HEAT
Excess mortality
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
CLIMATE RESILIENT / LIVABLE?
Wat gebeurt er al?
Laura Kleerkoper, Amsterdam University of Applied Sciences
Urgency?
- Measurements?- Model (simple complete)
- start simple quick scan - Data lidar 0,5*0,5, water, green- assumptions
- Deltares & Tauw HDSM, 2014
Principle of Urban Heat Map
Air temperature Groningen- Red is hotter,
- Blue is cooler
Air temperature Groningen during heat wave
Heat stress map, detailed
Heat maps
• Air temperature• Comfort temperature
• PET Physiological Equivalent Temperatuur

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

Heatstress map – effect trees
Expected PET 4th of juli ’15, Utrecht
Estimate of PET 2050 – end of hot day
Estimate of PET 2050 – end of hot day
Design urban space
• Adaptation Support Tool (AST)• Insight in ‘hot’ spots• Insight in • Planning Effect of measures like
– Water– Trees/green
