title	On the Thermal Interaction of Building Structure and Heating and Ventilating System
source	Eindhoven University of Technology
summary	In this dissertation, developments in the field of building performance evaluation tools are described. The subject of these tools is the thermal interaction of building structure and heating and ventilating system. The employed technique is computer simulation of the integrated, dynamic system comprising the occupants, the building and its heating and ventilating system. With respect to buildings and the heating and ventilating systems which service them, the practical objective is ensuring thermal comfort while using an optimum amount of fuel. While defining the optimum had to be left for other workers, the issue of thermal comfort is addressed here. The conventional theory of thermal comfort in conditions characteristic for dwellings and offices assumes steady-state conditions. Yet thermal conditions in buildings are seldom steady, due to the thermal interaction between building structure, climate, occupancy, and auxiliary systems. A literature rewiew is presented regarding work on thermal comfort specifically undertaken to examine what fluctuations in indoor climate may be acceptable. From the results, assessment criteria are defined. Although its potentials reach beyond the area of Computer Aided Building Design, a description is given of building and plant energy simulation within the context of the CABD field of technology. Following an account of the present state-of-the-art, the choice for starting from an existing energy simulation environment (ESPR) is justified. The main development areas of this software platform - within the present context - are identified as: fluid flow simulation, plant simulation, and their integration with the building side of the overall problem domain. In the field of fluid flow simulation, a fluid flow network simulation module is described. The module is based on the mass balance approach, and may be operated either in standalone mode or from within the integrated building and plant energy simulation system. The program is capable of predicting pressures and mass flows in a user-defined building / plant network comprising nodes (ie building zones, plant components, etc) and connections (ie air leakages, fans, pipes, ducts, etc), when subjected to flow control (eg thermostatic valves) and / or to transient boundary conditions (eg due to wind). The modelling and simulation techniques employed to predict the dynamic behaviour of the heating and ventilating system, are elaborated. The simultaneous approach of the plant and its associated control is described. The present work involved extensions to the ESPR energy simulation environment with respect to robustness of the program, and with respect to additional plant simulation features, supported plant component models and control features. The coupling of fluid flow, plant side energy and mass, and building side energy simulation into one integrated program is described. It is this "modular-simultaneous" technique for the simulation of combined heat and fluid flow in a building / plant context, which enables an integral approach of the thermal interaction of building structure and heating and ventilating system. A multi stage verification and validation methodology is described, and its applicability to the present work is demonstrated by a number of examples addressing each successive step of the methodology. A number of imaginary and real world case studies are described to demonstrate application of the present work both in a modelling orientated context and in a building engineering context. Then the general conclusions of the present work are summarized. Next and finally, there are recommendations towards possible future work in the areas of: theory, user interface, software structure, application, and technology transfer.

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	Neural Networks for Estimating Wind Pressure on Complex Double-Curved Facades
doi	https://doi.org/10.52842/conf.ecaade.2023.2.639
source	Dokonal, W, Hirschberg, U and Wurzer, G (eds.), Digital Design Reconsidered - Proceedings of the 41st Conference on Education and Research in Computer Aided Architectural Design in Europe (eCAADe 2023) - Volume 2, Graz, 20-22 September 2023, pp. 639–647
summary	Due to their complex geometry, it is challenging to assess wind effects on the freeform, double-curved building facades. The traditional building code EN 1991-1-4 (730035) only accounts for basic shapes such as cubes, spheres, and cylinders. Moreover, even though wind tunnel measurements are considered to be more precise than other methods, they are still limited by the number of measurement points that can be taken. This limitation, combined with the time and resources required for the analysis, can limit the ability to fully capture detailed wind effects on the whole complex freeform shape of the building. In this study, we propose the use of neural network models trained to predict wind pressure on complex double-curved facades. The neural network is a powerful data-driven machine learning technique that can, in theory, learn an approximation of any function from data, making it well-suited for this application. Our approach was empirically evaluated using a set of 31 points measured in the wind tunnel on a 3D printed model in 1:300 scale of the real architectural design of a concert hall in Ostrava. The results of this evaluation demonstrate the effectiveness of our neural network method in estimating wind pressures on complex freeform facades.

