title	A Hydrid Learning Environment: On the subject of design-thinking for non-design students.
source	SIGraDi 2011 [Proceedings of the 15th Iberoamerican Congress of Digital Graphics] Argentina - Santa Fe 16-18 November 2011, pp. 424-427
summary	This paper describes the implementation of a hybrid learning environment (HLE) through the creation, deployment and administration of a large-enrollment course on the subject of Design Thinking. The challenge illustrated by this on-going case study is the one of meeting the learning objectives for a population of novice learners from heterogeneous background through a creative articulation of state-of-the-art instructional technologies. As an additional challenge, given current financial constraints in higher education, the implementation had to address limited funding in the development of the learning environment, the instrumentation provided by the students, and its delivery to large groups of students.

summary	The paper describes and discusses a generic approach for generative design by Turing Machines operating on a three-dimensionally folded surface. It is part of an on going research on concurrent cooperative design processes in architecture. During the development of systems for simplified generic interaction in spatial design, it turned out that the basic operations are applicable to be processed by non-sophisticated automata. If the spatial configuration is interpreted as the medium for an ordinary state machine, the whole system adds up to a kind of Turing Machine. Since 2D-Turing Machines are often referred to as “turmites”, and the proposed system is based on a yet three-dimensional folded, but still twodimensional surface - the automaton will be called “Turmitect”.

title	Analyzing the Ventilation Performance of Tropical High Density Residential Precincts using Computational Fluid Dynamics
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. 351-366.
summary	Major cities in the world are getting bigger as they continue to grow to cater for more population increase. These cities normally forced the urban planning to go high density. In the tropical context, high density cities like Singapore and Hong Kong do not have the luxury of space to go low rise and compact. These cities have to build to the floor area ratio of 4 and above to cater for the population. Their only solution is to go up, as high as possible, to the extent that the natural wind flow pattern will be altered, which brings environmental impact to the people. This is generally not good since wind flow helps to maintain the thermal comfort of the people as heat and pollutants are being channeled out of the city to avoid Urban Heat Island effect. In the tropical context, wind flow is crucial to maintain people‚Äôs comfort as the temperature is generally very high from the exposure of the sun for the entire year. Studies have shown that wind flow plays the most significant part in maintaining human comfort despite exposing to direct sunlight in the tropics. Therefore, wind flow analysis is extremely crucial to make the design sustainable and energy efficient, as people will not have to depend on mechanical ventilation to compensate for the lack of wind flow. Computational Fluid Dynamics (CFD) has always been used in the field of architecture, urban design and urban planning to understand the patterns of wind flow through the built environment apart from wind tunnel tests. The availability of more powerful hardware for the mainstream computer users as well as the lowering costs of these computers made CFD more possible to be adopted in the design world today. This also means using CFD in the design process, especially to analyze the impact of the design to the current site conditions and annual wind patterns will help the new design to be more responsive to the site. The interest of this paper is to analyze the high density typologies to see how well they respond to the local wind flow pattern. A typology is considered acceptable when the wind flow going through the site is still maintaining acceptable wind speed. This means it does not block off the wind and create stagnant spaces. Different designs generate different typologies which will respond differently to the wind pattern. The study aims at comparing the local high density typologies in terms of their response to the wind. Changes to a typology can be explored too to see if the performance will be different. For a typology which is considered a total failure in terms of response to wind, it may improve its performance if the orientation is altered. The CFD software can also parametrically respond to the changes of the typologies‚Äô dimensions. This is helpful to see how much more a typology can still be performing well before failure by increasing the floor area index. The easiest way to do this is to pump up the building height. In conclusion, designing in response to wind is extremely important as it is more sustainable and responsive to Urban Heat Island effect. A design which responds well to the wind patterns will help save cost of cooling load and fan expenditure. The people will also be more willing to use the outdoor spaces which will as a whole generate more vibrant city spaces. As a result, a high density city with huge population count can still enjoy good thermal comfort if the general urban planning and design respond well to wind.

