title Critical Environmentalism and the Practice of Re-Construction
source Computing in Architecture / Re-Thinking the Discourse: The Second International Conference of the Arab Society for Computer Aided Architectural Design (ASCAAD 2006), 25-27 April 2006, Sharjah, United Arab Emirates
summary This research focuses on the implications and applications of “critical environmentalism” as a quintessential epistemological framework for urban interventions while implementing digital applications that foster collective, round-table approaches to design. Essentially centering the environment (Umwelt) as an encompassing and interconnecting catalyst between multiple disciplines, philosophies, and modes of inquiry and technologies, the framework reciprocally fosters individual and critical identities associated with particular places, belief systems, and their participants as a primary concern. Critical environmentalism promotes a comprehensive, reciprocally unifying epistemological framework that can significantly inform architectural interventions and the tethered use of its technologies in order to foster increased vitality and a certain coinvested attention to the complexities of the greater domain. Grounding the theory in pedagogical practice, this paper documents an approach to urban design and architectural education, implemented as a case-study and design scenario, where divergent perspectives amalgamate into emergent urban configurations, critically rooted in the conditional partialities of place. Digital technologies are incorporated along with analogical methods as tools to integrate multiple perspectives into a single, working plane. Engaging the above framework, the approach fosters a critical (re)construction and on-going, co-vested regeneration of community and the context of place while attempting to dialogically converge multiple urban conditions and modes-of-thought through the co-application of various digital technologies. Critically understanding complex urban situations involves dialogically analyzing, mapping, and modeling a discursive, categorical structure through a common goal and rationale that seeks dialectic synthesis between divergent constructions while forming mutual, catalyzing impetuses between varying facets. In essence, the integration of varying technologies in conjunction, connected to real world scenarios and a guiding epistemic framework cultivates effective cross-pollination of ideas and modes through communicative and participatory interaction. As such it also provides greater ease in crosschecking between a multitude of divergent modes playing upon urban design and community development. Since current digital technologies aid in data collection and the synthesis of information, varying factors can be more easily and collectively identified, analyzed, and then simultaneously used in subsequent design configurations. It inherently fosters the not fully realized potential to collectively overlay or montage complex patterns and thoughts seamlessly and to thus subsequently merge a multitude of corresponding design configurations simultaneously within an ongoing, usable database. As a result, the pedagogical process reveals richly textured sociocultural fabrics and thus produces distinct amplifications in complexity and attentive management of diverse issues, while also generating significant narratives and themes for fostering creative and integrative solutions. As a model for urban community and social development, critical environmentalism is further supported the integrative use of digital technologies as an effective means and management for essential, communicative interchange of knowledge and thus rapprochement between divergent modes-of-thought, promoting critical, productive interaction with others in the (co)constructive processes of our life-space.

title A Constraint-Based Building Bulk Design Support
source SIGraDi 2006 - [Proceedings of the 10th Iberoamerican Congress of Digital Graphics] Santiago de Chile - Chile 21-23 November 2006, pp. 278-282
summary We introduce an architecture practice-oriented implementation strategy of constraint-based methods called BDS (Building Bulk Design Support) to supporting bulk analysis during the architectural programming phase. We examine the optmization problem of site coverage and building massing according to a set of standard planning and zoning regulations, and try a problem solving approach based on the paradigm of constraint satisfaction problems. The case study, which is focused on the paticipatory planning of very low-income dwellings within the Latin American context, serves as testbed for a prototypical application of the adopted methodology. The BDS constitutes a novel approach on computer-aided bulk analysis, regarding this particularly relevant context of application. In the case of participatively planned low-income housing projects, efficiency regarding time and cost of planning directly affects dwellers’ quality of life, whereas elementary programming tasks such as bulk analysis lack appropriate state-of-the-art technological support. Traditional architectural planning methods demand a large domain-specific knowledge base and skillful planners. A planning process, which is mainly driven by the formulation of planning-relevant constraints and sets of solution alternatives, suggests to avoid architects’ traditional procedure of: 1. Create an (yet not necessarily valid) instance of the eventual design solution by directly choosing specific values for its shape parameters. 2. Evaluate its validity by confronting the designed model to a set of applicable constraints, which have to be satisfied. Instead, the constraint-based design methodology poses a search procedure that operates in a space of pertinent constraint sets. A computer-aided interactive search procedure to find more valid design solution alternatives in less time and with less effort is particularly qualified to supply efficient support for participatory planning activities carried out between dwellers and planners. The set of solutions for a building-bulk design problem is constrained by both a large complex system of planning and zoning regulations and the geometry of the eventual design solution itself. Given a considerable amount of such regulations, a regular size geometric constraint satisfaction system proved to be capable of providing a highly efficient, interactive modeling and evaluation tool for the formulation in real time of valid solution alternatives for an ordinary building-bulk design problem. A BDS implementation will constitute one system module of a larger integrated system model called Esther. A BDS tool shall interact with other functional modules, like e.g. the FLS (Floor plan Layout Support), which also uses constraint-based design methods.

