title Deep generative modeling tasks: Automatic generation of building facades with Pix2Pix GAN for Hong Kong city expansion and renovation
source García Amen, F, Goni Fitipaldo, A L and Armagno Gentile, Á (eds.), Accelerated Landscapes - Proceedings of the XXVII International Conference of the Ibero-American Society of Digital Graphics (SIGraDi 2023), Punta del Este, Maldonado, Uruguay, 29 November - 1 December 2023, pp. 137–148
summary Hong Kong's rapid urbanization and expansion have resulted in a high incidence of new urban construction projects as well as building renovation and restoration activities. The above architectural activities in the city are characterized by inconsistency in design styles and inconsistency with the neighborhood environment. The proposal of a self-weakening design style of different designers in the same neighborhood should be taken as a practical consideration at the early stage of design. In this research, a dataset of old building facades in Hong Kong is provided, and the method of training a deep convolutional neural network is used to realize the coupling of Pix2Pix GAN algorithm to the whole or local design generation of building facade in Hong Kong. Moreover, a trained network based on the architectural styles of Hong Kong is provided with 160 sets of collected original image datasets of Hong Kong building facades for organizing pre-calibration. It classifies the elemental information of complex building facades for later training of the network and automatic generation to give new construction and renovation schemes a replicable technical route.

title Research on the Exploration of Sprayed Clay Material and Modeling System

summary As a traditional building material, clay has been used by humans for a long time. From early civilisations, to the modern dependence on new technologies, the craft of clay making is commonly linked with the use of moulds, handmade creations, ceramic extruders, etc. (Schmandt and Besserat, 1977). Clay in the form of bricks is one of the oldest building materials known (Fernandes et al, 2010). This research expands the possibilities offered by standardised bricks by testing types of clay, forms, shapes, porosity, and structural methods. The traditional way of working with clay relies on human craftsmanship and is based on the use of semi-solid clay (Fernandes et al., 2010). However, there is little research on the use of clay slurry. With the rise of 3D printing systems in recent years, research and development has been emerging on using clay as a 3D printing filament (Gürsoy, 2018). Researchers have discovered that in order for 3D-printed clay slurry to solidify quickly to support the weight of the added layers during printing, curing agents such as lime, coal ash, cement, etc. have to be added to the clay slurry. After adding these substances, clay is difficult to be reused and can have a negative effect on the environment (Chen et al., 2021). In this study, a unique method for manufacturing clay elements of intricate geometries is proposed with the help of an internal skeleton that can be continuously reused. The study introduces the process of applying clay on a special structure through spraying and showcases how this method creates various opportunities for customisation of production.

title Fabrication of Complex Clay Structures Through an Augmented Reality Assisted Platform
doi https://doi.org/10.52842/conf.caadria.2023.1.413
source Immanuel Koh, Dagmar Reinhardt, Mohammed Makki, Mona Khakhar, Nic Bao (eds.), HUMAN-CENTRIC - Proceedings of the 28th CAADRIA Conference, Ahmedabad, 18-24 March 2023, pp. 413–422
summary The relationship between clay manufacturing and architectural design has a long trajectory that has been explored since the early 2000s. From a 3D printing or assembly perspective, using clay in combination with automated processes in architecture to achieve computational design solutions is well established. (Yuan, Leach & Menges, 2018). Craft-based clay art, however, still lacks effective computational design integration. With the improvement of Augmented Reality (AR) technologies (Driscoll et al., 2017) and the appearance of digital platforms, new opportunities to integrate clay manufacturing and computational design have emerged. The concept of digitally transferring crafting skills, using holographic guidance and machine learning, could make clay crafting accessible to more workers while creating the potential to share and exchange digital designs via an open-source manufacturing platform. In this context, this research project explores the potential of integrating computational design and clay crafting using AR. Moreover, it introduces a platform that enables AR guidance and the digital transfer of fabrication skills, allowing even amateur users with no prior making experience to produce complex clay components.

summary Based on the parametric simulation platform and tools, the paper studied the influence of building orientation, building size and window-to-wall ratio on heating and cooling energy consumption of the typical university library in the severe cold region of China. The study established the multiple linear regression models of form design parameters and heating and cooling energy consumption respectively, determined the weight of each parameter, proposed the optimal energy-saving orientation selection and form parameter groups. The energy-saving design strategies of the typical university library in the severe cold region were put forward from the three sub-aspects of building orientation, building size and window-to-wall ratio, and from a comprehensive point of view. The study provides effective support for energy consumption estimation in the stage of building form design, and has important practical significance for sustainable development of university buildings.

