Abstract.

Writing academic papers is challenging, and formatting them can be even more time-consuming. Over time, the demands for multi-stage submission and review processes have gradually increased. At the same time, the number of submissions and published conference papers has steadily grown. In contrast to journal papers, there is a clear drive to complete this process just in time for the conference itself, which limits the number of feasible iterations. ProceeDings 1.0 introduced a simple but effective workflow: plain text as input and LaTeX for PDF generation. This approach produced high-quality results, including robust equation rendering. However, LaTeX's automatic figure placement is often difficult to control, as images are positioned based on available space and may shift to later pages. This behavior contrasts with DTP-tools such as Adobe InDesign, which allow precise figure placement and flexible text flow. ProceeDings 2.0 addresses these limitations in a web-based environment. It uses browser-based rendering technologies, reducing the need for server-side resources while maintaining flexibility in layout control. This paper describes the system architecture and presents an initial analysis of papers created with the platform. The results provide insight into common structural patterns in CAAD publications. We also identify current limitations, discuss lessons learned during system deployment, and outline directions for future development.

Abstract.

Vienna holds an enormous, largely unmapped material stock — brick, wood and steel locked inside buildings that will eventually be demolished. To locate where similar recycling potential clusters, we partition the entire city into approximately 16,000 map tiles of roughly 200 m side length and task an artifi cial-intelligence workfl ow with assigning each tile one of fi ve characteristic Viennese building types. Experts (architects and urban planners) manually label only a small set of archetypal tiles; from these few examples, two automatic methods scale the classifi cation to the whole city: a hand-crafted vector-distance similarity and a supervised machine-learning classifi er based on decision trees and random forests. This contribution reports what the AI learned, how the two methods compare in accuracy, where the AI agrees with human experts, and — most revealingly — where and why it does not.

Abstract.

The students‘ conference “Algorithms in Planning Practice 2026” is the result of a seminar held at the Research Unit Digital Architecture and Planning at the TU Wien in the summer semester 2026. The contributions deal with current algorithms and data structures that are relevant for the planning of complex buildings such as hospitals, airports or train stations. The papers cover methods such as bin packing, genetic algorithms, kd-trees, and other partitioning of space, box counting, viewshed analysis and graph-based functional analysis.The conference proceedings provide an up-to-date overview of the current state of research and show examples of how algorithmic thinking can solve planning-relevant problems and how it is expanding the architectural and functional design process.

Urban Transformation Between Built and NaturalSystems by Means of an Adapted Wave FunctionCollapse Approach

June, 2026

Abstract.

In practice, urban transformation is often carried out at the outskirts or in between existing areas of a city. In that context, important questions are: How can one imagine a transition between different urban structures? What if, additionally, we aim for including not only the development from innermost to outermost but also vice versa-letting nature into the city rather than the other way around? What are the implications of interventions on the surroundings? Addressing these questions requires a modelling approach that links local morphological compatibility between urban structures with macro-scale socioeconomic feedback driving development, vacancy and ecological change. To that end, we combine complementary modelling components. A cellular-automaton (CA) grid provides the spatial representation and hosts rule-based land-use transitions over time. Within this structure, an adapted Wave Function Collapse (WFC) operator infers context-sensitive land-use changes from learned adja-cency relations, ensuring morphological compatibility of infill and transformation. A system-dynamics (SD) layer generates macro-scale pressures in households, jobs and capital that drive development, vacancy and decline across the grid. Evolution over time emerges from the CA rule system and from vacancy-driven transformations derived from previous work on urban cell grammars, extending WFC from a static pattern generator to a dynamic operator of urban change. Our framework is intended for use in planning, but also in education and policy making ("What-If"-Scenarios). The system supports both conventional development trajectories and their inversion: not only densification and infill, but also decline, abandonment, and ecological succession where nature re-enters under conditions of sustained vacancy.

Abstract.

