title	A survey of computer software for the urban designprocess
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	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	As a couple of years ago the use of computers slowly entered studios of architecture, the development of operating systems actually enables everybody to control even bigger networks within studios or offices. Recently these local networks started to get networked themselves. Interactions between local design partners involve a large variety of problems• different CAD-systems• different versions of the same CAD-system• different methods of transfer• different security ideas• different levels of technical knowledge In the course of extension to a global level these problems in the first approach have been growing dramatically, involving additionally language and mentality problems. But in the outcome the exchange of documents and ideas improves in speed, quality and accuracy or this will at least happen in the near future.Global networking offers a great challenge, we have to give this matter a big deal of efforts to earn the values and results, which may be achieved.

summary	This study is placed on the research line of Pedagogical practice and formation of the educator, which theme is related to learning in virtual worlds. The article presents and discusses some aspects of the process of approaching subjects (teachers) to a Virtual World, at a first moment, in a level of exploration, experimentation, interaction as a user, and, at a second moment as a creator, an author of a Virtual World, AWSINOS. The present study takes part of a exploratory/experimental research of qualitative nature that looks for the creation of virtual worlds for the continued qualification online and focuses on the investigation of socio-cognitive behaviors of subjects during their organization as a group and during the activity of building and using these worlds.

title	Simulation of Micro Pedestrian Behaviour in Shopping Streets
source	Van Leeuwen, J.P. and H.J.P. Timmermans (eds.) 2006, Progress in Design & Decision Support Systems in Architecture and Urban Planning, Eindhoven: Eindhoven University of Technology, ISBN-10: 90-386-1756-9, ISBN-13: 978-90-386-1756-5, p. 101-116
summary	Over the years, scholars have developed various models of pedestrian movement. These models can be used to assess the effects of detailed design decisions or to predict pedestrian behaviour under conditions of crowding. To date, not much attention has been paid to pedestrians' shopping behaviour at the micro level. Therefore, the main purpose of this project is to test a model that aims at simulating micro pedestrian behaviour in shopping streets, including entering shops. The model assumes a detailed network of links to represent the structure of street segments and entrances to the shops. The basic principle underlying the model is that a pedestrian moves from one link in the network to another, adjacent link. In fact, a pedestrian enters a segment at one side, heading for the other side of the segment. However, a pedestrian might enter the segment by leaving a shop as well. Then, the pedestrian might be heading for either side of the segment. While transferring from the current link to the next link, the pedestrian will be attracted by the shops along both sides of the street. The study area is Antwerp's main shopping street. During a one-week workshop in July 2004, students observed pedestrian movement in this shopping street. An inventory of some physical characteristics of the shopping street was made and pedestrians were tracked through two separate segments of the shopping street. In total, 334 pedestrians were tracked. A conventional multinomial logit model is used to simulate pedestrians' micro behaviour. The process of consecutively selecting links continues until the pedestrian has reached one of the terminal links or a shop. The model performs very well. Simulated routes were used to assess the validity of the model. Observed and simulated link loading correspond fairly well, however, the model seems to slightly mispredict the attraction of a number of shops.

title	The DXI Experience. Ten Years of Design Visualization Developments in an Educational Laboratory Context

