title	Performative Building Skin Systems: A Morphogenomic Approach Towards Developing Real-Time Adaptive Building Skin Systems
source	International Journal of Architectural Computing vol. 7 - no. 4, 643-676
summary	Morphogenomics, a relatively new research area, involves understanding the role played by information regulation in the emergence of diverse natural and artificially generated morphologies. Performative building skin systems as a bottom-up parametric formation of context aware interdependent, ubiquitously communicating components leading to the development of continually performative systems is one of the multi-scalar derivations of the aforementioned Morphogenomic understanding. The agenda of adaptations for these building skins specifically corresponds to three domains of adaptation: structural, behavioral and physiological adaptations resulting in kinetic adaptability, energy generation, conservation, transport and usage principles as well as material property based changes per component. The developed skins adapt in real time via operating upon ubiquitous communication and data-regulation protocols for sensing and processing contextual information. Computational processes and information technology based tools and techniques such as parametric design, real-time simulation using game design software, environmental information mapping, sensing and actuating systems coupled with inbuilt control systems as well as manufacturing physical models in collaboration with praxis form a vital part of these skin systems. These experiments and analysis based on developing intrinsic inter-dependencies between contextual data, structure and material logistics thus lay the foundation for a new era of continually performing, self powering, real-time adaptive intelligent building skin systems.

summary	Process/product complexity is at present an unavoidable component of present building design approach that affects building product’s quality. To overcome this problem, effective collaboration is required among all the actors involved in the design process. Data and information exchange is not sufficient to guarantee mutual understanding; to support effective collaboration among actors; it is required a proper knowledge formalization and management. This paper reports on an innovative structure for knowledge modeling in cross-disciplinary building design, that has been formalized in a general template. The proposed Knowledge Model has been, at present, implemented by means of available ontology editors and is going to be used into teaching courses to check its efficiency in collaborative building design classes.

title	A Digital Design Environment for Large- Scale Rapid Manufacturing

summary	Innovation in architectural design often follows technological innovation. This innovation can often be related to advances in construction techniques or design tools. This paper focuses on the development of a digital design environment for a new manufacturing process that can produce large architectural components. The design environment can be customized so that it incorporates both the flexibility and the constraints of the construction technology, such that the components produced maximize the core concept of the technology. Rapid Prototyping is a mature technology that has been around for 25 years in the manufacturing and product design industries. It is used primarily to speed up the product design cycle time from concept to physical realization for evaluation; it is now gaining a foothold in contemporary architectural practice. A number of protagonists are taking the Rapid Prototyping concept a stage further by developing large-scale processes capable of printing architectural components; there are even claims of the ability to produce whole buildings. These processes will give the architect a new palette of choice in terms of component design, and promise similar levels of geometric freedom as the Rapid Prototyping counterparts.

summary	This research explores new ways to integrate manufacturing knowledge in to design phases. Through the use of design for manufacturing (DfM) concept, and looking at relations between its potential application in component design and its implementation using digital manufacturing technologies, the author implemented a DfM model that varies from previous models by incorporated learning in the process. This process was based on; a knowledge systematization process; and the incremental development and refinement of design heuristics and metrics. Subsequently the attempt on this research is twofold. One is to realize a process to capture and organize manufacturing knowledge, and second to organize that knowledge and make it available as a DfM model for component design using specific CNC technology.

title	Parametric Modelling of Architectural Surfaces
source	Proceedings of the 14th International Conference on Computer Aided Architectural Design Research in Asia / Yunlin (Taiwan) 22-25 April 2009, pp. 635-644
doi	https://doi.org/10.52842/conf.caadria.2009.635
summary	Parametric modelling is gaining in popularity as both a fabrication and design tool, but its application in the architectural design industry has not been widely explored. Parametric modelling has the ability to generate complex forms with intuitively reactive components, allowing designers to express and fabricate structures previously too laborious and geometrically complex to realise. This allows designers to address a project at both the macro and micro levels of resolution in the governing control surface and the individual repetitive component. This two level modelling control, of component and overall surface, can allow designers to explore new types of form generation subject to parametric constraints. Shading screens have been selected as the focus for this paper and are used as a medium to explore form generation within a given set of functional parameters. Screens can have many applications in a building but for the purpose of the following case studies, lighting quality and passive sun control are the main functional requirement. A set of screen components have been designed within certain shading parameters to create a generic component that can automatically adapt to any given climatic conditions. These will then be applied to surfaces of varying degrees of geometric complexity to be analysed in their ability to correctly tessellate and create a unified screening array true to the lighting requirements placed on the generic component.

