summary	The experiences illustrated here are related to the new regulation of teaching architecture in Italy and these ones in particular have been concentrated on the technological aspects of teaching architecture. We can consider the evolution of the architect from the individual operator to the manager multi- disciplinary aspects of the building process ( building process manager) as a reality today. Information technology, specifically applied to bio-climatic architecture and environmental control, can be of great importance for this professional role, and for this reason it is very useful to include these topics at the beginning the teaching design process. This paper describes a particular approach to bio-climatic problems of the architectural project. An experimental course has been performed by the second year students of the "Laboratorio di Construzione dell' Architettura", at the School of Architecture of the Second University of Naples, in Aversa. Analysing old and new buildings, they used some flow charts for the evaluation and representation of energetic behaviour of buildings regarding their climatic and geographical environment. In the flow charts the decisions are represented by boxes that allow to determine "rightness index" related to: morphological characters of the site and environment, typology and particular organisation of the inside spaces, shape of building, technological solution of the building "skin". The navigation through the decision boxes is made with simple options like; "winds: protected or exposed site", "shape of building; free, close or cross plane", "presence of trees on the south,; yes or not",; it shows the students the bio-climatic quality of the building and, through numeric value assigned to each option, determines the "weight" of its climatic comfort.

title	Automatic generation of the controlling-system for a wall construction robot
source	Automation in Construction 5 (1) (1996) pp. 15-21
summary	In this article we present several important aspects of a software system control. This is designed and developed for a wall assembly robot in an European Esprit III project called ROCCO, RObot assembly system for Computer integrated COnstruction. The system consists of an off-line program for planning of complex assembly tasks and for generating robot actions. The execution is controlled through an adaptive user interface and gives the user the possibilities to switch in an on-line mode command. All the software is designed with the object-oriented concept and implemented in C + +. The wall assembly system is organized on the base of the successive generation of different types of actions, called "Mission", "Task", and "Action". They represent different levels of assembly complexities. Those different actions are organized in a tree structure. Furthermore, the software system can be connected to a CAD-robot simulation software for checking the robot assembly motions. Added to the control system, a recovery module has been implemented for all possible errors during the construction. First the OO-model of the world and of robot activities will be presented. Secondly, several aspects of the algorithm will be explained and at the end we will show the strategy used for the robot motion.

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.

title	Chaos, Databases and Fractal Dimension of Regional Architecture
source	Computerised Craftsmanship [eCAADe Conference Proceedings] Paris (France) 24-26 September 1998, pp. 267-270
doi	https://doi.org/10.52842/conf.ecaade.1998.267
summary	Modern research on chaos started in the 60's from an incredible finding that simple mathematical equations can model systems as complicated as waterfalls. In the 70's some scientists in the USA and in Europe started to find their way through the chaos. They were dealing with different spheres of science: mathematics, physics, biology, chemistry, physiology, ecology, economy. In the next 10 years? time the term 'chaos' has become generally known in science. Scientists gather in research groups according to their interests as to chaos and secondly according to their scientific specialities. (Gleick 1996) Objects that described chaos were irregular in shape, ripped. In 1975 Benoit Mandelbrot called them fractals. Fractal dimension that described fractal objects was also his invention. Fractal dimension is a way to measure quality: the degree of harshness, uneveness, irregularity of a given object. Carl Bovill (1996) showed how one can use fractal geometry in architecture and designing. This very fact made me try to use fractal geometry to deal with regional architecture. What or who is the degree of regionality of a given object to be for? A specially qualified person is able to state it nearly automatically. However, regionality is in some sense an unmeasurable feature. While dealing with data basis or checking particular projects, creation of procedures of automatic acquiring information concerning regionality is becoming a necessity.

