Benefits of District Cooling
Benefits for Users:
- District Cooling is 40% - 60% more energy efficient than conventional systems.
- It has substantially lower operating costs, higher operating reliability and availability.
- It reduces construction cost as air-conditioning systems typically constitute up to 10% of overall building costs. By outsourcing air-conditioning requirements, developers are able to reduce their overall building cost.
- District Cooling reduces maintenance costs as air-conditioning systems, especially in large buildings, require regular professional maintenance.
- District Cooling improves air quality and temperature control. These are normally difficult to monitor and regulate, especially if the system is operating below optimal levels.
- District cooling offers a high potential for economies of scale through the use of a single central unit to replace multiple individual units.
- District Cooling increases revenue-generating potential. Air conditioning systems are usually installed on the roof or in individual offices/apartments. By utilizing district cooling, these air-conditioning units are no longer required.
Benefits for Community:
- Reduces CO2 emissions
- Enhances aesthetics and improves local environments by such means as eliminating noise and vibrations.
- Reduces energy consumption. Consumption by air-conditioning systems is estimated to peak at up to 70% of overall electricity consumption during the summer.
- Reduces pollution. Air-conditioning operators are under increasing pressure to comply with the Chlorofluorocarbon (CFC) phase-out imposed by the Montreal Protocol on substances that deplete the ozone layer. District cooling systems thus offer an alternative route to CFC.
- Offers cooling from a sustainable source.
Benefits for Government:
- DC is recognized as being potentially the biggest immediate win in terms of the impact on the supply side of the power equation.
- Because power is a subsidized commodity, impact on demand is an impact on national resources.
- Natural gas is a finite resource. Addressing the demand on power generation is, hence, part of the national gas conservation strategy.
- District cooling has an impact on the supply side of the equation and is a major quick win as a saving on carbon emissions.
- Efficiency with regards to cooling spaces can be seen in savings on power transmission/distribution networks, space (corridor consumption) and substation construction (66Kv, 11Kv,..) and associated cabling.
- Adopting district cooling increases a government’s credibility in pursuing an environmentally sustainable future
