title	Virtual Reality in the Design Studio: The Eindhoven Perspective
doi	https://doi.org/10.52842/conf.ecaade.1999.169

summary	Since 1991 Virtual Reality has been used in student projects in the Building Information Technology group. It started as an experimental tool to assess the impact of VR technology in design, using the environment of the associated Calibre Institute. The technology was further developed in Calibre to become an important presentation tool for assessing design variants and final design solutions. However, it was only sporadically used in student projects. A major shift occurred in 1997 with a number of student projects in which various computer technologies including VR were used in the whole of the design process. In 1998, the new Design Systems group started a design studio with the explicit aim to integrate VR in the whole design process. The teaching effort was combined with the research program that investigates VR as a design support environment. This has lead to increasing number of innovative student projects. The paper describes the context and history of VR in Eindhoven and presents the current set-UP of the studio. It discusses the impact of the technology on the design process and outlines pedagogical issues in the studio work.

summary	This paper presents the searching of new building modes for the knowledge of design in curriculum workshops at Facultad de Arquitectura, Diseno y Urbanismo of the Universidad Nacional del Litoral the proposed “research action” program articulates longitudinally in the three cycles of the career, understanding architecture as metaknowledge within a new paradigm of subjectivity, complexity and multidimensionality. In other words, it is recognized a new scenery tending to modify didactic relations. This experimental field looks for conscientious equilibrium between “written culture/audiovisual culture”, and “analog instruments/digital media”. We focus our interest on the “machine interacting with and for men”, looking for harmonious synthesis through a new way of thinking, to allow “real progress”. For turning this idea into action, we organized an alternative and plural team-work in architecture. We called it “experimental workshop”. In this first level the students worked. On a preliminary plan of a “kindergarden”. They developed a divergent process through the 3D simulations (using the software 3DS MAX v2), scale models and sensible sketches. For conclusions, the paper addresses the characteristics of the pedagogic model used and the results achieved.

summary	The insert of the digital technologies in the atmosphere Áulico has left generalizing in a significant way. An example constitutes it the high percentage of students that they manifested general knowledge in the software handling in the introductory course of visual communication, as well as the voluntary presentation of practical works developed with digital means. The necessity of an answer to the requirements that arise of the students sinks to the certainty of a pedagogic compatibility among the matter to try and the teaching attended by the personal computer that would increase the Iconidad and the understanding of a topic of certain complexity like it is the geometry of the space. An educational program designed for the teaching of the Sistema Monge whose general characteristics were presented in the II Ibero-American Seminar of Digital Graph and that it will be applied as experience pilot in the course 2000, it will allow us to respond to the following queries: what place it will be given to the educational program in the formation process in connection with the other pedagogic means.

title	The use of genetic programming for applications in the field of spatial composition
source	International Conference on Generative Art
summary	Architectural design teaching using computers has been a preoccupation of CECA since 1991. All design tutors provide their students with a set of models and ways to form, and we have explored a set of approaches including cellular automata, genetic programming ,agent based modelling and shape grammars as additional tools with which to explore architectural ( and architectonic) ideas.This paper discusses the use of genetic programming (G.P.) for applications in the field of spatial composition. CECA has been developing the use of Genetic Programming for some time ( see references ) and has covered the evolution of L-Systems production rules( coates 1997, 1999b), and the evolution of generative grammars of form (Coates 1998 1999a). The G.P. was used to generate three-dimensional spatial forms from a set of geometrical structures .The approach uses genetic programming with a Genetic Library (G.Lib) .G.P. provides a way to genetically breed a computer program to solve a problem.G. Lib. enables genetic programming to define potentially useful subroutines dynamically during a run .* Exploring a shape grammar consisting of simple solid primitives and transformations. * Applying a simple fitness function to the solid breeding G.P.* Exploring a shape grammar of composite surface objects. * Developing grammarsfor existing buildings, and creating hybrids. * Exploring the shape grammar of abuilding within a G.P.We will report on new work using a range of different morphologies ( boolean operations, surface operations and grammars of style ) and describe the use of objective functions ( natural selection) and the "eyeball test" ( artificial selection) as ways of controlling and exploring the design spaces thus defined.

