title	A survey of computer software for the urban designprocess
source	H.J.P. Timmermans, B. de Vries (eds.) 2008, Design & Decision Support Systems in Architecture and Urban Planning, ISBN 978-90-6814-173-3, University of Technology Eindhoven, published on CD
summary	Urban design is concerned with the shape, the surface and the physical arrangement of all kinds of urban elements, the basic components that make up the built environment, at the level of buildings, spaces and human activities. It is also concerned with the non-visual aspects of the environment, such as noise, wind and temperature and humidity. The city square is a particular urban element which can take many forms and its geometrical relationships such as maximum dimensions, ratio of width to length and building height to length have been analysed for centuries (Alberti 1475), (Vitruvius 1550), (Sitte 1889), (Corbett 2004). Within the current urban design process there are increasing examples of three dimensional computer representations which allow the user to experience a visual sense of the geometry of city squares in an urban landscape. Computer-aided design and Virtual Reality technologies have recently contributed to this visual assessment, but there have been limited attempts at 3D computer representations which allow the user to experience a greater sense of the urban space. This paper will describe a survey of computer tools which could support a more holistic approach to urban design and which could be used to simulate a number of urban texture and urban quality aspects. It will provide a systematic overview of currently available software that could support the simulation of building density, height, colour and style as well as conditions relating to noise, shading, heat, natural and artificial light. It will describe a methodology for the selection and filtering of appropriate computer applications and offer an initial evaluation of these tools for the analysis and representation of the three-dimensional geometry, urban texture and urban quality of city centre spaces. The paper is structured to include an introduction to the design criteria relating to city centre spaces which underpins this research. Next the systematic review of computer software will be described, and selected tools will undergo initial evaluation. Finally conclusions will be drawn and areas for future research identified.

title	Sketch-based Methods for Researching Building Layouts through the Semantic Fingerprint of Architecture
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. 85-102.
summary	The paper focuses on the early stages of the design process where the architect needs assistance in finding reference projects and describes different aspects of a concept for retrieving previous design solutions with similar layout characteristics. Such references are typically used to see how others have solved a similar architectural problem or simply for inspiration. Current electronic search methods use textual information rather than graphical information. The configuration of space and the relations between rooms are hard to represent using keywords, in fact transforming these spatial configurations into verbally expressed typologies tends to result in unclear and often imprecise descriptions of architecture. Nowadays, modern IT-technologies lead to fundamental changes during the process of designing buildings. Digital representations of architecture require suitable approaches to the storage, indexing and management of information as well as adequate retrieval methods. Traditionally planning information is represented in the form of floor plans, elevations, sections and textual descriptions. State of the art digital representations include renderings, computer aided design (CAD) and semantic information like Building Information Modelling (BIM) including 2D and 3D file formats such as Industry Foundation Classes (IFC) (IAI, 2010). In the paper, we examine the development of IT-technologies in the area of case-based reasoning (Richter et al., 2007) to provide a sketch-based submission and retrieval system for publishing and researching building layouts including their manipulation and subsequent use. The user interface focuses on specifying space and their relations by drawing them. This query style supports the spatial thinking approach that architects use, who often have a visual representation in mind without being able to provide an accurate description of the spatial configuration. The semantic fingerprint proposed by (Langenhan, 2008) is a description and query language for creating an index of floor plans to store meta-data about architecture, which can be used as signature for retrieving reference projects. The functional spaces, such as living room or kitchen and the relation among on another, are used to create a fingerprint. Furthermore, we propose a visual sketch-based interface (Weber et al., 2010) based on the Touch&Write paradigm (Liwicki et al., 2010) for the submission and the retrieval phase. During the submission process the architect is sketching the space-boundaries, space relations and functional coherence's. Using state of the art document analysis techniques, the architects are supported offering an automatic detection of room boundaries and their physical relations. During the retrieval the application will interpret the sketches of the architect and find reference projects based on a similarity based search utilizing the semantic fingerprint. By recommending reference projects, architects will be able to reuse collective experience which match the current requirements. The way of performing a search using a sketch as a query is a new way of thinking and working. The retrieval of 3D models based on a sketched shape are already realized in several domains. We already propose a step further, using the semantics of a spatial configuration. Observing the design process of buildings reveals that the initial design phase serves as the foundation for the quality of the later outcome. The sketch-based approach to access valuable information using the semantic fingerprint enables the user to digitally capture knowledge about architecture, to recover and reuse it in common-sense. Furthermore, automatically analysed fingerprints can put forward both commonly used as well as best practice projects. It will be possible to rate architecture according to the fingerprint of a building.

