title	Building Information Modelling of Modern Historic Buildings
source	Predicting the Future [25th eCAADe Conference Proceedings / ISBN 978-0-9541183-6-5] Frankfurt am Main (Germany) 26-29 September 2007, pp. 607-613

summary	This paper reports a research study which evaluated the possibilities of building information modelling (BIM) within renovation of buildings of significant architectural, historic or cultural values. Renovation or restoration projects of historic buildings can be more demanding, challenging and complex than traditional renovation of for instance within housing. Objective of this research has been to transfer ICT (information and communication technology) and BIM research findings to historic design practice and true renovation project environments. The concept of building information modelling BIM is a proposed integrative framework for all design and construction project information in digital form. BIM can currently be seen to be in a phase of pragmatic pilot projects in several countries. Nevertheless, BIM has not been tested that much in renovation projects yet, although the importance of renovation and restoration is remarkable within the total volume of western construction sectors. One essential conclusion of this study is, that renovation design work should be started earlier in model-based design projects than in traditional renovation projects. More resources have also to be assigned to earlier design phases, if BIM is intended to be used extensively throughout the project. Another finding is the new concept of an inventory model, which is proposed to be the container for all building inventory, survey and measurement data. Even more so, when significant historic, hence more demanding building renovation is concerned, because there are more needs for various kinds of surveys, accurate data gathering and analyzing queries concerning the project.

title	Co-operation and Complicity Voices, Robots, and Tricksters in the Digital Marketplace
source	International Journal of Architectural Computing vol. 5 - no. 1, pp. 162-175
summary	We advocate the theme of complicity, ahead of co-operation, as a means of understanding complex, interactive digital systems. Our case study of a market precinct known as the Barras, about one mile from the centre of the city of Glasgow, foregrounds the notion of complicity. Market places are characterized not only by co-operation in rule-governed environments, but complicity between actors as a means of breaking rules, working at the boundaries of formal frameworks, avoiding other actors, such as law enforcers, and even working with them in tacitly agreed evasion strategies. We present the human voice (as exercised in the case of market stall holders drawing attention to their wares) as a major medium of complicity. In our application of these ideas we deploy Lego Mindstorms TM RCX robot processing to explore interactions between a mobile sensing robot and simple environmental controls: movements of sliding screens in response to an autonomous mobile sensor. As well as their benign characteristics as co-operating agents, we argue for a consideration of robots as quintessential tricksters, plotting and scheming strategies of survival, evasion and opportunism. Traits that can be employed in the development of useful augmented environments.

title	RQS - Reverse Quadratura for Surveying

summary	This research is based on the development of a new method for surveying single and double curved surfaces using an application of an ancient perspective method for representing a picture on a complex surface. The procedure enables the user to have some detailed cross-points of a grid in order to simplify the survey operation. Another phase of the work is to take some double-pictures of the element, according of the method I shall describe in the paper. The photographs of the single element, with the projection of the regular grid, can be processed with every Image-Based Modeling Software in order to obtain – with the usual calibration methods – the digital “mapped with reticulum” model of the curved surface we are analyzing. The final step enables the user to improve the quality of the textured model, switching from the grid-textured photographs to the simple-textured one. This research is part of a more general theoretical and experimental Academic research that has the aim of studying the ancient drawing methods of in order to find some analogies with the digital technology applied to the study of architectural buildings.

title	Detailed 3D Modelling of Castles
source	International Journal of Architectural Computing vol. 5 - no. 2, pp. 200-220
summary	Digitally documenting complex heritage sites such as castles is a desirable yet difficult task with no established framework. Although 3D digitizing and modelling with laser scanners, Photogrammetry, and computer aided architectural design (CAAD) are maturing, each alone is inadequate to model an entire castle in details. We present a sequential approach that combines multiple techniques, each where best suited, to capture and model the fine geometric detail of castles. We provide new contributions in several areas: an effective workflow for castle 3D modelling, increasing the level of automation and the seamless integration of models created independently from different data sets. We tested the approach on various castles in Northern Italy and the results demonstrated that it is effective, accurate, and creates highly detailed models suitable for interactive visualization. It is also equally applicable to other types of large complex architectures.

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	BIM as a Viable Collaborative Working Tool: A Case Study
source	CAADRIA 2007 [Proceedings of the 12th International Conference on Computer Aided Architectural Design Research in Asia] Nanjing (China) 19-21 April 2007
doi	https://doi.org/10.52842/conf.caadria.2007.x.l1j
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.

title	Team-Working and Reverse Engineering: Teaching Methods for Complex Architecture
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. 343-356
summary	This paper contains research and details of a work in progress on the implementation of advanced 3D precision modelling in an undergraduate curriculum. Core to the investigation is the undergraduate course Digitally Enhanced Construction and Fabrication (D.E.C.A.F.) at the Department of Architecture, California State Polytechnic University Pomona. The course tests the application of Reverse Engineering (RE) in a team configuration, Hot-Swapping (HS), and precision modelling of complex geometries with minimal programming/scripting input, taking in consideration the limited resources common to small-scale architectural practices. Reverse Engineering particularly enables students to extract information building assembly and executed details with precision, based on existing documentation. It is conducted in teams not only to emphasize and investigate efficiency of protocols but also to observe problems in developing threads in digital modelling. Hot-Swapping identifies the principle of replacing components of a building during active design processes without altering its general appearance. As a teaching methodology, it allows the investigation of required modelling accuracy, creation of prototypes and various versions of assembly alternatives. The current paper focuses mainly on 1) engaged procedures in Reverse Engineering, 2) the educational aspects of such an approach, and 3) the advantages and disadvantages of conventional tools in a collaborative modelling exercise.

