summary	The purpose of this study is the development of a tool by which citizens who are non-specialists can design a regional revitalisation project. Therefore, a 3D CAD / VR (3-dimensional computer-aided design / virtual reality) combination system was developed by using SketchUP Pro, GIMP, and UC-win / Road. This system has the advantages of low cost and easy operation. The utility of the system was verified as a result of applying the developed prototype system in the Super Science High School program for high school students created by the Ministry of Education, Culture, Sports, Science and Technology, Japan. It has been used for two years, since 2007. In addition, the characteristics of the VR made by the non-specialists were considered.

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	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	In the last few years, building renovation has gained an unprecedented relevance in Portugal, yet it is an asymmetric and urban phenomenon for the study of which, in space and in time, traditional statistic tools have limitations. Using computational tools, it is possible to generate maps that correlate building permits georeferenced data and their processing time. Using Lisbon City Hall database of planning applications and georeferenced vector information, two approaches are developed to represent the internal dynamic of renewal of the city between 2010 and 2016. These maps can be useful to improve the accessibility of planning information to citizens.

title	Urban micro-informatics: a test case for high-resolution urban modelling through aggregating public information sources
source	Proceedings of the 15th International Conference on Computer Aided Architectural Design Research in Asia / Hong Kong 7-10 April 2010, pp. 327-336
doi	https://doi.org/10.52842/conf.caadria.2010.327
summary	Our contention is that the city is a rich collection of urban micro-ecologies in continuous formation that include information types outside the traditional boundaries of urban design, city planning, and architecture and their native data fields. This paper discusses working with non-standard urban data types of a highly granular nature, and the analytical possibilities and technical issues associated with their aggregation, through a post professional masters level research studio project run in 2008. Opportunities for novel urban analysis arising from this process are discussed in the context of typical urban planning and analysis systems and locative media practices. This research bought to light specific technical and conceptual issues arising from the combination of processes including sources of data, data collection methods, data formatting, aggregating and visualisation. The range and nature of publicly available information and its value in an urban analysis context is also explored, linking collective information sites such as Pachube, to local environmental analysis and sensor webs. These are discussed in this paper, toward determining the possibilities for novel understandings of the city from a user centric, real-time urban perspective.

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	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.

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.

summary	This study aims to develop the parametric urban model to support Form-based Codes (FBCs) by using Object-Oriented Parametric Modeling (OOPM) and Building Information Modeling (BIM). FBCs have been used to substitute conventional land-use and zoning regulations in the United States. In many cities, FBCs were implemented successfully, but excessive design constraints, difficult code making process, and missing density of FBCs are criticized. As a response to the increasing needs of parametric modeling approaches in the urban design domain, we applied BIM and OOPM techniques in two case studies. We conclude that BIM and OOPM have a great potential to support planning and design processes, and that the parametric urban model allows FBCs to be more flexible, interpretable, and interoperable.

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	Scale and Complexity: Multi-layered, multi-scalar agent networks in time-based urban design

summary	Urban design, perhaps even more than architecture, is a timedependent discipline. With its multi-layered complexities, from individual buildings to entire regions, decisions made at one level, that may not show effect immediately, may prove to have disastrous consequences further down the line. The need to incorporate time-based simulations in urban modeling, and the demand for a means of evaluating the changes have led to explorations with multi-agent systems in computation that allow for decisions to be decentralized. From the first basic rule-based system of Conway’s Game of Life [1] to recent urban simulations developed at institutions like the ETH Zurich [2], or UCL CASA [3], these programs synthesize the various exigencies into complex simulations so that the designer may make informed decisions. It is however not enough to simply use parametrics in urban design. Rules or desires implemented at one scale may not apply to another, while isolating each scalar layer for independent study reverts to the disjunctive and shortsighted practices of past planning decisions. Central to current parametric research in urban design is the need to deal with multiple scales of urbanism with specific intelligence that can then feed back into the collective system: a networked parametric environment. This paper will present the results from a city-generator, developed in Processing by Dino Rossi, Dominik Zausinger and Jeannette Kuo, using multiagent systems that operate interactively at various scales.

