title	Emerging Technololgy – Dilemma and Opportunities in Housing
source	CAADRIA 2007 [Proceedings of the 12th International Conference on Computer Aided Architectural Design Research in Asia] Nanjing (China) 19-21 April 2007

summary	Digital Technology has transformed industrial manufacturing and production; and an array of Industrial Design products provide increasing comfort and benefit to millions of global citizens via ergonomic and mass production/customization strategies. Yet, housing needs of a rapidly growing global population are rarely affected by digital technology. Shifts in societal demographics, from rural to urban city centres, and concurrently Global Warming and ecological changes are exacerbating the world housing situation. Millions are homeless, live in inadequate shelter, or as in the US Manufactured Housing (MH) market, live in nondurable poor quality “manufactured” houses that are detrimental to health, at best, or during extreme weather events, suffer catastrophic damages often resulting in death to occupants. Nevertheless, housing concepts and related living units have benefited very little when compared to architecture’s related manufacturing industries counter-parts (i.e. automotive, aerospace, marine industries, etc). While Technology has vividly expanded the shape language of architecture (i.e. Free-Form-Design), some may argue that Free-Form- Design buildings generally have beauty that is only “skin deep” and typically focus on providing signature statements for both the designer and elite clientele. In this paper, we will briefly review the role of the architect in the US Manufactured Housing industry; additionally, we will identify the major problems that plaque the US Manufactured Housing Industry. Further, we will review how architects and Industrial Designers use technology in their respective fields and draw larger designmanufacture principals for issues of global housing. Our findings and analysis suggest that an Industrial Design approach, applied in architecture for mass housing, offers a means of improving the architect’s role and technology in manufactured housing for the masses.

title	Mindful Spaces: Computational Geometry and the Conceptual Spaces in which Designers Operate
source	International Journal of Architectural Computing vol. 5 - no. 4, pp. 611-624
summary	Combinatorial computational geometry, while dealing with geometric objects as discrete entities, provides the means both to analyse and to construct relationships between these objects and relate them to other non-geometrical entities. This paper explores some ways in which this may be used in design through a review of six, one-semester-long design explorations by undergraduate and postgraduate students in the Flexible Modeling for Design and Prototyping course between 2004 and 2007. The course focuses on using computational geometry firstly to construct topologically defined design models based on graphs of relationships between objects (parametric design,) and concurrently to output physical prototypes from these "flexible models"(an application of numerical computational geometry). It supports students to make early design explorations. Many have built flexible models to explore design iterations for a static spatial outcome. Some have built models of real time responsive dynamic systems. In this educational context, computational geometry has enabled a range of design iterations that would have been challenging to uncover through physical analogue means alone. It has, perhaps more significantly, extended the students' own concept of the space in which they design.

title	Preservation of Architectural Heritage Through 3D Digitization
source	International Journal of Architectural Computing vol. 5 - no. 2, pp. 222-237
summary	Continuity and relation to the past are inherent in human nature. The remains of the past constitute culture and cultural heritage. Preservation and dissemination of cultural heritage appear to be, nowadays, a universal priority. Historic/architectural monuments are among the most significant categories of cultural heritage and their 3D digitization appears to be a chief way towards that direction. 3D digitization of architectural heritage is a very specific problem in the digitization domain. Since size, budget and applicability are some of the most important factors in choosing an appropriate digitization method, and since there is not an all-in-one solution in digitization, this problem cannot be always addressed by using one technique. In this paper we review methods that are available for 3D digitization of architectural heritage and we present two case studies of real-world digitization projects involving monuments and urban areas.

