summary	The paper has two targets: a theoretical and a practical one which are totally dependant on each other: Its first purpose is to prove based on detailed comparative study by use of competent software apparatus that rotation in a building abiding by strict rules of adaptation to environmental changes (climate, season, time of day, sun duration etc.) should be viewed by modern architecture as a sine-qua-non in terms of energy consumption economy, environmental resources protection, achievement of high standards of living in the city. The aforementioned benefits will be evidenced by means of comparison of responsive structures to traditional ones. The second and most important purpose is to elaborate and provide the fundamental data and information for the creation of a supporting software for the above described model. The two in interaction will result in “revolution” in modern architecture.

summary	To address the shortcomings of integrating building simulation in architectural design and to make it more appealing to students, a simple interface to Energyplus was created. This interface models a simple rectangular building that is passively heated by direct gain and cooled by ventilation. A simple photovoltaic interface has also been added to supply fan energy. This tool has an OpenGL modeler for visualization and uses Energyplus for calculations. The interface will run a full year simulation and graph the results. The results are reported in a yearly graph that shows the outdoor and indoor temperature. The indoor temperature range is based on adaptive comfort level. The interface was tested and used in an introductory design studio in order to comply with the 2010 imperative. The students simulated a simple box and changed the buildings parameters until the building fell within the adaptive comfort zone for most of the year. The climate simulated was Chicago, IL. Using these parameters the students then designed the building. The resulting designs show that even though the students were restricted in parameters, such as window percentage, they were still able to creatively design unique buildings that use zero to negative net energy for heating and cooling in a climate such as Chicago.

title	Situated Bioclimatic Information Design: a new approach to the processing and visualization of climate data
doi	https://doi.org/10.52842/conf.acadia.2010.088
source	ACADIA 10: LIFE in:formation, On Responsive Information and Variations in Architecture [Proceedings of the 30th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-1-4507-3471-4] New York 21-24 October, 2010), pp. 88-96
summary	Currently, most approaches to graphic evaluative frameworks (GEFs) for the early-stage evaluation of bioclimatic design strategies adopt a design-tool metaphor, wherein a battery of analytical routines is performed by a software tool based upon a standardized weather file from which a stock set of graphic material is produced. In seeking to evaluate a broad range of climates and to address a wide variety of passive design strategies, existing climate visualization and evaluation tools position themselves far outside of the context of a situated design problem. Remaining agnostic to the particularities of site, program, tectonic system, and material behavior these tools become, by definition, generic. As a consequence, while such design-tools can be effective in evaluating particular relationships between environmental resource, demand profile, and built-system, they maintain a potential to be rendered ineffective in any outlying cases not specifically anticipated by their authors . Situated Bioclimatic Information Design (SBID) presents an alternative approach that targets a class of design strategies prominent among these outlying cases: those highly responsive to negotiation between the continually fluctuating resources within microclimates and the fluctuating demand profile of the building program. Using a custom-built weather data parser a number of diagrams and data visualizations have been produced under this approach. These visualizations are not only useful in and of themselves for aligning design strategies to specific contexts, but they also illustrate the foundations of a larger theoretical framework for the processing and visualization of climatic data for effective utilization of bioclimatic flows.

