title Integrating sustainable building rating systems with building information models
source CAADRIA 2008 [Proceedings of the 13th International Conference on Computer Aided Architectural Design Research in Asia] Chiang Mai (Thailand) 9-12 April 2008, pp. 193-200
summary The transition from conventional to sustainable building depends on a number of factors— technological, environmental, economic and social. From a computer-aided design perspective, the first two are perhaps the most significant. We are working on a project with an emphasis on developing tools, to evaluate environmental consequences for design decision-making. Our current thrust is given to reducing energy usage as well as carbon emissions in buildings.

title Representational Limitations and Improvements in Building Information Modeling
source Architecture in Computro [26th eCAADe Conference Proceedings / ISBN 978-0-9541183-7-2] Antwerpen (Belgium) 17-20 September 2008, pp. 35-42
summary This paper discusses advantages and limitations of different representation types, illustrated with examples from current commercial Building Information Modeling applications. There is still a potential benefit in more thoroughly adapting additional representations to access and manage project data.The paper presents arguments to adapt a hybrid approach, where multiple representations should form a series of interfaces to interact with a building model. Inspiration is derived from software applications not associated with Building Information Modeling.

summary Over the last decade various examples of urban 3D models have been created employing various techniques for data collection and model building. The problems faced are well documented, issues of accuracy, complexity and utility of the models has also been addressed. This paper presents a low tech approach to accurate city modeling focusing on engineering applications, browsing/experiencing applications as well as multi-layering time based analyses, historical info overlaying for use in interactive real time applications (museum exhibitions, research projects for behavioral patterns of users in 3D urban environments, marketing, tourism, etc). The pros and cons of the proposed methodology are analyzed and ways forward suggested.

title Viewing Models in Architecture
source Proceedings of the 8th European Architectural Endoscopy Association Conference
summary If we wish to understand the workings of design interventions, it may be opportune to simulate their effects using specialised techniques, such as Endoscopy or Computer Aided Modes of representation. In such undertakings, the method of study will generally involve the active use of some sort of a model. Models of all sorts are used extensively throughout architectural design, research and education. How such a model is conceived and executed is closely linked to the function it is to serve. This may concern design driven exploration, testing or communication, to name but a few of the options.

summary In education and research at this time there is arguably no longer a need to build a strong case for the power of CAAD to support designers – the evidence is there. The major challenges no longer centre on hardware, software and graphics potential or on skills acquisition and adoption. The research that we will report here reveals that computational complexity and geometrical complexity are emerging as the sharp issues that demand a major review of how we model the large hybrid spaces that we seek to construct in design. Computational relational modeling and scripting may have opened a trove of creative possibilities. But it may delude us into painting ourselves into a corner: infinite variety within a much reduced palette of opportunities.

title Agent-Based System for Modeling User Behavior in Shopping Malls
source Architecture in Computro [26th eCAADe Conference Proceedings / ISBN 978-0-9541183-7-2] Antwerpen (Belgium) 17-20 September 2008, pp. 635-642
summary Agent-based systems are being used as decision support systems for solving architectural design problems. Usually in design phase, user behavior is ignored by the designers. Therefore, after the construction, the users face difficulties in emergency situations and in daily usage. As a result, buildings become insufficient to respond to users’ needs and design goals of the building itself. Before construction, ability of testing the interactions between the building and its users is particularly important to solve the problems in early phases of the design. Hence, to design a building that functions better in certain situations and time loss decreases in the design process. For these reasons, the aim of this study is to develop a model to simulate users in shopping malls.

