District Cooling & Heating

District Cooling & Heating for Sustainable Operations

District cooling and heating systems are centralised energy systems which help buildings, districts, and townships improve energy efficiency, lower operational costs and reduce their carbon footprint.

As Singapore's largest district cooling operator, SP Group designs, builds and operates district cooling systems for customers across the region. These include Marina Bay in Singapore, the world's largest underground district cooling network and Raffles City Chongqing, the largest shopping mall in Chongqing, China. 

What is District Cooling and Heating?

District cooling and heating is an energy-efficient urban utility service that distributes chilled or hot water and supply air-conditioning to a network of buildings, providing comfort and reliability while reducing carbon emissions.


Key Benefits

Instead of individual buildings having their own chillers, district cooling reaps the benefits of economies of scale by consolidating chiller and heating capacity, operated and maintained by our expert operations team.

With attributes similar to public electricity supply, district cooling is an energy- and economically-efficient urban utility service. It presents attractive value propositions to building owners:

    • Round-the-clock availability and support
    • On-demand flexibility
    • High supply reliability
    • More space for alternative use
    • Lower initial and recurrent operating costs
    • Platinum Green Mark Certification
    • Energy assessment on existing and potential savings

Key Projects

Marina Bay District
World's largest underground district cooling network

Situated in Singapore’s Marina Bay financial district, the cooling network has achieved zero supply disruptions since 2006. As one of Singapore’s Top 50 Engineering Feats, the network will be expanded and connected to five more buildings to extend the same reliable and sustainable solution to other buildings in Singapore’s core financial district.

  • 23 commercial office buildings, hotels and retail malls
  • Expanding to 28 buildings by 2025
  • Reduces carbon emissions by nearly 20,000 tonnes annually


Tampines Eco Town
Singapore's first brownfield district cooling project

In highly developed cities like Singapore, majority of land has been built up and individual building owners are already equipped with their own chiller plants. With Distributed District Cooling (DDC) network – an interconnected, centralised cooling system – existing towns and districts may now be able to enjoy a more sustainable way to cool.

  • 7 commercial and community buildings
  • Reduces carbon emissions by more than 1, 359 tonnes annually

STMicroelectronics (AMK)
Singapore's largest industrial district cooling project

In partnership with STMicroelectronics (ST), SP Group (SP) will design, build, own, and operate Singapore's largest industrial District Cooling System (DCS) with a cooling capacity of up to 36,000 refrigeration tonnes. The estimated project value of $370 million USD over 20 years, will help the manufacturing company save 20 per cent on cooling-related electricity consumption annually.

  • 5 industrial buildings
  • Reduces carbon emissions by more than 120,000 tonnes annually

Tengah Town Centralised Cooling System
Singapore's first centralised cooling public housing township

In collaboration with the Housing & Development Board, SP Group will be bringing its first large-scale residential centralised cooling system to Tengah, Singapore’s first smart energy township. Chilled water will be centrally produced from interconnected modular chiller plants built on the roof tops before it is distributed to residential and commercial units for air-conditioning. The centralised cooling system will also be serviced by SP, bringing greater convenience to residents living in Tengah.

  • Provides cooling for up to 18,000 households across 3 districts
  • Residents can enjoy as much as 30 per cent energy savings

Raffles City Chongqing
District cooling and heating in China

An advanced energy-efficient cooling and heating system was designed and built for Raffles City Chongqing, an iconic integrated development, spanning 1.12 million square metres, comprising a shopping mall, a hotel, office towers, residences and service residences. 

  • A megastructure featuring a suite of 8 buildings 
  • Reduce energy consumption by more than 40 per cent, compared to conventional building's chiller plants
