summary	Technically-oriented architectural spaces today are getting complicated because the building contains a number of electronic facilities and complex structures. Furthermore, the advent of the ubiquitous environment enabled the building to provide various services to users and accelerated the importance of architectural visualization as problem-solving and communicating tools. It is recommended that architectural visualization has been more intuitive and effective to support the design decision and collaboration. In this manner, this paper intends to define the role of current architectural visualization with considerations of previous research and related works in the practical field and proposes the appropriate method of architectural visualization. Also, in order to evaluate our idea, we recommend a prototype system based on dynamic and semantic representation with the avatar. It is a kind of simulator for the design of ubiquitous smart space and can deliver to users the better comprehension in how technological oriented space will be constructed and utilized.

title	Automated Cost Analysis of Concept Design BIM Models
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. 403-418.
summary	AUTOMATED COST ANALYSIS OF CONCEPT DESIGN BIM MODELS Interoperability: BIM models and cost models This paper introduces the automated cost analysis developed for the General Services Administration (GSA) and the analysis results of a case study involving a concept design courthouse BIM model. The purpose of this study is to investigate interoperability issues related to integrating design and analysis tools; specifically BIM models and cost models. Previous efforts to generate cost estimates from BIM models have focused on developing two necessary but disjoint processes: 1) extracting accurate quantity take off data from BIM models, and 2) manipulating cost analysis results to provide informative feedback. Some recent efforts involve developing detailed definitions, enhanced IFC-based formats and in-house standards for assemblies that encompass building models (e.g. US Corps of Engineers). Some commercial applications enhance the level of detail associated to BIM objects with assembly descriptions to produce lightweight BIM models that can be used by different applications for various purposes (e.g. Autodesk for design review, Navisworks for scheduling, Innovaya for visual estimating, etc.). This study suggests the integration of design and analysis tools by means of managing all building data in one shared repository accessible to multiple domains in the AEC industry (Eastman, 1999; Eastman et al., 2008; authors, 2010). Our approach aims at providing an integrated platform that incorporates a quantity take off extraction method from IFC models, a cost analysis model, and a comprehensive cost reporting scheme, using the Solibri Model Checker (SMC) development environment. Approach As part of the effort to improve the performance of federal buildings, GSA evaluates concept design alternatives based on their compliance with specific requirements, including cost analysis. Two basic challenges emerge in the process of automating cost analysis for BIM models: 1) At this early concept design stage, only minimal information is available to produce a reliable analysis, such as space names and areas, and building gross area, 2) design alternatives share a lot of programmatic requirements such as location, functional spaces and other data. It is thus crucial to integrate other factors that contribute to substantial cost differences such as perimeter, and exterior wall and roof areas. These are extracted from BIM models using IFC data and input through XML into the Parametric Cost Engineering System (PACES, 2010) software to generate cost analysis reports. PACES uses this limited dataset at a conceptual stage and RSMeans (2010) data to infer cost assemblies at different levels of detail. Functionalities Cost model import module The cost model import module has three main functionalities: generating the input dataset necessary for the cost model, performing a semantic mapping between building type specific names and name aggregation structures in PACES known as functional space areas (FSAs), and managing cost data external to the BIM model, such as location and construction duration. The module computes building data such as footprint, gross area, perimeter, external wall and roof area and building space areas. This data is generated through SMC in the form of an XML file and imported into PACES. Reporting module The reporting module uses the cost report generated by PACES to develop a comprehensive report in the form of an excel spreadsheet. This report consists of a systems-elemental estimate that shows the main systems of the building in terms of UniFormat categories, escalation, markups, overhead and conditions, a UniFormat Level III report, and a cost breakdown that provides a summary of material, equipment, labor and total costs. Building parameters are integrated in the report to provide insight on the variations among design alternatives.

