summary In order to support exploration in the early stages of the design process, researchers have proposed the use of population-based multi-objective optimisation algorithms. This paper focuses on analysing the resulting population of design variants in order to gain insights into the relationship between architectural features and design performance. The proposed analysis method uses a combination of k-means clustering and Archetypal Analysis in order to partition the population of design variants into clusters and then to extract exemplars for each cluster. The results of the analysis are then visualised as a set of charts and as design models. A demonstration of the method is presented that explores how self-shading geometry, envelope materials, and window area affect the overall performance of a simplified building type. The demonstration shows that although it is possible to derive general knowledge linking architectural features to design performance, the process is still not straightforward. The paper ends with a discussion on how the method can be further improved.

title Parametric environment for internalization and classification of models generated by the Shap-E tool

summary Computing has been increasingly employed in design environments, primarily to perform calculations and logical decisions faster than humans could, enabling tasks that would be impossible or too time-consuming to execute manually. Various studies highlight the use of digital tools and technologies in diverse methods, such as parametric modeling and evolutionary algorithms, for exploring and optimizing alternatives in architecture, design, and engineering (Martino, 2015; Fagundes, 2019). Currently, there is a growing emergence of intelligent models that increasingly integrate computers into the design process. Demonstrating great potential for initial ideation, artificial intelligence (AI) models like Shap-E (Nichol et al., 2023) by OpenAI stand out. Although this model falls short of state-of-the-art sample quality, it is among the most efficient orders of magnitude for generating three-dimensional models through AI interfaces, offering practical balance for certain use cases. Thus, aiming to explore this gap, the presented study proposes an innovative design agency framework by employing Shap-E connected with parametric modeling in the design process. The generation tool has shown promising results; through generations of synthetic views conditioned by text captions, its final output is a mesh. However, due to the lack of topological information in models generated by Shap-E, we propose to fill this gap by transferring data to a parametric three-dimensional surface modeling environment. Consequently, this interaction's use aims to enable the transformation of the mesh into quantifiable surfaces, subject to collection and optimization of dimensional data of objects. Moreover, this work seeks to enable the creation of artificial databases through formal categorization of parameterized outputs using the K-means algorithm. For this purpose, the study methodologically orients itself in a four-step exploratory experimental process: (1) creation of models generated by Shap-E in a pressing manner; (2) use of parametric modeling to internalize models into the Grasshopper environment; (3) generation of optimized alternatives using the evolutionary algorithm (Biomorpher); (4) and classification of models using the K-means algorithm. Thus, the presented study proposes, through an environment of internalization and classification of models generated by the Shap-E tool, to contribute to the construction of a new design agency methodology in the decision-making process of design. So far, this research has resulted in the generation and classification of a diverse set of three-dimensional shapes. These shapes are grouped for potential applications in machine learning, in addition to providing insights for the refinement and detailed exploration of forms.

summary A generative description of Mies van der Rohe's courthouse language is presented in the form of a shape grammar. The grounding of the work is based on a set of 135 sketches produced by the office of Mies during the design process of the Everett McKinley Dirksen United States Courthouse in Chicago, and documented in the Mies van der Rohe Archive at the Museum of Modern Art. The work here postulates a set of 39 unique courthouse designs all showcasing distinct variations of the courtroom type in the Miesian language and re-casts them in two-dimensional diagrams to make their differences and similarities transparent. A series of spatial relations between five types of spaces are extracted, including courtrooms, circulation networks, vertical cores, office spaces, and support spaces, and are deployed to specify the shape rules of the grammar. A set of conventions to specify how the two-dimensional diagrams represent three-dimensional models is briefly outlined to prepare the ground for the implementation of the grammar in a three-dimensional shape grammar interpreter.

