summary	U-Eco City is a research and development project initiated by the Korean government. The project’s objective is the monitoring and visualization of aggregated and real time states of various energy usages represented by location-based sensor data accrued from city to building scale. The platform’s middleware will retrieve geospatial data from a GIS database and sensor data from the individual sensory installed over the city and provide the browserbased client with the accommodated information suitable to display geolocation characteristics specific to the respective energy usage. The client will be capable of processing and displaying real time and aggregated data in different dimensions such as time, location, level of detail, mode of visualization, etc. Ultimately, this system will induce a citizen’s participation with the notion of energy saving, and be utilized as an interactive energy management system from a citizen to authorities responsible for designing or developing city infrastructure. The platform’s middleware has been developed into an operative, advanced prototype, alongside a Web-based client integrates and interfaces with the Google Earth and Google Maps plug-ins for geospatially referenced energy usage visualization and monitoring.

title	Epistemología compleja de diseño arquitectónico con tecnología digital: primera generación en un taller virtual [Complex epystemology in architecture design with digital technologies: first generation at a virtual workshop]
source	SIGraDi 2010_Proceedings of the 14th Congress of the Iberoamerican Society of Digital Graphics, pp. Bogotá, Colombia, November 17-19, 2010, pp. 197-200
summary	The goal of this paper—part of a doctoral dissertation—is to define a complex epistemology of design that uses digital technology by using Edgar Morin’s study of the theory of complexity to illustrate the concepts of principles and complex paradigms in architectonic design. This paper also establishes the position of digital technology as it is strategically applied in design education in the Architectonic Project I Workshop in the FAD LUZ with participation in Las Americas Virtual Design Studio 2009.

title	Un ambiente de telecolaboración para el análisis de proyectos en arquitectura [Tellecollaboration environment for the analysis or architectural projects]
source	SIGraDi 2010_Proceedings of the 14th Congress of the Iberoamerican Society of Digital Graphics, pp. Bogotá, Colombia, November 17-19, 2010, pp. 276-280
summary	This article presents a framework based on tele - collaboration (AccessGrid) to assist in project review tasks based on 2D images as project supports. The focus of the proposed environment is: the participation of all actors, the concept of “annotations” made by participants in a project, proposal comparisons (with their respective “annotations”) and the recording of these sessions for subsequent examination and analysis. Both online and in - room tests of this environment have been performed. This allows us to evaluate the benefits offered by both in terms of the attention and participation of assistants in the revision of the project, and illustrates the value of recording the “memory” from the sessions as material that may be used in the analysis of these important exercises.

title	Humanising ICT to a Smarter Dwelling Environment
source	CAAD - Cities - Sustainability [5th International Conference Proceedings of the Arab Society for Computer Aided Architectural Design (ASCAAD 2010 / ISBN 978-1-907349-02-7], Fez (Morocco), 19-21 October 2010, pp. 221-230
summary	Dwelling environment is not intelligent if it does not include the concept of home. The emergence of ICT allowed new functions as well as new ways of performing the traditional ones. The need to be online does not remove the need of privacy and to print the site. New ways of living require rethinking dwelling typology to flexibility. Intelligent environments will appear to elevate the sense of home, where security, autonomy, independence, comfort and interaction will be crucial to promote a more qualified life. Technological solutions can be driven in different directions: energy efficiency; lightening and temperature control, video surveillance, access control, etc., assistive environments; entertainment solutions like home theater and professional ones; all have in common to conceive the environment that matches user’s expectancies, where human interaction and social participation emerge as crucial requirements.

title	Local Code: The Critical Use of Geographic Information Systems in Parametric Urban Design
doi	https://doi.org/10.52842/conf.acadia.2010.234
source	ACADIA 10: LIFE in:formation, On Responsive Information and Variations in Architecture [Proceedings of the 30th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-1-4507-3471-4] New York 21-24 October, 2010), pp. 234-242
summary	Local Code uses geospatial analysis to identify thousands of publicly owned abandoned sites in major US cities, imagining this distributed, vacant landscape as a new urban system. Deploying GIS analysis in conjunction with parametric design software, a landscape proposal for each site is tailored to local conditions, optimizing thermal and hydrological performance to enhance local performance and enhance the whole city’s ecology. Relieving burdens on existing infrastructure, such a digitally mediated, dispersed system provides important opportunities for urban resilience and transformation. In a case study of San Francisco, the projects’ quantifiable effects on energy usage and stormwater remediation would eradicate 88-96% of the need for more expensive, centralized, sewer, and electrical upgrades. As a final, essential layer, the project proposes digital citizen participation to conceive a new, more public infrastructure as well.

