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	Soft Façade: Steps into the Definition of a Responsive ETFE Façade for High-rise Buildings
doi	https://doi.org/10.52842/conf.ecaade.2007.567

summary	Façade systems are to a great extent responsible for both the energy-performance and overall aesthetic qualities of a building. The study presented in this paper explores the tectonic integration of a distributed computer network and the façade of a high-rise tower through the use of ETFE cushions, exploiting the soft nature of this material to embed a sensor network to provide touch-responsive changes of opacity in the façade, potentially improving the energy-efficiency of a building, and promoting a novel kind of dialogue between a space and its inhabitants. We propose that the inclusion of computer networks and displays in the built environment necessarily leads to new design philosophies that solve tectonically the dialogue between traditional materials and technological devices, and we put forward the first results of a research into a novel implementation of electrochromic ‘smart’ cushions that allows for changing opacities of the façade elements of a building in response to human touch.

title	Using Social Network Analysis for Visualising Spatial Planning During Conceptual Design Phase
doi	https://doi.org/10.52842/conf.caadria.2007.x.i8r
source	CAADRIA 2007 [Proceedings of the 12th International Conference on Computer Aided Architectural Design Research in Asia] Nanjing (China) 19-21 April 2007
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	On Slime Molds and Corridors - The application of network design algorithms to connect architectural arrangements
source	Parametricism Vs. Materialism: Evolution of Digital Technologies for Development [8th ASCAAD Conference Proceedings ISBN 978-0-9955691-0-2] London (United Kingdom) 7-8 November 2016, pp. 95-104
summary	The use of adjacency graphs to represent and generate architectural arrangements tends to favor direct connections between contiguous rooms. These disregard specialized circulatory systems (such as corridors), which consider connections between non-contiguous spatial units or accesses. This paper addresses two specific issues: (1) how to represent a circulation network for a specific access/adjacency graph embedding; and (2) how to design good circulatory solutions for the arrangement that optimizes this network. To represent a complete circulation network, we propose a scheme, an adapted straight skeleton, based on the boundaries of the spatial units. To design possible circulation alternatives, we adopt the Slime Mold model (Tero et al., 2006; 2007). Using this model, we develop an original method, termed Adjacency Graph Selection (AGS), to generate circulation solutions for arrangements. As an initial test case for AGS, we use floor plan of the Louvre Abu Dhabi, designed by the French architect Jean Nouvel.

title	Simulation Software Development for Urban Landscape Possibility Analysis
doi	https://doi.org/10.52842/conf.caadria.2007.x.u9u
source	CAADRIA 2007 [Proceedings of the 12th International Conference on Computer Aided Architectural Design Research in Asia] Nanjing (China) 19-21 April 2007
summary	This research paper proposes a simulation software development for possibility analysis of urban landscape development project. Normally, analysis of land potentiality and feasibility study for investment are necessary pre-processed for supporting urban planning, developing and architectural designing. However, most available tools are usually tailor made for each process individually, causing difficulties in information interchange between each processes. In this research, we propose a policy making support system for urban planning project development providing several functions such as testing land use and its physical character which are important to urban expansion and architectural design based on impact analysis of urban comprehensive plan. The proposed integrated system consists of a topological analysis module, constraint checking module and geographical information processing module. First, Geographical information stored in 3D graphic file format is converted to object-oriented data model and stored in a database. With several constraint and regulations, the stored information is then checked in the landscape topological analysis module. In evaluation process, the developed software is tested with geographical information of Bangkok area under constraints and regulations of Building Control Act of Thailand. While controlling building properties, the software can model the buildings and generate urban physical character. The result is then checked by several urban landscape planning experts. Experimental result shows that proposed system provides flexibility in information interchanging with constraints and regulations updating without system reconfiguration. The system also provides internet accessing for public participation in the process of making urban comprehensive plan.

