title	Some Notes on the Incompleteness Theorem and Shape Grammars
source	Global Design and Local Materialization[Proceedings of the 15th International Conference on Computer Aided Architectural Design Futures / ISBN 978-3-642-38973-3] Shanghai, China, July 3-5, 2013, pp. 368-376.
summary	The paper presents a critique of the Shape Grammar paradigm viewed through the lens of the incompleteness theorem of Gödel. Shape Grammars have been extensively researched through many lenses. Their productive systemic nature was the focus of the first papers along with more recent treatises in the field while their use in analysis of known building styles has been extensive and a proven mechanism for style analysis. It is surprising though that use of Shape Grammars in actual design in practice however has been minimal. The architectural community has not actively used the paradigm in the design of real buildings, probably because of the rigid analytical approach to style and rules, following from the academic analysis that the paradigm has been subjected to. However I propose that there is another underlying reason, other than the rigid approach to construct a Shape Grammar. The nature of the concurrent application and creation of the rules lies close to the incompleteness theorem of Gödel, that uses a multitude of Turing Machines to prove that a from a set of True Axioms -A- we will never be able to determine if all sentences are true, without having to invent new axioms, outside the initial set -A-, thus unproven in terms of their true or false nature. Negation of this possibility drives us to the conclusion that true Design can never be feature -complete and thus can never be placed in a trusted framework that we all agree or believe it to be the complete truth.

title	Tree-Structure Canopy:A Case Study in Design and Fabrication of Complex Steel Structures using Digital Tools
source	International Journal of Architectural Computing vol. 11 - no. 1, 87-104
summary	This paper describes and reflects on the design and manufacturing process of the Tree-Structure canopy for the WestendGate Tower in Frankfurt upon Main, completed early 2011.The project investigated fabrication and assembly principles of complex steel structures as well as the integration of contemporary computational design, engineering, optimization and simulation techniques in a collaborative design approach. This paper focuses on the notion of modular standardization as opposed to non standard customized components. It also engages with issues relating to digital production tools and their impact on construction cost, material performance and tolerances. In addition it examines the reconfiguration of liability during a planning and construction process, an aspect which can be strongly determined by fabrication companies rather than the architect or designer.This paper is written as a reflection on the complete building process when contemporary digital tools are used from design through to fabrication. It studies both the generation of the steel structure as well the ETFE cushion skin. It reports on a collaborative project, where the main author was responsible for the canopies design, parameterization, digitalization and fabrication, as well as for the dissemination of the outcomes and findings during the design and realization process.As such it represents an example of research through design in a contemporary and evolving field.The canopy received a design award by the Hellenic Architecture Association.

summary	This research explains the development process of a design tool that can construct complex surface geometries using only two-dimensional plan drawings. The intention behind this tool is to address certain complex behavior of surface geometries such as hydrological characteristics. This paper briefly explains the historic and mathematic description of surface data structures, according to Cayley, Maxwell and Morse. This is followed by a brief introduction of the surface network/critical graph extraction technique in GIS. Additionally, the algorithm of contour extraction from asimple critical graph to reconstruct a surface is explained. In the final section the lessons learnedfrom the previous sections are used to develop algorithms for a tool which uses only plan drawings to construct complex surfaces. Three algorithms are explained in the final section among which the third one is considered to be the most complete and promising approach. Therefore,some design examples are presented to show the flexibility of the tool. At the end, this paper provides suggestions and discussions to reflect further ideas in order to improve the tool in future.

