title	Building Thailand's tallest Ganesh: CAD/CAM integration in conventional metal fabrication
source	Proceedings of the 17th International Conference on Computer Aided Architectural Design Research in Asia / Chennai 25-28 April 2012, pp. 337–346
doi	https://doi.org/10.52842/conf.caadria.2012.337
summary	Ganesh (Ganesa or Ganesha) is a Hindi god well known for his distinguishable elephant head and widely revered as the god of success or remover of obstacles. Patrons in Thailand have worshipped Ganesh and respected him by means of erecting statues of Ganesh in various poses and sizes throughout the country. In late 2008, the people of Chacheongsao, a province located East of Bangkok, decided to create Thailand’s tallest standing Ganesh statue made with bronze reaching heights up to 39 meters and situated on the Bangpakong river bank overseeing the city and its people. The author and design team was approached by representatives from Chacheongsao and commissioned to advise the process from conception to construction. The challenge started with seeking appropriate computer-aided design and manufacturing technologies and innovative processes to guide the design team throughout the production. The 0.60-meter bronze cast sculpture of the Ganesh was scanned using a 3D optical scanner to generate a solid model of the statue. A surface model was then extracted from the 3D model to firstly determine the most efficient structural support within the statue and secondly to generate surface strips for the foundry to create actual bronze casts. The construction of the project began early 2009 and the statue has since been erected from its base to currently its head. During construction, the author and design team has encountered several problems translating pixels to parts. Several errors have occurred during the mould and cast production process as well as construction errors on site causing mismatches of the structure and surface, misalignments, and protruding structural supports and joints. The lessons learned from this project is documented and analysed with hopes to create a more effective process for future projects with similar requirements.

title	Reflexão sobre seis residências emblemáticas a partir da tecnologia BIM e da fabricação digital [Reflection on emblematic residences from static / dynamic simulations and digital fabrication]
source	SiGraDi 2014 [Proceedings of the 18th Conference of the Iberoamerican Society of Digital Graphics - ISBN: 978-9974-99-655-7] Uruguay - Montevideo 12 - 14 November 2014, pp. 311-315
summary	The aim of this paper is to report the teaching experience held in 2012 at Unicamp between three disciplines of representation. Students analyzed emblematic residences from digital and physical models. Digital models were produced in Revit and its building components were diagrammed in AutoCad. After that, these elements were sent to laser cutter, and hand assembled. In 3DS Max, 3D model allowed simulations such as rendered images and animations. We report the contributions of these analog and digital artifacts in the design process. This article contributes to reflection and debate on the application of digital technologies in the analysis of iconic buildings of architecture.

title	Information System to Improve the Building Production Management Cooperative Work in Design and Architectural Production
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. 253-270
summary	Our work is to enable partners of a construction project (building owner, architect, engineer, etc.) to share all the technical data produced and manipulated during the building process, by setting up interfaces for an accessible information system via the internet. Our system would be able to deliver an answer to a user to a particular question asked. The system links databases and allows building partners to access and to manipulate specific information. This paper covers the information structure model based on building construction knowledge and the access to user-relevant information. First, the paper aims to establish the state of the art of the information systems available today in the building construction field. Second, we present the contribution of our research to the description of the building elements (foundations, ramps, stairs, etc.), where information is share by partners who are distant from one another and focused on fields of expertise that are distinct but concurrent. Our system links distributed databases and provides an updated building representation that is being enriched and refined all along the building life cycle. It consists of 3D representations of the building as well as data that are associated with each graphical entity (walls, slabs, beams, etc.).

title	In-Situ Robotic Construction: Extending the Digital Fabrication Chain in Architecture
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. 169-176
doi	https://doi.org/10.52842/conf.acadia.2012.169
summary	In this paper, viable applications of mobile robotic units on construction sites are explored. While expanding on potential objectives for in-situ fabrication in the construction sector, the intention is also to build upon innovative man-machine interaction paradigms to deal with the imprecision and tolerances often faced on construction sites. By combining the precision of the machine with the cognitive environmental human skills, a simple but effective mobile fabrication system is experimented for the building of algorithmically designed additive assemblies that would not be possible through conventional manual methods if the large amount of individual building blocks and the size of the structure to be built are taken into account. It is believed that this new approach to man-machine collaboration, aimed at a deeper integration of human ability with the strengths of digitally controlled machines, will result in advances in the construction sector, thus opening up new design and application fields for architects and planners.

