title	Changing trends and approaches in human and computer modelling for social housing policies
source	Timmermans, Harry (Ed.), Fourth Design and Decision Support Systems in Architecture and Urban Planning Maastricht, the Netherlands), ISBN 90-6814-081-7, July 26-29, 1998
summary	The paper discusses conceptual issues, goals and preliminary results of an on-going research which aims at building a Decision Support System for public housing environmental oriented maintenance and management in a city in Southern Italy, Bari. Traditional post-war Italian housing policies are compared with more recent approaches in the field, pointing out the change from quantitative, aggregated, more simple building problems and relatedapproaches to qualitative, differentiated, complex ones integrating social, economic and environmental dimensions with the aim of regenerating deteriorated residential areas. The paper claims for the need shift, both in the human and computer areas, from traditional quantitative models to new approaches able to manage also qualitative variables, temporal dynamics, emergencies, and intentionality, since they appear key aspects of the real world to be modelled. The housing estate of Bari and its needs of maintenance and management are examined, eliciting essential related knowledge using the interview technique. The clear orientation towards sustainable policies for urban regeneration, at a local, national, and Community level, is also considered. The innovative and collaborative nature of such policies and the attention to be paid to the social aspects ofthe problem require a complex DSS, integrating various kind of hypertexts, information systems and case-based fuzzy expert systems, whose main aims, functions, software and general organisation are outlined in the paper.

title	Making Models Architectural: Protean Representations to Fit Architects’ Minds
source	Digital Design Studios: Do Computers Make a Difference? [ACADIA Conference Proceedings / ISBN 1-880250-07-1] Québec City (Canada) October 22-25, 1998, pp. 354-365

summary	A rich vocabulary has evolved for describing architecture. It serves not only as a means of communication, but also as an embodiment of concepts relating to form, space, structure, function, mood, and symbolism. We architects not only speak in terms of walls, rooms, roofs, arches, etc., we see in terms of them and think in terms of them, as well. Such concepts are integral to our ability to design. Typical CAD representations, however, are based on geometric/mathematical elements like points, lines, planes, and symbols. Even more experimental approaches like parametric shapes or procedural assemblies correspond poorly to architectural elements, and seldom lend themselves well to making conceptual changes that would allow exploration of design alternatives. Small wonder some architecture schools experience a division between computer and studio courses, or even between computer and studio faculty. Different ways of talking and thinking are involved. The concepts involved are often mutually exclusive. This paper discusses an attempt to address this conceptual mismatch, using what are termed “protean” (meaning “very changeable”) elements. These are high-level elements corresponding to architectural concepts like “wall,” or “dome.” They each have parameters appropriate for the particular type of element they represent, and produce the polyhedra necessary for graphics based on these parameters. A system is being implemented to allow models to be constructed using these elements. The protean elements form a loosely structured model, in which some elements hierarchically contain others, and some elements are essentially freestanding, being created and manipulated independently of other elements. Characteristics of protean element are discussed, including the underlying object-oriented structure, the relationship between elements and graphics, and functions associated with the objects. A scheme is explained whereby all parts of a design can be represented even when the design includes extremely unusual forms not conforming to predictable classes of elements. The necessary support framework is also discussed; general flow of the system and mechanisms for viewing the model and editing subcomponents are explained. The current status of the project, and intentions for future work are discussed. The project has been partially implemented, and the necessary framework to support the system is mostly complete.

title	Information systems and the Internet: towards a news counter-revolution?
source	Timmermans, Harry (Ed.), Fourth Design and Decision Support Systems in Architecture and Urban Planning Maastricht, the Netherlands), ISBN 90-6814-081-7, July 26-29, 1998
summary	The explosive evolution of the Internet into a ubiquitous infrastructure influences the generation, dissemination and use of information. From a historical perspective it redefines issues that have been central to the news and information industry since the seventeenth century. One such issue is periodicity. The practicalities of news media and news as a commodity have resulted into the periodical appearance of news and, by extension, of all actual information. Integral to periodicity iscontrol of information production by institutions or other authorized channels. With the advent of the Internet we are reverting to an a-periodical information system characterized by personalization anddirect contact between information provider and information user. Rather than relying on the institutional status of the propagation channels, we are increasingly evaluating information quality by the integrity, up-to-datedness and reliability of its source. Moreover, we are able to complement orcorroborate information by linking different sources together in compound representations. The extent and complexity of the Internet make search intermediaries necessary. These collect and collate information either ad hoc (responding to a user query) or as part of wider documentation projects. These projects re-introduce institutionalization but the autonomous, intelligent mechanisms used by such intermediaries promote personalization in information retrieval and facilitate decentralization ofinformation supply into a cottage industry. In addition to a-periodicity, directness and wider availability of information, decentralization provides a new social and technical context for precedent and case-based approaches in designing.

