title	Embedding auxetic properties in designing active-bending gridshells
source	SIGraDi 2016 [Proceedings of the 20th Conference of the Iberoamerican Society of Digital Graphics - ISBN: 978-956-7051-86-1] Argentina, Buenos Aires 9 - 11 November 2016, pp.720-726
summary	Advancements in computational tools are offering designers the possibility to change their relationship with materials. The exploration of auxetic metamaterials, specifically engineered to obtain properties beyond those found in nature, is the promising field examined in this paper. The aim is to define tools and methods in order to design auxetics, and use them to create efficient active-bending structures. By programming their geometry through several parameters, it is possible to finely control curvature and structural resistance. The paper describes an original investigation into the process of programming such structures through the use of combined computational tools.

title	Fused Deposition Modelling Formworks for Complex Concrete Constructions
source	SIGraDi 2018 [Proceedings of the 22nd Conference of the Iberoamerican Society of Digital Graphics - ISSN: 2318-6968] Brazil, São Carlos 7 - 9 November 2018, pp. 700-707
summary	Concrete is undoubtedly the most employed material in constructions. In principle it allows to build complex architecture, where form can be for the realization of complex shapes. However, the biggest limitation of its use is explained by the demanding process needed to create free-form casts, it often limits its potential to obvious geometries. With the aim of overcoming current limitations, this paper explores the use of additive manufacturing to create formworks for concrete elements. The case study of a complex column is here utilized in order to develop an approach for advanced molds, where pressure levels, fluid dynamics of concrete and disassembly are integrative part of the design process. In conclusion are presented recommendations for further development at larger scale.

summary	Argentina is one of the countries with more arsenic in its groundwater, having around 4,000,000 people exposed to its unnoticed consumption. Arsenic measurement in private wells is limited by the high costs, the need of specialized personnel and the distance to urban areas. The Industrial design and synthetic biology are combined in an innovative development that uses genetically modified bacteria to detect toxic arsenic levels in drinkable water.

title	Shape Recognition and Transformation: A Script-Based Approach

summary	Design evolves. Architects deploy considerable knowledge to develop their designs from one stage to the next. Drawings play a major role in describing the 11 state" of design at each stage; however, they do not explicitly reveal the knowledge used to achieve the design, for the knowledge is concealed in the "process" between these stages rather than in the drawings themselves. This process involves parametric and schematic transformations as well as perception of unanticipated possibilities emerging from the drawings in progress. To make an impact on design, CAD must address these issues of design knowledge, but so far its focus has been instead on drawings as relatively static collections of graphic primitives. This paper introduces the concepts of shapes and shape transformation as fundamental aspects of design knowledge. It is implemented on a computer program in the form of a prototype shape-scripting language. In summary, this language works as a shell to encode a set of shape categories and their transformations, and it enables progressive shape recognition and shape transformation in line drawings. An appropriate set of these encoded transformations may represent a body of syntactic knowledge about an architectural style. This opens up the exciting possibility of a computational implementation of a shape grammar.

title	Form Processing: A System for Architectural Design
source	Harvard University
summary	This thesis introduces a new approach to developing software for formal synthesis in architectural design. It presents theoretical foundations, describes prototype specifications for computable implementation, and illustrates some examples. The approach derives from the observation that architects explore ideas through the use of sequences of drawings. Architects derive each drawing in a sequence from its predecessor by executing some transformation on a portion of the drawing. Thus, a formal design state is established by a sequence of drawings with historical information about their construction through progressive transformations. The proposed system allows an architect to develop a design in three ways. First, a new transformation can be added to a current sequence of drawings. Second, existing sequences can be edited by exchanging their subset sequences. Third, an existing sequence can be revised parametrically by assigning new values to its design variables. The system implements scripts that specify categories of shapes and transformations between any two shape categories. When an instance of a shape category is found in a design, a transformation can replace it with an instance of another shape category. Recursive application of a given set of transformations to an initial shape instance produces a sequence of drawings that represents a formal design state. The system encodes this formal design state as an assembly of all the shape instances used and their relationships (nesting, emergent and replacement). Furthermore, this assembly, called a construction graph, allows the existing sequences to be edited efficiently by exchanging subsets and to be revised parametrically. The advantage of this approach as demonstrated in the examples is that it allows intuitive, rapid and interactive construction of complex designs. Moreover, design knowledge can be captured by scripts that depict heuristic shapes and transformations as well as by assembled construction graphs which depict cases of formal design. Such a reusable and expandable knowledge base is essential for assisting disciplined and creative architectural design.

