title	Spatial Visualization of abstract Information: A Classification Model for Visual Spatial Design Guidelines in the Digital Domain
source	Swiss Federal Institute of Technology, ETH Zurich
summary	Visualization of abstract information refers to the design of graphical representations of information that has no simple relation to known concrete or physical forms. Designing visualizations of abstract information requires proposing visual representation for often a large body of data pants. determining a meaningful structure for the complex relations among them and suggesting a method for Interacting with this body of data. Spatial perception plays an Important role for cognitive processing when interacting with abstract information, slice spatially-organized Information can be accessed and operated on rapidly and effortlessly, especially when a spatial arrangement reveals the conceptual organization of Information. This thesis focuses on aspects of the spatial visual design of abstract information presented as computer-generated. dynamic and interactive images accessible through flat displays. The process of spatial visualization design is shaped by various factors including interactive, perceptual, navigational as well as organizational and metaphorical aspects and as such requires an interdisciplinary approach. Therefore, in researching spatial visual design. it is crucial to use methods facilitating the process of sharing competencies among different disciplines. In this thesis, we introduce a new classification model accommodating features important in designing effective spatial visualizations of abstract information. To enhance the effectiveness of spatial visualization, this model offers a holistic approach in classifiying spatial Visualization features. As part of the model, we analyze properties already used in architectural representation and other visual design disciplines for spatial presentations as well as investigate their potential usage in digital domains of abstract information. The process of spatial visualization In the digital environment is mostly based on the practical experience of a designer. and therefore the majority of spatial design know-how is heuristic in nature. Based on this assumption, we present a set of guidelines addressing the general problem of spatial design. The Spalial Design Classificahon Model, Visual Spatial Properties and Spatial Design Guidelines build an extendable infrastructure which becomes a first step towards augmenting the quality of spatial information design- We propose to use this infrastructure as a general blueprint for structuring the exchange of expertise in Interdisciplinary problem-solving processes.

title	Digital Design - Research and Practice
source	Proceedings of the 10th International Conference on Computer Aided Architectural Design Futures / ISBN 1-4020-1210-1 / Tainan (Taiwan) 13–15 October 2003, 464 p.
summary	The use of computers in the design of the built environment has reached a watershed. From peripheral devices in the design process, they have in recent years come to take centre stage. An illustration is immediately at hand. Just as the entries to the competition for the Chicago Tribune Tower in 1922 defined the state-of-the-art at the beginning of the twentieth century, we have a similar marker at the end of the century, the competition in 2002 to replace the World Trade Centre towers in Lower Manhattan offered us a range of architectural solutions that exemplified the state-of-the-art eighty years later, setting forth not only architectural statements but also illustrating clearly the importance of computers in the design of the built environment. In these entries of 2002, we can see that computers have not only become essential to the communication of design but in the investigation and generation of structure, form and composition. The papers in this book are the current state-of-the-art in computer-aided design as it stands in 2003. It is the tenth in a series sponsored by the CAAD Futures Foundation, compiled from papers presented at the biennial CAAD Futures Conferences. As a series, the publications have charted the steady progress in developing the theoretical and practical foundations for applications in design practice. This volume continues in that tradition; thus, this book is entitled Digital Design: Research and Practice. The papers are grouped into three major categories, reflecting thrusts of research and practice, namely: Data and information: its organisation, handling and access, including agents; Virtual worlds: their creation, application and interfaces; and Analysis and creation of form and fabric. The editors received 121 abstracts after the initial call for contributions. From these, 61 abstracts were selected for development into complete papers for further review. From these submissions, 39 papers were chosen for inclusion in this publication. These papers show that the field has evolved from theoretical and development concerns to questions of practice in the decade during which this conference has showcased leading work. Questions of theoretical nature remain as the boundaries of our field expand. As design projects have grasped the potentials of computer-aided design, so have they challenged the capabilities of the tools. Papers here address questions in geometric representation and manipulation (Chiu and Chiu; Kocaturk, Veltkamp and Tuncer), topics that may have been considered to be solved. As design practice becomes increasingly knowledge based, better ways of managing, manipulating and accessing the complex wealth of design information becomes more pressing, demanding continuing research in issues such as modelling (Yang; Wang; Zreik et al), data retrieval and querying (Hwang and Choi; Stouffs and Cumming; Zreik, Stouffs, Tuncer, Ozsariyildiz and Beheshti), new modes of perceiving data (Segers; Tan). Tools are needed to manage, mine and create information for creative work, such as agents (Liew and Gero; Smith; Caneparo and Robiglio; Ding et al) or to support design processes (Smith; Chase). Systems for the support and development of designs continue (Gero; Achten and Jessurun). As progress is made on some fronts, such as user interfaces, attention is again turned to previously research areas such as lighting (Jung, Gross and Do; Ng et al; Wittkopf; Chevier; Glaser, Do and Tai) or services (Garcia; Chen and Lin). In recent years the growth of connectivity has led to a rapid growth in collaborative experience and understanding of the opportunities and issues continues to mature (Jabi; Dave; Zamenopoulos and Alexiou). Increasing interest is given to implications in practice and education (Dave; Oxman; Caneparo, Grassi and Giretti). Topics new to this conference are in the area of design to production or manufacture (Fischer, Burry and Frazer; Shih). Three additional invited papers (Rekimoto; Liu; Kalay) provide clear indication that there is still room to develop new spatial concepts and computer augmented environments for design. In conclusion, we note that these papers represent a good record of the current state of the evolving research in the field of digital design.