This presentation explores process-driven approaches to healthcare design through early-stage functional planning and agent-based simulation. Instead of beginning with architectural form, the presented methods derive spatial organization from activities, functional relationships, and treatment processes. Using schematic models, treatment chains, and real process data, simulation enables the analysis of patient flows, resource utilization, bottlenecks, and spatial demand already in the early design stages. The talk further discusses how complex system behavior emerges from interactions between patients, staff, and functional units, and how such approaches can support the planning of other complex building types beyond healthcare.

Abstract.

This presentation explores how municipal data provided by the City of Vienna can be used to support urban analysis, planning, and decision-making. Using examples from current research projects, it demonstrates how spatial data, 3D city models, GIS workflows, and machine learning methods can be combined to investigate topics such as zoning visualization, attic conversion potential, housing quality, and urban material stocks in the context of circular construction.

Abstract.

In the context of Urban Mining, it is essential to know the material composition of the building stock. In our project M-HUB (Data hub for the collection and viewing of material compositions of the building stock of the City of Vienna), we have thus worked on ways of learning material compositions from samples taken in buildings of various periods. We employ machine learning (e.g. random forests) to predict wall and floor compositions and use these in connection with the building footprint for extrapolation. As shown, our results closely match the ground truth (more than 80 percent accuracy, depending on building period). As a matter of fact, we can infer the material composition of the urban building stock even for buildings that have not been surveyed. Additionally, we also sample building elements (e.g. windows, doors) that can be reused or repurposed; we learn to predict the existence of such elements in the same fashion. As to the applicability of our data hub, we target real estate developers, municipalities and planners. The first ones need an estimation of how much material and what kind (contaminants!) one would incur in renovation and demolition; municipalities might be interested in the same information, but on an aggregate level. And lastly, architects might also want to incorporate “waste” material or elements into their design, so as to decrease their carbon footprint (e.g. by using old bricks, wooden beams or doors and windows).

Abstract.

Research-driven education (“Forschungsgeleitete Lehre“) is common throughout TU Wien, be it in the form of seminars, labs or lectures. As such, the course “Algorithms in Planning” (259.669 SE, 3 ECTS) was nothing special: We looked at recent papers, did some background research on the State of the Art in Algorithmic Planning and compiled these results into written reports (i.e. papers). However, in contrast to regular hand-ins we used a conference system and compiled a proceedings instead of letting the good work go to waste. We also organized a (student-led) conference instead of an end presentation, so this is indeed special and not something that happens regularly at our university.

Abstract.

Urban transformation is key to achieving more livable and sustainable cities. However, modelling this evolution is highly non-trivial since there are many factors at play that manifest themselves in the built (or: non-built/restored) environment. In our most recent work, we have represented urban change as rules of a three-dimensional Cellular Automaton. With these rules we represent a variety of retrofitting options - additive (e.g. densification through roof extensions, facade greening, installation of solar panels) or subtractive (e.g. soil descaling), that lead to urban change as an emergent outcome. The editing of rules is embedded into a web-based visualization which acts as a test-bed and platform we have used in a design studio setting and can thus report on our lessons learned in that context.

Abstract.

In the context of the design studio "Kindergarten meets Easy Rider", new and innovative ways of building kindergartens were examined. In more detail, we took the biking milieu with its demand for freedom and individualism as a starting point for rethinking kindergarten design. Quite stunningly, this strive for freedom and individualism is also important for the building clients (i.e. children), and more unexpected similarities such as group formation through inclusion and exclusion and a constant urge to “move” were found. In an architectural context of a kindergarten, this leads to new approaches on circulation and room disposition, which we want to report on using two case studies in this paper. For both approaches, generative algorithms were developed to support the design process.

Abstract.

M-DAB2 aims at localization, quantification, and qualification of inner development potentials and shall, for the first time, account for material intensities in inner development (amount of primary material) in the context of different development scenarios. Building on the extended data basis of the previous project M-DAB (FFG No. 873569), this project elaborates on potential profiles of different building and location types according to several parameters (e.g. building period, usage, construction class). The information for determining the profiles (but also of location qualities) comes from the GIS data of Vienna. All data are aggregated on the cells of a grid, where the cell size is determined by the zoom level 17. On this basis, similarities between cells in the city are then searched for. Further location qualities are used to restrict the selection.