summary Since 1985 the Computer-Aided Architectural Design Futures Foundation has fostered high level discussions about the search for excellence in the built environment through the use of new technologies with an exploratory and critical perspective. In 2015, the 16th CAAD Futures Conference was held, for the first time, in South America, in the lively megalopolis of Sao Paulo, Brazil. In order to establish a connection to local issues, the theme of the conference was "The next city". The city of Sao Paulo was torn down and almost completely rebuilt twice, from the mid 1800s to the mid 1900s, evolving from a city built in rammed-earth to a city built in bricks and then from a city built in bricks to a city built in concrete. In the 21st century, with the widespread use of digital technologies both in the design and production of buildings, cities are changing even faster, in terms of layout, materials, shapes, textures, production methods and, above all, in terms of the information that is now embedded in built systems.Among the 200 abstracts received in the first phase, 64 were selected for presentation in the conference and publication in the Electronic Proceedings, either as long or short papers, after 3 tough evaluation stages. Each paper was reviewed by at least three different experts from an international committee of more than 80 highly experienced researchers. The authors come from 23 different countries. Among all papers, 10 come from Latin-American institutions, which have been usually under-represented in CAAD Futures. The 33 highest rated long papers are also being published in a printed book by Springer. For this reason, only their abstracts were included in this Electronic Proceedings, at the end of each chapter.The papers in this book have been organized under the following topics: (1) modeling, analyzing and simulating the city, (2) sustainability and performance of the built environment, (3) automated and parametric design, (4) building information modeling (BIM), (5) fabrication and materiality, and (6) shape studies. The first topic includes papers describing different uses of computation applied to the study of the urban environment. The second one represents one of the most important current issues in the study and design of the built environment. The third topic, automated and parametric design, is an established field of research that is finally becoming more available to practitioners. Fabrication has been a hot topic in CAAD conferences, and is becoming ever more popular. This new way of making design and buildings will soon start affecting the way cities look like. Finally, shape studies are an established and respected field in design computing that is traditionally discussed in CAAD conferences.

summary The approach of contemporary architecture with urban environment has always been in perpetual evolution. The path between concept and real building has been driven since ancient times by traditional drawing tools which discretized the architect ideas into shapes. The cases studied for morphogenesis evolution, featured in the top-notch architectural firms, have been framed into two different strategies. In the first family the shape is created by the modifications of several distinct geometrical elements, which create formal complexity. In the second family of buildings the complexity is the result of very few geometrical elements, whose morphogenetic process generates complex forms. As the geometrical elements decrease in number, the draft shape must undergo a deeper process of modification to solve the functional, sustainability and structural issues.

title Accuracy and Ambiguity: Geometric reconstruction of a seventh century stone temple in Hanchey, Cambodia
source The next city - New technologies and the future of the built environment [16th International Conference CAAD Futures 2015. Sao Paulo, July 8-10, 2015. Electronic Proceedings/ ISBN 978-85-85783-53-2] Sao Paulo, Brazil, July 8-10, 2015, pp. 190-202.
summary Modeling the fragmented and heavily eroded remains of early temple architecture poses several challenges in accurate reconstruction of shape and form from digitally acquired datasets. This paper describes a collection of stepwise ad-hoc modeling methods that can re-assemble ambiguous and fragmentary evidence to provide a robust and empirical platform for the reconstruction of ruined temples. The paper presents the results of the method and the degree of accuracy and ambiguity in the acquisition, processing and reconstruction phases. A key aspect of the method is the maintenance of multiple “ground truths” from plural sources of partial evidence. Key findings of the paper demonstrate early results from the manipulation of geometric modeling primitives based on point collections, an advance in extending the classical tools of architectural analysis and comparison. The problem of accuracy and ambiguity in these methods and their algorithmic implementation is the subject of further investigation.

summary Biological life manifests in space through a large diversity of physical structures perfectly bind and identifiable in the environment. This reveals that all share a common generative design process which allows them the same physical identity in all the shapes that generates, The human ecological design process used in architecture is not able yet to reach this design identity neither the spontaneous integration associates to it. Why? Because the geometrical design process used in ecological architecture and living structures are not similar. Thus, this paper proposes, through the identification of some geometrical characteristics from the growth mechanism of living structures, a process of shape generation through shape grammar. With this generation process is possible to generate, only in geometrical terms, a large diversity of architectural models with a common identity, that reveals some geometrical characteristics of spatial integration that living structures share with the surround environment.

