title Design Flow and Ideation
source International Journal of Architectural Computing vol. 6 - no. 3, pp. 299-316
summary In the last year, we developed the Hybrid Ideation Space (HIS), an innovative immersive sketching and model-making system that augments analog tools with digital capabilities, for continue and direct reflective conversation with the representation. The system enables designers to sketch and make models all around them in real-time and real scale using a digital tablet (sketches), image capture (physical models) and a spherical projection device (immersion). Teams of industrial design students participated in the study working on the initial stages of the design of a car. This is a comparative study putting side by side the HIS, analog tools and hybrid modeling techniques. We developed the notion of Design Flow to assesses the design ideation process. The students reported being in the state of flow more often in the HIS than with digital or physical modeling.

title Elemental Methods for Integrated Architectures: Experimentation with Design Processes for Cable Net Structures
source International Journal of Architectural Computing vol. 6 - no. 4, 453-475
summary Tension active systems are compelling architectural structures having an intimate connection between structural performance and the arrangement of material. The direct flow of structural forces through the material makes these systems attractive and unique from an aesthetic point of view, but they are a challenge to develop from a design and an engineering perspective. Traditional methods for solving such structural systems rely on both analog modeling techniques and the use of highly advanced engineering software. The complexity and laborious nature of both processes presents a challenge for iterating through design variations. To experiment with the spacemaking capabilities of tension active systems, it is necessary to design methods that can actively couple the digital simulation with the analog methods for building the physical structure. What we propose is a designer-authored process that digitally simulates the behaviors of tension active systems using simple geometric components related to material and structural performance, activated and varied through elemental techniques of scripting. The logics for manufacturing and assembly are to be embedded in the digital generation of form. The intention is to transform what is a highly engineered system into an architectural system where investigation is as much about the determination of space and environment as it is about the arrangement of structure and material.

title The Generative Multi-Performance Design System
source Silicon + Skin: Biological Processes and Computation, [Proceedings of the 28th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) / ISBN 978-0-9789463-4-0] Minneapolis 16-19 October 2008, 448-457
summary This paper proposes a framework for an integrated computational design system. This design system builds on the strengths inherent in both generative synthesis models and multi-performance analysis and optimization. Four main design mechanisms and their mathematical models are discussed and their integration proposed. The process of building the design system begins by a top-down decomposition of a design concept. The different disciplines involved are decomposed into modules that simulate the respective design mechanisms. Subsequently through a bottom-up approach, the design modules are connected into a data flow network that includes clusters and subsystems. This network forms the Generative Multi-Performance Design System. This integrated system acts as a holistic structured functional unit that searches the design space for satisfactory solutions. The proposed design system is domain independent. Its potential will be demonstrated through a pilot project in which a multi-performance space planning problem is considered. The results are then discussed and analyzed.

title Digital design and manufacture based on Chiloean boats
source International Journal of Architectural Computing vol. 6 - no. 3, pp. 317-333
summary This paper proposes a design methodology for the manufacture of complex, double-curved surfaces based on the digital reconstruction of traditional structural and constructive elements of Chiloean boats. It also suggests a beneficial association between digital design and CAD CAM for manufacture using locally crafted construction techniques. The incorporation of innovated contemporary digital design and fabrication tools into traditional construction systems, aims to optimize and perpetuate traditional artisanal craft construction of complex shapes developed in the south of Chile. The importance of this research in budget-restricted economies, lies in the possibility of applying local construction and assembly techniques to new sophisticated designs that may satisfy the country's architectural needs. Scale models are used to record the design process and constructive development while information flow charts document the design methodology for the construction of complex geometries.