title Foundations for a Constraint-Based Floor Plan Layout Support in Participatory Planning of Low-Income Housing
source SIGraDi 2006 - [Proceedings of the 10th Iberoamerican Congress of Digital Graphics] Santiago de Chile - Chile 21-23 November 2006, pp. 283-287
summary We introduce the foundations of a novel approach that deals with constraint-based design methods to supporting participatory planning processes of low-income dwellings. We examine the space allocation problem inside the architectural domain on the basis of graph theory and combinatorics, providing a concise mathematical background for an implementation strategy called FLS (Floor plan Layout Support), which is analyzed here for the first time regarding this particular context of application. The philosophy underlying a design method that is mainly driven by the formulation of distinct constraints suggests to avoid the traditional procedure of first to create a yet not necessarily valid instance of the eventual design solution by directly choosing specific parameter values of its shape, and later on to evaluate its validity by confronting the designed model to a set of applicable constraints. Instead, constraint-based design poses a search procedure that operates in a space of planning-relevant constraint sets. The FLS methodology integrates some few principles of constraint-based automated reasoning with high user interactivity, into a design environment where as much dwellers as planners can collaboratively work in solving spatial organization problems of housing projects. The FLS model of application makes use of a combination of dweller-specified constraints, planning and zoning regulations, and a small library of modular space units. Constraint-based design ! methods are particularly capable of supplying efficient support for the collaborative involvement of dwellers into the architectural programming process of her/his own home. Mainly, because dwellers themselves tend to describe their space need and design intentions as a set of constraints on room quantity, space utilization, circulation system, allocation of available furniture, available budget, construction time, and so forth. The goal is to achieve an integrated tool for finding and modelling topologically valid solutions for floor plan layout alternatives, by combining user-driven interactive procedures with automatic search and generative processes. Thus, several design alternatives can be explored in less time and with less effort than using mainstream procedures of architectural practice. A FLS implementation will constitute one system module of a larger integrated system model called Esther. A FLS tool shall interact with other functional modules, like e.g. the BDS (Building Bulk Design Support), which also uses constraint-based design methods. A preliminary procedural model for the FLS was tested on Chile’s official social housing standards (Chilean Building Code – OGUC. Art. 6.4.1) which are very similar to most Latin American housing programs currently in operation.

title The Argument for the Argument Revisiting the Architecture Machine

summary The argument for the argument, that is, the defense of the computable quantity, has had a profound impact on the contemporary understanding of design practice. In this paper, I explore the history of the architectural-computational ‘argument’ to uncover a generally accepted yet poorly understood collusion between architectural and urban theory, structuralist semantics, and computation. From arguments about the machine to the mechanics of language, and from the language of architecture to the architecture machine, the argument for the argument has radically transformed contemporary design practices, but neither the history nor the theory behind these developments has been critically examined. My own argument seeks to build upon this nexus a hypothetical construct – a post-structuralist computer – as a provocation of sorts: a challenge to contemporary computational work in architecture to critically and philosophically address its current trajectories.

