title	Synthetic Digital Ecologies

summary	Why use the terms synthetic and ecology in the context of a conference dedicated to the field of digital architecture, computation and fabrication? How do we begin to unpack the synthetic union of diverse elements, processes, collaborators, and code underlying any single contemporary design or research project? What could our field gain by interrogating these diverse ecologies? What are the relationships and interactions between our design processes, including our various tools and techniques, and the multiple environments with which we routinely work, collaborate and make? It is these questions and more that we hope to address at this year’s “Synthetic Digital Ecologies” conference. A quick scan of the papers and projects that will be presented at ACADIA reveals an extraordinary ecology of experimental research that emerged by working between messy labs, studios, workshops, hacker spaces and the like. In many ways today’s so-called “digital architects” do not feel compelled to distinguish between what is digitally designed and what is not. They are leading the way through a promiscuous and synthetic mixing of skill sets, of pens and paper, hardware and software, electronics and g-code. In a single research project these designers might collaborate with a computer scientist, a robotics expert and a glass blower, and in many cases they might even attempt to do all of these things themselves. It was with this in mind that we put forth an international call inviting, “… architects, fabricators, engineers, media artists, technologists, software developers, hackers and others in related fields of inquiry …” to submit papers and projects for this year’s conference. This year the proceedings have been organized into twelve synthetic categories based around the potential for diverse research topics to inform new and unexpected conversations. Instead of organizing peer-reviewed papers and projects through their formal characteristics, we were interested in forming new synthetic categories by curating unexpected juxtapositions. This ecology of ideas and research was meant to provoke and inspire new ways of thinking, making, building and collaborating.

summary	It is an immutable truth that architecture ultimately exists for humans. Similarly, it is a well-known fact that countless architectural concepts derived and evolved to restrain development, to control building projects and to consider environment are eventually for the benefit of humans. Architecture today, however, is in the hands of a few renowned architects even though it is supposed to refl ect human beings and times and to work for everyone. Is it too much to say that everyone should have a say in the space used by many? In that respect, we have devised DADL System. Anyone, Anytime, Anywhere. The system is an architectural game that stimulates human instincts, has online communities and is easily accessible by Anyone Anytime and Anywhere (3A Rules). DADL System aims to gather users’ ideas and develop architecture, which is essentially enabled by the ‘Advise’ feature. Advise is designed to lead users to think about architecture voluntarily and to guide them to express their ideas. The structure and contents of Advises are very important factors in DADL System. Also, it is divided into two domains, i.e. Web and Mobile, where data exchange is enabled via cloud computing, establishing a base in compliance with the ‘3A’ Rules. The DADL System supports the architecture of everyone without relying on opinions of a few, so as to open the infi nitive potential for communication between architecture and humans, which today’s architecture should advocate.

title	Information Technology Utilization in Architectural Engineering: A Field Investigation at the Department of Architecture and Construction, Constantine (Algeria)
source	CAAD \| INNOVATION \| PRACTICE [6th International Conference Proceedings of the Arab Society for Computer Aided Architectural Design (ASCAAD 2012 / ISBN 978-99958-2-063-3], Manama (Kingdom of Bahrain), 21-23 February 2012, pp. 155-156; 273-284
summary	This paper is derived from an under developed research work, that is a PhD thesis which studies the influence of Information Technology (IT) on architectural practice in Algeria. It examines the use of IT by students of the Department of Architecture and Construction in Constantine in their design studio’s projects. The target of the study is to inspect the depth of utilization of IT, identify the advantages and shortcomings of use, and propose some solutions. A field survey was undertaken on a sample of students at the Department of Architecture and Construction. The survey has the following objectives: • to find out the students’ motivation behind the adoption and use of IT in their projects; • to identify the negative and positive aspects of use; • to identify the barriers that would hinder better use; and • to determine the impact of the IT tools on the design process and projects. // For a more comprehensive comprehension of the study case; a pilot field survey was conducted during two consecutive years. This enables the researchers to make comparisons between the survey’s results of the same year, and to study the trends of use by making comparisons between the results of these two years. SPSS was used to analyze the results. The analysis of results shows that the IT helps largely to improve the quality of presentations of the documents, images and graphics but this was an attempt from students to satisfy and influence the "others". In some cases, this has negatively affected the quality of design projects. It was used by students with poor design skills to cover up some weak aspects and faults in their design projects. On the other hand, some tutors opposed the exaggerated use of IT and the complete dependence on the computer during the design stage. They prefer the "traditional way" of design development. There is an ongoing conflict and arguments between students and tutors regarding this matter. However, It was noticed that the IT has effectively contribute in improving the competition level between students thus the quality of their design projects.