title	Put: Language-Based Interactive Manipulation of Objects
source	IEEE Computer Graphics and Applications
summary	Describing a scene to a computer is an inherent task of computer graphics applications. Modeled scenes are typically built with direct placement techniques or specialized scripting languages. The scene description task could be greatly eased if natural language were an interactive control option. However, natural language understanding is notoriously difficult for computers. This difficulty is exacerbated in the case of computer graphics by the need for geometric output, not just "conceptual understanding" or high-level inferencing. General text-understanding techniques have not been successfully applied to scene generation. Typically, a few task-specific commands, such as "walk," are implemented as an ad-hoc collection of procedures. Our approach aims to separate the expressive power of fundamental natural concepts from the difficult task of text understanding. We are developing a 3D object placement system based on a combination of natural commands and interactive techniques. Guided by research in cognitive linguistics, we use basic spatial relationships--such as in, on, and at--and fundamental scene parameters--such as viewer location and object dimensionality--to identify regions of placement for objects in a scene. These natural commands can be used to quickly prototype a complex scene and constrain object placement.

title	Toward a procedure of computer simulation in the restoration of historical architecture
source	AVOCAAD - ADDED VALUE OF COMPUTER AIDED ARCHITECTURAL DESIGN, Nys Koenraad, Provoost Tom, Verbeke Johan, Verleye Johan (Eds.), (2001) Hogeschool voor Wetenschap en Kunst - Departement Architectuur Sint-Lucas, Campus Brussel, ISBN 80-76101-05-1
summary	In the field of architectural design, “visualization¨ generally refers to some media, communicating and representing the idea of designers, such as ordinary drafts, maps, perspectives, photos and physical models, etc. (Rahman, 1992; Susan, 2000). The main reason why we adopt visualization is that it enables us to understand clearly and to control complicated procedures (Gombrich, 1990). Secondly, the way we get design knowledge is more from the published visualized images and less from personal experiences (Evans, 1989). Thus the importance of the representation of visualization is manifested.Due to the developments of computer technology in recent years, various computer aided design system are invented and used in a great amount, such as image processing, computer graphic, computer modeling/rendering, animation, multimedia, virtual reality and collaboration, etc. (Lawson, 1995; Liu, 1996). The conventional media are greatly replaced by computer media, and the visualization is further brought into the computerized stage. The procedure of visual impact analysis and assessment (VIAA), addressed by Rahman (1992), is renewed and amended for the intervention of computer (Liu, 2000). Based on the procedures above, a great amount of applied researches are proceeded. Therefore it is evident that the computer visualization is helpful to the discussion and evaluation during the design process (Hall, 1988, 1990, 1992, 1995, 1996, 1997, 1998; Liu, 1997; Sasada, 1986, 1988, 1990, 1993, 1997, 1998). In addition to the process of architectural design, the computer visualization is also applied to the subject of construction, which is repeatedly amended and corrected by the images of computer simulation (Liu, 2000). Potier (2000) probes into the contextual research and restoration of historical architecture by the technology of computer simulation before the practical restoration is constructed. In this way he established a communicative mode among archeologists, architects via computer media.In the research of restoration and preservation of historical architecture in Taiwan, many scholars have been devoted into the studies of historical contextual criticism (Shi, 1988, 1990, 1991, 1992, 1995; Fu, 1995, 1997; Chiu, 2000). Clues that accompany the historical contextual criticism (such as oral information, writings, photographs, pictures, etc.) help to explore the construction and the procedure of restoration (Hung, 1995), and serve as an aid to the studies of the usage and durability of the materials in the restoration of historical architecture (Dasser, 1990; Wang, 1998). Many clues are lost, because historical architecture is often age-old (Hung, 1995). Under the circumstance, restoration of historical architecture can only be proceeded by restricted pictures, written data and oral information (Shi, 1989). Therefore, computer simulation is employed by scholars to simulate the condition of historical architecture with restricted information after restoration (Potier, 2000). Yet this is only the early stage of computer-aid restoration. The focus of the paper aims at exploring that whether visual simulation of computer can help to investigate the practice of restoration and the estimation and evaluation after restoration.By exploring the restoration of historical architecture (taking the Gigi Train Station destroyed by the earthquake in last September as the operating example), this study aims to establish a complete work on computer visualization, including the concept of restoration, the practice of restoration, and the estimation and evaluation of restoration.This research is to simulate the process of restoration by computer simulation based on visualized media (restricted pictures, restricted written data and restricted oral information) and the specialized experience of historical architects (Potier, 2000). During the process of practicing, communicates with craftsmen repeatedly with some simulated alternatives, and makes the result as the foundation of evaluating and adjusting the simulating process and outcome. In this way we address a suitable and complete process of computer visualization for historical architecture.The significance of this paper is that we are able to control every detail more exactly, and then prevent possible problems during the process of restoration of historical architecture.

