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	A Web-Based Virtual Reality Model for Preliminary Estimates of Hi-Rise Building Projects
source	Timmermans, Harry (Ed.), Sixth Design and Decision Support Systems in Architecture and Urban Planning - Part one: Architecture Proceedings Avegoor, the Netherlands), 2002
summary	Cost estimating of a construction project at its early stage is considered to be very important task since it will be used as a base to commit or otherwise not to commit funds to that project. Preparation of a reliableand realistic preliminary estimate to aid the decision makers to commit funds for a specific project is a complicated assignment. Traditional methods and operations produced unsatisfactory aid due to lack ofaccuracy especially in the pre-design stage of a project. This participates in the increase of percentage of bankruptcy in the construction industry, which has dramatically climbed up and ranked as 15 percent of thewhole bankruptcies claimed in Canada (Statistic Canada 1998). This paper presents a methodology for developing and a Web-based model to automate preliminary cost estimates for hi-rise buildings. This is achieved by integrating a database with design drawings in a Virtual Reality (VR) environment. The model will automatically generate preliminary estimates after modifying a 3D CAD drawing. It provides the user the option to visualize and simulate the drawing and its cost data through VR environment. Having done that, it will allow owners, architects and cost engineers to view a constructed building project, change its geometric objects and shapes, and accordingly generate a new conceptual cost estimate.

title	Conjoint Analysis and Virtual Reality - A Review
source	Timmermans (ed.), 4 Ih Design and Decision Support Systems in Architecture and Urban Planning Conference.
summary	This paper describes a review of an ongoing research project which aims to develop a conjoint analysis and virtual reality (CA&VR) system as part of a design information system in virtual reality. The research project aims to develop a design system that can be used for interactive design and evaluation of design alternatives. A virtual environment model and dynamic virtual objects representing the different design aspects of interest can present a design. The different design aspects are called attributes. Each attribute level is a different state of the concerned virtual object. In the case of a virtual walk through a building design, the system can be viewed as a visual simulation of the environment. The CA&VR system has the potential advantage that individuals' preferences can be measured in designed hypothetical choice situations. As part of the ongoing research project, principles underlying the CA&VR system will be illustrated by simple examples. The status of this research project, both in retrospect and in prospect will be described.

title	Representing Collaborative Multi- Knowledge Agents as Generic Rules
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	This paper discusses the internal representation of a multi-knowledge agent decision support system that was developed for building thermal design. The system is able to provide designers with specific problem detection in thermal design without the use of rules of thumb. The paper describes how generic rules can be used as virtual agents and how these agents can interact using a blackboard model. The generic rules utilized use logical variables as a strategy to capture generality. This allows the rules todeal with variables that can be replaced by any possible term. In addition, it allows the rules to be equivalent to the infinite set of rules that could be obtained if the variables were replaced in all possible ways by terms. In the system, these terms include the building elements and systems that affect the thermal behavior of the building. Problems associated with agent conflicts and how they were resolved in such a model are described.

title	Generating, evaluating and visualizing construction schedules with CAD tools
source	Automation in Construction 7 (6) (1998) pp. 433-447
summary	Collaborative AEC technologies centering around component-based CAD models support architectural and structural perspectives. The construction perspective is often neglected because an important dimension for construction–time–is missing. Construction planners are forced to abstract CAD model building components into schedule models representing time. 4D-CAD (3D-CAD+time) removes this abstraction by linking a 3D building model and schedule model through associative relationships. Adding time to 3D-CAD models extends the use of CAD tools from the design phase to the construction phase. Although commercial 4D tools exist that allow planners to build 4D models and create graphic simulations of the construction process, these tools lack features to support analysis of these models, easy generation and manipulation of such models, and realistic visualizations of the construction process. This paper discusses these shortcomings, highlights requirements for CAD tools to support construction planning tasks, and describes our efforts to develop 4D tools that generate 4D+x models that more realistically represent the construction process.

title	Information Ordering for decision support in building 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	A systematic approach for the application of AI-based information processing for information ordering in architectural building design is described. For this purpose fuzzy associative memory (FAM) method is considered. In this system FAM is used for knowledge representation in building design concerning the functional & technical requirements information and its graded relevance to individuals concerned in the same context. A set of FAM rules having been established as a knowledge base for use, a pattern of information in the form of a fuzzy vector is fed to each FAM rule. Here, a decision support system is aimed to convey the information to the respective individuals and/or bodies involved, in a graded form, according to their capacity of involvement in the building design. By exploiting the binary logic, each FAM rule is fired in parallel but to a different degree so that each rule generates an m-dimensional output fuzzy vector Pi. The union of these vectors creates m-dimensional fuzzy decision vector D that provides the ordered information addressed to respective individuals and/or bodies mentioned. Using simulated data, a verification procedure for the performance of the approach is investigated and by means of the work, the role that artificial intelligence in architecture and building design might play, is pointed out.

