title	THE FULL-SCALE MODEL WORKSHOP
source	Proceedings of the 3rd European Full-Scale Modelling Conference / ISBN 91-7740044-5 / Lund (Sweden) 13-16 September 1990, pp. 10-11
summary	The workshop is an institution, available for use by the public and established at the Laboratory of Housing in the Art Academy's school of Architecture for a 3 year trial period beginning April 1985. This resumé contains brief descriptions of a variety of representative model projects and an overview of all projects carried out so far, including the pilot projects from 1983 and planned projects to and including January 1987. The Full Scale Model Workshop builds full size models of buildings, rooms and parts of buildings. The purpose of the Full Scale Model Workshop is to promote communication among building's users. The workshop is a tool in an attempt to build bridges between theory and practice in research, experimentation and communication of research results. New ideas and experiments of various sorts can be tried out cheaply, quickly and efficiently through the building of full scale models. Changes can be done on the spot as a planned part of the project and on the basis of ideas and experiments achieved through the model work itself. Buildings and their space can thus be communicated directly to all involved persons, regardless of technical background or training in evaluation of building projects.

title	Vector Field Representation for the Evaluation of Multiple Performance Variables
source	1990. 6, [7] p., [3] p. of ill. includes bibliography
summary	A vector field representation is proposed to simulate the spatial distribution of four building system performance variables: light, sound, radiant heat, and air flow. From this simulation, a measure of the impact of adding, deleting, or modifying an object in the field is computed. This measure serves as a passive evaluation of the user/designer's decision to modify the location or dimensions of the object in a space. This process of simulation-evaluation is performed by a performance module (PM), which is viewed as a component of a CAAD System (Computer Architectural Aided Design). This paper describes the motivation, objectives, methodology and preliminary results of the approach

title	SEED: A Software Environment to Support the Early Phases in Building Design
source	Proceeding of IKM '94, Weimar, Germany, pp. 5-10
summary	The SEED project intends to develop a software environment that supports the early phases in building design (Flemming et al., 1993). The goal is to provide support, in principle, for the preliminary design of buildings in all aspects that can gain from computer support. This includes using the computer not only for analysis and evaluation, but also more actively for the generation of designs, or more accurately, for the rapid generation of design representations. A major motivation for the development of SEED is to bring the results of two multi-generational research efforts focusing on `generative' design systems closer to practice: 1. LOOS/ABLOOS, a generative system for the synthesis of layouts of rectangles (Flemming et al., 1988; Flemming, 1989; Coyne and Flemming, 1990; Coyne, 1991); 2. GENESIS, a rule-based system that supports the generation of assemblies of 3-dimensional solids (Heisserman, 1991; Heisserman and Woodbury, 1993). The rapid generation of design representations can take advantage of special opportunities when it deals with a recurring building type, that is, a building type dealt with frequently by the users of the system. Design firms - from housing manufacturers to government agencies - accumulate considerable experience with recurring building types. But current CAD systems capture this experience and support its reuse only marginally. SEED intends to provide systematic support for the storing and retrieval of past solutions and their adaptation to similar problem situations. This motivation aligns aspects of SEED closely with current work in Artificial Intelligence that focuses on case-based design (see, for example, Kolodner, 1991; Domeshek and Kolodner, 1992; Hua et al., 1992).

title	Design Problems and Evaluative Strategies Using CAAD
source	February, 1990. 16 p. : col. ill. includes bibliography
summary	The way architects design comes into sharp focus when developing strategies for evaluating buildings. Architectural design is a highly subjective activity on the one hand but on the other it is also highly objective. The paper examines the use of CAAD systems for objective evaluation while also recognizing that this kind of evaluation has to be related to the subjective aspects of the design. In order to examine this, further research has been carried out into the use of CAAD systems to evaluate sunshading characteristics in a building design problem. The approach utilized the Integraph AMOD software to generate three dimensional models of the design proposal which were then tested using the Integraph Model View software which has a sunshading facility. The utility of this approach was tested first against criteria of how accurate the computer was in giving meaningful feedback to the designer. Secondly, how productive this approach was in the design process as compared to traditional techniques using instruments such as the heliodon. Finally, a discussion of the developments of the approach is given

