title Multi-touch - the future of design interaction
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. 557-572.
summary The next major revolution for design is to bring the natural user interaction into design activities. Graphical User Interfaces (GUI) brought a new approach that was more effective compared to their conventional predecessors. In recent years, Natural User Interfaces (NUI) have advanced user experiences and multi-touch and gesture technologies provide new opportunities for a variety of potential uses in design. Much attention has been paid to leverage in the design of interactive interfaces. The mouse input and desktop screen metaphors limit the information sharing for multiple users and also delayed the direct interaction for communication between each other. This paper proposes the innovative method by integrating game engine ‘Unity3D’ with multi-touch tangible interfaces. Unity3D provides a game development tool as part of its application package that has been designed to let users to focus on creating new games. However, it does not limit the usage of area to design additional game scenarios since the benefits of Unity3D is allowing users to build 3D environments with its customizable and easy to use editor, graphical pipelines to openGL (http://unity3d.com/, 2010 ). It creates Virtual Reality (VR) environments which can simulates places in the real world, as well as the virtual environments helping architects and designers to vividly represent their design concepts through 3D visualizations, and interactive media installations in a detailed multi-sensory experience. Stereoscopic displays advanced their spatial ability while solving issues to design e.g. urban spaces. The paper presents how a multi-touch tabletop can be used for these design collaboration and communication tasks. By using natural gestures, designers can now communicate and share their ideas by manipulating the same reference simultaneously using their own input simultaneously. Further studies showed that 3Dl forms are perceived and understood more readily through haptic and proprioceptive perception of tangible representations than through visual representation alone (Gillet et al, 2005). Based on the authors’ framework presented at the last CAADFutures, the benefits of integrating 3D visualization and tactile sensory can be illustrated in this platform (Chen and Wang, 2009), For instance, more than one designer can manipulate the 3D geometry objects on tabletop directly and can communicate successfully their ideas freely without having to waiting for the next person response. It made the work more effective which increases the overall efficiency. Designers can also collect the real-time data by any change they make instantly. The possibilities of Uniy3D make designing very flexible and fun, it is deeply engaging and expressive. Furthermore, the unity3D is revolutionizing the game development industry, its breakthrough development platform for creating highly interactive 3D content on the web (http://unity3d.com/ , 2010) or similar to the interface of modern multimedia devices such as the iPhone, therefore it allows the designers to work remotely in a collaborative way to integrate the design process by using the individual mobile devices while interacting design in a common platform. In design activities, people create an external representation of a domain, often of their own ideas and understanding. This platform helps learners to make their ideas concrete and explicit, and once externalized, subsequently they reflect upon their work how well it sits the real situation. The paper demonstrates how this tabletop innovatively replaces the typical desktop metaphor. In summary, the paper addresses two major issues through samples of collaborative design: firstly presenting aspects of learners’ interactions with physical objects, whereby tangible interfaces enables them constructing expressive representations passively (Marshall, 2007), while focussing on other tasks; and secondly showing how this novel design tool allows designers to actively create constructions that might not be possible with conventional media.

