title	Energy optimized-ventilation constrained variable air volume system control
source	Automation in Construction 6 (5-6) (1997) pp. 463-470
summary	The analytical energy performance of an advanced energy optimized-ventilation constrained control approach to variable air volume systems was compared to four other controls. The other controls are either currently used or have been proposed in the literature. The advanced control demonstrated its potential to meet the ventilation requirements of ASHRAE Standard 62-1989 for every zone of the building with minimal energy consumption. The analytical work was carried out in a single story prototypical commercial building. The building was analyzed in five US cities to provide insight into the impact of climate on the performance of the advanced control. The advanced control consumed less total energy, considerably less in some cities, than the other four controls. The advanced control provides an excellent opportunity to apply to buildings new automation equipment and software never attempted before.

title	BIM and the Building Site: Assimilating digital fabrication within craft traditions
source	Digital Crafting [7th International Conference Proceedings of the Arab Society for Computer Aided Architectural Design (ASCAAD 2014 / ISBN 978-603-90142-5-6], Jeddah (Kingdom of Saudi Arabia), 31 March - 3 April 2014, pp. 27-36
summary	This paper outlines a particular component of very well known project: Antoni Gaudí’s Sagrada Família Basilica in Barcelona (1882– on-going but scheduled for completion in 2026). At the time of writing the realisation of the project has proceeded for 87 years since Gaudí's death (1852-1926). As a building site it has been a living laboratory for the nexus between traditional construction offsite manufacturing and digital fabrication since the computers were first introduced to the project:CAD in 1989 closely followed by CAAD two years later. More remarkably CAD/CAM commenced its significant influence in 1991 with the take-up of sem robotised stone cutting and carving. The subject of this paper is an elevated auditorium space that is one of the relatively few ‘sketchy’ areas that Gaudí bequeathed the successors for the design of his magnum opus.

title	A Study of Human Performance in Computer-Aided Architectural Design
source	International Journal of Human-Computer Interaction. 1989. vol. 1: pp. 69-107 : ill. includes bibliography
summary	This paper describes the development and application of a cognitively-based performance methodology for assessing human performance on computer-aided architectural design (CAAD) tasks. Two CAAD tasks were employed that were hypothesized to be different in terms of the underlying cognitive processes required for these tasks to be performed. Methods of manipulating task complexity within each of these tasks were then developed. Six architectural graduate students were trained on a commercially available CAAD system. Each student performed the two experimental design tasks at one of three levels of complexity. The data collected included protocols, video recordings of the computer screen, and an interactive script (time-stamped record of every command input and the computers textual response). Performance measures and methods of analysis were developed which reflected the cognitive processes used by the human during design (including problem- solving techniques, planning times, heuristics employed, etc.) and the role of the computer as a design aid. The analysis techniques used included graphical techniques, Markov process analysis, protocol analysis, and error classification and analysis. The results of the study indicated that some measures more directly reflected human design activity while others more directly reflected the efficiency of interaction between the computer and the human. The discussion of the results focuses primarily on the usefulness of the various measures comprising the performance methodology, the usefulness of the tasks employed including methods for manipulating task complexity, and the effectiveness of this system as well as CAAD systems in general for aiding human design processes

summary	The technology of knowledge-based systems can be found in texts on artificial intelligence. There is very little published so far on knowledge-based systems in architecture. To this end an international conference -- TIPS' 88: Knowledge-Based Design in Architecture -- was organized for August 1988 in Finland. Thirteen papers from that conference have been selected and edited for this monograph. They are grouped under five parts: Introduction; Schemas and Models; Processes and Knowledge; Modeling Buildings; and Creativity and Knowledge-Based Systems

