title AVALIAÇÃO DO USO DA SIMULAÇÃO COMPUTACIONAL EM PROJETOS DE ILUMINAÇÃO ARTIFICIAL (Evaluation of the Use of Computer Simulation for Artificial Illumination Projects)
source SIGraDi biobio2001 - [Proceedings of the 5th Iberoamerican Congress of Digital Graphics / ISBN 956-7813-12-4] Concepcion (Chile) 21-23 november 2001, pp. 95-97
summary This paper tries to evaluate the quantitative e qualitative aspects of the uses of the computational simulation for the analysis of enclosed environments light designs, and its feasibility in teaching in Architectural and Urbanism courses. The importance of this paper is associated with the determining of the illumination levels and its effects. Simulations were made with the Lightscape software in a specific room and their results were compared with the experimental measurements taken in that place. From this comparison it was possible to make the analysis of the software characteristics and to evaluate the advantages or disadvantages of its uses. The results confirm its feasibility as a tool for illumination simulation and its adequate uses in the teaching of environmental comfort. The good correlation achieved in visual effects derived from the lighting design and also the information of values related to illuminance and luminance for the simulated space support this affirmative.

title Physical and Digital Media Strategies For Exploring ‘Imagined’ Realities of Space, Skin and Light
source Thresholds - Design, Research, Education and Practice, in the Space Between the Physical and the Virtual [Proceedings of the 2002 Annual Conference of the Association for Computer Aided Design In Architecture / ISBN 1-880250-11-X] Pomona (California) 24-27 October 2002, pp. 13-23
summary This paper will discuss an unconventional methodology for using physical and digital media strategies ina tightly structured framework for the integration of Environmental Control Systems (ECS) principles intoa third year design studio. An interchangeable use of digital media and physical material enabledarchitectural explorations of rich tactile and luminous engagement.The principles that provide the foundation for integrative strategies between a design studio and buildingtechnology course spring from the Bauhaus tradition where a systematic approach to craftsmanship andvisual perception is emphasized. Focusing particularly on color, light, texture and materials, Josef Albersexplored the assemblage of found objects, transforming these materials into unexpected dynamiccompositions. Moholy-Nagy developed a technique called the photogram or camera-less photograph torecord the temporal movements of light. Wassily Kandinsky developed a method of analytical drawingthat breaks a still life composition into diagrammatic forces to express tension and geometry. Theseschematic diagrams provide a method for students to examine and analyze the implications of elementplacements in space (Bermudez, Neiman 1997). Gyorgy Kepes's Language of Vision provides a primerfor learning basic design principles. Kepes argued that the perception of a visual image needs aprocess of organization. According to Kepes, the experience of an image is "a creative act ofintegration". All of these principles provide the framework for the studio investigation.The quarter started with a series of intense short workshops that used an interchangeable use of digitaland physical media to focus on ECS topics such as day lighting, electric lighting, and skin vocabulary tolead students to consider these components as part of their form-making inspiration.In integrating ECS components with the design studio, an nine-step methodology was established toprovide students with a compelling and tangible framework for design:Examples of student work will be presented for the two times this course was offered (2001/02) to showhow exercises were linked to allow for a clear design progression.

title Strategy on applying computational fluid dynamic for building performance evaluation
source Automation in Construction 10 (3) (2001) pp. 327-335
summary Predicting and evaluating building performance plays an important role in the training of responsible architects. Building performance includes issues such as: structural stability, acoustic quality, natural lighting, thermal comfort, and ventilation and indoor air quality. These types of analyses are often laborious, non-intuitive, and non-graphical. As a result, these important issues do not arouse the enthusiasm of architecture students or building professionals. The Chinese University of Hong Kong (CUHK) research team proposes to explore and develop a long-term strategy to apply scientific visualization on teaching and research in environmental technology and building performance. This paper presents the development process and results of research projects for applying computational fluid dynamics (CFD) on building performance evaluation. CFD On-line Teaching project's aim is to develop a web-based training course for architecture students to apply CFD simulation on design problem solving. Each lesson not only illustrates basic principles regarding airflow in the building design, it also contains CFD sample files with predefined flow cells for students to test different concepts. GiLin Temple project's aim is to apply CFD simulation on investigating the wind resistance of Tong Dynasty heavy timber structure. Airflow information generated in the project includes the visual representation of the pressure distribution and velocity field on all slices through the temple, and the tracking of particles as they flow around or through a building. The China housing residential airduct study focuses on simulating the indoor airflow regarding the airduct design of China Experimental Urban Housing Scheme. The visual representation of the pressure distribution and velocity field in the airducts provides vital information for helping China Housing Research Center improve the current design.

