title	Hypermedia urban models in virtual environments: Case studies of central areas of Argentine cities
source	International Journal of Architectural Computing vol. 6 - no. 3, pp. 221-241
summary	The virtual models of urban fragments recreate environments of simulation and analysis with a great degree of realism. This paper addresses a review of case studies in which Argentine researchers from three different university centres have worked jointly. We examine spatial databases from a representational and communicational perspective as virtual 3D, walkthrough, and interconnected urban models. Our aim is to explore, recognise and analyse advances in this direction, and to apply them to the development of virtual models of central areas in the Argentine cities of Buenos Aires, Rosario, Santa Fe and Mar del Plata. We present the methodology used to analyse the design, production and management processes of the virtual model as well as the results of our research. We acknowledge that these models are consistent non-traditional instruments of analysis which complement the knowledge of the city and facilitate spatial comprehension. Finally, we review predominant tendencies.

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	In this research project we explore the defined design and application of digitally fabricated wall panels for room-acoustical architectural interventions. In Particular, we investigate the room-acoustical criteria applying to everyday used spaces. We present a digital design and fabrication process developed to create non-standardised panels and two case studies which apply this process on the acoustical improvement of a specific room situation. Our aim is to find correlations between digitally fabricated surface structures and sound- aesthetical characteristics, in order to utilise these for the architectural design.

title	Road hierarchy and speed limits in Brasília/Brazil
source	H.J.P. Timmermans, B. de Vries (eds.) 2008, Design & Decision Support Systems in Architecture and Urban Planning, ISBN 978-90-6814-173-3, University of Technology Eindhoven, published on CD
summary	This paper aims at exploring the theory of the Social Logic of Space or Space Syntax as a strategy to define parameters of road hierarchy and, if this use is found possible, to establish maximum speeds allowed in the transportation system of Brasília, the capital city of Brazil. Space Syntax – a theory developed by Hillier and Hanson (1984) – incorporates the space topological relationships, considering the city shape and its influence in the distribution of movements within the space. The theory’s axiality method – used in this study – analyses the accessibility to the street network relationships, by means of the system’s integration, one of its explicative variables in terms of copresence, or potential co-existence between the through-passing movements of people and vehicles (Hillier, 1996). One of the most used concepts of Space Syntax in the integration, which represents the potential flow generation in the road axes and is the focus of this paper. It is believed there is a strong correlation between urban space-form configuration and the way flows and movements are distributed in the city, considering nodes articulations and the topological location of segments and streets in the grid (Holanda, 2002; Medeiros, 2006). For urban transportation studies, traffic-related problems are often investigated and simulated by assignment models – well-established in traffic studies. Space Syntax, on the other hand, is a tool with few applications in transport (Barros, 2006; Barros et al, 2007), an area where configurational models are considered to present inconsistencies when used in transportation (cf. Cybis et al, 1996). Although this is true in some cases, it should not be generalized. Therefore, in order to simulate and evaluate Space Syntax for the traffic approach, the city of Brasília was used as a case study. The reason for the choice was the fact the capital of Brazil is a masterpiece of modern urban design and presents a unique urban layout based on an axial grid system considering several express and arterial long roads, each one with 3 to 6 lanes,

title	Adopting Building Information Modeling (BIM) as Collaboration Platform in the Design Industry
doi	https://doi.org/10.52842/conf.caadria.2008.053
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. 53-60
summary	This paper discusses the preliminary findings of an ongoing research project aimed at developing a technological, operational and strategic analysis of adopting BIM in AEC/FM (Architecture-Engineering-Construction/Facility Management) industry as a collaboration tool. Outcomes of the project will provide specifications and guidelines as well as establish industry standards for implementing BIM in practice. This research primarily focuses on BIM model servers as a collaboration platform, and hence the guidelines are aimed at enhancing collaboration capabilities. This paper reports on the findings from: (1) a critical review of latest BIM literature and commercial applications, and (2) workshops with focus groups on changing work-practice, role of technology, current perception and expectations of BIM. Layout for case studies being undertaken is presented. These findings provide a base to develop comprehensive software specifications and national guidelines for BIM with particular emphasis on BIM model servers as collaboration platforms.

