summary	Industrial robots for architectural fabrication have not yet been directly linked to the design process, as current research focuses mostly on the automated generation of robot control data for mass customization. In this paper, we will discuss the use of a real-time programming environment for robot simulation/control and introduce a virtual robot, that allows architects to digitally prototype fabrication processes. While such a real-time approach is also suitable for mass customization, the main advantage is that this interaction with the virtual-robot can be used to intuitively solve complex fabrication problems.

summary	This paper is part of an ongoing research that analyzes the housing projects of the Dutch office MVRDV through their theoretical research and design processes. The text focuses on the use of parametric software according to two key aspects that qualify their production: research and conceptual creative potential. Since the late 1990s, the architects are positioning their practice under a strategy that combines collection, processing and interpretation of large amounts of data, what means the conversion of statistical information into concrete and inventive form. With this demand the office developed parametric software as Regionmaker, the case study presented here.

summary	It is an immutable truth that architecture ultimately exists for humans. Similarly, it is a well-known fact that countless architectural concepts derived and evolved to restrain development, to control building projects and to consider environment are eventually for the benefit of humans. Architecture today, however, is in the hands of a few renowned architects even though it is supposed to refl ect human beings and times and to work for everyone. Is it too much to say that everyone should have a say in the space used by many? In that respect, we have devised DADL System. Anyone, Anytime, Anywhere. The system is an architectural game that stimulates human instincts, has online communities and is easily accessible by Anyone Anytime and Anywhere (3A Rules). DADL System aims to gather users’ ideas and develop architecture, which is essentially enabled by the ‘Advise’ feature. Advise is designed to lead users to think about architecture voluntarily and to guide them to express their ideas. The structure and contents of Advises are very important factors in DADL System. Also, it is divided into two domains, i.e. Web and Mobile, where data exchange is enabled via cloud computing, establishing a base in compliance with the ‘3A’ Rules. The DADL System supports the architecture of everyone without relying on opinions of a few, so as to open the infi nitive potential for communication between architecture and humans, which today’s architecture should advocate.

summary	This research presents a solution for evaluation of kinetic façades system performance via experiences and lessons learnt from experiments. We bridge between architects and engineers to address limitations associated with incorporating performance criteria in the design of kinetic façades by integrating different simulation tools. The experiments focus on optimization of the daylight performance through the design and motion of kinetic façades using various integrated software. The research is developed using real time data feedback processed through various digital tools from three domains: (1) Architectural design, (2) day-lighting performance and (3) parametric design computation. From the evaluations, the paper demonstrates the analysis of kinetic motion for daylight optimization at the early design stage and suggests possible configurations for daylight performance.

title	A Crowdsourcing Urban Simulation Platform on Smartphone Technology: Strategies for Urban Data Visualization and Transportation Mode Detection

summary	We propose a crowdsourcing simulation environment that brings human intention into the urban simulator. Our fundamental goal is to simulate urban sustainability by employing direct human interaction. In this paper we present a prototype mobile phone application that implements a novel transportation mode detection algorithm. The mobile phone application runs in the background and continuously collects data from the built-in acceleration and network location sensors. The collected data is analyzed by the transportation mode detection algorithm and automatically partitioned into activity segments. A key observation of our work is that walking activity can be robustly detected in the data stream and acts as a separator for partitioning the data stream into other activity segments. Each vehicle activity segment is then sub-classifi ed according to the type of used vehicle. Our approach yields high accuracy despite the low sampling interval and not requiring GPS data that bring minimized device power consumption. Ultimately, the collected information can be translated into real-time urban behavior and will indicate sustainability, both on the personal and the city level.

summary	For most architects, it is not easy to transform their freeform designs into buildable constructions without precise knowledge on a specifi c material and its construction process.A workfl ow is introduced in this paperand it could be adopted by architects concerning the works of predicting the tiling results in the earliest design stage.The workfl ow involves pre-processing which could help architects design rational surfaces, thus saving a lot of work in the paneling process later on. The physically based modeling engine will simulate the constraints of a pre-selected material and therefore ensures a feasible result. The post-process involves visual feedback of the result as well as data formatting which help to establish a seamless connection between construction processes.