title	Online conversational strategies in technical advisory meta-learning for socio-spatial groups.
source	Herrera, PC, Dreifuss-Serrano, C, Gómez, P, Arris-Calderon, LF, Critical Appropriations - Proceedings of the XXVI Conference of the Iberoamerican Society of Digital Graphics (SIGraDi 2022), Universidad Peruana de Ciencias Aplicadas, Lima, 7-11 November 2022 , pp. 1063–1074
summary	The article makes a critical reflection on a remote learning experience for training specialists in Spatial Agency for Social Housing - ATHIS. The objective was to promote conditions for students to problematize about 'how' digital technologies could be appropriated in ATHIS. A meta-learning process was envisioned with the objective of experiencing in practice a co-creative dynamic using digital tools. Based on radical constructivist thinking, the proposed methodology used the digital platforms Zoom and Miro to associate two cybernetic collaborative ideation strategies: Team Syntegrity (Beer, 1994), and GIGAmapping (Sevaldson, 2012). The results showed that the experience significantly contributed to the expansion of knowledge of each participant regarding the topics studied and allowed the reverberation of individual contributions throughout the team. Once it has been verified that collaboration interfaces enable but do not guarantee collaborative work, we bring to the discussion three other structuring components that can be allies of simultaneous and integrated online work between groups.

title	INTELLIGENT KNOWLEDGE-BASED REPOSITORY TO SUPPORT INFORMED DESIGN DECISION MAKING
source	ITCON journal
summary	Research highlights that architectural design is a social phenomenon that is underpinned by critical analysis of design precedents and the social interaction between designers including negotiation, collaboration and communication. CAAD systems are continuously developing as essential design tools in formulating and developing ideas. Researchers such as (Rosenman, Gero and Oxman 1992) have suggested suggest that knowledge based systems can be integrated with CAAD systems to provide design knowledge that would enable recalling design precedents that maybe linked to the design constraints. Currently CAAD systems are user centric being focused on architects rather than the end product. The systems provide limited assistance in the production of innovative design. Furthermore, the attention of the designers of knowledge based systems is providing a repository rather than a system that is capable to initiate innovation. Most of the CAAD systems have web communication tools that enable designers to communicate their design ideas with colleagues and partners in business. However, none of these systems have the capability to capture useful knowledge from the design negotiations. Students of the third to fifth year at College of Architecture, University of Dammam were surveyed and interviewed to find out how far design tools, communications and resources would impact the production of innovative design projects. The survey results show that knowledge extracted from design negotiations would impact the innovative design outcome. It highlights also that present design precedents are not very helpful and design negotiations between students, tutors and other students are not documented thus fully incorporated into the design scheme. The paper argues that the future CAAD systems should be capable to recognize innovative design precedents, and incorporate knowledge that is resulted from design negotiations. This would help students to gain a critical mass of knowledge that would underpin informed design decisions.

summary	Design is a social phenomenon and the previous research highlights that design precedents and social interaction between designers including negotiation, collaboration and communications is essential to initiate creativity and the production of innovative design products. CAAD systems aim is to help the architect in formulating and developing design ideas. Researchers suggest that knowledge based systems can be integrated with CAAD systems so it would provide the architect with design knowledge that would him/ her to recall design precedents/ solutions thus link it to the design problems. Nevertheless, CAAD systems can provide limited help regarding the production of innovative design. Furthermore, the attention of the designers of knowledge based systems is focused on architects rather than the end product. On the other hand, most of the CAAD systems have web communication tools that enable designers to communicate their with colleagues and partners in business.

