Wissenschaftliches Kolloquium vom 27. bis 30. Juni 1989 in Weimar an der Hochschule für Architektur und Bauwesen zum Thema: ‚Produktivkraftentwicklung und Umweltgestaltung. Sozialer und wissenschaftlich-technischer Fortschritt in ihren Auswirkungen auf Architektur und industrielle Formgestaltung in unserer Zeit. Zum 100. Geburtstag von Hannes Meyer'
For decades in Germany, historical research on dictatorial urban design in the first half of the 20th century focused on the National Socialist period. Studies on the urban design practices of other dictatorships remained an exception. This has changed. Meanwhile, the urban production practices of the Mussolini, Stalin, Salazar, Hitler and Franco dictatorships have become the subject of comprehensive research projects. Recently, a research group that studies dictatorial urban design in 20th century Europe has emerged at the Bauhaus-Institut für Geschichte und Theorie der Architektur und der Planung. The group is already able to refer to various research results.
Part of the research group’s self-conception is the assumption that the urban design practices of the named dictatorships can only be properly understood from a European perspective. The dictatorships influenced one another substantially. Furthermore, the specificities of the practices of each dictatorship can only be discerned if one can compare them to those of the other dictatorships. This approach requires strict adherence to the research methods of planning history and urban design theory. Meanwhile, these methods must be opened
to include those of general historical studies.
With this symposium, the research group aims to further qualify this European perspective. The aim is to pursue an inventory of the various national historiographies on the topic of “urban design and dictatorship”. This inventory should offer an overview on the general national level of historical research on urban design as well as on the level of particular urban design projects, persons or topics.
The symposium took place in Weimar, November 21-22, 2013. It was organized by Harald Bodenschatz, Piero Sassi and Max Welch Guerra and funded by the DAAD (German Academic Exchange Service).
Assessing Essential Qualities of Urban Space with Emotional and Visual Data Based on GIS Technique
(2016)
Finding a method to evaluate people’s emotional responses to urban spaces in a valid and objective way is fundamentally important for urban design practices and related policy making. Analysis of the essential qualities of urban space could be made both more effective and more accurate using innovative information techniques that have become available in the era of big data. This study introduces an integrated method based on geographical information systems (GIS) and an emotion-tracking technique to quantify the relationship between people’s emotional responses and urban space. This method can evaluate the degree to which people’s emotional responses are influenced by multiple urban characteristics such as building shapes and textures, isovist parameters, visual entropy, and visual fractals. The results indicate that urban spaces may influence people’s emotional responses through both spatial sequence arrangements and shifting scenario sequences. Emotional data were collected with body sensors and GPS devices. Spatial clustering was detected to target effective sampling locations; then, isovists were generated to extract building textures. Logistic regression and a receiver operating characteristic analysis were used to determine the key isovist parameters and the probabilities that they influenced people’s emotion. Finally, based on the results, we make some suggestions for design professionals in the field of urban space optimization.
This project proposes and applies a research strategy to understand types of cities using the case study of Bogotá. This strategy combines a conceptual framework developed around the notion of ‘centrality’ and ‘urban semiotics’ as a method of qualitative enquiry in order to comprehend complex spatial arrangements as significant constituents of cultural geographies. In this sense, this study problematizes current tendencies such as spatial fragmentation and challenges the argument that contemporary urban ensembles in Latin America are either homogenized within globalization trends or illegible entities with no structural coherence.
Bogotá is addressed as an instrumental case study to redraw generalizations developed from different methodological frameworks about the configuration process of spatial structures and their significance within the Latin American geography. Thus the study questions how urban centrality has evolved as an essential socio-cultural phenomenon and in this manner decodes the messages transmitted by main spatial arrangements. As a first step, the study discusses the construction of spatial meaning and its structural interpretation. In addition, the concept of centrality is examined in depth and an urban centrality typology is introduced to enable the analysis of spatial structures in socio-cultural terms. These contents are followed by the discussion of the existing approaches to the topic and their limitations. Subsequently, this research reconstructs the configuration of Bogotá’s spatial structure which is decoded in the last chapter.
The study concludes that the highly fragmented and uneven condition of urban space in Latin America can be read. The case study of Bogotá substantiates that there is a code that paradoxically provides spatial cohesiveness within unstable socio-spatial hierarchies. Such a spatial code is deciphered through the reading of Bogotá’s spatial structure whose super-centre denotes ‘the sacralisation of authoritarianism’. This is a ‘structural meaning’ related to a specific or intrinsic logic of spatial concentration that is useful for the further discussion of socio-spatial patterns and the meanings of Latin American cities. The concluding remarks integrate the main arguments and outline lines of action in spatial planning processes.
Die im Jahr 2020 in Deutschland praktizierte Siedlungs- und Wohnungspolitik erhält in Anbetracht ihrer Auswirkungen auf die soziale und ökologische Lage einen bitteren Beigeschmack. Arm und Reich triften weiter auseinander und einer zielgerichteten ökologischen Transformation der Art und Weise, wie Stadtentwicklung und Wohnungspolitik gestaltet werden,stehen noch immer historisch und systemisch bedingte Pfadabhängigkeiten im Weg. Diese werden nur durch eine integrierte Betrachtung sozialer und ökonomischer Aspekte sichtbar und deuten auf eine der ursprünglichen Fragen linker Gesellschaftsforschung hin: Die Auseinandersetzung mit dem Verhältnis von Eigentum und Gerechtigkeit.
Im Ergebnis stehen drei wesentliche Befunde: Der Diskurs zum Schutz des Klimas und der Biodiversität berührt direkt die Parameter Dichte, Nutzungsmischung und Flächeninanspruchnahme; zweitens steigt letztere relativ mit erhöhtem, individuell verfügbaren Kapital und insbesondere im selbstgenutztem Eigentum gegenüber Mietwohnungen; und drittens wächst der Eigentumsanteil mit fortschreitender Finanzialisierung des Wohnungsmarktes, sodass das Risiko sozialer und ökologischer Krisen sich verschärft.

Die Arbeit beschäftigt sich mit den diskursiven Konstruktion urbaner Images in Großprojekten. Aufbauend auf einer soziologischen Definition der Begriffe „Raumbild“ und „Ortsbild“ wird am Beispiel des städtebaulichen Großprojekts Paris Rive Gauche untersucht, wie sich ortsspezifische Referenzen in einem Planungsprozess bilden, zu welchen Zwecken sie eingesetzt werden und wie mit Hilfe dieser Referenzen im Planungsprozess diskursiv ein Image für einen entstehenden Stadtteil konstruiert wird.
