title	Crowd Modeling and Simulation
source	Van Leeuwen, J.P. and H.J.P. Timmermans (eds.) Recent Advances in Design & Decision Support Systems in Architecture and Urban Planning, Dordrecht: Kluwer Academic Publishers, ISBN: 1-4020-2408-8, p. 161-175
summary	The paper introduces a Multi Agent Systems (MAS) approach to crowd modelling and simulation, based on the Situated Cellular Agents (SCA) model. This is a special class of Multilayered Multi Agent Situated System (MMASS), exploiting basic elements of Cellular Automata. In particular SCA model provides an explicit spatial representation and the definition of adjacency geometries, but also a concept of autonomous agent, provided with an internal architecture, an individual state and behaviour. The latter provides different means of space-mediated interaction among agents: synchronous, between adjacent agents, and asynchronous among at-a-distance entities. Heterogeneous entities may be modelled through the specification of different agent types, defining different behaviours and perceptive capabilities. After a brief description of the model, its application to simple crowd behaviours will be given, and an application providing the integration of a bidimensional simulator based on this model and a 3D modelling application (3D Studio) will also be described. The adoption of this kind of system allows the specification and simulation of an architectural design with reference to the behaviour of entities that will act in it. The system is also able to easily produce a realistic visualization of the simulation, in order to facilitate the evaluation of the design and the communication with involved decision-makers. In fact, while experts often require only abstract and analytical results deriving from a quantitative analysis of simulation results, other people involved in the decision-making process related to the design may be helped by qualitative aspects better represented by other forms of graphical visualization.

title	A Review of Object Oriented CAD Potential for Building Information Modeling and Life Cycle Management
source	eDesign in Architecture: ASCAAD's First International Conference on Computer Aided Architectural Design, 7-9 December 2004, KFUPM, Saudi Arabia
summary	In many countries, the Architecture/Engineering/Consulting (AEC) industry is characterised by poor performance reflected in project delays and cost overruns. A contributor to the problem is the traditional approach to handling building information and its communication in life cycle management (LCM). Recent developments in Object Oriented Computer Aided Architectural Design (OO CAD) have provided the opportunity for improving building information modelling and its communication for more effective LCM. The aim of the paper is to review the potentials of OO CAD for building information modelling (BIM) and LCM. The paper reviews building information in the life cycle process, identifying the various actors and activities and the need for communication and information flow to support life cycle management. The paper also reviews the concept of OO CAD, highlighting its potential to improve building information and its flow and communication in life cycle management. The paper then goes on to review the potentials and limitations of OO CAD implementation in the AEC industry. The paper concludes by pointing out that the widespread adoption of OO CAD and the anticipated associated improvement in life cycle management will only be encouraged when the building industry is able to agree on a widely acceptable, interoperable standard for encoding building objects.

title	Irradiated Shade
doi	https://doi.org/10.52842/conf.acadia.2020.1.038
source	ACADIA 2020: Distributed Proximities / Volume I: Technical Papers [Proceedings of the 40th Annual Conference of the Association of Computer Aided Design in Architecture (ACADIA) ISBN 978-0-578-95213-0]. Online and Global. 24-30 October 2020. edited by B. Slocum, V. Ago, S. Doyle, A. Marcus, M. Yablonina, and M. del Campo. 38-46.
summary	The paper details computational mapping and modeling techniques from an ongoing design research project titled Irradiated Shade, which endeavors to develop and calibrate a computational toolset to uncover, represent, and design for the unseen dangers of ultraviolet radiation, a growing yet underexplored threat to cities, buildings, and the bodies that inhabit them. While increased shade in public spaces has been advocated as a strategy for “mitigation [of] climate change” (Kapelos and Patterson 2014), it is not a panacea to the threat. Even in apparent shade, the body is still exposed to harmful, ambient, or “scattered” UVB radiation. The study region is a binational metroplex, a territory in which significant atmospheric pollution and the effects of climate change (reduced cloud cover and more “still days” of stagnant air) amplify the “scatter” of ultraviolet wavelengths and UV exposure within shade, which exacerbates urban conditions of shade as an “index of inequality” (Bloch 2019) and threatens public health. Exposure to indirect radiation correlates to the amount of sky visible from the position of an observer (Gies and Mackay 2004). The overall size of a shade structure, as well as the design of openings along its sides, can greatly impact the UV protection factor (UPF) (Turnbull and Parisi 2005). Shade, therefore, is more complex than ubiquitous urban and architectural “sun” and “shadow studies” are capable of representing, as such analyses flatten the three-dimensional nature of radiation exposure and are “blind” to the ultraviolet spectrum. “Safe shade” is contingent on the nuances of the surrounding built environment, and designers must be empowered to observe and respond to a wider context than current representational tools allow.