title	Discourse Model for collaborative design
source	Computer-Aided Design, Vol. 28 (5) (1996) pp. 333-345
summary	A Discourse Model, including a structure and a process, is developed that provides software support for collaborative engineering design. The model shares characteristics of other design systems in the literature,including frames, constraints, semantic networks, and libraries of sharable design objects. It contributes a new model for conflict-aware agents, dynamic identification and dissemination of agent interest sets, avirtual workspace language, automatic detection of conflict, and a unique protocol for negotiation that ensures that interested agents have an opportunity to participate. The model is implementation independent andapplicable to many research and commercial design environments currently available. An example scenario is provided in the architecture/engineering/construction domain that illustrates collaboration during theconceptual design of a fire station.

title	Managing Integrity in Design Information Flows
source	Computer Aided Design (May, 1996). 28:6n, pp. 551-565
summary	The purpose of this work is to develop automatic methods of semantic integrity maintenance, in support of concurrent engineering. Semantic integrity relations in any final engineering design are built up incrementally, through the use of different computer applications. Here, the structure of these integrity relations are formalized for representation within a database. When changes to a design have to be made, they can invalidate integrity relations in other parts of the design. Formal methods are defined for identifying what data and integrity relations are invalidated by any change. Methods for making changes that minimize re-design are described and formalized. Opportunities for using semantic integrity to assess progress on a design are reviewed.

title	Integration of Cost Planning in the Architectural Design of Housing - "CP/CAD Model"
source	Application of the Performance Concept in Building (Ed: R Becker), vol 1, 2: 105-114
summary	Cost estimation in the initial phases of a project is of great interest to the construction industry. This paper proposes a new way of the integration of an architectural project and its cost estimate so as to optimise the design solutions, according to technical and economic criteria. This work explores the capacity of an elemental cost estimation method for residential buildings, when integrated with Computer Aided Design systems, to increase cost estimate precision during the early stages of design. A Cost Planning and CAD model (CP/CAD) is developed by the integration of a database and a CAD system which provides for the automatic exchange of information relative to the geometric layout of the building, the construction element build-up and the construction costs of the same. Finally the CP/CAD model is tested through the estimation of costs for some theoretical cases and also for a group of one-family houses with similar architectural characteristics. The results show the increased precision and the advantages of the model for cost estimation in the early design stages.

title	The Development of a Virtual Studio Environment to Support Collaborative Building Design
source	Design, Synergy, Collaboration - selected papers from DEcon Conference
summary	This paper describes the development of a virtual studio environment to support collaborative working in the domain of building design. By applying and extending the real-world design studio model within the Internet-based distributed computing environments, the virtual studio concept has been refined as computerised settings, which integrate both the dispersed human designers and the distributed CAD applications. The hope is to achieve the similar effect as physical co-presence while providing extra advantages such as the support for automatic communication archiving and being less obtrusive than sharing a physical office. Like its real-world counterpart (which usually consists of the office, desks, file cabinets, instruments etc), such a virtual studio consists of the several major components, including a multi-user graphical user interface displaying the shared virtual workspace on each designer's workstation, distributed multimedia databases and CAD tools for processing the domain tasks, and rich human-human interaction facilities supporting a variety of communication modes. Advance distributed object computing technologies (0MG CORBA in particular) have been adopted for modelling and implementing the distributed systems, W3 (world-wide-web) technologies have also been exploited for constructing the distributed multi-media databases and an image communication kit. In contrast to the traditional CAD integration which is usually focused solely on the well-structured technical part of the product and process, the described research advocates a human-centred systems development strategy in which design is first of all taken as a process of social construction.