doi	https://doi.org/10.52842/conf.acadia.2010.305

summary	The instrumental and aesthetic implications of architecture’s engagement with science and technology has a long history, part of which includes the period following the Second World War when the rapid technological advances of the Industrial Revolution merged with a general cultural mindset characterized by themes of progress and futurism. For postwar thinkers like Reyner Banham, this interest in a futurist architecture suggested an approach to design rooted less in architectural precedent than technological extrapolation. While a precedent based approach might be viewed as more disciplinary in nature, technological extrapolation suggests an inclination towards interdisciplinarity. Thus, Banham’s concept of extrapolation encouraged architects to look beyond the limits of their own discipline as a means of discovering new forms of knowledge and expertise. Indeed Banham was engaged in taking stock of the technological advances particular to his time while simultaneously anticipating the implication of these advancements for the future. To this extent, the postwar period and its inherent futurism provides a useful and poignant lens through which to take stock of our own technological climate. Given the equally revolutionary advances in computer technology in the last twenty years, our contemporary moment can be seen as having many parallels with the postwar period, and not unlike the postwar generation of architects and thinkers, contemporary designers are inevitably faced with the challenge of engaging new technological advances and their implications for architecture. In our current age of digital and biological technologies, these advances are both rapid and widespread, and include LED and fiber-optic lighting systems, motion sensing, interface design, solar tracking photovoltaic skins and wind harnessing technologies, magnetic levitation, and robotics. This paper begins with an examination of design work and criticism from the postwar period and proceeds to utilize that examination as an historical framework for addressing issues of contemporary design and 21st Century technological advancement.

title	Parametric Design of the Vela Roof
source	CAAD - Cities - Sustainability [5th International Conference Proceedings of the Arab Society for Computer Aided Architectural Design (ASCAAD 2010 / ISBN 978-1-907349-02-7], Fez (Morocco), 19-21 October 2010, pp. 231-240
summary	Due to the increased request for representative structures and for spaces to be used independent of the weather conditions, contemporary cities increasingly integrate public covered spaces (shadowed squares and streets, courtyards, historic commercial galleries, etc.) in the urban fibre. Facing the design of large roof structures for semi outdoor spaces is increasingly common for architects and engineers. When focusing on large roofs, aesthetics, structural performance and economics often dominate the design process. However, the current increased emphasis on energy-related aspects generates new challenges. Particularly, the use of renewable energy resources needs to be confronted. In this paper we will address the subject through a case study whose design aimed at integrating performance evaluations in the very early stages of the process. The case study focuses on the so-called “Vela roof”. This roof is part of a larger project currently under construction in Bologna (Italy). The focus of the study concerns the use of on-site renewable climate (energy) resources with special attention given passive reduction of summer overheating and daylight. For these tasks a parametric model was developed to support the decision making process and the paper will present its potential with respect to performance-oriented design during the conceptual design phase of roof structure. The very first conceptual design developed by the architectural office was assumed as a starting point for the inclusion of performance criteria. In the preliminary design of the roof uncomfortable conditions were expected under the whole roof in the summer. Various strategies for improving the thermal comfort were investigated, involving a large set of combined systems. Not all of these will be detailed in this paper. Instead we will focus on the ones directly affected by the geometry of the roof. Those are mainly air flow for cooling and the reduction of solar gain, in combination with their effects on daylight. Their investigation was based on a chain of dependencies to be integrated in the design process. With respect to that, parametric modelling was used. Parametric modelling allows both geometrical entities and their relationships to be represented. These relationships are structured in a hierarchical chain of dependencies, established during the preliminary parameterization process. The independent properties of the model are usually expressed through independent parameters, and their variations generate different configurations of the model. By making use of this potential, three project scales were parametrically explored. At the large scale, parametric variations of the overall shape of the roof were investigated in relation to cooling through ventilation and here the parametric model allowed for the generation of both different configurations of the roof, including its structural morphology and variations of its structural tessellation. At the medium scale, the integration of openable modules was investigated in relation to air extraction for cooling; with respect to this, the parametric model allows exploring openings based on variations of size and distribution. At the small scale, various options were explored for the cladding system, in order to reduce the direct solar gain while still allowing the income of indirect natural light. The parametric model was used to investigate the configuration of self-shading modules and their integration in the structure. Specific emphasis will be given to the small scale. The advantages in design process and the current limits of the parametric modelling approach used here will be discussed in the paper.