title	Parametric Constructionist Kits: Physical Design and Delivery System for Rapid Prototyping Devices
source	International Journal of Architectural Computing vol. 7 - no. 4, 623-642
summary	In this paper we illustrate a design methodology based on constructionist learning principles with CAD modeling and rapid prototyping. The belief is that a constructionist approach to design development extends design possibilities beyond the visual aspects of rendering and animation to building construction by way of component-based parametric modeling. This is demonstrated by way of construction kits as a proposed system of physical design production, individually and in groups. Results of the system are data sets for model manufacturing, hand assembly and design feedback. The impact of this work is to teach physical modeling as a system of production that will allow a designer hands-on learning of building structure, material mechanics and building component behavior. Also design success is newly defined as a relationship between the visual and physical evaluation; not just the visual. The paper ends with examples of complex design models generated from elements in the construction kit and a physical design grammar used to guide element assembly. Although the examples in this paper satisfy model making for building structures we believe this system can be useful for anyone who needs to construct physical artifacts beyond traditional scales found in rapid prototyping.

title	Digital Templates: Diagrams of Associations

doi	https://doi.org/10.52842/conf.acadia.2009.167
summary	This paper claims that a speculative design space exists within the crafting of digital rule-based associations in parametric modeling environments, which promises to support potent contemporary designs in architecture. In addition to reviewing some diagrammatic frameworks located within the techniques of associative design modeling, this paper also details a project for a research-oriented practice based on the development of a registry of digital diagrams called “re-usables.” Working with “re-usable templates” of association, a precise sequence of design logic is invented for each project, while some of its aspects are re-used and re-configured. Such practice aims to operate between the “one-off” world of the all-custom and the entirely reproducible world of “copy-paste.”

title	A Study of The Virtual Reality Simulation System for LRT Projects Towards Sustainable City
source	Proceedings of the 14th International Conference on Computer Aided Architectural Design Research in Asia / Yunlin (Taiwan) 22-25 April 2009, pp. 23-32

summary	Recently, many cities in Japan and in other developed nations face problems such as decadence of downtown areas, aged society with a fewer number of children, dependence on automobile transport, etc. And redesign of public transportation services (e.g. tram) is thought to be one of the solutions for these problems. The introduction of LRT is investigated in various places, however, when a public traffic system like LRT is introduced, it is necessary to consider not only the transportation oriented aspects, but also landscapes and plans for a future sustainable city. Therefore, city planners are required to promote workshop-type in the design process to deal with citizens, companies, NPOs, etc. In this research, both components of the VR system for LRT projects and the system that enables the examination from various aspects of traffic, landscapes, city planning, etc., were studied.

title	Services in Digital Design: new visions for AEC-field collaboration
source	International Journal of Architectural Computing vol. 7 - no. 3, 459-478
summary	The objective of this paper is to describe contemporary digital building design from a service provider aspect. The constrained framework of this work is digital architectural design practice. When design is seen in the context of the AEC field, a process oriented approach is commonly used in describing collaboration and evolutionary progress of the design work as a project. Design projects are scheduled chains of activities which result in design delivery or actual physical buildings as the end products of the project. Recently developments in building information modelling (BIM) have presented fundamentally new ways for collecting, exploring, and sharing design information. This study develops the novel digital approach: BIM as design services. The key finding of the study is that parts of the design domain can be described as services in the changing digital environment. The scientific contribution of this paper is in describing contemporary digital design practice with an alternative service approach. A framework for such services is also presented. This work will expand the authors' contribution to research on preliminary architectural design using building information models.

