title	Open-source, parametric architecture to propagate hyper-dense, sustainable urban communities: parametric urban dwellings for the experience economy
doi	https://doi.org/10.52842/conf.caadria.2010.443
source	Proceedings of the 15th International Conference on Computer Aided Architectural Design Research in Asia / Hong Kong 7-10 April 2010, pp. 443-452
summary	Rapid developments in societal, technological, and natural systems suggest profound changes ahead if research in panarchical systems (Holling, 2001) is to be believed. Panarchy suggests that systems, both natural and man-made, rise to the point of vulnerability then fail due to disruptive forces in a process of ‘creative destruction.’ This sequence allows for radical, and often unpredictable, renewal. Pressing sustainability concerns, burgeoning urban growth, and emergent ‘green manufacturing’ laws, suggest that future urban dwellings are headed toward Gladwell’s ‘tipping point’ (2002). Hyper-dense, sustainable, urban communities that employ open-source standards, parametric software, and web-based configurators are the new frontier for venerable visions. Open-source standards will permit the design, manufacture, and sale of highly diverse, inter-operable components to create compact urban living environments that are technologically sophisticated, sustainable, and mobile. These mass-customised dwellings, akin to branded consumer goods, will address previous shortcomings for prefabricated, mobile dwellings by stimulating consumer desire in ways that extend the arguments of both Joseph Pine (1992) and Anna Klingman (2007). Arguments presented by authors Makimoto and Manners (1997) – which assert that the adoption of digital and mobile technologies will create large-scale societal shifts – will be extended with several solutions proposed.

title	Intervision3D: Online 3D Visualisation and Conferencing
doi	https://doi.org/10.52842/conf.caadria.2007.x.l3p

summary	The use of Internet communication technologies in distributed teams has been carried out for well over 10 years. In this time, various methods to communicate and transfer information have been developed. A large amount of effort has been placed on enabling normal conversation to take place and it could be said, that with technologies like Skype, this is established. This enables planning partners to discuss, but we still need to convey what they are discussing. In short, the contents are still lacking. Technologies exist to allow users to share files or images, however this does not nearly reach the intensity or quality of discussions when partners are sitting together in front of a drawing or model. At best, screen sharing allows participants to see the same image but with low resolution and bad system response. The goal of the Intervision3D project is to allow distributed team members to discuss design issues with a common 3D model where participants can manipulate the model together in real time. In contrast to screen-sharing solutions, the Intervision3D project uses a server, which delivers a copy of the model to each conference participant. The server then coordinates the perspective views of all conference participants. One of the participants (usually the first) is initially designated as the speaker and he or she controls the views of the model through an intuitive walk/fly-through interface. The speed of the system is also buttressed by the simplicity of the application: as a Java applet, it is possible to start the Intervision3D system in any browser or as a separate applet on any system. As such, none of the participants need to install anything. The resolution of the model is optimized for each participant's browser and computer display. Currently, Intervision3D can import .3ds files and then render them using the JOGL Engine (Java Bindings for Open GL). JOGL allows the full Open GL suite to be used in rendering the model including lighting and textures: even normal PCs can do this quite well. The first implementation of the system is within an existing internet-based Design Studio and the paper elucidates how the first uses of the system have (partially) helped to increase the exchange of design ideas over the Internet. Through the Intervison3D system, the participants who have been separated by distance can once again discuss the same 3D model.

title	Punching Above Your Weight: Digital Design Methods and Organisational Change in Small Practice
doi	https://doi.org/10.52842/conf.acadia.2007.040
source	Expanding Bodies: Art • Cities• Environment [Proceedings of the 27th Annual Conference of the Association for Computer Aided Design in Architecture / ISBN 978-0-9780978-6-8] Halifax (Nova Scotia) 1-7 October 2007, 40-47
summary	Expanding bodies of knowledge imply expanding teams to manage this knowledge. Paradoxically, it can be shown that in situations of complexity—which increasingly characterise the production of architecture generally—the small practice or small team could be at an advantage. This is due to the increasingly digital nature of the work undertaken and artefacts produced by practices, enabling production processes to be augmented with digital toolsets and for tight project delivery networks to be forged with other collaborators and consultants (Frazer 2006). Furthermore, as Christensen argues, being small may also be desirable, as innovations are less likely to be developed by large, established companies (Christensen 1997). By working smarter, and managing the complexity of design and construction, not only can the small practice “punch above its weight” and compete with larger practices, this research suggests it is a more appropriate model for practice in the digital age. This paper demonstrates this through the implementation of emerging technologies and strategies including generative and parametric design, digital fabrication, and digital construction. These strategies have been employed on a number of built and un-built case-study projects in a unique collaboration between RMIT University’s SIAL lab and the award-winning design practice BKK Architects.

