Pleasurescapes on the Edge: Performing Modernity on Urban Waterfronts (1880-1960)
Get PDF“Pleasurescapes,” also called amusement or entertainment quarters, are public spaces that are constituent for modern cities. They emerged during the period of urbanization and were constantly reshaped and negotiated. “Pleasurescapes” is an analytical concept that describes and reflects the historical, spatial, sociocultural, and infrastructural development of pleasure spaces during the long turn of the century around 1900. This issue explores the particular role of pleasurescapes on waterfronts and in port cities
Agent-based modeling (ABM) for urban neighborhood energy systems: literature review and proposal for an all integrative ABM approach
Get PDFAdvancing the energy transition in real-world urban settings is attracting interest within interdisciplinary research communities. New challenges for local energy balancing arise particularly in urban neighborhoods where densely populated buildings are facing the needs of the heat transition, an increasing use of battery-electric vehicles and an expansion of renewable energies. Agent-based modeling (ABM) is a suitable approach for addressing various interlinked aspects like market mechanisms and processes, technology adoption, different stakeholder roles and the formulation of policy measures. In this work, we analyze peer-reviewed, open-access literature on ABM for energy neighborhoods and discuss key modeling aspects like model purpose and outcome, the logic of agents and decision-making, the treatment of space and time, and empirical grounding. These ABM allow the study of local market mechanisms, local renewable energy generation, microgrids, the unfolding of heat transition, neighborhood mobility and the evaluation of policies like regulation and financial incentives. We find a lack of integrated neighborhood energy assessments that simultaneously look at the different energy forms and applications: heating, electricity, and mobility. We present a consolidated ABM concept that integrates these sectors. Thus, our work contributes to the advancement of ABM and to the understanding of how to promote the transition to a decarbonized society in urban settings
Geometric accuracy investigations of terrestrial laser scanner systems in the laboratory and in the field
Get PDFThis paper summarizes recent research into current terrestrial laser scanners undertaken by the HafenCity University Hamburg and gives an assessment of the geodetic accuracy of the latest generation of scanners. Three separate independent test methods are presented to investigate the geometric accuracy of terrestrial laser scanners under laboratory conditions: (a) distance measurement accuracy to b/w targets and spheres on the 20-m comparator track, (b) comparison of spatial distances in the 3D test field on b/w targets, and (c) investigation of the flatness deviation following the guideline VDI/VDE 2634 (VDI/VDE 2012) on a flat stone slab. The following laser scanners were tested in the lab: Leica BLK360 (2017), Leica RTC360 (2019), Z+F IMAGER 5016 (2019, 2020), Z+F IMAGER 5010 (2020), and Faro Focus3D X330 (2020). The reference measurements were realised with the Leica Absolute Tracker AT960 (2017, 2020) and with the Leica TS60 total station (2019). The results of the geometric accuracy tests in the laboratory show very small deviations in the range of 1–2 mm for most of the scanners, thus corresponding to the manufacturer’s specifications. In addition, five laser scanners were tested in accordance with instruction sheet 7-2014 of the German Society for Geodesy, Geoinformation and Land Management (DVW) for standardised testing of terrestrial laser scanners in the outdoor area of HafenCity University Hamburg. For the execution of the field test procedure, only the standard equipment and software of the respective manufacturers were used. The entire field test procedure, including data acquisition and evaluation, was completed within 4 to 5 h for each scanner. As expected, no significant distance or angle deviations were detected in any of the measurement systems, so that the tested laser scanners are ready-to-use, taking into account the measurement volume recorded

Get PDFTransformation Pathways Towards Climate Resilient Cities: A Comparative Analysis of Halle (Saale) and Mannheim, Germany
Get PDFThis article explores the enabling factors and actors involved in the transformation pathways towards climate resilience of two German cities: Halle (Saale) and Mannheim. A specifically developed analytical framework served as basis for making the complex developments of the transformation paths of the two cities visible and comparable. The analysis has shown that despite strong similarities in terms of climate change impacts, the cities acted under very different political and economic conditions and thus applied particular strategic and tactical approaches and steering instruments. It can be stated that preparation of climate strategies, creation of a supporting central unit for climate issues and exemplary implementation of selected measures by the administration, as well as awareness-raising and cooperation with the stakeholders and citizens have played a key role in the cities' transformation. In both cities, the city administration took the role of innovation organiser and orchestrated the pathway towards becoming climate resilient
Public space and environmental behaviour: weekly markets in Hamburg, Germany
Get PDFLimiting warming to 1.5°C above pre-industrial levels requires a large-scale effort to promote sustainable behaviour. The surrounding environment has a determinant influence on human behaviour and can therefore become a strategic ally towards sustainability. Using a multi-method approach in two weekly markets in Hamburg, this paper analyses how different features of the public space – like accessibility – facilitate the implementation of strategies typically aimed at the promotion of environmental behaviour – like information. The analysis shows that the two settings enable the implementation of all the revised strategies, pointing out the relevance of the public space towards more sustainable cities. Physical access in terms of public transportation and free-barrier zones played a major role facilitating the implementation of all the revised strategies while symbolic access in the form of a sophisticated atmosphere suggested a barrier for low-income groups. Visual access and opportunities for socio-cultural exchange acted together: The environment influenced behaviour through social norms-based strategies via observing what others do, role model-based strategies via sellers and information-based strategies via the spread of different types of information. In the same way, it drove subconscious decision-making throughout salience and priming-based strategies in the form of an extensive usage of signage. Regarding opportunities for economic exchange, availabilitybased strategies in the form of products and services played a major role, in accordance with the commercial nature of the markets. Opportunities for sensory experiences were supported by a variety of elements that created full lived-in experiences like smells and live music, which in turn might enhance the desired effect. Concerning situational features, the analysis suggests that a linear arrangement of stands provides quicker and easier access to products compared with a grid form
