title The influence of Saudi Arabian culture on energy use: Improving the time-use schedules in energy simulation for houses in Riyadh
source Ji-Hyun Lee (Eds.) "Hello, Culture!"  [18th International Conference, CAAD Futures 2019, Proceedings / ISBN 978-89-89453-05-5] Daejeon, Korea, pp. 273-289
summary Culture influences the way that people act and behave in all societies. In Saudi Arabia, culture and beliefs directly influence the lifestyle and behaviour of its citizens. Culture also impacts on energy usage of buildings, but this factor is often excluded from energy use simulations. A consequence of this is a mismatch between energy prediction and real energy usage. This paper demonstrates how a time-use data (TUD) model can be used to create a more realistic estimate of energy consumption in Saudi Arabia. TUD has been collected through a survey of 300 people living in Riyadh. The performance of the computational TUD model is cross-referenced with empirical data and the outcomes are used to discuss how the TUD model can be applied more effectively in energy use simulations.

title Beyond Y2k: A Look at Acadia's Present and Future
source ACADIA Quarterly, vol. 18, no. 1, p. 10
summary The sky may not be falling, but it sure is getting closer. Where will you when the last three zeros of our millennial odometer click into place? Computer scientists tell us that Y2K will bring the world’s computer infrastructure to its knees. Maybe, maybe not. But it is interesting that Y2K is an issue at all. Speculating on the future is simultaneously a magnifying glass for examining our technologies and a looking glass for what we become through them. "The future" is nothing new. Orwell's vision of totalitarian mass media did come true, if only as Madison Avenue rather than Big Brother. Futureboosters of the '50s were convinced that each garage would house a private airplane by the year 2000. But world citizens of the 60's and 70's feared a nuclear catastrophe that would replace the earth with a smoking crater. Others - perhaps more optimistically -predicted that computers were going to drive all our activities by the year 2000. And, in fact, theymay not be far off... The year 2000 is symbolic marker, a point of reflection and assessment. And - as this date is approaching rapidly - this may be a good time to come to grips with who we are and where we want to be.

title Customised Collaborative Urban Design - A Collective User-based Urban Information System through Gaming
source Kepczynska-Walczak, A, Bialkowski, S (eds.), Computing for a better tomorrow - Proceedings of the 36th eCAADe Conference - Volume 1, Lodz University of Technology, Lodz, Poland, 19-21 September 2018, pp. 419-428
summary As we step into a new data-based information age, it is important to get citizens involved in the whole design process. Our research tries to build up a user-based urban information system by collecting the data of neighborhood land use preference from all the residents through gaming. The result of each individual decision will be displayed in real time using Augmented Reality technology, while the collective decision dataset will be stored, analyzed and learnt by computer, forming an optimal layout that meets the highest demand of the community. A pre-experiment has been conducted in a. an abstract virtual site and b. an existing site by collecting opinions from 122 participants, which shows that the system works well as a new method for collaborative design. This system has the potential to be applied both in realistic planning processes, as a negotiation toolkit, and in virtual urban forming, in the case of computer games or space colonization.

summary Every city has under utilized spaces that create a series of serious negative effects. Waiting for major interventions, those spaces can be reactivated and revitalized with soft temporary projects: micro interventions that light up the attention, give new meaning and add a new reading to abandoned spaces. We can call this kind of operations "plug-in design", inheriting the term from computer architecture: interventions which aim to involve the citizens and activate the environment, engage multiple catalyst processes and civil actions. Plug-in design interventions are by all meanings experimental, they seek for interaction with the users, locally and globally. Information Technology - with its parametric and site-specific capabilities and interactive features - can be instrumental to create such designs and generate a new consciousness of the existing environment. With this paper we will illustrate how two low-budget interventions have re-activated a forgotten public space. Parametric design with a specific script allowing site-specific design, materials and structure optimization and a series of interactive features, will be presented through Reciprocal 1.0 and Reciprocal 2.0 projects which have been built in 2016 in Italy by the nITro group.

summary This paper explores the sonic characteristics of urban spaces, with the application of apprehending acoustic space and form theory. The theory defines auditory spaces as acoustical arenas, which are spaces defi ned and delineated by sonic events. Historically, cities were built around a soundmark, for example, the resonance of a church bell or propagation of a calling for prayer, or a factory horn. Anyone living beyond the horizon of this soundmark was not considered citizens of that town. Furthermore, the volume of urban sonic arenas depends on natural. Digital simulation is necessary to visualize the ephemeral and temporal nature of sound, within a dynamic immersive environment like urban spaces. This paper digitally analyses the different morphologies of old cities and forms of growth in relation to the sound propagation and ecological effects. An experiment is conducted with the aid of an ancient North-African city model, exposed to a point cloud agent system. By analysing how the sound propagates from the known soundmark through the urban fabric, with the wind pressure interference; the paper compares the theoretical concept of soundmarks and the known perimeter of the ancient city

