Rising temperatures are driving a surge in cooling demand, compelling city planners and policymakers to rethink how urban areas can meet future cooling needs
As climate change intensifies, cities around the world are experiencing increasingly frequent and severe heat waves, placing unprecedented pressure on energy systems, urban infrastructure, and public services. These rising temperatures are driving a surge in cooling demand, compelling city planners and policymakers to rethink how urban areas can meet future cooling needs in an efficient, resilient, and sustainable manner.
District cooling offers a model based on producing chilled water at highly efficient central plants and distributing it through insulated pipe networks to meet the cooling needs of multiple buildings and facilities. Consolidating cooling demand within a single system enables the use of larger and more efficient equipment, improves load management, and reduces electricity consumption compared with operating separate systems for individual buildings.
District cooling systems can deliver electricity savings of up to 50% compared with traditional cooling systems, requiring approximately 0.9 to 1 kilowatt of electricity per ton of refrigeration, compared with 1.6 to 1.8 kilowatts for traditional systems. This difference becomes even more significant as the network expands to serve entire neighbourhoods and urban areas.