title	Visual impact assessment (VIA): A review on theoretical frameworks for urban streetscape
source	Em‘body’ing Virtual Architecture: The Third International Conference of the Arab Society for Computer Aided Architectural Design (ASCAAD 2007), 28-30 November 2007, Alexandria, Egypt, pp. 87-94
summary	This paper reviews several theoretical frameworks of visual analysis used in computer-based Visual Impact Assessment (VIA) for design decisions in architecture, urban landscape and urban planning. The discussion will focus on the underlying issues of preferences and predictions between designer and lay-public, methodologies of visual analysis, and computing media technologies due to fact that these components primarily contribute towards the result of VIA. Two different sets of visual analysis (i.e. designer’s and layman’s points of view) are presented based on Sanoff’s (1991) arguments that lay-public preferences are always become a second opinion compared to the judgments by designers. These theories will then be developed and used in the VIA experiments to understand the impact of the visuals in different media for viewers’ understanding. This paper concludes with a discussion and suggestion of analysis framework to be used for the visual experiments.

title	Multi-touch - the future of design interaction
source	Computer Aided Architectural Design Futures 2011 [Proceedings of the 14th International Conference on Computer Aided Architectural Design Futures / ISBN 9782874561429] Liege (Belgium) 4-8 July 2011, pp. 557-572.
summary	The next major revolution for design is to bring the natural user interaction into design activities. Graphical User Interfaces (GUI) brought a new approach that was more effective compared to their conventional predecessors. In recent years, Natural User Interfaces (NUI) have advanced user experiences and multi-touch and gesture technologies provide new opportunities for a variety of potential uses in design. Much attention has been paid to leverage in the design of interactive interfaces. The mouse input and desktop screen metaphors limit the information sharing for multiple users and also delayed the direct interaction for communication between each other. This paper proposes the innovative method by integrating game engine ‘Unity3D’ with multi-touch tangible interfaces. Unity3D provides a game development tool as part of its application package that has been designed to let users to focus on creating new games. However, it does not limit the usage of area to design additional game scenarios since the benefits of Unity3D is allowing users to build 3D environments with its customizable and easy to use editor, graphical pipelines to openGL (http://unity3d.com/, 2010 ). It creates Virtual Reality (VR) environments which can simulates places in the real world, as well as the virtual environments helping architects and designers to vividly represent their design concepts through 3D visualizations, and interactive media installations in a detailed multi-sensory experience. Stereoscopic displays advanced their spatial ability while solving issues to design e.g. urban spaces. The paper presents how a multi-touch tabletop can be used for these design collaboration and communication tasks. By using natural gestures, designers can now communicate and share their ideas by manipulating the same reference simultaneously using their own input simultaneously. Further studies showed that 3Dl forms are perceived and understood more readily through haptic and proprioceptive perception of tangible representations than through visual representation alone (Gillet et al, 2005). Based on the authors’ framework presented at the last CAADFutures, the benefits of integrating 3D visualization and tactile sensory can be illustrated in this platform (Chen and Wang, 2009), For instance, more than one designer can manipulate the 3D geometry objects on tabletop directly and can communicate successfully their ideas freely without having to waiting for the next person response. It made the work more effective which increases the overall efficiency. Designers can also collect the real-time data by any change they make instantly. The possibilities of Uniy3D make designing very flexible and fun, it is deeply engaging and expressive. Furthermore, the unity3D is revolutionizing the game development industry, its breakthrough development platform for creating highly interactive 3D content on the web (http://unity3d.com/ , 2010) or similar to the interface of modern multimedia devices such as the iPhone, therefore it allows the designers to work remotely in a collaborative way to integrate the design process by using the individual mobile devices while interacting design in a common platform. In design activities, people create an external representation of a domain, often of their own ideas and understanding. This platform helps learners to make their ideas concrete and explicit, and once externalized, subsequently they reflect upon their work how well it sits the real situation. The paper demonstrates how this tabletop innovatively replaces the typical desktop metaphor. In summary, the paper addresses two major issues through samples of collaborative design: firstly presenting aspects of learners’ interactions with physical objects, whereby tangible interfaces enables them constructing expressive representations passively (Marshall, 2007), while focussing on other tasks; and secondly showing how this novel design tool allows designers to actively create constructions that might not be possible with conventional media.

