Implementation of a district cooling system on the Punggol digital district in Singapore

ENGIE will design the integrated district cooling system (30,000 tons of refrigeration, 105 MW) that will serve both the Jurong Town Corporation (JTC), the Singapore Institute of Technology (SIT) and community facilities. This facility will centralize the cooling needs of the Punggol Digital District and thus optimize energy consumption.

Project objectives

This project aims to deploy an interconnected district cooling network to serve both the Jurong Tower Corporation (JTC) and Singapore Institute of Technology (SIT) development and community facilities. This network will have to meet the stringent energy efficiency requirements of the digital district and will have a total cooling capacity of approximately 30,000 tons of refrigeration (105 MW).

Detailed project description

In March 2019, the group was selected by SIT and JTC Corporation (JTC) to design the

30,000-ton district cooling system for the new campus, the Punggol Digital District.

The Punggol Digital District is the first district in Singapore to adopt a unique integrated master plan approach, bringing together a business park, a university and community facilities. The goal is to create synergies, enable integration between industry and academia, as well as drive strong and vibrant communities. As the flagship of Singapore’s Smart Nation, the district will be home to burgeoning sectors in the digital world, such as cyber security and digital technologies, and will comprise an open innovation ecosystem.

As the first district cooling system to meet the requirements of the Platinum Green certification, which sets sustainability standards for buildings in Singapore, the energy efficiency of the Engie-designed facility is an important factor in the design. The integration of JTC’s and SIT’s cooling networks allows the district’s cooling needs to be centralized, thereby reducing energy consumption and carbon footprint.

Emission scope(s)

on which the project has a significant impact

Scope 1

Direct emissions generated by the company's activity.

Scope 2

Indirect emissions associated with the company's electricity and heat consumption.

Scope 3

Emissions induced (upstream or downstream) by the company's activities, products and/or services in its value chain.

Emission Removal

Carbon sinks creation, (BECCS, CCU/S, …)

Avoided Emissions

Emissions avoided by the activities, products and/or services in charge of the project, or by the financing of emission reduction projects.

Scope 3 – Interconnected district cooling network

  • Quantification : 110,000 tons of CO2 avoided compared to a building-specific cooling solution

Illustrations of the project

This project develops the attractiveness of the district through its energy efficiency, for talents and new companies concerned about the ecological impact of their activity. It meets at least 3 objectives: the creation of job opportunities for young people, the financing of basic infrastructure projects and the fight against global warming

A project that can be duplicated without too much difficulty. We are already doing it on other projects in other countries

projects in other countries (Italy, USA, …).

The reproducibility of this project is not subject to any technical constraints.

Through this project, a partnership between ENGIE and JTC-SIT has been established.
