title	Building Services Standard Solutions. Variational Generation of Plant Room Layouts
source	Proceedings of the Ninth International Conference on Computer Aided Architectural Design Futures [ISBN 0-7923-7023-6] Eindhoven, 8-11 July 2001, pp. 479-493
summary	Object-based CAD programming is used to take advantage of standardisation to handle the schematic design, sizing, layout and (potentially) pipe-routing for LPHW (Low Pressure Hot Water) plant rooms in buildings. From a simple specification of the plant room geometry, and the heating load in kw, our software proceeds through a number of steps. First the standard number and size of modular boilers, pumps etc. is determined from the heat load. Then a compatible optimising 3D variational solution is generated, using Constraint Logic Programming. Our approach is highly interactive. Modifying the topology of the solution is done directly through the graphic interface, e.g. modifying a boiler position is done by dragging; the system automatically updates the 3D model including the pipe-routing while maintaining all the constraints, and hence the validity of the design.

title	Interactive 2D Constraint-Based Geometric Construction System
source	Proceedings of the Eighth International Conference on Computer Aided Architectural Design Futures [ISBN 0-7923-8536-5] Atlanta, 7-8 June 1999, pp. 197-212
summary	This paper presents a 2D Constraint-Based Geometric Construction System where positioning and manipulating geometry is very precise. An unusually simple interface makes this system particularly interactive and easy to use. In our approach, the geometry types supported are: points, lines, circles, ellipses, circular arcs and b-spline curves. All the fundamental topologic constraints, i.e. tangent, parallel, perpendicular, coincident and concentric, are provided. Metric constraints, i.e. dividing the shapes into equal parts or fixing the geometric parameters, are also provided. These constraints are automatically applied by the application in response to the implied intentions of the end- user. Dynamic modifications of partially dimensioned models are supported, whereby the design is modified while enforcing the constraints. A graph-constructive approach is used to solve the model. As we are dealing with partial modifications, this resolution technique is quite sufficient, and makes our system stable and flexible. Our approach focuses highly on interactivity. Positioning a shape constrained to another is made directly through the graphic interface. Constraint relaxation is also done by direct manipulations. Modifications are made by dragging the geometry, or by typing into a numerical panel displaying the free shape parameters. Again, existing constraints are maintained as those numbers are applied. Well -constrained and under-constrained problems are discussed. This approach was developed in Java, JDK 3.0.1 of SGI's Java software.

title	Strong-rooms project: sizing and calculation of components
source	SIGraDi 2005 - [Proceedings of the 9th Iberoamerican Congress of Digital Graphics] Lima - Peru 21-24 november 2005, vol. 1, pp. 173-177
summary	This paper deals with a project that has been done to Aceco TI Ltda`s company. It is about a software development, in AutoLisp programming language (under AutoCAD´s platform), which helps to the project and calculation of strong-rooms components. Those rooms are completely sealed, making use of high technologies materials as sealing, allowing computational equipments and enclosed information to be protected. The developed programme contains routines that allow the precise dimension of structural component, as floors, walls, doors and ceilings. Therefore, it is possible to fabricate special pieces with accuracy. Moreover, the programme calculates a series of other components as friezes, drips, luminaries, sealing tapes and silicone conduits. Then, yonder saving time on project, this system allows, on the one hand, each piece to be produced in factory with exactness accuracy, making assembly easier. On the other hand, allows assembly to be started with all necessary elements, reducing time and costs. [Full paper in Portuguese]

title	Digital Media in Architecture: Digital Media and Interactive Design Communication System in Design Process for Architectural Practices
doi	https://doi.org/10.52842/conf.caadria.2015.033
source	Emerging Experience in Past, Present and Future of Digital Architecture, Proceedings of the 20th International Conference of the Association for Computer-Aided Architectural Design Research in Asia (CAADRIA 2015) / Daegu 20-22 May 2015, pp. 33-42
summary	At present in most architectural practices, the way architectural design is presented involves computer-aided design to describe architecture for different purposes. Digital media has been employed for a creative proposal to achieve efficient communication. Although architects conduct and navigate design information, communication can be more efficient if architects convey exact messages. This paper investigates the way that architects communicate with stakeholders exploring their needs, including in digital media design to suggest new approaches that exploit capability of digital interactive media and networking. There is a clear need for a design process that ensures accurate communication, where both professionals and stakeholders can interact while the architectural design process is in progress. All stakeholders, not just architects need to be able to navigate the process. Finding a communication system through a website or application is recommended for this study.