summary	Design visualisation is an essential aspect of virtually every form of design enquiry. The effects of potential environmental interventions may be simulated in order to gain the types of insights, which cannot be acquired easily from two-dimensional notations. Three-dimensional representations may be generated for very different reasons. The most direct form of design imaging is traditionally for the benefit of the designer him/herself, in order to test whether the working concepts offer fitting solutions to the complex array of design conditions such as context, programme and feasibility. Alternately, images may be generated for the benefit of communication, in order to offer insights into the expected workings of a particular proposal (possibly including alternatives). This may lead to greater understanding and possibly to reaching consensus amongst different ‘actors’ involved in the design and realisation process. In many cases the results of such visualisation studies contribute to ‘bridging the gap’ between the professionals and other parties involved more indirectly in design decision-making or the appraisal of the proposals. Designers can use distinctly different methods when going about such imaging procedures. Their choices for particular techniques may depend on their familiarity or the availability of certain media devices. Being confronted with new modelling and/or visualisation instruments can stimulate the interest in fresh approaches. In this respect, the design education environment can play an important role in not only teaching ‘proven’ applications to future designers, but also in creating a platform for the active development of innovative approaches to the design visualisation practices: education as a ‘laboratory’ for new insights and potentially a ‘breeding ground’ for the extension of the designer’s instrumentation. This contribution documents the experiences gained in some ten years within an educational application, involving active use of design driven media applications. The emphasis lies on the evolvement of techniques for eye-level imaging, whereby use can be made of different types of models: physical scale models as well as digital, virtual models. Changing attitudes towards dynamic and serial vision are considered, whereby storyboard approaches on the level of integral presentation are considered. By analysing a selection of cases and their underlying approaches an indication is given of the changing attitudes and combinations of multimedia techniques, which offer opportunities to design visualisation and communication.

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	Building a Synthetic Cognizer
source	Design Computation Cognition conference 2004, MIT
summary	Understanding ‘space’ as a structured and dynamic system can provide us with insight into the central concept in the architectural discourse that so far has proven to withstand theoretical framing (McLuhan 1964). The basis for this theoretical assumption is that space is not a void left by solid matter but instead an emergent quality of action and interaction between individuals and groups with a physical environment (Hillier 1996). In this way it can be described as a parallel distributed system, a self-organising entity. Extrapolating from Luhmann’s theory of social systems (Luhmann 1984), a spatial system is autonomous from its progenitors, people, but remains intangible to a human observer due to its abstract nature and therefore has to be analysed by computed entities, synthetic cognisers, with the capacity to perceive. This poster shows an attempt to use another complex system, a distributed connected algorithm based on Kohonen’s self-organising feature maps – SOM (Kohonen 1997), as a “perceptual aid” for creating geometric mappings of these spatial systems that will shed light on our understanding of space by not representing space through our usual mechanics but by constructing artificial spatial cognisers with abilities to make spatial representations of their own. This allows us to be shown novel representations that can help us to see new differences and similarities in spatial configurations.

title	Modularity and Flexibility at the Small Scale: Evolving Continuous Material Variation with Stereolithography

summary	In this paper, we introduce a technique by which the internal material properties of an object can be optimised at a microstructural level (5x10-5m) to counteract the forces that are applied to it. These can then be fabricated using the rapid prototyping method of stereolithography. The proposed technique is analogous to principles of mass customization and takes advantage of a flexible module to create complex structures in a manner that is computationally efficient and effective. The process is two-staged, in which a genetic algorithm evolves the topology of the microstructure and a second algorithm incorporating Finite Element Analysis then optimises the geometry. The examples shown are designed specifically for the fabrication technique, but the method and general principles are applicable to structural problems at any scale.

summary	In this research, I propose a case-based simulation method for experimenting with a set of models aimed at analyzing the behavior of a dynamic system. Owing to the assistance of CBRWorks4 software, this idea is successfully tested and implemented on the Internet. A set of evacuation simulations, which model complex human behavior in a building in certain emergency situations, leads to some discoveries and conclusions.

title	Linking Analysis and Architectural Data: Why It's Harder than We Thought

summary	This paper considers high-level, architecturally oriented representations, like Building Information Models (BIMs), and examines the difficulty of integrating analyses with such representations. Structural analysis is selected as a sample analysis domain, and is examined by integrating a structural analysis into the test implementation of a program that utilizes architecturally oriented elements. A fundamental problem is found to be that architecturally oriented elements are inappropriate for structural analysis. Methods for sequentially analyzing architectural elements are discussed, but are found to be inadequate. Accurate analysis requires analyzing the entire structure at once using a representation specific to structural analysis. A method for generating a structural representation based on the architectural representation is discussed, but the process is not simple. The process is complicated by the fact that architectural elements and structural elements do not correspond in a one-to-one or even a one-to-many manner. An accurate structural representation may even require semi-fictitious elements not corresponding to actual physical components. These findings are believed to be true for other analysis domains, as well.

