District Cooling System

Localized energy solution for district cooling system in Hong Kong

Hong Kong’s air conditioners account for 30 per cent of the city’s energy use each year. While cool air brings much comfort to the residents of the subtropical city, the heavy use of electricity to run air conditioning systems is in fact taking a toll on the air quality.

More energy-efficient air-cooling methods stand to bring remarkable improvements to Hong Kong’s health and wellbeing.

Veolia Solution

First-of-its-kind District Cooling System in Hong Kong 

Veolia has designed, built and operated the Kai Tak District Cooling System (DCS). The facility uses seawater as a cooling medium to produce chilled water to consumer buildings in the Kai Tak District, to replacing traditional decentralised air-conditioning systems in the consumer buildings. Chilled water travels through an underground water distribution network to provide green cooling to an non-domestic air-conditioning area spanning 1.7 million m2 and consisting of offices, schools, MTR stations, shopping mall, hospital and Cruise Terminal.


Innovative air-cooling systems that replaces non-renewable resources with cleaner ones

The DCS’s cooling capacity of 284MW helps the community save up to 85kWh in electricity consumption per year and achieving a high level of energy efficiency with less space while maintaining a comfortable, livable environment. The DCS received the LEED Gold Certificate for its sustainable features.