title	Global Visualisation Engines – Issues for Urban Landscape Planning Participation Processes
source	Digital Design in Landscape Architecture 2008, Proceedings at Anhalt University of Applied Sciences, 29-31 May 2008
summary	Traditional planning processes use two-dimensional drawings, plans, sections, elevations and artists’ impressions to communicate design intent to interested parties. Three-dimensional computer visualisation technologies that support the planning process raise institutional and organisational challenges as their perceived benefits are considered. Virtual Reality (VR) models add interactivity and immersiveness to landscape visualisations but require appropriate technical input and management. This paper explores two main themes. Firstly, how interactive 3D computer simulations of planning proposals can be adopted to successfully improve the traditional process. It reports on a pilot study to examine how architects, clients, planning officers and university researchers have worked together to systematically examine and analyse this changing process. It reports on issues concerned with ownership of city models, the roles and the compatibility, accuracy and remote sharing of urban data. Secondly, we explore the emerging theme of web-based GIS applications and their impact on architectural visualisation. The process of placing urban data onto Google Earth was tested and the resulting issues emerging with this software, including IT and data management and accuracy issues for suitable architectural visualisation are discussed. The study also reports and offers an overview of placing accurate urban landscape data onto Google Earth and a discussion of using this method for online public participation and communicating technical building information.

title	Integrated Design and Building System for the Provision of Customized Housing: the Case of Post-Earthquake Haiti
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. 247-264.
summary	The paper proposes integrated design and building systems for the provision of sustainable customized housing. It advances previous work by applying a methodology to generate these systems from vernacular precedents. The methodology is based on the use of shape grammars to derive and encode a contemporary system from the precedents. The combined set of rules can be applied to generate housing solutions tailored to specific user and site contexts. The provision of housing to shelter the population affected by the 2010 Haiti earthquake illustrates the application of the methodology. A computer implementation is currently under development in C# using the BIM platform provided by Revit. The world experiences a sharp increase in population and a strong urbanization process. These phenomena call for the development of effective means to solve the resulting housing deficit. The response of the informal sector to the problem, which relies mainly on handcrafted processes, has resulted in an increase of urban slums in many of the big cities, which lack sanitary and spatial conditions. The formal sector has produced monotonous environments based on the idea of mass production that one size fits all, which fails to meet individual and cultural needs. We propose an alternative approach in which mass customization is used to produce planed environments that possess qualities found in historical settlements. Mass customization, a new paradigm emerging due to the technological developments of the last decades, combines the economy of scale of mass production and the aesthetics and functional qualities of customization. Mass customization of housing is defined as the provision of houses that respond to the context in which they are built. The conceptual model for the mass customization of housing used departs from the idea of a housing type, which is the combined result of three systems (Habraken, 1988) -- spatial, building system, and stylistic -- and it includes a design system, a production system, and a computer system (Duarte, 2001). In previous work, this conceptual model was tested by developing a computer system for existing design and building systems (Benr__s and Duarte, 2009). The current work advances it by developing new and original design, building, and computer systems for a particular context. The urgent need to build fast in the aftermath of catastrophes quite often overrides any cultural concerns. As a result, the shelters provided in such circumstances are indistinct and impersonal. However, taking individual and cultural aspects into account might lead to a better identification of the population with their new environment, thereby minimizing the rupture caused in their lives. As the methodology to develop new housing systems is based on the idea of architectural precedents, choosing existing vernacular housing as a precedent permits the incorporation of cultural aspects and facilitates an identification of people with the new housing. In the Haiti case study, we chose as a precedent a housetype called ‚Äúgingerbread houses‚Äù, which includes a wide range of houses from wealthy to very humble ones. Although the proposed design system was inspired by these houses, it was decided to adopt a contemporary take. The methodology to devise the new type was based on two ideas: precedents and transformations in design. In architecture, the use of precedents provides designers with typical solutions for particular problems and it constitutes a departing point for a new design. In our case, the precedent is an existing housetype. It has been shown (Duarte, 2001) that a particular housetype can be encoded by a shape grammar (Stiny, 1980) forming a design system. Studies in shape grammars have shown that the evolution of one style into another can be described as the transformation of one shape grammar into another (Knight, 1994). The used methodology departs takes off from these ideas and it comprises the following steps (Duarte, 2008): (1) Selection of precedents, (2) Derivation of an archetype; (3) Listing of rules; (4) Derivation of designs; (5) Cataloguing of solutions; (6) Derivation of tailored solution.

