summary In this work, Type is suggested as a source of knowledge, once acknowledged that it is an efficient response to a specific problem, and that a knowledge based on observation of a greater quantity of occurrence of the phenomenon is more solid. The type is understood under the new Theory of Systems, that is, it carries within itself information on its environment. Thus, its understanding envolves that of the system. A study on the type Traditional Beach Villages of Ceará is then undertaken, using GIS software to retrieve information that are then translated and simulated on a Rhino/Grasshopper scripting.

title Two conceptual design tools and an immersive experience: Beyond the pragmatic-pleasurable split in UX
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. 291-300
summary In a recent study, we compared two conceptual design tools supporting collaboration, a whiteboard software accessed through Internet, and a hybrid immersive system, the Hybrid Ideation Space (HIS). The result of the study appeared to favour the HIS because of its immersive qualities. In this paper, we seek possible explanations as to why immersion delivered a better experience, by looking at the mental workload in relationship to the experience. For the workload we rely on Wickens’ four-dimensional multiple resource model, specifically processing codes (verbal/spatial) and visual channels; and for the experience, Csikszentmihalyi’s concept of flow and our own concept of Design Flow. The designers seemed to be responding to different styles of information processing required of them by each tool, one being more experiential and the other requiring a heavier mental workload. Insight in the cognitive underpinning of a strictly pragmatic immersive experience suggests that UX has also to do with how the information is received and processed by users, without isolating the functional from the rest of the experience.

title Topology pattern mining: A visual approach for representing and retrieving design patterns of spatial topology in a case library
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 A Study on BIM based Energy Efficient Design Improvement for Rural Standard Drawing and Specification in South Korea: Focusing on Using Buffer-Zone
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.430-438
summary Throughout the world, global warming has been considered a severe problem, which has led to efforts being made for technical development to reduce greenhouse gases in the building sector. As more attention has been paid to energy consumption by residential housing in the building sector, policies and studies on domestic dwellings tend to focus on quality improvement and energy-efficient housing development rather than quantitative housing supply. Yet, policies and guidelines considering residential energy efficiency are inclined to focus on performance and lack in integrated consideration in connection with design. Hence, it seems necessary to compare and analyze design and energy efficiency and to study correlations between housing design and energy. Lately, BIM technology has been used in buildings domestically and proved reliable in respect of its features that enable overall comparison and prediction of housing design, performance and efficiency. The present study is to use the BIM technology to analyze energy consumption and the standard drawing schemes for rural areas to find ways to improve efficient design in singles housing sector and to suggest how to take advantage of buffer zones and how to improve housing design in favor of energy efficiency.

summary The OIKODOMOS Virtual Campus is a learning space where teachers and students of schools of architecture and urban planning collaborate in the design and implementation of learning activities dedicated to the study of housing in contemporary Europe. Its pedagogic model is based on the intertwining of on-line and on-site activities and on the integration of different types of courses following a blended learning approach. A technological platform has been specifically created to support the project’s constructivist pedagogy. In this paper we describe the main components of the pedagogic model, the technological platform, their implementation and application for delivering learning activities.

summary This paper presents considerations and refl ections based on experiments conducted in the course of cultural activities within the Hybrids Territories Project for Public Policies, fi nanced by FAPESP and in force at Nomads.usp since March 2011. Starting from previous experiences using classical methods of qualitative research, such as semi-structured interviews and questionnaires, other ways of approaching and understanding the complexity of urban and social realities were sought. The reflections here presented were formed from the trial of methodological procedures, derived from other fields of knowledge and practices already recurrent in some communities. The aim is to verify the limits and potentialities of previously tested procedures and instruments, structured through digital media, to understand the diversity of ways of living in social housing estates with housing units similar to each other and located in the outskirts of two different cities.

source SIGraDi 2011 [Proceedings of the 15th Iberoamerican Congress of Digital Graphics] Argentina - Santa Fe 16-18 November 2011, pp. 123-126
summary The constant discovery of new digital tools for design and representation confront us with new concepts, of- fering new theoretical perspectives on design practice. We must rethink the role of the designer and find tools to enable communication within projecting interdisciplinary teams. The future of design lies in collaboration and participation. In this paper we explore the idea of postdisciplinary design and sketch a operational theory of design based on the transposition, towards a new interfase for collaborative design that allows different ways of design and different strategies of use for each discipline involved.

