summary	The Hylomorphic Project is a complex canopy structure, genetically evolved as a vital entity that reacts to changing data streams while configuring the architectural form. For the Hylomorphic Project, Open Source Architecture (OSA) together with structural engineer Prof. Kristina Shea and Marina Gourtovaia of Cambridge University (UK) developed genetic algorithms. Performs in eifForm software, an experimental computer-aided design system for structural synthesis, the algorithm is based in computational environments as a methodology for form finding and material expression that goes beyond the formal articulation of the computational procedure. This procedure simulates a topological condition of natural form evolution that can be consolidated according to innumerable trajectories. Seeking dynamic, flexible and continuous evolution procedures, the software provides the required conditions for this type of the design as it consists of a computational core, which is written in C, a fast low-level compiled language. The modules providing interactive access to the core and the graphical user interface (GUI), a high-level scripting language written in Python, allow for easy customization of the software according to a design task in hand.

title	Bidirectional Interoperability Between CAD and Energy Performance Simulation Through Virtual Model System Framework
doi	https://doi.org/10.52842/conf.acadia.2006.232
source	Synthetic Landscapes [Proceedings of the 25th Annual Conference of the Association for Computer-Aided Design in Architecture] pp. 232-250
summary	The paper describes a novel approach involving interoperability, data modeling technology, and application of the building information model (BIM) focused on sustainable architecture. They share relationships and multiple experiences that have existed for years but have never have been proven. This interoperability of building performance simulation maps building information and parametric models with energy simulation models, establishing a seamless link between Computer Aided Design (CAD) and energy performance simulation software. During the last four decades, building designers have utilized information and communication technologies to create environmental representations to communicate spatial concepts or designs and to enhance spaces. Most architectural firms still rely on hand labor, drafted drawings, construction documents, specifications, schedules and work plans in traditional means. 3D modeling has been used primarily as a rendering tool, not as the actual representation of the project.With this innovative digitally exchange technology, architects and building designers can visually analyze dynamic building energy performance in response to changes of climate and building parameters. This software interoperability provides full data exchange bidirectional capabilities, which significantly reduces time and effort in energy simulation and data regeneration. Data mapping and exchange are key requirements for building more powerful energy simulations. An effective data model is the bidirectional nucleus of a well-designed relational database, critical in making good choices in selecting design parameters and in gaining and expanding a comprehensive understanding of existing data flows throughout the simulation process, making data systems for simulation more powerful, which has never been done before. Despite the variety of energy simulation applications in the lifecycle of building design and construction projects, there is a need for a system of data integration to allow seamless sharing and bidirectional reuse of data.

title	SCALE - A street case library for environmental design with agent interfaces
source	Van Leeuwen, J.P. and H.J.P. Timmermans (eds.) 2006, Innovations in Design & Decision Support Systems in Architecture and Urban Planning, Dordrecht: Springer, ISBN-10: 1-4020-5059-3, ISBN-13: 978-1-4020-5059-6, p. 137-150
summary	Urban space provides a context for human interaction. Recently, urban planning has largely placed the user at the street as the centre of infrastructural design, with significant implications for the perceived attractiveness of user environments. However, visual observation is often difficult for verifying planning goals. The simulation of pedestrian behaviour is important for physical planning, but such research is scarce. In this study, we adopt an empirical approach for generating reactive path following. Further, we implement scenarios as computer scripts with agent-based interfaces to identify navigational patterns. Moreover, we built a hierarchy of individual behavioral models and define a behavior production system to control the agent. Key attributes of streets such as rest space, utilities, landmarks, and buildings have space tags as identifiers to associate streets with related activities.

