“…In recent years, fundamental research has been done in the field of urban surfaces resulting, e. g., in the project BUOLUS, in the definition of the term and the categorization of urban surfaces based on Leistner et al [2] as well as a general life cycle of urban surfaces based on DIN EN 15978 [3] in Henzler et al [4] and an SDG-based impact assessment methodology tailored to urban surfaces in Henzler et al [1]. However, when it comes to carrying out the steps and applying the indicators proposed in [1,4] for a holistic sustainability assessment in the context of urban surfaces in municipalities, it becomes evident that there is a need for a simple guideline that helps local actors to navigate through the assessment process.…”

The consideration of sustainability aspects is becoming increasingly important at municipal level in order to implement the SDGs. Some municipalities already have their own concepts for individual SDGs, such as climate protection (SDG 13). There are many fields of action in which municipalities can initiate changes to contribute to the SDGs. An important field of action is the municipal task of planning, building and maintaining urban areas and surfaces sustainably. However, as this topic is quite complex, there is a need for a guide for municipalities on how to conduct such a sustainability assessment. The authors provide a practical guideline for communities to evaluate the sustainability impacts of urban surfaces and their management processes. The guideline has been developed with special focus on its applicability and the reduction of the complexity of the topic for local actors. The authors present the guideline, describe the underlying methods and the five subsequent steps that can be followed by a community in order to conduct a sustainability assessment. First, the scope of the sustainability assessment is defined by classifying the municipal urban surfaces and their management processes and analysing their relevance. Then, the sustainability of the prioritized surface and process is analysed by selecting relevant indicators, identifying the life cycle phases and researching sustainability impacts in the phases for the thematic priorities. For each phase and indicator, relevant municipal areas of action are determined, selected ones further refined and possibilities for their implementation investigated. The guideline operationalizes the sustainability assessment methodology for the management of urban surfaces proposed by Henzler et al. [1], which uses SDG-based indicators and life cycle thinking of LCA, considering the interaction between the life cycle of urban surfaces and their products.

Wie kann künftig mehr umbauter Raum mit weniger Ressourceneinsatz bei gleichzeitig deutlich reduzierten Umweltwirkungen geschaffen werden? Mit dieser Frage beschäftigen sich 14 Institute der Universität Stuttgart im Rahmen des Sonderforschungsbereichs (SFB) 1244. Die beteiligten Forschenden sehen in der Adaptivität ein großes Potenzial für einen Paradigmenwechsel in der gebauten Umwelt. Ihr Bestreben ist es, die Energie-, Material-und Emissionsbilanz von Tragwerken und Fassaden über den gesamten Lebenszyklus eines Gebäudes durch die Integration adaptiver Elemente zu optimieren.

“…On the other hand, in the sense of mitigation of global climate change, we must seek to establish growth of photosynthetic organisms as much as possible. There are already approaches in development that are focussing on the stimulation of favourable plants at buildings and the urban environment and simultaneously avoiding potentially harmful organisms [ 276 ].…”

This article gives a comprehensive overview on potentially harmful algae occurring in the built environment. Man-made structures provide diverse habitats where algae can grow, mainly aerophytic in nature. Literature reveals that algae that is potentially harmful to humans do occur in the anthropogenic environment in the air, on surfaces or in water bodies. Algae may negatively affect humans in different ways: they may be toxic, allergenic and pathogenic to humans or attack human structures. Toxin-producing alga are represented in the built environment mainly by blue green algae (Cyanoprokaryota). In special occasions, other toxic algae may also be involved. Green algae (Chlorophyta) found airborne or growing on manmade surfaces may be allergenic whereas Cyanoprokaryota and other forms may not only be toxic but also allergenic. Pathogenicity is found only in a special group of algae, especially in the genus Prototheca. In addition, rare cases with infections due to algae with green chloroplasts are reported. Algal action may be involved in the biodeterioration of buildings and works of art, which is still discussed controversially. Whereas in many cases the disfigurement of surfaces and even the corrosion of materials is encountered, in other cases a protective effect on the materials is reported. A comprehensive list of 79 taxa of potentially harmful, airborne algae supplemented with their counterparts occurring in the built environment, is given. Due to global climate change, it is not unlikely that the built environment will suffer from more and higher amounts of harmful algal species in the future. Therefore, intensified research in composition, ecophysiology and development of algal growth in the built environment is indicated.
