District cooling is building upon the economies of scale. A district cooling system is the production and distribution of chilled water from a central facility to multiple buildings. The system pumps chilled water through a network of pipes to buildings and developments for air conditioning purposes. District Cooling is widely used in business districts and institutional settings such as college campuses, plazas, hotels and high-rise towers. When a district cooling system is used, buildings no longer need to own and operate their own chillers or air conditioners.

Benefits of Connection

The district cooling system works by displacing peak electric power demand with thermal storage using ice or chilled water. This benefits the local power grid by reducing peak power demand and alleviating power congestions due to power transmission limitations in cities helping to challenge problems posed by high electric consumptions.

District cooling can reduce up to 20% of noise pollution due to its concealment underneath streets, in addition to proving to be a major contributor to the reduction of greenhouse gases.

The system also provides a variety of benefits, both in the quality of service and economical advantages. The qualitative advantages are perceived in terms of better comfort, reliability and maximised convenience. Mechanical cooling and air conditioning requirements are growing rapidly throughout the world, partly because there are many new buildings built in warmer climates. However, no matter where those buildings are built, they tend to be more densely packed than they used to be creating the need for air conditioning.

Economic benefits can be experienced by both the owner and the tenant, where the capital costs of control panels, internal power distribution, annual maintenance and power consumption inside the building are reduced and the cost of chillers are eliminated.

Benefits of District Cooling

  • Substantial reduction in capital costs
  • Substantial energy savings
  • 20% reduction in noise pollution
  • Increased floor space for a more profitable use
  • Tenant and user comfort
  • Money better spent for the cooling energy consumed instead of being locked in equipment
  • Environmentally friendly and virtually maintenance free services
  • Individual space or room temperature control using multiple indoor fan-coil units
  • Better indoor humidity control
  • Standby units are available at every cooling facility
  • High-tech industrial units dramatically decrease the failure frequency compared to commercial equipment. District cooling reliability is in excess of 99.94%*
  • The average lifespan of industrial equipment is 30 years compared to 15 years for commercial equipment
  • There is around the clock operation and maintenance at the central plant room ensuring preventive maintenance and swift responses