title	Collaborative Parametric BIM
source	CAAD - Cities - Sustainability [5th International Conference Proceedings of the Arab Society for Computer Aided Architectural Design (ASCAAD 2010 / ISBN 978-1-907349-02-7], Fez (Morocco), 19-21 October 2010, pp. 127-134
summary	The paper will be focussing on a number of digital design tools used in [our groups credentials]. A new laboratory called […] is developed with Virtual Reality for collaborative architectural design. A brief description of the systems and how they are used to support a design team is given. Synchronic and a-synchronic, local and inter-local communication is made possible. Methods for introducing sustainability in the digital design process and user participation over the Internet will be discussed. The results of the author’s PhD research “Collaborative architectural design in virtual reality” are used to develop a new approach in which team members use their own specific software. Swarm design applications developed in Virtools are used at the start of a project. The objects in the swarm can be urban and architectural functional volumes. Examples of the first are houses, offices, factories, roads and water ways. Examples of the second are working, dining, shopping and waiting spaces. Relations between the functional volumes with or without constraints make the functional volumes swarm to find equilibrium. Everything is dynamic, meaning that relations and functional volumes can change any time. Alternatives can be developed using different values for these parameters and by top-down intervention. When the final global layout has been chosen, using a criteria matrix with sustainability criteria to be judged by all participants, including the future users, a next phase is started amongst professionals using parametric design software. A study into different types of parametric design software makes clear why object parametric software can be used for IFC based BIM, while the more interesting process parametric software can not. To make this clear a pragmatic description of the IFC format is given with a simple example of such a file. Future research will be proposed in which applications of different disciplines are connected through the application programming interfaces, while integrating as much as possible the building information and knowledge in the IFC format.

title	Over Constrained
source	CAAD - Cities - Sustainability [5th International Conference Proceedings of the Arab Society for Computer Aided Architectural Design (ASCAAD 2010 / ISBN 978-1-907349-02-7], Fez (Morocco), 19-21 October 2010, pp. 179-188
summary	Parametric software has fundamentally changed the way in which architecture is conceptualized, developed and even constructed. The ability to assign parameters or numeric variables to specific portions of a project has allowed designers the potential to test variations of their design. Small changes to a single parameter can have an exponential effect on the designed object and alter its appearance beyond original preconceptions in both positive and negative ways. Parametric software also has the ability to constrain or restrict geometry to set values, parameters or conditions. This has the benefit of allowing portions of a form to remain constant or unchanged while simultaneously allowing for a great degree of flexibility in response to a design intent. Constraining portions of a design allows architects to respond to existing or unalterable conditions by ""locking down"" information within a project and then explore those portions that can change more freely. This programmed relationship between the parameter and the form, once established, can give the illusion of minimal effort for maximum output. The ease in which geometrical form can be altered and shaped by a single variable can mislead beginning designers into thinking that the software makes these relationships for them. What is hidden, is the programming or connections needed between the parameters and the geometry in order to produce such dramatic change. Finally, thinking parametrically about design reintroduces the concept of a rigorous, intent driven, fabrication oriented practice; a practice lost in a digital era where the novelty of new tools was sufficient to produce new form. Because parametric models must have established relationships to all parts of the design, each component must have a purpose, be well thought out, and have a direct relationship to a real world object. The introduction of parametric design methodologies into an architectural pedagogy reestablishes architectural praxis in an academic setting. Students are taught to design based on creating relationships to connected components; just as they would do in a professional architectural practice. This paper outlines how Digital Project – a parametric based software – was introduced into an academic setting in an attempt reconnect the ideologies of academia with the practicalities of professional practice. In order to take full advantage of Digital Project as a parameter based software, a project that creates modular, flexible geometries was devised. Produced over one semester, the project set out to find ways of controlling designed geometry through variable parameters that allowed the initial module to be instantiated or replicated into a wall condition: maintaining a unified whole of discrete components. This paper outlines this process, the results and how the outcomes demonstrates the parametric ideologies described above.

