title	Role-playing planning games as educational tool - Experiences of teaching with educational games in Sweden
source	Werner, L and Koering, D (eds.), Anthropologic: Architecture and Fabrication in the cognitive age - Proceedings of the 38th eCAADe Conference - Volume 1, TU Berlin, Berlin, Germany, 16-18 September 2020, pp. 525-534

summary	Teaching about cities and planning involves complexities of understanding urban development in space and time, evolution and transformation of cities, urban politics, actors and stakeholders. Delivering efficient ways of teaching, is very important for educators, particularly among lecturers at universities who work with urban planning and design. Games can be used as educational tools and role-playing games can capture the political struggle of different actors and stakeholders involved in planning processes. Games can enable students to experience urban development and take roles of different actors and stakeholders in the planning and development processes and practice the art of negotiations in urban politics. Two educational games were written for the planning courses at KTH Royal Institute of Technology, Sweden. Since 2011, 17 games were played in different courses. Data from the evaluation forms was collected on 14 games and 277 students answered questions. This paper analyses the evaluation forms and the comments of the students who took part in the games and discusses gaming as an educational tool. The experiences with role-playing planning games are very positive. These ratings occurs consistently in each game that was played with very small variations.

summary	Performance as an architectural design paradigm has been emerging during the recent years. We have developed an understanding that we formalized as a taxonomy for performative architecture that considers performance from three points of view: health, safety and security performance; functional and efficiency performance; and psychological, social, cultural, and esthetic performance. This paper focuses on a design project that explores these ideas as a performative architecture proposal. The project focuses on the architectural transformation of the Defense Line of Amsterdam, 41 forts, as a green belt. This transformation considers a holistic approach of defining a general method and guideline. We developed a series of parametric models for the definition and generation of designs. The first model computes an urbanization level for each fort. Consequently, models are developed in 4 stages: regional design, urban design, building design, and production of a scale model, and these are applied in an iterative manner to reach design outcomes for the project.

summary	In this paper we show the structure of an urban design parametric system. The system is dynamic and builds an interactive relation with the designer updating the layout and related data at each input change. The responsiveness of the system allows the designer to gain awareness on the qualitative consequences of each design move by comparing a design state with a set of urban indicators and density measures which are automatically calculated along with the geometrical updates.

title	Parametricism for Urban Aesthetics - A flawless order behind chaos or an over-design of complexity
source	Parametricism Vs. Materialism: Evolution of Digital Technologies for Development [8th ASCAAD Conference Proceedings ISBN 978-0-9955691-0-2] London (United Kingdom) 7-8 November 2016, pp. 105-112
summary	Over the last decade, paradigm shifts in the philosophy of space-time relations, the change from space-time to spatio-temporality, caused significant changes in the design field, and introduced new variations and discourses for parametric approaches in architecture. Among all the discourses, parametricism is likely the most spectacular one. The founder of parametricism, Patrik Schumacher (2009) describes it as “a new style,” which has “the superior capacity to articulate programmatic complexity;” and “aesthetically, it is the elegance of ordered complexity in the sense of seamless fluidity.” In its theoretical background, Schumacher (2011) affiliates this style with the philosophy of autopoiesis, the philosophy that stands between making and becoming. Additionally, parametricism concerns not only the physical geometry in making of form; but also discusses the relational and causal aspects in becoming of form. In other words, it brings the aesthetic qualities in making through the topological intelligence behind becoming. Regarding that, parametricism seems an effective way of managing /creating complex topologies in form-related issues. However, when it comes to practice, there are some challenging points of parametricism in large-scale design studies. Thus, this work underlines that the dominance of elegance for urban planning has the potential of limiting the flexible and dynamic topology of the urban context, and objectifying the whole complex urban form as an over-designed product. For an aesthetic inquiry into urban parametricism, this paper highlights the challenging issues behind the aesthetic premises of parametricism at the urban design scale. For that, Kartal Master Plan Design Proposal by Zaha Hadid Architects (2006) will be discussed as an exemplary work.