title	Algorithm Aided Architectural Design (Aaad)
source	CAAD - Cities - Sustainability [5th International Conference Proceedings of the Arab Society for Computer Aided Architectural Design (ASCAAD 2010 / ISBN 978-1-907349-02-7], Fez (Morocco), 19-21 October 2010, pp. 117-126
summary	Algorithm Aided Architectural Design (AAAD) is considered a second paradigm shift in the Architectural design process after the first one of bridging the conventional design process to the digital realm of design. This paper is divided into two parts, the first part comprehends the Algorithmic Architecture approach of from the point of view of tools, techniques, theories and practice in order to find the Algotecture theories on the map of Digital Architecture. Then, the paper exemplifies an application on Algorithmic Architecture. FALLINGWATER TOOLBOX VERSION 1.0 is a computational design demo tool for architects to aid in the house schematic design phase according to an analytical study of Frank Lloyd Wright's basic design rules and spatial program of his masterpiece; FallingWater House, (Edgar J. Kaufmann family house 1939). These rules have been transferred to algorithms and code thereafter. At a preceding stage, the Graphical User Interface (GUI) was developed using MAXScript 9.0. Using the FALLINGWATER TOOLBOX, infinite number of house prototypes can be generated within few minutes. Although, the FWT is based on a hypothetical design problem of producing prototype alternatives for a new house with the same identity of the Edgar Kaufmann House, the concept of the tool can be applied on a wider range of problems. It may help generating prototype alternative solutions for residential compounds design according to the required constraints.

title	Automated Cost Analysis of Concept Design BIM Models
source	Computer Aided Architectural Design Futures 2011 [Proceedings of the 14th International Conference on Computer Aided Architectural Design Futures / ISBN 9782874561429] Liege (Belgium) 4-8 July 2011, pp. 403-418.
summary	AUTOMATED COST ANALYSIS OF CONCEPT DESIGN BIM MODELS Interoperability: BIM models and cost models This paper introduces the automated cost analysis developed for the General Services Administration (GSA) and the analysis results of a case study involving a concept design courthouse BIM model. The purpose of this study is to investigate interoperability issues related to integrating design and analysis tools; specifically BIM models and cost models. Previous efforts to generate cost estimates from BIM models have focused on developing two necessary but disjoint processes: 1) extracting accurate quantity take off data from BIM models, and 2) manipulating cost analysis results to provide informative feedback. Some recent efforts involve developing detailed definitions, enhanced IFC-based formats and in-house standards for assemblies that encompass building models (e.g. US Corps of Engineers). Some commercial applications enhance the level of detail associated to BIM objects with assembly descriptions to produce lightweight BIM models that can be used by different applications for various purposes (e.g. Autodesk for design review, Navisworks for scheduling, Innovaya for visual estimating, etc.). This study suggests the integration of design and analysis tools by means of managing all building data in one shared repository accessible to multiple domains in the AEC industry (Eastman, 1999; Eastman et al., 2008; authors, 2010). Our approach aims at providing an integrated platform that incorporates a quantity take off extraction method from IFC models, a cost analysis model, and a comprehensive cost reporting scheme, using the Solibri Model Checker (SMC) development environment. Approach As part of the effort to improve the performance of federal buildings, GSA evaluates concept design alternatives based on their compliance with specific requirements, including cost analysis. Two basic challenges emerge in the process of automating cost analysis for BIM models: 1) At this early concept design stage, only minimal information is available to produce a reliable analysis, such as space names and areas, and building gross area, 2) design alternatives share a lot of programmatic requirements such as location, functional spaces and other data. It is thus crucial to integrate other factors that contribute to substantial cost differences such as perimeter, and exterior wall and roof areas. These are extracted from BIM models using IFC data and input through XML into the Parametric Cost Engineering System (PACES, 2010) software to generate cost analysis reports. PACES uses this limited dataset at a conceptual stage and RSMeans (2010) data to infer cost assemblies at different levels of detail. Functionalities Cost model import module The cost model import module has three main functionalities: generating the input dataset necessary for the cost model, performing a semantic mapping between building type specific names and name aggregation structures in PACES known as functional space areas (FSAs), and managing cost data external to the BIM model, such as location and construction duration. The module computes building data such as footprint, gross area, perimeter, external wall and roof area and building space areas. This data is generated through SMC in the form of an XML file and imported into PACES. Reporting module The reporting module uses the cost report generated by PACES to develop a comprehensive report in the form of an excel spreadsheet. This report consists of a systems-elemental estimate that shows the main systems of the building in terms of UniFormat categories, escalation, markups, overhead and conditions, a UniFormat Level III report, and a cost breakdown that provides a summary of material, equipment, labor and total costs. Building parameters are integrated in the report to provide insight on the variations among design alternatives.