source	Proceedings of the 15th International Conference on Computer Aided Architectural Design Research in Asia / Hong Kong 7-10 April 2010, pp. 457-466
doi	https://doi.org/10.52842/conf.caadria.2010.457
summary	The research presented in this paper investigates ways of providing better design applications for technologies in the field of Urban Digital Media (UDM). The work takes an emergent approach, evolving a design strategy through the early engagement of stakeholders. The paper discusses research in a design-led creative intersection between media technology, culture and the arts in the built environment. The case study discusses opportunities for the enhancement of a university campus experience, learning culture and community, through the provision of an integrated digital presence within campus architecture and urban spaces. It considers types of information architecture (Manovich, 2001) and designs for use in urban settings to create communication-rich, advanced and interactive designed spaces (Haeusler, 2009). The presented research investigates how to create a strategy for display technologies and networked communications to transform and augment the constructed reality of the built environment, allowing new formats of media activity.

summary	Within computational environmental design (CED), different Machine Learning (ML) models are gaining ground. They aim for time efficiency by automating simulation and speeding up environmental performance feedback. This study suggests an approach that enhances not the optimization but the generative aspect of environmentally driven ML processes in architectural design. We follow Stan Allen's (2009) idea of 'field conditions' as a bottom-up phenomenon according to which form and space emerge from local invisible and dynamic connections. By employing parametric modeling, environmental analysis data, and conditional Generative Adversarial Networks [cGAN] we introduce a generative approach in design that reverses the typical design process of going from formal interpretation to analysis and encourages the emergence of spatial configurations with embedded environmental intelligence. We call it Intensive-driven Environmental Design Computation [IEDC], and we employ it in a case study on a residential building typology encountered in the Mediterranean. The paper describes the process, emphasizing dataset preparation as the stage where the logic of field conditions is established. The proposed research differentiates from cGAN models that offer automatic environmental performance predictions to one that spatial predictions stem from dynamic fields.

doi	https://doi.org/10.52842/conf.caadria.2009.013
summary	This paper examines a different design approach called integrated. The term “integrated” has a dual utilization in this study. The first use refers to the integration of form and building performance. The second use refers to the integration of interrelated and diverse building performances involving multiple disciplines. The integrated design approach analyzes and evaluates several interrelated design systems involving different disciplines in the early design phase. The goal of the approach is the generation of design alternatives guided simultaneously by two basic objectives: the aspiration for form exploration and the satisfaction of the performances of interrelated systems.

title	Creation of an Evolutive Conceptual Know-how Framework for Integrative Building 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. 435-450.
summary	Low productivity of the building sector today is attributed to the fragmentation of tasks, disciplines and responsibilities, as well as to the resistance to adopt integrative work processes and digital means. The increased complexity of architectural projects and the aroused social consciousness for sustainable environment calls for integrative design collaboration. Thus, there is need for a Conceptual Framework combining work processes, technological means and policy aspects. According to the literature, integrative multidisciplinary design is a strategy resulting in high performance buildings nurturing sustainable way of living (Reed et al. 2009, Krygiel & Nies 2008). Responding to the increased technological complexity of our built environment, as well as to the objective of meeting multiple criteria of quality, both necessitating multidisciplinary collaboration during design, Building Information Modeling (BIM) is seen as a powerful means for fostering quality, augmenting productivity and decreasing loss in construction. Based on recent research, we can propose that a sustainable building can be designed through an integrative design process (IDP) which is best supported by BIM. However, our ongoing research program and consultations with advanced practitioners underscore a number of limitations. For example, a large portion of the interviewed professionals and construction stakeholders do not necessarily see a link between sustainable building, integrative design process and BIM, while in our opinion, their joint use augments the power of each of these approaches taken separately. Thus, there is an urgent necessity for the definition of an IDP-BIM framework, which could guide the building industry to sustainable results and better productivity. This paper defines such a framework, whose theoretical background lays on studies in social learning (activity theory and situated action theories). These theories suggest that learning and knowledge generation occurs mainly within a social process defined as an activity. This corresponds to the context in which the IDP-BIM framework will be used, its final objective being the transformation of building design practices. The proposed IDP-BIM framework is based on previous research and developments. Thus, firstly, IDP process was well formalized in the Roadmap for the Integrated Design Process‚ (Reed et al.) which is widely used as a guideline for collaborative integrative design by innovating practices in USA and Canada. Secondly, the National Building Information Modeling Standard (NBIMS) of the USA is putting an enormous effort in creating a BIM standard, Succar (2008) recently proposed a conceptual framework for BIM, but BIM ontology is still under development (Gursel et al 2009). Thirdly, an iterative design process bound to gating reviews (inspired from software development processes) was found to be successful in the context of multidisciplinary design studios (reported in our previous papers). The feedback from this study allowed for modifications and adjustments included in the present proposal. The gating process assures the good quality of the project and its compliance to the client's requirements. The challenge of this research is to map the above mentioned approaches, processes and technologies into the design process, thus creating an integrated framework supporting and nurturing sustainable design. The IDP-BIM framework can be represented by a multidimensional matrix linked to a semantic network knowledge database: - the axes of the matrix being the project timeline, the design process actors and building stakeholders (architect, engineers, client, contractor, environmental biologist, etc.), or different aspects of building performance (environmental, functional, social, interior environment quality, cost, etc.); and - the knowledge database providing multiple layers of semantic support in terms of process, domain knowledge, technology and workflow at a given moment of the project and for a given actor or building aspect. The IDP-BIM framework is created as an evolutive digital environment for know-how and will have an established protocol for regular updates. The paper will firstly present the state of the art in IDP and BIM. Secondly, it will expose the methodology used for the definition of the Framework, followed by a description of its structure, contents and digital implementation. Then, some scenarios for the use of the Framework will be shown as validation.

