Surfacepermeability

Excessive sealing of the city's surface causes rapid rainwater runoff, limits its retention, and is also one of the main causes of urban heating and the formation of urban heat islands. The lack of sustainable spatial planning in this regard also affects air quality and resilience to extreme weather events. Conscious residents are increasingly demanding the 'unsealing' of cities.

CITY PROBLEMS

Thanks to investments in the 'Sponge City' concept, Los Angeles absorbed 32.6 billion liters of rainwater in 6 days, which corresponds to the annual consumption of 100,000 homes.

Performs an inventory of areas

  • sealed
  • permeable
  • poorly permeable

Calculates the sealed area / biologically active area (BAA) index in various units

    Identifies areas with most sealed surfaces for intervention.

      Allows for assessing the impact of unsealing the area and pricing the solution.

        Monitors changes in the share of sealed areas / biologically active areas.

          Effects for the city

          • Urban space without large sealed areas

          • Control of the biologically active area of investments

          • More effective city de-sealing policy

          • Better conditions for tree development thanks to access to water and soil

          Testimonial image

          Thanks to CoolCity, designers can quickly check for flooding, retention, or the impact on heat islands and immediately include blue-green solutions. Then they are not an addition, but an integral part of the project – often cheaper than gray infrastructure, allowing to reduce current costs in the future, especially those related to the use of the environment.