summary	The Proceedings of the ACADIA 2017 conference contains peer reviewed research papers presented at the 37th annual conference of the Association for Computer Aided Design in Architecture. Disciplines & Disruption initiates a dialog about the state of the discipline of architecture and the impact of technology in shaping or disrupting design, methods and cultural fronts. For the past 30 years, distinctive advancements in technologies have delivered unprecedented possibilities to architects and enabled new expressions, performance, materials, fabrication and construction processes. Simultaneously, digital technology has permeated the social fabric around architecture with broad influences ranging from digital preservation to design with the developing world. Driven by technological, data and material advances, architecture now witnesses the moment of disruption, whereby formerly distinct areas of operation become increasingly connected and accessible to architecture's sphere of concerns in ways never before possible. Distinctions between design and making, building and urban scale, architecture and engineering, real and virtual, on site and remote, physical and digital data, professionals and crowds, are diminishing as technology increases the designer's reach far beyond the confines of the drafting board. This conference provides a platform to investigate the shifting landscape of the discipline today, and to help define and navigate the future.

title	Digital Dérive. Reconstructing urban environments based on human experience
doi	https://doi.org/10.52842/conf.acadia.2018.072
source	ACADIA // 2018: Recalibration. On imprecisionand infidelity. [Proceedings of the 38th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-0-692-17729-7] Mexico City, Mexico 18-20 October, 2018, pp. 72-81
summary	This paper describes a novel method for reconstructing urban environments based on individual occupant experience. The method relies on a low-cost off-the-shelf 360-degree camera to capture video and audio data from a natural walk through the city. It then uses a custom workflow based on an open-source Structure from Motion (SfM) library to reconstruct a dense point cloud from images extracted from the 360-degree video. The point cloud and audio data are then represented within a virtual reality (VR) model, creating a multisensory environment that immerses the viewer into the subjective experience of the occupant. This work questions the role of precision and fidelity in our experience and representation of a “real” physical environment. On the one hand, the resulting VR environment is less complete and has lower fidelity than digital environments created through traditional modeling and rendering workflows. On the other hand, because each point in the point cloud is literally sampled from the actual environment, the resulting model also captures more of the noise and imprecision that characterizes our world. The result is an uncanny immersive experience that is less precise than traditional digital environments, yet represents many more of the unique physical characteristics that define our urban experiences.

title	Beyond Heuristics: A Novel Design Space Model for Generative Space Planning in Architecture
doi	https://doi.org/10.52842/conf.acadia.2017.436
source	ACADIA 2017: DISCIPLINES & DISRUPTION [Proceedings of the 37th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-0-692-96506-1] Cambridge, MA 2-4 November, 2017), pp. 436- 445
summary	This paper proposes a novel design space model that can be used in applications of generative space planning in architecture. The model is based on a novel data structure that allows fast subdivision and merge operations on planar regions in a floor plan. It is controlled by a relatively small set of input parameters and evaluated for performance using a set of congestion metrics, which allows it to be optimized by a metaheuristic such as a genetic algorithm (GA). The paper also presents a set of guidelines and methods for analyzing and visualizing the quality of the model through low-resolution sampling of the design space. The model and analysis methods are demonstrated through an application in the design of an exhibit hall layout. The paper concludes by speculating on the potential of such models to disrupt the architectural profession by allowing designers to break free of common "heuristics" or rules of thumb and explore a wider range of design options than would be possible using traditional methods.

title	A Collaborative Approach to Digital Fabrication:A Case Study for the Design and Production of Concrete ‘Pop-up’ Structures
source	International Journal of Architectural Computing vol. 13 - no. 2, 195-216
summary	The research presented in this paper utilizes industrial robotic arms and new material technologies to model and explore a prototypical workflow for on-site robotic collaboration based on feedback loops. This workflow will ultimately allow for the construction of customized, free-form, on-site concrete structures without the need for complex formwork. The paper starts with an explanation of the relevance of collaborative robotics through history in the industry and in architecture. An argument is put forward for the need to move towards the development of collaborative processes based on feedback loops amongst the designer, the robot and the material, where they all inform each other continuously. This kind of process, with different degrees of autonomy and agency for each actor, is necessary for on-site deployment of robots. A test scenario is described using an innovative material named concrete canvas that exhibits hybrid soft fabric and rigid thin-shell tectonics. This research project illustrates the benefits of integrating information-embedded materials, masscustomization and feedback loops. Geometry scanning, parametric perforation pattern control, computational analysis and simulation, and robotic fabrication were integrated within a digital fabrication deployment scenario. The paper concludes with a detailed report of research findings and an outline for future work.

