summary This paper presents an interface for interacting with tangible objects to produce and edit architectural 3D models, called TangiCAD. TangiCAD is a tangible/virtual construction kit which allows architects to manipulate virtual models using easy hand control of tangible cubes, as an alternative interface for 3D modeling. It consists of a set of tangible cubes representing architectural elements, such as walls, columns, slabs,…etc., in addition to some editing operations. With more developed versions, the paper argues that architects could use tangible interfaces to carry out 3D modeling in an intuitive way, using their "flip-the-box" hands-on movement.

summary Building projects today are not only born out digitally, but they are also realized digitally through "file-to-factory" processes of computer aided manufacturing (CAM) and computer numerically controlled (CNC) technologies. It was the challenge of constructability that brought into question, what new instruments of practice are needed to take advantage of the opportunities opened up by the digital modes of production, instead of whether a particular form is buildable. In this case of building construction, architects could design with attention to innovative details, afforded by unique shapes and sizes, knowing that whatever they created on their computer screen could be fabricated digitally for an affordable price. The aims of the research are to discuss and analyze the digital manufacturing techniques (CAM) in architecture and its fabrication, production process. To understand how these technologies fit within a broader context of architectural practice. The research begins with defining, what is digital manufacturing in architecture, its potentials, components and influences in the contemporary architecture. Further more it discusses the digital fabrication, Two- dimensional cutting, subtractive fabrication, additive fabrication and formative fabrication. The assembly technique, building skin, new materials and mass- customization in digital manufacturing techniques (CAM). That will be a hand in analyzing several case studies.

title Readiness for the Use of Technology for effective learning via the vds: Case of the United Arab Emirates

summary Review of the literature indicated that today’s knowledge-driven economy demands a workforce equipped with complex skills and attitudes such as problem solving, meta-cognitive skills, critical thinking and lifelong learning. Such skills can be acquired if learning and teaching are guided by the constructivist and cognitive learning theories. In particular, the constructivist approach emphasises effective learning processes based on learning by doing and collaboration. This approach is congruent with use of technologies, such as Virtual Design Studio (VDS), for the purpose of architecture education in design courses, but such use is lacking in the United Arab Emirates (UAE). It is thus important to assess the extent to which the constructivist and cognitive theories are implemented in teaching design courses in the Architecture schools of the UAE. It is also important to assess the effectiveness of employing technology in general and VDS in particular in implementing these theories. The author intends to study the relationship between effective learning on one hand and using VDS in implementing the constructivist and cognitive approaches on the other hand. Thus, the author conducted a preliminary study to gain a basic understanding of the difficulties, approaches, attitudes, perceptions, and motivation related to the learning of design in architecture schools in the UAE. Second, the investigation was designed to assess the extent to which the students would be interested in the use of sophisticated technology in the teaching and learning environment in the UAE architecture education schools in order to achieve effective learning. The study has been conducted in the United Arab Emirates University (UAEU). Methodology used for this was the focus group method. In addition to the focus group interviews with the UAEU students, unstructured individual interviews with lecturers from UAEU and the American University of Sharjah (AUS) have been carried out. Data analysis showed that students were not satisfied with the current teaching methods based on traditional lectures. It was concluded that students were ready to practice effective learning of design via the intermarriage of VDS and the constructivist and cognitive approaches. An ambiguity that remained was whether students were ready for assessment methods which are consistent with the constructivist approach.

title Detecting Inefficient Lighting Solutions: Step-by-Step Geographic information system (GIS) Technique

summary Outdoor lighting is used to illuminate roadways, parking lots, yards, sidewalks, public meeting areas, signs, work sites, and buildings. It provides us with better visibility and a sense of security. When well designed and properly installed, outdoor lighting can be and is very useful in improving visibility and safety and a sense of security, while at the same time minimizing energy use and operating costs. But, because nobody thought at this, most street lights shine light not only on the nearby ground, where is needed, but also miles away and skywards. Thus a large fraction of the light is lost, at consumer expense and without his/her consent. In the other hand, shortage in street light may cause more crimes as well as accidents. Most of the wasted or short light comes from the poorly designed street lights. Billboards, decorative lights, poorly shielded security lights are part of the problem too, but the main culprit for the waste and ugly glow one sees above one's head at nights is from the streetlights. Thus, recent computer technology gives us tools to be employed for testing the quality of light. Geographic Information System (GIS) software could be utilized to achieve that mission through applying mapping technique. This technique could analyze digital photographs and define light polluted areas as well as bad lighted. This paper reveals that step by step technique, which employs hybrid technologies to solve such problem for better planning decisions.

