title	A Strategic Planning and Policy Decision Support Tool for Urban Regions
source	Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary	In this paper we present a Decision Support System developed to assist urban designers, planners and policy makers to explore and evaluate possible urban layouts and their growth patterns. Thecore of the system consists of a modelling shell allowing the user to specify cellular automata based models of urban and regional systems. These models capture the effect of local spatial processes in which the use, or desired use of each parcel or cell of land is determined partly by institutional and environmental factors, and partly by the activities present in its neighbourhood. Since each cell affects every other cell within its neighbourhood, a complex dynamic emerges. Unlike conventional cellular automata, the models are defined with a large neighbourhood --over a hundred cells-- a relatively large number of states --more than a dozen in some applications-- representing socio-economic and natural land-uses. The approach permits the straightforward integration of detailed physical, environmental, and institutional constraints, as well as including the effects of the transportation and communication infrastructure. These models thus permit a very detailed representation of evolving spatial systems. The current version of the system represents urban areas as consisting of up to 10.000 interacting zones, each roughly the size of an individual city block. These models are easy to build and apply, yet empirical tests show that they produce realistic simulations of urban land use dynamics. Consequently, they are well suited to form the heart of the DSS, which provides the user with a number of tools for exploration,analysis and evaluation of alternative futures of the system as they result from policy interventions that are imposed by means of what-if experiments and scenario analysis. For example, the DSS isable to identify areas in which pressure for change in land use restrictions may become critical under particular development strategies. In the DSS, the modelling shell is coupled to a simple,custom-built GIS. In the stand-alone application of the DSS, this stores the detailed geographical qualities of the area being modelled, and allows basic overlay manipulations. It also displays theresults of the model while the simulation proceeds. Alternatively, the GIS can serve as aninterface to more elaborate, commercial GIS systems.

title	THe "Allots" Model: A PC-Based Approach to Demand Distribution for Siting and Planning
source	Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary	This paper reports on the development and application of ALLOT: a user-friendly, flexible computer model which has been designed to help governmental jurisdictions and private landowners throughout the world to achieve more economically efficient and environmentally sound land use and development patterns in a short period of time. ALLOT has the potential to drastically change the way that land use planning is conducted, since it has the capability to allow theincorporation of a wide variety of previously ignored environmental characteristics and up-to-date land use patterns. ALLOT, which is written in the SAS programming language, contains twomajor parts. The first part employs a GIS database to conduct land suitability analyses for the area. It then produces maps showing the most suitable areas for various land use types. The second part appears to be unique in the field of computerized land use planning models. It combines the results of the suitability analysis with forecasted demand for various land use types to produce "optimum" future land use patterns. The model is capable of quickly analyzing a wide variety of forecasts, allowing easy comparison of different growth scenarios; and it can also be modified to reflect community goals and objectives, such as protection of wildlife habitat orattraction of industry. The flexibility, combined with the fact that it runs on any IBM-compatible PC (286 or higher), make it a powerful land use planning tool. The model has been successfully applied in two "real world" situations. First, three alternative future land use patterns were developed for a rural lakeside area. The area had rural characteristics and was lacking infrastructure, but a large influx of people was expected as the lake was filled. The success of this effort led to decision to test it´s use as a method for facility siting (using landfill siting as an example).

