title	A Decision Support System for Local Authorities in Malaysia
source	Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary	Given the dynamic nature of urban development, if is particularly important to have a well conceived planning management activity which can serve as the eyes and ears of a large planning process, up-to-date and reliable. It provides monitoring and the surveillance of compliance with planning regulations and it serves as an easy warning system with regard to sources of shortfalls in the process of urban planning. Information is therefore needed at the local authority level to facilitate administrative procedures, policy planning and plan implementation. Also, the advent of corporate planning and the continued squeeze on local authority expenditure require local authorities to examine critically whether rational decisions are made. Against this background, this paper examines the functions of a local authority particularly in the context of planning and urban management. These and the types of data which support them provide the fundamental framework upon which a model of geographic data entities and their relationship is developed. Ultimately, it will be reasonable to assume that a local authority will have developed a GIS providing a complete local authority coverage of up-to-date and accurate information at the parcel base. Consequently, it will be used to assist planning decisions taking into account among other things, the current scenario of the proposed development, physical constraints and future impacts. Further, a customized menu driven user interface is developed to allow planners and decision makers to view and analyze the planning scenarios interactively before deciding on the final plan. The paper concludes with a discussion on problems encountered in the project namely data availability and organizational issues.

title	Hypermedia-aided GIS in Urban Planning
source	Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary	Town planning in Denmark is undergoing major changes from a planning approach focusing on regulation and individual frameworks for town districts, to a planning approach emphasizing the urban characteristics and drawing overall guidelines for planning. At the same time, attention has shifted to urban renewal and urban remodelling. This means that more qualitative data are needed.These new data types such as digital film, are to form part of a future GIS for the town. The digital film will change the impression of what data can profitably be used in a GIS. Even animations and 3D models, which were previously processed with considerable data power can beplayed as digital films. In the course of the next few years, the most ordinary applications will be able to play digital films and together with the progress made in other media, a development towards hypermedia will be a possibility. The paper will give some examples of how this integration may be carried out. In continuation of the preparation of a municipality atlas and in connection with an EC-subsidized urban renewal project, the municipality of Aalborg has chosen to work outa digital catalog which will in time replace the present local planning regulations.

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	Creating a Data Base for Parking System in Cities - Malaysia
source	Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary	Transport, one of the major urban systems somehow give rise to a varying degree of problems in many different cities. Malaysia being among the developing nations is no exception to such problems. When urban development takes place, infrastructure has to be provided adequately. The needs of an efficient parking system have to be at par with the development itself. Parking for example plays a similar role and it is indeed vital for every motorists. This paper outlines the general problems related to parking in urban areas and a generalised software suitable for micro-computer system is developed. The rationale is to help local authorities improve financial management besides assisting them in physical planning and other aspects ofdecision making.

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	GIS: Science or Tool - The Built Environment Perspective
source	Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary	This paper attempts to locate GIS in the context of the built environment professions, rather than in the context of computer science, recognizing the integrated but limiting approach of viewingGIS from a strictly computer / spatial science perspective. The paper reviews the conflicts and tensions appearing in the GIS debate seeing them as reflecting the differences between the perceptions and interests of software developers and those of the professions. The "spatial science versus professional tool" dilemma is therefore critically assessed. Science is identified as the dominant paradigm within which GIS development has taken place. This encompasses the emphasis on GIS as spatial science; the interest in particular forms of spatial analysis; a narrow approach to the idea of information; the debate about the appropriate emphasis on the location for GIS in undergraduate education. The interests and activities of the professions cannot be encompassed within the pre-existing science paradigm. The paper identifies the interest the professions have had in broad geographical issues (as distinct from narrow spatial issues). It recognizes the different conventions and procedures used in recording and using geographical information, not all of them objective or scientific. It views the computer, not as a "scientific engine", but as a modern medium for representing and analyzing information. This includes storage and analysis, both internally (algorithmic manipulation) and outside (qualitative manipulation, beyond formal -"computer"- logic). This approach suggests a framework for research of a nature more sympathetic to the needs of the built environment professions in particular and an agenda which would include an examination of: (i) the conventions and procedures used in the professions to collect, store and process information and how these translate to computer technology; (ii) the types of software used and the way procedures may be accommodated by combining and integrating packages; (iii) the dynamism of GIS development (terms such as "dedicated", "mainframe", "PC-based", "distributed", "pseudo-", etc. are identified as indicativeof the need for professions-based approaches to GIS development); (iv) a critique of "information" (modelling of information flows within the professions, may yield valuable insights into the (modelling of information flows within the professions , may yield valuable insights into the similarity of requirements for a variety of "workplace scenarios").

