summary	This article is a starting point for the development of experiential urban co-design interfaces to enhance public participation in local urban projects and to be also used as a communication and collaboration tool in urban design. It is based on the previous research involving 3D city models utilized as understandable design interfaces for the non-technical public (Jutraz, Zupancic, 2011), where we have already explored different views (pedestrian, intermediate and bird’s-eye view), as well as the means by which the information obtained from these different views may be combined by shifting between viewpoints. Previous work was conducted in the “street lab” as well as the Urban Experimental Lab, which was developed specifi cally for the public’s participation in urban planning (Voigt, Kieferle, Wössner, 2009). Presented in this article is the next step that explores the immersive collaboration environment 3D ICC [1], formerly known as Teleplace. The environment was developed for effi cient collaboration and remote communication and shifts the research focus towards questions regarding how to employ both labs as interfaces between the non-technical public and design professionals. As we are facing the lack of digital systems for public participation and education in urban design, different digital tools for communication and collaboration should be combined into a new holistic platform for design. A digital system of tools needs to be developed that supports the urban design decision-making process and focuses on improved final solutions and increased satisfaction amongst all participants. In this article the system of digital tools for public participation, which include communication, collaboration and education, will be also defi ned, with its basic characteristics and its elements.

title	Top-down Approach for Interaction of Knowledge-Based Parametric Objects and Preliminary Massing Studies for Decision Making in Early Design Stages
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. 149-164.
summary	Design activities vary from high-degree of freedom in early concept design stages to highly constrained solution spaces in late ones. Such late developments entail large amount of expertise from technical domains. Multiple parallel models handle different aspects of a project, from geometric master models to specific building components. This variety of models must keep consistency with the design intent while they are dealing with specific domains of knowledge such as architectural design, structure, HVAC, MEP, or plumbing systems. Most of the expertise embedded within the above domains can be translated into parametric objects by capturing design and engineering knowledge through parameters, constraints, or conditionals. The aim of this research is capturing such expertise into knowledge-based parametric objects (KPO) for re-usability along the design process. The proposed case study ‚Äì provided by SOM New York‚ is the interaction between a massing study of a high-rise and its building service core, which at the same time handles elevators, restrooms, emergency stairs, and space for technical systems. This project is focused on capturing design expertise, involved in the definition of a building service core, from a high-rise senior designer, and re-using this object for interaction in real-time with a preliminary massing study model of a building, which will drive the adaption process of the service core. This interaction attempts to provide an integrated design environment for feedback from technical domains to early design stages for decision-making, and generate a well-defined first building draft. The challenges addressed to drive the instantiation of the service core according to the shifting characteristics of the high-rise are automatic instantiation and adaptation of objects based on decision rules, and updating in real-time shared parameters and information derived from the high-rise massing study. The interaction between both models facilitates the process from the designer‚Äôs perspective of reusing previous design solutions in new projects. The massing study model is the component that handles information from the perspective of the outer shape design intent. Variations at this massing study model level drive the behavior of the service core model, which must adapt its configuration to the shifting geometry of the building during design exploration in early concept design stages. These variations depend on a list of inputs derived from multiple sources such as variable lot sizes, building type, variable square footage of the building, considerations about modularity, number of stories, floor-to-floor height, total building height, or total building square footage. The shifting combination of this set of parameters determines the final aspect of the building and, consequently, the final configuration of the service core. The service core is the second component involved in the automatic generation of a building draft. In the context of BIM, it is an assembly of objects, which contains other objects representing elevators, restrooms, emergency stairs, and space for several technical systems. This assembly is driven by different layouts depending on the building type, a drop-off sequence, which is the process of continuous reduction of elevators along the building, and how this reduction affects the re-arrangement of the service core layout. Results from this research involves a methodology for capturing design knowledge, a methodology for defining the architecture of smart parametric objects, and a method for real-time-feedback for decision making in early design stages. The project also wants to demonstrate the feasibility of continuous growth on top of existing parametric objects allowing the creation of libraries of smart re-usable objects for automation in design.

