title	Towards a dynamic evacuation system: developing methodologies to simulate the evacuation capabilities of subway stations in response to a terrorist attack with CBRNE weapons
source	Thompson, Emine Mine (ed.), Fusion - Proceedings of the 32nd eCAADe Conference - Volume 1, Department of Architecture and Built Environment, Faculty of Engineering and Environment, Newcastle upon Tyne, England, UK, 10-12 September 2014, pp. 109-118

summary	Events in recent times have highlighted the vulnerability of underground public transportation to possible terrorist attacks. A key question therefore is how an evacuation can be accomplished from underground stations safely. The strategy “go up and take the nearest exit to the surface” might not be the best response. Evidence from the Daegu subway station fire in 2003, investigated by Tsujimoto (2003) and Jeon and Hong (2009) establish that smoke or toxic airborne substances from a terrorist attack tend to use the same direct routes used by the fleeing passengers and as result significant injuries or fatalities can occur. This study proposes the concept of a dynamic evacuation system which would guide subway users along safe routes. To test how this system may operate, the study discussed combines measurements from tracer gas experiments with climate measurements to establish how toxic agents spread in subway stations under certain conditions and combines these results with those from pedestrian simulations applied to calculate evacuation times for possible escape routes. By integrating the resulting dataset from these methods, an evidence base of how a dynamic evacuation system may work can start to form.

title	Automatic Extraction of Planar Clusters and their Contours on Building Facades Recorded by Terrestrial Laser Scanner
source	International Journal of Architectural Computing vol. 7 - no. 1, 1-20
summary	Since 3D city models need to be realistic not only from a bird's point of view, but also from a pedestrian's point of view, the interest in the generation of 3D façade models is increasing. This paper presents two successive algorithms for automatically segmenting building façades scanned by Terrestrial Laser Scanner (TLS) into planar clusters and extracting their contours. Since majority of façade components are planes, the topic of automatic extraction of planar features has been studied. The RANSAC algorithm has been chosen among numerous methods. It is a robust estimator frequently used to compute model parameters from a dataset containing outliers, as it occurs in TLS data. Nevertheless, the RANSAC algorithm has been improved in order to extract the most significant planar clusters describing the main features composing the building façades. Subsequently, a second algorithm has been developed for extracting the contours of these features. The innovative idea presented in this paper is the efficient way to detect the points composing the contours. In order to evaluate the performances of both algorithms, they have successively been applied on samples with different characteristics, i.e. densities, types of façades and size of architectural details. Finally, a quality evaluation based on the comparison of planar clusters and contours obtained manually has been carried out. The results prove that the proposed algorithms deliver qualitative as well as quantitative satisfactory results and confirm that both algorithms are reliable for the forthcoming 3D modelling of building façades.

title	Finding Your Way Around Heritage Sites: the Delivery of Digital Information to Mobile Devices
source	International Journal of Architectural Computing vol. 7 - no. 1, 105-120
summary	An information enriched 3D digital city model connected wirelessly with the real-time user interaction has the potential to deliver an effective piece in the pervasive computing jigsaw. Real-time location awareness can contribute to the effective delivery of 3D digital city models and associated information to small mobile devices. Location awareness is also one of the vital elements of ubiquitous computing systems; together the mobile hardware and its interactive contents can be thought of as 'everyware'. This paper describes the work - undertaken with different technological systems that have potential for pedestrian location sensing connecting the pedestrian user with real and virtual environments simultaneously. In particular we look at how users can be correctly located and efficiently informed about buildings and artefacts that are part of the spectrum of built forms that together are referred to as Architectural Heritage sites.

title	A Prototype Using Multi-Agent Based Simulation in Spatial Analysis and Planning
source	Proceedings of the 14th International Conference on Computer Aided Architectural Design Research in Asia / Yunlin (Taiwan) 22-25 April 2009, pp. 513-521
doi	https://doi.org/10.52842/conf.caadria.2009.513
summary	Pedestrian’s movements and spatial cognition in urban environments are main issues for urban designers in urban spatial planning and analysis. This paper aims to study interactions between a behavioural model of pedestrians and urban spaces. The pedestrians can be represented by an agent program, and behavioural reactions of walking agents under different stimulus can be further simulated. Thus, this study suggests that, a correlation study on pedestrian behaviours and spatial environments become the criterion for urban designers in order to help them create better flows.