Abstract.

This paper describes the concept of integrating several complexity evaluation methods, previously developed and tested by the authors, into one product configurator through a technical prototype. In this case variations of an online configurator for design products based on a choice of these digital complexity evaluation methods developed between 2015 and 2020 are presented.

This research shows that an integration of complexity evaluation for several Gestalt qualities in one product configurator is feasible, though the amount of aspects of each of these qualities and the necessary effort to be invested to achieve an integration that is suitable for customer use may vary. The concept is illustrated using a simple test case, i.e. an online shelf configurator.

Abstract.

In most cities, cars remain the dominant mode of transport. This is a huge problem not only because of obvious effects such as congestion and pollution, but also because it causes health issues for commuters themselves which lead to further costs for the community. In our work, we have developed an agent-based simulation which offers mitigation strategies and tries to propose realistic lines of action for transport modes to more sustainable modes. Our approach can import from GIS or (raster) maps, thus acting as a planning tool for urban planners and city administrators; we also included the possibility for generating theoretical / idealized cities, as a testbed and theoretical tool for instructing policy makers. Our goal is to find an equilibrium between individual freedom in transport choice, financial effort required for maintaining the overall transport system and the health of the whole population.

abstract: The design studio "designing a dynamic hospital for pandemics" took place in the winter term 2020/2021 at TU Wien, during the 2nd wave of the SARS-CoV-2 pandemic. Its goal was to establish novel ways in which hospital architecture can react to a pandemic crisis, mostly in a permanent (built) manner rather than by using temporary measures. As such, the subject was unprecedented in TU Wien's curriculum. New ways of working together had to be established, since TU Wien was closed (everyone worked from the home office) and we did thus not have the usual physical desk crits but rather only ZOOM calls. As a matter of fact, we shifted the medium from presentations, drawings and models to papers, which we thought would give more structure to each and every students' contribution. The outcome is to be found in this collection of working papers.

Abstract.

European cities like Vienna are characterized by strong growth and, as a result, by high demand for living space. Extending the attic is one way of meeting this demand. However, there is a lack of data to know which roofs are already expanded and to what extent. The city is interested in the data in two ways: firstly, in relation to the distribution of potentials (a possible change in population density, for example, has an impact on infrastructure and parking space) and, secondly, in relation to the material composition (city as a material resource). This paper provides a workflow to fill this gap of knowledge. The new methods of detecting attic extensions are described and a case study is given at the end to show workability.

Abstract.

The prediction of microclimate effects within an urban context through simulations has previously been done through elaborate software packages that offer accurate results but require extensive domain knowledge and time for the preparation of a model. In day-to-day policymaking, however, these efforts may turn out to be a major limiting factor: Policymakers and city administrators need a quick tool that can predict the effects of urban interventions in a variety of possible scenarios rather than a full-fledged simulation study for a limited set of specific interventions. In our work, we have been seeking to address this mismatch in expectations by using the best of both worlds: We have approximated results from a full-fledged simulation that uses a Cellular Automaton running within a 3D city visualization. Policymakers can edit the urban context by changing cell types (placement of greenery, etc.), thus leading to scenarios that can be compared to the status quo. As a matter of fact, policymakers can use these comparisons to argue for measures that mitigate the effects of heat islands, without requiring extensive domain knowledge or the effort to prepare a simulation model.

Abstract.

