title	Sketch-based Methods for Researching Building Layouts through the Semantic Fingerprint of Architecture
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. 85-102.
summary	The paper focuses on the early stages of the design process where the architect needs assistance in finding reference projects and describes different aspects of a concept for retrieving previous design solutions with similar layout characteristics. Such references are typically used to see how others have solved a similar architectural problem or simply for inspiration. Current electronic search methods use textual information rather than graphical information. The configuration of space and the relations between rooms are hard to represent using keywords, in fact transforming these spatial configurations into verbally expressed typologies tends to result in unclear and often imprecise descriptions of architecture. Nowadays, modern IT-technologies lead to fundamental changes during the process of designing buildings. Digital representations of architecture require suitable approaches to the storage, indexing and management of information as well as adequate retrieval methods. Traditionally planning information is represented in the form of floor plans, elevations, sections and textual descriptions. State of the art digital representations include renderings, computer aided design (CAD) and semantic information like Building Information Modelling (BIM) including 2D and 3D file formats such as Industry Foundation Classes (IFC) (IAI, 2010). In the paper, we examine the development of IT-technologies in the area of case-based reasoning (Richter et al., 2007) to provide a sketch-based submission and retrieval system for publishing and researching building layouts including their manipulation and subsequent use. The user interface focuses on specifying space and their relations by drawing them. This query style supports the spatial thinking approach that architects use, who often have a visual representation in mind without being able to provide an accurate description of the spatial configuration. The semantic fingerprint proposed by (Langenhan, 2008) is a description and query language for creating an index of floor plans to store meta-data about architecture, which can be used as signature for retrieving reference projects. The functional spaces, such as living room or kitchen and the relation among on another, are used to create a fingerprint. Furthermore, we propose a visual sketch-based interface (Weber et al., 2010) based on the Touch&Write paradigm (Liwicki et al., 2010) for the submission and the retrieval phase. During the submission process the architect is sketching the space-boundaries, space relations and functional coherence's. Using state of the art document analysis techniques, the architects are supported offering an automatic detection of room boundaries and their physical relations. During the retrieval the application will interpret the sketches of the architect and find reference projects based on a similarity based search utilizing the semantic fingerprint. By recommending reference projects, architects will be able to reuse collective experience which match the current requirements. The way of performing a search using a sketch as a query is a new way of thinking and working. The retrieval of 3D models based on a sketched shape are already realized in several domains. We already propose a step further, using the semantics of a spatial configuration. Observing the design process of buildings reveals that the initial design phase serves as the foundation for the quality of the later outcome. The sketch-based approach to access valuable information using the semantic fingerprint enables the user to digitally capture knowledge about architecture, to recover and reuse it in common-sense. Furthermore, automatically analysed fingerprints can put forward both commonly used as well as best practice projects. It will be possible to rate architecture according to the fingerprint of a building.

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

title	CONTESTED BOUNDARIES: Digital Fabrication + Hand Craft
source	SIGraDi 2010_Proceedings of the 14th Congress of the Iberoamerican Society of Digital Graphics, pp. Bogotá, Colombia, November 17-19, 2010, pp. 146-149
summary	This research investigates the relationship between efficiency, precision and tactile variation within architectural design and fabrication. A digitally driven design may be seamlessly precise and consistent but also feel sterile and distant from the human body. A materially driven design may be intimate and tactile but lack the accuracy needed to connect elements. Digital fabrication techniques are combined with hand craft material manipulations in search of a unique hybrid tectonic that merges connection accuracies with subtle but sensual divergences between repeating modules. Prototypes have been constructed at the object and inhabitable scale.

title	The interprofessional virtual design studio
doi	https://doi.org/10.52842/conf.caadria.2010.219

summary	With the advent of Web 2.0 technologies, the Virtual Design Studio (VDS) has been revived in many schools of architecture around the globe. The recently evolving online Social Networks (SN) Platforms, as instruments for learning, have provided a potentially fruitful operative base for VDS. Yet these platforms have not enabled the VDS to explore new frontiers. All participants come from the same professional field and learn elements directly related to their existing design curriculum. The development of the VDS for interprofessional learning moves design education beyond conventional boundaries. The Interprofessional VDS (IPVDS) is an innovative method of teaching students from two different professional faculties the skills required for successful consultancy and promotional communication in the public realm. The IPVDS enabled students to develop consultancy skills and evidence-based communication strategies appropriate for disparate target audiences. It employed a digital SN learning platform to engage remotely-located students in acquiring new skills, transferring knowledge and achieving learning outcomes that enrich their professional experience. The paper presents details of the IPVDS, its methodology, outcomes, and evaluation of the studio, and discusses how the IPVDS is effective in enabling architectural students to understand and use communication and consultancy skills for collaboration across professional disciplines for the purpose of community engagement.

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	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.

summary	With the advent of digital technology, several transformations occurred in contemporary art, such as the refusal of established structures to pragmatically use colors, forms, perspective and/or materials, as well as causing renewed references to local, regional, or singular cultures. In this context, design and artistic research migrates to new experimentation with the sensitive, intelligent, perceptive elements found within technological realms. In our research, artistic multimedia interactive installations conceal contemporary concepts and explore computer technology. We believe that this field of research is a powerful resource to develop dialogues between different cultures and promote social and technological inclusiveness.

