3 Stuttgart area (relief) Stuttgart S-West 3

4 Pilot action area High number of historical residential buildings, that have to be preserved inhabitants in Stuttgart West. 4

5 Identification and characterisation Number of days with high thermal stress (annual average) very high UHI high UHI moderate UHI low UHI low UHI low UHI very low cold air area low cold air area low cold air area cold air area Thermal stress (UHI-classification) 5

6 Identification and characterisation cold air current density (m³/ms) 6

7 Development of realisable measures (simulation on the regional scale) JOACHIM FALLMANN, STEFAN EMEIS, KIT 7

8 Example redesign of the Olga Hospital Setup for Envimet simulations (case studies) Envimet simulations for a typical summer day Christine Ketterer, Andreas Matzarakis, University Freiburg 8

9 Consequences from the simulations of KIT and University Freiburg Reduction of UHI by cool colours less building density small or large parcs planting trees green in the inner area of blocks of houses ventilation corridors 9

13 Development Outline Plan Stuttgart-West Talgrund For Stuttgart-West a development outline plan is under progress by the planning department. Instrument to set up the urban planning strategy for the sustainable future development and restructuring of single city districts weighting all aspects of urban living, economy and nature, environment and climate (UHI). Measures for reducing the thermal stress are implemented. The measures comprise an optimised design of buildings and public spaces, a realisable greening and the facilitation of the natural ventilation. 13

14 Optimisation: Optimised building structure Gaps between the buildings facilitate the ventilation of the inner area. Greened courtyard. Buildings inside the block with green roofs and limited height. Buildings around the block should be equipped with green roofs, but it is not compulsory. Facades which are orientated to the south have to be greened or designed with cool materials. 14

15 Rebuilding activity (finished) Example for a rebuilding activity inside the pilot action area (Rossbollengässle) Initial situation Rebuilding process Situation after finishing the activity 15

16 Optimised design of street canyons and creation of green connections in Stuttgart-West Thermal stress is reduced due to facade greening and the use of cool materials for facades (green lines). Green circles marking possible positions for trees. Green connections 16