title	Authoring Tools for KOC - Concepts and Pedagogical Use
source	International Journal of Architectural Computing vol. 8 - no. 2, 183-200
summary	One of the main problems of teachers aiming to teach the construction techniques used in to build a building is the lack of practical examples to show to their students. In order to be useful, these examples must come from real projects or even better the teachers may take their students to constructions sites, but this latter option is not always available and may be dangerous. To deal with this problem, Los Andes University has committed the construction of a knowledge repository containing information gathered from real projects and semantically described, in order to provide easy access to its content and in the language of people of construction. This project is called KOC, standing for Knowledge Objects of Construction, which uses an ontology to describe semantically the data contained in the repository. Being the pedagogical objective of the project, it is important to provide the teachers with additional tools to generate new knowledge objects, based on existing knowledge objects in the repository. This paper presents three composition tools for KOC: a complex objects composer issued from structured searches, a constructive processes composer and a case study composer, all of them aiming the improvement of learning quality in the technical area of building construction at the architecture and engineering schools. The paper also shows some examples of knowledge objects and how KOC is been used in the courses of the Architecture Department of Los Andes.

title	Automated 3D Reconstruction of Interiors from Point Clouds
source	International Journal of Architectural Computing vol. 8 - no. 1, 55-73
summary	We present a new technique for the fully automated 3D modelling of indoor environments from a point cloud. The point cloud is acquired with several scans and is afterwards processed in order to segment planar structures, which have a noticeable architectural meaning (floor, ceiling and walls) in the interior. The basic approach to data segmentation is plane sweeping based on a hypothesis-and-test strategy. From the segmentation results, the ground plan is created through cell decomposition by trimming the two-dimensional ground space using half-space primitives. An extension in height of the ground contours makes the generation of the 3D model possible. The so-reconstructed indoor model is saved in CAD format for analysis and further applications or, simply, as a record of the interior geometry.

