title	Generative Systems Based on Animation Tools: Shaping Alternatives to Structure and Form in Architectural Design
source	Predicting the Future [25th eCAADe Conference Proceedings / ISBN 978-0-9541183-6-5] Frankfurt am Main (Germany) 26-29 September 2007, pp. 245-251

summary	Our system is based on computer animation tools, employed in the context of architectural synthesis. The pipeline of the tool consists of “time” and space design constraints of boundaries / objects affecting a given architectural design, with an output of alternative designs. The alternative designs vary from the original according to their temporal and/or spatial distance from the original object on the animation time-line. Specific tools [shape driven curves, speed and time-line functions,parent child relationships, boolean operations, arrays, lattices etc.] empower the designer with the ability to transform his original idea in almost every way the designer likes in a completely visual, interactive and straightforward manner. The solutions sets change according to time, speed, location, configuration of the objects and/or the constraints and rules the designer/user configures. Previous work on our tool stemmed from the rule based structure of shape grammars, but has evolved to a tool where the designer does not have to define a rule set beforehand but does so as his idea evolves during design. The animation tools used are form independent (that is the designer can use any two- or- three-dimensional form) and can represent structural decisions in a given design. The independence from form makes the tool suitable for almost every kind of architectural design, be it experimental, real or conventional while the ability to represent structural decisions and relations of parts in a design implicitly help the designer/user acquire a clear picture of each design and solution set. Finally the possibility of a structured graph representing each solution is discussed, where the designer can evaluate the merit of an individual solution in terms of conforming to the initial core idea or where alternative spatial configurations evolve in a different structure from the original design.

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.

title	Generative Systems Based on Animation Tools: Structure and Form of Core Ideas in Architectural Design
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.k1h
summary	The goal of the research described in this paper is the formulation of a generative system for architectural design, where a structured core architectural idea is the input and alternatives to that idea are the output. Specifically we present a production pipeline of architectural / spatial configurations using the context of animation and time based design tools. Our model consists of “time” and space design constraints of boundaries / objects affecting a given architectural design, thus producing an alternative solution for every timeframe of the animation cycle. Initially the designer shapes an idea using animation software tools, where each tool is actually a constraint or a grammar rule defined informally by the user/designer. The influence of the tools can vary according to time, speed, location, configuration of the object and/or the constraint itself. In some of these animations the designer has the ability to sidestep partially the issue of emergence by providing specific key - frames for the solution to follow. The use of animation tools [shape driven curves, speed and time-line functions, parent child relationships] in the shape generation of our model empowers the user/designer to configure whole sets of shapes and designs interactively and without the need to define every solution independently. Simultaneously, a different, time-focused view of our model describes its use on designs that develop different configurations over time. Thus a duality of our model is established : the animated schema may be either a sum or a family of various designs or the animated time-line may represent a single design which changes over time. Finally the possibility of a structured graph representing each solution is discussed, where the designer can evaluate the merit of an individual solution in terms of conforming to the initial core idea or where alternative spatial configurations evolve in a different structure from the original design.

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	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	SecondLife: A Computer-Mediated Tool for Distance-Learning in Architecture Education?
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. 17-34
summary	Despite the importance of distance learning for its ability to reach a wide audience, easiness to access materials, and its lower cost compared to traditional learning, architecture education has not been well served by distance education. This is because it has a higher level of learning objectives, it is taught by coaching methodologies, and involves nonverbal forms of communication. One of the most common learning methods used in the design studio is the Criticism/Critique, which is a graphic and oral type of communication between the tutor and the students. In this investigation, Second Life, a massive multi-user online virtual environment that offers three-dimensional spatial capabilities via Avatars impersonation, is used as a computer-mediated tool for text and graphic-based communication in a distance learning situation. The study describes a demonstration experiment where students had to communicate with their tutor, display and describe their projects at a distance, in a purposely designed criticism space in SecondLife. The main objective of this paper is to observe and document the effects and the use of SecondLife virtual environment as an online 3D graphical-based tool of computer-mediated communication in distance learning in architecture education. The study also answers some questions: How well did the students use the tools of the medium provide? Was there a sense of personal communication and realism gained through using Avatars in the virtual environment? Did SecondLife provide a successful means of communication for a graphic-based context? And what are the students’ opinions about the learning environment? Using multiple methods of data collection, mainly based on an electronic observation of the experiment, questioning the participants before and after the experiment, and the analysis of the chat transcripts, the study presents descriptive results of the experiment, and discusses its main features. Proposals for modifications are made for future replications.

