title	Evolving Urban Structures using Computational Optimisation
source	Proceedings of the Generative Arts conference, Milan, 2006
summary	This paper investigates the use of computer analogies for naturally inspired optimisation techniques as an aid to developing the site layout and massing for the new World Trade Centre development in Pristina Kosovo, which is being designed and developed by 4M Group architectural company, in conjunction with the Advanced Modelling Group Aedas. The development of a genetic algorithm will incorporate various techniques, that have been developed in the field of multi-objective optimisation, to create three dimensional massing models, and site layout solutions which partially fulfil the Prisina brief requirements, which are taken from specifications created by 4M Group. Genetic algorithms are based on natural evolutionary principles which are explained in this paper. It will incorporate Pareto concepts to manage the optimisation of the various objective functions. For example, these will include volume and position of units, which will ensure that the different and sometime conflicting needs of the site are balanced throughout the optimisation. This type of problem is often known as an NP-complete (non-determinate polynomial time) problem. This will provide architects and planners with a number of Pareto optimised site massing solutions as an aid to the design process. An initial investigation into the specifics of the Pristina site requirements, will be followed by an investigation into the the genetic algorithm which is created in Visual Basic for Applications (VBA) linked with AutoCAD as the graphical output of the code. The embryology (development) of the various solutions from the genetic information incorporates an ‘ant’ pheromone trail model, which simulates the action of ants during food foraging, as a tool for initial route planning within the site. Diffusion and cellular automata are used during the development of the solution to construct the massing for the site.

title	A Method for Estimating Land Use Transition Probability Using Raster Data - Considerations about apatial unit of transition, fixed state of locations, and time-varying probability
source	Van Leeuwen, J.P. and H.J.P. Timmermans (eds.) 2006, Innovations in Design & Decision Support Systems in Architecture and Urban Planning, Dordrecht: Springer, ISBN-10: 1-4020-5059-3, ISBN-13: 978-1-4020-5059-6, p. 69-84
summary	In the field of urban and regional planning, several Markov chain models for land use conversion have been proposed. However, some problems have been encountered when estimating land use transition probabilities. In this paper, a new estimation method to determine land use transition probability is proposed by taking into account spatial units of land use transition, fixed state of locations, and varying transition probabilities. The effectiveness of the proposed methods and some new findings on land use conversion are presented using numerical examples.

title	An Analysis of the Applications of Rapid Prototyping in Architecture
source	Computing in Architecture / Re-Thinking the Discourse: The Second International Conference of the Arab Society for Computer Aided Architectural Design (ASCAAD 2006), 25-27 April 2006, Sharjah, United Arab Emirates
summary	Rapid prototyping (RP) techniques are widely used within the design/manufacturing industry and are well established in manufacturing industry. These digital techniques offer quick and accurate prototypes with relatively low cost when we require exact likeness to a particular scale and detail. 3D modeling of buildings on CAD-systems in the AEC sector is now becoming more popular and becoming widely used practice as the higher efficiency of working with computers is being recognized. However the building of scaled physical representations is still performed manually, which generally requires a high amount of time. Complex post-modernist building forms are more faithfully and easily represented in a solid visualization form, than they could be using traditional model making methods. Using RP within the engineering community has given the users the possibility to communicate and visualize designs with greater ease with the clients and capture any error within the CAD design at an early stage of the project or product lifecycle. In this paper, the application of RP in architecture is reviewed and the possibilities of modeling architectural models are explored. A methodology of developing rapid prototypes with 3D CAD models using methods of solid freeform manufacturing in particular Fused Deposition Modeling (FDM) is presented and compared against traditional model making methods. An economical analysis is presented and discussed using a case study and the potential of applying RP techniques to architectural models is discussed.

