summary	We present a simulation platform to evaluate procedurally generated 3d city models with a set of agents representing urban street actors and pedestrians towards greenhouse gas emissions from transportation. Our aim is to give architects and urban planners an empiric tool to analyze, predict and quantify traffic fluctuations over time, and define the number of occupants, individual traffic and public transport in a city. In this project we show that the allocation of functions within a city is an important factor for the appearanceof traffic. The occupant’s decisions where they want to go are defined by the allocation of functions – and the distance defines the mode of transportation. We simulate the decision processes and gain information about the path, the mode of transportation, and the emissions they produce, and individual experiences like stress and effort. The autonomous driving cars are equipped with an acceleration based emission model allowing us to evaluate the inpact of jammed streets on the emission of cars.

summary	Urban spatial models are important to many professions, and they can be used in a wide range of urban decision - making applications. This paper describes a methodology for automatic generation of an urban spatial model from a GIS source. The methodology uses a Voronoi polygon - based method in order to split the urban space. After partitioning the GIS, functional characteristics are used to generate zones of interest at each Voronoi polygon. The paper also presents examples of applications of the model: a two dimensional model used for microsimulation of traffic, and a three - dimensional model used for simulation of air pollution.

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	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	Computational fluid dynamics for efficient urban design
source	Proceedings of the 15th International Conference on Computer Aided Architectural Design Research in Asia / Hong Kong 7-10 April 2010, pp. 357-366
doi	https://doi.org/10.52842/conf.caadria.2010.357
summary	Computational fluid dynamics (CFD) is a method of solving and analysing problems that involved fluid flows. In the field of architecture, urban design and urban planning, CFD is useful for the analysis of ventilation and airflow in the built environment, especially in very dense cities. This paper will look into the possibility of making CFD more accessible to the general design and planning field. A simulation is done on a urban design proposal to quickly see how air flow behaves around it. From there, it looks into the future where technology will make CFD simulation more easily adopted and the possibilities of integrating the ventilation analysis with other environmental analysis results into the urban design arena.

summary	This study covers daylighting performance analysis of inner spaces in two different urban occupation configurations through computational simulation. The scenarios are based on an urban patch of Florianópolis city, with an area of 38,900 square meters. The scenarios were built by CityZoom computer code. The daylighting simulation analyses were performed by Apolux code. The daylighting availability in urban scenario was analyzed through the Preferable Sky Window parameter and obstruction mask. According to this work methodology, guidelines can be developed restricting building height and spacing in order to provide minimum standards of daylight availability.

summary	In this paper, we discuss the different applications of virtual city and environment models within different frameworks and try to reveal their important qualities in relation with their approaches for creating prospective urban developments. Certain uses of urban models and technologies are examined through seven critical cases with a focus on (what) is being modeled, place (where), actors (who), date (when), objectives (why) and approaches (how) adopted for design and development. In the elaboration part, we evaluate and comparatively discuss the interrelated conditions or circumstances that form the setting for these models. In conclusion, a new understanding of Geographical Virtual Environments is reviewed and the critical questions that can determine the future prospects are addressed.

summary	Spurring new and innovative building design will be critical to the urban energy and economic future of the nation. The operation of completed buildings account for 48% of the nation’s annual greenhouse gas emissions, and 76% of all electricity generated by U.S. power plants goes to supply the building sector. Therefore developing and applying new and innovative sustainable building design will have a measurable impact on the environment. Recent studies show sustainable building design is closely linked to system integration, where various components of a building work in confluence to produce synergetic benefits. As a result, a critical component of sustainable design involves a clear understanding of building systems operation, interaction, and the selection parameters. A consideration of suitable building systems, gauging their interaction, and proposing well integrated systems can lead to producing efficient models of sustainable buildings with minimal impact on the environment. The following paper outlines the progress on a project entitled “Building Literacy: the Integration of Building Technology and Design in Architectural Education.” The project develops a digital tool for teaching/learning architectural technology from an integrated systems perspective. The project attempts to immerse students in a simulated environment that is based on the real life practice of architecture. The project accomplishes this by harnessing the capabilities of simulation and dynamic modeling programs, as well as the state of art graphic media, to create compelling and rewarding reasons for students’ engagement in the lear ning process. The project involves a multidisciplinary team of faculty from Florida International University, University at Buffalo the State University of New York, and Iowa State University and is funded by the US Department of Education for the period of 2007-2011.