title	Geometric Data Transfer Between CAD Systems : Solid Models
source	IEEE Computer Graphics and Applications September, 1989. vol. 9: pp. 57-71 : ill. includes bibliography.
summary	The CAD/CAM community is showing great interest in the development of data exchange standards. This article highlights some aspects of the work accomplished during the first phase of the ESPRIT project CAD1. Part of this work has resulted in a specification for the exchange of solid models, as well as in some pilot implementations of processors based on this specification. This work also contributes to the efforts of the International Standards Organization (ISO) in developing the Standard for the Exchange of Product Model Data (STEP). The authors present a summary of the CAD1 approach, addressing the structure of neutral files for solids, entities, and attributes supporting three kinds of representations; facilities for the transfer of parametric designs; referencing library components; and other general mechanisms. Also is described the current state of the specification and processor implementations. An example of a CAD1 neutral file is included. Results from cycle and intersystem solid model transfer tests are presented, showing the practicality of the CAD1 proposal. B-rep model transfer results are discussed in some detail. Finally, the authors outline the relationship of this work with standardization

doi	https://doi.org/10.52842/conf.caadria.2004.557
summary	This research has shown the difficulties associated with the GIS and the flooding evacuation path search through the huge searching space generated during the network analysis process. This research also presents an approach to these problems by utilizing a search process whose concept is derived from natural genetics. Genetic algorithms (GAs) have been introduced in the optimization problem solving area by Holland (1975) and Goldberg (1989) and have shown their usefulness through numerous applications. We apply GA and GIS to choice flooding evacuation path in metropolitan area in this study. We take the region of Shiji city in Taiwan for case. That could be divided into four parts. First, is to set the population of GA operation. Second, is to choose crossover and mutation. Third, is to calculate the fitness function of each generation and to select the better gene arrangement. Fourth, is to reproduce, after evolution, we can establish Flooding Evacuation Path that more reflect really human action and choice when flood takes place. However we can apply GA to calculate different evacuation path in different time series. Final, we compare and establish real model of evacuation path model to choosing flooding evacuation path.

title	Beyond the boundary object: sketches, computer games and blogs facilitating design development
source	CAADRIA 2008 [Proceedings of the 13th International Conference on Computer Aided Architectural Design Research in Asia] Chiang Mai (Thailand) 9-12 April 2008, pp. 544-551
doi	https://doi.org/10.52842/conf.caadria.2008.544
summary	Developing Frosts’ understanding of Leigh Star’s (Star 1989) concept of the boundary object this paper seeks to answer the question “would multiple boundary objects employed simultaneously facilitate design development?” The paper reflects on and critically reviews the design, implementation, and outcomes of a first year Architectural Design course that privileged architectural representation in the form of design sketches, blogs and contemporary computer gaming technology. The review process is supported by an in depth survey of students experiences both prior to and during the course. With a large number of students enrolled in the course (158) the findings from this survey can be seen to offer a statistical reliability which is in contrast to the more usual anecdotal approach.

title	The Electronic Design Studio: Architectural Knowledge and Media in the Computer Era [Conference Proceedings]
source	International Conference on Computer-Aided Architectural Design 1989/ ISBN 0-262-13254-0] (Massachusetts / USA), 1989, 505 p.
summary	Design is the computation of shape information that is needed to guide fabrication or construction of artifacts. But it is not so straightforward as, say, the computation of numerical information required to balance a checkbook. This is partly because algebras of shapes are not as well understood and precisely formalized as algebras of numbers, partly because the rules for carrying out shape computations tend to be fluid and ill defined and partly because the predicates that must be satisfied to achieve successful termination are often complex and difficult to specify. For centuries architects have carried out shape computations by hand, using informal procedures and the simplest of tools. Over the last two decades though, they have made increasing use of more formal procedures executed by computers. It is still too early to be sure of the gains and losses that follow from this development, but there is no doubt that it raises some challenging questions of architectural theory and some perplexing issues for those concerned with the future of architectural education. This book frames those issues and provides a diversity of perspectives on them. Its contents were initially presented at the CAAD Futures 89 Conference-an international gathering of researchers and teachers in the field of computer-aided architectural design which was jointly sponsored by the Harvard Graduate School of Design and the MIT Department of Architecture and held in Cambridge, Massachusetts, in July 1989. There are four major sections: Theoretical Foundations, Knowledge-Based Design Tools, Information Delivery Systems, and Case Studies: Electronic Media in the Design Studio. In a representative collection of current views, over thirty extensively illustrated papers discuss the experiences of universities in the USA, Europe, Japan, Israel, Canada, and Australia, articulate present theoretical and practical concerns, provide criticism of media and methods, and suggest directions for the future. Architectural educators and architects concerned with the effect of computer technology on the design process will find here an indispensable reference and a rich source of ideas. This book was itself prepared in an electronic design studio. Composition and typography, most image collection and placement, and such editing as was practical within this publishing format, were all performed digitally using Macintosh computers at the Harvard Graduate School of Design during a period of a few weeks in 1989.