summary	For many, integration within the building industry is seen as a likely outcome as architecture, engineering, and construction fully engage the digital technologies in the design, analysis, and production of buildings. Concepts such as integrated design, integrated practice and integrated project delivery (IPD) have gained prominence in architecture over the past several years as relatively new paradigms.What is usually meant by these terms is a multidisciplinary, collaborative approach to design in which various participants from the building industry – architects, engineers, contractors, fabricators, etc. – participate jointly from the earliest stages of design, fluidly crossing the conventional disciplinary and professional boundaries to deliver an innovative product at the end.

title	How much is it? About the use of the element method in conjunction with optimization techniques

summary	It is obvious that the preparation and compliance with cost estimates for a proposed architectural design is indispensable for successful realization of building projects. A variety of methods exists that can be used by the architect to achieve this objective. However, most of these methods are regularly not used until the design is completed. In many cases this procedure leads to cost overruns. Hence, our paradigm is to estimate the total building costs prior to the generation of detailed designs and thus use the costs of building elements as design parameters right from the beginning to produce design solutions which entail the least possible costs. For this purpose we invert the customary process through the use of building element costs as a means for the automatic generation of monetarily assessable design solutions. For various reasons we concentrate on the design of housing projects. The methodology however, can be adopted to any other kind of building typology.

summary	Using several NBBJ civic projects as case studies, this paper provides an overview of how NBBJ’s Los Angeles design studio is leveraging parametric and generative processes for the design of projects such as stadiums and exposition halls. A combination of ambitious intent and fast project schedules necessitates the use of advanced parametric tools to quickly solve complex problems, generate unique features, and automate parts of the design process. Designers will utilize digital tools for a variety of purposes, which can be classified under two general categories. The first and most common application of the technology is within the category of rationalization and optimization. The tool, in this case, is limited to the role of a production device that aids the designer in efficiently solving complex design problems. In more unique projects, the advanced technology acts as a generative tool and is an integral part of a working design methodology. In this case, the design technology becomes more than just a tool at the designer’s disposal. Rather, it has the potential to act as a critical lens for identifying new possibilities in the architecture.

