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	Second City
doi	https://doi.org/10.52842/conf.ecaade.2007.359
source	Predicting the Future [25th eCAADe Conference Proceedings / ISBN 978-0-9541183-6-5] Frankfurt am Main (Germany) 26-29 September 2007, pp. 359-365
summary	In the era of communication, the participation in internet-communities has grown to become a motor for innovation in software and community platforms. The paper describes the hypothesis that, by creating a virtual city (or a second city) a new type of social, economic and scientific network is established, which is supported through visual communication technologies. The various users bring, per se, their own intrinsic motivation and requirements to the system. Nonetheless, a personal identification with a city/neighbourhood/house/apartment can be used to awake awareness and to foster participation. This is especially important when dealing with the city inhabitants. City modelling itself has been carried out for over a decade. Projects such as the city model of Graz have shown how city models can be established so as to be scalable for new information (Dokonal et al 2000). Furthermore, these city models have been used in the education of future architects and urban planners. The project described here moves in the opposite direction: the model moves out of the classroom to an interdisciplinary city-model-platform. The work described here is the conceptual model for a multi-dimensional data set that models the city. This has spawned a host of other projects using the model as a foundation for further interactivity development and the extension of the model itself. The paper describes the structure of the conceptual model and the first experience of incorporating diverse projects such those mentioned above. The model also is structured so as to be compatible with the XML standards being developed for city information (CityGML). The goal of the project is to create a data set describing the city that not only describes the geometry, but also the history (including planned histories) and nature of the city. In contrast to virtual realities, which attempt to create a separate world (e.g. Second Life), the Second City is intended as an interdisciplinary repository for the geometrical, historical and cultural information of the city.

title	Map-Based Repository of Image System for Sharing the Photographs in Design Studio
doi	https://doi.org/10.52842/conf.ecaade.2007.151
source	Predicting the Future [25th eCAADe Conference Proceedings / ISBN 978-0-9541183-6-5] Frankfurt am Main (Germany) 26-29 September 2007, pp. 151-157
summary	In the preparation of urban designs, it is important for the designer to understand the space feature of the project district and to obtain the design resource from the site. In our design studio, students take pictures of a point of interest (POI) in the project district and discuss the design concept of the district based on the photographs. To share the photographs obtained by the students during the field survey along with the attribute information and shooting positions, the present authors have developed a Web-based image archive system as an effective resource for a design studio. This system registers the photographs taken in the surveying district on GoogleMap and simultaneously displays the images on a three-dimensional city model. In this paper, we discuss the development of a Map-based Repository of Image (MRI) system to share the photographs of a city. Moreover, we attempt to evaluate its pedagogical effect in the design studio.

title	An overview of virtual city modelling: emerging organisational issues
source	CUPUM07 10th International Conference on Computers in Urban Planning and Urban Management, Iguassu Falls, Brazil, 11-13 July 2007
summary	This paper presents a recent overview of the increasing use of Virtual Reality (VR) technologies for the simulation of urban environments. It builds on previous research conducted on the identification of three-dimensional (3D) city models and offers an analysis of the development, utilization and construction of VR city models. Issues pertaining to advantages, barriers and ownership are identified. The paper describes a case study of the development of a VR model for the city of Newcastle upon Tyne in the UK and outlines the role that academic institutions can play in both the creation and utilization of urban models. The study offers a new approach for the creation, management and update of urban models and reflects on issues which are emerging. Areas for future research are discussed.

