title	The DXI Experience. Ten Years of Design Visualization Developments in an Educational Laboratory Context

summary	Design visualisation is an essential aspect of virtually every form of design enquiry. The effects of potential environmental interventions may be simulated in order to gain the types of insights, which cannot be acquired easily from two-dimensional notations. Three-dimensional representations may be generated for very different reasons. The most direct form of design imaging is traditionally for the benefit of the designer him/herself, in order to test whether the working concepts offer fitting solutions to the complex array of design conditions such as context, programme and feasibility. Alternately, images may be generated for the benefit of communication, in order to offer insights into the expected workings of a particular proposal (possibly including alternatives). This may lead to greater understanding and possibly to reaching consensus amongst different ‘actors’ involved in the design and realisation process. In many cases the results of such visualisation studies contribute to ‘bridging the gap’ between the professionals and other parties involved more indirectly in design decision-making or the appraisal of the proposals. Designers can use distinctly different methods when going about such imaging procedures. Their choices for particular techniques may depend on their familiarity or the availability of certain media devices. Being confronted with new modelling and/or visualisation instruments can stimulate the interest in fresh approaches. In this respect, the design education environment can play an important role in not only teaching ‘proven’ applications to future designers, but also in creating a platform for the active development of innovative approaches to the design visualisation practices: education as a ‘laboratory’ for new insights and potentially a ‘breeding ground’ for the extension of the designer’s instrumentation. This contribution documents the experiences gained in some ten years within an educational application, involving active use of design driven media applications. The emphasis lies on the evolvement of techniques for eye-level imaging, whereby use can be made of different types of models: physical scale models as well as digital, virtual models. Changing attitudes towards dynamic and serial vision are considered, whereby storyboard approaches on the level of integral presentation are considered. By analysing a selection of cases and their underlying approaches an indication is given of the changing attitudes and combinations of multimedia techniques, which offer opportunities to design visualisation and communication.

title	Towards More Effective Use of Building Performance Simulation in Design
source	Van Leeuwen, J.P. and H.J.P. Timmermans (eds.) Developments in Design & Decision Support Systems in Architecture and Urban Planning, Eindhoven: Eindhoven University of Technology, ISBN 90-6814-155-4, p. 291-306
summary	This paper discusses some issues which hinder effective use of building performance simulation in building design, and some approaches towards better and more efficient use of this important but underutilized technology. In particular, the paper discusses the issues of quality assurance, the relative slow software developments and the limited use (usability) of building performance simulation mainly during the final stages of the building design process.

title	Environment – Urban Interface within Urban Growth
source	Van Leeuwen, J.P. and H.J.P. Timmermans (eds.) Developments in Design & Decision Support Systems in Architecture and Urban Planning, Eindhoven: Eindhoven University of Technology, ISBN 90-6814-155-4, p. 49-62
summary	This work presents the synthesis of a model of urban growth dedicated to accomplish simulations of urban spatial dynamics, based on integrated urban and environmental factors and promoting simultaneity among external and internal growth. The city and surrounding environment are captured and modeled in computational ambient, by application of the centrality / potential model (Krafta, 1994 and 1999), with support of graph theory, cellular automata, GIS and geocomputation. The model assumes the city as a field of opportunities for obtaining income, mediated by the space, which is composed of urban and environmental attributes, that work as attractors or as resistances for the urban growth. The space configuration and the distribution of those attributes generate tensions that differentiate qualitatively and quantitatively the space, through the centrality measure (built with the support of graphs techniques), coming to provoke growth in places with larger potential of development (built with the help of techniques of CA – cellular automata). Growths above environmental thresholds are considered problems, generated and overcome in the same process of production of the urban space. Iterations of that process offer a dynamic behaviour to the model, allowing to observe the growth process along the time. The model presents several possibilities: a) urban - natural environment integration; b) internal and external growth integration; c) variety in the scale; d) GIS integration and geocomputation; e) user interface; f) calibration; g) theoretical possibilities; and h) practical possibilities.

