title	Co-operation and Complicity Voices, Robots, and Tricksters in the Digital Marketplace
source	International Journal of Architectural Computing vol. 5 - no. 1, pp. 162-175
summary	We advocate the theme of complicity, ahead of co-operation, as a means of understanding complex, interactive digital systems. Our case study of a market precinct known as the Barras, about one mile from the centre of the city of Glasgow, foregrounds the notion of complicity. Market places are characterized not only by co-operation in rule-governed environments, but complicity between actors as a means of breaking rules, working at the boundaries of formal frameworks, avoiding other actors, such as law enforcers, and even working with them in tacitly agreed evasion strategies. We present the human voice (as exercised in the case of market stall holders drawing attention to their wares) as a major medium of complicity. In our application of these ideas we deploy Lego Mindstorms TM RCX robot processing to explore interactions between a mobile sensing robot and simple environmental controls: movements of sliding screens in response to an autonomous mobile sensor. As well as their benign characteristics as co-operating agents, we argue for a consideration of robots as quintessential tricksters, plotting and scheming strategies of survival, evasion and opportunism. Traits that can be employed in the development of useful augmented environments.

title	The Role of Higher Education in nD Modelling Implementation
source	Constructing the Future: nD modelling, Ghassan Aouad, Angela Lee, Song Wu, Taylor & Francis Books Ltd, pp. 309-325 2007
summary	University education is no stranger to change, but the rapid development of today’s information technology (IT) is posing great challenges to academics who have to consider its appropriate integration into carefully designed curricula to meet the expectation of students and the requirements of industry. A more widespread acceptance of 3D modelling within organizations is seen as a significant milestone in advancing the adoption of nD modelling technology and furthering the vision for a single integrated project model shared by the key participants in the design and construction process.

title	The development of an augmented reality-based user interface to support maintenance fieldwork
source	Em‘body’ing Virtual Architecture: The Third International Conference of the Arab Society for Computer Aided Architectural Design (ASCAAD 2007), 28-30 November 2007, Alexandria, Egypt, pp. 35-42
summary	This paper discusses computational support for the maintenance of Mechanical, Electrical, and Plumbing (MEP) systems to more effectively use maintenance information. A common cause of inefficient and ineffective maintenance has been the difficulty in getting reliable, just-in-time information for in-situ maintenance work. To reduce this inefficiency in the maintenance environment, accessibility and accuracy of maintenance information must be improved. Our approach, therefore, is the development of a user interface that will produce superimposed computer graphics of equipment/facility-specific maintenance information onto a live video stream on portable computing devices, such as laptops and PDAs. This paper concentrates on elicitation of primary functions needed to support various maintenance activities as well as a prototype application being developed for the approach.

title	Fuzzy-Based Direct Manipulation: Focused on User Participation in Apartment Plan Design Process
doi	https://doi.org/10.52842/conf.caadria.2007.x.c0b
source	CAADRIA 2007 [Proceedings of the 12th International Conference on Computer Aided Architectural Design Research in Asia] Nanjing (China) 19-21 April 2007
summary	Physically-based manipulation can be recognized as a promising approach to implement interactive computational tools to solve the user participation problems. To support the designer’s justifications as well as to clarify the innately ambiguous expressions provided by the clients, we propose to build a fuzzy-based expert system integrated with a 3D physically based manipulation. This paper focuses on a system prototype for the client customization process in apartment plan design to exemplify our concepts.

