How cities can stay cool on a warming Earth

  • District cooling reduces peak power capacity requirements, because it does not need to meet large spikes in demand.
  • Our analysis shows that using district cooling where appropriate to meet future additional cooling demand could reduce the total energy required for cooling by 16 percent, leading to more than US$1 trillion in energy savings worldwide through 2035.

  • However, the power capacity required for cooling will increase faster than the number of units, rising by 78 percent by 2035.
  • Given these challenges, the IEA has called for increasing the efficiency of traditional air conditioning systems through interim measures such as minimum energy performance standards, better building designs, and stricter building codes.
