title	A Generative Urban Grammar for Portuguese Colonial Cities, During the Sixteenth to Eighteenth Centuries: Towards a Tool for Urban Design
doi	https://doi.org/10.52842/conf.ecaade.2009.585
source	Computation: The New Realm of Architectural Design [27th eCAADe Conference Proceedings / ISBN 978-0-9541183-8-9] Istanbul (Turkey) 16-19 September 2009, pp. 585-592
summary	This paper main goal is to depict the generative principles of 16th -18th century Portuguese colonial urban design described from its Pythagorean-Euclidean geometrical genesis and correspondent logical rules and operations. These origins were found in Portuguese compendiums and treaties on practical geometry, architectural and military engineering from the sixteenth through the eighteenth century. The study attempts to show that rigorous operative geometrical discourse is inseparable from social knowledge, whereby form is the operative result of abstract mental processes and logical visual reasoning associated to ideas of growth and reproduction of order.

title	Monitoring urban design through generative design support tools: a generative grammar for Praia
source	Proceedings of 15 Congresso da APDR, Cidade da Praia, Cabo Verde.
summary	Abstract Urban planning and design has a considerable impact on the economic performance of cities and regions. It is a complex process that extends for a long period and involves many participants. The lack of integrated tools to support this process hampers the ability to maximize the response of plans to contextual conditions while using the least resources. This paper describes research that aims to develop such a tool, integrating formulation, generation, and evaluation capabilities. It is focused on the generation module which relies on the encoding of Urban Induction Patterns (UIP) using shape grammars. A grammar for the extension plan of the city of Praia is presented as one of the case studies used to support UIP definition and illustrate its application. The paper also discusses how the proposed tool can be used for developing and monitoring urban plans.

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.

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	Beyond Representation: Real Time Form Finding of Tensegrity Structures with 3d ‘Compressed’ Components
doi	https://doi.org/10.52842/conf.ecaade.2009.021
source	Computation: The New Realm of Architectural Design [27th eCAADe Conference Proceedings / ISBN 978-0-9541183-8-9] Istanbul (Turkey) 16-19 September 2009, pp. 21-30
summary	Tensegrity structures are of interest to architecture and engineering as a practical means to explore lightweight and rapidly deployable modular structures that have a high degree of geometric freedom and formal potency. The notion of tensegrity structures with 3D ‘compressed’ components is introduced and their feasibility is demonstrated through selected physical models. Attempts to further explore the architectural potential of tensegrity structures within a computational environment have proven difficult, as they are statically indeterminate and require form finding procedures to “find a geometry compatible with a self-stress state” (Motro 2002). An overview of tensegrity ‘capable’ software that can be used for architectural design is followed by a discussion that introduces an additional computational method based on particle-spring systems. This approach enables real time manipulation of tensegrity networks. Two projects that utilize this unique tool are described.

title	Computational Fluid Dynamics in Building Design Practice
doi	https://doi.org/10.52842/conf.acadia.2020.1.574
source	ACADIA 2020: Distributed Proximities / Volume I: Technical Papers [Proceedings of the 40th Annual Conference of the Association of Computer Aided Design in Architecture (ACADIA) ISBN 978-0-578-95213-0]. Online and Global. 24-30 October 2020. edited by B. Slocum, V. Ago, S. Doyle, A. Marcus, M. Yablonina, and M. del Campo. 574-583.
summary	This paper provides a state-of-the-art of computational fluid dynamics (CFD) in the building industry. Two methods were used to find this new knowledge: a series of interviews with leading architecture, engineering, and software professionals; and a series of tests in which CFD software was evaluated using comparable criteria. The paper reports findings in technology, workflows, projects, current unmet needs, and future directions. In buildings, airflow is fundamental for heating and cooling, as well as occupant comfort and productivity. Despite its importance, the design of airflow systems is outside the realm of much of architectural design practice; but with advances in digital tools, it is now possible for architects to integrate air flow into their building design workflows (Peters and Peters 2018). As Chen (2009) states, “In order to regulate the indoor air parameters, it is essential to have suitable tools to predict ventilation performance in buildings.” By enabling scientific data to be conveyed in a visual process that provides useful analytical information to designers (Hartog and Koutamanis 2000), computer performance simulations have opened up new territories for design “by introducing environments in which we can manipulate and observe” (Kaijima et al. 2013). Beyond comfort and productivity, in recent months it has emerged that air flow may also be a matter of life and death. With the current global pandemic of SARS-CoV-2, it is indoor environments where infections most often happen (Qian et al. 2020). To design architecture in a post-COVID-19 environment will require an in-depth understanding of how air flows through space.