title	A Computational Tool for Evaluation of Seismic Performance of RC Buildings
source	February, 1990. [1] 15 p. : ill. graphs, tables. includes bibliography: p. 10-11
summary	Recent events have demonstrated the damaging power of earthquakes on structural assemblages resulting in immense loss of life and property (Mexico City, 1985; Armenia, 1988; San Francisco, 1989). While the present state-of-the-art in inelastic seismic response analysis of structures is capable of estimating response quantities in terms of deformations, stresses, etc., it has not established a physical qualification of these end-results into measures of damage sustained by the structure wherein system vulnerability is ascertained in terms of serviceability, repairability, and/or collapse. An enhanced computational tool is presented in this paper for evaluation of reinforced concrete structures (such as buildings and bridges) subjected to seismic loading. The program performs a series of tasks to enable a complete evaluation of the structural system: (a) elastic collapse- mode analysis to determine the base shear capacity of the system; (b) step-by-step time history analysis using a macromodel approach in which the inelastic behavior of RC structural components is incorporated; (c) reduction of the response quantities to damage indices so that a physical interpretation of the response is possible. The program is built around two graphical interfaces: one for preprocessing of structural and loading data; and the other for visualization of structural damage following the seismic analysis. This program can serve as an invaluable tool in estimating the seismic performance of existing RC buildings and for designing new structures within acceptable levels of damage

source	Proceedings of the 3rd European Full-Scale Modelling Conference / ISBN 91-7740044-5 / Lund (Sweden) 13-16 September 1990, pp. 34-37
summary	By full-scale experiments we are studying functional dimensions and spatial requirements in the planning laboratory. That means, that by working in a place where the spatial dimensions could be altered and the consequences studied, we make trials to arrive at acceptable dimensions. Test subjects and various experimental set-ups enable us to study building function requirements in what we think, a quite fruitful way.

title	Modeling Objects and Environments
source	xix, 402 p. : ill. New York: Wiley, 1989. includes a short bibliography and index. Part of the Principles of Computer Aided Design series. --- See also review by Patricia G
summary	McIntosh, in ACADIA Newsletter Vol. 9 No. 3 pp 20-23, June 1990. This book introduces the concept of modeling objects in the computer's memory so it can be used to aide the process of their design. Modeling is defined as an hierarchical abstraction of data and operators to manipulate it, subject to semantic integrity constraints that guarantee the realizability of the designed artifact in the real world. Starting with general concepts of modeling, the book moves on to discuss the modeling of shapes (form) in two and in three dimensions. The discussion covers both topology and geometry. Next the book introduces the concept of shape transformations (translation, scaling, rotation, etc.), both in absolute and in relative terms. The book then introduces the concept of assembly modeling, and adds non-graphical attributes to the representation. It concludes with a discussion on user interface and parametrization. The book includes many examples written in Pascal that complement the theory, and can be used as a basis for building a geometric modeling engine. It also includes exercises, so it can be used as a text book for a two-semester advance course in geometric modeling

title	Supporting Reflection-in-Action in the Janus Design Environment
source	The Electronic Design Studio: Architectural Knowledge and Media in the Computer Era [CAAD Futures ‘89 Conference Proceedings / ISBN 0-262-13254-0] Cambridge (Massachusetts / USA), 1989, pp. 247-259
summary	We have developed a computer-based design aid called Janus, which is based on a model of computer-supported design that we think has significance for the future of architectural education. Janus utilizes a knowledge-based approach to link a graphic construction system to hypertext. This allows the computer to make useful comments on the solutions that students construct in a CAD-like environment. These comments contain information intended to make students think more carefully about what they are doing while they are doing it. In other words, Janus promotes what Donald Schon has called "reflection-inaction" (Schon, 1983). The Janus design environment is named for the Roman god with a pair of faces looking in opposite directions. In our case the faces correspond to complementary design activities we call construction and argumentation. Construction is the activity of graphically creating the form of the solution e.g., a building. Traditionally this has been done with tracing paper, pencils, and pens. Argumentation is the activity of reasoning about the problem and its solution. This includes such things as considering what to do next, what alternative courses of action are available, and which course of action to choose. Argumentation is mostly verbal but partly graphical.