title	Augmented Reality Assisted Robotic: Tube Bending
source	ACADIA 2023: Habits of the Anthropocene: Scarcity and Abundance in a Post-Material Economy [Volume 2: Proceedings of the 43rd Annual Conference for the Association for Computer Aided Design in Architecture (ACADIA) ISBN 979-8-9891764-0-3]. Denver. 26-28 October 2023. edited by A. Crawford, N. Diniz, R. Beckett, J. Vanucchi, M. Swackhamer 340-349.
summary	The intent of this research is to study potential improvements and optimizations in the context of robotic fabrication paired with Augmented Reality (AR), leveraging the technology in the fabrication of the individual part, as well as guiding the larger assembly process. AR applications within the Architecture, Engineering, and Construction (AEC) industry have seen constant research and development as designers, fabricators, and contractors seek methods to reduce errors, minimize waste, and optimize efficiency to lower costs (Chi, Kang, and Wang 2013). Recent advancements have made the technology very accessible and feasible for use in the field, as demonstrated by seminal projects such as the Steampunk Pavilion in Tallinn, Estonia (Jahn, Newnham, and Berg 2022). These types of projects typically improve manual craft processes. They often provide projective guidelines, and make possible complex geometries that would otherwise be painstakingly slow to complete and require decades of artisanal experience (Jahn et al. 2019). Building upon a previously developed robotic tube bending workflow, our research implements a custom AR interface to streamline the bending process for multiple, large, complex parts with many bends, providing a pre-visualization of the expected fabrication process for safety and part-verification purposes. We demonstrate the utility of this AR overlay in the part fabrication setting and in an inadvertent, human-robot, collaborative process when parts push the fabrication method past its limits. The AR technology is also used to facilitate the assembly process of a spatial installation exploring a unique aesthetic with subtle bends, loops, knots, bundles, and weaves utilizing a rigid tube material.

summary	This paper presents a pilot project, using mobile devices in a History of Art and Architecture classroom to enhance instructor-student classroom interactions and student learning. At our Faculty of Architecture this particular class has a usual high failure rate (26% F in 2012). It is a compulsory course for architecture students, some of them are required to take this course twice or more before they can graduate. Traditional learning is lecture-based, and students studying toward their tests are often overloaded with information. In June 2013, Rangsit University initiated a new policy to provide tablets to every freshmen; around 7,200 tablets were distributed campus-wide (Samsung Galaxy Note 10.1 with S-pen). Toward the end of the class, the students were asked to complete a questionnaire in order to find out what they think about mobile learning. Typically, students are quite satisfied, and give positive feedback in their comments. The experience gained from this pilot project will be extended to other classes.

summary	The BIM software (Building Information Modeling) enables a holistic model -a complete description of the model-building for a complete analysis and validation prior to build, as well as the plotting of final design in architecture and its subsequent maintenance. Users can extend virtually unlimited capabilities. For this reason we have chosen a BIM with programmability by the user to create a calculation module to validate, the heat transfer and possible condensation on both walls and ceilings. The Revit Architecture BIM was chosen using the API (application programming interface) in C#. In this paper, we analyze the experience gained and the results achieved. The objective is to create a calculation and graphing module thermal transmission and condensation.

summary	Public transport interchanges often involve several stakeholders for planning and decision-making. As a result complexity leads to inefficient processes, leading to indecision, disruption, or costly delays. Consequently, the paper focuses on the application of tools for navigation and prioritization of opportunities in the need finding, fuzzy-front end, or mystery phase as introduced by Martin (2009). The paper outlines in a case study how a multi-stakeholder platform can progress from complete ambiguity in project definition through to clearly defined and understood projects that have a shared intent across the multi-stakeholder platform. These tools have been applied in a public transport context, by demonstrating the process of integrating digital innovation into various stakeholders through a participatory research process. The paper introduces the research background; discusses the hypothesis; outlines the case study; emphasizes its significance for multi-stakeholder decision-making and discusses the opportunities for the built environment.

summary	This paper proposes an architectural system interactive to both users and the environmental condition in real-time. While nature acts as a global control for the system, the user can alter it locally. Due to the increasing digitization of our contemporary culture, there is an unprecedented capacity for information to flow in our physical and socially net-worked world that can be used to inform design problems and processes. Live and real-time information sources, like Twitter, could be virtually scanned for specific data input associated to a par-ticular geometrical manipulation. This process enables a collective group of users to inform the system. As the number of users increases there is collaboration for defining the form which is different from single user interaction. Since the model is associated with a specific definition of generative behaviours as described by the words, these definitions could be used as the

summary	This paper presents a research on the use of shape grammars as an analytical tool in the history of architecture. It evolves within a broader project called Digital Alberti, whose goal is to determine the influence of De re aedificatoria treatise on Portuguese Renaissance architecture, making use of a computational framework (Krüger et al., 2011).Previous work was concerned with the development of a shape grammar for generating sacred buildings according to the rules textually described in the treatise. This work describes the transformation of the treatise grammar into another grammar that can also account for the generation of Alberti’s built work.