title	A Computer Aided Design Model for Climate Responsive Dwelling Roof
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. 315-332.
summary	Computer-Aided Design models have generated new possibilities in the sustainable design of buildings. Computer models assisting different aspects of architectural design have been developed and used for several decades. A review of contributions of computing to architectural design is given by Gero. Most of the conventional simulation computer programs do not actively support design development and optimization, specially at the formative design stages. It is well established that most decisions that affect comfort and building energy use occur during the formative design stages of the project. Furthermore, the efforts required to implement those decisions at the beginning of the design process are small compared to the effort that would be necessary later on in the design process. Therefore, if sustainable design issues are going to receive an appropriate level of consideration at the beginning of the design process, they must be presented in a way which is useful to the architect and fits with other things the architect is considering at that time. Design is seen as a problem-solving process of searching through a space of design solutions. The process of finding a solution to a design problem involves, identifying one or more objectives, making design decisions based on the objectives, predicting and evaluating the performance to find the acceptable decisions. Each of these activities can be performed inside or outside the formal model. In designing a roof, an architect or building designer has to make many decisions on the materials. The arrangement of these materials determines the aesthetic appearance of the roof and the house. Other considerations that affect the choice of roofing materials are thermal performance, rain, fire protection, cost, availability and maintenance. Recyclability of materials, hazardous materials, life-cycle expectancy, solutions, and design options as they relate to the environment also need to be considered. Consequently, the design of roof has become quite a complex and multifaceted problem. The principal need is for a direct design aid which can generate feasible solutions and tradeoff performance in conflicting requirements and prescribe the optimum solution. This paper presents a conceptual Computer Aided Design model for dwelling roof. It is based on generation and optimization paradigms of Computer Aided Design; which is diametrically opposite to conventional simulation. The design of roof (design goal) can be defined in terms of design objective as "control radiant and conduction heat." This objective must be satisfied to achieve the design goal. The performance variables, such as roof ceiling surface temperature or new thermal performance index (TPI*) must acquire values within certain ranges which will satisfy the objective. Given the required inputs, this computer model automatically generates prescriptive quantitative information to design roof to achieve optimum thermal comfort in warm humid tropics. The model first generates feasible solutions based on the decision rules; next it evaluates the thermal performance of the roof taking into account design variables related to the building‚Äôs roof and finally it applies numerical optimization techniques to automatically determine the optimum design variables, which achieve the best thermal performance. The rational and methodology used to develop the proposed model is outlined and the implementation of model is described with examples for climatic and technological contexts of India and Australia.

title	Change Detection in 3D Parametric Systems: Human-Centered Interfaces for Change Visualization
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. 751-764.
summary	The research on current parametric modeling systems concerns mainly about the underlying computational technology and designs produced; and emphasizes less human factors and design tasks. We observe users being challenged in interacting with these systems regardless of their expertise level. In these systems, user’s attention is divided on system-imposed actions such as tool selection and set-up, managing obscured views, frequent view manipulation, and switching between different types of representations. In essence, control of the system can become more demanding than the design task itself. We argue that this unbalanced emphasis inhibits one of the most important functions of parametric design: agility in exploration of design alternatives by applying frequent user-introduced or system-generated changes on the parametric design models. This compounded by the effect of cognitive limitations such as change blindness and shifts in locus of attention hinders change control and imposes an extra cognitive load in design. In this paper, we made a first step in developing a set of heuristics that is going to present how designers’ change control and detection can be improved. We experimented with three interfaces that control and visualize changes on three different compositions in relation to the designer’s locus of attention: on-model, peripheral and combined views. We measured designers’ performance as the number of changes detected, number of trials, and time required to complete each change detection task. The results support our hypothesis that change blindness significantly slows down and overloads design thinking, and thus should not be ignored. Furthermore, an interesting finding shows that visualizations on the visual periphery can equally support change detection as on-model visualizations, but it is significantly easier and faster to detect changes when they are visualized in both views. These findings can guide us to develop better interfaces in 3D parametric systems.

