title	Redefinition of Heritage Public Spaces Using PPGIS: The Case of Religious Complex in Old Cairo
source	Abdelmohsen, S, El-Khouly, T, Mallasi, Z and Bennadji, A (eds.), Architecture in the Age of Disruptive Technologies: Transformations and Challenges [9th ASCAAD Conference Proceedings ISBN 978-1-907349-20-1] Cairo (Egypt) [Virtual Conference] 2-4 March 2021, pp. 355-370
summary	Plenty of challenges all over the world are affecting the urban development of spaces in the cities, especially those of heritage sites; these urban spaces provide various ambiances that appeal to the senses. Although surrounded open spaces in heritage sites are full of rich, deep knowledge that plays an active role in the community perceptions, it has been recently neglected. A contribution is paid to the combination of digital technologies to help in preserving those spaces. Its integrated use could exponentially increase the effectiveness of conservation strategies of ancient buildings. GIS technology became a usual documentation tool for heritage managers, conservators, restorers, architects, archaeologists, painters, and all other categories of experts involved in cultural heritage activities. Consequently, the GIS has faced strong criticism as it is a tool for documentation without engaging in the public environment and the users’ needs; as a result, GIS cannot help in any enhancing process as it does not have any idea about the needs of the users. This paper analyses public uses efficiency in heritage public spaces in Cairene context using public participation geographic information system (PPGIS) methodology, as it gives attention to the term “user” to include the “public” incorporating the concept of “public participation” commonly used in planning. An online survey was set up, based on Google Maps, where respondents were asked to place and rate twenty-five items on an interactive map done by (ARCGIS 10.4). These items were based on the criteria of placemaking to make those spaces full of creative ambiance to be more attractive and useful to the communities. Finally, 200 valid surveys have been collected and mapped 1500 opinions have been mapped. The Results of this research show that PPGIS is an effective tool in measuring the efficiency of those heritage public spaces, which may be valuable for future planning.

summary	Due to the more significant architectural complexity, it is helpful to include structural analysis studies in the early design stages. An architectural team typically carries out the structural grid fit in this phase. This limitation may lead to the structural distribution in the initial phase not being the most appropriate. This work aims to provide a tool for architects oriented design by optimising the cost of the structure, making an initial layout for residential buildings with the regular shape of steel structures using the generative design, which allows the creation of structural BIM models that comply with the requirements of stability and resistance for gravity design specified in the American code ASCE 360 as starting point on the conceptual design. The paper describes the computational design development for the structural building grid using multi-criteria optimisation solved by a genetic algorithm.

summary	Recent advancements in robotics allow to explore remote construction methods aimed at reducing the risk for workers. As the global pandemic places construction workers and their communities at high risk for disease, the need for remote construction methods increases. Such methods depend on the complicated task of controlling mobile robotic platforms in real-time. In this context, this paper presents work-in-progress in development and experimentation with a tool for collaborative earthworks using multi-agent unmanned ground vehicles. Expanding the field of collective robotic construction, this research simplifies the use of mobile robots and enables their operation using a design platform. Shepherd - a fabrication-oriented tool for simulation and control of mobile robotic platforms is presented, and its capacities are demonstrated in an earthworks case study. The case study exemplifies the potential of this approach to change the role of design tools in the operation and adoption of mobile multi-robotic platforms, thus contributing to robotic fabrication in architecture, landscape architecture, and construction.

summary	This contribution introduces a methodology for early planning phases, which is based on a stakeholder oriented analysis of process-related user functions and supports the elaboration of a structural and formal building concept. Also a so-called FunctionsTool is presented, that supports the user oriented development, structuring and grouping of user functions and leeds to a qualified allocation of the functions and their spatial-temporal interdependencies. This tool and also other existing methodical and digital approaches have been evaluated for the complex application-context of hospital planning. So, on a methodological level, a further concept could be drawn up as well as recommendations for the further development of the digital FunctionsTool.

title	Spaces Identity Evaluation aNd Assignment - SIENA - A duck typing approach for automatic recognition and semantic enrichment of architectural spaces
source	Stojakovic, V and Tepavcevic, B (eds.), Towards a new, configurable architecture - Proceedings of the 39th eCAADe Conference - Volume 2, University of Novi Sad, Novi Sad, Serbia, 8-10 September 2021, pp. 341-350
doi	https://doi.org/10.52842/conf.ecaade.2021.2.341
summary	This paper presents the development of SIENA - Space Identity Evaluation aNd Assignment - based on duck typing for automatic recognition and semantic enrichment of the architectural spaces. This method is known in computer science as a form of abductive reasoning and leverages on the observable features of an object in order to establish its recognition. As result, the spatial identity is object-oriented and can be dynamically defined. In this research, the duck typing approach has been achieved with the support of BIM methodology and graph database. The former allows information-based modeling of an architectural project while the latter makes possible the representation of the knowledge along with their relationships. Consequently, this research may have many possible applications, especially as a valid design support tool in the very first design stages. Furthermore, an efficient spatial identity detection could contribute to the development of further human-machine interactions and therefore a possible optimization of the design process.

