Mapletree locks in SP Group for HarbourFront cooling network

The 5-building link will slash 13,700 tonnes of carbon and save 5% in annual costs.

Mapletree Investments and Mapletree Pan Asia Commercial Trust have appointed SP Group to design, build, and operate a new Distributed District Cooling (DDC) system in Singapore.

The DDC system will interconnect five buildings – Bank of America HarbourFront, the new HarbourFront Centre, the existing HarbourFront Towers 1 & 2, and VivoCity – supplying chilled water through three injection nodes.

It is expected to be 8% more energy-efficient than the National Environment Agency’s Minimum Energy Efficiency Standards for water-cooled chilled water systems in industrial facilities upon full implementation, Mapletree said in a press release.

In addition, the system is projected to save more than 5% in annual cooling-related expenses with an installed cooling capacity of 17,150 refrigeration tonnes. It will also reduce carbon emissions by about 13,700 tonnes over the 20-year operating period.

The DDC network will be implemented in two phases, starting in 2027 and is targeted to be fully operational by 2031.

The project is expected to be one of Singapore’s largest brownfield district cooling deployments.

Reaching the people who run Asia's businesses is harder than it used to be.

Inboxes are crowded. Attention is short. The executives you most want to reach — the founders, CFOs, and operators who actually move budgets — are the hardest to find through the usual channels. If you're building a company, a category, or a reputation, you already know this.

We've spent twenty years building the room they read. Singapore Business Review is where senior decision makers in Singapore and across Southeast Asia come for business coverage they can't get elsewhere — in print, online, and in person at the summits and roundtables we host across seven markets.

If you have something these readers should know about — a point of view worth publishing, a product worth their attention, an event worth their time — we'd like to hear what you're trying to do.