title Digital Architecture in CAD studio and Internet-based competition
source AVOCAAD - ADDED VALUE OF COMPUTER AIDED ARCHITECTURAL DESIGN, Nys Koenraad, Provoost Tom, Verbeke Johan, Verleye Johan (Eds.), (2001) Hogeschool voor Wetenschap en Kunst - Departement Architectuur Sint-Lucas, Campus Brussel, ISBN 80-76101-05-1
summary Architectural design has been changing because of the vast and creative use of computer in different ways. From the viewpoint of designing itself, computer has been used as drawing tools in the latter phase of design (Mitchell 1977; Coyne et al. 1990), presentation and simulation tools in the middle phase (Liu and Bai 2000), and even critical media which triggers creative thinking in the very early phase (Maher et al. 2000; Liu 1999; Won 1999). All the various roles that computer can play have been adopted in a number of professional design corporations and so-called computer-aided design (CAD) studio in schools worldwide (Kvan 1997, 2000; Cheng 1998). The processes and outcomes of design have been continuously developing to capture the movement of the computer age. However, from the viewpoint of social-cultural theories of architecture, the evolvement of design cannot be achieved solely by designers or design processes. Any new idea of design can be accepted socially, culturally and historically only under one condition: The design outcomes could be reviewed and appreciated by critics in the field at the time of its production (Csikszentmihalyi 1986, 1988; Schon and Wiggins 1992; Liu 2000). In other words, aspects of design production (by designers in different design processes) are as critical as those of design appreciation (by critics in different review processes) in the observation of the future trends of architecture.Nevertheless, in the field of architectural design with computer and Internet, that is, so-called computer-aided design computer-mediated design, or internet-based design, most existing studies pay more attentions to producing design in design processes as mentioned above. Relatively few studies focus on how critics act and how they interact with designers in the review processes. Therefore, this study intends to investigate some evolving phenomena of the interaction between design production and appreciation in the environment of computer and Internet.This paper takes a CAD studio and an Internet-based competition as examples. The CAD studio includes 7 master's students and 2 critics, all from the same countries. The Internet-based competition, held in year 2000, includes 206 designers from 43 counties and 26 critics from 11 countries. 3 students and the 2 critics in the CAD studio are the competition participating designers and critics respectively. The methodological steps are as follows: 1. A qualitative analysis: observation and interview of the 3 participants and 2 reviewers who join both the CAD studio and the competition. The 4 analytical criteria are the kinds of presenting media, the kinds of supportive media (such as verbal and gesture/facial data), stages of the review processes, and interaction between the designer and critics. The behavioral data are acquired by recording the design presentation and dialogue within 3 months. 2. A quantitative analysis: statistical analysis of the detailed reviewing data in the CAD studio and the competition. The four 4 analytical factors are the reviewing time, the number of reviewing of the same project, the comparison between different projects, and grades/comments. 3. Both the qualitative and quantitative data are cross analyzed and discussed, based on the theories of design thinking, design production/appreciation, and the appreciative system (Goodman 1978, 1984).The result of this study indicates that the interaction between design production and appreciation during the review processes could differ significantly. The review processes could be either linear or cyclic due to the influences from the kinds of media, the environmental discrepancies between studio and Internet, as well as cognitive thinking/memory capacity. The design production and appreciation seem to be more linear in CAD studio whereas more cyclic in the Internet environment. This distinction coincides with the complementary observations of designing as a linear process (Jones 1970; Simon 1981) or a cyclic movement (Schon and Wiggins 1992). Some phenomena during the two processes are also illustrated in detail in this paper.This study is merely a starting point of the research in design production and appreciation in the computer and network age. The future direction of investigation is to establish a theoretical model for the interaction between design production and appreciation based on current findings. The model is expected to conduct using revised protocol analysis and interviews. The other future research is to explore how design computing creativity emerge from the process of producing and appreciating.

