title	Creation and editing of artifacts’ models by Generative Projects

summary	In this paper we propose an aiding system for the creation of models of artifacts which is based on a methodology that has its foundations in a concept that we call generative projects. This methodology has been defined separating the design paradigm of the designer from the computational model, defined in order to implement the system that support the designer in the design process, and from the graphical engine of the specific rendering system, chosen for the visualization of the generated artifact. In this work we defined an user interface that assists the designer during the design process, translates the result of the design into the underlying computational model and carries out the access to the rendering system in a transparent way. The experimentation of the system was conducted on various artifacts domains, as jewels, glasses, lamps, cutlery, wireless headphones, aerosols, pots and plans.

title	Spatializing the Internet: new types of hybrid mobile communication environments and their impact on spatial design within the urban context
doi	https://doi.org/10.52842/conf.ecaade.2006.160
source	Communicating Space(s) [24th eCAADe Conference Proceedings / ISBN 0-9541183-5-9] Volos (Greece) 6-9 September 2006, pp. 160-167
summary	This paper aims at investigating the emergence of new forms of communication environments, supported by the integration of new mobile and locative media technologies and the impact that the implementation of these systems may have on mediated communication within the urban context. The paper discusses the technologies supporting such multi-user systems (interactive graphical interfaces for mobile devices and locative media) and investigates the experience of interacting with such systems from a user’s perspective. It focuses on such systems accessed via interfaces, which have a spatial character and which are supported by different output devices, ultimately affording a hybrid (synthetic & physical) spatial experience. Communication is tied to places and places to communication. Consequently, these emerging types of communication may lead revolutionary new ways of social interaction and inhabiting urban space. With the emergence of these ICT systems, the city may again become a social arena and this development certainly calls for reconsidering the way in which we conceptualize and design urban environments.

title	Entornos Virtuales y su interconectividad en la WEB para la planificación urbana [Virtual Environments and their Interconnectivity in the Web for the Urban Planning]
source	SIGraDi 2006 - [Proceedings of the 10th Iberoamerican Congress of Digital Graphics] Santiago de Chile - Chile 21-23 November 2006, pp. 350-354
summary	Virtual Environments and their Interconnectivity in the Web for the Urban Planning. This work presents the creation of virtual environments based on the urban space of the Plaza Baralt in Maracaibo, Venezuela; in defined historical moments as study scenarios, using autonomous virtual agents. The selection of the scenarios is based in the analysis of the place in the present, and the study of multimedia material of the period 1920-2006. The main objective is developing virtual environments, incorporating the interconnectivity in the Web into a multi-user system, for the urban planning. Methodologically, it's divided into the following phases: 1) Data search; 2) Study of the social, cultural, religious and economical activities of the square; 3) Analysis of the urban space; 4) Virtual reconstruction of the scenarios in the present and in the period between 1900 - 1927; 5) VRML exporting ; 6) Characters' animation; 7) Integration of the models into a multi-user system; and 8) Web event for the presentation of the results.

summary	Airspace Tokyo is designed to establish a screened buffer zone - a thin, super-compact artificial “yard” that protects the building’s occupants from the pressing context of the dense urban environment outside. The new white, minimalist four-story building, designed by a Tokyo architect, is a stacked four unit multi-family dwelling with a garage and two large professional photography studios for lease on its ground floor. Located in the Ota-ku area of the city, the site was previously occupied by the owner with a sprawling residence that was wrapped by a layer of dense vegetation, and was unique in a city where open space is rare amidst the high demand for built space. Since the entire site is to now be razed to accommodate construction for the new and much larger development, the design intention for the screen is to invent an architectural system that performs with similar attributes to the demolished green strip and creates an atmospheric zone of protection. In effect, the demolished two meters of setback width of open ground space is now to be reduced into a new zone with a width of only 20 cm.