title	Data sharing for sustainable assessments: Using functional databases for interoperating multiple building information structures
source	Proceedings of the 17th International Conference on Computer Aided Architectural Design Research in Asia / Chennai 25-28 April 2012, pp. 193–202
doi	https://doi.org/10.52842/conf.caadria.2012.193
summary	This paper presents the development and implementation of an automatic sustainable assessment prototype using functional databases. For the practical purpose, we use Leadership in Energy and Environmental Design (LEED) as the exemplar standard to demonstrate the integrative process from building information aggregation to final evaluation. We start with a Building Information model, and use Construction Operations Building Information Exchange (COBie) as a bridge to integrate LEED requirements. At present, the process of sustainable building assessment requires information exchange from various building professionals. However, there is no procedure to manage, or use, information pertaining to sustainability. In our research, we translate rules from LEED into computable formulas and develop a prototype application to produce templates for LEED submission.

title	Resilient Rules - Culture and Computation in Traditional 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. 211-221
summary	This study explores the influence of the socio-cultural rules, based upon Islamic jurisprudence (fiqh), on the complexity of the traditional built environment. This system of rules organized the societal activities, including decisions and activities related to design and construction in the Arab-Islamic city. Considering the city as a complex system, the study will try to show how this rules system made the Arab-Islamic city resilient and adaptive. Complex Adaptive Systems (CAS) are non-linear, self-organizing systems that have the ability to adapt to changing conditions through changing the rules that organize the random autonomous interactions between agents in the environment. This adaptation takes place through gradual gained experience that is reflected in the behavior of agents. This study attempts to interrelate different bodies of literature (Complexity/Chaos theory and built environment studies) in a single framework that aims to show that the socio-cultural rules system based on fiqh was a major factor in the resilience of the traditional built environment. These interrelations are illustrated using a graph called Computational Rules Graph (CRG). The CRG relates the traditional rules system to attributes of complex systems in a graph that can be modeled computationally. Traditional rules (codes of conduct) are proscriptive (non-deterministic), defining what is prohibited, thereby producing autonomous environments where agents had control over their immediate environment. In comparison, contemporary rules of the built environment (building codes) are prescriptive (deterministic), subscribing definite actions that need to take place by the stake-holder (agent) neglecting user needs and preferences. The application of these traditional rules system increased the agent’s autonomy and freedom of action. It also helped establish stronger social networks among agents, which resulted in a resilient environment.

title	Numerical Simulation of Effect of Urban Geometry Layouts on Wind and Natural Ventilation Under Mediterranean Climate
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. 195-202
summary	The use of the method "simulation" of the microclimate for an urban site presents much of interest; because this can serve as us observation and analysis of the consequences of various scenarios relating to the existence and the importance of the constituent elements in urban space. Wind in outdoor urban space is among the most difficult parameters to identify and control field given its instability. Currently, in the field of the ventilation, there are some outdoor spaces simulation tools, used to assess the flow of the wind at different spatial scales. The aim of this research is to demonstrate the effect of the urban geometry of the layout on the wind movement and the outdoor natural ventilation. However, this study investigated the effect on outdoor thermal comfort of a building layouts in a planned residential area situated in the city of Jijel humid Mediterranean region of Algeria. In order to improve outside comfort in this open space, a 3D numerical simulation tool ENVI-met 3.1 beta 4 was used to simulate the urban thermal climate taking into account various scenarios. Thus, simulation’s results are discussed in this paper

summary	This paper presents a general 3D shape grammar interpreter named GRAMATICA and illustrates its use for the implementation of several shape grammars, including the one used in the design module of a specifi c shape grammar for mass-customized housing, called DESIGNA. The underlying shape representation, generation and control are discussed. The resulting shape grammar interpreter tries to support designers’ ways of thinking and working by acting as a bridge between shape grammars, the formalism that captures a design process, and a CAD application, for post-processing the computed design. This bridge is implemented by Rosetta, which ensures portability among different CAD applications.

summary	This article aims to promote the discussion about how the adoption of Building Information Modeling systems in management processes and three-dimensional geometric modeling can interfere in the design process and construction of complex shapes in architecture. To that end, we assembled a theoretical-practical referential about the use of non-Euclidean forms in contemporary architecture and BIM tools, illustrated with iconic design processes developed by Frank Gehry and Zaha Hadid. Finally, there was the importance of BIM tools to a new understanding of architecture, by enabling the construction of complex shapes.