summary	The choice of a chord and its execution should be regarded as a must and not left to arbitrary wish or superficial speculation. (Johannes Itten, 1961) The paper describes a modular concept for the IT-support of planning practice using BIM (Building Information Modelling) and a parameterized building model. The platform used is the modularized software concept for architectural planning in existing built contexts (prototype software FREAK). The current progress in the development of a reasoned support of planning tasks is described in this paper in more detail. The system consists of a series of software prototypes which are linked to the BIM, utilize the specific data within and demonstrate the value of a consistent and extendable CAD-model. The “Colored Architecture” software prototype is one such design-support module of the software platform and enables the designer to experiment with the parameters colour, light and materials in architectural space. This module supports experimentation, assessment and realization of colours and materials in the architectural design process on a new quality. For instance, the integration of “live radiosity” light simulation allows a qualified and interactive assessment and evaluation of colours and materials in near-real lighting conditions. The paper also details further software prototypes, modules and concepts including building surveying and the design of self-supporting domed structures.

summary	The perception of space, geometry, material and the influence of light is one of the core items of undergraduate courses in architecture. In Bochum we developed and still practise a consequent system of integrating drawing and photography as analytic tools of perception and sketching, descriptive geometry, computer aided design, digital visualisation and animation as synthetic items. The versatile use of digital media in the further studies is of essential significance - especially the synthesis between architectural photography (with all its special features concerning geometrical depicting) and CAD / visualisation / animation. Special emphasis is given to techniques for simulation and immersion such as digital panorama photography, combined with computer-based vr-modelling e.g. vrml as well as using online-cad-modeling and arial photography in processes of citizen participation.

title	Approach to Design Behavioural Models for Traffic Network Users - Choice of transport mode
source	Van Leeuwen, J.P. and H.J.P. Timmermans (eds.) 2006, Innovations in Design & Decision Support Systems in Architecture and Urban Planning, Dordrecht: Springer, ISBN-10: 1-4020-5059-3, ISBN-13: 978-1-4020-5059-6, p. 151-166
summary	Our research work concerns the development of a multimodal urban traffic simulator designed to be a tool of decision-making aid similar to a game wherein the user-player can test different scenarios by immersion in a 3D virtual city. Our approach is based on the activity-based model and the multi-agent technology. The implemented result is a hybrid simulator connecting numerical simulation and behavioural aspects coming from real data. This paper is focused on two points: firstly, we introduce how a final user (the traffic regulator) instantiates and assembles components so as to model a city and its urban traffic network; secondly, we present the use of Dempster-Shafer theory in the context of discrete choice modelling. Our approach manipulates input variables in order to test realistic representations of behaviours of agent categories in a decision-making process. The traffic modelling is based on a questionnaire elaborated from standard arrays of Taguchi. The significant variables and interactions are determined with the analysis of variance which suggests a reduced model describing the behaviour of a particular social category. The belief theory is used to take into account the doubt of some respondents as well as for the preferences redistribution if the number of alternatives changes. The effects of external traffic conditions are also quantified to choose a 'robust' alternative and to use the agents' memory.

summary	In recent years there has been a demand that local residents take part in the planning of environmental designs from the initial stages. On the issue of understanding the local environment, it is desirable to accumulate and share information and to enable it to be reused. To this end, attention has been focused on the cellular phone which can provide position information and picture information in addition to serving as a tool of general communication. For several years now it has been increasingly common for cellular phones to be equipped with an E-mail function, a web browsing function, a camera function, a GPS function, etc. Using such cellular phones, it will become possible to quickly accumulate local information with detailed picture information and position information. On the other hand, it is desirable to look at and understand an environment interactively from various points of view from the initial stage of a project. For that purpose, examination using 3D space which makes real-time simulation possible is required. In this research, using a cellular phone with a GPS camera, scene image data is collected with the aim of constructing a local scene evaluation system which can perform a picture display using a 3D space model.

