain. The system we are proposing makes use of Machine Learning (ML) techniques to infer personalized knowledge from observing a users’ action in a generic working environment using standard tools such as CAD packages. We introduce and discuss possible strategies to combine Concept Modelling (CM)-based approaches using existing ontologies with statistical analysis of action sequences within a domain specific application. In a later step, Agent technologies will be used to gather additional related information from external resources such as examples of similar problems on the users hard disk, from corresponding work of team-members within an intranet or from advises of expert from different knowledge domains, themselves represented by agents. As users deny or reward resulting proposals offered by the agent(s) through an interface the system will be enhanced over time using methods like Reinforced Learning.

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 “business views”. We propose a 4 steps-method to compose business views. The first step identifies the users’ 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’s 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 Contemporary computer techniques offer many new opportunities to engage citizens into the planning process. There are new possibilities of interaction, introducing an observer into the “game”. The research project presented in the paper assumes the use of a visual 3D language which consists of a series of schematic types of buildings. They form a language which is easy to understand both by professionals and by laymen. Understanding is the very first step towards getting convinced by the ideas presented. The next step is interaction - the user’s action induces the response of the system. The solution proposed by the user meets an evaluation from the part of the system which evokes the user’s interest - in the case presented here the evaluation introduces the simulation of future state of the site. The problem posed is to find out the best way to convince people that some places are less or more suitable for settlement, depending on the media present there, distance from the urban areas and the environment protection. The attempt to create a tool which could be helpful in an educational process is described in the paper. The idea is to prepare a form of a master plan record which uses the visual 3D language and may be accessed via World Wide Web pages. The paper formulates the assessments for the software described above and examines the possibility to create an application. The trial to prepare a web based service using the flash and shockwave technology is presented.

summary Previous research (Bourdakis et al, 2012; Papasarantou et al, 2013) dealt with the problem of creating information visualisation systems capable of combining historical data of MUCIV's database and developing strategies that embed the non-spatial data in spatial models. The database was primarily designed as an experimental flexible spatio-temporal configuration of dynamic visual structures generating a variety of narrations through interaction.The attempt of producing a legible configuration driven by a number of criteria, led to the proposition of two different arrangements, namely the linear and radial array. The aim of this paper is to present the next step on the visualization after redefining both the way that thematic axes and data are visualized and arranged/scattered. Alternate configurations are investigated, based also on theoretical analysis on the conceptualization and perception of information visualization systems (Card et al 1999, Ware, 2004).

title Problem Framing in Multiple Settings
source International Journal of Architectural Computing vol. 2 - no. 4, 444-460
summary This study offers an insight to architectural students' problem framing activities using digital and paper media. The role of problem framing in design processes and its contribution to design learning has been studied by others. Here, we investigate the effects of media on framing activities. Laboratory experiments were conducted to investigate problem framing under three settings, namely online co-located, online remote and paper-based co-located. Student pairs were asked to spend forty minutes in solving collaboratively a wicked design problem. The results show that problem framing activities are significantly different in the online remote setting compared to those in the two co-located settings. We find more density of framing activities happened in the online remote setting than in the other two settings while there is no significant difference between online co-located and paper-based colocated settings.

summary In order to improve pedagogical effectiveness, this study aims at gaining an insight on architectural students’ problem framing activities using digital versus paper media. The role of problem framing in design process and its contribution to design learning has been variously studied. Laboratory experiments were conducted to investigate the role of problem framing under three settings namely online co-located, online remote and paper-based co-located. Students were asked to spend 40 minutes in solving a wicked design problem collaboratively. The results show that in the online remote setting the activities of problem framing are significantly different compared to those in the other two co-located settings. We find more density of framing activities happened in the online remote setting than in the other two settings. We also find there is no significant difference of problem framing between online co-located and paper-based colocated settings. Through this study we suggest that multiple design tools need to be considered to support design learning and teaching.

summary Urban design involves coordination and communication for collecting consensus among citizens and developing the design strategy and spatial program. While these are web-based systems for representing the real world actions, there is lack of human interaction for receiving feedbacks during the process. Therefore, the purpose of this study is to introduce the agents into the participatory design process (PDP) based on scenarios. This paper has developed a webbased system prototype to demonstrate how the agent can interact with users and how the interface facilitates incremental design. We present a participatory design project in an old street to illustrate how the Scenario-Based Agent System (SBAS) model functions in a real application. Meanwhile, four issues will be discussed in regarding with building a learning interaction agent as an actor.