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	Approach to Design Behavioural Models for Traffic Network Users - Choice of transport mode
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. 151-166
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.

title	Context Aware Paper-Based Review Instrument A Tangible User Interface for Architecture Design Review
doi	https://doi.org/10.52842/conf.acadia.2006.317
source	Synthetic Landscapes [Proceedings of the 25th Annual Conference of the Association for Computer-Aided Design in Architecture] pp. 317-327
summary	We describe the design and implementation of a prototype computer-supported collaborative work (CSCW) environment for review of architectural construction documents. This environment utilizes a novel plain-paper tangible interface that supports shared activity such as review of construction documents using an “over the shoulder” computational assistant called CAPRI.Despite the increasing use of computers, work in most architecture firms still largely revolves around paper drawings. Architects structure their work around paper instead of digital representations for reasons of legal liability and tradition, as well as technical limitations. While hardcopy is intuitive, dense, and easy to access, it lacks direct connection to the wide range of design knowledge increasingly available in interactive design environments. This lack is felt most acutely during design review processes, when the designer or reviewer is often called upon to consult and consider holistically a variety of supporting (backing) documents, a task which requires focused attention and a good memory, if errors are to be avoided.Our prototype system enables multiple reviewers to interact equally with a paper construction document using a tangible interface to query detail and backing data from a project knowledge base. We believe this will decrease the reviewer’s cognitive load by bringing design data to them in a contextual and timely way. In doing so, we believe errors will be caught sooner and mistakes reduced.

title	Supporting Collective Intelligence for Design in Virtual Worlds: A Case Study of the Lego Universe
source	Computer Aided Architectural Design Futures 2011 [Proceedings of the 14th International Conference on Computer Aided Architectural Design Futures / ISBN 9782874561429] Liege (Belgium) 4-8 July 2011, pp. 637-652.
summary	Virtual worlds are multi-faceted technologies. Facets of virtual worlds include graphical simulation tools, communication, design and modelling tools, artificial intelligence, network structure, persistent object-oriented infrastructure, economy, governance and user presence and interaction. Recent studies (Merrick et al., 2010) and applications (Rosenman et al., 2006; Maher et al., 2006) have shown that the combination of design, modelling and communication tools, and artificial intelligence in virtual worlds makes them suitable platforms for supporting collaborative design, including human-human collaboration and human-computer co-creativity. Virtual worlds are also coming to be recognised as a platform for collective intelligence (Levy, 1997), a form of group intelligence that emerges from collaboration and competition among large numbers of individuals. Because of the close relationship between design, communication and virtual world technologies, there appears a strong possibility of using virtual worlds to harness collective intelligence for supporting upcoming ‚Äúdesign challenges on a much larger scale as we become an increasingly global and technological society‚Äù (Maher et al, 2010), beyond the current support for small-scale collaborative design teams. Collaborative design is relatively well studied and is characterised by small-scale, carefully structured design teams, usually comprising design professionals with a good understanding of the design task at hand. All team members are generally motivated and have the skills required to structure the shared solution space and to complete the design task. In contrast, collective design (Maher et al, 2010) is characterised by a very large number of participants ranging from professional designers to design novices, who may need to be motivated to participate, whose contributions may not be directly utilised for design purposes, and who may need to learn some or all of the skills required to complete the task. Thus the facets of virtual worlds required to support collective design differ from those required to support collaborative design. Specifically, in addition to design, communication and artificial intelligence tools, various interpretive, mapping and educational tools together with appropriate motivational and reward systems may be required to inform, teach and motivate virtual world users to contribute and direct their inputs to desired design purposes. Many of these world facets are well understood by computer game developers, as level systems, quests or plot and achievement/reward systems. This suggests the possibility of drawing on or adapting computer gaming technologies as a basis for harnessing collective intelligence in design. Existing virtual worlds that permit open-ended design ‚Äì such as Second Life and There ‚Äì are not specifically game worlds as they do not have extensive level, quest and reward systems in the same way as game worlds like World of Warcraft or Ultima Online. As such, while Second Life and There demonstrate emergent design, they do not have the game-specific facets that focus users towards solving specific problems required for harnessing collective intelligence. However, a new massively multiplayer virtual world is soon to be released that combines open-ended design tools with levels, quests and achievement systems. This world is called Lego Universe (www.legouniverse.com). This paper presents technology spaces for the facets of virtual worlds that can contribute to the support of collective intelligence in design, including design and modelling tools, communication tools, artificial intelligence, level system, motivation, governance and other related facets. We discuss how these facets support the design, communication, motivational and educational requirements of collective intelligence applications. The paper concludes with a case study of Lego Universe, with reference to the technology spaces defined above. We evaluate the potential of this or similar tools to move design beyond the individual and small-scale design teams to harness large-scale collective intelligence. We also consider the types of design tasks that might best be addressed in this manner.