title	Improved Understanding of Urban Sprawl Using Neural Networks
source	Van Leeuwen, J.P. and H.J.P. Timmermans (eds.) Recent Advances in Design & Decision Support Systems in Architecture and Urban Planning, Dordrecht: Kluwer Academic Publishers, ISBN: 14020-2408-8, p. 33-49
summary	It is widely accepted that the spatial pattern of settlements is a crucial factor affecting quality of life and environmental sustainability, but few recent studies have attempted to examine the phenomenon of sprawl by modelling the process rather than adopting a descriptive approach. The issue was partly addressed by models of land use and transportation which were mainly developed in the UK and US in the 1970s and 1980s, but the major advances were made in the area of modelling transportation, while very little was achieved in the area of spatial and temporal land use. Models of land use and transportation are well-established tools, based on explicit, exogenouslyformulated rules within a theoretical framework. The new approaches of artificial intelligence, and in particular, systems involving parallel processing, (Neural Networks, Cellular Automata and Multi-Agent Systems) defined by the expression “Neurocomputing”, allow problems to be approached in the reverse, bottom-up, direction by discovering rules, relationships and scenarios from a database. In this article we examine the hypothesis that territorial micro-transformations occur according to a local logic, i.e. according to use, accessibility, the presence of services and conditions of centrality, periphericity or isolation of each territorial “cell” relative to its surroundings. The prediction capabilities of different architectures of supervised Neural networks are implemented to the south Metropolitan area of Milan at two different temporal thresholds and discussed. Starting from data on land use in 1980 and 1994 and by subdividing the area into square cells on an orthogonal grid, the model produces a spatial and functional map of urbanisation in 2008. An implementation of the SOM (Self Organizing Map) processing to the Data Base allows the typologies of transformation to be identified, i.e. the classes of area which are transformed in the same way and which give rise to territorial morphologies; this is an interesting by-product of the approach.

title	The Design of Decision Support Systems in Urban and Regional Planning
source	Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary	Planning methodology over the years, has shifted from situations whereby planners think, plan and design for the people to one whereby both people and planners have become important components of the planning process. Consequently, the important urban planning methodology of the last two decades that utilized mathematical models in the planning process is fast becoming obsolete. The paper argues that model building should move to the creation of urban decision support systems for the planning process through the development of expert systems shells that interfaces existing planning models with the knowledge content of planning and planners. The expert system shells as the set of decision rules for determining how existing supply and demand relationships are applied for modelling land use and transportation would be responsible forguiding the development of appropriate geographical information systems, supporting land use and other models in a coordinated manner, for communicating with these other systems componentsand for guiding interactions between them and the user. Furthermore, decision support systems should be designed to bring the whole of the knowledge base to bear on a problem through a flexible and adaptive solution system that makes explicit use of both the analysts models and the decision makers expert knowledge. It is argued that this understanding leads to the development of three crucial issues for the design of decision support systems in urban and regional planning;namely the development of user friendly integrated urban land-use transportation models, the development of expert geographical information systems and the development of expert systemshells for many of the routine tasks planners deal with.