title	Improved Understanding of Urban Sprawl Using Neural Networks
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: 14020-2408-8, p. 33-49
summary	It is widely accepted that the spatial pattern of settlements is a crucial factor affecting quality of life and environmental sustainability, but few recent studies have attempted to examine the phenomenon of sprawl by modelling the process rather than adopting a descriptive approach. The issue was partly addressed by models of land use and transportation which were mainly developed in the UK and US in the 1970s and 1980s, but the major advances were made in the area of modelling transportation, while very little was achieved in the area of spatial and temporal land use. Models of land use and transportation are well-established tools, based on explicit, exogenouslyformulated rules within a theoretical framework. The new approaches of artificial intelligence, and in particular, systems involving parallel processing, (Neural Networks, Cellular Automata and Multi-Agent Systems) defined by the expression “Neurocomputing”, allow problems to be approached in the reverse, bottom-up, direction by discovering rules, relationships and scenarios from a database. In this article we examine the hypothesis that territorial micro-transformations occur according to a local logic, i.e. according to use, accessibility, the presence of services and conditions of centrality, periphericity or isolation of each territorial “cell” relative to its surroundings. The prediction capabilities of different architectures of supervised Neural networks are implemented to the south Metropolitan area of Milan at two different temporal thresholds and discussed. Starting from data on land use in 1980 and 1994 and by subdividing the area into square cells on an orthogonal grid, the model produces a spatial and functional map of urbanisation in 2008. An implementation of the SOM (Self Organizing Map) processing to the Data Base allows the typologies of transformation to be identified, i.e. the classes of area which are transformed in the same way and which give rise to territorial morphologies; this is an interesting by-product of the approach.

title	Constraint-Based Design in Participatory Housing Planning
source	International Journal of Architectural Computing vol. 6 - no. 1, pp. 97-117
summary	We introduce some novel ideas for a constraint-based design strategy to support participatory housing planning processes in Latin America. The following lines intend to open the discussion on the requirements and effect of the computer implementation of a constraint satisfaction approach to solve elementary design problems in architectural practice. The case study applies to the building massing design problem posed by the Chilean urban regulatory framework that addresses single-family affordable houses. Two different implementation criteria are being tested in an ongoing series of trials providing further considerations. One prototype uses MAXON's CINEMA4D XPRESSO® visual scripting environment to set up a semi-automated design environment which allows users to edit one feature-based 3D model of massing alternative at a time. The other prototype uses ILOG's OPL STUDIO® constraint programming environment to achieve fully automated search and 2D visualization of all possible solution alternatives to separate subdomains of the building massing design problem.

