SabadellClimate risk in its neighbourhoods, streets and rivers, today and in 2050

We have scored the climate risk of the 24.967 buildings in Sabadell using Cadastre data, satellite imagery and climate projections, and added it up by area, neighbourhood, street and watercourse. The clearest change comes at night: from 24 to 65 tropical nights a year by 2050.

What stands out

What we found in Sabadell

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

1

2.305 homes at very high wildfire risk

1.111 buildings

These are 1.111 buildings right next to vegetation that can burn. Of these, 11 are blocks of flats with 679 homes, where evacuation is harder.

  • Carrer de Begoña: 136
  • Carrer de Louis Braille: 122
  • Carrer de Can Llobateres: 95
  • Carrer de Milena Jesenská: 86

From 24 to 65 tropical nights a year

24→65 nights

In a typical building in Sabadell, nights when the temperature stays at or above 20 °C would rise from 24 a year (1991-2020) to about 65 by 2050. For this reason, 98 % of homes would be at a high or very high level.

Where there are fewer trees, 3,6 °C hotter

3,6 °C

Around homes with less than 2 % tree cover, the surface in summer is 0,6 °C above the median for Sabadell; with more than 40 % tree cover, 3,0 °C below. 20.491 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.

By 2050, el Centre would have about 67 tropical nights a year and Can Deu, 40. Altitude, closeness to the sea or a river, and trees make a big difference to heat within the same municipality.

75 in every 100 buildings were built before 1980

75 %

They were built before the first thermal insulation standard (1979). With 65 tropical nights a year by 2050, they will hold the most heat at night and have the most to gain from a retrofit.

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.
  • Shade and trees in the playgrounds of the 5 schools with the hottest surroundings.
  • Review with the river basin authority the watercourses with no official mapping that run next to homes, and keep them clear.
  • Firebreaks and evacuation routes in the streets that border woodland.
  • Monitoring of ground movement in Can Puiggener: cracks, water mains and buildings.

For residents

  • Air your home in the early hours, shade west-facing walls from the sun and ask about grants to insulate the roof.
  • If you live on a ground floor or have a garage next to a watercourse, have a plan: where to go upstairs, what to switch off and how to hear about warnings.
  • 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.
