summary Informal settlements consisting of substandard housing that lack adequate infrastructure, sanitation, living space and security, are one of the major challenges for developing cities in terms of their unpredictable growth. The colonias are informal settlements that originated in substandard housing development in the U.S. along the Mexico border. As informal settlements grow and transform into formal communities, their potential impacts upon energy consumption and economic development can be very high. This study proposes a method by using Building Information Modeling (BIM) parametric tool to develop a database of informal houses in the colonias that would assist the planning of development and upgrades.

summary Sustainable design and ecological building are the most significant global challenges for the design profession. To meet new building regulations and national targets for carbon emissions, all future buildings will be judged on their ‘green’ merits. For architects to maintain a competitive edge in a global market, innovation is now key; the design of new processes, technologies and materials that combat carbon emissions and improve the sustainable performance of buildings are paramount. Contemporary practices have responded by setting up multi- disciplinary internal research and development teams, with offices such as Foster + Partners, HOK and Aedas setting the bar for ground-breaking research and development. The aim of internal groups is often to adapt and create new technologies and materials and to borrow ways of working from other disciplines, to focus on innovation rather than incrementally increasing performance or efficiency. This title offers insights into how a wide range of established and emerging practices are rising to meet these challenges. In pursuit of integrated sustainability and low-energy building, material and formal innovation and new tools and technologies, it illustrates that the future of architecture is evolving in an exchange of ideas across disciplines. Incorporating the creation of new knowledge about ecological building within the profession, it also identifies the emergence of a collective will to seek out new routes that build in harmony with the environment.

title Integrated Design and Building System for the Provision of Customized Housing: the Case of Post-Earthquake Haiti
source Computer Aided Architectural Design Futures 2011 [Proceedings of the 14th International Conference on Computer Aided Architectural Design Futures / ISBN 9782874561429] Liege (Belgium) 4-8 July 2011, pp. 247-264.
summary The paper proposes integrated design and building systems for the provision of sustainable customized housing. It advances previous work by applying a methodology to generate these systems from vernacular precedents. The methodology is based on the use of shape grammars to derive and encode a contemporary system from the precedents. The combined set of rules can be applied to generate housing solutions tailored to specific user and site contexts. The provision of housing to shelter the population affected by the 2010 Haiti earthquake illustrates the application of the methodology. A computer implementation is currently under development in C# using the BIM platform provided by Revit. The world experiences a sharp increase in population and a strong urbanization process. These phenomena call for the development of effective means to solve the resulting housing deficit. The response of the informal sector to the problem, which relies mainly on handcrafted processes, has resulted in an increase of urban slums in many of the big cities, which lack sanitary and spatial conditions. The formal sector has produced monotonous environments based on the idea of mass production that one size fits all, which fails to meet individual and cultural needs. We propose an alternative approach in which mass customization is used to produce planed environments that possess qualities found in historical settlements. Mass customization, a new paradigm emerging due to the technological developments of the last decades, combines the economy of scale of mass production and the aesthetics and functional qualities of customization. Mass customization of housing is defined as the provision of houses that respond to the context in which they are built. The conceptual model for the mass customization of housing used departs from the idea of a housing type, which is the combined result of three systems (Habraken, 1988) -- spatial, building system, and stylistic -- and it includes a design system, a production system, and a computer system (Duarte, 2001). In previous work, this conceptual model was tested by developing a computer system for existing design and building systems (Benr__s and Duarte, 2009). The current work advances it by developing new and original design, building, and computer systems for a particular context. The urgent need to build fast in the aftermath of catastrophes quite often overrides any cultural concerns. As a result, the shelters provided in such circumstances are indistinct and impersonal. However, taking individual and cultural aspects into account might lead to a better identification of the population with their new environment, thereby minimizing the rupture caused in their lives. As the methodology to develop new housing systems is based on the idea of architectural precedents, choosing existing vernacular housing as a precedent permits the incorporation of cultural aspects and facilitates an identification of people with the new housing. In the Haiti case study, we chose as a precedent a housetype called “gingerbread houses”, which includes a wide range of houses from wealthy to very humble ones. Although the proposed design system was inspired by these houses, it was decided to adopt a contemporary take. The methodology to devise the new type was based on two ideas: precedents and transformations in design. In architecture, the use of precedents provides designers with typical solutions for particular problems and it constitutes a departing point for a new design. In our case, the precedent is an existing housetype. It has been shown (Duarte, 2001) that a particular housetype can be encoded by a shape grammar (Stiny, 1980) forming a design system. Studies in shape grammars have shown that the evolution of one style into another can be described as the transformation of one shape grammar into another (Knight, 1994). The used methodology departs takes off from these ideas and it comprises the following steps (Duarte, 2008): (1) Selection of precedents, (2) Derivation of an archetype; (3) Listing of rules; (4) Derivation of designs; (5) Cataloguing of solutions; (6) Derivation of tailored solution.