summary This paper presents a pedagogical approach to explore the relationships between time and space by using digital media. Based on a pedagogical model called e-Space proposed by Lai (2004), we apply motion as a spatial issue to approach this study. Through integrating with the characteristics of digital media, students are encouraged to evolve architectural space and form by decomposing, re-organizing, interpreting and realizing the spatial composition. Simultaneously, diverse digital media applications integrated with design thinking in a design process enables students to bridge two design spaces - physical and virtual. This process introduces the students to a new approach of design-creation and form finding. Finally, we use an advanced digital media course as an example to understand the impacts of the pedagogical approach. The students’ outcomes are also reported in this paper

summary We are currently exploring the concept of mediated discourse in relation to an architectonic intervention and urban transformation project in an educational project and elective course. Led by faculty and artists, students are offered the ability to experiment with various media in the design and development of a multidisciplinary discourse. A web-based elearning environment also allows the students’ activities to form part of a larger discourse that takes place among all participants, including the public. In this paper, we describe the concept of mediated discourse and the various dimensions we distinguish, we present the educational project and its various aspects and participants’ roles, we consider the internationalisation of this educational project in a future instance of the course, and we describe the characteristics of the web environment in the context of an educational and software development project for a multimedia learning environment to support group work and discourse.

summary Decisions taken at early stages of building design have a significant effect on the planning steps for the entire lifetime of the project as well as the performance of the building throughout its lifecycle (MacLeamy 2004). Building Information Modelling (BIM) could bring forward and enhance the planning and decision-making processes by enabling the direct reuse of data hold by the model for diverse analysis and simulation tasks (Borrmann et al. 2015). The architect today besides a couple of simplified simulation tools almost exclusively uses his know-how for evaluating and comparing design variants in the early stages of design. This paper focuses on finding new ways to facilitate the use of analytical and simulation tools during the important early phases of conceptual building design, where the models are partially incomplete. The necessary enrichment and proper detailing of the design model could be achieved by means of dialogue-based interaction concepts with analytical and simulation tools through adaptive detailing strategies. This concept is explained using an example scenario for design process. A generic description of the aimed dialog-based interface to various simulation tools will also be discussed in this paper using an example scenario.

summary This paper presents an account of our research and development of processes providing seamless transition from design to fabrication. The narrative of our design, development, and prototyping experi¬ments spans seven years, including our current project, the Trusset software/structural system. Trusset is a combined building system and agent-based software design tool. The building system is based on a differential space-truss designed for fabrication entirely with computer numerically controlled (CNC) linear cutting devices, such as laser cut¬ters or three-axis mills. The software component is a set of agent-based design tools for developing surfaces and envelopes formally suitable to be built using the space-truss structure. Developed in parallel, the soft¬ware and building components combine within the Trusset system to provide a seamless pipeline from design to fabrication and assembly. The story of the development of software components and structural system, leading to the Trusset, act as a means of discussing the larger issues framing the research: the potential pitfalls and benefits of design and fabrication integration via the computer.

title SGML: a meta-language for shape grammars
source PhD dissertation, Department of Architecture, Massachusetts Institute of Technology, Cambridge, Mass
summary A shape grammar develops a drawing through a series of transformations by repeatedly applying if-then rules. Although the rules can be designed, in principle, to construct any type of drawing, the drawings they construct may not necessarily develop in the manner intended by the designer of the grammar. In this thesis, I introduce a shape grammar meta-language that adds power to grammars based on the shape grammar language. Using the shape grammar meta-language, the author of a grammar can: (1) explicitly determine the sequence in which a set of rules is applied; (2) restrict rule application through a filtering process; and (3) use context to guide the rule matching process, all of which provide a guided design experience for the user of the grammar. Three example grammars demonstrate the effectiveness of the meta-language. The first example is the Bilateral Grid grammar which demonstrates how the meta-language facilitates the development of grammars that offer users multiple design choices. The second grammar is the Hexagon Path grammar which demonstrates how the metalanguage is useful in contexts other than architectural design. The third and most ambitious example is the Durand grammar which embodies the floor plan design process described in Précis of the Lectures of Architecture, written by JNL Durand, an eighteenth century architectural educator. Durand's floor plan design process develops a plan through a series of transformations from grid to axis to parti to wall. The corresponding Durand grammar, which consists of 74 rules and 15 macros organized into eight stages, captures Durand's ideas and fills in gaps in Durand's description of his process. A key contribution of this thesis is the seven descriptors that constitute the meta-language. The descriptors are used in grammar rules: (1) to organize a set of rules for the user to choose from; (2) to group together a series of rules; (3) to filter information in a drawing; (4) to constrain where a rule can apply; and (5) to control how a rule is applied. The end result is a language that allows the author to create grammars that guide users by carefully controlling the design process in the manner intended by the author.