title Emerging Technololgy – Dilemma and Opportunities in Housing
source CAADRIA 2007 [Proceedings of the 12th International Conference on Computer Aided Architectural Design Research in Asia] Nanjing (China) 19-21 April 2007
summary Digital Technology has transformed industrial manufacturing and production; and an array of Industrial Design products provide increasing comfort and benefit to millions of global citizens via ergonomic and mass production/customization strategies. Yet, housing needs of a rapidly growing global population are rarely affected by digital technology. Shifts in societal demographics, from rural to urban city centres, and concurrently Global Warming and ecological changes are exacerbating the world housing situation. Millions are homeless, live in inadequate shelter, or as in the US Manufactured Housing (MH) market, live in nondurable poor quality “manufactured” houses that are detrimental to health, at best, or during extreme weather events, suffer catastrophic damages often resulting in death to occupants. Nevertheless, housing concepts and related living units have benefited very little when compared to architecture’s related manufacturing industries counter-parts (i.e. automotive, aerospace, marine industries, etc). While Technology has vividly expanded the shape language of architecture (i.e. Free-Form-Design), some may argue that Free-Form- Design buildings generally have beauty that is only “skin deep” and typically focus on providing signature statements for both the designer and elite clientele. In this paper, we will briefly review the role of the architect in the US Manufactured Housing industry; additionally, we will identify the major problems that plaque the US Manufactured Housing Industry. Further, we will review how architects and Industrial Designers use technology in their respective fields and draw larger designmanufacture principals for issues of global housing. Our findings and analysis suggest that an Industrial Design approach, applied in architecture for mass housing, offers a means of improving the architect’s role and technology in manufactured housing for the masses.

summary New technologies and uncontrolled open-data policies lead public to a new way of approaching the built environment. To enlarge the competences of the professionals that work within the cities, we believe that providing a deep and dynamic knowledge on the heritage and urban built environment is the more effective solution to offer a unique support to the needs. By providing a boosted geographical database with detailed information about the status of each building, we aim to support the professional by providing a neat vision about vacant buildings available citywide. We think this knowledge is an important asset in covering every kind of public requests: from flat to rent to an abandoned building to restore or to drive better investors. The city of Trento will be the pilot project to test these statements.We studied the phenomenon of pushing new constructions rather investing on the reuse of abandoned buildings with the consequences of unsustainable land use. To address the work we adopted a comprehensive approach across the fields of urbanism, ICT engineering and social sciences. We believe that sharing knowledge and know-hows with municipalities, agencies, and citizens is the way to support better market strategies as well as urban transformation policies.

summary This article presents a study on the representation of cities in the era of digital culture and aims to show how the phenomenon of self-production is present in the websites studied. At the end, we conclude that cities (through city marketing), local government (through advertising and through the creation of an identity) and citizens (through selfbranding), they create a rhetorical itself and constitute itself as brands. Therefore, we conclude that cybercities has been more an extended space of consumption and production of cities, municipalities and citizens.

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 Evaluating the Use of a Web-Based Collaborative Interactive Digital Model (CollABITA) in Supporting the Urban Design Approval Process1
source UMDS '02 Proceedings, Prague (Czech Republic) 2-4 October 2002, III.1-III.15
summary This research, after analyzing the Urban Development Approval Process in its functionalities and methodologies, is showing the key points at which the process might be supported by new computer technologies, and it establishes a web-based Collaborative Interactive Digital Model (CollABITA Model) that relates and facilitates the graphical representation of the urban design process with some elements of the methodological approach. The CollABITA Model will dramatically facilitate the idea of broadening public participation, and indirectly by this, also collaboration. This new web-based support tool, is focusing on how new Informative Computer Technologies can be used in order to have a more co-operative design process. By utilizing the enormous potential of Internet for informing the process, and software for visualizing its products, the Model will provide an effective support, which will be able to deliver information in various forms to the Designers, Developers, Decision Makers, Agencies and the final user (the Citizens). The Model is concerned with the big challenge of supporting the urban design approval process itself, by exploring different kind of visualizations and communication tools, rather than producing a guide for carrying out the design. CollABITA Model is based on the existent framework structure of the extranet tool already available. Then, more then those, CollABITA Model will try to solve, by adding technical and collaborative functionalities, those issues that are characteristics in the urban design process and that are not jet solved by using one of the software .