title	The New Combination of Digital Sketching and Modeling Process in Idea-Developing Stage
doi	https://doi.org/10.52842/conf.caadria.2004.545
source	CAADRIA 2004 [Proceedings of the 9th International Conference on Computer Aided Architectural Design Research in Asia / ISBN 89-7141-648-3] Seoul Korea 28-30 April 2004, pp. 545-556
summary	With the introduction of the computer into different forms of digital applications in the design process, Mitchell strongly recommended a wider application of the new technology in the design process -- implying the mutual influence between physical architecture and the sketches, and between physical and digital models. Most important is the possibility of using computer aided design (CAD) to develop ideas in early design stage. During the developing idea stage, the traditional design process from sketching drawings to forming ideas has been transformed to a process where the idea directly proceeds to computer modeling. The aim of this approach is to tackle the above issues created by the introduction of computer technology, trying to produce the same possibilities during the computer modeling process as that in the cognitive behavior of sketching. Also, the designer usually realizes the abstract concepts with the aid of the 2D sketches and the 3D physical models; but between the traditional sketches and the models, a large degree of disagreement always exists. Therefore, this work aims to develop a new formula for employing digital media, which will enable the designer to envisage 2D sketches and computer models simultaneously. In this scenario, the designer can remain aware of cognitive behavior in sketching while constructing computer models.

title	Location Modeling for Ubiquitous Computing Based on a Spatial Information Management Technology
doi	https://doi.org/10.52842/conf.caadria.2004.787
source	CAADRIA 2004 [Proceedings of the 9th International Conference on Computer Aided Architectural Design Research in Asia / ISBN 89-7141-648-3] Seoul Korea 28-30 April 2004, pp. 787-802
summary	Location modeling, which generally has influence on location-aware applications, is a critical and interesting aspect. In the ubiquitous computing, location modeling has been discussed as one of fundamental research subject, because a location is a very essential element of contexts and useful information for other applications related with ubiquitous computing. Especially, location modeling in architectural space should be defined through the comprehension of the physical environment, because the users' (or objects) location does not only mean numerical coordinates, but also refers to the situation related to users' (or objects) physical contexts. In other hands, location model for architectural space should be based on the simplification of complicated physical environment, the consideration of corresponding various changes, and also the definition for the relationship of spatial information. Traditionally, those issues have been actively studied in the fields of CAAD (Computer Aided Architectural Design) research and could used effectively for ubiquitous computing system. This paper proposes the location model and its utilization method which can be applied on making the ubiquitous computing system in the architectural space based on CAAD theories. At the end of the paper, we present a CAAD system, called “Vitruius”, in order to define architectural spaces appropriately and manage them easily for the ubiquitous computing environment.

