With its energy-efficient escalators, natural skylights, and raised roof for better ventilation, Woodlands MRT station has become the first train station in Singapore to be certified environmentally friendly.
These "green" features, which also include toilet taps that reduce the rate of water flow, were rolled out progressively over the past year.
For its energy and water efficiency, among other things, the station earned a Green Mark (Gold) award from the Building and Construction Authority.
On Tuesday, National Development Minister Khaw Boon Wan, an MP for Sembawang GRC, officially launched the station as Singapore's first eco-friendly one.
The Green Mark scheme recognises buildings for being environmentally friendly.
To be certified, a building has to meet at least five criteria, which include environmental protection and indoor environmental quality.
President and chief executive of SMRT Corporation Desmond Kuek said the company wants to adopt this model of green operations at its other MRT stations and retail space.
The Straits Times understands that the operator is studying if other existing, above-ground stations have a shot at getting the Green Mark certification.
When asked how green efforts would translate into cost, Mr Kuek said: "Green efforts and economics have to go hand in hand. When we make decisions... we will ensure that environmental and economic sustainability are well-balanced."
