title	3Dino: Configuration for a Micro-Photogrammetric Survey - Applying Dino-Lite microscope for the digitalization of a cuneiform tablet

summary	Close-range photogrammetry, due to the possibilities offered by the technological evolution of acquisition tools and, above all, the relative original challenges posed to surveyors and the theory of measurements, deserve constant critical attention. The new opportunities to detect and represent reality are mostly focused on historical architecture, referring to consequent orders of magnitude and restitution scales. On the other hand, the formalization of relevant practices for very small objects is not frequently addressed. In recent tests carried out using two Dino-Lite handheld digital microscope models, polarized light digital microscopes generally used in medical and industrial fields, we proved the potential of using these imaging systems also for Cultural Heritage documentation, highlighting, however, some issues related to the depth of field and the consequent acquisition geometry. Therefore, this study aims to solve these problems, increasing the performance of microscopic photogrammetry by optimizing the acquisition procedures with the design of custom accessories for micro-photogrammetry (e.g. a calibrated plate). These developments will be carried out as part of a technology transfer agreement with the Dino-Lite company pointed to codify a protocol for high accuracy photogrammetric documentation of small artefacts.

summary	The integration of Robot Operating System (ROS) with Human-Machine Collaboration (HMC) currently represents the future tendency toward Autonomous Robotic In-Situ Assembly on Construction Sites. In comparison with the industrial environment, construction sites nowadays are extremely complex and unpredictable, due to the different building components and customized design.This paper presents a visual-based object recognition method and user interface enabling on-site robot arms to autonomously handle building components, to build specific designs without the influence of material, shape, and environment. The implementation is an object recognition approach that serves with KUKA industrial robotic manipulator along with an RGB-depth stereo camera in an eye-in-hand configuration to grasp and manipulate found elements to build the desired structure. Opportunities for using vision-based autonomous robotic in-situ assembly on construction sites are reviewed.

title	A Computational Approach for Optimizing the Daylighting Performance of Existing Buildings
source	Abdelmohsen, S, El-Khouly, T, Mallasi, Z and Bennadji, A (eds.), Architecture in the Age of Disruptive Technologies: Transformations and Challenges [9th ASCAAD Conference Proceedings ISBN 978-1-907349-20-1] Cairo (Egypt) [Virtual Conference] 2-4 March 2021, pp. 69-83
summary	Daylighting provision gives a significant contribution to the enhancement of the indoor visual environment and user comfort. This study aims to provide a methodology to assess and optimize daylighting performance in buildings. The paper utilizes simulation techniques for identifying the most efficient daylight performance by incorporating parametric optimization tools to enhance the daylighting performance of existing buildings. The developed workflow includes three consecutive phases. The first examines the daylighting performance of the existing building. The second phase is concerned with daylighting adequacy and the third aims to optimize the quality of light rather than just the quantity through the utilization of a simple shading system to parametrically investigate the effect of using different shading configurations on daylighting performance and to select the optimal solution. A louver system was parameterized according to a predefined process that associates its depth, count and rotation angle while a vertical screen was parametrized according to its scale and tilt angle. To examine the potentials of the proposed multi-stage method, it has been implemented on an office building located in new Cairo, Egypt. The results demonstrate that using the proposed optimization strategy drastically enhanced the Spatial Daylighting Autonomy of the building from 27% to 87% in comparison with the base case. Moreover, the optimum shading solution enhanced the daylighting quality by reducing the glare probability for better visual comfort from 60% to only 14%.

title	Inductive Creative Processes within Ideation Phases of Digital Design Products
source	Gomez, P and Braida, F (eds.), Designing Possibilities - Proceedings of the XXV International Conference of the Ibero-American Society of Digital Graphics (SIGraDi 2021), Online, 8 - 12 November 2021, pp. 463–473
summary	This article aims to identify and analyze inductive aspects (those which go from particular instances to the general configuration) present in ideation phases of digital design projects (such as apps, websites and tools for companies’ internal communications), with special emphasis on how induction occurs in creative processes. Using a qualitative methodological approach, the analysis is based on in-depth, semi-structured interviews with digital designers, on a literature review on the subjects of creativity and classic design method, as well as on a design documentary. Research findings suggest the importance of combining the use of verbal and visual communication resources in group dynamics; the need for designers to be highly proficient in the tools and techniques used while generating new alternatives, regardless of their physical/analogical or virtual/digital nature; and to allocate, whenever possible, ample time to explore ideas in order to push the limits of each project being developed.

