title	Optimise Urban Daylight Design Using Computational Simulations
source	Architecture in the Network Society [22nd eCAADe Conference Proceedings / ISBN 0-9541183-2-4] Copenhagen (Denmark) 15-18 September 2004, pp. 318-324

summary	Urban design is about providing an infrastructure for its inhabitants. An important consideration of design is to provide natural outdoor conditions that are pleasant and conductive to human activities. A well designed outdoor urban environment will also make the design of individual buildings within it easier. There are many design parameters, for example: Development Density, Plot ratio, Site Coverage, Skyline, Building to Space Ratio, Permeability, Building Shapes and so on. This paper reports a study based on „skylines“ as a design parameter, and how it affects daylight and natural ventilation provisions and performance. Experiments are conducted with physical models in artificial sky, as well as using computational lighting simulations. The study establishes that by varying the skylines of the city, the overall daylight performances could be improved when compared to a city with a uniform skyline - given the same density. The message of the paper is that: through better understanding and design, high density cities could be planned and optimised without losing the development efficacy of the land.

title	Application of Genetic Algorithms to Establish Flooding Evacuation Path Model in Metropolitan Area
source	CAADRIA 2004 [Proceedings of the 9th International Conference on Computer Aided Architectural Design Research in Asia / ISBN 89-7141-648-3] Seoul Korea 28-30 April 2004, pp. 557-570

summary	This research has shown the difficulties associated with the GIS and the flooding evacuation path search through the huge searching space generated during the network analysis process. This research also presents an approach to these problems by utilizing a search process whose concept is derived from natural genetics. Genetic algorithms (GAs) have been introduced in the optimization problem solving area by Holland (1975) and Goldberg (1989) and have shown their usefulness through numerous applications. We apply GA and GIS to choice flooding evacuation path in metropolitan area in this study. We take the region of Shiji city in Taiwan for case. That could be divided into four parts. First, is to set the population of GA operation. Second, is to choose crossover and mutation. Third, is to calculate the fitness function of each generation and to select the better gene arrangement. Fourth, is to reproduce, after evolution, we can establish Flooding Evacuation Path that more reflect really human action and choice when flood takes place. However we can apply GA to calculate different evacuation path in different time series. Final, we compare and establish real model of evacuation path model to choosing flooding evacuation path.

title	Crowd Modeling and Simulation
source	Van Leeuwen, J.P. and H.J.P. Timmermans (eds.) Recent Advances in Design & Decision Support Systems in Architecture and Urban Planning, Dordrecht: Kluwer Academic Publishers, ISBN: 1-4020-2408-8, p. 161-175
summary	The paper introduces a Multi Agent Systems (MAS) approach to crowd modelling and simulation, based on the Situated Cellular Agents (SCA) model. This is a special class of Multilayered Multi Agent Situated System (MMASS), exploiting basic elements of Cellular Automata. In particular SCA model provides an explicit spatial representation and the definition of adjacency geometries, but also a concept of autonomous agent, provided with an internal architecture, an individual state and behaviour. The latter provides different means of space-mediated interaction among agents: synchronous, between adjacent agents, and asynchronous among at-a-distance entities. Heterogeneous entities may be modelled through the specification of different agent types, defining different behaviours and perceptive capabilities. After a brief description of the model, its application to simple crowd behaviours will be given, and an application providing the integration of a bidimensional simulator based on this model and a 3D modelling application (3D Studio) will also be described. The adoption of this kind of system allows the specification and simulation of an architectural design with reference to the behaviour of entities that will act in it. The system is also able to easily produce a realistic visualization of the simulation, in order to facilitate the evaluation of the design and the communication with involved decision-makers. In fact, while experts often require only abstract and analytical results deriving from a quantitative analysis of simulation results, other people involved in the decision-making process related to the design may be helped by qualitative aspects better represented by other forms of graphical visualization.