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	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.

title	Synchronous Horizons: Redefining Spatial Design in Landscape Architecture Through Ambient Data Collection and Volumetric Manipulation
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. 355-361
doi	https://doi.org/10.52842/conf.acadia.2012.355
summary	The premise of this paper addresses the limited shared vocabulary of landscape architecture and architectural design - evident in the application of terms such as ‘spatial design’ and ‘spatial planning’. In their current usage, such terms emphasize the visible, terrestrial, pedestrian perspective level, often to the absolute exclusion of a spatial, ie. volumetric, comprehension of the environment. This deficit is acutely evident in the education of Landscape Architecture and Architecture, and discussion of their shared ground. The dominant document to map such analysis and design is the plan, or 3d-dimensional representations of the same, restricted to an extrusion or height map. GIS techniques in spatial design tend to be weighted towards visual, surface based data (slope analysis, exposure, viewshed etc.). Our goal within this domain lies in transforming aspects of the intangible - the characteristics of open space itself - into a form that is legible, quantifiable, and malleable.

title	Cellular Robotic Architecture
source	International Journal of Architectural Computing vol. 10 - no. 3, 319-339
summary	An emerging need for interactive architecture is currently making buildings mutable, flexible in use, and adaptable to changes in climate by introducing robotic systems. However, the feasibility of the seamless integration of building construction details and kinetic robotics has become a critical issue for developing robotic architecture. The objective of this work is to develop a robotic architecture with an emphasis on the integration of cellular robotics with a distributed kinetic building surface. The kinetic building surface integrates an actuating system, a localization and remote control system, which become part of the kinetic building system. This paper presents a systematic framework by reviewing theories and related work of robotic architecture and automated control. An architectural design scheme is proposed to simulate a scenario of application in a physical space. The functionality of the electrical and control system and the integration of the effects of actual construction were examined by a prototype of a kinetic surface. Our prototype presents a feasible construction method, and a prominent energy-saving effect. The potential strength and restrictions of the cellular robotic approach to architectural applications are discussed. The applicability of the prototype system and issues about controlling the behavior of spatial robots are demonstrated in this paper.

The design was developed by Le Corbusier and his studio for the International Expo held in Brussels in 1958, for the Philips fi rm, and it was destroyed some months later, after the event. The research investigated the complex geometry of the structure in order to understand the strict relation between the physical perception of the space and the electronic aspects of them, using advanced technology, but, above all, if it is true that the best way to understand the physicality of a destroyed architecture could be a virtual visit using electronic devices and digital procedures.

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	Point Cloud Segmentation for Building Reuse - Construction of digital twins in early phase building reuse projects
source	Dokonal, W, Hirschberg, U and Wurzer, G (eds.), Digital Design Reconsidered - Proceedings of the 41st Conference on Education and Research in Computer Aided Architectural Design in Europe (eCAADe 2023) - Volume 2, Graz, 20-22 September 2023, pp. 327–336
doi	https://doi.org/10.52842/conf.ecaade.2023.2.327
summary	Point cloud processing has come a long way in the past years. Advances in computer vision (CV) and machine learning (ML) have enabled its automated recognition and processing. However, few of those developments have made it through to the Architecture, Engineering and Construction (AEC) industry. Here, optimizing those workflows can reduce time spent on early-phase projects, which otherwise could be spent on developing innovative design solutions. Simplifying the processing of building point cloud scans makes it more accessible and therefore, usable for design, planning and decision-making. Furthermore, automated processing can also ensure that point clouds are processed consistently and accurately, reducing the potential for human error. This work is part of a larger effort to optimize early-phase design processes to promote the reuse of vacant buildings. It focuses on technical solutions to automate the reconstruction of point clouds into a digital twin as a simplified solid 3D element model. In this paper, various ML approaches, among others KPConv Thomas et al. (2019), ShapeConv Cao et al. (2021) and Mask-RCNN He et al. (2017), are compared in their ability to apply semantic as well as instance segmentation to point clouds. Further it relies on the S3DIS Armeni et al. (2017), NYU v2 Silberman et al. (2012) and Matterport Ramakrishnan et al. (2021) data sets for training. Here, the authors aim to establish a workflow that reduces the effort for users to process their point clouds and obtain object-based models. The findings of this research show that although pure point cloud-based ML models enable a greater degree of flexibility, they incur a high computational cost. We found, that using RGB-D images for classifications and segmentation simplifies the complexity of the ML model but leads to additional requirements for the data set. These can be mitigated in the initial process of capturing the building or by extracting the depth data from the point cloud.

summary	The use of digital design and fabrication technologies in architecture has followed a paradigm shift, which has seen the topology, form and structure of architecture pushed to incorporate areas such as climate, construction, acoustic etc. While these digital technologies are intended to enhance the processes and performance, a discussion of aesthetics has been ignored. Surmising that the use of digital technology enhances the performability and effi ciency aspects of architecture as well as the aesthetics, this research questions what the new relationships and arrangements for structure and ornament are. What are the challenges when structure uses a process-based logic and is sensitive to materiality whereas the aesthetics has a representation-based logic and is not sensitive to materiality? The authors of this paper contribute to this debate by using the notion of tectonic as a platform for gaining and creating knowledge about this issue and examining the issues through the design and prototyping of a Multi-functional Pavilion.