title A Quantitative Method to Compare the Impact of Design Mediums on the Architectural Ideation Process.
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. 539-556.
summary If we compare the architectural design process to a black box system, we can assume that we now know quite well both inputs and outputs of the system. Indeed, everything about the early project either feasibility studies, programming, context integration, site analysis (urban, rural or natural), as well as the integration of participants in a collaborative process can all be considered to initiate and sustain the architectural design and ideation process. Similarly, outputs from that process are also, and to some extent, well known and identifiable. We are referring here, among others, to the project representations or even to the concrete building construction and its post-evaluation. But what about the black box itself that produces the ideation. This is the question that attempts to answer the research. Currently, very few research works linger to identify how the human brain accomplishes those tasks; how to identify the cognitive functions that are playing this role; to what extent they operate and complement each other, and among other things, whether there possibly a chain of causality between these functions. Therefore, this study proposes to define a model that reflects the activity of the black box based on the cognitive activity of the human brain. From an extensive literature review, two cognitive functions have been identified and are investigated to account for some of the complex cognitive activity that occurs during a design process, namely the mental workload and mental imagery. These two variables are measured quantitatively in the context of real design task. Essentially, the mental load is measured using a Bakan's test and the mental imagery with eyes tracking. The statistical software G-Power was used to identify the necessary subject number to obtain for significant variance and correlation result analysis. Thus, in the context of an exploratory research, to ensure effective sample of 0.25 and a statistical power of 0.80, 32 participants are needed. All these participants are students from 3rd, 4th or 5th grade in architecture. They are also very familiar with the architectural design process and the design mediums used, i.e., analog model, freehand drawing and CAD software, SketchUp. In three experimental sessions, participants were asked to design three different projects, namely, a bus shelter, a recycling station and a public toilet. These projects were selected and defined for their complexity similarity, taking into account the available time of 22 minutes, using all three mediums of design, and this in a randomly manner to avoid the order effect. To analyze the two cognitive functions (mental load and mental imagery), two instruments are used. Mental imagery is measured using eye movement tracking with monitoring and quantitative analysis of scan paths and the resulting number and duration of participant eye fixations (Johansson et al, 2005). The mental workload is measured using the performance of a modality hearing secondary task inspired by Bakan'sworks (Bakan et al.; 1963). Each of these three experimental sessions, lasting 90 minutes, was composed of two phases: 1. After calibrating the glasses for eye movement, the subject had to exercise freely for 3 minutes while wearing the glasses and headphones (Bakan task) to get use to the wearing hardware. Then, after reading the guidelines and criteria for the design project (± 5 minutes), he had 22 minutes to execute the design task on a drawing table allowing an upright posture. Once the task is completed, the subject had to take the NASA TLX Test, on the assessment of mental load (± 5 minutes) and a written post-experimental questionnaire on his impressions of the experiment (± 10 minutes). 2. After a break of 5-10 minutes, the participant answered a psychometric test, which is different for each session. These tests (± 20 minutes) are administered in the same order to each participant. Thus, in the first experimental session, the subject had to take the psychometric test from Ekstrom et al. (1978), on spatial performance (Factor-Referenced Cognitive Tests Kit). During the second session, the cognitive style is evaluated using Oltman's test (1971). Finally, in the third and final session, participant creativity is evaluated using Delis-Kaplan test (D-KEFS), Delis et al. (2001). Thus, this study will present the first results of quantitative measures to establish and validate the proposed model. Furthermore, the paper will also discuss the relevance of the proposed approach, considering that currently teaching of ideation in ours schools of architecture in North America is essentially done in a holistic manner through the architectural project.