title	Developing Shared Urban Visions Through Participation Supported by Digital Tools
doi	https://doi.org/10.52842/conf.ecaade.2010.667
source	FUTURE CITIES [28th eCAADe Conference Proceedings / ISBN 978-0-9541183-9-6] ETH Zurich (Switzerland) 15-18 September 2010, pp.667-676
summary	The authors base their efforts on the assumption that future cities will only be called ‘advanced’ and ‘sustainable’ if they evolve as a shared vision between the city users / dwellers (general public) and urban designers, planners, architects, engineers (experts). For visions to be shared and planning processes to be inclusive the involvement of all (urban) actors is paramount. With the increasing urban complexity and the interrelation of phenomena there is also an increasing demand for updated, advanced and re-thought digital tools that could help in forming and enabling such common urban visions. The paper outlines the agenda and connects our on-going research efforts with the fields deemed most crucial for inclusive-for-all, successful participation that can lead to shared visions of future cities. Standing out in interchangeable order and never-ending cyclic process are: (1) education, (2) communication and (3) collaboration.

summary	Today, with technological advances the way man interacts with the world around him changes every day, bringing our field to the study of perception. For architects it has always been a challenge to represent their projects in view of the architectural object built. This study aimed to understand how immersion in virtual architectural spaces designed will facilitate greater participation of users and architects in design decisions, as well as how virtual immersion may facilitate decisions on collaborative project teams.

title	I think Therefore i-Phone: The influence of Pervasive Media on Collaboration and Multi-Disciplinary Group Work
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. 69-84.
summary	The study of value and its transfer during the multi-disciplinary process of design is stable fodder for research; an entire issue of Design Studies has been devoted to Values in the Design Process. By scrutinising design meetings Dantec (2009) and Ball (2009) separately examine the mechanisms of value transfer between the agents involved in design (clients, designers, engineers). Dantec suggests this is best understood in terms of requirement, values and narrative; Ball proposes it should be viewed as a combination of "analogical reasoning" and "environmental simulation". If we look at Vitruvius and his primary architectural manual (Pollio 1960) we find values‚Äîin the form of firmitas, utilitas and venustas‚Äîembedded in this early codification of architectural practice. However, as much current research is restricted to design practice what occurs when value frameworks move between domains of cultural activity (such as design to construction and vice-versa) is not privileged with a comparably sizable body of research. This paper is concerned with the ongoing usage of pervasive media and cellular phones within communications and value transfer across the disciplinary threshold of design and construction. Through participation in a building project we analyse the subtleties of interaction between analogue communication such as sketches and digitally sponsored communication such as e-mail and mobile phone usage. Analysing the communications between the designer and builder during construction suggests it is also a creative process and the distinctions between design and construction processes are complex and often blurred. This work provides an observational basis for understanding mobile computing as a dynamic ‚Äòtuning‚Äô device‚Äîas hypothesized by Richard Coyne (2010)‚Äîthat ameliorates the brittleness of communication between different disciplines. A follow up study deploys ‚Äòdigital fieldnotes‚Äô (dfn) a bespoke iPhone application designed to test further suppositions regarding the influence exerted upon group working by mobile computing. Within collaboration individual communiqu_©s have different levels of importance depending on the specific topic of discussion and the contributing participant. This project furthers the earlier study; expanding upon what mobile computing is and enabling us to infer how these emergent devices affect collaboration. Findings from these two investigations suggest that the synchronous and asynchronous clamour of analogue and digital tools that surround design and construction are not exclusively inefficiencies or disruptions to be expunged. Observational evidence suggests they may provide contingency and continue to have value attending to the relationship between static components‚Äîand the avoidance of failure‚Äîwithin a complex system such as design and construction.

title	Thai children’s participation in development of 3D virtual village
doi	https://doi.org/10.52842/conf.caadria.2010.423
source	Proceedings of the 15th International Conference on Computer Aided Architectural Design Research in Asia / Hong Kong 7-10 April 2010, pp. 423-431
summary	This paper present the process of virtual world’s adaptation to the vision of the real environment designed by the children of two primary Thai schools – a state school and a private school. The main point of the present paper is presentation of empirical research that is an analysis of four exercises – inquiries in which I asked children to draw the elements of their city and social life. The first task was to represent a route from home to school. Next, children were asked to draw the plan of their school, on which they had to differentiate the places dedicated to them, the common spaces and the spaces for another people. The last exercise done at school was related to the description of their family and their closest friends. At the end, the children were asked to draw an inside of their houses with the maximum of details. The results of representations of the daily life environments analysed and synthesised were rebuilt with the graphic computer tools. They will serve as the base of the conception of a 3D virtual village dedicated to the Thai children.

summary	The growing demand for sustainable architectural design motivates the integration of BIM technologies and novel design processes into architectural education. This paper presents the results from a set of educational case studies for the incorporation of BIM-based daylighting simulations and analyses into the design studio. With a carefully devised studio setting and the participation of interdisciplinary consultants, the experimental case studies simulated an integrated design process based on rapid information exchange and collaborative decision making. The implemented method enables students to use BIM models and daylighting simulations as significant sources of design information for performance-based architectural design.