title	Mediating between Architectural Design Ideation and Development through Digital Technology

summary	Negroponte (Negroponte 1969) described how the creative thinking of a designer can become affected by the ‘machine’ urging the designer to draw a distinction between ‘heuristics of form’ and ‘heuristics of method’. This ensured that by taking advantage of digital technology a symbiotic relationship was maintained between both of these. To date architects have investigated digital tools for generating form and imagery with increasing success, but have arguably fallen short of using those tools for advancing their design methods. The research presented here explores questions not solely focusing on the use of the tools, but on heuristic methods of the profession, to examine the interconnectiveness of the design method and the tool in a symbiotic fashion; to examine the nature of creativity. This paper is taking a critical standpoint about the place of digital tools in an architect’s method in the pursuit of poetic architecture and, in particular, its representation, to enable speculation, as opposed to prediction, of ideas in the design process from the early phases. The issue is discussed through the findings of my doctoral research case studies that have proved germane to my particular enquiry, that is, digital mediationbetween design ideation and design development.

title	Understanding Pre-Construction Simulation Activities to Adapt Visualization in 4D CAD Collaborative Tools
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. 477-492.
summary	Increasing productivity and efficiency is an important issue in the AEC field. This area is mainly characterized by fragmentation, heterogeneous teams with low lifetimes and many uncertainties. 4D CAD is one of the greatest innovations in recent years. It consists in linking a 3D model of the building with the works planning in order to simulate the construction evolution over time. 4D CAD can fill several needs from design to project management through constructivity analysis and tasks planning (Tommelein 2003). The literature shows that several applications have been proposed to improve the 4D CAD use (Chau et al. 2004; Lu et al. 2007; Seok & al. 2009). In addition, studies have shown the real impact of 4D CAD use in construction projects (Staub-French & Khanzode 2007; Dawood & Sika 2007). More recently, Mahalingam et al. (2010) showed that the collaborative use of 4D CAD is particularly useful during the pre-construction phase for comparing the constructability of working methods, for visually identifying conflicts and clashes (overlaps), and as visual tool for practitioners to discuss and to plan project progress. So the advantage of the 4D CAD collaborative use is demonstrated. Moreover, several studies have been conducted both in the scientific community and in the industrial world to improve it (Zhou et al. 2009; Kang et al. 2007). But an important need that remains in collaborative 4D CAD use in construction projects is about the adaptation of visualization to the users business needs. Indeed, construction projects have very specific characteristics (fragmentation, variable team, different roles from one project to another). Moreover, in the AEC field several visualization techniques can represent the same concept and actors choose one or another of these techniques according to their specific needs related to the task they have to perform. For example, the tasks planning may be represented by a Gantt chart or by a PERT network and the building elements can be depicted with a 3D model or a 2D plan. The classical view (3D + Gantt) proposed to all practitioners in the available 4D tools seems therefore not suiting the needs of all. So, our research is based on the hypothesis that adapting the visualization to individual business needs could significantly improve the collaboration. This work relies on previous ones and aim to develop a method 1) to choose the best suited views for performed tasks and 2) to compose adapted multiple views for each actor, that we call ‚Äúbusiness views‚Äù. We propose a 4 steps-method to compose business views. The first step identifies the users‚Äô business needs, defining the individual practices performed by each actor, identifying his business tasks and his information needs. The second step identifies the visualization needs related to the identified business needs. For this purpose, the user‚Äôs interactions and visualization tasks are described. This enables choosing the most appropriate visualization techniques for each need (step 3). At this step, it is important to describe the visualization techniques and to be able to compare them. Therefore, we proposed a business view metamodel. The final step (step 4) selects the adapted views, defines the coordination mechanisms and the interaction principles in order to compose coordinated visualizations. A final step consists in a validation work to ensure that the composed views really match to the described business needs. This paper presents the latest version of the method and especially presents our latest works about its first and second steps. These include making more generic the business tasks description in order to be applicable within most of construction projects and enabling to make correspondence with visualization tasks.