summary	The aim of the proposed project is to develop methods for the simulation of space utilisation. Up to now no methods for building performance evaluation are available which involve the occupants of the building. Instead, assumptions are made about people’s movement through space and their responses to the environment. These assumptions are input for important design decisions (e.g. capacity of elevators, width of corridors, escape routing) sophisticated calculations (e.g. cooling and lighting calculations) and simulations (e.g. airflow simulation, evacuation simulation). Reliable data on human movement are very scarce and can be valuable input to research in other research areas. New computer technologies allow for dynamic simulations that will provide insight into the building to be built. The research project builds upon existing methods that need to be tailored and/or extended to apply them to the building domain and to support real-time simulation.

title	Performance Based Planning for High Density Urban Habitation
doi	https://doi.org/10.52842/conf.ecaade.2004.515
source	Architecture in the Network Society [22nd eCAADe Conference Proceedings / ISBN 0-9541183-2-4] Copenhagen (Denmark) 15-18 September 2004, pp. 515-522
summary	In Hong Kong, about 22% of the total territory‘s area can be classified as built-up area and potential development area. Only 6% of this area is allocated to district and local open space for the 6.8 million populations, i.e. 2m2 per person. Sensible planning of the limited area to enhance the livability and environmental quality hence become a challenging issue for quality urban living of the mass population. However, considering the dynamic relationship of the different performance criteria in the hyper-dense urban environment, one needs to assess various environmental criteria to carry out a balanced planning. Meanwhile, effective tools to evaluate and manage the inter-relationship of these criteria, or indexes for integrated issues indication are not readily available that a reasonable planning is not always easy to achieve. In this paper, the „openness ratio“ concept is introduced for open space planning to provide an integrated index for early stage of planning and design. The new index is expected to provide a comprehensive rating system in considering the environmental performance of open area. It helps to highlight the potential problems in planning or site layout and support the integrated thinking of the four key components: visual sensitivity, urban wind, urban noise and solar heat gain. The concept has shown to be feasible on simple massing study which is applicable in the preliminary planning stage.

title	Interactive Space Generation through Play - Exploring Form Creation and the Role of Simulation on the Design Table

summary	In this paper we report on recent developments in ARTHUR: an approach to support complex design and planning decisions for architects together with the simulation of pedestrian movement and the integration of existing CAD tools on the design table. Following a brief introduction, past and current work that has taken a similar approach will be reviewed. Next we describe a scenario that integrates agent-based simulations of pedestrian movement with space creation, and then give an overview of the system before finally discussing findings related to recent user evaluation studies of the system. This paper suggests that the integration of simulated pedestrian movement on the design table, while going through a cycle of reflection-in-action, plays a vital role in exploring possible design solutions and encourages new and different ways of thinking about design problems.

title	A Review of Object Oriented CAD Potential for Building Information Modeling and Life Cycle Management
source	eDesign in Architecture: ASCAAD's First International Conference on Computer Aided Architectural Design, 7-9 December 2004, KFUPM, Saudi Arabia
summary	In many countries, the Architecture/Engineering/Consulting (AEC) industry is characterised by poor performance reflected in project delays and cost overruns. A contributor to the problem is the traditional approach to handling building information and its communication in life cycle management (LCM). Recent developments in Object Oriented Computer Aided Architectural Design (OO CAD) have provided the opportunity for improving building information modelling and its communication for more effective LCM. The aim of the paper is to review the potentials of OO CAD for building information modelling (BIM) and LCM. The paper reviews building information in the life cycle process, identifying the various actors and activities and the need for communication and information flow to support life cycle management. The paper also reviews the concept of OO CAD, highlighting its potential to improve building information and its flow and communication in life cycle management. The paper then goes on to review the potentials and limitations of OO CAD implementation in the AEC industry. The paper concludes by pointing out that the widespread adoption of OO CAD and the anticipated associated improvement in life cycle management will only be encouraged when the building industry is able to agree on a widely acceptable, interoperable standard for encoding building objects.