title	THE RIGHT STORY AT THE RIGHT TIME -- TOWARDS A TACIT KNOWLEDGE RESOURCE FOR (STUDENT) DESIGNERS
source	AI & Society, Issue: Online First, July 2004 [ISSN: 1435-5655 (Online)]
summary	In response to the lack of systematic study of architectural practice, the Building Stories methodology propounds storytelling as a vehicle for studying active cases, i.e., projects that are in the process of being designed and built. The story format provides a dense, compact way to deal with and communicate the complex reality of a real-world project, while respecting the interrelated nature of events, people and circumstances that shape its conception. With an eye to establishing a valuable knowledge resource of and for the profession, the paper explores how stories can be stored, organized and accessed so as to turn the growing story repository into a convenient instrument for students, educators and practitioners.

title	Digital Fabrication Production System Theory: Towards an Integrated Environment for Design and Production of Assemblies
source	SIGraDi 2008 - [Proceedings of the 12th Iberoamerican Congress of Digital Graphics] La Habana - Cuba 1-5 December 2008
summary	A Digital Fabrication Production System (DFPS) is a concept describing a set of processes, tools, and resources that will be able to produce an artifact according to a design, fast, cheap, and easy, independently of location. A DFPS project is a complex assembly of custom parts that is delivered by a network of fabrication and assembly processes. This network is called the value chain. The workflow concept of a DFPS is the following: begin design process with a custom geometric form; decompose it into constructible parts; send the part files for fabrication to various locations; transport all parts at the construction site at the right time; finally, assemble the final artifact. Conceptually it means that based on a well structured value chain we could build anything we want, at anyplace, at controllable cost and quality. The goals of a DFPS are the following: custom shapes, controllable lead time, controllable quality, controllable cost, easiness of fabrication, and easiness of assembly. Simply stated this means to build any form, anywhere, accurately, cheap, fast, and easy. Unfortunately, the reality with current Digital Fabrication (DF) projects is rather disappointing: They take more time than what was planned, they get more expensive than what was expected, they involve great risk and uncertainty, and finally they are too complex to plan, understand, and manage. Moreover, most of these problems are discovered during production when it is already late for correction. However, there is currently no systematic approach to evaluate difficulty of production of DF projects in Architecture. Most of current risk assessment methods are based on experience gathered from previous similar cases. But it is the premise of mass customization that projects can be radically different. Assembly incompatibilities are currently addressed by building physical mockups. But physical mockups cause a significant loss in both time and cost. All these problems suggest that an introduction of a DFPS for mass customization in architecture needs first an integrated theory of assembly and management control. Evaluating feasibility of a DF project has two main problems: first, how to evaluate assemblability of the design; second, how to evaluate performance of the value chain. Assemblability is a system’s structure problem, while performance is a system’s dynamics problem. Structure of systems has been studied in the field of Systems Engineering by Network Analysis methods such as the Design Structure Matrix (DSM) (Steward 1981), and the liaison graph (Whitney 2004), while dynamics of systems have been studied by System Dynamics (Forrester 1961). Can we define a formal method to evaluate the difficulty of production of an artifact if we know the artifact’s design and the production system’s structure? This paper formulates Attribute Process Methodology (APM); a method for assessing feasibility of a DFPS project that combines Network Analysis to evaluate assemblability of the design with System Dynamics to evaluate performance of the value chain.