title	Conceptual Design of High-rises with Parametric Methods
doi	https://doi.org/10.52842/conf.ecaade.2007.293
source	Predicting the Future [25th eCAADe Conference Proceedings / ISBN 978-0-9541183-6-5] Frankfurt am Main (Germany) 26-29 September 2007, pp. 293-301
summary	This paper describes the use of parametric methods in generating conceptual designs of high-rise buildings. We first assess current conceptual design practice at a leading AE firm and illustrate the challenge of satisfying a complex set of requirements with the tools currently used by the AEC industry. Few design options are generally developed and analyzed; better design solutions are most likely being overlooked. Parametric tools can potentially help address this problem by allowing designers to formalize and generate solution spaces that can be explored. But few case studies exist to document the construction and impact of these models. We present such a case study. We describe the variables, constraints, components, and rules in the model. We discuss the costs and benefits, and conclude with recommendations for expanding the use of parametric methods.

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	Collaborative Knowledge Construction in Digital Free-Form Design
doi	https://doi.org/10.52842/conf.ecaade.2007.735
source	Predicting the Future [25th eCAADe Conference Proceedings / ISBN 978-0-9541183-6-5] Frankfurt am Main (Germany) 26-29 September 2007, pp. 735-742
summary	This paper focuses on the emerging domain of digital free-form design, and attempts to explicate its knowledge content and characteristics through a systematic inquiry of the digital free-form design practice. The massive amount of information associated with the design and construction demands of the complexly shaped buildings demand explicit knowledge about the way various information pieces relate to one another. This paper reports on the process of developing a knowledge framework which serves as a reference model to describe and explain the free-form design and production processes in terms of the interaction of contextual conditions and according to the different ways design problems are perceived and formulated by the members of the design teams. The framework provides guidelines for the development of a web-based design decision support system to support collaborative knowledge construction, sharing and reuse in the domain.

title	Architecture on Digital Flatland: Opportunities for Presenting Architectural Precedence
doi	https://doi.org/10.52842/conf.acadia.2007.110

summary	The importance of precedent-based learning in architecture is well recognised by education researchers. Therefore, attention needs to be paid to the sources of building information and their presentation. This paper provides an overview of a research project that deals with the delivery of information of notable buildings specifi cally on computer screen for the purpose of accessibility to the wider public in general, and architectural students in particular. The paper highlights the critical need to reassess the effectiveness of current available publications. Apart from their traditional print format, architectural publications of design precedents are also swiftly advancing into the digital platform. This platform’s potential to contribute to in-depth learning within the discipline has to be explored and exploited. This paper describes an illustrative prototype digital interactive system that explores the potential of visual content and digital capabilities to showcase and present architecture on digital ‘flatland.’ It adopts Murcutt, Lewin and Lark’s, The Arthur and Yvonne Boyd Education Centre in New South Wales, Australia for the model, while outlining the aims, process, and considerations for its implementation. Finally, it reports on a general assessment of responses from a focus group.

title	Location Based Services in Revitalization: The Use of Commonly Available Techniques for a Client-Participation Model
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. 505-516
summary	This research concentrates on the combination of remote sensing devices, georeferenced data, web-based optimization techniques and Location Based Services in revitalization. Its aim is to enhance the delivery of information about the development potentialities of existing buildings. The present and idle stock of buildings is extensive. Nonetheless, significant data and information about existing buildings is hardly available. The real estate owners are usually not known by prospective clients and they can be elicited only with substantial effort. But even if data about a building is available it is difficult to valuate it precisely, because of missing standard classification techniques. The question whether or not a building is suitable for a certain subsequent use is therefore hard to answer. It involves an extensive expenditure of time and manpower. Recent publications however, demonstrate that requests for the re-use of buildings can be solved through the use of combinatorial optimization techniques (Loemker 2006a, 2006b, 2007). Within these approaches researchers mainly concentrate on the architect dealing with inquiries from clients. These inquiries typically address the question if specific buildings are suitable for particular future uses. With the aid of optimization engines the architect can solve these requests through a description of the existing buildings and the corresponding enquiries in terms of specific criteria such as number and size of rooms or adjacency between rooms. According to an unambiguous syntax these approaches can be applied to any building type. The building data is stored in databases which can be inquired through optimization engines which thereupon calculate suitable solutions to the demands made by the client. But even if these approaches demonstrate high potential, their bottleneck lies in the exclusive use through the architect. Neither can they be addressed to buildings that are not listed in the architects own inventory listings nor can they be used by the clients themselves. Furthermore, no reliable statement about a prospective reuse of a building can be made directly on site by prospective clients, i.e. buyers or renters. In our research we examined if ad-hoc analyses of existing buildings can be accomplished through the clients themselves with the aid of Location Based Services that can be accessed by common remote sensing devices. The aim is to give prospective clients the possibility to visit a building and run in-situ usability simulations. To accomplish this, building data will be transferred between the building and the client through the use of ordinary communication devices. These devices automatically connect to server-based applications, which compare the requirements of the client with the existing building and run remote simulations on concrete further utilization. The newly generated information will then be passed back to the client’s device. In the paper we address a scenario of a prospective client who visits a city where he hits on an unused building he might be interest in. The client wishes to gain immediate and accurate information if the building is able to meet his demands regarding the space needed for his company. Different techniques investigated, their assets and drawbacks will be described that could accomplish suchlike tasks.