title	A digital Procedure of Building Construction: A practical project
source	AVOCAAD - ADDED VALUE OF COMPUTER AIDED ARCHITECTURAL DESIGN, Nys Koenraad, Provoost Tom, Verbeke Johan, Verleye Johan (Eds.), (2001) Hogeschool voor Wetenschap en Kunst - Departement Architectuur Sint-Lucas, Campus Brussel, ISBN 80-76101-05-1
summary	In earlier times in which computers have not yet been developed well, there has been some researches regarding representation using conventional media (Gombrich, 1960; Arnheim, 1970). For ancient architects, the design process was described abstractly by text (Hewitt, 1985; Cable, 1983); the process evolved from unselfconscious to conscious ways (Alexander, 1964). Till the appearance of 2D drawings, these drawings could only express abstract visual thinking and visually conceptualized vocabulary (Goldschmidt, 1999). Then with the massive use of physical models in the Renaissance, the form and space of architecture was given better precision (Millon, 1994). Researches continued their attempts to identify the nature of different design tools (Eastman and Fereshe, 1994). Simon (1981) figured out that human increasingly relies on other specialists, computational agents, and materials referred to augment their cognitive abilities. This discourse was verified by recent research on conception of design and the expression using digital technologies (McCullough, 1996; Perez-Gomez and Pelletier, 1997). While other design tools did not change as much as representation (Panofsky, 1991; Koch, 1997), the involvement of computers in conventional architecture design arouses a new design thinking of digital architecture (Liu, 1996; Krawczyk, 1997; Murray, 1997; Wertheim, 1999). The notion of the link between ideas and media is emphasized throughout various fields, such as architectural education (Radford, 2000), Internet, and restoration of historical architecture (Potier et al., 2000). Information technology is also an important tool for civil engineering projects (Choi and Ibbs, 1989). Compared with conventional design media, computers avoid some errors in the process (Zaera, 1997). However, most of the application of computers to construction is restricted to simulations in building process (Halpin, 1990). It is worth studying how to employ computer technology meaningfully to bring significant changes to concept stage during the process of building construction (Madazo, 2000; Dave, 2000) and communication (Haymaker, 2000).In architectural design, concept design was achieved through drawings and models (Mitchell, 1997), while the working drawings and even shop drawings were brewed and communicated through drawings only. However, the most effective method of shaping building elements is to build models by computer (Madrazo, 1999). With the trend of 3D visualization (Johnson and Clayton, 1998) and the difference of designing between the physical environment and virtual environment (Maher et al. 2000), we intend to study the possibilities of using digital models, in addition to drawings, as a critical media in the conceptual stage of building construction process in the near future (just as the critical role that physical models played in early design process in the Renaissance). This research is combined with two practical building projects, following the progress of construction by using digital models and animations to simulate the structural layouts of the projects. We also tried to solve the complicated and even conflicting problems in the detail and piping design process through an easily accessible and precise interface. An attempt was made to delineate the hierarchy of the elements in a single structural and constructional system, and the corresponding relations among the systems. Since building construction is often complicated and even conflicting, precision needed to complete the projects can not be based merely on 2D drawings with some imagination. The purpose of this paper is to describe all the related elements according to precision and correctness, to discuss every possibility of different thinking in design of electric-mechanical engineering, to receive feedback from the construction projects in the real world, and to compare the digital models with conventional drawings.Through the application of this research, the subtle relations between the conventional drawings and digital models can be used in the area of building construction. Moreover, a theoretical model and standard process is proposed by using conventional drawings, digital models and physical buildings. By introducing the intervention of digital media in design process of working drawings and shop drawings, there is an opportune chance to use the digital media as a prominent design tool. This study extends the use of digital model and animation from design process to construction process. However, the entire construction process involves various details and exceptions, which are not discussed in this paper. These limitations should be explored in future studies.

title	First Drawings, Then Semantics
doi	https://doi.org/10.52842/conf.acadia.1994.013

summary	The Semantic Modeling Extension (SME) prototype implements a unique approach to integrated architectural CAD that places the drawing act first in the design process. After drawing a design idea using a computer graphic system, the designer interprets the design, providing semantic content to the graphic entities. An interpretation expresses the meaning of the design with respect to a particular issue, such as structural sufficiency, energy consumption, or requirements for egress, and provides reasoning to evaluate the design addressing that issue. A design may have many interpretations to express the multiple issues that are relevant in a design project. The designer may add or delete interpretations of the design as issues change during the course of the project. Underlying the SME prototype are the concepts of form, function and behavior. In the prototype, evaluation of a design is done by deriving behavior from the graphically represented forms and relating the behavior to stated functions or requirements. The concepts of interpretations and form, function and behavior together establish a virtual product model for design. In contrast to component based approaches to product modeling that tightly bind form representations to their behavior and function, a virtual product model allows the designer to manipulate the relations among these three descriptors of a design, and thus manipulate the semantics of the design entities. By distinguishing between the act of proposing a design by drawing the conceived form and the act of assigning meaning to the form, the virtual product model approach supports both graphic thinking for design synthesis and symbolic reasoning for design evaluation. This paper presents a scenario of the use of the SME prototype in building design; provides an analysis of the design process and computational support described in the scenario; contrasts a virtual product model approach with a component-oriented product model approach; describes the software implementation of SME; and presents implications and conclusions regarding design process and technical integration.