title	Modulating Thermal Mass Behavior Through Surface Figuration
source	ACADIA 2017: DISCIPLINES & DISRUPTION [Proceedings of the 37th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-0-692-96506-1] Cambridge, MA 2-4 November, 2017), pp. 202-211
doi	https://doi.org/10.52842/conf.acadia.2017.202
summary	This research builds upon a previous body of work focused on the relationship between surface geometry and heat transfer coefficients in thermal mass passive systems. It argues for the design of passive systems with higher fidelity to multivariable space between performance and perception. Rooted in the combination of form and matter, the intention is to instrumentalize design principles for the choreography of thermal gradients between buildings and their environment from experiential, spatial and topological perspectives (Figure 1). Our work is built upon the premise that complex geometries can be used to improve both the aesthetic and thermodynamic performance of passive building systems (Cupkova and Azel 2015) by actuating thermal performance through geometric parameters primarily due to convection. Currently, the engineering-oriented approach to the design of thermal mass relies on averaged thermal calculations (Holman 2002), which do not adequately describe the nuanced differences that can be produced by complex three-dimensional geometries of passive thermal mass systems. Using a combination of computational fluid dynamic simulations with physically measured data, we investigate the relationship of heat transfer coefficients related to parameters of surface geometry. Our measured results suggest that we can deliberately and significantly delay heat absorption re-radiation purely by changing the geometric surface pattern over the same thermal mass. The goal of this work is to offer designers a more robust rule set for understanding approximate thermal lag behaviors of complex geometric systems, with a focus on the design of geometric properties rather than complex thermal calculations.

title	Perceptual Evaluation of the Spatial Manifestations of Urban Structures
source	Environmental Simulation - New Impulses in Planning Processes [Proceedings of the 5th European Architectural Endoscopy Association Conference / ISBN 3-922602-85-1]
summary	The objective of this contribution is to bring to the attention of the community of experts in the field of architectural simulation the interdependence of the spatial manifestations of material components of urban environments and the phenomena of visual perception and imagination which we practically employ in education, professional design and which we also try to use in our contact with the clients. The way towards finding new qualities of urban environments should be dominated by our efforts to understand and perceive the urban structure as a real space-time manifestation, which is being mediated to the user also as a sensually experienced image (scene). Its atmosphere and informative content give impulses for an individualized reaction from various aspects. The content of the experience is multileveled and the sensorial effects of its iconic components can be precisely verified by means of simulation processes in temporal sequences. Taking these aspects as basis, we are developing methods, which would by taking determined conditions into consideration, broaden the spectrum of research, verification, or evaluation of the real spatial manifestations and interactive actions in situ as well as their possible anticipation and performance in laboratory conditions. Perceptual simulation is, together with the significance of experiencing and evaluating the urban environment in the eye-level horizon, a starting point of spatial model simulation methods as a supportive experimental creative and verification tool. The new information technologies and the creative technical cooperation of analog and digital iconic simulation systems create unconventional possibilities for exact recording of information and impulses for the complicated transformational process engaging more actively the community in their participation.

