summary This paper presents a currently on-going research trajectory, investigating integrated design and build work-fl ows using generative design strategies and custom built fabrication devices. The aim of the research, which is being developed through a series of experiments and workshops, is to explore scenarios in which these work-flows can produce emergent architectural structures which are highly adapted towards the intended performance within their specifi c context and site. The research has produced a number of installations and prototypical structures which test the practical and theoretical dimensions of the methodology explored. This paper will introduce intriguing new scenarios in which the architects’ role is focused on an indirect, advanced level of control of the process of design, allowing for a more open-ended method of negotiation between structure, users and environment.

title Point Cloud Segmentation for Building Reuse - Construction of digital twins in early phase building reuse projects

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.

title Behavioural Prototypes In Spatial Design Computation
source In Petruschat and Adenauer (eds), Neue Formen des Prototypings in Gestaltungsprozessen, Form+Zweck, Berlin, 2012
summary Architects by profession, Christian Derix and Asmund Gamlesæter are interested in expanding the capabilities of digital technology to inform, support and enrich the design process in architecture and spatial planning. The computational prototypes they develop range from form studies to visualization of complex processes in spatial planning such as movement behaviors of people in a city. They work analytically as well as generatively and the approach is deeply affected by the understanding that computing systems should not define solutions but offer creative freedom and create a symbiosis between the designer and the algorithmic intelligence. They are rather designed to help the designer view the design problem and consequences of decisions from different perspectives. Encouraging the designer to play through different narratives. They are rather tools for thinking through multiple solutions and allow the designer to play with the possibilities. The generation of the final design is inspired and validated by the tools but remains in the hands of the designer.

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.

summary This paper chronicles an intensive student workshop on sensponsive architecture, from the educators’ point of view, underlying the pedagogical notes on this new design approach that employs digital design tools and electronic assemblies to creatively experiment with human-computer interaction. The workshop presented the theoretical, computational and fabricating frameworks for a human-centered approach to spaces with sensponsive partitions that respond timely with sense, displaying an adaptive behavior through time. The workshop theme was further specialized to direct the design outcome toward sensponsive environments for children that can help them perceive, experience and develop a meaningful understanding of the world around them through play.

title Designing CAAD for Creativity
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. 7-9
summary Can we design CAAD to enhance creativity? CAAD is often considered a tool that assists architects in design by managing documentation and facilitating visualization. While there has been anecdotal concern that CAAD inhibits creativity, there is empirical evidence that CAAD can enhance creativity. The challenge is to develop principles for designing CAAD for creativity based on theoretical and empirical research on recognizing and enhancing individual and distributed creative cognition. This presentation describes three concepts that can lead to principles for designing CAAD to enhance human creativity: recognition, perception, and diversity. // 1. Recognition: A framework for recognizing and evaluating creative design, shown in Figure 1, is developed based on research in psychology and design science that includes novelty, value, and surprise. This framework provides a basis for comparing and evaluating the impact of CAAD on creativity. 2. Perception: Perception affects cognition and therefore interaction design is a critical component of designing CAAD for creativity. The results of an empirical study, shown in Figure 2, using a protocol analysis find that changing perception to include tangible user interfaces has a positive effect on creative cognition. These results lead to design principles for increasing perceptual modalities in future CAAD systems. 3. Diversity: A theoretical framework for social and collective intelligence in design show how an increase in cognitive diversity leads to an increase in innovation. Using this framework we can develop design processes that combine the benefits of individual, team, and crowdsourced design ideas, as shown in Figure 3.

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 Architecture today has come to its most complex form. There are lots of criteria such as fi re safety, structure, sustainability etc… which must be controlled by the designers. To improve the performance and accessibility of buildings, governing bodies publish different codes for each of the different criteria. Buildings must comply with these codes to get a permit for construction. The checking of the buildings according the codes is done manually by code offi cials. This process is time consuming, high in cost and prone to errors. To remedy this problem by using the tools like BIM and AI, systems that can automatically check the code compliance of projects are being developed. In this paper we provide an overview of the structures and capabilities of these systems and present the automated code compliance checking system that we develop for checking building models against some parts of the Turkish Fire Codes.