source	SIGraDi 2009 - Proceedings of the 13th Congress of the Iberoamerican Society of Digital Graphics, Sao Paulo, Brazil, November 16-18, 2009
summary	The knowledge of latest technology that allows the development of competitive products in reduced times is crucial to guarantee a sustainable growth of the national industry. This work presents the development of a computational system for the Virtual Design of products, the VirtusCADE, which is a CAD/CAE interactive software (Computer Aided Design/Computer Aided Engineering). The VirtusCADE includes 3D geometric modeling of surfaces and solids and mesh generation. The system uses the parametric modeling of surfaces, including algorithms for determination of intersection between surfaces and for triangular mesh generation in trimmed parametric surfaces. The graphical interface is interactive and allows the direct real time manipulation of objects (lines, surfaces and solids) in 3D using the OpenGL technology. The system prioritizes the usability, implementing several graphic tools that facilitate the manipulation in 3D. The VirtusCADE contemplates the structural simulation through the Finite Element Method. The code architecture is based on oriented object programming, which allows great scaling capability for the implementation of new tools. This project has great applicability in numerical simulation of physical phenomena, such structural analysis of buildings, vehicles parts, with impact in the industries of civil construction, metal-mechanics, aerospatial, naval and automotive.

title	Digital Technologies in Built Environment – An Overview
source	Fifth International Conference on Construciton in the 21st Century, Collaboration and Integration in Engineering, Management and Technology, May 20-22, 2009, Istanbul, Turkey.
summary	Abstract: Digital technologies are influencing the way we live. It is also shaping the way we design, construct, and manage the built environment around us. From collaborating design and construction ideas to creating the actual design to communicating onsite to training construction workers on health and safety issues there are different levels of involvement of the information and telecommunication technologies in the construction industry. Use of these diverse digital technologies is also spread through to the manufacturing building materials, public planning, and inspection process. The aim of the study is to offer a structured overview, which encapsulates these digital technologies that are being used and can be used in the AEC and property professionals. This study will also explore how these technologies can be introduced to the future professionals who will be the part of this digital practice. The study considers the need for a seamless approach to integrate digital technologies in built environment education and industry where blend of theoretical understanding of the subject matter and technical competence is required.

title	A Syncretization Of Architecture, Engineering And Science:The use of CAD technology as a pedagogical tool in the teaching of environmentally sustainable design
source	T. Tidafi and T. Dorta (eds) Joining Languages Cultures and Visions: CAADFutures 2009 CD-Rom
summary	Energy consumption in buildings is responsible for about 40% of Australia’s greenhouse gas emissions. It is quite feasible that the energy consumption in buildings can be halved, but energy performance analysis must be integral to the entire design process. This imperative has led the authors to propose that architecture, engineering and science should be syncretized in the design process. This syncretization shares some features of the rhizomatic approach introduced by Deleuze and Guattari (2007). In rhizomatic systems all points can be, and should be connected. A rhizome can be considered as a space that develops, not from a point but from milieux. In the expansion of a rhizome, elements of the system do not follow tracings of other elements but they form a map of new vistas. Likewise, a syncretic approach is oblivious to the traditional boundaries between architecture, engineering and science. Syncretization has the potential to enrich the intellectual lives of architects, scientists and engineers, and it would have profoundly beneficial performative benefits.

summary	In a world where sustainability, ecology, collaboration and performance are common concerns, “joining” is a keyword, expressing the idea of an integration of knowledge, efforts and processes aimed at a better future. The CAADFutures 2009 conference thus intends to join professional and scientific reflections, with the notable input of new disciplines that are also concerned with digital design, such as industrial design and civil engineering. As a result, a vivid dialogue is established between different cultural approaches, computational methods and philosophical positions. The field of computer-aided design is faced with many challenges. CAADFutures 2009 addresses the search for new paradigms for sustainable design, the issues derived from the “digital thinking” embedded in current CAD systems as opposed to the needed “design thinking”, and many more pressing questions such as those of heritage, advanced geometry and parametric design, CAD education, virtual environments, interaction and new technologies, simulation, building performance, rapid prototyping, management, collaboration and ideation.