title	Analysis of Design Support for Kinetic Structures
source	Vienna University of Technology; Building Science & Technology
summary	This thesis attempts the formation and systemization of a basis of knowledge and information, which is indispensable to turn a design support for kinetic structures into representation by means of a 3d animating program. Representation of kinetic structures by means of the existing ordinary software sources is possible; Nevertheless, such representation lacks of different important features and functions and results eventually in the total absence of a real model of the construction, which is valuable to the user of the program especially in the field of the kinetics, where everything depends on the movement: design not only requires, but demands for visualisation. A personal interest in kinetic architecture and therefore in the physical movement of structural elements in a building, as well as an attempt to “fathom” the possibility of changing this concept to visualization and modern reality by the use of a software are the main incentives of this master thesis. First, a general research will be performed in order to check the existence of similar or semisimilar proposals. The area in which the research will be held is the Bibliography in kinetic architecture and parametric design. A comparison of animation and 3D prototype software in well-known programs will focus on whether virtual weather conditions are considered as a parameter to the animation of the structure of the programs and case studies of several existing kinetic structures will be performed, in order to point out flaws and/or helpful commands in the programs in connection with the presentation of kinetic architecture. Criteria for the choice of the software: ability to customise and to produce geometric modelling, animation in relation to time (video animation) and the simulation after taking into consideration weather factors. Finally, using the computer and the scripting language, based probably on the theory of parametric design and primitive instancing, a realistic simulation of different elements will be performed in relation to variable measurements of luminance, ventilation and temperature so as to render feasible the construction of a whole structure. The results of the thesis will be used in the future as the basic knowledge in the creation of software for simulation of kinetic architecture. This program will be used as a tool for the architect to present a building, where kinetic architecture will be applied and to create simulation of the kinetic movement through a library of the existing prefabricated elements which will be created with the help of this thesis.

title	Building Information Modelling: Empowering Energy Conscious 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. 661-670
summary	The increasing awareness of climate change and carbon dioxide emissions from the built environment is resulting in the need to visualize the environmental performance of buildings. One of the recent drivers in the UK has been the tightening of building regulations relating to energy consumption in buildings, mandating all buildings to be performance evaluated by accredited environmental simulation tools to test their carbon dioxide emission against set targets. Currently there is major confusion on all levels from architects to building control officers and contractors on how to engrain energy consciousness principles in the design and construction of buildings. Within this context, ‘Building Information Modelling’ that is linked to ‘Building Performance Modelling’ is increasingly being looked upon as a tool to facilitate the communication between the design team and contractors and to provide a transparent information model on the specification and targeted energy consumption of all new/ refurbished buildings to all parties involved. In this paper, analysis of the benefits and drawbacks of current efforts to combine those two comprehensive databases will be investigated. A sample of main software development companies, architects and contractors, using semi-structured interviews is undertaken to find out how Building Integrated Modelling (BIM) and Building Performance Modelling (BPM) can support the design and construction teams to deliver energy conscious buildings.

title	Using Social Network Analysis for Visualising Spatial Planning During Conceptual Design Phase
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.i8r
summary	Spatial diagramming exercises with clients are difficult when most clients are not able to visualize the end results of their requirements. This paper would like to introduce a computational tool—Social Network Analysis (SNA)—commonly used in the communications field to study relationships between people we believe can resolve this visualization problem. Our research intent is to affirm whether or not we can use SNA as a spatial planning tool during conceptual building design. We posit that since the nodes and structural relationships between the nodes may have similar architectural characteristics, the tool would enable architects to make changes by moving any spaces on a floor plan while safely maintaining their spatial relationships to other spaces. In this paper, we would like to develop a proof-of-concept model using an available SNA tool to facilitate spatial diagramming visualization during conceptual design phase. We tested the use of a SNA tool at four levels. The first level determined whether we could develop spatial relationship between functional spaces (such as the living room must be adjacent to the front entry). The second level is on setting priorities values for the different nodes and the linkages. The third level determined whether we could develop grouping relationship between several functional spaces that have a common characteristic (such as public versus private spaces) on one horizontal plane. The final fourth level determined whether we could develop multiple layers that are connected by one common connector (such as a staircase in a double-story house). Our models are validated intellectually by visual comparison between our model and another diagramming by Nooshin (2001) that was developed manually. We are most interested in the fourth level because complexity in the spatial diagramming exercises is caused by multi-layered spatial arrangements at the horizontal and vertical planes. We expect our study to provide us guidelines in developing a prototype for a spatial diagramming tool using SNA, which architects can use to resolve visualization problems when conducting the exercise with their clients.