title	Pedestrian Behaviour Modelling

summary	This paper introduces a study of pedestrian behaviour modelling which incorporates ideas about agent-based systems and the traffic models based on the utility-maximization theory. The aim of this study is to examine the applicable scope of one of the basic assumptions in existing spatial behaviour models; the route with shortest distance maximizes the utility of each pedestrian’s travel. Although shortest-path models have been widely used in the field of Traffic management to predict routing behaviour, there can be seen a lot of erratic behaviour in urban areas, shopping migration behaviour for instance, which can not be explained by them. Thus, it is important to identify other possible influential factors on their utility maximization process in order to develop more explicable models of pedestrian movements. In this study, we implemented a simulation model using the shortest-path model as one of evaluation criteria of Genetic Algorithms (GA) to computationally emulate retail movements of shoppers in a big shopping centre and to test the accuracy of the model by comparison between the routes estimated by the model and actual trajectories of shoppers. This simulation system will be used as a platform for further modelling.

title	Space is the Machine, with a Ghost Inside
source	Van Leeuwen, J.P. and H.J.P. Timmermans (eds.) Developments in Design & Decision Support Systems in Architecture and Urban Planning, Eindhoven: Eindhoven University of Technology, ISBN 90-6814-155-4, p. 157-173
summary	The purpose of this paper is to report efforts towards the construction of a model for urban spatial dynamics simulation, based on multi-agents and space. The underlying idea is to have urban space producers and consumers operating in a two-layer, two-circuit model. The first layer holds urban space and its successive transformations; a second layer contains agents related to space; the first circuit simulates space production, and a second one simulates space consumption. Relationship between layers is represented as objective spatial features that agents are submitted to (the machine) and subjective meanings agents attach to each spatial feature (the ghost). While space works always in the same way, meanings vary according to each agent’s background and context. Relationships between circuits are represented by means of a market game in which producers try to maximize their profits by gambling with their risks, whereas consumers try to foresee the spatial distribution of local externalities that maximizes their utilities and investments. Urban Spatial Features are captured through centrality and land use patterns; every single agent’s action leads to changes in both patterns. Producers’ profit is a function of built form location. Consumers’ local externalities are concerned basically with present and future services. The model iteration is twofold: first it generates and allocates a number of built forms within a previously determined spatial system (a cellular matrix, for example), and second it allocates users to built forms. Population of users have its social profile and growth rate externally determined. Built form allocation is decided on the basis of a combination of profitXrisk perspectives. Users’ locational choice is supported by accessibility to services and present/future neighbourhood profile. Built form allocation works as parameter for users’ locational assessment, whereas users’ choices are used as parameters for developers. The model tends to adjust itself, in terms of quantities and types of built forms to be erected, although through a market lag of some iterations. Allocations are always made through weighted draws, so that mutations (non deterministic allocations) do occur.

title	Ivy: Bringing a Weighted-Mesh Representations to Bear on Generative Architectural Design Applications
doi	https://doi.org/10.52842/conf.acadia.2016.140

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	This paper explains the results of a collaborative research project between Multimedia University (Malaysia) and Innotive Corporation (Korea) to manage, design a multimedia archiving system and visualising knowledge for the students or the users in the Faculty of Creative Multimedia, Multimedia University. This research introduces InnotiveBrowser technology, a high performance multimedia display software that enhances the ability of user to search and discover digital content. The unique result of this method is that the images to be viewed are not limited to available RAM, instead the content utilises the available storage directly from the disk (hard drives). In other words, the larger the size of the hard disk, the greater the number of content information can be stored and displayed. This system is employed with Virtual Reality (VR) techniques particularly imparting viewing technology (pixel-ondemand) and navigation strategy to increase the viewing speed of multimedia information in real-time over the Internet, broadband and even via PDA platforms. This research hopes to set the benchmark for multimedia archiving system that can be applied in other CAD, CAAD or most of the design or production-based teaching and learning environment. The early findings of this research have been patented and this paper will demonstrate the research ideas and explain how we implement and customise the technology and content development in the Faculty of Creative Multimedia, Multimedia University.