title	Parametric Modeling as Record of Memory of Vernacular Boats

summary	This work seeks to continue the research started in 2017 about the triangle boat type, based on the traditional models of the municipality of Icapuí in Ceará / Brazil. The intention is to expand and refine the research, analyzing the construction process and the typology of the boats. For this, it is proposed to define a typology and a shape grammar of the boats and implement, in a digitally-based system, a formalized language. The methodology adopted in this work starts from a knowledge construction process following the Design Science Research strategy. The main result is an in-depth analysis of the description and representation of a vernacular design of the triangle boats. The documentation approach using parametric modeling offers great contributions to the memory and cultural heritage preservation, since an algorithmic description is able to retain information pertaining to both the material and immaterial part of the artifact.

doi	https://doi.org/10.52842/conf.ecaade.2021.1.537
summary	This research focuses on the geometric analysis of a project by the architect Marcello D'Olivo, in which the role of parametrization could be a significant part.The first phase was an in-depth study of the compositional syntax of the author, in order to understand the rules adopted by him to design architectures. As he worked between 1950 and 1990, he didn't use digital software for the computation of his projects, but only traditional instruments.The second phase was a description of digital computational procedures to generate models using parametric software. The digitization of some morphologies designed by D'Olivo was converted in shape algorithms.So the aim of the research was to convert his analog procedures into a series of well-defined digital steps, in order to systematize a way to proceed to control complex forms and to attempt to build a bridge between the pencil projects of D'Olivo and parametric design.

title	Daylight and Energy Consumption Assessment of a School Building Through Multi-Objective Optimization and Clustering Technique
source	Gomez, P and Braida, F (eds.), Designing Possibilities - Proceedings of the XXV International Conference of the Ibero-American Society of Digital Graphics (SIGraDi 2021), Online, 8 - 12 November 2021, pp. 229–239
summary	Multi-objective problems usually employ conflicting objective functions, making the Simulation-Based Optimization process return a set of solutions. This study applies a clustering technique to analyze and characterize the solutions obtained in a school building optimization problem, maximizing daylight while minimizing energy consumption. We modeled the geometry using the Rhino + Grasshopper platform, following an existing building's characteristics. The parameters were the building's dimensions, openings' height, solar devices' and light shelves' reflectance, solar devices' distance from the facade, rotation angle, and depth of light shelves. We applied a clustering technique to group solutions according to their parametric similarities at the end of the optimization process. This approach made it possible to establish guidelines to support the designer's choice of the combination of parameters that best fits his purposes.

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.

title	Augmenting Passive Actuation of Hygromorphic Skins in Desert Climates: Learning from Thorny Devil Lizard Skins
source	Abdelmohsen, S, El-Khouly, T, Mallasi, Z and Bennadji, A (eds.), Architecture in the Age of Disruptive Technologies: Transformations and Challenges [9th ASCAAD Conference Proceedings ISBN 978-1-907349-20-1] Cairo (Egypt) [Virtual Conference] 2-4 March 2021, pp. 264-278
summary	The exploitation of latent properties of natural materials such as wood in the passive actuation of adaptive building skins is of growing interest due to their added value as a low-cost and low-energy approach. The control of wood response behavior is typically conducted via physical experiments and numerical simulations that explore the impact of hygroscopic design parameters. Desert climates however suffer from water scarcity and high temperatures. Complementary mechanisms are needed to provide sufficient sources of water for effective hygroscopic operation. This paper aims to exploit such mechanisms, with specific focus on thorny devil lizard skins whose microstructure surface properties allow for maximum humidity absorption. We put forward that this process enhances hygroscopic-based passive actuation systems and their adaptation to both humidity and temperature in desert climates. Specific parameters and rules are deduced based on the lizard skin properties. Physical experiments are conducted to observe different actuation mechanisms. These mechanisms are recorded, and texture and bending morphologies are modeled for adaptive skins using Grasshopper.