title	Parametric Form-Based Codes: Incorporation of land-use regulations into Building Information Models
source	Parametricism (SPC) ACADIA Regional 2011 Conference Proceedings
doi	https://doi.org/10.52842/conf.acadia.2011.x.l7j
summary	This project describes investigations into whether parametric modeling using a Building Information Modeling (BIM) platform can represent the provisions and constraints of Form-Based Codes (FBCs). BIM software environments couple 3D modeling with parametric form generation and rich semantics. Further capabilities of an Application Programming Interface that supports Object-Oriented Programming (OOP) results in a very powerful environment for expressing planning and design concepts. While these capabilities were developed under the intention of supporting building design, we hypothesize that they can support planning rules and regulations that are found in FBCs. If our approach is successful, future planning departments will be able to provide architects and urban designers with a FBC that is implemented as a BIM software toolkit, better integrating the planning phase of a project into the building design phase.

summary	The present paper is part of an undergoing research that aims at developing software that can generate urban plans, based on contemporary urban design concepts, in an optimized way. As a design method, the project proposes the use of the trilogy formulation/ generation/evaluation, which starts with an outline of the design requirements, proceeds with the definition of generative procedures that can result in these requirements, and follows with the evaluation of the generated designs. The paper describes the development of a computer program that implements some of Marshall’s evaluation methods, and further elaborates them to define generative criteria and to optimize the resulting designs with GA techniques. The program aims at generating what Marshall calls a “characteristic structure”, a type of urban fabric that is usually found in vernacular urban fabrics.

summary	Pedestrian’s thermal comfort is of great importance in urban planning. To develop effective planning standards that prompt pedestrian comfort, a comprehensive assessment framework that takes into account pedestrian’s individual perception and behavioral is in great need. Computer simulation tools in this respect are still sparse. This paper presents the PedNaTAS system, an agent-based integrated decision support system that assesses pedestrian thermal comfort from bottom-up.

summary	In an attempt to extend our understanding of the design process in the context of computational parametric design tools, this paper explores the relationship between and interaction of synthesis and evaluation. In establishing the importance of their coupling in parametric design the paper then explores its consequence on the design process relative to existing models of designing. A tension between designing as planning, search and exploration in parametric design is highlighted together with a conceptual framework, which draws from a situated Function-Behaviour-Structure model of design. The purpose of the framework is to facilitate these different modes of designing and is targeted at the use of parametric tools.

summary	Today, with rapidly evolving information technology, computer technologies has become an interface rather than a tool for design process. With the development in computer applications it has become possible to solve design problems which were not possible to handle before. Computer environment which has become an interface rather than a tool for design has also led to the emergence of a number of concepts. New concepts such as Computer Aided Design (CAD), Computer Aided Manufacturing (CAM), Computer Aided Engineering (CAE) are being involved in design process. With the development of Artificial Intelligence (AI) , AI has earned an interdisciplinary position. Agent based systems which are contained in the fields of AI have become the subjects of many researches in design basis. Approach to the problem solving process in the process of architectural/design problems is to be addressed as an important point within the scope of evaluation process. In this context user movements have a very critical role in process of problem solving according to the design problems. While designing or solving a design problem , ignoring the user movements can lead to unwanted results. Within the scope of this study user movements in city are considered in the context of emerging urban part/particles as a preliminary study.

