title	Kerf Guided Glulam - A novel way of creating curved glulam beams
doi	https://doi.org/10.52842/conf.ecaade.2022.1.085
source	Pak, B, Wurzer, G and Stouffs, R (eds.), Co-creating the Future: Inclusion in and through Design - Proceedings of the 40th Conference on Education and Research in Computer Aided Architectural Design in Europe (eCAADe 2022) - Volume 1, Ghent, 13-16 September 2022, pp. 85–90
summary	This paper proposes a novel way of producing curved glulam timber elements where the formwork is integrated into a glulam beam. The method proposed accomplishes this by placing kerf cuts on a timber profile that gets bent and then encased in a wood laminate, forming the glulam beam. The kerf placement allows the beam to be asymmetrically curved. The optimal placement for the kerf cuts is found by feeding an initial goal curve to a form-finding definition that subdivides it and places markers where cuts need to be made while manipulating the beam geometry, ensuring that it matches the initial input curve. The benefit of this method is that it is not reliant on large-scale glulam setups but can be fabricated with basic wood workshop tools in conjunction with a 5-axis CNC mill. The simplified production process enables smaller manufacturers and designers to produce dynamic wooden structures while saving on materials and labour that would have gone into producing formwork that eventually gets discarded.

title	The Cognition of Residential Convenience Areas Based on Street View Image's Entropy and Complexity - Beijing as an example
doi	https://doi.org/10.52842/conf.ecaade.2021.1.545
source	Stojakovic, V and Tepavcevic, B (eds.), Towards a new, configurable architecture - Proceedings of the 39th eCAADe Conference - Volume 1, University of Novi Sad, Novi Sad, Serbia, 8-10 September 2021, pp. 545-554
summary	This paper quantifies the convenience of living in Beijing by calculating street view image's two inherent properties, entropy and complexity. The image's entropy H can measure the degree of disorder in its pixel arrangement, and the complexity C can measure the "structure" of its pixel arrangement. The study methodology can be divided into four steps as follows. (1) 20,194 Baidu Street View (BSV) images of random geographic coordinates within the study area are crawled as the dataset. (2) Calculate the entropy and complexity of each image separately and plot the entropy-complexity plane. (3) Clustering of data points on the entropy-complexity plane using the K-means algorithm. (4) Analysis of the geographical distribution of the different cluster's data points. The following two conclusions can be drawn from this research. Firstly, low entropy and high complexity street view images can characterize built-up urban areas where the sky occupies a large area, and its buildings are usually more uniform. Conversely, high-entropy and low-complexity images can characterize areas with the more complex built-up environment. Secondly, street view images representing high residential convenience areas in Beijing are characterized by high entropy and low complexity.

title	Associative Spatial Networks in Architectural Design - Artificial Cognition of Space using Neural Networks with Spectral Graph Theory
source	Design Computation Cognition conference 2010
summary	This paper looks at a new way of employing unsupervised neural networks in the design of an architectural system. The method described involves looking the whole lifecycle of a building and its coupling with its environment. Techniques such as dimensionality reduction, it is argued, are well suited to architectural design whereby complex problems are commonplace. An example project is explored - that of an exhibition space where multiple ephemeral exhibitions are housed at any given time. A modified growing neural gas algorithm is employed in order cognize similarities of spaces whose nature are not known a priori. By utilising the machine, a coupling between the building system and the users of the space is explored throughout the whole project life of the design.

title	Biomorpher: Interactive evolution for parametric design
source	International Journal of Architectural Computing vol. 16 - no. 2, 144-163
summary	Combining graph-based parametric design with metaheuristic solvers has to date focused solely on performance-based criteria and solving clearly defined objectives. In this article, we outline a new method for combining a parametric modelling environment with an interactive Cluster-Orientated Genetic Algorithm. In addition to performance criteria, evolutionary design exploration can be guided through choice alone, with user motivation that cannot be easily defined. As well as numeric parameters forming a genotype, the evolution of whole parametric definitions is discussed through the use of genetic programming. Visualisation techniques that enable mixing small populations for interactive evolution with large populations for performance-based optimisation are discussed, with examples from both academia and industry showing a wide range of applications.

title	Evolving Parametric Models using Genetic Programming with Artificial Selection

summary	Evolutionary methods with artificial selection have been shown to be an effective human-computer technique for exploring design spaces with unknown goals. This paper investigates an interactive evolution of visual programs currently used in popular parametric modelling software. Although parametric models provide a useful cognitive artifact for designers to interact with, they are often bound by their topological structure with the designer left to adjusting (or optimising) metric variables as part of a design search. By allowing the topological structure of the graph to be evolved as well as the parameters, artificial selection can be employed to explore a wider design space more suited to the early design stage.