title	Making use of Point Cloud for Generating Subtractive Solar Envelopes

summary	As a contextual and passive design strategy, solar envelopes play a great role in determining building mass based on desirable sun access during the predefined period. With the rapid evolution of digital tools, the design method of solar envelopes varies in different computational platforms. However, current approaches still lack in covering the detailed complex geometry and relevant information of the surrounding context. This, consequently, affects missing information during contextual analysis and simulation of solar envelopes. This study proposes a subtractive method of solar envelopes by considering the geometrical attribute contained in the point cloud of TLS (terrestrial laser scanner) dataset. Integration of point cloud into the workflow of solar envelopes not only increases the robustness of final geometry of existing solar envelopes but also enhances awareness of architects during contextual analysis due to consideration of surface properties of the existing environment.

title	A Web-Based Virtual Reality Model for Preliminary Estimates of Hi-Rise Building Projects
source	Timmermans, Harry (Ed.), Sixth Design and Decision Support Systems in Architecture and Urban Planning - Part one: Architecture Proceedings Avegoor, the Netherlands), 2002
summary	Cost estimating of a construction project at its early stage is considered to be very important task since it will be used as a base to commit or otherwise not to commit funds to that project. Preparation of a reliableand realistic preliminary estimate to aid the decision makers to commit funds for a specific project is a complicated assignment. Traditional methods and operations produced unsatisfactory aid due to lack ofaccuracy especially in the pre-design stage of a project. This participates in the increase of percentage of bankruptcy in the construction industry, which has dramatically climbed up and ranked as 15 percent of thewhole bankruptcies claimed in Canada (Statistic Canada 1998). This paper presents a methodology for developing and a Web-based model to automate preliminary cost estimates for hi-rise buildings. This is achieved by integrating a database with design drawings in a Virtual Reality (VR) environment. The model will automatically generate preliminary estimates after modifying a 3D CAD drawing. It provides the user the option to visualize and simulate the drawing and its cost data through VR environment. Having done that, it will allow owners, architects and cost engineers to view a constructed building project, change its geometric objects and shapes, and accordingly generate a new conceptual cost estimate.

title	The Architecture of ScarCity Game - The craft and the digital as an alternative design process
source	Sousa, JP, Xavier, JP and Castro Henriques, G (eds.), Architecture in the Age of the 4th Industrial Revolution - Proceedings of the 37th eCAADe and 23rd SIGraDi Conference - Volume 3, University of Porto, Porto, Portugal, 11-13 September 2019, pp. 45-52
doi	https://doi.org/10.52842/conf.ecaade.2019.3.045
summary	The Architecture of ScarCity Game is a board game used as a pedagogical tool that challenges architecture students by involving them in a series of experimental design sessions to understand the design process of scarcity and the actual relation between the craft and the digital. This means "pragmatic delivery processes and material constraints, where the exchange between the artisan of handmade, representing local skills and technology of the digitally conceived is explored" (Huang 2013). The game focuses on understanding the different variables of the crafted design process of traditional communities under conditions of scarcity (Michel and Bevan 1992). This requires first analyzing the spatial environmental model of interaction, available human and natural resources, and the dynamic relationship of these variables in a digital era. In the first stage (Pre-Agency), the game set the concept of the craft by limiting students design exploration from a minimum possible perspective developing locally available resources and techniques. The key elements of the design process of traditional knowledge communities have to be identified (Preez 1984). In other words, this stage is driven by limited resources + chance + contingency. In the second stage (Post-Agency) students taking the architects´ role within this communities, have to speculate and explore the interface between the craft (local knowledge and low technological tools), and the digital represented by computation data, new technologies available and construction. This means the introduction of strategy + opportunity + chance as part of the design process. In this sense, the game has a life beyond its mechanics. This other life challenges the participants to exploit the possibilities of breaking the actual boundaries of design. The result is a tool to challenge conventional methods of teaching and leaning controlling a prescribed design process. It confronts the rules that professionals in this field take for granted. The game simulates a 'fake' reality by exploring in different ways with surveyed information. As a result, participants do not have anything 'real' to lose. Instead, they have all the freedom to innovate and be creative.

doi	https://doi.org/10.52842/conf.ecaade.2019.3.305
summary	In this research, we attempt to develop a tool which integrates certain common geographic information from OpenStreetMap and OpenTopography into Grasshopper. We name it as OSMKIT temporarily. Besides, in order to make the integration in the design process easier, this tool includes the bilateral conversion function of coordinate in Rhinoceros 3D and the coordinate of the World Geodetic System. These characteristics bring about several possibilities for further usage. This paper contains explanations of functions and examples. For instance, it can be employed for data visualization on a map when these data contain coordinate information. Additionally, since this tool is simple and intuitive to convert points into GPS coordinates, it can make users plan drone for photogrammetry and deal with other related tasks on the rhinoceros 3D interface, helping them to gain most current urban models. Moreover, architects or designers can be not only users but also contributors for open source map system such as OpenStreetMap; the process of sharing the mode which user measure is demonstrated in this paper. To sum up, this coordinate system based tool is designed to be multifunctional and suitable for interdisciplinary usages in grasshopper.