title	The New Structuralism: Conceptual Mapping of Emerging Key Concepts in Theory and Praxis
source	International Journal of Architectural Computing vol. 8 - no. 4, p. 419
summary	The New Structuralism focuses upon the potential of novel design processes to return architecture to its material sources. A theoretical research presents how the structuring, encoding, and fabricating of material systems are contributing to a new material practice which demands a theoretical foundation comprehensive enough to integrate emerging theories, methods and technologies in design. Selected research works supports shared geometrical, structural and manufacturing representations and processes relevant to The New Structuralism are selected and reviewed. DDNET (Digital Design NETwork) is proposed as a conceptual structure which attempts to relate the body of these findings with theoretical constructs such as key concepts, models, techniques, technologies and leading precedents associated with The New Structuralism.

summary	Designers work in groups. They need to share information either synchronously or asynchronously as they work with parametric modeling software, as with all computer-aided design tools. Receiving information from collaborators while working may intrude on their work and thought processes. Little research exists on how the reception of design updates influences designers in their work. Nor do we know much about designer preferences for collaboration. In this paper, we examine how sharing and receiving design updates affects designers’ performances and preferences. We present a system prototype to share changes on demand or in continuous mode while performing design tasks. A pilot study measuring the preferences of nine pairs of designers for different combinations of control modes and design tasks shows statistically significant differences between the task types and control modes. The types of tasks affect the preferences of users to the types of control modes. In an apparent contradiction, user preference of control modes contradicts task performance time.

doi	https://doi.org/10.52842/conf.ecaade.2010.677
source	FUTURE CITIES [28th eCAADe Conference Proceedings / ISBN 978-0-9541183-9-6] ETH Zurich (Switzerland) 15-18 September 2010, pp.677-686
summary	This paper presents research in response to environmental concerns we face today. In a search for a better method to manage spaces and building resources consumed excessively through traditional top-down architectural solutions, the research began by speculating that the building spaces and resources can be managed by designing architectural systems that encourage a bottom-up approach. In other words, this research investigates how to design systems that encourage occupants and users of buildings to actively understand, manage and customise their own spaces. Specific attention is paid to the participation of building users because no matter how sophisticated the system is, the building will become as wasteful as conventional buildings if users cannot, or do not want to, utilise the system effectively. The research is still in its early stages. The intension of this paper is to provide a background to the issue, discuss researches and projects relevant to, but not necessarily about, architecture, and introduce a number of hypothesis and investigations to realise adaptable, participatory and sustainable environments for users.

summary	Novice designers are gaining increased access to CAD tools for design computing and digital fabrication that were once exclusively used by expert designers. As evidenced by the rise in manufacturing incubation facilities, novices can prototype their ideas in ways similar to expert designers. Also available for novice designers are online rendering consultants, online manufacturing and online ecommerce as a way to distribute and sell products. Discussed here are the reasons for this emergence, complications when using design and digital fabrication as a standard mode of production and new focus for experts.

title	Interactive message wall: a public display for collective sharing in real and virtual place
doi	https://doi.org/10.52842/conf.caadria.2010.487
source	Proceedings of the 15th International Conference on Computer Aided Architectural Design Research in Asia / Hong Kong 7-10 April 2010, pp. 487-496
summary	In this paper, we propose a design of an interactive message wall as a public display for large group setting such as a university community to encourage user participation, social interaction and creation of user content. It is a public display for collective sharing of thoughts. It is also a portal for online users to make their presence felt in the physical place. Both users at the physical place and in an online virtual world can post messages to the interactive message wall. The paper will present user studies carried out with a mock-up message wall to establish how onsite users use it, their preferred ways to leave messages, what medium of content (voice, photo, text, video) they are willing to share, and user participation. The results of the user studies will inform the design of the interactive message wall and provide learning points on how to promote user participation.

summary	Cities have always been locations of densified collections of various kinds of networks. While usually networks are conceived as a kind of immaterial logistic devices, we emphasize another quality of networks, their capabilities for associative learning. We propose autonomous associative networks in their probabilistic flavor, such as so-called Self-Organizing Maps, as abstract candidate structures for simulation experiments and as actualized structures of real cities as well. The properties of Self-Organizing Maps allow to introduce a whole new area of analytical procedures to conceive of the city and its properties. It also makes it possible to operationalize the attractivity of cities or the success of the implementation of urban planning.

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.