source	IEEE Computer Graphics and Applications. March, 1987. vol. 7: pp. 56-66 : ill. includes bibliography
summary	Many proposals using object-oriented data models for engineering objects have appeared in the literature. These data models try to represent the data in engineering systems more naturally by organizing it logically and/or physically into objects relevant to the engineering applications using the database. The article reviews and examines several of these proposed data models to identify important properties of the models. It shows that none of the data models excels in all areas, but each has desirable properties

summary	Computer media develop progressively day by day. In the process of designing architecture, the employment of digital model seems to become more significant while the traditional physical model have still been used. However, the physical model had some unique characteristics which digital one has not. And those characteristics were what we intended to discover and put into the digital modeling environment developed by us.

title	The Terminal Crit
doi	https://doi.org/10.52842/conf.acadia.1986.079
source	ACADIA Workshop ‘86 Proceedings - Houston (Texas - USA) 24-26 October 1986, pp. 79-87
summary	Numerous attempts have been made to develop formal design methods with -the purpose of increasing the predictability, consistency and dissemination of the design process and improving the quality of the objects produced. The ill- structured nature of design, and the perception of design activities as intuitive and experience dependent have frustrated many of the efforts to structure these process. The growing complexity of the built environment and advances in technology have led to a more rigorous effort to understand and externalize creative activities. Computer aided design tools have recently been playing an important role in the evolution of the design process as a rationally defined activity. The use of- computers for drafting, analysis, and 2 or 3 dimensional modeling is rapidly becoming an accepted method in many design schools and practitioners. A next logical step in the externalization of the design process is to endow the computer with the ability to manipulate and critique parts of the design. Under this scenario, the "terminal crit" is redefined to mean critiques that are carried out by both the designer and the computer. The paper presents the rationalization of the design process as a continuum into which CAD has been introduced. The effects of computers on the design process are studied through a specific incorporation of CAD tools into a conventional design studio, and a research project intended to advance the role of CAD in design.

summary	Family support is the key to the well-being problems of elderly. Unlike health problem, mental is often depended on the social network of elderly. How to enhance elderly well-being problems will become how to increase the interaction between elderly and their family. Horticultural interaction proves to be an effective but smooth impact on improving well-being problems of elderly. With a built-in ambient display and interaction game in mind, a Horticultural Interaction Game (HiGame) is developed, that has connection of both physical and virtual spaces. Elderly through physical watering, weeding, fertilizing to interaction with distant family. And distant family use virtual game of to support elderly.

title	Quantification and Typology Methods for Spatial Regionalism - From Traditional Residence to Modern Chinese-style House Design
doi	https://doi.org/10.52842/conf.caadria.2021.2.081

summary	The cognition of Regionalism in architecture has transferred from the surface to the essence, from the building appearance to space. Modern Chinese-style houses have sprung up all over the country these years but always fail to find back the main characteristic of space in traditional residences. Therefore, the paper focuses on the question of 'what are the main features of the space in traditional Chinese residence', proposing 5 spatial quantification indexes for residential space and a score evaluation method to measure Chinese-style matching degree (Mch) with the help of a modified graph map generation method. 10 traditional Chinese houses and 16 built-up modern Chinese-style houses are taken as samples for empirical research. The paper also puts forward a hypothesis testing model for architects, which can quickly check the Chinese-style matching degree of the scheme and strongly support the design process.

title	A Data-Driven Model for Sustainable Performance Prediction of Residential Block Layout Design Using Graph Neural Network
doi	https://doi.org/10.52842/conf.ecaade.2024.1.575
source	Kontovourkis, O, Phocas, MC and Wurzer, G (eds.), Data-Driven Intelligence - Proceedings of the 42nd Conference on Education and Research in Computer Aided Architectural Design in Europe (eCAADe 2024), Nicosia, 11-13 September 2024, Volume 1, pp. 575–584
summary	Performance evaluation plays a pivotal role in sustainable architectural design, guiding the design direction towards sustainable objectives. Building simulations based on physical modeling are commonly adopted for performance prediction, but the high computational cost hinders their applications in early design stages that require prompt feedback. Surrogate models have been proposed to emulate the expensive high-fidelity building simulation models using data-driven models. Several studies have been conducted to develop surrogate models for sustainable performance prediction of residential block layout design, but the features proposed by these studies were based on specific cases and cannot represent general residential block layout design. To overcome this gap, this study proposes a novel surrogate model for multi-objective sustainable performance prediction based on graph neural network (GNN), which can be adopted in practical early design stages of residential block layout design. First, a graph schema is proposed to represent the general topological relations among components in residential block layout design. Second, an architecture using graph attention network (GAT) is proposed for multiple sustainable performance predictions. Third, a dataset is established based on parametric design models of residential blocks and simulations of sustainable performance, including energy consumption, daylighting, and thermal comfort. Fourth, the proposed surrogate model using the proposed architecture are trained and fine-tuned to learn the relationship between the residential block design and sustainable performance. Finally, the proposed model is evaluated in terms of accuracy, comparing with benchmark models using graph convolutional network (GCN) and artificial neural network (ANN). The results show that the proposed model (GAT) outperforms the benchmark models (GCN and ANN). The proposed model can achieve a satisfactory accuracy with small CV(RMSE)s of 11.97%, 7.88% and 10.11% in terms of energy use intensity (EUI), annual comfort hour (ACH) and useful daylight illuminance (UDI) in the test dataset.