summary Real-time rendering is the most fundamental aspect of the virtual reality technology, which is always, a balance between hardware advancement and efficient software algorithm upgrades on the one hand and the demands of the quality output on the other. As architects who utilize this technology, what we can do as users is to optimize the parameters we can control in the files we input to run the simulation. Thus the identification of the few variables we can control to prevent a lagging performance or ghosting which is no longer realtime. The frame rate above all is the measurement to determine whether a simulation is real-time or not. The research aim is to identify the biggest contributing factors among the few identified. The intention is to save time and effort by optimizing the selected factors in projects so that we do not have to optimize all of them. The workflow will also be a lot faster and projects can be done efficiently. The final part is to run satisfaction tests among users to evaluate those biggest contributing factors and the qualities acceptable by users. This is to eliminate the added processing power needed to run bigger files if they do not contribute much to improved quality.

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

summary The educative proposal was based on the summary attained through experiences piled up during the 2 last semester courses, 2/2006-1/2007. This proposal corresponds to a mix of methodology (by personal attendance / by internet). Founding on the Theory of the Game (Eric Berne 1960) and on different theories such as: Multiple intelligences (Haward Gardner 1983), Emotional Intelligence (Peter Salowey and John Mayer 1990, Goleman 1998), Social Intelligence (Goleman 2006), the Triarchy of Intelligence (Stemberg, R.J. 1985, 1997), “the hand of the human power”, it´s established that the power of the voice, that of the imagination, the reward, the commitment and association produce a significant increase of the productivity (Rosabeth Moss Kanter 2000), aside from the constructive processes of the knowledge (new pedagogical concepts constructivista of Ormrod J.E. 2003 and Tim O´Reilly 2004).

summary Comparing space allocation programs computationally is a resource intensive task. This paper introduces a method which reduces the complexity of floor plan graphs to facilitate the problem. In a first step the nodes are labeled according to a laid out classification scheme. This in its own right reduces the complexity of the comparison by introducing more diversity among the nodes. Subsequently the graph can be coarsened in several steps based on the category information. This does not only further reduce the necessary computation, but can also offer a visualization of and additional insight into the essential structure of the space allocation program at hand.

summary Conceptual modeling is an actively creative stage in a design process. Through hand modeling and manipulation of different kinds of modeling tool kits for specific materials, designers are able to generate forms. This article presents a tangible human-computer interface of a C-StressBall for form manipulation and a C-BenchWhirler for visual control. They create a new way of interaction between the virtual world and the physical space. They are aimed to ease the operation in design process by using CAD.

title Integrative Design Strategies for Multimedia in Architecture
doi https://doi.org/10.52842/conf.acadia.2011.372
source ACADIA 11: Integration through Computation [Proceedings of the 31st Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA)] [ISBN 978-1-6136-4595-6] Banff (Alberta) 13-16 October, 2011, pp. 372-379
summary Multidisciplinary efforts that have shaped the current integration of multimedia into architectural spaces have primarily been conducted by collaborative efforts among art, engineering, interaction design, informatics and software programming. These collaborations have focused on the complexities of designing for applications of multimedia in specific real world contexts. Outside a small but growing number of researchers and practitioners, architects have been largely absent from these efforts. This has resulted in projects that deal primarily with developing technologies augmenting existing architectural environments. (Greenfield and Shepard 2007)This paper examines the potential of multimedia and architecture integration to create new possibilities for architectural space. Established practices of constructing architecture suggest creating space by conventional architectural means. On the other hand, multimedia influences and their effect on the tectonics, topos and typos (Frampton 2001) of an architectural space (‘multimedia effects matrix’) suggest new modes of shaping space. It is proposed that correlations exist between those two that could inform unified design strategies. Case study analyses were conducted examining five works of interactive spaces and multimedia installation artworks, selected from an initial larger study of 25 works. Each case study investigated the means of shaping space employed, according to both conventional architectural practices and the principles of multimedia influence (in reference to the ‘multimedia effects matrix’) (James and Nagasaka 2010, 278-285). Findings from the case studies suggest strong correlations between the two approaches to spatial construction. To indicate these correlations, this paper presents five speculative integrative design strategies derived from the case studies, intended to inform future architectural design practice.