title Road hierarchy and speed limits in Brasília/Brazil
source H.J.P. Timmermans, B. de Vries (eds.) 2008, Design & Decision Support Systems in Architecture and Urban Planning, ISBN 978-90-6814-173-3, University of Technology Eindhoven, published on CD
summary This paper aims at exploring the theory of the Social Logic of Space or Space Syntax as a strategy to define parameters of road hierarchy and, if this use is found possible, to establish maximum speeds allowed in the transportation system of Brasília, the capital city of Brazil. Space Syntax – a theory developed by Hillier and Hanson (1984) – incorporates the space topological relationships, considering the city shape and its influence in the distribution of movements within the space. The theory’s axiality method – used in this study – analyses the accessibility to the street network relationships, by means of the system’s integration, one of its explicative variables in terms of copresence, or potential co-existence between the through-passing movements of people and vehicles (Hillier, 1996). One of the most used concepts of Space Syntax in the integration, which represents the potential flow generation in the road axes and is the focus of this paper. It is believed there is a strong correlation between urban space-form configuration and the way flows and movements are distributed in the city, considering nodes articulations and the topological location of segments and streets in the grid (Holanda, 2002; Medeiros, 2006). For urban transportation studies, traffic-related problems are often investigated and simulated by assignment models – well-established in traffic studies. Space Syntax, on the other hand, is a tool with few applications in transport (Barros, 2006; Barros et al, 2007), an area where configurational models are considered to present inconsistencies when used in transportation (cf. Cybis et al, 1996). Although this is true in some cases, it should not be generalized. Therefore, in order to simulate and evaluate Space Syntax for the traffic approach, the city of Brasília was used as a case study. The reason for the choice was the fact the capital of Brazil is a masterpiece of modern urban design and presents a unique urban layout based on an axial grid system considering several express and arterial long roads, each one with 3 to 6 lanes,

title Using Project Information Clouds to Preserve Design Stories within the Digital Architecture Workplace
source First International Conference on Critical Digital: What Matters(s)? - 18-19 April 2008, Harvard University Graduate School of Design, Cambridge (USA), pp. 99-104
summary During the development of an architectural design a series of design stories form. These stories chronicle the collective decision making process of the diverse project team. Current digital design processes often fail to record these design stories because of the emphasis placed on the concise and accurate generation of the virtual model. This focus on an allencompassing digital model is detrimental to design stories because it limits participation, consolidates information flow and risks editorialisation of design discussion. Project Information Clouds are proposed as a digital space for design team participants to link, categorise and repurpose existing digital information into comprehensible design stories in support of the digital building model. Instead of a discrete tool, the Project Information Cloud is a set of principles derived from a proven distributed information network, the World Wide Web. The seven guiding principles of the Project Information Cloud are simplicity, modular design, decentralisation, ubiquity, information awareness, evolutionary semantics and context sensitivity. These principles when applied to the development of existing and new digital design tools are intended to improve information exchange and participation within the distributed project team.

title Hybrid Studio Matters: Ethnomethodological Documentary of a Tutorial
source First International Conference on Critical Digital: What Matters(s)? - 18-19 April 2008, Harvard University Graduate School of Design, Cambridge (USA), pp. 23-34
summary This paper looks into the electronically augmented, or ‘hybrid’ contemporary environment, through the spatial and temporal thresholds or ‘seams’ that it encompasses. Electronically augmented environments have been studied increasingly within the past few years. The question of how architects respond to the new spatial conditions, how they interpret and design space, is a major emerging issue. Within these broad questions, we conducted an ethnomethodological analysis of a particular environment-example: the architectural design studio, through the documentation and analysis of an episode in an architectural tutorial. The analysis of this case-study is based upon the seams, the thresholds or ruptures that occur between different media. We argue that the shift or transition from one medium to another can be smooth and un-noticed, whereas, in other instances, it shifts completely the centre of attention, the flow of the tutorial or the perception of the means (and other elements) engaged. The transitions, occurring within the recorded tutorial, are studied in relation to the notions of engagement, immediacy and continuity. We consider that these three notions bring forth the complexities, conflicts and richness (of the hybrid environment) that the tutorial recording reveals.