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 Assessing the Use of Advanced Daylight Simulation Modelling Tools in Enhancing the Student Learning Experience
source Digital Crafting [7th International Conference Proceedings of the Arab Society for Computer Aided Architectural Design (ASCAAD 2014 / ISBN 978-603-90142-5-6], Jeddah (Kingdom of Saudi Arabia), 31 March - 3 April 2014, pp. 303-313
summary In architecture schools, where the ‘studio culture’ lies at the heart of students’ learning, taught courses, particularly technology ones, are often seen as secondary or supplementary units. Successful delivery of such courses, where students can act effectively, be motivated and engaged, is a rather demanding task requiring careful planning and the use of various teaching styles. A recent challenge that faces architecture education today, and subsequently influences the way technology courses are being designed, is the growing trend in practice towards environmentally responsive design and the need for graduates with new skills in sustainable construction and urban ecology (HEFCE’s consultation document, 2005). This article presents the role of innovative simulation modelling tools in the enhancement of the student learning experience and professional development. Reference is made to a teaching practice that has recently been applied at Portsmouth School of Architecture in the United Kingdom and piloted at Deakin University in Australia. The work focuses on the structure and delivery of one of the two main technology units in the second year architecture programme that underwent two main phases of revision during the academic years 2009/10 and 2010/11. The article examines the inclusion of advanced daylight simulation modelling tools in the unit programme, and measures the effectiveness of enhancing its delivery as a key component of the curriculum on the student learning experience. A main objective of the work was to explain whether or not the introduction of a simulation modelling component, and the later improvement of its integration with the course programme and assessment, has contributed to a better learning experience and level of engagement. Student feedback and the grade distribution pattern over the last three academic years were collected and analyzed. The analysis of student feedback on the revised modelling component showed a positive influence on the learning experience and level of satisfaction and engagement. An improvement in student performance was also recorded over the last two academic years and following the implementation of new assessment design.

summary The recent developments in digital technologies and contemporary design tools are initiating new approaches of form-finding based on parametric development of multiple geometries with simultaneous consideration of various aspects. This paper focuses on the use of advanced parametric CAD systems and reformulated construction logics to enhance the potential and possibilities of form finding processes. This approach is exemplified through the “Greenhouse Trauttmansdorff project”. The project demonstrates a form finding approach which is based on defined parameters that not only fulfil aesthetic and functional aspects, but simultaneously take structural properties and the resulting sun shading behaviour into account. We will explore within this paper how – next to the functional and contextual building requirements – required illumination levels inside the greenhouse create a feedback loop between the structural system and its cladding system.

summary Building Information Modelling (BIM) is expected to enable efficient collaboration, improved data integrity, distributed and flexible data sharing, intelligent documentation, and high-quality outcome, through enhanced performance analysis, and expedited multi-disciplinary planning and coordination. Despite these apparent benefits, the collaboration across the architecture, engineering and construction (AEC) disciplines is largely based on the exchange of 2D drawings. This paper reports the findings from a research project that aims at developing measures to enhance BIM-based collaboration in the AEC industry. Based on focus group interviews with industry participants and case studies of BIM applications, visualisation was identified as an interactive platform across the design and non-design disciplines. It is argued that visualisation can enhance the motivation for BIM-based collaboration through integration of advanced visualisation techniques such as virtual reality (VR) and augmented reality (AR). An AR interface for a BIM server is also presented and discussed in the paper. AR can open up potential opportunities for exploring alternatives to data representation, organisation and interaction, supporting seamless collaboration in BIM.

summary The authors base their efforts on the assumption that future cities will only be called ‘advanced’ and ‘sustainable’ if they evolve as a shared vision between the city users / dwellers (general public) and urban designers, planners, architects, engineers (experts). For visions to be shared and planning processes to be inclusive the involvement of all (urban) actors is paramount. With the increasing urban complexity and the interrelation of phenomena there is also an increasing demand for updated, advanced and re-thought digital tools that could help in forming and enabling such common urban visions. The paper outlines the agenda and connects our on-going research efforts with the fields deemed most crucial for inclusive-for-all, successful participation that can lead to shared visions of future cities. Standing out in interchangeable order and never-ending cyclic process are: (1) education, (2) communication and (3) collaboration.