title	Sensitive Voxel - A reactive tangible surface
source	Computer Aided Architectural Design Futures 2011 [Proceedings of the 14th International Conference on Computer Aided Architectural Design Futures / ISBN 9782874561429] Liege (Belgium) 4-8 July 2011, pp. 525-538.
summary	Haptic and tactile sensations, the active or passive exploration of our built surroundings through our sense of touch, give us a direct feeling and detailed information of space, a sense of architecture (Pallasmaa 2005). This paper presents the prototype of a reactive surface system, which focuses its output on the sense of touch. It explains how touch sensations influence the perception of architecture and discusses potential applications that might arise from such systems in the future. A growing number of projects demonstrate the strong impact of interaction design on the human senses and perception. They offer new ways of sensing and experiencing architectural space. But the majority of these interaction concepts focus on visual and auditory output-effects. The sense of touch is typically used as an input generator, but neglected as as a potential receiver of stimuli. With all the possibilities of sensors and micro-devices available nowadays, there is no longer a technical reason for this. It is possible to explore a much wider range of sense responding projects, to broaden the horizon of sensitive interaction concepts (Bullivant 2006). What if the surfaces of our surroundings can actively change the way it feels to touch them? What if things like walls and furniture get the ability to interactively respond to our touch? What new dimensions of communication and esthetic experience will open up when we conceive of tangibility in this bi-directional way? This paper presents a prototype system aimed at exploring these very questions. The prototype consists of a grid of tangible embedded cells, each one combining three kinds of actuators to produce divergent touch stimuli. All cells can be individually controlled from an interactive computer program. By providing a layering of different combinations and impulse intensities, the grid structure enables altering patterns of actuation. Thus it can be employed to explore a sort of individual touch aesthetic, for which - in order to differentiate it from established types of aesthetic experiences - we have created the term 'Euhaptics' (from the Greek ŒµœÖ = good and Œ¨œÄœÑœâ = touch, finger). The possibility to mix a wide range of actuators leads to blending options of touch stimuli. The sense of touch has an expanded perception- spectrum, which can be exploited by this technically embedded superposition. The juxtaposed arrangement of identical multilayered cell-units offers blending and pattern effects of different touch-stimuli. It reveals an augmented form of interaction with surfaces and interactive material structures. The combination of impulses does not need to be fixed a priori; it can be adjusted during the process of use. Thus the sensation of touch can be made personally unique in its qualities. The application on architectural shapes and surfaces allows the user to feel the sensations in a holistic manner ‚Äì potentially on the entire body. Hence the various dimensions of touch phenomena on the skin can be explored through empirical investigations by the prototype construction. The prototype system presented in the paper is limited in size and resolution, but its functionality suggests various directions of further development. In architectural applications, this new form of overlay may lead to create augmented environments that let inhabitants experience multimodal touch sensations. By interactively controlling the sensual patterns, such environments could get a unique ‚Äútouch‚Äù for every person that inhabit them. But there may be further applications that go beyond the interactive configuration of comfort, possibly opening up new forms of communication for handicapped people or applications in medical and therapeutic fields (Grunwald 2001). The well-known influence of touch- sensations on human psychological processes and moreover their bodily implications suggest that there is a wide scope of beneficial utilisations yet to be investigated.