title	Self-shaping Textiles - A material platform for digitally designed, material-informed surface elements
doi	https://doi.org/10.52842/conf.ecaade.2020.2.021
source	Werner, L and Koering, D (eds.), Anthropologic: Architecture and Fabrication in the cognitive age - Proceedings of the 38th eCAADe Conference - Volume 2, TU Berlin, Berlin, Germany, 16-18 September 2020, pp. 21-30
summary	Despite the cutting edge developments in science and technology, architecture to a large extent still tends to favor form over matter by forcing materials into predefined, often superficial geometries, with functional aspects relegated to materials or energy demanding mechanized systems. Biomaterials research has instead shown a variety of physical architectures in which form and matter are intimately related (Fratzl, Weinkamer, 2007). We take inspiration from the morphogenetic processes taking place in plants' leaves (Sharon et al., 2007), where intricate three-dimensional surfaces originate from in-plane growth distributions, and propose the use of 3D printing on pre-stretched textiles (Tibbits, 2017) as an alternative, material-based, form-finding technique. We 3D print open fiber bundles, analyze the resulting wrinkling phenomenon and use it as a design strategy for creating three-dimensional textile surfaces. As additive manufacturing becomes more and more affordable, materials more intelligent and robust, the proposed form-finding technique has a lot of potential for designing efficient textile structures with optimized structural performance and minimal usage of material.

title	Novel Approaches to City Modeling: Generation and Visualization of Dynamic Complex Urban Systems
doi	https://doi.org/10.52842/conf.ecaade.2007.343

summary	This year, for the first time in history more people are living in cities than in the country. This fact induced us to look at the topic of city modeling from different sides. 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	Heuristic Methods in Architectural Design Optimization
doi	https://doi.org/10.52842/conf.ecaade.2007.507
source	Predicting the Future [25th eCAADe Conference Proceedings / ISBN 978-0-9541183-6-5] Frankfurt am Main (Germany) 26-29 September 2007, pp. 507-514
summary	This paper focuses on optimization methods and their role in the “digital chain” in architectural design and production. These methods were developed in the research phase of the project ‘New Monte Rosa Shelter’ to improve cost efficiency and to adapt the design for the specific environmental and constructive constraints of the site. The New Monte Rosa Shelter is a project designed by students for a mountain shelter at high altitude. For transportation and construction reasons, optimization was required to minimize costs, material, and weight of the structure. For this project a series of programs using genetic algorithms were written to optimize the geometry of the wooden framework. These programs were combined to create a digital toolset, giving the architects direct output of surface information from the framing data, and allowing for output as a three-dimensional model. This optimization toolset gives creative control back to the architects themselves, who can now transform and manipulate the architecture. This paper describes the overall process, and outlines one specific optimization tool, a program that enables architects to “fill” the wooden framework automatically with different material and construction systems and understand the cost and efficiency implications based upon the structural analysis software and the programmed heuristic methods.

title	Three dimensional isovist analysis method [Método de Análisis Tridimensional con isovistas]
source	SIGraDi 2007 - [Proceedings of the 11th Iberoamerican Congress of Digital Graphics] México D.F. - México 23-25 October 2007, pp. 174-176
summary	This paper presents a three dimensional method of isovist analysis implemented in the MaxScript programming language. The script accepts as its input a standard three dimensional model of the buildings and terrain being analyzed, upon which a N×N grid is projected. Each square of this grid is assigned a height value, thereby producing a simplified surface description which is amenable to mathematical analysis. A three dimensional isovist is then generated for each grid square, by placing an observation point 1.5 meters above its center and finding the intersection of a series of rays from this point to the input model. The distance from the observation point to the intersection is summed over for all the angles studied giving a compound isovist measurement for the grid square under consideration.