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	Spatial Augmented Reality for Architecture Designing and planning with and within existing buildings
source	International Journal of Architectural Computing vol. 6 - no. 1, pp. 41-58
summary	At present, more than half of all building activity in the German building sector is undertaken within existing built contexts. The development of a conceptual and technological basis for the digital support of design directly on site, within an existing building context is the focus of the research project "Spatial Augmented Reality for Architecture" (SAR). This paper describes the goals achieved in one aspect of the project: the sampling of colors and materials at a scale of 1:1 using Augmented Reality (AR) technologies. We present initial results from the project; the development of an ad-hoc visualization of interactive data on arbitrary surfaces in real-world indoor environments using a mobile hardware setup. With this, it was possible to project the color and material qualities of a design directly onto almost all surfaces within a geometrically corrected, existing building. Initially, a software prototype "Spatial Augmented Reality for Architecture-Colored Architecture" (SAR-CA) was developed and then assessed based on evaluation results from a user study.

title	Emerging Technologies in a Participatory Design Studio_between Carleton University and Pennsylvania State University
source	Proceedings of the 8th European Architectural Endoscopy Association Conference
summary	As a preliminary report on a proof-of-concept design studio conducted during the spring semester of 2007 between the Carleton Immersive Media Studio (CIMS) at Carleton University in Ottawa and the Immersive Environment Laboratory (IEL) at Pennsylvania State University, the paper first describes the implementation of this network-centric collaborative design platform. The report articulates the “staging” of the conditions of possibility for a dynamic interplay between technological mediation and the reality of making, then compares the use of high bandwidth technology with customized symmetrical toolsets in the tele-collaborative educational environment, versus commercial toolsets deployed over moderate bandwidth connections. In each setting, the collaborative environment is assessed according to issues encountered by students and design outcomes. The effectiveness of the digitally mediated collaborative studio is also gauged in terms of student reaction to the learning process via feedback surveys and questionnaires.

summary	The digital tools are most convenient technologies to realize distributed collaborative design environment on the web. A lot of practical design systems have been already developed with researches in the world. On these systems, the digital bulletin board and web-map technologies are generally used to support for group-discussing and exchanging design proposals via the web. But some of them are only possible to store design materials apart on the web and the peculiar interface is not well-optimized for architectural design activities. In this paper, we discuss to develop the collaborative design system simulated of our practical group-work methods. The APEX/VPB & MAP will realize the easy information management with interactive digital bulletin board and map-based interface. Finally, we will report the results of our experimental design studio using with APEX/VPB & MAP.

title	[SIN]uous: Developing a Pattern Fabricator Bridging between Visualization in the Digital and Fabrication in the Physical
source	CAADRIA 2008 [Proceedings of the 13th International Conference on Computer Aided Architectural Design Research in Asia] Chiang Mai (Thailand) 9-12 April 2008, pp. 452-458
doi	https://doi.org/10.52842/conf.caadria.2008.452
summary	We describe a domain-specific design tool capable of creating and fabricating complicated curvilinear patterns within the early stages of the design. This tool entitled “[SIN]uous” is a parametric design application that allows both the customization and fabrication of dynamic patterns created by the combination of SINE and COSINE functions. This tool allows designers and architects to design curvilinear patterns and manufacture schematic physical models of them in a short period of time, using rapid prototyping equipment such as a laser cutter. This tool consists of several modules, including a pattern maker, a fabricator, and a 3-D simulator. Using this tool, patterns are generated by manipulating variable parameters and fabricated according to the assembly sequence easily and quickly through algorithms by locating nodes of intersections. The end result is an exported computer file compatible with laser cutting technology. We expect that this design tool will facilitate the transition between the virtual and the physical, thus resulting in a better design product.

