summary This paper presents a method for representing complex models with various levels of detail. It is based on a geometric simplification algorithm and is applied to a scene described by a rooted-tree structure. In order to control the restuting image quality and the computation time, we propose two algorithms which allow to choose one representation of the scene.

title Interface Design for Building Performance Modeling: Information Representation and Transformation
source Sixth International Conference on Computer-Aided Architectural Design Futures [ISBN 9971-62-423-0] Singapore, 24-26 September 1995, pp. 141-152
summary Building design is an integrative endeavor encompassing a multi-variate agenda that deals simultaneously with issues of architectural elements, their attributes (geometry, material properties, etc.), contextual variables (e.g., the uncontrollable external environmental conditions), and building performance variables (e.g., the potentially controllable indoor environment in terms of thermal, acoustical, visual requirements). Ultimately, an important objective of design is to create built environments that are responsive to occupant needs and building performance requirements. This paper will suggest a framework for developing appropriate representations of the complexities involved in building performance simulation. This is based on studies of the communication requirements pertaining to the informational content involved in the design process, and the interfacial relationships between various analytical components as well as between the user and the system. The applicability and effectiveness of this theoretical framework is demonstrated using the example of a fully operational hygro-thermal analysis program (META-4) developed by the authors.

summary Charlas Magistrales 2There never has been such an exciting moment in time in the extraordinary 30 year history of our subject area, as NOW,when the philosophical theoretical and practical issues of virtuality are taking centre stage.The PastThere have, of course, been other defining moments during these exciting 30 years:• the first algorithms for generating building layouts (circa 1965).• the first use of Computer graphics for building appraisal (circa 1966).• the first integrated package for building performance appraisal (circa 1972).• the first computer generated perspective drawings (circa 1973).• the first robust drafting systems (circa 1975).• the first dynamic energy models (circa 1982).• the first photorealistic colour imaging (circa 1986).• the first animations (circa 1988)• the first multimedia systems (circa 1995), and• the first convincing demonstrations of virtual reality (circa 1996).Whereas the CAAD community has been hugely inventive in the development of ICT applications to building design, it hasbeen woefully remiss in its attempts to evaluate the contribution of those developments to the quality of the built environmentor to the efficiency of the design process. In the absence of any real evidence, one can only conjecture regarding the realbenefits which fall, it is suggested, under the following headings:• Verisimilitude: The extraordinary quality of still and animated images of the formal qualities of the interiors and exteriorsof individual buildings and of whole neighborhoods must surely give great comfort to practitioners and their clients thatwhat is intended, formally, is what will be delivered, i.e. WYSIWYG - what you see is what you get.• Sustainability: The power of «first-principle» models of the dynamic energetic behaviour of buildings in response tochanging diurnal and seasonal conditions has the potential to save millions of dollars and dramatically to reduce thedamaging environmental pollution created by badly designed and managed buildings.• Productivity: CAD is now a multi-billion dollar business which offers design decision support systems which operate,effectively, across continents, time-zones, professions and companies.• Communication: Multi-media technology - cheap to deliver but high in value - is changing the way in which we canexplain and understand the past and, envisage and anticipate the future; virtual past and virtual future!MacromyopiaThe late John Lansdown offered the view, in his wonderfully prophetic way, that ...”the future will be just like the past, onlymore so...”So what can we expect the extraordinary trajectory of our subject area to be?To have any chance of being accurate we have to have an understanding of the phenomenon of macromyopia: thephenomenon exhibitted by society of greatly exaggerating the immediate short-term impact of new technologies (particularlythe information technologies) but, more importantly, seriously underestimating their sustained long-term impacts - socially,economically and intellectually . Examples of flawed predictions regarding the the future application of information technologiesinclude:• The British Government in 1880 declined to support the idea of a national telephonic system, backed by the argumentthat there were sufficient small boys in the countryside to run with messages.• Alexander Bell was modest enough to say that: «I am not boasting or exaggerating but I believe, one day, there will bea telephone in every American city».• Tom Watson, in 1943 said: «I think there is a world market for about 5 computers».• In 1977, Ken Olssop of Digital said: «There is no reason for any individuals to have a computer in their home».The FutureJust as the ascent of woman/man-kind can be attributed to her/his capacity to discover amplifiers of the modest humancapability, so we shall discover how best to exploit our most important amplifier - that of the intellect. The more we know themore we can figure; the more we can figure the more we understand; the more we understand the more we can appraise;the more we can appraise the more we can decide; the more we can decide the more we can act; the more we can act themore we can shape; and the more we can shape, the better the chance that we can leave for future generations a trulysustainable built environment which is fit-for-purpose, cost-beneficial, environmentally friendly and culturally significactCentral to this aspiration will be our understanding of the relationship between real and virtual worlds and how to moveeffortlessly between them. We need to be able to design, from within the virtual world, environments which may be real ormay remain virtual or, perhaps, be part real and part virtual.What is certain is that the next 30 years will be every bit as exciting and challenging as the first 30 years.