summary	Tomorrow’s architects will need to deal more confidently and skillfully with scientific and technological innovations in their field, e.g., parametric design, building physics, construction robotics, home automation, etc. Architecture students today must understand how things work and absorb some of the basic principles and techniques involved in their design, construction or operation. Now students need to build back some of that analytical, logical, critical, and analogical thinking that may have atrophied due to a traditional architectural education. Playing with toy construction kits for building automatic control and mobile robot models, does the job without losing the architect´s approach and attitude.

summary	Applying the method of "Land-Use Mix" (Amindabari et al. (2013)) and Focusing on changes in highly mixed land use areas within an extensive survey area and detailed analytical unit, the analysis in this study revealed some trends of distribution of mixed land use areas and their declining patterns in the eastern part of Saitama Prefecture, Japan. For example, among the changing land use patterns of Highly-Mixed-Points-as-of-1994, the pattern that a decreasing mixture index was associated with increasing residential land and decreasing commercial land occurred most often, and the points that changed with that pattern accounted for about 32% of all the Highly Mixed Points, and about 51% of the decrease in mixture index points.

summary	This paper investigates the impact of evolving building documentation methods on architectural education, focusing on historic preservation. It traces the significance of building surveys back to the 16th century when Giorgio Vasari emphasized the importance of measuring and drawing. Digital tools have shifted this paradigm from traditional methods to integrated digital 2D and 3D survey models. The research examines two case studies of historic tombstone surveys from 2013 and 2023, analyzing how students engaged with different technologies and pedagogical approaches. The 2013 study used analog-to-digital methods, allowing students to develop measuring and documentation skills through hands-on experience. The 2023 study employed digital-to-interactive methods, using photogrammetry and mobile applications for 3D modeling. These educational exercises demonstrated varying degrees of creativity and interpretative analysis, reinforcing experiential learning frameworks. Results suggest that while digital tools enhance efficiency and visualization quality, they may also diminish critical inquiry and reflection among students. This study contributes to understanding how technology reshapes architectural education practices, urging the development of curricula that balance technical proficiency with creative and analytical engagement.

summary	As architectural design methodologies focus increasingly on the production of dynamic form, the means to actuate these forms, the input that fuels parametric processes, analytical form-generating techniques and responsive controls is of primary concern. In the virtual test beds where systems are developed, inputs are often ad-hoc, based on crude assumptions of the environment, or disconnected from the physical environment entirely.Inverting a technique originally developed to illuminate virtual objects with light captured from real (physical) environments, this project explores image-based lighting as a means of detailed environmental light sensing. The objective of the project is to demonstrate the application of High Dynamic Range (HDR) image data acquired continuously in the physical world as signal input to inform, actuate and evaluate responsive solar control and daylighting systems. As a proof of concept, a virtual hemispherical dome consisting of 145 apertures is controlled to respond in real time to continuous image-based measurements of sky luminance, seeking a defined set of daylighting and solar control objectives. The paper concludes by discussing the implications of incorporating real-world environmental data in the development of dynamic form.

summary	In the field of Contemporary Esthetics is resumed the question of what is art and which are the readability conditions (reading). The questions relate to the displacement between representation and experimentation, beauty and esthetic experience, among others. In this context, we address the technology of poetry (Nancy (2012 [2013]) as technological exhibition that lets your experience the being of the object and become subjects. The corpus includes film and video (Kopystiansky 1996-97; Alys 2011 y Jaar 2013). The objective is to outline an analytical framework for thinking about the esthetic freedom of creation and the practical freedom of their recognition. (Wagner 2004).