title	Computer Aided Urban Design
source	Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary	The product of the Urban Design process in the public sector in the UK is usually a briefing document of some kind which communicates design ideas in outline both to the lay public and to private developers. The problem with briefing effectively is that outline expression of ideas does not provide a strong basis for negotiation with developers; the temptation therefore is to work up one proposal in detail and to present it as the only option. This type of prescriptive briefing may be successful in situations where the public body has control over the land, the economy is buoyant and the site has a simple context. Its problems are that it is labour intensive, so some areas are covered in detail, others not at all; it is seen as restrictive by developers, so may create a climate of conflict rather than certainty; it is not responsive to change; it covers specific sites thoroughly but does not deal well with large, complex areas; on large sites it tends towards a homogeneous environment whereas the nature of towns and cities is pluralistic and heterogeneous; it confines the Urban Designer to site specific work rather than allowing concentration on the whole urban system. Urban Designers at the London Docklands Development Corporation felt that CAD might present some answers to these problems in facilitating an iterative, interactive briefing process which could respond quickly to change; whereby varying options for development could be investigated fully but quickly and resource-efficiently; which could be used to communicate design ideas effectively to non-professionals; which could help to make negotiation with developers more effective, less confrontational; which could deal with large, complex sites effectively. The idea was that a piece of city could be modeled on the computer and an urban design study would then be carried out on it which would test varying options for development, resulting in an outline, but three dimensional, model for an area which could be used in three ways: as a briefing tool, as part of a marketing exercise and as a tool to aid effective negotiation and consultation at the planning stage. A pilot project was carried out on a set of development sites at East India Dock and, following the success of this, a full study was carried at Surrey Quays Centre. The paper describes these projects and discusses both their products and their effect on the developmentprocess as aids in decision making.

title	Architectural Photogrammetry & Knowledge-Base Systems Record & Redevelopment
source	Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary	In redevelopment projects, the purpose of heritage recording is part of an investigative process to achieve understanding about structures so that designers can make the appropriate design decisions. It is desirable to integrate the knowledge of the recording and documentation specialist, who has first-hand knowledge of the building, with the interpretative process of evaluating the building information and making design decisions. New developments in the fields of photogram-metric recording and computer science has led to improved "image understanding". This paper describes research that is the result of exploring the concept of integrating new digital photogram-metric recording processes with an automated expert evaluation tool. The goal of this research is to expedite the acquisition of heritage building information for use by a knowledge-based system capable of providing the designer with building performance evaluations. Photogrammetry records all data as a series of three-dimensional coordinates which make it a natural partner for today's three-dimensional CAD systems. Generating a three-dimensional model of architecturally significant physical forms and details can provide a basis for evaluation, understanding, education, and design. The purpose of knowledge-based systems in construction is to enhance the decision-making process with specialized knowledge and experience. The linkage of CAD databases with knowledge-based systems provides a source of input data, such as a three-dimensional model, significant to a particular problem. This research is a collaborative effort between two groups, the Swiss Federal Institute of Technology in Zurich Switzerland, and the University of Manitoba in Winnipeg, Canada.

title	Interaction with Architectural Cases in a Virtual Design Environment
source	Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary	The prime business of architecture is change through design. While most architects will welcome any tool which supports this activity with minimal effort, they will not embrace a tool which either seems to automate design or requires major efforts to understand and use. Conventional databases - be it in the form of books or computer applications - are normally in a serving function to support the activity of design and to provide reference. Visual databases have a long history in architecture in the form of drawings, photographs and, more recently, computer-captu-red or computer-generated images. Whereas the first computer-based image libraries closely followed the existing paradigm of existing paper-based libraries, new developments both in software and in computing media offer different opportunities. Knowledge-based and case-based descriptions of architectural features increasingly replace the traditional, passive representations. While in the past these images were subject to more or less random interpretations, the new computer-based images are only one representation of a model which includes many other aspects. The visual aspects of a building are thus no longer restricted to the finished drawing, but new representations of the abstractions of a building become possible. True and direct interaction with visually presented objects thus becomes a reality. The paper presents a prototype of a visual database in a virtual design environment in its critical aspects: (i) the architectural content and representation of such a database and the criteria for the cases in it, (ii) the enabling computing and software environment, and (iii) three practical applications. The prototype is presently being implemented in the Architectural Space Laboratory (ASL) in the Department of Architecture at ETh Zurich.