title Urban space and architectural scale - Two examples of empirical research in architectural aesthetics
source Motion, E-Motion and Urban Space [Proceedings of the 7th European Architectural Endoscopy Association Conference / ISBN-10: 3-00-019070-8 - ISBN-13: 978-3-00-019070-4], pp. 133-149
summary As one of the oldest schools of architecture in Germany, Dresden has a long and continuous tradition in the field of architectural aesthetics and building composition. Architects such as Fritz Schumacher initiated research and teaching in the field in the 1920s, and this was revitalised during the 1950s by Otto Schubert who laid the foundations for a scientific description of the correlation between optics and architectural design, and also worked towards a comprehensive theory of architectural composition. As a result of the architectural ideology of the East German regime, such studies were consigned to near oblivion and the main concern became interior decoration. With the appointment of Professor Ralf Weber, the institute was reestablished in 1994 under its original name, the Institute of Spatial Design (Raumgestaltung). Its new research agenda originated from Weber’s book “On the Aesthetics of Architectural Form - A Psychological Approach to the Structure and the Order of Perceived Architectural Space” (Ashgate 1994). In order to verify some of the hypotheses advanced in the book empirically, members of the institute have been carrying out a number of studies in the areas of oculomotor research and the perceptual foundations of design, and have been addressing issues that would help formulate principles of good architectural form and space applicable to the everyday practice of architectural design. Currently, the Institute of Spatial Design focuses on the further development of the psychological bases of experiencing architecture, as well as on theories of aesthetics and their application in practice. Specifically, attention is paid, on the one hand, to the perception and experience of architecture, i.e. aesthetics, and on the other, to the assemblage of various parts into an overall whole in a building, city or landscape – in other words, architectural composition. These two aspects are naturally inextricably intertwined: the one concerns the reception of architecture, the other, its production. Under these headings, various other areas of interest, such as architectural tectonics, systems of order and proportions, or the issue of scale in architecture, are tackled through dissertations, research projects and seminars. The institute has been cooperating on several studies with the Cognitive & Biological Psychology Unit at the University of Leipzig and the intention is eventually to establish an interdisciplinary research unit for architectural aesthetics.

title Adaptive Generative Patterns: design and construction of Prague Biennale pavilion
source Computing in Architecture / Re-Thinking the Discourse: The Second International Conference of the Arab Society for Computer Aided Architectural Design (ASCAAD 2006), 25-27 April 2006, Sharjah, United Arab Emirates
summary This paper describes an experimental practice-based research project that considered design process, implementation and construction of a pavilion built to be part of the Performative Space section of the International Biennale of Contemporary Art, Prague 2005. The project was conceptualized as a time-bound performative situation with a parasite-like relationship to its host environment. Its design has emerged through an innovative iterative process that utilized digital simulative and procedural techniques and was formed in response to place-specific behavioral challenges. This paper presents the project as an in-depth case-study of digital methods in design, mass customization and unified methods of production. In particular, it considers the use of Voronoi patterns for production of structural elements providing detail on programming and construction techniques in relationship to design aspirations and practical constraints.

title Parametricism for Urban Aesthetics - A flawless order behind chaos or an over-design of complexity
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. 105-112
summary Over the last decade, paradigm shifts in the philosophy of space-time relations, the change from space-time to spatio-temporality, caused significant changes in the design field, and introduced new variations and discourses for parametric approaches in architecture. Among all the discourses, parametricism is likely the most spectacular one. The founder of parametricism, Patrik Schumacher (2009) describes it as “a new style,” which has “the superior capacity to articulate programmatic complexity;” and “aesthetically, it is the elegance of ordered complexity in the sense of seamless fluidity.” In its theoretical background, Schumacher (2011) affiliates this style with the philosophy of autopoiesis, the philosophy that stands between making and becoming. Additionally, parametricism concerns not only the physical geometry in making of form; but also discusses the relational and causal aspects in becoming of form. In other words, it brings the aesthetic qualities in making through the topological intelligence behind becoming. Regarding that, parametricism seems an effective way of managing /creating complex topologies in form-related issues. However, when it comes to practice, there are some challenging points of parametricism in large-scale design studies. Thus, this work underlines that the dominance of elegance for urban planning has the potential of limiting the flexible and dynamic topology of the urban context, and objectifying the whole complex urban form as an over-designed product. For an aesthetic inquiry into urban parametricism, this paper highlights the challenging issues behind the aesthetic premises of parametricism at the urban design scale. For that, Kartal Master Plan Design Proposal by Zaha Hadid Architects (2006) will be discussed as an exemplary work.