title	GIS Tools for Landscape Impact Assessment
source	Timmermans, Harry (Ed.), Sixth Design and Decision Support Systems in Architecture and Urban Planning - Part two: Urban Planning Proceedings Avegoor, the Netherlands), 2002
summary	This paper present the main results obtained by the development of the Artemis Project ”Design and Evaluation of Residential Patterns in the Mediterranan Region appropiate to sustainable development of environmentally deteriorated rural areas” 4th European Framework Program. Call ENVIRONMENT AND CLIMATE . ENV4-CT97-0656.) As results of the project an Integrated Landscape Assessment Model (AIAM) was created. AIAM is a resource modelling system focusing on the generation of a decision support system application oriented to provide criteria in order to evaluate effects and to optimise location of low density residential settlements. The Model includes a Landscape multicriteria analysis merged with spatial analysis tools set in a GIS Environment. The A.I.A.M. provides data structures, user interface components, and output mechanism witch allows the user to apply the knowledge acquired for Artemis Project. One of the main goals of the A.I.A.M is to give a landscape view of the territory including variables that are usually not considered in planning and environmental impact assessment processes. Also the models gives a sustainable support both to planner and designers projects. A.I.A.M. gives the data structure to define a residential patterns, the parameters through which a pattern is adequately described. This pattern definition allows comparison between the one’s of the reference area and so, extract conclusions about divergence between them.

title	Interaction in virtual building space, Distributing Knowledge in Building
source	CIB W78 Conference 2002, Proceedings, Vol. 2, pp91-98, Aarhus School of Architecture, Denmark, 12 –14 June
summary	This paper presents the results from two experiments in working on descriptions of form in immersive virtual environments (IVE). Recently; Virtual Environments (VE) are increasingly used as environments for design and research. Using VE to visualize ideas from the initial steps of design; the architect is challenged to deal with perception of space; solid and void; without translations to and from a two dimensional media. From this new ability; we might expect new forms of design interaction and expression. The goal of our studies was to identify how designers use and communicate early design ideas by using immersive three-dimensional (3D) VEs and how they describe 3D volumes using different media. We set up a series of experiments including navigation- and perception-tasks; designing in IVE; transcription of design; remote communication between design partners and controlled observations. We explored initial intentions of 3D-immersive design schemes; textual descriptions and collaborations within IVE. This paper describes the outcome of creation; interpretation and communication of architectural design; by using an Immersive Joint Design Studio; as well as the description and translation of a 3D cubic structure. We discuss frameworks and factors influencing how architectural students communicate their proposals in an immersive Virtual Environment Design Studio (VeDS) and how this approach of design studio enables to understand volumes and spatial relationships.

summary	Despite increasing interest in the functionality and humanization of architecture, scarcely the occupation of buildings are studied and it lacks methods to represent activities in the spaces. By this reason, it proposes a system such integrates simulation of processes and virtual modeling software, to program the behavior of tri-dimensional characters based on the probabilistic evolution of events, testing this approach in the study of emergency services of hospitals. It describes the procedure developed and reflections about temporal representation, demonstrating that modeling of activities allows to suggest functional and spatial improvements.

summary	Taking as a starting point the hypotheses that the urban body is a self-adapted ecology made of material and non-material components (Bateson, 1972), relationships between elements are examined in an attempt to destabilize the static division of matter and idea and to inquire into those relationships that determine the structural coupling (Maturana, 2002) between body and environment, as well as the constitution of the body itself. Contemporary technology is used in order to trace these alterations and the urban body is examined as a network configuration. The importance of the methodology adopted by the current research lies in the fact that social and economic factors merge with spatial characteristics, allowing for a visualization and re-interpretation of the urban body mutations based on self-adapted reconfigurations and for a prediction of the structural alterations made possible through the reconfiguration of the synaptic forces between elements.