summary	GENE_ARCH is a Generative Design System that combines Pareto Genetic Algorithms with an advanced building energy simulation engine. This work explores its integration with a Shape Grammar, acting as GENE_ARCH’s shape generation module. The urban patio house typology is readdressed in a contemporary context, both by improving its energy-effi ciency standards, and by rethinking its role in the genesis of high-density urban areas, while respecting its specifi c spatial organization and cultural grounding. Field work was carried out in Marrakesh, surveying a number of patio houses which became the Corpus of Design, from where a Shape Grammar was extracted. The computational implementation of the patio house grammar was done within GENE_ARCH. The resulting program was able to generate new, alternative patio houses designs that were more energy effi cient, while respecting the traditional rules captured from the analysis of existing houses. After the computational system was fully implemented, it was possible to complete different sets of experiments. The first experiments kept more restrained rules, thus generating new designs that closer resembled the existing ones. The progressive relaxation of rules and constraints allowed for a larger number of variations to emerge. Analysis of energy results provide insight into the main patterns resulting from the evolutionary search processes, namely in terms of form factors of generated solutions, and urban densities achieved.

summary	Current trends in architectural practice such as an increased focus on sustainable design, integrated design, and the globalization of architecture are increasing the need for practitioners that are skilled in collaboration. Collaboration fosters innovation and creativity. It is a key operating principle for the 21st century and an important skill that an architecture student must be exposed to. The change in knowledge generation and creative problem solving is transforming education towards collaborative learning forcing architecture and engineering schools to address new course structures with “collaborative” aspect. The work presented in this paper draws its base from collaborative design learning. It describes an international collaborative design studio titled “International Design Studio: Green Transformable Buildings” conducted between three institutions, Y_ld_z Technical University (YTU)–Istanbul, University of Twente (TU)-Enschede Engineering Sciences and Industrial Design School, and Architecture Faculty of Sarajevo (AFS).

title	Some advice for migrating to IFC
source	Proceedings of the 17th International Conference on Computer Aided Architectural Design Research in Asia / Chennai 25-28 April 2012, pp. 265–274
doi	https://doi.org/10.52842/conf.caadria.2012.265
summary	Nowadays, the BIM (Building Information Modelling) paradigm is a central topic in the CAAD community. Next to the commercial solutions, the IFC (Industry Foundation Classes) have emerged as the best open standard candidate for BIM interoperability. Despite the efforts of the community for promoting IFC over the last 15 years, it seems that its practical adoption in real-life projects has been very limited. The goal of this article is to explore how useful IFC can be today and to provide the reader with some advice for an effective adoption of IFC. Over the last year, we have conducted a project aiming at acquiring a sound understanding of IFC. It was made of two complementary investigations. On one hand, we have focused on the commercial modelling tools and the IFC support they were offering. On the other hand, we have focused on the IFC-based software developments. We have developed a tool converting IFC files into a dedicated thermal assessment based model. We will summarise the experience we have acquired in this project into some advice for users migrating to IFC. Our goal is to confront the practical aspects of the IFC developments, with both the theoretical ambitions and the commercial support currently available.