title Space, Events and Urban Performance
source SIGraDi 2006 - [Proceedings of the 10th Iberoamerican Congress of Digital Graphics] Santiago de Chile - Chile 21-23 November 2006, pp. 333-336
summary This report investigates different kinds of Urban Performance in Thames Path, South Bank of Thames River. Urban Performance is defined here as the expression or manifestation of different social groups in the city space regarding the appropriation of a specific place for its spatial practices. The Urban Performances are intrinsic to the cultural expression of the city and revealed through the spatial experience of both performer and spectator. The aim of this paper is to shed light on different kind of urban performances and how are they linked to spatial and syntactic properties of space. This topic is intrinsic in the space syntax theory due its fundamental relation between spatiality and human activity. The research method used were, direct observations by static snapshots and traces (related with human movement) and a survey of potential attractors, active facades and path widths. The results were overlaid with spatial analysis in terms of performers isovists and syntactic analysis through visibility graph. The findings show a strong relation between performers’ use of space and visibility in the urban area, and a high influence of the cultural attractions and public services that works as movement attractors. The discussion is developed through the research findings and theories of spatial experience putting forward varied interpretations related with the research topic and the selected site. The report concludes that the urban performances in Thames path is determined by the human co presence in the space, due to this strategic points chosen along the path by the performers are strongly related with the visual connections in the system. Furthermore, the attractors play an important role shaping the spatial experience and urban character of the studied area.

summary Urban pedestrian studies on navigation have been conducted for developing applications to ease the task of exploring in a virtual environment. As navigation in virtual environments is evidently difficult and as many virtual worlds have been designed to be used by untrained visitors that explore the environment, navigational supports are critically needed. This study is aimed to collect information about the user needs in order to build a model of user preference and produce simulative scenarios that can reveal the navigational patterns related to street design. The study is based on the attention theory for studying people who are socially interacting with street activities and furniture within designated areas. Furthermore, the study attempts to apply agent interface develop a prototype system with space tags. Finally, the system and its applications, and major findings of these applications are reported

source SIGraDi 2006 - [Proceedings of the 10th Iberoamerican Congress of Digital Graphics] Santiago de Chile - Chile 21-23 November 2006, pp. 56-60
summary The study describes some of the aspects tackled within a current Ph.D. research where architectural applications of constructive, structural and organization processes existing in biological systems are considered. The present information processing capacity of computers and the specific software development have allowed creating a bridge between two holistic nature disciplines: architecture and biology. The crossover between those disciplines entails a methodological paradigm change towards a new one based on the dynamical aspects of forms and compositions. Recent studies about artificial-natural intelligence (Hawkins, 2004) and developmental-evolutionary biology (Maturana, 2004) have added fundamental knowledge about the role of the analogy in the creative process and the relationship between forms and functions. The dimensions and restrictions of the Evo-Devo concepts are analyzed, developed and tested by software that combines parametric geometries, L-systems (Lindenmayer, 1990), shape-grammars (Stiny and Gips, 1971) and evolutionary algorithms (Holland, 1975) as a way of testing new architectural solutions within computable environments. It is pondered Lamarck´s (1744-1829) and Weismann (1834-1914) theoretical approaches to evolution where can be found significant opposing views. Lamarck´s theory assumes that an individual effort towards a specific evolutionary goal can cause change to descendents. On the other hand, Weismann defended that the germ cells are not affected by anything the body learns or any ability it acquires during its life, and cannot pass this information on to the next generation; this is called the Weismann barrier. Lamarck’s widely rejected theory has recently found a new place in artificial and natural intelligence researches as a valid explanation to some aspects of the human knowledge evolution phenomena, that is, the deliberate change of paradigms in the intentional research of solutions. As well as the analogy between genetics and architecture (Estévez and Shu, 2000) is useful in order to understand and program emergent complexity phenomena (Hopfield, 1982) for architectural solutions, also the consideration of architecture as a product of a human extended phenotype can help us to understand better its cultural dimension.

summary The choice of a chord and its execution should be regarded as a must and not left to arbitrary wish or superficial speculation. (Johannes Itten, 1961) The paper describes a modular concept for the IT-support of planning practice using BIM (Building Information Modelling) and a parameterized building model. The platform used is the modularized software concept for architectural planning in existing built contexts (prototype software FREAK). The current progress in the development of a reasoned support of planning tasks is described in this paper in more detail. The system consists of a series of software prototypes which are linked to the BIM, utilize the specific data within and demonstrate the value of a consistent and extendable CAD-model. The “Colored Architecture” software prototype is one such design-support module of the software platform and enables the designer to experiment with the parameters colour, light and materials in architectural space. This module supports experimentation, assessment and realization of colours and materials in the architectural design process on a new quality. For instance, the integration of “live radiosity” light simulation allows a qualified and interactive assessment and evaluation of colours and materials in near-real lighting conditions. The paper also details further software prototypes, modules and concepts including building surveying and the design of self-supporting domed structures.