If we strive for a de-carbonized future, we need to think of buildings within a city as resources that can be re-used rather than being disposed of. Together with considerations on refurbishment options and future building materials, this gives a decision field for stakeholders which depends on the current "building stock" - the set of pre-existing buildings which are characterized e.g. by building period, location and material composition. Changes in that context are hard to argue for since (1.) some depend on statistics, other (2.) on the concrete neighborhood and thus the space in which buildings are embedded, yet again others on (3.) future extrapolations again dealing with both of the aforementioned environments. To date, there exists no tool that can handle this back-and-forth between different abstraction levels and horizons in time; nor is it possible to pursue such an endeavor without a proper framework. Which is why the authors of this paper are aiming to provide one, giving a model of change in the context of re-using material resource of the city, when faced with numerous abstraction levels (spatial or abstract; past, current or future) which have feedback loops between them. The paper focuses on a concrete case study in the city of Vienna, however, chances are high that this will apply to every other building stock throughout the world if enough data is available. As a matter of fact, this approach will ensure that argumentation can happen on multiple levels (spatial, statistical, past, now and future) but keeps its focus on making the building stock of a city a resource for sustainable development.

Abstract.

The rezoning process primarily deals with proposed changes on land-use and zoning plans. More and more often, the public is asked for its opinion and feedback. However, there are two main obstacles in today´s practice: On the one hand land-use and zoning plans, in general, only define the potential of areas and so do proposed draft plans; they usually say nothing about the implementation of land-use in the built space. On the other hand, the untrained majority can hardly grasp the current form of representation as two dimensional plans with accompanying written information. In order to enable a wider public participation (and understanding), the authors present FLÄVIZ, a 3D visualization of potentials on land-use and zoning plans.

Abstract.

This paper is based on the assumption that a key challenge of good design is spatial organisation as a result of functional requirements. The authors present a new NetLogo application that assists designers to understand the proposed functional relationships (of spaces) by visualizing them graphically. In more detail, the tool translates adjacency matrices as representation of functional relationships into a graph (in architecture known as bubble diagram). The latter can be considered as a pre-step of the actual design, by which the information about functional interrelations becomes more readable and understandable for the designer.

Abstract.

Hospital refurbishments often take place in parallel to regular operation, resulting in a scheduling problem: Construction activities must be located such as they do not clash with daily work activities and vice versa. To be able to see this mutual influence, we have devised a tool in which we are able to visualize the adverse effects of construction on daily operation. The approach uses a cellular automaton to represent the three-dimensional hospital environment and uses a particle simulation for computing the distribution of dust, noise and vibrations. By interactively relocating work activities and construction activities, our tool can be used to solve the mentioned scheduling problem. It also enables us to show the sequence of construction and relocation activities in 3D, which might be easier to interpret than a classical project plan in tabular form.

Abstract.

This work explores the dichotomy between old areas offering high-quality living in a low-density neighborhood (typically near the city center) and newly-developed areas with high-density and lesser quality in the suburbs. It especially addresses the scarcity of rentable `Gründerzeit' flats in Vienna/Austria which have a ceiling height of 3.40m and date back to the mid-19th century. Other European cities have the same problem - supply of old properties perceived as offering a high quality of living does not meet the demand, which leads to high rent prices. The authors have captured the current situation of the housing market using Cellular Automaton (CA) rules; their main contribution lies in the exploration of three additional rules that seek to improve the availability of old (i.e. `Gründerzeit') flats.

Abstract.

Shop Design ist das Produkt aus Marketing, wirtschaftlichem Kalkül, Kommunikation und der Gestaltung von Räumen. Marketinganalysen beeinflussen unter der Anwendung von Prinzipien der Verkaufspsychologie sowohl die Produktplatzierung, die Wegeführung als auch die Auswahl der Präsentationsmittel. Letztlich zielen aber alle Maßnahmen auf den Umsatz ab, um vor der stetig präsenten Konkurrenz bestehen zu können. Erst der wirtschaftliche Erfolg ist Garant für das Weiterbestehen. Unter dem Einfluss der Kalkulation entstehen Bausysteme die unterschiedlichen Anforderungen gerecht werden. Aus diesen Systemen lassen sich unter Berücksichtigung eines Leitsystems verschiedene Produktgruppen präsentieren und stellen das Einkaufen zwischen schneller Notwendigkeit und vergnüglicher Erholung dar. Im Mittelpunkt dieser Betrachtungen steht stetig die Kommunikation mit dem potenziellen Kunden. Im Zuge der Lehrveranstaltung wurden nun die für das Shop Design entscheidenden Einflussfaktoren analysiert, um daraus neue gestalterische Anwendungsgebiete zu finden. Zur einfacheren Handhabung wurden algorithmische Lösungsmethoden angewandt. Diese bezogen sich nicht nur auf die Anwendung von Standardformaten (vorhandenes System), sondern auch auf eine mögliche neue gestalterische Formensprache (Entwicklung eines neuen Systems). Den Entwurfsprozess begleitete stetig die Frage in wie fern durch die Zerlegung in separat lösbare Teilbereiche neue Perspektiven eröffnet und mögliche Alternativen bereitgestellt werden können. Je nach Problemstellung änderte sich dabei der Einsatz des digitalen Werkzeugs. Zur Wegefindung und/oder Platzierung der Präsentationssysteme eignete sich etwa die agentenbasierte Simulation mit NetLogo.