title	Interactive Parametric Design and the Role of Light in Byzantine Churches
doi	https://doi.org/10.52842/conf.ecaade.2006.798
source	Communicating Space(s) [24th eCAADe Conference Proceedings / ISBN 0-9541183-5-9] Volos (Greece) 6-9 September 2006, pp. 798-803
summary	Byzantine church design depended heavily on natural light which was used for evocative purposes. The orientation of the main axis of the church, the form of the apse and the location and size of its windows are affected by the need for sunlight to shine at the altar on a desired time and for a certain duration. Until now the process of accurately taking account of all the above parameters has been rather difficult and tedious. This paper illustrates the use of digital tools both for the analysis of the geometry of existing apse designs and the parametric generation of new ones. A sophisticated computer program was used to calculate sun angles during the Byzantine period incorporating calendar changes. In addition, Bentley System’s Generative Components software was used to construct a parametric model that allows the user to define the geometric conditions and parameters of the apse. The software would then iterate through multiple solutions to satisfy the desired conditions as well as allow the user to change the conditions at will. The tools were used to discover the geometry of the apse of the Byzantine church of Hagia Sophia in Constantinople and to analyze the apse of the Post-Byzantine church of the Xeropotamou monastery on Mount Athos in Greece. The paper concludes with a discussion of the role of parametric tools for architectural analysis and the generation of possible design solutions.

title	A 3D, interactive, multilayered, web-enabled model as a tool for multiple sets of end user groups: A case study and end user analysis
source	SIGraDi 2006 - [Proceedings of the 10th Iberoamerican Congress of Digital Graphics] Santiago de Chile - Chile 21-23 November 2006, pp. 392-396
summary	This research undertakes a case study involving focus groups of potential end users, to identify how a successful digital tool could be created using new and emerging technologies, to accommodate the multiple needs of these end users. 2005 saw the completion of a research paper, which proposed that a single, 3 dimensional digital model of a city forming a core for many different information systems, is a better approach to the needs of the city than many individual models optimised for each information system. The case for the single 3D model was evaluated through the research, development, delivery and analysis of a prototype 3 Dimensional model of Wellington City, New Zealand, presenting different ‘views’ of information in Wellington: a rendered visualisation in an animated “walkthrough”; the impact of planning constraints on daylight; interactive “plots” of property values. The development and delivery of the prototype model was analysed in regards to how complex, costly and time consuming it may be to exploit one base model for several purposes; and also therefore how beneficial, affordable and potentially successful a single model may be. The prototype model was created to test the idea, and therefore provided conclusions based on a limited feasibility analysis - with four potential information layers modelled and two potential delivery methods tested. The prototype model and user analysis results were presented in a research report that suggested further research and development of a single model could be very beneficial: Positive feedback from potential end users and data providers, and examples of potential data mining opportunities forming the basis of the need for continued research. 2006 sees the research continue as an 18 month research project in conjunction with an industry partner, Terralink International, (http://www.terralink.co.nz/). Terralink International Limited provides GIS and mapping solutions which according to their web site: “enable better business management.” The company maintains a national resource of “imagery, cartography, and spatial databases” and provides consultancy services linking these to company databases through GIS systems. The research investigates the potential for 3 dimensional, interactive, multilayered models to enhance delivery of information to multiple end user groups. The research method uses functional prototypes in end-user focus group workshops. These workshops, consisting of a combination of presentations, hands on interactive examples, group discussions, and individual feedback surveys, aim to establish how a tool might best be developed to communicate to a wide range of end users. The means of delivery whether a stand alone tool or web-based is a key element of the user group workshop assessment process. Note: The submission of the prototype tool (via video or interactive media) would greatly increase the effectiveness of the research presentation. Ability to include such media would be greatly appreciated.

title	The Hylomorphic Project
doi	https://doi.org/10.52842/conf.acadia.2006.536
source	Synthetic Landscapes [Proceedings of the 25th Annual Conference of the Association for Computer-Aided Design in Architecture] pp. 536-537
summary	The Hylomorphic Project is a complex canopy structure, genetically evolved as a vital entity that reacts to changing data streams while configuring the architectural form. For the Hylomorphic Project, Open Source Architecture (OSA) together with structural engineer Prof. Kristina Shea and Marina Gourtovaia of Cambridge University (UK) developed genetic algorithms. Performs in eifForm software, an experimental computer-aided design system for structural synthesis, the algorithm is based in computational environments as a methodology for form finding and material expression that goes beyond the formal articulation of the computational procedure. This procedure simulates a topological condition of natural form evolution that can be consolidated according to innumerable trajectories. Seeking dynamic, flexible and continuous evolution procedures, the software provides the required conditions for this type of the design as it consists of a computational core, which is written in C, a fast low-level compiled language. The modules providing interactive access to the core and the graphical user interface (GUI), a high-level scripting language written in Python, allow for easy customization of the software according to a design task in hand.