title No More Fear or Doubt: Electronic Architecture in Architectural Education
source eDesign in Architecture: ASCAAD's First International Conference on Computer Aided Architectural Design, 7-9 December 2004, KFUPM, Saudi Arabia
summary Operating electronic and Internet worked tools for Architectural education is an important, and merely a prerequisite step toward creating powerful tele-collabortion and tele-research in our Architectural studios. The design studio, as physical place and pedagogical method, is the core of architectural education. The Carnegie Endowment report on architectural education, published in 1996, identified a comparably central role for studios in schools today. Advances in CAD and visualization, combined with technologies to communicate images, data, and “live” action, now enable virtual dimensions of studio experience. Students no longer need to gather at the same time and place to tackle the same design problem. Critics can comment over the network or by e-mail, and distinguished jurors can make virtual visits without being in the same room as the pin-up—if there is a pin-up (or a room). Virtual design studios (VDS) have the potential to support collaboration over competition, diversify student experiences, and redistribute the intellectual resources of architectural education across geographic and socioeconomic divisions. The challenge is to predict whether VDS will isolate students from a sense of place and materiality, or if it will provide future architects the tools to reconcile communication environments and physical space.

summary Designing is largely a process of (inter)active imaging. The evolvement of a design concept from preliminary design proposal towards spatial and material environment generally follows an uncertain path through uncharted landscape; a journey of exploration which requires both rational and creative consideration, frequently involving the interchange of information within a design team and collaboration with representatives from different contributing disciplines. Designs are conceived, worked out and specified step by step (roughly speaking from ‘rough to fine’) in iterative design ‘loops’. All the time the designer tries to determine which ‘course’ should be taken, by considering reference material, by reflecting on conceptions developed previously and by generating specific options aimed at furthering the ‘concretisation’ of the end product. In the course of such a trajectory, visual information is continually being developed, selected, tested, and subsequently either discarded or perfected. From early times architects have been considered not only as knowledgeable ‘experts’ in the field of building as a craft, but also as ‘creative directors’ of such development processes. The architect should be capable of not only conjuring up visions of the future spatial and material form of the building, but also of conveying these to the other ‘actors’ involved in the initiation and building process. Such ‘sharing’ of information is necessary in order to generate sufficient understanding, consensus, enthusiasm, as well as means. To become more than ‘figments of the imagination’, the designer’s ideas need to be ‘pinned down’ (even if they are not yet entirely finished) and communicated by using some form of reliable – and preferably readable – ‘language’ for design development and communication.

summary In this paper an object-based CAD programming is used to take advantage of standardization to handle the schematic design, sizing, layout for services in a building ceiling void. From the specification of the building 3D model, our software proceeds through different steps; from the determination of the standard number and size of fan coils to the generation of 3D solutions. In order to deal with more complex geometry and larger problems, we have used a hybrid approach: Case Based Reasoning (CBR) within Constraint Satisfaction Problem (CSP) approaches. In practice, engineers in building services use previous solutions and adapt them to new problems. CBR mirrors this practical approach and does help us to deal with increasingly complex geometry effectively, and meanwhile CSP has been used for layout adaptation. The results have shown that it is possible to define and implement standard solutions to produce designs comparable with current practice. The benchmarking exercise has underlined many advantages and made some suggestions for further development. This project is funded by The Engineering and Physical Sciences Research Council (EPSRC) in UK.

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 Presently, only a small percentage of people in the world typically hire an architect to design and build a home which is tailored to their preference. Besides the architect’s fee, clients also need to wait an interminable time for design and construction. Factory-made prefabricated housing systems tried to solve this problem previously. However, most pioneers failed to address the issues of variability and individual needs (Kieran & Timberlake, 2004). Plants closed because they produced more than the market demand, and prefabricated housing provided less flexibility than the traditional stick-built housing. The advanced digital technology makes it possible to communicate design ideas and concepts to others more effectively. The project delivery process leads itself to customization, embodying principles of lean production (Pine, 1993), flexible computer-integrated design interaction with clients, and reduced cycle times; all effecting rapid response between consumers and producers.

summary This paper considers high-level, architecturally oriented repre­sentations, like Building Information Models (BIMs), and examines the difficulty of integrating analyses with such representations. Structural analysis is selected as a sample analysis domain, and is examined by integrating a structural analysis into the test implementation of a program that utilizes architecturally oriented elements. A fundamental problem is found to be that architecturally oriented elements are inappropriate for structural analysis. Methods for sequentially analyzing architectural elements are discussed, but are found to be inadequate. Accurate analysis requires analyzing the entire structure at once using a representation specific to structural analysis. A method for generating a structural representation based on the architectural representation is discussed, but the process is not simple. The process is complicated by the fact that architectural elements and structural elements do not correspond in a one-to-one or even a one-to-many manner. An accurate structural representation may even require semi-fictitious elements not corresponding to actual physical components. These findings are believed to be true for other analysis domains, as well.
