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	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	Mastering Urban Network Intersection And Superimposition, in an Object-oriented Knowledge System Integrating Rules, Neurons and Processes
source	Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary	Many networks cover the urban texture, either superimposed at a variable distance, or really intersecting, or even in interconnection. We briefly recall the HBDS model, working on persistent abstract data types associated to graphical representations and carrying algorithms expressing conditions to be verified and/or actions to be performed. HBDS is an integrated system too, including database, expert system dealing with fuzzy rules and facts, discrete simulation engine, and neural engine; it has a general purpose programming language. Any urban network is associated to a given prototype, according to the same scheme named prototype with more specific components. These prototypes allow to build the different thematic structures instantiations of the prototypes. All possible cases of arc intersection or "pseudo-intersection" (simple superimposition)or interconnection are obtained by, owing to new prototypes. Moreover, such (pseudo)-intersections are automatically recognized and processed without a human intervention, owing to classes ofconstraints and classes of rules. They deal with particular constraints concerning the location of some urban furniture, and rules concerning the way a cable or a pipe must follow according to thepre-existing other networks in a given area, the minimal distances, minimal or maximal depths, and some required equipments. Urban classes of (pseudo-)intersections inserted in the hyperciass"neuron", inheriting of neural features, may be used for automated learning of urban knowledge; owing to their "behavior", these neurons can communicate and perform actions on other components. Urban classes inserted in the hyperciass "process" may be used for building very large models simulating complex urban phenomenons, thus allowing a better understanding of the real phenomenons. As a conclusion, we emphasize the methodological aspects of object-oriented integration for an efficient processing of the urban context, based on prototyping and mixing rules, neurons and processes.

title	Innovative Expert Systems With Hypertextual User Interfaces: A Special Support for the Building Recovering Project
source	Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary	In this paper, first of all a short account on the peculiarity of knowledge in the domain of Architectural and Building Project, particularly in the Building Recovering Project is given. Thatmeans to focus the concept of "degree of authority" of different types of knowledge with regard to project: regulations; specialist literature having in practice the value of self-regulation; technical updating; exemplary design cases; warnings; analysis methods; heuristics; orientating references. Consequently, the different roles of two basic design & decision support systems, that is expert systems and hypertexts, are considered. The former seem to be quite fit for representing information and knowledge linked to a clear "authority", the one of experts in a certain domain; the latter seem to be quite fit for illustrating the interdisciplinary complexity, different historicinterpretations, various analogous references, and so on. Afterwards, the limits of expert systems based on the logic "true-false" are underlined, and the perspective of expert systems based on more sophisticated and appropriate rules and metarules is proposed. At last, the possible structure of such an innovative expert system, with a hypertextual interface, in the domain of Building Recovering Project is exemplified.

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	Energy Related Design Decisions Deserve Simulation Approach
source	Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary	Building energy consumption and indoor climate result from complex dynamic thermal interactions between outdoor environment, building structure, heating, ventilating and air-conditioning (HVAC) system and occupants. Apart from a few trivial relations, this reality is too complicated to be casted in simple expressions, rules or graphs. As shown in a previous paper, there are now tools available - in the form of computer simulation systems - which treat the building and plant as an integrated, dynamic system. It is argued that these can and should be used in the context of design decision support and design evaluation related to thermal energy. The paper will give ageneral overview of building energy design tools which range from simplified design tools (SDT's) to comprehensive modelling and simulation systems. It will be demonstrated why SDT's are very limited in scope and range of applicability. With respect to building energy simulation the paper will compare simplified models with comprehensive models in terms of ressource needs, applicability etc. In view of the risk involved when using SDT´s or simplified models, the paper strongly promotes the use of comprehensive tools in combination with emerging intelligent front ends. The message ofthe paper will be: let the machine do the work.