doi	https://doi.org/10.52842/conf.ecaade.2007.335
summary	This paper sets out an approach to urban modelling derived from early work with cellular automata and agglomeration models. In these cases the models are an example of distributed representation, where the rules built in to the model are replicated in all the discrete components of the model be they cells or agents. This is the classic AI. / AL paradigm of emergent systems. The paper describes the main structure of the models, and presents examples of the use of this modelling process in design education, pointing out the way dynamic models allow mapping on to interesting speculations about the dynamic of the city, and its social systems. The paper ends with a report on the use of such models as a design decision support system and how they will be used in planned work in master planning in the London Thames gateway area under the UK govt. sustainable communities initiative.

title	Digital Masterplanning: Computing Urban Design
source	In Urban Design and Planning: Institution of Civil Engineers, Thomas Telford Publishers, ahead-of-print
summary	The digital revolution has finally reached urban design as one of the last design communities not very familiar with computing. This is despite the city and geography being the natural fields for systems analogy and digital models of mathematical and statistical simulation were developed in the 60s and 70s for urban planning, much before industrial or architectural design. The recent arrival of urban design simulations is however not as innovative and radical as their 50 year old counterparts since they use computing solely for policy visualization, quantity evaluation or pattern generation. The Computational Design and Research Group [CDR] at Aedas\|R&D started in 2007 to develop an open platform of lightweight applications – Digital Masterplanning – in collaboration with partners from academia and industry to provide methods for urban design, based on computational methods called meta-heuristic algorithms. An attempt to encode empirical knowledge and design assumptions into simulations is described where designers can assemble the resulting applications according to scales and brief into custom workflows.

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	Meta-Cognitive Mappings: Growing Neural Networks for Generative Urbanism
source	Generative Arts conference, Milan, 2007
summary	This paper examines the use of dynamic learning systems and adaptive topologies within neural networks models, and their implications as a tool for architectural mappings. The principal investigation is the ability of such systems to identify/ map/ model/ represent flows within dynamic data sets and identify topological relationships between these flows. A growing neural network [GNN] model is proposed, able to map dynamic data inputs over time. It is based on Kohonen’s early self-organising feature maps [SOM] and takes as its starting point previous work by CECA with neural networks in an architectural context, as well as other examples of neural gases, and GNNs, in order to develop a model capable of ‘autopoietic’ behaviour and ‘meta – learning’. The principal investigation is the ability of such a system to identify/ map/ model/ represent flows within dynamic data sets and identify topological relationships between these flows. As a case study, the proposed neural network model has been used to map ‘urban territory’, as part of an on going architectural research project, based in North London. The project takes the notion of ‘urban territories’ rather than ‘urban space’ as the field for interrogation, as a description of temporal spatial occupation space, rather than spatial physical permanence. Furthermore, the GNN may be used to identify the relationships between unused and vacant sites along the street. In this way, the GNN may become a means of proposing architectural interventions for these spaces, so that the territories of those that occupy it and the negotiations between them are not lost.

title	The Creation of Urban Form: A Normative Approach to Modelling
source	CAADRIA 2007 [Proceedings of the 12th International Conference on Computer Aided Architectural Design Research in Asia] Nanjing (China) 19-21 April 2007
doi	https://doi.org/10.52842/conf.caadria.2007.x.t8k
summary	The aim of this research project is to develop a methodological process that allows the designer to assemble and create various scenarios representing an urban environment through the utilization of economical computer based methods. During the last decade different techniques have been developed to address the needs of visualisation of urban areas many being based on photographic and photogrammetric systems. The demand for 3-D urban models continues to grow and although new technologies have undoubtedly reduced the time needed for the construction of a 3D model, there are still some remaining problems related to data quality and the level of the dimensional accuracy. On the basis that these problems are primarily related to software and hardware constraints and in conjunction with the fact that the richness and complexity of an urban space is difficult to represent in a 3D context, there is a growing interest in the modelling of the urban fabric which is not dependant on heavily capitalised technology for its data. The core principle of the current research project is summarised in the process of deploying a mechanism, which will allow the visualisation of urban form without loosing its quality and architectural characterisation. This technique suggests that a selection of various building types can be collected and described by their architectural elements, textures, scale and dimensions. From each group of buildings a library of fragmented architectural components can be then derived. The accomplishment of this methodology is the formulation of a 'grammar' comprised of a characteristic ‘syntax’ and its associated ‘vocabulary’. Therefore the expected outcome of this research is an approach that would allow the designer to create easily and quickly not only any desired building but additionally any imaginary cityscape.

