Paris Fights Heatwaves with Innovative River-Based Cooling

Facing increasingly severe summer heat waves, Paris is aggressively developing an innovative system that uses the Seine River water to cool buildings. This system transfers heat from buildings to the river water through heat exchangers, maintaining high cooling efficiency even when the river water is warm in summer, reaching up to 15 times the efficiency of conventional air conditioning in winter. However, with rising summer temperatures, the system faces new challenges. How to further improve cooling capacity while protecting the environment has become a crucial issue for Paris to address.