title	A Quantitative Method to Compare the Impact of Design Mediums on the Architectural Ideation Process.
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. 539-556.
summary	If we compare the architectural design process to a black box system, we can assume that we now know quite well both inputs and outputs of the system. Indeed, everything about the early project either feasibility studies, programming, context integration, site analysis (urban, rural or natural), as well as the integration of participants in a collaborative process can all be considered to initiate and sustain the architectural design and ideation process. Similarly, outputs from that process are also, and to some extent, well known and identifiable. We are referring here, among others, to the project representations or even to the concrete building construction and its post-evaluation. But what about the black box itself that produces the ideation. This is the question that attempts to answer the research. Currently, very few research works linger to identify how the human brain accomplishes those tasks; how to identify the cognitive functions that are playing this role; to what extent they operate and complement each other, and among other things, whether there possibly a chain of causality between these functions. Therefore, this study proposes to define a model that reflects the activity of the black box based on the cognitive activity of the human brain. From an extensive literature review, two cognitive functions have been identified and are investigated to account for some of the complex cognitive activity that occurs during a design process, namely the mental workload and mental imagery. These two variables are measured quantitatively in the context of real design task. Essentially, the mental load is measured using a Bakan's test and the mental imagery with eyes tracking. The statistical software G-Power was used to identify the necessary subject number to obtain for significant variance and correlation result analysis. Thus, in the context of an exploratory research, to ensure effective sample of 0.25 and a statistical power of 0.80, 32 participants are needed. All these participants are students from 3rd, 4th or 5th grade in architecture. They are also very familiar with the architectural design process and the design mediums used, i.e., analog model, freehand drawing and CAD software, SketchUp. In three experimental sessions, participants were asked to design three different projects, namely, a bus shelter, a recycling station and a public toilet. These projects were selected and defined for their complexity similarity, taking into account the available time of 22 minutes, using all three mediums of design, and this in a randomly manner to avoid the order effect. To analyze the two cognitive functions (mental load and mental imagery), two instruments are used. Mental imagery is measured using eye movement tracking with monitoring and quantitative analysis of scan paths and the resulting number and duration of participant eye fixations (Johansson et al, 2005). The mental workload is measured using the performance of a modality hearing secondary task inspired by Bakan'sworks (Bakan et al.; 1963). Each of these three experimental sessions, lasting 90 minutes, was composed of two phases: 1. After calibrating the glasses for eye movement, the subject had to exercise freely for 3 minutes while wearing the glasses and headphones (Bakan task) to get use to the wearing hardware. Then, after reading the guidelines and criteria for the design project (¬± 5 minutes), he had 22 minutes to execute the design task on a drawing table allowing an upright posture. Once the task is completed, the subject had to take the NASA TLX Test, on the assessment of mental load (¬± 5 minutes) and a written post-experimental questionnaire on his impressions of the experiment (¬± 10 minutes). 2. After a break of 5-10 minutes, the participant answered a psychometric test, which is different for each session. These tests (¬± 20 minutes) are administered in the same order to each participant. Thus, in the first experimental session, the subject had to take the psychometric test from Ekstrom et al. (1978), on spatial performance (Factor-Referenced Cognitive Tests Kit). During the second session, the cognitive style is evaluated using Oltman's test (1971). Finally, in the third and final session, participant creativity is evaluated using Delis-Kaplan test (D-KEFS), Delis et al. (2001). Thus, this study will present the first results of quantitative measures to establish and validate the proposed model. Furthermore, the paper will also discuss the relevance of the proposed approach, considering that currently teaching of ideation in ours schools of architecture in North America is essentially done in a holistic manner through the architectural project.

summary	In strategic planning and design, planners can benefit a great deal from planning models and simulations (2D, 3D and 4D). Carrying out strategic planning and design with the support of (spatial) models can open up a bright spectrum of opportunities and insights that were not evident before. Planning models and simulations support an awareness-raising process. In this context, space syntax also fits in. In the following we will discuss the constraints and opportunities of space syntax and show how space syntax can add value to strategic planning and design (based on the Ljubljana masterplan) for a sustainable and sustaining built environment.

