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