Abstract.

The paper describes and discusses the possible integration of gradient analysis into the learning environment, as a tool to optimize design-objects in regards to their proportion-complexity. To create a responsive system to be used within a design- or learning process the gradient analysis has been integrated in an interactive genetic algorithm (IGA). Within the IGA it serves to determine the fitness value of a given object evaluating the degree of proportion complexity and to create variations with an optimized degree of proportion complexity.

Abstract.

This paper explores the differences between `design' and `science' papers published at eCAADe conferences through use of automatic classification. The latter is conducted using a set of differentiating criteria (e.g. number of figures determines a paper to be either `design' or `science') which are calibrated with the help of a manual selection of papers from eCAADe 2015 as ground truth. Results show that we predict 83% of the papers correctly; experiments using data from eCAADe 2014 until eCAADe 2016 furthermore show the stability of our results. However, we are not so much after the development this automatic classification but rather want to characterize the two research cultures of design and science. This is achieved by taking a close look at the differentiating criteria, which can inform tools such as ProceeDings over possible future directions and adaptation needs.

A Building Database for Simulations Requiring Schemata

May, 2017, Vienna

Abstract.

Obtaining spatial representations of existing buildings for use in simulation is challenging: To begin with, getting permission to access submitted construction plans can take a long time. Then these might only be available in analog form, making it necessary to scan and vectorize them at the regulations office. The resulting representation might still not be adequate for simulation, requiring further extraction of relevant features and enrichment by additional information in order to fit the simulation domain. In our work, we have specifically targeted simulation types that work with schemata (e.g. occupancy, work and egress simulations). Our contribution lies in restructuring the aforementioned workflow so as to (1.) minimize time and effort spent on digitizing and to (2.) automatically derive schemata – sets of boundary polygons which (3.) can be further enriched by attributes. These steps are embedded into a web-based building database which allows uploads and queries per web interface as well as web services. The query interface furthermore includes (4.) the ability to download the schemata both in vector as well as raster form so that they can be used for both discrete and continuousspace approaches. Apart from acting as data provider, the database furthermore (5.) allows for spatial predicate functions which may be used for analysis of a space program.

Coupling Building Morphology Optimization and Energy Efficicency - A Proof of Concept

Abstract.

This contribution focuses on recent efforts towards coupling building morphology optimization and energy efficiency computation in the context of early stage hospital planning. In more detail, a Netlogo model was conceived to generate typological design variations based on a grid grammar. Each resulting design was subjected to a fitness test based on a coupled energy performance model, which is unprecedented for early stage form finding to the best of our knowledge. However, given that hospitals require a large amount of energy for operation, energy efficiency considerations should indeed be implemented as early as possible within the design process. The given paper presents methodology and early results of these efforts.

Abstract.

The design studio 'Flying Bricks' was held during the summer semester 2015. Its main objective was to redesign an existing building with the use of facing bricks algorithmically, utilizing algorithmic thinking and programming as a means for form generation. The purpose of having students express their designs in terms of code was to emphasize problem thinking over solution generation, which has several advantages but also disadvantages which we would like to share in this paper. Furthermore, we would like to show how our implementation process worked, so that others can leverage that for their own algorithmic design courses.