title	GEOMETRY AND ARCHITECTURE: NURBS, DESIGN AND CONSTRUCTION
source	Proceedings of the Fourth International Conference of Mathematics & Design, Special Edition of the Journal of Mathematics & Design, Volume 4, No.1, pp. 135-139.
summary	Geometry regarded as a tool for understanding is perhaps the part of Mathematics which is the most intuitive, concrete and linked to reality. From its roots as a tool to describe and measure shapes, geometry as ‘the space science’ , has grown towards a theory of ideas and methods by means of which it is possible to build and study idealised models, not only from the physical world but also from the real world. In graphic architecture thought, geometry usually appears as an instrumental support for project speculation. Geometric procedures are presented as representational resources for the graphic testing of reflection and for the exposition of ideas in order to build a logical order as regards representation and formal prefiguration. The fast rise of computing in the last decades has made it possible for architects to work massively and in a graphic and intuitive way with mathematical representations of tridimensional geometry, such as the NURBS . These organic surfaces of free shapes defined by vectorial curves have allowed access to a rapid generation of complex shapes with a minumum amount of data and of specific knowledge. The great development of modelling achieved by the digital media and the limitations in the technical and building areas and in the existence of materials which are coherent with the resultant shapes reveal a considerable distance between the systems of ideation and simulation characteristic of the computing era and the analogous systems of production inherited from the slow industrial development. This distance has been shortened by CAD/CAM systems, which are, however, not very accessible to the architectural field. If we incorporate to the development of these divergent media the limitations which are distinctive of the material resources and procedures of the existent local technology, the aforementioned distance seems even greater. Assuming the metaphor of living at the threshold of two ages (industrial-computing, analogical-digital, material-virtual) and the challenge of the new conceptual and operational tools in our field, we work in the mixture, with no exclusions or substitutions, proposing (by means of the development of informational complements) some alternatives of work to approach the issue under discussion from the Architecture Workshop.

title	Improved Understanding of Urban Sprawl Using Neural Networks
source	Van Leeuwen, J.P. and H.J.P. Timmermans (eds.) Recent Advances in Design & Decision Support Systems in Architecture and Urban Planning, Dordrecht: Kluwer Academic Publishers, ISBN: 14020-2408-8, p. 33-49
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	Developing Architectonic Language Through Digital Observation
doi	https://doi.org/10.52842/conf.ecaade.2004.269
source	Architecture in the Network Society [22nd eCAADe Conference Proceedings / ISBN 0-9541183-2-4] Copenhagen (Denmark) 15-18 September 2004, pp. 269-277
summary	The question for architects is always how to begin. This proposal attempts to illustrate a design methodology that is characterised by its attention to non-traditional generators. The focus of the paper is the definition of an innovative design process characterised by the production of an architectonic language through the observation of the ephemeral and the transitory (the quanta of place), and which pays cognisance to the realization of a three-dimensional narrative, placing value upon the products of investigation as well as the resultant design. As the title suggests the process outlined concerns itself with the examination of the ephemeral, the transitory and the unobserved. The overriding concern is with the recording of fragments of a chosen environment (site) and, the collation and depiction of these findings in an alternative three-dimensional environment (virtual space). This process is only made possible by the advent of computer applications capable of generating the complexity of three-dimensional environments needed to explore the plethora of forms generated by the initial recordings. This process is concerned with the nascence of architectural expression and the formalising of architectural propositions composed from an individual’s interpretation of the ‘space between’, the obvious and the immaterial, and the phenomena that exist there. The generators are the things beyond immediate perception. They are the quanta of place. It is this process of capturing fixed moments in time and space and, translating imperceptible nanomoments and nanoevents, that allows for the development of exploratory diagrams constructed over a backdrop of credible analysis. These make apparent the infinite possibilities for further transition whilst illustrating the conceptual lineage that links each instance to its antecedents. The resultant physical forms embody the essence of something transformed. They possess cultural and emotional syntax. They become mementos in the landscape.