title	Surround Digital Audio in Architectural Animation and VR Environment

source	Architecture in the Network Society [22nd eCAADe Conference Proceedings / ISBN 0-9541183-2-4] Copenhagen (Denmark) 15-18 September 2004, pp. 82-88
summary	To stimulate all five senses through a realistic representation, audio plays a significant role. Architectural representation in digital media primarily falls in the area of visualization. Recent developments in simulation of 3d animation, lighting effect, material options and texture quality demonstrate that technology has come to a satisfactory level for representing realistic environments. But, at the same time, designers may not have paid due attention in regards to simulation of quality audio in architectural representation, particularly in 3D animation. “Surround Sound” or technically, the Dolby Digital and DTS technology has been used for entertainment purposes in film and movie production for a long time. As realistic materials and lighting increases the value of reality, sounds and sound effects too can add value to represented virtual reality architectural environments. Surround Sound technology simply delivers different signals from a 360-degree range. The reason beneath this is to break the sense of looking towards a single direction. Ideally, the audio should come from the direction of the visuals on the scene. Synchronization of both visual and Dolby Digital audio can enhance the experiential quality of an audio-visual representation. At the same time, it can break the notion of audio coming from a single direction. This paper suggests and demonstrates the technique of combining surround sound in digital 3D architectural animation for the purpose of enhancing its visual and sensory quality.

title	Knowledge Model for Cultural Analogy in Design and Design Education

summary	Almost every architect uses analogy while designing. The source of inspiration is nature, technology, geometry, etc., besides the influence of the work of other architects. Analogy in architecture has a close relationship with culture as well. Culture is a dynamic occurrence and evolves by the influence of many aspects such as technological, economical, environmental and social. In the process of design, architects built op knowledge from their own experience and designs, but also from the other designers work. Usually, architects develop this quality and ability during the education, and later by trial and error methodwhile practising the design. This is habitually done based on own conscience, intuition and experience.The developments in ICKT (Information, Communication and Knowledge Technology) as a part of broader technological developments and the ongoing globalisation, influences the culture as a dynamic process and therefore the architecture.. It is necessary to make these influences explicit for their embedding in architectural design education of young professionals. This can be achieved by transferring the resulting knowledge to a knowledge model by using intelligent modelling techniques. The operational aspects of design analogies to be implemented in education, research and the daily practice of designing architects need attention. This paper discusses the operational aspects of cultural analogy in design by using an intelligent computational modelling approach.

title	To CAAD or not to CAAD?
source	SIGraDi 2004 - [Proceedings of the 8th Iberoamerican Congress of Digital Graphics] Porte Alegre - Brasil 10-12 november 2004
summary	This paper reports a design experiment with first year.s students in two European countries .It reviews the role that computers can play in the early design stages and considers how far recent developments in commercial software have enabled designers to improve their design performance using CAAD systems. The authors are teaching architectural design in first and forth year in two European countries and are also involved in teaching Computer Aided Architectural Design. The starting point for our experiment was the fact that we realized that most of the students in our faculties still start their design with pen and paper. Although they introduce the computer quite early in the design process now their first design ideas were mainly visualized in sketches. Is this because of the often stated limitations of hard and software or because we start to teach them to sketch when we do design? This paper attempts to address some of the issues and find some answers.