title	Dynamic (Shape) Grammars
source	CAADRIA 2008 [Proceedings of the 13th International Conference on Computer Aided Architectural Design Research in Asia] Chiang Mai (Thailand) 9-12 April 2008, pp. 22-28
doi	https://doi.org/10.52842/conf.caadria.2008.022
summary	The research presented in the paper explores the creation of custom shape grammars with animation tools, either as learning or educational tool or for the purposes of architectural design. Standard shape grammars contain an initial shape or design and one or more transformation rules. In a simple scenario the designer just applies the rules in the initial design or in a complicated scenario has to choose which rule to apply. Dynamic shape grammars on the other hand use animation tools to produce dynamic rules of transformation, or even dynamic – parametric initial shapes on which to apply the rules on. The dynamic state of the rules in our system allows the designer to change the rules during designing without having to abandon a core idea or concept. Furthermore the implementation with an animation tool allows the design system to be form-independent and express the underlying structure of an architectural idea with non-graphical connections like parent and child relationships, or other deformation rules. It can be shown that in a computation context dynamic shape grammars are actually groups of standard shape grammars where the grammars in the group share the classification of the transformation rules they contain. The system that we present allows the designer to change between the grammars in one group in a transparent way without expressing the grammar formally but by only manipulating simple objects inside the animation software package. This transparency focuses the effort of the user in simply design and keeping track of the formal declarations of shape grammars while the multiple dynamic grammars remove the obstacle of conforming to a single set of rules. The benefits of this effort can be especially seen in actual architectural design where the focus is in developing a concept idea and not strictly adhering to the rules.

summary	The aim of this paper is to explore how new technological opportunities affect approaches of designers during collaborative architectural design process. Which factors affect the communication and the quality of interaction? The study is based on two phases: the data input by the designer via devices to the computer environment and the transformation of data into design product in the software by scripting addition. Input devices that are used are 3D mouse, graphic tablet as a tangible interface and implementation of second mouse besides a standard mouse and keyboard. The potential usage of these interfaces in collaborative architectural design process is discussed and proposals are developed in 3ds max scripting environment.

doi	https://doi.org/10.52842/conf.acadia.2008.464
summary	MxR—pronounced “mixer”—is a Mixed/Augmented Reality system intended to support collaboration during early phases of architectural design. MxR allows an interdisciplinary group of practitioners and stakeholders to gather around a table, discuss and test different hypotheses, visualize results, simulate different physical systems, and generate simple forms. MxR is also a test-bed for collaborative interactions and demonstrates different configuration potentials, from exploration of individual alternatives to group discussion around a physical model. As a MR-VR transitional interface, MxR allows for movement along the reality-virtuality continuum, while employing a simple tangible user-interface and a MagicLens interaction technique.

title	Computing And Manipulation In Design - A Pedagogical Experience Using Symmetry
source	SIGraDi 2008 - [Proceedings of the 12th Iberoamerican Congress of Digital Graphics] La Habana - Cuba 1-5 December 2008
summary	The concept of symmetry has been usually restricted to bilateral symmetry, though in an extended sense it refers to any isometric transformation that maintains a certain shape invariant. Groups of operations such as translation, rotation, reflection and combinations of these originate patterns classified by modern mathematics as point groups, friezes and wallpapers (March and Steadman, 1974). This extended notion represents a tool for the recognition and reproduction of patterns, a primal aspect of the perception, comprehension and description of everything that we see. Another aspect of this process is the perception of shapes, primary and emergent. Primary shapes are the ones explicitly represented and emergent shapes are the ones implicit in the others (Gero and Yan, 1994). Some groups of shapes known as Semantic Shapes are especially meaningful in architecture, expressing visual features so as symmetry, rhythm, movement and balance. The extended understanding of the concept of symmetry might improve the development of cognitive abilities concerning the creation, recognition and meaning of forms and shapes, aspects of visual reasoning involved in the design process. This paper discusses the development of a pedagogical experience concerned with the application of the concept of symmetry in the creative generation of forms using computational tools and manipulation. The experience has been carried out since 1995 with 3rd year architectural design students. For the exploration of compositions based on symmetry operations with computational support we followed a method developed by Celani (2003) comprising the automatic generation and update of symmetry patterns using AutoCAD. The exercises with computational support were combined with other different exercises in each semester. The first approach combined the creation of two-dimensional patterns to their application and to their modeling into three-dimensions. The second approach combined the work with computational support with work with physical models and mirrors and the analysis of the created patterns. And the third approach combined the computational tasks with work with two-dimensional physical shapes and mirrors. The student’s work was analyzed under aspects such as Discretion/ Continuity –the creation of isolated groups of shapes or continuous overlapped patterns; Generation of Meta-Shapes –the emergence of new shapes from the geometrical relation between the generative shape and the structure of the symmetrical arrangement; Modes of Representation –the visual aspects of the generative shape such as color and shading; Visual Reasoning –the derivation of 3D compositions from 2D patterns by their progressive analysis and recognition; Conscious Interaction –the simultaneous creation and analysis of symmetry compositions, whether with computational support or with physical shapes and mirrors. The combined work with computational support and with physical models and mirrors enhanced the students understanding on the extended concept of symmetry. The conscious creation and analysis of the patterns also stimulated the student’s understanding over the different semantic possibilities involved in the exploration of forms and shapes in two or three dimensions. The method allowed the development of both syntactic and semantic aspects of visual reasoning, enhancing the students’ visual repertoire. This constitutes an important strategy in the building of the cognitive abilities used in the architectural design process.

