title	An Ontology-Based Template of User-Actor to Support Agent-Based Simulation in Built Environments
source	CAAD \| INNOVATION \| PRACTICE [6th International Conference Proceedings of the Arab Society for Computer Aided Architectural Design (ASCAAD 2012 / ISBN 978-99958-2-063-3], Manama (Kingdom of Bahrain), 21-23 February 2012, pp. 171-179
summary	The behavior of a human being in a building, its activities, its interactions with it and with other people are certainly a highly complex phenomenon extremely hard to predict and evaluate. At the same time, the response of a built environment to future users’ needs is one of the key factors of its performance. The Agent-based Modeling paradigm is considered potentially the best way to represent human behavior but, in the building design field, its experiences are limited to representation of partial aspects of human behavior in discrete events. Currently, a more "extended" representation of human behavior able to offer an overview of the human activities related to the building ‘functioning’, is missing,. This lack is due to the complexity of interaction among users and built environment, and to the extensive knowledge, provided by different disciplines, needed to reliably represent it. The proposed research focuses on the construction of a general representation template of user-actor, easy to implement and flexible enough to structure the large amount of data affecting human behavior. The development of the ontology-based template shown in this paper can lead to a user-agent’s entity whose parameters and behavioral rules can encode and represent several ‘aspects’ of real users and their interactions with the other entities (building components, furniture, other people) in a built environment.

title	Agent-Based Social Pedestrian Simulation for the Validation of Urban Planning Recommendations
source	SIGraDi 2012 [Proceedings of the 16th Iberoamerican Congress of Digital Graphics] Brasil - Fortaleza 13-16 November 2012, pp. 332-336
summary	The goal of this project is a deeper understanding of the mechanisms that shape a city with a focus on pedestrian flow. Pedestrian flow reveals the use of space, the capacity and use of transportation and has an impact on the health of people. Movement patterns of pedestrians are a topic in many related fields like transportation planning, computer graphics and sociology. This project augments the simulation of pedestrian decision processes by taking into account the preferences for surrounding factors like additional points of interests and how pedestrians interact along their path with other pedestrians in a social manner. The goal of this project is to analyse urban planning configurations and to give designers and decision makers a tool to measure the amount of people walking and therefore define the health of a society, finding places of social interaction and improving social coherence in neighbourhoods.

title	Performative Topologies: An Evolutionary Shape Optimization Framework for Daylighting Performance Coupling a Particle-Spring System With an Energy Simulation Tool
doi	https://doi.org/10.52842/conf.acadia.2012.479
source	ACADIA 12: Synthetic Digital Ecologies [Proceedings of the 32nd Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-1-62407-267-3] San Francisco 18-21 October, 2012), pp. 479-490
summary	This paper develops a methodological approach for use in design practice which combines an external simulation tool (EnergyPlus™) with an evo-lutionary optimisation strategy for the form-finding of complex fenestra-tion systems. On one hand, based on previous research, it presents a novel approach for the shape morphogenesis that exploits a generative algorithm technique to control a limited set of parameters whilst on the other hand it facilitates the integration of a simulation tool capable of handling increasing levels of complexity with greater data interoperabil-ity. In doing so it will argue the heuristic potential of the proposed meth-od in aiding the designers’ decision making whilst increasing the formal possibilities of their final design solutions.

source	SIGraDi 2012 [Proceedings of the 16th Iberoamerican Congress of Digital Graphics] Brasil - Fortaleza 13-16 November 2012, pp. 458-461
summary	This paper presents the results of an exploratory study developed with the Autodesk Project Vasari and AutoCAD Civil 3D. Project Vasari was used to evaluate the environmental performance of a low-income housing project. It shows us that the actual site orientation of the project presents poor environmental performance, which could be improved by rotating building in 90 degrees. The AutoCAD Civil 3D was used to evaluate how that rotation should impact on earthmoving. The results showed that the simulations developed, even though having low level of accuracy, provide sufficiently clear information to support decision making on conceptual mass project stage.