title 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’s 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’ 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.

title Sustainable Planning with a Synergetic Collation of Thermal and Dynamic Characteristics of Urban Climate using Map Based Computational 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. 367-382.
summary Since 2006, half of the world’s population lives in cities. In the age of climate change, designing for quality environmental living conditions and sustainability is a topical concern. However, on the one hand, designers and city planners operate with their three dimensional city morphological data such as building shapes and volumes, forms and their spacings, and functional attributes and definition signatures. On the other hand, urban climatologists operate with their numbers and equations, quantities and signals, and normals and anomalies. Traditionally the two camps do not meet. It is a challenge to develop design tools that they can work together. Map based information system based on computational geographic information system (GIS) that is properly structured and represented offers a common language, so to speak, for the two professional groups to work together. Urban climatic map is a spatial and graphical tool with information embedded in defined layers that are collated so that planners and urban climatologists can dialogue over design issues. With various planning and meteorological data coded in defined grid resolutions onto the GIS map system, data can be synergized and collated for various understandings. This papers explains the formulation of Hong Kong’s GIS based Urban Climatic Map as an example of how the map works in practice. Using the map, zonal and district based planning decisions can be made by planners and urban climatologists that lead to new designs and policy changes.

title Mass-Customization in the Design of 4,000 Bus Stops
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. 265-278.
summary In Hawaii, ‚"TheBus‚" has been a main transportation system since 1971. Considering the high cost of living in Hawaii and the absence of a rail system, the use of ‚"TheBus‚" has been an instrumental vein of the city life in Honolulu with rhythmical pauses at about 4,000 bus stops in Honolulu. However, existing undifferentiated bus stops are developed from a cost effective mass production system so that they have been problematic for satisfying specific needs from various site conditions. In this research, an integrated computational method of mass-customization for designing 4,000 bus stops is introduced. According to various site conditions, the design of each bus stop is customized. Unlike the mass‚Äêproduced bus stops commonly seen in cities today, the proposed computational method in this paper produces bus stop design outcomes that fit into the physical characteristics of the location in which they are installed. Mass-customization allows for the creation and production of unique or similar buildings and building components, differentiated through digitally‚Äêcontrolled variation (Kolarevic, 2003). The employment of a computational mass‚Äêcustomization in architectural design extends the boundary of design solutions to the satisfaction of multi-objective requirements and unlimited freedom to search alternative solutions (Duarte, 2001; Caldas, 2006). The computational method developed in this paper consists of 1) definition of a prototype, 2) parametric variation, 3) manual deformation, and 4) simulation based deformation. The definition of a prototype is the development of a basic design to be transformed for satisfying various conditions given from a site. In this paper, the bus stop prototype is developed from the analysis of more than 300 bus stops and the categorization of the existing bus stops according to their physical conditions, contextual conditions, climatic conditions, and existing amenities. Based upon the outcome of the analysis, the design variables of a bus stop prototype are defined. Those design variables then guide the basic physical parameters for changing the physical configuration of the prototype according to a given site. From this, many possible design outcomes are generated as instances for further developments. The process of manual deformation is where the designer employs its intuition to develop the selected parametric variation. The designer is compelled to think about the possible implication derived from formal variation. This optional process allows every design decision to have a creative solution from an individual designer with an incidental quality in aesthetics, but substantiated functional quality. Finally the deformation of the selection is guided and controlled by the influence of sun direction/ exposure to the selection. The simulation based deformation starts with the movement of the sun as the trigger for generating the variations of the bus stop prototype. The implementation of the computational method was made within the combination of MEL (Maya Enbedded Language), autodesk MAYA and Ecotect environment.