title	Multi-touch - the future of design interaction

summary	The next major revolution for design is to bring the natural user interaction into design activities. Graphical User Interfaces (GUI) brought a new approach that was more effective compared to their conventional predecessors. In recent years, Natural User Interfaces (NUI) have advanced user experiences and multi-touch and gesture technologies provide new opportunities for a variety of potential uses in design. Much attention has been paid to leverage in the design of interactive interfaces. The mouse input and desktop screen metaphors limit the information sharing for multiple users and also delayed the direct interaction for communication between each other. This paper proposes the innovative method by integrating game engine ‘Unity3D’ with multi-touch tangible interfaces. Unity3D provides a game development tool as part of its application package that has been designed to let users to focus on creating new games. However, it does not limit the usage of area to design additional game scenarios since the benefits of Unity3D is allowing users to build 3D environments with its customizable and easy to use editor, graphical pipelines to openGL (http://unity3d.com/, 2010 ). It creates Virtual Reality (VR) environments which can simulates places in the real world, as well as the virtual environments helping architects and designers to vividly represent their design concepts through 3D visualizations, and interactive media installations in a detailed multi-sensory experience. Stereoscopic displays advanced their spatial ability while solving issues to design e.g. urban spaces. The paper presents how a multi-touch tabletop can be used for these design collaboration and communication tasks. By using natural gestures, designers can now communicate and share their ideas by manipulating the same reference simultaneously using their own input simultaneously. Further studies showed that 3Dl forms are perceived and understood more readily through haptic and proprioceptive perception of tangible representations than through visual representation alone (Gillet et al, 2005). Based on the authors’ framework presented at the last CAADFutures, the benefits of integrating 3D visualization and tactile sensory can be illustrated in this platform (Chen and Wang, 2009), For instance, more than one designer can manipulate the 3D geometry objects on tabletop directly and can communicate successfully their ideas freely without having to waiting for the next person response. It made the work more effective which increases the overall efficiency. Designers can also collect the real-time data by any change they make instantly. The possibilities of Uniy3D make designing very flexible and fun, it is deeply engaging and expressive. Furthermore, the unity3D is revolutionizing the game development industry, its breakthrough development platform for creating highly interactive 3D content on the web (http://unity3d.com/ , 2010) or similar to the interface of modern multimedia devices such as the iPhone, therefore it allows the designers to work remotely in a collaborative way to integrate the design process by using the individual mobile devices while interacting design in a common platform. In design activities, people create an external representation of a domain, often of their own ideas and understanding. This platform helps learners to make their ideas concrete and explicit, and once externalized, subsequently they reflect upon their work how well it sits the real situation. The paper demonstrates how this tabletop innovatively replaces the typical desktop metaphor. In summary, the paper addresses two major issues through samples of collaborative design: firstly presenting aspects of learners’ interactions with physical objects, whereby tangible interfaces enables them constructing expressive representations passively (Marshall, 2007), while focussing on other tasks; and secondly showing how this novel design tool allows designers to actively create constructions that might not be possible with conventional media.

summary	Increasingly, digital architectural data will become available through information technology. Yet until now, there were no satisfying methods to query this data for architectural purposes. This paper introduces an information retrieval system for parcels that not only allows searching for specific attributes, but also includes properties of shape and context of the building plots. An automatically generated index stores the relevant spatial properties as normalized bitmap images on several layers. When a query is started, only this index has to be queried and not the complete database. The search process can be controlled through a graphical interface that incorporates the user’s sketches. The retrieved parcels are presented as a sorted list of vector drawings including their contained buildings. With the simplified access to these case-studies, quality and efficiency of the architectural design process could be increased.

title	Applying augmented reality for data interaction and collaboration in BIM
doi	https://doi.org/10.52842/conf.caadria.2010.511

summary	Building Information Modelling (BIM) is expected to enable efficient collaboration, improved data integrity, distributed and flexible data sharing, intelligent documentation, and high-quality outcome, through enhanced performance analysis, and expedited multi-disciplinary planning and coordination. Despite these apparent benefits, the collaboration across the architecture, engineering and construction (AEC) disciplines is largely based on the exchange of 2D drawings. This paper reports the findings from a research project that aims at developing measures to enhance BIM-based collaboration in the AEC industry. Based on focus group interviews with industry participants and case studies of BIM applications, visualisation was identified as an interactive platform across the design and non-design disciplines. It is argued that visualisation can enhance the motivation for BIM-based collaboration through integration of advanced visualisation techniques such as virtual reality (VR) and augmented reality (AR). An AR interface for a BIM server is also presented and discussed in the paper. AR can open up potential opportunities for exploring alternatives to data representation, organisation and interaction, supporting seamless collaboration in BIM.

summary	This article presents the contribution of our research to the description of the built elements in the site where information is shared by partners who are distant from one another and focused on fields of expertise that are distinct but concurrent. Our work aims to provide an information system that promotes cooperation between the buildings actors, by sharing a unique data model among the partners involved in the building construction processes. It takes into account the technical data needed in the different phases of the supply chain management cycle in the construction field. To answer a cooperative context, our work is based on the fundamental assumption that it is possible to structure a building description following the economist’s view point. During the implementation phase, the different activities on a building site can be described as a model that integrates all the related tasks and includes all the work practices and requirements shared among the partners of the architectural project.