title I think Therefore i-Phone: The influence of Pervasive Media on Collaboration and Multi-Disciplinary Group Work
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. 69-84.
summary The study of value and its transfer during the multi-disciplinary process of design is stable fodder for research; an entire issue of Design Studies has been devoted to Values in the Design Process. By scrutinising design meetings Dantec (2009) and Ball (2009) separately examine the mechanisms of value transfer between the agents involved in design (clients, designers, engineers). Dantec suggests this is best understood in terms of requirement, values and narrative; Ball proposes it should be viewed as a combination of "analogical reasoning" and "environmental simulation". If we look at Vitruvius and his primary architectural manual (Pollio 1960) we find values‚Äîin the form of firmitas, utilitas and venustas‚Äîembedded in this early codification of architectural practice. However, as much current research is restricted to design practice what occurs when value frameworks move between domains of cultural activity (such as design to construction and vice-versa) is not privileged with a comparably sizable body of research. This paper is concerned with the ongoing usage of pervasive media and cellular phones within communications and value transfer across the disciplinary threshold of design and construction. Through participation in a building project we analyse the subtleties of interaction between analogue communication such as sketches and digitally sponsored communication such as e-mail and mobile phone usage. Analysing the communications between the designer and builder during construction suggests it is also a creative process and the distinctions between design and construction processes are complex and often blurred. This work provides an observational basis for understanding mobile computing as a dynamic ‚Äòtuning‚Äô device‚Äîas hypothesized by Richard Coyne (2010)‚Äîthat ameliorates the brittleness of communication between different disciplines. A follow up study deploys ‚Äòdigital fieldnotes‚Äô (dfn) a bespoke iPhone application designed to test further suppositions regarding the influence exerted upon group working by mobile computing. Within collaboration individual communiqu_©s have different levels of importance depending on the specific topic of discussion and the contributing participant. This project furthers the earlier study; expanding upon what mobile computing is and enabling us to infer how these emergent devices affect collaboration. Findings from these two investigations suggest that the synchronous and asynchronous clamour of analogue and digital tools that surround design and construction are not exclusively inefficiencies or disruptions to be expunged. Observational evidence suggests they may provide contingency and continue to have value attending to the relationship between static components‚Äîand the avoidance of failure‚Äîwithin a complex system such as design and construction.

title Integrative Design Computation: Integrating material behaviour and robotic manufacturing processes in computational design for performative wood constructions
source ACADIA 11: Integration through Computation [Proceedings of the 31st Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA)] [ISBN 978-1-6136-4595-6] Banff (Alberta) 13-16 October, 2011, pp. 72-81
summary In contrast to most other building materials, wood is a naturally grown biological tissue. Today, the organic nature of wood is recognized as a major advantage. Wood is one of the very few naturally renewable, fully recyclable, extremely energy efficient and CO2-positive construction materials. On the other hand, compared to industrially produced, isotropic materials, the inherent heterogeneity and differentiated material makeup of wood’s anatomic structure is still considered problematic by architects and engineers alike. This is due to the fact that, even today, most design tools employed in architecture are still incapable of integrating and thus instrumentalizing the material properties and related complex behavior of wood. The research presented in this paper focuses on the development of a computational design approach that is based on the integration of material properties and characteristics. Understanding wood as a natural composite system of cellulose fibers embedded in a lignin and hemicelluloses matrix characterized by relatively high strain at failure, that is high load-bearing capacity with relatively low stiffness, the particular focus of this paper is the investigation of how the bending behavior of wood can become a generative design driver in such computational processes. In combination with the additional integration of the possibilities and constraints of robotic manufacturing processes, this enables the design and production of truly material-specific and highly performative wood architecture. The paper will provide a detailed explanation of such an integrative approach to design computation and the related methods and techniques. This is complemented by the description of three specific research projects, which were conducted as part of the overall research and all resulted in full scale prototype structures. The research projects demonstrate different approaches to the computational design integration of material behavior and robotic manufacturing constraints. Based on a solution space defined by the material itself, this enables novel ways of computationally deriving both material-specific gestalt and performative capacity of one of the oldest construction materials we have.

title Heavy Design
source International Journal of Architectural Computing vol. 9 - no. 3, 251-258
summary Digital tools in architecture have a powerful capability that we have only begun to explore; the questions to ask of them are perhaps not what they can do but what should we use them for? To date, much of the work done in the area of computational design has been used as elaborate patterning - some have called it ‘ornament’. The significance of this ornament is not only pleasure but in its use of digital patterns to represent our current complex and digital age.This representation in itself is not problematic; however, what is problematic is the lack of other meaningful uses of the digital form-generating tools and their distance from a culture of making. The main failing of our use of digital design (algorithmic or not) in architecture to this point is its inability to translate smoothly from the digital world to the physical world. The main reasons for this difficulty in translation are gravity and inherent material properties. Working with gravity and its physical implications is generally considered the role of the structural engineer; as such, engineers have generally created digital tools in this area.The engineer's methodology analyses a structure based on complex structural analysis programming but in order to do this, a detailed description of the structure must already exist. This is not useful in preliminary stages of design. However, the generation of architecture within an environment, which already includes structural principles, may bring us one step closer to this transition of virtual to physical by including gravity in architectural generation while not diminishing the creative form-generating process. An approach has been proposed which responds with a concept of ‘heavy design’. This type of approach incorporates logics from other disciplines, primarily structural engineering, to inform design. The design process incorporates the structural behavior of a system into the architectural model. Engineering offers a mathematical interpretation of the physical world and this is inherently suited to algorithmic design because it is already in equation form. It can thus be programmed into the architectural form generational software. The variables used in the equations become the variables within the architectural design and this inherently brings the natural physical laws to the architecture through a numerical, algorithmic method. The design produced is not a singular answer but rather a responsive vocabulary of a structural system, which is then employed in design in differing conditions. The architecture produced is both function and ornament, having cultural interpretation but carrying out many engineering tasks: a true parametric architecture.