title	Integrated Design and Building System for the Provision of Customized Housing: the Case of Post-Earthquake Haiti
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. 247-264.
summary	The paper proposes integrated design and building systems for the provision of sustainable customized housing. It advances previous work by applying a methodology to generate these systems from vernacular precedents. The methodology is based on the use of shape grammars to derive and encode a contemporary system from the precedents. The combined set of rules can be applied to generate housing solutions tailored to specific user and site contexts. The provision of housing to shelter the population affected by the 2010 Haiti earthquake illustrates the application of the methodology. A computer implementation is currently under development in C# using the BIM platform provided by Revit. The world experiences a sharp increase in population and a strong urbanization process. These phenomena call for the development of effective means to solve the resulting housing deficit. The response of the informal sector to the problem, which relies mainly on handcrafted processes, has resulted in an increase of urban slums in many of the big cities, which lack sanitary and spatial conditions. The formal sector has produced monotonous environments based on the idea of mass production that one size fits all, which fails to meet individual and cultural needs. We propose an alternative approach in which mass customization is used to produce planed environments that possess qualities found in historical settlements. Mass customization, a new paradigm emerging due to the technological developments of the last decades, combines the economy of scale of mass production and the aesthetics and functional qualities of customization. Mass customization of housing is defined as the provision of houses that respond to the context in which they are built. The conceptual model for the mass customization of housing used departs from the idea of a housing type, which is the combined result of three systems (Habraken, 1988) -- spatial, building system, and stylistic -- and it includes a design system, a production system, and a computer system (Duarte, 2001). In previous work, this conceptual model was tested by developing a computer system for existing design and building systems (Benr__s and Duarte, 2009). The current work advances it by developing new and original design, building, and computer systems for a particular context. The urgent need to build fast in the aftermath of catastrophes quite often overrides any cultural concerns. As a result, the shelters provided in such circumstances are indistinct and impersonal. However, taking individual and cultural aspects into account might lead to a better identification of the population with their new environment, thereby minimizing the rupture caused in their lives. As the methodology to develop new housing systems is based on the idea of architectural precedents, choosing existing vernacular housing as a precedent permits the incorporation of cultural aspects and facilitates an identification of people with the new housing. In the Haiti case study, we chose as a precedent a housetype called ‚Äúgingerbread houses‚Äù, which includes a wide range of houses from wealthy to very humble ones. Although the proposed design system was inspired by these houses, it was decided to adopt a contemporary take. The methodology to devise the new type was based on two ideas: precedents and transformations in design. In architecture, the use of precedents provides designers with typical solutions for particular problems and it constitutes a departing point for a new design. In our case, the precedent is an existing housetype. It has been shown (Duarte, 2001) that a particular housetype can be encoded by a shape grammar (Stiny, 1980) forming a design system. Studies in shape grammars have shown that the evolution of one style into another can be described as the transformation of one shape grammar into another (Knight, 1994). The used methodology departs takes off from these ideas and it comprises the following steps (Duarte, 2008): (1) Selection of precedents, (2) Derivation of an archetype; (3) Listing of rules; (4) Derivation of designs; (5) Cataloguing of solutions; (6) Derivation of tailored solution.