title The Sustainable Management of Remote Construction Projects

summary This paper discusses investigates the use of present project management practices and systems by the construction department of the Saudi Electric Company (SEC), Kingdom of Saudi Arabia (KSA). It highlights shortages of the current management practices and systems and how it affects badly the sustainability dimensions of projects such as quality, scope, time and cost. The literature review suggests that Advanced Electronic Management and Communications systems (AEMCS) may help companies in managing remote projects efficiently thus minimizing the travel time, reducing unnecessary project costs and raising the quality of projects. Little research though was done regarding this issue and it found few unique management problems. A field survey was conducted on contractors and SEC’s supervision teams. It revealed that some of the remote project’s management problems however were caused by unprofessional and non standard project management conduct. It also found that traditional systems are very popular whereas advanced electronic systems are of little use. Participants expressed their concerns about the SEC’s present project management practices and their views regarding the implementation of advanced electronic project management systems and its possible impact on projects’ performance and process. The survey’s outcomes indicated that advanced electronic management systems should be tailored to SEC’s present and prospected needs, meanwhile SEC’s present project management methodologies should be adjusted into sustainable management practices. This would guarantee that project management practices will be substantially improved and sustainable objectives of projects are met. The study should motivate the SEC and other companies in KSA to review their present project management practices and systems, investigate the potentiality of advanced electronic systems use in managing remote projects and explore how to embrace sustainability’s dimensions in project management practices.

title Design and Simulation of Textile Building Elements
source CAAD - Cities - Sustainability [5th International Conference Proceedings of the Arab Society for Computer Aided Architectural Design (ASCAAD 2010 / ISBN 978-1-907349-02-7], Fez (Morocco), 19-21 October 2010, pp. 161-170
summary In this paper we examine the use of textile building elements and investigate on their potential scope of application in architecture. Other than commonly used for spanned or tent-like structures we concentrate on the use of textiles for folded, crinkled and procumbent assemblies, as these seem to correspond much better with the textiles´ inherent properties. On closer examination of these properties it becomes obvious that fabric primarily exists in a loose, uneven and irregular physicality that can be adjusted and configured into different states that match specific criteria. That is why fabric is mainly used for covering, protecting or hiding objects, e.g. as apparel for people. Only at a second glance does one recognize that textiles can be used for many other purposes such as collecting, separating, filtering or even healing. Thus, in the first instance of this research we examined customary usages and classified them into different categories that aided us to further develop practical application areas for the architectural domain. Subsequently to the fact that the shape of a textile might alter under the influence of forces, the further focus of this research lied on the appraisal of digital simulation techniques and simulation engines to provide sophisticated instruments for the generation of the associated time-based geometric form of the fabric. External elements that might drive this deformation process such as wind, temperature, precipitation, as well as static and dynamic building components were considered in the simulation process in order to generate visual output of the corresponding shapes. Studies about bipartite materials that can control the deformation process and might lead the textile beyond its primary functionality conclude this work.

summary As issues of sustainability gain traction for architects, methodologies for designing, analyzing, and calibrating design solutions have emerged as essential areas of research and development. A number of approaches have been pursued with regard to embedding data into the design process, most fall into one of two approaches to research. The first approach is to mediate environmental impact at the level of applied technology; the second alters building methods and material construction, generating efficient energy use. However, few approaches deal with the crafting of relationships between information and performance on an architectural level. We will examine an approach focused on understanding how crafting relationships between information and design can move architecture towards achieving sustainability. In developing this approach, we created a data-driven design methodology spanning from design inception to construction. Data-driven models, common in the fields of natural science, offer a method to generate and test a multiplicity of responsive solutions. By contextualizing the solutions generated, we were able design though a set of specific and controlled responses rather than as a singular solution. Information utilization requires a new kind of craft that moves beyond instances into relationships and offers performance sensitive issues in design a focused trajectory. We applied this method to the research and development of a responsive shading structure built in conjunction with a thermal testing lab for two test locations – Austin, Texas (Figure. 1 and 2) and Munich, Germany. The following paper chronicles the design and construction at the Texas site over an academic semester.

summary Architecture is the mediator between the Environment and Humans. Nature maximal performance and minimal resources creations are Humanity inspiration that led us to exceed structural, material, mechanisms, tools, systems and methods boundaries (Oxman, 2010).Nature are the Architect of the most reliable and sustainable systems. Looking into Nature's lessons, this paper presents a Nature-based design methodology conducted during Kine[SIS]tem'17 Shading Systems International Summer School, held by the ISCTE-Instituto Universitário de Lisboa, Portugal, between 19th - 30th June 2017. The methodology encompasses two main stages, one before and other during the Summer School. From a pre-definition of context constrains, a nature based design strategy, to a planning of the manufacture and construction still during the phase of development of the design, conducted the Summer School participants through a defined biomimetic process that achieved the construction of 1:1 scale prototype.