title Visual-Physical Grammars
source SIGraDi 2008 - [Proceedings of the 12th Iberoamerican Congress of Digital Graphics] La Habana - Cuba 1-5 December 2008
summary This paper introduces new visual-physical design grammars for the design and manufacture of building assembly systems that provide visually rich, culturally resonant design variations for housing. The building systems are intended to be tailored for particular cultures and communities by incorporating vernacular, decorative design into the assembly design. Two complementary areas of computational design research are brought together in this work: shape grammars and digital fabrication. The visual or graphic aspects of the research are explored through shape grammars. The physical design and manufacturing aspects are explored through advanced digital design and fabrication technologies and, in particular, build on recent work on mono-material assemblies with interlocking components that can be fabricated with CNC machines and assembled easily by hand on-site (Sass, 2007). This paper describes the initial, proof-of-concept stage of this work: the development of an automated, visual-physical grammar for an assembly system based on a vernacular language of Greek meander designs. A shape grammar for the two-dimensional Greek meander language (Knight, 1986) was translated into a three-dimensional assembly system. The components of the system are uniquely designed, concrete “meander bricks” (Figure 1). The components have integrated alignment features so that they can be easily fitted and locked together manually without binding materials. Components interlock horizontally to form courses, and courses interlock vertically in different ways to produce a visual variety of meander walls. The assembly components were prototyped at desktop scale with a layered manufacturing machine to test their appearance after assembly and their potential for design variations (Figure 2). Components were then evaluated as full-scale concrete objects for satisfaction of physical constraints related to concrete forming and component strength. The automated grammar (computer program) for this system generates assembly design variations with complete CAD/CAM data for fabrication of components formed from layered, CNC cut molds. Using the grammar, a full-scale mockup of a corner wall section was constructed to assess the structural, material, and aesthetic feasibility of the system, as well as ease of assembly. The results of this study demonstrate clearly the potentials for embedding visual properties in structural systems. They provide the foundations for further work on assembly systems for complete houses and other small-scale structures, and grammars to generate them. In the long-term, this research will lead to new solutions for economical, easily manufactured housing which is especially critical in developing countries and for post-disaster environments. These new housing solutions will not only provide shelter but will also support important cultural values through the integration of familiar visual design features. The use of inexpensive, portable digital design and fabrication technologies will allow local communities to be active, cooperative participants in the design and construction of their homes. Beyond the specific context of housing, visual-physical grammars have the potential to positively impact design and manufacture of designed artifacts at many scales, and in many domains, particularly for artifacts where visual aesthetics need to be considered jointly with physical or material requirements and design customization or variation is important.

summary The paper is focused on selected issues of preliminary education of computer techniques as part of first semester curriculum at a school of architecture. Teaching methods based on previously known research are tested and explored in a situation of clearly defined constraints: lack of architecture-specific knowledge of the novices and varying levels of their computer skills. The paper is based on three-year experience. Although we are all in the mood of saying: we do not teach software any more, we still have to think how to encourage students to develop their skills in computer techniques to the level that can liberate them from tool-dependence. The aim is to direct them towards task rather than tool oriented actions. Learning while designing causes the design process to be less important than representation. On the other hand, classic software courses are a thing of the far past and are not suited for design-oriented curriculum. There is a need to find alternative ways more suitable for a preliminary architecture IT course.

