What stands out

What we found in Cistella

It comes from matching each building with its neighbourhood, its street, the nearest watercourse and its surroundings.

1

Where there are fewer trees, 5,2 °C hotter

5,2 °C

Around homes with between 5 and 10 % tree cover, the surface in summer is 1,0 °C above the median for Cistella; with more than 40 % tree cover, 4,2 °C below. 1 homes are in surroundings with almost no trees.

Ground surface temperature (Landsat), not air temperature. More trees usually go with less asphalt and lower density: this is a correlation, not a measure of the effect of planting trees.

2

From 6 to 39 tropical nights a year

6→39 nights

In a typical building in Cistella, nights when the temperature stays at or above 20 °C would rise from 6 a year (1991-2020) to about 39 by 2050. For this reason, 0 % of homes would be at a high or very high level.

66 in every 100 buildings were built before 1980

66 %

They were built before the first thermal insulation standard (1979). With 39 tropical nights a year by 2050, they will hold the most heat at night and have the most to gain from a retrofit.

Year of construction from the Cadastre.

94 homes at very high wildfire risk

123 buildings

These are 123 buildings right next to vegetation that can burn. Almost all are houses (122), on the edges of the town and in housing estates.

Proximity to woodland and to burnt areas (ESA WorldCover, EFFIS). It does not measure the state of the vegetation or any firebreaks.

What can be done

For the town council and for residents

For the town council and its technical staff

  • Climate shelters, and late-afternoon and evening opening hours at libraries and community centres in the areas with the most tropical nights.
  • Firebreaks and evacuation routes in the streets that border woodland.
  • Download the tables by area, neighbourhood, street and watercourse (Data tab) to cross-check them with urban planning.

For residents

  • Air your home in the early hours, shade west-facing walls from the sun and ask about grants to insulate the roof.
  • Keep the strip around your house clear of dry vegetation and know both ways out of your street.
  • Look up your building: the free report gives its level for each hazard, and the Climate Note gives the full detail.