title	Rethinking Airport Spatial Analysis and Design: A GAN based data driven approach using latent space exploration on aerial imagery for adaptive airport planning
doi	https://doi.org/10.52842/conf.ecaade.2023.2.501
source	Dokonal, W, Hirschberg, U and Wurzer, G (eds.), Digital Design Reconsidered - Proceedings of the 41st Conference on Education and Research in Computer Aided Architectural Design in Europe (eCAADe 2023) - Volume 2, Graz, 20-22 September 2023, pp. 501–510
summary	Airports require long term planning, balancing estimations of future demand against available airfield land and site constraints. This is becoming more critical with climate change and the transition to sustainable aviation fuelling infrastructure. This paper demonstrates a novel procedure using Satellite Imagery and Generative Learning to aid in the comparative analysis and early-stage airfield design. Our workflow uses a GAN trained on 2000 images of airports transforming them into a high-dimensional latent space capturing the typologies’ large-scale features. Using a process of projection and dimensional-reduction methods we can locate real-world airport images in the generative latent space and vice-versa. With this capability we can perform comparative “neighbour” analysis at scale based on spatial similarity of features like airfield configuration, and surrounding context. Using this low-dimensional 3D ‘airport designs space’ with meaningful markers provided by existing airports allows for ‘what if’ modelling, such as visualizing an airport on a site without one, modifying an existing airport towards another target airport, or exploring changes in terrain, such as due to climate change or urban development. We present this method a new way to undertake case study, site identification and analysis, as well as undertake speculative design powered by typology informed ML generation, which can be applied to any typologies which could use aerial images to categorize them.

title	Machine Learning for Comparative Urban Planning at Scale: An Aviation Case Study

summary	Aviation is in flux, experiencing 5.4% yearly growth over the last two decades. However, with COVID-19 aviation was hard hit. This, along with its contribution to global warming, has led to louder calls to limit its use. This situation emphasizes how urban planners and technologists could contribute to understanding and responding to this change. This paper explores a novel workflow of performing image-based machine learning (ML) on satellite images of over 1,000 world airports that were algorithmically collated using European Space Agency Sentinel2 API. From these, the top 350 United States airports were analyzed with land use parameters extracted around the airport using computer vision, which were mapped against their passenger footfall numbers. The results demonstrate a scalable approach to identify how easy and beneficial it would be for certain airports to expand or contract and how this would impact the surrounding urban environment in terms of pollution and congestion. The generic nature of this workflow makes it possible to potentially extend this method to any large infrastructure and compare and analyze specific features across a large number of images while being able to understand the same feature through time. This is critical in answering key typology-based urban design challenges at a higher level and without needing to perform on-ground studies, which could be expensive and time-consuming.

title	A framework to evaluate the architect-friendliness of environmental impact assessment tools for buildings
doi	https://doi.org/10.52842/conf.ecaade.2017.1.425

summary	Legal actions towards a mandatory environmental impact assessment (EIA) of buildings can be expected in the (near) future. Due to the complexity of EIA, software tools will become an indispensable aid in the architectural design process. Especially in early design, feedback on the environmental impact is needed, since early design decisions have a major influence on the final impact of the design. However, most existing EIA tools insufficiently take into account the architect's needs as a user and are especially not suitable for use in early design. Therefore, an evaluation framework with criteria for architect-friendliness of EIA tools, with a specific focus on early design, is developed based on a large-scale survey, interviews and a focus group with practising architects. This framework can be used to evaluate the architect-friendliness of existing EIA tools and as a guidance for the development of new architect-oriented tools.