title	Architecture = Computer‚ from Computational to Computing Environments
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. 217-232.
summary	Drawing on architecture, urban digital media, engineering, IT and interaction design, the research presented in this paper outlines a possible shift from architecture designed through computation (any type of process, algorithm or measurement done in a computational matter) towards architecture capable of computing (developing, using and improving computer technology, computer hardware and software as a space-defining element). The research is driven by recent developments in four fields, as follows: (a) Architecture in its recent development has shifted from a planar box, as was the ideal in the modernist movement, towards complex and non-standard forms. (b) The design concepts of non-standard surfaces have been adopted into media facades and media architecture by liberating the pixel from its planar position on a screen [1]. (c) Advancements in pervasive computing applications are now able both to receive information from the environment in which they are used and to detect other devices that enter this environment [2]. (d) Developments in advanced autonomous systems such as Human Computer Interaction (HCI) or Human Robot Interaction (HRI), have produced intelligent systems capable of observing human cues and using these cues as the basis for intelligent decision-making [3]. Media fa_ßade developments work in the direction of the above-mentioned four fields, but often come with limitations in architectural integration; they need additional components to interact with their environment and their interactions are both often limited to visual interactions and require the user to act first. The researched system, Polymedia Pixel [4] discussed in this paper, can overcome these limitations and fulfil the need for a space-defining material capable of computing, thus enabling a shift from architecture designed by computation towards architecture capable of active computing. The Polymedia Pixel architecture merges digital technology with ubiquitous computing. This allows the built environment and its relation with digital technology to develop from (a) architecture being represented by computer to (b) computation being used to develop architecture and then further to where (c) architecture and the space-defining objects have computing attributes. Hence the study presented aims to consider and answer this key question: ‚ÄòWhen building components with computing capacity can define space and function as a computer at the same time, what are the constraints for the building components and what are the possible advantages for the built environment?‚Äô The conceptual framework, design and methods used in this research combine three fields: (a) hardware (architecture and design, electronic engineering) (b) software (content design and IT) and (c) interaction design (HCI and HRI). Architecture and urban design determinates the field of application. Media architecture and computer science provide the technological foundation, while the field of interaction design defines the methodology to link space and computing [5]. The conceptual starting point is to rethink the application of computers in architecture and, if architecture is capable of computing, what kind of methodology and structure would find an answer to the above core research question, and what are the implications of the question itself? The case study discusses opportunities for applying the Polymedia Pixel as an architectural component by testing it on: (a) constraint testing ‚Äì applying computational design methodologies to design space (b) singular testing - discussing the advantages for an individual building, and (c) plural testing ‚Äì investigating the potential for an urban context. The research aims to contribute to the field of knowledge through presenting first steps of a System < - > System mode where buildings can possibly watch and monitor each other, additional to the four primary interactive modes of operation. This investigation, its proposed hypothesis, methodology, implications, significance and evaluation are presented in the paper.

title	Eye Movements on Facades – An Approach to the Concept of Visual Balance in Architecture
source	Projecting Spaces [Proceedings of the 9th European Architectural Endoscopy Association Conference / ISBN 978-3-942411-31-8 ], pp. 65-76
summary	Many of the most fundamental planning and design decisions in architecture require aesthetic judgments to be made. One decision concerns the balance of a facade composition. Balance is achieved through weighting compositional elements in order to produce stable, holistic patterns. Does this consequently mean that the balance of a facade‘s composition has an important impact on the assessment of a building _s beauty? A study was conducted to test if judgments of beauty and judgments of balance on facades go into the same direction. The question is whether balance is really experienced and incorporated when judging the aesthetic value of a building, especially by non-architects? In order to understand how people experience buildings, and how that experience informs the process of evaluation an eye-movement experiment was conducted, thus elaborating the issue of balance in a facade by measurably relating it to specific architectural design alternatives and their perception and evaluation of the beholder.

