In this paper, we investigated the trade-offs between social, psychological, and energy potential of the fundamental elements of urban form: the street network and the building massing. Since formal mehods to evaluate urban form from the psychological and social point of view are not readily available, we developed a methodological framework to quantify these criteria as the first contribution in this paper. To evaluate the psychological potential, we conducted a three-tiered empirical study starting from real world environments and then abstracting them to virtual environments. In each context, the implicit (physiological) response and explicit (subjective) response of pedestrians were measured. To quantify the social potential, we developed a street network centrality-based measure of social accessibility. For the energy potential, we created an energy model to analyze the impact of pure geometric form on the energy demand of the building stock. The second contribution of this work is a method to identify distinct clusters of urban form and, for each, explore the trade-offs between the select design criteria. We applied this method to two case studies identifying nine types of urban form and their respective potential trade-offs, which are directly applicable for the assessment of strategic decisions regarding urban form during the early planning stages.}, subject = {Planung}, language = {en} } @article{XinHijaziKoenigetal., author = {Xin, Li and Hijazi, Ihab Hamzi and K{\"o}nig, Reinhard and Lv, Zhihan and Zhong, Chen and Schmitt, Gerhard}, title = {Assessing Essential Qualities of Urban Space with Emotional and Visual Data Based on GIS Technique}, series = {ISPRS INTERNATIONAL JOURNAL OF GEO-INFORMATION}, journal = {ISPRS INTERNATIONAL JOURNAL OF GEO-INFORMATION}, doi = {10.3390/ijgi5110218}, url = {http://nbn-resolving.de/urn:nbn:de:gbv:wim2-20170401-30995}, abstract = {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.}, subject = {Stadt}, language = {en} } @article{KnechtKoenig, author = {Knecht, Katja and K{\"o}nig, Reinhard}, title = {Automatische Grundst{\"u}cksumlegung mithilfe von Unterteilungsalgorithmen und typenbasierte Generierung von Stadtstrukturen}, doi = {10.25643/bauhaus-universitaet.2673}, url = {http://nbn-resolving.de/urn:nbn:de:gbv:wim2-20160822-26730}, abstract = {Dieses Arbeitspapier beschreibt, wie ausgehend von einem vorhandenen Straßennetzwerk Bebauungsareale mithilfe von Unterteilungsalgorithmen automatisch umgelegt, d.h. in Grundst{\"u}cke unterteilt, und anschließend auf Basis verschiedener st{\"a}dtebaulicher Typen bebaut werden k{\"o}nnen.

On the basis of a dielectric breakdown model in combination with cellular automata, we present a method to steer precisely the generation of settlement structures with regard to their global and local density as well as the size and number of forming clusters. The resulting structures depend on the logic of how the dependence of the settlements and the road network is implemented to the simulation model. After analysing the state of the art we begin with a discussion of the mutual dependence of roads and land development. Next, we elaborate a model that permits the precise control of permeability in the developing structure as well as the settlement density, using the fewest necessary control parameters. On the basis of different characteristic values, possible settlement structures are analysed and compared with each other. Finally, we reflect on the theoretical contribution of the model with regard to the context of urban dynamics.}, language = {en} } @article{Koenig, author = {K{\"o}nig, Reinhard}, title = {Die Stadt der Agenten und Automaten}, series = {FORUM - Architektur \& Bauforum}, journal = {FORUM - Architektur \& Bauforum}, doi = {10.25643/bauhaus-universitaet.2608}, url = {http://nbn-resolving.de/urn:nbn:de:gbv:wim2-20160622-26083}, abstract = {PLANUNGSUNTERST{\"U}TZUNG DURCH DIE ANALYSE R{\"A}UMLICHER PROZESSE MITTELS COMPUTERSIMULATIONEN.

The level of complexity rises with each aspect to be considered and makes it difficult to find universally satisfactory solutions. To improve this situation we propose a new approach, which complement traditional design methods with a computational urban plan- ning method that can fulfil formalizable design requirements automatically. Based on this approach we present a design space exploration framework for complex urban planning projects. For a better understanding of the idea of design space exploration, we introduce the concept of a digital scout which guides planners through the design space and assists them in their creative explorations. The scout can support planners during manual design by informing them about potential im- pacts or by suggesting different solutions that fulfill predefined quality requirements. The planner can change flexibly between a manually controlled and a completely automated design process. The developed system is presented using an exemplary urban planning scenario on two levels from the street layout to the placement of building volumes. Based on Self-Organizing Maps we implemented a method which makes it possible to visualize the multi-dimensional solution space in an easily analysable and comprehensible form.}, subject = {Stadtgestaltung}, language = {en} }