title	Bidirectional Interoperability Between CAD and Energy Performance Simulation Through Virtual Model System Framework
source	Synthetic Landscapes [Proceedings of the 25th Annual Conference of the Association for Computer-Aided Design in Architecture] pp. 232-250
doi	https://doi.org/10.52842/conf.acadia.2006.232
summary	The paper describes a novel approach involving interoperability, data modeling technology, and application of the building information model (BIM) focused on sustainable architecture. They share relationships and multiple experiences that have existed for years but have never have been proven. This interoperability of building performance simulation maps building information and parametric models with energy simulation models, establishing a seamless link between Computer Aided Design (CAD) and energy performance simulation software. During the last four decades, building designers have utilized information and communication technologies to create environmental representations to communicate spatial concepts or designs and to enhance spaces. Most architectural firms still rely on hand labor, drafted drawings, construction documents, specifications, schedules and work plans in traditional means. 3D modeling has been used primarily as a rendering tool, not as the actual representation of the project.With this innovative digitally exchange technology, architects and building designers can visually analyze dynamic building energy performance in response to changes of climate and building parameters. This software interoperability provides full data exchange bidirectional capabilities, which significantly reduces time and effort in energy simulation and data regeneration. Data mapping and exchange are key requirements for building more powerful energy simulations. An effective data model is the bidirectional nucleus of a well-designed relational database, critical in making good choices in selecting design parameters and in gaining and expanding a comprehensive understanding of existing data flows throughout the simulation process, making data systems for simulation more powerful, which has never been done before. Despite the variety of energy simulation applications in the lifecycle of building design and construction projects, there is a need for a system of data integration to allow seamless sharing and bidirectional reuse of data.

title	Road hierarchy and speed limits in Brasília/Brazil
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 aims at exploring the theory of the Social Logic of Space or Space Syntax as a strategy to define parameters of road hierarchy and, if this use is found possible, to establish maximum speeds allowed in the transportation system of Brasília, the capital city of Brazil. Space Syntax – a theory developed by Hillier and Hanson (1984) – incorporates the space topological relationships, considering the city shape and its influence in the distribution of movements within the space. The theory’s axiality method – used in this study – analyses the accessibility to the street network relationships, by means of the system’s integration, one of its explicative variables in terms of copresence, or potential co-existence between the through-passing movements of people and vehicles (Hillier, 1996). One of the most used concepts of Space Syntax in the integration, which represents the potential flow generation in the road axes and is the focus of this paper. It is believed there is a strong correlation between urban space-form configuration and the way flows and movements are distributed in the city, considering nodes articulations and the topological location of segments and streets in the grid (Holanda, 2002; Medeiros, 2006). For urban transportation studies, traffic-related problems are often investigated and simulated by assignment models – well-established in traffic studies. Space Syntax, on the other hand, is a tool with few applications in transport (Barros, 2006; Barros et al, 2007), an area where configurational models are considered to present inconsistencies when used in transportation (cf. Cybis et al, 1996). Although this is true in some cases, it should not be generalized. Therefore, in order to simulate and evaluate Space Syntax for the traffic approach, the city of Brasília was used as a case study. The reason for the choice was the fact the capital of Brazil is a masterpiece of modern urban design and presents a unique urban layout based on an axial grid system considering several express and arterial long roads, each one with 3 to 6 lanes,