title	Analyzing Pedestrian Movement in Mataf Using GPSand GIS to Support Space Redesign
source	H.J.P. Timmermans, B. de Vries (eds.) 2008, Design & Decision Support Systems in Architecture and Urban Planning, ISBN 978-90-6814-173-3, University of Technology Eindhoven, published on CD
summary	Evaluating the use of architectural and urban spaces is an important issue for architects and urban designers who wish to enhance space usability. Space usability is crucial in crowded spaces such as Mataf areas. Millions of people come to the city of Makkah, Saudi Arabia every year to perform Hajj (Islamic Pilgrimage) and Umrah. A cornerstone of Hajj and Umrah spirituals is to perform Tawaf, which is the circumambulation of the Ka'bah in the center of the Holy Mosque in Makkah. The areas of performing Tawaf (called Mataf) become very crowded during Hajj and the last ten days of Ramadan. This paper demonstrates how we utilized Global Positioning Systems (GPS) and Geographic Information Systems (GIS) to analyze pedestrian movement while performing Tawaf. During the Hajj of 1424 H (2004 in the Georgian Calendar), several GPS devices were used to collect pedestrian movement coordinates at specific time intervals. Computer software for tracking analysis is used to visualize and analyze the pattern of pedestrian movement in Tawaf. The software allows users to view temporal data, which can be set up with past time windows for historical data analysis. The findings of this research show levels of service and flow rates throughout different zones and times of Mataf. They indicate the most critical zones and times for Tawaf during Hajj. They also visually demonstrate the track pattern of pedestrian movement at different locations in the Tawaf area. The paper concludes with some redesign recommendations to remove obstacles and facilitate pedestrian movement in Tawaf. The approach described in this paper can be implemented in architectural and urban design space modifications to improve pedestrian movement in open spaces.

source	Architecture in Computro [26th eCAADe Conference Proceedings / ISBN 978-0-9541183-7-2] Antwerpen (Belgium) 17-20 September 2008, pp. 693-700
summary	This paper documents a research pilot study; it is a comparative investigation between an expert designer and a novice designer. The study used protocol analysis to examine design cognitive actions whilst using 3D digital media during the conceptual stage of design. The empirical study found novice designers capable of managing a design process of complex objects due to the increase in their contribution of design strategies to the overall process. The possible reason for this may be due to using free-form modelling with accuracy aids found in computing facilities. This provides evidence to suggest automated computing should be encouraged within the pedagogical framework of architectural design.

summary	This paper outlines the digital design processes involved in the design and construction of the new Elephant House at Copenhagen Zoo. Early design concepts for the canopy were tested using physical sketch models. The geometric complexity of these early physical models led to the involvement of the Specialist Modelling Group and the use of the computer to digitally sketch 3D CAD models. After many studies, the complex form of the canopies was rationalised using torus geometry. A computer program was written to generate the canopy glazing and structure. This parametric system was developed to be a design tool, and was developed by an architectural designer working with the team. Through its use the team were able to explore more design options, and alter the design farther along in the design process; however, this generative tool was created largely as a CAD efficiency tool. Another series of computer programs were written to generate and populate a shading system based on environmental analysis. Unlike the computer program that generated the structure and glazing, this program was not developed to make the generation of complex geometric structures more efficient, but developed to explore computational approaches that would have been impossible without the computer. Most of the canopy’s design was communicated to fabricator through a geometry method statement, a method that has been proven to be effective in the past. The project completed in June 2008.

summary	Historically, the city represents not just a collection of buildings, but also the concrete cosmology of the world. The importance of geometry in this context is that one can be assured that one’s understanding of the form of the city will correspond to meaning. It is this reading that is the canonical visualization method of the city form. But contemporary urban designers are confronted by cities with overlapping systems of movement and information that has made the reading of geometry insufficient for an understanding of the city. Our interdisciplinary team of researchers has been studying issues related to urban visualization from the perspectives of urban design and computer visualization. Together, we have published work demonstrating how very large and disparate data sets can be visualized and integrated in unique ways. Building on this existing work that connects the two disciplines, this paper presents a survey of six urban design methodologies that may be useful for visualization. Each approach is described through a brief history, a conceptual overview and a diagrammatic exegesis. The conclusion presents an overview of the complementary natures of the discourses in urban design and computer visualization and a prospectus for application of the identified methodologies to computer urban visualization. We conclude that urban theories can inform urban visualization both as a method of informing generation and run-time simplification of 3D geometric modeling and in managing information visualization overlay issues for the very large, over-lapping data sets.