summary	This research discusses how expatriates living in Sharjah intervene with the urban landscape through practices that allow them to take possession of that place-space and use it as a discourse to consolidate their identity. A thorough documentation of the urban sprawl of one of the major arteries of Sharjah was used as a means to collect imagery that portrays the human appreciation of the environment. A design-urban intervention was used as a discursive instrument to entitle us to make visible (and thus tangible) the transition from a simple sign of cultural identity into a memory for a collective society.

title	Contextual customization of design process. Design through the digital and the material
source	FUTURE TRADITIONS [1st eCAADe Regional International Workshop Proceedings / ISBN 978-989-8527-03-5], University of Porto, Faculty of Architecture (Portugal), 4-5 April 2013, pp. 205-216
summary	In contemporary world, digital technologies have initiated new architectural languages and have eased the way to communicate them directly from initial design phase to production facilities, allowing for the construction of complex geometries with the use of ever evolving techniques and tools. When the emergence of a substance depends on the material behavior, the design interest shifts towards the ‘formation’ instead of the ‘final form’. Regarding these the design procedures will be discussed from the premise where architecture will be perceived through an evolution process that deals with the coherent variables of elements and shifting parameters within a context. However, there are crucial questions about its application in the contexts which have lower access to contemporary technologies although digital technology has already influenced almost every aspects of the culture of the respective context. Besides, the huge production cost has limited its adaptability in many under developed and developing countries where the construction field relies mainly on traditional and low-tech methods. The paper is an effort to give attention on exploration of the new-found freedoms of material computation in close connection with the respective context by inventing new design processes, material applications and custom devices. It is the time to experiment with flexible, mobile and low-cost fabrication methods applicable to different scenarios while achieving the complexity of the contemporary architectural ge¬ometries. Thus an equal focus has to be given to speculate about projects that are site-specific, custom¬ized and adapted to local climatic conditions and technical know-how, in areas that traditionally have limited access to new technologies.

title	An Exploration Into Computational Optimization for Motive Architecture
doi	https://doi.org/10.52842/conf.acadia.2012.401
source	ACADIA 12: Synthetic Digital Ecologies [Proceedings of the 32nd Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-1-62407-267-3] San Francisco 18-21 October, 2012), pp. 401-405
summary	This paper explores the potential of advanced computational methods for architecture. An experiment has been conducted with the aim of applying a computer driven optimization process on the motive behavior of a physical prototype. The choice of the mechanism is arbitrary, and this is to convey that the adaptive behavior of a structure in real time may be improved with the appropriate computational methods, regardless of its mechanical complexity. This provides architects with the opportunity to bring previously static architectural concepts into motion. The paper looks into the fields of embodied AI and mobile robotics research as resources for knowledge on the notions of integrating evolutionary computation into physical artifacts.

summary	In the context of the growing usefulness of computation within architecture, structures face the potential for being conceived of as intelligent entities capable of resilient, adaptive behavior.Building on this idea, this work explores the use of machine learning for structures that may learn to autonomously “stand up”. The hypothesis is that a neural network with genetically optimized weights would be capable of teaching lightweight, flexible, and unanchored structures to self-rectify after falling, through their interactions with their environment. The experiment devises a physical and a simulated prototype. The machine-learning algorithm is implemented on the virtual model in a three-dimensional physics environment, and a solution emerges after a number of tests. The learned behavior is transferred to the physical prototype to test its performance in reality. This method succeeds in allowing the physical prototype to stand up. The findings of this process may have useful implications for developing embodied dynamic structures that are enabled with adaptive behavior.

summary	Skin is the primary shield between our body and its surroundings. It protects the body from the harmful environmental effects like dehydration and radiation from intense sunlight. Likewise, the outer layer, or skin of a building has the same function of protecting its inhabitants against the external elements. This research is a part of a larger investigation into geometrical patterning and layering of facades as an effective intervention between the outdoor space and the indoor environment to regulate the conditions for occupant thermal comfort. This paper reports on exploration of an approach for measurement, evaluation and feedback in the design workflow through a mixed digital -physical simulation platform (MDPS) based on the objectives of the larger study. For this purpose, it introduces a new way of analyzing thermal performance of double skin facades by using temperature sensors, Arduino, post visualization with MATLAB and digital energy simulation. The main aspects of this proposed workflow is the design of a thermal performance feedback loop as an integral part of the process of geometrical patterning design for façade.

