Schwammstadt - Concepts of city-wide, neighborhood- and building-related climate adaptation - focus on new construction.

Dr. Carlo W. Becker, bgmr Landschaftsarchitekten, Berlin
Marco Schmidt, Bundesinstitut für Bau-/ Stadt und Raumforschung sowie Technische Universität Berlin

It is well known that climate adaptation is necessary. Which measures are the necessary, suitable and realizable ones for the respective place requires a preparatory conceptual planning. In the context of the advanced training course the question is pursued, how such concepts of the climatic adaptation are compiled.

Basics / guiding principles / goals / concepts for action / measures / magnifying glasses / action plans

One focus will be the topic of the sponge city, i.e. the linking of stormwater management and heat prevention. The multicoding of the surface of the city will be in focus, climate adaptation is not a separate specialized planning, but requires a qualification of urban uses around the requirements of climate adaptation.

Three planning levels are addressed: City as a whole - City neighborhood - Object/building. For each of these planning levels, corresponding example projects are presented and discussed. It will be shown how climate adaptation concepts can be transferred to urban land use planning and where the limits are.

Examples of climate adaptation concepts will be discussed. For the building-related level, the example of the physics building in Adlershof is presented.

Concepts show possible measures and strategies, they form a framework for action. In the further events of the seminar series it will be deepened how these can be implemented concretely.

Using the example of Berlin-Adlershof, an excursion will show how such concepts are implemented structurally in terms of qualities, strategies and conflict potentials.

Heat stress and heavy rainfall - Blue-green infrastructure in public spaces.

In Hamburg, the focus of the events is on strategies and measures to reduce heat stress and flooding from heavy rain in public and semi-public spaces. A central type of space is the street space and urban squares in the inner-city dense context, has here, in addition to the traffic requirements, especially the quality of stay for pedestrians and cyclists a high priority.

An important basis of the input in the morning is fed by the results of the BMBF research project BlueGreenStreets, especially the developed toolbox for a climate-adapted streetscape planning. Innovative approaches to climate adaptation in road space were developed and tested for concrete road space planning in various cities in Germany.

Thematically, this can provide information on both the techniques used, their dimensioning, expected effects, urban design integration, the handling of existing pipelines, and the operation and maintenance of the systems. As a particularly innovative element, various types of tree trenches will be presented, which are being built as part of BlueGreenStreets and are currently being continuously evaluated.

In the afternoon, an excursion to an innovative neighborhood in HH-Weißenberge will take place. In the interaction of numerous types of measures of decentralized stormwater management, an innovative concept was built here, which allows the management of a 100-year event without a stormwater sewer. As a particularly innovative element, various so-called retention green roofs can be built, which can be visited.

Heat stress and heavy rainfall - climate-oriented redensification in inner-city neighborhoods.

In the final part of the workshop series, the possibilities of climate-oriented redensification in residential neighborhoods are considered. The focus is on the potential of green infrastructure to reduce heat stress and for sustainable heavy rainfall management.

To this end, research results will be presented on a real planning case in Munich, to which the excursion will also lead. Using the example of the redevelopment and competition area of Munich-Moosach, conflicting goals for redensification in the housing stock, but also development potentials, will be shown.

The method and results of modeling for thermal comfort, heavy rainfall and ventilation are presented and their application in practice is discussed.

Subsequently, the integration of climate aspects into planning instruments, such as the current framework plan and competition in Munich-Moosach as well as green space and open space design plans will be discussed.
