summary The paper proposes Parametric Systems Modeling (PSM) as a tool for building and city planning. The outlined method is based on the Systems Modeling Language (SysML) and is intended for design, dimensioning, and optimization of buildings and cities as systems. The approach exceeds the geometric approach, considers additional information from physics, technology, as well as biology, and provides a basis for multidisciplinary analyses and simulations. Its application aims at the exploration of innovative sustainable design solutions at system level. The proposal of an innovative buildinggreenhouse-city system serves to illustrate the approach. Features of this system are closed water cycles, renewable energy use, thermo-chemical energy storage and transport of energy for heating and cooling purposes on the base of desiccants, as well as recycling of CO2 , accumulation of biomass and related soil improvement.

summary The growing demand for sustainable architectural design motivates the integration of BIM technologies and novel design processes into architectural education. This paper presents the results from a set of educational case studies for the incorporation of BIM-based daylighting simulations and analyses into the design studio. With a carefully devised studio setting and the participation of interdisciplinary consultants, the experimental case studies simulated an integrated design process based on rapid information exchange and collaborative decision making. The implemented method enables students to use BIM models and daylighting simulations as significant sources of design information for performance-based architectural design.

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.

title Towards Changeability

summary Many buildings around the world have undergone successive changes over their life cycles. Regardless of the type or size of a building there are usually requirements for change due to several unanticipated forces and emerging uncertainties that act upon them. These changes might be in the building’s spatial, structural or service systems. This can be due to changes in the needs of occupants, the market demand or technological advances. Although buildings undergo change, current design practice does not address this and buildings are still designed as if they will remain static. This paper proposes an Adaptable Buildings Design (ABD) Framework to address the issue of adaptability in building design. Using this methodology uncertainties and future changes are first identified. To increase the building’s longevity, flexibility options are embedded and design rules are formulated to trigger these options when necessary. The value of adaptability is then assessed by implementing several simulations using Real Options Analysis (ROA). To demonstrate the approach, the ABD is applied to a multi-use commercial building case study. Flexibility is embedded in the building’s design across several systems allowing it to change and evolve over time based on a set of design rules. The buildings adaptability is then assessed using ROA. Positive results demonstrate the strength of the proposed methodology in addressing future change and uncertaintie.

title Integrated Design and Building System for the Provision of Customized Housing: the Case of Post-Earthquake Haiti
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. 247-264.
summary The paper proposes integrated design and building systems for the provision of sustainable customized housing. It advances previous work by applying a methodology to generate these systems from vernacular precedents. The methodology is based on the use of shape grammars to derive and encode a contemporary system from the precedents. The combined set of rules can be applied to generate housing solutions tailored to specific user and site contexts. The provision of housing to shelter the population affected by the 2010 Haiti earthquake illustrates the application of the methodology. A computer implementation is currently under development in C# using the BIM platform provided by Revit. The world experiences a sharp increase in population and a strong urbanization process. These phenomena call for the development of effective means to solve the resulting housing deficit. The response of the informal sector to the problem, which relies mainly on handcrafted processes, has resulted in an increase of urban slums in many of the big cities, which lack sanitary and spatial conditions. The formal sector has produced monotonous environments based on the idea of mass production that one size fits all, which fails to meet individual and cultural needs. We propose an alternative approach in which mass customization is used to produce planed environments that possess qualities found in historical settlements. Mass customization, a new paradigm emerging due to the technological developments of the last decades, combines the economy of scale of mass production and the aesthetics and functional qualities of customization. Mass customization of housing is defined as the provision of houses that respond to the context in which they are built. The conceptual model for the mass customization of housing used departs from the idea of a housing type, which is the combined result of three systems (Habraken, 1988) -- spatial, building system, and stylistic -- and it includes a design system, a production system, and a computer system (Duarte, 2001). In previous work, this conceptual model was tested by developing a computer system for existing design and building systems (Benr__s and Duarte, 2009). The current work advances it by developing new and original design, building, and computer systems for a particular context. The urgent need to build fast in the aftermath of catastrophes quite often overrides any cultural concerns. As a result, the shelters provided in such circumstances are indistinct and impersonal. However, taking individual and cultural aspects into account might lead to a better identification of the population with their new environment, thereby minimizing the rupture caused in their lives. As the methodology to develop new housing systems is based on the idea of architectural precedents, choosing existing vernacular housing as a precedent permits the incorporation of cultural aspects and facilitates an identification of people with the new housing. In the Haiti case study, we chose as a precedent a housetype called “gingerbread houses”, which includes a wide range of houses from wealthy to very humble ones. Although the proposed design system was inspired by these houses, it was decided to adopt a contemporary take. The methodology to devise the new type was based on two ideas: precedents and transformations in design. In architecture, the use of precedents provides designers with typical solutions for particular problems and it constitutes a departing point for a new design. In our case, the precedent is an existing housetype. It has been shown (Duarte, 2001) that a particular housetype can be encoded by a shape grammar (Stiny, 1980) forming a design system. Studies in shape grammars have shown that the evolution of one style into another can be described as the transformation of one shape grammar into another (Knight, 1994). The used methodology departs takes off from these ideas and it comprises the following steps (Duarte, 2008): (1) Selection of precedents, (2) Derivation of an archetype; (3) Listing of rules; (4) Derivation of designs; (5) Cataloguing of solutions; (6) Derivation of tailored solution.