title	Analyzing the Ventilation Performance of Tropical High Density Residential Precincts using Computational Fluid Dynamics
source	Computer Aided Architectural Design Futures 2011 [Proceedings of the 14th International Conference on Computer Aided Architectural Design Futures / ISBN 9782874561429] Liege (Belgium) 4-8 July 2011, pp. 351-366.
summary	Major cities in the world are getting bigger as they continue to grow to cater for more population increase. These cities normally forced the urban planning to go high density. In the tropical context, high density cities like Singapore and Hong Kong do not have the luxury of space to go low rise and compact. These cities have to build to the floor area ratio of 4 and above to cater for the population. Their only solution is to go up, as high as possible, to the extent that the natural wind flow pattern will be altered, which brings environmental impact to the people. This is generally not good since wind flow helps to maintain the thermal comfort of the people as heat and pollutants are being channeled out of the city to avoid Urban Heat Island effect. In the tropical context, wind flow is crucial to maintain people‚Äôs comfort as the temperature is generally very high from the exposure of the sun for the entire year. Studies have shown that wind flow plays the most significant part in maintaining human comfort despite exposing to direct sunlight in the tropics. Therefore, wind flow analysis is extremely crucial to make the design sustainable and energy efficient, as people will not have to depend on mechanical ventilation to compensate for the lack of wind flow. Computational Fluid Dynamics (CFD) has always been used in the field of architecture, urban design and urban planning to understand the patterns of wind flow through the built environment apart from wind tunnel tests. The availability of more powerful hardware for the mainstream computer users as well as the lowering costs of these computers made CFD more possible to be adopted in the design world today. This also means using CFD in the design process, especially to analyze the impact of the design to the current site conditions and annual wind patterns will help the new design to be more responsive to the site. The interest of this paper is to analyze the high density typologies to see how well they respond to the local wind flow pattern. A typology is considered acceptable when the wind flow going through the site is still maintaining acceptable wind speed. This means it does not block off the wind and create stagnant spaces. Different designs generate different typologies which will respond differently to the wind pattern. The study aims at comparing the local high density typologies in terms of their response to the wind. Changes to a typology can be explored too to see if the performance will be different. For a typology which is considered a total failure in terms of response to wind, it may improve its performance if the orientation is altered. The CFD software can also parametrically respond to the changes of the typologies‚Äô dimensions. This is helpful to see how much more a typology can still be performing well before failure by increasing the floor area index. The easiest way to do this is to pump up the building height. In conclusion, designing in response to wind is extremely important as it is more sustainable and responsive to Urban Heat Island effect. A design which responds well to the wind patterns will help save cost of cooling load and fan expenditure. The people will also be more willing to use the outdoor spaces which will as a whole generate more vibrant city spaces. As a result, a high density city with huge population count can still enjoy good thermal comfort if the general urban planning and design respond well to wind.

summary	We have been witnessing an increased interest in a more holistic approach to urban design practice and education. In this paper we present a spatial data model for urban design that proposes the combination of urban environment feature classes with design process feature classes. This data model is implemented in a spatial database that becomes the backbone of a City Information Model (CIM), integrating urban neighbourhood formulation, design, and evaluation methods into a comprehensive urban design support system. We demonstrate its application to urban design analysis and evaluation through the development of a tool for AutoCAD Map 3D that is integrated with the PostGIS spatial database.

title	Computational Fluid Dynamics for Urban Design: The Prospects for Greater Integration
source	International Journal of Architectural Computing vol. 9 - no. 1, 33-54
summary	Computational Fluid Dynamics (CFD) has always been used in the field of architecture, urban design and urban planning to understand the patterns of wind flow through the built environment. Its analysis is important to evaluate whether the natural ventilation through a site is adequate to mitigate heat and pollutant to achieve better human comfort in dense urban environments. However, given the complex operational requirements, the response to wind flow is not always done early enough to support planning and design. This paper seeks to illustrate how CFD analysis can aid planning and design of urban areas and investigates the workflow requirements, in the hope of making the CFD simulations more accessible to the practices and contribute to design decisions. It also looks at the present technological advancements and future prospects to assess the scenarios where emerging technologies can make CFD simulation more readily available with affordable and even mobile hardware installations.