summary	During building design processes, designers have to predict and evaluate future building performances oriented to its intended use and users. Current BIM and IFC technologies support designers allowing data exchange and information interoperability but, since their lack in semantics, they don’t provide any knowledge implementation about how the designed building will be actually used and how people will interact with it. The research described in this paper aims to overcome this shortcoming by developing a new modelling approach, oriented to representation and management of knowledge related to future building use and users. The proposed representation model is based on an already accepted ontology-based structure and will make this large amount of knowledge accessible and usable by designers during architectural design processes, in order to enhance the final quality of the design product.

title	Progress Towards Multi-Criteria Design Optimisation Using Designscript With Smart Form, Robot Structural Analysis and Ecotect Building Performance Analysis"
doi	https://doi.org/10.52842/conf.acadia.2012.047
source	ACADIA 12: Synthetic Digital Ecologies [Proceedings of the 32nd Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-1-62407-267-3] San Francisco 18-21 October, 2012), pp. 47-56
summary	Important progress towards the development of a system that enables multi-criteria design optimisation has recently been demonstrated during a research collaboration between Autodesk’s DesignScript development team, the University of Bath and the engineering consultancy Buro Happold. This involved integrating aspects of the Robot Structural Analysis application, aspects of the Ecotect building performance application and a specialist form finding solver called SMART Form (developed by Buro Happold) with DesignScript to create a single computation environment. This environment is intended for the generation and evaluation of building designs against both structural and building performance criteria, with the aim of expediently supporting computational optimisation and decision making processes that integrate across multiple design and engineering disciplines. A framework was developed to enable the integration of modeling environments with analysis and process control, based on the authors’ case studies and experience of applied performance driven design in practice. This more generalised approach (implemented in DesignScript) enables different designers and engineers to selectively configure geometry definition, form finding, analysis and simulation tools in an open-ended system without enforcing any predefined workflows or anticipating specific design strategies and allows for a full range of optimisation and decision making processes to be explored. This system has been demonstrated to practitioners during the Design Modeling Symposium, Berlin in 2011 and feedback from this has suggested further development.

title	Edible Infrastructures: Emergent Organizational Patterns for the Productive City
doi	https://doi.org/10.52842/conf.acadia.2012.511
source	ACADIA 12: Synthetic Digital Ecologies [Proceedings of the 32nd Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-1-62407-267-3] San Francisco 18-21 October, 2012), pp. 511-526
summary	Edible Infrastructures is an investigation into a projective mode of urbanism which considers food as an integral part of a city's metabolic infrastructure. Working with algorithms as design tools, we explore the generative potential of such a system to create an urban ecology that: provides for its residents via local, multi-scalar, distributed food production, reconnects urbanites with their food sources, and de-couples food costs from fossil fuels by limiting transportation at all levels, from source to table. The research is conducted through the building up of a sequence of algorithms, beginning with the ‘Settlement Simulation’, which couples consumers to productive surface area within a cellular automata type computational model. Topological analysis informs generative operations, as each stage builds on the output of the last. In this way we explore the hierarchical components for a new Productive City, including: the structure and programming of the urban circulatory network, an emergent urban morphology based around productive urban blocks, and opportunities for new architectural typologies. The resulting prototypical Productive City questions the underlying mechanisms that shape modern urban space and demonstrates the architectural potential of mathematical modeling and simulation in addressing complex urban spatial and programmatic challenges.

summary	This paper discusses the potential of emerging digital representations of built environments coupled with agent-based modelling (ABM). A new set of urban transportation data is provided as an input which is the electric vehicles (EVs) population of one of the UK metropolitan areas. The study is a part of a PhD research that focuses on investigating computer-aided software to develop a virtual route for electric mobility in the North Sea Region. An overview of agent-based simulation platforms is discussed. Electric mobility system has particular paradigms that differ from conventional urban transport systems; a comparison is presented followed by the recommended approach of integrating the two techniques (visualization and simulation). Finally, the architecture of agents’ algorithm within the EVs network is presented through a case study of virtual Newcastle-Gateshead model.