summary	Recently, many cities in Japan and in other developed nations face problems such as decadence of downtown areas, aged society with a fewer number of children, dependence on automobile transport, etc. And redesign of public transportation services (e.g. tram) is thought to be one of the solutions for these problems. The introduction of LRT is investigated in various places, however, when a public traffic system like LRT is introduced, it is necessary to consider not only the transportation oriented aspects, but also landscapes and plans for a future sustainable city. Therefore, city planners are required to promote workshop-type in the design process to deal with citizens, companies, NPOs, etc. In this research, both components of the VR system for LRT projects and the system that enables the examination from various aspects of traffic, landscapes, city planning, etc., were studied.

source	SIGraDi 2009 - Proceedings of the 13th Congress of the Iberoamerican Society of Digital Graphics, Sao Paulo, Brazil, November 16-18, 2009
summary	This paper presents a distributed simulation system for urban scenarios where infrastructure anomalies are common, such as those present in Latin-American cities. A microscopic-based model has been developed in order to represent the behavioural characteristics of the different mobility actors in a discrete lattice. The visualization component allows an interactive and immersive experience of the simulation results, providing a detailed point of view (focus) in the global environment (context). It is possible to empower the users’ interaction through devices for control and navigation of the data visualization.

summary	In recent years a number of projects have been emerged, in which the new possibilities of the computer as a design tool, have been used. Through the digital chain from design to manufacturing the efficiency has increased and allows the implementation of complex architectural structures. With all these new opportunities, also new challenges arise in the teaching and the educational concepts. The paper describes the detailed course concept and the didactic strategy using the example of a parametric designed roof structure, we designed, planed and build up in scale 1:1 within the main course. „Wendepunkt\|e im Bauen“ (Turning point\|s of building) is the name of an exhibition at the “Pinakothek der Moderne” in Spring 2010. In addition to contributions of the industrialization in the building industry from 1850 to the present day, the exhibition also serves as a platform, to demonstrate new possibilities of computer-aided parametric design and the closely related computer aided manufacturing (CAM). In this context, we took the chance to build a sculpture in Scale 1:1 to show the potential of a constant digital workflow and the digital fabrication. Through the digital chain from design to manufacturing, the efficiency has been increased by the computer and allows the implementation of new complex architectural structures. But the efficiency of the high-degree-automation through the use of computerized machines usually ends in the production of the components. Because this coincidence of the elements in the assembly often proves cost and time, the aim of the project was to optimize both, the production of components and their assembly as well. As part of the wintercourse 2009/2010 different aspects of automation have been reviewed and new solutions have been analyzed. Together with 15 students of the Faculty of Architecture the complete digital chain started with the first design ideas, about parametric programming through production and assembly had been researched, implemented and brought to reality. In the first steps, the students had to learn about the potential, but also about the problems coming with the digital-design and the attached digital-production. There for the course took part at our computerlab. In weekly workshops, all ideas have been implemented and tested directly in the 3-dimensional parametric model. And thanks to the interdisciplinary work with the Department of Structural Design also static factors had been considered, to optimize the form. Parallel to the digital form-finding process, the first prototypes have been produced by the students. By using the chairs 3D-CNC-Mills we were able to check the programmed connection detail in reality and apply the so learned lessons to the further development. After nearly 3 month of research, designing, planning and programming, we were able to produce the over 1000 different parts in only 4 days. By developing a special pre-stressed structure and connection detail it was also possible, to assemble the whole structure (13.5m x 4.5m x 4m) in only one day. The close connection between digital design (CAD) and digital manufacturing (CAM) is an important point of our doctrine. By the fact, that the students operate the machines themselves, but also implement projects on a scale of 1:1, they learn to independently evaluate these new tools and to use them in a meaningful way.