title	Spatial Simulations with Cognitive and Design Agents
source	International Journal of Architectural Computing vol. 5 - no. 1, pp. 100-114
summary	Agent based design systems could provide useful decision help for architects working on spatial planning tasks that involve large number of actors or deal with complex urban situations. These systems are especially helpful in bridging the gap between concrete design proposals and high-level design abstractions such as frequency and flow diagrams. Every attempt to use computational design agents in the planning process will automatically raise many fundamental issues about spatial perception and representation of the environment. The paper discusses these issues in the light of some recent agent based simulations. Two case studies are presented in order to demonstrate different uses of computational agents in urban design. The first study shows how a simple agent-based design system placed in an urban context becomes a creative production tool. The second one reveals analytical capabilities of an agent system in urban environments.

title	Rethinking Parameters in Urban Design
source	International Journal of Architectural Computing vol. 5 - no. 1, pp. 84-98
summary	This paper describes the unique coupling of an architectural urban design studio with an in-depth digital media course for the purpose of exploring new avenues of architectural expression, urban form-finding, and communication through the exploration of urban parameters. By merging descriptive parameters of urban situations with digital parametric tools, the understanding of urban design processes was enhanced by the possibility to perceive and comprehend larger problems of spatial urban experiences. The paper discusses how variables, goals, and outcomes of this urban design studio, as well as its integration with digital parametric design, allowed the participants to create an innovative urban design language. It reviews the implications for design education, as well as for the understanding and communication of complex urban designs that are responsive to a variety of parameters. This work lie sin the tradition of artists who push media to explore new interpretations of both the media themselves and of their artwork as much as it does of the use of parametric systems as technological tools.

summary	Energy demand is a major concern for the future of European Cities. Resource availability and costs, climate change, and their consequences are directly related with the energy consumption in our cities. In 2007 already more than half of the world population live in cities, and cities are the main consumers of energy. The model presented in this paper explores the possibility of estimate the demand of end energy (heat and power) by simulating with a cellular automaton land use changes in a German region, in this case, Stuttgart Metropolitan Region. Several approaches deal with problems due to data availability, non-spatial information sources, aggregation levels, quality and consistence of data, among others. This case study shows that a non-deterministic simulation model of energy demand related to urban growth is already feasible, with several constraints. Otherwise, the energy demand calculations differ in great manner depending on consumption sectors (residential, commercial, industrial, transport) and all these calculation models should be further improved. Software and hardware constraints have been as well identified, and stressed in the conclusions.

title	Fascination google earth – use in urban and landscape design
source	Em‘body’ing Virtual Architecture: The Third International Conference of the Arab Society for Computer Aided Architectural Design (ASCAAD 2007), 28-30 November 2007, Alexandria, Egypt, pp. 141-148
summary	Virtual 3D-City-and Architecture models, Virtual Globe systems like NASA World Wind and Google Earth as well as new attempts of immersive technologies become more important, not only among experts in spatial planning, but also many private users are interested in these new tools. These developments cause powerful impacts in the general social, cultural and everyday life. Given the dynamic development of Google Earth, the discussion about the representation and the use of geodata for a wide user group - beyond the planning disciplines - reaches new heights. According to expert's opinion, Google Earth with its computer language KML (Keyhole Markup Language) becomes a 3D-GIS-Standard [Rush in 2006]. By the easy and quick representation of three-dimensional (city) structures and single buildings, Google Earth will significantly influence all groups of society. User groups which have not been acquainted with geodata or highly specified and complex GIS-Systems [Dworschak in 2006], discover that working with this data by using Google Earth is great fun. They recognize, that with the help of generally understandable and easily recognizable visualisation of these data, mediation of knowledge becomes very easy. In addition, it is acknowledged that geodata has great potential to add value, in disciplines such as the academics, the financial sector or personal use.