doi	https://doi.org/10.52842/conf.ecaade.2006.128
source	Communicating Space(s) [24th eCAADe Conference Proceedings / ISBN 0-9541183-5-9] Volos (Greece) 6-9 September 2006, pp. 128-131
summary	This paper describes a procedure that feeds remotely a modelling system with geographical coordinates and the relative measurements taken in place in order to model dynamically new entities in real-time. The operation of this system is based on methodologies that are commonly used in telegeoprocessing – telegeomonitoring systems and its purpose is to simulate in real-time an existing environment using the captured measurements. The direct input of geographic data to the proposed system, which is adapted to a modelling environment (CAD or GIS), triggers the creation of new 3D entities in real-time (points, linear or area features), as it could be done with a traditional tablet digitizer. Simultaneously, the proposed system represents thematically the properties of the modelling entities (according to the measured values) over a 3D mesh. The aim of the suggested system is the remote registration of additional spatial information, their adequate treatment and adjustment via special developed interfaces, including their representation via developed software which is applied in the AutoCAD environment because of its programming development support and its use by a variety of engineers.

title	A Real-Time Simulation Tool for Fault Detection and Diagnosis of HVAC Systems
source	Computing in Architecture / Re-Thinking the Discourse: The Second International Conference of the Arab Society for Computer Aided Architectural Design (ASCAAD 2006), 25-27 April 2006, Sharjah, United Arab Emirates
summary	In this study, a real-time simulation tool was developed for online monitoring, control and diagnosis of HVAC systems. A twozone variable air volume terminal reheat (VAV-TRH) HVAC system is considered. The developed program can be used in offline and online environments. The offline environment allows the operators to examine optimal control strategies, and to investigate problems associated with improper size of components which could be the root cause of the fault. The online environment is useful for monitoring, control and diagnosis of HVAC systems. A set of expert rules were applied to identify the faults. Simulation results show that the developed tool is able to correctly identify the fault patterns and therefore can be used for improving operating performance of HVAC systems.

summary	The current research deals with the development of an Activity-Based Multi Agent System fully implemented in a G.I.S. framework and applied to the case study of the historical centre of Pisa. The objective is to create a simulation tool for Pisa population transfers in order to verify how transport demand varies because of interventions on traffic plan (e.g. creating urban areas subject to a toll access for vehicles), or on public transport lines, or on new activities location (e.g. supermarkets, public services etc.). Three different parts of the System have been simultaneously carried out: the first concerns a population sample survey, the second deals with geographical data structuring and the last one, still in elaboration progress, tests the model reliability to estract and implement behavioural rules. The results obtained till now show how the Database itself, containing temporal data about agents activities (extracted by the population sample questionnaire) and urban services the city offers, already represents an important instrument to support decision making process.

