summary The virtual reconstruction of the archeological site of Madinat al-Zahra. in Córdoba (Spain) has permitted a new approach to the study and comprehension of this palatine city as well as to the typologies of Islamic architecture in Al-Andalus during the 10th century. Starting from fieldwork and from a photogrammetric survey of the site, the digital model has become a highly qualified tool in the research process. Through virtual navigation, it allows to learn new aspects about spatial configuration of this characteristic constructions that configure the basis for the development of further architectures during the following centuries. Furthermore, being conscious that knowledge is basic for cultural heritage preservation, this 3D reconstruction model is an important instrument for general dissemination and for implementing a visit to this significant case of Islamic architecture in Spain.

title Something 's gotta give' architectural animations
source SIGraDi 2004 - [Proceedings of the 8th Iberoamerican Congress of Digital Graphics] Porte Alegre - Brasil 10-12 november 2004
summary Architectural animations are like Harry Langer, a fifty-something entertainment mogul played by best actor nominee Jack Nicholson in the film Something.s Gotta Give. been surrounded by plenty of pathetic spiritless gimmicks. And, like Harry in the film, they have suffered a heart attack. Harry did not die. Architectural animations are still around, barely. Something.s wrong with them. When Harry begins to recover, he.s surprised to find himself growing fond of a woman his own age (played by best actress nominee Dianne Keaton). This is precisely what should happen to architectural animations. They need to come to terms with more mature attitudes and approaches. This paper presents a new and different approach to architectural animations. In ninety nine percent of the cases, architectural animations have been produced at the end of the design process, just when architects or architecture students are ready to present their schemes to an audience or client group. All design decisions have been made. All aspects of the architectural solutions have been set. Tectonic qualities, lighting schemes, construction approaches, everything has been cast in stone. The animation is simply shown as a public relations gesture to broadcast to the audience that the design team is digitally savvy and uses the latest technologies. The proposition contained herein is that animations be used throughout the design process, that is, from beginning to end.

title Toward New Wall Systems: Lighter, Stronger, Versatile

summary Recent developments in digital technologies and smart materials have created new opportunities and are suggesting significant changes in the way we design and build architecture. Traditionally, however, there has always been a gap between the new technologies and their applications into other areas. Even though, most technological innovations hold the promise to transform the building industry and the architecture within, and although, there have been some limited attempts in this area recently; to date architecture has failed to utilize the vast amount of accumulated technological knowledge and innovations to significantly transform the industry. Consequently, the applications of new technologies to architecture remain remote and inadequate. One of the main reasons of this problem is economical. Architecture is still seen and operated as a sub-service to the Construction industry and it does not seem to be feasible to apply recent innovations in Building Technology area. Another reason lies at the heart of architectural education. Architectural education does not follow technological innovations (Watson 1997), and that “design and technology issues are trivialized by their segregation from one another” (Fernandez 2004). The final reason is practicality and this one is partially related to the previous reasons. The history of architecture is full of visions for revolutionizing building technology, ideas that failed to achieve commercial practicality. Although, there have been some adaptations in this area recently, the improvements in architecture reflect only incremental progress, not the significant discoveries needed to transform the industry. However, architectural innovations and movements have often been generated by the advances of building materials, such as the impact of steel in the last and reinforced concrete in this century. There have been some scattered attempts of the creation of new materials and systems but currently they are mainly used for limited remote applications and mostly for aesthetic purposes. We believe a new architectural material class is needed which will merge digital and material technologies, embedded in architectural spaces and play a significant role in the way we use and experience architecture. As a principle element of architecture, technology has allowed for the wall to become an increasingly dynamic component of the built environment. The traditional connotations and objectives related to the wall are being redefined: static becomes fluid, opaque becomes transparent, barrier becomes filter and boundary becomes borderless. Combining smart materials, intelligent systems, engineering, and art can create a component that does not just support and define but significantly enhances the architectural space. This paper presents an ongoing research project about the development of new class of architectural wall system by incorporating distributed sensors and macroelectronics directly into the building environment. This type of composite, which is a representative example of an even broader class of smart architectural material, has the potential to change the design and function of an architectural structure or living environment. As of today, this kind of composite does not exist. Once completed, this will be the first technology on its own. We believe this study will lay the fundamental groundwork for a new paradigm in surface engineering that may be of considerable significance in architecture, building and construction industry, and materials science.

