summary	For several years great effort has been devoted to the study of Architectural Design Optimization (ADO). However, although in the recent years ADO has attracted much attention from academia, optimization methods and tools have had a limited influence on the architectural profession. The aim of the study is to reveal users' expectations from the optimization tools and define limitations preventing wide-spread adaptation of the optimization solvers in the architectural practice. The paper presents the results of the survey "Optimization in the architectural practice" conducted between December 2015 and February 2016 on 165 architectural trainees and practising architects from 34 countries. The results show that there is a need for an interactive multi-objective optimization tool, as 78% respondents declared that a multi-objective optimization is more necessary in their practice than a single objective one and 91% of them acknowledged the need for choice of promising solutions during optimization process. Finally, it has been found that daylight, structure and geometry are three top factors which architects are interested in optimizing.

summary	The abundance of vertical surfaces in urban environments and their use for green installations have been of great interest in the architectural community. This paper discusses how vertical gardens and urban farming can be spurred on and enabled by two emerging fields of investigation: Material Science and the Internet of Things (IoT). This paper discusses how two emerging strategies, smart materials and novel sensing and actuation systems linked to the IoT, can facilitate the creation of a stable environment or zone along architectural facades for the creation of new ecosystems. Furthermore, this paper will contemplate future trajectories for the integration of living matter into buildings and propose an open source database that will facilitate the exchange of collected data and knowledge to spur on further developments.

title	De Humani Corporis Fabrica - Fabricating Emotions through Architecture
doi	https://doi.org/10.52842/conf.ecaade.2016.1.501

summary	This paper describes an experiment that took place as the last day of the elective course "De Humani Corporis Fabrica - Fabricating Emotions through Architecture". The goal of the Experiment was to evaluate the emotional experience of 1:1 scale architectural settings. The Experiment was part of the research for a PhD thesis which describes the relationship between architecture and the body since Vitruvius until the current theories of embodiment. The referred to thesis proposes the incorporation of the corporeal practices of performance art in the teaching of Architecture and combines these with the use of emotion measurement methodologies in order to evaluate the experience of architectural space and design objects during the design process. Psycho-physiological changes in the body's sensory perception during the performances were evaluated through the combined use of biometric technology (e-health platform), a Presence Questionnaire and a SAM chart. The course was attended by 4 students who participated as subjects in the Experiment. The Experiment had the technical support of the DFKI - Deutsches Forschungszentrum für Künstliche Intelligenz, which provided the machinery necessary to collect the biometric data during the Experiment and the knowledge needed to process them.

summary	In early design process, designers employ several media for externalizations of their design ideas which facilitate decision making, discussion and evaluation. Especially models are the most common representation tools and are used generally to understand and make spatial reasoning on the design ideas. Besides the traditional methods, today, the technological developments bring new ways for collaboration and design in 3D; the mobile augmented reality (MAR) technology is one of them. MAR is augmented reality technology which is provided by mobile devices. This study focuses on the early design process of collaborative designers' communication when they are working with the MAR technology. We developed a MAR environment for designers, and conducted an experiment to understand the key elements of the interaction of the designers with the interface. The communication and interaction of the designers are analyzed using the protocol analysis method. The results show that the MAR technology supports the co-design activities encouraging the designers to manipulate the created artefact. The results of the study would be indicative for future studies.

summary	It has been proposed that, after the internet age, we are now entering a new era of the '/Augmented Age/' (King, 2016). Physician Michio Kaku imagined the future of architects will be relying heavily on Augmented Reality technology (Kaku, 2015). Augmented reality technology is not a new technology and has been evolving rapidly. In the last three years, the technology has been applied in mainstream consumer devices (Coppens, 2017). This opened up possibilities in every aspect of our daily lives and it is expected that this will have a great impact on every field of consumer's technology in near future, including design and fabrication. What is the future of design and making? What kind of new digital fabrication paradigm will emerge from inevitable technological development? What kind of impact will this have on the built environment and industry? FlowMorph is a research project developed in the Bartlett School of Architecture, B-Pro AD with the collaboration of the authors and students as a 12 month MArch programme, we developed a unique design project trying to answer these questions which will be introduced in this paper.