source	Timmermans, Harry (Ed.), Sixth Design and Decision Support Systems in Architecture and Urban Planning - Part one: Architecture Proceedings Avegoor, the Netherlands), 2002
summary	The European project DIAL-Europe started in April 2000 and intends to enhance and to enlarge the capabilities of the LesoDIAL software. The aim of this “Swiss” tool was to give architects relevant information regarding the use of daylight, at the very first stage of the design process. DIAL-Europe focuses on European standards and climatic data. Further, a Heating & Cooling evaluation module and an Artificial Lighting module will be added. The objective of the Heating & Cooling module is to indicate the implications of the user’s design on heating and cooling energy and on thermal comfort.The objective of Artificial Lighting module is to develop a tool that will give an estimation of illuminance values on the work plane and provide guidance on qualitative aspects and visual comfort as well as on switching control and integration with daylight based on generic light sources and luminaires. Furthermore, the scope of the examples of simulated rooms will be increased in order to allow the user to compare their design with more similar cases. This paper will present the state of achievement and give an overview of the first version of the DIAL-Europe software, which will beavailable at the beginning of 2002.

title	A Research on Housing in Ankara-Turkey
source	Timmermans, Harry (Ed.), Fourth Design and Decision Support Systems in Architecture and Urban Planning Maastricht, the Netherlands), ISBN 90-6814-081-7, July 26-29, 1998
summary	The subject of this research contains an opinionnaire study and its results obtained from 30 houses in Ankara-TURKEY in which the people have middle and upper middle income so as to identify their favourites and criticsm about housing, regarding to their both houses and environment as well as tomake the definition of ideal houses and environment. Totally 30 subjects of which 21 are female and 9 are male which represent middle and upper middle incomed people. The average age of the subjects whose age range vary between 21 and 70 is 41. In the study, firstly, the opinionnaire questions were prepared and the housing in which the middle and upper middle incomed people live were determined as socio-economic level to be examined. Next permission and time reservation were requested fromthe owner's of housing to implement the study. During the times which have been determined by the subjects, the following procedure has been followed reading of the opinionnaire forms by myself and recording of responses of the subjects exactly, drawing of reliefs and plans of house, taking pictures of outer views and surroundings of housings. Tendencies of users' against various conditions have been transformed into numerical values from 1 to 7 in a scale with 7 column. In the light of above information; Considering the country conditions it was observed that these housing were excessivelylarge and were built for ostentation purposes, not for functional purposes. Usefulness, that is to say, design of house is in the bottom of the criteria list and it is not an important factor to choose the house, form another part of interesting findings of this study. Another significant result has been observed due to users desire about their house. Although the rising of design which was in 6th rank among the reasons to prefer a house was not an effective criteria on users' attitudes merely to have ahouse, this criteria was the 1st rank (87 %) among reasons due to the advantages that were provided for the users with respected to design and functionality as a result of meticulous studies of architects.Users' criticisms on their vicinity have shown variations according to their sexes.As a result of this research that were initiated to define the ideal house and environment concepts; interesting and detailed data about users' tendencies in the scope of both house and settling are available in "Findings" part of this study. Rising of desing criteria which was the 6 th rank amongcriteria's to choose a house, to 1st rank has brought the following conclusion: since the users are not able to act consciously due to the consideration of the properly owing action much more important,the main duty here is performed by the planner. Hence, starting from the assumption that users living in housings are extremely sensitive to their houses and especially environments, provision of public participation via this kind of opinionnaire studies while creating new environments, may contribute to create such environments in which people can live.

summary	The paper discusses the design and testing of sustainable recycled materials for large scale 3D printed construction in a marine context. This research is part of a 3-phase project involving a multidisciplinary team of designers, architects, material specialists and marine ecologists. The Bio Shelters Project uses an innovative approach to designing and fabricating marine bio-shelters that ecologically enhance seawalls, by promoting native biodiversity and providing seawater filtration, carbon sequestration and fisheries productivity. The design of the 3D print structure is a data-driven approach that incorporates ecological data to optimise the form for growth and survivorship of marine species under the environmental conditions of the installation site as well as being an integral part of the design project and the site.