summary	Mesh segmentation has become an important and well-researched topic in computational geometry in recent years (Agathos et al. 2008). As a result, a number of new approaches have been developed that have led to innovations in a diverse set of problems in computer graphics (CG) (Sharmir 2008). Specifically, a range of effective methods for the division of a mesh have recently been proposed, including by K-means (Shlafman et al. 2002), graph cuts (Golovinskiy and Funkhouser 2008; Katz and Tal 2003), hierarchical clustering (Garland et al. 2001; Gelfand and Guibas 2004; Golovinskiy and Funkhouser 2008), primitive fitting (Athene et al. 2004), random walks (Lai et al.), core extraction (Katz et al.) tubular multi-scale analysis (Mortara et al. 2004), spectral clustering (Liu and Zhang 2004), and critical point analysis (Lin et al. 20070, all of which depend upon a weighted graph representation, typically the dual of a given mesh (Sharmir 2008). While these approaches have been proven effective within the narrowly defined domains of application for which they have been developed (Chen 2009), they have not been brought to bear on wider classes of problems in fields outside of CG, specifically on problems relevant to generative architectural design. Given the widespread use of meshes and the utility of segmentation in GAD, by surveying the relevant and recently matured approaches to mesh segmentation in CG that share a common representation of the mesh dual, this paper identifies and takes steps to address a heretofore unrealized transfer of technology that would resolve a missed opportunity for both subject areas. Meshes are often employed by architectural designers for purposes that are distinct from and present a unique set of requirements in relation to similar applications that have enjoyed more focused study in computer science. This paper presents a survey of similar applications, including thin-sheet fabrication (Mitani and Suzuki 2004), rendering optimization (Garland et al. 2001), 3D mesh compression (Taubin et al. 1998), morphin (Shapira et al. 2008) and mesh simplification (Kalvin and Taylor 1996), and distinguish the requirements of these applications from those presented by GAD, including non-refinement in advance of the constraining of mesh geometry to planar-quad faces, and the ability to address a diversity of mesh features that may or may not be preserved. Following this survey of existing approaches and unmet needs, the authors assert that if a generalized framework for working with graph representations of meshes is developed, allowing for the interactive adjustment of edge weights, then the recent developments in mesh segmentation may be better brought to bear on GAD problems. This paper presents work toward the development of just such a framework, implemented as a plug-in for the visual programming environment Grasshopper.

summary	The design of laboratory buildings entails the implementation of a variety of design constraints such as building codes; design guidelines and technical requirements. The application of these requires from designers the derivation of data not explicitly available at early stages of design, at the same time there is no precise methodology to control the consistency, and accuracy of their application. Many of these constraints deal with providing secure environmental conditions for the activities inside laboratories and their repercussions both for the building occupants and population in general, these constraints mandate a strict control over the building‚Äôs Mechanical Equipment (MEP), in particular the Heating Ventilating and Air Conditioning (HVAC) system. Due to the importance of these laboratory designers are expected to assess their designs not only according spatial relationships, but also design variables such as HVAC efficiency, air pressure hierarchies, operational costs, and the possible implications of their design decisions in the biological safety of the facility. At this point in time, there are no practical methods for making these assessments, without having constant interaction with HVAC specialists. The assessment of laboratory design variables, particularly those technical in nature, such as dimensioning of ducts or energy consumption are usually performed at late stages of design. They are performed by domain experts using data manually extracted from design information, with the addition of domain specific knowledge, the evaluation is done mostly through manual calculations or building simulations. In traditional practices most expert evaluations are performed once the architectural design have been completed, the turn around of the evaluation might take hours or days depending on the methods used by the engineer, therefore reducing the possibility for design alternatives evaluation. The results of these evaluations will give clues about sizing of the HVAC equipment, and might generate the need for design reformulations, causing higher development costs and time delays. Several efforts in the development of computational tools for automated design evaluation such as wheel chair accessibility (Han, Law, Latombe, Kunz, 2002) security and circulation (Eastman, 2009), and construction codes (ww.Corenet.gov.sg) have demonstrated the capabilities of rule or parameter based building assessment; several computer applications capable of supporting HVAC engineers in system designing for late concept or design development exist, but little has been done to assess the capabilities of computer applications to support laboratory design during architectural Preliminary Concept Design(PCD) (Trcka, Hensen, 2010). Developments in CAD technologies such as Building Information Modeling (BIM) have opened doors to formal explorations in generative design using rule based or parametric modeling [7]. BIM represents buildings as a collection of objects with their own geometry, attributes, and relations. BIM also allows for the definition of objects parametrically including their relation to other model objects. BIM has enabled the development of automated rule based building evaluation (Eastman, 2009). Most of contemporary BIM applications contemplate in their default user interfaces access to design constraints and object attribute manipulations. Some even allow for the application of rules over these. Such capabilities make BIM viable platforms for automation of design data derivation and for the implementation of generative based design assessment. In this paper we analyze the possibilities provided by contemporary BIM for implementing generative based design assessment in laboratory buildings. In this schema, domain specific knowledge is embedded in to the BIM system as to make explicit design metrics that can help designers and engineers to assess the performance of design alternatives. The implementation of generative design assessments during PCD can help designers and engineers to identify design issues early in the process, reducing the number of revisions and reconfigurations in later stages of design. And generally improving design performance.