title	Territories Made by Measure: The Parametric as a Way of Teaching Urban Design Theory
source	Abdelmohsen, S, El-Khouly, T, Mallasi, Z and Bennadji, A (eds.), Architecture in the Age of Disruptive Technologies: Transformations and Challenges [9th ASCAAD Conference Proceedings ISBN 978-1-907349-20-1] Cairo (Egypt) [Virtual Conference] 2-4 March 2021, pp. 494-506
summary	Design tools like Grasshopper are often used to either generate novel forms, to automate certain design processes or to incorporate scientific factors. However, any Grasshopper definition has certain assumptions about design and space built into it from its earliest genesis, when the initial algorithm is set out. Correspondingly, implicit theoretical positions are built into definitions, and therefore its results. Approaching parametric design as a question of architectural, landscape architectural or urban design theory allows the breaking down of traditional boundaries between the technical and the historical or theoretical, and the way parametric design, and urban design history & theory, can be conveyed in the teaching environment. Once the boundaries between software and history & theory are transgressed, Grasshopper can be a way of testing the principles embedded in historical designs and thus these two disciplines can be joined. In urban design, there is an inherent clash between an ideal model and existing urban geography or morphology, and also between formal (qualitative) and numerical (quantitative) aspects. If a model provides a necessary vision for future development, an existing topography then results from the continuous human and natural modifications of a territory. To explore this hypothesis, the “Urban Design Representation” subject in the Master of Urban Design program at the University of Cape Town taught in 2017 & 2018 was approached “parametrically” from these two opposite, albeit convergent, starting points: the conceptual/rational versus the physical/empiric representations of a territory. In this framework, Grasshopper was used to represent typical standards and parameters of modern urban planning (for example, Floor/Area Ratio, height and distance between buildings, site coverage, etc), and a typological approach was adopted to study and “decode” the relationship between public and private space, between the street, the block and topography, between solids and voids. This methodology permits a cross-comparison of different urban design models and the immediate evaluation of their formal outputs derived from parametric data.

title	A Distributed Agents Approach for Design and Fabricating Process Management among Prototyping Practice Environment

doi	https://doi.org/10.52842/conf.caadria.2021.1.593
summary	This paper develops a design and fabrication process management platform for prototyping practice environments using a robot operating system (ROS) framework, which we refer to as a fabricating operating service (FOS). The FOS executes a sequence of fabrication workflow that goes from materials handling, positioning, fabrication simulation, executing process to parts assembling. Each work phase is considered a different activity in the execution phase and a compact printed circuit board node to send and receive physical data. These nodes are registered onto an FOS cloud master, which distributes the node-to-node communication and links up the entire sequence of the workflow map. We propose FOS given that its loose, coupled, and distributed computation framework allows the fabrication team to visualize and record data using sharable ROS package structures. The FOS provides the advantage of easily creating additional tools, configurations, and automated scripts, and it increases the fabrication capabilities by simplifying and providing solutions for future robotic-aided fabrication development.

doi	https://doi.org/10.52842/conf.caadria.2021.2.549
summary	With the use of the concept Central Activities Zone in the Shanghai City Master Plan (2017-2035) to replace the traditional concept of Central Business District, core areas such as Shanghai Lujiazui will be given more connotations in the future construction and development. In the context of todays continuous urbanization and high-speed capital flow, how to identify the development status and vitality characteristics is a prerequisite for creating a high-quality Central Activities Zone. Taking Shanghai Lujiazui sub-district etc. as an example, the vitality value of weekday and weekend as well as 19 indexes including density of functional facilities and building morphology is quantified by obtaining multi-source big data. Meanwhile, the correlation between various indexes and the vitality characteristics of the Central Activities Zone are tried to summarize in this paper. Finally, a neural network regression model is built to bridge the design scheme and vitality values to realize the prediction of the vitality of the Central Activities Zone. The data analysis method proposed in this paper is versatile and efficient, and can be well integrated into the urban big data platform and the City Information Modeling, and provides reliable reference suggestions for the real-time evaluation of future urban construction.