title	A First Step Towards an Intelligent Integrated Design System in the Building Field
source	computer Integrated Future, CIB W78 Seminar. September, 1991. Unnumbered pages : ill. includes bibliography
summary	This article presents the work the Knowledge Base Group is achieving towards the integration of Artificial Intelligence based facilities in the Building design process. After an overview of the current state of the integrated design process, the context and the technical guidelines to realize computer integrated software in the building design field is described. Then some tools are presented to model the knowledge (the HBDS method) and to implement such model in our Mips home-made knowledge modeling software platform (including object-oriented database management facilities, expert system reasoning facilities, hypertext edition facilities, 3D-design and 3D-view modules...). Finally the authors describe the Quakes application devoted to assess detached house anti-seismic capabilities during the design process. A deep conceptual model considers all the semantic entities (columns, resistant panels, openings, ...) involved in the anti-seismic expertise. Using both this conceptual model description of a detached house and the 3D design tool, they input the project. Then the seismic expertise is driven in a divide and conquer approach and records the alleged configuration recognized automatically linked to the corresponding section of the building regulation

title	Dynamic Information System for Modelling of Design Processes
source	Computer Integrated Future, CIB W78 Seminar. september, 1991
summary	Unnumbered : ill. DINAMO is a Dynamic Information System for Modelling of Design Processes. It is intended for use along with product models, data management systems and existing applications. In DINAMO a programming user can define processes. These processes are represented by graphs. The graphs are characterized by nodes and relations between nodes. Each node in a graph represents a task, and each relation can be restricted to conditions. So the way in which a process is actually being performed, that is, the actual path to be evaluated through the graph, can depend on certain conditions. Processes and functions (=software modules) are available to the user as tasks. A consuming user can activate tasks; the DINAMO system regulates the dispatch of the tasks, conform the process and function definitions. Tasks are collected on sheets; sheets are collected in a task box. A task box can be regarded as a certain environment, determined by the programming user. A consuming user can choose between the environments which are available at that moment. With the DINAMO system software and process definitions can be re-used in a simple way

source	Computer Aided Architectural Design Futures: Education, Research, Applications [CAAD Futures ‘91 Conference Proceedings / ISBN 3-528-08821-4] Zürich (Switzerland), July 1991, pp. 225-244
summary	An approach is presented for defining the information needed or used in a design task, based on data modeling techniques. Called EDM, it allows representation of the information complexity imposed both from the performances or technologies involved as well as imposed criteria, such as aesthetic intentions. Here, EDM is applied to the design of chairs, a design domain with highly diverse technologies and information structures. The relation is shown between the information considered and the class of designs possible. Also shown is the complexity of different design structures and the implication of information structures for conventional and creative design.

title	THE FULL-SCALE METHOD AS A TOOL FOR PARTICIPATION
source	Proceedings of the 3rd European Full-Scale Modelling Conference / ISBN 91-7740044-5 / Lund (Sweden) 13-16 September 1990, pp. 23-30
summary	In Lund the full-scale laboratory is mainly used as a tool for citizen or user participation. Our intention is to develop the full-scale method further for this purpose. For several years now, we have carried through projects together with different users - mainly people from various types of working-places but recently also with dwellers. Most of our work has been financed by our clients, i.e. private enterprises, trade unions, county councils or municipalities, but since this summer we also receive support from the Swedish Council for Building Research. We have worked with many types of environments and their specific problems, but thanks to the research money we will now have an opportunity to develop our method in a more conscious manner. The purpose of our research is to increase the awareness of the different mechanisms involved in the participant/user process. We want to improve and refine our method and evaluate its advantages and disadvantages compared to other media for spatial communication. In our research program we will now present some criteria that have developed from our previous experiences and which we find essential to our future work.

source	The Computer Integrated Future, CIB W78 Seminar. september, 1991. Unnumbered. includes bibliography
summary	The appreciation of the performance and the costs of a building should be carried out over the entire life of the building. The usual life cycle cost approach has to be extended to the external costs. Different models of the building-energy-environment system are proposed. The building description is based on a basic physical process model which is linked to the construction operations and cost elements used by quantity surveyors. The necessities for new data structures allowing different views of the data are discussed

summary	This paper presents a stratified approach to the integration of low cost modeling software (such as AutoCAD) with advanced workstation based rendering systems (such as Wavefront and the Silicon Graphics radiosity renderer). Powerful extensions to the basic modeling system are introduced which greatly reduce the required design effort, while significantly increasing the efficiency of the rendering software.