title	Before the Digital Design Studio
source	III Congreso Iberoamericano de Grafico Digital [SIGRADI Conference Proceedings] Montevideo (Uruguay) September 29th - October 1st 1999, pp. 247-252
summary	This paper contains some observations which derive from our work as Studio Professors . In the last years, studios are in a transition phase with the progressive introduction of computers in later stages of the design process. The initiative generally belongs to students rather than to studio masters, since the former are aware that a knowledge of CAD systems will make them able to get work in architects offices. It is the first few Studios that will guide the student in forming a conception of what is architecture . Therefore, we have observer more attentively the way in which he establishes his first competence as a designer. We believe it is useful to clarify design training before we can integrate computers into it. The ways we all learn to design and which we transmit in the Studio were obviously created a long time ago, when Architecture became a subject taught in Schools, no longer a craft to be acquired under a master. The conception of architecture that the student forms in his mind is largely dependent on a long tradition of Beaux-Arts training which survives (under different forms) in Modern Architecture. The methods he or she acquires will become the basis of his creative design process also in professional life. Computer programmes are designed to adapt into the stages of this design process simply as time saving tools. We are interested in finding out how they can become an active part in the creative process and how to control this integration in teaching. Therefore, our work deals mainly with the tradition of the Studio and the conditioning it produces. The next step will be to explore the possiblities and restrictions that will inevitably issue from the introduction of new media.

title	Sunlight Energy Graphic and Analytic Control in 3D Modelling
doi	https://doi.org/10.52842/conf.ecaade.1999.733
source	Architectural Computing from Turing to 2000 [eCAADe Conference Proceedings / ISBN 0-9523687-5-7] Liverpool (UK) 15-17 September 1999, pp. 733-738
summary	Linking solar positions with architecture is a traditional idea, but the use of graphical tools to control sunlight in urban surroundings or buildings is relatively recent. A three-dimensional working environment like the computer offers a new dimension to verify the relationships between the sun and the architecture. This paper shows a new way to calculate the incidence of solar energy in architectural environments using computer 3D modelling. The addition of virtual space visualisation to the analytic computation brings a new tool that simplifies the technical study of sunlight. We have developed several programs based upon the three-dimensional construction of the solar vault and the obstructing objects for a defined position. The first one draws the solar vault for a defined range of dates according to latitude, that is the basis of the energetic calculation. The second program computes the obstruction, i.e. the solar regions that are obstructed by any object. Finally, the third one, allow us to define an orientation to compute the energy that arrives to the analysed positioning. The last program returns the result of calculation in several ways: it shows the amount of energy through colours and makes a list of solar hours according to its energy.

summary	In the very young discipline of Virtual Reality Applications only a few reports are available about using this technology for periods longer than in experimental setups. This paper describes experiences made during five years of usage of Virtual Reality (VR) in educational training for architects. About 100 different people were working with our systems during this period. Three programs were developed at Bauhaus University with the aim of teaching architectural students to design in three-dimesional environments. The first program called voxDesign is based on the metaphor of voxels. The second program, planeDesign, uses rectangualar planes to describe room-like situations. An other program vram for the user orientated description of flexible and own interfaces and environments is current under construction, a first verson is presented at the international computer exhibition ìCeBitî in 1999. All programs force the users to design in a 1:1 scale, that means that the design and the feedback actions are coupled in an embodied way. A real walking metaphor is used for navigation. The experiences made by users are explained too.

title	Structural Approach to the Organization of Information: A Teaching Experiment at SEU
doi	https://doi.org/10.52842/conf.caadria.1999.153
source	CAADRIA '99 [Proceedings of The Fourth Conference on Computer Aided Architectural Design Research in Asia / ISBN 7-5439-1233-3] Shanghai (China) 5-7 May 1999, pp. 153-159
summary	Design studio still plays a very important role in architectural design education today since teachers and students can exchange their thinking directly. In the whole teaching/learning process, there are a lot of information to be exchanged between the teachers and the students. How to organize the information and record the whole teaching/learning process is very interesting to us. The increasing use of CAD raises some problems with its advantages when the amount of compute-files becomes very big and they are in different formats. In the third year design studio teaching in the academic year 1998/99 at Department of Architecture in Southeast University, we try to use WWW techniques and features to organise the design information. We try to integrate the teaching programme, the project information, the reference material and the students' work together, to record and monitor the teaching process. Since the teaching programme is clearly organised, we could use some strategies and ideas to control the organisation of file storage and presentation. It creates the basis for the further development of applying network to aid the studio teaching.