summary The paper introduces the methodology related to the topic of citizen-driven urban design and revises the idea of on-site participation of end-users, which could prospectively lead to customisation of architectural and urban space in a full-scale. The research in the first phase addresses the engagement of information technologies used for idea sketching in participatory design workshop related to local urban issues in the city of Chur in Switzerland by means of the Skity tool, the sketching on-line platform running on all devices. Skity allows user, which can be individual citizens or a community, to sketch, build, and adapt their ideas for the improvement of an urban locality. The participant is the expert of the locality because he or she lives in this place every day. The content of this paper is focused on the participatory design research project conducted as a study at the ETH Zürich and the Hochschule für Technik und Wirtschaft HTW in Chur in collaboration with Future Cities Laboratory in Singapore, mainly concentrated on the first step of the methodological approach introduced here.

title Dynamic Generative Modelling System for Urban and Regional Design
source Computer Aided Architectural Design Futures 2005 [Proceedings of the 11th International Conference on Computer Aided Architectural Design Futures / ISBN 1-4020-3460-1] Vienna (Austria) 20–22 June 2005, pp. 259-268
summary This paper introduces a dynamic generative modelling system for urban and regional design. Through dynamic modelling the system evolves in time according to the interactions of the planners, decision-makers and citizens. On the basis of several synchronous and/or asynchronous user interactions, models are dynamically generated at run time. The models are built by defining the data (datasets) and the actions to perform on that data (tasks). The system reads and correlates data at urban and regional scale from various authorities to generate dynamic datasets. Tasks are especially powerful when they integrate generative procedures in a hierarchical structure. This allows us to model urban and regional dynamics through the interaction of tasks at micro- and macro-scale. Tasks can also implement either Cellular Automata or software agents. We examine the system application to a case project: the simulation of micro- and macro-dynamics in an Alpine valley, with specific challenges to fit competitive and sustainable growth in a landscape quality perspective. The simulation in spatial and temporal dimensions of regional data provided us with the elements to study the territorial evolution over the next twenty years. Four strategies gave as many scenarios highlighting the results of specific policies.

summary This paper briefly describes the implementation of an Internet-intranet information system applied to a large-scale project. The large-scale project is centered on the urban area around the Porta Susa railway station in Turin, Italy. The information system integrates the communicative tools used to facilitate and improve the collaboration between the different actors working on the project and the distributed environment used to elaborate the information across a wide area network. The main factors considered are those which exploit the potentialities of computers and networks for interaction and communication. One result is the possibility of interacting dynamically with the information, re-elaborating and distributing it in progress. The information systems opens different ways of collaboration between the project employees, and extends the participation in the project to the citizens.

summary Sky view factor (SVF) is the ratio of radiation received by a planar surface from the sky to that received from the entire hemispheric radiating environment, in the past 20 years, it was more applied to urban-climatic areas such as urban air temperature analysis. With the urbanization and the development of cities, SVF has been paid more and more attention on as the important parameter in urban construction and city planning area because of increasing building coverage ratio to promote urban forms and help creating a more comfortable and sustainable urban residential building environment to citizens. Therefore, efficient, low cost, high precision, easy to operate, rapid building-wide SVF estimation method is necessary. In the field of image processing, semantic segmentation based on deep learning have attracted considerable research attention. This study presents a new method to estimate the SVF of residential environment by constructing a deep learning network for segmenting the sky areas from 360-degree camera images. As the result of this research, an easy-to-operate estimation system for SVF based on high efficiency sky label mask images database was developed.

summary The end of the millennium with its new digital technology is contributing important tools to the area of documentation and historical patrimony those of us who support the preservation of memories think that a very important way of personalizing and strengthening our identity is to provide to those who inhabit the city with heightened awareness towards the values of our past. The revitalization requires that the patrimony in itself be valued. At the same time, it necessitates the preparation of a great amount of information utilizing cataloguing, research databases, and other materials be accessible to all citizens. This piece of work shares the different digital data base experiences that are being developed in the CEDODAL foundation art and latinamerican architecture (center for documentation), which is under the direction of the architect Ramon Gutierrez, a research services organization, and diverse higher education institutions (universities). Four bases are introduced, each with different thought and criterion structures in the definition of fields as well as in their dynamic visualizations. Each of them possesses great quantities of digital images, blue prints, and texts. In three of those bases, the data is the output from teams of researchers in different topics through special arrangements with Santa Fe's provincial water), Fonart, and city government. At the same time, the CEDODAL catalogues its documentaries with great quantities of photographic information, blue prints, research passages, and a library.