title	A Spatial Decision Support System for the Management of Public Housing
source	Van Leeuwen, J.P. and H.J.P. Timmermans (eds.) Recent Advances in Design & Decision Support Systems in Architecture and Urban Planning, Dordrecht: Kluwer Academic Publishers, ISBN: 1-4020-2408-8, p. 69-84
summary	This paper is reporting on a research project undertaken jointly between the University of New South Wales (UNSW) and the NSW Department of Housing (DoH) to develop a Spatial Decision Support System (SDSS) to assist planning, management and evaluation in areas of high public housing concentration. In the paper we will describe the development of the SDSS, the specific spatial problems challenging the DoH and the potential for the system to incorporate a range of social, financial and physical data, both internal and from other sources, for interaction and presentation in a three dimensional environment. The prototype SDSS attempts to address the specific challenges of providing better service for clients of the DoH. An information audit and survey has been conducted of the department’s resources and needs. Issues identified include the management of high-rise and superlot areas, crime mapping, community interactivity, internal and intergovernmental information sharing, interoperability and maintaining confidentiality and security of data. Interactive 3D visualisation of the model is facilitated by use of the 3map free geospace platform. Use of open source code and open standards such as X3D for 3D graphics interchange allow the project to explore advanced visualisation techniques while ensuring interoperability and data longevity.

doi	https://doi.org/10.52842/conf.caadria.2004.433
summary	This paper presents the observations of a design studio for undergraduates that adopted a hands-on, experiential approach where students combined both digital modeling and full-scale construction in their design process. The studio was designed as team-based to encourage peer learning and collaboration in design. The students used multiple media and engaged in tactile experience and through the process discovered by themselves the issues of translating digital design into full-scale construction and achieved a better understanding of construction, scale and materiality.

title	La Arquitectura como Extensión Fenotípica Humana - Un Acercamiento Basado en Análisis Computacionales [Architecture as human phenotypic extension – An approach based on computational explorations]
source	SIGraDi 2006 - [Proceedings of the 10th Iberoamerican Congress of Digital Graphics] Santiago de Chile - Chile 21-23 November 2006, pp. 56-60
summary	The study describes some of the aspects tackled within a current Ph.D. research where architectural applications of constructive, structural and organization processes existing in biological systems are considered. The present information processing capacity of computers and the specific software development have allowed creating a bridge between two holistic nature disciplines: architecture and biology. The crossover between those disciplines entails a methodological paradigm change towards a new one based on the dynamical aspects of forms and compositions. Recent studies about artificial-natural intelligence (Hawkins, 2004) and developmental-evolutionary biology (Maturana, 2004) have added fundamental knowledge about the role of the analogy in the creative process and the relationship between forms and functions. The dimensions and restrictions of the Evo-Devo concepts are analyzed, developed and tested by software that combines parametric geometries, L-systems (Lindenmayer, 1990), shape-grammars (Stiny and Gips, 1971) and evolutionary algorithms (Holland, 1975) as a way of testing new architectural solutions within computable environments. It is pondered Lamarck´s (1744-1829) and Weismann (1834-1914) theoretical approaches to evolution where can be found significant opposing views. Lamarck´s theory assumes that an individual effort towards a specific evolutionary goal can cause change to descendents. On the other hand, Weismann defended that the germ cells are not affected by anything the body learns or any ability it acquires during its life, and cannot pass this information on to the next generation; this is called the Weismann barrier. Lamarck’s widely rejected theory has recently found a new place in artificial and natural intelligence researches as a valid explanation to some aspects of the human knowledge evolution phenomena, that is, the deliberate change of paradigms in the intentional research of solutions. As well as the analogy between genetics and architecture (Estévez and Shu, 2000) is useful in order to understand and program emergent complexity phenomena (Hopfield, 1982) for architectural solutions, also the consideration of architecture as a product of a human extended phenotype can help us to understand better its cultural dimension.

summary	We consider program proposals as separate projects and use an incremental decision process (Incremental Functional Formulation) backed by methods of optimisation through incremental and interactive decision processes which have been developed in operations research. These methods fit the illstructured problems in planning better than the conventional optimisation methods. We'll conclude showing one of the possible concrete applications of our model to a real-life case, where one of the main results was a suggested expense of € 4 millions leading to the 90% of the result possible with the cost of € 10 millions (but with just a 40% expenditure).

