2. HEAT

3. Excess mortality

4. Heatstress
• Night  Excess mortality
• Health care
• Airco
• Spatial design
+ 10% green UHI 0,6 degree lower [CpC final report 2014)
Each day > 20 degree + 8 extra death in NL.
-  Livability, Economy
- More green, distance to green, walking ways
- Urgency?  quick scan
- Deltares & Tauw  HDSM, 2014

5. CLIMATE RESILIENT / LIVABLE?

6. Wat gebeurt er al?
Laura Kleerkoper, Amsterdam University of Applied Sciences

7. Urgency?
- Measurements?
- Model (simple  complete)
- start simple  quick scan
- Data  lidar 0,5*0,5, water, green
- assumptions
- Deltares & Tauw  HDSM, 2014

8. Principle of Urban Heat Map

9. Air temperature Groningen
- Red is hotter,
- Blue is cooler

10. Air temperature Groningen during heat wave
Heat stress map, detailed

11. Heat maps
• Air temperature
• Comfort temperature
• PET Physiological Equivalent Temperatuur

12. Aim
- Comfort temperature – measurements/opinion
- Advice for spacial design
- Examples of
• climate robust design

13. Heatstress map – effect trees

14. Expected PET 4th of juli ’15, Utrecht

15. Estimate of PET 2050 – end of hot day

16. Estimate of PET 2050 – end of hot day

17. Design urban space
• Adaptation Support Tool (AST)
• Insight in ‘hot’ spots
• Insight in
• Planning  Effect of measures like
– Water
– Trees/green