title	An optimization method of the facility location by genetic algorithm
source	Timmermans, Harry (Ed.), Third Design and Decision Support Systems in Architecture and Urban Planning - Part two: Urban Planning Proceedings (Spa, Belgium), August 18-21, 1996
summary	In planning of community-facilities, it is important to decide the facility location to provide the effective service for residents. The behavior of residents using the facility and the evaluation methods of the location have been studied. But, finding the optimum location is very hard in actual planning because the volume of calculation depends on the number of feasible locating points of facilities. To conquer the difficulty of searching the optimum location, we propose an optimization method using Genetic Algorithm. An alternative of location is expressed by a chromosome. Each chromosome consists of genes, and each gene expresses a located zone of the facility. We gave definitions of genetic procedures; crossing-over, mutation and selection. Alternatives of the facility location are generated by these genetic procedures like as life evolution. For each alternative, the behaviors of users are estimated by a spatial-interaction model, and the facilities that residents in each place choose are determined. The effectiveness of the location is measured by a total sum of distances between the facility and the user. After the confirmation of the effectiveness of our method by applying on ideal example problems, we applied it on the actual problem in Japanese town. By this method we could find the optimum location in about one-third time and effort as compared with the ordinal method.

doi	https://doi.org/10.52842/conf.ecaade.1996.059
summary	In the paper presented in the last ECAADE conference in Palermo we described a first hypertext for the analysis of ancient buildings. One section of the hypertext was devoted to show diagnostic procedures and specific instrumental tests for building rehabilitation. We can consider that the hypertext represent the best answer to the request of an organised knowledge coming from students of the schools of architecture and public operators. So we describe how the proposed arrangement of the diagnostic tests can become a real operative tool technicians of public agencies and powerful means of building technology knowledge for students too. The diagnostic procedures are related to the specific needs of the architectural design; changing ways to archive the tests are showed. The goal is to allow the architects, operating in the rehabilitation field, to operate the right choice of diagnostic methods to avoid doing many unnecessary, expensive tests.

title	Modeling Designs with Shape Algebras and Formal Logic
source	University of California
summary	A formal, hierarchical model of shape, spatial relations and non-spatial properties is presented, constructed from first principles of geometry, topology and logic. The combination of the two major paradigms used here, shape algebras and logic, is one which has been largely unexplored. The underlying interest is the development of generalized design modeling systems in which the components may be used for a variety of synthesis and recognition problems. The algebras of shape described by Stiny have been shown to be useful in the generation and analysis of designs. The generality of their representations, their non-reliance upon predetermined structure, and their use in combination provide a richness of expression lacking in more traditional representations. The use of formal logic as a specification tool for modeling spatial relations is investigated here. Logic has proven itself useful as a programming and specification tool, providing advantages over traditional procedural programming methods. Among those is the ability to specify the knowledge to be encapsulated in a model without the need to specify data manipulation procedures. It is argued that specification in logic provides a natural method of development. The model is developed by extending the formalisms of shape algebras with the use of logic to make more precise, generalized, parametric definitions of shape and spatial relations than has been previously possible. The value of such a model is demonstrated by the use of these generalized spatial relations for solving typical problems in the fields of geographic information systems and architecture. The advantages of the representations used over more traditional 'kit-of-parts' models is also illustrated.

summary	We are in the act of forming the Technology & Electronics society: a society which cultural, psychological, social and economical facets take shape according to the development of technology and electronics, specially in the fields of computer and information. The influence of these mighty functions, produced by the bit, is prevalent in all the science and social courses; in fact, it has already invaded the artistic world. It did not take long after the birth of the computer for it to become the new tool for artistic production; it revolutionized the traditional production habits, production procedures, methods of expression and the work place in artistic creativity, thus bringing the tides of change in the artistic context and attitude towards the study of the Arts.