title	Information systems for the design and management of transformation in Dutch educational buildings
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	Following a period of little change, new didactic approaches coupled to social and technological developments have recently triggered several fundamental modifications in Dutch secondary education. These modifications have extensive consequences for the accommodation of secondary education. The majority of existing buildings is quite conventional in spatial terms and is characterized by limited flexibility and transformability. The paper is a description of a modular yet coherent information system that supports decision taking concerning the transformation of existing buildings. The system consists of spatial and topological representation of a building and its brief, as well as a matching system that connects the two.The purpose of the system is to support the management of the building transformation by providing appropriate input to design and decision activities, as well as by accommodating their output. This is achieved by providing a responsive context for the analysis and evaluation of design decisions from the major viewpoints and with respect to primary aspects. Continuity is a major consideration in this context: appropriate information and feedback should be available throughout the design and construction process but also after completion (in anticipation of further transformations, as well as for monitoring building performance).

title	Urbamedia - Development of an urban database of fragments of some Argentinian and Latin-American cities using digital technology
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	The proposal of "Urbamedia" is to undertake the development of 3D virtual and interactive models of historical areas of Latin-American cities. The selected zone is the "Mayo Avenue" including the "Mayo Square", an historical place of the city of Buenos Aires, Argentina; this project is financed by the National Agency of Scientific and Technological Development of Argentina and the University of Buenos Aires.We are presenting the first experimental model of the "Mayo Square" that has been developed at ABACUS, Department of Architecture & Building Aids Computer Unit, University of Strathclyde UK. combined with a system analysis of urban activities using the “Atlas.ti” CAQDAS software.This particular use of the “Atlas.ti” software is under experimental applications to this type of urban analysis procedures; allowed us the possibility to analysed a set of activities by means of graph theory as result of a series of interviews to the people working in the area. We are also looking to include historical areas of three cities: Mar del Plata, Rosario and Santa Fe (Argentina) and eventually other cities from Latin América as Rio de Janeiro and Habana.Due that ABACUS has a strong experience in city modelling plus the powerful software and hardware used there, we must develop a VRML customized menu to be adapted to our low cost PC equipment. The 3D model will be used mainly in urban design simulation procedures and the idea is to extend to other type of simulations of the environmental parameters.

title	Using a Spatial Microsimulation Decision Support System for Policy Scenario Analysis
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. 177-191
summary	This paper discusses the potential of a spatial microsimulation-based decision support system for policy analysis. The system can be used to describe current conditions and issues in neighbourhoods, predict future trends in the composition and health of neighbourhoods and conduct modelling and predictive analysis to measure the likely impact of policy interventions at the local level. A large dynamic spatial micro-simulation model is being constructed for the population of Leeds (approximately 715,000 individuals) based on spatial microsimulation techniques in conjunction with a range of data, including 2001 Census data for Output Areas and sample data from the British Household Panel Survey. The project has three main aims as follows: (i) to develop a static microsimulation model to describe current conditions in Leeds; (ii) to enable the performance of ‘What if?’ analysis on a range of policy scenarios; and (iii) to develop a dynamic microsimulation model to predict future conditions in Leeds under different policy scenarios. The paper reports progress in meeting the above aims and outlines the associated difficulties and data issues. One of the significant advantages of the spatial microsimulation approach adopted by this project is that it enables the user to query any combination of variables that is deemed desirable for policy analysis. The paper will illustrate the software tool being developed in the context of this project that is capable of carrying out queries of this type and of mapping their results. The decision support tool is being developed to support policy-makers concerned with urban regeneration and neighbourhood renewal.