title	A Computational Framework for Theater Design
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. 165-182
summary	This paper presents the results of an ongoing research on computational methods for the design of theatrical spaces. We demonstrate a systemic approach to design supported by a set of digital tools implemented for assisting the process. The primary purpose of the framework is to establish a formal basis for expressing and exploring explicit design criteria. At this stage the framework enables us to metrically access a range of design metrics that traditionally have been addressed through primarily architectural narrative. Moreover, our method strives in establishing a background where knowledge can be explicitly encoded and the results of analytical methods can be additively employed. In the future, the framework will assist as the platform for experimenting with generative or query-based design processes empowered by computation. We structured this paper / framework around three conceptual units: (a) a design intent toolkit assisting the processes of rapidly generating theater configurations; (b) an analytical system that evaluates a range of design metrics centered about aspects of visual comfort; and (c) a post-processing and visualization unit that binds the design metrics with existing data / studies and provide a range of representation methods. Overall, the methodology adopts existing knowledge in theatrical design, challenges traditional ideas of understanding the theater and proposes methods for evaluating its architectural performance. The conclusions focus on highlighting both the limitations and the potential of our system in the process of theater design. We also extend outside the boundaries of the current research into a brief discussion on the methodological impact of digital technology in architectural research. Finally we propose areas of future research and development.

summary	The purpose of this study is the development of a tool by which citizens who are non-specialists can design a regional revitalisation project. Therefore, a 3D CAD / VR (3-dimensional computer-aided design / virtual reality) combination system was developed by using SketchUP Pro, GIMP, and UC-win / Road. This system has the advantages of low cost and easy operation. The utility of the system was verified as a result of applying the developed prototype system in the Super Science High School program for high school students created by the Ministry of Education, Culture, Sports, Science and Technology, Japan. It has been used for two years, since 2007. In addition, the characteristics of the VR made by the non-specialists were considered.

source	Proceedings of the 14th International Conference on Computer Aided Architectural Design Research in Asia / Yunlin (Taiwan) 22-25 April 2009, pp. 277-284
summary	Prototype manufacturing as an educational tool has been very successful at the college level in architecture and engineering design. This paper discusses an innovative inquiry-based learning approach rather than the problem-based learning models commonly utilized by other similar programs. For example, several research-funded technology projects (e.g., Cappelleri et al. 2007) look at involving students in problembased learning exercises (e.g., building robots); however, these exercises (while providing valuable experiences) have predetermined outcomes ingrained by the teachers, the project structure, and the components used to construct the devices. Therefore, inquisitive and creative problem solving is limited to the “kit-of-parts” in their approach to solving the problem. The inquiry-based CADCAM pedagogy model is more concerned with the process of solving a problem through the vehicle of prototyping than with the specificity of the design project itself. This approach has great potential. First, the need to solve the problem drives learning on multiple levels, integrating interdisciplinary ideas into the problem and solution. Second, the problem interlocks disciplines through inquiry knowledge building in team exercises. Finally, it encourages diversity and flexibility by allowing students to look at problems from multiples perspectives and points of view.

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	This article intends to investigate the meaning of Digital Panoramas as a tool to develop an alternative reading of the urban centralities in the city of Rio de Janeiro. We assume that Digital Panorama can bring significant contributions to urban research, in three different historical layers: at the beginning of 20th century; during the 20-40’s decades, and in the current days. The strength of panoramas in urban study is particularly enhanced by interactivity. This paper aims to demonstrate new possibilities in the association of panorama’s space recognition characteristic for historical study in urban centralities.

summary	In virtual workplace, two-dimensional system with desktop metaphor can provide only limited functions and interactions. It is indispensable to create a framework that can change traditional computer generated 3D model into interactive virtual architecture exploited by end users. However, such framework cannot be established without fundamental understanding of the new virtual architecture. The aim of this research emphasizes on how to design a virtual working place supporting actual office activities to extend the boundary of the conventional office through ‘Digital Space Lab’ case study. To achieve our goals, potential usability of virtual architecture is investigated. The next step is to design the virtual working place. After that, a set of scenarios indicating how the end users will utilize our interactive workplace is demonstrated. Eventually, the result serves as basis knowledge to construct a usability framework for the novel virtual architecture.