title	Computer-Mediated Cooperative Spatial Planning
source	Timmermans, Harry (Ed.), Third Design and Decision Support Systems in Architecture and Urban Planning - Part two: Urban Planning Proceedings (Spa, Belgium), August 18-21, 1996
summary	Decision making on spatial planning problems has to integrate recent advancements on geographical information systems with a framework that supports fair, rational and efficient decision making procedures. Such a framework will assist government and businesses with the retrieval, use and reuse of information in cooperative, distributed planning procedures requiring access to spatial data. This paper gives an overview of a computer-mediated group decision support system for the World Wide Web, namely ZENO. The target is to provide intelligent assistance to human mediators and other kinds cf "trusted third parties" during the above procedures. The role of the system is to remain neutral and help assure that the interests and goals of all members of a group, regardless of their status, are respected and appreciated. In this paper, the system's features are illustrated with a retrospective model of a real urban planning example, concerning the allocation of a new technology park in the area of the city of Bonn, where more than eighty communities, local and federal authorities, and other organizations have been requested to submit their suggestions, objections and comments on a spatial planning problem.

source	Timmermans, Harry (Ed.), Third Design and Decision Support Systems in Architecture and Urban Planning - Part two: Urban Planning Proceedings (Spa, Belgium), August 18-21, 1996
summary	The paper describes a method that has been developed to be used in a process for a systematic search of alternative designs for a network configuration. In the design process we will take into account that we may not be able to implement the full configuration all at once. Logical partial configurations must be derived. The process can than also be used to investigate the expansion of (railroad) networks. The basic idea is that either the most profitable trajectories or the trajectories that contribute most to the improved quality of the configuration will be developed first. A method cannot incorporate all criteria that are relevant for the final decision simultaneously, one of the reasons being that not all criteria are suitable for a mathematical formulation. Therefore a method cannot be used to replace current legal and political procedures. However it can be considered to be part of a decision support system that could be used in a preliminary investigation preceeding such procedures. In the example presented in this paper the criteria and calculations are kept simple for illustrative purposes. However they can easily be made more complex and realistic without damaging the fundamental concepts of the search algorithm. If the system is implemented in a way that the criteria to be used in the selection process can be chosen in interaction with the decision maker (or moderator) one can truly speak of a decision support system for the project formulation phase for the construction of the physical network. In the algorithm the network is represented as a graph and the nodes connected by the network are termed centers of attraction, supply and demand.

title	Integrating Shadow Casting Methodology and Thermal Simulation
source	Proceedings of the Solar ‘96 Conference. Asheville, North Carolina: American Solar Energy Society, 1996, pp. 271-276
summary	This paper describes an experiment that integrates shadow casting methodology and thermal simulation algorithms developed by the authors. The 3D shadow procedures use a polyhedral representation of solids within a Cartesian space that allows for accurate casting of shadows. The algorithm is also capable of calculating surface areas of polygonal shadows of any arbitrary shape and size. The thermal simulation algorithms – using the Transfer Function Method (TFM) – incorporate the shaded area calculations to better predict solar heat gain from glazing based on transmitted, absorbed, and conducted cooling loads. The paper describes the use of a 3D computer model to illustrate the impact of the pattern and area of shading on the visual and thermal properties of building apertures. The paper discusses the objectives of this experiment, the algorithms used, and their integration. Conclusions and findings are drawn.

title	On the Development of 3-D Schematic Design System Utilities for Planning Sketches and 3-D Modeling
source	CAADRIA ‘96 [Proceedings of The First Conference on Computer Aided Architectural Design Research in Asia / ISBN 9627-75-703-9] Hong Kong (Hong Kong) 25-27 April 1996, pp. 63-73

summary	Though it is the basic tasks of designers in a schematic design stage both to program design requirements and, then, to develop spatial images of a building following those programs, most CAD systems have lacked convenient utilities to interpret a program for some forms of spatial designs, or to assess developed designs referring to the prepared programs. This paper, in the first part, reviews design procedures of designers and the internal limits of the existing CAD system, and in the second part, discusses a schematic design system that the authors have developed. Presenting the case study with the system, the authors show that the system provides a convenient environment of schematic design.