summary	AUTOMATED COST ANALYSIS OF CONCEPT DESIGN BIM MODELS Interoperability: BIM models and cost models This paper introduces the automated cost analysis developed for the General Services Administration (GSA) and the analysis results of a case study involving a concept design courthouse BIM model. The purpose of this study is to investigate interoperability issues related to integrating design and analysis tools; specifically BIM models and cost models. Previous efforts to generate cost estimates from BIM models have focused on developing two necessary but disjoint processes: 1) extracting accurate quantity take off data from BIM models, and 2) manipulating cost analysis results to provide informative feedback. Some recent efforts involve developing detailed definitions, enhanced IFC-based formats and in-house standards for assemblies that encompass building models (e.g. US Corps of Engineers). Some commercial applications enhance the level of detail associated to BIM objects with assembly descriptions to produce lightweight BIM models that can be used by different applications for various purposes (e.g. Autodesk for design review, Navisworks for scheduling, Innovaya for visual estimating, etc.). This study suggests the integration of design and analysis tools by means of managing all building data in one shared repository accessible to multiple domains in the AEC industry (Eastman, 1999; Eastman et al., 2008; authors, 2010). Our approach aims at providing an integrated platform that incorporates a quantity take off extraction method from IFC models, a cost analysis model, and a comprehensive cost reporting scheme, using the Solibri Model Checker (SMC) development environment. Approach As part of the effort to improve the performance of federal buildings, GSA evaluates concept design alternatives based on their compliance with specific requirements, including cost analysis. Two basic challenges emerge in the process of automating cost analysis for BIM models: 1) At this early concept design stage, only minimal information is available to produce a reliable analysis, such as space names and areas, and building gross area, 2) design alternatives share a lot of programmatic requirements such as location, functional spaces and other data. It is thus crucial to integrate other factors that contribute to substantial cost differences such as perimeter, and exterior wall and roof areas. These are extracted from BIM models using IFC data and input through XML into the Parametric Cost Engineering System (PACES, 2010) software to generate cost analysis reports. PACES uses this limited dataset at a conceptual stage and RSMeans (2010) data to infer cost assemblies at different levels of detail. Functionalities Cost model import module The cost model import module has three main functionalities: generating the input dataset necessary for the cost model, performing a semantic mapping between building type specific names and name aggregation structures in PACES known as functional space areas (FSAs), and managing cost data external to the BIM model, such as location and construction duration. The module computes building data such as footprint, gross area, perimeter, external wall and roof area and building space areas. This data is generated through SMC in the form of an XML file and imported into PACES. Reporting module The reporting module uses the cost report generated by PACES to develop a comprehensive report in the form of an excel spreadsheet. This report consists of a systems-elemental estimate that shows the main systems of the building in terms of UniFormat categories, escalation, markups, overhead and conditions, a UniFormat Level III report, and a cost breakdown that provides a summary of material, equipment, labor and total costs. Building parameters are integrated in the report to provide insight on the variations among design alternatives.