title	Preservation of existing buildings through methods of Operations Research
source	DACH 2007, International Conference on Digital Applications in Cultural Heritage, P. 157-175
summary	The revitalization of existing buildings is getting more and more important. We are facing a situation where in many cases there is no need to design new buildings because an increasing number of existing buildings is not used anymore. The most ecological procedure to revitalize these buildings would be through a continuous usage and by making few or no alterations to the stock. Thus, the modus operandi could be named a “non-destructive” approach. From the architects’ point of view, non-destructive redesign of existing buildings is time-consuming and complex. The methodology we developed to aid architects in solving such tasks is based on exchanging or swapping utilization of specific rooms to converge in a design solution. In this regard, it was examined whether solutions for reuse tasks can be produced automatically by the use of optimization processes in floor plan design. These solutions shall be produced by swapping of existing areas. The objective is to obtain feasible planning solutions by means of these computer-based processes, which will serve the architect as a basis for the further editing of the plans. The methodical basis for this procedure is formed by models from Operations Research. The design of the model developed relates to problems in logistics, for example, the loading in trans-shipment centers. It also has analogies to board games like Chess or Go. These games are based on a specific number of fields or crosses of grid lines which are occupied by various tokens. Occupation is subject to a variety of conditions or rules. Compliance to conditions and objectives is clearly defined by the use of these rules. The analogy to our model is the fixed grid, the limited possibility to occupy fields and the fulfillment of an overall goal, i.e., to win the game. Therefore the model does not alter geometric proportions or locations of rooms but changes their occupancy such that a new usage could be applied to the building.

title	The Creation of Urban Form: A Normative Approach to Modelling
doi	https://doi.org/10.52842/conf.caadria.2007.x.t8k
source	CAADRIA 2007 [Proceedings of the 12th International Conference on Computer Aided Architectural Design Research in Asia] Nanjing (China) 19-21 April 2007
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	Building Information Modelling of Modern Historic Buildings
doi	https://doi.org/10.52842/conf.ecaade.2007.607
source	Predicting the Future [25th eCAADe Conference Proceedings / ISBN 978-0-9541183-6-5] Frankfurt am Main (Germany) 26-29 September 2007, pp. 607-613
summary	This paper reports a research study which evaluated the possibilities of building information modelling (BIM) within renovation of buildings of significant architectural, historic or cultural values. Renovation or restoration projects of historic buildings can be more demanding, challenging and complex than traditional renovation of for instance within housing. Objective of this research has been to transfer ICT (information and communication technology) and BIM research findings to historic design practice and true renovation project environments. The concept of building information modelling BIM is a proposed integrative framework for all design and construction project information in digital form. BIM can currently be seen to be in a phase of pragmatic pilot projects in several countries. Nevertheless, BIM has not been tested that much in renovation projects yet, although the importance of renovation and restoration is remarkable within the total volume of western construction sectors. One essential conclusion of this study is, that renovation design work should be started earlier in model-based design projects than in traditional renovation projects. More resources have also to be assigned to earlier design phases, if BIM is intended to be used extensively throughout the project. Another finding is the new concept of an inventory model, which is proposed to be the container for all building inventory, survey and measurement data. Even more so, when significant historic, hence more demanding building renovation is concerned, because there are more needs for various kinds of surveys, accurate data gathering and analyzing queries concerning the project.

