title	An Urban Information Framework to support Planning, Decision-Making & Urban 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. 653-668.
summary	This paper reports on a 2-year research project undertaken in collaboration with a state planning authority, a major city municipal council and a government-owned development organisation. The project has involved the design of an urban information model framework with the aim of supporting more informed urban planning by addressing the intersection where an individual building interfaces with its urban context. This adopted approach enables new techniques that better model the city and its processes in a transparent and accessible manner. The primary driver for this project was the challenge provided by the essential incompatibility between legacy GIS (geographic information system) datasets and BIM (building information model) representations of the built form. When dealing with urban scale information, GIS technologies use an overlay mapping metaphor linked to traditional relational database technologies to identify features or regions in the urban landscape and attach attribute data to those in order to permit analysis and informed assessment of the urban form. On the other hand, BIM technologies adopt an object-oriented approach to model the full three-dimensional characteristics of built forms in a way that captures both the geometric and physical attributes of the parts that make up a building, as well as the relationships between those parts and the spaces defined by the building fabric. The latter provides a far richer semantic structure to the data, while the former provides robust tools for a wide range of urban analyses. Both approaches are widely recognised as serving well the needs of their respective domains, but there is a widespread belief that we need to reconcile the two disparate approaches to modelling the real world. This project has sought to address that disjunction between modelling approaches. The UrbanIT project concentrated on two aspects of this issue: the development of a framework for managing information at the precinct and building level through the adoption of an object-oriented database technology that provides a platform for information management; and an exploration of ontology tools and how they can be adopted to facilitate semantic information queries across diverse data sources based on a common urban ontology. This paper is focussed on the first of those two agendas, examining the context of the work, the challenges addressed by the framework and the structure of our solution. A prototype implementation of the framework is illustrated through an urban precinct currently undergoing renewal and redevelopment, finishing with a discussion of future work that comes out of this project. Our approach to the implementation of the urban information model has been to propose extensions to ISO/PAS 16739, the international standard for modelling building information that is commonly known as IFC (Industry Foundation Classes). Our reason for adopting that approach is primarily our deep commitment to the adoption of open standards to facilitate the exchange of information across the built environment professions, but also because IFC is based on a robust object schema that can be used to construct a internet-accessible database able, theoretically, to handle the vast quantity of data needed to model urban-scale information. The database solution comes with well-established protocols for handling data security, integrity, versioning and transaction processing or querying. A central issue addressed through this work is concerned with level of detail. An urban information model permits a very precise and detailed representation of an urban precinct, while many planning analyses rely on simplified object representations. We will show that a key benefit of our approach is the ability to simultaneously maintain multiple representations of objects, making use of the concept of model view definitions to manage diverse analysis needs.

title	Applying interpretation-driven association to design domains
doi	https://doi.org/10.52842/conf.caadria.2011.453
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. 453-462
summary	This paper presents a computational model of visual association- making. Our model focuses on the interaction between the processes of representation and matching in association. Re-interpretation of the objects being associated changes the landscape in which the matching process is searching for potential mappings between those objects. We call this process interpretation-driven search. We demonstrate the capabilities of our system through some examples of previous work in simple shape domains, then discuss ongoing research into applying this system to design domains.

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	Digital tea house: Japanese tea ceremony as a pretext for exploring parametric design and digital fabrication in architectural education
doi	https://doi.org/10.52842/conf.caadria.2011.071
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. 71-80
summary	This paper reviews the Digital Tea House, a joint workshop in August of 2010 held at the University of Tokyo, Department of Architecture, together with Columbia University GSAPP. Three pavilions for hosting ceremony were designed and built in less than one month, in an attempt to bridge technology and culture not only through design but also fabrication. Issues addressed in the process included applications of computational design, interpretations of tradition and culture in spatial or activity oriented expressions, structural stability, to practical solutions for quick physical materialization. Three teams comprised of 6 to 8 students, each a blend of different nationalities, ultimately produced 3 full-scale tea houses with the same software, primary material, budget, and principal fabrication method.

