title	Constructive interpretation with examples from interpretation of floor plans
doi	https://doi.org/10.52842/conf.caadria.2011.633
source	Proceedings of the 16th International Conference on Computer Aided Architectural Design Research in Asia / The University of Newcastle, Australia 27-29 April 2011, pp. 633-642
summary	This paper describes the role that interpretation plays in facilitating situated design and presents an implementation that shows a system interpreting floor plans. Designers often see more in what they produce than they intentionally put there. Cognitive studies suggest that this helps develop design ideas. Interpretation is described as the use of expectations to construct an internal representation of an external representation (such as a sketch). An implementation is described. As an example of its capability the system, primed on floor plans, looks at a randomly generated image and can find a floor plan within it. The system produces different results with the same image if it has different expectations. This is used to discuss the notions of a space of possible designs and the two way relationship between expectations informing interpretation and interpretation changing the expectations (design ideas) of a designer. Further work is suggested and the ideas are discussed.

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.

title	Topology pattern mining: A visual approach for representing and retrieving design patterns of spatial topology in a case library
doi	https://doi.org/10.52842/conf.caadria.2011.535
source	Proceedings of the 16th International Conference on Computer Aided Architectural Design Research in Asia / The University of Newcastle, Australia 27-29 April 2011, pp. 535-544
summary	This paper aims to apply the clustering analysis algorithm to analyze and classify the pattern of spatial topology of floor plans within a case library named “Open Case Study (OCS)”. Based on the results of classifications, this paper proposes a visual interface named “Topology Pattern Mining (TPM)” to present and rank searching results in response to user’s queries. The purpose of TPM is to extend the capacity of OCS for representing implicit knowledge of spatial topology. TPM can retrieve and classify design patterns of spatial topology, and thereby helps users to learn the design knowledge within relevant cases.

title	Motivation, cyberworlds and collective design
doi	https://doi.org/10.52842/conf.caadria.2011.697
source	Proceedings of the 16th International Conference on Computer Aided Architectural Design Research in Asia / The University of Newcastle, Australia 27-29 April 2011, pp. 697-706
summary	Collaborative design is characterised by small-scale, carefully structured, professional design teams. The increasing popularity of social computing and mass communication supported by cyberworlds suggests there is now also a strong possibility of design through mass participation, beyond small-scale, collaborative design scenarios. However to achieve collective intelligence in design, there is a need to motivate large groups of users to contribute constructively to design tasks. This paper studies different types of cyberworlds to classify the motivation profiles of their user bases. We compare these motivation profiles to those required for the emergence of collective intelligence and develop a list of technological requirements for cyberworlds to support collective intelligence and design.

title	Interpreting Digital Heritage: A Conceptual Model with End-Users' Perspective
source	International Journal of Architectural Computing vol. 9 - no. 1, 99-114
summary	Present virtual heritage projects are mostly focused either on ‘process’ or ‘product’ but rarely consider ‘users’ (end-users' perception of the content) with project contents predominantly developed with an ‘ocular-centric’ tendency. There is no significant interpretation method or principle for interpreting digital heritage like other disciplines such as archaeology. This paper argues that, for better interpretation and experience of a digital heritage site, a comprehensive interpretation method is required, which should address end-users with various background, overcome the linearity in narrative level and subjectiveness in content creation. This paper also argues that instead of predetermined instructional sequences or descriptive interpretation, the interaction setting can be participatory and contributive, where the end-users and environment may engage in ‘dialogic-interaction’. In terms of methodology, ‘Interpretation’ is first conceptualized by assimilating definitions from various heritage scholars and interpretation organizations. Notions of interpretation-practice and level of interaction are identified from reviewing some online digital heritage projects. By identifying weaknesses, this paper finally proposes a conceptual model for developing a comprehensive interpretation method for future digital heritage projects.