title	Designing with images: Augmented reality supported on-site Trompe l’oeil
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. 275-290
summary	Activities in the building industry in Germany concentrate increasingly on a combination of renovation and new-build. A look at current computer aided applications reveals a serious lack of IT support for the whole architectural design process with and within existing buildings (e.g. building surveying, designing on site and the preparation of information for further use in later planning stages). An ongoing interdisciplinary research project undertaken jointly by the faculty of media and the faculty of architecture is investigating methods and techniques for the computer-aided support of the design process with and within existing buildings. The goal is to develop a hardware and software concept for a “design-toolbox” based on SAR (spatial augmented reality) and to implement aspects of it as prototypes. The paper focuses on one aspect of the research project – designing with images in an AR-Environment. The paper presents an overview of the project, a description of the core model based on a client-server architecture, the historical / theoretical architectural background and first results of this research part. The project is funded by the “German Research Foundation (DFG)”.

title	The Categorisation of Data from Smart Buildings for a positive Sustainable Application
doi	https://doi.org/10.52842/conf.caadria.2007.x.h3i
source	CAADRIA 2007 [Proceedings of the 12th International Conference on Computer Aided Architectural Design Research in Asia] Nanjing (China) 19-21 April 2007
summary	This paper describes an architecture oriented approach of a categorization of information in so called computer integrated buildings (CIB). It follows an approach which seeks for the suitability of information categorization in order to achieve an energetically sustainable operation of CIBs. The CIB and its environment may exist as physical objects or as a simulation. The underlying question of this paper is: how can data of high temporal and spatial density be made accessible within a CIB with the goal of quickly delivering the most suitable answers for a specifical application. The subtitle „Google™ in the House“ was chosen due to the achievable relation of a model with simple user interfaces, extendable pre-valuable data basis and high quality answers is being developed. The model’s foundation is the potential of any built context that it is very easy to position data in physical space by adding its position by Cartesian coordinates. This architectural way of pre-sorting data is defined as logical arranging. Further on, known mechanisms of information retrieving and mapping are added to the model. A preliminarily summary concludes that energetically sustainable operations are backed through means of computational categorization models.

title	A Theoretical Framework for the Implementation of Building User’s Lifestyle in nD CAD System

summary	People’s lifestyle, traditions and culture affect the way they live, interact with the built environment and erect buildings. Lifestyle influences the physical characteristics of the space such as: organization of spaces, distances between spaces and location of spaces. Taking lifestyle aspects into account by architects would provide comfortable environment that is tailored to people needs and aspirations. On the other hand, rapid developments in computer modeling of buildings since 1960, led to the invention of 3D CAD systems that are capable of modeling the physical volume, shape and form of buildings and helping project team members to virtually visualize buildings. 4D CAD systems went beyond the mere 3D modeling of the physical building as they link the 3D virtual building model with other building’s information such as construction process, cost estimation etc. The nD CAD research that emerged in the late 1990s proposed endless dimensions of CAD modeling that would include the building regulations’ requirements, basic user needs and client requirements. This paper argues that it would not be enough to model the client requirements and some of user/ occupant’s physical and environmental aspects as it does not reflect the real utilization of the building by building’s user and the way that he/ she likes to live. This research aims to define the lifestyle characteristics of the architectural space and its boundaries. It suggests that various aspects of the user’s lifestyle such as degree of privacy, flexibility and adaptability required for each space, organization of internal spaces and style of spaces should be implemented in the future nD CAD models. Such implementation would enable designers to consider real life scenarios, model the real needs of people and provide the adequate end product for them.