summary	In strategic planning and design, planners can benefit a great deal from planning models and simulations (2D, 3D and 4D). Carrying out strategic planning and design with the support of (spatial) models can open up a bright spectrum of opportunities and insights that were not evident before. Planning models and simulations support an awareness-raising process. In this context, space syntax also fits in. In the following we will discuss the constraints and opportunities of space syntax and show how space syntax can add value to strategic planning and design (based on the Ljubljana masterplan) for a sustainable and sustaining built environment.

title	Pedestrian Modeling as Generative Mechanism for the Design of Adaptive Built Environment
doi	https://doi.org/10.52842/conf.ecaade.2011.850

summary	The investigation of the relationship between pedestrian modeling and the built environment is essential in the process of analyzing, evaluating and generating new architectural spaces that can satisfy circulation design conditions and respect the surrounding environment in the best possible way. In order to achieve the direct interaction between the users and the environment, current work attempts to examine how pedestrian models can be used as generative mechanisms for the production of adaptive spaces, which can be optimized according to human movement behavior needs. In this investigation, an existing computer program will be further developed in relation to its ability to inform the environment in an adaptive manner resulting the formation of spaces that can influence and can be influenced by pedestrian movement behavior and hence circulation systems. This can be done by creating new rules of interaction between components, for instance between pedestrians and the geometry of environment, and by taking into account pedestrian movement behavior conditions, as well as functional and morphological architectural design criteria.

title	Sketch-based Methods for Researching Building Layouts through the Semantic Fingerprint of Architecture
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. 85-102.
summary	The paper focuses on the early stages of the design process where the architect needs assistance in finding reference projects and describes different aspects of a concept for retrieving previous design solutions with similar layout characteristics. Such references are typically used to see how others have solved a similar architectural problem or simply for inspiration. Current electronic search methods use textual information rather than graphical information. The configuration of space and the relations between rooms are hard to represent using keywords, in fact transforming these spatial configurations into verbally expressed typologies tends to result in unclear and often imprecise descriptions of architecture. Nowadays, modern IT-technologies lead to fundamental changes during the process of designing buildings. Digital representations of architecture require suitable approaches to the storage, indexing and management of information as well as adequate retrieval methods. Traditionally planning information is represented in the form of floor plans, elevations, sections and textual descriptions. State of the art digital representations include renderings, computer aided design (CAD) and semantic information like Building Information Modelling (BIM) including 2D and 3D file formats such as Industry Foundation Classes (IFC) (IAI, 2010). In the paper, we examine the development of IT-technologies in the area of case-based reasoning (Richter et al., 2007) to provide a sketch-based submission and retrieval system for publishing and researching building layouts including their manipulation and subsequent use. The user interface focuses on specifying space and their relations by drawing them. This query style supports the spatial thinking approach that architects use, who often have a visual representation in mind without being able to provide an accurate description of the spatial configuration. The semantic fingerprint proposed by (Langenhan, 2008) is a description and query language for creating an index of floor plans to store meta-data about architecture, which can be used as signature for retrieving reference projects. The functional spaces, such as living room or kitchen and the relation among on another, are used to create a fingerprint. Furthermore, we propose a visual sketch-based interface (Weber et al., 2010) based on the Touch&Write paradigm (Liwicki et al., 2010) for the submission and the retrieval phase. During the submission process the architect is sketching the space-boundaries, space relations and functional coherence's. Using state of the art document analysis techniques, the architects are supported offering an automatic detection of room boundaries and their physical relations. During the retrieval the application will interpret the sketches of the architect and find reference projects based on a similarity based search utilizing the semantic fingerprint. By recommending reference projects, architects will be able to reuse collective experience which match the current requirements. The way of performing a search using a sketch as a query is a new way of thinking and working. The retrieval of 3D models based on a sketched shape are already realized in several domains. We already propose a step further, using the semantics of a spatial configuration. Observing the design process of buildings reveals that the initial design phase serves as the foundation for the quality of the later outcome. The sketch-based approach to access valuable information using the semantic fingerprint enables the user to digitally capture knowledge about architecture, to recover and reuse it in common-sense. Furthermore, automatically analysed fingerprints can put forward both commonly used as well as best practice projects. It will be possible to rate architecture according to the fingerprint of a building.