summary	This paper aims to study interactions between a behavioral model of pedestrians and urban spaces, and regards micro-scale urban spaces as its target. This paper suggests constructing and analyzing a pedestrian behavioral model using the “Attention Theory”, and introducing the rules and attributes of agent behavior oriented simulation. Based on the validation of actual street cases, the findings show that the pedestrians can be represented by an agent program, and behavioral reactions of walking agents under different stimulus can be further simulated.

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

title	On the simulation of pedestrian behavior: A stochastic model based on Markov chain and information space
source	T. Tidafi and T. Dorta (eds) Joining Languages, Cultures and Visions: CAADFutures 2009, PUM, 2009, pp. 861- 874
summary	Pedestrians move according to their internal states and the spatial information that they perceive at their locations. We use Markov chain to define the state transition of a pedestrian as a stochastic process, and the concept of cellular automata to simulate the way information disseminates in space. We have implemented an agent-based computer program to observe some emergent behaviors from the interactions between pedestrians and the information space they are surrounded. It is expected that the representational model can be used to assist designers in analyzing the relation between building plan and the circulation pattern.

title	Interactive Hemostasis Modeling in Urban Network Design
source	International Journal of Architectural Computing vol. 7 - no. 3,375-387
summary	This paper describes a type of project that images a city as it might exist given the integration of hemostatic procedures within pedestrian networks during emergencies requiring full-scale egress from an urban core. It articulates the steps taken to integrate a pre-existing C++ hemostasis model (C. Jacob, 2008) into Maya software in order to describe how the project operates on a computational level. By projecting these agent-based logics directly into/onto each pedestrian in the city (the smallest unit of the system), egress-oriented infrastructure can shift from being extensively predetermined in form (concrete barriers, metal railing, police barricades, etc.), to something more intensively defined, real-time, and locally on-demand. These procedures are situated within a larger schema based on the structural principles of Norbert Wiener's cybernetic feedback loops, that acknowledge and allow for hybrid (top-down + bottom-up) awareness and control within systems. The project attempts to ally itself with emerging forms of network design with similar structural typologies supported through the use of personal mobile devices (PMDs) in urban environments.

summary	Collaboration is essential to the kind of innovative, revolutionary, game-changing innovations necessary to improve our world. Oswall is a collaborative construction system that endeavors to leverage collaboration to make a game-changing leap forward. Oswall (Open Source Wall) is an experimental wall prototype that challenges conventional residential wall construction through an open, collaborative approach to material, fabrication, and installation methods. It proposes an “open source” construction platform in which third-party designers, engineers, scientists, or “do-it-yourselfers” can create, produce, market, and sell “applications” that are plugged into the wall.

summary	Design considers function, fabrication, and aesthetics collectively. Computation is beginning to affect the competitive dynamics of design. Using algorithms, designers are exploring forms that are essentially “undrawable,” even with advanced modeling and direct manipulation techniques. Determining the appropriate functional characteristics may require the application of increasingly complex structural- and environmental-performance analysis techniques. To realize physically a design may require further geometric analysis and rationalization, and the use of complex computer-controlled fabrication techniques.

summary	We will address the challenges of design information in designing interfaces and functional dynamics considering a content part of the collaboration of users whose commitment to the project reaches various levels. The use of a well-structured iconography and the availability of help, shortcuts and tutorials are some of the resources already exploited, however, there is still room for reflection on the use of visuals and sounds aimed at facilitating the navigability on such projects. Here are some important details that must be considered by examining models of existing applications.