title	Towards Hybrid Technologies for Urban Design: Balancing Reliability, Power and Speed in Decision Support
source	Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary	This paper constructs a theory of decision support system design, based on the three independent concepts of reliability, power and speed borrowed from epistemology. We say that a system is reliable if a large part of its performance is useful or correct, that it is powerful if it performs in a useful way in a variety of situations of interest, and that it is fast if its behaviour is consistently dynamic. An arithmetic calculator, for example, is more reliable than a mathematician, but the latter is more powerful. A programming language is as reliable as a calculator, but the calculator is faster. We use this framework to argue that a successful deployment of decision support technology must take into account the balance between reliability power and speed. We illustrate this approach with the case of a hybrid system for studying urban transportation issues in the Greater Barcelona Region based on land use, contrasting it with more conventional tools such as traditional geographic information systems or traffic analysis software. The hybrid system is shown to sacrifice the reliability and speed characteristic of commercially available software for a powerful set of computational tools developed specifically for the problem at hand. This tradeoff process is formalized using an analysis based on second-order reliability, power and speed concepts. We show that micro-level sacrifices of one of these properties are often inversely correlated with the same characteristics at the macro level. For example, the relatively slow performance of in-house software components on a given project can result in a high level of dynamism in addressing several related projects. We extend the design theory outlined above to a methodology for characterizing decision support systems in general, and argue that the hybrid technologies approach is more likely to result in systems reflecting the user's domain knowledge and skills.

title	Functionally Defining Systems: A Systems Theory Approach to Decision Support
source	Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary	Research into decision making seems to suffer from two related weaknesses. The first is lack of attention for the dynamic nature of the decision process and environment. Research attempts to encompass dynamic features are sparse. The second weakness is the allegation that decision alternatives can be discerned on an a priori basis, thus facilitating the use of a choice rule to pick the 'optimal' or 'satisficing' alternative (this is the basic assumption of the prevailing rationalistic approach of decision modelling). However, the assumption of an a priori conception of alterna-tives is not realistic, since it ignores the fact that the exploration and elaboration of alternatives forms an integral part of the decision process. Although several attempts have been made to overcome these problems, a coherent theory seems to be lacking. This paper explores the possibilities of systems theory as an offset for new decision modelling. A system (in the cybernet-ic sense) is, roughly speaking, a collection of elements related in such a manner that emergent properties (i.e., properties that consist the level of the whole, not at the level of its parts) come about. There are many different approaches to systems theory and not all of these are equally useful for decision research. For our purposes, systems that have 'adaptive' properties are worthwhile because they may encompass dynamic features. Furthermore, the use of adaptive, dynamic systems leads to a solution for the problem of the 'disembodied' conception and choice of alternatives, since the choice options automatically follow from the defined system and may change because of its dynamic nature. The important question is how a system can be defined in order to capture the dynamic nature of decision making. In order to answer this question, the paper starts with a short overview of problems with traditional modelling in decision making and systems theory. Next, it will be argued that the crux of defining systems that capture dynamics is to define them 'functionally', i.e. regarding the goals that enter the decision process. An outline of a method to do this will be given. In the last part, the consequences for computerized decision support will be stated.