title Parametric Design of the Vela Roof
source CAAD - Cities - Sustainability [5th International Conference Proceedings of the Arab Society for Computer Aided Architectural Design (ASCAAD 2010 / ISBN 978-1-907349-02-7], Fez (Morocco), 19-21 October 2010, pp. 231-240
summary Due to the increased request for representative structures and for spaces to be used independent of the weather conditions, contemporary cities increasingly integrate public covered spaces (shadowed squares and streets, courtyards, historic commercial galleries, etc.) in the urban fibre. Facing the design of large roof structures for semi outdoor spaces is increasingly common for architects and engineers. When focusing on large roofs, aesthetics, structural performance and economics often dominate the design process. However, the current increased emphasis on energy-related aspects generates new challenges. Particularly, the use of renewable energy resources needs to be confronted. In this paper we will address the subject through a case study whose design aimed at integrating performance evaluations in the very early stages of the process. The case study focuses on the so-called “Vela roof”. This roof is part of a larger project currently under construction in Bologna (Italy). The focus of the study concerns the use of on-site renewable climate (energy) resources with special attention given passive reduction of summer overheating and daylight. For these tasks a parametric model was developed to support the decision making process and the paper will present its potential with respect to performance-oriented design during the conceptual design phase of roof structure. The very first conceptual design developed by the architectural office was assumed as a starting point for the inclusion of performance criteria. In the preliminary design of the roof uncomfortable conditions were expected under the whole roof in the summer. Various strategies for improving the thermal comfort were investigated, involving a large set of combined systems. Not all of these will be detailed in this paper. Instead we will focus on the ones directly affected by the geometry of the roof. Those are mainly air flow for cooling and the reduction of solar gain, in combination with their effects on daylight. Their investigation was based on a chain of dependencies to be integrated in the design process. With respect to that, parametric modelling was used. Parametric modelling allows both geometrical entities and their relationships to be represented. These relationships are structured in a hierarchical chain of dependencies, established during the preliminary parameterization process. The independent properties of the model are usually expressed through independent parameters, and their variations generate different configurations of the model. By making use of this potential, three project scales were parametrically explored. At the large scale, parametric variations of the overall shape of the roof were investigated in relation to cooling through ventilation and here the parametric model allowed for the generation of both different configurations of the roof, including its structural morphology and variations of its structural tessellation. At the medium scale, the integration of openable modules was investigated in relation to air extraction for cooling; with respect to this, the parametric model allows exploring openings based on variations of size and distribution. At the small scale, various options were explored for the cladding system, in order to reduce the direct solar gain while still allowing the income of indirect natural light. The parametric model was used to investigate the configuration of self-shading modules and their integration in the structure. Specific emphasis will be given to the small scale. The advantages in design process and the current limits of the parametric modelling approach used here will be discussed in the paper.

summary Innovative technologies that enable more efficient use of energy in the built environment contribute to the effectiveness of green building design, and to sustainable building practices. Digital fabrication can be used to unlock the inherent physical properties of common materials as a means to create solar shades which change shape in response to ambient conditions and user needs in a system which relies on extremely simple mechanical actuation. These conformationally adaptive solar shades take advantage of materials which can be deformed not only to occlude or permit the passage of light, but also to produce optimal angles for the maximization the interception of solar radiation of the surface of the device itself.

summary This paper reports on the computer process to be used in an ongoing research to investigate the effect of architectural parameters of tall buildings on the incorporation of wind turbines. The process combines a generative modeling tool (Grasshopper) and a performance based CFD tool (Virtualwind). The process is demonstrated on three typical tall building plan configurations. The wind speed was simulated at certain locations to demonstrate the ability of tall buildings to enhance the wind speed and thus maximize the energy produced by wind turbines located between twin towers. The process to predict wind power production is lastly listed.