title	An Outline of the Requirements for a Computer Supported Collaborative Design System
source	Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary	Computer-Aided Architectural Design (CAAD) systems have adequately satisfied several needs so far. They have dramatically improved the accuracy and consistency of working drawings, enabled designers to visualize their design ideas in three-dimensions, allowed the analysis of designs through data exchange and integrated databases, and even allowed the designers to evaluate (and in some cases generate) designs based on comparisons to previous cases and/or the formalization of specific rules and grammars. Yet, there is a general consensus that CAAD systems have not yet achieved their full potential. First, most systems employ a single-user approach to solving architectural problems which fails to grapple with the fact that most design work is done through teamwork. Second, current systems still cannot support early design stages which involve client briefing, data collection, building program formulation, and schematic design generation. Thus, if CAAD is to ultimately benefit the design process, it must (1) emulate and support the design team approach to architectural problem solving and (2) be deployed in the earliest possible stages of the design process. This paper seeks to study remedies to both of the afore-mentioned limitations through focusing on the interaction between a set of requirements (the building program) and the architectural solution that satisfies them (the schematic design). The core of this interaction forms the fundamental dialectic and collaborative nature of what is called designing: a concerned social activity that proceeds by creating architectural elements to address a set of requirements and their re-thinking as a result of architectural conjecture. To investigate this relationship, it is proposed to build a computer-supported collaborative design environment using the tools of conceptual modelling (based on the NIAM notation), object-oriented algorithms, and distributed agents. Based on a literature survey and earlier findings on the role of artifacts in collaborative design, this paper outlines the requirements for the above system and reports on initial experiments. Thus, it constitutes the first stage of a research project that will lead to a full implementation of a distributed collaborative computer environment addressing the above issues.

title	Abstract Modelling - Forming and Exploring
source	The Virtual Studio [Proceedings of the 12th European Conference on Education in Computer Aided Architectural Design / ISBN 0-9523687-0-6] Glasgow (Scotland) 7-10 September 1994, p. 214

summary	Architectural design is always concerned with form to things. It is the sphere or action where meanings are to be expressed and further on - received (by a receiver), felt, understood. "Meanings" mean not only rational information. The matter is to reach the essence and to master ways appropriate to expose and interprete it. Quality of the form decides whether architectural or any work is worth attention or not and to what degree. Form is an attribute of a thing. It is form that "speaks". This linguistic metaphore shows one of natural, inborn features of things and states. However, questions appear: 1. Does everything have form? 2. Is the form an objective term? 3. What limitations of the definition of the form to accept- if any? The friendly environment for creating form consists of conscious intentions plus open mind. Rules are certain, but liquid. Every formal communication system may be widened individually. The only limitation is to be received according to intentions. So, incredibly, the infinite number of combinations, even within one system, may be possible.

title	Urban Configuration, Attraction And Morphology
source	Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary	Spatial Interaction (SI), based on the principle of attraction, has set up a powerful way of looking at the behaviour of urban systems. Within-place activities generate and/or attract trips, due to their inner fragmentary nature; several activities articulate a system of locations and flows which is supposed to be regulated by concentration of those activities and distance between them'. SI has been criticized for having a poor theory and little regard to spatial specifics. In general terms, planners and large-scale urban scientists have been more comfortable with it than designers and urban morphologists, whose questions about space configuration are awkwardly dealt with in such a framework. Recently, Space Syntax (SS) has been suggested as an alternative to describe possible roles of space in the urban system. Its theory looks very complex - a deep cultural, anthropological connection between man and space, an atavistic impulse driving the shaping of space. Teklenburg et al have shown, however, that it is, in fact, very simple and not far from the rude assumptions of SI: a matter of distance and orientation3. Hence, what does look new is just its way of describing orientation, through the axiallity of public space. Axial lines retain the fundamental issue of connectivity; so they describe space more efficiently than the traditional zones or links used in SI models. SI says little about configuration, SS says little about interaction between spaces and activities, and both say nothing about morphology, or the configurational development of urban systems. An alternative approach is suggested: (i) urban spatial configurati-on (urban grid and built form) strongly conditions activity location and flows, in the short term. In this way, a convenient description of such a configuration should denounce its potential to housing activities and generate flows. This required description should take the grid axiallity as a measure of connectivity and orientation, as in SS, as well as the built form as a measure of attraction, as in SI; (ii) activity location and flows strongly conditions urban spatial configuration change, in the long run. Location and flow patterns create values that are expressed by an increasing conflict between rising land values and declining building values. As a result, configuration is taken as a particular state of a morphology whose transformation rules are an economic expression of spatiality. Flows are cause and effect in the lagged process of mutual transformation which shapes the urban space.