summary This work studies the Performance-Based Design approach, focusing exclusively on cost performance, asking how to launch the architectural portion thinking of the cost of the building in a way that such performance can directly influence the project design and architectural form and how can shape, type and structure of the building influence the final cost of the work. For this, we chose to analyze the DProfiler software for the development of models in order to produce an architectural form that directly meets the performance cost requirements, following specified formal language, which aligns cost and project intention in the initial phase of the design. The research showed that the use of Macro BIM software platform is promising and that the generative design process can and should arise from an organization of the parts and not from predefining it as a whole, achieving an architectural project that is attainable and more sustainable.

summary A shape grammar-based computational system for chair design is presented. The paper focuses on the development of a methodology for modelling the definition stage of the design process. It is achieved by incorporating a specific grammar into a generic grammar to assist the designer in the convergence activities during the definition stage. Both grammars and their respective implementations were previously developed by different authors. The purpose is to enable the generation of a generic design solution that encompasses characteristics of a specific style, thus permitting subsequent exploration in the development stage.

title A Symbiotic Interaction of Virtual and Physical Models in Designing Smart Building Envelope

summary The building needs to be designed to minimize its environmental footprint and to be sufficiently adaptive to changing indoor and outdoor environmental conditions. The smart building envelope is an interactive system which is adaptive to environmental conditions by transforming its shape and functions. This is a kind of machine, not like a traditional building component, which should be based on integrated engineering design methods in addition to the exploration of formal aesthetics. As artistic genius or technical skill alone cannot not fully support the design of such a novel product, the design needs to be systemized by introducing a product development method such as prototyping in other industries. Prototyping needs to be integrated in school environment, even if it requires fundamental reconfiguration of current computer-based design studios. This paper aims at proposing a teaching methodology for educating the prototyping-based design of smart building envelope system in digital design studio. This methodology allows novice designers to operate interactions between virtual-physical models. And sketches are used to share ideas to other collaborators such as programming, mechanical operations without technical knowledge. The interactions between virtual-physical models and sketches contribute to not only complement virtual models and physical models, but also achieve high-performance of smart building envelope practically.

title Shape Grammars for architectural design: The need for reframing

summary Although many shape grammars and corresponding implementations have been proposed, shape grammars are not widely adopted by architectural designers. In this paper, we therefore look for the barriers of implementing and using shape grammars for architectural design. We do this by outlining several implementation strategies of shape grammars, we briefly point to our own graph-based design grammar system, and we analyse the resulting overview using theories on how designers think and act upon incoming information. Based on this analysis, we develop and suggest how design grammars might best be implemented and used for architectural design relying on the information technologies available at this particular moment of time.

summary Thermocatalytic Metafolds comprises a paper-based fabrication process that initiates ascetic self-assembly via heat application. Metafolds utilizes a composite material of paper with a selectively applied shape-changing polymer crafted via a multi-step computational, two-dimensional drafting fabrication method. Upon heat application, the paper self-folds into predetermined, three-dimensional, highly accurate, rigid shapes. The final product maintains a notable resilience to alteration, and the stringency of form serves as a testament to the process’ potential to transform the ways in which design is undertaken. This exploration of material properties has cumulated in a process that demonstrates a design based on a detailed understanding of how the composite material behaves under specific conditions.

summary Description grammars represent a formalism for generating verbal descriptions of designs, used in conjunction with shape grammars. A description grammar constitutes a set of description rules that define a language of descriptions. A description grammar interpreter implements the mechanisms to interpret descriptions and description rules, apply description rules to descriptions to derive new descriptions, and generate the members of the corresponding language of descriptions. In this paper, we argue the need for the development of a (general) description grammar interpreter, offer a formal notation for descriptions and description rules, describe the representation and implementation of descriptions and description rules, and provide an example implemented using the description grammar interpreter.

summary Shape grammars provide a concise and computable framework for design space exploration. An important aspect of design space exploration, especially in the case of grammar-based exploration of visual languages, is the ability to modify grammar rules in order to reach design solutions that are not in the scope of the initial grammar. In this paper, we describe and implement a semi-automatic approach for the 'on-the-fly' generation of new rules. In particular, new rules are added to a shape grammar by manually modifying the current shape in the derivation. This approach might enable a more agile exploration of the design space. Also, we demonstrate a proof-of-concept of the proposed approach based on an existing graph-theoretic framework for the computer implementation of shape grammars.

