title	Solid Modeling of Architectural Design with PLASM Language
source	Computer Aided Architectural Design Futures: Education, Research, Applications [CAAD Futures ‘91 Conference Proceedings / ISBN 3-528-08821-4] Zürich (Switzerland), July 1991, pp. 203-224
summary	PLASM (Programming LAnguage for Solid Modeling) is a prototype, high level, user oriented, functional design language currently being developed at the University of Rome "La Sapienza". A PLASM "program" is the symbolic definition of a complex of variational polyhedra depending on some unbound variable, and therefore allows for the description of a whole set of geometric solutions to a design problem. In our view the language should be used, possibly with the assistance of a graphical user interface, both in the first steps of the design process as well in the detailed design. In the paper the guide-lines are shown for the preliminary definition of the syntax of the language. The paper also contains the definition of some new and very powerful solid operators.

title	A METHOD FOR REAL TIME SPATIAL ANALYSIS OF SOUND VIA MODELING IN A CAD ENVIRONMENT, BASED ON ACOUSTICAL MEASUREMENTS
source	14th European Colloquium on Theoretical and Quantitative Geography,September 9-13, 2005, Tomar, Portugal
summary	Typical modeling systems for spatial analysis employ data that represent the visual part of a landscape (e.g. relief and morphology), combined with other data about specific attributes (depending on the aims of an application). Thus, in a modeling environment, each place is described by a variety of properties that are not always visible. More of those “hidden” properties require special sensors and/or instruments to be captured and sometimes make their presence evident through human senses, such is sound. The present study takes advantage of wide spread technologies (such as GPS, VHF telecommunications and field sensors) and methodologies that are commonly used in telegeoprocessing – telegeomonitoring in order to simulate an existing acoustic environment. The aim is to acquire real time data about the sound (referenced to a particular area) and manipulate them in a CAD environment with purpose to visualize the sound influence in a specific landscape. Specifically it is proposed a method that transfers spatial data (collected from the field), directly into a modeling system (in the office, or in situ). In sequence the data is processed adequately to feed the modeling system that describes the current sound intensity of a place.

title	Self-Healing” Processes for the Cityscape - Computationally driven collective initiatives
source	Parametricism Vs. Materialism: Evolution of Digital Technologies for Development [8th ASCAAD Conference Proceedings ISBN 978-0-9955691-0-2] London (United Kingdom) 7-8 November 2016, pp. 505-512
summary	The subject of this paper describes a proposal on processes and strategies that a community should inherit towards a collective effort for the improvement of public space, in order to evaluate, preserve or cancel actions towards this scope of their personal, and extended, scenery. This project, within the spectrum of what an era, underlined by (financial) crisis, represents, is an experiment on the active cooperation of the citizens for their own benefit. That affects, amongst others, the social and public management of space, by creating and activating a community’s feeling of “ownership and responsibility” within its neighborhood. It is expected to achieve an intense caring environment both for the public space, and the extended private scenery. Identifying the tools for actions as such, there comes the necessity for them to be able to make the interested parties feel comfortable with the main artifact and challenge them for collaboration. The digital era, the social media power, as well as the need of the individuals towards networking and belonging, shall perform the main attraction to the subject, leading to the creation of a digital tool linking the people actively to the changes they want to see. This paper debates on the development of an application that enables citizens to take part on the well-being of the(ir) public space.

title	Managing Actors and Building Information for Supply Chain Integration
source	Parametricism Vs. Materialism: Evolution of Digital Technologies for Development [8th ASCAAD Conference Proceedings ISBN 978-0-9955691-0-2] London (United Kingdom) 7-8 November 2016, pp. 187-196
summary	Supply Chain (SC) integration has been a long-standing issue. With the advent of Building Information Modelling (BIM) and its influence on inter-organisational relations, SC integration is again highly relevant. This study explores the conditions for SC integration from deploying BIM and SC management (SCM) philosophy. A set of topics from literature, pertinent to BIM and SCM, are confronted with the experiences of experts from the industry during a workshop. The bottom-up BIM initiatives and relational management were deemed more decisive than adhering to top-down BIM policies and operational SCM for managing actors and information and inciting SC integration.