summary The increasing urbanization process has led to greater thermal stress on pedestrians, and greenery arrangement can provide an effective mitigation strategy. However, evaluating the environmental impact of different urban morphologies and greenery arrangements using traditional methods requires time-consuming simulations. To address this challenge, we utilized a deep generative model to predict outdoor environmental indicators influenced by greenery and urban morphology. By creating a dataset of Universal Thermal Climate Index, wind speed, temperature, mean radiant temperature, and relative humidity from Envi-met simulations of three building morphologies with randomly distributed greenery arrangements, we found that Building Shadow Exposure (BSE) and Frontal Area Index, as well as BSE and Porosity, had strong interactions. Our study demonstrates that a pix2pix model trained on this dataset can accurately predict the outdoor environment in seconds (R2 > 0.80), making it a promising tool for sustainable urban planning. Thus, our research suggests that deep generative models can accelerate simulation processes and enable more comprehensive studies to support sustainable urban planning in the future.

summary In this paper, we try to investigate architectural site survey process by conducting experiment and quantitative analysis. 17 student volunteers were asked to practice site survey for a fixed design objective. With site survey process recorded along with sketching and utterance, we adopt protocol analysis and FBS ontology, which are widely used and discussed in design process research, as the basis of our analysis. Since site survey is a preliminary stage of architectural design, it differs from actual design process in many aspects. In this case, we extended the original FBS framework by adding two extra activities- Objective Processor and Subjective Processor- to better describe site survey process.

summary This paper shows the content of a subject imparted at the ETSAB (UPC). It describes the use of CAD systems in tasks that could not even be thought before new technology arrival and traditional methods had to be used. CAD systems potential to simultaneously work with constitutive objects and relations between them is taken into advantage. The definite design is not only the juxtaposition of some but the tight relation linking them. This work proposes CAD systems to be used in architectural design projects as spreadsheets to perform arithmetic calculations. The process to obtain an architectural model has ended in a logic sequence of formal operations, which uses completely defined objects as data. Any element of the project, data or operation, can be changed and model updating is automatically performed obtaining the new result. Finally a concrete exercise developed along the course is shown like a practical example.

summary The application of different software, whether simple or complex, can each play a significant role in the design and decision-making on daylighting for a building. This paper, discusses the task to be accomplished, in real case studies, and how various lighting software programs are used to achieve the desired information. The message iterated throughout the paper is one that respects, and even suggests, the use of even the simplest software, that can guide and inform design decisions in daylighting. Daylighting can be complex since the position of the sun varies throughout the day and year as well as do the sky conditions for a particular location. Just because we now have the computing capacity to model every single minute of a day throughout a year, doesn't justify its task. Several projects; an architecture studio, a university office building, a school library and a gymnasium all present different tasks to be achieved. The daylighting problems, the objects and the software application and their outcomes are presented in this paper. Over a decade of projects has led to reflecting upon the importance of computing in daylighting, its staged approach and the result that it can achieve if properly applied.

title VRML History: Storing And Browsing Temporal 3DWorlds
source Proceedings of the fourth symposium on the virtual reality modeling language, ACM Press, pp. 153-160
summary Spatio-temporal data are presented and explored by VR-based visualization systems which offer 3D-navigation and time-navigation for better immersion and analysis. If the visualization results are disseminated on the WWW, they are mostly transformed into videos or, recently, into animated VRML-files which neither support 3D-navigation nor time navigation nor a time-referenced data representation. In this paper, the script language VRML History is proposed which supports the description of spatio-temporal worlds on the internet by conceptually extending VRML with a new time dimension. This is realized by a set of new nodes representing temporal geometries and time references, and a set of Java-classes extending standard VRML-browsers to perform time navigation.

summary Architectural design benefits from a design collaboration between architect and engineers that starts early in the design process. This paper presents a proposal for a new structural language developed to support an early design collaboration between architect and structural engineer. This language expresses the essential characteristics of the conceptual design of the structural engineer, and requires a limited amount of structural engineering knowledge for the architect to comprehend. The language is evaluated in different case studies with architecture and interior architecture students: they show the students' appreciation as it is found easy to learn and use, and a helpful tool in conceptual design collaboration with a structural engineer. Although the language is developed for manual 3D sketching, the paper briefly indicates its potentials for digital 3D representations and more intelligent CAAD like Multi-Agent System (MAS).

summary This work is based on Oliver Grau.s analyses about some aspects of virtual reality. When making his considerations, Grau says virtual reality always has been part of artists. concern when creating their art and, as today, it is an atempt to keep the viewers envolved far from the real world, and deep inside another reality. Oliver Grau.s ponderations are pointed before. Then the comparisons among the installation named .The Place-Rhur., from Jeffrey Shaw, and the panoramas from the XIX and XX centuries are made. It is intended to point out that creations on virtual reality from today are extensions of those that came before. The difference resides on technology employed, cultural context from different moments in which they are created, and the level of envolvment they can offer.