summary	This paper presents a study in digital design and manufacturing of shells, which are material-efficient systems that generate their load-bearing capacity through curvature. Their complex shapes are challenging to build, and the few current shell projects employ the same shape repetitively in order to reduce the cost of concrete formwork. Can digital design and manufacturing technology make these systems suitable for the needs of the 21st century? The research developed new digitally-driven fabrication processes for Wood-Foam Sandwich Shells and Ferrocement-Concrete Sandwich Shells. These are partially pre-fabricated in order to allow for the application of Computer-Numerically Controlled (CNC) technology. Sandwich systems offer advantages for the digitally-enabled construction of shells, while at the same time improving their structural and thermal performance. The research defines design and manufacturing processes that reduce the need for repetition in order to save costs. Wood-Foam Sandwich shells are made by laminating wood-strips over a CNC-milled foam mold that eventually becomes the structural sandwich core. For Ferrocement-Concrete sandwich shells, a two-stage process is presented: pre-fabricated ferrocement panels become the permanent formwork for a cast-in-place concrete shell. The design and engineering process is facilitated through the use of parametric solid modeling environments. Modeling macros and integrated Finite-Element Analysis tools streamline the design process. Accuracy in fabrication is maintained by using CNC techniques for the majority of the shaping processes. The digital design and manufacturing parameters for each process are verified through design and fabrication studies that include prototypes, mockups and physical scale models.

summary	Highway seems to be more an issue of traffic planning than of urban design. But the highway can be a very important factor for the modern city pattern. Highways shape the spatial form of the fractal city. The modern highway can define new cores outside and “interior edges” within the city. Seen as a planning tool, highways are the great neglected opportunity in city and regional design. The 1st Architecture Biennial, 1ab, taking place from May 2003 to July 2003 in Rotterdam, explores the creative potentials of modern highways worldwide. An international research team discovered the spatial functions of highways in modern agglomerations. This lecture will give an overview of the results of the worldwide analyses and the design projects that had been undertaken. Both authors are members of the German research team. The German team examined the A 42 running through the Ruhrgebiet, a former coal and steal area in western Germany. The Ruhr Area is converting from an industrially orientated region to an agglomeration of high technology and science. But the regional image remains the same due to the fact that the changes cannot be seen, neither physically, nor from the road. Here, the highway could be used as a catalyst supporting and structuring the spatial changes to make them more legible for the people of Rhine-Ruhr. The nature becomes the most important tool of highway design. Landscape forms a linkage between the different cities of the region. Together with the A 40 and other local highways the region becomes the most important (and largest) public space of the new Rhine-Ruhr. The highway seen as a work of urban art can be designed only from the perspective of the driving car.

title	An Energy Centric Approach to Architecture: Abstracting the material to co-rationalize design and performance
doi	https://doi.org/10.52842/conf.acadia.2008.072
source	Silicon + Skin: Biological Processes and Computation, [Proceedings of the 28th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) / ISBN 978-0-9789463-4-0] Minneapolis 16-19 October 2008, 72-81
summary	This paper begins by exploring matter as an aggregated system of energy transactions and modulations. With this in mind, it examines the notion of energy driven form finding as a design methodology that can simultaneously negotiate physical, environmental and fabrication considerations. The digital workspace enables this notion of form finding to re-establish itself in the world of architecture through a range of analytic tools that algorithmically encode real world physics. Simulating the spatial and energetic characteristics of reality enables virtual “form generation models that recognize the laws of physics and are able to create ‘minimum’ surfaces for compression, bending [and] tension” (Cook 2004). The language of energy, common in engineering and materials science, enables a renewed trans-disciplinary dialogue that addresses significant historic disjunctions such as the professional divide between architects and engineers. Design becomes a science of exploring abstracted energy states to discover a suitable resonance with which to tune the built environment. ¶ A case study of one particular method of energy driven form finding is presented. Bi-directional Evolutionary Structural Optimization (BESO) is a generative engineering technique developed at RMIT University. It appropriates natural growth strategies to determine optimum forms that respond to structural criteria by reorganizing their topology. This dynamic topology response enables structural optimization to become an integrated component of design exploration. A sequence of investigations illustrates the flexibility and trans-disciplinary benefits of this approach. Using BESO as a tool for design rather than purely for structural optimization fuses the creative approach of the architect with the pragmatic approach of the engineer, enabling outcomes that neither profession could develop in isolation. The BESO case study alludes to future design processes that will facilitate a coherent unfolding of design logic comparable to morphogenesis.