title	Top-down Approach for Interaction of Knowledge-Based Parametric Objects and Preliminary Massing Studies for Decision Making in Early Design Stages
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. 149-164.
summary	Design activities vary from high-degree of freedom in early concept design stages to highly constrained solution spaces in late ones. Such late developments entail large amount of expertise from technical domains. Multiple parallel models handle different aspects of a project, from geometric master models to specific building components. This variety of models must keep consistency with the design intent while they are dealing with specific domains of knowledge such as architectural design, structure, HVAC, MEP, or plumbing systems. Most of the expertise embedded within the above domains can be translated into parametric objects by capturing design and engineering knowledge through parameters, constraints, or conditionals. The aim of this research is capturing such expertise into knowledge-based parametric objects (KPO) for re-usability along the design process. The proposed case study ‚Äì provided by SOM New York‚ is the interaction between a massing study of a high-rise and its building service core, which at the same time handles elevators, restrooms, emergency stairs, and space for technical systems. This project is focused on capturing design expertise, involved in the definition of a building service core, from a high-rise senior designer, and re-using this object for interaction in real-time with a preliminary massing study model of a building, which will drive the adaption process of the service core. This interaction attempts to provide an integrated design environment for feedback from technical domains to early design stages for decision-making, and generate a well-defined first building draft. The challenges addressed to drive the instantiation of the service core according to the shifting characteristics of the high-rise are automatic instantiation and adaptation of objects based on decision rules, and updating in real-time shared parameters and information derived from the high-rise massing study. The interaction between both models facilitates the process from the designer‚Äôs perspective of reusing previous design solutions in new projects. The massing study model is the component that handles information from the perspective of the outer shape design intent. Variations at this massing study model level drive the behavior of the service core model, which must adapt its configuration to the shifting geometry of the building during design exploration in early concept design stages. These variations depend on a list of inputs derived from multiple sources such as variable lot sizes, building type, variable square footage of the building, considerations about modularity, number of stories, floor-to-floor height, total building height, or total building square footage. The shifting combination of this set of parameters determines the final aspect of the building and, consequently, the final configuration of the service core. The service core is the second component involved in the automatic generation of a building draft. In the context of BIM, it is an assembly of objects, which contains other objects representing elevators, restrooms, emergency stairs, and space for several technical systems. This assembly is driven by different layouts depending on the building type, a drop-off sequence, which is the process of continuous reduction of elevators along the building, and how this reduction affects the re-arrangement of the service core layout. Results from this research involves a methodology for capturing design knowledge, a methodology for defining the architecture of smart parametric objects, and a method for real-time-feedback for decision making in early design stages. The project also wants to demonstrate the feasibility of continuous growth on top of existing parametric objects allowing the creation of libraries of smart re-usable objects for automation in design.

summary	Today, right along with the products marketed and manufactured by the mass production techniques, continuously developing computing and technology have an undeniable impact on customized design, in which the users have a say on the products design and manufacturing. Mass customization is slowly settling down in architectural design concepts as well, like housing which is one of the best areas where users can reflect their living habits and preferences. In this study, user centric mass customization based model is developed, which creates housing floor plan combining the user-supplied data with the best possible creations generated by the genetic algorithms.

title	Analyzing the Ventilation Performance of Tropical High Density Residential Precincts using Computational Fluid Dynamics
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. 351-366.
summary	Major cities in the world are getting bigger as they continue to grow to cater for more population increase. These cities normally forced the urban planning to go high density. In the tropical context, high density cities like Singapore and Hong Kong do not have the luxury of space to go low rise and compact. These cities have to build to the floor area ratio of 4 and above to cater for the population. Their only solution is to go up, as high as possible, to the extent that the natural wind flow pattern will be altered, which brings environmental impact to the people. This is generally not good since wind flow helps to maintain the thermal comfort of the people as heat and pollutants are being channeled out of the city to avoid Urban Heat Island effect. In the tropical context, wind flow is crucial to maintain people‚Äôs comfort as the temperature is generally very high from the exposure of the sun for the entire year. Studies have shown that wind flow plays the most significant part in maintaining human comfort despite exposing to direct sunlight in the tropics. Therefore, wind flow analysis is extremely crucial to make the design sustainable and energy efficient, as people will not have to depend on mechanical ventilation to compensate for the lack of wind flow. Computational Fluid Dynamics (CFD) has always been used in the field of architecture, urban design and urban planning to understand the patterns of wind flow through the built environment apart from wind tunnel tests. The availability of more powerful hardware for the mainstream computer users as well as the lowering costs of these computers made CFD more possible to be adopted in the design world today. This also means using CFD in the design process, especially to analyze the impact of the design to the current site conditions and annual wind patterns will help the new design to be more responsive to the site. The interest of this paper is to analyze the high density typologies to see how well they respond to the local wind flow pattern. A typology is considered acceptable when the wind flow going through the site is still maintaining acceptable wind speed. This means it does not block off the wind and create stagnant spaces. Different designs generate different typologies which will respond differently to the wind pattern. The study aims at comparing the local high density typologies in terms of their response to the wind. Changes to a typology can be explored too to see if the performance will be different. For a typology which is considered a total failure in terms of response to wind, it may improve its performance if the orientation is altered. The CFD software can also parametrically respond to the changes of the typologies‚Äô dimensions. This is helpful to see how much more a typology can still be performing well before failure by increasing the floor area index. The easiest way to do this is to pump up the building height. In conclusion, designing in response to wind is extremely important as it is more sustainable and responsive to Urban Heat Island effect. A design which responds well to the wind patterns will help save cost of cooling load and fan expenditure. The people will also be more willing to use the outdoor spaces which will as a whole generate more vibrant city spaces. As a result, a high density city with huge population count can still enjoy good thermal comfort if the general urban planning and design respond well to wind.