title	Between Mediation and Making CIMSp: A Technoètic Modus Operandi
doi	https://doi.org/10.52842/conf.ecaade.2004.435
source	Architecture in the Network Society [22nd eCAADe Conference Proceedings / ISBN 0-9541183-2-4] Copenhagen (Denmark) 15-18 September 2004, pp. 435-442
summary	The following paper describes an ongoing research project whose goal is to define a scalable, hybrid production and deployment protocol (CIMSp) for the creation of virtual environments (VE). Ultimately, the aim is to establish a creative workflow and infrastructure that embodies architectural and urban design activity as practiced by the research unit. The objective of the present paper is to schematically outline the current state of the research and its practical and theoretical context for further development. A theoretical position will be stated which assumes that the content, tool, epistemological, and speculative realms are consubstantial (technoèsis). The practical endeavour is to create the informational and embodied temporal--spatial condition of possibility for the imaginative production of cultural artifacts. It must accommodate varying individual and collaborative forms and styles of making and no presumption of a self-enclosed and referential system is made. A critical position is particularly compelling when this production is immersed in technological modalities of making where information and embodiment are inextricably intertwined. CIMSp is based on the workflow from acquisition and creation to output and storage. The work environment is comprised of a select set of software applications and visualization technologies. Secondly, an XML-based content and information management system is under construction to ensure project quality control, rigorous documentation practices, and bi-directional knowledge feedback procedures to enable an effective and resource-full workflow. Lastly, scalability of output modalities for use in the design process and for final presentation from WWW deployment to a high-resolution collaborative work environment (CWE) is being developed. The protocol is a multiuser mode of creation and production that aims to transform the technologies and their interrelation, thus dramatically impacting the creative process and intended content. It is a digital production workflow that embodies intensive visualization criteria demanded by the end users. The theoretical and practical intention of CIMSp is to provisionally structure the collaborative creative process and enable a choreographed movement between the realms of the technologically mediated and made in the pursuit of significant digital content creation.

title	HCIS: the Housing Context Inference System Model for Smart Space

summary	This research is about the basic methods in making computers understand human behavior in an architectural space in regards to reaction to interaction between the machine and human. Its ultimate objective is to analyze the related technology making this series of works possible synthetically on the basis of information system within architectural territoriality. In the end it is expected to offer a theoretical basis to embody smart space, up-to-date and intelligent architectural space. There are two issues that motivate this research: what are the Housing Context and its Inference System, and how smart space can infer the Housing Context and react with proper response. The Husing Context consists of 1) state of user, 2) state of physical environment, 3) state of computational environment, 4) history of user-environment interaction and 5) architectural territoriality. Especially, spatial information of architectural territoriality is a significant key of HCIS. Spatial divisions and boundaries made of architectural elements or facilities determinate their own micro-territorialities. Ontologies are used to describe the Housing Context predicate. In this paper, we can say that the Housing Context and the Housing Log(history of user-environment interaction, a set of the Housing Context) written by ontologies can be a beneficial model of HCIS. Furthermore, we can develop the Housing Log Databases and its variable applications that have enabled to make simulating and analyzing tool of design, the Augmented Web Presence and the other helpful applications.

title	MATHEMATICS AND DESIGN EDUCATION
source	Proceedings of the Fourth International Conference of Mathematics & Design, Special Edition of the Journal of Mathematics & Design, Volume 4, No.1, pp. 199-203.
summary	Many people believe that mathematical thought is an essential element of creativity. The origin of this idea in art dates back to Plato. Asserting that aesthetics is based on logical and mathematical rules, Plato had noticed that geometrical forms were “forms of beauty” in his late years. Unlike his contemporaries, he had stressed that the use of geometrical forms such as lines, circles, planes, cubes in a composition would aid to form an aesthetics. The rational forms of Plato and the rules of geometry have formed the basis of antique Greek art, sculpture and architecture and have influenced art and design throughout history in varying degrees. This emphasis on geometry has continued in modern design, reflected prominently by Kandinsky’s geometric classifications . Mathematics and especially geometry have found increasing application in the computer-based design environment of our day. The computer has become the central tool in the modern design environment, replacing the brush, the paints, the pens and pencils of the artist. However, if the artist does not master the internal working of this new tool thoroughly, he can neither develop nor express his creativity. If the designer merely learns how to use a computer-based tool, he risks producing designs that appear to be created by a computer. From this perspective, many design schools have included computer courses, which teach not only the use of application programs but also programming to modify and create computer-based tools. In the current academic educational structure, different techniques are used to show the interrelationship of design and programming to students. One of the best examples in this area is an application program that attempts to teach the programming logic to design students in a simple way. One of the earliest examples of such programs is the Topdown Programming Shell developed by Mitchell, Liggett and Tan in 1988 . The Topdown system is an educational CAD tool for architectural applications, where students program in Pascal to create architectural objects. Different examples of such educational programs have appeared since then. A recent fine example of these is the book and program called “Design by Number” by John Maeda . In that book, students are led to learn programming by coding in a simple programming language to create various graphical primitives. However, visual programming is based largely on geometry and one cannot master the use of computer-based tools without a through understanding of the mathematical principles involved. Therefore, in a model for design education, computer-based application and creativity classes should be supported by "mathematics for design" courses. The definition of such a course and its application in the multimedia design program is the subject of this article.

