Anhand einer Fallstudie wird die Arbeit mit dem von der Freiberg Institut für Energie und Klimaökonomie GmbH erschaffenen H2-Tankstellen-Konfigurators dargestellt. Durch die Variation der Wasserstoffversorgung einer fiktiv geplanten H2-Tankstelle wird verdeutlicht, wie die Optimierungssoftware Edgar die Dimensionierung der Anlagentechnik für eine optimale Konfiguration und minimale Kosten verändert., A case study is used to illustrate the work with the H2 filling station configurator created by the Freiberg Institute for Energy and Climate Economics GmbH. By varying the hydrogen supply of a fictitiously planned H2 filling station, it is illustrated how the optimization software Edgar changes the dimensioning of the plant technology for an optimal configuration and minimal costs.

The positive influence of urban green spaces on human health and well-being is well known while the pathways are little understood. Past research has largely focused on visual stimuli, yet the auditory pathway is also an important means for contact with nature.The sonic environments of urban green spaces, however, are rarely entirely natural and many differ in their composition of natural sounds and anthropogenic noise. Few studies have investigated how these differences may impact the restorative potential of these soundscapes and, in particular, how the presence of traffic noise may constrain the benefits of natural sounds.To address this gap, we examined differences in the perceived restorativeness and perceived restorative outcomes across a gradient of eight park soundscapes that differed in bird and traffic sounds. In a laboratory setting, 162 participants listened to sound samples and reported on perceptions of the soundscapes and restorative potential and outcomes.The results strongly indicate that park soundscapes with a rich array of perceived bird sounds and minimal perceived traffic noise offer the greatest perceived restoration. Traffic noise was found to moderate the positive effect of bird sounds. The duration of time lived in the city and noise sensitivity were also positively associated with greater perceived restorative benefits while noise-sensitive people were also more negatively affected by traffic noise.The promotion of highly natural soundscapes in urban green spaces and the reduction of traffic noise can provide nature-based solutions to human health and well-being in urban areas.