summary	Clay is one of the foundational materials in art and architecture, traced in the development of mud walls and the adobe module, and showcased in utilitarian and ornamental pottery. Wheel throwing is the process of shaping clay mainly into symmetrical objects, a complex craft in which the master potter has the knowledge and skill to manipulate the clay into the final design of various physical objects. This project explores how Machine Learning can be used to translate the richness and complexity of wheel throwing for digital fabrication. In this paper we present a surrogate digital dataset for robotic fabrication and geometric prediction used to train neural networks and provide a bridge between digital fabrication and handcraft. We report on the parametric model which abstracts wheel throwing as the interaction between a rotating mass and a given set of forces, as well as on data wrangling methods, dataset composition considerations, and training methodology. We present two models, one in which geometry is predicted based on a given set of forces, and a second in which forces are predicted based on a given geometry. Lastly, we give a critical assessment of the predictions of both networks and discuss future steps.

summary	The article aims to demonstrate the applicability of the use of programming in the formation of floor plans in the initial design of the architectural layouts of houses of social interest and to evaluate the possible cost of building these proposals. The development of the algorithm follows known programming rules and structures written in a visual modeling and programming software, in addition to using the methods of stochastic search, shape grammar, CUG (geometric unit cost) and CUB (basic unit cost). As a result, it was possible to develop space layouts that resemble the rooms of a single-family home and calculate their possible construction cost. The use of the complete process also brings the discussion of the use of technologies and automated processes within current design practices, demonstrating how the use of these technologies can enhance the imagination and present compositions and quantitative results not envisioned by the designers.

title	Eelish 2.0: Grasshopper Plugin for Automated Grid-Driven Column-Beam Placement on Orthogonal Floor Plans - Formalising manual workflow into an algorithm through empirical analysis
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. 427-436

summary	The implicitly parametric if-else logic of determining column-beam locations is applied manually on virtually every orthogonal design, thereby inflating workhours and cost through unnecessary repetition of labour. This paper presents the development of a generative algorithm (developed as Grasshopper plugin Eelish 2.0) that automates the placement of column centre points and beam centre lines on orthogonal floor plans. The manual process of column-beam placement is formalised as the algorithm through empirical analysis of layouts drawn by architects. The placement is executed iteratively from the largest room to the smallest room. It is guided by local and/or global orthogonal grids that are generated using walls of other rooms and beams of rooms calculated till the previous iteration. The placements are controlled by the maximum and minimum allowed spans of slabs, and four modes of grid generations. The generated layouts have a qualitative 'Satisfactory' or better approval rating of 82.4% by architects and 88.4% by structural engineers.

summary	The implicitly parametric if-else logic of determining column-beam locations is applied manually on virtually every orthogonal design, thereby inflating workhours and cost through unnecessary repetition of labour. This paper presents the development of a generative algorithm (released as Grasshopper plugin Eelish) which automates the placement of column centre points and beam centre lines on orthogonal floor plans with the aim of maximising regular ceiling division. The manual process of column-beam placement is formalised as the algorithm through empirical analysis of layouts drawn by architects. Regular ceiling division is maximised in a concave room by calculating column-beam grid of the largest rectangle inscribable in the room, and then extending the grid to the entire room. The placements are guided by the maximum and minimum allowed spans of slabs, and the maximum allowed span of cantilever slabs. The generated layouts have a qualitative ‘Satisfactory’ or better approval rating of 93.5% by architects and 83.6% by structural engineers.

summary	Although HBIM is nowadays a common practice in processes and activities aimed at the investigation, documentation and conservation of architectural heritage, some doubts are emerging regarding its capabilities of fulfilling architectural heritage representation and semantics requirements. In this context, this work presents Open-ArcH, a digital approach for architectural heritage representation that relies on the integration of HBIM methodology with a knowledge base developed by means of graph databases, with two major objectives: 1) it supports the formalization of the complex semantics that it is necessary for a full comprehension of the artefact, currently poorly managed by HBIM application, and 2) the openness and flexibility ensured by the graph database technology allow for its adoption in heritage investigation and conservation processes by the different actors involved, providing them with the capability of collaborating to the construction of the knowledge base of the artefact.

summary	Cultural heritage conservation has two aspects, tangible and intangible, both of which contribute greatly to the understanding of ancient inheritances. Due to the role of education in the preservation process, and the strength of the new media in the current era, serious games can play a key role in conservancy by transmitting the target culture. There is a gap in the serious game field in relation to Turkey's cultural heritage on the Silk Roads, underlining the motivation of this research. Hence, this study proposes the Anatolian Journey serious game, which is developed in the Twine platform, designed to transmit Turkey's tangible and intangible cultural heritage, providing comprehensive information on the Seljuk caravanserais, located on the Silk Roads. Moreover, the research compares undergraduate and graduate students' gains in knowledge of heritage data while playing a serious game and encountering the same content in text form with an online survey.