title	Change Detection in 3D Parametric Systems: Human-Centered Interfaces for Change Visualization
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. 751-764.
summary	The research on current parametric modeling systems concerns mainly about the underlying computational technology and designs produced; and emphasizes less human factors and design tasks. We observe users being challenged in interacting with these systems regardless of their expertise level. In these systems, user’s attention is divided on system-imposed actions such as tool selection and set-up, managing obscured views, frequent view manipulation, and switching between different types of representations. In essence, control of the system can become more demanding than the design task itself. We argue that this unbalanced emphasis inhibits one of the most important functions of parametric design: agility in exploration of design alternatives by applying frequent user-introduced or system-generated changes on the parametric design models. This compounded by the effect of cognitive limitations such as change blindness and shifts in locus of attention hinders change control and imposes an extra cognitive load in design. In this paper, we made a first step in developing a set of heuristics that is going to present how designers’ change control and detection can be improved. We experimented with three interfaces that control and visualize changes on three different compositions in relation to the designer’s locus of attention: on-model, peripheral and combined views. We measured designers’ performance as the number of changes detected, number of trials, and time required to complete each change detection task. The results support our hypothesis that change blindness significantly slows down and overloads design thinking, and thus should not be ignored. Furthermore, an interesting finding shows that visualizations on the visual periphery can equally support change detection as on-model visualizations, but it is significantly easier and faster to detect changes when they are visualized in both views. These findings can guide us to develop better interfaces in 3D parametric systems.

title	Colour-code models: The concept of spatial network
doi	https://doi.org/10.52842/conf.caadria.2011.707
source	Proceedings of the 16th International Conference on Computer Aided Architectural Design Research in Asia / The University of Newcastle, Australia 27-29 April 2011, pp. 707-716
summary	The main goal for the architects or planners is to understand a perspective of the user. The foundation of the design process is to create buildings and environments, which will be both innovative and functional for all types of users, including adults and children. While planning the environments for children the particular aspects should be considered. The important questions are: What kind of contact does child have with the city, urban places and buildings? How does the child construct the picture of the city? What kind of urban or architectural spaces contributes to the relation that a child has with the environment? Most of the previous studies concentrating on creation of spaces for children have focused on the perspectives that have adults. According to CAADRIA 2010 paper, the objective of our study was to “learn about” (get to know the) children’s perception of everyday places. The main goal of the project was to define an appropriate tool for the design process. We identified three elements, which were considered to be the most important for child’s identification with environment: home, school, and the journey from home to school. For this purpose, children living in a residential community in Bangkok were surveyed. Contrariwise to the quantitative approach (Neisch, 2010), the concept of Colour – Code Models of space propose a qualitative development of this research – a graphic language which allow to understand the children’s spatial world, the novel way to analyze and present space, useful for educate architects and planners.

title	Form Follows Performance: Structural Optimisation and the Cost-effectiveness of Digital Fabrication
doi	https://doi.org/10.52842/conf.ecaade.2011.837
source	RESPECTING FRAGILE PLACES [29th eCAADe Conference Proceedings / ISBN 978-9-4912070-1-3], University of Ljubljana, Faculty of Architecture (Slovenia) 21-24 September 2011, pp.837-842
summary	The presented paper describes a series of studio-based research projects on structural optimisation and the cost-effectiveness of digital fabrication that aim to balance stress distribution across thick walls or a rib density of slabs. As a consequence of the structural optimisations, the results tend to be non-uniform shapes that are not ideal for cost-effective fabrication. This paper introduces a few simple models to balance structural optimisation and fabrication cost-effectiveness. It involves relatively simple structural simulations as the design inputs, and then converts the simulation results into various architectural forms using parametric 3D modelling tool (McNeel Rhinoceros v4, Grasshopper v0.8) before fabricating them using digital fabrication technologies. The major challenge of this study is how to translate simulation results into architectural components/overall building shapes and how to fabricate complex forms in a cost-effective manner.