title	Desarrollando destrezas proyectuales con la asistencia de la Teoría de la Sintaxis del Espacio durante el primer año de los estudios de arquitectura [Developing spatial configuration abilities coupled with the Space Syntax theory for first year architectural studies]
source	SIGraDi 2011 [Proceedings of the 15th Iberoamerican Congress of Digital Graphics] Argentina - Santa Fe 16-18 November 2011, pp. 476-479
summary	The Space Syntax Theory (SST) has been taught at the Bartlett School of Postgraduate Studies at UCL as a tool for architects to explore the relationship between spatial configuration and social form. It has also been used as a design tool to explore and understand, during the design process, possible effects of design ideas on people interaction with space. However the introduction of SST in the first stage of architectural training as a learning resource for developing spatial configuration abilities has not been explored in detail yet. This paper is going to discuss an experience of training architectural students using the SST.

title	Assessing innovation in hybrid designs using shape grammars
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. 545-554
doi	https://doi.org/10.52842/conf.caadria.2011.545
summary	Al-kazzaz et al (2010) described hybrid adaption technique to generate innovative designs from heterogeneous precedents using shape grammars. An evaluation of the degree of innovation in the hybrid designs gave feedback to grammar users before and after applying a rule. Innovation was assessed using variables derived from the internal structure of the grammar such as: the number of antecedents in the corpus having the same rule; the number of rules in a subclass rule set having the same geometry; etc. However, the validity of the innovation assessment was unclear and the use of the feedback measures was not demonstrated. Accordingly, this study aims to verify the credibility of the innovation measures and to identify the independent variables that a user can control to achieve a significant impact on each innovation measure as a dependent variable.

title	Comparing Immersion in Remote and Local Collaborative Ideation Through Sketches: a Case Study
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. 25-40.
summary	Sketches are used in design to support ideation, communication, and collaboration because of their intuitiveness, abstraction, ambiguity and inaccuracy. Design collaboration using freehand sketches is possible through whiteboard software on the Internet. Designers can co-design and share design referents through these tools while adding gestures and expressions using web cams. Freehand sketching using whiteboard software retains the same proportion and scale problems as traditional sketching on paper, but adds digital behaviour (pen tablet display, undo, etc.) and the ability to share sketches in real time with a remote design team. Still, designers are not immersed in their representations. Moreover, such representations can include errors because designers work without reference to real-life perspective views. We developed a system, called the Hybrid Ideation Space (HIS) that allows designers to be immersed in their freehand sketches. The system supports local and remote collaboration, allowing designers to be literally inside their life sized, real time representations, while sharing them with remote collaborators who use another HIS. This paper presents a case study comparing the HIS to conventional whiteboard software (Vyew™) in a context of local and remote design collaboration on two landscape architecture projects. Two multidisciplinary teams worked on the first steps of two ad-hoc projects. The goal was to make an initial observation of the impact of immersion and see if it delivers benefits to collaborative ideation. Two methodological tools supported the study: the Design Flow for the experience that includes the NASA TLX to measure the workload, and the Collaborative Ideation Loop (CI-Loop) for design collaboration.

title	First steps of the augmented design studio: The interconnected Hybrid Ideation Space and the CI Loop
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. 271-280

summary	Professional or school design studios are essential environments for design supporting free exploration of materials and representations, analogue or digital. New technologies have moved into the studio with mixed results. Paradoxically, the use of portable computers, using Internet as collaboration channel, has actually individualized the design work and limited the support to co-creation, reinforcing individual work. The Augmented Design Studio argues for the implementation of hybrid technology, such as the Hybrid Ideation Space (HIS), in the design studio to compensate for the absence of collective local or remote efficient ideation space. This paper presents a case study showing the primary results of distant synchronous and asynchronous design collaboration supported by the interconnected HIS during an ad-hoc project and assessed by the improved Collaborative Ideation Loop (CI Loop) methodology. The HIS was installed in two universities located in different countries. We ran a research protocol in the format of a design charrette where two teams (team a: two architecture students, team b: two industrial design students) participated in the ideation of a bus shelter. This case study shows that teams were able to co-design while they were virtually “teleported” into each other’s representations.