summary This paper investigates new design methods, showing the experimental use of new digital tools, CNC-techniques and technologies so as to expand the definition of contemporary architecture. This investigation of new technologies extends the traditional practice of architectural design to include issues of design, multimedia, programming, control systems and fabrication by using computer controlled machines. The main teaching and research focus of the Master of Advanced Studies in Architecture (MAS), Specialization in Computer Aided Architectural Design (CAAD), Prof. Dr. Ludger Hovestadt, is the computer based architectural design and its automated production. The aim of our research and teaching project is to achieve a close connection between design and production by embedding the “digital chain” in the whole process. The digital chain is a design and production sequence with no analogue steps; the process offers high flexibility in terms of design and production. The use of new digital tools in architecture extends the profession beyond traditional design.

title Road hierarchy and speed limits in Brasília/Brazil
source H.J.P. Timmermans, B. de Vries (eds.) 2008, Design & Decision Support Systems in Architecture and Urban Planning, ISBN 978-90-6814-173-3, University of Technology Eindhoven, published on CD
summary This paper aims at exploring the theory of the Social Logic of Space or Space Syntax as a strategy to define parameters of road hierarchy and, if this use is found possible, to establish maximum speeds allowed in the transportation system of Brasília, the capital city of Brazil. Space Syntax – a theory developed by Hillier and Hanson (1984) – incorporates the space topological relationships, considering the city shape and its influence in the distribution of movements within the space. The theory’s axiality method – used in this study – analyses the accessibility to the street network relationships, by means of the system’s integration, one of its explicative variables in terms of copresence, or potential co-existence between the through-passing movements of people and vehicles (Hillier, 1996). One of the most used concepts of Space Syntax in the integration, which represents the potential flow generation in the road axes and is the focus of this paper. It is believed there is a strong correlation between urban space-form configuration and the way flows and movements are distributed in the city, considering nodes articulations and the topological location of segments and streets in the grid (Holanda, 2002; Medeiros, 2006). For urban transportation studies, traffic-related problems are often investigated and simulated by assignment models – well-established in traffic studies. Space Syntax, on the other hand, is a tool with few applications in transport (Barros, 2006; Barros et al, 2007), an area where configurational models are considered to present inconsistencies when used in transportation (cf. Cybis et al, 1996). Although this is true in some cases, it should not be generalized. Therefore, in order to simulate and evaluate Space Syntax for the traffic approach, the city of Brasília was used as a case study. The reason for the choice was the fact the capital of Brazil is a masterpiece of modern urban design and presents a unique urban layout based on an axial grid system considering several express and arterial long roads, each one with 3 to 6 lanes,

summary Expanding bodies of knowledge imply expanding teams to manage this knowledge. Paradoxically, it can be shown that in situations of complexity—which increasingly characterise the production of architecture generally—the small practice or small team could be at an advantage. This is due to the increasingly digital nature of the work undertaken and artefacts produced by practices, enabling production processes to be augmented with digital toolsets and for tight project delivery networks to be forged with other collaborators and consultants (Frazer 2006). Furthermore, as Christensen argues, being small may also be desirable, as innovations are less likely to be developed by large, established companies (Christensen 1997). By working smarter, and managing the complexity of design and construction, not only can the small practice “punch above its weight” and compete with larger practices, this research suggests it is a more appropriate model for practice in the digital age. This paper demonstrates this through the implementation of emerging technologies and strategies including generative and parametric design, digital fabrication, and digital construction. These strategies have been employed on a number of built and un-built case-study projects in a unique collaboration between RMIT University’s SIAL lab and the award-winning design practice BKK Architects.