title Using a Spatial Microsimulation Decision Support System for Policy Scenario Analysis
source Van Leeuwen, J.P. and H.J.P. Timmermans (eds.) Recent Advances in Design & Decision Support Systems in Architecture and Urban Planning, Dordrecht: Kluwer Academic Publishers, ISBN: 1-4020-2408-8, p. 177-191
summary This paper discusses the potential of a spatial microsimulation-based decision support system for policy analysis. The system can be used to describe current conditions and issues in neighbourhoods, predict future trends in the composition and health of neighbourhoods and conduct modelling and predictive analysis to measure the likely impact of policy interventions at the local level. A large dynamic spatial micro-simulation model is being constructed for the population of Leeds (approximately 715,000 individuals) based on spatial microsimulation techniques in conjunction with a range of data, including 2001 Census data for Output Areas and sample data from the British Household Panel Survey. The project has three main aims as follows: (i) to develop a static microsimulation model to describe current conditions in Leeds; (ii) to enable the performance of ‘What if?’ analysis on a range of policy scenarios; and (iii) to develop a dynamic microsimulation model to predict future conditions in Leeds under different policy scenarios. The paper reports progress in meeting the above aims and outlines the associated difficulties and data issues. One of the significant advantages of the spatial microsimulation approach adopted by this project is that it enables the user to query any combination of variables that is deemed desirable for policy analysis. The paper will illustrate the software tool being developed in the context of this project that is capable of carrying out queries of this type and of mapping their results. The decision support tool is being developed to support policy-makers concerned with urban regeneration and neighbourhood renewal.

title Crowd Modeling and Simulation

summary The paper introduces a Multi Agent Systems (MAS) approach to crowd modelling and simulation, based on the Situated Cellular Agents (SCA) model. This is a special class of Multilayered Multi Agent Situated System (MMASS), exploiting basic elements of Cellular Automata. In particular SCA model provides an explicit spatial representation and the definition of adjacency geometries, but also a concept of autonomous agent, provided with an internal architecture, an individual state and behaviour. The latter provides different means of space-mediated interaction among agents: synchronous, between adjacent agents, and asynchronous among at-a-distance entities. Heterogeneous entities may be modelled through the specification of different agent types, defining different behaviours and perceptive capabilities. After a brief description of the model, its application to simple crowd behaviours will be given, and an application providing the integration of a bidimensional simulator based on this model and a 3D modelling application (3D Studio) will also be described. The adoption of this kind of system allows the specification and simulation of an architectural design with reference to the behaviour of entities that will act in it. The system is also able to easily produce a realistic visualization of the simulation, in order to facilitate the evaluation of the design and the communication with involved decision-makers. In fact, while experts often require only abstract and analytical results deriving from a quantitative analysis of simulation results, other people involved in the decision-making process related to the design may be helped by qualitative aspects better represented by other forms of graphical visualization.

summary This paper deals with “Spirospaces”. These are a conversion to the third dimension of the two dimensional geometric entities called “Spirolaterals”.

Abelson, Harold, diSessa and Andera (1968) gave the first rules concerning Spirolaterals. To obtain a Spirolateral from a set of straight lines, the first of them must be one unit long and the following must be incremented one unit at each step, at the same time that they turn in a constant direction. Odds (1973) establish the variation of the rotation direction, either to the left or the right. However, he did not give a mathematical relation able to calculate open Spirolaterals. Krawczyk (2001) developed a computer program that generates Spirolaterals following the method suggested by Abelson. These are Spirolaterals obtained by enumeration without a predictive mathematical formula. Krawczyc went farther proposing Spirolaterals based in curved lines. He pointed out that there are a variety of spirolateral forms that have architectural potentiality. Following this, the architectural potentiality of Spirolaterals is the basis of this paper.

To take advantage of that potentiality a computer program was implemented to generate spatial configurations based in Spirolaterals. When a third dimension is given to the Spirolaterals they become Spirospaces. These new entities need spatial and design parameters to be useful for architectural purposes. Barrionuevo and Borsetti (2001) gave results about that work establishing the concept of Spirospaces.

The aim of this paper is to describe a work directed to improve rules and procedures concerning Spirospaces. It is expected that these procedures governed by the proposed rules can be employed as tools during the early steps in the architectural design process.

In this work some aspects concerning Spirospaces are considered. First, Spirolaterals are presented as the predecessors of Spirospaces. Second, Spirospaces are defined, together with their structural parameters. Architectural modeling is studied at the light of two special elements of the Spirospaces: Interstitial spaces and Object spaces. Next, a computer program is presented as the appropriate tool to model configurations having architectural potentiality. Finally, the results obtained running the computer program are analyzed to determine their possible use as architectural forms. Several graphic illustrations are presented showing steps going from the exploration of spatial alternatives to the selection of a specific configuration to be developed.