title	Drawing the Map. About the Way Hand Drawings look in Computer Models
source	Spatial Simulation and Evaluation - New Tools in Architectural and Urban Design [Proceedings of the 6th European Architectural Endoscopy Association Conference / ISBN 80-227-2088-7], pp. 91-100
summary	The use of 3D-software in architecture has several advantages: architects and clients are better able to comprehend the design, test variants and take and confirm decisions. On the other hand, architects warn against the presentation of computer images at too early a stage because these images give the impression of conclusiveness. Hand-drawn illustrations, by contrast, have the loose character of a sketch and leave things open to the imagination. This has advantages, especially in the initial stages of a design. This paper is a survey of our current research and teaching work, showing especially the combination of freehand drawing and computer model and the effects and possibilities of this form of abstraction in order to facilitate a correct interpretation of the proposed ideas.

title	Communicating Concepts for Shared Understanding: A Multi-Agent Approach

summary	Capturing and sharing design concepts is necessary if we want to support the design process by means of Information & Communication Technology (ICT). Standardized concepts are important for support at the end of the design process when designs need to conform to set standards and norms, and in order to enable communication, but are less useful in the early design stages. We propose an approach that takes into account a more developmental attitude that will be better suited for design support and the sharing of design concepts. In this approach, design concepts are formalised by means of a technology called concept modelling. Capturing and exchange of concepts are based on a multi-agent approach. The whole of concepts that are used in a domain or for a design task can be considered a design ontology. In this paper we outline the motivations for the research, outline the basic approach in the research work, and identify the major challenges and research problems that need to be tackled.

title	A FRAMEWORK FOR COMPUTER-SUPPORTED COLLABORATION IN ARCHITECTURAL DESIGN
source	University of Michigan
summary	The development of appropriate research frameworks and guidelines for the construction of software aids in the area of architectural design can lead to a better understanding of designing and computer support for designing (Gero and Maher 1997). The field of research and development in computer-supported collaborative architectural design reflects that of the early period in the development of the field of computersupported cooperative work (CSCW). In the early 1990s, the field of CSCW relied on unsystematic attempts to generate software that increases the productivity of people working together (Robinson 1992). Furthermore, a shift is taking place by which researchers in the field of architecture are increasingly becoming consumers of rather than innovators of technology (Gero and Maher . In particular, the field of architecture is rapidly becoming dependent on commercial software implementations that are slow to respond to new research or to user demands. Additionally, these commercial systems force a particular view of the domain they serve and as such might hinder rather than help its development. The aim of this dissertation is to provide information to architects and others to help them build their own tools or, at a minimum, be critical of commercial solutions.