title	Untimely Fabrications
doi	https://doi.org/10.52842/conf.acadia.2004.052
source	Fabrication: Examining the Digital Practice of Architecture [Proceedings of the 23rd Annual Conference of the Association for Computer Aided Design in Architecture and the 2004 Conference of the AIA Technology in Architectural Practice Knowledge Community / ISBN 0-9696665-2-7] Cambridge (Ontario) 8-14 November, 2004, 52-65
summary	The value of material in architectural practice is determined not by its character but by functional performance and economy. In early modernist thought, part of this motivation was to liberate construction from the ‘burden’ of aesthetic speculations and return it simply to the concerns of building. Any artistic agenda became embedded in the economic and productive processes of the project. Authenticity emerged out of the need to focus on the essentials and reject the superfluous. However, this demand for truth in materials has long since been compromised by the climatic requirements of building enclosure. Most contemporary practice in architecture is derived from principles of cladding where the ‘essential nature’ of a complex building requires concealment. The communication of the building is expressed in the refinement of the layers that make up the surface. This shift from the emphasis on making and the idea of ‘material’ in architecture, to one of perception and ‘materiality,’ has an important corporeal dimension that parallels the material aesthetic practices developed in art and sculpture in the 1960s. In this sense, Fabrication carries an ‘untimely’ dimension. This paper proposes to look at the work of a broad range of architects, both well-known and not so well-known, in light of these artistic-based approaches to materiality. Digital fabrication opens a new chapter on this debate and it remains to be seen how this economically useful approach to construction changes, once architects investigate the visual characteristics of materials and methods of fabrication.

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	Whether in splendid rural isolation or in an urban area, settlement and building structures always are exposed to the public. Questions as to the future design of our vital space basically always concern the public and thus call for a great deal of discussion. Launching a well-balanced debate between all those involved in the planning and design process requires clear exemplification of urban-spatial visions by means of simulation. A simulation device - called “City Simulator” - suited to conveying the multitude of spatial relations within the urban configuration and for developing urban-spatial ideas would fulfil such expectations. The complexity of the information required in this context can be coped with effectively by means of computer-aided simulation techniques focusing on digital city models. Thus the implementation of a “City Simulator” may be regarded as a decisive tool for the purpose. As those involved in the process normally consider themselves absolute novices within the context of complex planning processes, the simulator will to some extent act as a “translation machine”. This paper is based on a project proposal which has been submitted by the authors aimed at the acquisition of a “City Simulator” at Vienna University of Technology in the near future.

summary	3-D printers alter the speed, cost, complexity, and consistency with which physical architecture models can be crafted. If architects are to harness the unique abilities of this modeling process, it is necessary to find a complementary means of conceptualizing designs and generating the geometric data necessary for 3-D printing. This paper introduces a novel combination of 3-D printing and scripting through three examples of architectural surface models. In these examples, VBScript is used to write generative scripts for execution within the Rhinoceros modeling environment. The scripts produce digital geometric models which, in turn, are exported to a Z-Corp 3-D printer. The merits of this methodology are demonstrated, in one example, through models of an architectural surface composed of light-modulating conical components. The design intent in this example is a grid of responsive components which ride on a complex curved surface and steer toward a light. The written script is an explicit representation of this intention. Methods in the script use external parameters to generate a digital geometric model. The form of the subsequent printed model is calculated as a function of the initial parameters, two boundary splines and a vector indicating the orientation of the light. By varying these parameters, a set of design options can be generated and 3-D printed for comparison. The combination of scripting and 3-D printing allows complex design intentions to be managed in a concise, sharable format and modeled iteratively without manual intervention.

title	STRUCTURAL SKETCHER: A TOOL FOR SUPPORTING ARCHITECTS IN EARLY STAGES
source	PhD thesis, Technische Universiteit Eindhoven, The Netherlands
summary	Traditionally, architects use pen and paper for the early stages. Architects have great expertise in drawing, their use is simple and has low overhead, and a high precision is not required, and even counterproductive. The last decades many systems to support architects have been developed. These are primarily suited for the production of final technical drawings. Architects do not use them in the early phases, because they do not offer the freedom, speed, and ambiguity needed there. Nevertheless, the use of a computer could offer benefits, such as ease of modification and editing as well as higher level support. The aim of the project described in this thesis was to develop a computer-sketching tool to support architects in the early design stages.