summary	This article is a starting point for the development of experiential urban co-design interfaces to enhance public participation in local urban projects and to be also used as a communication and collaboration tool in urban design. It is based on the previous research involving 3D city models utilized as understandable design interfaces for the non-technical public (Jutraz, Zupancic, 2011), where we have already explored different views (pedestrian, intermediate and bird’s-eye view), as well as the means by which the information obtained from these different views may be combined by shifting between viewpoints. Previous work was conducted in the “street lab” as well as the Urban Experimental Lab, which was developed specifi cally for the public’s participation in urban planning (Voigt, Kieferle, Wössner, 2009). Presented in this article is the next step that explores the immersive collaboration environment 3D ICC [1], formerly known as Teleplace. The environment was developed for effi cient collaboration and remote communication and shifts the research focus towards questions regarding how to employ both labs as interfaces between the non-technical public and design professionals. As we are facing the lack of digital systems for public participation and education in urban design, different digital tools for communication and collaboration should be combined into a new holistic platform for design. A digital system of tools needs to be developed that supports the urban design decision-making process and focuses on improved final solutions and increased satisfaction amongst all participants. In this article the system of digital tools for public participation, which include communication, collaboration and education, will be also defi ned, with its basic characteristics and its elements.

title	Spatial Experience in Real & Virtual Environment as an Urban Design Tool
source	Projecting Spaces [Proceedings of the 9th European Architectural Endoscopy Association Conference / ISBN 978-3-942411-31-8 ], pp. 59-64
summary	The innovations of information technologies and the new possibilities of multimedia exploitation in the realm of architectural design and education are supporting the development of image communication methods on the basis of interactivity. The creative process of searching and decision-making in the urban design studio of our Faculty is supported by spatial modeling methods. The draft is sketched in modeling material on a working model. From the didactic point of view, relevant are mainly those phases, in which is possible, in the imaginative way, to support the searching and decision making process with the aim to test, compare and continuously evaluate the fulfillment of the hypothetic intentions of the solution responsibilities. The model becomes an interactive medium of cooperation between teacher and the working group of students. From the view of design crystallization, the dominant phases, in the creative process, are examining, verification, and simulation. The alternatives of material-compositional content and the spatial performance charts of modeled physical structure are verifying and the visual experience of the anticipated urban environment is simulated by the author, but also through the future client’s eyes. The alternation of the composition’s spatial configurations is generally appreciated by the static visual verification in the endoscopic horizon like the architectural spatial studies. The effective method of the progress generates a creative atmosphere for the generative thinking and design. The laboratory simulation of spatial experiences and their evaluation is performed following the perception psychology relations. The simulation of digestion of the new spatial reality intervenes the customer’s identification and guides to subjective approaches towards the quality and complexity of the formed environment. The simulation is performed in motion in order to be able to anticipate the dynamic continuity of subjective spatial imagination. The induced atmosphere will direct the evaluational attitudes of authors on comparison and selection of the successful alternatives. In our fee, we will present the demonstrations of selected static and dynamic notations of image sequences prepared in our laboratory. The presentations have been created in order to analyze, verify and offer imaginative support to creative findings in result of fulfilling the studio design tasks in the educational process. The main one is the design of urban spatial structures. The laboratory methodology is in the first place oriented on the analogue-digital procedures of "endoscope" model simulation. At the same time it also explores and looks for new unconventional forms of visual communication or archiving as imagination support to specialist and laymen participants in creative, valorization and approval processes.

title	Using Geo-Located Augmented Reality for Community Evaluation
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. 701-720.
summary	Conventional practices of two-dimensional representation of three-dimensional objects remain an impediment to end-user engagement in participatory urban design. An alternative is to harness geo-located augmented reality (GAR) technology to embed life-sized virtual three-dimensional images at the actual site of proposed interventions. This format offers closest to real-life visualizations for end-users, enabling them to firstly comprehend and then express feelings concerning future proposals. This paper presents an iPhone web-app that capitalizes on the Layar browser’s GAR interface to tip the economies of scale in favor of intimately attached users of public space, rather than often remotely detached clients and their commissioned designers. Walk-around virtual images of public space designs can be viewed and commented via iPhones by the public. It further allows users to display their own ideas as alternatives, thus in effect serving as an instrument for advancement of CAAD-enabled participative environmental design in general and the idea of reclamation of authorship of public space in particular. This paper briefly describes the development of a prototype, including its preliminary evaluation, and then highlights a study to determine the 3D rendering performance parameters of GAR technology, as the core component of the idea. The paper concludes with a discussion of future implications.