Abstract.

In this paper, we have adopted methods from Social Network Analysis in order to analyze adjacency graphs. Our intent was to uncover as much hidden structures as possible so as to improve adjacency requirements before they are used further on during the design process. To that end, we have conducted a case study using two readily available software packages (Gephi, Pajek), concluding that these could benefit from being more transparent about the underlying algorithms and more geared towards the problem domain 'adjacency analysis' when it comes to data entry and visualization. As a matter of fact, we produced an open-source prototype called SpaceBook, which customizes computation and visualization in the aforementioned spirit.

Utilizing Gradient Analysis within Interactive Genetic Algorithms

Abstract.

The paper describes and discusses the possible integration of gradient analysis, as a method and tool for architects and designers to analyze the degree of proportion-complexity of a design, into the process of designing an object utilizing interactive genetic algorithms (IGA). A VBA implementation for AutoCAD has been developed by the authors, enabling to test the usability of genetic algorithms (GA) for minimizing the angle-redundancy and length-redundancy quotient. The gradient analysis itself has been developed on the basic assumption that the complexity of an objects appearance is reduced by redundancy, which can be measured focussing on different levels of comparison; among others e. g. variety of material, colour-combinations and proportion. The latter comes under scrutiny if the method of gradient analysis is applied.

Towards Rating of Generated Typologies by Means of Adjacency Comparisons

May, 2016, Vienna

Abstract.

Applying different typologies to the same building yields a number of options concerning extensibility and circulation. However, it is hard to rate and compare these in order to find the most fitting one for a specific building task at hand. In this paper, we wish to work towards this goal using a showcase in which we generate and rate a large number of buildings in order to find out whether certain typologies prevail among the fittest solutions. On a technical level, we contribute (1.) a simple cell-space grammar that generates building volumes, given a preference for different axes in which form can develop - orthogonal, diagonal and vertical, (2.) a rating procedure which infers a fitness for every solution, based on (a.) the assignment of functions to parts of the generated building and computation of adjacencies between these and (b.) the extensibility of the building along its axes. Typologies are attributed in a post-step, as part of a manual analysis. Our results show a preference for the compact/central building type, as dictated by the use of adjacencies for rating a building.

Gradient-Analysis: Method and Software to Compare Different Degrees of Complexity in the Design of Architecture and Designobjects

September, 2015, Vienna

Abstract.

The aim of the research presented in this paper is to provide an additional method and tool for architects and designers as well as students and scholars to analyze the degree of complexity of a design. Fractal analysis (box counting) e.g. is one of these methods already used in architecture to measure the degree of complexity of an architectural design, for example of the elevation of a building. The method of semi-automated gradient-analysis described here focuses on the repetition of gradients and thus of proportion-repetition in a given design as one of several aspects of complexity reduction by redundancy.

Adjacency in hospital planning

February, 2015, Vienna

Abstract.

Adjacencies stand at the beginning of a multitude of planning tasks. Especially in hospital planning they are essential for describing relationships between different organizational units – e.g. ‘close’, ‘distant’ or ‘neutral’. Mathematically, these terms map to relative weights between each pair of units in the range [-1, 1] which are put into a (symmetric) adjacency matrix. This matrix subsequently determines relative locations of individual spaces (preliminary space layout). The paper deals with the effective definition of this adjacency matrix in the context of early-stage architectural planning. In contrast to current planning practice, which looks at each adjacency relation in isolation, our approach uses a Newtonian gravitation model to propagate changes to a single relationship immediately to the whole space layout. As a result, we are able to supply architects with a design tool that accelerates the definition of adjacencies and lets them preview the preliminary space layout at the same time.

MODYPLAN: Early-Stage Hospital Simulation based on Treatment Chains

February, 2015, Vienna

Abstract.