title BIM as a Viable Collaborative Working Tool: A Case Study

summary For the majority of design practices in the construction industry the use of CAD systems have been used to merely automate hand drafting (Cohen 2003). This is the traditional way of working that has changed very little since the introduction of commercial CAD systems. These practices as means of communication are being replaced by a virtual building model environment which encapsulates all of the information for an entire construction project and thereby enables computer-supported co-operative working practices. (Newton 2003) This study aims to determine whether Building Information Modelling (BIM) can, and whether it will, replace traditional communication media as the standard in the industry for computersupported co-operative working practices in the Architecture Engineering and construction (AEC) sector. The bulk of the research comprises an extensive literature review looking at the principal reasons behind the development of BIM, the potential advantages and drawbacks of the technology, and the barriers and obstacles which inhibit its adoption as a means of computer-supported co-operative working. The findings of the study have been validated and analysed against current practice in the field through a live case study analysis of the on-going Heathrow airport Terminal 5 Project in London (UK). The Terminal 5 case study demonstrates that present software tools, although usable, still present significant implicit technical constraints to wider implementation among Small and Medium Enterprises (SMEs). The case study has also shown that in practice, the success of BIM depends just as much on the working practices and ethos of participants in the project chain as it does on the capabilities of the software itself, in particular the willingness of practitioners to change traditional working practices. The case study has shown that the present investment, in terms of time, cost, and effort required to implementing the technology means that BIM is unlikely to be adopted on small simple projects where conventional CAD is still adequate. It also highlighted that BIM tools currently available are not yet adequately developed to satisfy the requirements of the many procurement and especially contractual arrangements which presently exist and many firms will be frightened off by the unresolved legal issues which may arise from implementing BIM in their practices.

In this paper we introduce novel approaches that contribute to the generation and visualization of dynamic complex urban systems. We distinguish reality-based and generic city models. On the one hand we look a three dimensional models of urban environments. On the other hand we are looking at the key challenges and trends that will shape future cities. We are drawing parallels to functional models of brain circuitry. City modeling as a case in point provides the basis for our research to arrive at a transdiciplinary theory of design and modeling.

title Applying generative modeling procedure to explore architectural forms

summary Computer generated 3D forms using generative procedures have matured in the last decade and now considered as a tangible approach for realizing architectural design ideas. As fascinating as the approach might be, it is still lacking actual application in the early architectural design process. There are many reasons for this, among them: it has many implications over the architectural design process mainly the practicality of design during the conceptual design stage; it is cumbersome to develop construction drawings for complex architectural forms; and the necessity for producing conceptual designs quickly in less time as design requirements and decisions are constantly being changed. This paper initially reports on a practical development of a computer program which generates architectural massing designs based on integrating forms generation technique in a design scheme. The influence for this development was inspired by Spirolaterals technique used in generating complex 3D architectural forms that are based on parametric shape configuration. The development has three goals: to review the principles for constructing generative forms in the conceptual design stage using simple CAD tools, to assist in the production of design schemes based on a few basic shapes and rules, and to explore 3D forms finding and generation without the need to write a complicated computer program that are difficult to produce by hand. The development resulted in generating an interesting number of 3D compositions. The author applied this technique to experiment during the production of a design scheme. The paper hence describes the current development of ArchiGen tool to produces generative 3D forms utilizing ArchiCAD © GDL programming language. The tool is embedded within ArchiCAD for generating 3D shapes. One of the main features of this implementation is that users are able to sketch 2D shapes and the tool will deform its three dimensional generation. Moreover, the user being able to abstract the architectural character from the resulting complex 3D shapes. This development extends current related work by allowing the designer to load shapes into ArchiGen which acts as vocabulary of shapes for a design scheme constraints. It is intended from this work to inspire future work focusing on using generative tools in the early conceptual design stages.

title Simulating Dynamic Forces in Design with Special Effects Tools
doi https://doi.org/10.52842/conf.ecaade.2007.219