title	Architecture, Digital Techniques & Project Management

summary	With the invention of computers, Architecture and other Engineering disciplines have undergone revolutionary developments offering new opportunities for improving efficiency and opening new frontiers for creativity. For example in architecture and urban planning, the discussions have been extended from conventional writings to cover cyberspace, virtual architecture and digital city. Moreover, computers have helped in the realization of many complex projects that would be inconceivable with traditional drawing techniques. This is clearly demonstrated in the works of Frank Gehry's, Zaha Hadid, Daniel Libeskind and many others. In deed, digital techniques have changed the design creative process and how the architects think. Traditionally the structured development architectural ideas from 2D drawings (plans, sections, elevations) towards 3D resolution has been replaced by more interactive approach of 2D & 3D. The changes that digital techniques have brought to the field of Architecture; including practice and education, can obviously be viewed from different angles and incite many discussions and questions. However, the purpose of this presentation is to discuss the role of digital techniques within the overall framework of project management in Gulf Housing Engineering. It starts the discussion with a brief on architecture and digital techniques in the Gulf Region, especially during the “boom period”; a period characterized by rapid production of buildings relying heavily on virtual images. It is against this background, the role of digital techniques is evaluated from a practice point of view. In fact in GHE, digital means are integral parts of the holistic project delivery process starting form initiation, to various design stages to construction ending with project completion. In this process emphasis is paid to the inter-relationships between IT Systems and Quality Control which in turn facilitate measuring, monitoring and reporting on various managerial, technical and design and budgetary aspects of the project. The presentation is supported by real case studies of GHE portfolio. It emphasizes that digital techniques should be an integral part of an overall process and should be seen as means to enhance efficiency and creativity; and should contribute to the betterment of the built environment

title	Las redes sociales como apoyo a la realización del proyecto arquitectónico en el ámbito universitario [Social network to support the development of the architecture project in the university]
source	SIGraDi 2012 [Proceedings of the 16th Iberoamerican Congress of Digital Graphics] Brasil - Fortaleza 13-16 November 2012, pp. 104-108
summary	Nowadays, the subject of social networking is closely related to leisure, publicity and marketing. Few people consider them as a tool to support learning. However, with their daily activities online, students are developing, without thinking, skills that we do not directly perceive, such as collaborative work, interest and motivation for research. With the adequate methodology and teacher support, it is possible to guide these skills, innate in students, and get an effective collaborative work in developing the project. Through this research, applied to students of architecture, schemes are proposed to improve the teaching-learning process, and extend beyond the classroom.

summary	Building Information Modeling (BIM) has been considered as an emerging collaborative strategy since its introduction, meant for AEC industry and heading to benefits in terms of costs and design quality during the whole building lifecycle. BIM approach, originally developed for new projects, can be successfully applied to existing contexts using TLS surveys to collect point clouds and turn them later into smart digital models, taking advantage of new technologies and methods. This paper addresses these themes paying attention to issues and opportunities, considering BIM as a paramount tool to collect and manage data destined to multiple disciplines

summary	This article is a starting point for the development of experiential urban co-design interfaces to enhance public participation in local urban projects and to be also used as a communication and collaboration tool in urban design. It is based on the previous research involving 3D city models utilized as understandable design interfaces for the non-technical public (Jutraz, Zupancic, 2011), where we have already explored different views (pedestrian, intermediate and bird’s-eye view), as well as the means by which the information obtained from these different views may be combined by shifting between viewpoints. Previous work was conducted in the “street lab” as well as the Urban Experimental Lab, which was developed specifi cally for the public’s participation in urban planning (Voigt, Kieferle, Wössner, 2009). Presented in this article is the next step that explores the immersive collaboration environment 3D ICC [1], formerly known as Teleplace. The environment was developed for effi cient collaboration and remote communication and shifts the research focus towards questions regarding how to employ both labs as interfaces between the non-technical public and design professionals. As we are facing the lack of digital systems for public participation and education in urban design, different digital tools for communication and collaboration should be combined into a new holistic platform for design. A digital system of tools needs to be developed that supports the urban design decision-making process and focuses on improved final solutions and increased satisfaction amongst all participants. In this article the system of digital tools for public participation, which include communication, collaboration and education, will be also defi ned, with its basic characteristics and its elements.