summary	Urban design is concerned with the shape, the surface and the physical arrangement of all kinds of urban elements, the basic components that make up the built environment, at the level of buildings, spaces and human activities. It is also concerned with the non-visual aspects of the environment, such as noise, wind and temperature and humidity. The city square is a particular urban element which can take many forms and its geometrical relationships such as maximum dimensions, ratio of width to length and building height to length have been analysed for centuries (Alberti 1475), (Vitruvius 1550), (Sitte 1889), (Corbett 2004). Within the current urban design process there are increasing examples of three dimensional computer representations which allow the user to experience a visual sense of the geometry of city squares in an urban landscape. Computer-aided design and Virtual Reality technologies have recently contributed to this visual assessment, but there have been limited attempts at 3D computer representations which allow the user to experience a greater sense of the urban space. This paper will describe a survey of computer tools which could support a more holistic approach to urban design and which could be used to simulate a number of urban texture and urban quality aspects. It will provide a systematic overview of currently available software that could support the simulation of building density, height, colour and style as well as conditions relating to noise, shading, heat, natural and artificial light. It will describe a methodology for the selection and filtering of appropriate computer applications and offer an initial evaluation of these tools for the analysis and representation of the three-dimensional geometry, urban texture and urban quality of city centre spaces. The paper is structured to include an introduction to the design criteria relating to city centre spaces which underpins this research. Next the systematic review of computer software will be described, and selected tools will undergo initial evaluation. Finally conclusions will be drawn and areas for future research identified.

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.

title	A Multi-dimensional Exploration of Urban Attributes by Data Mining

summary	The paper which is proposed here will introduce an ongoing research project aiming to research data mining as a methodology of knowledge discovery in urban feature analysis. To address the increasing multi-dimensional and relational complexity of urban environments requires a multidisciplinary approach to urban analysis. This research is an attempt to establish a link between knowledge discovery methodologies and automated urban feature analysis. Therefore, in the scope of this research we apply data mining methodologies for urban analysis. Data mining is defined as to extract important patterns and trends from raw data (Witten and Frank, 2005). When applied to discover relationships between urban attributes, data mining can constitute a methodology for the analysis of multi-dimensional relational complexity of urban environments (Gil, Montenegro, Beirao and Duarte, 2009) The theoretical motivation of the research is derived by the lack of explanatory urban knowledge which is an issue since 1970‚Äôs in the area of urban research. This situation is mostly associated with deductive methods of analysis. The analysis of urban system from the perspective of few interrelated factors, without considering the multi-dimensionality of the system in a deductive fashion was not been explanatory enough. (Jacobs, 1961, Lefebvre, 1970 Harvey, 1973) To address the multi-dimensional and relational complexity of urban environments requires the consideration of diverse spatial, social, economic, cultural, morphological, environmental, political etc. features of urban entities. The main claim is that, in urban analysis, there is a need to advance from traditional one dimensional (Marshall, 2004) description and classification of urban forms (e.g. Land-use maps, Density maps) to the consideration of the simultaneous multi-dimensionality of urban systems. For this purpose, this research proposes a methodology consisting of the application of data mining as a knowledge discovery method into a GIS based conceptual urban database built out of official real data of Beyoglu. Generally, the proposed methodology is a framework for representing and analyzing urban entities represented as objects with properties (attributes). It concerns the formulation of an urban entity‚Äôs database based on both available and non-available (constructed from available data) data, and then data mining of spatial and non-spatial attributes of the urban entities. Location or position is the primary reference basis for the data that is describing urban entities. Urban entities are; building floors, buildings, building blocks, streets, geographically defined districts and neighborhoods etc. Urban attributes are district properties of locations (such as land-use, land value, slope, view and so forth) that change from one location to another. Every basic urban entity is unique in terms of its attributes. All the available qualitative and quantitative attributes that is relavant (in the mind of the analyst) and appropriate for encoding, can be coded inside the computer representation of the basic urban entity. Our methodology is applied by using the real and official, the most complex, complete and up-to-dataset of Beyoglu (a historical neighborhood of Istanbul) that is provided by the Istanbul Metropolitan Municipality (IBB). Basically, in our research, data mining in the context of urban data is introduced as a computer based, data-driven, context-specific approach for supporting analysis of urban systems without relying on any existing theories. Data mining in the context of urban data; ‚Ä¢ Can help in the design process by providing site-specific insight through deeper understanding of urban data. ‚Ä¢ Can produce results that can assist architects and urban planners at design, policy and strategy levels. ‚Ä¢ Can constitute a robust scientific base for rule definition in urban simulation applications such as urban growth prediction systems, land-use simulation models etc. In the paper, firstly we will present the framework of our research with an emphasis on its theoretical background. Afterwards we will introduce our methodology in detail and finally we will present some of important results of data mining analysis processed in Rapid Miner open-source software. Specifically, our research define a general framework for knowledge discovery in urban feature analysis and enable the usage of GIS and data mining as complementary applications in urban feature analysis.