title	CONTEXTUALIZATION AND EMBODIMENT IN CYBERSPACE

summary	The introduction of VRML (Virtual Reality Markup Language) in 1994, and other similar web-enabled dynamic modeling software (such as SGI’s Open Inventor and WebSpace), have created a rush to develop on-line 3D virtual environments, with purposes ranging from art, to entertainment, to shopping, to culture and education. Some developers took their cues from the science fiction literature of Gibson (1984), Stephenson (1992), and others. Many were web-extensions to single-player video games. But most were created as a direct extension to our new-found ability to digitally model 3D spaces and to endow them with interactive control and pseudo-inhabitation. Surprisingly, this technologically-driven stampede paid little attention to the core principles of place-making and presence, derived from architecture and cognitive science, respectively: two principles that could and should inform the essence of the virtual place experience and help steer its development. Why are the principles of place-making and presence important for the development of virtual environments? Why not simply be content with our ability to create realistically-looking 3D worlds that we can visit remotely? What could we possibly learn about making these worlds better, had we understood the essence of place and presence? To answer these questions we cannot look at place-making (both physical and virtual) from a 3D space-making point of view alone, because places are not an end unto themselves. Rather, places must be considered a locus of contextualization and embodiment that ground human activities and give them meaning. In doing so, places acquire a meaning of their own, which facilitates, improves, and enriches many aspects of our lives. They provide us with a means to interpret the activities of others and to direct our own actions. Such meaning is comprised of the social and cultural conceptions and behaviors imprinted on the environment by the presence and activities of its inhabitants, who in turn, ‘read’ by them through their own corporeal embodiment of the same environment. This transactional relationship between the physical aspects of an environment, its social/cultural context, and our own embodiment of it, combine to create what is known as a sense of place: the psychological, physical, social, and cultural framework that helps us interpret the world around us, and directs our own behavior in it. In turn, it is our own (as well as others’) presence in that environment that gives it meaning, and shapes its social/cultural character. By understanding the essence of place-ness in general, and in cyberspace in particular, we can create virtual places that can better support Internet-based activities, and make them equal to, in some cases even better than their physical counterparts. One of the activities that stands to benefit most from understanding the concept of cyber-places is learning—an interpersonal activity that requires the co-presence of others (a teacher and/or fellow learners), who can point out the difference between what matters and what does not, and produce an emotional involvement that helps students learn. Thus, while many administrators and educators rush to develop webbased remote learning sites, to leverage the economic advantages of one-tomany learning modalities, these sites deprive learners of the contextualization and embodiment inherent in brick-and-mortar learning institutions, and which are needed to support the activity of learning. Can these qualities be achieved in virtual learning environments? If so, how? These are some of the questions this talk will try to answer by presenting a virtual place-making methodology and its experimental implementation, intended to create a sense of place through contextualization and embodiment in virtual learning environments.

title	SPATIAL SIMULATION AND EVALUATION - NEW TOOLS IN ARCHITECTURAL AND URBAN DESIGN
source	Proceedings of the 6th European Architectural Endoscopy Association Conference / ISBN 80-227-2088-7, 144 p.
summary	The 5th eaea Conference in Essen yielded four principal findings: • After having been limited to endoscopic picture and film renderings of analog scaled models, the european architectural endoscopy association (eaea) first bridged the gap to digital environmental simulations at this conference. It is not about a better or correct method, but a suitable method of representing the planned reality of a particular project using ways that make sense. The combination of digital and analog simulation media is a source of impetus to the user of both methods. The future belongs to the casespecific application and the numerous integration possibilities of the two different media. • In investigating the perception of pictures produced in both analog and digital form, it was ascertained that it was only after greater effort that the same level of pleasing qualities were achieved in the digital world, compared to pictures of analog scaled models. It seems that for many planning phases model-based pictures are superior to digital photos – with regards to economy, quality of representation and imaginative attributes. This last point seems to be especially important in the draft planning stages: the less sharp a picture is, the more remaining room for viewer interpretation there is. In particular, the high degree of precision characteristic of digital simulations no longer allows room for imagination in the individual viewer. • 3D environmental simulations will increasingly be incorporated with success in architecture and urban design courses at universities and colleges both here in Germany as well as abroad. The further spread of these techniques to other universities and colleges is desirable. Over and above application as a pedagogic tool, the use of these simulations by architects and city planners, private planning agencies and municipal planning administrators will also be in evidence in the future – for checking designs, for informing the involved parties, for establishing the decisions of government bodies, for marketing the project. • Also, the interactive use of endoscopic simulation facilities continually opens new fields of research – whether it be for registering subjective distance perception, whether it be for determining orientation possibilities in open spaces.

title	The promise of peer-to-peer computing versus the utility of centralised data models in collaborative design
source	LOCAL VALUES in a NETWORKED DESIGN WORLD - ADDED VALUE OF COMPUTER AIDED ARCHITECTURAL DESIGN, Stellingwerff, Martijn and Verbeke, Johan (Eds.), (2004) DUP Science - Delft University Press, ISBN 90-407-2507-1.
summary	Peer-to-peer (P2P), or distributed computing, involves having computers on a net¬work -peers- acting as both suppliers, as well as consumers of information. With recent developments, most notably the JXTA initiative by Sun Microsystems, such P2P technology will soon become quite easy to implement, in a standardised and secure fashion. P2P technology holds promise in the domain of collaborative design in that it allows design collaborators to exchange information in a manner that appears to have certain advantages over centralised systems, such as greater spontaneity, the ability to self-organize, better scalability, and the ability to handle transient resources in a more robust manner. However, it is not clear how this new technology can be applied to the information needs of collaborative design, in which centralised data models are usually seen as useful. This paper examines some of the positive and negative implications of this new technology in the context of collaborative design.