source First International Conference on Critical Digital: What Matters(s)? - 18-19 April 2008, Harvard University Graduate School of Design, Cambridge (USA), pp. 245-251
summary Meaning in architecture has isotropic instances of realization, one that can unfold during the design process and one that can be layered onto the artifact of the building; its components and forms constitute a communication flow that emerges from an abstract form of description to its physicality. The internal cognition of this condition situates the subject as the third element, one that identifies the meaning from the extant building to its proxy meaning. In this manner, narrative and aesthetics perform the actualizations (the spatial and physical sequences) so that the occupant may understand its implications.1 Architecture is thus a one-directional flow of information (the building is an inert object from which meaning is derived, its physicality is static). Even in process-driven design, the synthesis of the many and the ordered, is evident in the materiality of the architectural manifestation; the building, although presented as a result of process cannot be separated from the reading of the generative operations. 2 Rather than continue in this manner of constructing meaning from an extensive coding (joining a concept to an object) or the instantiation (producing one from a larger field of possibilities) from a version, we suggest a dialectic that is bi-directional, or even multinodal, that is, continually self-renewing in meaning and material configuration with the active participation of the occupant. This representation is one that is time-based.

title Analyzing Pedestrian Movement in Mataf Using GPSand GIS to Support Space Redesign
source H.J.P. Timmermans, B. de Vries (eds.) 2008, Design & Decision Support Systems in Architecture and Urban Planning, ISBN 978-90-6814-173-3, University of Technology Eindhoven, published on CD
summary Evaluating the use of architectural and urban spaces is an important issue for architects and urban designers who wish to enhance space usability. Space usability is crucial in crowded spaces such as Mataf areas. Millions of people come to the city of Makkah, Saudi Arabia every year to perform Hajj (Islamic Pilgrimage) and Umrah. A cornerstone of Hajj and Umrah spirituals is to perform Tawaf, which is the circumambulation of the Ka'bah in the center of the Holy Mosque in Makkah. The areas of performing Tawaf (called Mataf) become very crowded during Hajj and the last ten days of Ramadan. This paper demonstrates how we utilized Global Positioning Systems (GPS) and Geographic Information Systems (GIS) to analyze pedestrian movement while performing Tawaf. During the Hajj of 1424 H (2004 in the Georgian Calendar), several GPS devices were used to collect pedestrian movement coordinates at specific time intervals. Computer software for tracking analysis is used to visualize and analyze the pattern of pedestrian movement in Tawaf. The software allows users to view temporal data, which can be set up with past time windows for historical data analysis. The findings of this research show levels of service and flow rates throughout different zones and times of Mataf. They indicate the most critical zones and times for Tawaf during Hajj. They also visually demonstrate the track pattern of pedestrian movement at different locations in the Tawaf area. The paper concludes with some redesign recommendations to remove obstacles and facilitate pedestrian movement in Tawaf. The approach described in this paper can be implemented in architectural and urban design space modifications to improve pedestrian movement in open spaces.

title The Thermal Organism And Architecture

summary Throughout the history of architectural discourse the concept of metabolic function in a building and a buildings relationship to its creators is expressed by keen designers who understand the subtle linkage. Organistic homeostasis is a biological function found in all mammals including humans. The interior generation of heat classifies man as endothermic. Endothermic heat generation allows for a very controlled equilibrium and is a characteristic of more complex organisms. The body has produced highly evolved surface systems to help efficiently manage the flow of heat energy in and out of the body. I suggest building envelopes represent the human being projecting itself outwards in a prosthetic extension of the skin. Inherent in this projection are the same demands of envelope put forth in the body. In my research of anatomy I have found one system that has evolved to help facilitate endothermic heat regulation in mammals at the skin level, which is hair. How does hair transcribe into architecture? An analysis into the function of hair and its adaptable morphologies is studied. Hair is a thermal regulating system, its building equivalent are forms of thermal insulation and radiant barriers. Hairs goal is homeostatic equilibrium which has its architectural counterpoint known as the balance point. Hair is an adjustable system that mitigates between internal and external heat loading which is the goal of a building envelope. In conclusion the paper explores these issues and more in new building systems and design tactics that originate from the function of hair.