title	A Theoretical Framework for the Analysis and Derivation of Orthogonal Building Plans and Sections
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 are generally perceived as “Formgivers with an extraordinary gift” (Ackerman, 1980:12). Implicit in this statement is the belief that the operations that architects employ to compose their designs are the product of a creative faculty that is beyond the reach of rational discourse, and thereby cannot be subjected to logical investigation. This view is detrimental to the advancement of knowledge about architectural composition and adversely affects both practice and education in architecture. More specifically, it prevents the architectural community from acquiring of a more refined conception about how architects derive their designs. In contrast to this view, this study demonstrates that architectural form-making is amenable to logical analysis. In specific, this is to be done through a theoretical and computational framework that describe and explain the tasks involved in the making of orthogonal building plans and sections. In addition to illustrating the susceptibility of architectural form-making to logical analysis, the frameworks proposed in this study overcome the limitations of previously established theories thatdeal with architectural form-making. These can be divided into two categories: normative and positive theories.Normative theories include architectural treatises and manifestos. A major limitation of normativetheories is that they have limited explanatory power. Their concern is with promoting a specific aesthetic ideology and prescribing rules that can be used to derive compositions that conform to it. Therefore, they cannot be used to explain form-making in general. Positive frameworks, such asshape grammar, rely on rules to describe derivation and analysis processes. Nevertheless, they do not provide a comprehensive description of the tasks involved in architectural form-making. This causes the relation between the rules and compositional tasks to be ambiguous. It also affects adversely the ability of these frameworks to provide architects with a complete understanding of the role of compositional rules in derivation or analysis processes.

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.

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	Computational Specification of Building Requirements in theEarly Stages of 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	We have been exploring computational techniques to help building designers to specify design requirements during the early stages of design. In the past, little has been accomplished in this area either in terms of innovative computational technologies or the improvement of design performance.The prospect of improving design productivity and creating a seamless process between requirements specification and formal design are our primary motivations. This research has been conducted as partof a larger project entitled SEED (Software Environment to Support Early Phases in Building Design). SEED features an open-ended modular architecture, where each module provides support for a design activity that takes place in early design stages. Each module is supported by a database to store and retrieve information, as well as a user interface to support the interaction with designers. The module described in this paper, SEED-Pro (the architectural programming module of SEED), is a workingprototype for building design requirements specification. It can be used by other modules in SEED or by design systems in other domains, such as mechanical engineering, civil engineering, industrial designand electrical engineering. Our approach to SEED-Pro is divided into two phases: core, and support functionalities. The core functionalities operate in an interactive mode relying on a case-based approach to retrieve and adapt complex specification records to the problem at hand. The supportfunctionalities include the case-base, the data-base, and the standards processing environment for building specification tasks. Our findings indicate that SEED-Pro: (1) is a tool that structures the unstructured domain of design requirements; (2) enables the integration of design requirements with the rest of the design process, (3) leads to the creation of complex case-bases and (4) enables the observation of their performance in the context of real world design problems.

doi	https://doi.org/10.52842/conf.caadria.1998.021
summary	This paper investigates the relationship between different design approaches and their effectiveness in the formulation of design concepts. This inquiry will focus on the computer as the sole design and developmental tool. The research employs a short design programme, a small building with a given urban site, as its investigative vehicle. Nineteen second year students of the Mackintosh School of Architecture were monitored and their design progress evaluated. They were split into two groups: one used CAD and AEC as the only drawing and modelling tool, tutorial and review, and another used conventional tools of drawing and model making (mixed media). Structured interviews and personal observations were used as a means for data collection. Questionnaires were administered to students and their response was analysed using the statistical programme SPSS (Statistical Package for the Social Sciences). The Mann-Whitney test was used to test the Null Hypothesis that different design approaches will not produce different design outcomes. Correlation, Regression and the X2 test of independence were also employed to screen data and identify patterns of relationships.

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.

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 universal principle of architecture can be defined as follows: “The architectural product is the synthesis of the different man-made physical environments that are formed by locating the series of building components in different ways”. Within this context; it is necessary to determine the principle of building assembly and the assembly of ‘material components’ in order to produce the building. The material components are the elements of sub systems (such as; structural, envelope, services, partitions, circulation, and finishing systems) which form the building system of an architectural product. Every building is an integrated product. Integration defines the relations of sub systems with the whole. Therefore, it is necessary to define the sub systems and their relations in realizing the architectural product. This paper presents the analysis principles of the sub-systems, relationship between the analyzed systems and components, integration principles and possibilities of them, and the future conditions.

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.

summary	This paper outlines a research project that explores the participation in, and perception of, advanced technologies in architectural professional practice through a sociotechnical lens and presents empirical research findings from an online survey distributed to employees in five large-scale architectural practices in Sydney, Australia. This argues that while the computational design paradigm might be well accepted, understood, and documented in academic research contexts, the extent and ways that computational design thinking and methods are put-into-practice has to date been less explored. In engineering and construction, technology adoption studies since the mid 1990s have measured information technology (IT) use (Howard et al. 1998; Samuelson and Björk 2013). In architecture, research has also focused on quantifying IT use (Cichocka 2017), as well as the examination of specific practices such as building information modelling (BIM) (Cardoso Llach 2017; Herr and Fischer 2017; Son et al. 2015). With the notable exceptions of Daniel Cardoso Llach (2015; 2017) and Yanni Loukissas (2012), few scholars have explored advanced technologies in architectural practice from a sociotechnical perspective. This paper argues that a sociotechnical lens can net valuable insights into advanced technology engagement to inform pedagogical approaches in architectural education as well as strategies for continuing professional development.

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.