title	Emergent Reefs
doi	https://doi.org/10.52842/conf.acadia.2012.139
source	ACADIA 12: Synthetic Digital Ecologies [Proceedings of the 32nd Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-1-62407-267-3] San Francisco 18-21 October, 2012), pp. 139-148
summary	The Emergent Reefs project thrives on the potential that emerge from a coherent utilization of the environment’s inherent ecological structure for its own transformation and evolution, using an approach based on digitally simulated ecosystems and sparkled by the possibilities and potential of large-scale 3D printing technology. Considering tourism as an inevitable vector of environmental change, the project aims to direct its potential and economic resources towards a positive transformation, providing a material substrate for the human-marine ecosystem integration with the realization of spaces for an underwater sculpture exhibition. Such structures will also provide a pattern of cavities which, expanding the gradient of microenvironmental conditions, break the existing homogeneity in favor of systemic heterogeneity, providing the spatial and material preconditions for the repopulation of marine biodiversity. Starting from a digital simulation of a synthetic local ecosystem, a generative technique based on multi-agent systems and continuous cellular automata (put into practice from the theoretical premises in Alan Turing’s paper “The Chemical basis of Morphogenesis” through reaction-diffusion simulation) is implemented in a voxel field at several scales giving the project a twofold quality: the implementation of reaction diffusion generative strategy within a non-isotropic 3-dimensional field and integration with the large-scale 3D printing fabrication system patented by D-Shape®. Out of these assumptions and in the intent of exploiting the expressive and tectonic potential of such technology, the project has been tackled exploring voxel-based generative strategies. Working with a discrete lattice eases the simulation of complex systems and processes across multiple scales (including non-linear simulations such as Computational Fluid-Dynamics) starting from local interactions using, for instance, algorithms based on cellular automata, which then can be translated directly to the physical production system. The purpose of Emergent-Reefs is to establish, through strategies based on computational design tools and machine-based fabrication, seamless relationships between three different aspects of the architectural process: generation, simulation and construction, which in the case of the used technology can be specified as guided growth.

title	Availability of a distributed and synchronised type meeting by using cloud computing type VR for spatial design study
doi	https://doi.org/10.52842/conf.caadria.2012.203

summary	The mobility of people's activities, and cloud computing technologies are becoming advanced in the modern age of information and globalisation. This study describes the availability of discussing spatial design while sharing a 3-dimensional virtual space with stakeholders in a distributed and synchronised environment. First of all, a townscape design support system based on a cloud computing type VR system is constructed. Next, an experiment of a distributed and synchronised discussion of townscape design is executed with subjects who are specialists in the townscape design field. After the experiment, both qualitative mental evaluation and quantitative evaluation were carried out. The conclusions are as follows: 1. Users who use VR frequently and who use videoconferencing consider that the difference with face-to-face discussion is small. 2. A Moiré pattern may occur in a gradation picture. 3. The availability of distributed and synchronised discussions with cloud computing type VR is high.

title	Computational Design of Robotically Manufactured Plate Structures Based on Biomimetic Design Principles Derived from Clypeasteroida

summary	The paper presents the current development of an ongoing research project about the integration of robotic fabrication strategies in computational design through morphological and functional principles derived from natural systems. Initially, a developed plate structure material system based on robotically fabricated fi nger joints is being informed by biomimetic principles from the sea urchin Clypeasteroida in order to be able to adapt effi ciently to its building environment. Consequently, the paper’s main focus lies on translating the biomimetic design principles into a computational design tool, also integrating fabrication parameters as well as structural and architectural demands. The design tool’s capability to integrate these parameters is shown by the design, development and realization of a full-scale research pavilion. The paper concludes with discussing the performative capacity of the developed material system and the introduced methodology.

summary	In this paper we propose an open source design tool that allows designers to easily conceive, evaluate and design the full auditory experience of a building, based on a digital three-dimensional model. A guiding principle has been the dynamic nature of the confi guration of sound sources and listeners. Hence, a system is created that enables sound sources as well as listeners to be defi ned as moving entities. Furthermore, the ability exists for listeners, in their own movements and interactions, to generate sounds as well. In the system, proposed in this paper, ray-tracing is used to simulate the spatial acoustics. The paper discusses the considerations regarding several implementation choices and regarding adoption of the tool in the architectural design process.