summary	The project IDEA+ aims to develop an “Integrated Design Environment for Architecture”. Its goal is providing a tool for the designer-architect that can be of assistance in the early-design phases. It should provide the possibility to perform tests (like heat or cost calculations) and simple simulations in the different (early) design phases, without the need for a fully detailed design or remodeling in a different application. The test for daylighting is already in development (Geebelen, to be published). The conceptual foundation for this design environment has been laid out in a scheme in which different design phases and scales are defined, together with appropriate tests at the different levels (Neuckermans, 1992). It is a translation of the “designerly” way of thinking of the architect (Cross, 1982). This conceptual model has been translated into a “Core Object Model” (Hendricx, 2000), which defines a structured object model to describe the necessary building model. These developments form the theoretical basis for the implementation of IDEA+ (both the data structure & prototype software), which is currently in progress. The research project addresses some issues, which are at the forefront of the architect’s interest while designing with CAAD. These are treated from the point of view of a practicing architect.

doi	https://doi.org/10.52842/conf.acadia.2007.174
summary	This research proposes to support the reading of physical ambiences by the development of a representational technique which compiles, in a numerical interface, two types of data: sensory and filmic. These data are recorded through the use of a portable array equipped with sensors (Potvin 1997, 2002, 2004) as well as the acquisition of Video information of the moving environment. The compilation of information is carried out through a multi-media approach, by means of a program converting the environmental data into dynamic diagrams, as well as the creation of an interactive interface allowing a possible diffusion on the Web. This technique, named APMAP/Video, makes it possible to read out simultaneously spatial and environmental diversity. It is demonstrated through surveys taken at various seasons and time of the day at the new Caisse de dépôt et de placement headquarters in Montreal which is also the corpus for a SSHRC (Social Sciences and Humanities Research Council) research grant on Environmental Adaptability in Architecture (Potvin et al. 2003-2007). This case study shows that the technique can prove of great relevance for POEs (Post Occupancy Evaluation) as well as for assistance in a new design project.

doi	https://doi.org/10.52842/conf.ecaade.2002.042
summary	In a previous paper, the authors considered the design and development of virtual environments (VEs) pointing out the need for a new direction within architectural education, leading towards a generation of VE architects. It was suggested that there is an urgent need for educating practitioners who will contribute to the design of 3D content for multimedia and virtual reality applications. This paper focuses on the application of these principles and ideas into the structure and methodology of three VE design courses, taught by the authors. These courses are by no means suggested as exhaustive examples of teaching this subject. They are seen as preliminary approaches, adapting to the educational context they are integrated within. Bearing in mind the problems relating to teaching large numbers of students with a design studio approach, difficult concepts, resources availability, fighting misconceptions, techno-phobia the following areas are discussed in the hope that they will contribute to VE design curricula in the near future.

summary	‘Place’ is arguably an essential component of most successful virtual environments, yet the concept ofwhat is ‘place’, and what sort of ‘placeness’ is required for digital environments, are seldom discussed.A reflexive argument such as here is a place because it was designed to be a place does not stimulatedesign guidelines for virtual places, and it certainly does not help us create and evaluate virtual placessuitable for audiences who vary in intention or in available technology. To articulate useful distinctionsbetween virtual places, this paper extends design guidelines proposed by Kalay and Marx, reshapesthem with the help of Relph’s definitions, into spatial visualisation and activity-based environments, andadds a further category, the hermeneutic. The paper also proposes a graduated matrix for selection ofplacemaking elements and for selecting a mode of representation appropriate to the design objective ofthe virtual environment, be it spatial, activity-based, or hermeneutic.

summary	The cyberspace upon physical space forms a new spatial structure to increase the influence on the urban fabric and the concept of space in architecture. Today, digital cities are being developed all over the world. By using a city metaphor, digital cities integrate urban information and create public spaces. How do digital cities directly connect to physical cities and become an imaginable city? Therefore, we argue that a new spatial analysis theory must be established for digital city, comparing with theories of disciplines, to find the explicitly spatial structures and relations in digital city upon physical city.

