title	Making Designs Come Alive: Using Physically Based Modeling Techniques in Space Layout Planning
source	Proceedings of the Eighth International Conference on Computer Aided Architectural Design Futures [ISBN 0-7923-8536-5] Atlanta, 7-8 June 1999, pp. 245-262
summary	This paper introduces the concept of responsive design. It elaborates this concept as an approach to free form, adaptable, automated design applying physically based modeling techniques to the design process. Our approach attempts to bridge the gap between totally automated design and the free form brainstorming designers normally employ. We do this by automating the initial placement and sizing of design elements, with an interactive engine that appears alive and highly responsive. We present a method for applying these techniques to architectural space layout planning, and preliminary implementation details for a prototype system for developing rectangular, two-dimensional, single- story floor plans.

summary	The modelization of an architectural fact, generated through a CAD program, doesn't have only the purpose of generating a virtual electronic, but a constructive scale model of geometric nature. It also implies, a conceptualization level and a posture in front of the pattern that makes thinking in other fields besides the formally constructive, such as: the descriptive and geometric patterns, the communicational and the symbolic pattern. We should understand the way the constructive thought is done the message of the model, either for the relationship with the environment and with the human scale, depends not only upon the author, but his elections will be intrinsically related with his cultural baggage, besides its geometric, graphical and technicians data. These databases condition the result of the model, for this reason we analyzed these relationships looking for a good handling of the cultural codes, to achieve a complete communication of the model. In these moments of the "global village", we should consider this problematic as a visceral topic of the architectural representation, to achieve an effective communication, among different cultures, of the models represented.

title	VDU WORK IN DIFFERENT LIGHTING CONDITIONS
source	Full-scale Modeling and the Simulation of Light [Proceedings of the 7th European Full-scale Modeling Association Conference / ISBN 3-85437-167-5] Florence (Italy) 18-20 February 1999, pp. 7-28
summary	In order to avoid the disadvantages of purely subjective methods in a technical evaluation of daylight and artificial light systems, the Bartenbach LichtLabor developed new test methods which can determine objectively and quantitatively the visual or psycho-physiological stress connected with VDU work [1], depending on different lighting conditions. Daylight and artificial lighting systems were tested with these methods and compared by using the performances achieved by the test subjects. Some highly significant differences in performance done under the individual lighting systems became apparent and demonstrated that the visual stress or the physical or physiological fatigue from an ergonomic viewpoint depends largely on the lighting conditions at the workplace. This holds true for daylight systems (glare protection, re-directing lamellae, clear window as a control condition) as well as for purely artificial lighting systems where especially the choice of color temperature of the light and the used control gear (conventional or electronic) determine the resulting performance. Optimized lighting also positively affects the productivity and economicy for the design of workplaces that take the human factor into account.

title	MAKING LIGHT TANGIBLE: SIMULATION OF LIGHT DESIGN WITHIN ARCHITECTURAL EDUCATION
source	Full-scale Modeling and the Simulation of Light [Proceedings of the 7th European Full-scale Modeling Association Conference / ISBN 3-85437-167-5] Florence (Italy) 18-20 February 1999, pp. 1-6
summary	In times where computer-assisted representations dominate the “market” of visual simulation, the major strongholds of simulation in true size in conveying (artificial) light configurations have been observed. Though light cannot be “touched” due to its material absence the human eye reacts extremely sensitively to differing constellations. In matters of seconds differences are perceived and classified. Opening up a rift between the various simulation techniques, however, would not prove wise. The normal procedure still consists of trial positioning of lighting objects on site (i.e.: 1:1 simulation at building site). Regarding the effort this causes attempts as to gaining similar results by means of (partial) computer representations are worth considering. The degree of abstraction, however, might be too significant to make for conclusive decisions. In other words: Can the gap between imagination and translation thereof into reality be bridged? This contribution deals with the experimental implementation of artificial light in the full-scale lab and its possibilities regarding the 1:1 simulation at the Vienna University of Technology, with special attention to the didactic aspects related thereto.

title	Media in Mediation: Prospects for Computer Assisted Design Participation
doi	https://doi.org/10.52842/conf.acadia.1999.138
source	Media and Design Process [ACADIA ‘99 / ISBN 1-880250-08-X] Salt Lake City 29-31 October 1999, pp. 138-147
summary	One of the most consistent, powerful and philosophical ideas which has run like a silk thread through the short and erratic history of the development of computer aided architectural design is that of user participation in the design decision-making process. It is not an idea with which the architectural profession is particularly comfortable but it is, the authors claim, one which is central to the professional ethic and, therefore, to its ultimate survival. Design decision-making is, if addressed properly, a hugely, complex multi-variety, multi-person process on which precious little serious research has been focused. In the late 1960's the Design Methods Group in the USA and the Design Research Society in the UK formulated paper-based models of the design process and anticipated, in some regards with un-nerving accuracy, the way in which the application of information technologies would impinge beneficially on the process of design decision-making and, therefore, on the quality of the built environment. One concept expressed at that time was as follows: (•) the application of computers to the modeling and prediction of the cost and performance behavior of alternative design solutions allows subjective value judgements to be better informed and more explicitly audited, and that (•) such subjective value judgements should be made by those most affected by them, i.e. the future owners and users of buildings. // This paper is devoted to the critical re-examination of this concept, on the seminal research and development which has kept the notion alive over 30 years, and, most importantly in the context of the theme of ACADIA 1999, how the current advances in multimedia, virtual reality and internet access are not yet making its ubiquitous adoption inevitable: in short, a plea for Media in Mediation.