It is expected that the described computer program could be employed as a design aid tool. As the operation of the program generates a variety of spaces able to dwell architectural objects, it eases the search of configurations suitable to specific functions. The results obtained have the possibility of being exported to computer graphic applications able to add materials, lights and cameras.

title Spirospaces in Architectural Design
source eDesign in Architecture: ASCAAD's First International Conference on Computer Aided Architectural Design, 7-9 December 2004, KFUPM, Saudi Arabia
summary The proposal of this paper is to present "Spirospaces" and their utility in Architectural Design, exploring their relation with other geometrical disciplines such as knot theory, tiling and patterns generation. A spirospace is a geometrical entity generated from the spatial interpretation of a "Spirolateral", a well known bidimentional entity. A computer program to generate spirospaces configurations is presented and demonstrated with several examples. This is complemented with the exposition of the mathematical framework that supports closed spirospaces generation.

summary This paper is reporting on a research project undertaken jointly between the University of New South Wales (UNSW) and the NSW Department of Housing (DoH) to develop a Spatial Decision Support System (SDSS) to assist planning, management and evaluation in areas of high public housing concentration. In the paper we will describe the development of the SDSS, the specific spatial problems challenging the DoH and the potential for the system to incorporate a range of social, financial and physical data, both internal and from other sources, for interaction and presentation in a three dimensional environment. The prototype SDSS attempts to address the specific challenges of providing better service for clients of the DoH. An information audit and survey has been conducted of the department’s resources and needs. Issues identified include the management of high-rise and superlot areas, crime mapping, community interactivity, internal and intergovernmental information sharing, interoperability and maintaining confidentiality and security of data. Interactive 3D visualisation of the model is facilitated by use of the 3map free geospace platform. Use of open source code and open standards such as X3D for 3D graphics interchange allow the project to explore advanced visualisation techniques while ensuring interoperability and data longevity.

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.

summary The computer in architectural design has shifted from its role as a merely representational device to that of a tool for instrumentalized simulation and fabrication. The desire to make buildings look like a rendering, or to produce photo-realistic images and walkthroughs has given way to an opening of the potentials of software to assist the designer with managing complex geometries, parametric organizational diagrams, structural analysis, and integrated building systems. Simulation has become the means by which virtual space becomes more than just a mirror of reality. It becomes the space within which different potential realities can be tested and evaluated before they are materially implemented. In architecture, information derived from material constraints to site conditions can be constantly fed into the computer models to provide an accurate update, which in turn introduces feedback into the overall design, and change can then be registered in the detail.

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 Understanding scale is a major concern and a condition of working in the field of architecture and urban design. The project described in this case origins from Blauwe Koffer, a method developed in the 80’s by the Dutch architects Dolf Dobbelaar and Paul de Vroom. The method is devoted to analysis of form and function of important architectural and urban design projects in the last century and is a flexible model for searching architectural solutions at an early stage of a project. In the paper I will describe how a group of faculty transformed the Blauwe Koffer into a digital method serving as an introduction to urban design in the second year curriculum. The project introduced topics of modern urbanism defined as cityscapes. Through a series of mapping analysis the students studied variations of scale, extension, volume, density, borders, overlaps, bricollage, diversity etc. The students were required to do analysis in the form of a matrix of 6 x 7 cells. Categories in the analysis were three scales of figure / ground studies, bricollage and studies of the urban raster. DataTown was a particular category inspired by MVRDV. The project data derived from digital maps, and project presentations in books and magazines. At second year the students are assigned to do digital projects as a part of the curriculum and the students are required to have their own computer. The project was the first digital assignment in studio and previous computer courses and skills were limited to a one-week course in desktop publishing. The CityScape project was a successful experience in integrating computation in studio, in group work and in analysis of modern urbanism. The paper will show some of the projects and discuss the assignment as a part of the implementation of an IT-strategy.

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.

title Zero-waste, Flat Pack Truss Work: An Investigation of Responsive Structuralism

summary The direct and rapid connections between scripting, modeling and prototyping allow for investigations of computation in fabrication. The manipulation of planar materials with two-dimensional CNC cuts can easily create complex and varied forms, volumes, and surfaces. However, the bulk of research on folding using CNC fabrication tools is focused upon surfaces, self-supporting walls and shell structures, which do not integrate well into more conventional building construction models.This paper attempts to explain the potential for using folding methodologies to develop structural members through a design-build process. Conventional building practice consists of the assembly of off-the-shelf parts. Many times, the plinth, skeleton, and skin are independently designed and fabricated, integrating multiple industries. Using this method of construction as an operative status quo, this investigation focused on a single structural component: the truss. A truss is defined as: “A triangulated arrangement of structural members that reduces nonaxial external forces to a set of axial forces in its members.” (Allen and Iano 2004)Using folding methodologies and sheet steel to create a truss, this design investigation employed a recyclable and prolific building material to redefine the fabrication of a conventional structural member. The potential for using digital design and two-dimensional CNC fabrication tools in the design of a foldable truss from sheet steel is viable in the creation of a flat-packed, minimal waste structural member that can adapt to a variety of aesthetic and structural conditions. Applying new methods to a component of the conventional ‘kit of parts’ allowed for a novel investigation that recombines zero waste goals, flat-packing potential, structural expression and computational processes.