title Sustainable Planning with a Synergetic Collation of Thermal and Dynamic Characteristics of Urban Climate using Map Based Computational Tools
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. 367-382.
summary Since 2006, half of the world’s population lives in cities. In the age of climate change, designing for quality environmental living conditions and sustainability is a topical concern. However, on the one hand, designers and city planners operate with their three dimensional city morphological data such as building shapes and volumes, forms and their spacings, and functional attributes and definition signatures. On the other hand, urban climatologists operate with their numbers and equations, quantities and signals, and normals and anomalies. Traditionally the two camps do not meet. It is a challenge to develop design tools that they can work together. Map based information system based on computational geographic information system (GIS) that is properly structured and represented offers a common language, so to speak, for the two professional groups to work together. Urban climatic map is a spatial and graphical tool with information embedded in defined layers that are collated so that planners and urban climatologists can dialogue over design issues. With various planning and meteorological data coded in defined grid resolutions onto the GIS map system, data can be synergized and collated for various understandings. This papers explains the formulation of Hong Kong’s GIS based Urban Climatic Map as an example of how the map works in practice. Using the map, zonal and district based planning decisions can be made by planners and urban climatologists that lead to new designs and policy changes.

summary This paper discusses the support of informal interaction at a distance using shared space approach. From examining existing examples, we identified critical issues and suggested that a lack of sense of shared space might be the cause of these issues. In order to understand how sense of shared space is supported in these systems, this paper introduces a taxonomy of mediated shared space for informal interaction whose categories are classified based on the degree to which the sense of shared space is supported.

title Understanding Shared Space for Informal Interaction among Geographically Distributed Teams
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. 41-54.
summary In a design project, much creative work is done in teams, thus requires spaces for collaborative works such as conference rooms, project rooms and chill-out areas. These spaces are designed to provide an atmosphere conducive to discussion and communication ranging from formal meetings to informal communication. According to Kraut et al (E.Kraut et al., 1990), informal communication is an important factor for the success of collaboration and is defined as “conversations take place at the time, with the participants, and about the topics at hand. It often occurs spontaneously by chance and in face-to-face manner. As shown in many research, much of good and creative ideas originate from impromptu meeting rather than in a formal meeting (Grajewski, 1993, A.Isaacs et al., 1997). Therefore, the places for informal communication are taken into account in workplace design and scattered throughout the building in order to stimulate face-to-face interaction, especially serendipitous communication among different groups across disciplines such as engineering, technology, design and so forth. Nowadays, team members of a project are not confined to people working in one location but are spread widely with geographically distributed collaborations. Being separated by long physical distance, informal interaction by chance is impossible since people are not co-located. In order to maintain the benefit of informal interaction in collaborative works, research endeavor has developed a variety ways to shorten the physical distance and bring people together in one shared space. Technologies to support informal interaction at a distance include video-based technologies, virtual reality technologies, location-based technologies and ubiquitous technologies. These technologies facilitate people to stay aware of other’s availability in distributed environment and to socialize and interact in a multi-users virtual environment. Each type of applications supports informal interaction through the employed technology characteristics. One of the conditions for promoting frequent and impromptu face-to-face communication is being co-located in one space in which the spatial settings play as catalyst to increase the likelihood for frequent encounter. Therefore, this paper analyses the degree to which sense of shared space is supported by these technical approaches. This analysis helps to identify the trade-off features of each shared space technology and its current problems. A taxonomy of shared space is introduced based on three types of shared space technologies for supporting informal interaction. These types are named as shared physical environments, collaborative virtual environments and mixed reality environments and are ordered increasingly towards the reality of sense of shared space. Based on the problem learnt from other technical approaches and the nature of informal interaction, this paper proposes physical-virtual shared space for supporting intended and opportunistic informal interaction. The shared space will be created by augmenting a 3D collaborative virtual environment (CVE) with real world scene at the virtual world side; and blending the CVE scene to the physical settings at the real world side. Given this, the two spaces are merged into one global structure. With augmented view of the real world, geographically distributed co-workers who populate the 3D CVE are facilitated to encounter and interact with their real world counterparts in a meaningful and natural manner.

It investigates the possibilities for producing volumetric tetrahedral meshes based on the interactions of individual stochastic agents. The research situates itself at the intersection of the visual arts, the physical sciences, and computer science. The basic interest in stochastics comes from the visual arts; the growth simulation approach is borrowed from the natural sciences; and the use of a tetrahedral mesh within C++ comes from computer science. But more generally, the project focuses on architecture’s ongoing engagement with stochastic systems. By embedding extremely specific tendencies within an agent’s behavior, while also allowing for stochastic variation, we can create larger systems that are both in and out of our “control”. This sidesteps the typical limitations of many computational geometry and parametric methods, where there is often an overly deterministic relationship between the input and output of a given system. Such a shift from optimization to behavior inevitably brings up troubling questions of style. Abandoning the search for a “best” solution, or even the articulation of the criteria for such a task, re-opens computational architecture at its deepest levels as a site for design speculation.