summary	In the modern urbanization process, urban planners create rules to define urban form and composition of blocks which are greatly impacted by the road network. This research paper proposes a "city generator", as an urban design toolkit for urban designers to make prototypes of large new town planning and reimagination of city generation. The generator aims to translate planning regulations into three-dimensional urban form and provide users with efficient and intuitive design iterations. Moreover, our generator emphasizes consistency in generation across scales. From a single block to a district, they can be produced in one operation without losing details. Finally, the generator provides a great degree of freedom for users to manipulate, including three aspects - road generation, density mapping and building form. Because of the flexibility of input parameters, generated models can be a rigid urban grid or an organic pattern, which can highly satisfy urban designer's expectations and imagination.

summary	Digital Vernacular investigates the potential of the process of depositing a paste like material with precision using a CNC device which has produced an innovative system for design and fabrication of environmentally responsive housing. Architectural practice has been greatly impacted by technical innovations in the past, usually new building types emerge as part of new ideologies. Yet the current revolution in computer-aided design and fabrication has architecture focusing on form – without questioning what these new processes can bring for the masses. The research project 'Digital Vernacular' has investigated the potential of using CNC technology for the production of housing. It has focused on the design of the machinic devices as well as computational design tools, and revolves around the concept of fabrication on site. Using an additive and layered manufacturing process and locally available material, the project proposes a revolutionary new digital design and fabrication system that is based on one of the oldest and most sustainable construction methods in the world. The main potentials of this method are not to create complex forms for the sake of design, but to use parametric control to adapt each design to the specificities of its site. Using geometrical rules found during many research experiments with real material behaviour, a new architectural language is created that merges several environmental functionalities into a single integrated design.

summary	This paper presents a computational design approach and a digital fabrication method for a freeform aluminum facade made of prefabricated bespoke elements. The fabrication of customized metal elements for construction remains a challenge to this day. Traditional fabrication methods, such as sand casting, are labor intensive, while direct metal 3D printing has limitations for architecture where large-scale elements are needed. Our research investigates the use of Binder Jetting technology to 3D print sand molds for casting bespoke facade elements in aluminum. Using this approach, custom facade elements can be economically fabricated in a short time. By automating the generation of mold design for each element, an efficient digital process chain from design to fabrication was established. In search of a computational method to integrate casting constraints into the form generation and the design process, a differential growth algorithm was used. The application of this fabrication method (3D printed sand molds and casting) in architecture is demonstrated via the design and fabrication of a freeform facade-screen. The paper articulates the relationship between the fabrication process and the differential growth algorithm with a parallel process of adaptive design tools and fabrication tests to exhibit future potential of the method for architectural practice.

title	Smart Slab. Computational design and digital fabrication of a lightweight concrete slab
doi	https://doi.org/10.52842/conf.acadia.2018.434
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. 434-443
summary	This paper presents a computational design approach and novel digital fabrication method for an optimized lightweight concrete slab using a 3D-printed formwork. Smart Slab is the first concrete slab fabricated with a 3D-printed formwork. It is a lightweight concrete slab, displaying three-dimensional geometric differentiation on multiple scales. The optimization of slab systems can have a large impact on buildings: more compact slabs allow for more usable space within the same building volume, refined structural concepts allow for material reduction, and integrated prefabrication can reduce complexity on the construction site. Among the main challenges is that optimized slab geometries are difficult to fabricate in a conventional way because non-standard formworks are very costly. Novel digital fabrication methods such as additive manufacturing of concrete can provide a solution, but until now the material properties and the surface quality only allow for limited applications. The fabrication approach presented here therefore combines the geometric freedom of 3D binderjet printing of formworks with the structural performance of fiber reinforced concrete. Using 3D printing to fabricate sand formwork for concrete, enables the prefabrication of custom concrete slab elements with complex geometric features with great precision. In addition, space for building systems such as sprinklers and Lighting could be integrated in a compact way. The design of the slab is based on a holistic computational model which allows fast design optimization and adaptation, the integration of the planning of the building systems, and the coordination of the multiple fabrication processes involved with an export of all fabrication data. This paper describes the context, design drivers, and digital design process behind the Smart Slab, and then discusses the digital fabrication system used to produce it, focusing on the 3D-printed formwork. It shows that 3D printing is already an attractive alternative for custom formwork solutions, especially when strategically combined with other CNC fabrication methods. Note that smart slab is under construction and images of finished elements can be integrated within couple of weeks.