doi	https://doi.org/10.52842/conf.caadria.1998.317
summary	Architects face a significant lack of computer tools that truly support them in the early, conceptual stages of design. In this paper, we take a look at the reasons for that and propose some solutions. We introduce new human-machine interaction methods that do differ from construction based approaches. We define new spatial interface paradigms as well as new objects and their behavior. Finally we present their implementation in ‘Sculptor’ - a modeling prototype to enable designing in space with space.

title	Neutral intelligent CAD communication: information exchange in construction based upon a minimal schema
source	KTH Stockholm
summary	An improved information exchange is frequently proposed as one solution to the inefficiency problems which the construction industry is suffering from today. Such an improvement is very dependent of the use of information technology, IT. To enable an advanced use of IT, there is a need for integrated project communications frameworks and integrated industry wide information. This thesis discusses how product models can be used to improve the information exchange from design to construction. Today there are several approaches to product modelling. Some researchers propose very detailed models whereas others propose generic models with fewer concepts. In this area there is a close connection between research and standardisation, which is carried out by organisations such as the ISO STEP committee and the International Alliance for Interoperability. To get acceptance for a standard proposal, it has to be accepted by both users and standardisation bodies. Thus this research, in addition to the technical requirements on information content and structure, also discusses success factors for standardisation, implementation and usage. In order to define important requirements on a product model for information exchange between design and construction, current research, development and standardisation in the field of product modelling was studied. This thesis advocates a minimal approach in the number of concepts used in a product model, in combination with an external building element classification, following national industry practice. The minimal NICC schema, developed during this research, was tested in a prototype and test study. Three applications were tested: PreFacto (planning tool), Microsoft Project (time scheduling tool) and Calc3(cost estimation tool). From the CAD-system MCAD, NICC files with the building objects were created and transferred into a relational database from which the three applications received their specific input files. The results of the evaluation of the NICC schema and the test study demonstrated that a product model based on few concepts can manage the required information exchange.

title	Consequences of Interdisciplinary Approaches in the Construction ofKnowledge-Bases
source	Timmermans, Harry (Ed.), Fourth Design and Decision Support Systems in Architecture and Urban Planning Maastricht, the Netherlands), ISBN 90-6814-081-7, July 26-29, 1998
summary	The character of interdisciplinarity in planning approaches create a new, intriguing, emerging complexity (Funtowitcz and Ravetz, 1994) in problems and in knowledge-structuring of contexts of planning practices. The key-role played by information systems (IS) implicates a re-consideration ofcharacter of knowledge to be used in knowledge-bases. The necessity of considering knowledge domains coming from social, cultural, economical, technical, physical and naturalistic approaches means dealing with different scales of value, with non homogenous parameters. The necessity ofmanaging flexible knowledge rises on the fore as fundamental issue for future information system oriented to supporting decisions. Might information systems be useful in this interdisciplinary approach ? It is necessary to contain in a knowledge-base both quantitative and qualitativeinformation ? Three alternatives are available for a conceptual discussion :the possibility of identify new approaches, in order to develop information systems able in managing new knowledge; the necessity of adding new support systems oriented to manage soft knowledge, to traditionalgeographic information systems (GIS); the possibility of non using support systems coming from a technological vision of problem for nontechnical knowledge (Latouche 1996). The first two paragraphs are due to F. Selicato. The third and the fourth paragraph are due to C. Torre.

title	Conjoint Approaches to Developing Activity-Based Models
source	Eindhoven University of Technology, Faculty of Architecture and Urban Planning, The Netherlands
summary	Since the late 1950s, transportation models have played an important role in forecasting travel demand and evaluating the impacts of plans and policies. Planners use transportation models to learn about the behavior of transport systems. Over the past decades, the development of particular modeling approaches has closely followed planning needs, which in turn are closely related to dominant policy issues. The first generation of transportation models was developed during the late 1950s and early 1960s. Their purpose was to facilitate the prediction of future travel demand, such that road capacity programs could be based on predicted demand. The first generation models are commonly referred to as four-step models. These models are typically formulated and calibrated at the level of the traffic zones. Individuals are aggregated by traffic zone. Traffic is considered to be the result of four sequential decisions: trip generation, trip distribution, modal split and traffic assignment. These decisions are modeled separately at successive stages. Although the four-step models have been widely used, even institutionalized in literally thousands of applications (Stopher, et al., 1996), the major shortcoming of these large-scale, aggregate and supply-oriented models is their lack of behavioral content.

