Sustainable Cooling at Tampines – Singapore’s First Town Centre to Be Retrofitted With District Cooling

  • SP Group, supported by Temasek, Tampines Group Representation Constituency (GRC) and the Ministry of Sustainability and the Environment (MSE), will install and operate distributed district cooling at seven buildings in Tampines Central by 2025


Singapore, 18 April 2022 – Tampines will be Singapore’s first town centre to be retrofitted with an interconnected, sustainable cooling solution designed by SP Group.

Seven existing buildings across the town centre – Century Square, CPF Tampines Building, Income At Tampines Junction, OCBC Tampines Centre 2, Our Tampines Hub, Tampines Mall and Tampines One, will be retrofitted to plug into this novel distributed district cooling (DDC) network, which is specially engineered for brownfield developments to provide the same cooling comfort while saving energy and lowering carbon emissions at the same time. The network will be completed and operational in the first half of 2025.

Signing the supply agreement at Our Tampines Hub earlier today, and becoming the first batch of building owners to join the network were CapitaLand, CPF Board, Frasers Property, NTUC Income, OCBC Bank, and People’s Association. The signing ceremony was witnessed by Mr Masagos Zulkifli, Adviser to Tampines GROs, Minister for Social and Family Development, Second Minister for Health and Minister-in-charge of Muslim Affairs. The event is held in conjunction with the CleanEnviro Summit Singapore and the Singapore International Water Week organised by the National Environment Agency and PUB respectively.

Instead of constructing a new centralised cooling plant, a DDC utilises existing in-building chiller plants that have been carefully evaluated. A few injection nodes are then selected based on their existing excess cooling capacity and superior energy efficiency factor.

By connecting the injection nodes through a piping network, the rest of the buildings can obtain chilled water for their cooling needs, thereby doing away with the need for their own chiller plants completely. This in turn optimises the installed cooling capacity, ensures chiller systems operate at maximum efficiency, and leads to more benefits including reducing equipment costs and freeing up leasable space.

Of the seven buildings in Tampines plugging into the DDC network, Century Square, Our Tampines Hub and Tampines One will serve as injection nodes. In addition, SP has signed a Letter of Intent (LOI) with Ascendas Reit to design, build, own and operate the chiller plant at Telepark. This will ready Telepark to be a potential injection node for the network to serve future demands.

All in, this brownfield cooling network will help the town centre reduce its carbon emissions by 1,359 tonnes annually, equivalent to removing 1,236 cars off our roads. It will also achieve energy savings of more than 2,800,000 kilowatt-hour (kWh) annually, which can power more than 905 three-room HDB households for a year.

The realisation of this green solution was brought about through a partnership between Tampines GRC, MSE, Temasek and SP Group, with the strong support of building owners. It comes just eight months after a successful feasibility study of brownfield distributed district cooling was published in August 2021, affirming the various parties’ commitment to the nation’s sustainable development.

Mr Masagos Zulkifli, Adviser to Tampines GROs, Minister for Social and Family Development, Second Minister for Health and Minister-in-charge of Muslim Affairs said: “The significance of this project should not be overlooked because it illustrates how sustainable solutions can be integrated to transform existing townships. In international forums, pressure to show and prove commitment to adaptation and mitigation for climate change is mounting. This project is therefore crucial to Singapore given that a significant proportion of our building stock today will continue to exist in 2050. The energy and cost savings, as well as reduction in carbon emissions enjoyed by building owners prove that with the right solutions, doing good and doing well are not mutually exclusive and will address our challenge posed by climate change.”

“Novel sustainable solutions such as distributed district cooling can help scale practical and sustainable benefits not only for cities, but also for businesses as well as communities around the world. We will continue partnering like-minded organisations and businesses to catalyse breakthrough technologies that mitigate the impact of the climate crisis, and pave the way to a low-carbon future,” said Dr Steve Howard, Chief Sustainability Officer, Temasek.

SP’s Group Chief Executive Officer, Mr Stanley Huang, said, “The widespread implementation of low-carbon technologies like distributed district cooling can make a significant contribution towards Singapore’s climate ambitions. We are encouraged by the strong support from building owners for this sustainable cooling solution, which will contribute towards Tampines’ Eco-Town ambitions and will also create a long-term sustainable impact for Singapore’s built environment.”

The introduction of a brownfield DDC at Tampines supports the Singapore Green Plan 2030, which is a whole-of-nation movement to advance Singapore’s national agenda on sustainable development. Cooling contributes to Singapore’s annual carbon emissions, as air-conditioning can utilise up to 50 per cent of a building’s energy consumption. With more than 80 per cent of Singapore’s landscape being brownfield, a wider application of such a sustainable cooling solution will contribute towards the energy goals under the Green Plan and Singapore’s climate targets of reaching net zero by or around mid-century.

In addition to the energy savings and reduction in carbon emissions, the DDC network will provide building owners combined life-cycle economic benefits of up to $50.8 million over 30 years. Through interconnection across the various buildings, the DDC will also reduce the current unutilised cooling capacity by up to 42 per cent, freeing up chiller plant gross floor area (GFA) that can be converted to commercial and lifestyle spaces.