summary “It was a fresh summer night, sky deprived of stars, and hardly any signs of life. After hours of waiting, well passed midnight, they finally allowed us to enter. I couldn’t see or hear much, except movements of those in front of me, but judging by intense scent of mildew and worm-like smell of earth, I realized my mile long underground adventure had begun. There was no looking back, only the brave steps ahead into my new, and hopefully, safe and fruitful future.” [ from diary95 ] Just like many teens around the world, I too kept a journal. It began with playful thoughts of a teenage girl, living in Sarajevo, enjoying life. On my fifteenth birthday, those carefree moments were soon replaced with brutal facts of life under siege: Sarajevo and its citizens had been surrounded by the Serbs who took over all the roads leading in and out of the city. Three years later, I was weeks away from graduating high school, and instead of getting excited, I wondered about my future…”Yesterday was awesome -- we had both electricity and water for eight straight hours…hooray!! You could see the lights miles away…the entire city was awake, making pies and bread, washing clothes, watching movies.” [ from diary93 ] Was I going to spend the rest of my life anticipating the restricted electric and water timetable? Would I wake up the next day to see all my family alive? Would I ever have a chance to fulfill my dreams? This project captures the process of [re]tracing steps of my personal journey of leaving Sarajevo to come to the United States and [re]constructing memories as a sequence of spatial events using the artifacts and the text from my war journals. The intent of my project is to define that line between the old and the new, and intertwine and merge its current condition with the facts and memories from the past. Although there was never a permanent “Berlin-wall-like” divider, the natural contours of the river and invisible screens of the snipers served as impermeable walls and divided the city for four years. The implied boundary seemed to be more powerful than the massiveness of the concrete barricades. Is it possible to re-condition something [building, space, soul] to be and feel the same when it had been destroyed and deeply scarred on the inside? Instead of placing banal memorials engraved with the bare facts, how can we make a tribute to a series of events—a time period that changed the fabric of the city—in a more three-dimensional experience? How can we integrate digital phenomenon in the process of the post-war reconstruction to re-trace the past while creating necessary advanced improvements for the new contemporary society? The impact that social conditions have on architecture, art, culture, and ultimately, people can be told in a universal language – digital storytelling, containing pieces of history and personal memories to create representations of time and space of the past, present or future.

summary The identity of an urban environment is important because it contributes to self-identity, a sense of community, and a sense of place. However, under present-day conditions, the identities of expanding cities are rapidly deteriorating and vanishing, especially in the case of Asian cities. Therefore, cities need to build their urban identity, which includes the past and points to the future. At the same time, cities need to add new features to improve their livability, sustainability, and resilience. In this paper, using data mining technologies for various types of geo-referenced big data and combine them with the space syntax analysis for observing and learning about the socioeconomic behavior and the quality of space. The observed and learned features are identified as the urban identity. The numeric features obtained from data mining are transformed into catalogued levels for designers to understand, which will allow them to propose proper designs that will complement or improve the local traditional features. A workshop in Taiwan, which focuses on a traditional area, demonstrates the result of the proposed methodology and how to transform a traditional area into a livable area. At the same time, we introduce a website platform, Quick Urban Analysis Kit (qua-kit), as a tool for citizens to participate in designs. After the workshop, citizens can view, comment, and vote on different design proposals to provide city authorities and stakeholders with their ideas in a more convenient and responsive way. Therefore, the citizens may deliver their opinions, knowledge, and suggestions for improvements to the investigated neighborhood from their own design perspective.

summary High tech industries are playing an important role in the economic development in the United States. While some cities are shrinking, the "innovation" cities are growing. The attributes that cause some cities to successfully become innovative is a very relevant 21st century topic and will be investigated here.Previous work conduct city analysis through conventional government GIS or census data but such analyses do not answer questions about the perception of citizens inhabiting the city, and the activities they conduct. The novelty of this current project is to make use of large-scale bottom-up data available from social media. Several social media sources-CrunchBase, Twitter, Yelp, and Flickr- were data mined pertaining to four innovation districts in Boston. We found that the success of innovation districts in Boston were correlated with several important variables: the most successful districts tended to occur near research institutions, in very "mixed use" areas, and were unexpectedly not correlated with land and labor prices, unlike technology districts in the past. Based on our study, we make recommendations for the urban design that cities should put in place to increase the potential for "innovation".

summary The presence of web2.0 and traceable mobile devices creates new opportunities for urban designers to understand cities through an analysis of user-generated data. The emergence of “big data” has resulted in a large amount of information documenting daily events, perceptions, thoughts, and emotions of citizens, all annotated with the location and time that they were recorded. This data presents an unprecedented opportunity to gauge public opinion about the topic of interest. Natural language processing with social media is a novel tool complementary to traditional survey methods. In this paper, we validate these methods using tourism data from Trip-Advisor in Andorra. “Natural language processing” (NLP) detects patterns within written languages, enabling researchers to infer sentiment by parsing sentences from social media. We applied sentiment analysis to reviews of tourist attractions and restaurants. We found that there were distinct geographic regions in Andorra where amenities were reviewed as either uniformly positive or negative. For example, correlating negative reviews of parking availability with land use data revealed a shortage of parking associated with a known traffic congestion issue, validating our methods. We believe that the application of NLP to social media data can be a complementary tool for urban decision making.