title	Generating digital music with DirectCsound & VMCI
source	International Conference on Generative Art
summary	This paper concerns two computer-music programs: DirectCsound, a real-time version of the well-known sound-synthesis language Csound, and VMCI, a GUI program that allow the user to control DirectCsound in real-time. DirectCsound allows a total live control of the synthesis process. The aim of DirectCsound project is to give the user a powerful and low-cost workstation in order to produce new sounds and new music interactively, and to make live performances with the computer. Try to imagine DirectCsound being a universal musical instrument. VMCI (Virtual Midi Control Interface) is a program which allows to send any kind of MIDI message by means of the mouse and the alpha-numeric keyboard. It has been thought to be used together with DirectCsound, but it can also be used to control any MIDI instrument. It provides several panels with virtual sliders, virtual joysticks and virtual-piano keyboard. The newer version of the program (VMCI Plus 2.0) allows the user to change more than one parameter at the same time by means of the new Hyper-Vectorial-Synthesis control. VMCI supports seven-bit data as well as higher-resolution fourteen-bit data, all supported by the newest versions of Csound.

summary	The experience to present is begun and developed during the academic year 1998, together to the course of IV pupils level of the Industrial Design career in the Universidad del Bío-Bío, labor that I have continued assuming during the present year, with a new youths generation. We have accomplished our academic work taking as original of study and base, the industrial and economic situation of the VIII Region, context in the one which we outline and we commit our needs formative as well as methodological to the teaching of the discipline of the Industrial Design. Consequently, we have defined a high-priority factor among pupils and teachers to reach the objectives and activities program of the course, the one which envisages first of all a commitment of attitude and integrative reflection among our academic activity and the territorial human context in the one which we inhabit. In Chile the activity of the industrial designer, his knowledge and by so much his capacity of producing innovation, it has been something practically unknown in the industrial productive area. However, the current national development challenges and the search by widening our markets, they have created and established a conscience of the fact that the Chilean industrial product must have a modern and effective competitiveness if wants be made participates in segments of the international marketing. It is in this new vision where the design provides in decisive form to consider and add a commercial and cultural value in our products. To the university corresponds the role of transmitting the knowledge generated in his classrooms toward the society, for thus to promote a development in the widest sense of the word. Under this prism the small and median regional industry in their various areas, have not integrated in the national arrangement in what concerns to the design and development of new and integral products. The design and the innovation as motor concept for a competitiveness and permanency in new markets, it has not entered yet in the entrepreneurial culture. If we want to save this situation, it is necessary that the regional entrepreneur knows the importance of the Design with new models development and examples of application, through concrete cases and with demands, that serve of base to demonstrate that the alliance among Designer and Industry, opens new perspectives of growth upon offering innovation and value added factors as new competitiveness tools. Today the communication and the managing of the information is a strategic weapon, to the moment of making changes in a social dynamics, so much at local level as global. It is with this look that our efforts and objective are centered in forming to our pupils with an integration speech and direct application toward the industrial community of our region, using the communication and the technological information as a tool validates and effective to solve the receipt in the visualization of our projects, designs and solutions of products. As complement to the development of the proposed topic will be exhibited a series of projects accomplished by the pupils for some regional industries, in which the three dimensional modeling and the use of programs vectoriales demonstrate the efficiency of communication and comprehension of the proposals, its complexity and constructive possibilities.

title	The application of computer simulation techniques to the design and preservation of a national monument
source	IBPSA, Kyoto, vol 2, 555-562
summary	The paper outlines a two-year research program where Radiance was used in the conversion of Empress Place, a national monument in Singapore, into an Asian Civilisation Museum. The paper describes how the research team fine-tune the modeling and software settings to cope with some of the contextual issues of design. Inaddition, the paper discusses how Radiance could be used to aid the design of the building. One of the more difficult tasks the researchers faced was to model and validate some of the daylighting control devices that are part of the existing features of the building. And to design new control devices that are architecturally consistent with the building. Working with the design team, options and strategies are studied. At the end, contrary to the original beliefs of the architect, and much to the liking of the curator, it has been demonstrated that, carefully designed, daylighting could be introduced into the gallery and that it will enhance the quality of the interior spaces. The building is currently under construction.

