title Otimização geométrica de superfícies de fachada para uso fotovoltaico [Geometric optimization of facade surfaces for use of photovoltaic]
source SIGraDi 2012 [Proceedings of the 16th Iberoamerican Congress of Digital Graphics] Brasil - Fortaleza 13-16 November 2012, pp. 426-430
summary This work describes a methodology to optimize solar incidence in photovoltaic facades of multi-floor buildings. The methodology identifies and parameterizes the building volume according to geometric principles of photovoltaic capture for all facades orientations. Initially, geometric modeling is made through an algorithm developed in a graphic-algorithm editor, Grasshopper – integrated with the modeling tool, Rhinoceros – then establishing the shape restrictions and variables. Secondly, twist and taper geometric transformation is correlated with solar incidence data through the interface of genetic platform, Galapagos. The results indicate that it’s possible explore the method to obtain: optimal solutions, reduced design time and better energy performance.

summary 2D GIS has shown its limitations in many situations, especially when it’s applied in urban design. Many studies have been carried out to deal with the problem. Some attempted to link 3D visualisation to data stored within 2D GIS, and others tried to combine GIS, CAD and visualisation together. They all aim to meliorate current GIS for 3D applications. The authors of this paper developed a preliminary prototype of a 3D urban space information system based on Google Earth Plugin. It sets up a server to store and offer specific urban space information. With the desktop application that embeds Google Earth Plugin, user can upload and download models on the server, view them in the virtual 3D environment of Google earth, and make models directly in the 3D environment. A server-side database plays the role of managing information. This paper introduces the key ideas and methods of the system development, including system structure, set-up of the serve, server side information management, and interactive modelling functions.

summary The article presents a graph-based spatial analysis toolset (“decoding spaces”components) which we have recently developed as an extension of the visual scripting language Grasshopper3D for Rhino. These tools directly integrate spatial analysis methods into CAD design software which can have a signifi cant effect on current design workfl ows. However,grasshopper doesn’t only enable the results of analyses to be used in the standard Rhino modelling environment. It also makes it possible to integrate spatial analysis into a parametric design approach as discussed in this paper. The functionality of this toolset is demonstrated using a simple urban design scenario where we introduce the idea of parametric patterns based on graph-measures.

title Three Dimensional Reconstitution of an Old Town from Historical Documents: Case of the Medina of Jijel in Algeria
source CAAD | INNOVATION | PRACTICE [6th International Conference Proceedings of the Arab Society for Computer Aided Architectural Design (ASCAAD 2012 / ISBN 978-99958-2-063-3], Manama (Kingdom of Bahrain), 21-23 February 2012, pp. 191; 285-303
summary The three-dimensional reconstitution of cities and urban tissues was the subject of several studies and researches. In order to obtain the acquisition of the geometry of architectural or urban sets, some studies are based on Photogrammetric or on computer vision. Others have focused on the development of tools of acquisition from a laser providing a 3D scatter plot. Some of them yet focused towards the development of CAD software. The automatic generation for morphological 3D representation based on the exploitation of the architectural knowledge basis is also an option. This type of work becomes more relevant and legitimate when it concerns old cities in state of ruin or more simply missing whose remains only prints or literary descriptions similar to our case study; the old town of Jijel that many people ignore its existence. The aim of this work is to achieve a 3D reconstitution of buildings of this town based on historical documents, mostly prints, digitized old maps and plans, as well as literary texts (tales of travelers, military records, and history books). The method developed can solve and generate possible urban volumes in the most frequent cases. The 3D model obtained, despite its geometric simplicity, can view the city from different angles and open new opportunities for research in history, architecture and town planning.

summary This article refl ects on the digital reconstruction of the Vinohrady Synagogue in Prague, which was demolished in 1951. Based on an international collaboration through the Erasmus program, expertise derived from other Viennese synagogue reconstructions at TU Vienna was combined with a resource organization methodology developed at KU Leuven. The reconstruction process is carried out using BIM software, which poses some particular attention on the software methodology and model structure, but at the same time illustrates the added value of a BIM approach, when comparing with more traditional CAD modelling systematics. Of particular interest is the approach for modelling complex geometry, integrating with more traditional 2D documents and for visualizing reconstruction assumptions within the 3D model representation.

summary This paper evaluates the use of Scan-and-Solve plug-in for structural analysis in Rhinoceros’s environment. A reception desk parametrically modeled was evaluated with Scan-and-Solve and with Ansys. From the results, we concluded that the main difference between the programs is that Ansys allows more detailed definition of the connections between parts of the object. Besides the virtual models, the results were showed with a physical model printed with the rapid prototypes techniques. The paper describes the integration of parametric modeling, structural analysis and rapid prototyping procedures in the design process.

summary In the fabrication of organic free-form shapes in architecture one is constantly faced with specifi c planning and design challenges. This paper examines these problems as well as possible solutions for the design of a completed and built prototype using the example of an organically shaped pavilion made of glass fi bre reinforced plastic modules. The paper describes which adjustments to the original design were required to take the step from “digital physicality” to “physical digitality” to realize a constructive and economically successful implementation. The solutions discussed combine modern digital software methods such as parametric design with innovative 3D modelling principles.