summary The role of the architect is quite literally one of assembly: synthesizing the various parts of a project into a cohesive whole. It is a difficult job, often requiring the architect to weave many seemingly contradictory concerns into a solution that benefits them all. It is not surprising then, that the many elegant and effective systems found in nature should be inspiring to the architect. Emerging fields like biomimicry and systems dynamics model the patterns of interaction between organisms and their environments in terms of dynamic part to part and part to whole relationships. ¶ Observations of real relationships between organisms and their environments, as they exist in nature, reveal complex feedback loops working across multiple scales. These feedback loops operate by the simultaneous action of two observed phenomena. The first is the classic phenotypic relationship seen when organisms of the same genetic makeup instantiate differently based upon differences in their environment. This is the relationship that was originally proposed by Charles Darwin in his theory of natural selection of 1859. Darwin’s model is unidirectional: the organism adapts to its environment, but not the other way around. It operates at the local scale as individual parts react to the conditions of the whole. (Canguilhem, 1952). ¶ The second phenomenon, which sees its effect at the global scale, is the individual’s role as consumer and producer in the flows of energy and material that surround it. It is the subtle and incremental influence of the organism upon its environment, the results of which are often invisible until they reach a catastrophic threshold, at which point all organisms in the system feel global changes. ; The research presented in this paper addresses the dialectic between organism and environment as each responds reciprocally to the others’ changing state. Such feedback loops act in a non-linear fashion, across nested scales in biological systems. They can be modeled to act that way in a digital design process as well. This research is an exploration into one such model and its application to architecture: the simple communication between organisms as they affect and are affected by their environments through the use of signal chemicals.

title Lazy Panorama Monopoly Table: Take Your City for a Spin
source CAADRIA 2008 [Proceedings of the 13th International Conference on Computer Aided Architectural Design Research in Asia] Chiang Mai (Thailand) 9-12 April 2008, pp. 662-669
summary While conventional information displays are still effective, a lack of integration between descriptive and contextual information means they cannot be used independently of additional external information. New digital systems such as Google Maps are increasing in popularity. Unfortunately these present some limitations in terms of understanding both route and survey information, and in particular navigation and orientation, such as intuitively understanding a plan view no matter which way one is facing, so visitors can quickly and intuitively learn how to get to specific buildings or to specific facilities. Digital systems may also alienate older and non computer literate users; and they display contextual information inside an interface which limits the possible range of interaction methods offered by physical interaction. Our solution was to create a 3D physical model that one could spin, which would in turn display digital panoramas that spun in rotational alignment with the physical city model. Further, the user could place category tokens in intersections of the city model, which would bring up digital panoramas on the screen and highlight facilities linked to the category chosen. Rotating the token would also rotate the digital panorama.

title The design of an interactive scenario-based agent simulator for supporting the early stages of urban design
source CAADRIA 2008 [Proceedings of the 13th International Conference on Computer Aided Architectural Design Research in Asia] Chiang Mai (Thailand) 9-12 April 2008, pp. 42-48
summary Recently, urban planning has largely placed the user at street as the centre of infrastructural design, with significant implications for the perceived attractiveness of user environments. The urban designers faced with the task of designing such spaces, needs a tool that will allow different designs to be compared in terms of their attractiveness as well as their effectiveness. Therefore, this paper applies the selective attention theory and establishes a pedestrian behavior model that embeds the behavior-based rules and attributes of an agent. We call this simulation platform to be an agent-based street simulator (ABSS). Through experiments and verifications on cases of real-life urban streets, the system and its applications, and major findings are reported.

title Interactive parametric modelling: POG a tool the cultural heritage monument 3D reconstruction
source CAADRIA 2008 [Proceedings of the 13th International Conference on Computer Aided Architectural Design Research in Asia] Chiang Mai (Thailand) 9-12 April 2008, pp. 487-493
summary Historic monument and archaeological site 3D reconstruction is nowadays often required for many applications (scientific and architectural studies, virtual visits for a better understanding of the monument, etc). This task is very time-consuming. Automating the modelling of the most common components could ease this 3D work and produce accurate, consistent and re-usable models. Based upon compound rules of architectural elements but also upon various other data sources such as photographs and 3D laser scans, we have conceived and developed an interactive tool for virtual 3D reconstruction of heritage monuments. It allows a quick modelling and accurate adjustments to the measured data. This tool could be a great help for architects and archaeologists. Research first has began with the study of classical architecture, and has gone on with other architectural styles. Architectural elements are described with parametric data, then generated by our tool. Our main application context was the town of Nancy in France where there are lots of classical architecture buildings which allow us to test our tool. It will be further extended to be applied to other architectural styles and will be combined with photogrammetry methods.