title	Inconsistent Affective Reaction: Sentiment of Perception and Opinion in Urban Environments
doi	https://doi.org/10.52842/conf.caadria.2024.2.395

summary	The ascension of social media platforms has transformed our understanding of urban environments, giving rise to nuanced variations in sentiment reaction embedded within human perception and opinion, and challenging existing multidimensional sentiment analysis approaches in urban studies. This study presents novel methodologies for identifying and elucidating sentiment inconsistency, constructing a dataset encompassing 140,750 Baidu and Tencent Street view images to measure perceptions, and 984,024 Weibo social media text posts to measure opinions. A reaction index is developed, integrating object detection and natural language processing techniques to classify sentiment in Beijing Second Ring for 2016 and 2022. Classified sentiment reaction is analysed and visualized using regression analysis, image segmentation, and word frequency based on land-use distribution to discern underlying factors. The perception affective reaction trend map reveals a shift toward more evenly distributed positive sentiment, while the opinion affective reaction trend map shows more extreme changes. Our mismatch map indicates significant disparities between the sentiments of human perception and opinion of urban areas over the years. Changes in sentiment reactions have significant relationships with elements such as dense buildings and pedestrian presence. Our inconsistent maps present perception and opinion sentiments before and after the pandemic and offer potential explanations and directions for environmental management, in formulating strategies for urban renewal.

summary	Existing urban planning and design systems and workflows do not effectively support a fast iterative design process capable of generating and evaluating large-scale urban models. One of the key issues is the lack of flexibility in workflows to support iterative design generation and performance analyses, and easily integrate into design and planning processes. We present and demonstrate a parametric modelling system, Möbius, that can easily be linked to Geographic Information Systems for creating modular workflows, provides a novel approach for visual programming that integrates associative and imperative programming styles, uses a rich topological data structure that allows custom data attributes to be added to geometric entities at any topological level, and is fully web-based. The demonstration consists of five main stages that alternate between QGIS and Möbius, generating and analysing an urban model reflecting on site conditions and using a library of parametric urban typologies, and uses as a case study an urban design studio project in which the students sketched a set of rules that defined site coverage and building heights based on the proximity to various elements in the design.

summary	According to eCAADe's mission, the exchange and collaboration within the area of computer aided architectural design education and research, while respecting the pedagogical approaches in the different schools and countries, can be regarded as a core activity. The current session follows up on the first Contextualised Digital Heritage Workshop (CDHW) held on the occasion of eCAADe 2016 in Oulu (D. di Mascio et.al.) This event was thought to represent the first of a series of future contextualized digital heritage workshops and hence, the name Oulu interchangeable with the name of any other city or place. The second CDHW took place in the framework of CAADRIA 2017 in Suzhou (D. di Mascio & M.A. Schnabel) and focussed on sharing and dissemination of heritage information and personal experiences, such as narratives.The primary objective for the 2018 digital heritage session is to engage participants in an active discussion, not the longer format presentation of prepared positions. The round table itself is limited to short opening statements so as to ensure time is allowed for viewpoints to be exchanged and for the conference attendees to join in on the issues discussed. The panel will review past practices with the potential for guiding future direction.

summary	Brick has been used in construction since ancient times and has been respected among other tectonic materials through out the history. Novel technologies recently have opened new horizons in using brick in architectural design. This paper investigates innovative implementation of bricks in kinetic architecture. Kinetic structures usually employ complex and high-cost mechanisms to come into force and their movements might be limited to some conditions. By the use of magnet in digital design, this research examines new methods for performing simple and affordable kinetic structures so as to create interactive relations between architecture and human being. Magnetic energy is applied in two ways to move a roof made of brick which is considered a heavy and masonry material. Consequently, it represents the hidden potentials of magnet as a renewable source of energy.

summary	This paper describes some of the challenges of using a Massive Open Online Course (MOOC) framework system with a variety of digital content. Situated in the 'efficiency' paradigm of digital design methods and Computer Aided Architectural Design (CAAD) education, we allow participants to set their own schedules, meet demands that are appropriate for their abilities, and determine their own path. The content within this framework motivates students through life-like tasks and examples. This paper shares our experiences in CAAD education through a course curriculum developed by applying a variety of digital content. We have focused on resolving the problem of inefficient teaching of CAAD systems by developing a blended learning curriculum.

summary	Reviewing the current research trends in robotic fabrication around the world, the trajectory promises new opportunities for innovation in Architecture and the possible redefinition of the role of the Architect in the industry itself. New entrepreneurial, innovative start-ups are popping up everywhere challenging the traditional model of the architect. However, it also poses new questions and challenges in the education of the architect today. What are the appropriate pedagogical methods to instill enthusiasm for new technologies, materials, and craft? How do we avoid the pure application of pre-set tools, such as the use of the laser cutter has become, which in many schools around the world has caused problems rather than solving problems? How do we teach students to invent their tools especially in a society that doesn't have a strong background in the making? The primary focus of this paper is on how architectural CAAD/ CAM education through the use of robotic fabrication can enhance student's understanding, passion and knowledge of materiality, technology, and craftsmanship. The paper is based on the pedagogical set-up and method of an M. Arch I studio that was taught by the author in fall 2016 with the focus on robotic fabrication, materiality, traditional timber construction systems, tool design and digital and physical craftsmanship.