title	An Urban Information Framework to support Planning, Decision-Making & Urban Design
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. 653-668.
summary	This paper reports on a 2-year research project undertaken in collaboration with a state planning authority, a major city municipal council and a government-owned development organisation. The project has involved the design of an urban information model framework with the aim of supporting more informed urban planning by addressing the intersection where an individual building interfaces with its urban context. This adopted approach enables new techniques that better model the city and its processes in a transparent and accessible manner. The primary driver for this project was the challenge provided by the essential incompatibility between legacy GIS (geographic information system) datasets and BIM (building information model) representations of the built form. When dealing with urban scale information, GIS technologies use an overlay mapping metaphor linked to traditional relational database technologies to identify features or regions in the urban landscape and attach attribute data to those in order to permit analysis and informed assessment of the urban form. On the other hand, BIM technologies adopt an object-oriented approach to model the full three-dimensional characteristics of built forms in a way that captures both the geometric and physical attributes of the parts that make up a building, as well as the relationships between those parts and the spaces defined by the building fabric. The latter provides a far richer semantic structure to the data, while the former provides robust tools for a wide range of urban analyses. Both approaches are widely recognised as serving well the needs of their respective domains, but there is a widespread belief that we need to reconcile the two disparate approaches to modelling the real world. This project has sought to address that disjunction between modelling approaches. The UrbanIT project concentrated on two aspects of this issue: the development of a framework for managing information at the precinct and building level through the adoption of an object-oriented database technology that provides a platform for information management; and an exploration of ontology tools and how they can be adopted to facilitate semantic information queries across diverse data sources based on a common urban ontology. This paper is focussed on the first of those two agendas, examining the context of the work, the challenges addressed by the framework and the structure of our solution. A prototype implementation of the framework is illustrated through an urban precinct currently undergoing renewal and redevelopment, finishing with a discussion of future work that comes out of this project. Our approach to the implementation of the urban information model has been to propose extensions to ISO/PAS 16739, the international standard for modelling building information that is commonly known as IFC (Industry Foundation Classes). Our reason for adopting that approach is primarily our deep commitment to the adoption of open standards to facilitate the exchange of information across the built environment professions, but also because IFC is based on a robust object schema that can be used to construct a internet-accessible database able, theoretically, to handle the vast quantity of data needed to model urban-scale information. The database solution comes with well-established protocols for handling data security, integrity, versioning and transaction processing or querying. A central issue addressed through this work is concerned with level of detail. An urban information model permits a very precise and detailed representation of an urban precinct, while many planning analyses rely on simplified object representations. We will show that a key benefit of our approach is the ability to simultaneously maintain multiple representations of objects, making use of the concept of model view definitions to manage diverse analysis needs.

title	Single Image Ambiguity and Adjustment of Cultural Heritage Modeling Approach
doi	https://doi.org/10.52842/conf.ecaade.2011.099
source	RESPECTING FRAGILE PLACES [29th eCAADe Conference Proceedings / ISBN 978-9-4912070-1-3], University of Ljubljana, Faculty of Architecture (Slovenia) 21-24 September 2011, pp.99-106
summary	The objective of this research is to point out the deficiency of the modeling from a single image and give suggestion for the improvement. In the domain of cultural heritage visualization, single image modeling is mainly used to recover the scene shown in the historical photographs. In this paper, some common ambiguities in the area of the historical architectural environments are highlighted. In most approaches user is the one to introduce and choose constraints, and therefore he must have control over the ambiguity problems. We propose suggestions about how to adjust the single-image-based modeling in order to minimize chance for irregular 3D shapes to emerge due to ambiguity. Simple examples are used to illustrate how ambiguity of a single image can affect the models veridicality, which are the common mistakes that inexperienced user can make and how and when they can be corrected.