title Real-time rendering of large building information models: Current state vs. state-of-the-art

summary With the use of Building Information Models (BIM), real-time 3D visualisations have become a natural tool in order to communicate ideas and share information between all involved parties in a project. Currently, several different BIM viewers are available for the purpose of interactive presentations and design reviews. However, as BIMs become larger and more detailed, it provides a challenge for available software solutions to manage them interactively. In this paper we present our findings from analysing three commonly used BIM viewers - Tekla BIMSight, Autodesk Navisworks and Solibri Model Viewer - in terms of real-time rendering performance. In addition we have developed a prototype BIM viewer to test modern approaches for efficient real-time rendering. Specifically, we have implemented the latest version of the Coherent Hierarchical Culling algorithm. Our results show that existing BIM viewers all share limitations in their ability to handle large and complex BIMs interactively. However, for the same test models, our prototype BIM viewer enables smooth real-time performance with no visual artefacts. The results from our tests thus shows that the technology to enable correct real-time rendering of large and complex BIMs is already accessible, but are currently not utilised by any of the tested BIM viewers.

summary Volume rendering is an illustration technique for visualising different 3D measured data or 3D simulation data interactively on screen. This paper introduces a method that overlays several types of volume data on an architectural surface model. This complex calculation takes place on the graphics card using hardware-accelerated shaders. An implemented software prototype entitled “VolumeRendering” is introduced. In addition to interactive visualisation, the objective was to create a user-friendly interface. Synergies and new evaluation possibilities arise through the overlay, e.g. of different measuring techniques, with a surface model. Finally the use of the software prototype is illustrated using examples from our interdisciplinary research project.

summary Architects have been using computers for documentation but they are yet to engage them within a process designing that goes beyond basic representation. This paper explains a project that explores an alternate way computers could be unitized in architecture. More specifically, for the creation of mass customizable homes whose design quality can be controlled through the use of shape and grammar based rules that reliably produce controlled variation with its structure. The ultimate goal of the project was to develop a prototype within the parametric software grasshopper. The development of this project was based on the idea that homebuilders could engage this type of tool to deliver better products that could be custom tailored for their clients and architects could utilize within their design process.

summary It is noted that architects need new and quick methods designing the historic architectural styles, as well as restoring the historical urban areas particularly the Islamic ones. These designs and restorations should adapt to the basics of the Islamic style used; general concept, module and features. Smart Geometry provides advanced design concepts and increases alternative variations. Parametric design softwares also add more rules and relations on the design process. Obviously, the Islamic module and proportions are used as design generators that result in extracting a number of alternatives easily in a little time. Generative Components (GC) is the parametric software used to achieve the desired objectives of this research.

summary Physical Digitality is the second volume of the conference proceedings of the 30th eCAADe conference, held from 12-14 september 2012 in Prague at the Faculty of Architecture of Czech Technical University in Prague. The companion volume is called Digital Physicality. Together, both volumes contain 154 papers that were submitted to this conference. Digitality is the condition of living in a world where ubiquitous information and communication technology is embedded in the physical world. Although it is possible to point out what is “digital” and what is “real,” the distinction has become pointless, and it has no more explanatory power for our environment, buildings, and behaviour. Material objects are invested with communication possibilities, teams are communicating even when not together, and buildings can sense and respond to the environment, each other, and to inhabitants. Digital is no longer an add-on, extra, or separate software. Reality is partly digital and partly physical. The implication of this condition is not clear however, and it is necessary to investigate its potential. New strategies are necessary that acknowledge the synergetic qualities of the physical and the digital. This is not limited to our designs but it also infl uences the process, methods, and what or how we teach. The subdivision of papers in these volumes follow the distinction made in the conference theme. The papers in Physical Digitality have their orientation mainly in the physical realm, and reach towards the digital part. It has to be granted that this distinction is rather crude, because working from two extremes (digital versus physical) tends to ignore the arguably most interesting middle ground.

summary In this era, Architectural Design Practice is faced with a paradigm shift in its conventional approaches towards computational methods. In this regard, it is considered a pedagogic challenge to boost up knowledge and skills of architectural students’ towards an advanced approach of architectural design that emphasizes the potentials and complexity of computational environments and parametric tools for design problem solving. For introducing the concept of Parametric Oriented Design Methods to 3rd year level architectural students, an experimental pedagogic course was designed in the scholastic year of 2012-2013 at German Jordanian University GJU (School of Architecture and Built Environment SABE) to approach this concept. In the preparation phase, the experimental course was designed to incorporate structured instructing and training method to be consecutively performed within experimental lab environment to target predetermined learning outcomes and goals. The involved students were intentionally classified into three levels of previous involvement associated with the related software operating skills and computational design exposure. In the implementation phase, the predetermined instructing and training procedures were performed in the controlled environment according to the planned tasks and time intervals. Preceded tactics were prepared to be executed to resolve various anticipated complication. In this phase also, students’ performance and comprehension capacity were observed and recorded. In data analysis phase, the observed results were verified and correlations were recognized. In the final phase, conclusions were established and recommendations for further related pedagogic experiments were introduced.

summary This paper investigates the relation between the shading condition and geometrical configuration of neighborhood-scale developments. It introduces a straightforward method for measuring shadow areas casted on buildings’ roofs and facades – in urban areas – using digital 3D models. Employing this method for measuring shadow areas in nine neighborhoods in Jinan, China, at six different time points on summer and winter solstices – a total of 54 sample measurements – this study develops two regression models that reveal the significant dependency of the in-shadow percentage of buildings’ façade and roof areas to the building volume density (BVD) and height irregularity (HI) of the urban fabric.

summary In this paper we present an environment for conceptual design which mimicsthe interaction of designers with physical mockups. We present novel three dimensional on-and-above-the-surface interactive techniques which combine asymmetric bimanual operations with multi-touch direct manipulation on a fl at surface and depth cameras. These take advantage of a continuous interaction space to create and edit 3D models in a stereoscopic environment. To allow modeling architectural shapes directly, we combine hand and finger tracking in the space above the table with multi-touch on its surface without the need to change modes. This provides an alternative design environment where users can seamlessly switch between interacting on the surface or in the space above it depending on the task, which makes it easier to model complex shapes using simple operations.