title	The teleplastic abuse of ornamentation
source	First International Conference on Critical Digital: What Matters(s)? - 18-19 April 2008, Harvard University Graduate School of Design, Cambridge (USA), pp. 383-392
summary	Is it possible that psychoanalysis, a discipline that allegedly deals with abstract or invisible entities, and entomology, a discipline that predominantly taxonomizes insects by type, can offer us an insight into the nature of digital design processes and emergent material phenomena? One of Roger Caillois’ most controversial psychoanalytic theories, “teleplasty,” shows that psychoanalysis and entomology can indeed suggest an alternative perspective of how bodily or other material substances are initially fabricated by insects and how they can further transform. In several of his case studies, Caillois claims alliances between material and psychical structures in his psycho-material teleplastic theorem and eventually questions spatial distinctions: distinctions between geometry and material, purpose and function, cause and effect, between the imaginary and the real. Can digital media help us redefine the static relationship between a window and a wall as an interaction of chemical substances rather than a process of assembling joints and components? Can we perceive material, not as an application to predetermined geometries, but as an inherent condition, a subatomic organization of matter that precedes geometry? The aim of this paper is to problematize such distinctions as a discussion emerging through the prolific use of digital design processes.

title	Implementations and Applications of DesignMap: Case Studies to Manage an Online Database of Visual Designs
source	International Journal of Architectural Computing vol. 6 - no. 3, pp. 243-258
summary	This research introduces state-of-the-art techniques in the areas of online libraries, communities, and forums. The research endeavours to describe a computer system called DesignMap that could be categorized as a visual design forum. This system encourages networking and can also be applied as a visual design library. The DesignMap system, which manages and displays a massive number of visual designs in two and three dimensions, was presented and discussed in a previous research. This project, however, is concerned with the application of DesignMap as a tool to search, visualize, modify, and then add designs in a map; these designs are classified based on their formal properties of object relationships. DesignMap users have access to any part or category in the map. The resulting design series created by users of this system present a new and unique form of design collaboration. The research also investigates several applications of the DesignMap system.

title	From Concept to Reality: Digital Systems in Architectural Design and Fabrication
source	International Journal of Architectural Computing vol. 6 - no. 4, 397-413
summary	One of the challenges for today's architectural designers is the establishment of continuous digital processes between design and fabrication. To achieve this, designers need to acquire knowledge about the production and the methods and tools involved. Two case studies organized at the Norwegian University of Science and Technology (NTNU) on digital timber fabrication investigate the new field of collaboration between architectural designers and fabricators. The studies demonstrate the design potential of acquiring insights into the fabricators' software and digital production machinery and reflect contemporary fabrication technology in formal expression. We identified two different approaches to formal exploration that we defined as "sophistication of the detail" and "variation of the element".

summary	“Why do we have to change? We’ve been building buildings for years without CATIA?” Roger Norfleet, a practicing architect in his thirties poses this question to Tim Quix, a generation older and an expert in CATIA, a computer-aided design tool developed by Dassault Systemes in the early 1980’s for use by aerospace engineers. It is 2005 and CATIA has just come into use at Paul Morris Associates, the thirty-person architecture firm where Norfleet works; he is struggling with what it will mean for him, for his firm, for his profession. Computer-aided design is about creativity, but also about jurisdiction, about who controls the design process. In Architecture: The Story of Practice, Architectural theorist Dana Cuff writes that each generation of architects is educated to understand what constitutes a creative act and who in the system of their profession is empowered to use it and at what time. Creativity is socially constructed and Norfleet is coming of age as an architect in a time of technological but also social transition. He must come to terms with the increasingly complex computeraided design tools that have changed both creativity and the rules by which it can operate. In today’s practices, architects use computer-aided design software to produce threedimensional geometric models. Sometimes they use off-the-shelf commercial software like CATIA, sometimes they customize this software through plug-ins and macros, sometimes they work with software that they have themselves programmed. And yet, conforming to Larson’s ideas that they claim the higher ground by identifying with art and not with science, contemporary architects do not often use the term “simulation.” Rather, they have held onto traditional terms such as “modeling” to describe the buzz of new activity with digital technology. But whether or not they use the term, simulation is creating new architectural identities and transforming relationships among a range of design collaborators: masters and apprentices, students and teachers, technical experts and virtuoso programmers. These days, constructing an identity as an architect requires that one define oneself in relation to simulation. Case studies, primarily from two architectural firms, illustrate the transformation of traditional relationships, in particular that of master and apprentice, and the emergence of new roles, including a new professional identity, “keeper of the geometry,” defined by the fusion of person and machine. Like any profession, architecture may be seen as a system in flux. However, with their new roles and relationships, architects are learning that the fight for professional jurisdiction is increasingly for jurisdiction over simulation. Computer-aided design is changing professional patterns of production in architecture, the very way in which professionals compete with each other by making new claims to knowledge. Even today, employees at Paul Morris squabble about the role that simulation software should play in the office. Among other things, they fight about the role it should play in promotion and firm hierarchy. They bicker about the selection of new simulation software, knowing that choosing software implies greater power for those who are expert in it. Architects and their collaborators are in a continual struggle to define the creative roles that can bring them professional acceptance and greater control over design. New technologies for computer-aided design do not change this reality, they become players in it.