title	Navigating Complex Models in Collaborative Work for (Sustainably) Integrated Design
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. 619-636.
summary	Increasingly intensive use of computational techniques such as parametric-associative modeling, algorithmic design, performance simulations and generative design in architecture, engineering and construction are leading to increasingly large and complex 3D building models which in turn require increasingly powerful techniques in order to be manipulated and interpreted effectively. Further complexities are of course due also to the multi-disciplinary nature of building projects, in which there can be significant variation and even conflict among the aims of architects, engineers and builders, as well as owners, occupants and other stakeholders in the process. Effective use of model information depends to a large extent on sense-making, which can in some ways be helped but also hindered by schemes for organizing the information contained. Common techniques such as layering, labeling (aka ‚Äòtagging‚Äô) and assignment of various other attributes to model objects have significant limitations ‚Äì especially those arising from general problems of language, ontology and standardization, as well as but distinct from issues of interoperability ‚Äì both with respect to locating the desired items in a 3D building model and also with respect to displaying the objects in informative ways which effectively assist collaborative design and decision-making. Sustainable design in particular is an area generally requiring a high level of inter-disciplinary collaboration to achieve highly integrated designs which make multiple use of the elements and systems incorporated (though integrated design may also be pursued without explicit aims of sustainability). The proposed paper describes ongoing research concerning alternatives to the currently common techniques for locating and displaying information in 3D building models in support of sense-making to promote collaborative and integrated design. These alternatives comprise on the one hand interactive geometric-content-based methods for search and classification of model objects ‚Äì as an alternative or complement to common assigned-attribute-based methods ‚Äì and on the other hand visual analytic techniques ‚Äì in contrast to existing, relatively static tabular and "physical" views ‚Äì which can help to increase the informativeness of the geometric data within the model, as well as the non-geometric data that is attached to geometric objects (e.g. as in the cases of BIM and various types of CAE performance simulations). Tests undertaken with architects and engineers in practice and academia to evaluate the proposed methods are also described. Finally conclusions are drawn regarding these methods‚Äô positive present performance and some of their shortcomings, as well as indicating directions for future research concerning the methods‚Äô refinement and extension to help 3D building models become more effective components of the design process than they are at present, both with respect to these models‚Äô present levels of complexity and especially with respect to their anticipated increasing complexity in future.

title	A Long-term Scope of Actions for Reconstructed Cultural Heritage: Maintaining a Virtual Archive of Nonexisting Synagogues
source	International Journal of Architectural Computing vol. 9 - no. 3, 285-302
summary	Reconstruction work on more than twenty synagogues in Vienna has been ongoing for more than a decade. The fact that these sacred buildings no longer exist is a pivotal aspect in this undertaking. Research revealed archived material, however, which served as reliable basis for the reconstruction work. The authors discuss details of the process of handling archival research as well as the decision-making process during reconstruction. The paper focuses on the possibilities and limits of this exploration and discusses the long-term options of handling 3D models, also in the light of continuous changes in the software environments used. The dissemination of results to a large audience and the appropriate illustration of spatial contexts is another aspect that has been explored. The publication of results in the form of a city guide is in line with the objective of conveying the reconstruction results to a large audience.

summary	The paper discusses the following problem: How can digital technology are integrated with urban composition teaching to provide a better understanding of the aesthetical and emotional aspects of the city? It argues for the current need for an integration of computer modelling and the approaches developed form the work of K. Lynch, G. Cullen, R. Krier, F. Ching. The paper is based on the experience in design studio teaching and an experiment completed with students. The exercise shows the students that different spatial organization may cause different emotions according to the treatment of space-defining elements. The paper presents the background and context as well as describes the experimental environment and the student work.

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	'GHShot': a collaborative and distributed visual version control for Grasshopper parametric programming

summary	When working with parametric models, architects typically focus on using rather structuring them (Woodbury, 2010). As a result, increasing design complexity typically means a convoluted parametric model, amplifying known problems: 'hard to understand, modify, share and reuse' (Smith 2007; Davis 2011). This practice is in contrast with conventional software-programming where programmers are known to meticulously document and structure their code with versioning tool. In this paper, we argue that versioning tools could help to manage parametric modelling complexity, as it has been showing with software counterparts. Four key features of version control: committing, differentiating, branching, and merging, and how they could be implemented in a parametric design practice are discussed. Initial user test sessions with 5 student designers using GHShot Grasshopper version control plugin (Cristie and Joyce 2018, 2017) revealed that the plugin is useful to record and overview design progression, share model, and provide a fallback mechanism.