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.

summary	“Ce n’est point le navire qui naît de la forge des clous et du sciage des planches. C’est la forge des clous et du sciage des planches qui naissent de la pente vers la mer et croissance du navire” (Saint-Exupéry, 1948). The paper describes and analyses a course held at Stuttgart University, Germany dealing with the application of parameters in an architectural design process and the transformation of this process into a relational digital model. The course is introduced with special emphasis on its tasks, aims and the implicit didactic concept. It is also investigated if and how a design approach resulting from the identification and determination of parameters can lead to a creation of a unique shape. Finally the impact of the practical exercises for the final design is evaluated. The course’s structure is enhanced by the “Vorklasse” from Bauhaus and the conviction that using software is taught most effectively by working on an own specific project. At the very beginning the students get the chance to gain experiences with parameters through preliminary practical exercises, like folding and modelling and analysing. Then the use of the software is taught in several compact sessions in parallel to the design process. The impact of the early practical exercises on the subsequent design process is remarkable. Special attention is therefore given to this aspect. The aim of the lessons is to produce a proposal for the design task. The proposal is then to be presented as a parametric model representing either the global shape or a constructive detail.

title	Structural Analysis as Driver in Surface-based Design Approaches
source	Predicting the Future [25th eCAADe Conference Proceedings / ISBN 978-0-9541183-6-5] Frankfurt am Main (Germany) 26-29 September 2007, pp. 109-115
doi	https://doi.org/10.52842/conf.ecaade.2007.109
summary	This ongoing research argues for novel strategies to integrate structural analysis data in an architectural design approach. Instead of a linear procedure of synthesis, analysis and post-rationalisation a synthesis/analysis loop is installed that uses structural analysis data as design driver from early on. The approach is not aiming for a pure force-driven form-finding or optimization process but regards structural performance as one design criteria among others. Equilibrium between multiple parameters is aspired instead of a single-parameter-optimum. The research is conducted by a custom-made digital interface between a 3d modelling software and an application for structural analysis of space frames structures. Surfaces are translated into meshes with supports at user-defined nodes and then exposed to its dead load in the structural analysis software. The resulting nodal deviation is feed into an algorithm that steers the appropriate reaction towards the local stresses and deviations, taking into account the mesh topology, its supports and their position in the mesh. The initial mesh is optimized in shape transformed back into a double-layer surface model in the 3d software which evolves into an interconnected two-layer space frame. An instant feedback from synthesis to analysis and vice versa is installed. Analysing techniques migrate into the realm of synthesis.

source	SIGraDi 2007 - [Proceedings of the 11th Iberoamerican Congress of Digital Graphics] México D.F. - México 23-25 October 2007, pp. 364-369
summary	Pedestrian simulation tools are usually used to evaluate pedestrians’ evacuation/security in buildings (closed environments). The paper’s objective is to develop a methodology for the application of these tools in urban planning (open spaces), where the pedestrian behavior is more complex. The area studied is Plaza Baralt, in Maracaibo Venezuela, an area enclosed by historic buildings. The proposed scenarios and pedestrian flow simulations – based in cellular automata – followed a locally adapted data recollection and site analysis. As a result the methodology allows the designer to analyze various scenarios, fast and efficiently, identifying problems of areas, flow, land use and user profiles.

title	Applying generative modeling procedure to explore architectural forms
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. 697-712
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.

summary	The spaces we live in are increasingly entwined in a complex weave of architecture and technology. With the evolution of intelligent devices that work in the background, design of place will eventually be a seamless integration of not just efficient but also experiential and virtual technologies. This signals a paradigm shift because “smart” architecture affords users a new interaction with architecture. In spite of such promises, we have seen interactive architecture ideas and “smart” environments only within laboratory walls or in the form of simplistic implementations. Perhaps the reason is simple. Rachael McCann asks if the integration of technology within the context of an increasingly information-driven modern era has abandoned the body in favor of the mind (McCann 2006). If we acknowledge that “smart” computing has the opportunity to transcend an efficient backbone to generator of experiences, perhaps we, as designers, must reconsider our position and strategy in this modern world. This paper is designed as a critical essay—one which evaluates interactive architecture and “smart” environments within the context of today’s socio-cultural climate. The paper hopes to open a discussion about the role of computing as architecture and the role of the architect in the design of such architecture.