title Development of a Simple Web-based GIS System for Sustainable Housing Projects VisualizatioN
source CAADRIA 2008 [Proceedings of the 13th International Conference on Computer Aided Architectural Design Research in Asia] Chiang Mai (Thailand) 9-12 April 2008, pp. 236-243
summary This paper presents a simple web-based GIS system for visualization of Baan Mankong, as known as sustainable housing projects for communities of low-incomers in Thailand. The Baan Mankong project has been so successful that numbers of projects initialized have been increasing during the past couple of years. The projects information is gathered in a huge database, but there is a lack of visualization tool to help the officers and executives to have a global view of the projects’ spatial distribution and to have a quick access to project information. GIS is proposed as a tool to be developed on the web for the visualization of this project. The Baan Mankong’s work flow and project information are studied in order to select only necessary information to be stored in the system. Then, the geographic visualization tool development process is presented.

title Go with the flow: particle systems for program modeling in high-rise buildings
source International Journal of Architectural Computing vol. 6 - no. 2, pp. 171-196
summary This paper revisits the particle flow system, a time-based computational tool, which has received a lot of attention from the early pioneers of digital architecture. The use of particle flow systems in architecture enables designers to materialize what they term as site forces which can later be formalized into a building. The methods offered by various designers for using particle flow systems in architecture have kept the discourse purely formal by focusing on the exterior and neglecting the interior. This paper offers a different way of using and conceptualizing particle flow systems in architecture. Shifting the emphasis from the formal, the paper aims to show the potential of using particle flow systems as a parametric model for exploring the spatial organization of an architectural program. This paper also illustrates the application of the proposed computational model, i.e., the particle flow system, by using a case study - the design of a high-rise building in downtown Tel Aviv, Israel.

summary This paper reports on work carried out within the Cityware project using mobile technologies to map, visualise and project the digital co-presence in the city. This paper focuses on two pilot studies exploring the Bluetooth landscape in the city of Bath. Here we apply adapted and ‘digitally augmented’ methods for spatial observation and analysis based on established methods used extensively in the space syntax approach to urban design. We map the physical and digital flows at a macro level and observe static space use at the micro level. In addition we look at social and mobile behaviour from an individual’s point of view. We apply a method based on intervention through ‘Sensing and projecting’ Bluetooth names and digital identity in the public arena. We present early findings in terms of patterns of Bluetooth flow and presence, and outline initial observations about how people’s reaction towards the projection of their Bluetooth names practices in public. In particular we note the importance of constructing socially meaningful relations between people mediated by these technologies. We discuss initial results and outline issues raised in detail before finally describing ongoing work.

title Rapid Agent Based Simulation of People Flow forDesign of SpacesAnalysis, Design and Optimisation
source H.J.P. Timmermans, B. de Vries (eds.) 2008, Design & Decision Support Systems in Architecture and Urban Planning, ISBN 978-90-6814-173-3, University of Technology Eindhoven, published on CD
summary This paper presents a novel static-dynamic network based people flow simulation model applied to design optimisation of circulation spaces within buildings and urban areas. In the current state of art the majority of existing people flow simulation models are driven by analysis rather than design. This is fine for simpler, evacuation type scenarios where a single or a few analyses runs are sufficient to determine the evacuation time. For more complex scenarios such as crowd circulation with complex multi-directional flow, one is as interested in the sensitivity of various design and stochastic behavioural parameters, so the rapid modelling simulations together with design capability become important. This paper presents a simplified network based people flow model that enables rapid simulations and therefore iterative design optimization of circulation space. The work integrates the techniques of graph-theory based network analysis with an origin-destination matrix model of crowd flow, to provide a rapid, parametric model. The resulting model can be analysed in a static as well as dynamic state. In the static state, the model analyses space based on connectivity of nodes, superimposed with the origin-destination matrix of population to provide valuable information such as footfalls, density maps, as well as quasi-static parameters such as mean flow rates. In the dynamic state, the model allows time-dependent analysis of flow using a detailed agent based simulation that also incorporates dynamic route-choice modelling, agent behaviours and interaction, and stochastic variations. The paper presents the integrated modelling technique and its implementation into simulation software SMART Move.