summary	The miniature replicas of multi-billion dollar property development projects provide every year a spectacle of the vast imagination of architects and master developers at Cityscape Dubai exhibition. The technical aspect of the model-making industry component is a complex one in that it often engages the modelling of very subtle structures such as twisted towers. One illustration of these is the Infinity Tower in Dubai Marina (designed by SOM). To be completed in 2011, this 330-metre high-rise is composed of 80 floors and is intended to be the world’s tallest high-rise featuring a 90_ twist. Each floor rotates by 1.2 degrees to attain the full 90_ spiral, creating the shape of a helix. The paper discusses the physical modelling of this tower, with a description of both the digital and the constructive parts.

title	The sensitive tower: Architectural and urban design education faced with fragile metropolitan ecologies

summary	Neighborhoods that are still outside the market target can find alternative ways of re-development. Therefore, it is necessary to design architectures compatible with their fragile ecologies. This research benefits from a previous study where we tried to observe the evolution of the uses of buildings and ways of living faced with changes in environmental conditions in a given urban context. Increased automobile traffic has led to changes in the use of residential spaces whose function was gradually replaced by commercial activities. Making use of graphic-oriented interpretation of urban ambiance and landscape analysis methodology applied to the design of different floor levels, this paper aims to introduce the concept of sensitive tower defined on the basis of observations made in our post-occupancy survey as a teaching strategy for the design studio faced with the current challenges of the contemporary metropolis.

title	Bridging the Gap in Constraint-Based Design
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. 133-148.
summary	Mass customization is one of the most promising computational developments in the AEC industry. Despite recent advances in the production of research-based knowledge, the professional practices lack of a consistent and permanent technology adoption scheme and remain as a very resilient and fragmented industry. This work is a part of an ongoing research project developing guidelines for improving both physical and virtual modeling processes within an architectural design context. Here, we present a customizable model of a space layout explorer. The implementation of the user-driven solution-finding process is based on constraint technology embedded in Autodesk’s Revit® 2011 macros tools, commonly used in the professional practice. The aim of this work is to demonstrate a practical use of a small constraint-based system on software of widespread use. Even though there is still a lack of building information, the model has already several applications in the definition a floor plan layout and in the comparison of several instances of the design solution in the 3D user view. User-driven modifications are not made directly through the 3D model, but through different explicit text tags that describe each parameter on 2D views -although a real time 3D visualization of the model is also available-. The main findings are discussed as guidelines for further research on the end-user involvement on a ‘creative mass customization’ scheme. Also, the implementation of visual aids such as text tags during the customization process can bridge some technical obstacles for the development of interfaces for constraint-based mass customization systems. Before the final discussion, some limitations on the use of this model are described.

title	Optimizing the “characteristic structure”: Combining shape grammars and genetic algorithms to generate urban patterns
doi	https://doi.org/10.52842/conf.ecaade.2011.491
source	RESPECTING FRAGILE PLACES [29th eCAADe Conference Proceedings / ISBN 978-9-4912070-1-3], University of Ljubljana, Faculty of Architecture (Slovenia) 21-24 September 2011, pp.491-500
summary	The present paper is part of an undergoing research that aims at developing software that can generate urban plans, based on contemporary urban design concepts, in an optimized way. As a design method, the project proposes the use of the trilogy formulation/ generation/evaluation, which starts with an outline of the design requirements, proceeds with the definition of generative procedures that can result in these requirements, and follows with the evaluation of the generated designs. The paper describes the development of a computer program that implements some of Marshall’s evaluation methods, and further elaborates them to define generative criteria and to optimize the resulting designs with GA techniques. The program aims at generating what Marshall calls a “characteristic structure”, a type of urban fabric that is usually found in vernacular urban fabrics.

summary	The creation of virtual models of Plans-Reliefs (sometimes called relief maps) is a project to preserve and to make known masterpieces of European Cultural Heritage. In this paper, we present the first experiments carried out in the automatic reconstruction of the fortifications modelled in every plan-relief. Their scale, size and state mean that digitising data alone is not usable. The study of historical documents like the many treatises of fortification allows us to fill in the gap by retrieving all the modelling information required in the creation of a library of parametric components with canonical values. These components are then adjusted according to theoretical ranges with a first set of reference documents like the plans that have been used by the original model makers.

title	Data flow and processing in the computational fractal analysis method

summary	One of the few quantitative methods available for the consistent analysis of architectural form is the ‘box-counting’ approach to determining the approximate fractal dimension of a plan or elevation. In its computational form this method has been used to analyze the plans and facades of a wide range of buildings. The data points produced are synthesized by the software into a series of fractal dimension (D) values that are in turn compiled in various ways to produce a series of composite results describing a complete building. Once this process is complete the data may be coded with additional information producing a set of mathematical results that describe the form of a building. This paper offers the first complete description of this important analytical process from the point of view of information flow, algorithmic operations, review options and data magnitude. No previous paper has detailed the full scope of the data used in the computational method, or the way in which various stages produce different types of outcomes. The purpose of this paper is to elucidate the way in which this particular computational method, drawing its inspiration from the complexity in natural systems, may be used to process different types of information and produce various forms of quantitative data to support architectural design and analysis.