summary	The virtual reconstruction of the archeological site of Madinat al-Zahra. in Córdoba (Spain) has permitted a new approach to the study and comprehension of this palatine city as well as to the typologies of Islamic architecture in Al-Andalus during the 10th century. Starting from fieldwork and from a photogrammetric survey of the site, the digital model has become a highly qualified tool in the research process. Through virtual navigation, it allows to learn new aspects about spatial configuration of this characteristic constructions that configure the basis for the development of further architectures during the following centuries. Furthermore, being conscious that knowledge is basic for cultural heritage preservation, this 3D reconstruction model is an important instrument for general dissemination and for implementing a visit to this significant case of Islamic architecture in Spain.

title	LOS "SPIROSPACES"
source	Proceedings of the Fourth International Conference of Mathematics & Design, Special Edition of the Journal of Mathematics & Design, Volume 4, No.1, pp. 179-187.
summary	This paper deals with “Spirospaces”. These are a conversion to the third dimension of the two dimensional geometric entities called “Spirolaterals”. Abelson, Harold, diSessa and Andera (1968) gave the first rules concerning Spirolaterals. To obtain a Spirolateral from a set of straight lines, the first of them must be one unit long and the following must be incremented one unit at each step, at the same time that they turn in a constant direction. Odds (1973) establish the variation of the rotation direction, either to the left or the right. However, he did not give a mathematical relation able to calculate open Spirolaterals. Krawczyk (2001) developed a computer program that generates Spirolaterals following the method suggested by Abelson. These are Spirolaterals obtained by enumeration without a predictive mathematical formula. Krawczyc went farther proposing Spirolaterals based in curved lines. He pointed out that there are a variety of spirolateral forms that have architectural potentiality. Following this, the architectural potentiality of Spirolaterals is the basis of this paper. To take advantage of that potentiality a computer program was implemented to generate spatial configurations based in Spirolaterals. When a third dimension is given to the Spirolaterals they become Spirospaces. These new entities need spatial and design parameters to be useful for architectural purposes. Barrionuevo and Borsetti (2001) gave results about that work establishing the concept of Spirospaces. The aim of this paper is to describe a work directed to improve rules and procedures concerning Spirospaces. It is expected that these procedures governed by the proposed rules can be employed as tools during the early steps in the architectural design process. In this work some aspects concerning Spirospaces are considered. First, Spirolaterals are presented as the predecessors of Spirospaces. Second, Spirospaces are defined, together with their structural parameters. Architectural modeling is studied at the light of two special elements of the Spirospaces: Interstitial spaces and Object spaces. Next, a computer program is presented as the appropriate tool to model configurations having architectural potentiality. Finally, the results obtained running the computer program are analyzed to determine their possible use as architectural forms. Several graphic illustrations are presented showing steps going from the exploration of spatial alternatives to the selection of a specific configuration to be developed. It is expected that the described computer program could be employed as a design aid tool. As the operation of the program generates a variety of spaces able to dwell architectural objects, it eases the search of configurations suitable to specific functions. The results obtained have the possibility of being exported to computer graphic applications able to add materials, lights and cameras.