summary	Traditional computer drafting systems and three- dimensional geometric modeling systems work in bottom-up fashion. They provide a range of graphic primitives, such as vectors, arcs, and splines, together with operators for inserting, deleting, combining, and transforming instances of these. Thus they are conceptually very similar to word processors, with the difference that they operate on two- dimensional or three-dimensional patterns of graphic primitives rather than one-dimensional strings of characters. This sort of system is effective for input and editing of drawings or models that represent existing designs, but provides little more help than a pencil when you want to construct from scratch a drawing of some complex object such as a human figure, an automobile, or a classical column: you must depend on your own knowledge of what the pieces are and how to shape them and put them together. If you already know how to draw something then a computer drafting system will help you to do so efficiently, but if you do not know how to begin, or how to develop and refine the drawing, then the efficiency that you gain is of little practical consequence. And accelerated performance, flashier color graphics, or futuristic three-dimensional modes of interaction will not help with this problem at all. By contrast, experienced expert graphic artists and designers usually work in top-down fashion-beginning with a very schematic sketch of the whole object, then refining this, in step-by-step fashion, till the requisite level of precision and completeness is reached. For example, a figure drawing might begin as a "stick figure" schema showing lengths and angles of limbs, then be developed to show the general blocking of masses, and finally be resolved down to the finest details of contour and surface. Similarly, an architectural drawing might begin as a parti showing just a skeleton of construction lines, then be developed into a single-line floor plan, then a plan showing accurate wall thicknesses and openings, and finally a fully developed and detailed drawing.

title	Computer-Aided Design of Precast Building System
source	Proceedings of the International Conference on CAD/CAM and AMT. December, 1989. pp. 1-5 : some ill. includes bibliography
summary	The paper describes an expert system for computerized design of precast building components for a given architectural solution. The system receives the layouts and evaluations of the building as input, indicates the location of structural supports, breaks down the floors and walls into the elements to be prefabricated, and finally generates detailed production drawings for each element. Design stages are governed by the specific features of the prefabrications system to be employed. Design alternatives are also evaluated in the course of the process. The paper reviews the principles of the system and the particular features of the computer program employed for this purpose

source	International Conference on Computer-Aided Architectural Design 1989/ ISBN 3-528-08821-4 / Zürich (Switzerland), July 1991, 594 p.
summary	Computer Aided Architectural Design (CAAD) is the art of design and computation. Since the establishment of the CAAD futures organization in 1985, experts meet every two years to explore the state-of-the-art and postulate on future development in Computer Aided Architectural Design. The fourth international CAAD futures conference took place in July 1991 in Zürich at the Swiss Federal Institute of Technology (ETH Zürich), organized by the Chair for CAAD. More than 220 participants from 25 countries attended the conference. Presentation topics were education, research, and application. The mission of CAAD futures '91 was to provide an international forum for the dissemination and discussion of future oriented developments and new experiences in the field of Computer Aided Architectural Design. This book is one result of the conference and is divided into three sections: Education, Research and Application. This international overview of the 1991 state-of-the- art in Computer Aided Architectural Design will serve as a reference for design teachers, researchers, and application developers interested in CAAD.