title Unicamp 2030: A plan for increasing a university campus in a sustainable way and an example of integrated use of CAAD simulation and computational design strategies
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. 279-286
summary The state university of Campinas, Unicamp, is a public university in upstate São Paulo, Brazil, ranked the second best in the country. It was founded in 1966, and its main campus started to be built in 1967, in the suburbs of Campinas, nowadays a two-million people city. The area of the campus is almost 3 million square meters (300 hectares), with a total built area of 522.000 m2 and a population of 40 thousand people - 30 thousand students, 2 thousand faculty members and almost 8 thousand staff members. The campus’ gross population density is 133 people per hectare. Less than 6% of the total campus area is presently occupied. The design of Unicamp's campus is based on concepts that were typical of the modern movement, with reminiscences of corbusian urbanism, in which preference is given to cars and buildings are spread apart on the territory, with little concern to the circulation of pedestrians. The standard building type that has been built on campus since the 1970's is based on non-recyclable materials, and has a poor thermal performance. Unicamp is expected to double its number of students by the year 2030. The campus density is thus expected to grow from 600 people per hectare to almost 1,000 people per hectare. The need to construct new buildings is seen as an opportunity to correct certain characteristics of the campus that are now seen as mistakes, according to sustainability principles. This paper describes a set of proposals targeting the increase of the campus' density in a sustainable way. The plan also aims at increasing the quality of life on campus and diminishing its impact on the environment. The main targets are: - Reducing the average temperature by 2oC; - Reducing the average displacement time by 15 minutes; - Increasing the campus' density by 100%; - Reducing the CO2 emissions by 50%. // In order to achieve these goals, the following actions have been proposed: Developing a new standard building for the university, incorporating sustainability issues, such as the use of renewable and/or recyclable materials, the installation of rainwater storage tanks, the use of natural ventilation for cooling, sitting the buildings in such a way to decrease thermal gain, and other issues that are required for sustainable buildings' international certifications. To assess the performance of the new standard building, different simulation software were used, such as CFD for checking ventilation, light simulation software to assess energy consumption, and so on. 1. Filling up under-utilized urban areas in the campus with new buildings, to make better use of unused infrastructure and decrease the distance between buildings. 2. Proposing new bicycle paths in and outside campus, and proposing changes in the existing bicycle path to improve its safety. 3. Developing a landscape design plan that aims at creating shaded pedestrian and bicycle passageways.

title A Computational Medium for the Conceptual Design of Mix-Use Projects
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. 109-116
summary Mix use development is receiving wide attention for its unique sustainable benefits. Nevertheless, the planning and designing of successful mixed use projects in today's environment is a complex matrix of skill sets and necessary collaborations between various stakeholders and design professionals. From a design point of view, architects are required to manage and coordinate large information sets, which are many time at odds with one another. The expansive space of knowledge and information is at its best vague and substantially ill-structured. A situation that continues to overburden architects mental and intellectual ability to understand, address and communicate the design issue. In the face of this complex condition, designers are gravitating towards information modeling to manage and organize the expansive data. However, is becoming increasingly evident that current building information modeling applications are less suited for early design activity due to their interrupted and rigid workflows. Against this background, this paper presents a theoretical framework for a computational medium to support the designer during early phases of exploring and investigating design alternatives for mix-use projects. The focus is on the conjecture between programming and conceptual design phase; when uncertainty and ambiguity as at its maximum, and the absence of computational support continues to be the norm. It must be noted however, the aim of the medium is not to formulate or automate design answers. Rather, to support designers by augmenting and enhancing their ability to interpret, understand, and communicate the diverse and multi-faceted design issue. In literature on interpretation, Hans-Georg Gadamer explains that understanding is contingent on an act of construction. To understand something is to construct it. In light of this explanation. To help designers understand the design issue, is to help them construct it. To this end, the computational medium discussed in this paper is conceived to model (construct) the mix-use architectural program. In effect, turning it into a dynamic and interactive information model in the form of a graph (network). This is an important development because it will enable an entirely new level of interaction between the designer and the design-problem. It will allow the designer to gather, view, query and repurpose the information in novel ways. It will offer the designer a new context to foster knowledge and understanding about the ill-structured and vague design issue. Additionally, the medium would serve well to communicate and share knowledge between the various stakeholders and design professionals. Central to the discussion are two questions: First, how can architects model the design program using a graph? Second, what is the nature of the proposed computational medium; namely, its components and defining properties?

summary We need to face challenging needs for the planning of sustainable future cities. New methods in urban simulation enhance significantly the early urban design phase. However, these promising methods will only be sustainable if they consider stakeholder participation from the very beginning. Therefore we propose a conceptual framework for the formulation of stakeholder requirements, which enables the iterative modification of an urban model inside participatory workshops. A special emphasis concentrates on environmental, social and economical factors. The requirements posed by the stakeholders are instantly transferred into urban design patterns. Each single pattern stands for a solution for a specific problem that is integrated and visualized in a procedural model. Our goal is to create a participatory process that takes advantages by the use of comprehensive urban design patterns. The results are integrated within an interactive procedural model that communicate the most important guidelines for the planning of sustainable future cities.

summary The concept maps built and shared on the internet through the CmapTools software resources were used in this exploratory study to follow and analyze the process of collaborative design in public school learning situations. The samples, taken from a Brazilian architectural graduate public school, were maps built in housing design projects developed in a digital environment. A constructivist approach supports the learning method in the use of the net environment for collaborative design of sustainable social housing. This is the base for further development of alternative methodological - theoretical approaches in the context of teaching sustainable design.