source SIGraDi biobio2001 - [Proceedings of the 5th Iberoamerican Congress of Digital Graphics / ISBN 956-7813-12-4] Concepcion (Chile) 21-23 november 2001, pp. 67-70
summary This paper documents an initial study investigating the integration of Computational Fluid Dynamics (CFD) simulation modeling into wind mitigation design for building structures located in wind hazard prone areas. Some of the basic principles and theoretical concepts of fluid flow and wind pressure as well as their translation into design criteria for structural analysis and design are reviewed, followed by a discussion of a CFD application case study for a simulated hurricane force wind flow over a low rectangular building using the k-epsilon turbulence model. The techniques and parameters for development of the simulation are discussed and some preliminary interpretations of the results are evaluated by comparing its predictions against existing experimental and analytical data, with special attention paid to the American Society of Civil Engineers, Minimum Design Loads for Buildings and Other Structures, ACSE 7-98 and the Uniform Building Code .

title Exploiting Tools of Evaluation to Improve CAAD Teaching Methods. A Case Study of Inter & Intra ECTM Model
source Proceedings of the Ninth International Conference on Computer Aided Architectural Design Futures [ISBN 0-7923-7023-6] Eindhoven, 8-11 July 2001, pp. 215-230
summary This paper reports on an ongoing research study model into the Evaluation of CAAD Teaching Methods (ECTM) of which a number of resolutions and strategies were attained via an empirical investigation. The first stage of the study findings proposed a framework for the evaluation of architecture courses in tandem with CAAD. The second stage was based on the Inter & Intra ECTM design model as a strategy for acquiring solutions to CAAD problems through the exploitation of CAAD evaluation tools. The ECTM model structure criteria: the Model Concepts, the Operational Context, Dialectic Meanings, Relational Context, Performing Methods and Level of Integration were illuminated. ECTM model has a twofold involvement junctures, which describe CAAD evaluation behaviour. The first involves the evaluator in an interdepartmental comparison of CAAD integration into the curriculum, and/or between schools of architecture. The second engages the evaluator in an intradepartmental study of CAAD integration, and within the institution. The study projected an attempt to validate the Inter & Intra ECTM design model in concert with evaluation. The paper presents an extended description of the objectives, procedures and testing designed for the two abovementioned junctures composing the proposed ECTM case studies. Sequences of methods of data collection employed as a vehicle for the ECTM were Kirkpatrick model, questionnaire survey, observation (using an ECTM checklist) and experimental studies. The paper also explores variables and indicators used, and advances to shed some light on the methods of statistical analysis employment. ECTM model as a tool to attain CAAD effectiveness might redefine the role of collaborators/ team partnerships in CAAD tuition; and induce the level of technology selection and adaptation amongst schools, e.g. tutors and coursework interconnectivity. The ECTM model may also work as a framework of strategies to augment interactivity and positive learning amongst both staff and students.

summary Configurational studies are useful tools to architectural designing, since they help to understand the grouping of objects in the space (two-dimensional and/or threedimensional). The designer, after a classification of objects that satisfies the needs set to a group of objects, impose some restrictions to the objects that will govern the composition. These restrictions are those that will define the result through operations carried out by the designer. Among these operations the location of buildings in a determined area and the particular environmental qualities condition the final result. This work presents the results obtained by means of the implementation of a computing program of the type Evolution Program (EP) implemented in language C. The implementation of the program is explained in the first part of the paper. In the second part the successive steps are described. The numerical results obtained with the mentioned program are shown graphically. Examples of different complexity level illustrate the discussion of the theoretical matters.