title	Automated Generation of Custom Fit PPE Inserts
doi	https://doi.org/10.52842/conf.acadia.2021.048
source	ACADIA 2021: Realignments: Toward Critical Computation [Proceedings of the 41st Annual Conference of the Association of Computer Aided Design in Architecture (ACADIA) ISBN 979-8-986-08056-7]. Online and Global. 3-6 November 2021. edited by B. Bogosian, K. Dörfler, B. Farahi, J. Garcia del Castillo y López, J. Grant, V. Noel, S. Parascho, and J. Scott. 48-57.
summary	This research presents a machine learning-based interactive design method for the creation of customized inserts that improve the fit of the PPE 3M 1863 and 3M 8833 respiratory face masks. These two models are the most commonly used by doctors and professionals during the recent covid19 pandemic. The proper fit of the mask is crucial for their performance. Characteristics and fit of current leading market brands were analyzed to develop a parametric design software workflow that results in a 3D printed insert customized to specific facial features and the mask that will be used. The insert provides a perfect fit for the respirator mask. Statistical face meshes were generated from an anthropometric database, and 3D facial scans and photos were taken from 200 doctors and nurses on an NHS trust hospital. The software workflow can start from either a 2D image of the face (picture) or a 3D mesh taken from a scanning device. The platform uses machine learning and a parametric design workflow based on key performance facial parameters to output the insert between the face and the 3M masks. It also generates the 3d printing file, which can be processed onsite at the hospital. The 2D image approach and the 3D scan approach initializing the system were digitally compared, and the resultant inserts were physically tested by 20 frontline personnel in an NHS trust hospital. Finally, we demonstrate the criticality of proper fit on masks for doctors and nurses and the versatility of our approach augmenting an already tested product through customized digital design and fabrication.

title	Multiview databases for building modelling
source	Automation in Construction 8 (5) (1999) pp. 567-579
summary	Database systems provide various facilities including modelling data, queries, semantic integrity control, concurrency control, recovery and authorisation. The transition from relational database technology to object technology is characterised by a richer data model to meet the requirements of new applications such as computer-aided design (CAD) systems. However, object technology still has several shortcomings. One of these shortcomings is that conventionally object model is not able to deal with data that can be described and queried according to different viewpoints. The building practice, for example, is characterised by the organisation of different participants that work towards the elaboration of the building; each one performs a specific role and has a specific view on the building project data. This paper proposes the CEDAR model, which specifies object-oriented multiview databases that can represent data and ensure their integrity according to different viewpoints. The approach is illustrated with an outline of a building project.

source	Challenges of the Future [15th eCAADe Conference Proceedings / ISBN 0-9523687-3-0] Vienna (Austria) 17-20 September 1997
summary	The decisions made at the early stages of design that generally take place in the architectural office have phenomenal effects on many aspects of building, including the structural form, the mechanical and electrical services, the construction planning, and the overall cost of the project. It is of prime importance that the effect of decisions which an architect makes in the initial stages of building design can be assessed; particularly vital is the influence of changes made in the spatial arrangement of building floors. The earlier in the design process these effects are studied, the better the later difficulties can be avoided. A programme of research is in progress to provide a computer-aided learning tool for students of architecture so that they become familiar with the process of structural design, and examine the effects of the decisions they make at the initial stages of design on the structure of the building. It is also educative to observe how the architectural design of a building may be influenced by its structural arrangement. It is intended that the user acquire a general understanding of how steel structures behave.

summary	The Adaptive Solar Façade (ASF) as an integrated dynamic and flexible building facade could be a hopeful design tool to provide residents comfort and energy efficiency by applying relevant integrated parametric design. Based on that, in this study, we investigated a designing process and optimization of ASF concentrating on providing the visual comfort and energy efficiency. We start with an extended summary of previous studies which has been done for developing a dynamic system correspond to origami and butterfly wings. Afterwards, we design 10 movement patterns for façade at the next stage, we simulate the Illuminance uniformity distribution and amount of energy consumption in the interior area. It should be noted that this simulation is done hourly. Therefore, 52 base models were investigated in Hamedan without using intelligent façade. It should be considered that these models are offices and they are investigated in the cold tundra in four days of the year between 6 A.M. to 6 P.M. Afterwards, 520 façade affected proposed models simulated for comparing to the base model. We have done the latter simulation using Colibri plugin while it optimized linearly. All of the datasets have been processed in an algorithm circulation for analyzing the simulations results.

title	A Novel Design-Based Optimization Solution for Building by Sensitivity Analysis
source	Hybrid Spaces of the Metaverse - Architecture in the Age of the Metaverse: Opportunities and Potentials [10th ASCAAD Conference Proceedings] Debbieh (Lebanon) [Virtual Conference] 12-13 October 2022, pp. 632-653
summary	The important objective of a building must be to provide a comfortable environment for people. Heating, ventilation and air conditioning (HVAC) systems provide a comfortable environment, but they are using high energy consumption, therefore, designing an energy-efficient building that balances energy performance and thermal comfort is necessary. To achieve this subject is important to choose the effective parameters for energy performance. This research aim is to produce a methodology for multi-objective optimization of daylight and thermal comfort in order to study the effect of wall material and shading of an office building (Tehran a basic-location). The building simulation was developed and validated by comparing predicted daylight hours and thermal comfort hour based on test and training on Jupiter Notebook (Anaconda3). The sensitivity analysis uses a multiple linear regression (MLR) method. Secondly, optimization is based on a genetic algorithm (GA) with the effective parameters to optimize the daylight and thermal comfort performance. For this, we developed a parametric model using the Grasshopper plugin for Rhino and then use Honeybee and Ladybug plugins to simulate thermal comfort and daylight, at the end use the Octopus engine to find an optimization solution. The result of this paper is essential as a preliminary analysis for shading devices, window-to-wall ratios, and wall construction optimization in the open-plan office.

