UHI and mapping heat impact on health
• Heat stress High temperatures and humidity stress the body's ability to cool itself, and heat illness becomes a special concern during hot weather.
• Some factors increase the risk of heat stress– Old people– Single– Sick– Being hospitalized– …
• Heat stress depends on several factors

UHI and mapping heat impact on health
UHI and mapping heat impact on health
• Climatic parameters– Temperature (e.g. apparent max t°) and humidity– Temperature variability (day max t°, night min t°, interval, duration)– Wind speed and direction…
• Urban morphology parameters– City centre vs residential area– Green area and water place– Open space, street canyon– Buildings variables (material, albedo, orientation…)…
• Demographic, socio-economic and health parameters– Age and gender– Marital Status– Economic status and educational level– Health conditions, medication and disease…

Selection of 3 end users
• Selection of number of relevant stakeholders– Interested in benefiting from an analysis of the impacts of
climate change on their urban dimension
Three European cities – Antwerp (BE) – Berlin (DE) – Almada (PT)
NACLIM annual meeting – 1/10/2013 11
Selection of 3 end users
• Antwerp (BE)− Major port − Population density 2,500/km2
− 20% green and blue urban areas − Maritime temperate climate
• Berlin (DE) − Metropolis counting 3.5 million inhabitants− Population density 3,700/km2
− 20-29 % green and blue urban areas − Warm-Summer Continental climate
• Almada (PT)− Small city densely populated− Nearby Lisbon metropolis − Population density is 2,355 / km2
− Mediterranean climate and close to Atlantic ocean

NACLIM annual meeting – 1/10/2013 13
June 2013 - 1st end user : Berlin and Antwerp
• Themes and services identified– Scenario linked to urban planning: the effect of UHI today and
in the future on urban planning– Scenario using existing urban plans/projects
• Impacts of green roofs linked to green roof potential map/plan (2030-2040)
• Impacts of change albedo (reflectivity) of buildings (roofs…)• …
– Scenario using projected population figures• Densification population and new settlements • Vulnerable population (school and old people)• …
– Impact of city expansion on climate change (e.g. projected LULC)
NACLIM: Almada end-user workshop - 24-25/09/2013 14
June 2013 - 1st end user : Berlin and Antwerp
• Time frame to be used in simulation are – Current situation (2000-2010)– Mid term (2030-2040) – Long term prediction (2100)
• Resolution vs extent– Larger extent (full city) with 250 m resolution– Smaller extent (part of city) with 100 m resolution
• Seasonal studies• Summer• “Winter”

NACLIM annual meeting – 1/10/2013 17
September 2013 : Almada end user workshop
• Themes and services identified– Identify hotspots in city
– Population exposure to heat waves• For ex. Last summer heat wave (2013)
– Prediction/projection for 2100 as a help to downscale adaptation
– Possible to identify 3 spots in the city for high resolution study to make diagnose out of the scope of NACLIM

Work in progress
• UHI modelling: UrbClim pre-processing input data– Variables/parameters
• Current work :– Planar area Index (PAI): proportion of area covered by buildings per
grid cell
– Frontal area indexes (FAI): area of buildings projected into the plane normal to the incoming wind direction and is a function of orientation per grid cell
– Average building height weighted with the building area and its variance
– Sky view factor (SVF)
• Outstanding work:% urban land use, land use type, % vegetation …
NACLIM annual meeting – 1/10/2013 21
Work in progress
• Berlin end-user case
– Available data• 3D building layers• Street network
– Study extent = Vito grid• Not full building coverage
– Extrapolation of PAI and FAI Evaluation of relationship at 1km resolution between EEA SS and PAI/FAI