title	Integration and Application of Technologies CAD in a Regional Reality - Methodological and Formative Experience in Industrial Design and Products Development
source	III Congreso Iberoamericano de Grafico Digital [SIGRADI Conference Proceedings] Montevideo (Uruguay) September 29th - October 1st 1999, pp. 295-297
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	ArTbitrariness in Music
source	International Conference on Generative Art
summary	Evolution is now considered not only powerful enough to bring about the biological entities as complex as humans and conciousness, but also useful in simulation to create algorithms and structures of higher levels of complexity than could easily be built by design. In the context of artistic domains, the process of human-machine interaction is analyzed as a good framework to explore creativity and to produce results that could not be obtained without this interaction. When evolutionary computation and other computational intelligence methodologies are involved, every attempt to improve aesthetic judgement we denote as ArTbitrariness, and is interpreted as an interactive iterative optimization process. ArTbitrariness is also suggested as an effective way to produce art through an efficient manipulation of information and a proper use of computational creativity to increase the complexity of the results without neglecting the aesthetic aspects [Moroni et al., 2000]. Our emphasis will be in an approach to interactive music composition. The problem of computer generation of musical material has received extensive attention and a subclass of the field of algorithmic composition includes those applications which use the computer as something in between an instrument, in which a user "plays" through the application's interface, and a compositional aid, which a user experiments with in order to generate stimulating and varying musical material. This approach was adopted in Vox Populi, a hybrid made up of an instrument and a compositional environment. Differently from other systems found in genetic algorithms or evolutionary computation, in which people have to listen to and judge the musical items, Vox Populi uses the computer and the mouse as real-time music controllers, acting as a new interactive computer-based musical instrument. The interface is designed to be flexible for the user to modify the music being generated. It explores evolutionary computation in the context of algorithmic composition and provides a graphical interface that allows to modify the tonal center and the voice range, changing the evolution of the music by using the mouse[Moroni et al., 1999]. A piece of music consists of several sets of musical material manipulated and exposed to the listener, for example pitches, harmonies, rhythms, timbres, etc. They are composed of a finite number of elements and basically, the aim of a composer is to organize those elements in an esthetic way. Modeling a piece as a dynamic system implies a view in which the composer draws trajectories or orbits using the elements of each set [Manzolli, 1991]. Nonlinear iterative mappings are associated with interface controls. In the next page two examples of nonlinear iterative mappings with their resulting musical pieces are shown.The mappings may give rise to attractors, defined as geometric figures that represent the set of stationary states of a non-linear dynamic system, or simply trajectories to which the system is attracted. The relevance of this approach goes beyond music applications per se. Computer music systems that are built on the basis of a solid theory can be coherently embedded into multimedia environments. The richness and specialty of the music domain are likely to initiate new thinking and ideas, which will have an impact on areas such as knowledge representation and planning, and on the design of visual formalisms and human-computer interfaces in general. Above and bellow, Vox Populi interface is depicted, showing two nonlinear iterative mappings with their resulting musical pieces. References [Manzolli, 1991] J. Manzolli.

title	Design-Based on VR-Modeling of Environemntal Conditions
source	III Congreso Iberoamericano de Grafico Digital [SIGRADI Conference Proceedings] Montevideo (Uruguay) September 29th - October 1st 1999, pp. 126-129
summary	The research on CAD has been looking for a long time a creative contribution to architectural design, including recently the use of virtual-reality as an immersive modeling system, but without much practical results. However, contemporary architecture is increasingly including digital characteristics based more on cultural influences than on the use of electronic tools. This shows an evolution of the discipline in relation to digital media and apparently distant from environmental concerns. But the works and reflexions reveal a common convergence in the role of body in architecture as a pivot between virtual and local dimension of design. Based on that relationship we propose to take advantage of virtual-reality for modeling environmental conditions of the location in order to guide architectural design, using for example the potential of representing characteristics not visible in reality or to simulate time cycles. Sun displacement, wind direction, temperature ranges, topography and landscape are specific conditions in design that define energy consumption and human comfort. Such characteristics can establish optimal shapes crossing the different variables with timelines. VR-modeling and interactive control allow an spatial evaluation of environmentally efficient forms. That is showed through an exercise of housing in different locations of Chile. This merger between digital media and ecological concerns represents a crossing of contemporary cultural trends to motivate exploration of new geometries, supported on the potential of technology and on sustainable human development