title	Extending spatial DSS with spatial choice models of multipurpose shopping trip behaviour
source	Timmermans, Harry (Ed.), Fourth Design and Decision Support Systems in Architecture and Urban Planning Maastricht, the Netherlands), ISBN 90-6814-081-7, July 26-29, 1998
summary	Spatial choice or interaction models have been widely used in spatial DSS or customised GIS for analysing the impacts of retail location plans. The models typically used, however, do not account for spatial agglomeration effects on spatial choice behaviour. This study develops a model system for analysing the impacts of retail plans based on a choice model of multipurpose behaviour developed in earlier work. The model system is implemented in the spatial DSS called Location Planner. An empirical study demonstrates the empirical estimation and use of the model for analysing the impacts of an expansion of floor space in the major shopping centre of a middle-sized city in The Netherlands. The results indicate that agglomeration effects as predicted by the model can have substantial impacts on the performance of retail systems. Therefore, it is argued that when incorporated in a spatial DSS, the more complex models have the potential to improve the use of these systems for impact analysis.

source	Timmermans, Harry (Ed.), Fourth Design and Decision Support Systems in Architecture and Urban Planning Maastricht, the Netherlands), ISBN 90-6814-081-7, July 26-29, 1998
summary	An analysis is made of the relation between the conceptualand paradigmatic level of GIS technologies and the new forms of plan, whichmake environment the center of attention. The intention is to study newcriteria for zoning able to give contextual representations of theterritorial, environmental and landscape aspects of the geographical space,and also to study new legislative principles, able to establish integratedrules for theprojecting of soil uses, the safeguarding and recovery ofenvironmental systems and the tutelage and boosting of the landscape. The experimentation of GIS (Geographical Information System)technologies aims at the construction of systems helping to make decisionsfor the control of the environmental and landscape aspects of theterritory. An analysis is made of the ways in which there are formulated thedescriptions of the various aspects of the environment: the conceptsthrough which knowledge is expressed, the languages used forrepresentations, the cognitive models adopted. GIS technologies have made it possible to represent in an explicitmanner the paradigms underlying the various models of knowledge.Specifically, the following cognitive models have been developed:- ecological models of nature- ecological models of human settlement- ecological models of inhabitants’ mental perceptions

source	II Seminario Iberoamericano de Grafico Digital [SIGRADI Conference Proceedings / ISBN 978-97190-0-X] Mar del Plata (Argentina) 9-11 september 1998, pp. 426-431
summary	The Information System of Building Components -ISBC, consists of a set of activities to control the graphic data operation procedures of building plans and its storage in a data base. The system is specially prepared to be used by architects, engineers and cad operators who are dealing with a continuous flow of design problems, regarding the permanent adaptation and modification of office's layout in a great amount of buildings around the country. These constant changes bring out several types of architectural design problems that should be taken into consideration by the proposed system, particularly the reallocation of office furniture and the modification of building components. Therefore, the principal goal of the system is based on the inquiry and permanently updating of the data base composed by: furniture, technical equipment (computers and telecommunications networks), lights, air-conditioning, sanitary equipments and any other equipment that can be inventoried. The generation and operation of great amount of graphics and alphanumerical information bring out severe data inconsistency problems, particularly when graphic data is envolved. The task of "feeding" and modifying a data base produces errors that aren't easy to solve, even when specific consistency procedures are used. The ISBC provides the computer routines for the initial task of building up the required data base of each building, allowing to use an interactive algorithm among the digitized plans of each office and the data base of the enquiry system. An additional operation included in the system allows to compute the area of each section of the building in order to calculate several types of working spaces regarding ergonomical and functional performance specifications established by law regulations.

title	Prototypical Laboratory Design to Support Learning and Teaching
source	Timmermans, Harry (Ed.), Fourth Design and Decision Support Systems in Architecture and Urban Planning Maastricht, the Netherlands), ISBN 90-6814-081-7, July 26-29, 1998
summary	Collaboration between designers and scientists is an unusual combination to undertake the prototypical design of a teaching laboratory funded by Howard Hughes Medical Institute. The zoologists are developing a cooperative learning and interactive teaching pedagogy to make learningscience a process of critical inquiry and discovery. The industrial and interior designers are paying attention to the design issues of function and environmental support for teaching and doing the work required in a three-hour, hands-on beginning science learning space. Using both qualitative andquantitative research methods, the designers are able to determine a framework for making design decisions in prototypical beginning science environments. This framework is being developed as a guideline for designing similar environments at other institutions of higher learning. Videotape analysis precedes the research to uncover the underlying problems of the existing space and to formulate the questions for the research. Elements of a case study and an evaluative study integratewith the design process to form the basis of an intensive investigation of design issues for a beginning science teaching laboratory. Using two pretests as a baseline, the posttest data evaluates the success orfailure of the prototypical design. Both the pretests and the posttest evaluate the physical attributes of the old and new learning environment related to a beginning laboratory course in Zoology at Arizona State University.