title	Objects-to-sense-with - Computational Tools for Embodied Spatial Learning
doi	https://doi.org/10.52842/conf.ecaade.2016.1.367
source	Herneoja, Aulikki; Toni Österlund and Piia Markkanen (eds.), Complexity & Simplicity - Proceedings of the 34th eCAADe Conference - Volume 1, University of Oulu, Oulu, Finland, 22-26 August 2016, pp. 367-376
summary	This paper proposes objects-to-sense-with as tools that provide sensory-based learning of space and expand spatial knowledge beyond merely the formal and visual aspects currently dominant in design discourse. To reintroduce sensory-based learning methods in architecture education, this paper first revisits the sensory pedagogies formulated in the early 20th century, reviews precedents in the arts that utilize body-centered sensing technologies, and reframes previous discussions on the pedagogical role of technologies as tools for thinking. Finally, this paper describes the development of a wearable tool with embedded sensors created by the author and describes how the results are visualized. The developed tool, which is used to record sensory data in-situ by the user and allows for a body-centered representation of space, serves as an example of an object-to-sense-with that can be used to achieve a sensory-based and body-centered understanding of architecture.

title	Mobile Augmented Heritage: Enabling Human Life in Ancient Pompeii
source	International Journal of Architectural Computing vol. 5 - no. 2, pp. 396-415
summary	We propose a new methodology for real-time mobile mixed reality systems that feature realistic simulations of animated virtual human actors (clothes, body, skin, face) who augment real environments and re-enact staged storytelling dramas. Although initially targeted at Cultural Heritage Sites, the paradigm is by no means limited to such subjects. The abandonment of traditional concepts of static cultural artifacts or rigid geometrical and 2D textual augmentations with 3D, interactive, augmented historical character-based event representations in a mobile and wearable setup, is the main contribution of the described work as well as the proposed extensions to AR Enabling technologies: a VR/AR character simulation kernel framework with character to object interaction, a markerless camera tracker specialized for non-invasive geometrical registration on heritage sites and a PRT mixed reality illumination model for more consistent real-virtual real-time rendering. We demonstrate a real-time case study on the actual site of ancient Pompeii.

title	Digital Territories and the Design Construction Continuum
doi	https://doi.org/10.52842/conf.ecaade.2006.168
source	Communicating Space(s) [24th eCAADe Conference Proceedings / ISBN 0-9541183-5-9] Volos (Greece) 6-9 September 2006, pp. 168-174
summary	The purpose of the paper is to bring together the two newly elaborated concepts of Digital Territories (DT) and Design Construction Continuum (DCC) in order to approach the design of evolving – intelligent environments.Digital Territories is a concept elaborated 2005 by a Core Expert Group, conceived as an ephemeral Ambient Intelligence (AmI) space. DTs formed through the interconnection of physical objects embedding digital technologies, postulate the integration of the physical and the digital world, searching for operative definitions of new evolving in time functionalities. In DT’s, bridges between the physical and the digital are discrete elements disposing of certain autonomy in their conception and internal structure. Bridges have to be designed and located. The DCC proposes to relate design, fabrication and construction through information networks (it is in fact a DT). Through the DCC approach, design information is becoming construction information and industrial fabrication information. The DCC has to integrate interaction design and respond to questions posed by DTs design. DTs are integrated to DCC by constituting an intermediate level between building programming and design. Intelligent Building Components, that is AmI components operating as bridges between the physical and the digital in Digital Territories formations, cooperating to develop swarm intelligence applications to architectural space, are elements managed by the DCC. DT’s are about spaces communicating and the DCC is about communicating (design) space.