source	Architectural Computing from Turing to 2000 [eCAADe Conference Proceedings / ISBN 0-9523687-5-7] Liverpool (UK) 15-17 September 1999, pp. 286-291
summary	This paper presents the results of two design studio elective courses offered to students in their second and third semester of studies at the Design Studio Department, "Universidad Politécnica de Valencia, UPV." Classes are based on a methodology that directly relates the language of architectural form and space, to the language of the specific software being used. Our focus is not only to discover what may be represented, but most important what may not, and why. We aim to point out the differences between architecture as perceived and experienced by a human being, and its digital representation as a computer data structure. At the Digital Design Studio, students are faced with a sequence of two projects so as to learn the basics of architecture, while developing their skill to build a digital representation of it. The first exercise within this CAD sequence is reading and analyzing a built project: a study of precedent. With this exercise we aim at two goals: to decipher the keys or parameters of architectural design, from drawings and pictures, trying to recognize an "architectural language"; and to learn a particular syntax of digital modeling. The second exercise is a project of a single family house within a narrow rectangular site and with only one street elevation. With this project we focus on the strong impact of stairs on the organization of functions and circulation, the illumination and ventilation of spaces with double heights and patios, and study the power of the section to express clearly the organization of spaces.

title	Integrated Computational Analysis of the Visual Environment in Buildings
source	Carnegie Mellon University, Pittsburgh
summary	Despite significant advances in the area of computational support for lighting design, lighting simulation tools have not been sufficiently integrated into the lighting design process. There is a significant body of designers who rely solely on their individual experience and do not use predictive simulation tools. Even when simulation tools are utilized, it is for design verification or presentation rather than for design support. A number of factors are thought to contribute to this lack of integration of simulation tools into the design process: a) Most existing tools rely on the problematic assumption implying the appropriateness of simplified models for the less complex early design and detailed simulation for the more complex later stages of design; b) They do not support an active exploration of design variables to satisfy desired performance criteria; c) They are not integrated with other building performance simulation models. This thesis addresses the above shortcomings by contributing to the field of visual analysis in the following areas, pertaining to the development of active, integrated design and performance simulation environments: - Implementation of a consistent and coherent, physically-based modeling approach, combining radiosity and ray-tracing methods for the simulation of light propagation. - Provision of design support both in terms of evaluation support for interpreting large amounts of computed data with diverse performance indices, and in terms of active design support to explore the relationships between the design variables and performance indices. - Integration of the lighting simulation module within a larger software environment (SEMPER) for the prediction and evaluation of multiple performance indicators (for energy, light, acoustics, etc.) in buildings.

summary	Recently, more and more researchers dedicated in the development of human computer interaction for CAD systems, such as gestural input of three dimensional coordinates (Lee, Hu, and Selker, 2005), flexible manipulation of NURBS objects (Cohen, Markosian, Zeleznik, Hughes, and Barzel, 1999; Emmerik, 1990), and the creation of force feedback (Wu, 2003). These research results indicated that the more intuitive control the device can provide in modeling process, the more creative solutions can be generated (Lee, Hu, and Selker, 2005; Schweikardt and Gross, 2000; Wu, 2003).

title	APPLICATION OF SPATIAL DESIGN ABILITY IN A POSTGRADUATE COURSE
source	Full-scale Modeling and the Simulation of Light [Proceedings of the 7th European Full-scale Modeling Association Conference / ISBN 3-85437-167-5] Florence (Italy) 18-20 February 1999, pp. 75-82
summary	Spatial Design Ability (SDA) has been defined by the author (1983) as the capacity to anticipate the effects (psychological impressions) that architectural spaces or its components produce in observers or users. This concept, which requires the evaluation of spaces by the people that uses it, was proposed as a guideline to a Masters Degree Course in Architectural Design at the Universidad Autonoma de Aguascalientes in Mexico. The theory and the exercises required for the experience needed a model that could simulate spaces in terms of all the variables involved. Full-scale modeling as has been tested in previous research, offered the most effective mean to experiment with space. A simple, primitive model was designed and built: an articulated ceiling that allows variation in height and shape, and a series of wooden panels for the walls and structure. Several exercises were carried out, mainly to experience cause -effect relationships between space and the psychological impressions they produce. Students researched into spatial taxonomy, intentional sequences of space and spatial character. Results showed that students achieved the expected anticipation of space and that full-scale modeling, even with a simple model, proved to be an effective tool for this purpose. The low cost of the model and the short time it took to be built, opens an important possibility for Institutions involved in architectural studies, both as a research and as a learning tool.