summary Special effects technology can facilitate dynamic sketching in the early stage of a design project without needing time-consuming effort. This form of sketching was tested in a design studio taught by the author. The study of dynamic materials and oceanfront site conditions set the stage at the beginning of a design process for a more comprehensive analysis later on. On the one hand, the risk of using special effects tools is that the visual look can seem convincing, but the apparent result is based upon an overly simplified set of assumptions. On the other hand, the use of such technology can be very stimulating to the design imagination without requiring complex analysis that may bog down the free flow of ideas. Once a greater commitment is made to a particular design proposal, more complete physical analysis and modeling can be undertaken to help avoid the risk of false first impressions. In the studio, cloth simulation was used to develop the design of tension membrane structures (tents) that retracted and unfurled in a series of complex movements. Fluid dynamics effects were used in the design and development of related boat dock facilities. A wind-tunnel simulation tool was used to explore the performance of the tension-membrane fabrics under varied wind loads. The visualization techniques were complemented by ¼ to ½ scale assembled components created by rapid prototyping. The use of an actual wind-tunnel further tested the prototypes in some cases. On the whole, quickly implemented special effects were the starting point for reacting to and developing some initial design concepts and served as the basis for more complete physical modeling of prototypes later on. Using animation as a design method is well established in other work (Hirschberg 06). Animation is also a helpful way to work out the step by step assembly of complex architectural form (Mark 95). The special effects tools permit a larger range of initial design alternatives to be initially considered that are subsequently narrowed down by physically based prototypes that are more predictive of real world performance.

title Simulating the Use of Ancient Technology Works Using Advanced Virtual Reality Technologies
source International Journal of Architectural Computing vol. 5 - no. 2, pp. 256-282
summary This paper introduces a novel framework for the modeling and interactive simulation of ancient Greek technology works with the use of advanced virtual reality technologies. A novel algorithm is introduced for the realistic and efficient resolution of collisions that is based on an advanced collision detection approach that can also calculate in real-time the force that should be fed back to the user using a haptic device. Thus, the user is capable of manipulating the scene objects in the environment using haptic devices to simulate the sense of touch and stereoscopic imaging so as to be immersed in the virtual environment. Moreover, the virtual hand that simulates the user's hand is modeled using superquadrics so as to further increase the speed of the simulation and the fidelity of the force feedback. Extended evaluation of the system has been performed with visitors of the Science Center and Technology Museum of Thessaloniki.

title A Theoretical Framework for the Implementation of Building User’s Lifestyle in nD CAD System
source Em‘body’ing Virtual Architecture: The Third International Conference of the Arab Society for Computer Aided Architectural Design (ASCAAD 2007), 28-30 November 2007, Alexandria, Egypt, pp. 595-606
summary People’s lifestyle, traditions and culture affect the way they live, interact with the built environment and erect buildings. Lifestyle influences the physical characteristics of the space such as: organization of spaces, distances between spaces and location of spaces. Taking lifestyle aspects into account by architects would provide comfortable environment that is tailored to people needs and aspirations. On the other hand, rapid developments in computer modeling of buildings since 1960, led to the invention of 3D CAD systems that are capable of modeling the physical volume, shape and form of buildings and helping project team members to virtually visualize buildings. 4D CAD systems went beyond the mere 3D modeling of the physical building as they link the 3D virtual building model with other building’s information such as construction process, cost estimation etc. The nD CAD research that emerged in the late 1990s proposed endless dimensions of CAD modeling that would include the building regulations’ requirements, basic user needs and client requirements. This paper argues that it would not be enough to model the client requirements and some of user/ occupant’s physical and environmental aspects as it does not reflect the real utilization of the building by building’s user and the way that he/ she likes to live. This research aims to define the lifestyle characteristics of the architectural space and its boundaries. It suggests that various aspects of the user’s lifestyle such as degree of privacy, flexibility and adaptability required for each space, organization of internal spaces and style of spaces should be implemented in the future nD CAD models. Such implementation would enable designers to consider real life scenarios, model the real needs of people and provide the adequate end product for them.

title The Role of Cases in Architectural Practice and Education Moneo: An Architectural Assistant System
source Em‘body’ing Virtual Architecture: The Third International Conference of the Arab Society for Computer Aided Architectural Design (ASCAAD 2007), 28-30 November 2007, Alexandria, Egypt, pp. 215-228
summary The work presented here describes a prototype application, called MONEO that makes use of case based reasoning (CBR) in the field of architectural design. MONEO is a tool that aids architectural students as well as practicing architects in the pre-design phase by supplying them with an adequate number of similar past architectural cases to the design problem they have at hand. The different modules of MONEO will be presented and discussed, as well as the tools used to develop them.
