title	goBIM: BIM Review for the iPhone
doi	https://doi.org/10.52842/conf.acadia.2009.273
source	ACADIA 09: reForm( ) - Building a Better Tomorrow [Proceedings of the 29th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-0-9842705-0-7] Chicago (Illinois) 22-25 October, 2009), pp. 273-277
summary	This paper summarizes the development of goBIM, a model viewer, markup, and data-querying environment that utilizes Apple’s iPhone and Autodesk’s Revit software. Geometric and database information are written to a user defined server location via a custom Revit plugin. Model geometry and database information are loaded at run-time from the web server to the goBIM iPhone application, using a cellular network connection or WiFi. The user can then navigate the 3D environment, selecting objects to view their associated database information. The user has the ability to tag elements in the model with additional data, which can then be pushed back to the server and reloaded in the local version of the Revit model. BIM data can now be accessed anywhere there is a WiFi or cellular network connection available.

title	Testing the relevance of parameterization to architectural epistemology
source	Architectural Science Review, Volume 52.2: 135-141
summary	Advances in building information modeling (BIM) deeply impact the production of new architecture; its benefits are obvious and its acceptance widespread. But how does BIM impact the study of existing architecture? Can BIM be assumed to operate as a neutral framework, equally applicable to the study of architecture anywhere? Using as a point of departure a recent outline of the conceptual structure of parametric modeling prepared by Sacks, Eastman, and Lee (2004), this paper compares parametric models of two existing works of architecture: Mies van der Rohe’s Crown Hall and Peter Zumthor’s St. Benedict Chapel. The processes of parametrically modeling each building are specifically compared in two ways: first, parameters are established for each model; second, each model is "flexed" as a means of disclosing possible semantic relationships within each work of architecture. Because each building demands a different parameter-establishment strategy, and because the models permit different degrees of flexibility, the comparison illustrates the shortcomings of a "neutral framework" assumption to an architectural epistemology.

summary	Building Information Modeling (BIM) has the potential to fundamentally alter the way composition, scale and abstraction are addressed in today’s comprehensive design studio by displacing the primacy of abstract conventions of representation with a methodology based on systems thinking and virtual simulation. BIM viewed as provocateur of design education provides great potential for the critical analysis of how architectural design is taught. The design studio project reflects new ways of teaching and addressing BIM methods and processes, and critically evaluating their effects and possibilities on architectural production.

summary	The research presents the importance of the experimentations within education of architecture project. Since the studies for traditional and emergent ways with use them digital tools, it values the project inquiries in the simulations of the models in 3D. For many times, the digital model for being tangible cannot present a difficulty in the understanding of constructive details. As in the digital tools, more specifically BIM (Building Information Modeling) possess integrated standards complex. The necessity of the materialization becomes inevitable use of the Rapid Prototype (RP) that it is a technology that allows the materialization of the complex digital models facilitating to the tactile and percipient use for better understanding and taking of decision.

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	Rebuilding Architecture: An analysis and critical investigation practice
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. 121-134
summary	The Cooperative Design Environment Laboratory (CoDE Lab) is carrying out a research with students, trainees and seniors who have previously participated to CAAD-assisted design courses. These courses were developed with the aim of making participants independent from the pre-analytical phase project to the renderings of the final artifact. The programs that have been used so far are Autodesk Revit, Graphisoft Archicad and Nemetschek Allplan.The teaching workgroup has always believed that analyzing, deconstructing and reconstructing the architecture teaches much in terms of understanding. If the process is done correctly, it entirely re-traces the creative dynamics developed by the original designer. Subsequently, the educational practice is to choose a notable architectural work, designed and/or created by a Master of architecture, and to reproduce it in all details: aesthetical-formal, morphological, technological, structural, modular, etc. The final result is an archive of well-developed reconstructed models of great specific interest. The students on the other hand thoroughly learn how to control the tools and all BIM planning procedures.

summary	There is an increasing demand for building performance assessment among architects mostly due to a rising awareness for issues related to environmental sustainability. However, after thirty years of research, interoperability of performance analysis tools with CAAD environments is still far from being seamless. Yet, all commercial CAAD vendors have recently started offering an array of building analysis tools. It is fair to expect a new surge of efforts in integrating prediction and evaluation capabilities within CAAD systems over the next few years. Building on lessons learned, this paper argues the need for a unification infrastructure for building performance and outlines the requirements for building an analysis network.

summary	There is an increasing adoption of BIM technology in the AEC industry. Organizations are forced to restructure their practices. The role of the architect within the new multi-disciplinary design team will depend on the architects’ skills in communicating with other team members. Architecture schools need to prepare students for this change. Collaborative aspect of design should be incorporated into the curriculum. This paper reports on the collaboration initiative between the architecture and civil engineering departments at Bal_kesir University. The initiative is investigating the extent to which courses can be coordinated across departments. Students from three different courses have been asked to provide analysis and feedback for the same project concurrently. The results confirm that BIM technology can effectively support collaboration even among undergraduate students who are relatively inexperienced with interdisciplinary data exchange.