title	Integration System for Urban Design from Planning Management to Visalization
source	Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary	Advanced tools based on CAD or GIS systems and simulation methods have recently been introduced to support the many aspects of urban planning (design, analysis, evaluation, presentation). This research aims at constructing a system by integrating these support tools and linking GIS and simulation tools. The major purpose of this system are to manage the geographical data base of the target urban area, utilize the digital information of the area for planning and analysis,evaluate the impact of alternative proposals on the physical environment such as sunlight and daylight, visualize the results of analysis, and support the management of urban redevelopment /development projects. This paper shows some applications to illustrate usefulness of the system. These examples are concerned with a contemporary problem in urban planning of Tokyo: redevelopment of low-rise high-density residential districts and high-rise development in the central business districts. Urban redevelopment for the high-density urban areas in Japan requiresa evaluation of alternative plans by visualizing their environmental impact. This system enables the quantitative analysis of the environmental impact by using 3-dimensional geographical data andsimulation methods. In general, the merit and effect of planning support systems are recognized in terms of the "efficiency" of the planning process. The primary function of GIS is thought to bethe unification and management of various pieces of information. In addition, this research indicates the effectiveness of the integrated system in terms of utilizing the geographical information and visualizing the image of the future environment.

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.

title	Urban Gis - The Application of the Information Technologies to Urban Management
source	Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary	Many cities in the UK and indeed throughout the developed world are characterised by the all too familiar symptoms of urban blight caused by insensitive intervention in the environment. The common denominator within this class of problem is the lack of a coordinated, integrated approach to the planning, design and maintenance of our cities. The cycle of development and redevelopment calls for input from a diverse range of disciplines relating to architecture, civilengineering, transport engineering, and the management of city utilities. This lack of a common up datable information base renders access to a global view of the city difficult, if not impossible.This problem has provided the motivation to move towards an integrated philosophy regarding information collection, collation and dissemination. The impetus is provided primarily through theincreasing complexity of urban management but also through central governments policy to progress towards decentralisation of services. Fiscal pressure to increase efficiency, lower manpower resources and arrive at speedier judgements all point to an increasing reliance on the information technologies. Current work at ABACUS within Strathclyde University addresses research whose objective is to identify, and then prototype, a relevant urban information system. It is proposed that by attributing a geometrical framework with those physical quantities thatare relevant to the formal and functional evaluation of the urban environment, the means of evaluating the qualities and quantities of the buildings aswell as the social and economic prospects may be realised.

title	Identification And Analysis of the Recreational Behaviour Forms and the Needed Recreational Space Using the Integrated Spatial and Object-Oriented Gis: Concepts and Statements
source	Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary	This paper is concerned with how to measure and investigate changes in the recreational behaviour and the required recreational space in Polish seaside recreational areas in last few years. Spatial information is an integral part of the identification and analysis of recreational behaviour and required recreational space. We postulate, therefore, that spatial information should be fully incorporated in integrated object-oriented GIS and Decision Support Technology. We argue in this paper that the existing theoretical approaches with their descriptive and technical basis do not offer directions for its application and evaluation. They do not seek to explain the processes undergone by spatial information, nor define appropriate data models. New approaches to GIS use object-oriented structures and expert systems concepts, and they will become increasingly helpful in understanding GIS. It is not unreasonable to expect that the most important issue is to use a data model or object-oriented models which closely represent the user's concept of the geographic object for representing spatial phenomena. We have discovered that most Polish users in this field are unable to collect the data they require directly. Thus they have to use methods and techniques, which cannot be found in GIS such as SWOT analysis. According to our experiences, the identification and analysis of the recreational behaviour and the required recreational space should be defined as a system approach where: (i) recreational space requires an object, (ii) state of recreational space is defined by the set of values of recreational space features, and (iii) the utility of the recreational space is defined by a set of features. The identification and analysis of the recreational behaviour in the presented approach are based on the features/utilities matrix of the recreational space and the computer map. The development of such a system needs many organizational changes. It is shown that in many applications organizational rather than the technical aspects of GIS determine their future and open the way to new spatial analytical techniques.

title	Implementing an Integrated Environment for Urban Simulation CAD, Visualization and GIS
source	Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary	Using technology which has been adapted from military flight simulation hardware and software, researchers at UCLA's Graduate School of Architecture and Urban Planning are currently developing an integrated computing environment for Urban Simulation which includes a high-level visual simulation package, an industry standard CAD system, and a traditional two dimensional geographic information system and data bases. The focal point of the integrated system is a visual simulation engine which has been developed using Silicon Graphics' IRIS Performer application development environment. With this system, aerial photographs can be combined with street level video to efficiently create a realistic (down to plants, street signs and the graffiti on the walls) model of an urban neighbourhood which can then be used for interactive fly and walk-through demonstrations. Links have been established between this visual simulation system and AutoCAD to allow models (at varying levels of detail) to be generated using the CAD system and translated into the form required for the visualization system. Links between the GIS system (in this case ARC/INFO and ARCVIEW) and the visual simulation system provide the capability for dynamic query and display of information from the GIS data base in a real-time 3-dimensional format. Links between the CAD and GIS systems allow common base maps to be used for the GIS and modelling systems as well as automatic generation of 3-d form. While an earlier paper by the authors discussed proposed strategies for such an Urban Simulation System, this paper focuses on the results of actual implementation of these strategies, as well as the use of the system for modelling, exploration and display of alternative physical environments.