summary	Our young students have no strong bindings to the tools and methods of our profession. With their open-minded access to the media, they often try to do things, which are surprising and new. Things which would have been impossible to think of without a computer. They are inspired of apparently unknown design-options, which they find in CAD-tools, or they are exploring possibilities in 'strange' combinations of media, not unknown from Television-commercials and music-videos. This Blitz-session will show some students' projects in a very short while. The common thing is, that the students have broken rules, that the teacher never realised were rules, because of his (my) traditional education. One student uses a solid modelling -tool for inspiration, - another uses an auto-tracing tool to generate the concept - and a group of students used a combination of video, grabbing and 3D-modelling to generate new architecture.

title	Applying Visual Design: Trade Secrets for Elegant Interfaces TUTORIALS
source	Proceedings of ACM CHI'94 Conference on Human Factors in Computing Systems 1994 v.2 pp. 353-354
summary	This tutorial describes a number of fundamental techniques applied routinely in communication-oriented visual design. The orientation, process, training, and culture of the visual design disciplines (graphic design, industrial design, interior design, architecture) are essential components of effective interface design. Unfortunately, few software developers or human factors engineers receive any training in these disciplines. This tutorial describes important design rules and techniques internalized by every visual designer through coursework and studio experience. While mastery will indeed require extended practice, the techniques we describe are not difficult to understand and can be immediately applied to real-world problems. We draw our background, training, and influence from the rational, functional, information oriented perspective of the Modernist design ethic. Because all graphical user interfaces are communication systems, we believe their design should reflect these same values. Our tutorial is organized not along the traditional subdisciplines of color, typography, or ideation, but along the problems of graphical interface design as experienced in commercial software development. We describe basic design principles (the what and why), common errors, and practical techniques (the how) for each of the six major areas outlined below. (1) Elegance and Simplicity (2) Scale, Contrast and Proportion (3) Organization and Visual Structure (4) Module and Programme (5) Image and Representation (6) So What About Style?

title	An Information Model of Energy Performance in Early Building Design
source	Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary	Design is a creative and dynamic process. The level to which a future generation of Intelligent Integrated Building Design Systems will be able to support this process depends on the power of the underlying conceptual models to cover the semantics of design. In the definition of generic building models, the concept of constraints appears to be a powerful means to formalize those semantics. Both design performance goals, and rules and relations in design composition can be described as constraints. The Engineering Data Model (EDM), recently developed at UCLA, acknowledges this fact. It allows the formal definition of object oriented building models, using constraints as the central concept for describing relations. This paper will discuss the development of an EDM building model for the integrated design for energy performance, and the implementa-tion of this model in a small prototype system. We will specifically deal with modelling informati-on in the early design stages. This information typically consists of multiple global design alternatives on one hand, and a wide range of conflicting design goals on the other hand. In the paper, it is demonstrated that integration of these conflicting views on building performance in one coherent model is the key to obtaining an optimal design result. Using the Dutch building codes for energy performance (NEN 2916) as an example of design goals, the concepts and relations of these building codes were translated to a formal EDM model. A small shell was built on top of this computer-interpretable model, to demonstrate the useability of the model during the solving of a concrete design problem. It is shown that the EDM building model is able to provide the designer with integrated information through combining different sets of performance constraints and design alternatives in one environment.