title	Beyond Surface: Aspects of UVN world in Algorithmic Design
source	First International Conference on Critical Digital: What Matters(s)? - 18-19 April 2008, Harvard University Graduate School of Design, Cambridge (USA), pp. 195-204
summary	The need for architects to develop their own computational tools is becoming increasingly evident. In this paper, we introduced our design tool named ‘UVN generator’ which is based on the algorithmic process combining scripting potentiality and flexibility of traditional 3D surface modeling. Our attempt on combining the two served us well to explore the new ground for design. New conditions were explored and observed in the three case studies which are named ‘on a surface’, ‘between surfaces’ and ‘on a new ordered surface’, referring to place where the scripts were run. In design projects presented in our case studies, we focus on the system behind the generation of complex, expressive, biomimetic, yet humanistic shape. This challenge to find a new ground for computational design enables us to pose our critical question ‘What could be algorithmic design potential may lay beyond basic surfaces?’

title	Evaluating VBE AND BIM-frameworkS A Cost Estimation Case Study and Reflections to Environmental Issues
doi	https://doi.org/10.52842/conf.caadria.2008.081
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. 81-88
summary	This paper describes and evaluates two recently emerged concepts, Virtual Building Environment VBE and Building Information Modelling BIM, fitting them into the context of contemporary design and construction. Both are elementary concepts in modern digitally “reinforced” design and construction. A case study of cost estimation is presented to illustrate how discipline related issues are currently managed within VBE and BIM. An environmental aspect is presented as a corresponding domain to evaluate the other use cases of building related information. Other similar domains to be evaluated perhaps in further case studies could be the functional user aspect, the project management aspect and the regulating aspect by the society and authorities. A hypothetical assumption is, that methods and technologies which are currently used within VBE and BIM, mainly by designers, can well support various data extractions from BIM-models, but they may not serve all construction process participants in the most beneficial way. Also wider scale building portfolios are requested as conceptual extensions to VBE and BIM. This study is based on ongoing PhD studies on building information modelling and environmental life cycle assessment.

title	Copenhagen Elephant House: A Case Study of Digital Design Processes
doi	https://doi.org/10.52842/conf.acadia.2008.134

summary	This paper outlines the digital design processes involved in the design and construction of the new Elephant House at Copenhagen Zoo. Early design concepts for the canopy were tested using physical sketch models. The geometric complexity of these early physical models led to the involvement of the Specialist Modelling Group and the use of the computer to digitally sketch 3D CAD models. After many studies, the complex form of the canopies was rationalised using torus geometry. A computer program was written to generate the canopy glazing and structure. This parametric system was developed to be a design tool, and was developed by an architectural designer working with the team. Through its use the team were able to explore more design options, and alter the design farther along in the design process; however, this generative tool was created largely as a CAD efficiency tool. Another series of computer programs were written to generate and populate a shading system based on environmental analysis. Unlike the computer program that generated the structure and glazing, this program was not developed to make the generation of complex geometric structures more efficient, but developed to explore computational approaches that would have been impossible without the computer. Most of the canopy’s design was communicated to fabricator through a geometry method statement, a method that has been proven to be effective in the past. The project completed in June 2008.

summary	ZipShape is a universal method to fabricate single curved panels from any plain material without molds. The system uses two individually slotted panels that interlock when bent to the predefined curvature. As non-radial curves require individual teeth geometry, the method makes use of automated detailing with corresponding algorithms. ZipShape is a fusion of information processing and material processing based on comparatively simple software technology and standard workshop machinery. With help of case studies, this paper evaluates the method’s claim to be a variable and feasible solution for the realization of non-planar shape.

summary	In practice, the domains of architecture and computation have traditionally been perceived as distinct. Computation and its associated technologies, such as computers and software applications, have primarily only been applied to the domain of architecture. The aim of this paper is to reconsider the relationship between these domains. In moving away from separate entities towards a synthesis of architecture and computation, this paper explores the potential and the challenges of this rich creative space that opens up for architectural design through a series of case studies.