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	(In:)forming Interactive Architectural Systems, Case of the xMAiA Meta-model
doi	https://doi.org/10.52842/conf.acadia.2010.203
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. 203-210
summary	This paper positions the domain of interactive architecture (iA) and searches for an appropriate model for structure and processing of information in the design and operation of such architecture. It is shown that there are different approaches to ways in which iA system models can be defined, each with numerous advantages and disadvantages. However, due to complexity of encountered problems, application of such models can be only partially validated by simulation and hence their design is inherently dependent on creation of operational and experiential full-scale prototypes of the systems these models represent. Another observation is the lack of correspondence between existing iA models and other contemporary models of computation for architectural geometry, fabrication and engineering. A meta-model for extensible multi-agent interactive architecture (xMAiA) is consequently proposed as a remedy to this situation. xMAiA meta-model is aimed to provide an open framework for integrated evolution, development and operation of interactive architectural systems. It delivers an extensible platform, in which diverse, project-specific models and approaches can be implemented, tested, and further evolved. Such a platform has the potential to empower agile development and operation of interactive architectural ecologies, as well as to substantially facilitate integration of creative design and experiential prototyping from day-1 of project design and development cycle. An example application conforming to the xMAiA meta-model is consequently presented and illustrated with a case study project performed in the university education context.

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.

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.

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	Architecture is the mediator between the Environment and Humans. Nature maximal performance and minimal resources creations are Humanity inspiration that led us to exceed structural, material, mechanisms, tools, systems and methods boundaries (Oxman, 2010).Nature are the Architect of the most reliable and sustainable systems. Looking into Nature's lessons, this paper presents a Nature-based design methodology conducted during Kine[SIS]tem'17 Shading Systems International Summer School, held by the ISCTE-Instituto Universitário de Lisboa, Portugal, between 19th - 30th June 2017. The methodology encompasses two main stages, one before and other during the Summer School. From a pre-definition of context constrains, a nature based design strategy, to a planning of the manufacture and construction still during the phase of development of the design, conducted the Summer School participants through a defined biomimetic process that achieved the construction of 1:1 scale prototype.

title	HYGROSCOPIC CLIMATIC MODULATED BOUNDARIES: A Strategy for Differentiated Performance Using a Natural Circulative and Energy Captive Building Envelope in Hot and Moisture Rich Laden Air Environments
source	Perkins+Will Research Journal, Vol 02.01, 41-53
summary	The operation and construction of buildings account for almost half of the energy use in the United States. To meet global climate change targets, energy consumption of buildings in the long term must be reduced as well as carbon dioxide emissions. This article explores a theoretical building envelope that generates energy and produces water by drawing water vapor out of the air to deliver new sources of water; it lowers indoor humidity in hot and humid climates. The design in this model considers materiality, surface area and environmental conditions to influence build- ing form. The case in this article considers materials and systems application in the design of the building envelope. The hygroscopic building envelope design strategically senses varying conditions of concentration and density of moisture laden air to provide visual indications of its performance. It is a building skin that emulates biological processes by creating pressure differences and transferring energy in various forms.

source	SIGraDi 2010_Proceedings of the 14th Congress of the Iberoamerican Society of Digital Graphics, pp. Bogotá, Colombia, November 17-19, 2010, pp. 304-307
summary	The main instrument of urban regulation in Brazil is the plano diretor. Currently, apart from serving as a legal document, it is also the sole means of representation of the rates, zones and boundaries that it determines. However, this representation has been inefficient and, given the need to include civil society in decision - making, it becomes imperative that the impact of decisions be reviewed and communicated. As an effort to solve this problem, we propose the creation of an interface that combines information design and GIS (geographic information systems) in the format of an interactive diagram.

summary	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	Using Case-Based Reasoning to Aid Sustainable Design
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. 241-246
summary	Since so far there exists only one planet, sustainable design is considered the (ethical) future in all fields of design. Although both architecture and construction are being considered major emitters of green house gases, a wise design not only can lead to minimizing this impact but it can also lead to restoring and regenerating the environment to a sustainable state. This paper presents an on-going research that aims at simplifying the elements and facilitating the process of sustainable design by using case-based reasoning. This is achieved through learning from past experiences; both good and bad ones, by providing a database application with a process-friendly interface which divides the main pillars of sustainable design into categories. Each building contains different stories related to different sustainable related issues. Each story can be repeated in /linked to many buildings. By providing designers with those past experiences, it is believed that deeper-studied designs can be more easily developed. Also a deeper analysis and understanding can be further implemented and produced with less effort for experienced and non-experienced architects in sustainable design. This would also decrease the consumption of time during the design process and encourage even more designers to integrate the sustainability concept into more designs. This research discusses the influence of sustainable design within the architectural domain, and suggests a computer application that aids architects during the preliminary design processes.