title	A Multi-dimensional Exploration of Urban Attributes by Data Mining
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. 333-350.
summary	The paper which is proposed here will introduce an ongoing research project aiming to research data mining as a methodology of knowledge discovery in urban feature analysis. To address the increasing multi-dimensional and relational complexity of urban environments requires a multidisciplinary approach to urban analysis. This research is an attempt to establish a link between knowledge discovery methodologies and automated urban feature analysis. Therefore, in the scope of this research we apply data mining methodologies for urban analysis. Data mining is defined as to extract important patterns and trends from raw data (Witten and Frank, 2005). When applied to discover relationships between urban attributes, data mining can constitute a methodology for the analysis of multi-dimensional relational complexity of urban environments (Gil, Montenegro, Beirao and Duarte, 2009) The theoretical motivation of the research is derived by the lack of explanatory urban knowledge which is an issue since 1970‚Äôs in the area of urban research. This situation is mostly associated with deductive methods of analysis. The analysis of urban system from the perspective of few interrelated factors, without considering the multi-dimensionality of the system in a deductive fashion was not been explanatory enough. (Jacobs, 1961, Lefebvre, 1970 Harvey, 1973) To address the multi-dimensional and relational complexity of urban environments requires the consideration of diverse spatial, social, economic, cultural, morphological, environmental, political etc. features of urban entities. The main claim is that, in urban analysis, there is a need to advance from traditional one dimensional (Marshall, 2004) description and classification of urban forms (e.g. Land-use maps, Density maps) to the consideration of the simultaneous multi-dimensionality of urban systems. For this purpose, this research proposes a methodology consisting of the application of data mining as a knowledge discovery method into a GIS based conceptual urban database built out of official real data of Beyoglu. Generally, the proposed methodology is a framework for representing and analyzing urban entities represented as objects with properties (attributes). It concerns the formulation of an urban entity‚Äôs database based on both available and non-available (constructed from available data) data, and then data mining of spatial and non-spatial attributes of the urban entities. Location or position is the primary reference basis for the data that is describing urban entities. Urban entities are; building floors, buildings, building blocks, streets, geographically defined districts and neighborhoods etc. Urban attributes are district properties of locations (such as land-use, land value, slope, view and so forth) that change from one location to another. Every basic urban entity is unique in terms of its attributes. All the available qualitative and quantitative attributes that is relavant (in the mind of the analyst) and appropriate for encoding, can be coded inside the computer representation of the basic urban entity. Our methodology is applied by using the real and official, the most complex, complete and up-to-dataset of Beyoglu (a historical neighborhood of Istanbul) that is provided by the Istanbul Metropolitan Municipality (IBB). Basically, in our research, data mining in the context of urban data is introduced as a computer based, data-driven, context-specific approach for supporting analysis of urban systems without relying on any existing theories. Data mining in the context of urban data; ‚Ä¢ Can help in the design process by providing site-specific insight through deeper understanding of urban data. ‚Ä¢ Can produce results that can assist architects and urban planners at design, policy and strategy levels. ‚Ä¢ Can constitute a robust scientific base for rule definition in urban simulation applications such as urban growth prediction systems, land-use simulation models etc. In the paper, firstly we will present the framework of our research with an emphasis on its theoretical background. Afterwards we will introduce our methodology in detail and finally we will present some of important results of data mining analysis processed in Rapid Miner open-source software. Specifically, our research define a general framework for knowledge discovery in urban feature analysis and enable the usage of GIS and data mining as complementary applications in urban feature analysis.
