title	A Web-based Virtual Lighting Simulator
source	Thresholds - Design, Research, Education and Practice, in the Space Between the Physical and the Virtual [Proceedings of the 2002 Annual Conference of the Association for Computer Aided Design In Architecture / ISBN 1-880250-11-X] Pomona (California) 24-27 October 2002, pp. 269-277
doi	https://doi.org/10.52842/conf.acadia.2002.269
summary	This paper is about a web-based “virtual lighting simulator” that is intended to allow architects andlighting designers to quickly assess the effect of key parameters on the daylighting and lightingperformance in various space types. The virtual lighting simulator consists of a web-based interfacethat allows navigation through a large database of images and data, which were generated throughparametric lighting simulations. In its current form, the virtual lighting simulator has two main modules,one for daylighting and one for electric lighting.The daylighting module includes images and data for a small office space, varying most key daylightingparameters such as window size and orientation, glazing type, surface reflectance, sky conditions, andtime of the year. The electric lighting module includes images and data for five space types (classroom,small office, large open office, warehouse and small retail), varying key lighting parameters such as theelectric lighting system, surface reflectance, and dimming/switching.The computed images include perspectives and plans and are displayed in various formats to supportqualitative as well as quantitative assessment. The quantitative information is in the form of iso-contourlines superimposed on the images, as well as false color images and statistical information on workplane illuminance. The qualitative information includes images that are adjusted to account for thesensitivity and adaptation of the human eye. The paper also contains a section on the major technicalissues and their resolution.

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	An Expandable Software Model for Collaborative Decision-Making During the Whole Building Life Cycle
source	Eternity, Infinity and Virtuality in Architecture [Proceedings of the 22nd Annual Conference of the Association for Computer-Aided Design in Architecture / 1-880250-09-8] Washington D.C. 19-22 October 2000, pp. 19-28

summary	Decisions throughout the life cycle of a building, from design through construction and commissioning to operation and demolition, require the involvement of multiple interested parties (e.g., architects, engineers, owners, occupants and facility managers). The performance of alternative designs and courses of action must be assessed with respect to multiple performance criteria, such as comfort, aesthetics, energy, cost and environmental impact. Several stand-alone computer tools are currently available that address specific performance issues during various stages of a building’s life cycle. Some of these tools support collaboration by providing means for synchronous and asynchronous communications, performance simulations, and monitoring of a variety of performance parameters involved in decisions about a building during building operation. However, these tools are not linked in any way, so significant work is required to maintain and distribute information to all parties. In this paper we describe a software model that provides the data management and process control required for collaborative decision-making throughout a building’s life cycle. The requirements for the model are delineated addressing data and process needs for decision making at different stages of a building’s life cycle. The software model meets these requirements and allows addition of any number of processes and support databases over time. What makes the model infinitely expandable is that it is a very generic conceptualization (or abstraction) of processes as relations among data. The software model supports multiple concurrent users, and facilitates discussion and debate leading to decision-making. The software allows users to define rules and functions for automating tasks and alerting all participants to issues that need attention. It supports management of simulated as well as real data and continuously generates information useful for improving performance prediction and understanding of the effects of proposed technologies and strategies.

title	The Role of Computers in the Building Life Cycle - What Computers Can and Cannot Do
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
doi	https://doi.org/10.52842/conf.caadria.2003.905
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
source	ACADIA Quarterly, vol. 19, no. 2, pp. 9-11
doi	https://doi.org/10.52842/conf.acadia.2000.009
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
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
doi	https://doi.org/10.52842/conf.caadria.2002.123
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.

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	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	Embedding sustainable storm water management in urban blocks - Towards an Urban Water Model for architects
source	Sousa, JP, Xavier, JP and Castro Henriques, G (eds.), Architecture in the Age of the 4th Industrial Revolution - Proceedings of the 37th eCAADe and 23rd SIGraDi Conference - Volume 2, University of Porto, Porto, Portugal, 11-13 September 2019, pp. 575-582
doi	https://doi.org/10.52842/conf.ecaade.2019.2.575
summary	The paper describes an urban storm water management model under development designed specifically for architects, allowing the visualization of storm water management scenarios in urban blocks, as well as the quantitative comparison of their impact to the microclimate. It seeks to answer the question of how computational technologies can help architects integrate storm water management into the design process and engage with water sensitive design principles through the development of an "architect-friendly" model. The model is expected to function as a simulation tool that will support design decisions on storm water management retrofitting measures in urban blocks, by allowing the evaluation of an urban water improvement project at its initial design stage, as well as the generation and comparison of alternate water integration design solutions. Selected urban blocks in Greece will be used as case studies to test and evaluate the urban water model during the model development stage.