summary	The following paper deals with a performance-driven morphogenetic design task to improve the conditions of room acoustics, using as a case study the material laboratory of the School of Architecture at Federico Santa Maria University of Technology. Combining contemporary Parametric Modeling techniques and a Performance- Based approach, an automatic generative system was produced. This system generated a modular acoustic ceiling based on Helmholtz Resonators. To satisfy sound absorption requirements, acoustic knowledge was embedded within the system. It iterates through a series of design sub-tasks from Acoustic Simulation to Digital Fabrication, searching for a suitable design solution. The internal algorithmic complexity of the design process has been explored through this case study. Although it is focused on an acoustic component, the proposed design methodology can influence other experiences in Parametric Design.

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 ‚Äúbusiness views‚Äù. We propose a 4 steps-method to compose business views. The first step identifies the users‚Äô 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‚Äôs 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.

title	Patterns, heuristics for architectural design support: making use of evolutionary modelling in design
source	Proceedings of the 15th International Conference on Computer Aided Architectural Design Research in Asia / Hong Kong 7-10 April 2010, pp. 283-292
doi	https://doi.org/10.52842/conf.caadria.2010.283
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.

title	(In:)forming Interactive Architectural Systems, Case of the xMAiA Meta-model

doi	https://doi.org/10.52842/conf.acadia.2010.203
summary	This paper positions the domain of interactive architecture (iA) and searches for an appropriate model for structure and processing of information in the design and operation of such architecture. It is shown that there are different approaches to ways in which iA system models can be defined, each with numerous advantages and disadvantages. However, due to complexity of encountered problems, application of such models can be only partially validated by simulation and hence their design is inherently dependent on creation of operational and experiential full-scale prototypes of the systems these models represent. Another observation is the lack of correspondence between existing iA models and other contemporary models of computation for architectural geometry, fabrication and engineering. A meta-model for extensible multi-agent interactive architecture (xMAiA) is consequently proposed as a remedy to this situation. xMAiA meta-model is aimed to provide an open framework for integrated evolution, development and operation of interactive architectural systems. It delivers an extensible platform, in which diverse, project-specific models and approaches can be implemented, tested, and further evolved. Such a platform has the potential to empower agile development and operation of interactive architectural ecologies, as well as to substantially facilitate integration of creative design and experiential prototyping from day-1 of project design and development cycle. An example application conforming to the xMAiA meta-model is consequently presented and illustrated with a case study project performed in the university education context.

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.

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	A design studio and a parallel research project focused on transformable fabric architecture. To facilitate a part of this work, computer based shape generation tools were used to optimize the placement of thin-film photovoltaic cells onto a transformable roof structure. In addition, the tension membrane fabric is rigged in a way that is similar to a sailing boat. The fabric is set into position by winches and cables. The winches are hand-operated so as to lower the overall energy cost. The initial computer models proceeded concurrently with the mockup of small-scale physical prototypes. In addition, the author used an open source programming language to implement a particle spring real time simulation of the fabric shapes. The simulation included a three-dimensional graphical representation of solar insolation and helped to further determine the physical geometry of the project. One of the goals was to evaluate whether larger transformations to the structure as a whole or smaller movements in the fabric would help to optimize the solar insolation benefits. As the examination of potential forms narrowed down to classical saddle shapes, the practical details of rigging the fabric imposed further limitations on its transformable nature. This paper is focused on how modeling with ad hoc tools and especially real-time computer simulation influenced the direction of the work.

title	I think Therefore i-Phone: The influence of Pervasive Media on Collaboration and Multi-Disciplinary Group Work