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.

title	O Uso de Modelagem Generativa para Representação de Modulações de Alvenarias em Ferramentas BIM
source	SIGraDi 2009 - Proceedings of the 13th Congress of the Iberoamerican Society of Digital Graphics, Sao Paulo, Brazil, November 16-18, 2009
summary	One approach to perform the design for production of masonry with BIM tools is to explicitly represent the wall elements. However, this strategy decreases the application performance because of model complexity. Generative Modeling is a modeling paradigm aimed at defining rules and applying them for generating models. The masonry block placement is associated with a set of rules, making the use of generative modeling a viable solution to implicitly represent the blocks. This paper presents some preliminary results of our research on investigating if Generative Modeling can help in the representation of masonry modulation and for the proposal of a shape grammar for representing its basic elements.

summary	The ultimate goal of the project in which the described research evolves is a computer-platform for assisting in the development of urban design proposals at the site planning scale including formulation, generation, and evaluation modules. The paper is concerned with the development of a common ontology that guarantees inter-operability among the three modules. After clarifying the theoretical framework, it describes the methodology used to develop the proposed Urban Design Ontology (UDO), as well as its lexicon, syntax, and semantics. It is argued that such ontology constitutes the bases for a City Information Model (CIM) that permits to elaborate consistent and comprehensive descriptions of urban spaces, thereby enabling the formulation of programs for urban interventions and the generation of corresponding design proposals.

summary	The evolution of the graphical representation of the architecture with the development of procedures for computer-aided designs is causing a shift in the way of thinking about architecture. Traditionally, the teaching of descriptive geometry that allows architects in training cognition full three-dimensional space. Changing this tradition, today we have the construction of the projective drawing by computer, CAD or BIM. We aim to question the way to teach courses in the projective geometry of architecture and urbanism in the face of profound changes in knowledge and representation of the form established by computer graphics technology with CAD and BIM.

title	Services in Digital Design: new visions for AEC-field collaboration
source	International Journal of Architectural Computing vol. 7 - no. 3, 459-478
summary	The objective of this paper is to describe contemporary digital building design from a service provider aspect. The constrained framework of this work is digital architectural design practice. When design is seen in the context of the AEC field, a process oriented approach is commonly used in describing collaboration and evolutionary progress of the design work as a project. Design projects are scheduled chains of activities which result in design delivery or actual physical buildings as the end products of the project. Recently developments in building information modelling (BIM) have presented fundamentally new ways for collecting, exploring, and sharing design information. This study develops the novel digital approach: BIM as design services. The key finding of the study is that parts of the design domain can be described as services in the changing digital environment. The scientific contribution of this paper is in describing contemporary digital design practice with an alternative service approach. A framework for such services is also presented. This work will expand the authors' contribution to research on preliminary architectural design using building information models.

summary	Building Information Modeling may have obvious implications in the process of architectural design and construction at the present stage of technological development. However, BIM has rarely been really assessed and its benefits are often described in generic terms. In this paper we describe an experiment in which such benefits are identified from a comparison between two design processes of the same airport building, one run in a conventional way and the other in a BIM-based approach. The practical advantages of BIM to airport design were remarkable.

source	SIGraDi 2009 - Proceedings of the 13th Congress of the Iberoamerican Society of Digital Graphics, Sao Paulo, Brazil, November 16-18, 2009
summary	Interoperability is the ability of two or more systems to exchange information. It is one of the pillars of BIM because the information contained in a BIM model needs to be exchanged to be useful. IFC is cited as the best option for achieving interoperability in Construction but, although several applications have been certified to be IFC-compliant, flawed exchanges are too common yet. Behind IFC, some other less known standards play an important role to make BIM interoperability a reality. Among them are IDM, MVD and IFD. This paper will briefly show how these standards take part in data exchange and discuss the reasons why AEC interoperability is still such an elusive goal.

summary	This paper describes the successful development of a design supporting method called ‘Ubicomp-Kaizen’ for the design of computerintegrated ‘smart’ buildings. The tool uses known methods of qualitymanagement of the car-manufacturing industry and integrates them into the architectural design process. By this, the CAAD-topics ‘design methodology’, ‘ubicomp/smart buildings’, ‘interactive architecture’ and ‘Building Information Model (BIM)’ are involved. In result it proves the successful integration and application of tools known from the product development industry such as ‘Quality-Function-Deployment (QFD)’ and ‘Failure Mode and Effects Analyze (FMEA)’ within the iterative building design. The outlook formulates a side-result which is the setup of a digital decision supporting tool and the extension of the IFC-definitions in order to integrate aspects of user-interaction and ubicomp."