source	Terry Knight, Transformation in Design: A Formal Approach to Stylistic Change and Innovation in the Visual Arts, Cambridge University Press, 1994, 258 p.
summary	Shape grammars are languages of two- and three-dimensional forms analogous to spoken languages. A great deal of attention has been centered on them as a basis for supporting design with computers. They are sets of rules which can be used to create families of visually related designs. Each design, in the family of possible designs that can be created by a set of rules, is generated by successively applying rules from the set to the current state of a design until no more rules are applicable. A rule may be applied if certain shapes specified by the rule exist in the current state of the design. After application of a rule, the specified shapes are substituted with one or more replacement shapes specified by the rule thereby adding, subtracting or modifying shapes in the current design. From a single initial state many alternative designs can be generated because there is usually more than one applicable rule at any stage.

title	Form and Performance in Intelligent CAAD Systems for Early Stages in Solar Design Building
source	Technion, Faculty of Architecture and Town Planing, Haifa
summary	Great care should be taken at the initial design stages to determine the principles and solution schemes for climate and energy-conscious buildings. The present study deals with supporting the designer's efforts at the early stages to lay down the appropriate principles for a conceptual and geometric design of energy-preserving buildings, which are also thermally comfortable and adapted to local climatic conditions. For years, especially during the last decade, important data concerning climate-conscious construction has been compiled, but the information has not been utilized by designers, due to its inaccessibility. It is significant, though, that solutions based on this knowledge could be found and assessed at the preliminary design steps. A correct climate-conscious design conceived at the initial stages may guarantee that during later phases of the project's development no problems calling for essential and drastic changes in the basic design will crop up. The meaning of such changes at later stages may require sometimes a redesigning of the entire project. It is vital, therefore, to understand at the pre-conceptual phase, what are the correct climatic-solar design strategies which satisfy the requirements of the local conditions, and enable the attainment of thermal comfort conditions, while consuming the least possible energy. The present study proposes a computer-aided passive solar design system (PASYS) which enables the handling of entire designing process, and its general, conceptual aspects, as well as the preliminary designing steps and their particular, practical aspects. The system is based both on a knowledge base which stores the existing information concerning solar-climatic construction in the form of rules of thumb, and on precise procedural models which enable finding solutions suited to the local climatic conditions. The proposed system is an intelligent CAAD system which equips the designer who is aware of the constraints of climate and energy, with a tool to achieve a better design. PASYS was developed as a universal system to deal with the various activities involved in the initial – pre-conceptual and conceptual - design stages. The system supports the following design activities of each stage of this kind: analysis, synthesis, documentation, assessment and decision making. It is capable of analyzing given conditions, thus helping the designer understand which are the significant preliminary design stages that have a bearing on thermal comfort conditions in a given climate. The system is also capable of proposing solutions corresponding with the particular design phase, and assess their adequacy. These solutions take into account the constraints determined both by the designer and by the system itself, owing to the knowledge base it contains. The system can also document the various solutions that have been found and selected, so that may be further developed at later stages. This documentation is carried out by a graphic interface, developed as part of the system, as well as by an interface devised for existing CAD software. This study highlights the interaction between form and performance. The system is able to assess the performance of a proposed design by considering a given geometry (form), or viceversa, it is able to recommend a solution that can deliver desired and required performances. The study comprises three parts: (a.) Development of the conceptual model of a knowledge based design process. (b.) Further development of the initial stages of the afore mentioned process, including the pre-conceptual and conceptual stages. (c.) Demonstration of the mode of work with the PASYS system. // The first part of the study deals with the definition of the design process, the definition of the various design steps and their characteristics, and the definition of the activities involved in each design step. This part of the work also presents the kinds of knowledge bases affecting the design process, and shows how this knowledge is an inseparable part of the design process. The second part deals with the development of the initial design stages - the pre-conceptual and the conceptual - which are based on knowledge. This part also contains compiled knowledge that is relevant to the design stage, and a knowledge storage and retrieval method that was developed so as to make the knowledge available and accessible on demand. This part further presents precise procedural methods, developed to find solutions adapted to the specific given conditions, and to precisely assess the performance of the proposed solution. A case in point is the module of the SHADING system which enables a precise assessment of the mutual shading of buildings, and an examination of the exposure of the southern elevation to the sun, which is necessary in order to determine the effective solar absorption area in a proposed project in given environment conditions. The third part of the study demonstrates the solar-climatic design process put into action and supported by the system that was developed. This system enables the designer, even at the preliminary design stages, to determine which properties relating to local climatic conditions he will introduce into the building. This important, seemingly natural act, is usually performed during more advanced stages, when it might generate significant changes in the design, at a juncture when changes are hard to make. A PASYS-aided design environment ensures that from the beginning of the designing process, the project will be designed correctly and efficiently as far as energy is concerned.