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	Applying generative modeling procedure to explore architectural forms
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. 697-712
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.

title	Simulating Dynamic Forces in Design with Special Effects Tools

summary	Special effects technology can facilitate dynamic sketching in the early stage of a design project without needing time-consuming effort. This form of sketching was tested in a design studio taught by the author. The study of dynamic materials and oceanfront site conditions set the stage at the beginning of a design process for a more comprehensive analysis later on. On the one hand, the risk of using special effects tools is that the visual look can seem convincing, but the apparent result is based upon an overly simplified set of assumptions. On the other hand, the use of such technology can be very stimulating to the design imagination without requiring complex analysis that may bog down the free flow of ideas. Once a greater commitment is made to a particular design proposal, more complete physical analysis and modeling can be undertaken to help avoid the risk of false first impressions. In the studio, cloth simulation was used to develop the design of tension membrane structures (tents) that retracted and unfurled in a series of complex movements. Fluid dynamics effects were used in the design and development of related boat dock facilities. A wind-tunnel simulation tool was used to explore the performance of the tension-membrane fabrics under varied wind loads. The visualization techniques were complemented by ¼ to ½ scale assembled components created by rapid prototyping. The use of an actual wind-tunnel further tested the prototypes in some cases. On the whole, quickly implemented special effects were the starting point for reacting to and developing some initial design concepts and served as the basis for more complete physical modeling of prototypes later on. Using animation as a design method is well established in other work (Hirschberg 06). Animation is also a helpful way to work out the step by step assembly of complex architectural form (Mark 95). The special effects tools permit a larger range of initial design alternatives to be initially considered that are subsequently narrowed down by physically based prototypes that are more predictive of real world performance.

title	Digital Resource Semantic Management of Islamic Buildings Case Study on Isfahan Islamic Architecture Digital Collection
source	International Journal of Architectural Computing vol. 5 - no. 2, pp. 356-373
summary	This article describes an innovative way to facilitate and to provide a collaborative semantic management of digital resources of Islamic historical buildings. The approach combines a topic maps-based semantic support to the 5W1H model (Where, Who, When, What, Who and How) with objective of enabling comprehensive semantics of digital contents for research and education purposes. The topic maps-based semantic support enables to reduce the problems of semantic gaps among different communities (cultural, linguistic ambiguities among various types of multi-disciplinary experts). Furthermore, a multi-faceted resource category management, applied to metadata sets and related semantic features, allows metadata optimization of the description of the cultural resources. This innovative approach has been used to build the Isfahan Islamic Architecture Database (IIAD) Collection as a case study. The research demonstrates that a topic maps-based semantic model applied to collaborative metadata management paradigms can be easily exploited as a tool to enhance traditional architectural and cross-disciplinary studies.

title	The Urban Simulation and Projects Evaluation Laboratory at the Politecnico di Milano: An Educational and Research Facility
source	Projecting Spaces [Proceedings of the 9th European Architectural Endoscopy Association Conference / ISBN 978-3-942411-31-8 ], pp. 115-120
summary	At the beginning of 2007 an Italian Urban Simulation Laboratory was founded at the Politecnico di Milano. The laboratory, coordinated by prof. Fausto Curti, has been developed thanks to the one year presence of the visiting professor Peter Bosselmann, director of the Environmental Simulation Laboratory at the University of California at Berkeley. The laboratory has an interdisciplinary approach and a threefold mission: experiment, using the laboratory setting to study urban projects at different scales; communicate, aiding public communication by making urban projects understandable to everyone; integrate and innovate, working on different kind of simulations techniques in an integrated way. In its initial experience the laboratory is primarily a didactic and research facility. Students can join the work and participate actively to the research. Until now about 40 students have worked with us, more than a half were foreign students from all over the world. The majority of the students did an internship of about 150 (three-year degree) or 300 (master degree) hours and some of them have continued working after this period developing a thesis. At the moment the case study, used as a pilot research, is about the Porta Nuova project at the Garibaldi- Repubblica area in Milan. The 300.000 mq of the total area and its well served central position make this place strategic for Milan. In this area the adopted urban transformation plan is creating a new business center that affects redevelopment projects, new infrastructures, and a park. The overall project will overhanging the surroundings city center with some of the highest buildings of its skyline. The importance of the site and the dimension of the project make this case significant to test the use of simulation for supporting evaluations about morphological aspects, comfort conditions, visual impacts, and other aspects that directly influence the quality of the new urban spaces. We are now applying different simulation methodologies in order to better understand the peculiar usefulness of each kind as a tool to support evaluation. As any kind has its own limits we work with different typologies at the same time. We are working with 1:500 scale physical model of a 1 km square of the area and different kind of static and dynamic simulations. We developed, with an external office, a micro-car to move a micro-camera in the maquette. We use this equipment to better explain the project implications to the students by producing subjective shot videos or showing a walk in real-time. To reproduce in a better way some relevant walks through the transformed site we have also produced some videos made of a superimposition of the real existing context and the virtual projects. To do this we used a rendered video of the project superimposed to the filmed promenade of the today condition, previously recorded using steadycam. A lot of static simulations has been employed to better understand the new city configuration from some representative points of view, as for example the roof of the Duomo cathedral. We are now developing some other kinds of analysis such as shadows impact; this is done by using a 1:1000 scale maquette in the Heliodon, but also with some digital tools. In the next future a work with the wind tunnel will help to understand some other comfort implications of the project at the micro-urban scale. The multilayer approach is the main aim of the laboratory and is an important tool to clarify the multidimensional project impacts to the students. In this way the laboratory can be a learning tool, it can stimulate the project process and support decision-making while improving the knowledge about the correct use of simulations for evaluating the cumulative implications of the proposed urban processes.