title AN EVOLUTIONARY ARCHITECTURE
source London: Architectural Association
summary In "An Evolutionary Architecture", John Frazer presents an overview of his work for the past 30 years. Attempting to develop a theoretical basis for architecture using analogies with nature's processes of evolution and morphogenesis. Frazer's vision of the future of architecture is to construct organic buildings. Thermodynamically open systems which are more environmentally aware and sustainable physically, sociologically and economically. The range of topics which Frazer discusses is a good illustration of the breadth and depth of the evolutionary design problem. Environmental Modelling One of the first topics dealt with is the importance of environmental modelling within the design process. Frazer shows how environmental modelling is often misused or misinterpreted by architects with particular reference to solar modelling. From the discussion given it would seem that simplifications of the environmental models is the prime culprit resulting in misinterpretation and misuse. The simplifications are understandable given the amount of information needed for accurate modelling. By simplifying the model of the environmental conditions the architect is able to make informed judgments within reasonable amounts of time and effort. Unfortunately the simplications result in errors which compound and cause the resulting structures to fall short of their anticipated performance. Frazer obviously believes that the computer can be a great aid in the harnessing of environmental modelling data, providing that the same simplifying assumptions are not made and that better models and interfaces are possible. Physical Modelling Physical modelling has played an important role in Frazer's research. Leading to the construction of several novel machine readable interactive models, ranging from lego-like building blocks to beermat cellular automata and wall partitioning systems. Ultimately this line of research has led to the Universal Constructor and the Universal Interactor. The Universal Constructor The Universal Constructor features on the cover of the book. It consists of a base plug-board, called the "landscape", on top of which "smart" blocks, or cells, can be stacked vertically. The cells are individually identified and can communicate with neighbours above and below. Cells communicate with users through a bank of LEDs displaying the current state of the cell. The whole structure is machine readable and so can be interpreted by a computer. The computer can interpret the states of the cells as either colour or geometrical transformations allowing a wide range of possible interpretations. The user interacts with the computer display through direct manipulation of the cells. The computer can communicate and even direct the actions of the user through feedback with the cells to display various states. The direct manipulation of the cells encourages experimentation by the user and demonstrates basic concepts of the system. The Universal Interactor The Universal Interactor is a whole series of experimental projects investigating novel input and output devices. All of the devices speak a common binary language and so can communicate through a mediating central hub. The result is that input, from say a body-suit, can be used to drive the out of a sound system or vice versa. The Universal Interactor opens up many possibilities for expression when using a CAD system that may at first seem very strange.However, some of these feedback systems may prove superior in the hands of skilled technicians than more standard devices. Imagine how a musician might be able to devise structures by playing melodies which express the character. Of course the interpretation of input in this form poses a difficult problem which will take a great deal of research to achieve. The Universal Interactor has been used to provide environmental feedback to affect the development of evolving genetic codes. The feedback given by the Universal Interactor has been used to guide selection of individuals from a population. Adaptive Computing Frazer completes his introduction to the range of tools used in his research by giving a brief tour of adaptive computing techniques. Covering topics including cellular automata, genetic algorithms, classifier systems and artificial evolution. Cellular Automata As previously mentioned Frazer has done some work using cellular automata in both physical and simulated environments. Frazer discusses how surprisingly complex behaviour can result from the simple local rules executed by cellular automata. Cellular automata are also capable of computation, in fact able to perform any computation possible by a finite state machine. Note that this does not mean that cellular automata are capable of any general computation as this would require the construction of a Turing machine which is beyond the capabilities of a finite state machine. Genetic Algorithms Genetic algorithms were first presented by Holland and since have become a important tool for many researchers in various areas.Originally developed for problem-solving and optimization problems with clearly stated criteria and goals. Frazer fails to mention one of the most important differences between genetic algorithms and other adaptive problem-solving techniques, ie. neural networks. Genetic algorithms have the advantage that criteria can be clearly stated and controlled within the fitness function. The learning by example which neural networks rely upon does not afford this level of control over what is to be learned. Classifier Systems Holland went on to develop genetic algorithms into classifier systems. Classifier systems are more focussed upon the problem of learning appropriate responses to stimuli, than searching for solutions to problems. Classifier systems receive information from the environment and respond according to rules, or classifiers. Successful classifiers are rewarded, creating a reinforcement learning environment. Obviously, the mapping between classifier systems and the cybernetic view of organisms sensing, processing and responding to environmental stimuli is strong. It would seem that a central process similar to a classifier system would be appropriate at the core of an organic building. Learning appropriate responses to environmental conditions over time. Artificial Evolution Artificial evolution traces it's roots back to the Biomorph program which was described by Dawkins in his book "The Blind Watchmaker". Essentially, artificial evolution requires that a user supplements the standard fitness function in genetic algorithms to guide evolution. The user may provide selection pressures which are unquantifiable in a stated problem and thus provide a means for dealing ill-defined criteria. Frazer notes that solving problems with ill-defined criteria using artificial evolution seriously limits the scope of problems that can be tackled. The reliance upon user interaction in artificial evolution reduces the practical size of populations and the duration of evolutionary runs. Coding Schemes Frazer goes on to discuss the encoding of architectural designs and their subsequent evolution. Introducing two major systems, the Reptile system and the Universal State Space Modeller. Blueprint vs. Recipe Frazer points out the inadequacies of using standard "blueprint" design techniques in developing organic structures. Using a "recipe" to describe the process of constructing a building is presented as an