title	Resource Based Approach to Generalization in the Context of GIS
source	Linkoping, Suécia: Department of Computer and Information Science, Linkoping University
summary	A reactive planning system for decision support in the context of GIS will be a complex system. The information flow is often great but of varying quality. Resources should be used as knowledge structures to organize the data involved in such systems and generalizations to reduce the data volume and create overviews. This paper discusses what is meant by resources in the context of GIS and planning and how generalizations can be used in a wider perspective than only for cartographic simplification. The project, which is in an early state, has the goal to design the data structures for a decision support system for crisis and emergency management.

title	Environment – Urban Interface within Urban Growth
source	Van Leeuwen, J.P. and H.J.P. Timmermans (eds.) Developments in Design & Decision Support Systems in Architecture and Urban Planning, Eindhoven: Eindhoven University of Technology, ISBN 90-6814-155-4, p. 49-62
summary	This work presents the synthesis of a model of urban growth dedicated to accomplish simulations of urban spatial dynamics, based on integrated urban and environmental factors and promoting simultaneity among external and internal growth. The city and surrounding environment are captured and modeled in computational ambient, by application of the centrality / potential model (Krafta, 1994 and 1999), with support of graph theory, cellular automata, GIS and geocomputation. The model assumes the city as a field of opportunities for obtaining income, mediated by the space, which is composed of urban and environmental attributes, that work as attractors or as resistances for the urban growth. The space configuration and the distribution of those attributes generate tensions that differentiate qualitatively and quantitatively the space, through the centrality measure (built with the support of graphs techniques), coming to provoke growth in places with larger potential of development (built with the help of techniques of CA – cellular automata). Growths above environmental thresholds are considered problems, generated and overcome in the same process of production of the urban space. Iterations of that process offer a dynamic behaviour to the model, allowing to observe the growth process along the time. The model presents several possibilities: a) urban - natural environment integration; b) internal and external growth integration; c) variety in the scale; d) GIS integration and geocomputation; e) user interface; f) calibration; g) theoretical possibilities; and h) practical possibilities.

title	Design Tools in an Integrated Cad-Gis Environment: Space Syntax asan Example
source	Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary	The focus of this paper is how to make good use of the possibilities offered by integrated CAD-GIS software. It addresses the problem of the difference in types of information required by urban designers and urban planners to perform their tasks. It is stated that there is an overlap in these types of information. Both planners and designers can benefit from the extension of information offered to them by the other party. Integrated CAD-GIS software facilitates the exchange of information. There is a need for implementation in the integrated CAD-GIS environment of a type of information that addresses designers and planners alike. The paper takes Space Syntax models as an example of such information.

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	Parking Simulation with a Geographical Information System: A Basic Framework
source	Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary	Nowadays, parking is one of the most important elements of urban transportation and environ-mental planning. It is important to integrate parking planning with for example urban transporta-tion and environmental planning. To do this, a tool in which all these planning activities can be brought together, is essential. A Geographical Information System (GIS) might offer opportunities to combine such activities. It offers possibilities to manipulate, analyze and present data from different kind of databases, and ties different databases directly to some spatial entities. This paper describes a framework for parking simulation, the needs to conduct such a simulation, the tools a GIS offers for this and a hypothetical case to show how a parking simulation modelling can be integrated with G1S-technology.