title	An IFC based design check approach for the optimisation of material efficiency in the built environment
doi	https://doi.org/10.52842/conf.caadria.2012.275
source	Proceedings of the 17th International Conference on Computer Aided Architectural Design Research in Asia / Chennai 25-28 April 2012, pp. 275–284
summary	Compared to other industries, the built environment is still the largest and one of the least efficient consumers of resources. Existing measures and procedures for resource recovery and reuse are focused on the demolition phase, when the composition of materials and structures is mostly unknown and hard to be analysed. Therefore, these measures are somewhat inefficient for overall high-rate material recovery. The enhancement of the integrated semantic planning process by the introduction of the IFC unified data standard and BIM technology is a first-time opportunity to track, analyse, document and simulate all relevant players, parameters and processes with an impact on the resource and material efficiency through the entire life cycle of a building in the design phase of a building project. The presented work explores the potential of IFC to serve as a framework for achieving a higher material efficiency in the built environment. A proposed design check approach for the simulation and optimisation of material efficiency in a building over its life cycle is based on a system of key parameters and actions organised in logic trees. The parameters and actions are translated into IFC objects. Additionally required IFC objects and properties are identified and described.

summary	Digital Vernacular investigates the potential of the process of depositing a paste like material with precision using a CNC device which has produced an innovative system for design and fabrication of environmentally responsive housing. Architectural practice has been greatly impacted by technical innovations in the past, usually new building types emerge as part of new ideologies. Yet the current revolution in computer-aided design and fabrication has architecture focusing on form – without questioning what these new processes can bring for the masses. The research project 'Digital Vernacular' has investigated the potential of using CNC technology for the production of housing. It has focused on the design of the machinic devices as well as computational design tools, and revolves around the concept of fabrication on site. Using an additive and layered manufacturing process and locally available material, the project proposes a revolutionary new digital design and fabrication system that is based on one of the oldest and most sustainable construction methods in the world. The main potentials of this method are not to create complex forms for the sake of design, but to use parametric control to adapt each design to the specificities of its site. Using geometrical rules found during many research experiments with real material behaviour, a new architectural language is created that merges several environmental functionalities into a single integrated design.

summary	An exploration study is performed to investigate how a dynamic (digital) structural expressivity can lead to a new intuitive relationship between the individual user and the building.The study links the structure’s experience which can be described mathematically, and is theoretically exact, to the subjective user’s experience that is studied in the fi eld of psychology and phenomenology. The dynamic nature of their interaction is studied and an interactive virtual design is made in which the structure shows the forces the user introduces and also adapts to them; it enables intuitive communication. This approach fi ts in the global shift from primarily static to a more dynamic, one to one, agent based understanding of our environment.

title	Kinetic Hybrid Structure Development and Simulation
source	International Journal of Architectural Computing vol. 10 - no. 1, 67-86
summary	Supported through technological advances, the concept of kinetic architecture is internationally increasingly acknowledged in the past years in the development of adaptable buildings as to differing functional requirements, or external loading conditions. Most decisive factor is the structure in terms of materials and geometrical configurations, and the control system integrated within. Based on general principles of tensegrity structures, a hybrid system has been developed that consists of continuous hinge connected compression members, strengthened by an internal system of struts and continuous cable diagonals with closed loop. The kinetic mechanism is achieved through alteration of the cables length and the respective relative inclination of any adjacent compression members. In this way the transformability of the system arises primarily from the inherent integrative composition and dual capabilities of its members. Following the construction design of the prototype structure, the interactive development, as regards geometric properties and structural configurations, is presented analytically, as based on a parametric-associative design approach applied. Along this line, the specific syntax of structural development and simulation through parametric design is suggested to support in real terms the control design of the innovative structure in an integrated interactive context.

summary	Sketches and working models are without doubt one of the most widely used tools in the architect’s repertoire. In the early phases of the design process in particular, they represent an essential part of the exploration process. For the most part, however, sketching and model building are separate and sequential steps. This paper examines how both media can be linked to each other more effectively so that the design process is more continuous and the transition between the two media more fluid. Using a multi-touch table with additional 3D real-time object recognition, a prototypical system was developed and realised as part of a research project in which an interactive 3D sketching tool was linked with a real 3D working model.