title Understanding Pre-Construction Simulation Activities to Adapt Visualization in 4D CAD Collaborative Tools
source Computer Aided Architectural Design Futures 2011 [Proceedings of the 14th International Conference on Computer Aided Architectural Design Futures / ISBN 9782874561429] Liege (Belgium) 4-8 July 2011, pp. 477-492.
summary Increasing productivity and efficiency is an important issue in the AEC field. This area is mainly characterized by fragmentation, heterogeneous teams with low lifetimes and many uncertainties. 4D CAD is one of the greatest innovations in recent years. It consists in linking a 3D model of the building with the works planning in order to simulate the construction evolution over time. 4D CAD can fill several needs from design to project management through constructivity analysis and tasks planning (Tommelein 2003). The literature shows that several applications have been proposed to improve the 4D CAD use (Chau et al. 2004; Lu et al. 2007; Seok & al. 2009). In addition, studies have shown the real impact of 4D CAD use in construction projects (Staub-French & Khanzode 2007; Dawood & Sika 2007). More recently, Mahalingam et al. (2010) showed that the collaborative use of 4D CAD is particularly useful during the pre-construction phase for comparing the constructability of working methods, for visually identifying conflicts and clashes (overlaps), and as visual tool for practitioners to discuss and to plan project progress. So the advantage of the 4D CAD collaborative use is demonstrated. Moreover, several studies have been conducted both in the scientific community and in the industrial world to improve it (Zhou et al. 2009; Kang et al. 2007). But an important need that remains in collaborative 4D CAD use in construction projects is about the adaptation of visualization to the users business needs. Indeed, construction projects have very specific characteristics (fragmentation, variable team, different roles from one project to another). Moreover, in the AEC field several visualization techniques can represent the same concept and actors choose one or another of these techniques according to their specific needs related to the task they have to perform. For example, the tasks planning may be represented by a Gantt chart or by a PERT network and the building elements can be depicted with a 3D model or a 2D plan. The classical view (3D + Gantt) proposed to all practitioners in the available 4D tools seems therefore not suiting the needs of all. So, our research is based on the hypothesis that adapting the visualization to individual business needs could significantly improve the collaboration. This work relies on previous ones and aim to develop a method 1) to choose the best suited views for performed tasks and 2) to compose adapted multiple views for each actor, that we call “business views”. We propose a 4 steps-method to compose business views. The first step identifies the users’ business needs, defining the individual practices performed by each actor, identifying his business tasks and his information needs. The second step identifies the visualization needs related to the identified business needs. For this purpose, the user’s interactions and visualization tasks are described. This enables choosing the most appropriate visualization techniques for each need (step 3). At this step, it is important to describe the visualization techniques and to be able to compare them. Therefore, we proposed a business view metamodel. The final step (step 4) selects the adapted views, defines the coordination mechanisms and the interaction principles in order to compose coordinated visualizations. A final step consists in a validation work to ensure that the composed views really match to the described business needs. This paper presents the latest version of the method and especially presents our latest works about its first and second steps. These include making more generic the business tasks description in order to be applicable within most of construction projects and enabling to make correspondence with visualization tasks.

summary This paper illustrates responsive systems, which focus on the implementation of multi-objective adaptive design prototypes from sensored environments. The intention of the work is to investigate multi-objective criteria both as a material system and as a processing system by creating prototypes with structural integrity, where the thermal energy flow through the prototype, to be understood as a membrane, can be controlled and the visual transparency altered. The work shows performance based feedback systems and physical prototype models driven by information streaming, screening, and application.