Computer models and physical prototypes were produced in order to develop construction details and preview results. We compared this exercise with the method used to design Aviva Stadium in Dublin. It was possible to conclude that the use of a generative method along with automated procedures did not restrict creativity, allowing the quick exploration of multiple design alternatives.

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.

Automated procedures were used in the process: a script that generated sets of random points and a plug in that automatically generated polygons based on these points. Computer models, scale models and full scale prototypes were produced in order to develop construction details and preview results. It was possible to conclude that the use of a generative method along with automated procedures is far from restricting creativity, allowing the quick exploration of multiple design alternatives.

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.

Drawing on constructivist theories of learning / teaching aimed to observe the potential of this tool to effectively approach to such concepts. A systematic held in the form of concept maps, is constituted as a learning object for the subject in question.

summary In this paper we present an environment for conceptual design which mimicsthe interaction of designers with physical mockups. We present novel three dimensional on-and-above-the-surface interactive techniques which combine asymmetric bimanual operations with multi-touch direct manipulation on a fl at surface and depth cameras. These take advantage of a continuous interaction space to create and edit 3D models in a stereoscopic environment. To allow modeling architectural shapes directly, we combine hand and finger tracking in the space above the table with multi-touch on its surface without the need to change modes. This provides an alternative design environment where users can seamlessly switch between interacting on the surface or in the space above it depending on the task, which makes it easier to model complex shapes using simple operations.

summary The paper presents a series of design build studio that investigate the role of waste as building material. The series develops proposals for constructions that use CAAD and CAM tools in combination with traditional fabrication tools to design and build an installation out of waste materials. The fi rst construction uses waste to create two installations that questions human consumption, The second project is a future project, that intends the use of waste as an actual building material. Recycling is in the process of becoming an integral part of sustainable architecture. However, there are very few digital design projects that use re-used or recycled materials in combination with their architectural and aesthetic qualities and potentials. The potential of such an investigation is explored within these design build studios. What is junk? What is a building material? What are the aesthetics of junk?

title Zero-Waste, Flat-Packed, Tri-Chord Truss: Continued Investigations of Structural Expression in Parametric Design"
doi https://doi.org/10.52842/conf.acadia.2012.199
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. 199-208
summary The direct and rapid connections between scripting, modeling and prototyping allow for investigations of computation in fabrication. The manipulation of planar materials with two-dimensional CNC cuts can easily create complex and varied forms, volumes, and surfaces. However, the bulk of research on folding using CNC fabrication tools is focused upon surfaces, self-supporting walls and shell structures, which do not integrate well into more conventional building construction models. This paper attempts to explain the potential for using folding methodologies to develop structural members through a design-build process. Conventional building practice consists of the assembly of off-the-shelf parts. Many times, the plinth, skeleton, and skin are independently designed and fabricated, integrating multiple industries. Using this method of construction as an operative status quo, this investigation focused on a single structural component: the truss. Using folding methodologies and sheet steel to create a truss, this design investigation employed a recyclable and prolific building material to redefine the fabrication of a conventional structural member. The potential for using digital design and two-dimensional CNC fabrication tools in the design of a foldable truss from sheet steel is viable in the creation of a flat-packed, minimal waste structural member that can adapt to a variety of aesthetic and structural conditions. Applying new methods to a component of the conventional ‘kit of parts’ allowed for a novel investigation that recombines zero waste goals, flat-packing potential, structural expression and computational processes. This paper will expand (greatly) upon previous research into bi-chord truss designs, developing a tri-chord truss, which is parametrically linked to its structural moment diagram. The cross section of each truss is formed based on the loading condition for each beam. This truss design has been developed through a thorough series of analytical models and tests performed digitally, to scale and in full scale. The tri-chord truss is capable of resisting rotational failures well beyond the capacity of the bi-chord designs previously developed. The results are complex, and elegant expressions of structural logics embodied in a tightly constrained functional design.

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