summary	Mixed reality (MR), which blends real and virtual worlds, has attracted attention as a visualization method in landscape design. MR-based landscape visualization enables stakeholders to examine landscape changes at actual scale in real-time at the actual project site. One challenge in MR-based landscape visualization is occlusion, which occurs when virtual objects obscure physical objects that are in the foreground. Previous research proposed an MR-based landscape visualization method with dynamic occlusion by using semantic segmentation of deep learning. However, this method has two problems. The first is that the same kind of objects that are grouped into one or overlapped types are classified as the same object, and the other is that the foreground objects have to be defined in pre-processing. In this study, we developed a system for large-scale MR landscape visualization that enables the recognition of each physical object individually using instance segmentation, and it is possible to accurately represent the positional relationship by comparing the coordinate information of the 3D virtual model and all physical objects.

title	Two-Dimensional Spatial Positioning as a Means for Reflection in Design Design Cases
source	Proceedings of DIS'00: Designing Interactive Systems: Processes, Practices, Methods, & Techniques 2000 pp. 145-154
summary	In the realm of computer support for design, developers have focused primarily on power and expressiveness that are important in framing a design solution. They assume that design is a series of calculated steps that lead to a clearly specified goal. The problem with this focus is that the resulting tools hinder the very process that is critical in early phases of a design task; the reflection-in-action process [15]. In the early phases, what is required as the most important ingredient for a design tool is the ability to interact in ways that require as little commitment as possible. This aspect is most evident in domains where two dimensions play a role, such as sketching in architecture. Surprisingly, it is equally true in linear domains such as writing. In this paper, we present our approach of using two-dimensional positioning of objects as a means for reflection in the early phases of a design task. Taking writing as an example, the ART (Amplifying Representational Talkback) system uses two dimensional positioning to support the early stages of the writing task. An eye-tracking user study illustrates important issues in the domain of computer support for design.

summary	Facility management is aimed at energy saving, increasing the lifespan of buildings, enhancing the satisfaction of facility users and reducing running costs. To that end, it is important to grasp the conditions of the building in detail, and to analyze them one by one in order to execute building operation and maintenance strategically. However, conventional CAFM is insufficient. Therefore, we developed a system (called Building Information Management System) to utilize BIM data made in BIM-CAD on a Web site. We used groupware to support the system and an information platform that enables flexible management of a great variety of maintenance information. In addition, we developed an environmental measurement module and built a structure to sensor information automatically by using a development system. For quality maintenance, detailed information of building operation and maintenance is both from human input and sensors. The proposed method analysis of a building and provides the foundation for strategic control of maintenance.

summary	Recently more researches on tangible objects have been conducted that enhance the intuitive polygonal or surface modelling of designers in digital and physical worlds. However, a few researches have been done that augment the digital solid modelling with tangible objects. In this paper, we present the Augmented Solid Modeller (ASoM) which helps designers create more complex shapes by a combination of Boolean operations between a different type of 3D-printed tangible objects, which is different from the conventional single shape type bottom-up modelling approaches. When multiple objects intersect each other at a given position and angle, the interference or removed shape is often unexpected for designers. Also, as 3D-printed objects are used for designers only to configure and discuss the shape of final digital 3D model in existing CAAD, ASoM changes the role of 3D-printed objects from the replicas to reusable tools for other modelling opportunities. We offered ASoM to students majoring or interested in CAAD and interviewed them to get comments. Since the speed and precision of 3D-printing will achieve immediate improvement, ASoM is a pioneer in developing cutting-edge approach for designers to model both in digital and physical worlds.

summary	In the current computer-aided architectural design education, students do not necessarily need to be taught to use more digital tools, but need to be introduced to the possibilities of designing their own digital tools. Designing the original tools with the assistance of educational-use environment for computational fluid dynamics programming improves the capability of the students to estimate the flows around architectures based on the mathematical background and the actual program. The authors have developed Educational Library for Fluid as an educational-use environment for computational fluid dynamics programming and ran the workshop where the students majoring in computer-aided architectural design tried to design computational fluid dynamics tools with Educational Library for Fluid. In this article, the details of Educational Library for Fluid and the results of the workshop are being reported. In addition, the key points of computational fluid dynamics education that the authors learned through the experience of the workshop are shared.