summary The problem of heuristic biases (illusions) discussed by Tversky and Kahneman (1982) that can lead to errors in judgement by human designers, when they use precedent knowledge presented graphically (Bay 2001). A Cognitive framework of belief, goal, and decision, and a framework of representation of architectural knowledge by Tzonis are used to map out the problem of heuristic biases in the human mind. These are used to discuss what aspects of knowledge can be presented explicitly and digitally to users to make rebuttal more available for human thinking at the cognitive level. The discussion is applicable to both inductive and analytic digital knowledge systems that use precedent knowledge. This discussion is targeted directly at means of addressing bias in the human mind using digital means. The problem of human bias in machine learning and generalisation are discussed in a different paper, and the problems of international or non-intentional machine bias are not part of discussion in this paper.

title Cognitive Biases - The case of tropical architecture
source Delft University of Technology
summary This dissertation investigates, i) How cognitive biases (or illusions) may lead to errors in design thinking, ii) Why architects use architectural precedents as heuristics despite such possible errors, and iii) Develops a design tool that can overcome this type of errors through the introduction of a rebuttal mechanism. The mechanism controls biases and improves accuracy in architectural thinking. // The research method applied is interdisciplinary. It employs knowledge from cognitive science, environmental engineering, and architectural theory. The case study approach is also used. The investigation is made in the case of tropical architecture. The investigation of architectural biases draws from work by A. Tversky and D. Kahneman in 1982 on “Heuristics and biases”. According to Tversky and Kahneman, the use of heuristics of representativeness (based on similarity) and availability (based on ease of recall and imaginability) for judgement of probability can result in cognitive biases of illusions of validity and biases due to imaginability respectively. This theory can be used analogically to understand how errors arise in the judgement of environmental behaviour anticipated from various spatial configurations, leading to designs with dysfunctional performances when built. Incomplete information, limited time, and human mental resources make design thinking in practice difficult and impossible to solve. It is not possible to analyse all possible alternative solutions, multiple contingencies, and multiple conflicting demands, as doing so will lead to combinatorial explosion. One of the ways to cope with the difficult design problem is to use precedents as heuristic devices, as shortcuts in design thinking, and at the risk of errors. This is done with analogical, pre-parametric, and qualitative means of thinking, without quantitative calculations. Heuristics can be efficient and reasonably effective, but may not always be good enough or even correct, because they can have associated cognitive biases that lead to errors. Several debiasing strategies are discussed, and one possibility is to introduce a rebuttal mechanism to refocus the designer’s thinking on the negative and opposite outcomes in his judgements, in order to debias these illusions. The research is carried out within the framework of design theory developed by the Design Knowledge System Research Centre, TUDelft. This strategy is tested with an experiment. The results show that the introduction of a rebuttal mechanism can debias and improve design judgements substantially in environmental control. The tool developed has possible applications in design practice and education, and in particular, in the designing of sustainable environments.

summary The theme of this conference builds on and investigates the pre-existing and endlessly unfolding relationship between two domains of scientific inquiry: Architecture, urban design and planning, environmental design, geography and Social theory, media and communication studies, political science, cultural studies and social anthropology. Architectural design involves communication and could thus be partly considered a communicational activity. Designers (or not) see architectural designs, implicitly, as carriers of information and symbolic content; similarly buildings and urban environments have been “read” and interpreted by many (usu- ally not architects) as cultural texts. At the same time, social and cultural studies have studied buildings and cities, as contexts for social and cultural activities and life in general, from their mundane expression of “everyday life” (Highmore, 2001) to elite expressions of artistic creativity and performance. Information and communication technologies (ICTs) support both of these levels of scientific inquiry in many ways. Most importantly however, ICTs need design studies, architectural and visual design, social and cultural studies in their quest to create aesthetically pleasing, ergonomically efficient and functional ICT sys- tems; this need for interdisciplinarity is best articulated by the low quality of most on-line content and applica- tions published on the web.