title	Architect Friendly: A Comparison of Ten Different Building Performance Simulation Tools
source	IBPSA
summary	Performance Simulation tools BPS is available internationally. The users of those tools are mainly researchers, physicists and experts who value empirical validation, analytical verification and calibration of uncertainty as defined by e.g. BESTEST. However, literature and comparative surveys indicate that most architects who use BPS tools in design practice are much more concerned with the (1) Usability and Information Management (UIM) of interface and (2) the Integration of Intelligent design Knowledge-Base (IIKB). Those two issues are the main factors for identifying a building simulation program as “Architect Friendly”. Now, with the advancement of BPS tools and the recent announcements of direct links between BIM or non-BIM modeling tools and BPS tools it is important to compare the existing programs. Based on an online survey, this paper presents the results of comparing ten major BPS tools. The following programs are compared: ECOTECT, HEED, Energy 10, Design Builder, eQUEST, DOE-2, Green Building Studio, IES VE, Energy Plus and Energy Plus-SketchUp Plugin (OpenStudio). With 249 valid responses, the survey ranked the tools in three classes and revealed that architects seek the IIKB above the UIM of the interface. Finally, the paper summarizes the key findings and underlines the major requirements for future improvement and development of BPS tools, mainly from an architectural perspective.

title	Preliminary Concept Design (PCD) Tools for Laboratory Buildings, Automated Design Optimization and Assessment Embedded in Building Information Modeling (BIM) 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. 451-476.
summary	The design of laboratory buildings entails the implementation of a variety of design constraints such as building codes; design guidelines and technical requirements. The application of these requires from designers the derivation of data not explicitly available at early stages of design, at the same time there is no precise methodology to control the consistency, and accuracy of their application. Many of these constraints deal with providing secure environmental conditions for the activities inside laboratories and their repercussions both for the building occupants and population in general, these constraints mandate a strict control over the building‚Äôs Mechanical Equipment (MEP), in particular the Heating Ventilating and Air Conditioning (HVAC) system. Due to the importance of these laboratory designers are expected to assess their designs not only according spatial relationships, but also design variables such as HVAC efficiency, air pressure hierarchies, operational costs, and the possible implications of their design decisions in the biological safety of the facility. At this point in time, there are no practical methods for making these assessments, without having constant interaction with HVAC specialists. The assessment of laboratory design variables, particularly those technical in nature, such as dimensioning of ducts or energy consumption are usually performed at late stages of design. They are performed by domain experts using data manually extracted from design information, with the addition of domain specific knowledge, the evaluation is done mostly through manual calculations or building simulations. In traditional practices most expert evaluations are performed once the architectural design have been completed, the turn around of the evaluation might take hours or days depending on the methods used by the engineer, therefore reducing the possibility for design alternatives evaluation. The results of these evaluations will give clues about sizing of the HVAC equipment, and might generate the need for design reformulations, causing higher development costs and time delays. Several efforts in the development of computational tools for automated design evaluation such as wheel chair accessibility (Han, Law, Latombe, Kunz, 2002) security and circulation (Eastman, 2009), and construction codes (ww.Corenet.gov.sg) have demonstrated the capabilities of rule or parameter based building assessment; several computer applications capable of supporting HVAC engineers in system designing for late concept or design development exist, but little has been done to assess the capabilities of computer applications to support laboratory design during architectural Preliminary Concept Design(PCD) (Trcka, Hensen, 2010). Developments in CAD technologies such as Building Information Modeling (BIM) have opened doors to formal explorations in generative design using rule based or parametric modeling [7]. BIM represents buildings as a collection of objects with their own geometry, attributes, and relations. BIM also allows for the definition of objects parametrically including their relation to other model objects. BIM has enabled the development of automated rule based building evaluation (Eastman, 2009). Most of contemporary BIM applications contemplate in their default user interfaces access to design constraints and object attribute manipulations. Some even allow for the application of rules over these. Such capabilities make BIM viable platforms for automation of design data derivation and for the implementation of generative based design assessment. In this paper we analyze the possibilities provided by contemporary BIM for implementing generative based design assessment in laboratory buildings. In this schema, domain specific knowledge is embedded in to the BIM system as to make explicit design metrics that can help designers and engineers to assess the performance of design alternatives. The implementation of generative design assessments during PCD can help designers and engineers to identify design issues early in the process, reducing the number of revisions and reconfigurations in later stages of design. And generally improving design performance.

summary	Daylighting is an important part of designing sustainably. Daylighting is the use of natural light for primary interior illumination. This reduces our need for artificial light within the space, thus reducing internal heat gain and energy use. Direct sunlight, once it enters the building, is not only light but heat, and that additional heat will need to be taken into account in your energy analysis." While Autodesk Revit Architecture 2010 (ARA) itself cannot perform the actual analysis, there are some ways to do that. This papper focuses on the study of parametric modeling using a BIM tool for daylighting analysis. This paper presents the first part of the building method of LUME, a plug-in maked whit C# programming language in Microsoft Visual Studio 2010 and ARA Software Developer Kit (SDK) package. The script accepts as its input a standard three dimensional model of building opening and his position on space.
