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	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	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	Preparing a multimedia-based gallery for institute of higher learning: A case study of Malaysian experience
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. 305-316
summary	While the majority of medium and small sized institutions still rely on their physical or traditional content, it has been observed a pre-disposition usually by major, recently founded or contemporary art institutions to display net-based projects (Buiani, 2001) and to some extent established as a permanent display. This changing of exhibitions has penetrated in many Asian galleries and as a result many schools trying to re-position and present in such a way that it can be easily changed and adapted to host multimedia, Internet, interactive and computer-based content. This funded research project investigates the functions of gallery in IHL in Malaysia. A triangulated study was conducted to understand the potentials and issues faced by galleries in public and private universities focusing on design schools that include art and design, and architecture. This research starts with the understanding of gallery design theories. It is then followed by a qualitative method survey to all galleries in the IHL. This research continues with an in depth study and a survey on Electronic Gallery (e-Gallery), Faculty of Creative Multimedia (FCM), Multimedia University (MMU) to understand between the theories and design ideas. A set of questionnaires was developed based on Mathews (1991) and Stewart’s (2002) principles and guidelines on research methods and distributed to visitors throughout a period of time consisting of open-ended, close-ended, Likert Summated Rating Scale and Multiple-choice. This involved a controlled group of visitors comprises students and staff of the faculty. The results of these studies will be used as a reference to further conduct a wider scope of galleries worldwide towards designing a multimedia-based gallery framework for Institute of Higher Learning.

title	Adaptation as a Framework for Reconsidering High-Performance Residential Design: A Case Study
doi	https://doi.org/10.52842/conf.acadia.2013.109
source	ACADIA 13: Adaptive Architecture [Proceedings of the 33rd Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-1-926724-22-5] Cambridge 24-26 October, 2013), pp. 109-118
summary	This paper outlines an approach to adaptive residential design explored through recent research and an executed prototype, the North House project (2007-2009), undertaken through an interdisciplinary collaboration of researchers and students from the University of Waterloo, Ryerson University and Simon Fraser University in concert with professional and industry partners. This project aimed to develop a framework for the delivery of adaptive detached residential buildings capable of net-zero energy performance in the temperate climate zone, or the near north. Within this project, the term “adaptive” is developed across several tracts of conceptualization and execution including site and climatically derived models for building material composition and envelope ratios, environmentally-responsive kinetic envelope components, intelligent HVAC controls and interactive interface design aimed at producing co-evolutionary behaviors between building systems and inhabitants. A provisional definition of adaptive architecture is outlined to address this range of considerations that calls into question the stable image of domestic architecture and its relationship to energy and contemporary assumptions regarding sustainable design. This paper also outlines computational approaches to design optimization, distributed building systems integration and the human-controls interfaces applicable to the home’s ecology of physical and information technologies.

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	Architectural eLearning: An inquiry into the fuzzy boundaries that separate education and instruction [Architectural eLearning. Una indagación sobre los límites borrosos que separan la educación y la instrucción]
source	SIGraDi 2007 - [Proceedings of the 11th Iberoamerican Congress of Digital Graphics] México D.F. - México 23-25 October 2007, pp. 155-158
summary	This communication is based on the development of a new subject to be imparted in collaboration with three Departments (Visual Communication, Projects and Construction) at the School of Architecture of Barcelona. It is a work that has been financed with a special grant from our university, aimed at the development of new teaching modalities and, in particular, of those that would develop the use of new technologies, collaboration among university departments and eLearning. The aim of the communication is twofold. First, to present some results that we consider valuable in themselves, as much for the techniques as for the methodology that we have used. Second, to propitiate a debate on the new situation that the teaching of architecture is moving to, due to the advance of a series of instruction methods where the methodological organization, the storing of informative material and the preparation of autonomous interactive systems, open more and more effective roads of learning but that, at the same time, point towards a new educational structure that fits badly within the traditional structures in which we have still to work daily. Regarding the first point, the main aspects to highlight are: a) the development of a selflearning system by means of a very complete series of tutorials that allow a gradual acquisition, depending on the necessities or interests of each student, of geometric modeling, parametric design, visual simulation and interactive animation techniques, b) the development of a system of general information supply and on line comments and corrections. Regarding the second point, a provisional theoretical framework has been elaborated based on the consideration of the ubiquitous visual communication media as misleading mediators of a personal relationship. This theoretical frame has been tested by a few experiences carried out with the collaboration of students implied in the project. The general conclusion is that both challenges must be faced at the same time: new educational technologies must be analysed and integrated in our curricula and a new theoretical framework, able to clarify the difference between instruction and education, must be developed in parallel with those technologies.