title	From physical models to immersive collaborative environments: testing the best way for homeless people to visualise and negotiate spaces
source	SIGraDi 2008 - [Proceedings of the 12th Iberoamerican Congress of Digital Graphics] La Habana - Cuba 1-5 December 2008
summary	This paper describes an experiment to investigate the best way for lay people to use representation to visualise and negotiate space. It was motivated by our observations in workshops for digital inclusion in the context of a housing project for a homeless association. Computers were used to make it easier for the community to understand and change the spaces in real time. The first workshops proved that our approach was efficient as an exercise but not certainly effective concerning the understanding of spatial qualities. So we have designed an experiment to compare the usability of different media in participatory design processes. For that we have adapted the ‘Usability’ methodology, which is fully described in the paper. We started with three main questions. The first concerned the effectiveness of different media to represent spatial quality; the second concerned the best way for novices to approach space, whether by refurbishing a pre-existing space or by starting from the scratch; and the third concerned the effectiveness of negotiation by means of discourse and by means of or action. We also had two main hypothesis: one coming from research on digital environments and stereo visualisation, indicating that the more people feel immersed in the represented environment the more they are able to correlate it with physical space; and the other coming from our own observations in the participatory design workshops, in which the collective decision-making was manipulated by those people with more advanced communication skills who use their ability in an authoritative way regardless of the relevance of what they have to say. This paper describes the whole experiment, which was an exercise of spatial negotiation in 5 versions. In the first version we provided fixed digital views of a room in plan and axonometry; for another two versions we provided a physical model of the room in 1:10 scale, with some pieces of the existing furniture in different scales. This was done to check if people were just playing with a puzzle or actually grasping the correspondence between representation and the object or the space represented. One version proposes refurbishment and the other starts from the scratch. And the last two versions repeated the same task made with the physical model, but this time using a 3D interactive digital model. People were required not only to organise the furniture in the space but also to build a full scale cardboard structure and organise the real furniture reproducing their proposed model. Their comments on the spaces they had built confronted with what they had imaged when working with the model has enabled us to compare the different models, as also the different ways of negotiating spaces. This paper describes this experiment in detail concluding that 3D digital interactive models are far more effective than physical models and 2D drawings; when negotiation happens by means of action it provides more creative results than when the discoursive practice prevails; people are more creative when they start something from scratch, though they spend more time. The results of this experiment led us to formulate a new hypothesis leading to the development of an immersive collaborative environment using stereoscopy.

title	Analytical Study of the Projects of Students in the Architectural Design - Comparision Between Physical and Digital Models
source	Proceedings of the 8th European Architectural Endoscopy Association Conference
summary	Since its foundation in 1981, Architectural faculty has adopted traditional teaching methods for practical subjects such as architectural design and Urban planning. In these subjects, students submitted their projects and exams on (chanson) and (calk) sheets using various drawing tools. Such tools are still in use by students up to date in manually architectural concept presentation. This comes after the students pass a number of subjects related to art and engineering drawing that help the students in gaining drawing representation and rendering skills.

title	Towards client-focused architectural representationsas a facilitator for improved design decision-makingprocess
source	H.J.P. Timmermans, B. de Vries (eds.) 2008, Design & Decision Support Systems in Architecture and Urban Planning, ISBN 978-90-6814-173-3, University of Technology Eindhoven, published on CD
summary	This paper focuses on architectural representations as a means of communicating design schemes in the process of decision-making. It reports on the study, which investigated people’s responses to different forms of architectural representations. The paper starts with the discussion about participation in decision-making process and the potential benefits of using computer generated representations. Then, it describes the research study and examines results of the investigation. In the final section it is argued that client focused architectural representations are needed to support the exchange of views and discussion amongst different stakeholders in order to reduce the requirement for trained interpretation and encourage the participation in the decision making process.

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

title	Urban micro-informatics: a test case for high-resolution urban modelling through aggregating public information sources

summary	Our contention is that the city is a rich collection of urban micro-ecologies in continuous formation that include information types outside the traditional boundaries of urban design, city planning, and architecture and their native data fields. This paper discusses working with non-standard urban data types of a highly granular nature, and the analytical possibilities and technical issues associated with their aggregation, through a post professional masters level research studio project run in 2008. Opportunities for novel urban analysis arising from this process are discussed in the context of typical urban planning and analysis systems and locative media practices. This research bought to light specific technical and conceptual issues arising from the combination of processes including sources of data, data collection methods, data formatting, aggregating and visualisation. The range and nature of publicly available information and its value in an urban analysis context is also explored, linking collective information sites such as Pachube, to local environmental analysis and sensor webs. These are discussed in this paper, toward determining the possibilities for novel understandings of the city from a user centric, real-time urban perspective.