doi	https://doi.org/10.52842/conf.acadia.2020.1.574
summary	This paper provides a state-of-the-art of computational fluid dynamics (CFD) in the building industry. Two methods were used to find this new knowledge: a series of interviews with leading architecture, engineering, and software professionals; and a series of tests in which CFD software was evaluated using comparable criteria. The paper reports findings in technology, workflows, projects, current unmet needs, and future directions. In buildings, airflow is fundamental for heating and cooling, as well as occupant comfort and productivity. Despite its importance, the design of airflow systems is outside the realm of much of architectural design practice; but with advances in digital tools, it is now possible for architects to integrate air flow into their building design workflows (Peters and Peters 2018). As Chen (2009) states, “In order to regulate the indoor air parameters, it is essential to have suitable tools to predict ventilation performance in buildings.” By enabling scientific data to be conveyed in a visual process that provides useful analytical information to designers (Hartog and Koutamanis 2000), computer performance simulations have opened up new territories for design “by introducing environments in which we can manipulate and observe” (Kaijima et al. 2013). Beyond comfort and productivity, in recent months it has emerged that air flow may also be a matter of life and death. With the current global pandemic of SARS-CoV-2, it is indoor environments where infections most often happen (Qian et al. 2020). To design architecture in a post-COVID-19 environment will require an in-depth understanding of how air flows through space.

summary	In order to design adaptable systems, the requirements include flexible models to generate a range of alternative configurations, analytical engines to evaluate performance, and well-defined selection criteria to identify suitable options. In most cases, design processes driven by performance concentrate on environmental or structural parameters; fabrication often remains disconnected from the generative process. Nonetheless, as design-to-fabrication methods become more robust, it is possible to extend the digital process to introduce fabrication variables to the definition of the project. The main focus of the research presented in this paper is the development of a digital and material workflow that connects design, structural and climate-specific topics (such as sun lighting and water drainage) toward producing a range of efficient structural and spatial assemblies.A case study serves as the main support for this investigation. Miguel Fisac’s “bones” is a light-weight roof system developed during the 1960’s, which had a very well-calibrated structural, natural-lighting, drainage and construction performance, as well as a highly refined spatial output. The system, despite its intelligence, lacked the flexibility possible today: using digital technologies, it can adapt to a significantly wider range of applications. Using “bones” as a starting point, this research develops a design-to-fabrication workflow that attempts to move forward tools, material systems and processes to enable an adaptable tectonic system.This paper describes the background research, concept, form-finding, construction process, methodology, results and conclusions of the investigation.

summary	A rigid spatial structure represents a three-dimensional structural system in which the size of the singular planar elements is very small related to the whole construction. In this paper we will do investigations of quadrilateral patterns and we will propose an analytical method for designing structural rigid folding with quadrilateral patterns following geometrical surfaces of different topology. Our method offers folding structures with four fold lines meeting in one node which allows a simpler solution of join connections and assembling of the whole spatial and structural system. As the physical characteristics of paper can lead to all kinds of wrong conclusions it is necessary to use CAD tools in addition to scale models, where the entire folding element is reconstructed and its geometric characteristics are controlled. This kind of control reflects on the scale model. Models are then adjusted, examined and built to reach certain conclusions that are once more tested in CAD software.

summary	The way people navigate through spaces has been studied for quite a while. Different models have been described and validated through empirical studies.This paper explores the use of such models in an ‘inverse design’ (Faucher and Nivet, 2000) process, applying available metaheuristic-solvers. More detailed, it showcases the description of an ambiguous fitness function as base to invent a new circulation pattern. As such technics are time consuming compared to the use of readily available patterns, an attempt is made to analyse and understand the invented circulation patterns, in order to come up with a procedural algorithm that would generate circulation pattern with the same characteristics.

summary	This paper presents preliminary results from a pilot protocol study of the cognitive behavior differences of designers in a parametric design environment and a traditional geometry modeling environment. The aim is to explore the impact of the rule algorithm feature in parametric design by comparing designers’ behavior in these two design environments. Three architects participated in the experiment in which each of them was required to complete two design sessions, one in each environment. The protocols are coded using the function-behavior-structure (FBS) coding scheme. Preliminary results show that the overall behavior is not significantly affected by the environment; however, there are significant differences at different design stages in the two design environments.