title	An object oriented approach to simulating agent-based behavior
source	SIGraDi 2004 - [Proceedings of the 8th Iberoamerican Congress of Digital Graphics] Porte Alegre - Brasil 10-12 november 2004
summary	In this paper, we present an object-oriented approach for simulating agent-based egress behavior. The tool can be used when planners or designers need to assess the implications of their design or planning decisions. The tool is a web-based application that is being developed using standard protocols and technologies such as HTTP, HTML, and Java. It also demonstrates the effect of new building designs by simulating human evacuation behavior and relates the behavior of people. The existing models to describe the behavior of crowds usually deal with macroscopic variables like the average speed or the flow. Our aim is to model crowds as a malleable, moving masses, hoping that a more refined simulation might be achieved by considering each avatars behavior.

title	Urbamedia - Development of an urban database of fragments of some Argentinian and Latin-American cities using digital technology

summary	The proposal of "Urbamedia" is to undertake the development of 3D virtual and interactive models of historical areas of Latin-American cities. The selected zone is the "Mayo Avenue" including the "Mayo Square", an historical place of the city of Buenos Aires, Argentina; this project is financed by the National Agency of Scientific and Technological Development of Argentina and the University of Buenos Aires.We are presenting the first experimental model of the "Mayo Square" that has been developed at ABACUS, Department of Architecture & Building Aids Computer Unit, University of Strathclyde UK. combined with a system analysis of urban activities using the “Atlas.ti” CAQDAS software.This particular use of the “Atlas.ti” software is under experimental applications to this type of urban analysis procedures; allowed us the possibility to analysed a set of activities by means of graph theory as result of a series of interviews to the people working in the area. We are also looking to include historical areas of three cities: Mar del Plata, Rosario and Santa Fe (Argentina) and eventually other cities from Latin América as Rio de Janeiro and Habana.Due that ABACUS has a strong experience in city modelling plus the powerful software and hardware used there, we must develop a VRML customized menu to be adapted to our low cost PC equipment. The 3D model will be used mainly in urban design simulation procedures and the idea is to extend to other type of simulations of the environmental parameters.

summary	Recent developments in digital technologies and smart materials have created new opportunities and are suggesting significant changes in the way we design and build architecture. Traditionally, however, there has always been a gap between the new technologies and their applications into other areas. Even though, most technological innovations hold the promise to transform the building industry and the architecture within, and although, there have been some limited attempts in this area recently; to date architecture has failed to utilize the vast amount of accumulated technological knowledge and innovations to significantly transform the industry. Consequently, the applications of new technologies to architecture remain remote and inadequate. One of the main reasons of this problem is economical. Architecture is still seen and operated as a sub-service to the Construction industry and it does not seem to be feasible to apply recent innovations in Building Technology area. Another reason lies at the heart of architectural education. Architectural education does not follow technological innovations (Watson 1997), and that “design and technology issues are trivialized by their segregation from one another” (Fernandez 2004). The final reason is practicality and this one is partially related to the previous reasons. The history of architecture is full of visions for revolutionizing building technology, ideas that failed to achieve commercial practicality. Although, there have been some adaptations in this area recently, the improvements in architecture reflect only incremental progress, not the significant discoveries needed to transform the industry. However, architectural innovations and movements have often been generated by the advances of building materials, such as the impact of steel in the last and reinforced concrete in this century. There have been some scattered attempts of the creation of new materials and systems but currently they are mainly used for limited remote applications and mostly for aesthetic purposes. We believe a new architectural material class is needed which will merge digital and material technologies, embedded in architectural spaces and play a significant role in the way we use and experience architecture. As a principle element of architecture, technology has allowed for the wall to become an increasingly dynamic component of the built environment. The traditional connotations and objectives related to the wall are being redefined: static becomes fluid, opaque becomes transparent, barrier becomes filter and boundary becomes borderless. Combining smart materials, intelligent systems, engineering, and art can create a component that does not just support and define but significantly enhances the architectural space. This paper presents an ongoing research project about the development of new class of architectural wall system by incorporating distributed sensors and macroelectronics directly into the building environment. This type of composite, which is a representative example of an even broader class of smart architectural material, has the potential to change the design and function of an architectural structure or living environment. As of today, this kind of composite does not exist. Once completed, this will be the first technology on its own. We believe this study will lay the fundamental groundwork for a new paradigm in surface engineering that may be of considerable significance in architecture, building and construction industry, and materials science.