title	Supporting Collective Intelligence for Design in Virtual Worlds: A Case Study of the Lego Universe
source	Computer Aided Architectural Design Futures 2011 [Proceedings of the 14th International Conference on Computer Aided Architectural Design Futures / ISBN 9782874561429] Liege (Belgium) 4-8 July 2011, pp. 637-652.
summary	Virtual worlds are multi-faceted technologies. Facets of virtual worlds include graphical simulation tools, communication, design and modelling tools, artificial intelligence, network structure, persistent object-oriented infrastructure, economy, governance and user presence and interaction. Recent studies (Merrick et al., 2010) and applications (Rosenman et al., 2006; Maher et al., 2006) have shown that the combination of design, modelling and communication tools, and artificial intelligence in virtual worlds makes them suitable platforms for supporting collaborative design, including human-human collaboration and human-computer co-creativity. Virtual worlds are also coming to be recognised as a platform for collective intelligence (Levy, 1997), a form of group intelligence that emerges from collaboration and competition among large numbers of individuals. Because of the close relationship between design, communication and virtual world technologies, there appears a strong possibility of using virtual worlds to harness collective intelligence for supporting upcoming ‚Äúdesign challenges on a much larger scale as we become an increasingly global and technological society‚Äù (Maher et al, 2010), beyond the current support for small-scale collaborative design teams. Collaborative design is relatively well studied and is characterised by small-scale, carefully structured design teams, usually comprising design professionals with a good understanding of the design task at hand. All team members are generally motivated and have the skills required to structure the shared solution space and to complete the design task. In contrast, collective design (Maher et al, 2010) is characterised by a very large number of participants ranging from professional designers to design novices, who may need to be motivated to participate, whose contributions may not be directly utilised for design purposes, and who may need to learn some or all of the skills required to complete the task. Thus the facets of virtual worlds required to support collective design differ from those required to support collaborative design. Specifically, in addition to design, communication and artificial intelligence tools, various interpretive, mapping and educational tools together with appropriate motivational and reward systems may be required to inform, teach and motivate virtual world users to contribute and direct their inputs to desired design purposes. Many of these world facets are well understood by computer game developers, as level systems, quests or plot and achievement/reward systems. This suggests the possibility of drawing on or adapting computer gaming technologies as a basis for harnessing collective intelligence in design. Existing virtual worlds that permit open-ended design ‚Äì such as Second Life and There ‚Äì are not specifically game worlds as they do not have extensive level, quest and reward systems in the same way as game worlds like World of Warcraft or Ultima Online. As such, while Second Life and There demonstrate emergent design, they do not have the game-specific facets that focus users towards solving specific problems required for harnessing collective intelligence. However, a new massively multiplayer virtual world is soon to be released that combines open-ended design tools with levels, quests and achievement systems. This world is called Lego Universe (www.legouniverse.com). This paper presents technology spaces for the facets of virtual worlds that can contribute to the support of collective intelligence in design, including design and modelling tools, communication tools, artificial intelligence, level system, motivation, governance and other related facets. We discuss how these facets support the design, communication, motivational and educational requirements of collective intelligence applications. The paper concludes with a case study of Lego Universe, with reference to the technology spaces defined above. We evaluate the potential of this or similar tools to move design beyond the individual and small-scale design teams to harness large-scale collective intelligence. We also consider the types of design tasks that might best be addressed in this manner.

title	Shape Morphing of Intersection Layouts Using Curb Side Oriented Driver Simulation
source	Van Leeuwen, J.P. and H.J.P. Timmermans (eds.) 2006, Innovations in Design & Decision Support Systems in Architecture and Urban Planning, Dordrecht: Springer, ISBN-10: 1-4020-5059-3, ISBN-13: 978-1-4020-5059-6, p. 167-183
summary	In a traffic network, capacities of parts of the network restrict the amount of transport that can be handled by this network. The capacity of a given traffic network element is not fixed, but influenced by parameters such as number of lanes, maximum speed, weather, view horizon, and so on. These parameters also define the maximum capacity of complicated intersections. Special shapes of intersections, particularly in urban regions, may further increase or decrease their capacity. This paper investigates an evolutionary algorithm to automatically improve the geometrical layout of parts of an urban network according to externally specified criteria. The paper consists of two main parts. In the first part, a simulation model is described which is able to produce realistically behaving vehicles only by using information about the curb side locations of the roads. This avoids the need to use lane connectivity, signal plans, etc. - which are details that would change during a change of the intersection layout. In the second part of the paper, the simulation changes the road and intersection layouts based on the behaviour of the vehicles. Using a feedback loop allows one to optimize the capacity of the modelled road system while its spatial extents are minimized. As a case study, a special roundabout is examined: 'Central' in downtown Zurich, Switzerland. The particularity of this roundabout is that it partially behaves like a roundabout but also contains two uncontrolled intersections. Due to its central position in the city, the roundabout is very busy with both individual cars and public transport vehicles.