summary	Abstract. In this paper, we want to figure out the relations of complex semantics and syntax on five traditional Taiwanese cities in Chi’i’ng Dynasty by using a language approach. The issues of traditional Taiwanese central city in Chi’ing Dynasty had been interpreting by historical, social, and cultural research but had lacked the explicit construction of spatial structure on semantics-syntax. Therefore, we use a data modeling on knowledge level to describe the relationship between syntax and semantics. Through the research of Chi’ing Dynasty‘s history, we find out the spatial relations of Taiwanese traditional city to establish the functional categories of spatial structures. Then the language of semantics components and the meaning’s attributes are coded as logical statements to map the elements of syntax on architectural form, political vocabularies, spatial layout, and spatial myth. We argue that using this approach several social and spatial structures of cities can be clearly defined and understood.

title	Design space navigation in generative design systems
source	Automation in Construction 11 (1) (2002) pp. 1-22
summary	Generative design systems make it easier for designers to generate and explore design alternatives, but the amount of information generated during a design session can become very large. Intelligent navigation aids are needed if designers wish to access the information they generate with ease. We present a comprehensive approach to support information navigation in requirement-driven generative design systems, which gain their power form explicit representations of design requirements, which in turn add to the information generated by the system. Our approach takes into account studies dealing with human spatial cognition, wayfinding in physical environments, and information navigation in electronic media. We structure the information to be accessed in terms of a five-dimensional design space model that applies across generative design systems of the type considered here. The model structure supports basic generic navigation operations along its five dimensions. We validated the model in the context of the SEED-Layout system and used it to extend the built-in navigation tools of the system through novel ones, which we subjected to a limited usability study. The study suggests that these tools have promise and warrant further investigation.

title	Towards a multi-agent model for visualizing simulated user behavior to support the assessment of design performance
source	Automation in Construction 11 (2) (2002) pp. 135-145
summary	We introduce the outline of a multi-agent model that can be used for visualizing simulated user behavior to support the assessment of design performance. We will consider various performance indicators of building environments, which are related to user reaction to design decisions. This system may serve as a media tool in the design process for a better understanding of what the design will look like, especially for those cases where design or planning decisions will affect the behavior of individuals. The system is based on cellular automata and multi-agent simulation technology. The system simulates how agents move around in a particular 3D (or 2D) environment, in which space is represented as a lattice of cells. Agents represent objects or people with their own behavior, moving over the network. Each agent will be located in a simulated space, based on the cellular automata grid. Each iteration of the simulation is based on a parallel update of the agents conforming local rules. Agents positioned within an environment will need sensors to perceive their local neighborhood and some means with which to affect the environment. In this way, autonomous individuals and the interaction between them can be simulated by the system. As a result, designers can use the system to assess the likely consequences of their design decisions on user behavior. We think that the system provides a potentially valuable tool to support design and decision-making processes, related to user behavior in architecture and urban planning.

