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.

September, 2017, Vienna

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.

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.

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.

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.

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.

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.

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.

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.

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. .

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.

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.

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.