title	Stage-based design briefing beyond the waterfall model: tracing students’ design processes in relation to prescribed design stages throughout an architectural design studio
doi	https://doi.org/10.52842/conf.caadria.2010.199
source	Proceedings of the 15th International Conference on Computer Aided Architectural Design Research in Asia / Hong Kong 7-10 April 2010, pp. 199-208
summary	Based on visualisations of data obtained from field observations, this paper describes and discusses how a group of ten undergraduate students of architecture negotiated their ways through the tutorials of a design studio lasting 17 weeks. The main question guiding this empirical study is how the initially prescribed linear, stage-based framework of the design studio relates to design processes as experienced by participating students and as observed by myself as tutor and participant observer. Visualisations of tutorial observations show that instead of proceeding from one stage to the next sequentially, students tend to engage in continuous and parallel re-consideration of almost all aspects of their work. This results in a process that can be described as a cumulative and layered process, and illustrated as ‘fan’-shaped diagrams. The role of the design stages initially scheduled in the detailed studio brief seems to be to gradually introduce students to increasingly advanced and challenging project scopes rather than to enforce sequential design steps.

source	FUTURE CITIES [28th eCAADe Conference Proceedings / ISBN 978-0-9541183-9-6] ETH Zurich (Switzerland) 15-18 September 2010, pp.403-410
summary	This paper introduces a JAVA based library for parametric modeling through programming. From the recent advent of scripting tools integrated into commercial CAAD software and everyday design practice, the use of programming applied to an architectural design process becomes a necessary field of study. The ANAR+ library is a parametric geometry environment meant to be used as programming interface by designers. Form exploration strategies based on parametric variations depends on the internal logic description, a key role for form generation. In most commercial CAD software, geometric data structures are often predefined objects, thus constraining the form exploration, whereas digital architectural research and teaching are in need for an encompassing tool able to step beyond new software products limitations. We introduce key concepts of the library and show a use of the library within a form finding process driven by irradiance simulation.

title	Sketch-based Methods for Researching Building Layouts through the Semantic Fingerprint of Architecture
source	Computer Aided Architectural Design Futures 2011 [Proceedings of the 14th International Conference on Computer Aided Architectural Design Futures / ISBN 9782874561429] Liege (Belgium) 4-8 July 2011, pp. 85-102.
summary	The paper focuses on the early stages of the design process where the architect needs assistance in finding reference projects and describes different aspects of a concept for retrieving previous design solutions with similar layout characteristics. Such references are typically used to see how others have solved a similar architectural problem or simply for inspiration. Current electronic search methods use textual information rather than graphical information. The configuration of space and the relations between rooms are hard to represent using keywords, in fact transforming these spatial configurations into verbally expressed typologies tends to result in unclear and often imprecise descriptions of architecture. Nowadays, modern IT-technologies lead to fundamental changes during the process of designing buildings. Digital representations of architecture require suitable approaches to the storage, indexing and management of information as well as adequate retrieval methods. Traditionally planning information is represented in the form of floor plans, elevations, sections and textual descriptions. State of the art digital representations include renderings, computer aided design (CAD) and semantic information like Building Information Modelling (BIM) including 2D and 3D file formats such as Industry Foundation Classes (IFC) (IAI, 2010). In the paper, we examine the development of IT-technologies in the area of case-based reasoning (Richter et al., 2007) to provide a sketch-based submission and retrieval system for publishing and researching building layouts including their manipulation and subsequent use. The user interface focuses on specifying space and their relations by drawing them. This query style supports the spatial thinking approach that architects use, who often have a visual representation in mind without being able to provide an accurate description of the spatial configuration. The semantic fingerprint proposed by (Langenhan, 2008) is a description and query language for creating an index of floor plans to store meta-data about architecture, which can be used as signature for retrieving reference projects. The functional spaces, such as living room or kitchen and the relation among on another, are used to create a fingerprint. Furthermore, we propose a visual sketch-based interface (Weber et al., 2010) based on the Touch&Write paradigm (Liwicki et al., 2010) for the submission and the retrieval phase. During the submission process the architect is sketching the space-boundaries, space relations and functional coherence's. Using state of the art document analysis techniques, the architects are supported offering an automatic detection of room boundaries and their physical relations. During the retrieval the application will interpret the sketches of the architect and find reference projects based on a similarity based search utilizing the semantic fingerprint. By recommending reference projects, architects will be able to reuse collective experience which match the current requirements. The way of performing a search using a sketch as a query is a new way of thinking and working. The retrieval of 3D models based on a sketched shape are already realized in several domains. We already propose a step further, using the semantics of a spatial configuration. Observing the design process of buildings reveals that the initial design phase serves as the foundation for the quality of the later outcome. The sketch-based approach to access valuable information using the semantic fingerprint enables the user to digitally capture knowledge about architecture, to recover and reuse it in common-sense. Furthermore, automatically analysed fingerprints can put forward both commonly used as well as best practice projects. It will be possible to rate architecture according to the fingerprint of a building.