summary A new generative design system based on a genetic algorithm is tested within the framework of Alvaro Sizaís School of Architecture at Oporto, Portugal. The system works over a detailed three-dimensional description of the building and uses natural lighting and overall environmental performance as objective functions to guide the generation of solutions. This paper researches the encoding of architectural design intentions into the system, using constraints derived from Sizaís original design. Experiments using this generative system were performed on three different geographical locations to test the algorithmís capability to adapt solutions to different climatic characteristics within the same language constraints.

title Evaluating Office Buildings with MOLCA(Model for Office Life Cycle Assessment)

summary MOLCA (Model for Office Life Cycle Assessment) is a project that aims to develop a tool that enables designers and builders to evaluate the environmental impact of their designs (of office buildings) from a environmental point of view. The model used is based on guidelinesgiven by ISO 14000, using the so-called Life Cycle Assessment (LCA) method. The MOLCA project started in 1997 and will be finished in 2001 resulting in the aforementioned tool. MOLCA is a module within broader research conducted at the Eindhoven University of Technology aiming to reduce design risks to a minimum in the early design stages.Since the MOLCA project started two major case-studies have been carried out. One into the difference in environmental load caused by using concrete and steel roof systems respectively and the role of recycling. The second study focused on biases in LCA data and how to handle them. For the simulations a computer-model named SimaPro was used, using the world-wide accepted method developed by CML (Centre for the Environment, Leiden, the Netherlands). With this model different life-cycle scenarios were studied and evaluated. Based on those two case studies and a third one into an office area, a first model has been developed.Bottle-neck in this field of study is estimating average recycling and re-use percentages of the total flow of material waste in the building sector and collecting reliable process data. Another problem within LCA studies is estimating the reliability of the input data and modelling uncertainties. All these topics will be subject of further analysis.

title Simulation and representation. Learning from airflow analyses in buildings
source Proceedings of the Ninth International Conference on Computer Aided Architectural Design Futures [ISBN 0-7923-7023-6] Eindhoven, 8-11 July 2001, pp. 657-666
summary The simulation of environmental aspects is a current priority in design research and practice. The availability of relatively efficient and reliable simulation systems and the emphasis on environmental aspects throughout a building’s lifecycle combine to stimulate exploration of aspects such as lighting and air quality by computational means. Nevertheless, a frequent complaint is that the addition of such simulations makes design information processing timeconsuming and cumbersome, thereby increasing uncertainty and indecision. Therefore, it is imperative that simulation is integrated in the strategies and tools normally used by the digitally-minded architect. In this respect a central issue is the relations between the simulation and the design representation used as connecting tissue for the whole design environment. Input of design information in the simulation means identification of relevant objects, aspects, parts and properties of these objects, as well as relationships between objects. The explicit description of objects such as spaces, doors and windows in the design representation allows for ready extraction of relevant information, including automatic recognition of relationships such as adjacency between a window and a space. The addition of information specific to the airflow analysis was resolved by the extension of the representation to cover front-end service components such as inlets and outlets and general properties (annotations) such as activities accommodated in a space and the primary choice of cooling and heating subsystems. The design representation is also the obvious target for the output of the simulation (feedback). Visualization of airflow in terms of the resulting voxels makes effortless and enjoyable viewing but merely allowing the visualization to coexist with the representation of spaces and building elements does not provide design guidance. One way of achieving that is by treating spaces not as integral entities but as containers of relevant surfaces. These surfaces determine the adaptive subdivision of the space and function as attractors for voxel clustering.

summary Urban planners who need to design information systems require an understanding of systems analysis, data acquisition and GIS. Planners have moved beyond drawing land use plans, to examining the evolution of urban activities to monitor and analyze urban societal and environmental problems. Novel tools, like using multimedia information systems and GIS, will become an increasingly important, eventually essential part of the job. Both practitioners and students will find this book useful, provided they have an adequate grounding in computing, data analysis and GIS and they are looking to use and design computer systems for developing maps and written statements for city planning.