title	Teaching Building Information Modeling (BIM) from a Sustainabilty Design Perspective
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. 635-650
summary	Building Information Modeling has recently gained significant attention both in academia and practice. BIM presents immense opportunities for increased efficiencies, coordination and quality of architectural design. One of the reasons that BIM offers a more comprehensive design approach is the fact that all aspect of the building are considered during the modeling phase. Rather than drawing the building using lines and circles actual object are used to model the building, which results in a more comprehensive underlying database model of the entire edifice being designed. The approach obviously has tremendous benefits in terms of coordination and systems integration, as well as, project control and management during the design and construction phases. Nevertheless BIM offers its own unique challenges vis-à-vis its introduction to students of architecture. The students in Architecture programs are usually introduced to BIM in two ways, either through a specialized course in CAD or via a shadow introduction in design studios and related courses. Careful positioning of the course within the architecture curriculum is crucial in order to gain maximum benefit in the synthesis of other course content. The reason being that students of architecture in earlier years of the design curriculum may not yet have developed the ability to synthesize and coordinate multiple systems required for complete BIM. This is an important consideration the design and pedagogy of introducing BIM to Architecture students. This paper argues for a new approach in teaching BIM for Architecture students. Instead of designing a course specifically for BIM/CAAD we present a paradigm whereas BIM can be presented within a larger more rigorous context. The experience of teaching BIM within a sustainable design framework is presented in this paper. Issues relating to the design of basic residential buildings were integrated into the course presenting BIM. A simplified set of design rules and guidelines under banner of sustainability were taught to the students in pre-defined doses and sequence throughout the course. The careful placement of these concepts permitted for BIM to be introduced in a more interesting and comprehensive manner than in the traditional CAD-course setting. Samples of student work are presented and critiqued in order to come up with recommendations and guidelines for incorporating BIM into a comprehensive and comprehensible course. The pedagogical advantages of and disadvantages of the approach are discussed within the paper, as well as, a detailed description of the course content and structure. Results from and outcome-based assessment of the objectives of the course are also illuminated which provided suggestions for future offerings of the course.

title	Procedural Design of Urban Open Spaces

summary	This paper presents a novel approach for the automatic creation of vegetation scenarios in real or virtual 3D cities in order to simplify the complex design process and time consuming modeling tasks in urban landscape planning. We introduce shape grammars as a practical tool for the rule-based generation of urban open spaces. The automatically generated designs can be used for pre-visualization, master planning, guided design variation and digital content creation in general (e.g. for the entertainment industry). In a first step, we extend the CGA shape grammar by Müller et al. (2006) with urban planning operations. In a second step, we employ the possibilities of shape grammars to encode design patterns (Alexander et al., 1977). Therefore, we propose several examples of design patterns allowing for an intuitive high-level placement of objects common in urban open spaces (e.g. plants). Furthermore, arbitrary interactions between distinct instances of the vegetation and the urban environment can be encoded. With the resulting system, the designer can efficiently vegetate landscape and city parks, alleys, gardens, patios and even single buildings by applying the corresponding shape grammar rules. Our results demonstrate the procedural design process on two practical example scenarios, each one covering a different scale and different contexts of planning. The first example illustrates a derivation of the Garden of Versailles and the second example describes the usage of high-level rule sets to generate a suburbia model.

title	Topology of Urban Environments: Graph construction from multi-building floor plan data
source	Computer Aided Architectural Design Futures / 978-1-4020-6527-9 2007 [Proceedings of the 12th International Conference on Computer Aided Architectural Design Futures / 978-1-4020-6527-9] Sydney (Australia) 11–13 July 2007, pp. 115-128
summary	This paper introduces a practical approach to constructing a hybrid 3D metrical–topological model of a university campus or other extended urban region from labeled 2D floor plan geometry. An exhaustive classification of adjacency types is provided for a typical infrastructure, including roads, walkways, green-space, and detailed indoor spaces. We extend traditional lineal techniques to 2D open spaces, incorporating changes in elevation. We demonstrate our technique on a dataset of approximately 160 buildings, 800 floors, and 44,000 spaces spanning indoor and outdoor areas. Finally, we describe MITquest, a web application that generates efficient walking routes.