title	Architectural Brand valuations through a tag-based learning machine.
source	SIGraDi 2008 - [Proceedings of the 12th Iberoamerican Congress of Digital Graphics] La Habana - Cuba 1-5 December 2008
summary	Brand is a set of associations related to an object from a particular source (Libai 2008). Such an object can be a product, person or service. Architecture is both service and product. However architectural Branding has never been clearly defined. This probably happens due to the lack of tools to measure the architectural Brand. This paper explores a direction to evaluate the architectural Brand by using computational methods in order to offer a better understanding regarding the awareness, reputation and prominence of the architectural firm. The methodology is based on case studies in which the brands of different types of architectural firms are analyzed, measured and compared to each other through a two-part process: a. the development of one tool to statistically measure the architectural Brand and b. the interpretation of the results of the measurements. a. Learning machine In order to make these brand measurements within a specific group of people or images, this paper develops an interactive tool that uses an image database. The tool constitutes a learning machine; it makes a hypothetic hierarchical categorization of the image database into + and – using an initial sample and it proposes to the user the first image of the list; finally, the user validates the image by confirming or not the machine’s guess. In this image database, each image is described as an array of attributes (tags). Tags can be generated either by the architectural firm itself or can emerge by users. b. Evaluation of results This interactive, user-friendly tool is drawing a user’s preference by proposing similar images from the database based on a learning process from the user input (initial sample and feedback); alternatively, it can be used as a questionnaire for quantitative research. Moreover, this tool categorizes photos of similar content. This research focuses on the following issues as parameters of the effectiveness of the process: o Simplicity of the database organization through computation. o Top-down Vs. Bottom-up tagging of works/ images mechanism. o Future use of the image database. o Transformation of the image database while becoming larger. o “Market” segmentation or not. o Combination of the tool with other Brand measurement tools. o Combination of the tool with other image databases. The outcome of this approach can provide an analysis and metric of the brand strength of different architectural firms. Furthermore, it can help architectural firms to understand better how they are perceived by others in order to improve their brand image and associations.

title	Digital Database of Building Structural Systems: an Educational Tool to Support Multi-disciplinarity and Enrich Design Vocabulary in Preliminary Conceptual Structural Design
doi	https://doi.org/10.52842/conf.ecaade.2008.397
source	Architecture in Computro [26th eCAADe Conference Proceedings / ISBN 978-0-9541183-7-2] Antwerpen (Belgium) 17-20 September 2008, pp. 397-404
summary	In building design practice, especially in the preliminary stages, multi-disciplinarity is often ignored, due to the intrinsic characteristics of the design process, the features of design education, or lack of appropriate tools, resulting in a limited design vocabulary. This paper investigates the development of a digital multi-media database of building structures, operating as a supporting tool in preliminary structural design in order to enrich and justify design decisions. The proposed database responds to the need of bridging the gap between systematic, yet abstract, theoretical analytical approach of structural systems and descriptive, visual, yet fragmented, representations of architectural forms, through a highly visual, yet thoroughly systematic, approach based on case-studies.

summary	This paper describes our research on environment-behavior simulation and focuses on the modeling of built environments using Computer-Aided Design (CAD) and Building Information Modeling (BIM). Our environment-behavior simulation addresses the problem of predicting and evaluating the impacts of built environments on their human inhabitants. We present simulation systems comprising an agent-based virtual user model and building models created with CAD and BIM tools. We compare the use of CAD vs. BIM with two case studies for environment-behavior simulation, and describe the essential parts of modeling buildings for the simulation, including geometry modeling—how the building components are shaped, semantic modeling—what the building components are, and pattern modeling—how the building components are used by users. We conclude that a new extensible and pattern-embedded BIM system will be necessary to facilitate environment-behavior simulation.

summary	Although it was proven by many field studies of office environments that complete thermal user satisfaction can only be achieved by setting the indoor climate to individual user preferences, open-plan offices do not support this requirement. In addition, irregular occupancy of such offices leads to suboptimal energy usage. This paper will show how the design of such offices can be supported by tools that integrate individual thermal user preferences and schedules into performance simulations to test and evaluate different partitioning structures, HVAC equipment, and control strategies in regard to satisfaction and energy consumption. A case study is used as demonstrator.

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.