title	Ecological Validity of Real Scale Models
source	Beyond Tools for Architecture [Proceedings of the 5th European Full-scale Modeling Association Conference / ISBN 90-6754-375-6] Wageningen (The Netherlands) 6-9 September 1994, pp. 31-40
summary	Space simulation is a technique employed by architects, urban designers, environmental psychologists and other related specialists. It is used for academic and research purposes, as an aid to evaluate the impact that the built environment or that to be built would yield in potential or real users. Real Scale Model is organized as one of the models which represents more reliable spatial characteristics in space simulations. However, it is necessary to know the ecological validity of the simulations carried out, that is the degree in which laboratory results could be taken as reliable and representative of real situations. In order to discover which variables of the model used are relevant so that their perception results ecologically valid in respect to reality, a research has been designed in which simulations of specific spaces are appraised both in real space and in the real scale model. The results of both evaluations were statistically analyzed and it shows no significative differences in psychological impressions between the evaluation of real spaces and real scale model. These ecological validation of the real scale model could be of great use to estimate the validity of the results obtained in spaces simulated in the laboratory.

title	A Hypermedia Model for Supporting Energy Design in Buildings
doi	https://doi.org/10.52842/conf.acadia.1994.039
source	Reconnecting [ACADIA Conference Proceedings / ISBN 1-880250-03-9] Washington University (Saint Louis / USA) 1994, pp. 39-49
summary	Several studies have discussed the limitations of the available CAAD tools and have proposed solutions [Brown and Novitski 1987, Brown 1990, Degelman and Kim 1988, Schuman et al 1988]. The lack of integration between the different tasks that these programs address and the design process is a major problem. Schuman et al [1988] argued that in architectural design many issues must be considered simultaneously before the synthesis of a final product can take place. Studies by Brown and Novitski [1987] and Brown [1990] discussed the difficulties involved with integrating technical considerations in the creative architectural process. One aspect of the problem is the neglect of technical factors during the initial phase of the design that, as the authors argued, results from changing the work environment and the laborious nature of the design process. Many of the current programs require the user to input a great deal of numerical values that are needed for the energy analysis. Although there are some programs that attempt to assist the user by setting default values, these programs distract the user with their extensive arrays of data. The appropriate design tool is the one that helps the user to easily view the principal components of the building design and specify their behaviors and interactions. Data abstraction and information parsimony are the key concepts in developing a successful design tool. Three different approaches for developing an appropriate CAAD tool were found in the literature. Although there are several similarities among them, each is unique in solving certain aspects of the problem. Brown and Novitski [1987] emphasize the learning factor of the tool as well as its highly graphical user interface. Degelman and Kim [1988] emphasize knowledge acquisition and the provision of simulation modules. The Windows and Daylighting Group of Lawrence Berkeley Laboratory (LBL) emphasizes the dynamic structuring of information, the intelligent linking of data, the integrity of the different issues of design and the design process, and the extensive use of images [Schuman et al 19881, these attributes incidentally define the word hypermedia. The LBL model, which uses hypermedia, seems to be the more promising direction for this type of research. However, there is still a need to establish a new model that integrates all aspects of the problem. The areas in which the present research departs from the LBL model can be listed as follows: it acknowledges the necessity of regarding the user as the center of the CAAD tool design, it develops a model that is based on one of the high level theories of human-computer interaction, and it develops a prototype tool that conforms to the model.