summary	In the Architecture Engineering and Construction (AEC) sector, cooperation between actors is essential for projects success. During the building construction activity, organization is both hierarchical and adhocratic. Decision assistance tools have to integrate these heterogeneous parameters. The proposition described here consists of the design of a coordination assistance tool providing synthetic indicators on the statement of the activity and also allowing the user to navigate in the cooperative context through multiple views. This proposition is based on a model architecture allowing us to manage cooperative context information and its visualization.

title	The potential of Virtual Environments as contexts for Communication
doi	https://doi.org/10.52842/conf.ecaade.2006.750
source	Communicating Space(s) [24th eCAADe Conference Proceedings / ISBN 0-9541183-5-9] Volos (Greece) 6-9 September 2006, pp. 750-753
summary	This paper documents a study done considering Virtual Reality (VR) as a spatial representational context which supports communication. It aims to identify whether VR could be considered as a communication medium, a tool that could be used for the successful transmission of information and messages, as well as the future form, content and use of it. That is, how does communication occur in a Virtual Environment (VE), by taking into account its visual properties and spatial parameters and under which conditions communication messages are conducted via VR systems, deriving from the one part (sender) and concluding to the other (receiver). The methods selected for this study involve observation and use of questionnaires at the end of each session. An already existing Internet-based online multi-user virtual environment has been chosen as the context where this survey will be carried out, that is the site Active Worlds, http://www.activeworlds.com, which can be accessed very easy to any computer user, in a desktop form. Firstly, we investigated the time needed, depending on the complexity per case, for a user of the VR application to get acquainted with the system. We were interested to know if the meaning that we would like to communicate had either remained the same through all the time of the experience or had been “modified” in a certain way and if so, for what reason. Another issue that was examined was the way in which the spatial context in a specific VE affects the way communication occurs. The framework of the application may influence the way the person receives a message, for example by making assumptions and references that he would not have made in a different environment- outside VR. After the end of the experience, the user was invited to describe his/ her impressions, with the communication factor being stressed, that is to mean if and at what extent VR can be characterized as a communication medium, as it is mentioned above, even for limited information and messages in general.

summary	As the title suggests, this paper makes an attempt to provide a factual analysis and synthesis of the activities that the Tex-Mex Virtual Design Studio, and later the Las Americas Virtual Design Studio, have been implementing since September of 1996, The objective of this attempt is to provide a framework for the formulation of a new conceptual and instrumental profile for future implementations of our virtual design studios. With such a purpose the paper outlines the importance of virtual design studios in the framework of opening design education to distance education methodologies and argues in favor of their further utilization for addressing issues of globalization in architecture and design education. This argument is followed by a quick description of current practices within the Las Americas Virtual Design Studio and sets the stage for a detailed description of how multi-user interactive environments may further support interaction within virtual design studios.

summary	In this research, we implemented the 3D interactive interface for city navigation, and used an infrared 3D tracker as an interaction input device in VR CAVE. The design of 3D interface was evaluated by cognitive approach while navigating with a handheld sensor in the VR CAVE. According to the results of cognitive experiment, some revised design guidelines are proposed for further 3D navigation interface.