title	Readiness for the Use of Technology for effective learning via the vds: Case of the United Arab Emirates
source	Em‘body’ing Virtual Architecture: The Third International Conference of the Arab Society for Computer Aided Architectural Design (ASCAAD 2007), 28-30 November 2007, Alexandria, Egypt, pp. 439-456
summary	Review of the literature indicated that today’s knowledge-driven economy demands a workforce equipped with complex skills and attitudes such as problem solving, meta-cognitive skills, critical thinking and lifelong learning. Such skills can be acquired if learning and teaching are guided by the constructivist and cognitive learning theories. In particular, the constructivist approach emphasises effective learning processes based on learning by doing and collaboration. This approach is congruent with use of technologies, such as Virtual Design Studio (VDS), for the purpose of architecture education in design courses, but such use is lacking in the United Arab Emirates (UAE). It is thus important to assess the extent to which the constructivist and cognitive theories are implemented in teaching design courses in the Architecture schools of the UAE. It is also important to assess the effectiveness of employing technology in general and VDS in particular in implementing these theories. The author intends to study the relationship between effective learning on one hand and using VDS in implementing the constructivist and cognitive approaches on the other hand. Thus, the author conducted a preliminary study to gain a basic understanding of the difficulties, approaches, attitudes, perceptions, and motivation related to the learning of design in architecture schools in the UAE. Second, the investigation was designed to assess the extent to which the students would be interested in the use of sophisticated technology in the teaching and learning environment in the UAE architecture education schools in order to achieve effective learning. The study has been conducted in the United Arab Emirates University (UAEU). Methodology used for this was the focus group method. In addition to the focus group interviews with the UAEU students, unstructured individual interviews with lecturers from UAEU and the American University of Sharjah (AUS) have been carried out. Data analysis showed that students were not satisfied with the current teaching methods based on traditional lectures. It was concluded that students were ready to practice effective learning of design via the intermarriage of VDS and the constructivist and cognitive approaches. An ambiguity that remained was whether students were ready for assessment methods which are consistent with the constructivist approach.

title	Management system for a Virtual Cooperative Project

doi	https://doi.org/10.52842/conf.ecaade.2007.125
summary	The paper presents on-going research aimed at the support of the management of building projects and the aid cooperative design. Today, The use of systems adapted to the cooperative design assistance for the building domain is complex. This results from the complexity of the cooperative work (difficulties in tracking actor’s work, lack of most of the required information, coordination problems, implicit nature of most of the construction activities etc.) The paper will briefly review two data exchanging modes that we had defined. After, on the basis of this concept of cooperative design we describe a new model of a virtual environment aimed to takes into account the relational organization of the project and the semantic meaning of works. This research represents a new approach because it not based on management of documents but on all data relative to works. Finally, we use this new model for defining a design-aided tool, to deduce advantages and limits of the “Virtual Cooperative Project”. This system lets geographically dispersed project actors model the project context of a building. More specifically, it allows interpreting, using and exchanging project works in a centralized virtual environment during the building life cycle. This system uses IFC objects which associate in the same model the semantic and the 3D representation of building works.

