Smart green underground metro station in Singapore

ABSTRACT

A metro system is normally designed for an operation life of 100 years or above. Thus, a smart, energy-efficient metro system should be designed to cater for potential changes in passenger flow and passenger comfort needs. In Singapore, the Land Transport Authority (LTA) has put much effort in driving the use of innovative systems and the latest technologies to achieve smart green underground metro stations. This paper provides a brief introduction on the Building and Construction Authority Green Mark Rating and the various energy-saving initiatives that have been implemented recently in Singapore metro stations. More studies and exploration of green design engineering solutions, such as the use of fuel cells to replace the uninterrupted power supplies (UPSs) etc. will be carried out as part of the LTA’s continuous efforts to improve the energy efficiency of its metro station.