title	From Digital Heritage Documentation to 3D Virtual Reconstruction and Recreation for Heritage Promotion and Reinterpretation: The Case of the iHeritage Project
source	C+++: Computation, Culture, and Context – Proceedings of the 11th International Conference of the Arab Society for Computation in Architecture, Art and Design (ASCAAD), University of Petra, Amman, Jordan [Hybrid Conference] 7-9 November 2023, pp. 7-23.
summary	In the last two decades, the digital age Information and Communication Technologies (ICT) development and concerns combined with rapid technology have permitted the dissemination of different digital applications (including digital documentation, virtual reality (VR), augmented reality (AR), mixed reality (MR), digital gaming, and holograms etc.) oriented toward past, present and future communication using digital three-dimensional audio-visual content. Today, we must acknowledge that 3D virtual 3D reconstruction and recreation has become an established way to build, understand, reinterpret, and promote Cultural Heritage (CH). The virtual 3D reconstruction world and multimedia industry are often considered potential marketing channels for World Heritage Sites (WHS) and heritage tourism. 3D digital/virtual reconstruction merges and embodies subjectivity in one process, playing an attractive role in heritage tourism destinations and creating image experiences, providing the first enjoyable interpretation and information for most audiences. Based on the EU-funded iHERITAGE project ICT Mediterranean platform for the UNESCO CH, this paper attempts to examine some insights into constructing the optimistic image of heritage promotion and tourism in the context of CH as it flows through both physical and virtual spaces to give a glimpse of the future of virtual reconstruction. It illustrates the development of the concepts and practice, challenges and opportunities, advantages and disadvantages, and the negative and the positive sides of the related issues of only 3D digital reconstructions, and some issues concerning the ethics based on the International Chartres and Conventions mainly in the field of scientific visualisation, such as the London Charter (2009) and Seville Principles (2011). Finally, as a practical dimension, it presents some representative examples of 3D digital/virtual reconstruction of characteristic monuments of the WHS of Nabataean Petra in Jordan for the first time.

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
doi	https://doi.org/10.52842/conf.caadria.2011.291
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.

doi	https://doi.org/10.52842/conf.caadria.2011.429
summary	Designers interact with a wide range of design tools, in a variety of ways, in order to support their work. Any attempt to produce digital tools aimed at supporting ideation raises the question of the kind of information considered account and what is appropriate to the needs and expectations of designers. We developed and implemented an assessment method for digitally supported conceptual design based on reflective conversation, flow, cognitive ergonomics and activity theory. Our approach opens up the evaluation spectrum to include parameters beyond performances factors for conceiving new digital design tools. This assessment approach considers user (the designer), action (ideation) and object (the tool) in the ideation process, namely the designer’s experience interrelated to the needs of the task and the characteristics of the tool. In this paper we present the results of several research protocols in which we observed, analyzed and successively acted upon five different stages of the interface of a design tool as it was being developed, the Hybrid Ideation Space (HIS). Taken as a whole, these results suggest the limits and support of designers’ optimal relationship with an ideation interface.

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	Important progress towards the development of a system that enables multi-criteria design optimisation has recently been demonstrated during a research collaboration between Autodesk’s DesignScript development team, the University of Bath and the engineering consultancy Buro Happold. This involved integrating aspects of the Robot Structural Analysis application, aspects of the Ecotect building performance application and a specialist form finding solver called SMART Form (developed by Buro Happold) with DesignScript to create a single computation environment. This environment is intended for the generation and evaluation of building designs against both structural and building performance criteria, with the aim of expediently supporting computational optimisation and decision making processes that integrate across multiple design and engineering disciplines. A framework was developed to enable the integration of modeling environments with analysis and process control, based on the authors’ case studies and experience of applied performance driven design in practice. This more generalised approach (implemented in DesignScript) enables different designers and engineers to selectively configure geometry definition, form finding, analysis and simulation tools in an open-ended system without enforcing any predefined workflows or anticipating specific design strategies and allows for a full range of optimisation and decision making processes to be explored. This system has been demonstrated to practitioners during the Design Modeling Symposium, Berlin in 2011 and feedback from this has suggested further development.