title	Thermal Simulation In Residential Building Within Computer Aided Architectural Design: Integrated model
source	Digitizing Architecture: Formalization and Content [4th International Conference Proceedings of the Arab Society for Computer Aided Architectural Design (ASCAAD 2009) / ISBN 978-99901-06-77-0], Manama (Kingdom of Bahrain), 11-12 May 2009, pp. 235-243
summary	Nowadays, the architectural profession is seeking a better energy saving in the design of buildings. The fear of energy shortage in the very near future, together with the rapid rise in energy prices, put pressure on researchers on this field to develop buildings with more efficient heating systems and energy systems. This work is concerned mainly with the development of a software program analyzing comfort in buildings integrated in CAD architectural systems. The problem of presenting the computer with information concerning the building itself has been overcome through integration of thermal analysis with the building capabilities of CAD system. Mainly, such experience concerns the rules for calculating heat loss and heat gain of buildings in Algeria, The program has been developed in order to demonstrate the importance of the innovation of the computer aided-architectural-design field (CAAD) in the technology of buildings such as the three dimensional modeling offering environmental thermal analysis. CAAD is an integrated architectural design system which can be used to carry out many tasks such as working drawings, perspectives and thermal studies, etc., all from the same data. Results are obtained in tabular form or in graphical output on the visual display. The principle of this program is that all input data should be readily available to the designer at the early stages of the design before the user starts to run the integrated model. Particular attention is given to the analysis of thermal aspects including solar radiation gains. Average monthly energy requirement predictions have been estimated depending on the building design aspect. So, this integrated model (CAAD and simulation comfort) is supposed to help architects to decide on the best options for improving the design of buildings. Some of these options may be included at the early design stages analysis. Indications may also be given on how to improve the design. The model stored on CAAD system provides a valuable data base for all sort analytical programs to be integrated into the system. The amount of time and expertise required to use complex analytical methods in architectural practice can be successfully overcome by integration with CAAD system.

title	A decision-making process for choice of a flexible internal partition option in multi-unit housing using decision theory techniques
source	Timmermans, Harry (Ed.), Design and Decision Support Systems in Architecture (Proceedings of a conference held in Mierlo, the Netherlands in July 1992), ISBN 0-7923-2444-7
summary	Recent demographic changes have increased the heterogeneity of user groups in the North American housing market. Smaller households (e.g. elderly, single parent) have non-traditional spatial requirements that cannot be accommodated within the conventional house layout. This has created renewed interest in Demountable/Flexible internal partition systems. However, the process by which designers decide which project or user groups are most suited for the use of these systems is quite often complex, non-linear, uncertain and dynamic, since the decisions involve natural processes and human values that are apparently random. The anonymity of users when mass housing projects are conceptualized, and the uncertainty as to the alternative to be selected by the user, given his/her constantly changing needs, are some contributing factors to this effect. Decision Theory techniques, not commonly used by architects, can facilitate the decision-making process through a systematic evaluation of alternatives by means of quantitative methods in order to reduce uncertainty in probabilistic events or in cases when data is insufficient. The author used Decision Theory in the selection of flexible partition systems. The study involved a multi-unit, privately initiated housing project in Montreal, Canada, where real site conditions and costs were used. In this paper, the author outlines the fundamentals of Decision Theory and demonstrates the use of Expected Monetary Value and Weighted Objective Analysis methods and their outcomes in the design of a Montreal housing project. The study showed that Decision Theory can be used as an effective tool in housing design once the designer knows how to collect basic data.

summary	The understanding of space relies on motion, as we experience space by crossing it in time, space’s fourth dimension. However, architects lack the necessary tools to incorporate people's motion into their design of space. As a consequence, architects fail to connect space with the motion of the people that inhabit their buildings, creating disorienting environments. Further, what if augmentation technology changes how we inhabit space and the static built environment does not fit people anymore? This paper explores the problem of developing a model from people's motion, to inform and augment the architecture design process in the early stages. As an outcome, I have designed a model based on data from human-space interaction obtained through field work. First, relevant behavior was identified and recorded. Second, a metric was extracted from the data and composed by speed, the 4th D dimension as time, and gestures. Third, the original behavior was rebuilt, producing a set of rules. The rules were combined to form the model of human-space interaction. This generalizable model provides a novel approach to designing space based on data from people. Moreover, this paper presents a means of incorporating inhabitants' behavior into digital design. Finally, the model contributes to the advancement of people's motion research for general applications, such as in transport engineering, robotics, and cognitive sciences.