title	The Use of the Smart Geometry through Various Design Processes: Using the programming platform (parametric features) and generative components
source	Digitizing Architecture: Formalization and Content [4th International Conference Proceedings of the Arab Society for Computer Aided Architectural Design (ASCAAD 2009) / ISBN 978-99901-06-77-0], Manama (Kingdom of Bahrain), 11-12 May 2009, pp. 297-304
summary	The emergence of parametric generative design tools and prototyping manufacturing technology led to radical changes in architectural morphologies. This change increased the opportunity to develop innovative smart geometries. Integrating these algorithms in the parametric softwares led to variations in building design concepts increasing alternatives and decreasing the repetitive work previously needed in conventional CAD software. The chosen software in this research is Generative Components (GC). It is a software design tool for an associative and parametric design platform. It is tested for using Global Variables with associative functions during the concept creation and form GC comprises features. The results presented in this research may be considered an introduction to the smart geometry revolution. It deals with the generative design which applied in the design process from conceptual design phase, defining the problem, exploring design solutions, then how to develop the design phases. Office building is a building type which encourages new forms that needs computational processes to deal with repetitive functions and modular spaces and enclosed in a flexible creative structural skin. Generative design helps the office buildings to be arranged, analysed, and optimized using parameters in early stages in design process. By the end of the research, the use of the smart geometry in a high rise office building is defined and explained. The research is divided into three parts, first a summary of the basic theories of office buildings design and the sustainable requirements that affect it, and should be integrated. Secondly, the previous experiences in generating office buildings by Norman foster and Sergio Araya. At last, a case study is proposed to test and evaluate the use of the parametric generative methodology in designing an office building with specific emphasis on the function, environmental aspects and form generation using Generative Components (GC) Software.

summary	Nowadays, the architectural profession is seeking a better energy saving in the design of buildings. The fear of energy shortage in the very near future, together with the rapid rise in energy prices, put pressure on researchers on this field to develop buildings with more efficient heating systems and energy systems. This work is concerned mainly with the development of a software program analyzing comfort in buildings integrated in CAD architectural systems. The problem of presenting the computer with information concerning the building itself has been overcome through integration of thermal analysis with the building capabilities of CAD system. Mainly, such experience concerns the rules for calculating heat loss and heat gain of buildings in Algeria, The program has been developed in order to demonstrate the importance of the innovation of the computer aided-architectural-design field (CAAD) in the technology of buildings such as the three dimensional modeling offering environmental thermal analysis. CAAD is an integrated architectural design system which can be used to carry out many tasks such as working drawings, perspectives and thermal studies, etc., all from the same data. Results are obtained in tabular form or in graphical output on the visual display. The principle of this program is that all input data should be readily available to the designer at the early stages of the design before the user starts to run the integrated model. Particular attention is given to the analysis of thermal aspects including solar radiation gains. Average monthly energy requirement predictions have been estimated depending on the building design aspect. So, this integrated model (CAAD and simulation comfort) is supposed to help architects to decide on the best options for improving the design of buildings. Some of these options may be included at the early design stages analysis. Indications may also be given on how to improve the design. The model stored on CAAD system provides a valuable data base for all sort analytical programs to be integrated into the system. The amount of time and expertise required to use complex analytical methods in architectural practice can be successfully overcome by integration with CAAD system.

summary	A multi-agent system (MAS) is efficient as it can emulate a variety of organisms in natural science due to the interactions between agents, which make artificial systems responsive and adaptive. In “Bamboo Workshop” involved flexible structures, MAS was employed to create virtual organism in computational environment towards an innovative process in installation design. A generative tool with friendly user interface was developed for both observation and intervention besides debugging. At the same time investigations were carried on the complex behaviours of the system through graphic statistics. Integrated with the generative tool, a construction system made up of bamboo materials was set up to build a series of mobile and flexible installations. This experiment suggests that the virtual organism has the potential for being a part of the design intelligence, beyond a mere digital tool.

title	Creation of an Evolutive Conceptual Know-how Framework for Integrative Building Design

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.

title	Transdiciplinary Research Strategies: Investigating the Transition of Peer2Peer Relational Systems from Digital to Real-time Environments
source	SIGraDi 2009 - Proceedings of the 13th Congress of the Iberoamerican Society of Digital Graphics, Sao Paulo, Brazil, November 16-18, 2009
summary	The paper presents research and a case study investigating a series of events developed around Peer2Peer relational systems. The events emerged as a response to the identified needs forwarded by a post-graduate research group and evolved into information networks that serve an expanded, transdisciplinary community. The paper begins by reviewing a discussion model which integrated Peer2Peer relational principals within the event framework as a means of expanding transdisciplinary research and practice through peer networks, and concludes by considering the opportunities Peer2Peer relational systems offer to progress future university networks.

title	Adaptation as a Framework for Reconsidering High-Performance Residential Design: A Case Study

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.