source	Van Leeuwen, J.P. and H.J.P. Timmermans (eds.) 2006, Innovations in Design & Decision Support Systems in Architecture and Urban Planning, Dordrecht: Springer, ISBN-10: 1-4020-5059-3, ISBN-13: 978-1-4020-5059-6, p. 359-374
summary	In general the Urban Decision Room is an interactive computer system based around a digital model for the simulation of complex urban decision questions. Such questions involve various parties with often differing interests. The UDR can assist in finding collective solutions. The UDR is a useful instrument for making the great variety in interests and ideas of the participants manageable. Furthermore, insight is quickly and clearly provided into the results. This enhances the efficiency and effectiveness of processes of urban development. A pilot of the Urban Decision Room based on mathematical optimisation has been made for Schieoevers, an industrial area on the bank of the river Schie to the south of Delft. This pilot is based on a feasibility study for a new urban development in this area which has been carried out by a consultancy firm (Adecs BV) under commission from the municipality of Delft.

title	Mass-Customization in the Design of 4,000 Bus Stops
source	Computer Aided Architectural Design Futures 2011 [Proceedings of the 14th International Conference on Computer Aided Architectural Design Futures / ISBN 9782874561429] Liege (Belgium) 4-8 July 2011, pp. 265-278.
summary	In Hawaii, ‚"TheBus‚" has been a main transportation system since 1971. Considering the high cost of living in Hawaii and the absence of a rail system, the use of ‚"TheBus‚" has been an instrumental vein of the city life in Honolulu with rhythmical pauses at about 4,000 bus stops in Honolulu. However, existing undifferentiated bus stops are developed from a cost effective mass production system so that they have been problematic for satisfying specific needs from various site conditions. In this research, an integrated computational method of mass-customization for designing 4,000 bus stops is introduced. According to various site conditions, the design of each bus stop is customized. Unlike the mass‚Äêproduced bus stops commonly seen in cities today, the proposed computational method in this paper produces bus stop design outcomes that fit into the physical characteristics of the location in which they are installed. Mass-customization allows for the creation and production of unique or similar buildings and building components, differentiated through digitally‚Äêcontrolled variation (Kolarevic, 2003). The employment of a computational mass‚Äêcustomization in architectural design extends the boundary of design solutions to the satisfaction of multi-objective requirements and unlimited freedom to search alternative solutions (Duarte, 2001; Caldas, 2006). The computational method developed in this paper consists of 1) definition of a prototype, 2) parametric variation, 3) manual deformation, and 4) simulation based deformation. The definition of a prototype is the development of a basic design to be transformed for satisfying various conditions given from a site. In this paper, the bus stop prototype is developed from the analysis of more than 300 bus stops and the categorization of the existing bus stops according to their physical conditions, contextual conditions, climatic conditions, and existing amenities. Based upon the outcome of the analysis, the design variables of a bus stop prototype are defined. Those design variables then guide the basic physical parameters for changing the physical configuration of the prototype according to a given site. From this, many possible design outcomes are generated as instances for further developments. The process of manual deformation is where the designer employs its intuition to develop the selected parametric variation. The designer is compelled to think about the possible implication derived from formal variation. This optional process allows every design decision to have a creative solution from an individual designer with an incidental quality in aesthetics, but substantiated functional quality. Finally the deformation of the selection is guided and controlled by the influence of sun direction/ exposure to the selection. The simulation based deformation starts with the movement of the sun as the trigger for generating the variations of the bus stop prototype. The implementation of the computational method was made within the combination of MEL (Maya Enbedded Language), autodesk MAYA and Ecotect environment.

title	Developing a Virtual Test-Bed to Design Human-Centered Ubiquitous Space
source	Van Leeuwen, J.P. and H.J.P. Timmermans (eds.) 2006, Progress in Design & Decision Support Systems in Architecture and Urban Planning, Eindhoven: Eindhoven University of Technology, ISBN-10: 90-386-1756-9, ISBN-13: 978-90-386-1756-5, p. 359-369
summary	Future space is currently getting a great deal of attention to apply ubiquitous computing technology. To design these spaces, the need to make a physical test-bed, a real building model, is essential for human-centered design. However building a physical test-bed generally is economically expensive and even if the test-bed could be settled, it must be carefully designed before it is built. In this paper, we suggest a virtual smart test-bed, called 'V-PlaceLab'. This system allows not only to research a human behavior with the aid of computer simulation on a virtual environment, but also to design a human-centered ubiquitous space mentioned above.

