1 Urban Development Planning in the Context of Climate Adaptation StEP Klima KONKTRET 2016

2 Agenda I. Berlin, the effects of climate change II. III. Berlin, the growing city Berlin, the adaptation to climate change

3 Berlin walks to the south climate simulation for 12 European cities ca Kopf, Sebastian; Ha-Duong, Minh; Hallegate, Stephane, ( halshs , version 2-15 May 2008) 1. Berlin, the effects of climate change

4 Bio climate during the night the affected areas affected areas today: 18% of the whole town area 42% in the inner circle Urban development and climate change in Berlin 23. Mai Berlin, the effects of climate change

5 Bio climate during the night the affected areas affected areas in 2050: 44% of the whole town area 76% in the inner circle Urban development and climate change in Berlin 23. Mai Berlin, the effects of climate change

6 Bio climate during the night the affected areas affected areas today: 18% of the whole town area 42% in the inner circle affected areas in 2050: 44% of the whole town area 76% in the inner circle Urban development and climate change in Berlin 23. Mai Berlin, the effects of climate change

7 Berlin is a growing city! population in population in refugees 2. Berlin, the growing city

8 Population forecast is the foundation for strategic planning: For example: the current housing policy situation today: a shortage of payable apartments situation in future: additional approx units of payable apartments Urban development plan Housing 2. Berlin, the growing city

9 Urban development plan Housing 2. Berlin, the growing city

10 The main questions: What is a suitable density of settlement for a good urban climate? How we can design new housing areas so that they will not be contrary to climate change adaptation? The answer: We need both: Newly-built flats, especially inside and measures for adaptation, which have good effects, will be accepted and feasible. Conversion of former Tempelhof airport Graft/Kiefer 3. Berlin, the adaptation to climate change

11 Urban development plan climate Stadtentwicklungsplan Klima KONKRET 2016 LEITTHEMEN UND ANPASSUNGSMAßNAHMEN 3. Berlin, the adaptation to climate change

12 Stadtentwicklungsplan Klima KONKRET 2016 Main topic: the urban heat Main topic: flooding down town caused by heavy rain Principle of the sponge city 3. Berlin, the adaptation to climate change

13 The Urban Heat Evaporation of water Small evaporation / transpiration in the inner city effect of cooling Bio climate, the affected areas bgmr Umweltatlas: Abnahme der Verdunstung mit der Zunahme der baulichen Dichte der Stadtstruktur; Karte Verdunstung aus Niederschlägen Ausgabe 2013 bgmr StEP Klima Analysekarte Bioklima, Wärmebelastung bei Nacht heute und künftig: betroffene Siedlungsräume 3. Berlin, the adaptation to climate change

14 The sponge city a new strategy for the urban open space the urban surface is a water storage roofs, façades, urbane wetlands sponges 3. Berlin, the adaptation to climate change

15 Design of roofs - C Wassergärten Sonderformen Blau- Grünes Dach Grünes Dach - intensiv Mehrfachgenutzte Dächer Grünes Dach - extensiv Blaues Dach Dächer mit stärkerer Neigung Albedodach Konventionelles Dach 3. Berlin, the adaptation to climate change

16 - C Design of façades Bewässerung Horizontale fassadengebundene Begrünung mit Bewässerung Vertikale fassadengebundene Begrünung mit Bewässerung Begrünung Bodengebundene Fassadenbegrünung Hauswand Bodengebundene vorgehängte Fassadenbegrünung Albedo Verschattung Aktiv verschattete Fassade Passiv verschattete Fassade / Baum Passiv verschattete Fassade /Arkaden Konventionelle Fassade Über sonnenexponierte Fassaden heizen die Gebäudekörper auf 18

17 Design of urbane wetlands Typ Cooling power Orte der Anwendung Wasserflächen Parks, Stadtplätze, private große Freiflächen (z.b. in Zeilenbebauung, Krankenhäuser... ) Pflanzenbestandene Wasserflächen Parks, private große Freiflächen (z.b. in Zeilenbebauung, Krankenhäuser... ) Schwimmende Vegetationsinseln Wasserflächen: Still- und Fließgewässer, Kanäle in Urban Heat Gebieten Verdunstungsbeete Straßenraum, Stadtplätze Wasserspiele / Brunnen Stadtplätze Wasserversorgtes Grün Parks, private große Freiflächen, kleinteiliges Grün Grünblaue Fassaden und Dächer Gebäude, Überdeckelung Tiefgaragen

18 - C Albedo / Solar reflectance index Oberfläche: Erhöhung der Rückstrahlwirkung von Oberflächen zur Reduktion der Aufheizung Anwendung : Dächer Boden Fassaden Potentiale der Rückstrahlungserhöhung Albedo verschiedener Oberflächen (aus: StEP Klima 2011, SenStadtUm; Fotos: Mayang, Back) 3. Berlin, the adaptation to climate change

19 Application of adaptation tools to several urban structures 1. traditional block edge building 2. Rows of housing with densification 3. Newly built flats 4. Trade and industry 5. Infrastructures / schools Nr. 1 Nr. 2 Nr. 3 Nr. 4 Nr Streets and squares 7. green and open spaces 3. Berlin, the adaptation to climate change

20 Nr. 1: traditional block edge building 3. Berlin, the adaptation to climate change

21 Nr. 2: Rows of housing with densification 3. Berlin, the adaptation to climate change

22 Nr. 3: Newly built flats 3. Berlin, the adaptation to climate change

23 Nr. 4: Trade and industry

24 Nr. 5: Infrastructure/ schools 3. Berlin, the adaptation to climate change

25 Nr. 6: Streets and squares 27

26 Nr. 7: green and open spaces Klimatisch idealtypische Verteilung von Senatsverwaltung für Stadtentwicklung und Umwelt Berlin Abteilung I Referat I A Dr. Heike Stock Climate Grünflächen Metropole und + Initiative Bebauungsstruktur `15 3. Berlin, the adaptation to climate change

27 Conclusion: A succesful climate change adaptation needs an optimized combination of several tools. For this the basic is an integrated concept for an urban quarter.