title Multi-Directional Interrelationship Approach For Hybrid Interactive Design Tool For High-Rise Building
source CAADRIA 2008 [Proceedings of the 13th International Conference on Computer Aided Architectural Design Research in Asia] Chiang Mai (Thailand) 9-12 April 2008, pp. 110-116
summary The role of computers in architectural design is constantly increasing, as may be seen in the efforts to develop generative design tools which are focused on helping create innovative results. Some of these are generated by sets of rules, constraints, theoretical models and algorithms, for which the computer is used as the implementing tool. This research introduces a new approach in hybrid interactive design tools, which are focused on the clustered and hectic urban context in the modern age, meaning that architecture is continuously developing vertically, in high-rise buildings. The main point in this research will be the abandoned gap in connecting the internal functions and external appearance. This is another main point which cannot be ignored in designing high rises, which ideally contain both internal and external perceptive aesthetics. The scope of this research will cover three aspects: Function, Perception, and Proportion. Therefore, the work flow of this design tool will be a multi-directional interrelationship between these three steps: 1) internal function and external form generation by various types of constraints, 2) internal function and external form inspection, and 3) internal function and external form modification by the users.

summary Designers; architects and artists in general always proceed with one crucial goal in their mind when they design: to be able to materialize the scheme in their mind. There are some tools that can help designers to test their design to see if it will be successfully constructed or functioned as close as possible as the way they imagined or expected; visual simulation models in digital environments of the designs are such important tools for architectural design process, but these models does not provide enough data to determine the design’s applicability. Therefore, the need of a tool that would work with the designer in order to determine the possibility of whether the design could be built or not as the way designer imagined, is vital.

title Energy Puppet: An Ambient Awareness Interface for Home Energy Consumption
source Digital proceedings of the 7th International Workshop on Social Intelligence Design (SID 2008), School of Architecture, Universidad de Puerto Rico, San Juan, Puerto Rico.
summary The Energy Puppet is an ambient display device that provides peripheral awareness of energy consumption for individual home appliances. The display produces different “pet-like” behavioral reactions according to energy use patterns of the appliances to give homeowners an indication of their energy consumption status. The puppet would raise its “arms” in victory to display normal consumption rate, or its “eyes” would change color to red and “roar” to warn the homeowners when the specific appliance reaches dangerously high consumption rates. The assumption is that the awareness of energy consumption could affect how people consume and control energy use in their households. This paper describes the usage scenarios and the design and implementation of Energy Puppet and discusses future research directions.

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.

summary In this paper we present the results of a comprehensive literature survey on the development of collaborative design. We reviewed 324 papers on collaborative design, taken from various sources (conferences, journals, and PhD-theses). We grouped the papers based on common themes, and in that way derived a classification of themes through the last 25 years (1983-2008). Each category is described, its development, and key publications are identified.

summary This work invests on delimitation of a Geometric Modeling study program directed to students at the initial stages of Architecture. It is considered that the studies promote a qualified control of the form based on recognition of parameters which define it, moreover it also allows the enlargement of the students geometric vocabulary, important to the architectural design activities. In this way, the program advances on the appropriation of new concepts which surround the investigations on architectural design processes, such as the concept of shape grammar. Observing analysis and architectural composition practices based on such concept, contents of geometric modeling which are already being used in the context of post-graduation are identified to be transposed to the graduation context, along with the initial teaching practices of architectural design. The results refer to making the didactic material available, these materials have the objective of building references for the development of design practice which explore the reflection about the processes of creation and composition of architectural form in their geometric aspects.
