District Cooling & Heating

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.

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.

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 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

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

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 rooftops 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.

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

SP Group (SP) has secured a bid to build and operate a state-of-the-art district cooling and heating system for the new International Sports Park City – an integrated development with commercial, residential and leisure spaces in Chengdu, China. The sustainable cooling solution will be enhanced with an ice thermal energy storage system that will strengthen its reliability and performance. This is SP’s first deployment in China of such a system. With an installed cooling capacity of 9,800 refrigeration tonnes, this project will be SP’s largest district cooling system in Chengdu when operational in 2025.

• Enables energy savings of 2,900 MWh annually
• Reduces carbon emissions by 1,700 tonnes
• Delivers greater energy efficiency of over 30% for cooling and over 50% for heating

Building on successful projects in Chengdu, SP Group acquired Shudu Center’s existing chiller plant to optimise it for district cooling and heating. The mixed-use development is equipped with a 7,000 refrigeration-tonne cooling and heating system that ensures efficient energy consumption and a sustainable way to work and play in comfort.

• 7 commercial, retail, and office buildings
• Covers a land area of 4,400 square metres

SP Group and Banpu NEXT have entered a joint venture to design, build, own and operate a cutting-edge district cooling system at Government Complex Center Zone C in Bangkok, Thailand. As SP’s first district cooling project in Thailand, the integrated development will have a total cooling capacity of up to 14,000 refrigeration tonnes and is expected to achieve results equivalent to removing about 20,000 Internal Combustion Engine cars from the roads over 20 years.

• Total gross floor area of 660,000 square metres
• Reduces carbon emissions by up to 3,000 tonnes annually
• Achieves 20 per cent in energy savings per year