doi	https://doi.org/10.52842/conf.acadia.1994.197
summary	This paper describes the use of electronic space in a fourth year undergraduate architectural design studio. It attempts to address the importance of developing a design process that is redefined by the use of computing, integrating concept and perception. This goal is set in the studio exercise, an international student design competition to design an addition to the school of architecture at the original Bauhaus/Weimar. The studio involved re-evaluating the Bauhaus principles of integrating the artist and the craftsman, but in contemporary or post-industrial terms. In 1989 the Wall came down. Seamless access of western telecommunications and media became greatly responsible for the crumbling of the rigid machine-age soviet technocracy; and with it, the former east German city of Weimar, home to the first Bauhaus, was once again a living part of architectural history. When the Association of Collegiate Schools of Architecture announced an international student competition to design a new addition to the school of architecture at the original Bauhaus/Weimar, we immediately decided that this should be an Electronic Bauhaus.

doi	https://doi.org/10.52842/conf.ecaade.1989.x.a0t
summary	The efficiency of images in communication between humans has so far been used almost exclusively by TV and other mass medias. The costs have been too great to encourage the use of images in the financially restricted everyday practice of architecture. With a range of application programs for the Apple Macintosh II the vision has come close to reality. It is now possible to create guided walks with the chance to choose different routes and views in a model of buildings and surroundings in 256 colour graphics. The makers of these programs may not have foreseen this use for their products and that is why it takes quite a lot of effort to make all the necessary images. With some supplementary routines however, this will be made much easier. Animation can also be used to visualize different processes inside a building. We have been studying the working environment in mechanical industry. The goal of this project is to make communication possible between the workers at all levels of an organization in planning changes and has so far been very successful. The use of this technique is only limited by our imagination and funding. Some examples to be tested in the near future are "Escape at a fire", "Animation of a Dairy", "Traffic situations in a parking lot-, "CAD-working place" and others. One of the difficulties in interactive planning with users has been to come close enough to their reality. With animated images it is possible to visualize what is going to happen and what it is going to look like in a more understandable way. In education this must be a challenging possibility. Changes and processes are some of the most difficult subjects to describe and explain! The software used is a handful of individual programs which, thanks to the graphics standards of the Macintosh, can exchange data with each other.

summary	Should we teach CAAD? - yes, but why? Answer to this question is clear too. Question three - "when?" - on the 5, 6 and 7 term. Why so rate? - it is a compromise because "Architecture is an art" and students of architecture should know how to make a project without computers. How to teach CAAD? - we should teach haw to use professional computer programs and not programming. We must work out a new manual for architects. It should be constructed in such a way as to correspond to consecutive steps of the architectural design process.

summary	Simple s-plane maps are used to graphically reveal interactions of performance requirements and constraints thus providing a control system designer insight into performance trade-offs. Two well-known but powerful ideas underlie this approach: (a) the characteristic equation of an nth-order system can be fully described by the specification of n variables and (b) any dynamic performance requirement or constraint can be expressed in terms of 2n variables of which n describe the open-loop and n describe the closed-loop characteristic equations. An example illustrates the application of the approach to controller design

doi	https://doi.org/10.52842/conf.acadia.1989.103
summary	Replacement operations, where an element at any topological level may be replaced by another element at the same or different topological level, are defined. Their potential as design tools which may be incorporated in a CAD system is investigated and demonstrated through the experimental implementation of two such operations in MARCOS, a Modeling Architectural Compositions System. MARCOS has been written in C. It is highly interactive and runs on an Apple Macintosh IIx. The two operations which have been implemented are the face -> volume and volume -> volume replacements. They were chosen for their potential as generators of architectural forms. Examples of architectural compositions produced through the use of replacement operations are also illustrated.