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	Virtual Worlds: No Interface to Design
source	Cyberspace - First Steps, M.Benedikt ed, MIT Press
summary	In a virtual world, we are inside an environment of pure information that we can see, hear, and touch. The technology itself is invisible, and carefully adapted to human activity so that we can behave naturally in this artificial world. We can create any imaginable environment and we can experience entirely new perspectives and capabilities within it. A virtual world can be informative, useful, and fun; it can also be boring and uncomfortable. The difference is in the design. The platform and the interactive devices we use, the software tools and the purpose of the environment are all elements in the design of virtual worlds. But the most important component in designing comfortable, functional worlds is the person inside them. Cyberspace technology couples the functions of the computer with human capabilities. This requires that we tailor the technology to people, and refine the fit to individuals. We then have customized interaction with personalized forms of information that can amplify our individual intelligence and broaden our experience. Designing virtual worlds is a challenging departure from traditional interface design. In the first section of this chapter I differentiate between paradigms for screen-based interface design and paradigms for creating virtual worlds. The engineer, the designer, and the participant co-create cyberspace. Each role carries its own set of goals and expectations, its own model of the technology's salient features. In the second section of the chapter I address these multiple perspectives, and how they interrelate in the cooperative design process. In conclusion, I consider broader design issues, including control, politics, and emergent phenomena in cyberspace.

title	Historical Background of the Visual Simulation Models in Architectural Design
source	Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary	It is well known that every sort of visualization model has its own capacity to represent the reality and designers' concepts of space. To the authors' knowledge, there are very few attempts to measure and compare their relative potential power of presentation. Given this lack of academic studies, it would be necessary to give a historical background on the use of visual models. Basically those tools could be divided into two main types : traditional visula techniques such as drawings , scale models and most advance technological tools ranging from basic slidesand films to recentlydeveloped techniquessuch as relatoscope, and computer aided simulation models. This paper covers the historical background of visual models .

title	Base de datos de la arquitectura moderna de la ciudad de Maracaibo 1920-1990 [Database of the Modern Architecture of the City of Maracaibo 1920-1990]
source	SIGraDi 2002 - [Proceedings of the 6th Iberoamerican Congress of Digital Graphics] Caracas (Venezuela) 27-29 november 2002, pp. 133-139
summary	Bases de datos, Sistemas y Redes 134The purpose of this report is to present the achievements obtained in the use of the technologies of information andcommunication in the architecture, by means of the construction of a database to register the information on the modernarchitecture of the city of Maracaibo from 1920 until 1990, in reference to the constructions located in 5 of Julio, Sectorand to the most outstanding planners for its work, by means of the representation of the same ones in digital format.The objective of this investigation it was to elaborate a database for the registration of the information on the modernarchitecture in the period 1920-1990 of Maracaibo, by means of the design of an automated tool to organize the it datesrelated with the buildings, parcels and planners of the city. The investigation was carried out considering three methodologicalmoments: a) Gathering and classification of the information of the buildings and planners of the modern architectureto elaborate the databases, b) Design of the databases for the organization of the information and c) Design ofthe consultations, information, reports and the beginning menu. For the prosecution of the data files were generated inprograms attended by such computer as: AutoCAD R14 and 2000, Microsoft Word, Microsoft PowerPoint and MicrosoftAccess 2000, CorelDRAW V9.0 and Corel PHOTOPAINT V9.0.The investigation is related with the work developed in the class of Graphic Calculation II, belonging to the Departmentof Communication of the School of Architecture of the Faculty of Architecture and Design of The University of the Zulia(FADLUZ), carried out from the year 1999, using part of the obtained information of the works of the students generatedby means of the CAD systems for the representation in three dimensions of constructions with historical relevance in themodern architecture of Maracaibo, which are classified in the work of The Other City, generating different types ofisometric views, perspectives, representations photorealistics, plants and facades, among others.In what concerns to the thematic of this investigation, previous antecedents are ignored in our environment, and beingthe first time that incorporates the digital graph applied to the work carried out by the architects of “The Other City, thegenesis of the oil city of Maracaibo” carried out in the year 1994; of there the value of this research the field of thearchitecture and computer science. To point out that databases exist in the architecture field fits and of the design, alsoweb sites with information has more than enough architects and architecture works (Montagu, 1999).In The University of the Zulia, specifically in the Faculty of Architecture and Design, they have been carried out twoworks related with the thematic one of database, specifically in the years 1995 and 1996, in the first one a system wasdesigned to visualize, to classify and to analyze from the architectural point of view some historical buildings of Maracaiboand in the second an automated system of documental information was generated on the goods properties built insidethe urban area of Maracaibo. In the world environment it stands out the first database developed in Argentina, it is the database of the Modern andContemporary Architecture “Datarq 2000” elaborated by the Prof. Arturo Montagú of the University of Buenos Aires. The general objective of this work it was the use of new technologies for the prosecution in Architecture and Design (MONTAGU, Ob.cit). In the database, he intends to incorporate a complementary methodology and alternative of use of the informationthat habitually is used in the teaching of the architecture. When concluding this investigation, it was achieved: 1) analysis of projects of modern architecture, of which some form part of the historical patrimony of Maracaibo; 2) organized registrations of type text: historical, formal, space and technical data, and graph: you plant, facades, perspectives, pictures, among other, of the Moments of the Architecture of the Modernity in the city, general data and more excellent characteristics of the constructions, and general data of the Planners with their more important works, besides information on the parcels where the constructions are located, 3)construction in digital format and development of representations photorealistics of architecture projects already built. It is excellent to highlight the importance in the use of the Technologies of Information and Communication in this investigation, since it will allow to incorporate to the means digital part of the information of the modern architecturalconstructions that characterized the city of Maracaibo at the end of the XX century, and that in the last decades they have suffered changes, some of them have disappeared, destroying leaves of the modern historical patrimony of the city; therefore, the necessity arises of to register and to systematize in digital format the graphic information of those constructions. Also, to demonstrate the importance of the use of the computer and of the computer science in the representation and compression of the buildings of the modern architecture, to inclination texts, images, mapping, models in 3D and information organized in databases, and the relevance of the work from the pedagogic point of view,since it will be able to be used in the dictation of computer science classes and history in the teaching of the University studies of third level, allowing the learning with the use in new ways of transmission of the knowledge starting from the visual information on the part of the students in the elaboration of models in three dimensions or electronic scalemodels, also of the modern architecture and in a future to serve as support material for virtual recoveries of some buildings that at the present time they don’t exist or they are almost destroyed. In synthesis, the investigation will allow to know and to register the architecture of Maracaibo in this last decade, which arises under the parameters of the modernity and that through its organization and visualization in digital format, it will allow to the students, professors and interested in knowing it in a quicker and more efficient way, constituting a contribution to theteaching in the history area and calculation. Also, it can be of a lot of utility for the development of future investigation projects related with the thematic one and restoration of buildings of the modernity in Maracaibo.