title	Digital Resource Semantic Management of Islamic Buildings Case Study on Isfahan Islamic Architecture Digital Collection
source	International Journal of Architectural Computing vol. 5 - no. 2, pp. 356-373
summary	This article describes an innovative way to facilitate and to provide a collaborative semantic management of digital resources of Islamic historical buildings. The approach combines a topic maps-based semantic support to the 5W1H model (Where, Who, When, What, Who and How) with objective of enabling comprehensive semantics of digital contents for research and education purposes. The topic maps-based semantic support enables to reduce the problems of semantic gaps among different communities (cultural, linguistic ambiguities among various types of multi-disciplinary experts). Furthermore, a multi-faceted resource category management, applied to metadata sets and related semantic features, allows metadata optimization of the description of the cultural resources. This innovative approach has been used to build the Isfahan Islamic Architecture Database (IIAD) Collection as a case study. The research demonstrates that a topic maps-based semantic model applied to collaborative metadata management paradigms can be easily exploited as a tool to enhance traditional architectural and cross-disciplinary studies.

title	Mobile Augmented Heritage: Enabling Human Life in Ancient Pompeii
source	International Journal of Architectural Computing vol. 5 - no. 2, pp. 396-415
summary	We propose a new methodology for real-time mobile mixed reality systems that feature realistic simulations of animated virtual human actors (clothes, body, skin, face) who augment real environments and re-enact staged storytelling dramas. Although initially targeted at Cultural Heritage Sites, the paradigm is by no means limited to such subjects. The abandonment of traditional concepts of static cultural artifacts or rigid geometrical and 2D textual augmentations with 3D, interactive, augmented historical character-based event representations in a mobile and wearable setup, is the main contribution of the described work as well as the proposed extensions to AR Enabling technologies: a VR/AR character simulation kernel framework with character to object interaction, a markerless camera tracker specialized for non-invasive geometrical registration on heritage sites and a PRT mixed reality illumination model for more consistent real-virtual real-time rendering. We demonstrate a real-time case study on the actual site of ancient Pompeii.

source	SIGraDi 2007 - [Proceedings of the 11th Iberoamerican Congress of Digital Graphics] México D.F. - México 23-25 October 2007, pp. 205-209
summary	This research seeks the development of mobile learning applications that provide ubiquitous training in visual-spatial skills using wireless handheld mobile devices (i.e. PDA, cell phones). The paper reports about the findings of a first stage in which the application targeted the handling of spatial representations and the qualitative understanding of 3D spaces. Evidence was collected regarding effectiveness of the instructional strategy related to specific aspects of the students’ visual-spatial competency and obtained qualitative feedback regarding the students’ level of satisfaction about the learning experience using the initial prototype. The paper provides recommendations for future implementations of an m-learning beta version.

title	Ubiquitous Training of Visual-Spatial Skills: On the Development of Mobile Applications Using Handheld Devices
doi	https://doi.org/10.52842/conf.acadia.2007.146
source	Expanding Bodies: Art • Cities• Environment [Proceedings of the 27th Annual Conference of the Association for Computer Aided Design in Architecture / ISBN 978-0-9780978-6-8] Halifax (Nova Scotia) 1-7 October 2007, 146-155
summary	This research project seeks to develop m-learning applications that provide training in visual-spatial skills using wireless handheld mobile devices (e.g. PDAs and cellular phones). The paper acknowledges the role of visual-spatial competence as fundamental in science and most creative endeavors, including its critical role in architectural design. It also recognizes that there is a substantial amount of anecdotal evidence suggesting that undergraduate students in architecture have serious limitations in applying visual-spatial skills for design activities. A potential solution to this problem is envisioned through the introduction of extra-curricular learning activities that are ubiquitous and learner-centered. The suggested m-learning applications will include a set of instructional modules making use of media-rich representations (graphics and animations) for conveying the nature of 3-D spaces. As a first step toward reaching this development, a prototype was created and used for testing learning strategies. This experiment provided evidence regarding improvements to specific aspects of the students’ visual-spatial competency, and it also collected qualitative feedback regarding the students’ level of satisfaction about the learning experience. The paper provides recommendations for a future implementation of the beta version, including the learning strategy, content authoring, publishing, deployment, and criteria for the selection of the most accessible mobile device.