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	SHARED SPACE’ AND ‘PUBLIC SPACE’ DIALECTICS IN COLLABORATIVE ARCHITECTURAL DESIGN.
source	Proceedings of Collaborative Decision-Support Systems Focus Symposium, 30th July, 2002; under the auspices of InterSymp-2002, 14° International Conference on Systems Research, Informatics and Cybernetics, 2002, Baden-Baden, pg. 27-44.
summary	The present paper describes on-going research on Collaborative Design. The proposed model, the resulting system and its implementation refer mainly to architectural and building design in the modes and forms in which it is carried on in advanced design firms. The model may actually be used effectively also in other environments. The research simultaneously pursues an integrated model of the: a) structure of the networked architectural design process (operators, activities, phases and resources); b) required knowledge (distributed and functional to the operators and the process phases). The article focuses on the first aspect of the model: the relationship that exists among the various ‘actors’ in the design process (according to the STEP-ISO definition, Wix, 1997) during the various stages of its development (McKinney and Fischer, 1998). In Collaborative Design support systems this aspect touches on a number of different problems: database structure, homogeneity of the knowledge bases, the creation of knowledge bases (Galle, 1995), the representation of the IT datum (Carrara et al., 1994; Pohl and Myers, 1994; Papamichael et al., 1996; Rosenmann and Gero, 1996; Eastman et al., 1997; Eastman, 1998; Kim, et al., 1997; Kavakli, 2001). Decision-making support and the relationship between ‘private’ design space (involving the decisions of the individual design team) and the ‘shared’ design space (involving the decisions of all the design teams, Zang and Norman, 1994) are the specific topic of the present article. Decisions taken in the ‘private design space’ of the design team or ‘actor’ are closely related to the type of support that can be provided by a Collaborative Design system: automatic checks performed by activating procedures and methods, reporting of 'local' conflicts, methods and knowledge for the resolution of ‘local’ conflicts, creation of new IT objects/ building components, who the objects must refer to (the ‘owner’), 'situated' aspects (Gero and Reffat, 2001) of the IT objects/building components. Decisions taken in the ‘shared design space’ involve aspects that are typical of networked design and that are partially present in the ‘private’ design space. Cross-checking, reporting of ‘global’ conflicts to all those concerned, even those who are unaware they are concerned, methods for their resolution, the modification of data structure and interface according to the actors interacting with it and the design phase, the definition of a 'dominus' for every IT object (i.e. the decision-maker, according to the design phase and the creation of the object). All this is made possible both by the model for representing the building (Carrara and Fioravanti, 2001), and by the type of IT representation of the individual building components, using the methods and techniques of Knowledge Engineering through a structured set of Knowledge Bases, Inference Engines and Databases. The aim is to develop suitable tools for supporting integrated Process/Product design activity by means of a effective and innovative representation of building entities (technical components, constraints, methods) in order to manage and resolve conflicts generated during the design activity.

The model may actually be used effectively also in other environments. The research simultaneously pursues an integrated model of the: a) structure of the networked architectural design process (operators, activities, phases and resources); b) required knowledge (distributed and functional to the operators and the process phases). The article focuses on the first aspect of the model: the relationship that exists among the various ‘actors’ in the design process (according to the STEP-ISO definition, Wix, 1997) during the various stages of its development (McKinney and Fischer, 1998). In Collaborative Design support systems this aspect touches on a number of different problems: database structure, homogeneity of the knowledge bases, the creation of knowledge bases (Galle, 1995), the representation of the IT datum (Carrara et al., 1994; Pohl and Myers, 1994; Papamichael et al., 1996; Rosenmann and Gero, 1996; Eastman et al., 1997; Eastman, 1998; Kim, et al., 1997; Kavakli, 2001). Decision-making support and the relationship between ‘private’ design space (involving the decisions of the individual design team) and the ‘shared’ design space (involving the decisions of all the design teams, Zang and Norman, 1994) are the specific topic of the present article. Decisions taken in the ‘private design space’ of the design team or ‘actor’ are closely related to the type of support that can be provided by a Collaborative Design system: automatic checks performed by activating procedures and methods, reporting of 'local' conflicts, methods and knowledge for the resolution of ‘local’ conflicts, creation of new IT objects/ building components, who the objects must refer to (the ‘owner’), 'situated' aspects (Gero and Reffat, 2001) of the IT objects/building components. Decisions taken in the ‘shared design space’ involve aspects that are typical of networked design and that are partially present in the ‘private’ design space. Cross-checking, reporting of ‘global’ conflicts to all those concerned, even those who are unaware they are concerned, methods for their resolution, the modification of data structure and interface according to the actors interacting with it and the design phase, the definition of a 'dominus' for every IT object (i.e. the decision-maker, according to the design phase and the creation of the object). All this is made possible both by the model for representing the building (Carrara and Fioravanti, 2001), and by the type of IT representation of the individual building components, using the methods and techniques of Knowledge Engineering through a structured set of Knowledge Bases, Inference Engines and Databases. The aim is to develop suitable tools for supporting integrated Process/Product design activity by means of a effective and innovative representation of building entities (technical components, constraints, methods) in order to manage and resolve conflicts generated during the design activity.

summary	The paper describes a preliminary design model for air-conditioning systems (ACS). Using a commercially available drafting tool (AutoCAD) and an ACS design program (HevaSketch) the model attempts to develop a comprehensive solution at an early phase of ACS design. Contextual knowledge (in the form of local building codes and equipment) is made available to the designer through a linked database. output from the model is in the the form of 2D and 3D drawings, parts and material schedules and detailed design calculations.