title	A strategy for complex-curved building design:Design structure with Bi-lateral contouring as integrally connected ribs
source	SIGraDi 2006 - [Proceedings of the 10th Iberoamerican Congress of Digital Graphics] Santiago de Chile - Chile 21-23 November 2006, pp. 465-469
summary	Shapes in designs created by architects such as Gehry Partners (Shelden, 2002), Foster and Partners, and Kohn Peterson and Fox rely on computational processes for rationalizing complex geometry for building construction. Rationalization is the reduction of a complete geometric shape into discrete components. Unfortunately, for many architects the rationalization is limited reducing solid models to surfaces or data on spread sheets for contractors to follow. Rationalized models produced by the firms listed above do not offer strategies for construction or digital fabrication. For the physical production of CAD description an alternative to the rationalized description is needed. This paper examines the coupling of digital rationalization and digital fabrication with physical mockups (Rich, 1989). Our aim is to explore complex relationships found in early and mid stage design phases when digital fabrication is used to produce design outcomes. Results of our investigation will aid architects and engineers in addressing the complications found in the translation of design models embedded with precision to constructible geometries. We present an algorithmically based approach to design rationalization that supports physical production as well as surface production of desktop models. Our approach is an alternative to conventional rapid prototyping that builds objects by assembly of laterally sliced contours from a solid model. We explored an improved product description for rapid manufacture as bilateral contouring for structure and panelling for strength (Kolarevic, 2003). Infrastructure typically found within aerospace, automotive, and shipbuilding industries, bilateral contouring is an organized matrix of horizontal and vertical interlocking ribs evenly distributed along a surface. These structures are monocoque and semi-monocoque assemblies composed of structural ribs and skinning attached by rivets and adhesives. Alternative, bi-lateral contouring discussed is an interlocking matrix of plywood strips having integral joinery for assembly. Unlike traditional methods of building representations through malleable materials for creating tangible objects (Friedman, 2002), this approach constructs with the implication for building life-size solutions. Three algorithms are presented as examples of rationalized design production with physical results. The first algorithm [Figure 1] deconstructs an initial 2D curved form into ribbed slices to be assembled through integral connections constructed as part of the rib solution. The second algorithm [Figure 2] deconstructs curved forms of greater complexity. The algorithm walks along the surface extracting surface information along horizontal and vertical axes saving surface information resulting in a ribbed structure of slight double curvature. The final algorithm [Figure 3] is expressed as plug-in software for Rhino that deconstructs a design to components for assembly as rib structures. The plug-in also translates geometries to a flatten position for 2D fabrication. The software demonstrates the full scope of the research exploration. Studies published by Dodgson argued that innovation technology (IvT) (Dodgson, Gann, Salter, 2004) helped in solving projects like the Guggenheim in Bilbao, the leaning Tower of Pisa in Italy, and the Millennium Bridge in London. Similarly, the method discussed in this paper will aid in solving physical production problems with complex building forms. References Bentley, P.J. (Ed.). Evolutionary Design by Computers.

title	Integration of Virtual Reality within the Built Environment Curriculum
source	ITCon Vol.11 pp. 311-324
summary	Virtual Reality (VR) technology is still perceived by many as being inaccessible and cost prohibitive with VR applications considered expensive to develop as well as challenging to operate. This paper reflects on current developments in VR technologies and describes an approach adopted for its phased integration into the academic curriculum of built environment students. The process and end results of implementing the integration are discussed and the paper illustrates the challenges of introducing VR, including the acceptance of the technology by academic staff and students, interest from industry, and issues pertaining to model development. It sets out to show that fairly sophisticated VR models can now be created by non-VR specialists using commercially available software and advocates that the implementation of VR will increase alongside industry’s adoption of these tools and the emergence of a new generation of students with VR skills. The study shows that current VR technologies, if integrated appropriately within built environment academic programmes, demonstrate clear promise to provide a foundation for more widespread collaborative working environments.

title	Linking Land Use Modelling and 3D Visualisation - A mission impossible?
source	Van Leeuwen, J.P. and H.J.P. Timmermans (eds.) 2006, Innovations in Design & Decision Support Systems in Architecture and Urban Planning, Dordrecht: Springer, ISBN-10: 1-4020-5059-3, ISBN-13: 978-1-4020-5059-6, p. 85-101
summary	Additional to the traditional land use maps 3D visualisation could provide valuable information for applications in the field of spatial planning, related to ecological and agricultural policy issues. Maps of future land use do not always reveal the appearance of the physical environment (the perceived landscape) as a result of land use changes. This means that 3D visualisations might shed light on other aspects of changed land use, such as expected differences in height or densities of new volume objects, or the compatibility of these changes with particular characteristics of the landscape or urban built environment. The Land Use Scanner model was applied for the Netherlands Environmental Assessment Agency's 'Sustainability Outlook' to explore land use changes, followed by GIS analyses to asses both the development of nature areas and the degree of urbanisation within protected national landscapes. Since it was felt that 3D visualisation could complement the resulting land use maps, the land use model output was coupled to 3D visualisation software in two different ways: 1) through Studio Max software in combination with iconic representation of the concerned land use types and 2) through 3D components of GIS software. However, the use of these techniques on a national scale level for the generation of semi-realistic 3D animations raised a number of conceptual and technical problems. These could be partly ascribed to the particular format and of the Land Use Scanner output. This paper discusses the methods and techniques which have been used to couple the output of the land use model to 3D software, the results of both approaches, and possible solutions for these problems.