title Crowdsourcing Urban Simulation Platform Using Mobile Devices and Social Networking Media Technologies

summary Introduction and Research Questions The research area of urban simulation methods has grown notably in recent decades. Most of the research topics that concern urban simulation have concentrated on defining the complexities of urban environments with certain rules and algorithms. However, cities are getting more complex and changes to them are being made at greater speed. Therefore, current urban simulation modeling approaches based on rules and protocols are still struggling to reduce the gap between the virtual simulation environment and the real cities, since the behavior of citizens is frequently unpredictable and continuously adapting. In this context, research is necessary to develop more fundamental simulation methods that can handle these complexities and changes, leading to new design decision support systems. Therefore, this research was motivated with the following questions: What is the origin of the complexities and transformations of the urban environment? How can we approach the origin to deal with the urban complexities and transformations? To answer these questions, we hypothesize that the diverse human intentions are the origin of the issues that result from all of the complexities and changes of the cities. General Objectives As a result, we propose a participatory simulation environment that brings human intention into the urban simulator: a crowdsourcing [1] simulation platform that is operated by the people‚Äôs participation. To achieve this crowdsourcing urban sustainability simulation environment, we must address the following research issues: categorization of urban sustainability indicators and technologies, inducing mass participations, and an implementation of social network services. Furthermore, we aim at using mobile computing devices, such as smart phones, as a terminal to the simulation environment. Fundamental Goals Our goal is to enable people to share urban information at any time and to compare each other‚Äôs contributions through the crowdsourcing urban simulation platform. The information will be returned to the citizens to support their sustainability-aware life. The simulation platform also gives a chance not only to compare each other‚Äôs levels of sustainability, but also to give self-satisfaction through an altruistic contribution for a sustainable future. Thus, people shall utilize the simulator in order to predict their individual or cities‚Äô future sustainability. Meanwhile, the user data will be collected and delivered to the central server in order to analyze the urban sustainability. Consequently, we can measure the urban sustainability based on a real human interaction, and compare individuals as well as cities. The whole process of this research is presented as a new paradigm of an urban simulator that reflects the urban complexities and the inconstant human mind changes. Specific Objectives of This Paper This paper will represent strategies of the crowdsourcing urban simulation which can make a paradigm shift of urban simulation and shall define the customized sustainable indicators for the initial steps of this research. It shows how as system for can communicate with the public using the current technologies: high performance mobile media, social network services and wide-area geospatial information systems. Furthermore, for the first step of this research, the paper defines the urban sustainability indicators, and their categorization is generalized and translated into simpler ways to support the citizen‚ intuitive understanding.

summary This paper presents a methodology to augment acoustically the experience of the urban environment by mapping its fundamental spatial elements and translating them to sound and music. The methodology can be applied at any given path of an urban network to generate its acoustical representation with sounds produced by appropriately chosen musical instruments. The objective is twofold. On the one hand it targets the amelioration of the urban experience of people with impaired vision while on the other it offers a more synaesthetic spatial perception to all those who rely mostly on their retinal understanding of the environment.

title The Architecture of Flows: Integrated Infrastructures and the ‘Metasystem’ of Urban Metabolism
source ACADIA 11: Integration through Computation [Proceedings of the 31st Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA)] [ISBN 978-1-6136-4595-6] Banff (Alberta) 13-16 October, 2011, pp. 40-43
doi https://doi.org/10.52842/conf.acadia.2011.040
summary The traditional approach to urban design studies has been based on what can be described as a generalised anatomical model, e.g., functional zoning coupled to metaphors such as green areas serving as the ‘lungs’ of cities. Despite the frequent use of biological metaphors, urban design has generally proceeded from an understanding of cities as static arrays of buildings and infrastructures that exist in, but are distinct from, stable environments. But this approach does not reflect the dynamic systems of cities throughout history, nor their close coupling to the dynamics of their local environment, climate and ecology, and now the global dynamics of culture and economy. The limitations of this approach, in which cities are treated as discrete artefacts, rather than nodes interconnected by multiple networks, are compounded by the legal and regulatory boundary of the city usually being defined as an older core, so that cities are regarded as something quite separate from their surrounding territory. All cities have administrative boundaries, but cities are very rarely either physically or energetically contained within those administrative boundaries. In the past, cities gathered most of the energy and materials they needed from their immediate local territory, and trade linked systems of cities across whole regions. The growth and vitality of many cities are no longer dependent on the spatial relationship with their immediate environs but on the regional and global flows of resources. The flow of materials, information and energy through cities comes from far outside their physical and regulatory (municipal) boundaries. Cities now extend their metabolic systems over very great distances, so that the extended territory of the urban metabolism of a city and its geographical ‘place’ are often completely decoupled.