alternative. Recipes for construction are discussed with reference to the analogous process description given by DNA to construct an organism. The Reptile System The Reptile System is an ingenious construction set capable of producing a wide range of structures using just two simple components. Frazer saw the advantages of this system for rule-based and evolutionary systems in the compactness of structure descriptions. Compactness was essential for the early computational work when computer memory and storage space was scarce. However, compact representations such as those described form very rugged fitness landscapes which are not well suited to evolutionary search techniques. Structures are created from an initial "seed" or minimal construction, for example a compact spherical structure. The seed is then manipulated using a series of processes or transformations, for example stretching, shearing or bending. The structure would grow according to the transformations applied to it. Obviously, the transformations could be a predetermined sequence of actions which would always yield the same final structure given the same initial seed. Alternatively, the series of transformations applied could be environmentally sensitive resulting in forms which were also sensitive to their location. The idea of taking a geometrical form as a seed and transforming it using a series of processes to create complex structures is similar in many ways to the early work of Latham creating large morphological charts. Latham went on to develop his ideas into the "Mutator" system which he used to create organic artworks. Generalising the Reptile System Frazer has proposed a generalised version of the Reptile System to tackle more realistic building problems. Generating the seed or minimal configuration from design requirements automatically. From this starting point (or set of starting points) solutions could be evolved using artificial evolution. Quantifiable and specific aspects of the design brief define the formal criteria which are used as a standard fitness function. Non-quantifiable criteria, including aesthetic judgments, are evaluated by the user. The proposed system would be able to learn successful strategies for satisfying both formal and user criteria. In doing so the system would become a personalised tool of the designer. A personal assistant which would be able to anticipate aesthetic judgements and other criteria by employing previously successful strategies. Ultimately, this is a similar concept to Negroponte's "Architecture Machine" which he proposed would be computer system so personalised so as to be almost unusable by other people. The Universal State Space Modeller The Universal State Space Modeller is the basis of Frazer's current work. It is a system which can be used to model any structure, hence the universal claim in it's title. The datastructure underlying the modeller is a state space of scaleless logical points, called motes. Motes are arranged in a close-packing sphere arrangement, which makes each one equidistant from it's twelve neighbours. Any point can be broken down into a self-similar tetrahedral structure of logical points. Giving the state space a fractal nature which allows modelling at many different levels at once. Each mote can be thought of as analogous to a cell in a biological organism. Every mote carries a copy of the architectural genetic code in the same way that each cell within a organism carries a copy of it's DNA. The genetic code of a mote is stored as a sequence of binary "morons" which are grouped together into spatial configurations which are interpreted as the state of the mote. The developmental process begins with a seed. The seed develops through cellular duplication according to the rules of the genetic code. In the beginning the seed develops mainly in response to the internal genetic code, but as the development progresses the environment plays a greater role. Cells communicate by passing messages to their immediate twelve neighbours. However, it can send messages directed at remote cells, without knowledge of it's spatial relationship. During the development cells take on specialised functions, including environmental sensors or producers of raw materials. The resulting system is process driven, without presupposing the existence of a construction set to use. The datastructure can be interpreted in many ways to derive various phenotypes. The resulting structure is a by-product of the cellular activity during development and in response to the environment. As such the resulting structures have much in common with living organisms which are also the emergent result or by-product of local cellular activity. Primordial Architectural Soups To conclude, Frazer presents some of the most recent work done, evolving fundamental structures using limited raw materials, an initial seed and massive feedback. Frazer proposes to go further and do away with the need for initial seed and start with a primordial soup of basic architectural concepts. The research is attempting to evolve the starting conditions and evolutionary processes without any preconditions. Is there enough time to evolve a complex system from the basic building blocks which Frazer proposes? The computational complexity of the task being embarked upon is not discussed. There is an implicit assumption that the "superb tactics" of natural selection are enough to cut through the complexity of the task. However, Kauffman has shown how self-organisation plays a major role in the early development of replicating systems which we may call alive. Natural selection requires a solid basis upon which it can act. Is the primordial soup which Frazer proposes of the correct constitution to support self-organisation? Kauffman suggests that one of the most important attributes of a primordial soup to be capable of self-organisation is the need for a complex network of catalysts and the controlling mechanisms to stop the reactions from going supracritical. Can such a network be provided of primitive architectural concepts? What does it mean to have a catalyst in this domain? Conclusion Frazer shows some interesting work both in the areas of evolutionary design and self-organising systems. It is obvious from his work that he sympathizes with the opinions put forward by Kauffman that the order found in living organisms comes from both external evolutionary pressure and internal self-organisation. His final remarks underly this by paraphrasing the words of Kauffman, that life is always to found on the edge of chaos. By the "edge of chaos" Kauffman is referring to the area within the ordered regime of a system close to the "phase transition" to chaotic behaviour. Unfortunately, Frazer does not demonstrate that the systems he has presented have the necessary qualities to derive useful order at the edge of chaos. He does not demonstrate, as Kauffman does repeatedly, that there exists a "phase transition" between ordered and chaotic regimes of his systems. He also does not make any studies of the relationship of useful forms generated by his work to phase transition regions of his systems should they exist. If we are to find an organic architecture, in more than name alone, it is surely to reside close to the phase transition of the construction system of which is it built. Only there, if we are to believe Kauffman, are we to find useful order together with environmentally sensitive and thermodynamically open systems which can approach the utility of living organisms.