title	Decoding Culture Parametrically: Digital Tea House Case Studies
source	International Journal of Architectural Computing vol. 9 - no. 4, 325-338
summary	This paper reviews the Digital Tea House, a workshop held at the University of Tokyo with the aim to build three pavilions for hosting tea ceremony.As first attempts on cultivating formal innovations resulting from digital design process applied to construction of tea houses, the works convey that parametric design can be a mechanism through which architects are able to produce new images of a tea house and renew its conceptual meanings, and that it can be a tool to retain architecture convergent with cultural values.The authors analyze issues addressed in the workshop that range from applications of computational design, interpretations of tradition, structural stability, to solutions for quick physical materialization within limited time and budget.This paper clarifies the following: First, that parametric processes are not contradictory to traditional cultural principles; and second, how traditional elements of the tea house were decoded and formally reinterpreted through parametric designs.

title	Informing Architecture and Urban Modeling with Real-world Data on 3D Tangible Interfaces and Augmented Displays
doi	https://doi.org/10.52842/conf.acadia.2011.226
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. 226-233
summary	The proliferation of online and digital data in our world yields unprecedented opportunities for connecting physical and digital parametric models with live data input and feedback. Tangible interfaces and augmented displays provide theatrical settings for designers to visualize real-world data and experience realtime feedback while manipulating physical and digital models on the table. This paper proposes a new approach to design workflow, where physical model and virtual model can be interconnected and informed in realtime by multiple analytical datasets and live data streams. Using 3D scanning, blob detection, and multi-touch techniques, multidimensional tangible interfaces and augmented displays presented in this paper demonstrate a powerful new approach for designing and interacting with physical models, materials, and environmental data.

title	Active buildings: What can we do about buildings that simply stand still?
doi	https://doi.org/10.52842/conf.caadria.2011.301
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. 301-310
summary	This paper presents background of our research and result of our pilot study to find methods for convincing building users to become active building participants. We speculate this is possible by allowing and motivating users to customise and manage their own built environments. The ultimate aim of this research is to develop open, flexible and adaptive systems that bring awareness to building users to the extent they recognise spaces are for them to change rather than accept spaces are fixed and they are the ones to adapt. We argue this is possible if the architectural hardware is designed to adapt to begin with and more importantly if there are appropriate user interfaces that are designed to work with the hardware. A series of simple prototypes were made to study possibilities through making, installing and experiencing them. Ideas discussed during making and experiencing of prototypes were evaluated to generate further ideas. This method was very useful to speculate unexplored and unknown issues with respect to developing user interfaces for active buildings.

title	Closing the loop of design and analysis: Parametric modelling tools for early decision support
doi	https://doi.org/10.52842/conf.caadria.2011.525
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. 525-534
summary	There is a growing need for parametric design software that communicates building performance feedback in early architectural exploration to support decision-making. This paper examines how the circuit of design and analysis process can be closed to provide active and concurrent feedback between architecture and services engineering domains. It presents the structure for an openly customisable design system that couples parametric modelling and energy analysis software to allow designers to assess the performance of early design iterations quickly. Finally, it discusses how user interactions with the system foster information exchanges that facilitate the sharing of design intelligence across disciplines.

title	Energy-Oriented Design Tools for Collaboration in the Cloud
source	International Journal of Architectural Computing vol. 9 - no. 4, 339-359
summary	Emerging from the challenge to reduce energy consumption in buildings is the need for energy simulation to be used more effectively to support integrated decision making in early design.As a critical response to a Green Star case study, we present DEEPA, a parametric modeling framework that enables architects and engineers to work at the same semantic level to generate shared models for energy simulation.A cloud-based toolkit provides web and data services for parametric design software that automate the process of simulating and tracking design alternatives, by linking building geometry more directly to analysis inputs. Data, semantics, models and simulation results can be shared on the fly.This allows the complex relationships between architecture, building services and energy consumption to be explored in an integrated manner, and decisions to be made collaboratively.

title	Scripted Materials
doi	https://doi.org/10.52842/conf.acadia.2011.204
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. 204-211
summary	Looking to fabrication technologies as a way to bridge the gap between design and execution, this research tested various methods for the digital optimization of flat sheet materials, specifically those which can be reclaimed from building and manufacturing sites. By reordering conventional design processes to begin with (reclaimed) material constraints we are looking to close the gap in the cycle of sheet material manufacturing and reduce the amount of building waste in architectural projects. This paper will discuss the process of embedding digital information and scripting processes into material systems in order to rethink the relationship between input and output in design, especially in the context of sheet material manufacturing, reclamation, fabrication and distribution. Two projects situated within architectural design studios are cited as examples to this approach, with speculation on how the work might shift the role of ‘craft’ in design and fabrication processes.