summary	While conventional information displays are still effective, a lack of integration between descriptive and contextual information means they cannot be used independently of additional external information. New digital systems such as Google Maps are increasing in popularity. Unfortunately these present some limitations in terms of understanding both route and survey information, and in particular navigation and orientation, such as intuitively understanding a plan view no matter which way one is facing, so visitors can quickly and intuitively learn how to get to specific buildings or to specific facilities. Digital systems may also alienate older and non computer literate users; and they display contextual information inside an interface which limits the possible range of interaction methods offered by physical interaction. Our solution was to create a 3D physical model that one could spin, which would in turn display digital panoramas that spun in rotational alignment with the physical city model. Further, the user could place category tokens in intersections of the city model, which would bring up digital panoramas on the screen and highlight facilities linked to the category chosen. Rotating the token would also rotate the digital panorama.

summary	Recently, urban planning has largely placed the user at street as the centre of infrastructural design, with significant implications for the perceived attractiveness of user environments. The urban designers faced with the task of designing such spaces, needs a tool that will allow different designs to be compared in terms of their attractiveness as well as their effectiveness. Therefore, this paper applies the selective attention theory and establishes a pedestrian behavior model that embeds the behavior-based rules and attributes of an agent. We call this simulation platform to be an agent-based street simulator (ABSS). Through experiments and verifications on cases of real-life urban streets, the system and its applications, and major findings are reported.

title	O túnel de vento – um exercício de projeto baseado em técnicas de animação [The wind tunnel - an exercise in design based on techniques of animation]
source	SIGraDi 2008 - [Proceedings of the 12th Iberoamerican Congress of Digital Graphics] La Habana - Cuba 1-5 December 2008
summary	The objective of the present research was to study the use of animation techniques as a tool for the design process. The study started with a literature review about the different possible applications of animation techniques in architectural design. Four main categories of applications were found: (1) space representation and “walk through”, (2) simulation of articulated elements and kinetic structures, (3) visualization and analysis of functional aspects of the buildings, such as circulation and fire escape, and finally (4) the generation of novel shapes. The second part of the research consisted of a design exercise in which animation techniques were used to generate a shape. For this purpose a wind simulator was used in 3DMAX. Next, Paracloud software was used to automatically generate a rib structure that allowed to produce a scale model of the shape with a laser cutter.

title	Constraint-Based Design in Participatory Housing Planning
source	International Journal of Architectural Computing vol. 6 - no. 1, pp. 97-117
summary	We introduce some novel ideas for a constraint-based design strategy to support participatory housing planning processes in Latin America. The following lines intend to open the discussion on the requirements and effect of the computer implementation of a constraint satisfaction approach to solve elementary design problems in architectural practice. The case study applies to the building massing design problem posed by the Chilean urban regulatory framework that addresses single-family affordable houses. Two different implementation criteria are being tested in an ongoing series of trials providing further considerations. One prototype uses MAXON's CINEMA4D XPRESSO® visual scripting environment to set up a semi-automated design environment which allows users to edit one feature-based 3D model of massing alternative at a time. The other prototype uses ILOG's OPL STUDIO® constraint programming environment to achieve fully automated search and 2D visualization of all possible solution alternatives to separate subdomains of the building massing design problem.

summary	Since Hugh Ferris in 1922 started with a series of massing studies the visualization of zoning planning began to be a topic for architects. Setbacks, plot area ratio, maximum building height, and other important attributes must be handled by the architect to fulfill the law, the needs of the clients and his own inspiration. This paper presents the problem of envelope design for high-rise isolated housing buildings, as well as a new Decision Support Systems tool based on the platform of a BIM software, that allows to simulate several options for building envelope according to the parameters required by the city Zoning Planning. These options deliver reliable data and geometry, to be analyzed in real time for the architects, engineers, builders, government and the client in the early stages of the building’s design.

summary	This paper can be viewed as the continued development of a research project presented at last year’s eCAADe. The project focused on the potential and possibilities of cooperation among architects, investors with concrete building projects, and researchers at the university level working on generative design and parametric construction. After having spent several years of research on design techniques in a purely academic setting at the university we see, contrary to our fears, that reality and the integration of concrete factors such as budget, time management, etc. does not diminish but rather improves the quality of our work. This work is not primarily concerned with the development of a new architectural language but the intelligent use of modern computer technology based on digitized planning processes defined as ‘complex building design’. Designs developed in this manner can be distinguished by certain characteristics, the evaluation of which is a point critically discussed in the following paper.