title	Spatial Simulations with Cognitive and Design Agents
source	International Journal of Architectural Computing vol. 5 - no. 1, pp. 100-114
summary	Agent based design systems could provide useful decision help for architects working on spatial planning tasks that involve large number of actors or deal with complex urban situations. These systems are especially helpful in bridging the gap between concrete design proposals and high-level design abstractions such as frequency and flow diagrams. Every attempt to use computational design agents in the planning process will automatically raise many fundamental issues about spatial perception and representation of the environment. The paper discusses these issues in the light of some recent agent based simulations. Two case studies are presented in order to demonstrate different uses of computational agents in urban design. The first study shows how a simple agent-based design system placed in an urban context becomes a creative production tool. The second one reveals analytical capabilities of an agent system in urban environments.

summary	Normally, academic applications of computer-aided design in building project provide a visual presentation of the final state of the house and they are not able to produce changes in the geometry following the construction process. It was developed a didactic prototype that allows the visualization of the physical changes of the construction of a common external wall. In order to obtain models, which would be able to visually simulate the geometric evolution of the construction activity, techniques of geometric modeling and virtual reality were used. The visualization of the distinct physical steps of a construction is shown as 3D models following a specific planned schedule. The model makes it possible to view the physical evolution of the work, to follow the planned construction sequence and to visualize details of the form of every component of the works. It can be manipulated interactively allowing the student/teacher to monitor the physical evolution of the work and the construction activities inherent in its progression. The developed model brings new perspectives in the teaching activity as a support to expose new curricular programs or complex sequence construction.

title	The Categorisation of Data from Smart Buildings for a positive Sustainable Application
source	CAADRIA 2007 [Proceedings of the 12th International Conference on Computer Aided Architectural Design Research in Asia] Nanjing (China) 19-21 April 2007
doi	https://doi.org/10.52842/conf.caadria.2007.x.h3i
summary	This paper describes an architecture oriented approach of a categorization of information in so called computer integrated buildings (CIB). It follows an approach which seeks for the suitability of information categorization in order to achieve an energetically sustainable operation of CIBs. The CIB and its environment may exist as physical objects or as a simulation. The underlying question of this paper is: how can data of high temporal and spatial density be made accessible within a CIB with the goal of quickly delivering the most suitable answers for a specifical application. The subtitle „Google™ in the House“ was chosen due to the achievable relation of a model with simple user interfaces, extendable pre-valuable data basis and high quality answers is being developed. The model’s foundation is the potential of any built context that it is very easy to position data in physical space by adding its position by Cartesian coordinates. This architectural way of pre-sorting data is defined as logical arranging. Further on, known mechanisms of information retrieving and mapping are added to the model. A preliminarily summary concludes that energetically sustainable operations are backed through means of computational categorization models.

summary	This paper presents a novel approach for the automatic creation of vegetation scenarios in real or virtual 3D cities in order to simplify the complex design process and time consuming modeling tasks in urban landscape planning. We introduce shape grammars as a practical tool for the rule-based generation of urban open spaces. The automatically generated designs can be used for pre-visualization, master planning, guided design variation and digital content creation in general (e.g. for the entertainment industry). In a first step, we extend the CGA shape grammar by Müller et al. (2006) with urban planning operations. In a second step, we employ the possibilities of shape grammars to encode design patterns (Alexander et al., 1977). Therefore, we propose several examples of design patterns allowing for an intuitive high-level placement of objects common in urban open spaces (e.g. plants). Furthermore, arbitrary interactions between distinct instances of the vegetation and the urban environment can be encoded. With the resulting system, the designer can efficiently vegetate landscape and city parks, alleys, gardens, patios and even single buildings by applying the corresponding shape grammar rules. Our results demonstrate the procedural design process on two practical example scenarios, each one covering a different scale and different contexts of planning. The first example illustrates a derivation of the Garden of Versailles and the second example describes the usage of high-level rule sets to generate a suburbia model.

summary	This paper introduces a practical approach to constructing a hybrid 3D metrical–topological model of a university campus or other extended urban region from labeled 2D floor plan geometry. An exhaustive classification of adjacency types is provided for a typical infrastructure, including roads, walkways, green-space, and detailed indoor spaces. We extend traditional lineal techniques to 2D open spaces, incorporating changes in elevation. We demonstrate our technique on a dataset of approximately 160 buildings, 800 floors, and 44,000 spaces spanning indoor and outdoor areas. Finally, we describe MITquest, a web application that generates efficient walking routes.

summary	Kinetic structures offer the means to significantly expand the functional and performance features of traditionally static architectural solutions. However, the added element of motion creates considerable challenges during conceptualization and introduction into existing design workflows. Rigidly foldable shells offer tremendous potential for developing kinetic architectural structures. They require few support points, eliminate sliding overlaps and are relatively easy to mock up as initial concepts. Achieving the desired motion range, however, requires a significant design effort. If performed manually, the motion optimization is tedious and unpredictable. This paper examines possible optimization algorithmic strategies with the use of fuzzy logic. Specifically the paper focuses on the application of fuzzy logic as a tool for effectively negotiating modifications of complex linked geometries while using intuitive, high level statements and directives. Highlighted is the potential of fuzzy logic-based algorithms as tools that can help the transition of existing design workflows into environments that can handle extended challenges involving kinetic geometries.