title Automated Cost Analysis of Concept Design BIM Models
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. 403-418.
summary AUTOMATED COST ANALYSIS OF CONCEPT DESIGN BIM MODELS Interoperability: BIM models and cost models This paper introduces the automated cost analysis developed for the General Services Administration (GSA) and the analysis results of a case study involving a concept design courthouse BIM model. The purpose of this study is to investigate interoperability issues related to integrating design and analysis tools; specifically BIM models and cost models. Previous efforts to generate cost estimates from BIM models have focused on developing two necessary but disjoint processes: 1) extracting accurate quantity take off data from BIM models, and 2) manipulating cost analysis results to provide informative feedback. Some recent efforts involve developing detailed definitions, enhanced IFC-based formats and in-house standards for assemblies that encompass building models (e.g. US Corps of Engineers). Some commercial applications enhance the level of detail associated to BIM objects with assembly descriptions to produce lightweight BIM models that can be used by different applications for various purposes (e.g. Autodesk for design review, Navisworks for scheduling, Innovaya for visual estimating, etc.). This study suggests the integration of design and analysis tools by means of managing all building data in one shared repository accessible to multiple domains in the AEC industry (Eastman, 1999; Eastman et al., 2008; authors, 2010). Our approach aims at providing an integrated platform that incorporates a quantity take off extraction method from IFC models, a cost analysis model, and a comprehensive cost reporting scheme, using the Solibri Model Checker (SMC) development environment. Approach As part of the effort to improve the performance of federal buildings, GSA evaluates concept design alternatives based on their compliance with specific requirements, including cost analysis. Two basic challenges emerge in the process of automating cost analysis for BIM models: 1) At this early concept design stage, only minimal information is available to produce a reliable analysis, such as space names and areas, and building gross area, 2) design alternatives share a lot of programmatic requirements such as location, functional spaces and other data. It is thus crucial to integrate other factors that contribute to substantial cost differences such as perimeter, and exterior wall and roof areas. These are extracted from BIM models using IFC data and input through XML into the Parametric Cost Engineering System (PACES, 2010) software to generate cost analysis reports. PACES uses this limited dataset at a conceptual stage and RSMeans (2010) data to infer cost assemblies at different levels of detail. Functionalities Cost model import module The cost model import module has three main functionalities: generating the input dataset necessary for the cost model, performing a semantic mapping between building type specific names and name aggregation structures in PACES known as functional space areas (FSAs), and managing cost data external to the BIM model, such as location and construction duration. The module computes building data such as footprint, gross area, perimeter, external wall and roof area and building space areas. This data is generated through SMC in the form of an XML file and imported into PACES. Reporting module The reporting module uses the cost report generated by PACES to develop a comprehensive report in the form of an excel spreadsheet. This report consists of a systems-elemental estimate that shows the main systems of the building in terms of UniFormat categories, escalation, markups, overhead and conditions, a UniFormat Level III report, and a cost breakdown that provides a summary of material, equipment, labor and total costs. Building parameters are integrated in the report to provide insight on the variations among design alternatives.