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.

summary	The development of a system capable of integrating a range of building design tools poses many challenges. Our framework for integrating design tools provides a structured approach, allowing individual parts to be developed independently. In this paper, we describe the overall framework and suggest a method for modeling and implementing each portion of the framework. Furthermore, we illustrate how such a system can integrate several design tools and be realized as a functional design system.

title	From 2D Base Map To 3D City Model
source	UMDS '02 Proceedings, Prague (Czech Republic) 2-4 October 2002, I.17-I.28
summary	Since 1997 Helsinki City Survey Division has proceeded in experimenting and in developing the methods for converting and supplementing current digital 2D base maps in the scale 1:500 to a 3D city model. Actually since 1986 project areas have been produced in 3D for city planning and construction projects, but working with the whole map database started in 1997 because of customer demands and competitive 3D projects. 3D map database needs new data modelling and structures, map update processes need new working orders and the draftsmen need to learn a new profession; the 3D modeller. Laser-scanning and digital photogrammetry have been used in collecting 3D information on the map objects. During the years 1999-2000 laser-scanning experiments covering 45 km2 have been carried out utilizing the Swedish TopEye system. Simultaneous digital photography produces material for orto photo mosaics. These have been applied in mapping out dated map features and in vectorizing 3D buildings manually, semi automatically and automatically. In modelling we use TerraScan, TerraPhoto and TerraModeler sw, which are developed in Finland. The 3D city model project is at the same time partially a software development project. An accuracy and feasibility study was also completed and will be shortly presented. The three scales of 3D models are also presented in this paper. Some new 3D products and some usage of 3D city models in practice will be demonstrated in the actual presentation.

title	Modeling Architectural Design Objectives in Physically Based Space Planning
doi	https://doi.org/10.52842/conf.acadia.1999.212
source	Media and Design Process [ACADIA ‘99 / ISBN 1-880250-08-X] Salt Lake City 29-31 October 1999, pp. 212-225
summary	Physically based space planning is a means for automating the conceptual design process by applying the physics of motion to space plan elements. This methodology provides for a responsive design process, which allows a designer to easily make decisions whose consequences immediately propagate throughout the design. It combines the speed of automated design methods with the flexibility of manual design methods, while adding a highly interactive quality and a sense of collaboration with the design itself. In our approach, the designer creates a space plan by specifying and modifying graphic design objectives rather than by directly manipulating primitive geometry. The plan adapts to the changing state of objectives by applying the physics of motion to its elements. For design objectives to have an effect on a physically based space plan, they need to be able to apply appropriate forces to space plan elements. Space planning can be separated into two problems, determining topological properties and determining geometric properties. Design objectives can then be categorized as topological or geometric objectives. Topological objectives influence the location of individual spaces, affecting how one space relates to another. Geometric objectives influence the size and shape of space boundaries, affecting the dimensions of individual walls. This paper focuses on how to model a variety of design objectives for use in a physically based space planning system. We describe how topological objectives, such as adjacency and orientation, can be modeled to apply forces to space locations, and how geometric objectives, such as area, proportion, and alignment, can be modeled to apply forces to boundary edges.

Towards the middle of the 30s, the city of Concepción developed an architecture distinctly colonial, neoclassical and eclectic. An earthquake in 1939 abruptly interrupted this scene, destroying the enterity of its most important buildings. The reconstruction of the city followed the manifestoes of Modern Architecture, consolidating the urban importance of buildings such us the Law Courts, the Railway Station and the Regional Government, that emerged as the new architectural and cultural heritage of the city. The project consisted on the modeling of eleven buildings of the modern architectural heritage, and on the generation of 42 virtual tours through the buildings that were finally edited on a 16' video. This video allows the spectator to make a virtual tour through the original modern heritage of the city, nowadays demolished, altered, and sometimes, even forgotten. This project pretends to widen the ways of comprehension of our cultural identity by using computer modelling and animation as a tool for the conservation of the architectural heritage; and creating a record that can be used as a reference and as an instrument of cultural difussion.

title	Towards Virtual Maps: On the Production of 3D City Models
source	GeoInformatics 2(5), pp. 10–13
summary	The growing demand for detailed city models has stimulated research on efficient 3D data acquisition. Over the past years, it has become evident that the automatic reconstruction of urban scenes is most promising if different types of data, possibly originating from different data sources are combined. In the approach presented in this paper the geometric reconstruction of urban areas is based on height data from airborne laser scanning and 2D GIS, which provides the ground plan geometry of buildings. Both data sources are used to estimate the type and parameter of basic primitives which in turn are combined to obtain complex building structures. The final output consists of 3D CAD models for the buildings. Using the reconstructed geometry, terrestrial images are mapped onto building facades to generate virtual city models.