summary Our research work concerns the development of a multimodal urban traffic simulator designed to be a tool of decision-making aid similar to a game wherein the user-player can test different scenarios by immersion in a 3D virtual city. Our approach is based on the activity-based model and the multi-agent technology. The implemented result is a hybrid simulator connecting numerical simulation and behavioural aspects coming from real data. This paper is focused on two points: firstly, we introduce how a final user (the traffic regulator) instantiates and assembles components so as to model a city and its urban traffic network; secondly, we present the use of Dempster-Shafer theory in the context of discrete choice modelling. Our approach manipulates input variables in order to test realistic representations of behaviours of agent categories in a decision-making process. The traffic modelling is based on a questionnaire elaborated from standard arrays of Taguchi. The significant variables and interactions are determined with the analysis of variance which suggests a reduced model describing the behaviour of a particular social category. The belief theory is used to take into account the doubt of some respondents as well as for the preferences redistribution if the number of alternatives changes. The effects of external traffic conditions are also quantified to choose a 'robust' alternative and to use the agents' memory.

source Computing in Architecture / Re-Thinking the Discourse: The Second International Conference of the Arab Society for Computer Aided Architectural Design (ASCAAD 2006), 25-27 April 2006, Sharjah, United Arab Emirates
summary This research investigates architectural conceptual design and discusses its recent historical, philosophical and theoretical development within the overall architectural design process and attempts to establish an objective definition more tuned to current thinking and advancement in technology. It also evaluates the various traditional and information technology (IT) tools available to the designer and establishes their relationship to the conceptual design process in order to identify if any of these tools, in particular the IT tools, have a role to play in the practice and the enhancement of the conceptual design process. A survey of Scottish practicing architects (small to medium size practices) was undertaken to validate the results of the investigation. The results seem to suggest that IT tools are not essential to the conceptual design process but that they are very well capable of enhancing the creativity and speed of some aspects of it. They also suggest the existence of an inherent resistance amongst Architects / designers to utilising these tools in conceptual design. It is, furthermore, identified that if practitioners were to encompass new working practices and acquire new skills, IT tools could also provide powerful new modes of communication with the client. A correlation between the size of the practice and the degree of exposure and experience of IT tools was also established. To test some of the above findings, a design studio experiment was undertaken where half of the students adopted digital tools, utilising SketchUp software and digital sketchpads, whilst the others adopted traditional tools for the conceptual design part of their projects. No attempt was made to gauge the quality of the actual designs produced. The results indicate that the SketchUp group rated their conceptual design experience higher in terms of efficiency, flexibility and communication. The control group, who had dominantly adopted traditional freehand sketching, were impressed by the outcome from the SketchUp group. All student who answered the questionnaire, both SketchUp and control groups, said they would consider adopting some form of 3D sketching in the future.

title Gentrification Waves in the Inner-City of Milan - A multi agent / cellular automata model based on Smith's Rent Gap theory
source Van Leeuwen, J.P. and H.J.P. Timmermans (eds.) 2006, Innovations in Design & Decision Support Systems in Architecture and Urban Planning, Dordrecht: Springer, ISBN-10: 1-4020-5059-3, ISBN-13: 978-1-4020-5059-6, p. 187-201
summary The aim of this paper is to investigate the gentrification process by applying an urban spatial model of gentrification, based on Smith's (1979; 1987; 1996) Rent Gap theory. The rich sociological literature on the topic mainly assumes gentrification to be a cultural phenomenon, namely the result of a demand pressure of the suburban middle and upper class, willing to return to the city (Ley, 1980; Lipton, 1977, May, 1996). Little attempt has been made to investigate and build a sound economic explanation on the causes of the process. The Rent Gap theory (RGT) of Neil Smith still represents an important contribution in this direction. At the heart of Smith's argument there is the assumption that gentrification takes place because capitals return to the inner city, creating opportunities for residential relocation and profit. This paper illustrates a dynamic model of Smith's theory through a multi-agent/ cellular automata system approach (Batty, 2005) developed on a Netlogo platform. A set of behavioural rules for each agent involved (homeowner, landlord, tenant and developer, and the passive 'dwelling' agent with their rent and level of decay) are formalised. The simulations show the surge of neighbouring degradation or renovation and population turn over, starting with different initial states of decay and estate rent values. Consistent with a Self Organized Criticality approach, the model shows that non linear interactions at local level may produce different configurations of the system at macro level. This paper represents a further development of a previous version of the model (Diappi, Bolchi, 2005). The model proposed here includes some more realistic factors inspired by the features of housing market dynamics in the city of Milan. It includes the shape of the potential rent according to city form and functions, the subdivision in areal submarkets according to the current rents, and their maintenance levels. The model has a more realistic visualisation of the city and its form, and is able to show the different dynamics of the emergent neighbourhoods in the last ten years in Milan.