title	Designing responsive architecture: Mediating analogue and digital modelling in the studio
doi	https://doi.org/10.52842/conf.caadria.2011.155
source	Proceedings of the 16th International Conference on Computer Aided Architectural Design Research in Asia / The University of Newcastle, Australia 27-29 April 2011, pp. 155-164
summary	Prototyping digitally responsive architecture requires that architects know how to program and design electronics. Normally they don’t. The challenge for teachers is to teach these skills whilst maintaining a focus on the design potentials of responsive architecture. One method is to teach students to use Input-Output-Process (IPO) diagrams and parametric modelling as pathways into the logic of responsive architecture. The paper discusses the work of students taught this way during a semester long elective. Our analysis shows that IPO diagrams lead to reactive architecture, which matches the current technical limitations of responsive architecture. We argue that mediating analogue and digital models is an essential aspect to successful responsive architecture.

title	Using domain specific languages in the Building Information Modelling workflow
doi	https://doi.org/10.52842/conf.caadria.2011.731
source	Proceedings of the 16th International Conference on Computer Aided Architectural Design Research in Asia / The University of Newcastle, Australia 27-29 April 2011, pp. 731-740
summary	The design of architecture, in practice, entails the collaboration of many disciplines each with their own set of tools and representations. Building Information Models aim to support interoperability between these disciplines. However current implementations require a lot of manual work involving translating parts from the various specialised descriptions to the common model format. Domain Specific Languages are a development from Information Technology that defines a mapping from the concepts used in one discipline to those used in another. In this paper, a workflow incorporating the movement between specialised languages and a central model is described. The central model is structured using the Industrial Foundation Classes (IFC). The motivation for elaborating on the interdisciplinary workflow is the desire to create a more iterative process without the need for the manual recreation of models. While it is difficult to have a description or language that contains all the information of all the disciplines, this research demonstrates how the IFC schema acts as a pivot not just between data sets, but also between concepts expressed in different representations thus giving from analysis to design.

title	Packing the “Chinese box”: A strategy to manage knowledge using architectural digital models
doi	https://doi.org/10.52842/conf.caadria.2011.717
source	Proceedings of the 16th International Conference on Computer Aided Architectural Design Research in Asia / The University of Newcastle, Australia 27-29 April 2011, pp. 717-726
summary	The architectural design activity has been transformed due to technological advances in building knowledge management. The research proposed is based on a three years long Ph.D. work on 3D models intended as graphical informative systems, layered according to the “Chinese box” paradigm and destined to professionals and researchers in architecture. The applied case study is referred to San Vitale’s church in Ravenna, Italy: the monument was investigated through nested digital models produced by different computer programs. Passing through evolutionary steps identified as synthesis, reduction and projection, the resulting archive lowered its Complication Ratio, a numerical value inspired by fractal’s auto-similarity, indicating a recursive modification in morphologies and contents. Models so conceived are qualified as progressive knowledge-based catalogues easily interchangeable and useful to understand how new or existing architectures work. As a result of this approach, representations obtained with surveys, historical chronicles, light analysis and acoustic simulations were composed following gradual refinements: technical data were collected running parallel to bibliographic research, enriching interactive virtual models sprung from a recursive criterion destined to increase the information enclosed into an undivided, lossless, digital archive.

title	De la Optimización Estructural Evolutiva al Diseño Paramétrico basado en desempeño; experiencias en plataformas integradas para estrategias de diseño multidisciplinares [From Evolutionary Structural Optimization to performance driven Parametric Design; experiences on integrated platforms for multidisciplinary design strategies]
source	SIGraDi 2011 [Proceedings of the 15th Iberoamerican Congress of Digital Graphics] Argentina - Santa Fe 16-18 November 2011, pp. 201-205
summary	This paper presents a research developed by a multidisciplinary team looking into the use of Topological Optimization and its integration to collaborative design platforms in early stages of design processes. The interest of the experience is focused on how Evolutionary Structural Optimization (ESO) models can be further integrated into parametric design software for the definition of adaptable components in response to environmental and architectural criteria. This research explores platforms and processes for the collaboration between software development, structural engineers and architects in early stages of design as a possibility to relate the potential of computational processes with the definition of design criteria involving architectural, structural and environmental parameters.