title	BALANCING FREEDOM AND CONTROL FOR WALKTHROUGH IN VIRTUAL ARCHITECTURE: A Smart and Comprehensive Navigation System
doi	https://doi.org/10.52842/conf.caadria.2006.x.b2g
source	CAADRIA 2006 [Proceedings of the 11th International Conference on Computer Aided Architectural Design Research in Asia] Kumamoto (Japan) March 30th - April 2nd 2006, 387-396
summary	This paper presents a new navigation system that integrates a perspective view for walkthrough and an interactive map for path planning. The interactive map allows users to draw paths and improves path planning by employing either a 3D aerial view that enables users to zoom and examine or a 2D smart map that possesses knowledge about the usability of design elements in the environments. Path control is merged into users' interactive walkthrough seamlessly and intuitively to achieve a balance of freedom and control. Further more, the paths with all related information can be saved in real-time over the Internet by a user and can be loaded and replayed later by other users. Two case studies demonstrate the application of this system in Virtual Architecture.

title	Feature clusters for online recognition of graphic units in drawings
doi	https://doi.org/10.52842/conf.ecaade.2006.106
source	Communicating Space(s) [24th eCAADe Conference Proceedings / ISBN 0-9541183-5-9] Volos (Greece) 6-9 September 2006, pp. 106-112
summary	Automated recognition of sketch drawings can provide the means for a natural interface between the designer and a design support system. Sketch drawing recognition is knowledge-intensive in the sense that the system must know what to look for in a drawing. In earlier work, we identified 24 different types of representations, termed graphic units. For recognition of graphic units we combine a multi-agent approach and online recognition. Each agent is specialised for one graphic unit. It continuously parses the online input stream for stroke features that fall within its scope. When an agent-specific threshold is reached, the agent puts a claim. Each agent has a specific cluster of features that can be viewed as distributed over a decision tree. The activation pattern of feature clusters over the decision tree is an indication which graphic unit is likely to be identified by the system. In this paper, we present the exhaustive set of features for agents and a binary decision tree over which the features are distributed.

title	Diretrizez Geométricas de Auxílio ao Processo de Projeto de Edifícios Residenciais [Geometrical Guidelines to Aid the Design of Floor Plants of Residential Buildings]
source	SIGraDi 2006 - [Proceedings of the 10th Iberoamerican Congress of Digital Graphics] Santiago de Chile - Chile 21-23 November 2006, pp. 243-247
summary	This paper discusses the basic principles of a geometric method to aid the design process of residential buildings. It makes part of the initial phases of a research whose aim is to develop a computer system to aid the sketching and evaluation of floor plant design of multi-storied residential buildings. The fundamental idea of the research is the existence of some basic patterns of floor plants that reflect the designer’s mental models in this category of building. The models are regarding the usage of the space such as forms and dimensions, the elements for the circulation and the external skins. During the design process, architects work on each one of these models to generate the sketches of the floor plant layout. Generally, the layout of an apartment in multi-storied buildings depends basically on the internal dynamics of the users without the complex relationship with the neighborhood environment as in the case of houses. In this way, it would be easier to identify, to organize and to associate the mental models of multi-storied buildings on geometric basis, which, in their turns, might be effectively used as inputs for the layout planning of new design. By applying the geometric basis, the architects may reduce the universe of feasible alternatives into a small group of heuristic solutions that can be described by using few simple guidelines. In addition to this, the geometric bases of the existing buildings might be used to build a knowledge-based system to aid the architectural design. The objective of this paper is to show some initial results of the research obtained from a survey and the case studies of form, dimensions and topology of existing buildings. To limit the scope of the discussion, only residential buildings with two to three bedrooms are considered. At first, a survey of plants of residential buildings with two and three bedrooms, in Brazil, is carried out. In the next step, the dimensions, shape, external skin perimeter, circulation system and accessibility are analyzed. Finally, typical topologies of the building are investigated.

title	Sensor-based Aware Environment
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 provides an overview of the requirements for a computational model of a Sensor-Based Aware Environment (SBAE) that integrates sensor technologies with the Building Information Modelling (BIM) in order to sense ambient and physical aspects of the built environment. Wireless sensors sense ambient data of a built environment, process, and communicate these data through an ad-hoc wireless network. The BIM, on the other hand, is based on International Foundation Classes (IFCs) and contains data about the physical infrastructure (i.e. Walls, Windows, doors) and abstract entities (i.e. Spaces, Relationships) and relationships between those entities. Therefore, the proposed computational model could sense real time data that are related to the as-built information model allowing for holistic building state information.