title	Various Media in the Design Process and Methodology
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.t8j
summary	The paper describes the mergence of traditional architectural design processes with approaches that rely on digital media and software for the creation of architectural space. The depicted projects are part of a ‘work in progress’ process, with a recent studio that is set up to apply the so far accumulated experiences. Within the projects, focus is on those design phases where the applied media and methodology is changed and where the back and forth between different media and the depth of their implementation is perceptible in, and / or has a significant influence on the design itself. Through a line of successive experiments, the paper explains the development of a possible method that utilizes a variety of today’s accessible tools in architecture, making use of phenomena that appear when changing from one tool to another. Goal is to avoid limitations that are existent by the solely employment of one media or method, and to understand the fusion between different media as an inspiring momentum to develop the design further. The paper draws a line from an initially experienced and analyzed design method over several projects in practice and academia to conclude with a possible design method that could be established successfully in both fields of architectural teaching and practice. Initial experiences had been drawn from professional practice, in which the digital realm was limited to a support device of the design process. The first project that is described in the paper, explored the employment of digital media as a possible tool to drive the design process in a broader sense. The studio setting was organized as a laboratory for the exploration of the change of applied media. Focus was on the influence on the design progress. The design method required of the studios participants was not exclusively based on an architectural program, but on an initial, very conceptual process with an artistic approach, based on personal experiences of each participant. This was meant to detach the students entirely from architectural processes and mindsets they had picked up so far. Parallel to that kind of an intellectual process, studio participants learned to handle Maya as the 3D modeling software of their choice. Both the technical knowledge and the artistic projects were merged in a second project phase, in which participants had to further develop their work by applying a very effective mix of various design tools. Using digital media as a parametric design generator, subsequent projects were developed. The task for the designers here were to decide what kind of algorithm could be applied to which process and when it was to be stopped for the best result. Applying such an automatism successfully to the design process, the employment of traditional media and methodology remained, to adapt the digital driven schemes to the required design task. The diverse design experiments demonstrate important aspects when merging complex design and animation software with traditional design processes. To achieve good architectural design results, all examined projects showed that traditional design methods with its physical models are hardly replaceable to its full extent by other media, but digital media are able to strengthen design processes and invite designers to explore new means of design work.

title	Representing BIM-based design process [Representando Procesos de Diseño Basados en BIM]
source	SIGraDi 2007 - [Proceedings of the 11th Iberoamerican Congress of Digital Graphics] México D.F. - México 23-25 October 2007, pp. 196-199
summary	This paper focuses on the study of parametric modeling using a BIM tool for conceptual design. In order to understand the use of BIM in the architectural design process, we compare the process of detail design and concept design using a BIM-based parametric tool. We present the results of two empirical studies: the design of a parametric curtain wall system, based on the work of 3 student teams; and the design of a parametric kinetic component, based on the work of 5 individual students. A comparative analysis of both processes is used to derive a process model.