summary	This research was focused on visualizing new housing model and its customization based on people’s option as part of implementing community-based development principle. There are two significant research findings that are discussed in this paper that will be basis for developing a user-friendlier digital model as part of longterm research in visualizing whole resettlement process. The role of local person who is authorized to handle the model and to customize it to other inhabitants in the resettlement area is very essential in order to achieve the maximum versatility of the model. Another significant finding is potential of VRML model as information nodes for other digital modeling alternatives in an integrated information system for urban revitalization project.

summary	This paper presents a study in digital design and manufacturing of shells, which are material-efficient systems that generate their load-bearing capacity through curvature. Their complex shapes are challenging to build, and the few current shell projects employ the same shape repetitively in order to reduce the cost of concrete formwork. Can digital design and manufacturing technology make these systems suitable for the needs of the 21st century? The research developed new digitally-driven fabrication processes for Wood-Foam Sandwich Shells and Ferrocement-Concrete Sandwich Shells. These are partially pre-fabricated in order to allow for the application of Computer-Numerically Controlled (CNC) technology. Sandwich systems offer advantages for the digitally-enabled construction of shells, while at the same time improving their structural and thermal performance. The research defines design and manufacturing processes that reduce the need for repetition in order to save costs. Wood-Foam Sandwich shells are made by laminating wood-strips over a CNC-milled foam mold that eventually becomes the structural sandwich core. For Ferrocement-Concrete sandwich shells, a two-stage process is presented: pre-fabricated ferrocement panels become the permanent formwork for a cast-in-place concrete shell. The design and engineering process is facilitated through the use of parametric solid modeling environments. Modeling macros and integrated Finite-Element Analysis tools streamline the design process. Accuracy in fabrication is maintained by using CNC techniques for the majority of the shaping processes. The digital design and manufacturing parameters for each process are verified through design and fabrication studies that include prototypes, mockups and physical scale models.

summary	This paper presents the observations of a design studio for undergraduates that adopted a hands-on, experiential approach where students combined both digital modeling and full-scale construction in their design process. The studio was designed as team-based to encourage peer learning and collaboration in design. The students used multiple media and engaged in tactile experience and through the process discovered by themselves the issues of translating digital design into full-scale construction and achieved a better understanding of construction, scale and materiality.

summary	The direct and rapid connections between scripting, modeling and prototyping allow for investigations of computation in fabrication. The manipulation of planar materials with two-dimensional CNC cuts can easily create complex and varied forms, volumes, and surfaces. However, the bulk of research on folding using CNC fabrication tools is focused upon surfaces, self-supporting walls and shell structures, which do not integrate well into more conventional building construction models.This paper attempts to explain the potential for using folding methodologies to develop structural members through a design-build process. Conventional building practice consists of the assembly of off-the-shelf parts. Many times, the plinth, skeleton, and skin are independently designed and fabricated, integrating multiple industries. Using this method of construction as an operative status quo, this investigation focused on a single structural component: the truss. A truss is defined as: “A triangulated arrangement of structural members that reduces nonaxial external forces to a set of axial forces in its members.” (Allen and Iano 2004)Using folding methodologies and sheet steel to create a truss, this design investigation employed a recyclable and prolific building material to redefine the fabrication of a conventional structural member. The potential for using digital design and two-dimensional CNC fabrication tools in the design of a foldable truss from sheet steel is viable in the creation of a flat-packed, minimal waste structural member that can adapt to a variety of aesthetic and structural conditions. Applying new methods to a component of the conventional ‘kit of parts’ allowed for a novel investigation that recombines zero waste goals, flat-packing potential, structural expression and computational processes.