title	Developing a Spatial Context-Aware Building Model and System to Construct a Virtual Place
source	Van Leeuwen, J.P. and H.J.P. Timmermans (eds.) 2006, Progress in Design & Decision Support Systems in Architecture and Urban Planning, Eindhoven: Eindhoven University of Technology, ISBN-10: 90-386-1756-9, ISBN-13: 978-90-386-1756-5, p. 343-358
summary	The current notion of space seems to be inappropriate to deal with contemporary and future CAAD applications because it lacks of user and social values. Instead of using a general term called 'space', our approach is to consider the common unit in architectural design process as a place composed of space, user and activity information. Our research focuses on developing a novel intelligent building data model carrying the essence of place. Through our research, the needs of using virtual architectural models among various architectural applications are investigated at first step. Second, key characteristics of spatial information are summarized and systematically classified. The third step is to construct a semantically-rich building data model based on structured floor plan and the semantic location modeling. Then intermediate functions are created providing an interface between the model and future applications. Finally, a prototype system, PlaceMaker, is developed to demonstrate how to apply our building data model to construct virtual architectural models embodying the essences of place.

summary	In Taiwan, the National Science Council (NSC) has launched the “National Digital Archives Program” (NDAP) since 2002. We participated in two projects: “The 3D digital museum of Taiwan city and architecture” and “Digital model database and professional service for Taiwan city and architecture”. The first one attempted to build a virtual museum for Taiwan city and architecture through the past four hundred years. The second one was a value-added project which intended to further apply the digital contents of the previous one. This project was consisted of 3D refined data, digital knowledge database, and architecture professional service. We were responsible for the 3D refined data. As a result, the digital model database included three cities: Hsinchu, Chiayi, and Tainan, as well as sixty-four architecture models. The interactive entertainment platform is an important leisure in our daily life. In general, the interactive entertainment includes five types: arcade game, PC game, on-line game, TV game, and mobile entertainment. This research pays attentions to the arcade game which presents dynamic interactions between machine and users. Following the improvements of design techniques, we have opportunities to experience many arcade games with different purposes, such as drum game, dance game, and fishing simulator. However, we further apply the digital model database to create an interactive entertainment platform for a racing arcade game.

title	Structural Performance Modelling in Architectural Design Education
source	Computing in Architecture / Re-Thinking the Discourse: The Second International Conference of the Arab Society for Computer Aided Architectural Design (ASCAAD 2006), 25-27 April 2006, Sharjah, United Arab Emirates
summary	In architectural education the process of design has evolved with the development of CAD technology. In many design schools throughout the world, the computer has extended its role beyond that of a drafting machine to become a tool for performance modeling. Applications currently used by students test lighting, thermal conditions, and structural validity, to name a few. However the goals in education are not identical to those in practice, and digital modeling can support learning in many ways that are not particularly useful or appropriate in professional practice. In the design of structures there are three fundamental levels of understanding: behavior, form, and performance. Each has its place in design education and uses digital modeling in different forms. This paper describes various pedagogical models that incorporate computer aided drawing and performance modeling in the teaching of structures. Examples of student exercises and projects are discussed.

summary	UrbanLab is a computer system supporting urban and regional design. The papers outlines two leading aspects of this large research project, aimed respectively to make explicit the dynamic of the design in its time and geographic dimensions, and to interactively represent the interplay of some, explicitly, recognised factors, for instance the role of a multitude of different (local) actors in the design process. UrbanLab has been applied to several projects at different scales. We consider the applications to dynamically and interactively generating models of an Alpine valley. The modelling in the spatial and temporal dimensions provided us with the elements to study the evolution over the next twenty years.