title	Location Based Services in Revitalization: The Use of Commonly Available Techniques for a Client-Participation Model
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. 505-516
summary	This research concentrates on the combination of remote sensing devices, georeferenced data, web-based optimization techniques and Location Based Services in revitalization. Its aim is to enhance the delivery of information about the development potentialities of existing buildings. The present and idle stock of buildings is extensive. Nonetheless, significant data and information about existing buildings is hardly available. The real estate owners are usually not known by prospective clients and they can be elicited only with substantial effort. But even if data about a building is available it is difficult to valuate it precisely, because of missing standard classification techniques. The question whether or not a building is suitable for a certain subsequent use is therefore hard to answer. It involves an extensive expenditure of time and manpower. Recent publications however, demonstrate that requests for the re-use of buildings can be solved through the use of combinatorial optimization techniques (Loemker 2006a, 2006b, 2007). Within these approaches researchers mainly concentrate on the architect dealing with inquiries from clients. These inquiries typically address the question if specific buildings are suitable for particular future uses. With the aid of optimization engines the architect can solve these requests through a description of the existing buildings and the corresponding enquiries in terms of specific criteria such as number and size of rooms or adjacency between rooms. According to an unambiguous syntax these approaches can be applied to any building type. The building data is stored in databases which can be inquired through optimization engines which thereupon calculate suitable solutions to the demands made by the client. But even if these approaches demonstrate high potential, their bottleneck lies in the exclusive use through the architect. Neither can they be addressed to buildings that are not listed in the architects own inventory listings nor can they be used by the clients themselves. Furthermore, no reliable statement about a prospective reuse of a building can be made directly on site by prospective clients, i.e. buyers or renters. In our research we examined if ad-hoc analyses of existing buildings can be accomplished through the clients themselves with the aid of Location Based Services that can be accessed by common remote sensing devices. The aim is to give prospective clients the possibility to visit a building and run in-situ usability simulations. To accomplish this, building data will be transferred between the building and the client through the use of ordinary communication devices. These devices automatically connect to server-based applications, which compare the requirements of the client with the existing building and run remote simulations on concrete further utilization. The newly generated information will then be passed back to the client’s device. In the paper we address a scenario of a prospective client who visits a city where he hits on an unused building he might be interest in. The client wishes to gain immediate and accurate information if the building is able to meet his demands regarding the space needed for his company. Different techniques investigated, their assets and drawbacks will be described that could accomplish suchlike tasks.

summary	This paper reports on the findings of an empirical investigation into the impact of different media on design methodology. The statistical sample included 49 fourth year architecture students, divided into three groups: the drawing group, the physical model group and the computer group. They were given a problem of designing a façade in an urban context in Glasgow over a two week period. The design process of each group was monitored over that period through observations, recordings and attitude measurement via a questionnaire survey. The results were analysed using the Statistical Programme for Social Sciences (SPSS). The dendrograms from cluster analysis revealed that there were well established perceptual dimensions, or clusters, for the façade’s design variables within the three groups because of using different media. The impact of media on design creativity, both as a process and a product, was investigated. All three media types yielded a positive correlation between ‘media made design decisions more creative’ and ‘media made design scheme more creative’- with a correlation coefficient of 0.708 which was significant at the 0.01 level, p<0.05.

title	Designing with images: Augmented reality supported on-site Trompe l’oeil
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. 275-290
summary	Activities in the building industry in Germany concentrate increasingly on a combination of renovation and new-build. A look at current computer aided applications reveals a serious lack of IT support for the whole architectural design process with and within existing buildings (e.g. building surveying, designing on site and the preparation of information for further use in later planning stages). An ongoing interdisciplinary research project undertaken jointly by the faculty of media and the faculty of architecture is investigating methods and techniques for the computer-aided support of the design process with and within existing buildings. The goal is to develop a hardware and software concept for a “design-toolbox” based on SAR (spatial augmented reality) and to implement aspects of it as prototypes. The paper focuses on one aspect of the research project – designing with images in an AR-Environment. The paper presents an overview of the project, a description of the core model based on a client-server architecture, the historical / theoretical architectural background and first results of this research part. The project is funded by the “German Research Foundation (DFG)”.

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.