title Evolving building blocks for design using genetic engineering: A formal approach
source J.S. Gero and F. Sudweeks (eds), Advances in Formal Design Methods for CAD , IFIP-University of Sydney, Sydney, pp. 29-48
summary This paper presents a formal approach to the evolution of a representation for use in a design process. The approach adopted is based on concepts associated with genetic engineering. An initial set of genes representing elementary building blocks is evolved into a set of complex genes representing targeted building blocks. These targeted building blocks have been evolved because they are more likely to produce designs which exhibit desired characteristics than the commencing elementary building blocks. The targeted building blocks can then be used in a design process. The paper presents a formal evolutionary model of design representations based on genetic algorithms and uses pattern recognition techniques to execute aspects of the genetic engineering. The paper describes how the state space of possible designs changes over time and illustrates the model with an example from the domain of two-dimensional layouts. It concludes with a discussion of style in design.

title STAR methodology-based learning about construction accidents and their prevention
source Automation in Construction 4 (1) (1995) pp. 75-85
summary This paper presents the results of a feasibility study concerning the application of STAR-methodology-basedmachine learning to construction accidents and their prevention. A ten-stage knowledge acquisition process is presented and its individual stages described. Knowledge about construction accidents was acquired using a collection of 225 examples, based on actual accidents records. Inductive learning with a system based on the STAR-methodology was employed. This system was used in both the generalization and specialization modes of operation. The decision rules obtained are complex, but their interpretation is clear and they seem to be consistent with the present understanding of causal relationships between accident results and various factors affecting them. Also, the rules were verified using average overall and omission empirical error rates, which were calculated as average for three randomly determined sequences of examples. These error rates were calculated for all seven steps in the machine learning process, and were used to construct learning curves for both error rates. The relationships between error rates and the number of examples used for learning are analyzed, and coefficients of linear regression given and discussed. The 225 examples used were found to be grossly insufficient to produce reliable knowledge about accidents and therefore a large study is postulated which would involve the collection of a larger number of construction accident records. In general, our study demonstrated the feasibility of machine learning in acquiring knowledge about construction accidents.