summary	Most approaches developed to teach parametric design principles in architectural education have focused on universal strategies that often result in the fixation of students towards perceiving parametric design as standard blindly followed scripts and procedures, thus defying the purpose of the bottom-up framework of form finding. Material-based computation has been recently introduced in computational design, where parameters and rules related to material properties are integrated into algorithmic thinking. In this paper, we discuss the process and outcomes of a computational design course focused on the interplay between the physical and the digital. Two phases of physical/digital exploration are discussed: (1) physical exploration with different materials and fabrication techniques to arrive at the design logic of a prototype panel module, and (2) deducing and developing an understanding of rules and parameters, based on the interplay of materials, and deriving strategies for pattern propagation of the panel on a façade composition using variation and complexity. The process and outcomes confirmed the initial hypothesis, where the more explicit the material exploration and identification of physical rules and relationships, the more nuanced the parametrically driven process, where students expressed a clear goal oriented generative logic, in addition to utilizing parametric design to inform form finding as a bottom-up approach.

title	The Use of Diagrammatic Reasoning to Aid Conceptual Design in Building Information Modeling (BIM)
source	Stojakovic, V and Tepavcevic, B (eds.), Towards a new, configurable architecture - Proceedings of the 39th eCAADe Conference - Volume 2, University of Novi Sad, Novi Sad, Serbia, 8-10 September 2021, pp. 39-48
doi	https://doi.org/10.52842/conf.ecaade.2021.2.039
summary	Architectural design is an intellectual activity where the architect moves from the abstract to the real. In this process, the abstract represents the logical reasoning of how architectural form is configured or structured, while the real refers to the final physical form. Diagrams become an integral part of the conceptual design stage because they mediate between those two realms. Building Information Modeling (BIM) can reallocate the effort and time to emphasize conceptual design. However, many consider BIM a professionally-oriented tool that is less suitable for the early design stages. This research suggests that architectural design reasoning can be achieved using constraint-based parametric diagrams to aid conceptual design in BIM. The study examines several techniques and constructs a framework to use diagrams in the early design stages. This framework has been investigated through Villa Stein and Citrohan House by Le Corbusier. This study addresses two roles of diagrams: the generative role to create various design solutions and the analytical one to conduct an early performance study of the building. Our research contributes to the discussion on the ways designers can use digital diagrams to support the architectural design process.

title	The Assembly and Fabrication of Double Curved Panel Structure Using Japanese wood Joints created by Desktop 3D Printers
source	Gomez, P and Braida, F (eds.), Designing Possibilities - Proceedings of the XXV International Conference of the Ibero-American Society of Digital Graphics (SIGraDi 2021), Online, 8 - 12 November 2021, pp. 1245–1255
summary	This research presents a new direction for freeform structure assembly and fabrication through the collaboration of 3D printing technology and Japanese wood joining technology. Full-scale, self-build prototyping is demonstrated without glue or metal fittings. Rather than relying on digital fabrication machines to match the architectural scale, this study utilizes the Fused Filament Fabrication (FFF) with desktop 3D printers, which is the most widespread and inexpensive printing technology. By incorporating the perspectives of wood joinery and compact 3D printers, this study promotes a drastic change in 3D printed architectural production from a massive structure-oriented system to a module-oriented system. The project demonstrates how artisanal knowledge integrates with 3D printing architectural production by reconfiguring joint geometry, parametric modeling, fabrication, and assembly processes.

summary	The use of evolutionary methods in design and art is increasing in diversity and popularity. Approaches to using these methods for creative production typically focus either on optimisation or exploration. In this paper we introduce an evolutionary system for design that combines these two approaches, enabling users to explore landscapes of design alternatives using design-oriented measures of fitness, along with their own aesthetic preferences. We test our methods using a biologically-inspired generative system capable of producing 3D objects that can be exported directly as 3D printing toolpath instructions. For the search stage of our system we combine the use of the CMA-ES algorithm for optimisation and linear interpolation between generated objects for feature exploration. We investigate the systems capabilities by evolving highly fit artefacts and then combining them with aesthetically interesting ones.

title	A Shape Grammar Implementation: The Case of Fishing Villages in Santa Catarina

summary	The fishing villages of the Santa Catarina state, in Southern Brazil, have been suffering from a process of transformation that accompanies the replacement of the activities related to artisanal fishing in order to insert the dynamics of tourism. Aiming to preserve the underlying logic responsible for generating these self-built settlements, a shape grammar was elaborated and implemented in a visual programming environment to test its efficiency in reproducing the compositional language of the villages. The method involved the historical context and constructive typologies analysis, which made it possible to extract the corresponding rules regarding the spatial configuration of the corpus. The result emerged as a descriptive grammar, which later was implemented in a parametric modeling environment, algorithms in C# were used to generate the compositions with the aid of computational strategies based on random numbers, stochastic research and object-oriented programming.