summary	The study of value and its transfer during the multi-disciplinary process of design is stable fodder for research; an entire issue of Design Studies has been devoted to Values in the Design Process. By scrutinising design meetings Dantec (2009) and Ball (2009) separately examine the mechanisms of value transfer between the agents involved in design (clients, designers, engineers). Dantec suggests this is best understood in terms of requirement, values and narrative; Ball proposes it should be viewed as a combination of "analogical reasoning" and "environmental simulation". If we look at Vitruvius and his primary architectural manual (Pollio 1960) we find values‚Äîin the form of firmitas, utilitas and venustas‚Äîembedded in this early codification of architectural practice. However, as much current research is restricted to design practice what occurs when value frameworks move between domains of cultural activity (such as design to construction and vice-versa) is not privileged with a comparably sizable body of research. This paper is concerned with the ongoing usage of pervasive media and cellular phones within communications and value transfer across the disciplinary threshold of design and construction. Through participation in a building project we analyse the subtleties of interaction between analogue communication such as sketches and digitally sponsored communication such as e-mail and mobile phone usage. Analysing the communications between the designer and builder during construction suggests it is also a creative process and the distinctions between design and construction processes are complex and often blurred. This work provides an observational basis for understanding mobile computing as a dynamic ‚Äòtuning‚Äô device‚Äîas hypothesized by Richard Coyne (2010)‚Äîthat ameliorates the brittleness of communication between different disciplines. A follow up study deploys ‚Äòdigital fieldnotes‚Äô (dfn) a bespoke iPhone application designed to test further suppositions regarding the influence exerted upon group working by mobile computing. Within collaboration individual communiqu_©s have different levels of importance depending on the specific topic of discussion and the contributing participant. This project furthers the earlier study; expanding upon what mobile computing is and enabling us to infer how these emergent devices affect collaboration. Findings from these two investigations suggest that the synchronous and asynchronous clamour of analogue and digital tools that surround design and construction are not exclusively inefficiencies or disruptions to be expunged. Observational evidence suggests they may provide contingency and continue to have value attending to the relationship between static components‚Äîand the avoidance of failure‚Äîwithin a complex system such as design and construction.

title	Supporting Collective Intelligence for Design in Virtual Worlds: A Case Study of the Lego Universe
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. 637-652.
summary	Virtual worlds are multi-faceted technologies. Facets of virtual worlds include graphical simulation tools, communication, design and modelling tools, artificial intelligence, network structure, persistent object-oriented infrastructure, economy, governance and user presence and interaction. Recent studies (Merrick et al., 2010) and applications (Rosenman et al., 2006; Maher et al., 2006) have shown that the combination of design, modelling and communication tools, and artificial intelligence in virtual worlds makes them suitable platforms for supporting collaborative design, including human-human collaboration and human-computer co-creativity. Virtual worlds are also coming to be recognised as a platform for collective intelligence (Levy, 1997), a form of group intelligence that emerges from collaboration and competition among large numbers of individuals. Because of the close relationship between design, communication and virtual world technologies, there appears a strong possibility of using virtual worlds to harness collective intelligence for supporting upcoming ‚Äúdesign challenges on a much larger scale as we become an increasingly global and technological society‚Äù (Maher et al, 2010), beyond the current support for small-scale collaborative design teams. Collaborative design is relatively well studied and is characterised by small-scale, carefully structured design teams, usually comprising design professionals with a good understanding of the design task at hand. All team members are generally motivated and have the skills required to structure the shared solution space and to complete the design task. In contrast, collective design (Maher et al, 2010) is characterised by a very large number of participants ranging from professional designers to design novices, who may need to be motivated to participate, whose contributions may not be directly utilised for design purposes, and who may need to learn some or all of the skills required to complete the task. Thus the facets of virtual worlds required to support collective design differ from those required to support collaborative design. Specifically, in addition to design, communication and artificial intelligence tools, various interpretive, mapping and educational tools together with appropriate motivational and reward systems may be required to inform, teach and motivate virtual world users to contribute and direct their inputs to desired design purposes. Many of these world facets are well understood by computer game developers, as level systems, quests or plot and achievement/reward systems. This suggests the possibility of drawing on or adapting computer gaming technologies as a basis for harnessing collective intelligence in design. Existing virtual worlds that permit open-ended design ‚Äì such as Second Life and There ‚Äì are not specifically game worlds as they do not have extensive level, quest and reward systems in the same way as game worlds like World of Warcraft or Ultima Online. As such, while Second Life and There demonstrate emergent design, they do not have the game-specific facets that focus users towards solving specific problems required for harnessing collective intelligence. However, a new massively multiplayer virtual world is soon to be released that combines open-ended design tools with levels, quests and achievement systems. This world is called Lego Universe (www.legouniverse.com). This paper presents technology spaces for the facets of virtual worlds that can contribute to the support of collective intelligence in design, including design and modelling tools, communication tools, artificial intelligence, level system, motivation, governance and other related facets. We discuss how these facets support the design, communication, motivational and educational requirements of collective intelligence applications. The paper concludes with a case study of Lego Universe, with reference to the technology spaces defined above. We evaluate the potential of this or similar tools to move design beyond the individual and small-scale design teams to harness large-scale collective intelligence. We also consider the types of design tasks that might best be addressed in this manner.