summary	The work presented here brings together two core interests that have been developed by the first two authors over recent years. The first is the development of city models for use in a range of applications where different data sets and different levels of detail may be appropriate. The second is the development of low cost systems that can deliver useful tools to help address Computer Aided Architectural Design problems. In addition the involvement of a colleague in Electrical Engineering and Electronics reflects a long standing belief in the benefits of cross-disciplinary and interdisciplinary work between architecture and parallel research fields. The product of the collaboration is a system that can aid in the production of terrain models that, in our case, are particularly important as the base for a city model (Brown et.al, 2005).

summary	The early findings of this research were presented in eCAADe 2005 International Conference, Lisbon primarily to highlight the concept of High Dynamic Range Images (HDRI) when representing architectural spaces in the form of still images. An experiment had been carried out to compare the results between HDRI rendering and ‘conventional’ lighting simulation algorithms namely ray tracing and radiosity. The results were based on static and using the same exposure factors, when capturing HDRI. This project, funded by Intensification Research Priority Area (IRPA) grant continues to present and report HDRI results in a simulation environment. In this paper, we first briefly explain on the concept of real and fake HDRI. Then a comparison experiment is conducted to compare these two methods and discuss the impact and effectiveness of the illumination computation in architectural simulation environment. In order to carry out the experiment, a few models of the architectural scenes were developed. These models were then textured with real photos and manipulated with ‘shaders’, and further rendered using fake and real HDRI techniques. As for the fake HDRI, two methods were developed. The first was using an image as the ambient map and different exposures were created by increasing the value of Hue, V of HSV and saturation. The second involved a series of digital photos with the selection of the brightest and darkest area using Adobe Photoshop to establish the scale of luminosity. A few camera movements were triggered and position for ‘real-time’ rendering simulation. The result of the experiment has shown a significant improvement on the rendering time and quality of the rendering. Finally this paper suggests the selection criteria for choosing real and fake HDRI, and how each technique can be best utilized for architectural representations in a simulation environment.

title	Survey on the Use of Lighting Design Software in Architecture and Interior Design Undergraduate Education
source	International Journal of Architectural Computing vol. 4 - no. 4, pp. 91-108
summary	With the steady development of global illumination algorithms over the past four decades, lighting design software is no longer the domain of a specialist. Easy to use interface, built-in flexibility, reliable calculation models, and compelling visuals has made today's lighting design software useful to architects and interior designers. However, despite these advantages, the use of lighting design software is not widely included in the undergraduate architecture and interior design education. This paper summarizes the results of an online survey of a sample of accredited architecture and interior design schools in the United States conducted to (a) determine the extent of use of lighting design software in teaching and learning lighting at the undergraduate level and (b) to assess design educators' attitude toward their usefulness in design education. This paper discusses directions for the future based on the survey results.

summary	Forty years of development have passed since digital technologies were used in the service of design for the first time but many of the early questions about its usefulness are still open. The beginning [early] period, known as call “analytical”, was founded in a rational and reductionist understanding of the phenomenon, including those related to creative processes. The target was rational optimization for possible solutions around a given problem. Later on, the graphic technologies development meant a huge jump in issues concerning 3D representation of designed objects. A great interest in visualization and “the virtual” then arose: almost everything and any shape, could be modelled and visualized, obtaining representations of space, time, light and matter as never seen before in any field related to imaging. Today these useful technologies are amplified due to the connectivity of the web, stimulating the birth of applications and models which seek to optimize the production processes. However, before of its impact, there is still a question waiting to be answered since the first days of CAD: has all this technology actually allowed the development of better design? The answer doesn’t seem to be obvious, when above all we see ourselves facing the context of a global world that becomes more and more complex. Digital technology is developing very rapidly. Despite this, an equally accelerated improvement in design products is not so clear. The reason for this could be the fact that our practices as designers have not been updated and improved at the same speed as technology. This next Sigradi is about debating how our organizational practices are changing with the digital phenomenon and how the users can positively trigger the potential that lies in these technologies. The hypothesis that underpins this question is the consideration that digital technologies are a unique platform to achieve the necessary integration of knowledge that must feed any contemporary design process. We think that the integration of multidisciplinary knowledge, memories, values and imagination must become the starting point in the production of better design.