title	Building Design Advisor: automated integration of multiple simulation tools
source	Automation in Construction 6 (4) (1997) pp. 341-352
summary	The Building Design Advisor (BDA) is a software environment that supports the integrated use of multiple analysis and visualization tools throughout the building design process, from the initial, conceptual and schematic phases to the detailed specification of building components and systems. Based on a comprehensive design theory, the BDA uses an object-oriented representation of the building and its context, and acts as a data manager and process controller to allow building designers to benefit from the capabilities of multiple tools.The BDA provides a graphical user interface that consists of two main elements: the Building Browser and the Decision Desktop. The Browser allows building designers to quickly navigate through the multitude of descriptive and performance parameters addressed by the analysis and visualization tools linked to the BDA. Through the Browser the user can edit the values of input parameters and select any number of input and/or output parameters for display in the Decision Desktop. The Desktop allows building designers to compare multiple design alternatives with respect to multiple descriptive and performance parameters addressed by the tools linked to the BDA.The BDA is implemented as a Windows®-based application for personal computers. Its initial version is linked to a Schematic Graphic Editor (SGE), which allows designers to quickly and easily specify the geometric characteristics of building components and systems. For every object created in the SGE, the BDA activates a Default Value Selector (DVS) mechanism that selects `smart' default values from a Prototypes Database for all non-geometric parameters required as input to the analysis and visualization tools linked to the BDA. In addition to the SGE that is an integral part of its user interface, the initial version of the BDA is linked to a daylight analysis tool, an energy analysis tool, and a multimedia, Web-based Case Studies Database (CSD). The next version of the BDA will be linked to additional analysis tools, such as the DOE-2 (thermal, energy and energy cost) and RADIANCE (day/lighting and rendering) computer programs. Plans for the future include the development of links to cost estimating and environmental impact modules, building rating systems, CAD software and electronic product catalogs.

title	The Role of Computers in the Building Life Cycle - What Computers Can and Cannot Do
doi	https://doi.org/10.52842/conf.caadria.2003.905
source	CAADRIA 2003 [Proceedings of the 8th International Conference on Computer Aided Architectural Design Research in Asia / ISBN 974-9584-13-9] Bangkok Thailand 18-20 October 2003, pp. 905-918
summary	The objective of this paper is to provide a conceptual framework that facilitates the development of integrated software environments that address the data and process needs of all building-related disciplines through the whole buil ding life cycle. The conceptual framework is based on a comprehensive analysis of the data and processes involved in d ecision-making, which is the common abstraction of all disciplines throughout the building life cycle. The role of computers is examined in every step of the decision-making process and through the building life cycle, focusing on what computers can and cannot do. The capabilities of computers are the used to present a vision for what the future of building design, construction and operation may be. While the vision is based on technologies that are already available, its realization requires significant research and development efforts. Conceptual, technical and strategic challenges to realizing the vision are presented and discussed.

title	Desktop Radiance A New Tool for Computer-Aided Daylighting Design
doi	https://doi.org/10.52842/conf.acadia.2000.009
source	ACADIA Quarterly, vol. 19, no. 2, pp. 9-11
summary	The use of daylight for the illumination of building interiors has the potential to enhance the quality of the environment while providing opportunities to save energy by replacing or supplementing electric lighting. Moreover, it has the potential to reduce heating and cooling loads, which offer additional energy saving opportunities, as well as reductions in HVAC equipment sizing and cost. All of these benefits, however, assume proper use of daylighting strategies and technologies, whose performance depends on the context of their application. On the other hand, improper use can have significant negative effects on both comfort and energy requirements, such as increased glare and cooling loads. To ensure proper use, designers need tools that model the dynamic nature of daylight and accurately predict performance with respect to a multitude of performance criteria, extending beyond comfort and energy to include aesthetics, cost, security, safety, etc.