summary	This paper presents an experience of collective digital fabrication and parametric modeling of furniture made with recycled plastic waste, inspired by natural elements of the Brazilian northeast. In addition to conventional joinery techniques, we highlight the technologies of rapid prototyping (PR) and digital fabrication (FD) (Volpato, 2007, Pupo, 2008; Pupo, 2009); as tools that promote a paradigm shift, both in the design process and in production and materialization (Kolarevic, 2005), allowing recycled plastic to have new applications. We started with a brief review of digital fabrication processes in Brazil, emphasizing collaboration in design and execution. Then, we contain the recycling of plastic and the need for actions for its best destination. Finally, we present a sustainable and collaborative design experience: the modeling and digital fabrication of furniture, entirely produced from recycled plastic, called “Banco Cabaça”.

title	BIM as a Viable Collaborative Working Tool: A Case Study

summary	For the majority of design practices in the construction industry the use of CAD systems have been used to merely automate hand drafting (Cohen 2003). This is the traditional way of working that has changed very little since the introduction of commercial CAD systems. These practices as means of communication are being replaced by a virtual building model environment which encapsulates all of the information for an entire construction project and thereby enables computer-supported co-operative working practices. (Newton 2003) This study aims to determine whether Building Information Modelling (BIM) can, and whether it will, replace traditional communication media as the standard in the industry for computersupported co-operative working practices in the Architecture Engineering and construction (AEC) sector. The bulk of the research comprises an extensive literature review looking at the principal reasons behind the development of BIM, the potential advantages and drawbacks of the technology, and the barriers and obstacles which inhibit its adoption as a means of computer-supported co-operative working. The findings of the study have been validated and analysed against current practice in the field through a live case study analysis of the on-going Heathrow airport Terminal 5 Project in London (UK). The Terminal 5 case study demonstrates that present software tools, although usable, still present significant implicit technical constraints to wider implementation among Small and Medium Enterprises (SMEs). The case study has also shown that in practice, the success of BIM depends just as much on the working practices and ethos of participants in the project chain as it does on the capabilities of the software itself, in particular the willingness of practitioners to change traditional working practices. The case study has shown that the present investment, in terms of time, cost, and effort required to implementing the technology means that BIM is unlikely to be adopted on small simple projects where conventional CAD is still adequate. It also highlighted that BIM tools currently available are not yet adequately developed to satisfy the requirements of the many procurement and especially contractual arrangements which presently exist and many firms will be frightened off by the unresolved legal issues which may arise from implementing BIM in their practices.

title	Applying generative modeling procedure to explore architectural forms

summary	Computer generated 3D forms using generative procedures have matured in the last decade and now considered as a tangible approach for realizing architectural design ideas. As fascinating as the approach might be, it is still lacking actual application in the early architectural design process. There are many reasons for this, among them: it has many implications over the architectural design process mainly the practicality of design during the conceptual design stage; it is cumbersome to develop construction drawings for complex architectural forms; and the necessity for producing conceptual designs quickly in less time as design requirements and decisions are constantly being changed. This paper initially reports on a practical development of a computer program which generates architectural massing designs based on integrating forms generation technique in a design scheme. The influence for this development was inspired by Spirolaterals technique used in generating complex 3D architectural forms that are based on parametric shape configuration. The development has three goals: to review the principles for constructing generative forms in the conceptual design stage using simple CAD tools, to assist in the production of design schemes based on a few basic shapes and rules, and to explore 3D forms finding and generation without the need to write a complicated computer program that are difficult to produce by hand. The development resulted in generating an interesting number of 3D compositions. The author applied this technique to experiment during the production of a design scheme. The paper hence describes the current development of ArchiGen tool to produces generative 3D forms utilizing ArchiCAD © GDL programming language. The tool is embedded within ArchiCAD for generating 3D shapes. One of the main features of this implementation is that users are able to sketch 2D shapes and the tool will deform its three dimensional generation. Moreover, the user being able to abstract the architectural character from the resulting complex 3D shapes. This development extends current related work by allowing the designer to load shapes into ArchiGen which acts as vocabulary of shapes for a design scheme constraints. It is intended from this work to inspire future work focusing on using generative tools in the early conceptual design stages.