title	Urban Space Planning for Sustainable High Density Environment

summary	In this paper we investigate the possibilities of new typologies of urban public space for high density environments. The premise for the project would be that with new high-density typologies, it would be necessary to consider a difference in the nature of urban public spaces rather than a difference in degree from the status quo. From observations of urban patterns that drive collective, hybrid spaces around Asia, relationships between urban attributes are drawn. For this paper we shall focus on the particular case of Linked Hybrid, Beijing, China, as an elevated urban public space. A literature review focuses on reviewing key theories to construct and adopt a rating system to develop an empirical framework to evaluate the case studies and extract the key attributes. These rated attributes are then abstracted in a real-time model that enables user manipulation. The purpose is to create a tool to better observe the effects and evolution of planning decisions for future urban spaces in high density contexts. The preliminary results are consistent with the idea that selected spatial parameters of a space may be embedded into a “barcode” and referenced as a type. The combination of different types, hence their parameters may be used for effective replication of their characteristics to improve the decision-making process for urban designers. The research is not intended to reproduce the successful urban public spaces but rather result in a catalogue of typologies which can be referred to during the initial stages of planning to provide an indication of spatial qualities.

summary	This paper aims to address design education issues, with a focus on the way the contemporary metropolis is conceived. We understand the reality of the contemporary metropolis as an amalgam of specific issues that transcend local and regional contexts, converging into the categories of the so-called ‘global cities’. These new urban realities derive from territories originally controlled by other logics, and are now in new stages of post-industrial development. Thus, we notice the presence of large peripheral areas where existing industrial activities initially took place, which were later transformed and migrated, leaving behind urban fragments that are taken over by informal activities. Such sites are often crossed, when not ‘on-winged’, by transport infrastructure, increasingly essential to the growing intensity of metropolitan flows. Working with this new reality clearly means first and foremost to reexamine the tools and traditional methods of design and representation of the architect and urban planner.

summary	The main instrument of urban regulation in Brazil is the plano diretor. Currently, apart from serving as a legal document, it is also the sole means of representation of the rates, zones and boundaries that it determines. However, this representation has been inefficient and, given the need to include civil society in decision - making, it becomes imperative that the impact of decisions be reviewed and communicated. As an effort to solve this problem, we propose the creation of an interface that combines information design and GIS (geographic information systems) in the format of an interactive diagram.

summary	The main goal for the architects or planners is to understand a perspective of the user. The foundation of the design process is to create buildings and environments, which will be both innovative and functional for all types of users, including adults and children. While planning the environments for children the particular aspects should be considered. The important questions are: What kind of contact does child have with the city, urban places and buildings? How does the child construct the picture of the city? What kind of urban or architectural spaces contributes to the relation that a child has with the environment? Most of the previous studies concentrating on creation of spaces for children have focused on the perspectives that have adults. According to CAADRIA 2010 paper, the objective of our study was to “learn about” (get to know the) children’s perception of everyday places. The main goal of the project was to define an appropriate tool for the design process. We identified three elements, which were considered to be the most important for child’s identification with environment: home, school, and the journey from home to school. For this purpose, children living in a residential community in Bangkok were surveyed. Contrariwise to the quantitative approach (Neisch, 2010), the concept of Colour – Code Models of space propose a qualitative development of this research – a graphic language which allow to understand the children’s spatial world, the novel way to analyze and present space, useful for educate architects and planners.

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	According to a 2008 report on world urbanization published by the United Nations, the number of people living in cities has surpassed the rural population for the first time in history. Furthermore, current projections (United Nations, 2008, 3) show that the majority of growth will occur in cities in the developing world, a tendency which will significantly contribute to the increased complexity of the urban environment. This paper is concerned with critically reflecting on the role of computation in the emergence of recent practices and strategies which intend to successfully confront the intricate performance of present and future metropolises.

summary	The creation of a 3D city model is usually a very time-consuming process and due to the constant development of the city it also has to be updated accordingly. One of the problems with large 3D city models is that they contain a huge amount of data that has to be stored and processed when it is used. The storage and management of the models are therefore a very important issue. The management issue is often that many people are collaborating and working on the 3D city model at the same time and are located at physically different locations. In this paper we present an application for collaboration, maintenance and storing of 3D city models using an open-source subversion controlled system. It is a client server based with a file-based structure on the client side. This system is not as complex as the Oracle database and is not limited to a specific file format. We have integrated the revision control system into our VR application but it is also possible to have external revision control using a default file manager, such as Explorer in Microsoft Windows. The system has been tested in three different virtual reality projects, all applied to urban planning.