summary	3D printing offers significant geometric freedom and allows the fabrication of integral parts. This research showcases how robotic fused deposition modeling (FDM) enables the prefabrication of large-scale, lightweight, and ready-to-cast freeform formwork to minimize material waste, labor, and errors in the construction process while increasing the speed of production and economic viability of casting non-standard concrete elements. This is achieved through the development of a digital design-to-production workflow for concrete formwork. All functions that are needed in the final product, an integrally insulated steel-reinforced concrete wall, and the process for a successful cast, are fully integrated into the formwork system. A parametric model for integrated structural ribbing is developed and verified using finite element analysis. A case study is presented which showcases the fully integrated system in the production of a 2.4 m tall x 2.0 m curved concrete wall. This research demonstrates the potential for large-scale additive manufacturing to enable the efficient production of non-standard concrete formwork.

title	Robotic 3D Printing Multilayer Building Envelope

University of Pennsylvania Stuart Weitzman School of Design. 27-29 October 2022. edited by M. Akbarzadeh, D. Aviv, H. Jamelle, and R. Stuart-Smith. 34-43.
summary	This research explores the use of robotic pellet extrusion 3D printing (3DP) in the production of a multifunctional thermoplastic building envelope. A computational design method was developed to generate multi-layered systems of interconnected volumes using minimal surfaces, combined with a rib-stiffening approach that accommodates fabrication constraints. The investigation highlights the development of an integrated system that includes robotic end-effector tooling, programming/control methods to allow “endless” prints, as well as specific toolpath strategies to improve print speed and quality. These developments are then demonstrated through the design and fabrication of two 2.2 m by 1.1 m building envelope panels, and the results are discussed along with specific details of the printing process. The innovations of this research are: (1) a computational design tool that allows intuitive generation and adaptation of multilayer building envelopes to site criteria; and (2) a robust robotic control system allowing continuous, uninterrupted printing at architectural scale with minimal supervision and high-quality surface finish.

summary	The purpose of this paper is to make apparent critical and theoretical aspects of the instrumentation of new technologies inside architectural processes. After twenty five years of “Choral Work” between architecture and post-structuralist philosophy superimposed together inside architectural processes, we now face a new technological era which seems to provide a new figure of authority by replacing logocentrism to mathematical logicocentrism. Everywhere, the “insemination” of computer by biogenetic algorithms and codification processes transform matter into a zoocentric paradigmatic system, which is supposed, by its internal “modulation,” to extend our potential of social dynamics into space. The goal of our demonstration will then be to examine new technical and theoretical strategies, in a way that the positivistic structure of computation can avoid a totalizing effect (that leading architecture under technological domination), but open up to an un-programmable (emergent) future far above “weaving” and calculated design.

summary	This paper presents the hypothesis part of an expert-system for detailing reinforced concrete structures. The structural members on which the work is focused are columns. To generate a hypothesis - that means to configurate the reinforcement for a given structural member with an almost fixed geometry - needs different kinds of information, i.e. knowledge and a strategy to apply this knowledge. Therefore a hybrid system is chosen which combines object oriented organization to represent the fixed knowledge and a rule base to model the strategy and the dynamic knowledge.