title Responsive and Autonomous Material Interfaces

doi https://doi.org/10.52842/conf.acadia.2011.318
summary This paper presents continuing research on responsive systems in architecture; the ability of architectural systems to change certain properties in response to their surrounding environmental pressures. While doing so, it shifts from current and past examples of mechanical approaches of adaptation, towards biological paradigms of seamless material integration. Looking at biological mechanisms of growth and focusing on the material make-up behind them, the research proposes the exploration of material systems in a two-fold interrelated manner: firstly, through passive material systems of variable elasticity, and secondly through the embedment of smart materials with shape-changing properties. The combination of the two is aiming at architectural systems of functional versatility.Through an interdisciplinary approach, the paper examines the following questions: Is it possible to envisage structures that share the principles of adaptation and response of living organisms? What are the technological challenges faced when designing self-actuated responsive interfaces? Which is the conceptual framework for understanding and investigating complex adaptive and responsive systems? By exploring and synthesizing theories and tools from material science, bioengineering and cybernetics the aim is to inform architectural interfaces able to enhance interconnectivity between the man-made and the natural. Focusing on the self-organization of material systems the intention is to suggest architectural interventions, which become sub-systems of their ecological milieu. The emphasis therefore is placed not on architectural formalism, but on how we can define synthetic environments through constant exchanges of energy, matter and information.

title Digital Materiallurgy: On the productive force of deep codes and vital matter
source ACADIA 11: Integration through Computation [Proceedings of the 31st Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA)] [ISBN 978-1-6136-4595-6] Banff (Alberta) 13-16 October, 2011, pp. 90-97
doi https://doi.org/10.52842/conf.acadia.2011.090
summary This paper expands the discourse surrounding digital forms of making by scrutinizing the role of materials within computation, ultimately proposing a speculative working model that charts new territory. The growing importance of materials within technological research makes this an appropriate time to consider the nuance of their role within it. Currently, material innovation is happening along two central tracks: the customized cutting, sculpting, and forming of conventional materials with Computer Numerically Controlled (CNC) fabrication equipment and the development of new materials through innovations in material science. Both tracks rely on a limited set of material protocols which enable process-based control and eliminate the intrusion of any unpredictable material variable. Although efficient, such an approach limits architecture’s ability to procure novel material engagements. A few designers are developing an alternative model where computational codes are coupled with eccentric materials to produce unusual results. Digital materiallurgy, as I have called it, is part technique and part attitude; it relies on intentionally ceding limited design control to unpredictable matter—thus capitalizing on matter’s innate ability to produce unexpected formal and material complexity. Digital materiallurgy identifies the intersection of computation and eccentric materiality as a departure point for architectural innovation. By purposefully inserting material heterogeneity and inconsistency into computational means and methods, this work pries apart the apparently seamless relationship between digital design and physical production. By blurring the distinction between physical material and digital form, this work offers an integrated aesthetic experience, one that fetishizes neither the virtual nor the vintage but fuses both into a richer, wilder present.

summary This paper argues that learning to design parametrically in the architectural studio entails gains but also losses, since the parametric design approach tends to and encourage certain patterns of thought while discouraging others. This investigation complements previous research focusing mostly on technological aspects. Based on observational data from a parametric design studio in China, this paper discusses how parametric designing can pose challenges to existing design values and approaches, specifically within a Chinese context. It further draws attention to the limitations of parametric designing, which in the observed cases required both students and teachers to break and extend parametric models besides and beyond parametric variation to make them work architecturally. This paper aims to inform educators employing parametric designing in their architectural design studios as well as researchers who examine such studios.

summary Neighborhoods that are still outside the market target can find alternative ways of re-development. Therefore, it is necessary to design architectures compatible with their fragile ecologies. This research benefits from a previous study where we tried to observe the evolution of the uses of buildings and ways of living faced with changes in environmental conditions in a given urban context. Increased automobile traffic has led to changes in the use of residential spaces whose function was gradually replaced by commercial activities. Making use of graphic-oriented interpretation of urban ambiance and landscape analysis methodology applied to the design of different floor levels, this paper aims to introduce the concept of sensitive tower defined on the basis of observations made in our post-occupancy survey as a teaching strategy for the design studio faced with the current challenges of the contemporary metropolis.

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 “design challenges on a much larger scale as we become an increasingly global and technological society” (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 – such as Second Life and There – 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.

title Utilizing a Web-based Geographic Virtual Environment Prototype for the Collaborative Analysis of a Fragile Urban Area: An “Open-Source” International Urban Design Studio organized in Brussels

summary In this paper, we will discuss the opportunities and challenges of using a Web-based Geographic Virtual Environment Prototype, primarily developed in the framework of a long-term research project by Pak and Verbeke (2011), as a complementary medium to support an international urban design studio. We reconfigured and rescaled this prototype with the objective of encouraging students to make a collaborative, open-source and location-based analysis of the fragile project area (the Brussels-Charleroi Canal) and share their findings with each other. During this eight week long experimental study, the students were able to effectively use the environment during the analysis phase of the urban design studio; despite their heterogeneous profiles. They created an online inventory that covers five gigabytes of analysis findings, sketches, photos, maps, studio presentations and texts describing their experiences. This environment shows the power of crowdsourcing and online collaborative analysis. Moreover, the findings of our online student survey demonstrate a general positive attitude towards the use of the Virtual Environment Prototype.