title Designing Architectural Experiences: Using Computers to Construct Temporal 3D Narratives
doi https://doi.org/10.52842/conf.acadia.1995.139
source Computing in Design - Enabling, Capturing and Sharing Ideas [ACADIA Conference Proceedings / ISBN 1-880250-04-7] University of Washington (Seattle, Washington / USA) October 19-22, 1995, pp. 139-149
summary Computers are launching us into a representational revolution that fundamentally challenges the way we have hitherto conceived and practiced architecture. This paper will explore one of its fronts: the simulation of architectural experiences. Today's off-the-shelf softwares (e.g. 3D modeling, animations, multimedia) allow us for first time in history to depict and thus approach architectural design and criticism truly experientially. What is so appealing about this is the possibility of shifting our attention from the object to the experience of the object and in so doing reconceptualizing architectural design as the design of architectural experiences. Carrying forward such a phenomenological proposition requires us to know (1) how to work with non-traditional and 'quasi-immersive' (or subject-centered) representational systems, and (2) how to construct temporal assemblages of experiential events that unfold not unlike 'architectural stories'. As our discipline lacks enough knowledge on this area, importing models from other fields appears as an appropriate starting point. In this sense, the narrative arts (especially those involved with the temporal representation of audio-visual narratives) offer us the best insights. For example, principles of cinema and storytelling give us an excellent guidance for designing architectural experiences that have a structuring theme (parti), a plot (order), unfolding episodes (rhythm), and special events (details). Approaching architecture as a temporal 3D narrative does transform the design process and, consequently, its results. For instance, (1) phenomenological issues enter the decision making process in an equal footing to functional, technological, or compositional considerations; (2) orthographic representations become secondary sources of information, mostly used for later accurate dimensioning or geometrization; (3) multi-sensory qualities beyond sight are seriously considered (particularly sound, texture, and kinesthetic); etc.

The first is the analysis of the design group coordination and communication. The second introduces the concept of Coordinative Virtual Space: this is a common multi-dimensional space where the group members share design information. The third presents the implementation: each member can connect to the shared space through the computer network and display several projections of the design information space.

summary This paper proposes a logic-based framework for representing and manipulating knowledge during Computer-Aided Architectural Design. The framework incorporates a meta-level architecture to represent declarative design knowledge and strategic knowledge used by the designer. It consists of an object layer, a design requirements layer and strategies for navigating through the design space. An extended first-order logic is described which has been used to represent some examples of architectural knowledge. This computational model is being implemented in KAUS (Knowledge Acquisition and Utilisation System), a general purpose knowledge-based system, founded in Multi-Layered Logic.

summary In the few short years since the emergence of multimedia programming tools this activity has moved from the periphery of the Information Technologies to the mainstream of computing applications. This is due not only to the progressive development in hardware and software technologies but also to the escalating set of desires of authors and users of multimedia products. Perhaps the most interesting theme within this strand of development is in the progression of the capabilities of the scripting and programming capabilities now on offer. The purpose of this paper is to trace the development of this aspect and speculate on the future of multimedia authoring tools as a new generation programming environment where the distinction between multimedia and CAD becomes less well defined.

summary Contemporary multimedia research address the possibilities and consequences of integrating various techniques to produce single user based applications (singularity). There is a need for utilising current multimedia techniques; to explore the potential of multi-models (theoretically) to generate modelling information that could be shared simultaneously. The problems are confined to understanding and managing the issues that influence the so-called ´target and product models´. This paper introduces and elaborates on such problems. It provides a theoretical and another practical framework, the 3D-CAD Modelling Paradigm, based upon completed results of modelling. There is a suggested evidence that there might be advantages in standardising the process of modelling and knowledge representation. The paper stresses that the composition of a model should differ from another to reflect its unique characteristics (singularity). Though, it is essential that such models should conform and respond to the well defined and shared criteria (pluralism).

summary This research focuses on combining the rich representations of computer-aided design systems with current collaboration technologies to support distributed design processes. Our emphasis is not on concurrent multi-user access to integrated databases, but rather on shared protocols of interaction that are independent of implementation and storage schemes. We have developed a prototype for a Synchronous Collaborative Design System (SYCODE) that enables geographically dispersed designers to share common representations even when using different hardware platforms. The limitations of the existing network infrastructure have compelled its to devise a meaningful and parsimonious representation scheme and to semantically define pending and confirmed actions.