summary	Mesh segmentation has become an important and well-researched topic in computational geometry in recent years (Agathos et al. 2008). As a result, a number of new approaches have been developed that have led to innovations in a diverse set of problems in computer graphics (CG) (Sharmir 2008). Specifically, a range of effective methods for the division of a mesh have recently been proposed, including by K-means (Shlafman et al. 2002), graph cuts (Golovinskiy and Funkhouser 2008; Katz and Tal 2003), hierarchical clustering (Garland et al. 2001; Gelfand and Guibas 2004; Golovinskiy and Funkhouser 2008), primitive fitting (Athene et al. 2004), random walks (Lai et al.), core extraction (Katz et al.) tubular multi-scale analysis (Mortara et al. 2004), spectral clustering (Liu and Zhang 2004), and critical point analysis (Lin et al. 20070, all of which depend upon a weighted graph representation, typically the dual of a given mesh (Sharmir 2008). While these approaches have been proven effective within the narrowly defined domains of application for which they have been developed (Chen 2009), they have not been brought to bear on wider classes of problems in fields outside of CG, specifically on problems relevant to generative architectural design. Given the widespread use of meshes and the utility of segmentation in GAD, by surveying the relevant and recently matured approaches to mesh segmentation in CG that share a common representation of the mesh dual, this paper identifies and takes steps to address a heretofore unrealized transfer of technology that would resolve a missed opportunity for both subject areas. Meshes are often employed by architectural designers for purposes that are distinct from and present a unique set of requirements in relation to similar applications that have enjoyed more focused study in computer science. This paper presents a survey of similar applications, including thin-sheet fabrication (Mitani and Suzuki 2004), rendering optimization (Garland et al. 2001), 3D mesh compression (Taubin et al. 1998), morphin (Shapira et al. 2008) and mesh simplification (Kalvin and Taylor 1996), and distinguish the requirements of these applications from those presented by GAD, including non-refinement in advance of the constraining of mesh geometry to planar-quad faces, and the ability to address a diversity of mesh features that may or may not be preserved. Following this survey of existing approaches and unmet needs, the authors assert that if a generalized framework for working with graph representations of meshes is developed, allowing for the interactive adjustment of edge weights, then the recent developments in mesh segmentation may be better brought to bear on GAD problems. This paper presents work toward the development of just such a framework, implemented as a plug-in for the visual programming environment Grasshopper.

summary	The assessment of architectural design project work, which forms the majority of the work produced by students in schools of architecture, is usually assessed through the process of critical review (otherwise known as a ‚crit‘ or jury). The traditional method of critical review usually involves the student describing work displayed on a wall directly in front of a panel of critics. Difficulties emerge when students wish to incorporate dynamic, computer generated content into their presentations. Architectural practice is increasingly turning to the ‘PowerPoint’ slide show as a means to communicate their work to clients, and this technology is often better able to incorporate dynamic content. This paper describes a comparative study, whereby students work is presented in both slideshow and pin-up formats to a panel of reviewers. The reviewers were able to evaluate the value of the two forms of presentation in terms of their ability to conduct critical reviews. Results suggest that whilst the slideshow method allows the reviewers to gain a reasonable understanding of the student’s project work, they found it more difficult to provide useful feedback to the student on their design project work.