summary	The paper presents an ongoing project to interactively simulate urban and regional dynamics at the building scale. Urban Generator is a system for generating a large number of design solutions and for browsing, searching and structuring the high-dimensional space of the design solutions further to variable and customisable factors defined by the designer. The number of these factors is recognised as large; furthermore they are often ill-defined. Urban Generator does not model every factor; instead it supports the designer in defining the significant factors and their interconnections, then freely exploring the dimensions of the space of the design solutions generated by the system.

summary	The objective of the paper is to demonstrate the application of architectural research and design methods from the fields of strategic design, digital production and design chains to facilitate the completion of demanding large-scale building projects. Since we have concentrated the efforts of the past few years on various aspects of building practice while applying and testing the “Digital Chain” method to several concrete projects, we are now engaged with linking the individual phases in order to make the final step towards the reality of building practice. With this knowledge, we attempt to propose a new way of thinking in the design and building sector based on digitized planning processes.

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 Ocean Tracking Network (OTN) is a large-scale global initiative that comprehensively monitors ocean conditions and marine life response to these conditions. Scientists are tagging sea creatures, from salmon to whales, with tiny transmitters so that their movements can be tracked for over 20 years by receivers placed at one-kilometre intervals along the ocean floor. Pressure sensors added to these receivers allow real-time measurements of ocean depth, temperature and salinity, all of which provide significant information about climate change and the likelihood of natural disasters such as tsunamis. On shore, scientists around the world can receive this information regularly and upload it to a central database, resulting in current and reliable international records.

summary	This paper presents an approach to creating an online real time rendering environment, upon which a large-scale, urban 3D model can be produced as a collaborative effort between initial content creators and outside parties with an interest in simulation and visualization. In 2007, the City of Atlanta, Georgia organized a taskforce to provide recommendations on the future development and mobility along the city’s signature street, Peachtree Street. To aid in the visualization of this area, datasets were converted into low polygon textured 3D models for the entire study area. This content will serve as the foundation of a collaborative effort to complete a high quality real time environment. The process for this project will be described and the means to extend the boundaries, maintain, and collaborate with this content will be proposed.