title	Environmental Impact Assessment and Visualization of Rain-Water Best Management Practices for Urban Blocks - An "architect-friendly" simulation model
source	Pak, B, Wurzer, G and Stouffs, R (eds.), Co-creating the Future: Inclusion in and through Design - Proceedings of the 40th Conference on Education and Research in Computer Aided Architectural Design in Europe (eCAADe 2022) - Volume 2, Ghent, 13-16 September 2022, pp. 75–82
doi	https://doi.org/10.52842/conf.ecaade.2022.2.075
summary	In order to implement stormwater best management practices (BMPs) in urban blocks in Greece and other cities with warm and dry climates, such as green roofs, porous pavements etc., it is crucial that architects are able to assess their environmental impact during the design process in an efficient and simple way, without the requirement of an in depth understanding of the complex hydrological processes. To achieve the above, an “architect-friendly” computer-based model, under development by the authors, is presented. The model can be used as a decision support tool by allowing an assessment of the efficacy of non-conventional, water-sensitive, stormwater management strategies in an urban environment, measured by the stormwater runoff mitigation and temperature decrease. Wind flow simulation data from an external CFD model can be integrated into the proposed model, in order to visualize wind flow patterns in selected urban blocks. The user is able to select different stormwater BMPs from a BMP library and apply them on the 3D urban block model, in order to achieve an improved “water sensitive” state. The ENVI-MET plugin for Rhino is used for simulating temperature decrease and the SCS Curve Number method for determining stormwater runoff reduction, caused by each BMP application. The visualization of the results in the graphical interface of the Grasshopper programming environment facilitates the study of the environmental impact of stormwater BMPs in urban blocks and the comparison of different stormwater management scenarios. Several urban blocks in Athens will be used as case studies to test the proposed model and assess the efficiency of the visualization process.

title	A Simulation Model for Stormwater Runoff Management in Urban Blocks

doi	https://doi.org/10.52842/conf.ecaade.2023.2.287
summary	The shift towards Water Sensitive Urban Design (WSUD) has become a necessity for many cities with warm and dry climates which are still using conventional rainwater management and are adversely affected by extreme rainfall episodes or persistent heatwaves. However, WSUD still remains a complex issue for architects that requires specialized technical knowledge, relevant experience, and interdisciplinary collaboration. The paper presents initial results of an “architect friendly” computer-based model, developed by the authors, that facilitates the assessment of the efficacy of non-conventional, water-sensitive, stormwater management strategies in urban blocks, measured by the stormwater runoff mitigation. The model allows for the design and visualization of stormwater management scenarios on surfaces of selected urban blocks, as well as the quantitative comparison of their impact on runoff reduction. Users can choose from a range of different Best Management Practices (BMPs) from the BMP library of the model, create their own stormwater management scenarios, assess them, and finally choose the most appropriate one with regard to its impact on stormwater runoff. BMPs added in the library include green roofs with different substrate depths and plant types, facades, stormwater harvesting cisterns, raingardens and permeable paving. The Grasshopper programming environment has been used for the development of the model, the integration of as-built climate data and the incorporation of runoff estimation equations based on the Soil Conservation Service Curve Number (SCS-CN) method. The paper compares the results of different stormwater management scenarios that involve several BMP types and geometries, applied on an urban block in Athens, Greece. Based on this case study results, preliminary conclusions are drawn regarding the user-friendliness of the model’s interface and data requirements, as well as the effectiveness of the model’s visualization process.

doi	https://doi.org/10.52842/conf.ecaade.2024.2.089
summary	This paper introduces MARSH (Model for Assessment of Runoff and Stormwater Harvesting), an architect-friendly urban water model designed for 3D stormwater scenario assessments, integrating Water Sensitive Urban Design (WSUD) principles into architectural practice. Developed in the context of a funded research project UBWARMM (Urban Best Management Practices Model for Rainwater Management) and implemented in Grasshopper, MARSH serves as a comprehensive 3D toolkit for architects to evaluate stormwater scenarios effectively. The purpose of the model is to facilitate sustainable stormwater management and therefore runoff mitigation, and rainwater harvesting enhancement. Key components, including the Time Period Precipitation Calculator, Incident Radiation Analyses, BMP Library, Rainwater Harvesting Cistern Component, Roof/Inner Block Void Runoff Calculator, and Runoff Visualization, contribute to MARSH's robust structure. The conceptualization outlines precise data requirements, incorporating historical climate data and geometry datasets. Assessing Best Management Practices (BMPs) performance, MARSH delivers both numerical outputs (irrigation percentages, runoff reduction) and visual representations. MARSH's objectives encompass simplified processes, light data entry, accurate simulation, flexibility, a user-friendly interface, and result visualization. The research explores estimation methods, utilizing the Penman-Monteith equation for BMPs irrigation demands and the Soil Conservation Service Curve Number (SCS-CN) method for runoff estimation, addressing challenges related to runoff control and irrigation considerations. The model's adaptability, user-friendly interface, and visualization tools facilitate informed decision-making, in regions where WSUD integration is of critical importance. Validation through a case study in Athens provides insights for future studies, showcasing adaptability to different timeframes and scalability for city-scale applications. The potential of MARSH for both micro and macro-level stormwater management applications is also discussed in the paper.