summary	While conventional information displays are still effective, a lack of integration between descriptive and contextual information means they cannot be used independently of additional external information. New digital systems such as Google Maps are increasing in popularity. Unfortunately these present some limitations in terms of understanding both route and survey information, and in particular navigation and orientation, such as intuitively understanding a plan view no matter which way one is facing, so visitors can quickly and intuitively learn how to get to specific buildings or to specific facilities. Digital systems may also alienate older and non computer literate users; and they display contextual information inside an interface which limits the possible range of interaction methods offered by physical interaction. Our solution was to create a 3D physical model that one could spin, which would in turn display digital panoramas that spun in rotational alignment with the physical city model. Further, the user could place category tokens in intersections of the city model, which would bring up digital panoramas on the screen and highlight facilities linked to the category chosen. Rotating the token would also rotate the digital panorama.

title	Interactive parametric modelling: POG a tool the cultural heritage monument 3D reconstruction
doi	https://doi.org/10.52842/conf.caadria.2008.487

summary	Historic monument and archaeological site 3D reconstruction is nowadays often required for many applications (scientific and architectural studies, virtual visits for a better understanding of the monument, etc). This task is very time-consuming. Automating the modelling of the most common components could ease this 3D work and produce accurate, consistent and re-usable models. Based upon compound rules of architectural elements but also upon various other data sources such as photographs and 3D laser scans, we have conceived and developed an interactive tool for virtual 3D reconstruction of heritage monuments. It allows a quick modelling and accurate adjustments to the measured data. This tool could be a great help for architects and archaeologists. Research first has began with the study of classical architecture, and has gone on with other architectural styles. Architectural elements are described with parametric data, then generated by our tool. Our main application context was the town of Nancy in France where there are lots of classical architecture buildings which allow us to test our tool. It will be further extended to be applied to other architectural styles and will be combined with photogrammetry methods.

title	What is the state of digital architectural design?
source	SIGraDi 2008 - [Proceedings of the 12th Iberoamerican Congress of Digital Graphics] La Habana - Cuba 1-5 December 2008
summary	What is the state of digital architectural design? The ubiquity of the computer in architecture can be seen in the many computer based presentations from famous architectural practices. BIM (Building Information Modelling) is the key word and we can see implementations in very ambitious projects all over the world. Glossy magazines show the results of this kind of architecture and predict that this is the future of our profession. But when we go out into the “small world” (in Europe) and talk with architects in small firms, there is a very different reality – at least at the moment. Although they all agree that the computer is crucial for their work, it is a love/hate relationship for many them. Most still use the computer purely as a drafting device and AutoCAD is still the dominant tool. Although many of them agree with the statement that you can use the computer for design, only a minority really use the computer as a design tool in the early design stages. To find out more about the reality of the use of computers in design in “small town Europe” we have been undertaking two different kinds of research over the past 4 years. The first one is an educational experiment using first year’s students to find out about the different qualities of designing with and without the computer. The results have been presented at previous conferences and, since we are doing a last run of these experiments this year, we will update and finalise our findings in this paper. To make it comparable to previous years, we use largely the same settings using the same type of student (first year) and the same project/site. We will also be comparing the results for students designing ‘freestyle’ ie in the way that they want against the previous years controlled groups. The second strand of research we have followed is a survey amongst practitioners and some of the above statements came out of this survey. We did this survey using a web questionnaire and focused on a particular region of Europe. Although the numbers of participants for this survey were quite satisfying we are re-running the survey in a different region and country to see whether there are significant differences. The results of our research and our experience as teachers and architects leads us to the main question of how we can give recommendations on how to teach design the new generation of architects. In many aspects most of the teaching that is done in our faculties is still strictly divided into teaching design and teaching computer skills. The crucial question for architectural education are the implications of the ubiquity of the computer will have especially in the field of design. We will try to give some suggestions for these effects this could have on our teaching. In the long run, this is the only way to avoid some of the pitfalls and bring the benefits of computers in design to our small architectural firms. The paper will present a summary of the results of our research and try to propose an answer to the question: “What is the state of digital design in small town Europe?”