doi	https://doi.org/10.52842/conf.acadia.1998.172
summary	Architectural designs are principally represented by drawings. Usually, each drawing corresponds to one design or aspects of one design. On the other hand, one executable drawing corresponds to a set of designs. These drawings are the same as conventional drawings except that they have computer code or programs embedded in them. A specific design is the result of the computer executing the code in a drawing for a particular set of parameter values. If the parameters are changed, a new design or design variation is produced. With executable drawings, a CAD system is also a program editor. A designer not only designs by drawing but also programming. It fuses two activities: the first, drawing, is basic in architectural practice; and the second, progamming, or specifying the relation of outputs from inputs, is basic in computer system development. A consequence of executable drawings is that architectural form is represented by graphical entities (lines or shapes) as well as computer code or programs. This type of architecture we call digital architecture. Two simple examples are presented: first, the design of a building in terms of an executable drawing of the architects, Sangallo the Younger and Michelangelo, and second, a description of an object oriented implementation of a preliminary prototype of an executable drawing system written in 1997 which computes a simple office layout.

title	Evaluating Office Buildings with MOLCA(Model for Office Life Cycle Assessment)
source	Timmermans, Harry (Ed.), Fourth Design and Decision Support Systems in Architecture and Urban Planning Maastricht, the Netherlands), ISBN 90-6814-081-7, July 26-29, 1998
summary	MOLCA (Model for Office Life Cycle Assessment) is a project that aims to develop a tool that enables designers and builders to evaluate the environmental impact of their designs (of office buildings) from a environmental point of view. The model used is based on guidelinesgiven by ISO 14000, using the so-called Life Cycle Assessment (LCA) method. The MOLCA project started in 1997 and will be finished in 2001 resulting in the aforementioned tool. MOLCA is a module within broader research conducted at the Eindhoven University of Technology aiming to reduce design risks to a minimum in the early design stages.Since the MOLCA project started two major case-studies have been carried out. One into the difference in environmental load caused by using concrete and steel roof systems respectively and the role of recycling. The second study focused on biases in LCA data and how to handle them. For the simulations a computer-model named SimaPro was used, using the world-wide accepted method developed by CML (Centre for the Environment, Leiden, the Netherlands). With this model different life-cycle scenarios were studied and evaluated. Based on those two case studies and a third one into an office area, a first model has been developed.Bottle-neck in this field of study is estimating average recycling and re-use percentages of the total flow of material waste in the building sector and collecting reliable process data. Another problem within LCA studies is estimating the reliability of the input data and modelling uncertainties. All these topics will be subject of further analysis.

title	An Experimental Design System for the Very Early Design Stage
source	Timmermans (ed.) Proceedings of the 4th Conference on Design and Decision Support Systems in Architecture and Urban Planning, Maastricht
summary	The concepts of the experimental design system that are discussed are feature modeling and geometrical constraints. The main technique for creating the user environment is Virtual Reality. Feature modeling forms the basis for managing the design data. To start with, data storage is implemented in a Relational Data Base Management System. Along with this a (traditional) interface is developed for managing the data. Data management consists of feature type creation and feature type instancing. Features are used to define building elements, their relationships and additional constraints. Apart from the design data, geometrical data are stored. Possible design solutions can be limited using geometrical constraints. Specifying connection types between building elements result in a set of solutions for the position of the bounding boxes of the building elements in space.

doi	https://doi.org/10.52842/conf.acadia.1998.008
summary	The last thirty years have seen the development of powerful new tools for architects and planners: CAD, 3D modeling, digital imaging, geographic information systems, and real time animated walkthroughs. That’s just the beginning. Based on our experience with CAD tools, analysis of design practice, and an understanding of computer hardware and software, we’re out to invent the next generation of tools. We think architects should be shakers and makers, not just consumers, of computer aided design. We started the Sundance Lab (for Computing in Design and Planning) in 1993 with a few people and machines. We’ve grown to more than a dozen people (mostly undergraduate students) and a diverse interdisciplinary array of projects. We’ve worked with architects and planners, anthropologists, civil engineers, geographers, computer scientists, and electrical engineers. Our work is about the built environment: its physical form and various information involved in making and inhabiting places. We cover a wide range of topics – from design information management to virtual space, from sketch recognition to design rationale capture, to communication between designer and computer. All start from the position that design is a knowledge based and information rich activity. Explicit representations of design information (knowledge, rationale, and rules) enables us to engage in more intelligent dialogues about design. The following describes some of our projects under various rubrics.