summary	The Cooperative Design Environment Laboratory (CoDE Lab) is carrying out a research with students, trainees and seniors who have previously participated to CAAD-assisted design courses. These courses were developed with the aim of making participants independent from the pre-analytical phase project to the renderings of the final artifact. The programs that have been used so far are Autodesk Revit, Graphisoft Archicad and Nemetschek Allplan.The teaching workgroup has always believed that analyzing, deconstructing and reconstructing the architecture teaches much in terms of understanding. If the process is done correctly, it entirely re-traces the creative dynamics developed by the original designer. Subsequently, the educational practice is to choose a notable architectural work, designed and/or created by a Master of architecture, and to reproduce it in all details: aesthetical-formal, morphological, technological, structural, modular, etc. The final result is an archive of well-developed reconstructed models of great specific interest. The students on the other hand thoroughly learn how to control the tools and all BIM planning procedures.

summary	In experimenting with digital processes for simulating the behavior of tension-active cable nets, a method was developed for creating informed geometries by utilizing computational meshes that carry properties of structure, space, and material. A spring-based particle system provided the dynamics to simulate the flow of tension force through the geometry. Particular functions were scripted to embed logics for fabrication and analysis of spatial parameters. This formulated a lightweight, reactive design tool for which multiple cable net morphologies could be quickly generated. This paper will describe the experiments in creating the method to generate such cable net morphologies, and discuss the potential application for this computational framework to apply to other architectural systems.

summary	This paper will relay the initial phase of a collaborative work within partners from the design discipline, systems engineering, and software engineering which deals with the interrelations of “network idea”, “systems thinking”, “collective design”, and “computation”. Vensim– a system dynamics modelling tool developed by Ventana Systems, Inc. in 1992 – has been used in an experimental first year design studio to engage students in systems thinking in the architectural design environment. It has been observed that this tool enabled most students to develop a multi-layered, complex and more controlled design logic and to amplify the cognitive processes at the beginning of the design education. We conclude that in order to fully realize systems thinking in the design process, new ways of integrating parametric design environments and system dynamic modelling environments needs to be investigated.

title	Computational Fluid Dynamics in Building Design Practice

doi	https://doi.org/10.52842/conf.acadia.2020.1.574
summary	This paper provides a state-of-the-art of computational fluid dynamics (CFD) in the building industry. Two methods were used to find this new knowledge: a series of interviews with leading architecture, engineering, and software professionals; and a series of tests in which CFD software was evaluated using comparable criteria. The paper reports findings in technology, workflows, projects, current unmet needs, and future directions. In buildings, airflow is fundamental for heating and cooling, as well as occupant comfort and productivity. Despite its importance, the design of airflow systems is outside the realm of much of architectural design practice; but with advances in digital tools, it is now possible for architects to integrate air flow into their building design workflows (Peters and Peters 2018). As Chen (2009) states, “In order to regulate the indoor air parameters, it is essential to have suitable tools to predict ventilation performance in buildings.” By enabling scientific data to be conveyed in a visual process that provides useful analytical information to designers (Hartog and Koutamanis 2000), computer performance simulations have opened up new territories for design “by introducing environments in which we can manipulate and observe” (Kaijima et al. 2013). Beyond comfort and productivity, in recent months it has emerged that air flow may also be a matter of life and death. With the current global pandemic of SARS-CoV-2, it is indoor environments where infections most often happen (Qian et al. 2020). To design architecture in a post-COVID-19 environment will require an in-depth understanding of how air flows through space.

title	Unified Energy-Based Qualitative Representation for Building Analysis
source	in J McDonnell and P Lloyd (eds), About: Designing. Analysing Design Meetings, CRC Press, pp. 213-229.
summary	Currently, when designers develop a building design project, different representations are used for different building subsystems, such as spatial system, electrical system, lighting system, hydraulic system and HVAC. These representations are mainly used in the final design documentation stage. This book presents a qualitative approach to the development of a unified energy-based representation for building analysis called qualitative Archi Bond Graphs (QABGs). QABGs integrate different representations in the architectural domain into a unified representation. They can be applied in the conceptual, intermediate, and final building design stages. Combining graphical representations and qualitative equations, QABGs are applicable for building simulation and analysis for building dynamics in the space-people system and the building energy systems, and for energy interactions between the space-people system and the building energy systems.