title	A Proposal for a Framework for Business Re-engineering in Design and Realization of Artificial Environments
source	Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary	According to the Top-Down design process', this paper gives a generic and qualitative description of a Concurrent Engineering Environment, that should support the problem solving procedure in town planning and architecture in a modern quality oriented society. A system that is based on the principal of democracy might guarantee the preservation of quality in the projection and realization of artificial environments. This environment can be seen as a part of the today often discussed "digital democracy", which practically is based on a infrastructure of computers, interfaces, software systems, a network, databases and a data presentation, that is able to comprise the expectations of professionals involved in the architecture and town planning process. The paper will discuss what the role of the designer and coordinator of this computer environment looks like,in order to design, plan, build and coordinate activities for the realization of this Concurrent Environment and how several software engineers work concurrently to develop tools that guarantee a modular integration. The backbone of this environment is the definition and use of standards for data exchange. Basically those standards are derived from two domains: artifacts will be described in a product model data, while natural resources are described in spatial data. Town planning has to integrate both models. It will be discussed briefly how far the data modelling language EXPRESS of part 11 of the ISO 10303 (Express Language Reference Manual) might be useful to model GIS related problems. An example will describe how a scenario of activities, from registration of real world data to recognition of requirements of society, the definition of development plans through design(competition), lawfulness checking and construction until demolition should look like.