title Flujo energético en las etapas tempranas del proceso de diseño arquitectónico y la importancia de generar aprendizajes significativos [Energy flow in early stages of architectural design process, and the importance of creating meaningful learning]
source SIGraDi 2010_Proceedings of the 14th Congress of the Iberoamerican Society of Digital Graphics, pp. Bogotá, Colombia, November 17-19, 2010, pp. 281-284
summary This proposal seeks to stimulate energy conceptualization in the early stages of architectural design through the visualization of energy conditions as a dialogue in initial design configurations that is based on the integration of two software tools to facilitate meaningful learning. Students today have analytical intelligence that they have acquired through teaching themselves, and this has developed their creativity and their experiential - contextual practice; this permits effective interpretation of symbolic cognition. Digital tools of building, information modeling, and energy analysis can be related to specific features that promote this integrated design learning.
keywords KEY WORDS: performance views, building information modeling, visual and thermal comfort, integrated design learning, efficiency andoptimization.

summary Nowadays, a large set of involved planning parties are heavily demanded with the definition of holistic in kind requirement specifications for urban planning sites – so called future cities. However, the resulting amountof specifications for a specific building project poses a great challenge to designers and planners especially when it comes to include this information into their design proposals for a sustainable urban development. These design performance criteria are traditionally expressed in textual and numerical planning guidelines and which are making it difficult to establish a comprehensive and holistic view onto the domain itself. Therefore we present in this paper a design guide visualization method to overcome this situation for the evaluation of design specification and urban layouts in a qualitative and quantitative manner.

title HYGROSCOPIC CLIMATIC MODULATED BOUNDARIES: A Strategy for Differentiated Performance Using a Natural Circulative and Energy Captive Building Envelope in Hot and Moisture Rich Laden Air Environments
source Perkins+Will Research Journal, Vol 02.01, 41-53
summary The operation and construction of buildings account for almost half of the energy use in the United States. To meet global climate change targets, energy consumption of buildings in the long term must be reduced as well as carbon dioxide emissions. This article explores a theoretical building envelope that generates energy and produces water by drawing water vapor out of the air to deliver new sources of water; it lowers indoor humidity in hot and humid climates. The design in this model considers materiality, surface area and environmental conditions to influence build- ing form. The case in this article considers materials and systems application in the design of the building envelope. The hygroscopic building envelope design strategically senses varying conditions of concentration and density of moisture laden air to provide visual indications of its performance. It is a building skin that emulates biological processes by creating pressure differences and transferring energy in various forms.

summary The research presented in this paper investigates ways of providing better design applications for technologies in the field of Urban Digital Media (UDM). The work takes an emergent approach, evolving a design strategy through the early engagement of stakeholders. The paper discusses research in a design-led creative intersection between media technology, culture and the arts in the built environment. The case study discusses opportunities for the enhancement of a university campus experience, learning culture and community, through the provision of an integrated digital presence within campus architecture and urban spaces. It considers types of information architecture (Manovich, 2001) and designs for use in urban settings to create communication-rich, advanced and interactive designed spaces (Haeusler, 2009). The presented research investigates how to create a strategy for display technologies and networked communications to transform and augment the constructed reality of the built environment, allowing new formats of media activity.

title Patterns, heuristics for architectural design support: making use of evolutionary modelling in design
doi https://doi.org/10.52842/conf.caadria.2010.283
source Proceedings of the 15th International Conference on Computer Aided Architectural Design Research in Asia / Hong Kong 7-10 April 2010, pp. 283-292
summary Software used by architectural and industrial designers has shifted from becoming a tool for drafting, towards use in verification, simulation, project management and remote project sharing. In more advanced models, design parameters for the designed object can be adjusted so that a family of variations can be produced rapidly. With the advances in computer aided design (CAD) technology, design options can now be generated and analyzed in real time. However the use of digital tools to support design as an activity is still at an early stage and has largely been limited in functionality with regard to the design process. To date, major CAD vendors have not developed an integrated tool that is able to leverage specialised design knowledge from various discipline domains (known as expert knowledge systems) as well as to support the creation of design alternatives that satisfy different forms of constraints. We propose that evolutionary computing and machine learning be linked with parametric design techniques in order to monitor a designer’s cognition and intent based on their design history. This will lead to results that impact future work on design support systems which are capable of supporting implicit constraint and problem definition for wicked problems that are difficult to quantify.