title	Modeling the structure of the flow experience
source	INFORMS Marketing Science and the Internet Mini-Conference, MIT
summary	The flow construct (Csikszentmihalyi 1977) has recently been proposed by Hoffman and Novak (1996) as essential to understanding consumer navigation behavior in online environments such as the World Wide Web. Previous researchers (e.g. Csikszentmihalyi 1990; Ghani, Supnick and Rooney 1991; Trevino and Webster 1992; Webster, Trevino and Ryan 1993) have noted that flow is a useful construct for describing more general human-computer interactions. Hoffman and Novak define flow as the state occurring during network navigation which is: 1) characterized by a seamless sequence of responses facilitated by machine interactivity, 2) intrinsically enjoyable, 3) accompanied by a loss of self-consciousness, and 4) selfreinforcing." To experience flow while engaged in an activity, consumers must perceive a balance between their skills and the challenges of the activity, and both their skills and challenges must be above a critical threshold. Hoffman and Novak (1996) propose that flow has a number of positive consequences from a marketing perspective, including increased consumer learning, exploratory behavior, and positive affect."

title	EVALUATION OF THE OSLD HOUSING SYSTEM
source	Full-Scale Modeling in the Age of Virtual Reality [6th EFA-Conference Proceedings]
summary	In the production of low-income housing, one of the factors that most affects the low cost of each unit is its mass production. When it comes to building a proposed design it must have been sufficiently studied and evaluated. When designing low-income housing it is convenient to exhaust all the possibilities of simulation in order to produce a prototype that, once built, has reduced the risk of errors. Simulations allow to improve the prototype before proceeding to build it. The Real Scale Model (RSM) has proved to be a better simulation tool than computer generated models or 1:10 scale models. It allows to reproduce and evaluate perceptual experiences as well as being user friendly because most of the spatial variables can be represented. This research is another example of the use and effectiveness of the RSM in the field of design and architectural research. A Real Scale Model of the basic unit was built by the students of the course Spatial Design Ability dictated by the LEE. The model was first evaluated empty and then a furnishing solution was proposed, built and evaluated. These evaluations were done by another group of students of the Faculty of Architecture and Planning using the Psychological Impressions Measuring Test (IMIP) developed by Luis La Scalea (1991). This test was designed to measure people’s psychological impressions produced by a space, and consists of a semantic differential structured by eleven pairs of opposing adjectives set on a scale of seven levels. The results of this first evaluation were analysed used to modify the prototype which was evaluated again in order to produce a final layout.

source	Computer Aided Architectural Design Futures: Education, Research, Applications [CAAD Futures ‘91 Conference Proceedings / ISBN 3-528-08821-4] Zürich (Switzerland), July 1991, pp. 203-224
summary	PLASM (Programming LAnguage for Solid Modeling) is a prototype, high level, user oriented, functional design language currently being developed at the University of Rome "La Sapienza". A PLASM "program" is the symbolic definition of a complex of variational polyhedra depending on some unbound variable, and therefore allows for the description of a whole set of geometric solutions to a design problem. In our view the language should be used, possibly with the assistance of a graphical user interface, both in the first steps of the design process as well in the detailed design. In the paper the guide-lines are shown for the preliminary definition of the syntax of the language. The paper also contains the definition of some new and very powerful solid operators.

source	The Computer Integrated Future, CIB W78 Seminar. September, 1991. Unnumbered : ill. includes bibliography
summary	Improved models and methods for building representation are needed for more effective support of design integrity checking and control. A 'generic' object-oriented approach to product modelling allows multiple design representations to be described as different views of a common, gradually evolving building product model. The product model provides the capability to generate, in successive design iterations, a coherent description of the form, structure and dimensions of the building and its assemblies and components. Associated technological and administrative data can be included in or associated with the product description

title	Interaction with Constraints in 3D Modeling
source	Proceedings of ACM/SIGGRAPH Symposium on Solid Modeling and CADCAM Applications, Austin, TX
summary	The purpose of our research is to simplify and improve the effectiveness of the interactive definition of geometric objects in computer aided geometric modeling. To achieve this goal, two ways of defining geometric objects are combined and interfaced 1) the definition of objects by graphical interaction and 2) the specification of objects by geometric constraints. To demonstrate the practicability of the proposed approach, a geometric modeling system was implemented. In this system, interactive modeling operations automatically generate constraints to maintain the properties intended by their invocatio~ and constraints, in turn, determine the degrees of freedom for further int eractive mouse-controlled modeling operations. A symbolic geometric constraint solver is employed for solvings ystems of constraints. Group hierarchies are utilized for representing dependencies and for locfllzing systems of constraints.