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

summary	This paper presents an evolutionary algorithm that draws its power from the literal interpretation of the natural system’s reproductive process at a microscopic scale with the scope of generating optimal Delaunay triangulated space frames for dynamic loads. The algorithm repositions a firm number of nodes within a space envelope, by establishing Delaunay tetrahedra and, consequently, creating adaptable optimised space frame topologies. The arbitrarily generated tetrahedralised structure is compared against a canonical designed one and the results of this comparison indicate that the method proposed has advantageous properties and is capable of generating an optimum structure that exceeds statically the performance of an engineered tetrahedralised space frame.

summary	Previous research dealt with the problem of successfully approaching the combination of multiple, marginally compatible, historical and other forms of digital abstract data. The initial challenge, from a designer’s point of view, was to define and create the database for the Museum of the City of Volos (MuCiV) that will contain these seemingly incompatible data to a formulation collaborated with a geo-referenced information visualization system. This paper aims to go a step further by defining and implementing such an information visualization system. Thus, visual structures digitally representing a variety of non-spatial data, as well as the ways that these structures can interact, are investigated. It is argued that the results of this research can have interesting implementations to the museum program; by organizing in alternative ways its content and context and by facilitating the dissemination of information to the public through interactive multimodal exhibits.

summary	It is widely accepted that cities cultivate innovation and are the engines of productivity. The identification of strengths and weaknesses will enchant social mobility providing equal opportunities for all. The study at hand investigates the relationship between social mobility and transportation planning in 1,860 central urban areas across the globe. Datamining processes combining open-sourced, automated, and crowdsourced information from four major pillars of social mobility (demographics, human activity, transport infrastructure, and environmental quality) are used to describe each location. Next, unsupervised clustering algorithms are used to analyse the extracted information, in order to identify similar characteristics and patterns among urban areas. The process, which comprises an objective framework for the analysis of urban environments, resulted in four major types of central areas, that represent similar patterns of human activity and transport infrastructure.

summary	Recent advances in Machine Learning and Deep Learning revolutionise many industry disciplines and underpin new ways of problem-solving. This paradigm shift hasn't left Architecture unaffected. To investigate the impact on architectural design, this study utilises two approaches. First, a text mining method for content analysis is employed, to perform a robust review of the field's literature. This allows identifying and discussing current trends and possible future directions of this research domain in a systematic manner. Second, a Scientometrics study based on bibliometric reviews is employed to obtain quantitative measures of the global research activity in the described domain. Insights on research trends and identification of the most influential networks in this dataset were acquired by analysing terms co-occurrence, scientific collaborations, geographic distribution, and co-citation analysis. The paper concludes with a discussion on the limitations, opportunities and future research directions in the field of Machine Learning-aided architectural design.

title	Digital space and ephemeral visuals as determinants of contemporary design: A Survey of Projects of Architectural Students in CAAD

summary	Outside of views produced deliberately for the design of architecture, there exists a large body of images; visuals of no materialized spaces, constructed only on paper or in pixels in popular cultural media – editorial illustration, comic strips and books, cinema, television, advertising and web imagery. All the aforementioned visuals, fragments of architecture are within our everyday life and more important influence strong spatial paradigms for students of architecture. The proposed presentation is about the work within a university Computer Aided Architectural Design studio where students asked to investigate the ephemeral environments that surround their everyday life and translate them into architectural intentions. This paper argues that the digitally mediated design of young students of architecture incorporates the ubiquity of contemporary life-style; reflects through student design proposals the new orientations of contemporary architecture and finally revises the integration of the CAAD studio with the ‘traditional’ studios of design within the school of Architecture.