title Design Tools Integration in an Integrated Design Environment
doi https://doi.org/10.52842/conf.acadia.1995.075
source Computing in Design - Enabling, Capturing and Sharing Ideas [ACADIA Conference Proceedings / ISBN 1-880250-04-7] University of Washington (Seattle, Washington / USA) October 19-22, 1995, pp. 75-95
summary The design problem has a multi-disciplinary nature and the design itself evolves as solutions are attempted by the designer. To support inter-disciplinary communication of design concepts and decisions, the integration of relevant CAAD tools is essential. Based upon a large set of design criteria and all corresponding knowledge, with the help of computer aided design tools, the result could be highly effective and novel. The integration of CAAD tools should be performed on the basis of generating better solutions by enabling designers to manipulate and appraise various solutions quickly and with a minimum of effort. The proposed system provides the foundations for a seamless and continuous working environment for architects and building engineers through a data modelling module, an integrated data management framework and various design tools. In the environment, stand-alone design tools can be plugged-in in order to access information stored in central databases. The suggested data modelling module helps integrated CAAD systems represent and exchange domain dependent design information at a semantic level, such as exchanging components and features of a building rather than graphical primitives. The suggested data management framework supports the straight-forward mechanisms for controlling the data representation through the inter-connected modules and design tools.

title Communication of Ideas in Architecture Versus Computer Techniques
source CAD Space [Proceedings of the III International Conference Computer in Architectural Design] Bialystock 27-29 April 1995, pp. 171-180
summary Computer as a tool in architects' work is an obvious thing for near all of us. Recent two - three years have shown that probably the most revolutionary feature of computers is their immense possibility of usage in today's communication techniques, the continuous flow of information. This fact makes us to think about computer techniques as an useful tool not only in designing, but also in extensive presenting of ideas - like communication between architects and all the others involved in the designing and building process. Presenting ideas requires prior process of gathering data and storing it in computers' memory. Incredible progress in ways of organizing information leads also to the idea of developing a sketch of a standard of the amount and structure of information gathered to make it an universal set of parameters describing the design - a multi - functional database. The first part (presenting ideas) is more to be used in Poland by now. Architects should appreciate benefits of an impressive presentation and they already started to. The universal database for use by everyone, or rather a file of the project, which presentation is a part of, is rather a theory by now. But exploring it’s potential and a real need to create one - is essential.

title CAAD's Seven Arguable Virtues
source International Journal of Architectural Computing vol. 2 - no. 1
summary In 1995 Maver proposed seven deadly sins for CAAD as the prelude to a critical discussion on the principles, methods and practices of the field. In an attempt to return to this discussion, in this paper these sins are linked to the seven deadly sins and the complementary seven heavenly virtues. The analysis of computational processes into a theoretic, an algorithmic and an implementational framework provides a framework for the positioning of sins and possible or already attained virtues in CAAD.

title On the dynamic control of a hydraulic large range robot for construction applications
source Automation in Construction 4 (1) (1995) pp. 61-73
summary There are various important outdoor applications in the fields of civil engineering, environmental technology or catastrophy management which require the introduction of a large range robot. In collaboration with industrial partners the KfK has developed such Extended Multi joint Robot (EMIR) which is driven by hydraulic actuators. The position control of EMIR is a tough problem due to the extreme nonlinearities of the kinematics and hydraulic actuators as well as the remarkable elasticities of the mechanics and hydraulics. In the first part of this paper a realistic physically transparent model of the robot will be presented. In the second part different suitable control concepts based on the model will be discussed.

source Sixth International Conference on Computer-Aided Architectural Design Futures [ISBN 9971-62-423-0] Singapore, 24-26 September 1995, pp. 181-185
summary The quality of the built environment depends critically on the concept of sustainability and, in particular, on designs which are energy efficient and environmentally friendly. This paper gives an account of the successful application of computer-based simulations of the physical environment made available to architects through an Energy Design Advisory Service and used parametrically within a research project carried out jointly with a design and build company. It goes on to indicate how emerging multi-media technology can be used to provide an explanation, particularly to those who are technically unsophisticated, of the complexity of the way in which design decisions impact upon the energy efficiency and environmental friendliness of buildings.