source	Reality and Virtual Reality [ACADIA Conference Proceedings / ISBN 1-880250-00-4] Los Angeles (California - USA) October 1991, pp. 193-209
summary	Architectural design knowledge which may take the form of constraints and how it can be incorporated into the solid modeling process is explored and discussed. This theoretical exploration leads to an illustration of a Rinctional general purpose three-dimensional solid modeler which utilizes design knowledge as constraints upon the interactive solid modeling process. From this illustration, it is shown that the incorporation of constraints into ComputerAided Architectural Design can effectively assist in the early stages of the design process. A prototypical application is presented which provides an example in which the definition and implementation of specific design knowledge constrains or characterizes the generative and interactive behavior of user definable threedimensional entities. The basis of this work lies in the ability to create a design space, or building envelope, and to allow the interactive modeling of conceptual elements within, and constrained to, that design space, including the realistic interaction between the entities themselves.

title	Modelling Multiple Views on Buildings
source	The Computer Integrated Future, CIB W78 Seminar. September, 1991. Unnumbered : ill. includes a short bibliography
summary	The building practice is characterized by its loose organization of the different participants, each of whom performs a specific role in a building project and has a specific view on the building project data. When modelling building information it is useful to base the structure of a building model on these views. This can be done by the use of aspect models. This paper presents an approach in which aspect models are used to store view-specific information. The approach is illustrated with an outline of a building reference model. The building reference model consists of a general kernel and view-dependent aspect models. This model is first worked out for one decomposition level, the space unit level. After that the model is extended with other decomposition levels

summary	The introduction of physically-based description and simulation methods to issues of building performance (i.e., acoustic, visual, and air quality; thermal comfort, cost, and long-term system integrity) began in the early 1960s as one of the first examples of computer-aided design in architecture. Since that time, the development of commercially-available computer-aided design systems has largely been oriented towards the visualization and representation of the geometry of buildings, while the development of building performance applications has been concerned with approaches to mathematical and physics-based modeling for predictive purposes.

title	A Framework for Evolutionary Information Model Development
source	The Computer Integrated Future, CIB W78 Seminar. September, 1991. Unnumbered :ill. includes bibliography
summary	Large scale information modelling projects, like the development of ISO/STEP, require a modelling approach that does not develop a new model from scratch, but rather base it on a more generic model which, in turn, is based on an even more abstract model, etc. The resulting structure shows a layered framework. On top of which can be found the most generic concepts and downward the more specific concepts with increased semantics. The benefits of such a model development approach are improvements in: version management, object orientated modelling, concurrent model development, controlled change, standardized interfaces, conformance testing etc. This paper describes an environment which supports the development of a new model out of one or more generic parent models. The generation process consists of two steps. In the first step entities of the parent models can be instanciated while constraining the inherited behavior and introducing new behavior. In fact this process is identical with instanciating run time objects from class templates in the object oriented paradigm. However, in the authors' development environment an important (inherited) property of each entity is self-reproduction. In the second step, therefore, each instance is forced to represent its run time state into some kind of information modelling language specification. Appropriate measures are taken to guarantee that the resulting model will conform the behavior of its parent model(s). The paper demonstrates this approach in a multi-layered example currently being implemented and explores several implementation issues

source	FUTURE CITIES [28th eCAADe Conference Proceedings / ISBN 978-0-9541183-9-6] ETH Zurich (Switzerland) 15-18 September 2010, pp.815-823
summary	Due to improving technology and global competition today sky is the only limit for high towers of metropolitan areas. The increase in number of high rise has been ruining the silhouette of cities all over the world like Istanbul, whose identity and image have also been destroyed by skyscrapers dominating the seven slopes on which it was once built. The urbanization in Istanbul has somehow become homogenous and destructive over the topography. Despite of raising debates on the critical issue now and then, no analytical approach has ever been introduced. The research therefore, aims to analyze the change of Bosphorus silhouette caused by the emergence of high rise blocks in Zincirlikuyu-Maslak route since it was defined as a Central Business District and a high rise development area by Bosphorus Conservation Law in 1991. ArcGIS Desktop software and its analyst extensions are used for mapping, analyzing and evaluating the urban development within years. The application is considered to be the initial step for a decision support system which will assist in assigning ground for high rise buildings in Istanbul.