source	Timmermans, Harry (Ed.), Fourth Design and Decision Support Systems in Architecture and Urban Planning Maastricht, the Netherlands), ISBN 90-6814-081-7, July 26-29, 1998
summary	Overcoming barriers in the current building process that hinder the realisation of optimal energy efficiency in buildings is the aim of the Energy Impact Knowledge-based System [EIKS] project. During this project, a demo-version of a knowledge based assistive information and decision supportsystem was developed, considering the design and evaluation of integrated daylight and artificial lighting systems for office rooms. Twenty workshops with building experts were carried out in four European countries. The first set of sixteen workshops delivered the specifications of the system.During the second set of four workshops, this prototype was shown to some of the building experts who had attended one of the workshops of the first series. The outcomes of the first series EIKS workshops were very general and not really specifying the EIKS-prototype as expected. However, from the generally enthusiastic response of participants during the second workshop series it can be concluded that the prototype is a good basis for further development.

title	A methodological approach to object modelling in the architectural designprocess
source	Timmermans, Harry (Ed.), Fourth Design and Decision Support Systems in Architecture and Urban Planning Maastricht, the Netherlands), ISBN 90-6814-081-7, July 26-29, 1998
summary	The paper describes a first prototype constructed in search for a central object model. It presents all possible data, concepts and operations concerning the architectural design process in the early phases.A central model of the process of design is essential: going from one design phase into another, the model describes geometrical shapes, abstract concepts like space and activity, concrete physical building elements and the basic operations all these entities undertake. Emphasis is put on combining all these different viewpoints, thus enabling the designer to use a broad range of design strategies. The aim is to help him and not steer or even hamper his creative process. Information necessary toassist the user of the system concerning energy calculation, stability checks etc can be extracted. By means of appropriate interfaces not only those tests built on top of the system but also existing software packages can make use of the model’s object structure. The implemented object model is one of the cornerstones of the IDEA+ project, aiming to provide an Integrated Design Environment for Architecture.

title	Prototype of an Interactive Case Library for Architectural Design
source	Timmermans, Harry (Ed.), Fourth Design and Decision Support Systems in Architecture and Urban Planning Maastricht, the Netherlands), ISBN 90-6814-081-7, July 26-29, 1998
summary	Architects acquire an important part of their design knowledge from existing designs. Specific design projects from the past form an indispensable source of information and inspiration. Hence the idea todevelop a digital library of design cases that can be easily accessed during design. The paper describes a recently developed prototype of such a case library, intended to assist architecture students in the studio,yet with the potential of expansion into the office setting. When students enrol into a design project, they usually receive a reader with some relevant examples. At first sight, the digital case library only seems torepresent these examples into another medium, yet there are some important differences between both. Unlike the reader, the library has at its core an indexing-system which allows the easy retrieval of relevantinformation. By labelling projects with several features and making links between similar designs, the tool supports both directed search and browsing. A second difference is that the library is interactive. Studentsare not only able to consult interesting examples, but also to add other projects they consider relevant, to make links between them, to create extra indices etc. Finally, the tool allows to combine several media andto create links to external information sources.

title	Anticipation in Evaluation and Assessment of Urban and Regional Plans
source	Timmermans, Harry (Ed.), Fourth Design and Decision Support Systems in Architecture and Urban Planning Maastricht, the Netherlands), ISBN 90-6814-081-7, July 26-29, 1998
summary	In order to start a move toward better computer based supporting tools for the assessment of urban and regional plans, a new research and development endeavour is proposed. In so doing, anticipation andanticipatory computing, i.e. a technique applying modelling and simulation, is found to be an interesting and promising point of departure. Hence, a fuzzy cellular automata computer model (STF) for simulation and anticipation of geographical or physical space is constructed. The main idea is to map anurban plan onto the STF for its assessing. STF has a normalised and continuous, i.e. fuzzy, system variable while both the time and space dimensions take on discrete values. Further, while ordinary cellularautomata use local rules, global ones are employed in STF, i.e. there is a total interdependence among all the cells of the automata. Outcomes of STF can be interpreted more as possible future states than exact predictions. Preliminary results seem to be well in line with main characteristics of planned urban or regional geographical spaces. Further, for the managing of multi-criteria choice situations, a fuzzy procedure – the Ordered Weighted Average (OWA) procedure – with continuous control over the degree of ANDOR-ness and with independent control over the degree of tradeoff, is proposed.