title	Plan_B: The architectonics of sonic information
source	Em‘body’ing Virtual Architecture: The Third International Conference of the Arab Society for Computer Aided Architectural Design (ASCAAD 2007), 28-30 November 2007, Alexandria, Egypt, pp. 587-594
summary	The paper addresses the influence of digital technology on architectural design and production, particularly considering the possibilities of sound for the design and conception of architecture based on the dynamic condition, which is present in the “everyday” and its permutations. The day-to-day condition is regarded as a highly dynamic flux of economic, social and political aspects and conceptually linked to sound and musical variation as guiding design principles, to actually retain and reflect the vitality of every day’s measure. We have traced precedents and cases in sound reproduction and its implications on the codification of architecture and have created a digital design tool in Max/MSP. The primary objective of the tool is to produce the corollary between sound reproduction and the conception and production of an architectonic codification, and ultimately to propose a strategy of architectural construct that has given way from the clarity of static geometry to the complexity in dynamic variability, that of dissonance. Virtual architecture and its techniques are considered to express and implement such permutations and induce a measure of change in every step and direction of the design process. The application of digital technology is regarded as the intervening of “apparatus” and to represent a different approach in relation to the prevailing regime.

title	Personal Assistant: Autonomous Agents Base on Multi-Agent System among Different Industrial Design Stakeholders
doi	https://doi.org/10.52842/conf.caadria.2007.x.f2e
source	CAADRIA 2007 [Proceedings of the 12th International Conference on Computer Aided Architectural Design Research in Asia] Nanjing (China) 19-21 April 2007
summary	To deal with complex communication problems, requires both a web-based collaborative system and a multi-agent system (MAS) integrated with knowledge management architecture. Agents have been acknowledged as a promising approach through the metaphor that an agent can act as a personal assistant. In this paper we proposes an approach to develop personal assistant agents, each of which can represent a different stakeholder and load different domain knowledge inside. To demonstrate our proposed concepts, we focus on a prototype system for notebook design for the company ASUS, a leading notebook manufacturer based in Taiwan.

summary	The Intranet/Internet based Web computing has been one of the most exciting applications to everybody in any fields. Unfortunately most of the commercial CAD systems or engineering management information systems today lack adequate supports to Intranet and Internet. In this paper we will introduce our recent research and developing work on the Architectural Design Schema Management System (ADSMS) that is essentially a WEB application and is a multimedia engineering information management system. It is first designed to meet the needs of architects to support their design work via Intranet/Internet, and at the same time to lay a solid foundation for further development of the CAAD system that is based on internet.

title	The Effect of Hygroscopic Design Parameters on the Programmability of Laminated Wood Composites for Adaptive Façades
source	Ji-Hyun Lee (Eds.) "Hello, Culture!" [18th International Conference, CAAD Futures 2019, Proceedings / ISBN 978-89-89453-05-5] Daejeon, Korea, p. 435
summary	Typical adaptive façades respond to external conditions to enhance indoor spaces based on complex mechanical actuators and programmable functions. Hygroscopic embedded properties of wood, as low-cost low-tech programmable material, have been utilized to induce passive motion mechanisms. Wood as anisotropic material allows for different passive programmable motion configurations that relies on several hygroscopic design parameters. This paper explores the effect of these parameters on programmability of laminated wood composites through physical experiments in controlled humidity environment. The paper studies variety of laminated configurations involving different grain orientations, and their effect on maximum angle of deflection and its durability. Angle of deflection is measured using image analysis software that is used for continuous tracking of deflection in relation to time. Durability is studied as the number of complete programmable cycles that wood could withstand before reaching point of failure. Results revealed that samples with highest deflection angle have least programmability durability.

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

title	Efficient Alias-Free Rendering using Bit-masks and Look-up Tables
source	SIGGRAPH '85 Conference Proceedings. July, 1985. vol. 19 ; no. 3: pp. 53-59 : ill. (some col.). includes bibliography
summary	The authors demonstrate methods of rendering alias-free synthetic images using a precomputed convolution integral. The method is based on the observation that a visible polygon fragment's contribution to an image is solely a function of its position and shape, and that within a reasonable level of accuracy, a limited number of shapes represent the majority of cases encountered in images commonly rendered. The basic technique has been applied to several different rendering algorithms. A version of the newly non-uniform sampling technique implemented in the same program but with different tables values was introduced

summary	The design inspired by nature is an ongoing issue from the past to the present. There are many design examples inspired from nature. Fractal geometry formation, which is focused on this study, is a system seen in nature. A model based on fractal growth principle was proposed for tile design. In this proposal made with using Visual Programming Language, a tiling design experiment placed in a hexagonal grid system was carried out. Thus, a base was created for tile designs to be made using the fractal principle. The results of the case study were evaluated and potential future studies were discussed.