title	The Urban Simulation and Projects Evaluation Laboratory at the Politecnico di Milano: An Educational and Research Facility
source	Projecting Spaces [Proceedings of the 9th European Architectural Endoscopy Association Conference / ISBN 978-3-942411-31-8 ], pp. 115-120
summary	At the beginning of 2007 an Italian Urban Simulation Laboratory was founded at the Politecnico di Milano. The laboratory, coordinated by prof. Fausto Curti, has been developed thanks to the one year presence of the visiting professor Peter Bosselmann, director of the Environmental Simulation Laboratory at the University of California at Berkeley. The laboratory has an interdisciplinary approach and a threefold mission: experiment, using the laboratory setting to study urban projects at different scales; communicate, aiding public communication by making urban projects understandable to everyone; integrate and innovate, working on different kind of simulations techniques in an integrated way. In its initial experience the laboratory is primarily a didactic and research facility. Students can join the work and participate actively to the research. Until now about 40 students have worked with us, more than a half were foreign students from all over the world. The majority of the students did an internship of about 150 (three-year degree) or 300 (master degree) hours and some of them have continued working after this period developing a thesis. At the moment the case study, used as a pilot research, is about the Porta Nuova project at the Garibaldi- Repubblica area in Milan. The 300.000 mq of the total area and its well served central position make this place strategic for Milan. In this area the adopted urban transformation plan is creating a new business center that affects redevelopment projects, new infrastructures, and a park. The overall project will overhanging the surroundings city center with some of the highest buildings of its skyline. The importance of the site and the dimension of the project make this case significant to test the use of simulation for supporting evaluations about morphological aspects, comfort conditions, visual impacts, and other aspects that directly influence the quality of the new urban spaces. We are now applying different simulation methodologies in order to better understand the peculiar usefulness of each kind as a tool to support evaluation. As any kind has its own limits we work with different typologies at the same time. We are working with 1:500 scale physical model of a 1 km square of the area and different kind of static and dynamic simulations. We developed, with an external office, a micro-car to move a micro-camera in the maquette. We use this equipment to better explain the project implications to the students by producing subjective shot videos or showing a walk in real-time. To reproduce in a better way some relevant walks through the transformed site we have also produced some videos made of a superimposition of the real existing context and the virtual projects. To do this we used a rendered video of the project superimposed to the filmed promenade of the today condition, previously recorded using steadycam. A lot of static simulations has been employed to better understand the new city configuration from some representative points of view, as for example the roof of the Duomo cathedral. We are now developing some other kinds of analysis such as shadows impact; this is done by using a 1:1000 scale maquette in the Heliodon, but also with some digital tools. In the next future a work with the wind tunnel will help to understand some other comfort implications of the project at the micro-urban scale. The multilayer approach is the main aim of the laboratory and is an important tool to clarify the multidimensional project impacts to the students. In this way the laboratory can be a learning tool, it can stimulate the project process and support decision-making while improving the knowledge about the correct use of simulations for evaluating the cumulative implications of the proposed urban processes.

title	Foam Structures: A Comparative Structural Efficiency Analysis Based on the Building Case "Watercube"
source	Vienna University of Technology; Building Science & Technology
summary	Foam structure in macro-scale has arisen as a new type of large span building structure recently which is a product of cooperation of advanced structural design, radical architectural design approach, and computer and software technology, and efficiency of foam structure became an important question to answer which could help further structural improvements. This study analyses efficiency of large span foam structure relative to conventional large span building structures with a parametric simulation method. Space frames are a special case of conventional large span structures one compared with foam structures, because it satisfies criteria such as being lightweight and three-dimensional as foam structure. Analysis is based on the comparison of base cases of foam model and space frame model, which are developed on light of real projects the Water Cube and the Symbol Zone of Expo’70, based on the parameters structural depth, weight and displacement, and vertical and horizontal load cases. During the analysis structural behavior of base cases were simulated by using a special structural behavior simulation program. It was found that foam model is more efficient than space frame model in terms of structural depth which is an important issue for large span building structures from both architectural and engineering point of view. Capability of spanning large distance with significantly less structural depth makes foam structure a preferable, new generation, steel structure for large spans. Moreover, the development process of base case foam model demonstrated the critical importance of geometrical design concerns of foam structure. Structural behavior simulations were exposed that structural optimization is one of the vitally important process of structural design of the foam structure.

summary	At present more than half of all building activity in the German building sector is undertaken within existing built contexts. Work in existing building fabric is an essential aspect of most architects’ activities. The development of a conceptual and technological basis for the digital support of design directly on site, in and with the available architecture is the main focus of the research project “Spatial Augmented Reality for Architecture”. This article describes one part of the research project: the sampling of colours and materials at a scale of 1:1 using Augmented Reality technologies. This makes it possible to project the colour and material qualities of a design directly onto any surface within an existing building, geometrically corrected. A first software prototype SAR-CA has been developed and then assessed using a user study to obtain a first evaluation of the prototype to determine the direction of future research. Future research areas are discussed at the end of the paper.

summary	Building Information Modelling (BIM) is an emerging technology in the architecture/engineering/construction industry. This paper presents a case study of the implementation of BIM at the precontract stage of a small scale in-door swimming pool project in Hong Kong. It aims at reviewing the workflow between consultants and the impacts on design visualisation, drawing documentation and bills of quantities. A practicable approach to transform designers’ traditional 2D drawings to BIM with the support from a BIM manager is unveiled. In addition to the results, this paper also highlights some issues such as hardware requirements, the shortfalls of the BIM tool and the supply and demand of skilled BIM personnel. There are other unanswered questions to be addressed in the near future.