title	Crowd Modeling and Simulation - The role of multi-agent simulation in design support systems
source	Van Leeuwen, J.P. and H.J.P. Timmermans (eds.) 2006, Innovations in Design & Decision Support Systems in Architecture and Urban Planning, Dordrecht: Springer, ISBN-10: 1-4020-5059-3, ISBN-13: 978-1-4020-5059-6, p. 105-120
summary	The paper presents a Multi Agent Systems (MAS) approach to crowd modelling, based on the Situated Cellular Agents (SCA) model. This is a special class of Multilayered Multi Agent Situated System (MMASS), a model providing an explicit representation of the environment which has a relevant role in supplying agents a context allowing them to act and interact (among themselves and with the environment). The paper will briefly introduce the model and a methodology for the analysis of a crowd scenario and the design of SCA based crowd simulations. The adoption of this kind of system allows evaluating an architectural design with reference to the behaviour of pedestrian that will act in it, given a behavioural specification for these entities. The system is also able to produce a realistic visualization of the simulation, in order to facilitate the communication with involved actors (e.g. in case of participatory decisions).

summary	This paper presents a novel approach for the automatic creation of vegetation scenarios in real or virtual 3D cities in order to simplify the complex design process and time consuming modeling tasks in urban landscape planning. We introduce shape grammars as a practical tool for the rule-based generation of urban open spaces. The automatically generated designs can be used for pre-visualization, master planning, guided design variation and digital content creation in general (e.g. for the entertainment industry). In a first step, we extend the CGA shape grammar by Müller et al. (2006) with urban planning operations. In a second step, we employ the possibilities of shape grammars to encode design patterns (Alexander et al., 1977). Therefore, we propose several examples of design patterns allowing for an intuitive high-level placement of objects common in urban open spaces (e.g. plants). Furthermore, arbitrary interactions between distinct instances of the vegetation and the urban environment can be encoded. With the resulting system, the designer can efficiently vegetate landscape and city parks, alleys, gardens, patios and even single buildings by applying the corresponding shape grammar rules. Our results demonstrate the procedural design process on two practical example scenarios, each one covering a different scale and different contexts of planning. The first example illustrates a derivation of the Garden of Versailles and the second example describes the usage of high-level rule sets to generate a suburbia model.

title	FabPOD: An Open Design-to-Fabrication System

summary	Digital workflows from the design to the production of buildings have received significant recent attention in architectural research. The need for both integrated systems for design collaboration (Boeykens and Neuckermans, 2006) and clear and flexible communication flows for non-standard fabrication outcomes have been identified as fundamental (Scheurer, 2010). This paper reports on the development of a digital “design system” for the design and prototyping of an acoustic enclosure for meetings in a large open work environment, theFabPod. The aim was to keep this system open for temporal flexibility in as many aspects of the finalisation of the design as possible. The system provides novel examples of both integrated collaboration and clear communication flow. (1) Acoustics is included as a design driver in early stages through the connection of digital simulation tools with design models. (2) Bi-directional information flows and clear modularisation of workflow underpins the system from design through to fabrication and assembly of the enclosure. Following the completion and evaluation of the FabPod prototype, the openness of the system will be tested through its application in subsequent design and prototyping iterations. Design development will respond to performance testing through user engagement methods and acoustic measurement.

summary	This research carried out an experiment to verify the usefulness of a WebGIS-based system that we have been developing (A support system for community-based disaster mitigation planning integrated with a fire spread simulation model using CA) BEFORE, DURING and AFTER Workshops. Based on the data collected from the experiment, the usefulness and advantages of the system were verified from various angles. As a result, it was found that even though there are still some issues to be solved, the system is useful and effective as a support tool and also in enhancing awareness before and after Workshops.