summary Based on the importance of human behavior analysis in HCI research, this paper discusses the property of interaction in sending/receiving direction with diverse cases. A unit of contextual bricks was created as research model continuing to discover the possible solution on the problem that how to merge the novel media and technology into our living space invisibly with the exhibition of appropriate information. The prototype of contextual bricks preserved the characteristic of stability with cellular hexagonal structure, and each unit was designed with communicable construction. The people could get the contextual information from other spaces as seeing through the walls. In the future study, the contextual bricks have good applied possibility and developments in each kind of areas.

source Parametricism Vs. Materialism: Evolution of Digital Technologies for Development [8th ASCAAD Conference Proceedings ISBN 978-0-9955691-0-2] London (United Kingdom) 7-8 November 2016, pp. 249-258
summary The term "Parametricism" widespread mainly by Patrick Schumacher (Schumacher, 2008) is worthy of study. Developing the concept of Human Oriented Parametric Architecture, the need of implementing time as the lost parameter in current adaptive design techniques will be discussed. Morphogenetic processes ideas will be discussed through the principle of an adaptable membrane as a case study. A model implementing a unique Arduino[i] on the façade will control its patterns performance through an Artificial Neural Network that will understand the kind of scenario the building is in, activating a Genetic Algorithm that will optimize the insulation performance of the ETFE pillows. The system will work with a global behavior for façade pattern performance and with a local one for each pillow, giving the option of individual sun-shading control. Machine learning implementation will give the façade the possibility to learn from the efficacy of its decisions through time, eliminating the need of a general on-off behavior.

source SIGraDi 2008 - [Proceedings of the 12th Iberoamerican Congress of Digital Graphics] La Habana - Cuba 1-5 December 2008
summary The objective of the present research was to study the use of animation techniques as a tool for the design process. The study started with a literature review about the different possible applications of animation techniques in architectural design. Four main categories of applications were found: (1) space representation and “walk through”, (2) simulation of articulated elements and kinetic structures, (3) visualization and analysis of functional aspects of the buildings, such as circulation and fire escape, and finally (4) the generation of novel shapes. The second part of the research consisted of a design exercise in which animation techniques were used to generate a shape. For this purpose a wind simulator was used in 3DMAX. Next, Paracloud software was used to automatically generate a rib structure that allowed to produce a scale model of the shape with a laser cutter.

title Improved Understanding of Urban Sprawl Using Neural Networks

summary It is widely accepted that the spatial pattern of settlements is a crucial factor affecting quality of life and environmental sustainability, but few recent studies have attempted to examine the phenomenon of sprawl by modelling the process rather than adopting a descriptive approach. The issue was partly addressed by models of land use and transportation which were mainly developed in the UK and US in the 1970s and 1980s, but the major advances were made in the area of modelling transportation, while very little was achieved in the area of spatial and temporal land use. Models of land use and transportation are well-established tools, based on explicit, exogenouslyformulated rules within a theoretical framework. The new approaches of artificial intelligence, and in particular, systems involving parallel processing, (Neural Networks, Cellular Automata and Multi-Agent Systems) defined by the expression “Neurocomputing”, allow problems to be approached in the reverse, bottom-up, direction by discovering rules, relationships and scenarios from a database. In this article we examine the hypothesis that territorial micro-transformations occur according to a local logic, i.e. according to use, accessibility, the presence of services and conditions of centrality, periphericity or isolation of each territorial “cell” relative to its surroundings. The prediction capabilities of different architectures of supervised Neural networks are implemented to the south Metropolitan area of Milan at two different temporal thresholds and discussed. Starting from data on land use in 1980 and 1994 and by subdividing the area into square cells on an orthogonal grid, the model produces a spatial and functional map of urbanisation in 2008. An implementation of the SOM (Self Organizing Map) processing to the Data Base allows the typologies of transformation to be identified, i.e. the classes of area which are transformed in the same way and which give rise to territorial morphologies; this is an interesting by-product of the approach.