summary	In the last twenty years, computer tools have progressively enabled the modeling of buildings and cities in lesser time and cost, along with an increase in the results quality. A city modeled according to planning regulations usually present a correlation between plots and buildings dimensions. The representation of such correlation for a large number of plots requires repetitive work, thus suggesting the use of a computational tool to perform the task. Existing CAD, GIS, and VR software can generate accurate representations of the reality, but have no capabilities to simulate the impact of alternative urban regulations for large number of plots in a short period of time. CityZoom is a Decision Support System for urban planning, with a specific built-in city model, where data is represented in an object-oriented model representing the urban structure. CityZoom not only provide CAD tools, but a shell where different performance models can operate iteratively. It can simulate given urban regulations applied to a set of urban plots, as well as address environmental comfort issues such as shadow casting between buildings. Results can be displayed as tables, graphs, and in a 3D preview of the whole city or part of it. It’s also possible to export them to commercial GIS tools, to perform different data analysis. The graphical outputs make for an easy understanding of the results by laymen, an important feature for participatory planning, while the display of the correspondent numerical data enable correlations with indicators and parameters of urban quality.

title	Understanding Pre-Construction Simulation Activities to Adapt Visualization in 4D CAD Collaborative Tools

summary	Increasing productivity and efficiency is an important issue in the AEC field. This area is mainly characterized by fragmentation, heterogeneous teams with low lifetimes and many uncertainties. 4D CAD is one of the greatest innovations in recent years. It consists in linking a 3D model of the building with the works planning in order to simulate the construction evolution over time. 4D CAD can fill several needs from design to project management through constructivity analysis and tasks planning (Tommelein 2003). The literature shows that several applications have been proposed to improve the 4D CAD use (Chau et al. 2004; Lu et al. 2007; Seok & al. 2009). In addition, studies have shown the real impact of 4D CAD use in construction projects (Staub-French & Khanzode 2007; Dawood & Sika 2007). More recently, Mahalingam et al. (2010) showed that the collaborative use of 4D CAD is particularly useful during the pre-construction phase for comparing the constructability of working methods, for visually identifying conflicts and clashes (overlaps), and as visual tool for practitioners to discuss and to plan project progress. So the advantage of the 4D CAD collaborative use is demonstrated. Moreover, several studies have been conducted both in the scientific community and in the industrial world to improve it (Zhou et al. 2009; Kang et al. 2007). But an important need that remains in collaborative 4D CAD use in construction projects is about the adaptation of visualization to the users business needs. Indeed, construction projects have very specific characteristics (fragmentation, variable team, different roles from one project to another). Moreover, in the AEC field several visualization techniques can represent the same concept and actors choose one or another of these techniques according to their specific needs related to the task they have to perform. For example, the tasks planning may be represented by a Gantt chart or by a PERT network and the building elements can be depicted with a 3D model or a 2D plan. The classical view (3D + Gantt) proposed to all practitioners in the available 4D tools seems therefore not suiting the needs of all. So, our research is based on the hypothesis that adapting the visualization to individual business needs could significantly improve the collaboration. This work relies on previous ones and aim to develop a method 1) to choose the best suited views for performed tasks and 2) to compose adapted multiple views for each actor, that we call ‚Äúbusiness views‚Äù. We propose a 4 steps-method to compose business views. The first step identifies the users‚Äô business needs, defining the individual practices performed by each actor, identifying his business tasks and his information needs. The second step identifies the visualization needs related to the identified business needs. For this purpose, the user‚Äôs interactions and visualization tasks are described. This enables choosing the most appropriate visualization techniques for each need (step 3). At this step, it is important to describe the visualization techniques and to be able to compare them. Therefore, we proposed a business view metamodel. The final step (step 4) selects the adapted views, defines the coordination mechanisms and the interaction principles in order to compose coordinated visualizations. A final step consists in a validation work to ensure that the composed views really match to the described business needs. This paper presents the latest version of the method and especially presents our latest works about its first and second steps. These include making more generic the business tasks description in order to be applicable within most of construction projects and enabling to make correspondence with visualization tasks.