summary	The constant advances in the use of computers to simulate light over the past few decades, has led computer-aided rendering to become increasingly photorealistic. However, the rendering is still processor-intensive and time-consuming, difficult to generate in real time. Design students need to be well versed in the depiction of the effects of light in an environment, crucial to spatial visualization. With increasing computing power, advanced algorithms and increased realism, the central pedagogical issue in their use is not what computers can do for us today, but what and how we can make them do what we do better. We have to be careful in not getting seduced by the advancing technology but use it innovatively to build students into better designers. This paper discusses a project demonstrating the apparent potential of computers for spatial visualization and design exploration of light and space, in their present stage. The project shows a departure from the traditional methods of using computers or of teaching lighting in a design school. Computers are used by students to especially create flashy imagery. On the other hand, lighting is explained in clinical terms without exploration of its experiential qualities. This exercise helped the students to develop a better understanding of the physics of light from the method most familiar and expected of students – visual. The project deems it more important to have a quick means to produce an overview of the implication of the design choices than to provide precise information regarding a hypothetical final solution. Hence, after creating the lighting in the space based on the desired experiential qualities, the illumination can be conveyed to a lighting expert for detailed quantitative computations. The project results are shown and outcomes discussed.

summary	In this age of information revolution, design professionals are looking forward to exploring new methods and tools that could help them in delivering better designs and particularly understanding and incorporating of code-compliant design provisions in their projects. Automation of building code analysis is a vital factor in leveraging building codes from what is as a textual legal document to more graphical interactive source of building criteria. The argument of the paper will be based on the International Building Code (IBC) which is issued by the International Code Council (ICC) and considered as the most comprehensive and coordinated national model code in the US and is currently commonly used and enforced in 44 states. The paper will also examine and report on the purpose, types, interpretation, understanding and use of building codes applied in the United States; evaluation of recent research activities on automation of building code analysis; evaluation of current building code analysis tools; and a conceptual framework of a Computer-Aided Analysis of Design (CAAnD) program for building codes that could assist design professionals during project design development.

title	3D Reconstruction of a Canaletto Painting

summary	The objective of this research was the analysis of a Canaletto painting that depicts Palladio’s plan for the „Convento della Carità“ in Venice, a plan that was only partially executed. Through the implementation of traditional techniques and digitally controlled instruments, the three dimensional model was reconstructed. It was compared with both Palladio’s original plan, and with the constructed version. A notable difference between the three projects emerged which allowed for a better comprehension- using photogrammetric restitution procedures- of Canaletto’s pictorial work and the corrections that the painter brought to the piece to improve the rendition of the painting. The study ends with an analysis of the natural light painted by Canaletto, and a simulation of sunlight with digital techniques.

title	A Nobel Prize for CAAD
source	International Journal of Architectural Computing vol. 2 - no. 1
summary	Fundamental questions about the status of CAAD research arise regularly on different levels and under different circumstances. Apparently there is no common understanding about this, causing confusion, which in itself is already bad for the status of CAAD research. In this article I will discuss the CAAD research approach as I find it at most architecture and engineering groups, by comparing it to research in the traditional science domain. Some differences can be explained from the nature of design, but others' have more historical reasons. To conclude I propose a long-term strategy for scientific CAAD research, namely: (i) Build your own community, (ii) Establish prestigious journals and prizes and (iii) Improve quality by natural selection. Eventually this will bring us the recognition for CAAD research that it deserves.

title	COMPUTER DESIGN OF REPEATING HYPERBOLIC PATTERNS
source	Proceedings of the Fourth International Conference of Mathematics & Design, Special Edition of the Journal of Mathematics & Design, Volume 4, No.1, pp. 83-90.
summary	From antiquity, humans have created 2-dimensional art on flat surfaces (the Euclidean plane) and on surfaces of spheres. However, it wasn't until about 50 years ago that designers have created art in the third "classical geometry", the hyperbolic plane. Inspired by a diagram from the mathematician H. S. M. Coxeter, the graphic artist M. C. Escher became the first person to design such patterns, performing all the needed constructions laboriously by hand. In order to exhibit the true hyperbolic nature of such art, the pattern must exhibit symmetry and repetition. It seems natural to use a computer to avoid the tedious hand constructions performed by Escher. This was our goal: to design and implement a computer program to create repeating hyperbolic patterns.