title	A responsive morphing media skin
source	Proceedings of the 17th International Conference on Computer Aided Architectural Design Research in Asia / Chennai 25-28 April 2012, pp. 517–526
doi	https://doi.org/10.52842/conf.caadria.2012.517
summary	Existing media façades do not function as fenestration devices. They have been used mainly for visual communication and aesthetic purposes. This paper introduces a responsive morphing skin that can act as an active fenestration device as well as a media skin. We investigate new possibilities of using form-changing materials in designing responsive morphing skins that respond to environmental conditions and act as a communicative display. The design experiment that embodied this investigation, namely Blind, serves as a new layer of analogue media brise-soleil for existing space. It communicates the relationships between interior and exterior spaces visually and projects mutable imageries to the surrounding environment through sunlight. The design process of Blind simulates the responsive behaviour of the intended architectural skin by integrating physical computing and parametric design tools. This process includes the integration of soft apertures and architectural morphing skin to introduce a novel design method that enables an architectural skin to be a means of communication and fenestration.

title	CAD e BIM: Transições e reflexos no ateliê de projeto [CAD and BIM: Transitions and reflections on the architectural design studio]

summary	The purpose of this paper is to analyse, through a case study, the teaching-learning practices in the design studio, establishing a parallel between the use of CAD (Computer-Aided Design) and BIM (Buiding Information Modelling) tools. It aims to comprehend how this transition unfolds and to identify their reflections on the graphical representation of architectural projects, based on the results of students’ works and on the interview realized. The results confirm the transition context, by concomitant use of both softwares by many students, and bring into question the maintenance of products generated by new designing processes.

summary	During a design process, few methods allow designers to evaluate if and how the future building will match and affect its intended use and its intended users. Computer simulation techniques have focused on prediction of human behavior in built environments in order to overcome this lack; nevertheless, their applications are limited to representation of specifi c behavioral aspects while a reliable representation of building response to actual use is still missing. Based on current developments in the video game industry, the research described here aims to establish a new approach to simulating human behavior in buildings, centered on a clear definition of use scenarios as specific structures of active entities called Events. They provide information about occurrences happening during the use process in terms of Actors involved, Activities performed and Space where the event takes place. Equipped with AI engines, events control and coordinate the actors’ behavior during the simulation, representing their interaction, cooperation and collaboration.

title	Point Cloud Segmentation for Building Reuse - Construction of digital twins in early phase building reuse projects

summary	Point cloud processing has come a long way in the past years. Advances in computer vision (CV) and machine learning (ML) have enabled its automated recognition and processing. However, few of those developments have made it through to the Architecture, Engineering and Construction (AEC) industry. Here, optimizing those workflows can reduce time spent on early-phase projects, which otherwise could be spent on developing innovative design solutions. Simplifying the processing of building point cloud scans makes it more accessible and therefore, usable for design, planning and decision-making. Furthermore, automated processing can also ensure that point clouds are processed consistently and accurately, reducing the potential for human error. This work is part of a larger effort to optimize early-phase design processes to promote the reuse of vacant buildings. It focuses on technical solutions to automate the reconstruction of point clouds into a digital twin as a simplified solid 3D element model. In this paper, various ML approaches, among others KPConv Thomas et al. (2019), ShapeConv Cao et al. (2021) and Mask-RCNN He et al. (2017), are compared in their ability to apply semantic as well as instance segmentation to point clouds. Further it relies on the S3DIS Armeni et al. (2017), NYU v2 Silberman et al. (2012) and Matterport Ramakrishnan et al. (2021) data sets for training. Here, the authors aim to establish a workflow that reduces the effort for users to process their point clouds and obtain object-based models. The findings of this research show that although pure point cloud-based ML models enable a greater degree of flexibility, they incur a high computational cost. We found, that using RGB-D images for classifications and segmentation simplifies the complexity of the ML model but leads to additional requirements for the data set. These can be mitigated in the initial process of capturing the building or by extracting the depth data from the point cloud.

summary	For most architects, it is not easy to transform their freeform designs into buildable constructions without precise knowledge on a specifi c material and its construction process.A workfl ow is introduced in this paperand it could be adopted by architects concerning the works of predicting the tiling results in the earliest design stage.The workfl ow involves pre-processing which could help architects design rational surfaces, thus saving a lot of work in the paneling process later on. The physically based modeling engine will simulate the constraints of a pre-selected material and therefore ensures a feasible result. The post-process involves visual feedback of the result as well as data formatting which help to establish a seamless connection between construction processes.