title An Urban Information Framework to support Planning, Decision-Making & Urban Design
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. 653-668.
summary This paper reports on a 2-year research project undertaken in collaboration with a state planning authority, a major city municipal council and a government-owned development organisation. The project has involved the design of an urban information model framework with the aim of supporting more informed urban planning by addressing the intersection where an individual building interfaces with its urban context. This adopted approach enables new techniques that better model the city and its processes in a transparent and accessible manner. The primary driver for this project was the challenge provided by the essential incompatibility between legacy GIS (geographic information system) datasets and BIM (building information model) representations of the built form. When dealing with urban scale information, GIS technologies use an overlay mapping metaphor linked to traditional relational database technologies to identify features or regions in the urban landscape and attach attribute data to those in order to permit analysis and informed assessment of the urban form. On the other hand, BIM technologies adopt an object-oriented approach to model the full three-dimensional characteristics of built forms in a way that captures both the geometric and physical attributes of the parts that make up a building, as well as the relationships between those parts and the spaces defined by the building fabric. The latter provides a far richer semantic structure to the data, while the former provides robust tools for a wide range of urban analyses. Both approaches are widely recognised as serving well the needs of their respective domains, but there is a widespread belief that we need to reconcile the two disparate approaches to modelling the real world. This project has sought to address that disjunction between modelling approaches. The UrbanIT project concentrated on two aspects of this issue: the development of a framework for managing information at the precinct and building level through the adoption of an object-oriented database technology that provides a platform for information management; and an exploration of ontology tools and how they can be adopted to facilitate semantic information queries across diverse data sources based on a common urban ontology. This paper is focussed on the first of those two agendas, examining the context of the work, the challenges addressed by the framework and the structure of our solution. A prototype implementation of the framework is illustrated through an urban precinct currently undergoing renewal and redevelopment, finishing with a discussion of future work that comes out of this project. Our approach to the implementation of the urban information model has been to propose extensions to ISO/PAS 16739, the international standard for modelling building information that is commonly known as IFC (Industry Foundation Classes). Our reason for adopting that approach is primarily our deep commitment to the adoption of open standards to facilitate the exchange of information across the built environment professions, but also because IFC is based on a robust object schema that can be used to construct a internet-accessible database able, theoretically, to handle the vast quantity of data needed to model urban-scale information. The database solution comes with well-established protocols for handling data security, integrity, versioning and transaction processing or querying. A central issue addressed through this work is concerned with level of detail. An urban information model permits a very precise and detailed representation of an urban precinct, while many planning analyses rely on simplified object representations. We will show that a key benefit of our approach is the ability to simultaneously maintain multiple representations of objects, making use of the concept of model view definitions to manage diverse analysis needs.

title Integrated Design Process for Prefabricated Façade Modules with Embedded Distributed Service Systems
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. 419-434.
summary The awareness of the environmental impact of buildings concerning their CO2 emissions, their energy and resource consumption has raised the challenges on building design, construction and operation. Building service systems are among the main contributors to building related emissions. Their consideration already in design is therefore of growing importance. Distributed service systems represent a new paradigm towards the supply of a building with energy and matter. Being small, efficient and networked, they can be distributed within the building fabric to allow an efficiently supply of the building space. Their employment, however, affects the spatial layout, construction and resulting building performance. In order to capture the resulting complex dependencies, a strategy to integrate such systems into the architectural design process is necessary. In this work a design process is proposed, that integrates distributed service systems into building design, dissolving the classical divide between architectural design and service systems layout. Digital modelling and computational methods are employed to create and analyse design solutions, visualize performance criteria and provide the relevant data for the intended digital fabrication process. The process is exemplified using a joint university-industry case study project focusing on parametric façade modules, developed in a seamless digital process from concept to fabrication.