title	The Use of Video-Computer Presentation Techniques to Aid in Communication Between Architect and Client
source	From Research to Practice [ACADIA Conference Proceedings] Big Sky (Montana - USA) 4-6 October 1990, pp. 205-216
doi	https://doi.org/10.52842/conf.acadia.1990.205
summary	In an attempt to enhance the communication between architect and client, research was conducted in the use of computer modeling and video imaging techniques for the final architectural presentation process. By superimposing the painted building design from the CAD system onto a digitized image of the intended location, a composite image was achieved. These techniques have advantages in creating a realistic composite image of a proposed building design in its intended location within a short period of time. In order to provide more visual clues, a multiple view presentation format using a series of selected views (multiple views) was used. In addition, the research had further attempted to present the video- computer presentation in an animation sequence. The animation presentations were evaluated by comparing them with the multiple view presentations. Manual rendering and single viewpoint displays were also included in the comparisons in order to validate the results. Questionnaires were used to measure the capability of each presentation format to communicate the intended information to the audiences. The experiments were conducted with non-architecture subject groups in the local Bryan/College Station area.

source	Proceedings of the 3rd European Full-Scale Modelling Conference / ISBN 91-7740044-5 / Lund (Sweden) 13-16 September 1990, pp. 12-19
summary	The team from the LEA at Lausanne was not actually involved in the construction of the laboratory itself. During the past five years we have been discovering the qualities and limitations of the lab step by step through the experiments we performed. The method in which we use it is quite different from that of its creators. Since 1985 the external services has been limited to clients coming to the laboratory alone. We help them only with basic instructions for the use of the equipment. Most of these experiments are motivated by the excellent possibilities to discuss the design of a new hospital or home for elderly with the people directly affected by it, such as patients, nurses, doctors and specialists for the technical equipment. The main issues discussed in these meetings are of the dimensions and functional organisation of the spaces. The entire process for a normal room including construction, discussions and dismantling of the full-scale model is between three and five days. Today these types of experiments are occupying the lab only about twenty days a year.

title	Design Decision Making Using Pareto-Optimal Dynamic Programming
source	Berlin: Springer- Verlag, 1990. pp. 376-396
summary	When designing using the systems approach, the given system is decomposed into a number of subsystems, and for each subsystem a set of feasible alternatives is selected by the designer. A building design example is presented in which it is demonstrated that sufficient relevant solutions are generated in one pass of the dynamic programming procedure to give a good approximation to the Pareto set, thus offering designers sufficient choice in making a final selection. The relevant information is displayed in an intelligent manner so that designers can either make a final decision or else perceive what extra information they require

title	A Knowledge Based Computer- Aided Solar Design System
source	ASHRAE Transactions (American Society of Heating, Refrigerating and Air-Conditioning Engineers). Atlanta, GA: 1990. v.st.-96-2: [5] p. : ill. includes bibliography
summary	A knowledge based computer-aided architectural design system (KB-CAAD) for the schematic design and evaluation of passive solar buildings is presented. The presented tool is based on the integration of knowledge based and procedural simulation methods with any available CAAD system for building representation. The knowledge base contains the heuristic rules for the design of passive solar buildings. Whenever possible, the knowledge base guides the designer through the decision making process. However, if 'rules of thumb' are not acceptable for the particular design problem, the KB-CAAD tool guides the architect towards the optimal solution, by using a procedural simulation model. It is demonstrated, through a case study, that the proposed knowledge based design system not only leads to the design of better solar buildings, but that it takes less time and man-power to introduce the geometrical data that would be needed for a regular non-solar building representation

title	Flexibility of Buildings and Decision Making : A Financial Economical Design Decision Support System
source	1990. [12] : ill. includes bibliography
summary	A building can be considered as a complex long term production means of dwelling services. The various parts which compile the building have different life spans determined in the first place by the use of the building and secondly by the construction and materials used. Because in most cases, some fluctuation in the demand of the building market might be expected, buildings must have some flexibility. A model is presented by which the flexibility of buildings can be optimized in a financial economical way

title	Application of Expert Systems to Building Design Analysis and Evaluation
source	Building and Environment. 1990. vol.25: pp. 221-233
summary	This paper demonstrates the applicability of expert systems to design analysis and evaluation. Design is a field in which a large part of the processes involved is knowledge-based rather than computation-based. Much of this knowledge is experiential and as such lends itself to be encapsulated in an expert system. An analogy is made between analysis and interpretation and between evaluation and comparison of interpretations. Three examples of expert systems carrying out design analysis and evaluation in different domains are described. It is argued that a graphical interface and a model of the elements within the domain are essential parts of any design system

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.