Touching upon different aspects of practice, the presentations highlighted three main directions towards regenerative design: facilitating participatory processes, augmenting creativity by incorporating performance simulations into the early design stages and harnessing digital technologies to manage complex problems. Besides its value as a case study of the Estonian context, the practice panel can serve as an inspiration for a more complex – and messy – understanding of performance.

title Animate Form
source Princeton Architectural Press, New York
summary Animate Form is a book and interactive CD-ROM of recent architectural projects designed by Form, the office of Greg Lynn. The projects documented here explore the potential of time-based animation techniques to inform architectural design. Historically, architecture has been considered static, fixed, and inert. Through the use of state-of-the-art animation and special-effects software, Lynn transforms space and form into highly plastic, flexible, and mutable entities. He uses topological geometries to bend, twist, deform, and differentiate structure, creating unprecedented departures from preconceived notions of architecture. In experimenting with these new methods and media, Lynn has charted an innovative direction in design. The book provides a theoretical context for the experimental projects through a collection of texts by Lynn, extensively illustrated in color. The CD-ROM is an interactive hypertext environment that fully documents the design processes used to generate the projects through animations, renderings, model photographs, videos, and texts. Using a virtual 3D interface, the viewer is able to navigate through space and select objects and animations to view at different scales.

summary This research explores new ways to integrate manufacturing knowledge in to design phases. Through the use of design for manufacturing (DfM) concept, and looking at relations between its potential application in component design and its implementation using digital manufacturing technologies, the author implemented a DfM model that varies from previous models by incorporated learning in the process. This process was based on the incremental development and refinement of design heuristics and metrics. The DfM model developed in this research is a process model to be implemented as a framework within educational settings. The final purpose is to provide better foundational constructs for design education and to improve teaching approaches that integrate design and manufacturing.

summary The design and fabrication of an exhibition display project was taken as an opportunity to explore parametric design with a group of students in Chile. This article presents the experience of a design studio workshop exercise by addressing the introduction of parametric design principles and the development of a built academic project through a team based design and fabrication process. The strategy followed by the team was to utilize parametric models as a mean to materialize driving variables of the project into unexpected geometries to be deployed in different public spaces in Santiago. Context, time scale and available technology resulted in a non-obvious combination of advanced digital design and fabrication techniques and low-cost mass-produced materials.

summary This presentation argues that the concepts of “tools” and “material”, in relation to it use in contemporary architectural design education, can be understood as “instruments” within design processes. The difference between them relies on, its design knowledge abstraction levels, and its mechanisms to capture, manipulate and produce design knowledge. In addition, an initial exploration of Distributed Cognition concept, in order to redefine the use of instruments in design process as Cognitive Instruments, is presented. Furthermore, a more comprehensive framework for design knowledge is presented, including a specific examination of design instruments an its role indesign processes. In the conclusions possible effects derived from the use of “instruments” in design processes are explored.

summary This paper explores new ways to integrate manufacturing processes information in to design phases. Through the analysis of related fields and looking at the relations between its design methods and production processes, we analyze design processes and design representations that already have embedded in them specific ways to materialize through production the artifacts they define. Subsequently, we explore curved surface fabrication using cutting and bending technologies. As a summary, we conceptualize from this top-down development approach to design a framework that integrates design and construction in architecture, based on three possible applications fields: - Design processes improvement - Building production process improvement - CAD-CAM Tools development.

title Autopoiesis and Digital Design Theory: CAD Systems as Cognitive Instruments
source International Journal of Architectural Computing vol. 3 - no. 3, 317-334
summary In contrast to traditional models of design process fundamentally defined by the abstract manipulation of objects, this study recognizes that the resources available for rethinking architecture are to be found in a reformulation of its theory and practice. This reformation should be based on non-linear design processes in which dynamic emergence and invention take the place of a linear design process fixed on a particular object evolution. Advances in computation thinking and technology have stimulated the design and formulation of a large number of design software. Its elaboration supposes a new conceptualization of our discipline's knowledge, in a body of principles and regulations, which commands the artifact's design and its realization; therefore, it constitutes a preliminary datum for its comprehension, and thereby is of theoretical importance. Despite the continuous increment of power in computers and software capacities, the creative space of freedom defined by them acting as cognitive instruments remains almost unexplored. Therefore, we propose a change from a design knowledge based on objects to one focused on design as a network of processes. In addition, this study explores the concept of Distributed Cognition in order to redefine the use of digital tools in design process as Cognitive Instruments.