title	Formulating the Generative: History, logic, and status of computing designs in a latent space

summary	This paper separates out and finds relations between individuals and the historical contexts in which they operated who formulated conceptual and computational interpretations of the term generative. It synthesizes literature published from the 1500s to the 1950s, beginning with the Art of Combinations (1500s—) and the pursuit of universal generative languages, leading to the information-processing systems view and heuristic programming (1950s—), the first long-term research program in AI and cognitive science. The present data-driven formulation of the generative enabled by engineering achievements in AI technology has not fundamentally changed a long-standing vision: design or creation as computation remains a kind of mechanized search of design options in a ‘latent space of possibilities.’ Understanding the generative in this way will enable researchers and educators in design, art and science to resolve various controversies that rage today—between cognitivist and connectionist approaches to creativity, between “rules” and “data.”

summary	Learning programming can be a challenging task for design students, especially when code is to be entered in textual form. Visual programming languages, such as McNeil’s Grasshopper, have helped students to engage in scripting without having to deal with lower level syntax that is often hindering them in expressing their thoughts. However, the problem with learning how to program textually is only postponed: When switching to a new platform, students may be forced to learn coding from scratch, and, even worse, to do so in a textual environment that is yet unfamiliar. Our idea is simple: Connect visual programming with textual coding, using code-generation as means. Using this approach enables students to think visually, and see the results textually. An added bonus is the possibility to use debugging, a feature that is yet lacking from Grasshopper. By this way, our language aims to enable students to gradually move from visual to textual programming in a comfortable manner.

summary	During early-stage planning, numerous design decisions are taken in an argumentative manner, based on occupation with the building site according to the different infl uencing aspects (e.g. topology, wind, visibility, circulation, activities etc.). In this context, sketches, diagrams and spreadsheets are the workhorses for elaboration. However, some of these phenomena are dynamic by nature, and are rather poorly modeled when utilizing static media. In our work, we thus show how agent-based simulation can be used to compute and visualize dynamic factors, in order to inform the decision process on a qualitative level. As a matter of fact, simulations may be used as a design tool in their own right, for analysis and objectifi ed comparison among multiple design variations.

summary	Weaving technique is one of the indigenous craftsmanship practices that are common in most of ethnic groups in Indonesia. Generally, it uses thin strips of organic material such as bamboo or rattan to make plane of surface that further can be developed into daily utensils or as a traditional architectural building components such as partition wall and floor. The research of weaving grammar as a system and process had been introduced and explored using Shape Grammar theory and principles. Having the potential implementation and to preserve the traditional weaving method, the grammar can be explored as a method of exploration in architectural design by extending the computation method based on the visual embedding of its pattern languages. The aim of the study is to discover the geometrical configuration underlied traditional weaving grammar by reconfiguring and elaborating procedures and further develop generative method using computational approach. We focused on the exploration of single and dual patterns of biaxial types of West Java woven pattern by using shape grammar principles. The result shows computational method is constructed by several rules which are defined as generative procedure. The result advised that traditional woven pattern has similarity according to its ruled-based system of generative algorithm.

title	Refurb! - A tool allowing for iterative refurbishment

summary	Refurbishments and adaptations to existing building structures can be a challenging problem: Keeping track of all building measures (e.g. what walls, doors and installations to add or remove) is equally demanding as trying to keep an eye on the constraints (e.g. natural lighting) and functions that the changed structure will provide. It also demands a integrated view of the redesign (spatial aspect) and the refurbishment as a project (time aspect). To this end, we have been developing our planning tool "Refurb!", which lets a user plan refurbishments and adaptations to existing structures using a mixed metaphor of "CAD-tool + project plan", including a variety of analysis tools to compare the original state of a structure to the planned one (e.g. adjacency and circulation before and after adaptation). The tool is aimed at project planners and ranges from small scenarios (e.g. relocation/adaptation/refurbishment of a department) to big scenarios (e.g. relocation when bringing a hospital into service).