title	The influence of Saudi Arabian culture on energy use: Improving the time-use schedules in energy simulation for houses in Riyadh
source	Ji-Hyun Lee (Eds.) "Hello, Culture!" [18th International Conference, CAAD Futures 2019, Proceedings / ISBN 978-89-89453-05-5] Daejeon, Korea, pp. 273-289
summary	Culture influences the way that people act and behave in all societies. In Saudi Arabia, culture and beliefs directly influence the lifestyle and behaviour of its citizens. Culture also impacts on energy usage of buildings, but this factor is often excluded from energy use simulations. A consequence of this is a mismatch between energy prediction and real energy usage. This paper demonstrates how a time-use data (TUD) model can be used to create a more realistic estimate of energy consumption in Saudi Arabia. TUD has been collected through a survey of 300 people living in Riyadh. The performance of the computational TUD model is cross-referenced with empirical data and the outcomes are used to discuss how the TUD model can be applied more effectively in energy use simulations.

source	Proceedings of the Ninth International Conference on Computer Aided Architectural Design Futures [ISBN 0-7923-7023-6] Eindhoven, 8-11 July 2001, pp. 739-752
summary	In this paper, an Interactive Rendering System for Animated Assessment (IRSA2) is proposed. Using IRSA2, different to the usual process that the respondents are allowed only to select alternatives designed by planners, they are allowed to participate in the design process and create alternatives as proposals in a web-based collaborative environment. This gives roads to an autonomous process in landscape planning and design. The system efficiency was verified by a case study of its use in a wind farm project in Japan.

summary	This paper focuses on developing a novel geo-computational methodology for automating the generation of design options for district planning. The knowledge contribution focuses on the ability of the planners and designers to interact with and override the automated process. This approach is referred to as "agile automated modelling". The approach is demonstrated through a case study in which three adjacent districts are generated with a total area of approximately 1300 hectares. An automated modelling process is implemented based on a set of core planning principles established by the planners. The automated process generates street networks, land parcels, and 3-dimensional urban models. The process is broken down into three steps and users are then able to intervene at the end of every step to override and modify the outputs. This aims to help planners and designers to iteratively generate and assess various planning outcomes.

summary	This paper introduces a novel framework for urban analysis that leverages computational techniques, along with established urban research methods, to study how people use urban public space. Through three case studies in different urban locations in Europe and the US, it demonstrates how recent machine learning and computer vision techniques may assist us in producing unprecedently detailed portraits of the relative influence of urban and environmental variables on people’s use of public space. The paper further discusses the potential of this framework to enable empirically-enriched forms of urban and social analysis with applications in urban planning, design, research, and policy.

title	Weeping Brick The Modular Living Wall System Using 3D Printed Porous Ceramic Materials
source	Ji-Hyun Lee (Eds.) "Hello, Culture!" [18th International Conference, CAAD Futures 2019, Proceedings / ISBN 978-89-89453-05-5] Daejeon, Korea, p. 437
summary	The goal of this research is to design and fabricate a modular living wall brick system that purifies and cools air for various indoor environments. The research utilizes ceramic 3d printing techniques for fabrication; and living plants in conjunction with evaporative cooling techniques for indoor air quality control. The brick is made of soil which become porous after firing or drying. Water from the reservoirs slowly weep through the porous brick, creating a layer of water on the surface of the brick. The air movement around the saturated brick creates evaporative cooling and the hydro-seeded plants absorb water from the surface. The shape and texture of the Weeping Brick maximizes the cooling effect via large surface area. As an aggregated wall system, the water circulates from unit to unit by gravity through interconnected reservoirs embedded within each unit. The plants and moss transform the Weeping Brick into a living wall system, purifying and conditioning the indoor air.
