Cooling Cities

Sustainably turning urban heat islands (UHI) into "urban cool islands"

Overheated cities and public spaces in urban zones; more intense and frequent heatwaves; abnormally high death rate and a widely thermal discomfort not only in summer… all these phenomena related to urban heat islands (UHIs) can easily find sustainable solutions, and that is why 2EI Veolia created Cooling Cities. This custom-made offer will help you to find the best and sustainable solutions to convert your UHIs into efficient "urban cool islands" and guide you on the path to implementing innovative tools and complementary methodologies.

Whether you are a city, a large urban area, an urban planning agency, a public facility (school, hospital…) or a private facility (office headquarters, shopping centre), it’s time to explore the 4 steps of Cooling Cities.

Benefits

  • A personalised roadmap.
  • Advice adapted to your economic development objectives, and to your environmental and public health commitments.

 

Scale and timing

  • Complete territory, city or zone
  • 3 months

 

STEP 2 : Environnemental study of high-priority urban heat islands

 

Goal : Define the possible technical solutions according to your local specificities.

 

The offer for each urban heat island

  • A multi-criteria analysis of possible solutions according to your local particularities.
  • Modeling using the Envimet tool.
  • Proposals for tailor-made technical solutions.

 

Benefits 

  • A precise analysis of the ecosystem of each site.
  • Access to a wide range of personalised solutions.

 

Scale and timing

  • At site level for each high priority UHI selected
  • 3 months per site

 

STEP 3 : Modeling solutions for each urban heat island

 

Goal : Guide you in choosing the best solutions to implement.

 

The offer

  • A comparison of planning scenarios through many cross criteria.
  • The use of EVA ("Eau-Végétation-Albedo"), a multi-criteria assessment tool developed by 2EI and IRSTV (Institut de Recherche en Sciences et Techniques de la Ville).
  • Recommendations on the implementation of solutions. 

 

Benefits

  • Concrete solutions to solve locally the UHI effect.
  • Expertise and accuracy to find the most appropriate solutions depending on the local context. 

 

Scale and timing

  • At site level for each high priority UHI selected
  • 3 months per site

 

STEP 4 : Performance monitoring

 

Goal : Support you during the implementation of solutions and for performance monitoring.

 

The offer

  • Support and monitoring throughout the implementation of solutions.
  • Installation of monitoring sensors.
