Hong Kong Kai Tak District Cooling

District Cooling, Kai Tak, Hong Kong, Energy

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.

To help Hong Kong stay on track of its sustainability goals, Veolia develops innovative air-cooling systems that replaces non-renewable resources with cleaner ones, while still meeting municipal needs and maintaining a comfortable, liveable environment.

The Veolia Solution

Veolia’s first-of-its-kind District Cooling System in Hong Kong brings energy and cost savings to a dynamic mixed development area.

Veolia designed and built Hong Kong’s first District Cooling System (DCS) to provide air cooling to the Kai Tak district, using chilled seawater as a cooling medium to replace traditional air-conditioning systems. The DCS brings efficient cooling to an area consisting of various commercial and institutional buildings.

In a pilot project commissioned by the Electrical and Mechanical Services Department (EMSD) of Hong Kong, Veolia developed a first-of-its-kind, large-scale centralised air conditioning system in the Kai Tak district, the former site of the Hong Kong Kai Tak Airport. Chilled water travels through an underground water network to provide cooling to an area spanning 1.7 million m2 and consisting of offices, hotels, schools, shops and the Hong Kong regional cruise hub. The DCS’s cooling capacity of 284MW is derived from seawater, helping the community save up to 85kWh in electricity consumption per year and achieving a high level of energy efficiency with less space. The DCS received the LEED Gold Certificate for its sustainable features.