title Digital Tools for Sustainable Revitalization of Buildings - Finding new Utilizations through Destructive and Non-Destructive Floor Space Relocation
source Proceedings of the International Conference on Urban, Architectural and Technical Aspects of the Renewal of the Countryside IV., Bratislava, May 2006
summary In 1845 Edgar Allan Poe wrote the poem “The Raven”, an act full of poetry, love, passion, mourning, melancholia and death. In his essay “The Theory of Composition” which was published in 1846 Poe proved that the poem is based on an accurate mathematical description. Not only in literature are structures present that are based on mathematics. In the work of famous musicians, artists or architects like Bach, Escher or Palladio it is evident that the beauty and clarity of their work as well as its traceability has often been reached through the use of intrinsic mathematic coherences. If suchlike structures could be described within architecture, their mathematical abstraction could supplement “The Theory of Composition” of a building. This research focuses on an approach to describe layout principles of existing buildings in the form of mathematical rules. Provided that “design” is in principle a combinatorial problem, i.e. a constraint-based search for an overall optimal solution of a design problem, two exemplary methods will be described to apply new utilizations to existing buildings through the use of these rules.

title Structural Performance Modelling in Architectural Design Education
source Computing in Architecture / Re-Thinking the Discourse: The Second International Conference of the Arab Society for Computer Aided Architectural Design (ASCAAD 2006), 25-27 April 2006, Sharjah, United Arab Emirates
summary In architectural education the process of design has evolved with the development of CAD technology. In many design schools throughout the world, the computer has extended its role beyond that of a drafting machine to become a tool for performance modeling. Applications currently used by students test lighting, thermal conditions, and structural validity, to name a few. However the goals in education are not identical to those in practice, and digital modeling can support learning in many ways that are not particularly useful or appropriate in professional practice. In the design of structures there are three fundamental levels of understanding: behavior, form, and performance. Each has its place in design education and uses digital modeling in different forms. This paper describes various pedagogical models that incorporate computer aided drawing and performance modeling in the teaching of structures. Examples of student exercises and projects are discussed.

title Designing with Machines: solving architectural layout planning problems by the use of a constraint programming language and scheduling algorithms
source Computing in Architecture / Re-Thinking the Discourse: The Second International Conference of the Arab Society for Computer Aided Architectural Design (ASCAAD 2006), 25-27 April 2006, Sharjah, United Arab Emirates
summary In 1845 Edgar Allan Poe wrote the poem “The Raven”, an act full of poetry, love, passion, mourning, melancholia and death. In his essay “The Theory of Composition” which was published in 1846 Poe proved that the poem is based on an accurate mathematical description. Not only in literature are structures present that are based on mathematics. In the work of famous musicians, artists or architects like Bach, Escher or Palladio it is evident that the beauty and clarity of their work as well as its traceability has often been reached through the use of intrinsic mathematic coherences. If suchlike structures could be described within architecture, their mathematical abstraction could supplement “The Theory of Composition” of a building. This research focuses on an approach to describe principles in architectural layout planning in the form of mathematical rules that will be executed by the use of a computer. Provided that “design” is in principle a combinatorial problem, i.e. a constraint-based search for an overall optimal solution of a design problem, an exemplary method will be described to solve problems in architectural layout planning. Two problem domains will be examined: the design of new buildings, as well as the revitalization of existing buildings. Mathematical and syntactical difficulties that arise from the attempt to extract rules that relate to the process of building design will be pointed out. To avoid conflicts relating to theoretical subtleness a customary approach has been chosen in this work which is adopted from Operations Research. In this approach design is a synonym for planning, which could be described as a systematic and methodical course of action for the analysis and solution of current or future problems. The planning task is defined as an analysis of a problem with the aim to prepare optimal decisions by the use of mathematical methods. The decision problem of a planning task is represented by an optimization model and the application of an efficient algorithm to aid finding one or more solutions to the problem. The basic principle underlying the approach presented herein is the understanding of design in terms of searching for solutions that fulfill specific criteria. This search will be executed by the use of a constraint programming language, which refers to mathematical as well as to integer and mixed integer programming. Examples of architectural layout problems will be presented that can be solved by the use of this programming paradigm. In addition to this, a second programming approach resulting from the domain of resource-allocation has been followed in this research. It will be demonstrated that it is as well possible, to aid architectural layout planning by the use of scheduling algorithms.