title	Bridging the Gap Between Building Science and Designing Studios
doi	https://doi.org/10.52842/conf.caadria.2002.123
source	CAADRIA 2002 [Proceedings of the 7th International Conference on Computer Aided Architectural Design Research in Asia / ISBN 983-2473-42-X] Cyberjaya (Malaysia) 18–20 April 2002, pp. 123-130
summary	Design studios and building science courses have been conducted independent of each other, mainly due to a lack of tools that allow quick and easy consideration of building science criteria, such as comfort and energy requirements, during the design process. Existing tools are not user-friendly and their use requires significant effort in gaining familiarity with the input requirements, understanding the modeling assumptions and interpreting the output. This paper is about the Building Design Advisor (BDA), an evolving computer-based tool intended to bridge the gap between design studios and building science considerations by addressing the above-mentioned limitations of existing tools. BDA allows automatic preparation of input files to multiple simulation tools while the user is working in a CAD environment. BDA automatically activates the relevant simulation tools when the user selects performance parameters to be computed and provides the results in a graphical form, allowing comparison of multiple design options with respect to multiple performance criteria. The paper includes considerations for the use of the BDA in the design studio and ends with a description of the current development efforts and future plans.

title	Programming Twist - Exploring the geometric affordances of aluminum through flexible robotic workflows
doi	https://doi.org/10.52842/conf.ecaade.2022.2.399

summary	This paper explores the geometric affordances of aluminium through flexible robotic workflows. The geometric abundance of the discussed workflows goes beyond what the state-of-the-art industrial metal forming processes offer, and is achieved with simpler means. Two fabrication methodologies, folding and pressing, were explored in order to convert flat, straight panels into twisted, 3-dimensional shapes. The design method for both fabrication strategies was based on physics simulation, where several geometrical constraints force a real time deformation while maintaining the properties of a developable strip. In the first fabrication approach, directionality of the rulings is first engraved into the material while the folding angle is controlled by the robotic setup with two gripping stations. The second fabrication approach refers to a forming process. This has been achieved by installing a wheel cutter on a small workshop hydraulic press and a robot feeding the material into the forming station. The design-to-production pipelines are automated and designed for a small payload robot that allows for a large variety of geometric possibilities. Fabrication challenges of both processes have been documented and assessed, while workflow optimization scenarios and future improvements are proposed in the outlook.

summary	Fake.space is an elective CAAD course in which teachers and students form an online community. It is a Web-based communication environment for the exchange of ideas on the concept of space. Fake.space is also a narrative structure consisting of threads of nodes created by students. These nodes present different aspects of space. Fake.space represents our current generation of teaching environments. In this paper we describe and analyse its latest incarnation and discuss our aims and thoughts for further development. We believe that fake.space reflects on a future where online environments entice the students in a playful way to work with computers and CAD and consider the role of networked environments in architectural space.