title	Exploring the Self-Organizing Structure of the Moroccan Medina: A Simulation Model for Generating Urban Form
source	Abdelmohsen, S, El-Khouly, T, Mallasi, Z and Bennadji, A (eds.), Architecture in the Age of Disruptive Technologies: Transformations and Challenges [9th ASCAAD Conference Proceedings ISBN 978-1-907349-20-1] Cairo (Egypt) [Virtual Conference] 2-4 March 2021, pp. 672-685
summary	This research explores the use of generative design and computational simulations in the exploration of urban compositions based on traditional urban forms from North Africa. Upon the examination of these urban settlements, we discuss the relationship between traditional urban form and generative urbanism theory. We investigate several factors that allow these self-generated urban tissues to be highly adaptive to social, spatial, and environmental change. Following this, we formulate guidelines to reinterpret some of the characteristics of these urban forms. Built on these features, the simulation seeks to explore the generation of abstract urban forms and their optimization. In this regard, this experiment utilizes 3D and parametric design tools (Rhinoceros 3D and Grasshopper) to define a generative urban simulation and optimization model. It explores the use of algorithmic design methodology in the definition and optimization of the generated urban form. For this purpose, grid-based operations with base modules are used in conjunction with introverted urban blocks. We employ evolutionary algorithms and Pareto front methodology to visualize and rank a multitude of optimized results that are evaluated using three different and conflicting design objectives: sun exposure, physical accessibility, and urban density. The results are ranked and analyzed by comparing the outcomes of these different objective functions. The result of this study shows that it is possible to allow a degree of diversification of a myriad of urban configurations with a generative form-finding algorithm while still maintaining a rather commendable adaptability to various design constraints in the case of high-density settings. In this research, it is anticipated that an algorithmic design model is a fitting contemporary solution that can simulate the philosophy of a design made without a designer and offer a wide range of objective-based spatial solutions. It sets the stage for a discussion about the relevance of reinterpreting traditional urban forms from north Africa by designing a generative model that allows for self-organization.

summary	This research demonstrates the development of a hybrid FRP-timber wall and slab system for multi-story structures. Bespoke computational tools and robotic fabrication processes allow for adaptive placement of material according to specific local requirements of the structure thus representing a resource-efficient alternative to established modes of construction. This constitutes a departure from pre-digital, material-intensive building methods, based on isotropic materials towards genuinely digital building systems using lightweight, hybrid composite elements. Design and fabrication methods build upon previous research on lightweight fiber structures conducted at the University of Stuttgart and expand it towards inhabitable, multi-story building systems. Interdisciplinary design collaboration based on reciprocal computational feedback allows for the concurrent consideration of architectural, structural, fabrication and material constraints. The robotic coreless filament winding process only uses minimal, modular formwork and allows for the efficient production of morphologically differentiated building components. The research results were demonstrated through Maison Fibre, developed for the 17th Architecture Biennale in Venice. Situated at the Venice Arsenale, the installation is composed of 30 plate like elements and depicts a modular, further extensible scheme. While this first implementation of a hybrid multi-story building system relies on established glass and carbon fiber composites, the methods can be extended towards a wider range of materials ranging from ultra-high-performance mineral fiber systems to renewable natural fibers.

title	Embodied empathy: Using affective computing to incarnate human emotion and cognition in architecture
source	International Journal of Architectural Computing 2021, Vol. 19 - no. 4, 532–552
summary	This research aims to develop a cyber-physical adaptive architectural space capable of real-time responses topeople’s emotions, based on biological and neurological data. To achieve this goal, we integrated artificialintelligence (AI), wearable technology, sensory environments, and adaptive architecture to create anemotional bond between a space and its occupants and encourage affective emotional interactions betweenthe two. The project’s objectives were to (1) measure and analyze biological and neurological data to detectemotions, (2) map and illustrate that emotional data, and (3) link occupants’emotions and cognition to a builtenvironment through a real-time emotive feedback loop. Using an interactive installation as a case study, thiswork examines the cognition-emotion-space interaction through changes in volume, color, and light as ameans of emotional expression. It contributes to the current theory and practice of cyber-physical design andthe role AI plays, as well as the interaction of technology and empathy.

summary	House Block was a temporary housing prototype in East London, UK from April to May 2021. The project constituted the most recent in a series of experiments developing Automated Architecture (AUAR) Labs’ discrete framework for housing production, one which repositions the architect as curator of a system and enables participants to engage with active agency. Recognizing that there is a knowledge gap to be addressed for this reconfiguration of practices to take form, this project centred on making automation and its potential for local communities tangible. This sits within broader calls advocating for a more material alignment of inclusive design with makers and 21st Century making in practice (see, for example, Luck 2018). House Block was designed and built using AUAR’s discrete housing system consisting of a kit of parts, known as Block Type A. Each block was CNC milled from a single sheet of plywood, assembled by hand, and then post-tensioned on site. Constructed from 270 identical blocks, there are no predefined geometric types or hierarchy between parts. The discrete enables an open-ended, adaptive system where each block can be used as a column, floor slab, wall, or stair—allowing for disconnection, reconfiguration, and reassembly (Retsin 2019). The democratisation of design and production that defines the discrete creates points for alternative value systems to enter, for critical realignments in architectural production.