summary The paper presents a research on real-time shape exploration employing analogue and digital form-finding and concludes with a proposal for a teaching methodology that led to an intensive student workshop which took place at Graz University of Technology during 2014. The aim was to experiment with analogue and digital tools in parallel, counter-informing the design process. The experiments involved physical form-finding following the tradition of Frei Otto at the Institute of Lightweight Structures in Stuttgart as well as computational form-finding employing mainly dynamic relaxation techniques of spring-particle systems. The combination of techniques and methodologies eventually led to a feedback loop across different media that explored both qualitative and quantitative characteristics of the projects at hand. By establishing feedback between digital media and physical prototypes, the creative process is immediately informed by the material characteristics and properties which in turn give rise to a real-time exploration of form.Simulations of physical forces for architectural form generation are increasingly gaining ground in architectural education as there is a broad selection of computational tools readily available that allow quick experiments to be conducted.

summary Existing performance-based design exploration methods typically suffer from a lack of real-time feedback and a lack of actionable feedback. This paper proposes a hybrid design exploration method that overcomes these issues by combining parametric modelling, surrogate modelling, and evolutionary algorithms. The proposed method is structured as a mixed-initiative approach, in which parametric modelling is the key to creating a synergistic relationship between the architect and the computational system. Surrogate-based techniques will address the issue of real-time feedback, the evolutionary exploration techniques will address the issue of actionable feedback. As a first stage in developing the PEX method, this paper reports on two experiments conducted to identify an appropriate surrogate modelling technique that is efficient and robust.

summary The complexity of today´s architecture solutions brings the need to integrate, in the design process, digital tools for creation, visualization, representation and evaluation of design solutions. This paper proposes the adoption of a new Virtual Reality (VR) tool, referred to as VIARmodes, to support the architectural design process with an improved communication across different specialities, towards the facilitation of the project decision process. This tool allows a complete visualization of the design, specifically useful during the detailed design phase, including the architecture design and of other engineering specialities, progressively and interactively adapting the project visualization to the information needed for each discipline. With a set of 3 different visualization modes simulated in real scale within a Virtual Environment (VE), and adopting natural human-computer interaction by using speech, the system allows a team of architect and engineers, to visualize and interact with the proposed design during a collaborative design brief. We carried a usability evaluation study with 12 architects. The study showed that the tool was perceived to be effective and its use efficient during the design process, especially during the detailed design phase.

summary The construction and building sector is now widely known to be one of the biggest energy consumers, carbon emitters, and creators of waste. Some architectural agendas for sustainability focus on energy efficiency of buildings that minimize their energy intake during their lifetime - through the use of more efficient mechanical systems or more insulative wall systems. One issue with these sustainability models is that they often ignore the hierarchy of energy within architectural design. The focus on the efficiency is but one aspect or system of the building assembly, when compared to the effectiveness of the whole, which often leads to ad-hoc ecology and results in the all too familiar “law of unintended consequences” (Merton, 1936). As soon as adhesive is used to connect two materials, a piece of trash is created. If designers treat material as energy, and want to use energy responsibly, they can prolong the lifetime of building material by designing for disassembly. By changing the nature of the physical relationship between materials, buildings can be reconfigured and repurposed all the while keeping materials out of a landfill. The use of smart joinery to create building assemblies which can be disassembled, has a milieu of new possibilities created through the use of digital manufacturing equipment. These tools afford designers and manufacturers the ability to create individual joints of a variety of types, which perform as well or better than conventional systems. The concept of design for disassembly is a recognizable goal of industrial design and manufacturing, but for Architecture it remains a novel approach. A classic example is Kieran Timberlake's Loblolly House, which employed material assemblies “that are detailed for on-site assembly as well as future disassembly and redeployment” (Flat, Inc, 2008). The use of nearly ubiquitous digital manufacturing tools helps designers create highly functional, precise and effective methods of connection which afford a building to be taken apart and reused or reassembled into alternative configurations or for alternative uses. This paper will survey alternative energy strategies made available through joinery using digital manufacturing and design methods, and will evaluate these strategies in their ability to create diassemblable materials which therefore use less energy - or minimize the entropy of energy over the life-cycle of the material.