Discrete-event simulation of hospitals typically specifies flow by means of a process graph through which patients are routed. While this is generally fine for models in which processes are clearly defined, e.g. smaller units such as emergency departments, it falls short of capturing the fact that a patient can in principle go from one unit to any other unit if medical procedure requires it. This problem becomes even more evident when modeling a whole hospital, at which level specifying each individual treatment through directed edges and nodes becomes unviably complex. In the past three years, we have been developing a combined hospital simulation/space design tool in which processes are defined individually by patient, as sequence of visited units imported from the Hospital Information System (treatment chains). The major advantage of this approach lies in the fact that we can now design a future space layout in which assumed capacities (staffing, equipment, required space) can be tested against the recorded patient volume, using an Agent-Based Simulation to re-enact each treatment chain. In contrast to other hospital simulations, this approach targets early stages of architectural conception, during which the actual building structure is elaborated. Using the method, we can compare and contrast different layouts during that stage, making simulation a driver for design rather than a tool for late optimization within the final floor plan.

Causality in Hospital Simulation Based on Utilization Chains

Abstract.

The operation of complex buildings (e.g. airports, hospitals, industrial facilities, penitentiaries) is commonly simulated forward in time: Agents arrive and perform their prescribed tasks, utilizing resources and space as required. When trying to understand the model's state at a certain point in time, say, "why is this resource over-utilized", one must either guess or run the simulation again to determine what the cause is. Our contribution lies in the introduction of causal chains into the workflow of an agent-based simulation, so that an end user (in our case: process planner and hospital architect) can get a further insight into the intermediate simulation result at a certain point in time, without having to re-run it. .

From Quantities to Qualities in Early-Stage Hospital Simulation

Keywords: Fuzzy Logic, Hospital Simulation, Early-Stage Design.

September, 2013, Vienna

Abstract.

Simulation in early stages of hospital planning might not live up to its full potential: Results come as quantitative (crisp) values, whereas early conception specifies requirements in a more qualitative (think: linguistic) fashion. Because of this gap, it is no wonder when planners cannot easily interpret what is computed. In our most recent work, we have addressed this issue through fuzzy analysis: Crisp simulation results are mapped back into linguistic terms, which can then be compared to the requirements set by the planning team. On the one hand, this enables us to communicate “in the right language”, on the other hand, we may use this comparison for automatically raising warnings, in case there is a mismatch between the two.

Pre-Tender Hospital Simulation Using Naive Diagrams As Models

Abstract.

Hospital simulation has so-far concentrated on late phases of architectural planning, in which the design is already fully formulated and undergoes optimization. This paper moves into the exactly opposite direction - it tries to embed simulation into the earliest phase imaginable, which, interestingly, is well before any architectural planning occurs: The pre-tender work that is done by or on behalf of the client, using naïve diagrams based on interviews with the medical staff as models.

September, 2012, Vienna

Abstract.

During early-stage planning, numerous design decisions are taken in an argumentative manner, based on occupation with the building site according to the different infl uencing aspects (e.g. topology, wind, visibility, circulation, activities etc.). In this context, sketches, diagrams and spreadsheets are the workhorses for elaboration. However, some of these phenomena are dynamic by nature, and are rather poorly modeled when utilizing static media. In our work, we thus show how agent-based simulation can be used to compute and visualize dynamic factors, in order to inform the decision process on a qualitative level. As a matter of fact, simulations may be used as a design tool in their own right, for analysis and objectifi ed comparison among multiple design variations.

Abstract.

Computer programming in architecture seems to be commonplace throughout the eCAADe Community. Yet, a critical evaluation of a programming course as seen from a student’s side is still missing. During a week-long programming workshop in a fellow university, we have been assessing subjective parameters such as mood, quality of presentation and comprehensibility, comparing these to the actual topics that were covered at this instance. Our results contribute to understanding architecture students in their quest towards algorithmical thinking. We are convinced that the discussion given in this paper will help other teachers to further increase the quality of their lectures. Furthermore, the structure of our approach may serve as basis for further research into recording student behavior during programming courses.