summary	This paper outlines a two years research program that the team attempted to apply one of the most powerful computational lighting simulation software RADIANCE to assist in daylighting design of an actual building in the tropics. The validation studies, which were carried out in the Asian Civilisation Museum (ACM) in Singapore, show that Radiance can be used to predict the internal illuminance with a high degree of accuracy under overcast sky conditions without external obstruction. The experimental application of Radiance to daylighting investigation of the ACM further supports its capabilities as well as its accuracy. Using Radiance to study two daylighting control options (curtains and louvers), it can be found that louvers are more effective than curtains as daylighting control devices, and that the angle of the louvers has more effect than their reflectance on daylight penetration and distribution.

summary	The graduation course of Architecture and Urbanism of the Federal University of Santa Catarina makes use of informatic tecnology in several teaching and research activities. This technology supports initial data proccessing, analysis, evaluations, simulations, and project development both in architecture and urban fields. Aiming to stimulate and improve the use of computer techniques in graduation courses, the INFOARQ group, belonging to the 'LABMICRO' developed the project 'Digital Floripa'. This project is an CD image data basis, with digital aerophotographs Florianópolis’ city taken, from the aerophotogrametric data of 1994. This project aims to facilitate image's access to teachers, students and researchers, to allow use of photos and scales, and to make possible the development of new alternatives interventions. A navegator program called 'DIGITAL INDEX'supports the user in the image's search and creates a same graphic interface. This project also acts as basis for research development wich aims to analyse and develop tutorial proceedures to access the utilization of the data images basis.

source	AVOCAAD Second International Conference [AVOCAAD Conference Proceedings / ISBN 90-76101-02-07] Brussels (Belgium) 8-10 April 1999, pp. 189-204
summary	This paper reports on a project that aims to formulate a CAAD program model in Distance Education (Learning/Teaching) framework, to be applied and implemented in future settings at Open Universities worldwide. The methodology used to establish the CAAD program model consisted of a worldwide literature review on the subject of Distance Education and Open Universities. It also involved an assessment of the methods and means used in the delivery of materials to students enrolled at Open Universities, together with an analysis of the current program of study and subject related courses. The methods of this investigation consisted of a comparative analysis between the existing models of teaching process at Open Universities and how it relates to CAAD in architecture schools. The study endeavored to examine several issues that were found to be key factors in any Open University system, namely: the methods of study, program of study, student type/body, academic/degree requirements, and residency/academic calendars. While attempting to establish a conceptual CAAD program model, this study investigated several questions concerning the efficiency of CAAD teaching in Distance Education. One of the study objectives was to determine which factors were mostly needed to effectively integrate CAAD in DE as a new program in Open Universities. In addition, how would these factors affect the design of CAAD courses in OU systems as a new DE program area? And what structural elements would be most affected by these factors? Another objective of this study was to determine to what extent the new CAAD program model in tandem with staff, learning environment, and administered materials would be effective in generating supplementary strategies in the virtual design studio. A third objective was to evaluate the personal computer station as an alternative design studio space in future settings of schools of architecture. Consequently, the principle objective of this study was to develop and establish a CAAD program model to be adopted by Open Universities as a new subject area in DE. Mainly, the study attempted to locate the areas where CAAD teaching excels in the context of virtual design studio of OU system.

summary	While AutoCAD is not directly associated with Office 2000, the AutoCAD object model is now a powerful tool with VBA behind it, allowing graphic designers to control their environment programmatically. It is therefore to be released concurrently with the other Wrox Office 2000 Programmer References. Using VBA (Visual Basic for Applications), the user can program his or her own programs in what is essentially a subset of the Visual Basic programming languages. This allows you to automate a lot of the graphical tasks performed daily - such as performing a hundred complex graphical manipulations.