title Constraint-Based Design in Participatory Housing Planning
source International Journal of Architectural Computing vol. 6 - no. 1, pp. 97-117
summary We introduce some novel ideas for a constraint-based design strategy to support participatory housing planning processes in Latin America. The following lines intend to open the discussion on the requirements and effect of the computer implementation of a constraint satisfaction approach to solve elementary design problems in architectural practice. The case study applies to the building massing design problem posed by the Chilean urban regulatory framework that addresses single-family affordable houses. Two different implementation criteria are being tested in an ongoing series of trials providing further considerations. One prototype uses MAXON's CINEMA4D XPRESSO® visual scripting environment to set up a semi-automated design environment which allows users to edit one feature-based 3D model of massing alternative at a time. The other prototype uses ILOG's OPL STUDIO® constraint programming environment to achieve fully automated search and 2D visualization of all possible solution alternatives to separate subdomains of the building massing design problem.

title Design Flow and Ideation
source International Journal of Architectural Computing vol. 6 - no. 3, pp. 299-316
summary In the last year, we developed the Hybrid Ideation Space (HIS), an innovative immersive sketching and model-making system that augments analog tools with digital capabilities, for continue and direct reflective conversation with the representation. The system enables designers to sketch and make models all around them in real-time and real scale using a digital tablet (sketches), image capture (physical models) and a spherical projection device (immersion). Teams of industrial design students participated in the study working on the initial stages of the design of a car. This is a comparative study putting side by side the HIS, analog tools and hybrid modeling techniques. We developed the notion of Design Flow to assesses the design ideation process. The students reported being in the state of flow more often in the HIS than with digital or physical modeling.

title Designing (tools (for designing (tools for ...))))
source RMIT University, Melbourne
summary Outcomes of innovative designing are frequently described as enabling us in achieving more desirable futures. How can we design and innovate so as to enable future processes of design and innovation? To investigate this question, this thesis probes the conditions, possibilities and limitations of toolmaking for novelty and knowledge generation, or in other words, it examines designing for designing. The focus of this thesis is on the development of digital design tools that support the reconciliation of conflicting criteria centred on architectural geometry. Of particular interest are the roles of methodological approaches and of biological analogies as guides in toolmaking for design, as well as the possibility of generalising design tools beyond the contexts from which they originate. The presented investigation consists of an applied toolmaking study and a subsequent reflective analysis using second- order cybernetics as a theoretical framework. Observations made during the toolmaking study suggest that biological analogies can, in informal ways, inspire designing, including the designing of design tools. Design tools seem to enable the generation of novelty and knowledge beyond the contexts in and for which they are developed only if their users apply them in ways unanticipated by the toolmaker. Abstract The reflective analysis offers theoretical explanations for these observations based on aspects of second-order cybernetics. These aspects include the modelling of designing as a conversation, different relationships between observers (such as designers) and systems (such as designers engaged in their projects), the distinction between coded and uncoded knowledge, as well as processes underlying the production and the restriction of meaning. Initially aimed at the development of generally applicable, prescriptive digital tools for designing, the presented work results in a personal descriptive model of novelty and knowledge generation in science and design. This shift indicates a perspective change from a positivist to a relativist outlook on designing, which was accomplished over the course of the study. Investigating theory and practice of designing and of science, this study establishes an epistemological model of designing that accommodates and extends a number of theoretical concepts others have previously proposed. According to this model, both design and science generate and encode new knowledge through conversational processes, in which open-minded perception appears to be of greater innovative power than efforts to exercise control. The presented work substantiates and exemplifies radical constructivist theory of knowledge and novelty production, establishes correspondences between systems theory and design research theory and implies that mainstream scientific theories and practices are insufficient to account for and to guide innovation.

In this projects we as architects were asked to show the lifetime-process of an industrial complex (a colliery - now used as industrial museum) over a period of more than one hundred years: the growth of the complex, the demolition of certain buildings, the network between the collieries in the neighbourhood. Google Earth as software platform allows recipients from all over the world to get an insight in four dimensions: the location based context including the time axis. For showing the world under the surface interactive animations or films are included.

summary This paper presents a model of computational analogy-making in designing based on the notion of situated similarity. Situated similarity is the idea that the relationship between two concepts is dependent not only on what the agent knows about those concepts but also on the way the agent is looking at them. Analogy-making is modelled as three interacting processes: formulation, matching and mapping. The model is developed and then its implications for developing situated analogy-making systems in design are discussed.