title	A strategy for complex-curved building design:Design structure with Bi-lateral contouring as integrally connected ribs

summary	Shapes in designs created by architects such as Gehry Partners (Shelden, 2002), Foster and Partners, and Kohn Peterson and Fox rely on computational processes for rationalizing complex geometry for building construction. Rationalization is the reduction of a complete geometric shape into discrete components. Unfortunately, for many architects the rationalization is limited reducing solid models to surfaces or data on spread sheets for contractors to follow. Rationalized models produced by the firms listed above do not offer strategies for construction or digital fabrication. For the physical production of CAD description an alternative to the rationalized description is needed. This paper examines the coupling of digital rationalization and digital fabrication with physical mockups (Rich, 1989). Our aim is to explore complex relationships found in early and mid stage design phases when digital fabrication is used to produce design outcomes. Results of our investigation will aid architects and engineers in addressing the complications found in the translation of design models embedded with precision to constructible geometries. We present an algorithmically based approach to design rationalization that supports physical production as well as surface production of desktop models. Our approach is an alternative to conventional rapid prototyping that builds objects by assembly of laterally sliced contours from a solid model. We explored an improved product description for rapid manufacture as bilateral contouring for structure and panelling for strength (Kolarevic, 2003). Infrastructure typically found within aerospace, automotive, and shipbuilding industries, bilateral contouring is an organized matrix of horizontal and vertical interlocking ribs evenly distributed along a surface. These structures are monocoque and semi-monocoque assemblies composed of structural ribs and skinning attached by rivets and adhesives. Alternative, bi-lateral contouring discussed is an interlocking matrix of plywood strips having integral joinery for assembly. Unlike traditional methods of building representations through malleable materials for creating tangible objects (Friedman, 2002), this approach constructs with the implication for building life-size solutions. Three algorithms are presented as examples of rationalized design production with physical results. The first algorithm [Figure 1] deconstructs an initial 2D curved form into ribbed slices to be assembled through integral connections constructed as part of the rib solution. The second algorithm [Figure 2] deconstructs curved forms of greater complexity. The algorithm walks along the surface extracting surface information along horizontal and vertical axes saving surface information resulting in a ribbed structure of slight double curvature. The final algorithm [Figure 3] is expressed as plug-in software for Rhino that deconstructs a design to components for assembly as rib structures. The plug-in also translates geometries to a flatten position for 2D fabrication. The software demonstrates the full scope of the research exploration. Studies published by Dodgson argued that innovation technology (IvT) (Dodgson, Gann, Salter, 2004) helped in solving projects like the Guggenheim in Bilbao, the leaning Tower of Pisa in Italy, and the Millennium Bridge in London. Similarly, the method discussed in this paper will aid in solving physical production problems with complex building forms. References Bentley, P.J. (Ed.). Evolutionary Design by Computers.

summary	This paper illustrates the synergy of non-manifold topology (NMT) and a branch of artificial intelligence and machine learning (ML) called reinforcement learning (RL) in the context of evaluating fire egress in the early design stages. One of the important tasks in building design is to provide a reliable system for the evacuation of the users in emergency situations. Therefore, one of the motivations of this research is to provide a framework for architects and engineers to better design buildings at the conceptual design stage, regarding the necessary provisions in emergency situations. This paper presents two experiments using different state models within a simplified game-like environment for fire egress with each experiment investigating using one vs. three fire exits. The experiments provide a proof-of-concept of the effectiveness of integrating RL, graphs, and non-manifold topology within a visual data flow programming environment. The results indicate that artificial intelligence, machine learning, and RL show promise in simulating dynamic situations as in fire evacuations without the need for advanced and time-consuming simulations.

summary	Today, architectural models are an important tool for illustrating drawn-on plans or computer-generated virtual models and making them understandable. In addition to the conventional methods for the manufacturing of physical models, a wide range of processes for Direct Digital Manufacturing (DDM) has spread rapidly in recent years. In order to facilitate the application of these new methods for architects, this contribution examines which technical and economic results are possible using 3D printed architectural models. Within a case study, it will be shown on the basis of a multi-storey detached house, which kind of data preparation is necessary. The DDM of architectural models will be demonstrated using two widespread techniques and the resulting costs will be compared.