title MAQUETE VIRTUAL APLICADA EM DIAGNÓSTICO DE ADEQUAÇÃO: EDIFÍCIO CORPORATIVO DO INPI / RJ - BRASIL (Virtual Model Applied to Adequacy Diagonosis: INPI Corporate Building (Rio de Janeiro - Brasil))
source SIGraDi biobio2001 - [Proceedings of the 5th Iberoamerican Congress of Digital Graphics / ISBN 956-7813-12-4] Concepcion (Chile) 21-23 november 2001, pp. 291-294
summary This paper presents a case study were computer aided graphic modelling was applied for environmental diagnostics of the INPI building at Rio de Janeiro. The research improved a walk-thought analysis in order to identify user conditions (ergonomics, layout, maintenance, security, etc.). Using CAD / PC, we developed a virtual model of the building and its workspaces, and both the results of diagnosis applied forms, updated plants and photos were organised in the virtual model, linked to a database containing tables with elements of the case study. This database is intended to support decisions in organisational planning, by query (SQL routines) on virtual model (CAD), providing graphically visualised answers and extracts of data search results.

title Towards a framework for evaluation of computer visual simulations in environmental design
source Design Studies 22 (2) (2001) pp. 193-209
summary Research has been conducted into the assessment of visual simulation as a credible method for predicting future environments, especially in building and landscape evaluation. Despite this work a conceptual framework to guide research and practice in this field has not been developed. The recent and increasingly widespread use of computer simulation in design has created an urgent need to develop a conceptual framework which can test prevailing assumptions and provide the basis for the development of an accepted theory in the field. This paper proposes such a framework, and identifies and relates the significant variables, which impact upon the application of visual simulation in an environmental design, task-orientated context.

title Architectural Design Development through Multimedia Interaction
source Proceedings of the Ninth International Conference on Computer Aided Architectural Design Futures [ISBN 0-7923-7023-6] Eindhoven, 8-11 July 2001, pp. 299-314
summary This paper describes the development of a multimedia system aimed at architects and architectural students for the purpose of helping them to understand the basic concepts of architectural analysis. Analytical features in the system that we have developed include many design-theoretic concepts such as massing, balance and circulation. Other concepts are more directly related to the built environment and include elements such as lighting, structure and construction. The system illustrates architectural analysis carried out on a range of building types dynamically, and allows users to navigate architectural analyses interactively. Users can learn about the differences between buildings and their corresponding analyses in a supportive non-linear learning process, and can explore building types depending upon their own interests or needs. The prototype system contains analyses of three British building projects. They show different types of architecture in order to demonstrate important design theoretic and environmental differences. Conceptual models in the system show important aspects of a particular analysis simply, and each analysis is additionally described with text, animations, video clips and interviews with architects (talking heads). Most of the models were generated by the use of architectural CAD software. Animation techniques were used to describe the analyses of buildings clearly and dynamically. Users can visualise how whole buildings were designed from an analytical point of view, and the system illustrates design thinking by showing dynamic presentations of analyses. Users can structure their own design learning processes through a series of interactions. These interactions are supported with flexible cross-referencing mechanisms implemented in Macromedia Director 8.0 exploiting Frame Markers, Event Handling, Navigation, and Buttons in the context of the object-oriented Lingo programming language. The navigation component of this system has a logical matrix structure reflecting the fact that analytical information is interrelated across building types, giving rise to vertical and horizontal patterns of access. The features of Director 8.0 can control this navigation in a flexible yet structured way. Users not only learn about analysis, but also how to present their own designs to the public through the use of different kinds of presentation techniques, particularly through the use of conceptual models. We intend that users can show their projects from their own analytical viewpoints instead of simply showing realistic images of final designs. Presentations can also be recorded in the system, and these can in turn be used as reference material for other users. This system is currently being developed further by storing presentations and translating them into different languages (e.g. Japanese) so that foreign users in other institutions can interact with these presentations. This system has been evaluated in the context of an undergraduate CAD course at the School of Architecture, University of Sheffield, UK. We are currently examining the usefulness of the system based upon an evaluation process, in addition to including more building types for future study.
