Developing Underground Space: A View From Singapore

Key considerations to set a sustainable course


Figure 1 – The illustration above shows underground space usage in Singapore. The electrical substations, which are connected to the underground cabling network, currently reside at the ground level but can be housed underground.
A common services tunnel in Marina Bay houses utilities together in a common corridor. Also in Marina Bay, there is an underground district cooling system, which centralizes the production of chilled water that is piped into buildings within the district to support their air-conditioning systems; it has helped customers achieve significant energy savings. Plans call for the rollout of more district cooling systems over time.