title	Digital Fabrication Production System Theory: Towards an Integrated Environment for Design and Production of Assemblies
source	SIGraDi 2008 - [Proceedings of the 12th Iberoamerican Congress of Digital Graphics] La Habana - Cuba 1-5 December 2008
summary	A Digital Fabrication Production System (DFPS) is a concept describing a set of processes, tools, and resources that will be able to produce an artifact according to a design, fast, cheap, and easy, independently of location. A DFPS project is a complex assembly of custom parts that is delivered by a network of fabrication and assembly processes. This network is called the value chain. The workflow concept of a DFPS is the following: begin design process with a custom geometric form; decompose it into constructible parts; send the part files for fabrication to various locations; transport all parts at the construction site at the right time; finally, assemble the final artifact. Conceptually it means that based on a well structured value chain we could build anything we want, at anyplace, at controllable cost and quality. The goals of a DFPS are the following: custom shapes, controllable lead time, controllable quality, controllable cost, easiness of fabrication, and easiness of assembly. Simply stated this means to build any form, anywhere, accurately, cheap, fast, and easy. Unfortunately, the reality with current Digital Fabrication (DF) projects is rather disappointing: They take more time than what was planned, they get more expensive than what was expected, they involve great risk and uncertainty, and finally they are too complex to plan, understand, and manage. Moreover, most of these problems are discovered during production when it is already late for correction. However, there is currently no systematic approach to evaluate difficulty of production of DF projects in Architecture. Most of current risk assessment methods are based on experience gathered from previous similar cases. But it is the premise of mass customization that projects can be radically different. Assembly incompatibilities are currently addressed by building physical mockups. But physical mockups cause a significant loss in both time and cost. All these problems suggest that an introduction of a DFPS for mass customization in architecture needs first an integrated theory of assembly and management control. Evaluating feasibility of a DF project has two main problems: first, how to evaluate assemblability of the design; second, how to evaluate performance of the value chain. Assemblability is a system’s structure problem, while performance is a system’s dynamics problem. Structure of systems has been studied in the field of Systems Engineering by Network Analysis methods such as the Design Structure Matrix (DSM) (Steward 1981), and the liaison graph (Whitney 2004), while dynamics of systems have been studied by System Dynamics (Forrester 1961). Can we define a formal method to evaluate the difficulty of production of an artifact if we know the artifact’s design and the production system’s structure? This paper formulates Attribute Process Methodology (APM); a method for assessing feasibility of a DFPS project that combines Network Analysis to evaluate assemblability of the design with System Dynamics to evaluate performance of the value chain.

title	Understanding Behavior of Self - Organizing Vehicle Sharing Systems
source	SIGraDi 2010_Proceedings of the 14th Congress of the Iberoamerican Society of Digital Graphics, pp. Bogotá, Colombia, November 17-19, 2010, pp. 392-395
summary	Mobility on Demand (MoD) is a self - organizing one - way vehicle sharing system that allows users to pick - up from and drop - off to at station. MoD uses sensors to understand fleet distribution asymmetry and price incentives to motivate users to drive vehicles to stations that need the them most thereby increasing service performance. This paper presents current work done at the Smart Cities group of the MIT Media Lab for understanding decision - making in dynamically priced vehicle sharing systems, and exploring the circumstances under which such systems can become stable, sustainable, and profitable.

title	Computing and Visualizing Taxi Cab Dynamics as Proxies for Autonomous Mobility on Demand Systems. The Case of the Chicago Taxi Cab System

summary	Despite the expansion of shared mobility-on-demand (MoD) systems as sustainable modes of urban transport, a growing debate among planners and urban scientists regarding what constitutes cost and how to compute it, divides opinions on the benefits that autonomous MoD systems may bring. We present a comprehensive definition of cost of traveling by MoD systems as the cost of the vehicle hours (VH), the vehicle-hours-traveled (VHT), the vehicle-hours-dispatched (VHD), and the vehicle-hours-parked (VHP) required to serve a pattern of trips. Next, we discuss an approach to estimate empty (dispatch) trips and idle periods from a user trip dataset. Finally, we model, compute, and visualize the relationship between the dynamics of VHP, VHT, and VHD using Chicago’s taxi cab system as a case. Our results show that the total fleet of taxis in Chicago can decrease by 51% if all trips, currently served by conventional taxis, were served by autonomous ones.

title	Respace: A virtual environment for rethinking about space
doi	https://doi.org/10.52842/conf.caadria.2001.391

summary	ReSpace is a teaching module, which entices students in a playful way to work with computers and motivates them to think more deeply about the abstract idea of space. The goal of ReSpace is to enhance the concept of space by augmenting its content with additional levels of information like statements about emotions, by referring to senses, delineating impressions or telling stories and inducing memories. ReSpace takes advantage of the possibilities offered by virtual environments in the transfer of information and suggests space as a metaphor for the communication of ideas, knowledge and experiences about space. In this paper the module ReSpace taught by the author is described. Its central theme is the representation and communication of oneís notion, perception, and interpretation of space with the help of a 3D, interactive, virtual, environment. http://alterego.arch.ethz.ch