title	TopoBIM: Web-based Spatial Topology for Early Design Participation
doi	https://doi.org/10.52842/conf.ecaade.2016.2.663
source	Herneoja, Aulikki; Toni Österlund and Piia Markkanen (eds.), Complexity & Simplicity - Proceedings of the 34th eCAADe Conference - Volume 2, University of Oulu, Oulu, Finland, 22-26 August 2016, pp. 663-672
summary	TopoBIM is a 3D web-based viewer for BIM data that facilitates the capture of stakeholder knowledge related to project requirements and constraints in early design. The software provides an interface for viewing 3D models and data for selected room types and adding topological annotations. The use of topological representation is proposed as a method for facilitating knowledge capture, allowing decisions about the details of plan layout to be deferred and widening the potential for participation in the early stage design process. Topological representation is widely employed in the engineering disciplines, but is not commonly used as a means of capturing schematic information in early design. TopoBIM is proposed as a methodology and workflow for the introduction of topology in early design, and as an example of lightweight, bespoke software that informs design by allowing stakeholders to perform specific tasks using BIM data, without the constraints and limiting complexity of BIM authoring environments.

title	Using Tensegrity and Folding to Generate Soft Responsive Architectural Skins
doi	https://doi.org/10.52842/conf.ecaade.2016.1.529
source	Herneoja, Aulikki; Toni Österlund and Piia Markkanen (eds.), Complexity & Simplicity - Proceedings of the 34th eCAADe Conference - Volume 1, University of Oulu, Oulu, Finland, 22-26 August 2016, pp. 529-536
summary	This paper describes the process of designing a prototype for a soft responsive system for a kinetic building facade. The prototype uses lightweight materials and mechanisms to generate a building facade skin that is both soft (less dependent on hard mechanical systems) and responsive (dynamically and simultaneously adapting to spatial and environmental conditions). By combining concepts stemming from both tensegrity structures and folding mechanisms, we develop a prototype that changes dynamically to produce varying facade patterns and perforations based on sensor-network data and feedback. We use radiation sensors and shape memory alloys to control the prototype mechanism and allow for the required parametric adaptation. Based on the data from the radiation sensors, the lengths of the shape memory alloys are altered using electric wires and are parametrically linked to the input data. The transformation in the resulting overall surface is directly linked to the desired levels of daylighting and solar exposure. We conclude with directions for future research, including full scale testing, advanced simulation, and multi-objective optimization.

summary	When thinking about the future vision of a city, having in mind recent development in digital technologies and digital design tools we are inclined to expect new building structures which incorporate this technology to better help us manage the complexity of life, and to simplify our daily lives and tasks. The idea behind this research paper lies in design of such structures, which could be put inside an urban context and engage in creating a built environment that can add more to the quality of life. For us Interactive architecture is architecture that is responsive, flexible, changing, always moving and adapting to the needs of today. The world is becoming more dynamic, society is constantly changing and the new needs it develops need to be accommodated. As a result architecture has to follow. Spaces have to become more adaptive, responsive and nature concerned, while having the ability for metamorphosis, flexibility and interactivity. Taken as a starting point of this idea is a specific module from graduation project in 2014 "The Unexpected city", where it was possible to test out first ideas about interactive and flexible objects in an urban environment.

title	Data Transmission Opportunities for Collaborative Cloud-Based Building Information Modeling
source	SIGraDi 2016 [Proceedings of the 20th Conference of the Iberoamerican Society of Digital Graphics - ISBN: 978-956-7051-86-1] Argentina, Buenos Aires 9 - 11 November 2016, pp.907-913
summary	Collaboration within Building Information Modeling process is mainly based on file transfer while BIM data being exchanged in either vendor specific file formats or neutral format using Industry Foundation Classes (IFC). However, since the Web enables Cloud-based BIM services, it provides an opportunity to exchange data via Web transfer services. Therefore, the main objective of this paper is to investigate what features of Cloud interoperability can assist a network-based BIM data transmission for a collaborative work flow in the Architecture, Construction, and Engineering (AEC) industry. This study indicates that Cloud-BIM interoperability needs to deploy major components such as APIs, data transfer protocols, data formats, and standardization to redefine BIM data flow in the Cloud and to reshape the collaboration process.