title	A Theoretical Framework for the Implementation of Building User’s Lifestyle in nD CAD System
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. 595-606
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	Management system for a Virtual Cooperative Project
doi	https://doi.org/10.52842/conf.ecaade.2007.125

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

summary	Prototype manufacturing as an educational tool has been very successful at the college level in architecture and engineering design. This paper discusses an innovative inquiry-based learning approach rather than the problem-based learning models commonly utilized by other similar programs. For example, several research-funded technology projects (e.g., Cappelleri et al. 2007) look at involving students in problembased learning exercises (e.g., building robots); however, these exercises (while providing valuable experiences) have predetermined outcomes ingrained by the teachers, the project structure, and the components used to construct the devices. Therefore, inquisitive and creative problem solving is limited to the “kit-of-parts” in their approach to solving the problem. The inquiry-based CADCAM pedagogy model is more concerned with the process of solving a problem through the vehicle of prototyping than with the specificity of the design project itself. This approach has great potential. First, the need to solve the problem drives learning on multiple levels, integrating interdisciplinary ideas into the problem and solution. Second, the problem interlocks disciplines through inquiry knowledge building in team exercises. Finally, it encourages diversity and flexibility by allowing students to look at problems from multiples perspectives and points of view.

title	BIM as a Viable Collaborative Working Tool: A Case Study
doi	https://doi.org/10.52842/conf.caadria.2007.x.l1j
source	CAADRIA 2007 [Proceedings of the 12th International Conference on Computer Aided Architectural Design Research in Asia] Nanjing (China) 19-21 April 2007
summary	For the majority of design practices in the construction industry the use of CAD systems have been used to merely automate hand drafting (Cohen 2003). This is the traditional way of working that has changed very little since the introduction of commercial CAD systems. These practices as means of communication are being replaced by a virtual building model environment which encapsulates all of the information for an entire construction project and thereby enables computer-supported co-operative working practices. (Newton 2003) This study aims to determine whether Building Information Modelling (BIM) can, and whether it will, replace traditional communication media as the standard in the industry for computersupported co-operative working practices in the Architecture Engineering and construction (AEC) sector. The bulk of the research comprises an extensive literature review looking at the principal reasons behind the development of BIM, the potential advantages and drawbacks of the technology, and the barriers and obstacles which inhibit its adoption as a means of computer-supported co-operative working. The findings of the study have been validated and analysed against current practice in the field through a live case study analysis of the on-going Heathrow airport Terminal 5 Project in London (UK). The Terminal 5 case study demonstrates that present software tools, although usable, still present significant implicit technical constraints to wider implementation among Small and Medium Enterprises (SMEs). The case study has also shown that in practice, the success of BIM depends just as much on the working practices and ethos of participants in the project chain as it does on the capabilities of the software itself, in particular the willingness of practitioners to change traditional working practices. The case study has shown that the present investment, in terms of time, cost, and effort required to implementing the technology means that BIM is unlikely to be adopted on small simple projects where conventional CAD is still adequate. It also highlighted that BIM tools currently available are not yet adequately developed to satisfy the requirements of the many procurement and especially contractual arrangements which presently exist and many firms will be frightened off by the unresolved legal issues which may arise from implementing BIM in their practices.

title	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.