summary	The Adaptive Solar Façade (ASF) as an integrated dynamic and flexible building facade could be a hopeful design tool to provide residents comfort and energy efficiency by applying relevant integrated parametric design. Based on that, in this study, we investigated a designing process and optimization of ASF concentrating on providing the visual comfort and energy efficiency. We start with an extended summary of previous studies which has been done for developing a dynamic system correspond to origami and butterfly wings. Afterwards, we design 10 movement patterns for façade at the next stage, we simulate the Illuminance uniformity distribution and amount of energy consumption in the interior area. It should be noted that this simulation is done hourly. Therefore, 52 base models were investigated in Hamedan without using intelligent façade. It should be considered that these models are offices and they are investigated in the cold tundra in four days of the year between 6 A.M. to 6 P.M. Afterwards, 520 façade affected proposed models simulated for comparing to the base model. We have done the latter simulation using Colibri plugin while it optimized linearly. All of the datasets have been processed in an algorithm circulation for analyzing the simulations results.

summary	This work explores the relevance of photogrammetry-generated errors for contemporary architectural design. Unlike approaches featuring correction or elimination of such errors, this study demonstrates how they can be accommodated in the design process to expand its exploratory boundaries and emancipate the designer from the need of ultimate control. The work also highlights the relevance of software error explorations in the context of modern media culture theory and critical discourses on computer-generated imagery. By exploring the errors of photogrammetry, the study sought to highlight its potential as a creative exploration medium instead of a mere representation tool, using new interventions to an existing building as an experimental brief. Conducting the explorations within the philosophical framework of Jean Baudrillard's four orders of the image, and relating them to contrasting discourses, allowed to coin their most important creative and esthetic values. It revealed how surplus, leftover and undesirable data can be harnessed to provide a critical trajectory, through computation, to fields like historic preservation and adaptive reuse. The study concludes by proposing that photogrammetry errors, although distancing the digital representation from an accurate depiction of analog reality, do not deprive it of new meaning. Conversely, they generate new esthetic, spatial and functional qualities that uncover alternative, critical ways of architectural creation. Conducting error explorations in the context of philosophies debating the value of the real and hyperreal increases their discursive potential, legitimizing the agency of software errors in architectural computing.

summary	Bio-tile is a multipurpose artifact designed for protecting the coastline from erosion while creating a landscape element and an architectural experience for visitors. Bio-tile performs as a mitigation strategy to slow down erosion while promoting biodiversity. This paper describes the methodology used to develop the bio-tile as the nexus between digital and environmental for resolving coastline challenges through material tectonics. A non-linear algorithm and nature’s inherent code are used to develop the Bio-tile, a nature-based hybrid infrastructure. This approach aims to generate a performance-oriented design by using emergence theory to construct shoreline elements adaptive to climatic conditions.

summary	Utilizing existing principles of plant movement, we can design climatic-responsive facades made of hygroscopic materials. This paper investigates the use of a double actuating system to create an architectural façade. Several adaptive façade strategies have been previously developed using wood bilayers, but there has not been significant investigation into the application of multiple actuation points in a single unit. The paper presents a façade that is responsive to the surrounding environment via the kinematic amplification of hygroscopic wood expansion. The kinematic amplification uses the biomechanical principles from both the Water Lily (Nymphaea) and the Purple Shamrock (Oxalis triangularis). Acting as an adaptive shading mechanism, the façade system - arranged using Lindenmayer system principles - can improve occupant comfort by controlling solar radiation . The developed prototypes use climate-responsive wood bilayer actuators. The aesthetic and functional features of the bio-inspired mechanism promote a visual awareness between our built environment and environmental conditions.

title	The Synergy of building massing and facade - An Evo-Devo approach for performance-based design optimization combining facade design with building massing

summary	One of the problems lies in performance-based architectural design optimization is the separation of building massing design and facade design. The separation of design processes significantly weakens the synergizing of building massing and facades for more progressive performance improvement. In order to overcome this weakness, this paper presents a performance-based design optimization workflow combining facade with building massing design using an Evo-Devo approach. This workflow enables architects to make a rapid design exploration of different faÃ§ade design schemes incorporating building massing design optimization. For demonstration, a case study is presented to show how this approach can facilitate early-stage architectural design exploration, and how the combination of the two factors can outperform the results produced by separated design processes.

summary	This project develops a template design and an adaptive fabrication process for sustainable Compressed Earth Block (CEB) dwellings for low-income countries. Most existing projects (Wilton et al. 2019; WASP 2021) on sustainable dwellings involve high-tech equipment or skilled workers on-site. This project integrates digital technologies into the design and fabrication processes to reduce these requirements and make the design compatible with conventional construction methods that are actively adopted in low-income countries using minimum infrastructure, skilled labor, and investment.