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.

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.

title Using Case-Based Reasoning to Aid Sustainable Design
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. 241-246
summary Since so far there exists only one planet, sustainable design is considered the (ethical) future in all fields of design. Although both architecture and construction are being considered major emitters of green house gases, a wise design not only can lead to minimizing this impact but it can also lead to restoring and regenerating the environment to a sustainable state. This paper presents an on-going research that aims at simplifying the elements and facilitating the process of sustainable design by using case-based reasoning. This is achieved through learning from past experiences; both good and bad ones, by providing a database application with a process-friendly interface which divides the main pillars of sustainable design into categories. Each building contains different stories related to different sustainable related issues. Each story can be repeated in /linked to many buildings. By providing designers with those past experiences, it is believed that deeper-studied designs can be more easily developed. Also a deeper analysis and understanding can be further implemented and produced with less effort for experienced and non-experienced architects in sustainable design. This would also decrease the consumption of time during the design process and encourage even more designers to integrate the sustainability concept into more designs. This research discusses the influence of sustainable design within the architectural domain, and suggests a computer application that aids architects during the preliminary design processes.

summary While patterns have a spotty history in architecture, their definitions and uses in other fields offer new possibilities for design. This paper examines those definitions and uses—including theories put forward by architectural theorist, Christopher Alexander; art educator, Gyorgy Kepes; chemist, Ilya Prigogine; and anthropologist, Gregory Bateson. Of particular interest is the shift from eternal, essential, universal, and fundamental patterns to fleeting, superficial, specific, and incidental versions. While endemic to many contemporary architectural practices, this multifaceted view of patterns was anticipated by Bateson, who saw them as agents of evolution and learning. His desire to combine redundancy and noise offers architects new ways to understand patterns and use them to link form and information, matter and thought.

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.

title Understanding Pre-Construction Simulation Activities to Adapt Visualization in 4D CAD Collaborative Tools

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 proposes the use of parametric design software, which is generally used for real-time analysis and evaluation of architectural design variants, to create a new production immanent design tool for robot milling. Robotic constraints are integrated in the data flow of the parametric model for calculating, visualizing and simulating robot milling toolpaths. As a result of the design process, a physical model together with a milling robot control data file is generated.

title Open-source, parametric architecture to propagate hyper-dense, sustainable urban communities: parametric urban dwellings for the experience economy
source Proceedings of the 15th International Conference on Computer Aided Architectural Design Research in Asia / Hong Kong 7-10 April 2010, pp. 443-452

summary Rapid developments in societal, technological, and natural systems suggest profound changes ahead if research in panarchical systems (Holling, 2001) is to be believed. Panarchy suggests that systems, both natural and man-made, rise to the point of vulnerability then fail due to disruptive forces in a process of ‘creative destruction.’ This sequence allows for radical, and often unpredictable, renewal. Pressing sustainability concerns, burgeoning urban growth, and emergent ‘green manufacturing’ laws, suggest that future urban dwellings are headed toward Gladwell’s ‘tipping point’ (2002). Hyper-dense, sustainable, urban communities that employ open-source standards, parametric software, and web-based configurators are the new frontier for venerable visions. Open-source standards will permit the design, manufacture, and sale of highly diverse, inter-operable components to create compact urban living environments that are technologically sophisticated, sustainable, and mobile. These mass-customised dwellings, akin to branded consumer goods, will address previous shortcomings for prefabricated, mobile dwellings by stimulating consumer desire in ways that extend the arguments of both Joseph Pine (1992) and Anna Klingman (2007). Arguments presented by authors Makimoto and Manners (1997) – which assert that the adoption of digital and mobile technologies will create large-scale societal shifts – will be extended with several solutions proposed.

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.

summary A new housing complex on the Campus of the University of Patras, Greece, is expected to serve as a test-bed for experimentation with a parametric design process that integrates significant climatic data. To optimize the environmental performance of the proposed housing complex a parametric design algorithm has been developed. The algorithm links the weather data in the area with the site topography and the basic geometric features of the buildings on the site. To explore the interaction of the building features with the prevailing winds in the area and the solar exposure throughout the year various software applications, including computational fluid dynamics (CFD) simulations, have been utilized. The inclusion of wind data in the algorithm renders it particularly effective. The developed parametric process has been useful during the early design phase when studies on various patterns for arranging the buildings on the site were conducted. The parametric process has facilitated the configuration of the typical building block as well.