summary	In continuation to Generative Design Methods, this paper investigates the implementation of Biomorphic Design, supported by computational techniques in undergraduate, architectural studio education. After reviewing the main definitions of biomorphism, organicism and biomimicry synoptically, we will assess the application of a modified biomorphic method on a final year, undergraduate design studio, in order to evaluate its potential and its suitability within the framework of a research led design studio, leading to an RIBA accredited Part I degree. Our research findings based on analysis of design outputs, student performance as well as moderators and external examiners reports initiate a constructive debate about accomplishments and failures of a design methodology which still remains alien to many undergraduate curricula.

title	Design Considerations Due to Scale Effects in 3D Concrete Printing
source	Parametricism Vs. Materialism: Evolution of Digital Technologies for Development [8th ASCAAD Conference Proceedings ISBN 978-0-9955691-0-2] London (United Kingdom) 7-8 November 2016, pp. 115-124
summary	The effect of scale on different parameters of the 3D printing of concrete is explored through the design and fabrication of a 3D concrete printed pavilion. This study shows a significant gap exists between what can be generated through computer aided design (CAD) and subsequent computer aided manufacturing (generally based on CNC technology). In reality, the 3D concrete printing on the one hand poses manufacturing constraints (e.g. minimum curvature radii) due to material behaviour that is not included in current CAD/CAM software. On the other hand, the process also takes advantage of material behaviour and thus allows the creation of shapes and geometries that, too, can’t be modelled and predicted by CAD/CAM software. Particularly in the 3D printing of concrete, there is not a 1:1 relation between toolpath and printed product, as is the case with CNC milling. Material deposition is dependent on system pressure, robot speed, nozzle section, layer stacking, curvature and more – all of which are scale dependent. This paper will discuss the design and manufacturing decisions based on the effects of scale on the structural design, printed and layered geometry, robot kinematics, material behaviour, assembly joints and logistical problems. Finally, by analysing a case study pavilion, it will be explore how 3D concrete printing structures can be extended and multiplied across scales and functional domains ranging from structural to architectural elements, so that we can understand how to address questions of scale in their design.

summary	This paper explains a method will be used during a workshop for constructing complex-curved geometry with quad edge panels. In this workshop, we demonstrate that quad-edge mesh data structure can efficiently be used to construct complex large shapes. With hands-on experiments, we will show a vast variety of shapes can be constructed using square, rectangular, parallelogram and extruded-line shaped panels. In addition, using a system we have recently developed to unfold polygonal mesh, we will demonstrate how desired shapes can be constructed by using laser-cut quadrilateral panels. This approach is particularly suitable to construct complicated sculptural and architectural shapes from anisotropic materials that can only be bended in one direction.

summary	This paper discusses the development of an interactive and a responsive Tangible User-Interface (TUI) for parametric and Building Information Modeling (BIM) applications. The prototypes presented in this paper utilizes physical computing systems to establish a flexible and intuitive method to engage digital design processes.The prototypes are hybrid UIs that consist of a digital modeling tool and an artifact. The artifact consists of a control system (sensors, actuators, and microcontrollers) and physical objects (architectural elements). The link between both environments associates physical objects with their digital design information to assist users in the digital design process. The integration of physical computing systems will enable the objects to physically respond to analog input and provide real-time feedback to users. The research aims to foster tangible computing methods to extend the capabilities of digital design tools. The prototypes demonstrate a method that allows architects to simultaneously interact with complex architectural systems digitally and physically.

summary	Building Performance simulation is escalating towards design optimization worldwide utilizing computational and advanced tools. Egypt has its plan and agenda to adopt new technologies to mitigate energy consumption through various sectors. Energy consumption includes electricity, crude oil, it encompasses renewable and non-renewable energy consumption. Egypt Electricity (EE) consumption by sector percentages is residential (47%), industrial (25%) and commercial (12%), with the remainder used by government, agriculture, public lighting and public utilities (4%). Electricity building consumption has many divisions includes HVAC systems, lighting, Computers and Electronics and others. Lighting share of electricity consumption can vary from 11 to 15 percent in mixed buildings as in our case study which definitely less that the amount used for HVAC loads. This research aims at utilizing shape morphogenesis on facades using geometric shape grammar to enhance daylighting while blocking longwave radiations causing heat stress. Mixed-use building operates in daytime more than night which emphasizes the objective of this study. Results evaluation is referenced to LEED v4.1 and ASHRAE 90.1-2016 window-to-wall ratio calibration and massive wall description. Geometric morphogenesis relies on three main parameters; Pattern (Geometry Shape Grammar: R1, R2, and R3), a reference surface to map from, and a target surface to map to which is the south-western façade of the case study. Enhancing Geo-morph rule is to guarantee flexibility due to the rotation of sun path annually with different azimuth and altitude angles and follow LEED V4.1 enhancements of opaque wall percent for building envelope.