title	Perception Aspects in Underground Spaces using Intelligent Knowledge Modeling
source	Delft University of Technology
summary	The intensification, combination and transformation are main strategies for future spatial development of the Netherlands, which are stated in the Fifth Bill regarding Spatial Planning. These strategies indicate that in the future, space should be utilized in a more compact and more efficient way requiring, at the same time, re-evaluation of the existing built environment and finding ways to improve it. In this context, the concept of multiple space usage is accentuated, which would focus on intensive 4-dimensional spatial exploration. The underground space is acknowledged as an important part of multiple space usage. In the document 'Spatial Exploration 2000', the underground space is recognized by policy makers as an important new 'frontier' that could provide significant contribution to future spatial requirements.In a relatively short period, the underground space became an important research area. Although among specialists there is appreciation of what underground space could provide for densely populated urban areas, there are still reserved feelings by the public, which mostly relate to the poor quality of these spaces. Many realized underground projects, namely subways, resulted in poor user satisfaction. Today, there is still a significant knowledge gap related to perception of underground space. There is also a lack of detailed documentation on actual applications of the theories, followed by research results and applied techniques. This is the case in different areas of architectural design, but for underground spaces perhaps most evident due to their infancv role in general architectural practice. In order to create better designs, diverse aspects, which are very often of qualitative nature, should be considered in perspective with the final goal to improve quality and image of underground space. In the architectural design process, one has to establish certain relations among design information in advance, to make design backed by sound rationale. The main difficulty at this point is that such relationships may not be determined due to various reasons. One example may be the vagueness of the architectural design data due to linguistic qualities in them. Another, may be vaguely defined design qualities. In this work, the problem was not only the initial fuzziness of the information but also the desired relevancy determination among all pieces of information given. Presently, to determine the existence of such relevancy is more or less a matter of architectural subjective judgement rather than systematic, non-subjective decision-making based on an existing design. This implies that the invocation of certain tools dealing with fuzzy information is essential for enhanced design decisions. Efficient methods and tools to deal with qualitative, soft data are scarce, especially in the architectural domain. Traditionally well established methods, such as statistical analysis, have been used mainly for data analysis focused on similar types to the present research. These methods mainly fall into a category of pattern recognition. Statistical regression methods are the most common approaches towards this goal. One essential drawback of this method is the inability of dealing efficiently with non-linear data. With statistical analysis, the linear relationships are established by regression analysis where dealing with non-linearity is mostly evaded. Concerning the presence of multi-dimensional data sets, it is evident that the assumption of linear relationships among all pieces of information would be a gross approximation, which one has no basis to assume. A starting point in this research was that there maybe both linearity and non-linearity present in the data and therefore the appropriate methods should be used in order to deal with that non-linearity. Therefore, some other commensurate methods were adopted for knowledge modeling. In that respect, soft computing techniques proved to match the quality of the multi-dimensional data-set subject to analysis, which is deemed to be 'soft'. There is yet another reason why soft-computing techniques were applied, which is related to the automation of knowledge modeling. In this respect, traditional models such as Decision Support Systems and Expert Systems have drawbacks. One important drawback is that the development of these systems is a time-consuming process. The programming part, in which various deliberations are required to form a consistent if-then rule knowledge based system, is also a time-consuming activity. For these reasons, the methods and tools from other disciplines, which also deal with soft data, should be integrated into architectural design. With fuzzy logic, the imprecision of data can be dealt with in a similar way to how humans do it. Artificial neural networks are deemed to some extent to model the human brain, and simulate its functions in the form of parallel information processing. They are considered important components of Artificial Intelligence (Al). With neural networks, it is possible to learn from examples, or more precisely to learn from input-output data samples. The combination of the neural and fuzzy approach proved to be a powerful combination for dealing with qualitative data. The problem of automated knowledge modeling is efficiently solved by employment of machine learning techniques. Here, the expertise of prof. dr. Ozer Ciftcioglu in the field of soft computing was crucial for tool development. By combining knowledge from two different disciplines a unique tool could be developed that would enable intelligent modeling of soft data needed for support of the building design process. In this respect, this research is a starting point in that direction. It is multidisciplinary and on the cutting edge between the field of Architecture and the field of Artificial Intelligence. From the architectural viewpoint, the perception of space is considered through relationship between a human being and a built environment. Techniques from the field of Artificial Intelligence are employed to model that relationship. Such an efficient combination of two disciplines makes it possible to extend our knowledge boundaries in the field of architecture and improve design quality. With additional techniques, meta know/edge, or in other words "knowledge about knowledge", can be created. Such techniques involve sensitivity analysis, which determines the amount of dependency of the output of a model (comfort and public safety) on the information fed into the model (input). Another technique is functional relationship modeling between aspects, which is derivation of dependency of a design parameter as a function of user's perceptions. With this technique, it is possible to determine functional relationships between dependent and independent variables. This thesis is a contribution to better understanding of users' perception of underground space, through the prism of public safety and comfort, which was achieved by means of intelligent knowledge modeling. In this respect, this thesis demonstrated an application of ICT (Information and Communication Technology) as a partner in the building design process by employing advanced modeling techniques. The method explained throughout this work is very generic and is possible to apply to not only different areas of architectural design, but also to other domains that involve qualitative data.