summary	Novel conceptions of structures consisting of spatial formations of struts and cables present a uniquely defined morphology and structural performance, and offer opportunities for innovative applications in building design. A common feature of these structures is that their spatial geometry is not “a priori” given. This paper is focused on a specific type of cable-strut structure that occurs from the assembly of self tensioned cable-strut modules The spatial configuration of these structures is very complex and necessitated the development of elaborate geometric algorithms that permit the generation of their formal geometry in a virtual 3D environment. To facilitate both the design and the construction of such structures, a spatial visualization system, which integrates a) algorithms for initial form generation, b) geometric parameters that simulate construction stiffening processes, and c) appropriate structural analysis methods, has been developed. The structural organization and parts of this system are presented in this paper. The system renders feasible the exploration of alternate geometries with various levels of pre-stress and displays initial and final configuration of the structure. It also allows for structural analysis data visualization. Examples of projects designed with the assistance of this system are included and discussed.

title	Integration of 3D Tool with Environmental Impact Assessment (3D EIA)
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. 51-66
summary	Environmental Impact Assessment (EIA) tools have been available for some years now and their function is predominantly to predict and identify the environmental impact of building projects. However EIA analysis is often done after the completion of the project or building and when it is too late to influence the design, materials or components to be used. Also, more than 80% of the design decisions that influence the whole life cycle of a building are made at the initial design phase. EIA does not receive the required attention. A new approach is suggested in this research to ensure that designers, clients and stakeholders have all of the relevant information needed at the outline design stage for the assessment of cost and environmental impact. The idea is that building owners and users will have the opportunity to minimise their operating costs from ‘cradle to cradle’. As energy resources reduce over the next few decades, the value of this research will increase and it is possible to foresee government legislation which drives building construction in this direction. By making environmental impact analysis readily linked to 3D products at the very early stage of the design process, the value of 3D technology will be enhanced significantly resulting in more use of the technology in the construction process. In this context, the objective of this paper is to introduce and explore approaches for developing integrated 3D- EIA, LCA (Life Cycle Analysis) and LCCA (Life Cycle Cost Analysis) and VR (Virtual Reality) tools and develop trade-off analysis to assist in the decision making process. To demonstrate initial results, a pilot case study in the UK is being developed.

summary	The publicly and privately funded national R&D program ‘Digital Construction’ was initiated in 2003 in order to establish a common platform for interchanging digital information and to stimulate digital integration in the Danish building industry. This paper explores the relation between visions, strategies and tools formulated in the ‘Digital Construction’ program, and the first experiences made from implementing the 3D work method part of the program in an ongoing building project. The discussions in the paper are placed in the complex field between choosing strategies for integrating information and communication technologies on national level, and the effects of these strategies on real life building projects.

title	Innovative CNC Timber Framing - Technology and Cultural Expression
source	International Journal of Architectural Computing vol. 5 - no. 3, pp. 469-486
summary	he design-build project for the outdoor theater roof structure at the UBC Malcolm Knapp Research Forest at Maple Ridge, British Columbia, explores technical, spatial, and cultural aspects of CNC wood fabrication. References for the project are technological innovation and formal expression of contemporary wood structures. The roof project illustrates how spatial concepts are informed by the logic of fabrication and methods of assembly. A reciprocal relationship between technology, space, and locale suggests that the introduction of new technology coincides with new spatial concepts. Innovative design in this project is defined as work that resonates at the intersection of the fields of technology, material science, manufacturing processes, and techniques of assembly that constitute the expanded context that projects need to engage. It is through collaborative design research on CNC wood fabrication technologies that common design and building practice is put into question, and boundaries are explored and expanded.

title	Early Architectural Design and BIM
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. 291-302
summary	This paper examines the meaning of information and communication technology (ICT) for architectural design in early design project phases, with a particular interest in building information modelling (BIM). Contemporary digital design environment, research context and objectives are first clarified, followed by the presentation and analysis of a few BIM-related projects. A key finding is that the architectural working environment, the design methods and the designer's roles have changed in the contemporary project context. Furthermore, other methods and tools are needed in addition to BIM in the early project phases, because it can not solve all required design aspects.

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 in 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 in 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 this as prototypes. This paper describes the goals of the “Spatial Augmented Reality for Architecture” project and discusses possible fields of application for SAR for supporting the design process in existing buildings from a user’s perspective. This paper presents the initial results of the project, the development of a cave-like hardware and software concept called “low-cost projection in room corners” and the description of the core concept based on a client-server architecture. The project is funded by the “German Research Foundation (DFG)”.

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)”.