source Van Leeuwen, J.P. and H.J.P. Timmermans (eds.) Developments in Design & Decision Support Systems in Architecture and Urban Planning, Eindhoven: Eindhoven University of Technology, ISBN 90-6814-155-4, p. 193-208
summary The transfer of knowledge between planners and business decision makers can be improved when planners combine traditional visualizations with business knowledge visualizations. Today architects and urban planners use visualization methods such as sketches, diagrams, drawings, renderings, models and animations to illustrate their projects. While spending an enormous amount of time to illustrate a project, almost no time is used to illustrate business relevant information that decision makers need (i.e., revenue models, risks, return on investments, project phases). Consequences are information overload, misinterpretation or even misuse of information. Juxtaposing the visualizations that planners and decision makers use reveals a major gap: Both groups use different visualization types and are not familiar with the visualization types of each other. This paper stresses the importance to expand the visualization types of planners with business knowledge visualizations. First, it discusses the functioning of visual representations for the transfer of knowledge. Second, it introduces a general knowledge visualization framework. Third, it illustrates examples from an innovative office that improved knowledge transfer with decision makers in urban planning projects. We found that combining traditional visualizations with business knowledge visualizations reduces the information overload, prevents misinterpretation, increases the information quality, improves communication and as a consequence improves decision making. We found that decision makers pay extra for these visualization types, which therefore is a new source of income for planners. The results have implications for the education of future architects.

title Mindful Spaces: Computational Geometry and the Conceptual Spaces in which Designers Operate
source International Journal of Architectural Computing vol. 5 - no. 4, pp. 611-624
summary Combinatorial computational geometry, while dealing with geometric objects as discrete entities, provides the means both to analyse and to construct relationships between these objects and relate them to other non-geometrical entities. This paper explores some ways in which this may be used in design through a review of six, one-semester-long design explorations by undergraduate and postgraduate students in the Flexible Modeling for Design and Prototyping course between 2004 and 2007. The course focuses on using computational geometry firstly to construct topologically defined design models based on graphs of relationships between objects (parametric design,) and concurrently to output physical prototypes from these "flexible models"(an application of numerical computational geometry). It supports students to make early design explorations. Many have built flexible models to explore design iterations for a static spatial outcome. Some have built models of real time responsive dynamic systems. In this educational context, computational geometry has enabled a range of design iterations that would have been challenging to uncover through physical analogue means alone. It has, perhaps more significantly, extended the students' own concept of the space in which they design.

title How to Construct an Audience in Collaborative Design - The Relationship Among which Actors in the Design Process
source Architecture in the Network Society [22nd eCAADe Conference Proceedings / ISBN 0-9541183-2-4] Copenhagen (Denmark) 15-18 September 2004, pp. 426-434
summary The features of complexity in architectural design have now been clarified. Complexity, intrinsic in architectural work, has increased in recent years as in all other fields of human endeavour – social, economic and cultural. In the specific case of architectural design, the most significant factors in this regard consist of the large number of actors, the numerous disciplines involved, technological innovation, regulations and rules governing the design process and the various different design aims. In order to address this complex of problems, long-term research based on the Collaborative Design paradigm, CD, is now being carried out. In it, thanks to the reciprocal exchange of information, the complementary nature of the knowledge possessed by the various actors, and the contemporary nature of the design action by the various actors on the same components, positive effects are exerted on the design as a whole. The latter thus gains in coherence and in improved integration among the design solutions proposed by the various actors. In CD all the actors are involved from the outset of the design work and are helped by distributed Knowledge Bases (KBs) and Intelligent Assistants (IAs). In this case it may happen that information and knowledge automatically exchanged among KBs (through the IAs) are excessive and/or not addressed to the right actors. How can information redundancy be avoided, and how can the flow of information sent over the network be controlled? The present paper introduces and defines the concept of „Audience“, that is, the group of actors to which it is permitted to send information concerning non respected requirements and the „reduced Audience“ to which to send the knowledge needed to overcome the difficulties encountered.