summary	In intelligent epoch, automatic parameter design systems reduce the requirements of the skills needed to create objects. The creator only needs to select the most perceptual primitive form to automatically generate the data system that iterates to the most efficient solution. In this paper, a method of combining performance driven optimization with parametric design is proposed. The iterative evolution is under the control of performance loop and fabrication loop, which makes all the data provided by parametric design in a practical project available for exploring structural analysis and digital prefabrication. Related to the case of surface steel structure, parametric optimization is not limited to a set of shape types or design problems, it would be based on the generality and built-in characteristics of parametric modelling environment in the most convenient and flexible way. (Rolvink et al. 2010)And the given parameters would be fed back on geometric structure, performance indicators, and design variables, so that designers can easily and effectively coordinate and try different solutions. The system transforms the generated data into machine language so that the process including design, analysis, manufacturing, and construction can maintain the orthogonal persistence of the data.

summary	This paper deals with the research of the building shape in a constant and dialectical relationship with thermal performance. The purpose of this research is to understand and explore the dialogue between shape and performance with generative strategies. The method was based on the works by Oxman (2010), Olgyay (2015), and Di Mari & Yoo (2012), by means that relate the form to performance issues. The thermal performance data found to result from the relationship between thermal conditions, the shape of the envelope, and the characteristics of the eight Brazilian bioclimatic zones.

summary	The “Condensed Design Project” aims to discuss and reflect on how the levels of auxiliary intelligence associated with dynamic collaborative systems of data visualization can help research, organize, manage, analyze and compare dense data amounts of historical facts and events. The main objective is to understand how systems endowed with “auxiliary intelligence” help to assimilate and emulate methods and knowledge of different researchers, and at the same time are able to promote cooperation and research, as well as the study and teaching of design history. And finally, it describes the experience of the use of “specialist system” and “reasoning system based on cases” concepts.

title	Supporting 3D city modelling, collaboration and maintenance through an open-source revision control system
doi	https://doi.org/10.52842/conf.caadria.2010.347

summary	The creation of a 3D city model is usually a very time-consuming process and due to the constant development of the city it also has to be updated accordingly. One of the problems with large 3D city models is that they contain a huge amount of data that has to be stored and processed when it is used. The storage and management of the models are therefore a very important issue. The management issue is often that many people are collaborating and working on the 3D city model at the same time and are located at physically different locations. In this paper we present an application for collaboration, maintenance and storing of 3D city models using an open-source subversion controlled system. It is a client server based with a file-based structure on the client side. This system is not as complex as the Oracle database and is not limited to a specific file format. We have integrated the revision control system into our VR application but it is also possible to have external revision control using a default file manager, such as Explorer in Microsoft Windows. The system has been tested in three different virtual reality projects, all applied to urban planning.