title	Automated Cost Analysis of Concept Design BIM Models

summary	AUTOMATED COST ANALYSIS OF CONCEPT DESIGN BIM MODELS Interoperability: BIM models and cost models This paper introduces the automated cost analysis developed for the General Services Administration (GSA) and the analysis results of a case study involving a concept design courthouse BIM model. The purpose of this study is to investigate interoperability issues related to integrating design and analysis tools; specifically BIM models and cost models. Previous efforts to generate cost estimates from BIM models have focused on developing two necessary but disjoint processes: 1) extracting accurate quantity take off data from BIM models, and 2) manipulating cost analysis results to provide informative feedback. Some recent efforts involve developing detailed definitions, enhanced IFC-based formats and in-house standards for assemblies that encompass building models (e.g. US Corps of Engineers). Some commercial applications enhance the level of detail associated to BIM objects with assembly descriptions to produce lightweight BIM models that can be used by different applications for various purposes (e.g. Autodesk for design review, Navisworks for scheduling, Innovaya for visual estimating, etc.). This study suggests the integration of design and analysis tools by means of managing all building data in one shared repository accessible to multiple domains in the AEC industry (Eastman, 1999; Eastman et al., 2008; authors, 2010). Our approach aims at providing an integrated platform that incorporates a quantity take off extraction method from IFC models, a cost analysis model, and a comprehensive cost reporting scheme, using the Solibri Model Checker (SMC) development environment. Approach As part of the effort to improve the performance of federal buildings, GSA evaluates concept design alternatives based on their compliance with specific requirements, including cost analysis. Two basic challenges emerge in the process of automating cost analysis for BIM models: 1) At this early concept design stage, only minimal information is available to produce a reliable analysis, such as space names and areas, and building gross area, 2) design alternatives share a lot of programmatic requirements such as location, functional spaces and other data. It is thus crucial to integrate other factors that contribute to substantial cost differences such as perimeter, and exterior wall and roof areas. These are extracted from BIM models using IFC data and input through XML into the Parametric Cost Engineering System (PACES, 2010) software to generate cost analysis reports. PACES uses this limited dataset at a conceptual stage and RSMeans (2010) data to infer cost assemblies at different levels of detail. Functionalities Cost model import module The cost model import module has three main functionalities: generating the input dataset necessary for the cost model, performing a semantic mapping between building type specific names and name aggregation structures in PACES known as functional space areas (FSAs), and managing cost data external to the BIM model, such as location and construction duration. The module computes building data such as footprint, gross area, perimeter, external wall and roof area and building space areas. This data is generated through SMC in the form of an XML file and imported into PACES. Reporting module The reporting module uses the cost report generated by PACES to develop a comprehensive report in the form of an excel spreadsheet. This report consists of a systems-elemental estimate that shows the main systems of the building in terms of UniFormat categories, escalation, markups, overhead and conditions, a UniFormat Level III report, and a cost breakdown that provides a summary of material, equipment, labor and total costs. Building parameters are integrated in the report to provide insight on the variations among design alternatives.

title	Internet-based collaborative design evaluation : an architect's perspective
source	Harvard University
summary	This research aims at developing a design evaluation system that employs a Product Model as the logical basis for integrating building design and construction processes. The system is implemented with Java language, which allows the system to work over the Internet. Accordingly, the system helps architects to collaborate with remote participants. Thus, this design evaluation system is a building performance evaluator like DOE-2, RADIANCE, HVAC, and the Automated Building Code Checker. This research, however, is mainly concerned with an architect's view during the schematic design and design development stage, while the existing design evaluation systems cover other special consultants' views such as those of HVAC designers, structural engineers, and contractors. From an architect's view, this evaluation system checks the compliance of design objects represented by means of physical objects such as walls and windows and conceptual objects such as rooms as well, to the design criteria focused on accommodating human behavior, rather than other building performances such as sustaining building structures and maintaining indoor livability. As such, the system helps designers analyze and evaluate design solutions according to their original intent. The innovative points of this research lie in the following: (1) Unlike other inquiries, it addresses a systematic evaluation of building design from an architect's view focusing on the experiential quality of the built environment. This research demonstrates that such an evaluation becomes available by introducing human activity-based evaluation. (2) It can take a multi-agenda for several groups of different interests by providing an Aspect Model based on human activity-centered systematic translation of their design considerations and 3D model-based graphical representations into system readable ones. (3) As a result, it addresses the possibility of expanding the capability of the design evaluator from a mere code checker to a general design evaluator while simultaneously, enhancing the availability from stand alone to Internet based networking.