title	Anaglyph Representation as Medium for Spatial Design

summary	The paper discusses the use and possible applications of stereoscopic projection and anaglyph representation for the design-process and visualization of architectural spaces and three-dimensional objects. As the topic of stereoscopic vision is quiet broad and has a long tradition in various fields (photography, art, virtual reality) the paper focuses on the implementation of anaglyph representation in 3D-Modeling-Software as a tool to support spatial perception within the design process. Against this background and based on a test-series with 113 students the benefits and conditions of spatial perception, vision and sense using anaglyph representation are examined.

title	Creation of an Evolutive Conceptual Know-how Framework for Integrative Building 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. 435-450.
summary	Low productivity of the building sector today is attributed to the fragmentation of tasks, disciplines and responsibilities, as well as to the resistance to adopt integrative work processes and digital means. The increased complexity of architectural projects and the aroused social consciousness for sustainable environment calls for integrative design collaboration. Thus, there is need for a Conceptual Framework combining work processes, technological means and policy aspects. According to the literature, integrative multidisciplinary design is a strategy resulting in high performance buildings nurturing sustainable way of living (Reed et al. 2009, Krygiel & Nies 2008). Responding to the increased technological complexity of our built environment, as well as to the objective of meeting multiple criteria of quality, both necessitating multidisciplinary collaboration during design, Building Information Modeling (BIM) is seen as a powerful means for fostering quality, augmenting productivity and decreasing loss in construction. Based on recent research, we can propose that a sustainable building can be designed through an integrative design process (IDP) which is best supported by BIM. However, our ongoing research program and consultations with advanced practitioners underscore a number of limitations. For example, a large portion of the interviewed professionals and construction stakeholders do not necessarily see a link between sustainable building, integrative design process and BIM, while in our opinion, their joint use augments the power of each of these approaches taken separately. Thus, there is an urgent necessity for the definition of an IDP-BIM framework, which could guide the building industry to sustainable results and better productivity. This paper defines such a framework, whose theoretical background lays on studies in social learning (activity theory and situated action theories). These theories suggest that learning and knowledge generation occurs mainly within a social process defined as an activity. This corresponds to the context in which the IDP-BIM framework will be used, its final objective being the transformation of building design practices. The proposed IDP-BIM framework is based on previous research and developments. Thus, firstly, IDP process was well formalized in the Roadmap for the Integrated Design Process‚ (Reed et al.) which is widely used as a guideline for collaborative integrative design by innovating practices in USA and Canada. Secondly, the National Building Information Modeling Standard (NBIMS) of the USA is putting an enormous effort in creating a BIM standard, Succar (2008) recently proposed a conceptual framework for BIM, but BIM ontology is still under development (Gursel et al 2009). Thirdly, an iterative design process bound to gating reviews (inspired from software development processes) was found to be successful in the context of multidisciplinary design studios (reported in our previous papers). The feedback from this study allowed for modifications and adjustments included in the present proposal. The gating process assures the good quality of the project and its compliance to the client's requirements. The challenge of this research is to map the above mentioned approaches, processes and technologies into the design process, thus creating an integrated framework supporting and nurturing sustainable design. The IDP-BIM framework can be represented by a multidimensional matrix linked to a semantic network knowledge database: - the axes of the matrix being the project timeline, the design process actors and building stakeholders (architect, engineers, client, contractor, environmental biologist, etc.), or different aspects of building performance (environmental, functional, social, interior environment quality, cost, etc.); and - the knowledge database providing multiple layers of semantic support in terms of process, domain knowledge, technology and workflow at a given moment of the project and for a given actor or building aspect. The IDP-BIM framework is created as an evolutive digital environment for know-how and will have an established protocol for regular updates. The paper will firstly present the state of the art in IDP and BIM. Secondly, it will expose the methodology used for the definition of the Framework, followed by a description of its structure, contents and digital implementation. Then, some scenarios for the use of the Framework will be shown as validation.