title	Analysis of design communication with and without computer mediation
source	Proceedings of Co-designing 2000, pp. 329-337
summary	With recent developments in CAD and communication technologies, the way we visualise and communicate design representations is changing. A matter of great interest to architects, practitioners and researchers alike, is how computer technology might affect the way they think and work. The concern is not about the notion of 'support' alone, but about ensuring that computers do not disrupt the design process and collaborative activity already going on (Bannon and Schmidt, 1991). Designing new collaborative tools will then have to be guided by a better understanding of how collaborative work is accomplished and by understanding what resources the collaborators use and what hindrances they encounter in their work (Finholt et al., 1990). Designing, as a more abstract notion, is different than having a business meeting using video conferencing. In design it is more important to 'see' what is being discussed rather than 'watch' the other person(s) involved in the discussion. In other words the data being conveyed might be of more importance than the method with which it is communicated (See Kvan, 1994). Similarly, we believe that by using text instead of audio as a medium for verbal communication, verbal representations can then be recorded alongside graphical representations for later retrieval and use. In this paper we present the results of a study on collaborative design in three different environments: face-to-face (FTF), computer-mediated using video conferencing (CMCD-a), and computer-mediated using "talk by typing" (CMCD-b). The underlying aim is to establish a clearer notion of the collaborative needs of architects using computer-mediation. In turn this has the potential in assisting developers when designing new collaborative tools and in assisting designers when selecting an environment for a collaborative session.

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	Psychology of Early Design in Architecture
source	Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary	Lately there has been a good deal of emphasis on the early stages of the design process, particularly by developers of computer aids and quantitative design models for both evaluation and generation of designs in a variety of domains. Yet, there is little understanding of the early design-process. While the early design process as manifested by human designers need not be the sole basis of the description of this phase, it certainly represents and important kernel of knowledge, especially for those who are interested in developing models, systems or merely interfaces for such systems. This paper focuses on the characterization of the psychology of the early design phase in architecture. It is described in terms of the general design strategies and problem solving tactics used; and is contrasted against some of the process characteristics that

title	A Hypermedia Model for Supporting Energy Design in Buildings
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	Spatial Analysis for Museum Design
source	The Virtual Studio [Proceedings of the 12th European Conference on Education in Computer Aided Architectural Design / ISBN 0-9523687-0-6] Glasgow (Scotland) 7-10 September 1994, pp. 201-206
doi	https://doi.org/10.52842/conf.ecaade.1994.201
summary	The paper describes how a specially written customisation of AutoCAD enables students of Architecture to use the method of spatial analysis called Space Syntax developed by Professor Bill Hillier of the Bartlett School of Architecture, London, to examine a number of existing museums, to compare the findings against other criteria, and to draw conclusions about the strategy adopted in museum design. Simple interactive graphics enable plans to be entered and compared, so that they may be evaluated during the design process, with decisions supported by objective tests. This improves both design decisions and the learning process.

title	A run time exchange of component information between CAD and object models: A standard interface
source	The Int. Journal of Construction IT 2(2), pp. 37-52
summary	Integrated computer aided design could only occur in engineering once CAD systems could represent physical features and components rather than graphical primitives. In most dedicated CAD systems, the knowledge of a complete component exists only for the duration of each drawing command and the data stored in the database is simply a set of graphic primitives. This paper proposes an approach for real time information transfer from and to CAD systems based on a high level object representation of the design drawing. Drawing components are automatically identified and represented in an object hierarchy that reflects the 'part-of' relation between the various components including building spaces. Such hierarchies transfer an industry standard CAD system i.e. AutoCAD, into a high level object oriented system that can communicate with external applications with relative ease.
